Abstract

The invention discloses a bearing roller cold forging production process. A bearing roller, especially a conical roller, with a small diameter (phi is smaller than 29 mm) is formed by upsetting with acold header, and the bearing roller, especially the conical roller, with a large diameter (phi is larger than 30 mm) is usually machined by a lathe. The structure of the bearing roller formed throughcutting is not compact enough, a metal flow line is cut, and the material utilization rate is low. In large mechanical bearings of wind power generation, mining machinery and the like, once the quality of the bearing roller is not qualified, the replacement of the bearing roller after being installed and used is time-consuming, labor-consuming, and extremely high in cost. The bearing roller coldforging production process has the advantages that no flash exists in the precision forging process, edge trimming is not needed, a forging stock does not need to be cut, and grinding can be conductedafter direct 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...
