冲压工艺参数对回弹的影响及改进方法比较

Stamping Process Parameters are for the Influence of the Springback and Improvement Method

板料成形都存在回弹,因回弹使得板料零件无法满足使用要求。论文围绕实际工件回弹的情况,通过有限元CAE方法,探讨了预成形压力、摩擦系数、间隙等主要因素对回弹的影响,并提出了减小回弹的几种方法,经实际验证效果良好。

There are the spfingback during metal sheet forming, so metal sheet parts can not meet the requirements. This paper focusing on the case of the actual workpiece springback, through the finite element CAE methods, discusses the force before forming, coefficient of friction, clearance and other main factors on the springback effect, and puts forward several methods of reducing the springback. The effect is good that verified by the practice.
