The lower die reaches the upper limit, i.e., the bottom of the side die, under the force of the middle cam and the spring inside the lower die. The outer side of the bottom of the workpiece being drawn 104 is in contact with the lower die. The upper punch moves downwards to contact with the inner side of the bottom of the workpiece to be drawn, pushes the workpiece to be drawn and the lower punch to move downwards and completely pass through the side die, and then the drawing forming action is finished. After a distance is maintained, the upper die moves upward, and the lower die moves upward together with the drawing workpiece. After the lower punch die reaches a limit position, the drawing workpiece moves upwards along with the upper punch die continuously, the upper edge of the drawing workpiece is limited after reaching the demoulding mechanism and stops moving, at the moment, the upper punch die moves upwards continuously until reaching the upper punch die ascending limit, namely the lowest position of the cam, and at the moment, the drawing workpiece 101 is completely separated from the upper punch die. Under the action of the centrifugal force of the rotation of the rotating shaft assembly, the deep drawing formed workpiece 101 enters a corresponding notch on the discharging thumb wheel 102 to complete the discharging action.
