目的：解决隔热板成形常见问题以及预测回弹量的大小。方法以有限元分析软件 Dynaform为基础,研究毛坯尺寸、压边力、拉延筋布置以及摩擦因数对隔热板成形性的影响。结果得出了隔热板的较佳成形工艺参数。结论通过修正模具和改善工艺来不断地改善回弹,能准确地预测回弹量的大小。优化后的回弹量分别为△d =0.918 mm,△α=0.340°,回弹量得到了有效的控制。

Objective To solve the forming flaws of thermal baffles and to predict the amount of spingback. Methods The effects of blank size, blank holding force, draw bead layout and friction coefficient on the forming quality were studied through simulation based on the finite element analysis software Dynaform. Results The optimal processing parameters of thermal baffle were obtained. Conclusion The size of the springback could be precisely predicted and the effect of spring-back could be improved through constant mold compensation and process improvement. The springback after optimization was △d=0. 918 mm and △α =0. 340°, respectively, and the springback could be effectively controlled.
