Embodiment 1

[0011] a. Use existing mechanical or chemical methods to remove the oxidation passivation layer on the surface of the copper strip and the steel wire with a diameter of 6 mm, and wrap the copper strip on the steel wire with a diameter of 6 mm to make a core and clad composite blank ;

[0012] b. Draw the composite blank with a speed of 100m / min and a diameter reduction rate of 18%, to form a composite wire with a diameter of 1.5mm;

[0013] c. Adjust the drawing speed to 2500m / min, draw with a diameter reduction rate of 3%, and draw to a diameter of 0.025mm to make a copper-clad steel fine wire with a diameter of 0.025mm.

Embodiment 2

[0015] a. Use existing mechanical or chemical methods to remove the copper strip and the oxidation passivation layer on the surface of the aluminum rod with a diameter of 8 mm, and wrap the copper strip on the aluminum rod with a diameter of 8 mm to make a core and a cladding layer Composite blank;

[0016] b. Draw the composite billet with a speed of 150m / min and a diameter reduction rate of 13% to form a composite wire with a diameter of 1.5mm;

[0017] c. Adjust the drawing speed to 1500m / min, draw with a diameter reduction rate of 6%, and draw to a diameter of 0.25mm to make a copper-clad aluminum fine wire with a diameter of 0.25mm.

Embodiment 3

[0019] a. Use existing mechanical or chemical methods to remove the copper strip and the oxidation passivation layer on the surface of the aluminum rod with a diameter of 10mm, and wrap the copper strip on the aluminum rod with a diameter of 10mm to make a core and a cladding layer Composite blank;

[0020] b. Draw the composite blank with a speed of 100m / min and a diameter reduction rate of 16%, to form a composite wire with a diameter of 1.5mm;

[0021] c. Adjust the drawing speed to 1000m / min, draw with a diameter reduction rate of 12%, and draw to a diameter of 1.0mm to make a copper-clad aluminum fine wire with a diameter of 0.5mm or 1.0mm.

Abstract

The invention discloses a minuteness composite conductor. It is formed by the composition of the core body and covering. Its diameter is from 0.0025mm to 1.0mm. Its production method is as the following steps that the steel wire or aluminum rod whose diameter is from 6mm to 10mm is covered by copper to form composite body stock. The diameter of the composite body stock is drawing to 1.5mm with the speed from 100m / min to 150m / min, and thirteen percent to eighteen percent diameter reducing rate. Then it is drawing from 0.025mm to 1.0mm with the adjusted speed from 1500m / min to 2500m / min, and three percent to twelve percent diameter reducing rate.

Description

Technical field: [0001] The invention relates to a composite wire, in particular to a fine composite wire with a diameter of 0.025-1.0 mm and a production method thereof. Background technique: [0002] At present, there are many patents on composite wires such as copper-clad aluminum, copper-clad steel, and stainless steel-clad steel, but their production methods are basically Chinese invention patent application No. 98112410.0, named "a copper-aluminum composite wire and its production The method disclosed in "Technology", that is, "after the fully annealed copper strip (or copper pipe) and the surface passivation layer of the aluminum rod are removed with a wire wheel, the aluminum rod is wrapped into the copper strip by the cladding method, and the copper The strip is bent into a tubular shape, welded in a protective atmosphere, or the aluminum rod is put into the copper tube by the casing method to make a composite billet, and then the cladding is stretched, extruded or ...
