摘要

摘要: 应用Dynaform仿真软件对金属板料进行了拉深过程的模拟分析,得到了压边力、拉深速度和摩擦系数对于拉深过程中板料成形速度的影响。板料成形速度决定拉深质量,在成形过程中压边力和拉深速度是可控参数,摩擦系数是在一定条件下可以干预控制的参数,同时是多参数共同作用的表现,对成形质量和模具寿命影响较大。影响摩擦系数的主要因素除材料外,还有压边力、拉深速度及润滑状态,成形速度是影响润滑状态的关键因素。

Abstract: A simulation for the deep drawing process of sheet metal was carried out by using Dynaform,the influ-ence of blank holder force,drawing speed and friction coefficient on the forming speed in the deep drawing process of sheet metal were obtained.The forming speed in the deep drawing process of sheet metal determines the form-ingquality of deep drawing,the blank holder force and the deep drawing speed in the deep drawing process are con-trollable parameters,the friction coefficient can be intervened and controlled,and it's a manifestation of the inter-action of all parameters,the main factors which influence the friction coefficient just have blank holder force,form-ing speed and lubrication except the material.
