中文摘要：宽凸缘筒形件在冲压成形中金属流动复杂，板料变形困难，容易出现起皱和拉裂。以宽凸缘拉深件为研究对象，设计了一副带压边圈的反拉深模具结构，并对该模具在成形过程中工件产生的质量问题进行了分析，最终获得了合格工件。
英文摘要： The metal flow of cylinder with wide flange is complex in punching process, the deformation of sheet metal is difficult, it is easy to present wrinkle and crack. Taking drawing cylinder parts with wide flange as research object, a set of inverse drawing die with binder was designed, and the forming defects were analyzed, the qualified parts were gained.
