Lubricant for forming stainless steel inner liner

Abstract

The invention discloses a lubricant for forming a stainless steel inner liner. The lubricant is prepared from, by mass, 3-7 parts of sulfurized olefin, 10-15 parts of sulfurized fatty acid ester, 3-7 parts of overbased calcium sulphonate, 11-14 parts of emulsifier and the balance chlorinated paraffin, wherein the emulsifier is prepared from, by mass, 6-8 parts of fatty alcohol-polyoxyethylene ether and 5-7 parts of petroleum sodium sulfonate, wherein the sulfurized fatty acid ester is used as an anti-wear agent at an extreme pressure, the chlorinated paraffin has excellent lubricating and extreme pressure resistance efficacies for stainless steel machining in a low-temperature area, the overbased calcium sulphonate plays a coordinating role in a system, and the fatty alcohol-polyoxyethylene ether and the petroleum sodium sulfonate contribute to emulsification in the system.

Description

technical field [0001] The invention relates to the field of lubricants, in particular to a stainless steel liner molding lubricant. Background technique [0002] In stainless steel stamping and drawing processing, stamping and drawing lubricants are necessary auxiliary products. The factors affecting the yield of stamping and drawing are very complicated, and the stamping and drawing lubricant is one of the important factors affecting the success or failure. Stamping and stretching lubricants have the characteristics of strong specialization and relatively narrow application range. [0003] In the forming process of the stainless steel liner, the extreme pressure requirements for lubrication are extremely high. At the same time, the interaction between the mold and the product and the plastic deformation of the stretched parts will generate a large amount of frictional heat and deformation heat. If the heat is not dissipated in the deformation area in time , will reduce t...

AI Technical Summary

Problems solved by technology

[0003] In the forming process of the stainless steel liner, the extreme pressure requirements for lubrication are extremely high. At the same time, the interaction between the mold and the product and the plastic deformation of the stretched parts will generate a large amount of frictional heat and deformation heat. If the heat is not dissipated in the deformation area in time , will reduce the viscosity of the lubricant and thin the lubricating film, resulting in direct contact between the mold and the product, resulting in scratches on the product surface, and in severe cases, the product will be torn and scrapped

[0004] The existing stainless steel stamping drawing oil uses high-viscosity lubricants, which often encounter problems such as wire drawing, cracking on the product surface, large die loss, and difficult cleaning of the workpiece
