基于DYNAFORM的电器支架翻边工艺优化分析

Analysis and Optimization of Electrical Support Flanging Process Based on DYNAFORM

继电器用支架结构简单,但纯铜材料价格较贵,需要在生产的各个阶段都节省原材料。制件采用级进模生产,错位双排,以满足大批量生产及提高材料利用率。利用DYNAFORM软件对翻边工序进行模拟,采用正交实验找出最优参数组合。模拟结果表明,预制孔直径为Ф1.6,模具单边间隙为0.8,压边力在4000~5000N之间是较为合适的工艺参数,模拟结果为实际生产的模具设计及工艺设计提供了有价值的参考。

The structure of the relay support was simple,but the price of pure copper material was expensive,so it was necessary to save raw materials at all stages of production.The part was manufactured by progressive die,blank layout was double row and dislocation,to meet mass production and improve material utilization.DYNAFORM was used to simulate the flanging process and orthogonal experiment was used to find out the optimal parameter combination.The simulation result shows that the diameter of the prefabricated hole wasФ1.6,the single side clearance of the die was 0.8,and the blank holder force was 4000~5000N,which provided a valuable reference for die design and process design.
