Problems solved by technology

[0007] Friction, high temperature, oxidation and other phenomena will inevitably occur in the production process of the cold rolling machine. The traditional cold rolling oil expansion uses water-based lubricants, but the water-based lubricants have problems of insufficient extreme pressure and environmental pollution. And it will cause the surface of the workpiece to be rough and cause quality problems, and it will shorten the service life of the cold rolling machine

Abstract

The invention provides a special cold ring rolling oil composition for bearing processing, wherein the special cold ring rolling oil composition comprises, by weight, 0.1-10% of an anti-oxidation anti-corrosion agent, 0.01-1.0% of an anti-rust agent, 5.0-50% of an extreme pressure anti-wear agent, and the balance of mineral base oil, and further comprises an antifoaming agent accounting for 0.001-0.1% of the total mass of the previous components. According to the present invention, the special cold ring rolling oil composition has advantages of good extreme pressure abrasion resistance, good oxidation resistance and good cooling property, and can be used for the lubrication of cold ring rolling equipment for producing bearing rings.

Description

technical field [0001] The invention relates to a lubricating oil composition, in particular to a special cold rolling oil spreading oil for bearing processing with excellent anti-wear performance, excellent anti-oxidation performance and cooling performance. Background technique [0002] Processing ring parts by rolling at room temperature is another type of rolling processing. In recent years, my country's bearing industry has begun to use cold rolling to process bearing rings. The difference between it and parts such as cold-rolled screw or gear is that the blank of the bearing ring is cold-rolled between the forming roll and the core roll, and the section is reduced and the diameter of the workpiece is enlarged. In order to distinguish it from the cold rolling processing of parts such as bolts and gears, we call the cold rolling processing of ring parts such as bearing rings cold rolling processing, and the equipment used for cold rolling processing is called cold rolli...
