After the plc controller 17 receives the signal from the pressure sensor 19 and the staff presses the control switch 16, the plc controller 17 drives the cylinder 9 to operate through line control, actively moves in the direction of the tooling 4, and the working wedge 8 moves away from the first bending block 10. The first bending block 10 is located outside the pin 2. As the working wedge 8 moves The second bending block 11 (located on the inner side of the pin 2) cooperates with the first bending block 10 to perform the first bending on the pin 2. After the first bending, the pin 2 enters the guide groove 12 on the active inclined wedge 7 and performs the second bending. After the active inclined wedge 7 moves to the set position, the PLC controller 17 drives the cylinder 9 to drive the active inclined wedge 7 to move away from the tooling 4, the working inclined wedge 8 moves toward the direction of the first bending block 10, the pressure rod 6 moves toward the direction of the first bending block 10, and the T-shaped block 21 squeezes the end of the pin 2 to complete the bending.
