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 " electro-discharge machining " principle, and conductive material carries out galvanic corrosion (spark discharge), reaches to process purpose.Wire-cut Electrical Discharge Machining is without making shaped electrode, add man-hour, utilizing an one metal wire (generally molybdenum filament) as tool-electrode, to spark over workpiece, 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 leaves region of discharge, sprays into liquid medium between wire electrode and workpiece simultaneously, the orbiting motion that workpiece follow procedure under the control of the computer determines, finally obtains required form workpiece.Spark discharge adds man-hour, and in working region, temperature reaches 8000-10000 degree Celsius, and for ensureing that wire electrode is not ablated by high temperature, the scheme used in the industry is to spray into liquid medium between wire electrode and workpiece to cool down.Therefore, all to-and-fro thread feed electric spark wire-electrode cutting machines are equipped with water injector, development along with " middle wire " technology, the conventional water jet device being only capable of meeting water-spraying control effect can not fully meet the requirement of " repeatedly cutting " technique, its shortcoming is, one, chip is more, and easy Integrated Chip blocks hole for water spraying；Conventional water jet plate inner nozzle surface is a concave spherical surface, and hole for water spraying, on concave spherical surface, can produce a lot of chip during linear cutter, and cleaning is washed away and blocked by hole for water spraying not as good as being easy to gather, and causes water spray bad, processing instability, even fracture of wire etc.；Two, conventional water jet device electrodeless silk positioning function, owing to 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
It is an object of the invention to for deficiencies of the prior art, the location water injector of a kind of to-and-fro thread feed electric spark wire-electrode cutting machine is provided, the advantage that it has nozzle not Integrated Chip, processing is stable, wire electrode buffeting amplitude is little, is effectively increased surface accuracy and the product quality of workpiece.
For reaching above-mentioned purpose, the location water injector of the to-and-fro thread feed electric spark wire-electrode cutting machine of the present invention, including water spray plate, the nozzle being loaded in water spray plate, water spray plate is equipped with the silk groove being connected with the side of nozzle, liquid inlet channel it is provided with in water spray plate, nozzle is provided with the intake chute being connected with liquid inlet channel and the several spray orifices being 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, it is provided with chamfering on nozzle face outside all spray orifices, water spray plate with the water spray end opposite side of nozzle is installed with installing plate, dovetail groove it is provided with in installing plate, the opening of dovetail groove is consistent with silk groove, maintainance block is placed in dovetail groove, it is provided with the holding screw of fixing maintainance block on a mounting board, maintainance block uses diamond material.
Owing to being provided with chamfering on the nozzle face outside all spray orifices, beneficially chip etc. discharge, and are unlikely and accumulate on nozzle, it is ensured that water spray is stable, it is therefore prevented that fracture of wire, have the advantage that processing is stable；Maintainance block contacts gently with wire electrode simultaneously, reduces the buffeting amplitude of wire electrode, is effectively increased surface accuracy and the product quality of workpiece；Dovetail groove is easy to the installation of maintainance block, and holding screw can prevent maintainance block landing；
In sum, the advantage that the present invention has nozzle not Integrated Chip, processing is stable, wire electrode buffeting amplitude is little, it is effectively increased surface accuracy and the product quality of workpiece.

Detailed description of the invention
The present invention is further detailed explanation below in conjunction with the accompanying drawings.
As shown in Figures 1 to 5, the location water injector of this to-and-fro thread feed electric spark wire-electrode cutting machine, the nozzle 2 that including water spray plate 1, is loaded in water spray plate 1, it is fixedly arranged on water spray plate 1 upper mounting plate 3, water spray plate 1 is equipped with, with the side of nozzle 2, the silk groove 4 being connected, liquid inlet channel 5 it is provided with in water spray plate 1, nozzle 2 is provided with the intake chute 6 being connected with liquid inlet channel 5 and the several spray orifices 7 being connected with intake chute 6, the water spray end of nozzle 2 is positioned at outside the end face of water spray plate 1, and the nozzle face outside all spray orifices 7 is provided with chamfering 8；Installing plate 3 is positioned at, with the water spray end of nozzle 2, the both sides that water spray plate 1 is relative, being provided with dovetail groove 9 in installing plate 3, the opening of dovetail groove 9 is consistent with silk groove 4, and a maintainance block 10 is placed in dovetail groove 9, being provided with the holding screw 11 of fixing maintainance block 10 on installing plate 3, maintainance block 10 uses diamond material；Dovetail groove 9 is easy to the installation of maintainance block 10；
Maintainance block 10 uses the high temperature resistant and material such as the diamond of high rigidity or synthetic cut stone；During use, discharge owing to being provided with chamfering 8, beneficially chip etc. on the nozzle face outside all spray orifices 7, be unlikely and accumulate on nozzle 2, it is ensured that water spray is stable, it is therefore prevented that fracture of wire, there is the advantage that processing is stable；Maintainance block 10 contacts gently with wire electrode simultaneously, reduces the buffeting amplitude of wire electrode, is effectively increased surface accuracy and the product quality of workpiece.
