Problems solved by technology

[0005] In view of the above problems, the present invention provides a composite electrode wire and a preparation method and application of the composite electrode wire. The brass tubular outer material is directly set outside the core material of the conductive alloy, and then pressure cold packs are performed to make the core material of the conductive alloy It is directly and concentrically clad with the brass outer material, and then undergoes drawing, annealing and wire drawing treatment, so that the core material and the outer material form the final composite electrode wire. The surface of the composite electrode wire can be sprayed with zinc material coating, which solves the existing problem The technical problems of the surface of the composite electrode wire are not glossy and the overall strength is low

Abstract

The invention relates to the technical field of electrode wire machining, and concretely relates to a composite electrode wire, and a preparation method and application of the composite electrode wire. A conductive alloy core material is directly sleeved with a brass tubular outer material, then pressure cold wrapping is conducted to make the conductive alloy core material and the brass outer material directly and concentrically wrapped into a whole, then drawing, annealing and wire drawing treatment are carried out to make the core material and the outer material form the final composite electrode wire, and a zinc material coating can be sprayed on the surface of the composite electrode wire, so the technical problems that the surface of an existing composite electrode wire is not glossy, and the overall strength is low are solved.

Description

technical field [0001] The invention relates to the technical field of electrode wire processing, in particular to a composite electrode wire, a preparation method and application of the composite electrode wire. Background technique [0002] Composite conductors combine the characteristics of several different materials. Good adaptability is an obvious advantage of composite conductors. They not only have ideal electromechanical properties, but also have a wide range of applications. At present, in the domestic precision machining field, slow-moving wire-feeding equipment is widely used for precision cutting of materials. The cutting electrode wire used in slow wire walking is mainly made of brass, and the zinc element in the brass is vaporized at high temperature to wash away fine chips to improve the accuracy of the cutting surface. However, brass has a high hardness, and it is difficult to process it into a diameter below 0.2 mm, and its conductivity is limited, basical...
