摘　　要：介绍了筒形类零件的落料、拉伸、切边复合模 ,该模具采用特殊压边结构使压边力随拉伸行程的增加而增大 ,当达到最大值后又逐渐减小 ,以符合拉伸变形规律 ,并且该模具在拉伸结束的同时进行切边 ,减少了工序 。The blanking, drawing and trimming compound die for canister_shaped parts was introduced. A special blank_holding structure was adopted to the die so that the blank_holding force increases with the forwarding of the drawing stroke and decreases after reaches the maximum value, so as to accord to the rule of the drawing deformation. The die makes the trimming process after drawing. It reduced the operation procedure and increased the production efficiency.
