In industry, a lot of processing, are widely used by us, used in some machines, in the processing, there will be a variety of properties, mechanical parts processing is the same, so what are its technological properties? Let the mechanical parts hardware processing factory’s small make-up to tell you.

(1) Casting performance: generally refers to the alloy with low melting point and small range of crystallization temperature to have good casting performance. For example, the eutectic composition of the alloy has the best castability.

(2) Pressure workability: refers to the ability of steel to accept hot and cold deformation. Good cold deformation performance is characterized by good formability, high surface quality, and not easy to produce cracks; and good thermal deformation performance is characterized by the ability to withstand hot deformation, high oxidation resistance, wide deformation temperature range and small hot brittleness tendency.

(3) Cutting performance: tool wear, power consumption and surface brightness of parts are the marks to evaluate the cutting performance of metal data, and are also one of the important basis for reasonable selection of data.

(4) Weldability: to weigh the welding performance of the data is to mark that the strength of the weld zone is not lower than that of the base metal and there is no crack.

(5) Heat treatment: refers to the behavior of steel in the process of heat treatment.

The above is the mechanical parts processing process properties, from the above text, we can know is, it has what kind of technological properties? And to the processing, how to bring the effect, want to know more information in this respect, please pay attention to the mechanical parts hardware processing factory.

Hardware processing is often encountered by us, but also very popular with enterprises, because processing can make the product more functional, price is also higher, to bring greater benefits to enterprises, so it will be so popular reason, and we are in hardware processing It is also necessary to formulate its operating procedures to prevent unnecessary trouble in the work. So, let’s let Xiaobian understand the safety operation procedures of hardware processing as follows:

1、 Before entering the operation post, all employees shall check whether their clothes meet the operation requirements. It is forbidden to wear slippers, high-heeled shoes and clothes that affect safety. Those with long hair should wear safety helmets. Insist on correct posture during operation, and have enough energy to carry out operation. If you find that you are not feeling well, you should leave the post immediately and report to the leader. During the operation, it is necessary to gather the thinking, do not chat and cooperate with each other. The operator should not operate in the state of irritability and fatigue to avoid accidents and ensure the safety of operation.

2、 Before mechanical operation, check whether the moving part is filled with lubricating oil, then start and check whether the clutch and brake are normal, and operate the machine tool idly for 1-3 minutes. It is strictly forbidden to operate the machine in case of mechanical failure.

3、 When changing the die, the power supply should be closed first. After the moving parts of the press stop working, the device can be started and the mold can be debugged. After the adjustment of the device, move the flywheel by hand twice to check whether the upper and lower dies are symmetrical and reasonable, whether the screws are consolidated, and whether the blank holder ring is in a reasonable position.

4、 It is necessary to wait for all other personnel to leave the mechanical operation area and take away the sundries on the working platform before starting the power supply.

5、 After the machine is started, one person will transport materials and operate the machine. Other people are not allowed to press the electric building or step on the pedal switch board, nor can they put their hands in the mechanical operation area or pull the moving parts of the machine with their hands. During the mechanical operation, it is forbidden to extend the hand into the sliding block operation area, and it is forbidden to take and place the workpiece by hand. It is necessary to use the standard when taking and placing the workpiece in the die. In case of abnormal sound or machine failure, the power switch should be closed immediately for inspection.

Now the scientific and technological ability is constantly updated, and the economic capacity is getting better and better. Therefore, there are more and more opportunities for Dongguan machining in the society. At the same time, there are many products that will use processing technology, because processing can improve the function and service life of products, but we There will be deformation during machining, and it is also the most annoying thing that we often encounter in our work. So, let’s let Xiaobian know what causes the deformation of machining as follows:

1. When the tube is cut open, bending deformation will occur, especially for stainless steel;
2. When the central position of the part is hollowed out, the stress and deformation will occur;
3. The deformation of bakelite, POM / PE / PEEK and other engineering plastics materials is caused by excessive cutting amount or high processing temperature;
4. The welding steel parts have not been properly and scientifically aged;
5. Due to improper process setting, the deformation of the subsequent process is produced.

In a mechanical equipment, mechanical equipment is not only composed of machinery, but also its accessories. Without accessories, other things will not survive. Automation accessories is one of them, so how to maintain automatic parts is the best? Let the mechanical parts hardware processing factory’s small make-up to tell you.

1. Keep away from heat

If the temperature of the starter piston is too high, it is easy to cause overheating, burning and melting, causing cylinder lock; the rubber seals, V-belt, tires, etc. are overheated, which is easy to be aged, performance degradation and shorten the service life; the coils of starter, generator, conditioner and other electrical equipment are overheated, which is easy to be burned and scrapped.

1. Avoid dirty

If the parts such as fuel filter, oil filter, air filter, hydraulic oil filter and all kinds of filter screen are dirty, the filtering effect will become worse. If parts such as radiator of water tank, radiator of cylinder head and cylinder head of air-cooled engine and radiator of cooler are too dirty, it will lead to poor heat dissipation and high temperature.

1. To avoid rebellion

The cylinder pad of the engine can not be installed reversely, otherwise it will lead to premature ablation and damage of the cylinder pad; the fan blade of the starter can not be reversed; for the tire with directional pattern and herringbone pattern, the air mark behind the device should make the herringbone tip point to the rear.

1. Avoid lack

The air lock of the engine should be installed in pairs. If it is missing or missing, it will lead to the valve out of control and damage the piston and other parts; the connecting rod bolt, flywheel bolt, the opening pin, locking screw, safety plate or spring pad of the device on the bolt of the transmission shaft of the engine shall be installed to prevent loosening. Once the installation is omitted, serious problems may occur in the application. The timing gear chamber of the engine is used for smoothness Once the oil nozzle of gear is missing, it will cause serious oil leakage.

The above is how to maintain the automatic parts is the best, as long as according to the above method, to carry out maintenance can, in the process of use, to avoid such problems, so that it does not occur accidents, want to know more information, please pay attention to mechanical parts hardware processing factory.

In a processing, the most important thing is the material. Good materials can naturally make good things. If the materials are not good, how can we make good products? Automatic parts processing is one of them. What materials are used for automatic parts?

The most common steel and baking paint for general shell

For steel with rigid requirements, better S45C + plating and soldering should be used

Aluminum a6063 + anodizing may be the most commonly used for simple parts

Because the density of aluminum is about 1 / 3 of that of steel, it is light and rust proof, and it is beautiful and wear-resistant after anodizing.

Of course, some places need to use soft materials, such as nylon, bakelite and saigang.

The above information is what kind of materials are used in automatic parts processing. There are many kinds of materials, not only one kind, but also many kinds. Each kind of material is different, which will bring different performance and effect to the product.

With the development of economy, the use of stainless steel has become more and more extensive. People’s daily life is closely related to stainless steel. However, many people do not know the function of stainless steel, nor do they know the protection and maintenance of stainless steel. Most people think that stainless steel will never rust. In fact, the reason why stainless steel has excellent corrosion resistance is that a passive film is formed on the surface, which exists in the form of more stable oxide in nature. In other words, although the degree of oxidation of stainless steel is different according to different operating conditions, it is eventually oxidized, which is generally called corrosion. So, what are the identification methods of stainless steel parts? Today, let our precision hardware machinery manufacturers to take us together to understand it!

Stainless steel parts processing manufacturers inform you that stainless steel refers to the steel which is resistant to weak corrosive media such as air, steam, water, acid, alkali, salt and other chemical corrosive media, also known as stainless acid resistant steel. The following several stainless steel identification techniques for our reference.

1. Liquid medicine detection method: at present, there are several chemical solutions for detecting stainless steel on the market. When one drops on the surface of stainless steel, 201 turns dark brown and 304 turns red.
2. Price estimation method: fully understand the market situation of various steel grades. If the prices of the same steel grade differ greatly, it is necessary to consider whether they are “Li Gui”.
3. The integrity of traders: in the market, enterprises with good integrity will do so. It is better to select more traders for comparison, which is also a way to prevent “Li Gui”.
4. Contract agreement law: stainless steel parts processing manufacturers inform you that in the purchase and sale of stainless steel, large amount of contract should be signed, indicating the steel type, quantity, raw materials, time, delivery time, violation of laws and regulations responsibilities. When the raw materials are inconsistent, they can be recovered by negotiation or by law.
