[0002] The stamping process is a processing method that applies load to sheet metal through designated stamping equipment and dies to cause it to undergo plastic deformation or separation, thereby obtaining a structural part of the desired shape and size. The stamping process is usually carried out at room temperature and is also known as cold stamping. It uses a die installed on a press to apply pressure to the material to cause it to separate or deform, thereby obtaining the desired parts. The objects of the stamping process are generally metal sheets or strips, thin-walled tubes, thin profiles, etc. One of the basic processes is blanking, which is a stamping process for separating sheet metal, including cutting, blanking, punching, notching, grooving, etc. Automatic feeding machinery and equipment include a feeding device, a positioning device, a transmission device, and a control device.
