Abstract

The invention discloses a cold forging production process of a bearing roller. Bearing rollers, especially tapered rollers with small diameters (below Φ29 mm) are formed by heading with cold heading machines; while large diameters (above Φ30 mm) are mostly processed by lathe cutting. The structure of the cut bearing roller is not tight enough, the metal flow line is cut, and the material utilization rate is low. In wind power generation, mining machinery and other large-scale mechanical bearings, once the quality of the bearing rollers is not satisfactory, it will be time-consuming and costly to replace them after installation and use. The invention has the advantages of no flash and edge trimming in precision forging, and the forging billet does not need to be cut, and can be ground directly after quenching.

Description

technical field [0001] The invention relates to a cold forging production process of a bearing roller. Background technique [0002] Bearing rollers, especially tapered rollers with small diameters (below Φ29 mm) are formed by heading with cold heading machines; while large diameters (above Φ30 mm) are mostly processed by lathe cutting. The structure of the cut bearing roller is not tight enough, the metal flow line is cut, and the material utilization rate is low. In wind power generation, mining machinery and other large-scale mechanical bearings, once the quality of the bearing rollers is not satisfactory, it will be time-consuming and costly to replace them after installation and use. Contents of the invention [0003] Purpose of the invention: The purpose of the invention is to solve the deficiencies in the prior art, and provide a bearing roller cold forging production process, in which the cut bearing steel bar is forged by multi-station divisions of a press at roo...
