Abstract

The invention provides a continuous annealing wire drawing machine and a bare copper wire surface quality improvement method, and relates to the technical field of a continuous annealing treatment device for a bare copper wire. The invention solves a jittering damage of the bare copper wire in the continuous annealing wire drawing machine in the prior art and the technical problem of affecting surface quality of the bare copper wire due to local sparking caused by friction with a conducting wheel. The device comprises a conducting wheel and a vibration damping device, wherein the vibration damping device is arranged in front of the corresponding conducting wheel along the line direction of the bare copper wire in the continuous annealing wire drawing machine, and the vibration damping device can reduce vibration and / or clean the bare copper wire passing through the device. The surface quality of the continuous annealing bare copper wire can be improved.

Description

technical field [0001] The invention relates to the technical field of continuous annealing treatment devices for bare copper wires, in particular to a continuous annealing wire drawing machine and a method for improving the surface quality of bare copper wires by using the continuous annealing wire drawing machine to process bare copper wires. Background technique [0002] With the continuous improvement of customers' quality requirements for enameled wire products, in order to obtain high-quality enameled wires, it is necessary to improve all aspects of materials, production processes, etc., in order to finally effectively improve the quality level of enameled wire products. The important material of enamelled copper round wire is bare copper wire. The surface quality of bare copper wire directly determines the quality level of downstream enameled round copper wire, which affects the pinhole, withstand voltage, and smoothness of wire surface appearance, etc. The quality le...
