摘　　要：通过对发电机定、转子冲片零件结构分析,提出预冲孔→单槽冲定子槽孔→定、转子复合冲裁方案,相对传统定、转子复合模方案,优化设计后的定、转子复合冲模方案将传统的开放式环形改为上半部封闭的结构,同时采用内圆有限刃口高度的实体整圆刃块形式的凸凹模,解决了制件冲压变形问题,减小了材料及降低了加工成本,提高模具成形制件质量和延长模具使用寿命。Based on the structure analysis of the stator and rotor stamping sheet, the scheme that pre-piercing, stator slot piercing with single slot, stator and rotor compound stamping was proposed. Compared to the traditional compound die, the optimization design of stamping compound die for stator and rotor changed the open ring to the upper semi-closed structure, and the punch-matrix with limited edge cutter height in the inner entity circle was adopted. It avoided the stamping deformation of parts and prolonged the service life of the die.
