Related To The Development Of Stamping Parts
As the stamping parts has such advantages, punching in the national economy
, a wide range of applications in various fields. For example, in aerospace, aviation, military, machinery, agricultural machinery, electronics, information, railway, telecommunications, transportation, chemicals, medical instruments, household electrical appliances and light industry sectors where there punching. Not only have used it throughout the industry, and everyone directly into contact with the stamping parts products. Such as aircraft, trains, automobiles, tractors, there are many large, medium and small stamping parts. Cars of the body, frame and rims and other parts are punching out.
With the advancement of science and technology, especially computer technology, are also under development with the stamping parts, have our unpredictable future development.
Stamping parts is a regular or special stamping parts equipment by means of power, so that the die in sheet metal forming force and be directly affected by deformation, and thus obtain a certain shape, size and performance of the product components of production technology. Sheet metal, stamping parts dies and equipment are the three elements. Stamping parts is a metal cold deformation processing methods. So, is called cold stamping parts or metal forming, stamping parts short. It is the metal plastic forming (or stamping partsu processing) is one of the main method, also attached to material forming engineering.
Stamping parts dies used in stamping parts dies is called, called dies. Die is the material (metal or non-metallic) into the batch processing of the special tools required for stamping parts. Is crucial in stamping parts die, do not meet the requirements of the die, batch stamping on difficult; not advanced die, advanced stamping process can not be achieved. Stamping process and die, stamping equipment and stamping parts materials constitute the three elements, only that they be combined in order to obtain stamping parts.
Pressing the production of efficient and easy to operate, easy to mechanization and automation. This is because the stamping parts dies and stamping parts equipment, rely on to complete the processing, general stamping parts trips up dozens of times per minute, high pressure to reach hundreds of times per minute, or even a thousand times over, each time stamping parts trip on may get a red piece.
Since the time stamping parts die stamping parts ensure accuracy of the size and shape, and generally do not damage the surface quality of stamping, but generally longer die life, so pressing the stable quality, good interchangeability, with "identical" characteristics. Press can process a larger size range, the shape of more complex parts, such as small to watch the stopwatch, large car rail, panel, etc., plus cold-pressing deformation of material hardening effect, punching strength and stiffness than those high. Stamping generally do not chip scrap generated, less consumption of materials, and without other heating equipment, which is a material saving, energy-efficient processing methods, the lower the cost of stamping parts.
However, stamping parts dies used in general has a special nature, and sometimes a complex part processing can take several sets of mold forming, and mold manufacturing high precision and high technical requirement, is a technology-intensive products. Therefore, only in stamping parts production volume is large enough, stamping parts the advantage to realize the full processing to obtain better economic benefit.
Of course, the stamping parts process has some problems and shortcomings. Mainly in the stamping parts process noise and vibration generated when two kinds of pollution, and operator safety incidents occur. However, these problems are not entirely due to stamping process and die to bring their own, but mainly due to the traditional stamping equipment and outdated manual result.
