Novel lead-free environment-friendly copper alloy wire

Abstract

The invention belongs to the technical field of wires, and particularly relates to a novel lead-free environment-friendly copper alloy wire which comprises an outer sleeve and a wire pipe, the inner wall of the circumference of the outer sleeve is connected with the wire pipe in a sleeved mode, the inner wall of the circumference of the outer sleeve is connected with a forced limiting groove ring in a sleeved mode, a round hole is formed in the top of the forced limiting groove ring, and an inserting and pulling column pile is inserted in the inner wall of the round hole. According to the novel lead-free environment-friendly copper alloy wire, through combined application of accessories, a forced limiting groove ring carrying the inserting and pulling column pile is arranged in the outer sleeve, a built-in clamping ring is installed in the inserting and pulling column pile, and the forced limiting groove ring, the inserting and pulling column pile and the built-in clamping ring are matched with the outer sleeve clamping ring outside the outer sleeve, a four-point limiting structure is formed, it is ensured that the wire pipe carrying core wires is effectively arranged inside, meanwhile, the combination stability is improved, the stability is high when the wire pipe is used in a severe environment, the copper alloy wires are well protected, the mode that multiple strands are evenly distributed after being leased is adopted, the risk of one-time breakage of the copper alloy wires is reduced, and the error-tolerant rate is increased.

Description

technical field [0001] The invention relates to the technical field of wire rods, in particular to a novel lead-free and environment-friendly copper alloy wire rod. Background technique [0002] Copper alloy is an alloy composed of pure copper as the base and adding one or several other elements. Pure copper is purple-red, also known as red copper. According to the alloy system, it can be divided into unalloyed copper and alloyed copper. Unalloyed copper includes high-purity Copper, ductile copper, deoxidized copper, oxygen-free copper, etc., can be divided into cast copper alloy and deformed copper alloy according to the forming method of the material. [0003] Copper alloy wire rod is one of the most widely used steel products. It can be used in various environments. After rolling, it can be directly used for reinforcement of reinforced concrete and welded structural parts, and can also be used after reprocessing, for example, after drawing Pulled into various specificati...

Problems solved by technology

[0005] The purpose of the present invention is to provide a new type of lead-free environment-friendly copper alloy wire to solve the problem that the existing copper alloy wire proposed in the above background technology will appear in the process of use due to the influence of the use environment, use mode and service life. The position of itself is offset, which leads to a decrease in the use stability of the copper alloy wire, and the protection performance of the copper alloy wire is poor. In the event of an accidental break, it will break once, and the fault tolerance rate is poor, which reduces the actual use. security issues
