摘　　要：研究了波纹板的冲压成形工艺及其回弹控制方法。首先对波纹板进行工艺分析并建立其有限元模型,然后依据仿真结果完成模具结构设计,最后以回弹角为评价指标,基于正交试验研究了冲压速度、摩擦因数和凸模圆角半径等工艺参数对波纹板回弹的影响。极差分析发现,各因素对回弹的影响顺序为:凸模圆角半径>冲压速度>摩擦因数。最终确定最佳的工艺参数组合为:凸模圆角半径为1.8 mm,冲压速度为4 m·s-1,摩擦因数为0.13。通过伺服冲压试验发现,波纹板的回弹角由2.64°降低至1.53°。研究结果表明,所采用的波纹板的成形工艺正确,模具结构设计合理,并且通过工艺参数优化可以有效降低波纹板的回弹。The stamping process of corrugated plate and its springback control method were studied.Firstly,the process analysis of corrugated plate was carried out and its finite element model was established,and then the die structure was designed according to the simulation results.Finally,taking the springback angle as the evaluation index,based on orthogonal test,the influences of process parameters such as stamping speed,friction factor and punch fillet radius on the springback of corrugated plate were studied.The range analysis finds that the influencing order of various factors to the springback is as follows:punch fillet radius>stamping speed>friction factor.The best combination of process parameters is the punch fillet radius of 1.8 mm,the stamping speed of 4 mm·s-1 and the friction factor of 0.13.Through servo stamping test,it is found that the springback angle of corrugated plate is reduced from 2.64°to 1.53°.The results show that the used forming process analysis of corrugated plate is correct,the die structure design is reasonable,and the springback of corrugated plate is effectively reduced by optimizing the process parameters.
