[0002] Copper conductor is a term in electromechanical engineering, used for fire-resistant layer, insulation, sheath, and filling. The bundle twisting machine is a twisting device used in the wire harness industry. It rotates and interweaves two or more cables with the same wire diameter into a twisted pair or multiple twisted wires through a constant pulling force. Before the wire harness is twisted, the wire harness needs to be tightened before twisting; pulling the wire harness too tight or too loose will have a certain impact on the twisting of the wire harness.

[0003] In the process of copper conductor processing, a bundle twisting machine wire tension constant device is needed. In the process of processing, the wire harness in the prior art needs to twist multiple wires into a wire harness. The required tensioning force during the winding and releasing process of wire harnesses of different materials is different, and the tensioning force cannot be adjusted separately for wire harnesses of different materials, which causes inconvenience in use and affects the processing efficiency and the quality of the wire harness after twisting. At present, manual twisting is generally adopted. Therefore, the product is often difficult to operate manually, has low work efficiency, and uneven manual control, resulting in uneven twisting of some wires and uneven thickness of the wire harness, which seriously affects the production quality of the wire harness and cannot meet the production needs. Therefore, a bundle twisting machine wire tension constant device is proposed to solve the above problems. Utility Model Content
