Description

Technical Field

[0001] The present invention relates to the technical field of stamping equipment, and in particular to an automated automobile parts stamping device and a stamping processing method. Background Art

[0002] Auto parts refer to the various components and assemblies that make up a car, covering the engine, chassis, body, electrical system and other parts.

[0003] At present, stamping is a production technology that uses the power of conventional or special stamping equipment to directly subject the sheet metal to deformation force in the mold and deform it, thereby obtaining product parts with certain shapes, sizes and performances. Sheet metal, mold and equipment are the three elements of stamping. Stamping is a metal cold deformation processing method. Therefore, it is called cold stamping or sheet metal stamping, or stamping for short. It is one of the main methods of metal plastic processing (or pressure processing) and also belongs to material forming engineering technology.
