Abstract

The invention discloses a bearing roller warm forging production technology. The bearing roller warm forging production technology comprises the following specific steps that (a), feeding is carried out, and steel bars are fed into a heating furnace; (b), a lubricant is sprayed on the steel bars, and continuous heating is carried out; (c), multi-station forging is carried out at 700-800 DEG C; (d), the forging surface quality is detected; (e), grinding process is carried out after quenching; and (f), detection is carried out entering a detection line. The bearing roller warm forging productiontechnology has the advantages of precision forging without trimming and scrap edge, forging stock without cutting, and grinding process after direct quenching.

Description

technical field [0001] The invention relates to a warm 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 mechanical bearings, at the same time, once the quality of the bearing rollers is not satisfactory, after installation and use, it is time-consuming and labor-intensive to replace them, and the cost is extremely high. 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 warm forging production process. The cut bearing steel bar is heated at a ...
