摘　　要：根据某零件宽凸缘深拉深成形工艺中存在的缺陷,对拉深过程中影响零件壁厚差的主要因素进行了分析,找出了缩小相对变形的依据。介绍了凸模浮动拉深成形工艺,综述了浮动凸模的设计要点、模具结构、工作原理及实际应用效果。Based on flaws in the deep drawing for a part with wide flange the main factors influencing the thickness variation of a part in drawing are analysed, the basis to reduce relative forming is found. The drawing technology by floating punch is introduced, including design points of floating punch, die structure, working mechanism and effect of practical use.
