摘　　要：针对盒型拉深件在拉深中出现的零件起皱问题,采用正交试验方法研究凸凹模间隙、压边力、摩擦因数和冲压速度这4个因素对零件起皱的影响。利用Dynaform软件对试验进行模拟仿真,考察最大增厚率与这4个因素之间的关系,得到的成形该零件的最佳工艺参数为:凸凹模间隙1 mm、摩擦因数0.15、压边力60 kN、冲压速度6000 mm/s。根据所得到的优化参数改进了模具结构,从而解决了零件的起皱问题。In order to solve the wrinkling problem of box drawing parts in deep drawing,the orthogonal test method was used to study the influence of four factors on wrinkling,such as punch and die clearance,blank holder force,friction factor and stamping speed.The Dynaform software was used to simulate the test,and the relationship between the maximum thickening rate and the four factors was investigated.The optimal process parameters for forming the part were obtained as follows:punch and die clearance 1 mm,friction factor 0.15,blank holder force 60 kN,and stamping speed 6000 mm/s.According to the optimized parameters,the die structure was improved,and the wrinkling problem of the part was solved.
