The development trend of bathroom hardware is to establish standardization

[Abstract] for years, the bathroom hardware enterprises have adopted the custom-made non standard production and marketing mode, which are basically made by hand, and the pure handmade form is not assembly line, and the production can not be standardized.
Distribution is the base of development

Distribution is a strong brand of bathroom hardware enterprise brand must be a strong way, bathroom hardware in the domestic development process is relatively short, and the non standard production of bathroom hardware, also restricted the distribution of bathroom hardware enterprise distribution speed, so the number of dealers and high quality, who can win the market.

Analysis on the distribution pattern of the development of China’s bathroom hardware

Distribution network layout design should consider the length and width of the channel. Exclusive distribution is the narrowest form of distribution channel. It refers to the choice of only one dealer or agent in a certain area and a certain time to grant exclusive management. The channel length refers to the number of channel times required for the goal of the completion of the enterprise. Eyes. The building materials industry generally chooses a flat channel for exclusive distribution, which is more suitable for the exclusive distribution in the developed provinces. The provinces in the less developed provinces are distributed exclusively by provincial agents, so the distributors have a strong sense of responsibility and enthusiasm, and less channel conflicts occur, so as to manage and concentrate resources to do a good job of brand.

Standardization is the inevitable trend of development

For many years, bathroom hardware enterprises have been using the custom-made non standard production and marketing mode, which are basically made by hand, and the pure handmade form is not assembly line, and it can not be standardized. As a result of no standardization, a door hole size one specification, very clever and very scattered, do a lot of ring in the process, the chance of a lot of mistakes, a little careless, we should all waste. At present, the sanitary ware orders exported to abroad are all standard bathroom hardware, and dozens of containers have one or two specifications.

Insiders said that the standard bathroom hardware ensures product quality while minimizing the decoration cycle. Standardized products can improve efficiency and make factory production more orderly, ensuring that products can compete better in brand marketing.

Analysts pointed out that China’s bathroom hardware market is a big cake, but also the last piece of cake in wood products. Whether it is hot commercial housing or large-scale construction of affordable housing, as long as it is hardcover repair room, must be standardized bathroom hardware products to decorate. Standardization is the inevitable trend of the development of bathroom hardware.

The trend of network customization is obvious

As the security and privacy guarantee of the family, the importance of the door is self-evident, and there is also one of the most expressive ornaments of the indoor stereoscopic effect, which can properly reflect the taste of home decoration and the aesthetic tendency of people. With the improvement of material living standards, life tastes are constantly improving and personality is constantly highlighted.

In the whole interior decoration, the door is one of the elements of extensive and profound Chinese culture. The high level consumer likes to customize more and more. The bathroom hardware manufacturers, I know, are getting more and more old and carved pieces of hardware. To make niche market, we must make use of the Internet. The same is true for bathroom hardware, because it can solve both the cost of distribution, the cost of opening a shop, and the individual needs. 10% of the home furnishings industry has a large space for development, and will grow at 20%. Customization is not just home, but also flooring, doors and so on.

RC Monster Truck

If anyone reprints the article in this column, it must be licensed by the original author Bamboo and “famous car”. Otherwise, any reprint and reference are embezzled.

In the Transformers 2, there is a robot that collects information and is called “Wheelie” for unlocking work. He will become a remote control model car after it is deformed, and the remote model car is not a fictional plot of the film, and it does exist in the real world with the big tyres. Live vehicle type big foot remote control model car (short: big car, or RC Monster Truck)!

I believe you have seen the “monster wagons” of the United States on television to squash the small bridge cars or leap the number of cars. In fact, this time we introduced the big foot remote control model car (hereinafter referred to as the big foot car) is made by the American “monster truck” as the prototype. The madness of the remote control cart is no less than the “monster truck”. It can even make a more difficult and exaggerated move. The remote control big foot car is not picky to the road, the mud ground, the grass, the sand, the flat road and so on all kinds of pavement big foot car can be easy to face, fly earth slope, rock climbing, 360 degrees in the air after the landing big foot car master, known as the remote control model car in the “multifaceted”! In addition to strong road adaptability, the speedway has no weakness in the acceleration of straight lines. The high-performance remote control Bigfoot can break through 75 kilometers / hour. The acceleration is even more amazing. The acceleration of 0-75 km / h can be completed within 3 seconds. Absolutely can let the streets of the car can not catch up!

As the name suggests, “big foot” is the meaning of big wheels, and the remote control vehicle with big wheels has strong performance. In addition, the big foot car is agile, flexible, with the sturdy frame of the big foot car, the efficient hydraulic shock absorber, the big torque power equipment, even if it is a leap 70 degrees slope or wading over the barrier big foot can also be done easily! No wonder the US military has to use remote control Bigfoot to undertake investigation. The big foot remote control model car can be divided into two types of electric and oil big feet according to the power source. The proportion of the more popular big foot cars is 1/8. Most of the domestic mainstream cars are imported products, such as the HPI Savage series, the TRAXXAS series and the Team Losi series, all have a large number of fans. Every week at the end of the week, the big foot car fans will gather in Together, carry out activities.

Compared to other remote model cars, big feet can be said to be the most free, freest and most indulgent. Players can run on the meadow, challenge the limits of the muddy road, and even the players take the big foot car to the extreme sports ground and the X-Game lovers. Put the big foot car in the car tail box, where to play where to play, the big foot car brings you not only the stimulation of the remote control car, but also the wonderful experience of unrestrained and comfortable, can relieve the pressure of the busy work of modern people!

Some brushless related knowledge and common RC car Brushless

With the decline of brushless prices and the rise of domestic brushless, the brushless era is getting closer to our RC model players, but there are also a lot of people who don’t know much about the brushless.

One, what is brushless?
The so-called brushless, that is, no carbon brush, is used to distinguish from the general brush motor.

The conventional motor, that is, the brush, is usually fixed to the motor, using the motor cover and the motor, fixed the rotor of the winding (usually 3 wings), and then through the brush and the rotor head contact, the conductance to the rotor, producing a mutually exclusive magnetic field, so that the rotor rotates.

Without brush, the permanent magnet magnet is made into the rotor, and the winding of the coil can be changed without brush, and the change of the magnetic field of the coil can be changed to drive the rotor to rotate.

As a result, the brushless motor needs 3 wires to connect to the motor, because it needs to adjust the magnetic field of the coil, and the brush motor only needs 2 lines to the motor, because the rotor’s magnetic field is automatically converted when the rotor rotates. Therefore, there are brushes, not brushless; brushless electricity can not generally use brush, but also some brushless power can support the brush motor, the specific reference to the parameters of electrical adjustment.

Two, what is inner rotor brushless and outer rotor brushless?

The so-called inner rotor, is the coil around the motor outside, the rotor into a bar, fixed in the motor, is the inner rotor brushless motor, see GTB motor.

While the outer rotor is placed inside the coil winding, the magnet is made into a special shape and rotated around the inner coil on the outside. There are many examples. Just like the fan inside the computer, the outer rotor is brushless.

Our car brushless motor, usually the inner rotor brushless motor, does not require a special torque, high speed; and the outer rotor is especially suitable for the aircraft, the torque is large, especially suitable for the needs of 3D flight.

Add a small point, on the motor angle problem, whether there is brush or brush, there is an angle problem, can refer to this post: http://bbs.rcfans.com/viewthread.php? Tid=98030

Three, what is the KV value? What is the number of T? What is R?

Brushless parameters are generally marked with KV values. The KV value is the speed indicator of brushless motor, which means the value of motor speed increases with increasing 1V voltage.

For example, 4000KV brushless, loading the general car with lithium 8V around, the speed of 4000*8=32000 turn (23T brushes about this speed), so the current competition allows the 4000kv brushless and 23T in the same game.

Like the brush motor, the value of the coil winding is T, or R (NOVAK is expressed by R, and many others are represented by T). Generally, the number of brushless T (or R) is equivalent to that of 2 times the number of brushes. For example, 3.5T brushes are equivalent to 7T brushes (specific principles and why no brush often has “.5T” T before Himalaya brothers explained in a post in the trolley area, I forgot the title of the placard, and now it cannot be searched out).

The same brand, the T number and the KV value are generally fixed, unless the manufacturer improves, and different brands, the T number and the KV value is not necessarily linked, such as LRP 3.5T is more than 9000 KV, and NOVAK 3.5R is more than 10000 KV. I think the main difference between the output power and the power of the motor is that the speed will not be very different. This is what physics teaches. In fact, I haven’t compared it.

Vehicle brushless system, I recommend a gentle way to play more, RV with 2S lithium battery is good, even 4000kv, speed is also good. If two people play with a trolley, 23T will continue to fight for 10 minutes. 11.1V voltage is not very suitable for use in the car, blindly increasing the voltage to improve the speed of brushless motor, although it may make the car’s tail speed high, but not to improve the technology and speed of the loop, we are not just to run straight to the straight line right? In fact, I don’t like the way to sacrifice everything for a straight line. Driving technology is not good, the faster the speed, the faster the loss, the longer the car repair, the higher the cost.

Four. Brushless and brushless Brushless

Quote Comrade JOVI’s original saying: “brushless electric modulation must know the current position of the rotor before it can output the appropriate current to drive the motor. The sense is to sense the rotor’s current position (phase) by inductor mounted on the motor. Without sense, there is no inductor, and the electric current depends on the power line to judge the rotor phase. (see http://bbs.rcfans.com/viewthread.php? Tid=112452 for details)

There is a sense of phase, so the linear is much better than no sense of sense. All the players who have no sense of feeling are well aware that the usual brushless start is less linear and even a bit more violent, but there are some non sense linearity, such as the homemade wolves series non sense series, and the other NOVATECH products in China. Cards, according to friends who work in the KYOSHO plant, low speed linearity is

How to look at the auto parts industry？

The market has great potential and strong post – development. The following contents will not have any data support, but I will give my personal opinion based on my experience in the industry. The auto parts industry is the post market of the automobile, which is equivalent to the house needs decoration. The normal life of each vehicle is at least 10 years, and the more maintenance the vehicle runs, the more constant it is. The car popularity rate is obvious to all, after nearly 10 years of growth and precipitation, the car factory for the Chinese market for the development of a very large number of vehicles, 2 year of a small change of 4 years and more and more functional subdivision positioning has been the car factory in response to the market instinct, this is also the consumer happy to see. Of course, some people are happy and sad. Of course, the consumers are happy. For the car factory, it is called the explosive product, and it can not be sold as a strategic product (partner). For parts manufacturers, they love to hate, the good sales model is large but the profit is not good but stable (the parts of this type are very competitive in the bidding), the cost of bad sale is difficult to recover, and the accounts are not good (the parts manufacturers with insufficient cash flow do not like to receive the OEM order). It is more difficult for auto parts distribution (especially wholesale). The result may be this: the manufacturer keeps the blanks in the new car parts and keeps the stock pressure on the distribution in order to recover the cost of the development. But the result is bad for both sides, which has proved that funds have been seriously eroded and the money can not be recovered smoothly (triangle debt you know). All that is said is that we want to emphasize the joy and sorrow brought by the rapid popularization of vehicles to the auto parts industry. The more resources, the higher the demand for management. But the development of auto parts industry is more chaotic. The early auto industry can run a lot, but the current industry needs to be careful and calculate every money, because the money is calculated, not a pile of goods.

What industry is auto parts

Auto parts are the manufacturing industry.

See below:

Manufacturing industry refers to the manufacturing resources (materials, energy, equipment, tools, funds, technology, information and manpower), according to the market requirements, through the manufacturing process, into the use and use of large tools, industrial products and consumer products industry.

Manufacturing industry directly reflects the productivity level of a country and is an important factor to distinguish between developing and developed countries. Manufacturing industry occupies an important share in the national economy of the developed world (developed countries).

According to the material form used in production, the manufacturing industry can be divided into discrete manufacturing and process manufacturing.

The manufacturing industry includes: product manufacturing, design, raw material procurement, warehousing and transportation, order processing, wholesale operation and retail. Assembly and installation activities of machinery and equipment for product sales in enterprises (units) which are mainly engaged in product manufacturing.

New advantages of traditional hardware industry

According to customs statistics, the total import and export volume of China’s hardware industry reached 128 billion 20 million US dollars in 2017. Among them, the total import and export of three traditional industries, such as building hardware, tool hardware and daily hardware, reached 42 billion 233 million dollars, 23 billion 190 million US dollars and 16 billion 444 million US dollars respectively. In the hardware eleven categories of commodities, they accounted for 64% of the total import and export of the hardware industry. Data show that the import and export growth of hardware three traditional industries also reached 11.25%, 10.73% and 3.50% respectively, showing a trend of “stabilization to better”. With the growth of the world economy and the improvement of the domestic economy, the traditional hardware industry will meet the opportunity of change. It is expected to achieve great leap forward in the aspects of structural optimization, technological innovation and quality improvement.

Both import and export data have been restored to positive growth

The data show that in 2017, the construction hardware industry completed the total export volume of 29 billion 974 million US dollars, up 11.49% and 23.9 percentage points from the same period last year, and completed the total import amount of 12 billion 259 million US dollars, a year-on-year increase of 10.65%. The tool hardware industry has completed the total export volume of 16 billion 219 million US dollars, up 14.26% from the previous year. The growth rate is compared to the previous year. In the same period, 15.15 percentage points increased, and the total amount of imports was 6 billion 971 million US dollars. The growth rate increased by 3.29% and 0.46 percentage points over the same period. The daily hardware industry has completed the total export volume of 15 billion 344 million US dollars, up 2.71% from the same period last year, and increased by 5.96 percentage points from the same period of last year. The total import amount is 1 billion 100 million US dollars, up 1 from the same year. 5.94%. The growth rate increased by 12.84 percentage points over the same period last year.

According to monthly data analysis, the import and export of the three traditional hardware industries showed a steady upward trend throughout the year, and the average level in the second half of the year was obviously higher than that in the first half year. From the way of trade, the proportion of the general trade mode of the building hardware industry and the tool hardware industry is increasing, and the growth rate is over 10%. This will help the enterprises to increase the value-added of the export, improve the profit of the enterprises, and further optimize the trade structure of the industry; the speed of the daily hardware industry is the lowest in the eleven major commodities of the hardware. It’s only 2.47%.

From the trade object, the object of trade is more diversified, in the consolidation of the United States and the European Union, Japan and other traditional markets at the same time, exports to Brazil, India, Russia, South Africa and other “BRIC countries” and “The Belt and Road” many countries along to achieve rapid growth.

It is worth noting that, from the import and export price comparison, the average import price of most of the products is higher than the export average, except for the drilling tools (with cermets) for the hardware of the daily hardware. Among them, the average price of the imported lighter, diamond drilling tools, barber equipment, sawing parts, drilling tools, flashlights and other lighting appliances is more than 10 times the average export price. Improving the added value of products as soon as possible is still the direction of the industry’s overall efforts.

Traditional industries still face challenges

Although the three major traditional hardware industries have made more satisfactory answers in trade in 2017, the challenges facing the industry still remain, and we need to accelerate the pace of transformation and upgrading and structural adjustment in the face of a fierce market competition.

First of all, with the disappearance of demographic dividend, the low cost competitive advantage of enterprises is gradually disappearing. Second, trade friction has become the norm and trade frictions are diversified because of over reliance on exports. Third, the appreciation of the renminbi in major trading countries also has an impact on import and export trade.

Despite the challenges, the traditional hardware industry has been promoted in a full range of cruel competition for many years, and the overall compression ability of the industry is more powerful than that in the past. Under the guidance of national policies, it is expected to break through the bottleneck and enter a new realm of development.

The policy leads the traditional industry to take off

With the introduction of several opinions of the general office of the State Council on creating a good market environment for the special action of “three products” in the consumer goods industry, the hardware industry has carried out a series of achievements in improving quality, brand and efficiency. The World Bank expects global economic growth to rise to 2.9% from 2.7% in 2017, with the international monetary fund raising its global economic growth expectations by 0.1 percentage points to 3.7%, with the International Monetary Fund up to 0.1 percentage points up to 3.7%. The traditional hardware industry will usher in a new round of high quality growth this year, and will lay a more solid foundation for future development.

Marketing mode of hardware for doors

In recent years, the competition in the hardware market is becoming increasingly fierce, and the drawbacks of traditional sales channels are gradually exposed. In order to gain a dominant position in the competition, the hardware enterprises actively explore new marketing models, and the promotion of the Internet, the sales channels of the hardware industry are increasingly diversified. This is a good thing. The hardware enterprises can effectively integrate the advantages of various channels, and then borrow their strength to avoid various kinds of risks effectively.
Marketing methods:
First, store operation: high cost and high dependence
In recent years, hardware sales channels are still concentrated in stores, and hardware companies with certain strength and reputation have accelerated the pace of entering large stores. People in the industry believe that the choice of brand hardware in the brand store door stores, on the one hand, want to use the strong appeal to build their own brand influence; on the other hand, it also takes into account the market environment, marketing and service system and so on easy business operation.
However, with the increasing rents of stores and the continuous opening of stores, the cost of raw materials and logistics is also increasing. The rising cost brings the high cost of hardware industry channels. In the relationship between hardware and stores, enterprises can not help but rely on a number of helplessness.
Two, private shop: Economic and human cost increase
In recent years, more and more hardware enterprises focus on the operation and management of independent stores. The chairman of a hardware brand said: first, the standard store is to enhance the service platform, and the two is to restrain the bad behavior of the stores through the unified price system.
Through unified system quality assurance, after sale service unified standard, as well as the common concern and supervision of the public, this is the store mode we want to build.
As a matter of fact, the opportunity and adjustment of the self run shop mode coexist, the development of the self run shop is like a double-edged sword. The economic and human cost of the channel of the self run shop will also become an important factor to test the development of the enterprise.
In today’s society, the cost of human resources for a store is also increasing. Similarly, the support and training for each store is also an important input in cost. The higher the cost of unit number and the higher the cost of unit sale, it seems to be a vicious circle of channel.
Three, tooling channels: the money needs to be prudent
The commercial housing of many cities is changing from rough housing to refined decoration.
The proportion of hardware products in refined decoration projects is increasing. Construction projects have become a very important channel to promote hardware products.
Four, e-commerce channels: both advantages and disadvantages are half innovative and breakthrough
In the treatment of emerging e-commerce channels, some hardware enterprises think that the performance of e-commerce is relatively poor, material, details, installation effect and so on can not be displayed, the whole hardware business e-commerce has this limitation.
Others believe that the electricity supplier must be a new business model in the future.
The channel chain, like the flow of water, flows from the distributor to the terminal and eventually flows to the consumer. It is always in line with the direction of future development to grasp the current consumption habits of consumers.
Many hardware companies began to test the water business channel, but at present no one has explored a suitable method and mode for development.
Future hardware companies should also explore more models, including ways of expression. Efforts should be made to break through the limitations of the exhibition so as to achieve certain breakthroughs in the way of expression of e-commerce system.
The diversification of the marketing model has further promoted the growing competitive development of the channel cost and the homogenized products, and weakened the competitiveness of the hardware enterprises in the terminal market. Therefore, the importance of the channel construction is becoming increasingly apparent. The new direction of the transformation of hardware enterprises.

Automobile parts quality and safety demonstration area was officially launched.

Recently, the preparatory meeting of Ningbo Yinzhou export hardware and tools, automobile parts quality and safety demonstration zone was held in Yinzhou District. The conference discussed the two system documents, such as “Yinzhou export hardware tools, the implementation plan for the construction of the demonstration zone for the quality and safety of auto parts”, “Yinzhou export hardware tools, the supervision and management methods for the quality and safety demonstration zone of automobile parts and parts”, and made clear the division of responsibilities of the small members of the leading members of the demonstration zone and the demonstration of the demonstration. Area check and acceptance related requirements. The convening of the conference marks the official launch of the two provincial demonstration zones for the export of hardware tools and auto parts in Yinzhou.

As the gathering place of the hardware industry, Yinzhou District has 1135 production enterprises with a total output value of 25 billion 900 million yuan. The product covers more than twenty thousand kinds of hardware products, hardware tools, daily hardware and so on. With the continuous upgrading and development of the products, the hardware tool production enterprises continue to promote the development of high technology and information technology in the hardware industry with the help of electronic information, new materials and other high-tech industries, and use new and high technology to transform the traditional technology to realize the continuity, automation and product quality of the production processes. Great progress has been made in the fields of microelectronics biotechnology, equipment technology, network technology and information technology. The overall technical level of the hardware industry is in the leading position in China, and some areas have achieved international leading position. By the end of 2017, there were 1135 hardware tools production enterprises in Yinzhou District, with total output value of 25 billion 900 million yuan, total import and export about 1 billion 500 million US dollars, more than 5 metal products employees, 3 well-known trademarks in China and 19 provincial export brands, which had grown into one of Yinzhou District’s pillar industries and became the national scale ahead of time. The hardware product distribution center with full function and strong radiation has gradually developed into the national hardware and technology development research and pilot base, the hardware product information center and the technical exchange center.

In 2016, the auto parts industry has become the highest sales industry in Ningbo. It is also the first advantage and pillar industry of Yinzhou District, and also the export base of Ningbo. By the end of 2017, the total number of auto parts enterprises in Yinzhou District was over 500, with a total output value of over 25 billion yuan. Among them, there were 205 auto parts enterprises with export delivery value above the scale, with total output value exceeding 16 billion 700 million yuan and 19 thousand employees, with 24 hundreds of millions of enterprises, 60 50 million enterprises, 35 high-tech enterprises and 2 countries. There are 13 provincial-level enterprise technology centers. Yinzhou auto parts industry develops and produces all kinds of products. It covers all four kinds of 60 categories, including automobile power assembly, automobile chassis, body and accessories, electrical instruments and related parts. It covers the major automobile assembly, especially with the characteristics of machined parts, rubber and plastic parts and stamping parts, which has formed the industry. Characteristic cluster and high degree of industrial agglomeration. At present, auto parts enterprises have 12 export brands, of which 1 are export brands, 3 are municipal export brands, and 8 are district level export brands.

In view of the characteristics of Yinzhou automotive hardware tools and auto parts industry, the Yinzhou inspection and Quarantine Bureau will establish a series of convenient service measures in the next step. The risk management of imported goods in the demonstration area should be implemented, and the results of the third party inspection should be vigorously promoted, and the traceability mechanism for the quality and safety of export commodities should be explored. Local governments will be encouraged to invest in special funds to build demonstration zones and demonstrate the effectiveness of the demonstration area. The export hardware tools and automobile parts quality safety demonstration zones are made into new business cards made in Yinzhou.

Grasp the current situation of hardware accessories industry

Grasp the current situation of hardware accessories industry and start from the analysis of market development prospects.

Although the development of construction machinery is good, China’s hardware accessories rely on imports, so as to meet the needs of China’s hardware accessories.
At present, China’s hardware industry is in a high stage of operation, and hardware enterprises show a prosperous situation. However, the matching parts are like a rope that holds the neck of the enterprise, making it difficult to eat and eat. Ma Chuanwei, the Secretary General of the construction machinery accessories Branch of China Engineering Machinery Industry Association, has been visited recently. He asked him to talk about the existing problems in China’s engineering machinery accessories industry and to analyze its development prospects.

Hardware accessories
Restriction of supporting parts
At present, in my view, especially small hardware has broad market prospects, the market of small dig is very clear. In addition, the market of small construction machinery such as lifting arm forklift, skid steer loader, two head busy and so on will also have great development in the process of nurturing. But so far, small pumps, valves, hydraulic parts and other supporting parts are basically dependent on imports. And foreign companies, the first to meet the needs of their domestic enterprises, second to meet the needs of foreign enterprises in China, the third is to take into account the needs of local enterprises in China. The role of this bureau in the construction machinery production enterprises in China will become more and more obvious. This year, in China’s construction machinery enterprises, there is a year and a half for the foreign matching enterprises to pay the money for up to one and a half years, such as Hefei Zhenyu, such as Zhenyu; there is something to be loaded, and a valve, but the Japanese enterprises are not able to supply the goods, such as jade machinery; last year, the machinery of Xu dug, the Japanese enterprises at the beginning of the year, the end of the end of the end of the end of the end of the end of the end of the end of the end of the end of the end of the end of the end of the end of the end of the year. Or no delivery, resulting in zero output of the excavator. Not only can the supply period be guaranteed, but at the same time, the price of the full set of hydraulic system purchased from abroad is generally not negotiable, and the development of domestic engineering machinery enterprises is greatly restricted by the factors such as pre sale and after-sales service.

Choose a breakthrough
In view of the overall development level and current situation of China’s engineering machinery, Ma Chuanwei suggested that small excavation and other small construction machinery accessories should be used as a breakthrough to promote the overall development of the construction machinery accessories industry in China.
At the annual meeting of China’s engineering machinery accessories industry, the director of Ma Chuanwei and the subsidiary part suggested that the manufacturer should focus its attention from just focusing on the small excavation kit to other small engineering machinery accessories, taking the small dug matching kit as a breakthrough, and promoting the comprehensive development of other small engineering machinery Suites.
To realize the comprehensive development of small engineering machinery assembly including small dig, the realization of its hydrostatic transmission is an important link. At present, in small construction machinery, such as small wheel loader, excavating loader (two busy), sliding steering loader, telescopic boom fork loading, and small tonnage forklift, the required hydraulic parts for static pressure transmission are mostly imported. Internationally, most of the loaders in the advanced countries below 3 tonnages have achieved hydrostatic transmission, and almost all the loaders with annual output of more than ten thousand units in China are hydraulic transmission. At present, the only domestic production of static pressure transmission accessories only Shandong Longtai, this private enterprise can produce 3 tons of static pressure drive loader, but it is only the start of production, not mature, production is also the whole machine.
In addition to the key technology, Ma Chuanwei believes that the other important aspect of the gap between China’s construction machinery accessories hardware and foreign products lies in its reliability. It is reliable to produce ten pieces or eight pieces in small quantities. Product reliability is related to management, process equipment and process route. Generally speaking, the main factors that affect the reliability of China’s supporting parts are raw materials, especially steel quality. Domestic construction machinery enterprises are generally not large in scale, and special orders are required for steel mills. There is also a gap between technology and equipment and foreign countries. There are flexible production lines abroad, and every procedure is strictly controlled. There are also problems in heat treatment. The reliability of the supporting parts produced is not good, which leads to the quality of the main engine can not be improved. If the construction machinery products produced by foreign enterprises are generally the first failure for 1000 hours, our products will have only 400 or 500 hours. If the reliability problem is not solved, users will not buy it even if it is sold cheaper.
If we do this, the current situation of the mechanical parts of my country will be greatly improved, the demand for import will be gradually reduced and the rapid development of our country’s economy will be promoted.

Practical skills of Huiyang CNC Machining plant

Usually, we carry out CNC deep hole machining for a part. First, the CNC programmer analyzes the design drawings of the parts, determines the processing plan, and then selects a point on the workpiece as the original point of the coordinate system, which we call the program coordinate system and the program origin.

The determination principle of this point is easy to determine and convenient programming calculation, generally coincides with the process datum or design datum of the part, so it is also called the workpiece origin, and the coordinate system is also called the workpiece coordinate system. NC programming is based on workpiece coordinate system, and parts machining is done on CNC lathe.

Now we can see that there is no connection between the workpiece coordinate system and the machine tool coordinate system two. In order to link the two, we need to operate the cutter. Let’s take a look at the specific method.

The first is to get the workpiece coordinate system directly by input the cutter offset value through the tool setting. This method is easy to operate and has good reliability. The workpiece coordinate system will not change as long as the cutter deviation and the mechanical coordinate system are not changed. Even if the blade is replaced, the workpiece coordinate system is still in the original position, and the power break and restart the machine tool will not affect the position of the coordinate system.

The second is to specify a value to set the workpiece coordinate system in the program after G50. After the knife, the point on the tool, such as the tip of the knife, can be moved to the coordinates of the G50 set.

The third method is to use MDI to set six coordinate systems, G54~G59, which can change its position through the zero point offset value of the external workpiece or the offset value of the workpiece zero point. Three methods to change the zero point offset value of the external workpiece or the offset value of the workpiece zero point are input from the MDI panel, programmed with G10 or G50, and input with external data.

With the development of numerical control technology, CNC machine tools are widely used. A skilled double head CNC operator must master the basic skill of tool setting. In actual production, the efficiency of tool setting and tool setting error directly affect the efficiency of NC machining and the accuracy of machining parts.
