Embodiment Construction

[0009] The base oil used for the lubricant is not particularly limited, as long as it is generally used as a base oil for metal working oil, and one or more components selected from mineral oil, synthetic oil, and grease may be used. As the mineral oil, those purified by using a conventional method in the lubricant production process of the petroleum purification industry can be used. Specifically, it includes the purification of crude oil by applying one or more processes such as solvent deasphaltization, solvent extraction, hydrogenolysis, solvent dewaxing, catalytic dewaxing, hydrogenation purification, sulfuric acid cleaning, and clay treatment. Those formed from the lubricant fraction obtained by atmospheric distillation or vacuum distillation.

[0010] Synthetic oils include, for example, poly-α-olefins, α-olefin copolymers, polybutenes, alkylbenzenes, polyoxyalkylene glycols, polyoxyalkylene glycol ethers, and Silicone oil. Specific examples of fats and oils include, for ex...

Abstract

The present invention provides a non-chlorine type lubricant in which a sulfur type extreme pressure additive, an organic zinc compound, a calcium type additive, and an ester compound are blended with a base oil for the lubricant, and having a kinetic viscosity from 5 to 50 mm<2> / s at 40 DEG C.

Description

Technical field [0001] The present invention relates to a non-chlorine type lubricant for pressure processing of metal materials. Specifically, it relates to a lubricant suitable for press working of a metal material to be used as a component such as an oil filter box, and a coating process is applied after the press working. In addition, it relates to a metal material press working method using the lubricant. Background technique [0002] In the pressure processing of metal materials, lubricants are generally applied between the tool and the metal material. This is to avoid the occurrence of cracks or seizures caused by insufficient lubrication during processing, or deterioration of mold processing life caused by increased friction. In shearing, which is a type of press processing, metal materials are manufactured by punching them using a die and a punching machine. Therefore, in a shearing process such as fine blanking (FB processing), a greater stress is generated between the ...
