Forming principle of stamping parts: stamping is a forming processing
method for sheet, strip, pipe and profile by applying external force by
press and die to produce plastic deformation or separation, so as to
obtain the required shape and size of the workpiece (stamping part).
Process classification: stamping is mainly classified by process, which
can be divided into separation process and forming process.
Separation process (blanking process): its purpose is to separate the
stamping parts from the sheet along a certain contour line, and ensure
the quality requirements of the separation section. Separation process:
blanking (blanking, punching), cutting, cutting, edge cutting, cutting.
Deformation process of sheet metal during blanking
