The upper die base 10 is slidably supported on the lower die base 11 by a plurality of guide rods penetrating the upper die base 10.

[0035] Working principle of this utility model:

[0036] Through the above arrangement, the upper die of the utility model is mainly composed of a nitrogen spring, an upper die fixing plate 2, a punching punch 3, an upper punch connecting plate 4, a trimming die 5, an upper punch 6 and an upper die seat 10, and its main function is to cut off the flash and flush out the skin. The lower die is mainly composed of a lower punch 7, a lower top flash plate 8, a lower punch connecting plate 9 and a lower die seat 11, and its main function is to position and top the flash.

[0037] The trimming function mainly utilizes the relative movement of the trimming die 5 and the lower punch 7 to cut off the flash of the workpiece. The punching function utilizes the relative movement of the punching punch 3 and the lower punch 7 to punch out the punching skin. The correction function mainly utilizes the upper punch 6 and the lower punch 7 to perform correction after closing.

[0038] First, the forged workpiece is placed on the lower punch 7 for positioning. As the equipment moves, the nitrogen spring 1 of the upper die, the upper die fixing plate 2, the punching punch 3, the upper punch connecting plate 4, the trimming die 5, the upper punch 6, and the upper die seat 10 are driven downward. The trimming die 5 contacts the flash part of the workpiece, cuts off the flash, and continues to move downward. The punching punch 3 begins to punch out the skin of the hole and continues to move downward to reach the bottom dead point. The upper punch 6 and the lower punch 7 hold the workpiece for correction. The equipment starts to drive the upper die to move upward, and the upper and lower dies are separated. The nitrogen spring 1 pushes the lower top flash plate 8 to lift the cut flash so that the flash can be grabbed and removed. The whole action process is completed.
