It is difficult to make the wire bending die at one time to ensure the angle, and it is difficult to calculate the springback. Before, we could only roughly calculate the angle and then repair the die while pressing, and sometimes we can control the springback by adjusting the pressure of the punch. Moreover, after adjusting the required angle, the springback will change after slightly replacing different batches of materials. It is suggested that the shaping process should be added to such fine wire.
