Abstract: The influence of die parameters including the fillet radius of punch and die, gap between punch and die, half cone angle of ironing die on the multistep drawing process was studied by the finite element numerical simulation analysis.The results show that with the decrease of punch and die radius and die clearance, the dangerous area of drawing parts will become thinner obviously. The metal flow is more smooth when the half cone angle of ironing die is 20°-25°.
