摘要：

Cracks frequently occur in conventional cylindrical deep drawing process due to the lower formability of aluminum alloy sheet at room temperature. Therefore, a new approach named electromagnetic pulse assisted progressive deep drawing is proposed in this paper. This method gains the radial electromagnetic force which helps to push the sheet metal in radial direction by placing the circular thrust coil upon and underneath the flange, while gaining the axial electromagnetic force by placing drawing coil in the bottom of the punch. The results shows that the placement of the radial thrust coil has significant effect on the sheet metal's state and distribution of stress-strain; In addition, the interaction of the axial drawing force and the radial thrusting force has great effect on the depth of the deep drawing cylindrical parts.
