How is the blanking sequence arranged in the processing of metal stamping parts?

With the development of society, stamping products have developed into various fields. In the processing of metal stamping parts, the workpiece must be stamped and cut. What is the order of stamping and cutting? Let's take a look at it below. Use the progressive die blanking sequence arrangement to punch holes or notches first, then blank or cut, to separate the blanking piece from the strip. The first punched hole can be used as a positioning hole for the subsequent process. When the positioning requirements are high, the craft holes (usually two) dedicated to positioning can be punched. When the fixed-pitch side edge is used, the trimming process of the fixed-pitch side edge is arranged at the same time as the first punching, so as to control the feeding distance. When two fixed-pitch side edges are used, they can be arranged one after the other or side by side; multi-process blanking parts are arranged in a single-process blanking order when the blanks are first blanked, and then punched or notched. Then continue the positioning of the process, and the reference should be consistent to avoid positioning errors and dimensional chain conversion. When punching holes of different sizes and close to each other, in order to reduce the deformation of the holes, the large holes should be punched first and then the small holes. After the process plan is determined, necessary process calculations and selected equipment are required to provide the necessary basis for mold design.
