Abstract

The invention relates to an angular contact ball bearing outer ring forge piece profiling plate and a method for machining an outer ring forge piece, in particular to an angular contact ball bearing 7300BTN-series outer ring forge piece profiling plate and an outer ring forge piece machining method, and aims to solve the problems of raw material waste, high machining process difficulty and low production efficiency during machining of 7300BTN-series outer ring original forge pieces. According to the profiling plate, an arc-shaped notch is formed in the middle of the profiling plate, the left side and the right side of the arc-shaped notch are planes, and a plurality of through holes are formed in the profiling plate. The method for machining the outer ring forge piece through the angular contact ball bearing outer ring forge piece profiling plate comprises the following main steps that thirdly, a base surface and an inner hole are roughly turned; fourthly, a non-base surface, an outerdiameter and an inner diameter are finely turned, and outer ditches and outer slope steps are roughly turned; fifthly, the base surface and the outer diameter are finely turned; sixthly, the non-basesurface is softly ground; seventhly, the outer diameter is softly ground; eighthly, the outer ditches are finely turned; ninthly, the outer slope steps are finely turned; tenthly, chamfers are turned;and eleventhly, heat transfer treatment is conducted. The invention relates to the field of bearing machining.

Description

technical field [0001] The invention relates to a profiling plate and a processing method for an outer ring forging of an angular contact ball bearing, in particular to a profiling plate and a processing method for an outer ring forging of an angular contact ball bearing 7300BTN series. Background technique [0002] The 7300BTN series of angular contact ball bearings produced in the prior art have large batches and good market sales, but there have been many problems in the processing of the outer ring of the bearing, such as waste of raw materials during processing, difficult processing procedures, and low production efficiency. For the above problems, after research, it is necessary to improve the design of this series of product process regulations. The groove rolling process of deep groove ball bearings can be used for reference, and the outer and inner diameters of the fine-turned angular contact ball bearings and the outer grooves of the rough-turned angular contact bal...
