摘　　要：板料拉深过程中，压边力是一种重要的工艺参数。由于其在冲压拉深过程中的重要作用及在生产中易于调节、控制，近年来一些汽车工业较为发达的国家，正在进行着变压边力拉深新工艺方法的研究。本文从板料冲压拉深过程对压边力需求的分析中，提出了变压边力控制方法的原理，建立了变压边力拉深实验系统，并以圆锥形件为研究对象对拉深过程中合理的变压边力控制问题进行了探索性研究，取得了阶段性成果。Blank holding force is an important technical parameter while sheet metal is deep drawnBecause it is easily adjusted and controlled during deep drawing,some developed countries in automobile industry are researching a new technological method of the variable blank holding force for deep drawing in recent yearsThough an analysis of the requirements for the deep drawing process of sheet metal,this paper puts forward the controlling principle of the variable blank holding force and sets up the deep drawing experimental systemFor the basis of conical parts,some researches have been carried out on the reasonable variable blank holding force and some tentative results obtained during deep drawing
