A dry structure of copper wire after annealing and cooling treatment

Abstract

The invention discloses a drying structure for a copper wire subjected to annealing cooling treatment. The drying structure comprises a box body, multiple through holes are formed in the upper portion of the box body, the box body is filled with a sponge block, the upper surface of the sponge block penetrates through the through holes and protrudes outwards to form absorption parts, multiple sieve plates used for wrapping and covering the absorption parts are arranged on the box body, and dehumidification cloth sticks to the upper surfaces of the sieve plates. Due to the fact that the dehumidification cloth sticking to the sieve plates makes contact with the copper wire, cooling water on the outer wall of the copper wire is absorbed by the dehumidification cloth, the cooling water accumulated on the dehumidification cloth is absorbed by the sponge block through sieve meshes formed in the sieve plates, that is, it can be guaranteed that the water content of the dehumidification cloth itself is in a low level in the long-term using process of the dehumidification cloth by means of the sponge block, the situation that secondary water attaching occurs on the outer wall of the copper wire is avoided, and the performance of the copper wire subjected to annealing cooling treatment is guaranteed; meanwhile, repeated and uninterrupted dehumidification cloth replacing is avoided, and the use cost is reduced.

Description

technical field [0001] The invention relates to the field of copper stranded wire processing, in particular to a dry structure of copper wire after annealing and cooling treatment. Background technique [0002] During the production and processing of copper wire, when the copper wire is pulled, stretched, twisted and wound, stress will be generated inside it, and it will become hard or even oxidized locally, so this kind of crude product cannot be further processed into copper soft stranded wire. Therefore, the copper stranded wire must be annealed. The general treatment method is to use nitrogen as a protective gas and anneal in the annealing furnace. First, the air is extracted from the annealing furnace to form a negative pressure to a certain extent and then filled with nitrogen. The pressure is formed inside, and when it is heated to about 300 degrees Celsius, it is kept for one end of time, and then the furnace is turned on to cool naturally. However, after this kind ...

AI Technical Summary

Problems solved by technology

Traditional annealing cooling uses tap water quality and natural cooling precipitation, and there will be some moisture residue on the surface of the copper wire. Through transmission and transfer, the surface of the copper wire will be partially oxidized, which will affect the performance of the copper wire.
