Lubricating oil for stamping machinery

Abstract

The invention discloses lubricating oil for stamping machinery. The lubricating oil consists of the following raw materials in parts by weight: 100-300 parts of III-type basic oil, 500-800 parts of PAO (Poly Alpha Olefin) synthetic oil, 50-80 parts of mineral oil, 10-20 parts of animal and plant grease, 1-5 parts of zinc dialkylphosphorodithiloate, 5-7 parts of petroleum sulfonate, 1-6 parts of benzoic acid, 3-5 parts of an T2XX anti-oxidation preservative, 1-3 parts of polymethacrylate, 1-2 parts of a PPD (Pour Point Depressant) improver and 1-5 parts of triethyl-hexyl phosphoric acid. According to the lubricating oil for stamping machinery, the synthetic oil is adopted as basic oil, the mineral oil and the grease oil are added, the III-type basic oil is adopted as neutralizing oil, and additives are added, therefore, the volatilization time of the lubricating oil can be reasonably controlled, the lubrication and cooling effect of the stamping process can be improved, environment pollution is eliminated, and the production environments are improved.

Description

technical field [0001] The invention relates to a lubricating oil for stamping machinery. Background technique [0002] At present, most stamping oils on the market are composed of petroleum extracts. Since they are extracted from petroleum, they have certain paraffin components. Paraffin wax cannot be volatilized in the application, because it is not allowed to contain paraffin components when used in refrigeration compressor motors, so , cannot be used when stamping silicon steel sheets. In addition, some stamping oils volatilize too fast, which will cause serious pollution to the environment of the production site, and due to too fast volatilization, when the high-speed die is punching, the stress of the punching is concentrated, the punching burrs are large, and the local punching The coating will be damaged, which has a great impact on the performance of the motor, especially the efficiency of the motor.
