Description
Technical field
The utility model relates to Wire EDM apparatus field, particularly relates to a kind of WEDM liquid-jet device.
Background technology
WEDM (Wire cut Electrical Discharge Machining is called for short WEDM), belong to electric machining category, when studying switch contact by the phenomenon of spark discharge corrosion and damage and reason by former Soviet Union La Zhalinke Mr. and Mrs, find that the TRANSIENT HIGH TEMPERATURE of electric spark can make the metal molten of local, oxidation and being corroded, thus started and invented electric discharge machining method.Operation principle is that free cation and electronics accumulate in field, forms a conductive channel be ionized very soon.In this stage, between two plates, form electric current.Cause occurring between particle to collide many times, form an ion plasma, and be elevated to the high temperature of 8000 to 12000 degree very soon, at two some materials of conductive surface instant melting, meanwhile, due to the vaporization of electrode and electrolyte, form a bubble, and its pressure rule rises until very high.Then current interruptions, temperature reduces suddenly, causes bubble implosion, and the power of generation is dished out the material dissolved crater, and the material be then corroded regelation in electrolyte becomes little spheroid, and is drained by electrolyte.Then the monitoring controlled by NC and management and control, servo control mechanism performs, and make this electric discharge phenomena uniformity, thus it is processed to reach machining object, makes it the product becoming size and the form accuracy meeted the requirements.
Traditional high speed to-and-fro thread feed electric spark cutting, feed liquid way wants cast-type feed flow, working solution is brought interpolar into by the wire electrode of high-speed motion and is cooled, because the working solution brought into by wire electrode under " the unidirectional wire of low speed " condition reduces, this can cause certain influence to the interpolar state of cooling, easily cause wire electrode to blow and surface of the work differential annealing, make that work piece cut precision is low, surface quality is poor.
Utility model content
The technical problem that the utility model mainly solves is to provide a kind of WEDM liquid-jet device, structure is simple, working solution can enter in the discharging gap of workpiece and wire electrode preferably, improve the interpolar state of cooling, thus make electronic wire loss little, fracture of wire probability reduces greatly, can improve work piece cut precision and surface quality simultaneously.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: provide a kind of WEDM liquid-jet device, comprise: working solution, conveyance conduit and nozzle, described working solution is delivered to nozzle by conveyance conduit, described nozzle has a pair, symmetry is arranged between lower tumbler, wire electrode is through described nozzle, and the working solution in described nozzle is brought in the discharging gap of workpiece and wire electrode, described nozzle is horn-like, described nozzle interior is provided with filar guide, the jet hole of described nozzle is right against surface of the work, and the distance of described jet hole and surface of the work is 3-5mm.
