Embodiment Construction

[0025] The specific method of the present invention will be further described below in conjunction with a processing example of a non-API threaded ring gauge of a certain specification.

[0026] see figure 1 Schematic of non-API threaded ring gauge stock shown. The material is 9Mn2V. After spheroidizing annealing, the blank is turned into a torus, and then quenched + shallow cooling + tempering + shallow cooling + tempering + aging heat treatment. The blank size is Ø305mm×Ø245mm×115mm.

[0027] see figure 2 Schematic diagram of the non-API threaded ring gauge thread construction shown. The internal thread taper of the part is 1°47´24, the pitch is 5.08mm, and the tooth depth is 1.575mm. The processing quality requirements of finished parts are: the thread tooth depth tolerance is 0.013mm, the tooth width tolerance is 0.025mm; the transition fillet dimensions of the thread guide surface and the bearing surface are R0.203mm and R0.762mm respectively, and the transition fille...

Abstract

The invention provides a non-API thread ring gauge electroplating super-hard abrasive molded grinding wheel matrix structure design method. According to the non-API thread ring gauge electroplating super-hard abrasive molded grinding wheel matrix structure design method, a super-hard abrasive molded grinding wheel and a grinding machining method are aimed at a non-API thread ring gauge part; by adoption of the super-hard abrasive molded grinding wheel and the optimized form-grinding machining method, the phenomenon of non-API thread ring gauge grinding burn can be avoided; the super-hard abrasive molded grinding wheel structure design comprises the grinding wheel matrix structure design and the grinding wheel work profile structure design; the super-hard abrasive molded grinding wheel matrix structure design comprises the grinding wheel matrix outline structure design, the grinding wheel groove factor design, the grinding wheel intermittent period design and the sand grooving parameter design; the grinding wheel intermittent period design is equivalent to the groove quantity design; and the super-hard abrasive molded grinding wheel work profile structure design comprises the grinding wheel tooth structure design and the corner critical position structure design. By combination of optimized super-hard abrasive grinding wheel form-grinding machining parameters, the problem about grinding burn in a non-API thread ring gauge rough grinding machining can be solved and the efficient grinding machining demand can be met.

Description

technical field [0001] The present invention relates to a non-API thread ring gauge electroplating superabrasive forming grinding wheel base structure design method, in particular to a non-API threading ring gauge electroplating superabrasive grinding wheel structure design and forming grinding process, which belongs to metal material grinding technology field. Background technique [0002] Non-API thread ring gauge is a special measuring tool specially used to comprehensively inspect the processing quality of non-API threaded joints (external threads) of oil well pipes. It has high requirements on the wear resistance, dimensional stability and processing accuracy of the workpiece. Temperature control, avoiding grinding burns, and obtaining high processing efficiency have high demands. The material of the parts is 9Mn2V, which contains high Mn elements and a small amount of V elements. After heat treatment, high hardness (HRC60~63) and good wear resistance can be obtained. ...
