摘　　要：通过对零件结构工艺性分析,制定了连续拉深的工艺方案。对毛坯尺寸、修边余量、拉深系数、各次拉深直径及拉深高度进行了设计,对工序排样进行了计算,并制定出工序排样方案,设计出拉深冲裁级进模的模具结构图。Through the structure analysis of parts technology, the continuous deep drawing process was established. The blank dimensions, trimming allowance, drawing coefficient, the drawing height and drawing diameter were designed. The process layout was calculated and constituted. The structure figure was designed for blanking deep drawing progressive die.
