Embodiment Construction

[0011] As shown in Fig. 1, the two-in-one processing method of the narrow series of thin-walled bearing rings means that two narrow series of thin-walled bearing ring blanks are processed and formed, and then cut and separated. The processing process is as follows: forging the preliminary formed blank raw material, first clamping and positioning at one end, turning the end face, inner diameter surface and the entire outer diameter surface of the other end and chamfering; then transposition clamping and positioning, turning the end face, inner diameter surface, inner diameter The chamfering treatment is carried out on the groove; after heat treatment, each forming surface is first finished; finally, it is cut along the cut (02), and the cut section is finished, and the aging treatment is carried out. Two bearing rings (01, 03) are thus produced simultaneously.

Abstract

A 2-in-1 machining way for a narrow thin-wall bearing ring. Wherein, a blank of two narrow thin-wall bearing ring is clamped integrally on a chuck of a lathe, the I.D., O.D., ends of the blank are turned, chamfered, then heat treatment is carried; after heat treatment, grinding is carried out; after that, the two bearing rings are cut apart. The specific machining procedures are: clamping and positioning one end of a forged and preliminarily formed blank, turning and chamfering the end face, ID, OD of another end; then changing another end for positioning and clamping, turning and chamfering the end face, ID, OD; carrying out heat treatment, grinding after heat treatment; cutting along the cutting interface, finishing the cut at the cutting interface; carrying out aging treatment. The invention solves the problem of warpage and deformation at hardening of narrow thin-wall bearing rings, improves the production efficiency and improves the utilization rate of raw materials.

Description

Technical field: [0001] The invention relates to the technical field of bearing design and manufacture, in particular to a two-in-one processing method for narrow series thin-walled bearing rings. Background technique: [0002] At present, for the narrow series of thin-walled bearing rings, the processing method of a single independent ring is generally used. Since the thin-walled bearing rings are easily warped and deformed during quenching during production, it affects the quality and accuracy of the subsequent processed products. Therefore, An auxiliary head is often added to the lower end of the processed thin-walled bearing ring blank, and the head is cut and removed after the initial finishing, thereby reducing deformation. Waste, production efficiency is also relatively low. Invention content: [0003] In order to overcome the defects existing in the prior art, the present invention provides a two-in-one processing method for narrow series thin-walled bearing rings...
