In the prior art, the multi-station progressive die moves at a relatively stable speed, and the movement of the die cannot be interfered by the die before moving to the next station and being ready for stamping. In the process of forming symmetrical bidirectional bending, particularly when the surface of the folded edge formed by bending and the contact surface of the die are not parallel to the movement direction of the workpiece, and the folded edge is formed into a negative angle, the die is very inconvenient to separate. Since the surface of the flange, which is in contact with the die, is not parallel to the direction of movement of the workpiece, the workpiece cannot be pulled out in the direction of movement of the workpiece. Since the shaping effect of the workpiece requires a workpiece with a bi-directional negative angle fold, the workpiece cannot be pulled out in a direction perpendicular to the plane of motion of the workpiece. In this case, with the conventional die, the workpiece cannot continue to move after being press-formed, which is disadvantageous in realizing rapid production.
