Wire-cut electrical discharge machining device

Abstract

The invention relates to the technical field of machine tools, in particular to a wire-cut electrical discharge machining device. The device comprises a machine body, a wire passing mechanism, a supporting column, a water feeding mechanism, a fixing mechanism, a metal wire, a mounting mechanism, supporting plates, an adjusting mechanism, a limiting mechanism and a cleaning mechanism, the metal wire rotates on the side wall of the wire passing mechanism, and the water feeding mechanism is installed at the bottom end of the wire passing mechanism. According to the device, when the metal is cut,the liquid in the water feeding mechanism converges into huge water flow and flows to the metal surface along with the metal wire, the melted metal is quickly washed away, attachments on the metal wire are reduced, the cleaning mechanism is installed at the bottom end of the wire passing mechanism, the metal wire moves up and down in a zigzag mode inside the cleaning mechanism, so that the surfaceof the metal wire is fully contacted with the interior of the cleaning mechanism to clean up metal attachments on the surface of the metal wire; the water feeding mechanism and the cleaning mechanismare located on the top end of the mounting mechanism, the liquid and the metal fragments directly fall on the v-shaped top surface of the mounting mechanism, so that the metal fragments can be conveniently washed away by the liquid.

Description

technical field [0001] The invention relates to the technical field of machine tools, in particular to a wire electric discharge cutting device. Background technique [0002] Electric spark wire cutting machine belongs to the category of electric processing. When the former Soviet Union Lazalianke and his wife studied the phenomenon and cause of the damage of switch contacts by spark discharge corrosion, they found that the instantaneous high temperature of electric spark can melt and oxidize local metal Corroded away, thus creating and inventing the electric discharge machining method. [0003] When using a wire electric discharge machine, the metal wire melts the workpiece, and some workpieces are absorbed on the surface of the wire after melting, resulting in an increase in the thickness of the surface of the wire, which is not conducive to the movement of the wire to conduct electricity; in view of this, the present invention provides a A wire electric discharge cutting...
