The difference between sheet metal processing and stamping

Today, Xiaobian mainly introduces the difference between sheet metal processing and stamping processing.
1. The stamping process is the production technology of the product parts with certain shape, size and performance by using the power of conventional or special stamping equipment to make the sheet material directly deformed and deformed in the mold. Sheet metal, mold and equipment are the three elements of stamping process. And sheet metal processing is metal sheet processing. For example, making use of plate to make chimneys, iron buckets, oil tank oil pot, ventilation pipe, big head of bend head, Tianyuan place, funnel shape, etc. the main working procedure is cutting, bending and buckle edge, bending forming, welding, riveting, etc.
2, the stamping process can be said to be a process in the process of sheet metal processing, for example, batch production of the pipe elbow with scissors, cutting the efficiency will be very low, if the blanking die with the blanking die directly on the punching machine processing rate will be very high.
3. Sheet metal processing is a comprehensive cold processing technology for sheet metal (usually below 6mm), including shearing, punching / cutting / composite, folding, welding, riveting, splicing, forming (such as car body). Its remarkable characteristics are the same thickness of the same parts. Generally, the basic equipment includes a scissors, a CNC punch press, a plasma, and a plasma. Water jet cutting machine, compound machine, bending machine and all kinds of auxiliary equipment, such as uncoiler, leveling machine, deburring machine, spot welding machine, etc.
4, stamping processing is divided into two ways: cold stamping and hot stamping. This depends on the strength, plasticity, thickness, degree of deformation and equipment capacity of the material, and the original heat treatment and final use conditions of the material should be considered.
5, stamping process can be divided into two categories: separation process and forming process (bending, drawing and forming).

Quality is the ultimate sword for subsequent successors

A few days ago, a customer friend came to my shop and did not ask for several products directly. He did not pay. What are the customers thinking about? What are you hesitating about? Worry about the quality! At about 5 p.m., I actively contacted the buyer to remind us to pay in time. I could also deliver the goods on the same day. I sincerely chatted with him, not surprisingly, because he bought the product at the other house last time. Then we went to Wangwang to chat, and I photographed the physical drawings to the customers, and finally paid the goods. Logistics was also very fast. At noon on the third day, the buyer received less than half an hour’s delivery, and then went on to place a larger order. Thank the customers and friends for their trust and support! In fact, we think about empathy, we often shop online, unhappy shopping happens. So we must be patient with every customer friend.

Basic introduction of textile machinery

Textile machinery is the processing of natural fibers or chemical fibers into various mechanical equipment needed for textiles. Although the production of chemical fiber machinery, including a variety of chemical machinery, is now considered to be an extension of textile machinery, a broad textile machinery. The process of processing different fibers, such as cotton, hemp, silk and wool, is different and some are completely different, so the machines needed are all kinds and various. Textile machinery is usually classified according to the production process, including spinning equipment, weaving equipment, printing and dyeing equipment, finishing equipment, chemical fiber drawing equipment, silk reeling equipment and non textile equipment. Spinning equipment is divided into two types: short fiber processing and long processing fiber. Cotton and cotton type synthetic fibers belong to staple fibers, such as wool, linen and silk.
Mixed fiber is a kind of long fiber. Two types of fibers have different processing procedures, and the equipment can not be used, but some machines have similar design principles. Even if the structure of the same type of equipment is similar to that of the machine, it is generally not universal because of the nature of the material and the final requirements for the fabric.
Textile machinery is the means of production and material basis of the textile industry. Its technical level, quality and manufacturing cost are directly related to the development of the textile industry.

Hardware industry sales need patience

Why others can pick up orders, and you always linger here.

Why do people earn tens of thousands or even hundreds of thousands of dollars a month, and you can’t be ordinary.

Why others can buy new customers back, but you can’t.

Service is fundamental, and secondly, it has advantages over quoted prices.

Quality assurance, quality first.

The hardware processing industry is no more than other industries, if a customer identifies your home.

It can be ordered in factories in a few years, which is also different from the fast moving products industry.

Although the hardware industry does not have fast – moving industry orders, it is fast.

But an order is the volume of the whole quarter.

The processing industry needs to be patient and let the customers trust us.

The client’s observation now leads to subsequent orders.

A lot of time to pay patience, after all, think back, if customers trust us to support us, we can ensure long-term cooperation!

What are the reasons that affect the efficiency of CNC machining

CNC machining is a process method for machining parts on CNC machine tools. It is an effective way to solve the problems of variable parts, small batch, complex shape, high precision, high efficiency and automatic processing. In recent years, with the increase of new products and the increase of the complexity of parts, numerical control processing has attracted more and more attention from enterprises, and has become a decisive factor for manufacturing enterprises to win the market competition. However, most of the manufacturing enterprises have low numerical control processing efficiency, so it is of practical significance to study how to improve the NC manufacturing level by High Efficiency NC machining technology and improve the sustainable development ability. What are the reasons that affect the efficiency of NC machining?

1. Equipment failure
Because the CNC system is complex in principle and precise in structure, it can not repair and troubleshoot in time after failure, so it will affect the efficiency of production. CNC machine tool is a kind of advanced processing equipment with high automation and complex structure. In order to give full play to the superiority of the machine tool, the quality of the technicians and the civilized production are particularly important.

Two. Production management
Because of the complex system of numerical control equipment and various types of equipment, it has brought great difficulties to the application and programming of technicians and operators, which greatly restricts the processing of parts. Program management is not perfect, processing procedures are repeatedly compiled, which not only wastes time, but also affects the instability of programs. A prominent problem is that the performance of numerical control equipment is not understood, and many parts that are not suitable for NC machining or other types of work are also numerically controlled. So the numerical control machine not only does not produce its efficiency, but also destroys the precision of CNC machine tools.

Three. Process technology
Most of the time, due to the fact that the procedures cannot be followed up in time, the technology of drawing data is not perfect, and the time of inspection has become a factor affecting efficiency. Most of the process technology does not combine the rationality of the process with the suitable CNC machine tools, tools, and fixture, so that when the machine tool is processed on the workpiece, there will be a equipment stop waiting or unqualified product as long as there is a problem in the process.

Four. CNC cutting tools
As an important auxiliary tool to participate in manufacturing activities, the tool system plays an important role in the flexibility, productivity and precision and accuracy of the manufacturing of the CNC machine tools. In the production environment with more CNC machines, a large number of tools are needed to flow and exchange frequently between tool banks and machine tools, and between machine tools and machine tools. The different management users of traditional tools are not easy to grasp the information of the tool, resulting in the confusion of the use of tools, waste of resources and low production efficiency. The more serious results are the excessive deviation of the work in work, the deviation of the process, even the waste of the products and the production cycle.

Five. Personnel skills
The technical and advanced requirements of the CNC system are very high, requiring the operator to have more extensive professional knowledge, such as organic, electric, liquid and gas. Therefore, the quality requirements for the operators are very high. But the common problem is that the quality of the numerical control operators is not high enough, and some problems do not know how to deal with them. They are often not found in the maintenance manual and may have never been met before. This requires the users to have a high quality, calm the problem, clear mind, strong field judgment, and of course, have a more solid numerical control basis.

Six. Product structure
(1) the sizes and structures of all kinds of parts are quite different. The machine tools and other process equipment are not universality.
(2) many companies are usually faced with many varieties, small batch, short production cycle of production tasks, so the process system is required to have a higher response speed.
(3) product parts are complex in structure and difficult to process.
(4) thin wall, easy to produce processing deformation. There are many thin-walled and deep cavity structures, which are typical weak rigid structures.
(5) the selection of cutting tools and cutting parameters is difficult. Because of the development and application of the new material, and the lack of support for the processing and cutting database, how to select the cutting tools and select the processing parameters scientifically has become a difficult problem.
(6) the choice of cutting oil is difficult, there are a large number of cutting oil products in the market, and the quality is uneven. Because of the lack of oil experience and data comparison, the use of oil products that do not meet the requirements of the process will cause a decline in the processing efficiency.

The application rate of galvanized drum is generally higher in various industries

Galvanized roller is now used in all walks of life, the popularity rate is high, and then the specifications and models of galvanized drum are numerous. How do users choose their own galvanized rollers in a wide variety of models?
The structure and principle of this type of equipment should be understood first in the selection and purchase of galvanized roller. Following the mechanism and principle of the galvanized roller produced by Dongguan Shun Cai Yi Industrial Co., Ltd., the structure principle of the YZ type oil cooled galvanized roller, when the motor drives the eccentric sleeve, the cycloid gear is swinging, and the force is passed to the needle tooth. Pin, the eccentric sleeve turns a circle cycloid gear to move the pin pin or tooth, or two teeth to make the drum speed down and rotate.
When running, the pin shaft, pin bush and pin tooth sleeve of the pin tooth pin make the dynamic friction become rolling friction. The bearing parts of the product are made of bearing steel. High accuracy, long service life, low noise and high rotation efficiency.

In the cavity of the oil cooled galvanized drum, the motor with a circular radiator is supported by the left and the right. The axle head of the YD type two lanes is fixed on the support outside the roller, and the square axle of the DY type blue axis is fixed on the belt conveyer. The motor spindle rotation drives certain external gear and a pair of internal meshing gears to make the drum speed down and rotate. In the inner cavity of the cylinder, there are cooling lubricants. When the drum is rotated, the oil will be able to scour the motor shell to cool and lubricate the gear and the bearing roller. The main parts are the roll body initial car, the primary school static balance, the axle head interference assembly welding, the fine car and the fine alignment balance and so on. If the behavior tolerances such as roundness, cylindricity and straightness are below 0.2mm, after grinding, the external cylindrical grinder or the roller grinder should be grinded. If the surface hardness is required, the heat treatment process needs to be increased. The galvanized drum is classified according to size, such as a large roller, such as paper machine (over 10 meters in length, more than 1500mm in diameter), and a small type of roller (usually within 1 meters long) for the belt conveyed on automatic line (generally within 1 meters), and the diameter is also divided by the function, so as to ensure the accuracy of transmission, such as The roller on the digital laser printer has the press roller on the paper machine, such as the press roller on the paper machine. There is a support roller for the small size precision, the roller with heat exchange, and the heavy sprocket roller also has the heavy pressure filter roller, etc.
Outside the motor, Cao Yong and the support directly or divided form, through the axis 9S or liquid power coupling 9S drive the input shaft rotation, the power into the inner cylinder, the reduction principle is the same as the YZ galvanized drum. Because of the external motor, it solves the problem of heat dissipation of the large power motor well, so that the power of the drum can be greatly improved.
Structure principle of galvanized cylinder with type external loading
The outer part of the motor is connected with the bearing, and the power is transmitted into the cylinder through the input shaft. Drive an external engaging gear and a pair of internal meshing gears to make the cylinder speed down and rotate. When the drum rotates, the coolant lubricates the gears and bearings.

The difference between pure titanium and titanium alloy

The density of titanium is 4.5g/cm3, 57% of steel, titanium is less than two times heavier than aluminum, and its strength is three times larger than aluminum. When the ratio of strength to density is compared with that of different materials, the specific strength of titanium alloy is almost the largest in common industrial alloys. The specific strength of titanium alloy is 3.5 times that of stainless steel, 1.3 times of aluminum alloy and 1.7 times of magnesium alloy, so it is an essential structural material for aerospace industry. The comparison of the density and specific strength of titanium to other metals. Titanium has high melting point, poor thermal conductivity and electrical conductivity, similar to or slightly lower than stainless steel, titanium has superconductivity, and pure titanium has a superconducting critical temperature of 0.38.4K. Metal titanium is a nonmagnetic material.
Titanium alloy is a phase solid solution composed of single phase alloy with small density, both in general temperature and in high practical application temperature, all of which are a phase, the microstructure is stable, the wear resistance is higher than pure titanium, and the anti oxidation ability is strong. At the temperature of 500-600 degrees, it still maintains its strength and creep resistance. It can be enhanced by heat treatment. It has good thermal strength and thermal stability, good welding performance and good performance at room temperature, ultra low temperature and high temperature.
Commercial pure titanium is a compact titanium metal with titanium content of not less than 99% and containing a small amount of impurities such as iron, carbon, oxygen, nitrogen and hydrogen. The most influential impurities in the mechanical properties of pure titanium are oxygen, nitrogen and iron, especially oxygen. The reaction of hydrogen to titanium is reversible, and the effect of hydrogen on titanium is mainly “hydrogen embrittlement”, which usually stipulates that the hydrogen content should not exceed 0.015%, which contains 0.15%-0.3% oxygen and 0.03%-0.05% nitrogen. The industrial pure titanium is a six square lattice at room temperature, but its axis is small (c/a=1.587). It has better processability. The molding and welding properties of pure titanium are good, and it is insensitive to heat treatment.

Six advantages of a concentrated melting furnace

1. the burning burner with low excess air coefficient is used to reduce the oxidation burning loss. The oxygen sensor of the furnace can be installed according to the needs of the customer, so as to further control the oxygen content in the furnace, and the burning loss of the material is less than 1.2%.
The 2. tower structure, the flue gas in the retaining room and the melting room are all discharged from the feeding port. The maximum heat efficiency of the furnace is raised to a maximum, and the heat consumption per ton of aluminum is less than 520 thousand calories.
3. the electrical control system adopts imported components with high automation and stable operation.
4. aluminum liquid measurement protection tube is adopted by Japanese Hitachi metal Salong imported sheath. The service life is not less than 18 months. The melting and atmosphere measurement uses a ceramic sheath thermocouple. The life span of the die casting parts is more than two years.
The 5. feeder control adopts frequency conversion speed regulation, runs smoothly and reliably, and effectively protects reducer and feeder.
The automatic flue gas discharge system can be installed in the oven chamber above 6.ATM-750, which not only improves the thermal efficiency of the furnace, but also ensures the balance and stability of the furnace pressure.

Closet handle material

This kind of part is very common in life. Whether it is a wardrobe or ordinary cabinet, without the handle part, it will not be so convenient to use. So, do you know what kind of material the cabinet handles have? Below Xiong Hushan hardware Xiaobian to give you a good introduction to several different cabinet handle materials.
Cabinet handle
Stainless steel hand material
The cabinet door handle what material good, the first choice to use stainless steel cabinet door pull hand, and stainless steel material in home decoration is also the most used a material, such as stainless steel cupboard, stainless steel kicking line and so on, because the stainless steel has no rust advantage, so in the choice of cabinet door when the choice of hand, can be selected. Select the stainless steel cabinet door pull hand to try, in addition, the stainless steel hand design is also very delicate and delicate, simple fashion, smooth and bright, can meet the requirements of home decoration.
Material of aluminum alloy drawing hand
Second kinds of door handle material is aluminum alloy, aluminum alloy is also a widely used material in the market, in the scope of application, compared to stainless steel cabinet door pull hand, aluminum alloy cupboard door handle may be slightly inferior, but aluminum alloy also has its own unique advantages. In quality, the quality and durability, super long use, never fade; in the technology, the use of multilayer electroplating technology, so that the surface of the cupboard door more refined; in the price, also very valuable, the door handles what material good, aluminum alloy is also good oh.
Copper hand material
The copper handle is also an important reference point when you choose to buy the door handle. High quality copper and simple ancient charm make you enjoy the luxury of classic and fashion.

Automatic lathe accessories hole machining tool kind of left drilling better

When it comes to automatic lathe fittings, hole machining tool left drill is a tool that must not be lacking in automatic lathe production. The left drill belongs to a kind of twist drill, but it is very different from the twist drill. The difference is that the spiral groove of the twist drill is right-handed, while the spiral groove of the left is left, the common left drill is divided into plating. Titanium left drilling in the left of tungsten steel, titanium plating left drill is also the high speed steel left drill, and tungsten steel left drill is the hard alloy left drill. Today, the small editor mainly wants to tell you about the characteristics of the two left drills.

Titanium plated left drill is a very common drill for automatic lathe. It is suitable for drilling holes, and its material is high speed steel M35, M42 and so on. There are many kinds of materials suitable for processing, such as copper, iron, aluminum, stainless steel, etc. all can be used, the cutting quality is very stable, in the price ratio, if not for some high hardness and hard cutting material, most of the small series will recommend the material of high speed steel material OBS titanium plating left drill!

The difference between the left drill of tungsten steel and the titanium plating left is that when the material is high hardness and difficult to cut, the titanium plated left drill can not be processed with high quality, and this time you can choose to use the left drill with tungsten steel, the tungsten steel is the hard alloy, the hard alloy is much higher than the high speed steel in the hardness, as long as the high quality is selected. Cemented carbide adopts some high quality production technology. The quality is convenient because titanium plating is left drilling. But high quality is a high price. I hope you will be clear about that.

The quality of the left drill of titanium plating and the left drill of tungsten steel is better. It is certain that the quality of the left drill of tungsten steel must be better, but the two sections have their own differences. It is not necessary to discuss their quality. In fact, the difference between the two are very large in different processing conditions, each of them has a great difference. The different processing range and the corresponding processing environment, and the different environment can depend on that left drill more suitable. So these two kinds of left drills do not need to be divided, because they are coexisting.
