Technical Field

[0001] The utility model relates to the technical field of laminated busbar production, and more specifically, to a laminated busbar V-shaped local hot pressing repair device. Background Art

[0002] Laminated busbar, also known as laminated busbar, composite copper busbar, is a multi-layer composite structure connection bar, which can be regarded as the highway of the power distribution system. Compared with the traditional, bulky, time-consuming and troublesome wiring method, the use of composite busbar can provide a modern, easy to design, fast to install and clearly structured distribution system. It is a high-power modular connection structure component with repeatable electrical performance, low impedance, anti-interference, good reliability, space saving, simple and quick assembly, etc.

[0003] At present, in the production process of laminated busbars, the insulating film on the surface of the busbar may not be completely compacted during the hot pressing stage due to various reasons, and blistering and wrinkling may occur in the subsequent bending operation, seriously affecting the product quality and safety. Since the shape of the busbar changes after bending, the busbar can no longer be re-hot-pressed using the previous hot pressing mold. The traditional treatment method is often to scrap it, which not only wastes resources, but also significantly increases the production cost of the enterprise. Utility Model Content
