Description

Technical Field

[0001] The utility model relates to the technical field of bearing forging, in particular to an automatic coolant spraying device for bearing forging. Background Technique

[0002] A bearing is an important component in contemporary mechanical equipment. Its main function is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotational accuracy. When manufacturing bearings, forging is required. Forging is a processing method that uses forging machinery to apply pressure to metal billets, causing them to undergo plastic deformation to obtain forgings with certain mechanical properties, certain shapes, and sizes, which is one of the two major components of forging. Through forging, defects such as as-cast porosity generated during the smelting process of metals can be eliminated, and the microstructure can be optimized. At the same time, due to the preservation of the complete metal streamline, the mechanical properties of forgings are generally better than those of castings made of the same material. For important parts with high loads and severe working conditions in related machinery, except for those with relatively simple shapes that can use rolled plates, profiles, or welded parts, forgings are mostly used.

[0003] During the forging of bearings in the prior art, a large amount of heat is generated by the forging head. If the heat is not dissipated in time, it will affect the strength of the forging head, thereby affecting the service life of the forging head. Therefore, we propose an automatic coolant spraying device for bearing forging to solve the above-mentioned problems. Content of the Utility Model
