Problems solved by technology

[0003] The object of the present invention is to address the above-mentioned deficiencies and provide a wet-drawing method of aluminum-clad steel wire for electrical purposes, that is, a drawing method using grease or emulsion, or a lubricant prepared from emulsion and other media as the lubricating medium. Pulling method, changing the original powder contact into grease or emulsion contact, because the grease or emulsion film formed by grease or emulsion, or the lubricant prepared by emulsion and other media under constant pressure is very uniform Therefore, it solves the defect caused by uneven feeding of lubricating powder during the lubrication process

Embodiment 1

[0012] The wet-drawing process of aluminum-clad steel wire for electrical purposes is as follows:

[0013] 1. Produce semi-finished products of aluminum-clad steel wire on the coating production line according to different conductivity; place the semi-finished aluminum-clad steel wire (aluminum-clad steel wire coated on the coating production line) on the wire drawing production line;

[0014] 2. The semi-finished aluminum-clad steel wire is drawn through a wire drawing machine and a wire-drawing die for 6-12 passes. During drawing, the cavity of the wire-drawing die is filled with continuous constant-pressure grease, so that the gap between the aluminum-clad steel wire and the wire-drawing die is always maintained. Balanced lubricating grease film rather than direct contact; during the production process, both the drawing die and the drawing lubricating grease must be cooled with cooling water; the lubricating grease can be butter or aluminum disulfide lubricating grease.

[0018] 1. Produce semi-finished products of aluminum-clad steel wire on the coating production line according to different conductivity; place the semi-finished aluminum-clad steel wire (aluminum-clad steel wire coated on the coating production line) on the wire drawing production line;

[0019] 2. The semi-finished aluminum-clad steel wire is drawn through a wire drawing machine and a wire-drawing die for 6-12 passes. During drawing, a continuous constant-pressure emulsion is filled in the wire-drawing die cavity, so that the distance between the aluminum-clad steel wire and the wire-drawing die is always maintained. A balanced emulsion film rather than direct contact; during the production process, both the wire drawing die and the wire drawing emulsion must be cooled with cooling water; the emulsion can be used for metal cutting machine tools.

Abstract

A wet drawing method of Al-enclosing steel wires for electrotechnics in the invention relates to a method for drawing the Al-enclosing steel wires by using a lubricant as a lubricating medium, wherein the lubricant is prepared by lubricating grease or an emulsion and other mediums.

Description

technical field [0001] The aluminum-clad steel wire wet-drawing method for electricians of the present invention relates to a method for drawing aluminum-clad steel wire using grease or emulsion, or a lubricant prepared from emulsion and other media as a lubricating medium. Clad steel wire is widely used in bridges, railways, and electric power. Special-shaped aluminum-clad steel wire rods can be manufactured according to requirements. Background technique [0002] At present, aluminum-clad steel products are widely used in electric power, bridges, and railways. In terms of electricity, there are: wires, aluminum-clad steel-cored aluminum strands, and aluminum-clad steel strands; in bridges and railways: high-strength anti-oxidation load-bearing suspension cables, etc. The drawing method of the currently used aluminum-clad steel wire is a drawing method in which lubricating powder is used as a lubricating medium. During the production of this product, the amount of lubric...
