Abstract：

Huge residual stress leads to stress corrosion cracking of the cylindrical drawing cups easily. The influences of die parameters (Die corner radius and punch-die clearance) on the residual stress of stainless steel 304 cylindrical drawing parts were investigated by seven sets of split-ring experiments and numerical simulations. The opening distances of rings were measured，the residual stresses were calculated by FEM numerical simulations of software ABAQUS. The results show that the circumferential residual stress increases firstly with the increase of the drawing punch-die clearance, then almost keeps constant when the clearance is bigger than 1.06t. The die corner radius is not affected by the circumferential residual stress. Radial residual stress in the middle of thickness increases with the increase of the drawing punch-die clearance and the die corner radius. As a result, a smaller punch-die clearance is more effective to reduce the residual stress in the wall of stainless steel 304 cylindrical drawing cups.
