Abstract
The invention discloses a positioned water spray device of a reciprocating wire cut electrical discharge machining. The device comprises a water spray plate and a spray nozzle mounted in the water spray plate, wherein connected wire grooves are formed in one side of each of the water spray plate and the spray nozzle; a liquid inlet channel is arranged in the water spray plate; and the spray nozzle is provided with a liquid guide groove connected with the liquid inlet channel as well as a plurality of spray holes connected with the liquid guide groove. The device is characterized in that the water spray end of the spray nozzle is located outside an end surface of the water spray plate, and a chamfer is arranged on the spray nozzle end surface outside all the spray holes. The positioned water spray device has the advantages of absence of chip accumulation in the spray nozzle, stable processing and small wire electrode buffeting range, and improves the surface accuracy of workpieces and product quality effectively.
Description
Technical field
The present invention relates to a kind of water injector for to-and-fro thread feed electric spark wire-electrode cutting machine.
Background technology
The mechanism of Wire-cut Electrical Discharge Machining is to utilize " electric discharge processing " principle, and conductive material is carried out to galvanic corrosion (spark discharge), reaches processing object.Wire-cut Electrical Discharge Machining is without making shaped electrode, add man-hour, utilize an one metal wire (being generally molybdenum filament) as tool-electrode, workpiece is carried out to spark discharge, the positive pole of the pulse power connects workpiece, negative pole receiving electrode silk, wire electrode moves back and forth with certain speed, and it constantly enters and leave region of discharge, sprays into liquid medium between wire electrode and workpiece simultaneously, workpiece is the definite orbiting motion of follow procedure under computer control, finally obtains required form workpiece.Spark discharge adds man-hour, and in working region, temperature reaches 8000-10000 degree Celsius, and for guaranteeing that wire electrode is not lost by high-temperature molten, the scheme adopting is in the industry between wire electrode and workpiece, to spray into liquid medium to carry out cooling.Therefore, all to-and-fro thread feed electric spark wire-electrode cutting machines are all furnished with water injector, development along with " middle wire " technology, traditional water injector that only can meet water spray cooling effect can not meet the requirement of " repeatedly cutting " technique completely, its shortcoming is, one, chip is more, and easily Integrated Chip is blocked hole for water spraying; Tradition water spray plate nozzle inner surface is a concave spherical surface, and hole for water spraying, on concave spherical surface, can produce a lot of chips during line cutting processing, and cleaning is washed away not as good as being easy to gather hole for water spraying is blocked, and causes water spray bad, process unstable, fracture of wire etc. even; Two, the electrodeless silk of traditional water injector positioning function, because the wire electrode speed of service is very fast, it certainly exists shake, causes finished surface precision bad, and product quality is affected.
Summary of the invention
The object of the invention is for prior art above shortcomings, a kind of location water injector of to-and-fro thread feed electric spark wire-electrode cutting machine is provided, it have advantages of nozzle not stable, the wire electrode of Integrated Chip, processing to buffet amplitude little, effectively improved surface accuracy and the product quality of workpiece.
For achieving the above object, the location water injector of to-and-fro thread feed electric spark wire-electrode cutting machine of the present invention, comprise water spray plate, be loaded on the nozzle in water spray plate, one side of water spray plate and nozzle is equipped with the silk groove being connected, in water spray plate, be provided with liquid inlet channel, nozzle is provided with the intake chute being connected with liquid inlet channel and the several spray orifices that are connected with intake chute, it is characterized in that the water spray end of nozzle is positioned at outside the end face of water spray plate, on the nozzle face in all spray orifices outside, is provided with chamfering.
Owing to being provided with chamfering on the nozzle face in all spray orifices outside, be beneficial to chip etc. and discharge, be unlikely accumulating on nozzle, guaranteed that water spray is stable, prevented fracture of wire, have advantages of that processing is stable;
As a further improvement on the present invention, holding on the water spray plate of a contrary side and be installed with maintainance block with the water spray of nozzle; As preferably, holding on the water spray plate of a contrary side and be installed with installing plate with the water spray of nozzle, in installing plate, be provided with dovetail groove, the opening of dovetail groove is consistent with silk groove, and described maintainance block is placed in dovetail groove, is provided with the fixedly holding screw of maintainance block on installing plate; During work, dovetail groove is convenient to the installation of maintainance block, and holding screw can prevent maintainance block landing, and maintainance block is contacted gently with wire electrode, has reduced the buffeting amplitude of wire electrode, has effectively improved surface accuracy and the product quality of workpiece.
In sum, the present invention have advantages of nozzle not stable, the wire electrode of Integrated Chip, processing to buffet amplitude little, effectively improved surface accuracy and the product quality of workpiece.
