Background technology
Spark erosion technique by the two poles of the earth of the pulse power are connected with electrode and workpiece respectively, when enough hour of the spacing of electrode and workpiece, interpolar generation discharge breakdown thus realize the removal of workpiece material.Spark discharge processing generally all needs to carry out in certain insulated working liquid medium, working solution has cooling region of discharge and ablation product is discharged the effect in ablation region, therefore working solution work in-process plays an important role, and can be improved the effect of spark machined by the flowing of reasonable adjusting control working solution to a great extent.
At present, the main working solution type of flow lifts certain height by step control electrode to the direction in contrast to workpiece, and then get back to the method for processing stand, region of discharge is made to have one to suck the effect of then discharging to working solution, thus take the ablation particle of region of discharge out of region of discharge, this method is bad compared with effect during deep hole in processing.By punching on electrode, add man-hour passing hole from the method for region of discharge by the sucking-off of ablation particle, the method that its effect lifts electrode relative to batch (-type) has some improvement, but its scope of application is only limited to punching on electrode can not affect the situation of work pieces process.Chinese patent bulletin CN1397399 proposes a kind of method that draw ratio adds guider guiding at the simple hollow long electrode of more than 30:1 and simplifies the manufacture of electrode, but the use of this electrode needs the auxiliary installation more complicated of guider, and rush liquid in self and directly cannot rush at electrode front end region of discharge and there is topping up dead angle.
Utility model content
The utility model rushes liquid in the electrode self in order to solve existing spark machined directly to rush at electrode front end region of discharge, cause there is topping up dead angle, and device is complicated, the inefficient problem of spark machined.A kind of novel electric discharging machining electrode is now provided.
A kind of novel electric discharging machining electrode, it comprises a cylinder electrode for processing work and No. two cylinder electrodes for connecting electrode, No. two cylinder electrodes are positioned at the upper end of a cylinder electrode and coaxially place with a cylinder electrode, the diameter of No. two cylinder electrodes is greater than a cylinder electrode, a cylinder electrode and No. two cylinder electrodes are integrated part structure, the bottom of a cylinder electrode is electric discharge machining area, No. two cylinder electrodes outside a cylinder electrode are arranged the ostium excurrens of multiple equally distributed same diameter, described ostium excurrens is as the flow pass of working solution, working solution is by splashing to a cylinder electrode outer arm after aperture, in the axial location of No. two cylinder electrodes and a cylinder electrode, an interior apopore is set, multiple ostium excurrens of described No. two cylinder electrodes and in the intracardiac apopore working solution gone out for cooling electrode, the ablation particle that electric discharge processing produces is gone out region of discharge.
The beneficial effects of the utility model are: the structure of this electrode is a cylinder electrode for processing work and another No. two cylinder electrodes for connecting electrode, a cylinder electrode and No. two cylinder electrodes are integrated part structure, No. two cylinder electrodes are positioned at the upper end of a cylinder electrode, the diameter of No. two cylinder electrodes is greater than a cylinder electrode, wherein on a cylinder electrode, in the scope of its lateral wall to No. two cylinder electrode lateral walls, process series of holes, and the heart processes a larger apopore in the electrodes.During application, diameter thinner section is used for processing, when working solution flows out from the larger end of diameter, centre bore can cooling electrode take away part near the ablation particle of centre bore, the working solution of the aperture outflow of periphery then againsts path periphery and is surrounded completely by cylinder lower end region of discharge, working solution directly fills to region of discharge, therefore fast main ablation particle can be gone out region of discharge, and by discharging gap deionization.This electrode, without the need to auxiliary outer punching, just achieves the effect of topping up without dead angle, and the simple convenient operation of this apparatus structure, be conducive to the efficiency improving spark machined.
