Abstract

The invention discloses an automatic wire feeding device for micro electrical discharge machining. The automatic wire feeding device for micro electrical discharge machining is used for machining an electrode wire for micro electrical discharge machining. According to the automatic wire feeding device for micro electrical discharge machining, a wire-electrode cutting wire can be used as a tool electrode for micro electrical discharge machining, cost of micro electrical discharge machining is lowered, and machining efficiency is improved. Firstly, a user winds the electrode wire with a certain diameter around a wire reel, and the electrode wire reaches a conductive wheel through wire rectifying wheels, penetrates through a feeding system and a wire guide nozzle, and extends by a certain distance. The conductive wheel is connected with a micro electrical discharge machining power source to achieve conduction from the power source to the electrode wire. Switching-on and switching-off of the power source and feeding and retracting of the electrode wire are controlled a micro electrical discharge machining control system so as to achieve micro electrical discharge machining.

Description

technical field [0001] The invention relates to the field of micro electric discharge machining devices, in particular to an automatic wire feeding device for micro electric discharge machining. Background technique [0002] Electrical discharge machining (Electrical Discharge Machining, referred to as EDM) is in the working fluid medium, using the local high temperature and high pressure generated by the pulsed spark discharge between the tool electrode and the workpiece to etch the workpiece material to achieve a certain size, shape and surface roughness. It is also called "discharge machining" or "electric erosion machining". With the development and progress of science and technology, various new materials with high hardness, high strength, high brittleness, high viscosity and high purity are constantly appearing, and there are more and more parts with various complex structures and special process requirements, which brings great advantages to the manufacturing industry...
