碗脚落料拉深冲孔复合模设计

Design of Compound Die for Blanking and Piercing of Bowl Foot

针对碗脚的结构特征进行冲压工艺分析,采用落料、拉深、冲孔复合模结构并选择在普通开式压力机上一次冲压成形,既保证了制件的尺寸精度要求,又提高了生产率,克服了原来采用落料、拉深、冲孔单工序模生产的制件质量差和生产效率低等缺点,同时为同类制件的模具设计提供了参考。

Aiming at the structure characteristics of bowl foot stamping process analysis, the blanking drawing punching compound die structure and selection in general open press time stamping, ensure the dimensional accu- racy of the workpiece, and increase productivity, provide a reference for the design of similar parts of the mold.
