Problems solved by technology

[0002] In the production of cables, in order to obtain better mechanical properties of the cables, it is often necessary to anneal the copper core wires used for the preparation of cables, so as to realize the adjustment of stress release and internal structure restructuring of the copper core wires. In order to improve the structural strength of the copper core wire, the current common method of annealing the copper core wire is to use special annealing equipment. Although the current annealing equipment can meet the needs of the annealing operation, due to At present, the annealing equipment has poor flexibility in adjusting its own structure, so it cannot effectively meet the needs of secondary heating annealing and continuous annealing operations at the same time. Therefore, the current annealing process of copper core wires is complicated, the production efficiency is low, and the production cost is high. The utilization rate and adaptability of the copper core wire are relatively poor, and it cannot effectively meet the needs of the current copper core wire annealing processing. In view of this problem, it is urgent to develop a new copper core wire annealing equipment and its matching annealing process. Meet the needs of actual use
