回弹是板料冲压成形中的主要缺陷之一 ,控制回弹涉及到回弹量的准确预算。利用DANAFORM软件 ,对U形件拉深成形回弹影响因素进行了计算机仿真 ,得到了压边力、凸凹模间隙、摩擦系数、材料特性等参数对回弹影响的数值结果 ,并对模拟结果进行了分析。
Rebounding is one of the major drawbacks in sheet metal stamping and the control of rebound involves an accurate estimate of rebound volume. Using DANAFORM software, the influencing factors of springback of U-shaped deep drawing forming were simulated by computer. The numerical results of the influence of blank holder force, punch and die gap, friction coefficient and material property on springback were obtained. And the simulation results were carried out Analysis.
