Abstract：

Crack easily occurs in secondary flange holes of fins in the punch stroke due to the reductive thickness of aluminum in the production of heat exchanger fins for air-conditioning, which seriously weakens the production efficiency and quality of fins. Based on response surface method (RSM), the multi-response model between the punch stroke of five drawing steps and the thinning rate of the fin was established, and the interaction effect between the different steps was analyzed. Then, on this basis, the response surface method was optimized by the satisfactory function method, and the optimal combination of the five step′s stroke parameters settings was obtained. The FEA and the production experiment results show that after optimization, the maximum thinning rate of the flange hole decreases by 5.5%, and the forming quality of flange holes is significantly improved to reach the expected goal.
