Abstract

The invention discloses a high-difficulty steel core wire electrode and a manufacturing method thereof. The high-difficulty steel core wire electrode comprises a core material, a middle clad layer and an outer clad layer. The core material is prepared from raw materials including, by weight, 30-54 parts of iron, 30-55 parts of carbon, 1.5-2.4 parts of tin, 4-9 parts of chromium, 1-3 parts of manganese, 2-5 parts of molybdenum, 1.3-5.1 parts of nickel, 2.3-5.4 parts of silicon, 3-6 parts of tungsten, 3-4 parts of vanadium, 2-6 parts of phosphorus, 5-10 parts of sulphur and 12-15 parts of heat conducting filler. The steel core wire electrode is a composite wire and is composed of the steel core, the middle red copper clad layer and the outer brass clad layer. At the normal temperature, the steel core and a brass wire almost have the same tensile strength, but with the increase of temperature, the tensile strength of the brass wire is rapidly reduced, and the tensile strength of the steel is higher than that of the brass wire. The red copper layer is wrapped outside the steel core to improve the electric conductivity, and the outer brass layer plays a role in improving the washing performance.

Description

technical field [0001] The invention relates to the field of electrode wires, in particular to a high-difficulty steel-core electrode wire and a preparation method thereof. Background technique [0002] The core material is ordinary brass, and the surface is coated with a layer of zinc. Due to the gasification effect of zinc during the cutting process, the discharge of this electrode wire will be relatively stable, and the cut surface will be smoother than ordinary brass wire. However, the common problem in the use of this kind of electrode wire is powder falling, which is also faced by domestic and foreign manufacturers. [0003] The principle of EDM is to remove excess metal based on the electric corrosion phenomenon of pulsed spark discharge between the tool and the workpiece (positive and negative electrodes) in a certain medium, so as to achieve the size, shape and surface quality of the parts. Wait for the scheduled processing requirements. EDM is mainly used in mo...
