Abstract：

In order to saving the materials and increasing the efficiency,the article have designed the transfer unit progressive die to replace the traditional progressive die during the CPU fin's stamping forming.For settling down the question of the waste scrap from the transfer unit progressive die during the trimming station,the article have given the design method of the die for the trimming station.The structure have resolved the question of the waste scrap,increased the velocity,saved the cost and gotten the more benefit.It has provided the experience for the designer.
