2020-06-16 17:07:08

Automotive stamping parts, as the name implies, is composed of automotive parts of the metal stamping parts. In automobile stamping parts, some of them become automobile parts directly after stamping, and some of them become automobile parts after stamping by welding, or mechanical processing, or paint and other processes. There are many kinds of automobile stamping parts, such as car shock absorber stamping parts spring tray, spring seat, spring bracket, end cover, sealing cover, compression valve cover, compression valve cover, oil seal seat, bottom cover, dust cover, impeller, oil cylinder, supporting ear, bracket, etc. are all automotive stamping parts. The cold stamping of stamping parts, from a professional point of view, it refers to the use of press on the die, to exert a certain pressure on the material, make it separate or plastic deformation, thus, to obtain the desired finished product. And Punching and bending these two processes, generally speaking, is the first punch after bending, in order to carry out the processing of CNC punch. However, in some special cases, it is necessary to bend before punching. Stamping, if it uses hot stamping forming, then, in the specific process, mainly there are the following, is: Blanking: that is, the plate into the required outline of blank, for subsequent processing. AUSTENITIZING: It is included in the heating and heat preservation of the two stages. The processing aim is to heat the material to a suitable temperature so that it has good plasticity. Transfer: the heated material is removed from the furnace and fed into a hot-forming die.

Its key point, is the speed to be fast, if the speed is too slow, it will affect the quality of the stamping products. Stamping, quenching and subsequent treatment: is the material stamping molding, at a certain temperature, so as not to affect the material forming properties. When the material is formed, the mold must be closed and pressed for a certain period of time in order to allow the material to have good properties, at the same time, it must be quenched. And in the follow-up treatment, mainly some surface treatment, or drilling and other small processing.
