The nature of metal stamping parts What?


Metal stamping parts processing is powered by means of conventional or special stamping equipment, stamping the plate material in the mold directly affected by the deformation force and the deformation, so as to obtain a certain shape, size and performance of the product parts production technology. Sheet metal, tooling and equipment are the three elements of stamping. Is a metal stamping cold deformation processing methods. So called cold stamping or sheet metal stamping, stamping short. It is one of metal plastic processing (or pressure processing) of the main methods are also attached to the molding material engineering technology.
Die stamping molding used called stamping dies, referred to die. Die is a material (metal or nonmetal) batch processing into special tools required for stamping. Stamping die stamping parts production is crucial, did not meet the requirements of the die, stamping parts production batch will be difficult to carry out; no advanced die, advanced stamping process can not be achieved. Stamping process with metal stamping die, stamping equipment and stamping the three elements of material stamping, only they combined with each other in order to obtain stampings.
Compared with other methods of mechanical processing and plastic processing, punching both in technical and economic terms has many unique advantages. Mainly as follows.
High (1) stamping parts processing productivity, and easy to operate, easy to implement mechanization and automation. This is because the stamping is to rely on stamping dies and stamping equipment to complete the process, the general press trips per minute up to dozens of times, pressure to speed up even more than several hundred thousand times per minute, and each stamping stroke might get a stamping.
(2) Since when stamping stamping die to ensure that the size and shape precision stampings, and generally do not damage the surface quality of stamping, stamping dies and generally longer life expectancy, so the stable quality of stamping, good interchangeability , with "exactly the same" feature.
(3) stamping parts processing a large range of sizes, shapes more complex parts, such as small to watch the stopwatch, large car stringer, covering parts, plus stamping when cold deformation hardening effect of the material, strength and punching rigidity are high.
(4) stamping Usually no swarf SCRAP generate less material consumption, and does not require additional heating equipment, so it is a material saving, low cost energy-efficient processing methods, stamping.
Because of having such a superiority stamping, stamping parts processing in various fields of national economy wide range of applications. For example, in aerospace, aviation, military, machinery, agricultural machinery, electronics, information, railway, telecommunications, transportation, chemicals, medical equipment, household appliances and light industry sectors both in stamping parts processing. Not only have used it throughout the industry, and everyone direct contact with the stamping items occur. Like airplanes, trains, automobiles, tractors, there are many large, medium and small stampings. Car body, frame and rims and other parts are stamping out. According to the survey, bicycles, sewing machines, watches, there are 80% of stampings; televisions, tape recorders, video cameras, there are 90% of the stampings; metal shell as well as food, fine boiler steel, enamel pots and stainless steel tableware bowl, all using a stamping die stamping products; even the hardware in the computer also can not lack stampings.
However, stamping dies used in stamping generally have dedicated, and sometimes part of a complex process to take several sets of mold forming, and high precision mold manufacturing, high technical requirements, technology-intensive products. Therefore, only in stamping production volume is large, the advantages of the stamping process can be fully reflected, so as to obtain better economic benefit.
Of course, the stamping process there are still some problems and shortcomings. Mainly when punching noise and vibration produced by two kinds of pollution, but also occur when the operator's safety accidents. However, these problems are not entirely due to the stamping process and stamping mold itself brings, but mainly due to the traditional stamping equipment and backward and manual handling. With the progress of science and technology, especially the development of computer technology, with the progress of mechatronics technology, these problems will be solved as soon as two perfect.
