Abstract

A cold-rolling steel-plate punch stretch lube oil consists of motor oil 45-55wt%, castor oil 6-10wt%, soya oil 8-12wt%, barium mahogany acid 1-3wt%, lead naphthenate 1-3wt%, chlorinated paraffin 10-20wt%, butyl-octanol zinc salt phosphinothioyl 4-6wt% and poly-n-butyl vinyl ether 6-10wt% and bactericide 0.2-0.3wt%. The process is carried out by adding motor oil into reactor, heating to 90-100degree, adding into barium mahogany acid, lead naphthenate and chlorinated paraffin, agitating at 750-850/min for 1.5-2.5hrs, lowering temperature to 50-60degree, adding into castor oil, soya oil and bactericide, agitating for 0.5-1.5hrs, lowering to normal temperature, adding into butyl-octanol zinc salt phosphinothioyl and poly-n-butyl vinyl ether and agitating at 85-95/min for 1.5-2.5hrs. It has better oil-film continuity and adsorption and prevents punch work-piece from being scraped and corrosion.

Description

Cold-rolling steel-plate punch drawing lube oil and production method

Technical field:

The present invention relates to a kind of Sheet Metal Forming Technology with metalworking coolant and production method, especially a kind ofly prevent that scratching from appearring in the stamped workpieces surface, corrosion, can guarantee the cold-rolling steel-plate punch drawing lube oil and the production method of surface smoothness.

Background technology:

Punch process is called plate stamping again, is by mould sheet material to be exerted pressure, and makes it to separate or produce viscous deformation, thereby obtains the method for processing parts of certain size, shape and performance.In the punch process process, metallic substance produces plasticity shearing strain, between the shear surface that produces and mold work surface as the generation strong friction, then make localized hyperthermia and cause " seam " and adhesive wear, therefore need to use to have to reduce friction, the lubricant of the effect of cooling, in the hope of form withstand voltage heat-resisting and tough and tensile composite lubricating film in the metallic surface, new life's shear surface and die-face are separated, thereby reach the raising die life, the purpose of steady shear face surface quality.But, because relatively sliding is hard mold and softer processed blank in the punching stretch process, what viscous deformation took place is the whole blank that comprises surface in contact, the contact surface of blank and mould is very big again in addition, therefore is difficult to form on whole surface of friction successive hydrodynamic lubrication film.At present, the lubricating oil that is applied to cold-rolling steel-plate punch drawing is exactly because of the existing problems of choosing in effective constituent and proportioning, cause the punch of lubricating oil in press tool, between die surface and the workpiece material contact surface formed oil film be difficult to continuous and adsorptivity relatively poor, under powerful stamping press extruding, formed oil film is damaged easily, make between sheet material part and the mould and may be in dry condition, the stamped workpieces surface is scratched easily, and the easy oxidation of plate surface and corrosion (pitting corrosion and spot erosion etc.) occurs, smooth finish, luminance brightness sharply reduces, give the phosphatization in road, back, spraying coating process makes troubles, and has had a strong impact on the visual appearance of product; Also aggravate the wearing and tearing to mould simultaneously, influence the work-ing life of mould, production cost increasing, production cycle are prolonged, manufacturer suffers bigger financial loss.

Summary of the invention:

The present invention is in order to solve the above-mentioned technical problem of existing in prior technology, a kind of oil film continuity and excellent adsorption to be provided, can prevent that scratching from appearring in the stamped workpieces surface, corrosion, can guaranteeing the cold-rolling steel-plate punch drawing lube oil and the production method of surface smoothness.

Technical solution of the present invention is: a kind of cold-rolling steel-plate punch drawing lube oil, and its feed composition and weight percent are as follows:

Machinery oil 45～55%

Viscotrol C 6～10%

Soybean oil 8～12%

Lead naphthenate 1～3%

Barium mahogany sulfonate 1～3%

Clorafin 10～20%

Sulphur phosphorus fourth octanol zinc salt 4～6%

Poly-normal-butyl Vinyl Ether 6～10%

Sterilant 0.2～0.3%.

Optimum feed stock component and weight percent are as follows:

Machinery oil 49.75%

Viscotrol C 8%

Soybean oil 10%

Lead naphthenate 2%

Barium mahogany sulfonate 2%

Clorafin 15%

Sulphur phosphorus fourth octanol zinc salt 5%

Poly-normal-butyl Vinyl Ether 8%

Sterilant 0.25%.

A kind of production method of cold-rolling steel-plate punch drawing lube oil is characterized in that having the following steps:

A. be that 45～55% machinery oil adds in the reactor with weight percent, be heated to 90～100 ℃, start agitator, rotating speed is 750～850 rev/mins, the weight percent that adds successively is that 1～3% barium mahogany sulfonate, weight percent are that 1～3% lead naphthenate, weight percent are 10～20% clorafins then, and continuously stirring 1.5～2.5h, cool to 50～60 ℃ then;

B. add weight percent more successively and be 6～10% Viscotrol C, weight percent and be 8～12% soybean oil, weight percent and be 0.2～0.3% sterilant, continue to stir 0.5～1.5h, reduce to normal temperature;

C. add weight percent successively and be 4～6% sulphur phosphorus fourth octanol zinc salt, weight percent and be 6～10% poly-normal-butyl Vinyl Ether, stir 1.5～2.5h by 85～95 rev/mins stirring velocitys.

Oiliness improver of the present invention mainly is lipid acid and the alcohols organic compound that long carbochain end has active group, the active group and the metallic surface of these organic compound react, in punching course, just can make chemical transformation takes place himself, generate certain thickness protective membrane at the surface in contact of punching press by the high temperature that produces on the frictional interface; Extreme pressure agent then adopts acidproof compound (as lead naphthenate) with bigger absorption residual acid etc., the cold rolling laminar surface generation chemisorption that can be covered with passive film, its active group once in conjunction with being adsorbed on cold rolling laminar surface, strengthens the adsorptive power of protective membrane by strong; And lipid acid and cold rolling laminar surface bonded product are zinc soaps, and the hydrocarbon chain of these soaps partly has the characteristic on arranged vertical and cold rolling surface, thus the film that formation rule is arranged; The rust-preventive agent that is added (barium mahogany sulfonate), inhibiter (sulphur phosphorus fourth octanol zinc salt etc.) can effectively stop workpiece surface oxidized, and special feed composition and proportioning combination make the present invention compare with prior art, have following advantage:

1. the chemisorption of lubricant film and physical adsorbability are good, between stamped workpieces and mould, form evenly continuously, complete liquid medium film, the formed lubricant film absorption in surface firmly, the heatproof resistance to compression, be difficult in the punching stretch process destroyed, make and have good oilness between stamped workpieces and the mould, prevent stamped workpieces surface sintering, seam and being scratched, produce corrosion etc., guarantee that workpiece surface has standard compliant smooth finish, wearing and tearing have been reduced simultaneously to mould, prolong the work-ing life of mould, can reduce production cost of products, shorten the production cycle, significantly improve the production efficiency and the economic benefit of enterprise;

2. the present invention is the even thickness oily matter of sundown, is added with sterilant, and is not perishable, uses 3 months, and nontoxic ordorless smell is beneficial to environmental protection, can not influence health of operators.
