The lubricant composition can be directly used in a lubricating process of Al-Mg alloy precision die forging, is excellent in the performances of lubrication, cooling and thermal oxidization stability, is strong in dispersing, cleaning, infiltrating and bearing capabilities, enables a forged surface to be high in glossiness, achieves a high specification precision and enables size of parts to be stable, is suitable for various oil supplement methods, is long in anti-oxidizing and corrosion-resistant period and is convenient to use.
Description
Technical field
The invention belongs to the forging process field of lubricant in intermetallic composite coating, particularly aluminum magnesium alloy precision die forging lubricant compositions.
Background technology
Hydronalium has specific tenacity and specific rigidity is high, good heat conduction and electroconductibility, reflective is strong, plasticity good, good moldability, without advantages such as low temperature brittleness, damping shock absorption, electromagnetic wave shielding and accessory size are stable, be a kind of non-ferrous metal alloy material with excellent comprehensive performance, be widely used in the fields such as modern automobile industry, space industry, telecommunications industry, computer industry, household electrical appliances.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 aluminum magnesium alloy, and performance requriements is also more and more higher.
Precision die forging be the one that progressively grows up on common die forging basis less, without cutting smithing novel process.Stamp work can reach without surplus or little surplus and high-precisionly can be described as precision die forgings.Usually, its tolerance is about about 30% ~ 40% of common stamp work; And its surfaceness: steel part is less than Ra=5 μm, and non-ferrous metal pieces is Ra=0.63 ~ 2.5 μm.Have the advantages that to save a large amount of metallic substance, compared with open die forgings, material use efficiency improves more than 80%, and machining amount reduces more than 80%; Compared with common stamp work, material use efficiency improves more than 60%; A large amount of mechanical workout man-hour can be saved.Precision die forgings does not generally need mechanical workout or only needs a small amount of mechanical workout just can assemble use, and production efficiency is high.Particularly for some shape and be difficult to the part of machining process or batch production (such as; Gear, blade, high rib sheet part etc.), adopt precision die forging more to show superiority, not only production efficiency is high, and to a certain extent, its precision also can be equal to mechanical workout; Metal streamline can not be cut off along External Shape reasonable layout, is conducive to the fatigue property and the anti-stress corrosion performance that improve part.
Precision die forging is a kind of important method promoting that machine building industry productivity improves, and is also an important directions of forging technology development.It should be noted that: it is not be all economical under any condition.Because precision die forging requires the technical requirementss such as high-quality blank, accurate mould, the processing oxygen condition of low or non oxidizing, good lubrication and comparatively complicated inter process cleaning, so only under certain batch, the total cost of finished product could be reduced significantly.
