| 摘 要： | 计算机仿真技术应用于汽车覆盖件冲压模具的设计开发中,在一定程度上满足了汽车覆盖件冲压成形精度要求。以汽车减震器后桥覆盖件为典型零件,通过Dynaform软件对该产品进行模拟。通过模拟结果,分析板料厚度和拉延筋高度的变化对产品拉裂缺陷的影响。选取优化后的工艺参数进行了仿真,并得到了较好的冲压成形质量。从而大大缩短模具设计开发周期,降低板料成本的目的。

| Abstract: | The Automoive Panel stamping die is use computcer simulation tecbnology to design,to a certain extent,to improve accuracy of the domestic automobile panelforming,It has with alautomobile shock absorber rear axle cover piece for type part,combine on dynaform software suffer,past analogue result,Board thickness and brake bead altitudinal change versus product quality impact.then select optimize rear processing parameter proceed know clearly emulation,combine got get know clearly best drawing quality fairing.Thus greatly shorten the mould design and development period,lower the cost of sheet metal purpose |
