Description

Technical Field

[0001] The utility model relates to the technical field of auxiliary tooling for manufacturing joints in a submarine cable factory, in particular to a straightening device for welding conductors of ultra-high voltage submarine cable factory joints. Background Art

[0002] In the process of making submarine cable factory joints, conductor welding is the first step in the production of factory joints. Since the production of factory joints can only be carried out sequentially, no step can go wrong during the process, and the quality of conductor welding directly affects the performance of factory joints, so the conductor welding process is particularly important. Before welding the factory joints, the conductor needs to be folded and polished, and welded from the inside to the outside in sequence. The folded conductor needs to be restored before welding. If manual welding is used directly, the huge weight of the submarine cable will make it very difficult to connect the conductors, and the operation is difficult. There is currently no public straightening device for factory joint welding, and the related cable conductor welding straightening device is relatively complicated, which is not convenient for the restoration of the conductor before factory joint welding.

[0003] In view of the above problems, it is necessary to provide a straightening device for welding conductors of ultra-high voltage submarine cable factory joints which has a simple structure and is easy to operate to solve the above problems. Utility Model Content
