摘要
通过对侧壁带一小孔无凸缘一次拉深圆筒形件的工艺分析,合理设计了1副完成落料、拉深、侧冲孔3种工序的复合模,提高了产品质量、生产效率和经济效益。这种思路可以推广到侧面有多个孔盒形件的模具设计。
An analysis was made on the technique for drawing a flangeless cylinder component with a small side hole. Then a die combining blanking, drawing and side-punching process was develoPed for the forming. This method can also be used in the development of dies for box component with multi-side holes.
