Abstract

The invention discloses a preparation method of amorphous alloy wires and an electric drawing device. Based on the electro-plastic principle of metal materials, pulse current is applied to the materials in the drawing process so as to improve the plasticity of the materials, multi-pass drawing can be conducted on amorphous alloy which is difficult to cold-machine, and thus the amorphous alloy wires with different wire diameters are obtained. The electric drawing device comprises a first guide wheel, a first electrified electrode, a first insulating module, a machining die, a second insulating module, a second electrified electrode, a pulse power supply device, a cooling device and a second guide wheel. The two guide wheels pull the materials to move, the pulse power supply device is used for applying pulse current to the materials through the two electrodes, and formed materials are obtained after the materials are cooled at the output end of the machining die. The preparation method and device can be used for continuously producing the amorphous alloy wires with controllable wire diameters, and digital control over the preparation process is achieved; and the preparation method and device have the advantages that the automation degree is high, operation is easy, and safety and reliability are achieved, and have important significance for the development of preparation methods of the amorphous alloy wires.

Description

technical field [0001] The invention belongs to the technical field of materials, and in particular relates to a method for preparing an amorphous alloy wire and an electric drawing device. Background technique [0002] Amorphous alloy is a new type of alloy material with many unique mechanical and functional properties. Its strength is higher than that of ordinary metals, and its strength, corrosion resistance and other functional properties are far superior to those of conventional polycrystalline alloys. Amorphous alloy wire can be applied because of its high strength, high elastic limit, high specific resistance, high magnetostriction, high magnetic permeability, high residual magnetic induction and saturation magnetic induction, and low coercive force. Used in the electronics industry, chemical industry, machinery industry and aerospace industry, etc., to manufacture various transformers, converters, sensors, strain gauges, precision springs, fiber reinforced materials,...
