Abstract：

It is discussed in this Paper the space equal paranieter element is suitable for the stress analysis of cold forming dies as compared with lem'e solutions, The law of stress distribution of circle die insert that varies with pressure area height is obtained·T he influence of stress concentration and shriking on allowance on stress distribution of cold forming die is anatysised by caculating the stress of the sixangle die insert in actul working conditon It is important to supply a method and reference for design of cold forming die.
