Abstract

A galvanized steel plate punch stretch lube oil consists of motor oil 45-55wt%, castor oil 2-4wt%, soya oil 25-35wt%, mersolates 0.5-1.5wt%, zinc naphthenate 0.5-1.5wt%, triethyl phosphate 2-4wt%, chlorinated paraffin 3-5wt%, butyl-octanol zinc salt phosphinothioyl 2-4wt%, poly-n-butyl vinyl ether 4-6wt% and bactericide 0.2-0.3wt%. The process is carried out by adding motor oil into reactor, heating to 90-100degree, agitating at 750-850/min, adding into mersolates, zinc naphthenate, chlorinated paraffin and triethyl phosphate successively, agitating 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 75-85/min and agitating 1.5-2.5hrs. It has better oil-film continuity and adsorption and prevents punch work-piece from being scraped and corrosion.

Description

Zinc-coated steel-plated 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 Zinc-coated steel-plated 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 Zinc-coated steel-plated 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 Zinc-coated steel-plated punch drawing lube oil and the production method of surface smoothness.

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

A kind of Zinc-coated steel-plated punch drawing lube oil, its feed composition and weight percent are as follows:

A kind of production method of Zinc-coated steel-plated 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 0.5～1.5% petroleum sodium sulfonate, weight percent are that 0.5～1.5% zinc naphthenate, weight percent are that 3～5% clorafin, weight percent are 2～4% triethyl phosphates then, and continuously stirring 1.5～2.5h, cool to 50～60 ℃ then;

B. add weight percent more successively and be 2～4% Viscotrol C, weight percent and be 25～35% 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 2～4% sulphur phosphorus fourth octanol zinc salt, weight percent and be 4～6% poly-normal-butyl Vinyl Ether, stir 1.5～2.5h by 75～85 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; Ultrafine solids stable compound (as triethyl phosphate) is then adopted in the extreme pressure combination, and interpolation has the acidproof compound (as zinc naphthenate) of bigger absorption residual acid etc., can chemisorption take place with the zinc coating surface that passive film is covered with, its active group once in conjunction with being adsorbed on the zinc coating surface, strengthens the adsorptive power of protective membrane by strong; And the product of lipid acid and zinc coating surface bonding is a zinc soap, and the hydrocarbon chain of these soaps partly has the characteristic of arranged vertical and galvanizing surface, thus the film that formation rule is arranged; The rust-preventive agent that is added (petroleum sodium 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.
