Automotive stampings, as the name suggests, are metal stampings that makeup auto parts. Among auto stamping parts, some parts become auto parts directly after stamping, and the other parts need to be welded, machined, or painted before they can become auto parts after stamping.
There are many kinds of automobile stamping parts, such as automobile shock absorber stamping parts spring tray, spring seat, spring bracket, end cover, cover, compression valve cover, compression valve sleeve, oil seal seat, bottom cover, dust cover, impeller, oil Barrels, lugs, brackets, etc. all belong to automotive stampings.
Stamping is mainly classified according to the process, which can be divided into two categories: the separation process and forming process. The separation process is also called punching, and its purpose is to separate the medium-pressure parts from the sheet along a certain contour line while ensuring the quality requirements of the separation section.
The purpose of the forming process is to make the sheet plastically deform without breaking the billet to make a workpiece of the desired shape and size. In actual production, multiple processes are often applied comprehensively to one workpiece. Punching, bending, shearing, deep drawing, bulging, spinning, and straightening are the main stamping processes
Due to the different shapes, sizes, and precision of the workpiece, the stamping process adopts different processes.
