Article Preview

According to the shape character of some one automobile inner panel of front fender the forming steps characterized by some process combined was brought forward. Based on FEM software the drawing process was simulated by a blank-holder force scheme 100000N, 200000N, 300000N. As the simulation results, in order to eliminate the fractures in diagonal reinforcements, it is infeasible only to decrease blank-holder force, but enlarging the die round corner is necessary. As fractures have been eliminated, in order to eliminate wrinkles, the blank-holder force needs to be increased. Otherwise the wrinkle region can be confined into useless area which needs to be cut off. Finally none forming defects occur as blank-holder force 300000N and die round corner 5mm.
