The purpose of this utility model provides a kind of with the reverse little hole processor of high-speed electric spark towards liquid device, brings the crudy difference and the low problem of working (machining) efficiency in workpiece to be machined hole because of leakage to overcome the existing little hole processor of high-speed electric spark when just punching.
Summary of the invention
For achieving the above object, the technical solution adopted in the utility model is: a kind of with the reverse little hole processor of high-speed electric spark towards liquid device, mainly by main frame, power controling box and working solution feedway are formed, wherein, the hollow electrode that is clamped on the swivel head is connected through pipeline with the working solution feedway, high-pressure work liquid sprays from the electrode endoporus, with interior liquid-charging type machining area is cooled off and chip removal, be provided with one oppositely towards liquid device in the exit in the processed hole of workpiece, this oppositely is made of shower nozzle and respective line towards liquid device, shower nozzle is placed in the exit in processed hole, its orifice center is pointed to the center of hollow electrode, and pipeline is connected with the working solution feedway.Add man-hour, oppositely working solution is sprayed in the exit in the processed hole of workpiece towards liquid device spray orifice mouth from this.
Related content and change interpretation in the technique scheme are as follows:
1, in the such scheme, oppositely settle towards the shower nozzle axis and the hollow electrode axis coaxle of liquid device, orifice center is pointed to the hollow electrode center.
2, in the such scheme, oppositely on the shower nozzle of liquid device, can a hole be set, also a plurality of holes can be set at middle position.Can there be certain angle at this center, hole with an axis.The shape circle of spray orifice, square, triangle, annular or other geometry.
3, in the such scheme, oppositely generally be fixedly mounted on the machine pillar towards liquid device, accurately constant with the relative position that guarantees orifice center and hollow electrode center.
4, in the such scheme, oppositely a hand-operated valve can be set in the pipeline of liquid device or automatic valve is controlled oppositely opening or closing towards liquid.
The utility model operation principle is: the exit position in the processed hole of workpiece of original high-speed electric spark aperture processing machine hollow electrode correspondence establishes one oppositely towards the liquid shower nozzle, when has just punched when leakage occurring and causing machining area to lack liquid in the processed hole of workpiece, the spray orifice mouth of this shower nozzle plays auxiliary cooling and chip removal effect to the working solution of the machining hole outlet injection certain pressure of workpiece to the machining hole exit region.Can remedy some adverse consequences of bringing because of leakage like this, further improve the machining accuracy and the working (machining) efficiency of hole exits.
Because the technique scheme utilization, the utility model compared with prior art has following advantage:
1, the utility model machining hole outlet just punched the processing district leakage lack liquid this in particular cases, can force cooling and chip removal to this machining area, processing can be proceeded smoothly, can further improve the working (machining) efficiency in hole.
2, the utility model adopts shower nozzle direct injection working solution to processed hole exits zone, and its cooling effect is better, avoids burn, has improved the surface quality of machining hole.
3, the utility model can punch processed hole owing to guaranteed the cooling and the chip removal effect of machining area smoothly, has reduced the processing tapering in hole, has improved the machining accuracy in hole.
4, the utility model is simple in structure, is skillfully constructed, and the utility model has been brought into play useful effect for overcoming the prior art deficiency, and has obtained obvious effects, therefore is compared with the prior art to have tangible creativeness.
