For solving the discharge loss problem of tool-electrode; Promote the application of edm at the superhard material manufacture field; Since the eighties in last century; People study the technology of related electrode loss balancing with regard to beginning; Successively proposed the finishing of electrode off-line, electrode finishing on the throne and multiple solutions such as export license on-line measurement and compensation, but these methods have bigger distance from producing practicality, the problem of the loss balancing in the normal electrode edm process still is not well solved at present.
Summary of the invention
In order to overcome the shortcoming and defect of prior art, the present invention provides a kind of simple in structure, application form is flexible and tool life is long selfreparing electromagnetic pole instrument and discharge-treating method.
The present invention realizes through following technical proposals:
A kind of selfreparing electromagnetic pole instrument discharge-treating method comprises the steps:
(1) increases one deck magnetic blow out coating on the tool body surface of electromagnetic pole instrument;
(2) in the process of workpiece, the electromagnetic pole instrument connects rotating shaft and connects the negative pole of power supply, and workpiece connects the positive pole of power supply, and the electromagnetic pole instrument rotates under the drive of rotating shaft, and the magnetic blow out coating on tool body surface carries out edm to workpiece;
(3) in the process of workpiece, discharge loss will take place in the magnetic of magnetic blow out coating, and the magnetic of loss replenishes through the magnetic replensiher.
A kind of selfreparing electromagnetic pole instrument, the electromagnetic pole instrument comprises tool body, and the magnetic blow out coating of the surface attachment of tool body.
Said electromagnetic pole instrument also comprises a scraper plate, and an end of scraper plate cooperates with the tool body surface gap.
The invention has the beneficial effects as follows:
The electromagnetic pole instrument constitutes by the magnetic blow out coating (magnetic conductive powder) of tool body and its surface adsorption is common, and the electromagnetic pole instrument rotates in the process, and the magnetic of extraneous supply will be attracted on the tool body surface; And forming uniform magnetic blow out coating auxiliary (also can be auxiliary) down of scraper plate without scraper plate, the discharge effect in the process will take place on this magnetic blow out coating, though discharge effect can cause the magnetic loss of magnetic blow out coating; Yet the magnetic of loss can constantly be replenished in process; So back and forth, the body that can make tool is effectively protected in process, and the geometry that can make tool is recovered timely; This will greatly prolong the life-span of instrument undoubtedly; Guarantee the precision of processing and reduced cost of processing, in addition, in the process; Magnetic field also will further promote the removal of material also can improve the stability of process widely to the Lorentz force of charged particle; Therefore this patent with the new method of setting up a kind of effective instrument selfreparing edm, thereby solves the export license difficult problem of conventional tool electrode in the edm process.
The patent art means are simple and easy to do, have positive technique effect.

The specific embodiment
Following specific embodiments of the invention is done further detailed explanation, but embodiment of the present invention is not limited thereto.
Like Fig. 1, Fig. 2, shown in Figure 3, selfreparing electromagnetic pole instrument discharge-treating method of the present invention comprises the steps:
(1) increases one deck magnetic blow out coating 6 on tool body 7 surfaces of electromagnetic pole instrument 1;
(2) in the process of workpiece 5; Electromagnetic pole instrument 1 connects rotating shaft 24 and connects the negative pole of power supply 22; Workpiece 5 connects the positive pole (perhaps according to the needs of reality processing, electromagnetic pole instrument 1 also can connect rotating shaft 24 and connect the positive pole of power supply 22, and workpiece 5 connects the negative pole of power supply 22) of power supply 22; Electromagnetic pole instrument 1 rotates under the drive of rotating shaft 24, and 6 pairs of workpiece of magnetic blow out coating 5 on tool body 7 surfaces carry out edm;
(3) in the process to workpiece 5, discharge loss will take place in the magnetic of magnetic blow out coating 6, and the magnetic of loss can replenish through magnetic replensiher 13.
Said electromagnetic pole instrument 1 comprises tool body 7, and the surface attachment of tool body 7 has magnetic blow out coating 6.
Said electromagnetic pole instrument 1 also can comprise a scraper plate 8, and an end of scraper plate 8 cooperates with tool body 7 surface gap.
In the process, electromagnetic pole instrument 1 constantly rotates, in rotary course; Tool body 7 surfaces are down auxiliary scraper plate 8; Can adsorb the layer of even magnetic, this magnetic constitutes magnetic blow out coating 6, and the formation thickness of magnetic blow out coating 6 can be controlled (also can not need scraper plate 8 to assist and directly formation) through scraper plate 8.
In the process, the magnetic of magnetic blow out coating 6 is constantly removed by discharge effect, so can constantly be replenished under the effect of magnetic field at magnetic, makes the magnetic blow out coating 6 on tool body 7 surfaces constantly to rebuild.
