Two of object of the present invention, is to be to provide a kind of producing process for the manufacture of excentric sleeve described in claim 1, it is characterized in that: comprise the following steps:
The first step, by various materials: copper, manganese, iron, magnesium, nickel, chromium, molybdenum are proportionally put into smelting furnace, dissolve;
Second step, pours dissolved material in mould into, and at this moment, the proportion of installation is directly added nano-graphite, molybdenumdisulphide, tetrafluoroethylene;
The 3rd step, directly carries out cooling down;
The 4th step is extracted out from mould;
The 5th step is carried out turning processing in lathe.
The present invention compared with prior art, has following beneficial effect:
The present invention is by adding copper, manganese, iron, magnesium, nickel, chromium, molybdenum, improves whole self intensity and physical strength, also reduces oxidisability, increases the service life and the maintenance of use properties; In addition, in order to improve self-lubricity, add nano-graphite, molybdenumdisulphide, tetrafluoroethylene, the oilness of whole capacity eccentric bearing is improved.
It is base material that the present invention adopts multiple alloy, selects optimal alloy composition and the scope meet design requirement with orthogonal experiment method, by copper content at 60-75%; Manganese content is at 2.5-8%; Iron level is at 2.5-5%; Mg content is at 3-5%; Nickel content is at 1-2%; Chromium content is at 5-12%; Molybdenum content is at 0.3-1%; Like this when melting, after copper alloy melts, at high temperature easily by the oxygen in furnace gas, be oxidized, owing to having added the larger element of avidity of other and oxygen, play deoxidation effect, as manganese, magnesium etc., form MnS with sulphur simultaneously, thereby play the sulphur effect that disappears, eliminate the deleterious effect of sulphur, be also beneficial to the intensity that improves copper alloy.
Wherein, manganese is white metal, and matter is hard and crisp.In metallurgical industry, be used for alloying, in alloy production with manganeseirom as desulfuration agent and Oxygen Scavenger, improve the quality of whole alloy, improve hardness and the toughness of whole alloy.Magnesium has more intense reductibility, magnesium and fluorochemical, hydrofluoric acid and chromic acid are not had an effect, not corroded by caustic alkali, mainly for the manufacture of structural performances such as light metal alloy, spheroidal graphite cast iron, scientific instrument and Grignard reagents, be similar to aluminium, the various uses with light metal, can be used as the alloy material of aircraft, guided missile.But magnesium is flammable at gasoline burning-point, this has limited its application.In the present invention, with magnesium, place other metallics oxidations, play reductive action, extend the work-ing life of alloy of the present invention.
Nickel is similar to silvery white, hard and have ductility and have ferromagnetic metallic element, and it can high polish and anticorrosive, has good ductility, has medium hardness, and nickel is silvery white metal, has magnetic and good plasticity-; The erosion resistance having had, is mainly used in alloy (as nickel steel and nickeline) and is used as catalyzer (as Raney Ni, being espespecially used as the catalyzer of hydrogenation).Anticorrosive for playing in the present invention, improve hardness, in making processes, play certain extensibility.
Molybdenum is mainly used in Iron And Steel Industry, and major part is wherein to be directly used in steel-making or cast iron after industrial molybdenum oxide briquetting, to add molybdenum in stainless steel, can improve the erosion resistance of steel.In cast iron, add molybdenum, can improve intensity and the wear resisting property of iron.So invention increases erosion resistance and intensity and wear resistance by adding molybdenum.
Chromium can be used for stainless steel processed, and chromium is plated in can be antirust on metal, firm attractive in appearance, so invention is by the interpolation of chromium, improves alloy, increases antirust ability and anti-corrosion capability.
In the present invention, added nano-graphite, not only had superpower mechanical property, tensile strength is 100 times of steel, and proportion is only 1/6 of steel, and thermal conductivity and diamond are similar, and specific conductivity is higher than copper, has excellent self-lubricating property simultaneously.
As from the foregoing, the present invention improves intensity, physical strength and the wear resisting property of self, has lubricant effect simultaneously.
In order further to explain technical scheme of the present invention, below by specific embodiment, the present invention will be described in detail.
