Abstract
According to the principle of the stamping die process, combining with the characteristics of product structure, adopt pound die blanking production and the structure of the elastic unloading, Design pound die verified by production practice, and its structure is simple and practical, stamping process is stable and reliable. Artifacts are analyzed in the design of the stamping manufacturability, calculated the blank layout, strong pressure and blade size calculation, etc. The mould general structure, design of ponents, draw the mold assembly drawing and parts drawing. Parts deep drawing process, with good performance after calculation can check once forming.
Parts deep drawing process with good performance, the calculation checking can be formed at a time.
Key words: posite modulus; The elastic unloading; Stamping, deep drawing technology; The mold design
