Abstract
The invention discloses a nut machining process. The process comprises the following steps: (1) alloy preparation: melting alloy at the temperature of 1200-1300 DEG C; (2) moulding by casting: cooling the melted alloy to 700-800 DEG C, guiding the melted alloy into a die to cast in a nitrogen environment, and then, carrying out a step quenching process to obtain a nut; (3) surface treatment: removing burrs and sharp points on the obtained nut, and sealing holes in silicon oil to obtain a finished product of the nut. The nut machining process disclosed by the invention is simple in process; melted alloy is low in impurity content after being refined, so that the unqualified product rate can be reduced during casting; the hardness of the nut is increased through quenching treatment; the surface smoothness of the nut is high through surface treatment.

Nut is exactly nut, the part that is used for playing the role of fastening together with bolt or screw rod are screwed in, and a kind of element that all manufacturings machinery must use, according to the difference of material, is divided into several large types such as carbon steel, stainless steel, non-ferrous metal (as copper).
The metallic substance that nut of the prior art uses mostly is the copper alloy that copper content is very high, and material hardness is lower, cannot meet the industry of high speed development, the demand of construction industry.
Summary of the invention
The present invention seeks to, be used for making up the deficiencies in the prior art, and a kind of complete processing of nut of high rigidity is provided.
To achieve these goals, technical scheme of the present invention is as follows:
A complete processing for nut, comprises following step:
(1) alloy is prepared: the weight percentages of components of described alloy is as follows: carbon 2-3%, and copper 10-15%, manganese 0.8-1.2%, silicon 1.3-1.8%, magnesium 0.2-0.4%, phosphorus is less than 0.08%, and sulphur is less than 0.08%, and surplus is iron; Be melting under 1200-1300 DEG C of condition in temperature;
(2) casting: the alloy after melting is cooled to 700-800 DEG C, in nitrogen environment, imports in mould and pours into a mould, and carries out stepped quenching process after cast, obtains nut after quenching;
(3) surface treatment: by the nut fin cutting and the wedge angle that obtain, then carry out sealing of hole processing obtain final finished nut in silicone oil.
The complete processing of described a kind of nut, described quenching technology is: the product after cast is incubated to 10-15min after being heated to 760-800 DEG C, in the oil that the temperature of quenching is afterwards 200-250 DEG C and be incubated 10-13min, then takes out at room temperature air cooling of product.
The complete processing of described a kind of nut, described alloy obtains by following steps: smelting furnace is preheated to 200-300 DEG C, adds raw material, be warming up to 780-820 DEG C, pass into nitrogen, add refining agent simultaneously, refining 10-15min obtains alloy molten solution.
The complete processing of described a kind of nut, described refining agent is Graphite Powder 99, consumption is the 0.3-0.5% of alloy molten solution weight.
The nut obtaining according to the complete processing of described a kind of nut.
Beneficial effect of the present invention is as follows:
Nut machining process of the present invention is simple, and alloy molten solution is by refining, and impurity is few, when cast, can reduce disqualification rate, by quench treatment, has improved the hardness of nut, and by surface treatment, the nut surface obtaining is highly polished.
