Abstract：

By the experiments,it is found that the lips are always taken place firstly at some dangerous areas during drawing,and however,the dangerous areas are due to the asymmetry of deforming.A new method that changes the flow tendency of metal by exerting forces initiatively to improve the efficiency of drawing is introduced.According to this new method,the die structure for cup drawing is provided,and the key points of design are also given.It is proved by practices that the die can improve the efficiency and quality of cup drawing
