Description

The lubricant of punching press lead and lead alloy material

Technical field

The invention belongs to the field of lubricant of non-ferrous metals processing Sheet Metal Forming Technology lubricant, especially punching press lead and lead alloy material.

Background technology

Lead is bluish silvery white heavy metal, toxic, is a kind of malleable main group metal.Fusing point 327.5 DEG C, boiling point 1740 DEG C, density 11.34g/cm ³, hardness 1.5, quality is soft, and tensile strength is little.Lead is easy to get rusty---oxidation.Lead is often grizzly, be exactly due to it in atmosphere, very easily become the plumbous oxide of grey black by the dioxygen oxidation in air, make its argenteous gloss gradually become intensely dark.The important use of metallic lead manufactures store battery.The resistance to deformation of lead alloy is little, and ingot casting does not need the technique such as heating and available rolling, extruding to make sheet material, band, tubing, bar and wire rod, and does not need process annealing process.Because the shearing of lead alloy, creep strength are low, under certain load and rolling shear effect, lead alloy is easily deformable and thinningly become foil-like; And the self-lubricity of lead alloy, running-in ability and damping property are good, noise is little, because of but good bearing metal.Graphite metal and tinhase bearing metals are referred to as Babbitt metal, can make the Locomotive Bearing of high-load.

The feature of punching production technique is: use simple mechanical means, goes out complicated product by Mould Machining; Part accuracy is high, and interchangeability is good, and intensity is high, good rigidly, lightweight part usually no longer to need a large amount of mechanical workout just can obtain; Cheap sheet material and band can be utilized, be conducive to saving metallic substance; Do not need heating, production efficiency is high, and product is with low cost; Be conducive to realizing mechanize and automatization, alleviate the labour intensity of workman and improve working conditions.Pressed part is widely used in the aspects such as motor, electrical equipment, household electrical appliance, haberdashery and hardware vessel and aerospace communications and transportation.

Plumbous and the lead alloy material of punching press is plumbous and one of advanced production method in lead alloy formed machining, it is on the basis of metal plastic deformation, mould and press machine facility is utilized to carry out press working to slab, make it produce viscous deformation, thus obtain the product of definite shape, size and performance.In punching course, there are crackle or seizing (wrinkle) to prevent lead and lead alloy material, guarantee tangent plane smooth bright and clean, extend life-span of rushing tool and keep sword degree simultaneously, just need the lubricant with good degreasing, weldability, oilness, cooling, friction reduction characteristics, sliding friction, antioxidant.

Summary of the invention

The technical problem to be solved in the present invention is to provide the lubricant of the plumbous and lead alloy material of a kind of punching press, this lubricant have low to the adsorptivity of plumbous and lead alloy material and good penetrability, viscosity, have good oilness and cooling, friction reduction characteristics, sliding friction, anti-embroidery, crackle or seizing can be prevented.

The present invention solves the problems of the technologies described above by following technical scheme: adopt oil based on No. 15 total loss system oil, coordinate multiple composite additive, its component and mass percent are:

Component	Content (mass percent)
		Base oil	Surplus
Oiliness improver	10.0%～15.0%
		Anti-wear agent	5.0%～8.0%
Oxidation inhibitor	0.8%～1.2%
		Kilfoam	0.005%～0.01%
Friction improver	4.0%～6.0%
		Antioxidant preservative	0.5%～1.0%

Base oil is No. 15 total loss system oil.

Oiliness improver is hydrogenated cottonseed oil.

Anti-wear agent is the Zinic stearas of mass ratio 50% ~ 40% and the lipid acid compound of 50% ~ 60%.

Oxidation inhibitor is the 2,6 ditertiary butyl p cresol of mass ratio 50% ~ 40% and the dinonyldiphenylamine compound of 50% ~ 60%.

Kilfoam is dimethyl silicone oil.

Friction improver is No. 2 liquid petroleums.

Antioxidant preservative is the two octyl group basic zinc salt of sulphur phosphorus.

The lubricant of impact extrusion lead of the present invention and lead alloy material, have the adsorptivity to plumbous and lead alloy material and good penetrability, viscosity is low, has good oilness and cooling, friction reduction characteristics, sliding friction, anti-embroidery are good, can prevent crackle or seizing.
