Problems solved by technology

However, due to factors such as cost reduction and cable weight reduction, the use of aluminum alloys instead of copper cores for welding machine cables is also under development. Pure aluminum cannot meet the requirements. The use of aluminum alloy wires must not only consider flexibility, but also That is, it can be drawn into a very thin monofilament, and the fatigue resistance and mechanical strength must also be considered to ensure that it will not be damaged during frequent movement. At the same time, it must also ensure that the electrical properties and corrosion resistance meet the requirements, so Facing many technical problems to be solved

Abstract

The invention discloses a conductor wire core aluminum alloy for a welding machine cable and a making method thereof. A conductor wire core is made of aluminum alloy materials. The aluminum alloy comprises the following compositions: 0.4-1.0wt percent of Fe or Co, 0.1-0.5wt percent of Cu, 0.1-0.5wt percent of Mg, 0.05-0.1wt percent of Be and 0.05-0.1wt percent of rare earth. An aluminum alloy wire harness is obtained by carrying out smelting, linecasting, rolling, intermediate annealing, drawing, bunch stranding and annealing on the alloy. The aluminum alloy wire core has the advantages of better conductivity, anti-fatigue performance, flexibility, bending performance and corrosion resistance and is suitable for the conductor wire core of the welding machine cable.

Description

technical field [0001] The invention belongs to the field of wire and cable manufacturing process design, and in particular relates to an aluminum alloy with a conductive core for electric welding machine cables and a manufacturing method thereof. Background technique [0002] Welding machine cable is a kind of cable used for special equipment and occasions. Due to the frequent movement, twisting and release of motor lead wire cables, the cables are required to have the characteristics of softness, good bending performance, light weight, and small outer diameter. Therefore, monofilament The diameter is required to be very thin, the maximum not exceeding 0.21mm. And the use of welding machine cables is more complex in environmental conditions, such as sunlight, boiling water, contact with muddy water, engine oil, acid-base liquids, etc., so it is required to have certain weather resistance, oil resistance, and solvent resistance. [0003] Due to the strict requirements of we...
