The invention belongs to electrochemistry electric arc processes field, particularly a kind of flexible electrical magnetic pole composite tool.
Background technology
Superhard metal material and metal-base composites are applied to industrial circles such as light industry papermaking, Aero-Space, electronics, automobile increasingly extensively.The processing method of present superhard material and metal-base composites mainly contains traditional machining process and comprises the special process method of Laser Processing, abradant jet processing, Electrolyzed Processing, spark machined etc.
Wherein the method for machining is processed superhard material; Must adopt the cutter harder than workpiece material; This has improved cost of processing undoubtedly greatly, and on the method processing metal based composites that adopts machining, violent tool wear and inferior surface quality are two still unresolved so far hang-ups; Its main cause is that the wild phase itself in the metal-base composites is exactly an abrasive particle; Have very high hardness, just the hardness than most cutter materials is high a lot of such as the hardness of SiC particle, and therefore violent tool wear also just is difficult to avoid when the processing said material.The result shows, even if the expensive diamond cutter of employing, though can delay the wearing and tearing of cutter to a certain extent, cutter life also often has only a few minutes.
Though Laser Processing, abrasive water-jet processing have higher working (machining) efficiency and need not to face the problem of tool wear; But result of study shows; The fire damage of Laser Processing is big and can make surface of the work produce defectives such as burr, cut and molten drop, also very easily produces harmful Al4C3 phase in addition during Laser Processing SiC/Al composite.Though abrasive water-jet processing does not have the thermal injury zone, yet its roughness of machining surface also can produce manufacturing deficiencies such as dentation fringe, and the precision of its processing is low in addition, therefore is difficult to satisfy industrial needs.Electrolyzed Processing can be processed superhard metal material and metal-base composites; The problem that does not also have tool loss in the process; Yet its machining accuracy is lower and for metal-base composites owing to there is the ceramic phase of a large amount of difficult electrolysis in the metal-base composites; These ceramic phases are difficult in time come off discharge in the process of processing; The metal that giving prominence to ceramic phase at surface of the work not only influences surface quality but also can treat machining area forms shielding mutually, thereby has reduced working (machining) efficiency, and result of study shows that the method processing metal based composites that adopts Electrolyzed Processing is difficult to obtain desirable working (machining) efficiency and surface quality.
Though the spark machined process velocity is lower,, be a kind of processing method that adopts often at present therefore because the machining accuracy of Wire EDM and edm forming is higher relatively and can process complicated 3D shape.Yet because the workpiece surface roughness value of spark machined is high, integrality is poor, therefore is difficult to satisfy the needs of commercial Application.Adopt in addition in the process of electric spark to metal-base composites, exposed non-conductive ceramic is met and is caused a large amount of abnormal arc discharge phenomenons, very easily causes electrode damage.
Electrochemistry arc process (electrochemistry spark technique) can reach to have than the high 5-50 of spark machined material removing rate and process doubly to be stablized.Yet the electric arc effect can cause the rapid loss of instrument in the process, compares with spark machined in addition, and its machined surface quality does not obtain substantial improvement yet.
The grinding effect has been proved to be and can have obtained high-quality finished surface and very high dimensional accuracy, and so its efficient is extremely low.Adopted the method for electrochemistry electric arc grinding Compound Machining not only to have the efficient more taller than electrochemistry electric arc processes; And can obtain the fine finished surface of integrality; Yet in process, the abrasive particle bond of tool surfaces can be removed by the electric arc effect rapidly, thereby causes abrasive particle to come off; Cause tool failures, cause processing to carry out.
Therefore, being accompanied by the continuous development of science and technology and society, the means and the process technology of superhard metal material of existing processing and metal-base composites can not satisfy industrialized demand.Press for the more advanced process technology of development.Particularly modern paper industry, aircraft industry, auto industry all presses for the technology that develops a kind of ability efficient high-quality moulding superhard material and metal-base composites in the mold manufacturing industry.
