The flexible half-hoop automatically supports the copper busbar, and through the flexible deformation effect of the flexible half-hoop, when the flexible half-hoop touches the copper busbars of different diameters, it can be deformed, thereby supporting the copper busbars of different diameters, thereby improving the applicability of the device. The sliding rod drives the flexible half-hoops to move away from each other, preventing the copper busbar with a larger diameter from being blocked by the flexible half-hoop during the movement to the right.

[0010] 3. The bending device for copper busbar production sprays the internal stretching oil onto the surface of the copper busbar after the elastic liquid storage bag is pressurized, thereby reducing the grinding generated during the bending process of the copper busbar, reducing metal fatigue, and improving the processing quality of the copper busbar.
