Copper wire online annealing apparatus for communication cable

Abstract

The invention relates to a copper wire online annealing apparatus for a communication cable. The apparatus comprises a cabin body and a controllable DC source system. The cabin body is internally provided with two conductive wheels which are spaced and have their end surfaces in level arrangement; the conductive wheels are connected with the cabin body through shafts; the shafts are provided with carbon brushes; the controllable DC source system comprises a three-phase adjustable rectifier; and the three-phase adjustable rectifier rectifies three-phase AC power into a DC source for adding to the two conductive wheels through the carbon brushes, and copper wires on the two conductive wheels are energized and heated, such that the annealing purpose is realized. The copper wire online annealing apparatus for the communication cable can enable a copper wire drawing process, an annealing process and a subsequent process of extruding an insulation layer by the copper wires to be continuously produced and improves the work efficiency and the product quality.

Description

technical field [0001] The invention relates to the field of communication cable manufacturing, in particular to an online copper wire tempering device for communication cables. Background technique [0002] The copper wire used to make communication cables is generally very hard and brittle after being pulled out by a wire drawing machine, and it is easy to break after several times of bending or tension; in order to solve this problem, the existing technology is hard copper wire drawn by a wire drawing machine First wind up on an iron plate, then put dozens of hard copper wires together into a closed iron tank filled with N2, and heat them to a certain temperature and time to temper the copper wires; when this technology is tempered, It will cause uneven tempering degree of the inner and outer copper wires in each coil of copper wires in the iron tank, which will affect the product quality; and the wire drawing process, tempering process and subsequent copper wire extrusio...

Problems solved by technology

[0002] The copper wire used to make communication cables is generally very hard and brittle after being pulled out by a wire drawing machine, and it is easy to break after several times of bending or tension; in order to solve this problem, the existing technology is hard copper wire drawn by a wire drawing machine First wind up on an iron plate, then put dozens of hard copper wires together into a closed iron tank filled with N2, and heat them to a certain temperature and time to temper the copper wires; when this technology is tempered, It will cause uneven tempering degree of the inner and outer copper wires in each coil of copper wires in the iron tank, which will affect the product quality; and the wire drawing process, tempering process and subsequent copper wire extrusion insulation layer process are separated and cannot be carried out continuously, resulting in production The efficiency is low, and it is necessary to lead multiple times during production, which also leads to the waste of copper wire. For this reason, we have developed a method that can make the copper wire drawing process, tempering process and subsequent copper wire extrusion insulation layer process continuous production. Advanced copper wire online tempering device for communication cables improves work efficiency and product quality
