Problems solved by technology

[0003] The purpose of the utility model of the present invention is to provide a wet-drawing method of aluminum-clad steel wire for electrical purposes, that is, a drawing method that uses lubricating oil as a lubricating medium to change the original powder contact into oil contact. , because the oil film formed by lubricating oil under constant pressure is very uniform, so it solves the defect caused by uneven feeding of lubricating powder in the lubricating process

Embodiment Construction

[0011] The wet-drawing process of aluminum-clad steel wire for electrical purposes is as follows:

[0012] 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;

[0013] 2. The semi-finished aluminum-clad steel wire is drawn through the wire drawing machine and the wire-drawing die for 6-12 passes. During drawing, the continuous constant-pressure lubricating oil is filled in the wire-drawing die cavity, so that the gap between the aluminum-clad steel wire and the wire-drawing die is always maintained. Balanced oil film rather than direct contact; during the production process, both the drawing die and the drawing oil must be cooled with cooling water;

[0014] 3. The finished aluminum-clad steel wire is taken up by the take-up machine.

Abstract

A wet drawing method for manufacturing the aluminium clad steel wire used for electric engineering is characterized by that the semi-finished aluminium clad steel wire is drawn through multi-pass drawing die by drawing machine while the lubricating oil is applied.

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 by using lubricating oil as a lubricating medium, and the aluminum-clad steel wire drawn by the method 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 lubricating powder enterin...
