On the basis of process analysis, the yield and precision requirements of the product are comprehensively considered. The properties of the materials used, the technical strength of the factory, the equipment conditions and the mold manufacturing conditions determine the process specification of the workpiece and the die structure of each process. Structural design: On the basis of the scheme design, further design the specific structural dimensions of each part of the mold.

(1) Process analysis of blanking Analyze the structural shape, dimensional accuracy, whether the material meets the requirements of the stamping force, and determine the possibility of blanking.

(2) Determine the blanking process plan and mold structure The number of processes, the nature of the process, the sequence of processes, the combination of processes and the structure of the mold.
