摘　　要：精度不稳定是平板类冲压件常见问题。本文从成型方案、回弹解决、模具结构设计、现场调试4个方面进行剖析。通过使用拉延成型代替压型,解决成型过程起皱问题。制定回弹解决方案时,优先采用调整拉延筋、增加余肉等方法,减小制件回弹。模具结构设计时,重点考虑制件定位和托起的稳定性。现场调试优先通过整形,提升制件精度。Accuracy instability is a common problem of simple-shaped panels.This paper provides solutions from four aspects:forming strategy,springback solutions,structural design,die debugging process.In order to solve the wrinkle,draw process is recommended to replace crash operation.When formulating the springback solution,it is preferred to adjust the drawbead and addendum to reduce the amount of springback.Part location and lifting stability should be paid great attention in structural design.Restrike is the first choice to improve the accuracy of product in the debugging process.
