In addition, the current terminal bending operation adopts manual bending or the revolving cylinder to match the bending knife to bend, and because of the characteristics of the manual and revolving cylinders, the precision of the control torque of the terminal bending operation cannot be well ensured, therefore, the bending angle of the terminal cannot be accurately controlled, thereby causing higher defective rate of the bent terminal, not only affecting the production efficiency, but also increasing the production cost.
In the terminal production line of some factories, the terminals are pressed and bent at one time by a pressing machine, so that the terminals with the same bending angle in the same batch can be obtained, and the reject ratio of products is reduced; however, the disposable bending has higher requirement on the toughness of the terminal, and if the toughness of the material of the terminal is insufficient, the terminal is easy to break when the pressing bending angle is slightly larger. And the terminal still needs to be cut and the like before being put into an injection molding machine for processing, but the existing terminal production line has low automation degree, and is difficult to realize better control on the efficiency and the reject ratio of equipment.
