Abstract

The utility model discloses a positioning water spraying device for a reciprocating wire-moving electrospark wire-electrode cutting machine tool. The device comprises a water spraying plate and a nozzle arranged in the water spraying plate, wherein wire grooves which are connected are formed in one side of the water spraying plate and the nozzle respectively, a liquid inlet passage is formed in the water spraying plate, and the nozzle is provided with a liquid guiding groove which is connected with the liquid inlet passage and a plurality of spraying holes which are connected with the liquid guiding groove. The device is characterized in that the water spraying end of the nozzle is positioned outside the end surface of the water spraying plate, and a chamfering is arranged on the end surface of the nozzle outside all the spraying holes. The device has the advantages that scraps are not stacked in the nozzle, the device is stable to process, the buffeting range of electrode wires is small, and the surface accuracy of workpieces and the product quality are effectively improved.

Description

The location water injector of to-and-fro thread feed electric spark wire-electrode cutting machine
Technical field
The utility model 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 ensureing 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, along with the development of " 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 when 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, even fracture of wire etc.; 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 purpose of this utility model 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 utility model, 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, ensure that water spray is stable, prevent fracture of wire, have advantages of that processing is stable;
As further improvement of the utility model, 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 holding screw of fixing maintainance block on installing plate; When 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 utlity model has nozzle not stable, the wire electrode of Integrated Chip, processing buffet the little advantage of amplitude, effectively improved surface accuracy and the product quality of workpiece.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figures 1 to 5, the location water injector of this to-and-fro thread feed electric spark wire-electrode cutting machine, comprise water spray plate 1, be loaded on nozzle 2 in water spray plate 1, be fixedly arranged on water spray plate 1 upper mounting plate 3, one side of water spray plate 1 and nozzle 2 is equipped with the silk groove 4 being connected, in water spray plate 1, be provided with liquid inlet channel 5, nozzle 2 is provided with the intake chute 6 being connected with liquid inlet channel 5 and the several spray orifices 7 that are connected with intake chute 6, the water spray end of nozzle 2 is positioned at outside the end face of water spray plate 1, on the nozzle face in all spray orifices 7 outsides, is provided with chamfering 8; Installing plate 3 is positioned at the water spray end of nozzle 2 both sides that water spray plate 1 is relative, is provided with dovetail groove 9 in installing plate 3, and the opening of dovetail groove 9 is consistent with silk groove 4, and maintainance block 10 is placed in dovetail groove 9, is provided with the holding screw 11 of fixing maintainance block 10 on installing plate 3; Dovetail groove 9 is convenient to the installation of maintainance block 10;
Maintainance block 10 adopts the high temperature resistant and material such as diamond or synthetic cut stone high rigidity; When use, owing to being provided with chamfering 8 on the nozzle face in all spray orifices 7 outsides, being beneficial to chip etc. and discharging, be unlikely accumulating on nozzle 2, ensured that water spray is stable, prevented fracture of wire, have advantages of that processing is stable; Maintainance block 10 contacts gently with wire electrode simultaneously, has reduced the buffeting amplitude of wire electrode, has effectively improved surface accuracy and the product quality of workpiece.
