Copper wire outer wall drying treatment device

Abstract

The invention discloses a copper wire outer wall drying treatment device. The device comprises a box body. A plurality of 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 to extend outwards to form absorption parts. A plurality of screen plates used for wrapping and covering the absorption parts are arranged on the box body. Dehumidifying cloth is bonded to the upper surfaces of the screen plates. The dehumidifying cloth bonded to the screen plates is used for making contact with a copper wire, so that cooling water on the outer wall of the copper wire is absorbed by the dehumidifying cloth, and cooling water accumulated on the dehumidifying cloth is absorbed by the sponge block through screen meshes of the screen plates, that is, it can be ensured that the water content of the dehumidifying cloth is at a low level in the long-time using process of the dehumidifying cloth through the sponge block, and secondary attached water on the outer wall of the copper wire is avoided, so that the performance of the copper wire is ensured after annealing cooling treatment. Meanwhile, the dehumidifying cloth is prevented from being repeatedly and uninterruptedly replaced, and the using cost is reduced.

Description

technical field [0001] The invention relates to the field of copper stranded wire processing, in particular to a drying treatment device for the outer wall of copper wires. 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 of annea...

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.
