某外壳零件成形工艺分析

Analysis of forming process for some outer covering components

针对底部带孔的有凸缘圆筒件成形工艺过程,确定了拉深工序的成形工艺参数,结合数值模拟方法模拟验证了拉深的成形过程。对冲孔成形工艺进行了模具设计,从而优化了工艺方案,对同类工件的成形工艺提供一定的借鉴,最终保证了圆筒件拉深成形工序的顺利进行。

Aimed at the forming process of flange cylinder with a hole in the bottom, the forming technological parameter of the drawing process was determined, and forming process was verified by combination of numerical simulation method. The die for the piercing process was designed and the technology scheme was optimized, which provides certain reference to the similar work piece＇s forming process. Finally the drawing process for the cylinder can be smoothly carried out.
