Abstract：

Defects such as cracks and wrinkling occur easily in the forming of conditioner heat exchanger fin due to the over thin of wall thickness. The traditional solutions are the simple analysis and tests repeatedly. In this essay, the material flow and the stress distributions in the process of forming were obtained by numerical simulation, which provided enough support for the process design and die structure optimization. The heat exchanger fin used in the air conditioner was taking as the research object，the multi-step drawing processes in the progressive stamping process were simulated by the Dynaform software. The defective areas of wrinkling and cracking during multi-step drawing were predicted, and the prevention methods of the cracks were further researched. The results show that the bigger fillet radius of the punch and die has significant effects on preventing the crack.
