Description

Technical Field

[0001] The utility model relates to the field of bearing processing, in particular to a hole expanding device for a bearing ring. Background Art

[0002] During the processing of bearing rings, they are usually first processed into a circular ring with a smaller diameter and a thicker wall. Then, the circular ring is extruded through a ring rolling machine to be processed into a bearing ring with a larger diameter and a smaller wall thickness.

[0003] For example, patent document CN117772971A discloses a bearing ring reaming device. During the workpiece processing process, the workpiece is sequentially placed on a limiting column. The limiting column then drives the workpiece to abut against a rolling column for processing. After processing is completed, the workpiece is separated from the rolling column and unloaded. The workpiece processing can be carried out continuously, thereby improving the processing efficiency of the workpiece. However, during the reaming process, the annular workpiece is easily rolled in the radial direction, which causes metal expansion in the tangential and axial directions. The expansion in the tangential direction is necessary for reaming, while the expansion in the axial direction is useless and affects the yield rate. The axial expansion of this device cannot be controlled. Utility Model Content
