Problems solved by technology

[0002] At present, there are few domestic enterprises that produce silver-plated copper-clad steel wires. Even if there are, the shallow diameter is more than φ0.20 mm, and the hot-dip plating method is used. As long as it is long, it is easy to fall off, resulting in a decrease in the conductivity of the product and the continuity of the coating. Some high-precision electronic products require silver-plated copper-clad steel wires below φ0.10 mm, and due to improper coating process of copper-clad steel, The copper layer breaks during drawing, but loses the low resistivity properties of the copper and steel bimetallic alloy

Embodiment

[0018] Embodiment: as shown in Figure 1, a kind of manufacturing method of silver-plated copper-clad steel wire for covered electronic product comprises the following steps:

[0019] (1) heat treatment to remove the oxide layer on the copper strip and steel wire surface;

[0020] (2) Alkali washing to remove oil stains on the surface of copper strips and steel wires;

[0021] (3) Cold-rolled argon arc seam welding of the copper strip, and longitudinally wrapping it on the steel wire;

[0022] (4) stretching;

[0023] (5) Annealing heat treatment;

[0024] (6) Electroplating silver on the surface of the copper-clad steel wire;

[0025] (7) Annealing heat treatment;

[0026] (8) Divide the finished product.

[0027] The cladding technology of the copper-clad steel wire in the present invention adopts the cold-rolled argon arc seam welding method, so that the copper strip is tightly longitudinally wrapped on the steel wire, and the copper molecules are re-contacted and mixed...

Abstract

Present invention discloses a silver-copper plated steel-clad wire manufacturing method for electronic products. It contains heat treatment, soda wash, cold rolling copper strip, argon arc seam welding, longitudinal coated on steel wire, stretching, annealing heat treatment, plating silver on copper clad steel wire, annealing heat treatment, and cutting finished product etc steps. Said invented cam draw copper clad steel wire to thin wire with diameter lees than o.10mm without broken layer, ensured high strength of copper steel thermometal composite material, with low resistance and high corrosion resistance.

Description

technical field [0001] The invention relates to a method for manufacturing a silver-plated copper-clad steel wire for a covered electronic product. Background technique [0002] At present, there are few domestic enterprises that produce silver-plated copper-clad steel wires. Even if there are, the shallow diameter is more than φ0.20 mm, and the hot-dip plating method is used. As long as it is long, it is easy to fall off, resulting in a decrease in the conductivity of the product and the continuity of the coating. Some high-precision electronic products require silver-plated copper-clad steel wires below φ0.10 mm, and due to improper coating process of copper-clad steel, The copper layer breaks during drawing, but loses the low resistivity properties of the copper and steel bimetallic alloy. Contents of the invention [0003] The object of the present invention is to provide a manufacturing method of silver-plated copper-clad steel wire for clad electronic products, adop...
