Abstract

The invention discloses a warm forging production process of a bearing roller. A warm forging production process for bearing rollers, the specific steps are as follows: a) feed the steel bar into the heating furnace; b) spray lubricant on the steel bar and continue heating; c) carry out multiple Station forging; d) Forging surface quality inspection; e) Grinding after quenching; f) Entering the inspection line for inspection. The invention has the advantages of no flash and edge trimming in precise forging, and the forging blank does not need to be cut, and can be ground directly after quenching.

Description

Technical field [0001] The present invention relates to a bearing roller water forging production process. Background technique [0002] Bearings, especially taper columns, small diameter (φ29 mm or less) is used to apply cold heading machines; and large diameter (φ30 mm or more) is multiferic. The bearing roller tissue made of cutting is not tight, the metal flow line is cut, and the material utilization rate is low. In large mechanical bearings such as wind power, mine machinery, etc., once the bearing rollers are not too much, after installation, replacement, time-consuming, cost is extremely high. Inventive content [0003] Apparatus: It is an object of the present invention to solve the deficiencies in the prior art, providing a bearing roller water forging production process, which will heat the cut bearing steel bar with a temperature range of low temperature 700-800 ° C, and more The stationary segment forging, in addition to the rearward procedure is required to grind t...
