摘　　要：白车身冲压件工艺设计阶段是材料利用率提升工作的重要阶段,从成形方式、工艺补充、料片形状、废料利用、减薄率检查5个方面详细地阐述了在工艺设计阶段材料利用率提升方法。特别是针对工艺补充方面,目前的研究相对较少,可以通过优化制件边界线与凸模圆角根距离、拉延管理面宽度、拉延分模线方法提升冲压件材料利用率,为材料利用率的提升工作提供了新思路与新途径。The process design stage for stampings of the Body In White(BIW)is an important stage to improve material utilization rate.This paper elaborated in details methods to improve material utilization rate in the process design stage from 5 aspects,i.e.forming method,process supplement,sheet shape,waste utilization,and thinning rate inspection.There are relatively few studies especially in process supplement.The material utilization rate of stamping parts can be improved by optimizing the distance between the workpiece boundary line and the root of the punch fillet,the width of the drawing management surface,and the drawing parting line,this provides new ideas and approaches for improving material utilization rate.
