Description

[0002] Copper busbar refers to the copper or aluminum busbar that connects the main switch in the power cabinet and the switches in each branch circuit in the power supply system. The surface is insulated and its main function is to be used as a conductor. In the production of copper busbars, since some copper busbars need to be routed in the distribution cabinet at different angles, the copper busbars need to be bent at different angles.

[0003] The copper bar bending machine is a kind of bending machine used for various types of copper or aluminum copper bars, so that the copper bars are bent into different states, which is convenient for the actual installation of the copper bars. When the existing copper bar bending machine bends the copper bar, in the process of adjusting the position of the copper bar, because the copper bar is in the shape of a flat plate, it is not easy to operate when the existing equipment or manual work needs to fix the copper bar, especially the existing equipment has a relatively single and traditional positioning method for the copper bar. Because the copper bar needs to be bent, the existing positioning structure and method have poor coordination with the bending action of the copper bar, making it difficult to ensure high-quality and efficient operation of the copper bar bending process. In many cases, it still relies on manual participation for assistance, which is difficult to achieve high automation and affects the bending efficiency of the copper bar. Summary of the invention
