An upper pressing part 12 is provided, and the upper pressing part 12 is arranged opposite to the lower supporting part 9 to form a cutting station. A cutter is provided on one side of the upper pressing part 12, and the movable plate 5 is provided with a clearance hole 13. The U-shaped seat 10 and the rotating shaft of the movable plate 5 pass through the clearance hole 13. Therefore, when the piston rod of the second cylinder 3 is extended, the front end of the movable plate 5 can be lifted, and when the piston rod of the second cylinder 3 is retracted, the cutter at the front end of the movable plate 5 can quickly cut down to complete the cutting of the wire, thereby completing the cutting and forming of the connecting shaft 1 at the cutting station. When the cutting is completed, the piston rod of the first cylinder 2 is extended to make the lifting plate 7 move down as a whole to the loading station of the pressing position to wait for assembly. This structure realizes precise control of the cutting operation, improves the cutting accuracy and operation flexibility, ensures the stability and reliability of the cutting action, and can complete the subsequent automatic transfer at the same time, realizing a high degree of automation.
