Abstract
The utility model relates to an electrode for machining internal threads on hard alloy materials, which belongs to the field of machining tools and comprises an electrode body. The electrode is characterized in that a threaded rod is arranged at the front of the electrode body and is in a screw-tap-shaped structure, and a chip groove is machined on the threaded rod. The electrode for machining internal threads on hard alloy materials is simple in structure, low in machining cost and high in machining precision.
Description
Technical field
The utility model relates to machining and uses the cutter field, at length say be a kind of on Hardmetal materials machining internal thread use electrode.
Background technology
As everyone knows, present Digit Control Machine Tool mostly adopts the high speed roughing feed to improve working (machining) efficiency, and the knife bar intensity of some minor diameter steels can't meet the demands, uses Hardmetal materials to make knife bar, on intensity, has guaranteed the service life and the working (machining) efficiency of cutter.Wherein a lot of knife bars adopt screw thread to be connected with handle of a knife.Because Hardmetal materials hardness is high, screw thread is difficult to processing, and present method is through carrying out sintering behind the mould molding, because the influence of various factors such as sintering warpage, accuracy of thread is very low, is difficult to reach the designing requirement of high precision cutting tools.Can't use method for grinding to process for the higher minor diameter internal thread of required precision, abroad have now and adopt the ultrasonic vibration technology to come processing rigid alloy internal thread, but lathe and consumptive material cost an arm and a leg, cost is very high.
Summary of the invention
The purpose of the utility model just is to overcome the deficiency of prior art, provide a kind of on Hardmetal materials machining internal thread use electrode, simple in structure, processing cost is low, machining accuracy is high.
The utility model solves the technical scheme that its technical problem adopted: a kind of on Hardmetal materials machining internal thread use electrode, be provided with electrode, the front portion that it is characterized in that electrode is a threaded rod, threaded rod is a screw tap shape structure, is processed with chip area on the threaded rod.
The beneficial effect of the utility model is, and is simple in structure, and processing cost is low, it is high to add the formula precision.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the A-A cutaway view of figure.
1. electrodes among the figure, 2. threaded rod, 3. chip area.
The specific embodiment
In Fig. 1, Fig. 2, the utility model is provided with electrode 1, and the front portion of electrode 1 is a threaded rod 2, and threaded rod 2 is a screw tap shape structure, is processed with chip area 3 on the threaded rod 2.
The utility model threaded rod 2 is made the screw tap shape, and the footpath is less than the footpath certain size in the processed thread standard in tooth form, and all the other sizes comprise that tooth form, tooth form angle etc. make by processed thread standard fully, and process chip area, are beneficial to improve working (machining) efficiency; During machining internal thread, workpiece is fixed on the workbench, electrode is installed on the C axle of lathe, adopts electrode to turn round along axis, simultaneously by the lead feeding that links vertically, adopts man-hour translation to come diameter dimension is compensated adding; Processing takes the accurately machined way of one or many to reach designing requirement according to required precision after removing most materials.
Claims (1)
