Abstract
The invention discloses a lubricant combination for a cold spinning copper alloy tube. The lubricant combination is characterized by adopting 650SN base oil as base oil and cooperating with various additives including an oiliness agent, an extreme pressure agent, an anti-wear agent, an antioxidant, a friction modifier, a metal deactivator, a reinforcing agent, an auxiliary and an antirust agent. The lubricant combination disclosed by the invention is better in lubricating property, cooling property, wettability and anti-rust property, the strength of an oil film in a deformation zone is increased, the friction coefficients are reduced, and the oil film strength and thickness properties are kept stable; the adhesion is high, and the wear resistance, the viscosity-temperature property and the flushing property are good; the extreme pressure property is high, the wear of cold spinning equipment and the tube damage are reduced, the flow shear stress is smaller, the surface smoothness and the size and specification precision of the processed seamless steel tube are improved, and use and cleaning are convenient.
Description
Technical field
The invention belongs to metal working lubricant field, particularly cold spinning weldless steel tube lubricant compositions.
Background technology
In the cold spinning course of processing, except the friction between material, mould, on the contact surface because the speed of cold spinning improves, will occurrence temperature sharply rise.Heavy wear or sintering is there is, the effect thus requiring lubricant to play antifriction and prevent wearing and tearing, cool, lubricate in order to reduce in cold spinning process; Be improved cold spinning speed and section reduction rate simultaneously, to improve the seed output and quality of cold spinning processes, prevent the generation of the defect such as surface imperfection, scuffing, fold, bending, bias, crackle, metal press-in.
And the factor affecting cold spinning processing tube quality has usually: steel pipe character (hardness, degree of cleaning, condition of surface); And the material kind of relevant device and mould Tony; The adaptability of cold spinning lubricant.Due to the difference of mode, condition and range of product that cold spinning is processed, also there is difference to the requirement of lubricant.And lubricating method generally adopt immersion, brush, roll be stained with, traction or circulation etc.Therefore, cold spinning lubricant should meet many-sided requirements such as drawing process condition, industrial safety, economy, environmental friendliness, energy-conservation, reduction of discharging.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of tool good lubricating properties, cooling, wetting property, rust-preventing characteristic, increases oil film strength in distorted area, reduces frictional coefficient, keeps oil film strength and thickness stable performance; Adhesivity is strong, and resistance to abrasion, sticky warm nature, flushing performance are good; Extreme pressure property is strong, reduces wearing and tearing and the tubing damage of cold spinning equipment, has less flowing shear-stress, improve surface smoothness and the dimensions precision of processed weldless steel tube, the cold spinning weldless steel tube lubricant compositions with clearing up easy to use.
