Description
Technical field
The present invention relates to a kind of copper alloy and preparation method for being used to manufacture quick punching machine guide sleeve.
Background technology
Copper alloy has higher mechanical property and wear-resisting property, and very high thermal conductivity and electric conductivity, are in industrial production
One of widely applied structural material.Copper alloy is widely used in and defends because having good mechanical property and machinability
Raw sanitary ware, plumbing, instrument and meter, hydraulic valve etc..Although copper crystallization range is small, mold-filling capacity is strong, have certainly
Getter action of hair etc., but since copper easily forms thick column crystal in process of setting, cast sturcture's roughening, was casting
In journey easy hot tearing and using process exist leakage phenomena such as, influence its performance, especially under some high rigidity occasions by
Guide crystal thermal crack resistant and compactness for copper alloy, hardness to have high requirement in the impact of high frequency, how to improve
The fine and closely woven degree of copper alloy crystal, hardness, reduce the object that impurity in alloy is always those skilled in the art's research.
The content of the invention
The present invention provides Albatra metal column crystal refinement, impurity content is low, hardness is high not easy to crack is used to manufacture
The copper alloy and preparation method of quick punching machine guide sleeve.
It is a kind of to be used to manufacture the copper alloy of quick punching machine guide sleeve, including percentage by weight is：9.5-10%Sn, 0.2-
0.3%Ni, 0.2-0.3%P, surplus Cu.The present invention rationally adjusts the gold of copper using copper as elements such as base material addition tin, nickel, phosphorus
Belong to characteristic and reached novel alloy tensile strength >=370, extensibility >=10, the technical characteristic of hardness HB >=90, has well
Greasy property and ductility.
In the Cu 0.02-0.03% of Cu weight is accounted for containing boron, titanium, zirconium, wherein boron, titanium, zirconium.Above-mentioned element exists
Account in the range of the 0.02-0.03% of Cu weight and significantly refined the crystal grain of copper alloy so that the compactness of copper alloy greatly improves.
The boron, titanium, the weight ratio of zirconium are 2:1:1.
A kind of process for producing copper alloy for being used to manufacture quick punching machine guide sleeve：
(1) crucible is preheated to kermesinus (500 DEG C) in stove, adding prepared flux weight item ratio is：20%
Ten 20% calcirm-fluoride of ice crystal, ten 60% sodium fluoride.
(2) Cu is fitted into rapid melting in the crucible after preheating.
(3) weight alloy 9.5-10%Sn, 0.2-0.3%Ni, 0.2-0.3%P are added after copper is melted, stirring rod will
It is pressed into；At this moment because exothermic reaction makes to melt quickly, and alloy temperature is rapidly increased to more than 1200 DEG C.
(4) the 5-10% copper left in advance is added, to adjust temperature, the temperature for finally adjusting aluminium alloy is 1150-1175
℃.Then pass to chlorine 3-5min and carry out refinery by de-gassing, stirring slagging-off, tapping casting.
(5) centrifugal casting mould preheating temperature is 160-200 DEG C, and mold work temperature is 60-80 DEG C；Cooling velocity is

In Cu in the step 2,4 0.02-0.03% of Cu weight is accounted for containing boron, titanium, zirconium, wherein boron, titanium, zirconium.
Cu in the step 2,4 is the copper ball structure that two semicircles mutually fasten composition, and copper ball is built-in with the activity of coconut husk manufacture
Charcoal.This kind of copper ball structure brings the activated carbon that coconut husk manufactures inside copper liquid into, and with the thawing of copper ball, activated carbon is in solution
It is internal to occur reduction reaction with the oxide of copper, and due to the lighter weight of activated carbon, it can float during reacting, this
Kind, which floats, can not only occur more fully reduction reaction, but also improve the mobility of copper solution, final substantial amounts of activity
Charcoal forms one layer of anti oxidation layer with the impurity of floating on copper liquid surface, prevents copper liquid from oxidation reaction occurs, further improves copper
The purity of liquid.Nitrogen of the activated carbon of the coconut husk manufacture when infiltration 24 is small before inserting copper ball.Since activated carbon is good
Absorption property, the activated carbon Gas Phase Adsorption performance of particularly coconut husk manufacture is more preferable, its a large amount of nitrogen adsorbed is heated to vaporize and is formed
Substantial amounts of fine and closely woven bubble so that the element such as poisonous metal and hydrogen in copper liquid is sufficiently taken away by impurity very much to be floated.
Cu in the step 2,4 is helical tubular structure, the activated carbon of filling coconut husk manufacture in tube body.Spiral shape
The copper alloy of tubular structure is spiral shape namely by the alteration of form of the activated carbon of coconut husk manufacture, this spiral shape activated carbon with
The thawing of copper, reduction reaction occurs inside solution with the oxide of copper for activated carbon, and due to the lighter weight of activated carbon,
It can float during reacting, and more fully reduction reaction can not only occur for this floating, but also improve copper solution
Mobility, final substantial amounts of activated carbon forms one layer of anti oxidation layer on copper liquid surface with the impurity of floating, prevents copper liquid from sending out
Raw oxidation reaction, further improves the purity of copper liquid.The activated carbon of the coconut husk manufacture is when infiltration 24 is small before inserting copper ball
Nitrogen.Due to the good absorption property of activated carbon, the activated carbon Gas Phase Adsorption performance of particularly coconut husk manufacture is more preferable, it is adsorbed
The vaporization of being heated of a large amount of nitrogen form substantial amounts of fine and closely woven bubble so that the element such as poisonous metal and hydrogen in copper liquid fills very much
Being taken away by impurity for dividing floats.
The present invention has reached new by rationally adjusting the metallic character of copper using copper as elements such as base material addition tin, nickel, phosphorus
Strength of alloy >=370, extensibility >=10, the technical characteristic of hardness HB >=90, has good greasy property and ductility
Energy.
