Wire surface treatment machine

Abstract

The invention relates to the field of wire processing, and discloses a wire surface treatment machine. The wire surface treatment machine comprises a shelling unit used for removing an oxide skin surface layer on the surface of a wire, a first straightening unit used for straightening the wire and a steel brush unit used for removing oxide skin on the surface of the wire. The first straightening unit is located between the shelling unit and the steel brush unit. The wire is in a tensioning state under the action of external force and moves to the steel brush unit from the shelling unit. The wire is bent through the shelling unit, and the oxide skin, poorly combined with a metal matrix, on the surface is removed. The wire enters the straightening unit from the shelling unit and is straightened from the bent state, and sufficient preparations are made for the wire for entering the steel brush unit; and the surface oxide skin is further removed in the process that the wire becomes straightened from bent. The wire enters the steel brush unit, the straightened wire can in sufficient contact with steel brushes, and omni-directional cleaning of the surface of the wire is achieved; the cleaning effect is good; the wire is level; colliding with the steel brushes is avoided; and the service life of the steel brushes is long.

Description

technical field [0001] The invention relates to the field of wire processing, in particular to a wire surface treatment machine. Background technique [0002] Metal wires are generally obtained by drawing or extrusion deformation, and the deformation needs to be annealed to a certain extent to eliminate the processing stress. The surface is oxidized during high temperature deformation or intermediate annealing, and the oxide scale on the surface will affect the subsequent processing deformation. [0003] In order to remove the scale on the surface, there are three surface treatment methods in the prior art: chemical methods, chemical and mechanical methods and mechanical methods. The chemical method mainly uses hydrochloric acid or sulfuric acid to react with the scale on the surface of the wire to eliminate the scale. The chemical and mechanical method is to add a polishing wheel to remove the surface oxide scale before pickling, and then pickle. These two methods can re...

Problems solved by technology

This method can only remove the oxide scale on the surface to a certain extent, which will affect the subsequent processing and reduce the quality of the finished wire rod. At the same time, the wire rod will cause great damage to the steel brush and reduce the service life of the steel brush. This method cannot be satisfactory. Effect
