Abstract

The invention discloses a preparation method of a textured plating layer electrode wire. The preparation method comprises the following steps: a copper-zinc alloy is selected as a core material; firstly, an electroplating / hot dipping plating technology is used for preparing a metal zinc plating layer on the surface of a wire material; then, a discontinuous dispersion annealing technology is used for pretreating a plating layer electrode wire to obtain a plating layer electrode wire material with Zn / beta-Cu and gamma-Cu / alpha-Cu multilayer structures; and finally, multiple times of cold drawingtreatment and stress relief annealing treatment are used for modifying the electrode wire to obtain the textured plating layer electrode wire material. Compared with a copper alloy electrode wire anda zinc plating electrode wire, the material has such advantages as high cutting speed, low cutting cost and low environmental pollution, wherein the cutting speed can be accelerated by above 12% compared with the copper alloy electrode wire, the cutoff times are reduced by 30%, and the replacement time of a cooling water ion resin filter is prolonged by 10%.

Description

technical field [0001] The invention relates to the technical field of material surface treatment, in particular to a method for preparing an electrode wire with a textured coating structure with high cutting speed, low cutting cost and low environmental pollution. Background technique [0002] Slow wire cutting (WEDM-LS) is a wire electric discharge cutting technology, which uses continuously moving thin metal wires (called electrode wires, such as copper-zinc alloy wires, galvanized wires) as electrodes to cut workpieces A method of cutting and forming metals by pulsed spark discharge. At present, wire cutting (WEDM-LS) is also increasingly widely used in mold manufacturing, forming tools, precision small parts and special materials processing. Therefore, the demand for flexible electrode wire as a consumable is also increasing day by day, and has become a key factor affecting the surface finish and cutting efficiency of the cutting workpiece. With the development of WED...
