摘要:

由于生产空调换热器翅片的铝箔厚度的减薄,翅片在多工位级进模冲压成形过程中容易出现二次翻边孔开裂的问题,严重影响了翅片的加工效率和产品质量。基于响应面法,建立了鼓包拉深工序中5个工步的凸模冲程对翅片减薄率的响应面模型,分析了不同工步冲程之间的相互作用。并在此基础上,采用满意度函数法对所建立的响应面进行优化,获得了鼓包拉深工序中5个工步冲程参数设置的最优组合。仿真实验及生产实验结果均显示:优化后翅片的翻边孔的最大减薄率减少了5.5%,成形质量明显提高,达到了预期的优化效果。
 

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.
