| 摘 要： | 运用Dynaform软件建立高强钢板DP590的U形件有限元模型,进行了恒定压变力、恒定冲压速度条件下的回弹预测,并通过相同条件下的实验验证了回弹预测的准确性。为实现高强钢精密冲压件回弹的智能控制,进行了变冲压速度和变压边力条件下的U形件的拉深试验。其试验结果表明,采用变压力技术比变冲压速度技术更能有效地控制高强钢精密冲压件的回弹。

| Abstract: | A finite element model ( FEM) is established for predicting high strength steel DP 590 springback of U-shaped part under constant blank holder force and constant stamping speed with using Dynaform software .The experiments were carried out to vali-date the simulation predictions .In order to realize intelligent control of high strength steel precision stamping part 's springback , the U-shaped part drawing experiments were carried out under variable blank holder force and variable stamping speed .The results of experi-ments show that the springback is smaller when the experiments with effective control of the variable blank holder force . |
