One end of the wire electrode is wound around a rotary shaft of the rotary damper, and the other end of the wire electrode passes around the pair of the guide wheels to be fixed to a rotary shaft of the motor. The rotary spindle is located above the gap between the guide wheels. A liquid spray electrodeis arranged on the horizontal platform and is provided with a liquid inlet and a liquid spray outlet communicating with the liquid inlet. The electrolyte supply module is connected with the liquid inlet of the liquid spray electrode through a guide pipe. The negative pole of the high-voltage pulse power supply is electrically connected with the wire electrode, and the positive pole of the high-voltage pulse power supply is electrically connected with the liquid spray electrode.

Description

technical field [0001] The invention relates to the technical field of wire cutting, in particular to an electrolysis electric spark synchronous composite wire cutting processing device. Background technique [0002] Electrolytic EDM is a special processing technology. It uses high-voltage pulse power supply and low-voltage DC power supply for composite processing. The high-voltage pulse is conducive to the generation of spark discharge after the breakdown of the working fluid in the inter-electrode gap, and removes the difficult-to-process parts of electrolytic machining. Allows electrolytic machining to continue. Compared with the electrolytic machining method, some difficult-to-machine materials will have an oxide film during conventional electrolytic machining, which prevents the further progress of the reaction. Compared with EDM, the electrolyte with good conductivity is used as the working fluid, and the flow speed of the electrolyte between the workpiece and the too...
