Stamping process
Stamping is mainly classified according to the process, which can be divided into two categories: separation process and forming process. The separation process is also called blanking, and its purpose is to separate the stamping parts from the sheet along a certain contour line, while ensuring the quality requirements of the separation section (Table 1). The purpose of the forming process is to plastically deform the sheet without breaking the blank to make a workpiece of the desired shape and size. In actual production, multiple processes are often grated into a workpiece. Blanking, bending, shearing, deep drawing, bulging, spinning, and straightening are several main stamping processes.
