Embodiment Construction

[0012] Such as figure 1 As shown in , the two-in-one processing method of the narrow series of thin-walled bearing rings refers to two narrow series of thin-walled bearing ring blanks that are processed and formed, and then cut and separated. The processing process is as follows: two narrow series of thin-walled bearing rings are forged together into a rough blank, and the blank raw material that is initially formed by forging is first clamped and positioned at one end during turning, and the end face, inner diameter surface and the entire outer diameter of the other end are turned. The surface is chamfered; then the positioning is transposed, the end face, the inner diameter surface, and the groove of the inner diameter cutout are turned and chamfered; after heat treatment, each forming surface is firstly finished; finally, the groove along the inner diameter is cut ( 02) cut off, and the cut section is finished, and the aging treatment is carried out. Two bearing rings (01,...

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 in the prior art, the invention provides a two-in-one processing method for narrow series thin-walled bearing rings. It adopts the ...
