Abstract
Provided is a base plate electrode of an electrosparking mould. A machining center is used for machining more than two parallel electrospark electrode machining curve faces with the same shapes and structures at the same time on a copper-tungsten alloy plate to form the base plate electrode. The electrospark electrode machining curve faces are reversed profiles and are manufactured according to machined curve face shaped needed by a mould punch with the machining center. When the base plate electrode is used for electrosparking of a hard alloy mould punch, after a first electrical discharge machining zone finishes machining, an electrospark forming machine reaches to a second machining zone through an X-axis or Y-axis offset, and the curve face of the mould punch can be directly machined by electrical discharge until the base plate electrode finishes machining on the whole mould punch curve face. More than two electrospark electrode machining curve faces are arrayed on the base plate electrode, the machining center can be used for one-time machining, once a machining zone is located at one time, machining can be directly carried out, machining time is saved, machining accuracy is guaranteed, consumption is lowered, and mould quality is improved.
Description
Technical field
The utility model relates to mold machining technology, particularly relates to a kind of electrode of substrate of electrical spark working tool and mould.
Background technology
Since the scientist La Zhalinke Mr. and Mrs of former Soviet Union invention spark machined (electrical discharge machining in 1943, EDM) since method, research and development through over half a century, spark machined has become a kind of important manufacturing process, obtains a wide range of applications in fields such as machinery, aerospace, electronics, instrument, light industry, automobiles.In recent years, along with modern science and technology, especially microelectronics, automatically control and the continuous progress of computer technology, spark erosion technique has obtained develop rapidly.Spark machined is carried out in liquid medium, the auto-feed adjusting device of lathe makes the suitable discharging gap of maintenance between workpiece and tool-electrode, when applying very strong pulse voltage (reaching the breakdown voltage of gap medium) between tool-electrode and workpiece, can puncture dielectric insulation intensity lowest part.Because region of discharge is very little, discharge time is extremely short, so energy height is concentrated, and makes the temperature of region of discharge instantaneous up to 10000-12000 ℃, and the metal local melting on surface of the work and tool-electrode surface, vaporization even.The metal of local melting and vaporization is thrown into working solution under the effect of explosive force in, and be cooled to small metal particles, then washed from rapidly the workspace by working solution, thereby make surface of the work form a small pit.Once after the discharge, the dielectric strength of medium recovers to wait for discharge next time.So repeatedly make surface of the work constantly by ablation, and copy the shape of tool-electrode on workpiece, thereby reach the purpose of processing and forming.
The sintered-carbide die material has its high strength (bending strength 1800～4100N/mm
2), high rigidity (HRA94.5
O), the characteristic such as high abrasion and be able to obtain increasingly extensive application and expansion in mould industry.Particularly on processing technology due to the restriction of its characteristic, due to the complex geometry of mould, the characteristics of moulding difficulty, so in the high-accuracy Mould Machining of digital cuttings, machining center (CNC) machined electrode and Electric Discharge Machining are all the master operations in the whole process of mould, are also the main composition parts of Mould Machining expense.
Traditional handicraft is with machining center, single electrode to be processed, carry out spark machined with single electrode pair mold and punching head again, each electric spark adds man-hour to mold and punching head, all need centering again, cause the mold and punching head precision that processes at last not high, and machining center is long to single electrode cycle process time.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of electrode of substrate of electrical spark working tool and mould, can be used for the processing to the sintered-carbide die drift with characteristics such as high strength, high rigidity, high abrasions.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of electrode of substrate of electrical spark working tool and mould
,On the copper-tungsten plate, once process simultaneously arranged side by side more than two, electrospark electrode processing curve that shape and structure is identical with machining center, consist of electrode of substrate; Described electrospark electrode processing curve is to make the electrospark electrode of reverse shape face by the curve form of the required processing of mold and punching head of machining center.
Described copper-tungsten plate employing W content is 60%～80% copper-tungsten plate.The good loss of electrodes conduct performance that wherein contains copper is little, therefore in roughing, electrode can adopt the red copper material; Adopting W content is the electrode of substrate that 60%～80% copper-tungsten plate is made, and has the characteristics such as high strength, high rigidity, high abrasion.
Described electrode of substrate is used for the sintered-carbide die drift is carried out the method for electric spark, comprising:
[1] on the copper-tungsten plate, with machining center arranged side by side more than two, the electrospark electrode processing curve that shape and structure is identical of time processing simultaneously once, consist of electrode of substrate; Described electrospark electrode processing curve is to make the electrospark electrode of reverse shape face by the curve form of the required processing of mold and punching head of machining center, guarantees the uniformity of each machining area on electrode of substrate fully;
[2] adopting electrode of substrate to carry out electrical spark working man-hour to the sintered-carbide die drift, after machining area of centering, after first discharge machining area machines, the curved surface of the processing mold drift that just can directly discharge after the side-play amount of using X-axis or Y-axis on electric spark shaping mill arrives second machining area; After second discharge machining area machines, use the side-play amount of X-axis or Y-axis to arrive the 3rd machining area on electric spark shaping mill, can directly discharge the again curved surface of processing mold drift is until the discharge machining area of electrode of substrate is completed the processing to whole mold and punching head curved surface.
The beneficial effects of the utility model: traditional method is with machining center, single electrode to be processed, process with single electrode pair mold and punching head again, each electric spark adds man-hour to mold and punching head, all need centering again, cause the mold and punching head precision that processes at last not high, and machining center is long to single electrode cycle process time.Arrange plural electrospark electrode processing curve on electrode of substrate of the present utility model, the disposable processing of available machining center processes; And in spark machined, after the curved surface of first machining area of centering electrode of substrate and the processing mold drift that discharges, the curved surface of processing mold drift can just can directly discharge after the side-play amount of using X-axis or Y-axis on electric spark shaping mill arrive second machining area, directly process after such centering, greatly saved process time, reduce consumption, improved die quality.
The inverted draw cut of in the past processing a mold and punching head needs CNC to mill 4 to 8 single electrodes, now at most only needs 2 with electrode of substrate.Every mold can be saved 5h, approximately 800 yuan of processing charges, and carry out electric machining by electrode of substrate, only need centering once, after a consumption of electrode was complete, directly being offset after electrode of substrate directly, processing got final product, very convenient, and can guarantee machining accuracy fully.
