Abstract
The invention discloses a lubricant composition for a cold spinning aluminum alloy pipe. The lubricant composition adopts No.68 total loss system oil as base oil, and is cooperated with various additives, wherein the additives comprise an oiliness agent, an antioxidant, an extreme-pressure agent, an antiwear agent, a friction improver, an auxiliary and a strengthening agent. The lubricant composition disclosed by the invention is high in extreme-pressure performance and invariability performance, and improves the technological lubrication performance, the cooling performance and the cleaning performance; the strength of an oil film in a deformation zone is enhanced, the compression resistance of the spinning pipe materials is improved, the pressure distribution is uniform, bursting force is resisted, and the accuracy of cross dimensions is improved, so that the metal flows uniformly, the friction coefficient is reduced, and the possibilities of pipe material adhesion and surface damage are low; chemical compositions and performance are stable, metal and molds are not corroded, and the lubricant composition is non-toxic and has no pungent smell.
Description
Technical field
The invention belongs to metal working lubricant field, particularly cold spinning aluminium-alloy pipe lubricant compositions.
Background technology
It is high that aluminum and aluminum alloy mateial has specific tenacity, good heat conduction and electroconductibility, reflective is strong, plasticity good, good moldability, without advantages such as low temperature brittleness, be a kind of nonferrous materials with excellent comprehensive performance, be widely used in the fields such as modern automobile industry, space industry, telecommunications industry, computer industry.Along with the high speed development of China's modern industry and the raising of processing technology level, people get more and more to the demand of Al and Alalloy, and performance requriements is also more and more higher.
Strengthen the structurally-modified or Research on Surface Modification of Al and Alalloy, seeking new technologies and improve its application performance, is the problem that people pay close attention to.Cold spinning technology is the more complete processing of Recent study.The development of cold spinning technology mainly develops high value-added product, and its pipe fitting quality of producing is high, and can bear large impact force action, its mechanical property such as plasticity, toughness is better; Under the prerequisite ensureing detail design intensity, alleviate equipment and device own wt; Save metallic substance; Reduce production cost, production efficiency is high.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind ofly has good extreme pressure property and stability performance; Improve technological lubrication, cooling, cleaning performance, increase oil film strength in distorted area, the carrying capacity, the pressure distribution that improve spinning tubing are even, resistance to fracture power, improves cross dimensions tolerance range, makes metal flow even, reduce frictional coefficient, tubing adhesion and surface damage phenomenon not easily occur; Chemical constitution and stable performance, to metal and mould corrosion-free, nontoxicity, the cold spinning aluminium-alloy pipe lubricant compositions had no irritating odor.
The present invention adopts following technical scheme to solve the problems of the technologies described above:
Cold spinning aluminium-alloy pipe lubricant compositions, adopt oil based on No. 68 total loss system oil, coordinate multiple additives, its each component and mass percent thereof are:
| Component | Mass percent content |
| Base oil | Surplus |
| Oiliness improver | 5.0％～8.0％ |
| Oxidation inhibitor | 0.6％～1.0％ |
| Extreme pressure agent | 3.0％～5.0％ |

| Strengthening agent | 0.3％～0.5％ |
Oiliness improver is butter.
Oxidation inhibitor is the dinonyldiphenylamine T558 compound of mixing many rings phenol Hitec4782 and 50% of mass ratio 50%.
Extreme pressure agent is acid phosphonous acid dibutylester.
Anti-wear agent is sulfide isobutene.
Friction improver is glycerol monoleate.
Auxiliary agent is 124 Triazole derivative.
Strengthening agent is dialkyldithiocarbamacompositions tungsten.
Remarkable advantage of the present invention has: have good extreme pressure property and stability performance; Improve technological lubrication, cooling, cleaning performance, increase oil film strength in distorted area, the carrying capacity, the pressure distribution that improve spinning tubing are even, resistance to fracture power, improves cross dimensions tolerance range, makes metal flow even, reduce frictional coefficient, tubing adhesion and surface damage phenomenon not easily occur; Chemical constitution and stable performance, to metal and mould corrosion-free, nontoxicity, has no irritating odor.
