Description
Technical field
What the present invention relates to is a kind of lubricating oil, particularly a kind of micro-nano compound pull and stretch lubricating oil.Be used for the metalworking technology field.
Background technology
In the drawing and forming process of metal blank, can workpiece be shaped well, depend on forming technology, shaped material, mould structure and lubricating status, under the situation that the mould process design is determined, blank material is constant, have only by using rational lubricating system just can reduce friction, reduce die wear, improve workpiece surface quality.In the sheet-metal press working process, form so-called " bonding knurl " easily.The existence of " bonding knurl " will scratch workpiece surface, strengthen friction, the wearing and tearing of aggravation mould, the work-ing life of reducing mould.Overcome cold welding and sticky lump problem between metal blank and the die surface, need take suitable lubricant method.
Realize that one of lubricated mode is to adopt lubricating oil.Though liquid lubricant has easy to use, price is relatively cheap, cooling performance is advantage preferably, by adopting nanometer additive can improve its lubricity significantly, but, its lubricant effect is still comparatively limited, for some complex-shaped workpiece, uses the present liquid lubricant can't drawing and forming.Therefore can only be by means of another kind of lubricant---solid lubricant, wherein the most commonly used is plastics film.Under disruptive situation not, plastics film can separate blank and die surface fully, the rough peak on two surfaces can't directly be contacted adhere, and relatively sliding transferred in the lubricant film carry out, and obtains minimum frictional coefficient, thereby improves the sheet forming performance.In sheet forming process, use solid lubricant, because technological reason, be difficult for large-scale production, so practical application is subjected to certain restriction, especially be not suitable for high speed stamping processing.So when actual production, solid lubricant only just is used when the workpiece that some use conventional liq lubricants of pull and stretch are difficult to be shaped.
Find by literature search; Qiao Yulin, Xu Binshi, Ma Shining etc. are in " material protection " 2003 the 36th the 4th phases of volume; the antiwear and friction reduction property of micron borate additive " receive research " that the 17-19 page or leaf is delivered; this article has reported with ultrasonic emulsification and has disperseed that the prepared in reaction particle diameter is the spherical unformed micron borate additive of receiving of 50-250nm in microemulsion.Study its tribological property with four ball frictional testing machiness, when its weight percent in paraffinic based oil is 0.5%, wear scar diameter minimum, antifriction performance optimum.Its shortcoming is the distribution of sizes broad of additive particles, does not clearly embody the different functions of micron particle and nanoparticle.
Summary of the invention
The objective of the invention is to overcome deficiency of the prior art, a kind of micro-nano compound pull and stretch lubricating oil is provided, make the advantage of the lubricated and liquid lubrication of its integrated solid, to isolate mould and plate effectively, and utilize the physics chemical action of nanoparticle and newborn metallic surface, to improve the abrasion resistance of friction surface.
The present invention is achieved by the following technical solutions, each composition that the present invention comprises and shared weight percent thereof are: nanometer additive: 1～30%, micron additive: 1～30%, surplus is a base oil, described micron additive is the polyvinyl chloride powder, and described nanometer additive is nano-MgO or nanometer SiO
2Or nanometer Al
2O, described base oil are mineral oil or vegetables oil.
It is the polyvinyl chloride powder of 1～500 μ m that the micron additive adopts granularity.
Nanometer additive adopts the MgO of particle diameter less than 100nm, perhaps SiO
2, perhaps Al
2O
3
Base oil is the mineral oil of viscosity 10～500cp, perhaps the vegetables oil of viscosity 40cp.
The nanometer additive that in base oil, adds 1～30% weight percent, the micron additive of 1～30% weight percent.Definite employing balance weighing of weight percent mixes base oil, nanometer additive, micron additive then, disperses with paddling process, and the back is stablized in placement about half an hour stand-by.
Along with the additive granularity is reduced to nano level from micron order, additive is descending to the raising of drawing and forming lubricity, and is ascending again.During greater than the roughness of plate and mould, additive reduces friction significantly with the effect that is similar to " rolling bearing " in micron additive granularity, when it is reduced to less than the rough peak height, act on relatively poorly, and rough peak still can contact and adhere at this moment.And when it continues to be reduced to nanoscale, can on the plate rough peak, deposit and when forming tectum, can form good boundary lubrication again and good extreme pressure effect is arranged.Therefore adopt micron particle (yardstick is at 1～500 μ m) and nanoparticle (yardstick is less than 100nm) as composite additive, can obtain more good effect.In the middle of the process of sheet forming process, constantly there is fresh surface to produce in the distorted area, the micron additive can effectively separate the fresh surface of plate and contacting of die surface, the voussoir effect of Xing Chenging simultaneously can make nanoparticle be taken in the gap by base oil, combine with fresh surface rapidly, form the extreme boundary lubrication effect, thereby reduce the activity of fresh surface, avoid producing adhesion and wait the lubrication failure phenomenon.
The present invention has marked improvement, compare with common lubricating oil, adopt the prepared compounded lubricating oil of the present invention, in the plate shaping process, its maximum drawing force can reduce up to more than 20%, and frictional coefficient can reduce up to more than 26%, thereby reaches about 20% the work-ing life that can improve mould, significantly reduce the surfaceness of pull and stretch plate simultaneously, improve the surface quality of pull and stretch plate significantly.
