摘　　要：回弹是冲压件成型过程中的主要缺陷之一,是冲压生产中较难解决的问题,也是实际工艺分析过程中很难克服的成型缺陷。它不仅降低了产品的品质,还制约了焊接匹配关系。文章主要介绍冲压产品借助AutoForm软件分析弥补工艺分析的不足,并且模拟分析回弹发生整个过程,测量回弹量,根据回弹量在模具设计给予回弹补偿,以实现回弹控制。Springback is one of the major defects in stamping process as well as a difficult problem in stamping production,and is also a deforming defect which is difficult to overcome in actual process.It not only decreases the product quality,but also restricts the weldmatching relationship.Bymeans ofAutoForm to analyze and make up for the process analysis lack of stamping products is introduced in this paper.And simulation analysis of rebound occurred throughout the process is carried out.Measuring springback,according to the amount springback compensation is given in die design and springback control is realized.
