Description
Technical field
The invention belongs to non-ferrous metals processing field of lubricant, particularly a kind of composition of Aluminum-aluminum alloy heat forged lubricant.
Background technology
Forging, divides the multiple working methods such as flat-die forging, at a high speed forging, roll forging and precision die forging by processing mode; Cold forging, warm forging and forge hot etc. can be divided into again with the moulding process temperature condition of material.The object of forging mainly improves the degree of irregularity of base material interalloy compound distribution, thus improves the mechanical property of forging.Forging processing is defined as: compression or jumping-up and in closed mould, make crude green body shaping and unnecessary metal is entered the process of burr groove in open die.It should be noted that, forging process can carry out under impact (hammering) condition, and also can carry out under (pressing machine forging) condition at a slow speed, processing temperature can be room temperature or high temperature
The effect of forging lubricant: forging can at room temperature be carried out, and also can carry out under middle temperature or high temperature, mould can use open die, die forging mould or closed mould.It is a kind of intermittent type course of processing.The effect applying lubricant has: reduce forging load, promotes that metal flows in a mold, prevents mould stuck, reduce die wear, as the thermal boundary between workpiece and mould, is convenient to the de-forging of workpiece.
The characteristic that forging lubricant should possess: moistening metallic surface equably, in case local is unlubricated; There is no residue, there is certain cooling effect; Can not mould be corroded, but protection Tu layer should be provided to mould, wetting property, good adhesion; Be suitable for autofeed or spray Tu feed; Free from environmental pollution, waste liquid easily processes, and does not form harmful material; Excellent storage stability, is mixed into hydraulic efficiency oil and is easily separated; Concentrated shape lubricant can be diluted to the forging process being satisfied with different lubricating requirement; Price economy is reasonable.In addition, the lubricant that forging process is used has also having of liquid state solid-state.
Many factors is depended in the selection of forging lubricant, wherein important consideration forging temperature, Forging Equipment Speed, the complexity of distortion and mold surface finish etc.
In the forge hot course of processing, service temperature and die temperature are all very high, and conventional liquid lubricant is easy to volatilization.The hot forging temperature of such as aluminium alloy also has 400 DEG C; And the hot forging temperature of high-melting-point low-alloy steel grade can reach more than 1650 DEG C.Therefore, lubricant used containing solids, namely adds solid lubricant usually in oil base or water base lubricant.As graphite, molybdenumdisulphide and other solid lubricants.Reduce temperature and can increase the mold use life-span, particularly keeping mould, that large temperature variation does not occur is very important, because significantly the changing caused cool-hot fatigue and can cause burn failure of die temperature.Such as: when forging nickel-base alloy, high-meltiing alloy and titanium workpiece, also often can adopt glass coating, lubricate on the one hand, stops workpiece oxidation on the other hand.
Cold forging, room temperature forges lubricant used based on oil lubricant.If flow of metal rate is less, as when cold-heading or press forging, available high viscosity fluid; If impact velocity is very high, as high-voltage high-speed forging, then the low viscous lubricant of Bian.Cold Forging has very high contact pressure, usually adopts the lubricating system of chemical reaction film.Cold forging lubricant Main Function used reduces frictional wear, prevents metallic surface from occurring concave point or sintering.Under comparatively harsh cold forging condition, the lubricant of tool extreme pressure property must be adopted, or adopt compound to cover the lubricating process of film forming.Due in Cold Forging process, deformation heat and heat of friction can be produced; Processing repeatedly carries out, and above-mentioned two kinds of heat just can accumulate on mould, cause die temperature to rise.When machined surface temperature exceedes the heat resisting temperature of lubricant film, just can there is the direct contact of metal, sintering fault the most easily occurs.Therefore cold forging requires also very high to lubricant.
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.Heat forging technology is the more complete processing of Recent study.The development of heat forging technology mainly develops high value-added product, and its forging quality produced 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 machine own wt; Save metallic substance; Reduce production cost, production efficiency is high.Meanwhile, it is also constantly to the infiltration of the field such as cutting, powder metallurgy, casting, forge hot, sheet forming technique or replace, and also can to combine formation recombining process with these technique.With heat forging technology, processing advantage carries out to aluminum and aluminum alloy mateial many, but due to the characteristic of metal fluid and bearing pressure comparatively large, the integrity of forging be ensured, extend the work-ing life of mould and equipment, suitable lubricant must be used.
