How to adjust the cross – line mentality

Today, the first day I go to work, I’m sorry to say that I am undoubtedly a thunderbolt in a sunny day.

Early to get up and set out to go to work, on the way through a vegetable market, to see the people and cars coming and coming, thinking that everyone has their own life and work: housewives, students, career people, retirees. Each person’s time will not be treated well, a good use is the king.

After the interview, immediately to work, ignorant after the work ignorant to listen to the explanation, in the time of drowsiness let me work directly, oh mom, understand me, in fact, I want to direct operation to impress ~ ~ ~

For the first time, there are many opportunities to learn. For example, writing soft text is also in it, learning how to write headlines is to be seen and the content is clear and concise. The mystery of this is how to master and use it.
Adjustment of the mentality is also very important, the previous work is not by the side of the electric business: young teachers, clerks, so the difficulty of learning to improve greatly, please all walks of life to provide the mind to adjust the mind chicken soup, or poison chicken soup also Oh, all into the future adjustment mentality goal!

Requirements for installation of rubber tension test machine

Rubber tension test machine is mainly used in polymer materials, such as rubber, plastic and woven materials such as tensile test, loaded on the reverse device, and can also be used as compression test. Then, then come to see the installation requirements of the rubber tension test machine with Ji’nan.

1. Installation

The main body of the rubber tension test machine and the dynamometer should be installed on the basis of the concrete. The base size, according to the shape and the foundation of the foundation, will be set aside for the foot screw and the wire rod of the lower jaw and other wires to install the pipe.

The upper surface of the foundation should be leveled and leveled with a horizontal ruler. When the foundation is dry, the test machine will be installed again.

(1) installation and preliminary accuracy correction of rubber tensile testing machine.

The body and the dynamometer are carried on the basis of the concrete. The distance between the main body and the dynamometer is adjusted according to the shape and the foundation map, and the direction is adjusted. Then the thin block of iron can be inserted into the main body and the bottom of the dynamometer (and the base), and the square level instrument of the 0.05/1000 precision is used to find the correction respectively.

The preliminary finding of the subject

In the two different positions of the two vertical columns, the square horizontal meter can not be measured with a square horizontal meter, and the vertical and horizontal two position of the square horizontal instrument can be found on the outer surface of the oil cylinder, and the sag of lead can be found.

The accuracy of the rubber tension test machine

After the preliminary accuracy of the test machine is found, the initial running test is carried out after the oil pipe, the power supply and the oil are poured, and the accuracy of the test machine is then corrected when the test car is in good condition.

A square horizontal instrument is used to work on the working platform to find the plumb line of the positive oil cylinder, adjust or increase the cushion iron below the machine seat, so that the error should not exceed 0.10/1000.

When the precision of the test machine is found, the whole space under the frame is filled with cement slurry to keep the machine base well combined with the cement base to prevent the non – level of the test machine from vibration in the process of use.

After the anchor nut is poured, it is not allowed to tighten the nut and operate the testing machine before the cement is dry. (cement drying time is usually not less than 10-15 days) after the cement is completely dry, fasten the good luck foot nut, check the accuracy of the installation of the test machine, whether it is in line with the accuracy of the test. If the non conformity should be re searched.

In the use of tension test machine, because the vibration of the test is easy to produce loose phenomenon, so the tension test machine should be fastened after a period of time.

2. Take over

When installing the oil pipe connected with the dynamometer, wash the kerosene inside the tubing and ensure the cleanliness of the oil circuit. Attention should be paid to whether the gasket is complete, so as to prevent oil leakage at high pressure.

3. Selection of oil specifications

In hydraulic rotation, N68 precision machine tool hydraulic oil can be used, or other similar specifications of the oil can be used. Its kinematic viscosity is (100 degrees centigrade) 11-14 centigrade.

4, oil filling and oil discharge

Open the air filter on the tank and pour the oil into the fuel tank. The amount of oil injected is about 24 kilograms. The specifications of the oil used can be described in the specifications of the oil. When oil is placed, open the bottom of the dynamometer to the bottom of the dynamometer. The duration of the oil use depends on the climate in various places. For example, the oil will be changed when the oil begins to deteriorate or the pollution is unused.

5. Connect electricity

The electrical device of the rubber tension test machine is in the dynamometer, the power supply is three phase four wire system, the circuit between the main body and the dynamometer is connected with the plug. The dust and other impurities in the electric box should be cleaned before the electricity is connected. After the power supply line is introduced, the “power” button on the dynamometer panel is pressed to indicate that the light has been opened. Starting power supply, at this time can press the oil pump start button, observe the direction of motor rotation, press the lifting button of the jaw seat, check the lifting action of the lower jaw seat is consistent with the text shown on the button, at the same time check whether the limit is the function of the switch.

The above is about the requirements of the installation of rubber tensile testing machine. The KRW series microcomputer controlled rubber tensile testing machine manufactured by Chuan Bai, Ji’nan, is a new generation of dual space microcomputer controlled rubber testing machine. The test machine can be divided into the door type and the single arm type structure. The design of the host and accessories can draw on the advanced technology of foreign countries. It is beautiful in appearance, convenient in operation and stable and reliable in performance. Through the control system, the computer system controls the rotation of the servo motor through the speed control system. After decelerating the deceleration system, the moving cross beam is driven up and down through the precision screw pair, and the tensile, compression, bending and shearing tests of the sample are done without pollution, low noise, high efficiency and very wide adjustment. The speed range and the moving distance of the crossbeam are also equipped with a wide variety of experimental attachments. It has a very broad application prospect in the mechanical properties test of metal, nonmetal, composite and products. At the same time, test and data processing can be carried out according to GB, ISO, JIS, ASTM, DIN and users.

Rubber tension test machine is mainly used in polymer materials, such as rubber, plastic and woven materials such as tensile test, loaded on the reverse device, but also can be used as compression test, then the next arm, Ji’nan Chuan together to see the installation requirements of rubber tension test machine!

What is the role of stainless steel mesh belt in its application

With the development of economy, the time of product upgrading is also getting shorter and shorter. The emergence of special stainless steel mesh belt has greatly accelerated the production efficiency of products. It can be said that now many products are inseparable from the production of stainless steel mesh belt, which can be seen in the production of many enterprises. So today Xiaobian will tell you what role the stainless steel mesh belt has played in the application.
In the case of the continuous development of the transportation equipment industry, the production of stainless steel mesh belt and other related products has also been further developed and applied, especially the stainless steel mesh belt has the characteristics of no need to fall off, long life, large transportation and so on, so that it has been widely used in many industries.
The stainless steel mesh belt plays the role of ventilation and transportation in the reflow welder. The good ventilation and transportation of the metal mesh belt make the transmission and air permeability of the welding machine play better, which is more suitable for the delivery of electronic products. The new material of stainless steel mesh belt has greater progress in friction performance, strength and temperature resistance than the traditional rubber material, and also ensures the service life of the stainless steel mesh belt. In addition, when using stainless steel mesh belt, we must operate according to the instructions, so as to give full play to its performance.

What kinds of oil are used in mechanical cleaning

There are many kinds of industrial cleaning agents, and their classification methods are relatively simple. They are divided into inorganic chemical cleaning agents and organic chemical cleaning agents mainly according to their chemical composition. The experts of Dongguan Hao Sen Cleaning Technology Co., Ltd. say that some cleaning agents may have different effects on different dirt according to some of them.
Or if it has two or more than two kinds of effects on the same dirt, it should be classified according to its main function under general conditions.

Suitable industrial cleaning agents are selected according to the type of oil contamination of the cleaning objects. Because of the different oil contamination, the requirements for oil cleaning agents are different.
First, during processing, due to the processing requirements (such as cooling, lubrication, abrasive, surface treatment, heat treatment, etc.), all kinds of oil stains on the metal. Most of these oils are mineral oils, including animal and vegetable oils, emulsions, polishing paste, grinding paste and various salts. This class
The composition of oil pollution is relatively simple. The time on the surface of metal is relatively short, and the adhesion force is not strong, so it is easy to remove. Therefore, it is necessary to choose a normal temperature cleaner without corrosive effect on metals, and other requirements for cleaning agents are not high. Containing fat in the selection of detergent components
Hydrophobicity based surfactants are widely used in animal and vegetable oils. Aromatic water repellent surfactants are often used in mineral oils.
Second. The oil stains on metal surfaces such as machinery and parts that are kept for a long time are mostly antirust oil, antirust grease, gas phase rust inhibitor and water-soluble corrosion inhibitor. Because the components of these oils are complex, they are tightly adhered to metal and have a long time.
It is difficult to clean up the chemical changes. It is necessary to select oil cleaning agents according to different situations. For heavy oil stains such as antirust grease, a heated cleaning agent can be used for unsealing and then cleaning. This will greatly improve the efficiency of sealing and cleaning. For thin layer oil and gas phase retarding
Corrosion inhibitor and water soluble corrosion inhibitor can be heated or two kinds of cleaning agents at room temperature.
Third, cleaning the object after operation and use of oil pollution will be more complicated. Most of these oils are made of various lubricants, fuel oil, and other industrial wastes, dust and metal powder. Due to the long time, complex operation and various factors, such oil composition is complex.
Miscellaneous, firmly attached and difficult to clean. In general, special cleaning agents should be selected for different oil composition. For example, carbon cleaning agent should be used to clean carbon in engine. The cleaning of the scale should be used as a cleaning agent.

Daily maintenance of the feeding machine

1. Daily maintenance
1, after processing, clean the table in time and keep the table and machine clean and hygienic.
2. Regularly remove stains such as rails, rack, stone powder, sawdust and other stains to prevent interference due to debris interference.
3, clean up the engraving machine’s screw regularly to prevent the screw from sticking to the foreign objects. The screw determines the precision of the machine in the equipment, and the screw also plays an important role in the transmission process.
4, regularly clean up the electrical box, the biggest killer of circuit boards when dust.

Two. Oil
Some customers often neglect the problem of engraving machine oil injection because of their busy work. Some customers do not work for several days or even weeks because of seasonal reasons, and do not pay attention to the oil work. Our work experience tells us that the oil is very important in the maintenance process of the carving machine.
1, first clean up the guide rail and lead screw, and use cloth (without hair removal) to remove the oil dirt and material scraps on the guide rail and the lead screw. Because the temperature is low, you can add oil to the guide rail and the lead screw, and the best antifreeze oil is added.
2, the fuel cycle is two times a month, that is to add oil once every two weeks.
3, if the machine is not used for a long time, it should be regularly refueling empty to ensure the flexibility of the transmission system.
4. Slowly move back and forth after the oil is added to ensure that the lubricating oil can be evenly added to the guide rail and the lead screw.
Three. The problem of spindle
Many customers often forget to add water, especially in autumn and winter. Because the outside temperature is low, the spindle motor is too hot to feel.
1, the cooling water is the necessary condition for the normal work of the spindle motor. If the cooling water is dirty, it will cause serious damage to the motor, and ensure the cleaning of the cooling water and the normal work of the pump.
2, pay attention to the water level, the water cooling spindle motor must not be water deficient, so that the motor heat can not be exported in time.
3. Pay attention to the ambient temperature. Be careful to freeze the water tank and the water pipe because of the cold water temperature.

Four. About the maintenance of engraving machine and cutting machine in winter.
1. Ensure the ambient temperature of the operation room to ensure that the temperature is above 0 degrees.
2, check the standard temperature of refueling, at least the lowest temperature.
3, when the machine is not used, if the room temperature is low, it is best to pour water out of the water tank, prevent the freezing crack spindle and the computer abnormality of the safety protection of the pipe computer, especially for the computer connected to the engraving machine, and pay attention to the cleaning of the virus.

What are the car sound insulation materials

To understand the sound insulation of the first to understand the source of noise of the car, car noise is partly from the engine, part of the vibration from the car, and another is that the environment is more than the wind. Depending on the source of the noise and the different parts of the body, different sound insulation materials are required from a professional point of view, such as the sound insulation and insulation of the hood.
Lord 2
Generally now, there are two kinds of sound insulation materials used for automobile modification, one is butyl rubber, the other is a double component (PP+PET) sound absorption cotton. Butyl rubber is the main material of the shock plate we often say, and PP+PET is the sound insulation cotton (white cotton). The sound comes from the vibration, so to reduce the noise in the box is to stop the shock first, that is to reduce the body vibration, the shock plate itself is more dense and the outer layer is covered with a layer of aluminum foil, so the shock plate can play a very good sound insulation effect. The sound is also divided into different frequencies, the two components of the sound absorption cotton are relatively fluffy and there are numerous small micropores in the middle, which mainly play a sound absorption effect. At the same time, the application of 40 grams of non-woven fabric on the outer layer of the sound-absorbing cotton can also play the effect of sound insulation, so that the noise of different frequencies is digested.
Four hundred
For the best refitting effect, the car friends can choose the shock plate and the sound absorption cotton at the same time. The general modification can also only use the sound absorption cotton, and it will also play a certain effect.

Precautions for installation of car weighing sensor

Many people now use weighing sensors, but a lot of people are in use, many people still do not know very well, especially when the installation, do not know exactly what is going on, in the state of the circle, or follow the small editor to understand the weighing sensor installation attention.
1, the weighing sensor should be light and light, especially for the small capacity sensor with alloy aluminum material as elastomer. Any shock or drop caused by vibration is very likely to cause great output error.
2. When the loading device is designed and installed, the loading force should be ensured to reclose the force axis of the weighing sensor, so that the influence of the inclined load and the eccentric load should be minimized.
3, in the level of adjustment. If the weighing sensor is used, the mounting plane of the base should be adjusted to the level by the horizontal instrument. If multiple sensors are measured at the same time, the mounting surface of the base should be kept on a horizontal plane, which is designed to ensure the strength base of each sensor. This is the same.
4, determine the rated load of the sensor according to the range of the weighing sensor in its instruction.
5, in order to prevent chemical corrosion. When installing, use Vaseline coated weighing sensor outer surface. We should avoid direct sunlight and environmental temperature upheaval.
6. Add the copper braided wire bypass device at the two ends of the weighing sensor loading device.
7. The cable should not be lengthened automatically. When it needs to be lengthened, solder joints should be welded at the joint and moistureproof sealant should be added.
8, it is best to use some baffles around the weighing sensor to cover the sensor. The purpose of this way is to prevent debris from falling into the moving part of the sensor and affecting its measuring accuracy.
9, the cable of the sensor should be far away from the strong power supply line or the place with the pulse wave, and the cable line of the weighing sensor should be separated into the iron pipe separately, and the connection distance should be shortened as much as possible.
10, according to the weighing sensor range selected in its description to determine the rated load of the sensor used, although the weighing sensor itself has a certain overload capacity, but in the process of installation and use should try to avoid such a situation. Sometimes overloading at a short time may cause permanent damage to the sensor.
11, in high precision use occasions, the weighing sensors and meters should be used for 30 minutes after warming up.

9 Tips for improving employees executive ability

Excellent execution is the key to distinguish convenience stores from competitors. Today, Xiaobian shares with you nine elements that enhance the executive ability of convenience store employees, hoping to be helpful to bosses.

1. let the right person do the right thing.

This is not only a static concept, but also to help these people grow and adapt to the new needs in their work. No system can exceed this point in terms of effectiveness. Some small convenience stores should pay special attention to the fact that convenience stores grow very fast, but some employees may not keep pace with the growth of convenience stores. If you can’t help these people grow up with convenience stores, they may become a stumbling block for the growth of convenience stores in the future.

2., we should see clearly who are strong business people and who are truly leaders.

These two kinds of people are all needed by convenience stores, but do not confuse them. The key is to tap the people with leadership, and make the decision of the convenience store to the real leadership. People who are very smart but not strong in leadership can give him other growth paths.

3. there is a very clear responsibility system

To make the staff clear, the convenience stores have what kind of expectations they have, what kind of assessment standards, employees have what kind of responsibility, to speak very specific.

4. there is a very clear “milestone” system.

It is when to do something well, what to do and who to do it. The “milestone” of each node in the development of the convenience store is done well; moreover, the “milestone” must be clear and transparent, which is crucial to the successful transformation of the convenience store.

5. supervision is very important in the implementation process.

Every small target set up in a convenience store must include a monitoring mechanism. Of course, the premise is that these small targets should be clear and transparent. What’s more, the supervision I’m talking about is not only internal supervision and observation, but also external supervision and observation (where the customers are going, what new products and new technologies are emerging from the market).

6. discover talents and cultivate talents

Leaders must know what talents are among their employees. Any convenience store can’t succeed without training and discovering talents and not understanding collaboration. Some leaders only care about numbers, but numbers are just a result. The key is to achieve such figures, which is very important for employees to make efforts.

7. collaboration

Without good collaboration, it is impossible for any convenience store to develop, and convenience store development speed, innovation, agility, these all need to be implemented through collaboration – such collaboration, not only internal collaboration, but also external collaboration. People who have better skills generally raise their positions vertically, such as upgrading him as store manager, deputy store manager and so on. Leaders also need to pay attention to those who are very good at working and emphasizing collaboration, and they should also be rewarded and commended.

8. retain talented people

A good convenience store is made up of excellent people. The convenience store itself does not participate in competition, and the competition is the convenience store. In the first year of the new employees, they should be thoroughly analyzed to see what their thinking is and how their work attitude is; put them in a very suitable position and give them plenty of room for development so that they can better retain their talents.

9. follow up tracking.

A lot of work is done by teams. It is very important to track everyone’s work and have a clear evaluation system.

The short cut is just a step in every step

One
I have a friend who has been promoted to department manager through his parents’ relationship in less than two years. In other people’s opinion, it is really lucky to have such a shortcut. But in the next few years, friends are becoming more and more powerless in their work.
Although he has a certain prestige as a manager, his employees only have superficial respect for him, and they do not obey him in private. After all, the friends are still young, the professional experience is shallow, their ability to be improved, the reaction is not too mature, and even often give his team the wrong direction of the wrong direction.
For example, he insisted that “wine fragrance is not afraid of the alley”; when it is to do the product, he put his energy on the extension business; when it is to do fine management, he insists on the extensive management model.
Having realized the seriousness of the problem, friends decided to put aside their airs and work with the grass-roots employees of the company from the most basic work. From design, production, packaging products to how to find channels, do sales and expand business, he takes every step to make up all the homework before.
Friends say that when they have the ability to become managers again, their hearts are steadfast, steady and calm.
Many of us tend to be anxious to get a promotion and pay raise when our ability is not enough. At this point, what we should do is not to concentrate our efforts on climbing up branches, but to settle down and work hard. If the foundation is unstable, it is necessary to omit the process of adding bricks and tiles to oneself. Then, even if it occupies a high position, it will be crumbling and may even fall very badly.
Two
I remember when I first started learning a car, I especially liked to add it before the speed was raised. Sometimes, when the speed is 20 yards, I add to the 4 gear. The result is that the car is shaking violently, and it will be easily extinguished.
Later, the coach taught me that we must first mention the corresponding speed, so that the power of the car is enough, and then step on the clutch, shift gears, gas door. In this way, the car will smoothly connect, and then move on.
In fact, human growth is the same as driving. At the beginning, when you use 1 gears, it is almost impossible to drive the car in 5 gears. A little progress, and then 2 gear, 3 gear forward at a uniform speed. When you are young, you read books, you have knowledge, and you finish your job, then you can go to work. But it is impossible to succeed at the very beginning.
When you are mature enough, you can change gears 4 and 5. Just like people in middle age, they can often carry on the task, bear the blame, and have some skills to climb the peak of life.
In every stage of life, there is no shortcut. If you want to grow up, you need to go all the way to experience and experience, and gradually gain experience and experience in the process.
Three
I have seen a story.
A mother, who had traveled far and wide, after many twists and turns, took her 8 year old son to find a famous writer’s residence. The mother pleaded with the writer and asked him to teach his son to write a good article which was astonishing and then let his son become famous in a short time.
The writer was very helpless, so he wrote the secret on a piece of paper and put it in the envelope, so that she could take her child home to see it.
As a result, when the mother came home, she looked at it hastily and found only three words on it.
It’s not surprising. All people have to lay the foundation for success. If you want to write a good article, you will have fluent writing, clear thinking and ingenious layout as well. In this process, the books you should read, the exercises you should do, the trial and error you should have and the attempt you have to do are equally indispensable.
Four
When I was a child, I often asked adults when they could be like them, without reading or writing homework, and playing for as long as they wanted to play.
At that time, the adults always told me that you still have a long way to go. So, I wait and wait, wait for, look forward, read the primary school, into high school, to high school, into the University, and then really grow into an adult only to discover, the original growth way, really did not drop a somersault, test less one time, less one year book.
Everything in the world has its laws, such as spring seed, summer long, autumn harvest and winter storage. When you keep your mind, don’t be in a hurry. When you work hard, don’t try to make a surprise. When you sharpen your mind, you can’t ask for a sudden enlightenment.
The more reliable your foundation is, the more complete your process is, the longer your efforts persist, and your growth will be more prone to qualitative leaps. In the end, you will understand that in this life, many things are not urgent. If you want to harvest, the pain of eating, the sweat of the stream, and the tired of it should not be less.
Some setbacks can not be avoided, some processes are not allowed to be saved, and some shortcuts are not feasible. So don’t worry, don’t panic, and don’t play smart. Believe that the quickest way to success is not to overtake corners. Every day and every year, we can finally lead a good life.

Domestic hardware enterprises attach importance to modern technology

China’s hardware industry has been developing at a high speed since the 90s of last century, and now it has become an important hardware country in the world. According to statistics, by the end of 2010, the total sales volume of China’s hardware industry reached 1 trillion yuan, and the industry market scale reached 800 billion yuan. With the extensive application of hardware in industry, agriculture and other fields, this data is constantly being refreshed.
There is no doubt that China has become a big country in hardware products, but it is undeniable that China’s hardware industry has a large gap with the world hardware enterprises in many aspects, such as product research and development, innovation, brand management, marketing management, enterprise scale, capital strength and many other aspects. Gratifying is that, under the impact of the global economic tide, the domestic hardware enterprises pay more attention to modern technology, and the speed of the integration of the hardware and the Internet technology is further accelerated.
The development mode of the entity industry and the mobile Internet convergence under the line of hardware products has been recognized by industry expert Chen Sufang. Chen Sufang believes that, relying on the advantages of the mobile Internet platform, hardware enterprises greatly widen the sales channels, and help the construction of the authoritative brand of hardware enterprises, enhance the future competitiveness of enterprises and expand the scale of enterprises.
It is predicted that in 2020, the proportion of China’s industrial added value to global industrial added value increased from 5.72% in 2000 to more than 10%. This means that there will be a large number of powerful hardware manufacturing groups in China as a support, therefore, the future of the hardware industry is broad, but the five gold industry and the integration of the mobile Internet. It will also be the inevitable trend of the development of the industry.
