摘要：
|
|
分析了某轿车后灯座的工艺特点,制定了不同的工艺补充面模型,首先采用板料三维成形分析软件DY-NAFORM对其坯料形状进行优化;然后,根据模拟结果,选取两种不同形状的坯料,对该零件的拉深成形工序再次进行数值模拟仿真分析,通过对其FLD图和成形结果的分析、比较,优化了工艺型面,得到了合理的拉深凹模型面,最终生产出合格产品。

The processing characteristics of a vehicle lamp holder were analyzed,and different craft supplement face mold was worked out.First of all,the three-dimensional sheet metal forming analysis software DYNAFORM was adopted to simulate the size of blank;and then,according to the simulation results,two different programs of blank shape were selected to simulate lamp holder's drawing process again.The surface of die was optimized through analyzing the FLD diagram and the forming result.Finally a reasonable drawing die mold was decided.And the perfect products were already manufactured.
