Description

A kind of sink
Technical field
The invention belongs to field of mechanical technique, is related to a kind of sink.
Background technology
Sink is kitchen heart, be an indispensable part for cabinet installation, and sink makes in all kinds of articles for use in kitchen With rate highest, preparing before meals with cleaning work after meal, the most of the time directly uses related to sink.In modern kitchen Sink often uses what stainless steel was produced for raw material, and stainless steel quality is light, performance is stable and durable, It can be made into the sink of different shaping style by Precision Machining, can be matched with all kinds of kitchen countertops.Part sink is using During need preferable heat dissipation performance, but existing sink is most of to be manufactured using stainless steel material, stainless steel Heat dissipation performance be not fine, and if the preferable copper alloy of heat dissipation metal, the performance of existing copper alloy is not high, is ensureing to dissipate While hot property, it is impossible to ensure the mechanical strength of alloy, it is therefore necessary to existing technology is improved, there is provided Yi Zhongji Energy quick heat radiating, there is the sink with higher mechanical strength.
The content of the invention
The purpose of the present invention is in view of the above-mentioned problems existing in the prior art, it is proposed that a kind of intensity is high, the water of good heat dissipation Groove.
The purpose of the present invention can be realized by following technical proposal：A kind of sink, the sink are made of copper alloy, institute The component for stating copper alloy is by mass percentage：Sn1~2%, Ni1~2%, Si0.1~0.2%, Zn0.2~0.5%, Mn0.02~0.04%, Bi0.1~0.2%, Cr0.15~0.3%, Sc0.01~0.04%, Al2O30.5~3%, graphite 2~ 3%, surplus Cu.
Solid solubility of the Zn in Cu is that 39.9%, Sn solid solubility in Cu is 15.8%, and Ni can with Cu infinitely dissolves, They form continuous solid solution with copper, have broad monophase field, they can significantly improve mechanical performance, the corrosion resistance of copper Can, Si can be with limited solid solution in copper, the solid solubility change fierce with temperature change, after temperature is crystallized from alloy to be completed When beginning to decline, their solid solubility in copper also begin to reduce, and are separated out with metallic compound or elemental form from solid phase, when These element solid solutions can significantly improve its intensity in copper, have solution strengthening effect, when they are separated out from solid phase When, and dispersion-strengthened effect is generated, conductive and heat conductivility is recovered, and the intensity of copper alloy can both have been improved by adding Si The heat conductivility of copper alloy can be improved again, and a small amount of Mn can be used as deoxidier, and manganese can improve the intensity of copper, and low copper-manganese closes Gold utensil has high-strength and corrosion resisting property, and copper-manganese resistance temperature system is seldom, due to there is allotropic transformation, makes phase under cupromanganese solid-state Become sufficiently complex, there is the process such as spinodal decomposition, metacrystal transformation under solid phase, make Cu alloys that there is impact-resistant performance, addition The diffusion process that a small amount of Sc elements make copper ion pass through oxide layer receives very big suppression, so as to substantially reduce oxidation speed Degree.The Cu alloys of rare earth Sc are added, the compactness and adhesion that can make oxide-film are all improved, this is because rare earth Sc is added After refined crystal grain, and the refinement of Cu-Cr alloy grains can increase the self-healing capability of protective oxide film.In these structures Difference effectively increases the resistance that parent metal ion passes through oxide-film, significantly reduces the growth rate of oxide-film；At the same time The addition of rare earth Sc, Cr particles easily in grain boundaries segregation, quickly spread transmission to reaction front when there is enough Cr along crystal boundary When, beneficial to generation Cr2O3Protective film.The present invention is reasonably to match the element of copper alloy, since the element of addition can produce phase Anti- reinforcing effect, it then becomes necessary to strictly control each element proportioning, could while copper alloy heat conductivility is improved, Improve the intensity of copper alloy.
A kind of preparation method of above-mentioned sink：Include step：
(1) raw material is configured, will slightly be refined, refined after the melting sources in addition to graphite powder, and is dusted work by nitrogen Copper powder is made in skill；
(2) screening copper powder, adds graphite powder, first grinding after being mixed with copper powder, and then HIP sinters to obtain alloy pig；
(3) at 850~950 DEG C by alloy pig hot forging into sink blank；
(4) sink blank is subjected to grade and stage timeliness, it is finally machined to obtain sink finished product.
Can be made the less alloy powder of granularity using the nitrogen technology of dusting, after alloy solution nitrogen powder with graphite Powder mixes, both can be sufficiently mixed, and is conducive to the progress of later stage HIP sintering, is not in the situation of element segregation.And use HIP sintering can ensure that direction is pressurized balance, obtained sintered products crystal grain than more uniform, while be conducive to alloying element it Between dissolve each other, relatively low temperature can be used under higher HIP sintering pressures, the phenomenon of abnormal grain growth will not be produced.Afterwards Phase can break crystal boundary again by hot forging, coordinate grade and stage timeliness crystal grain can more uniformly tiny, the production finally obtained Product intensity is high, due to alloy inside the defects of the also less progress for being conducive to heat dissipation, it may have higher heat dissipation performance.
Further, nitrogen powder injection process is in step (1)：0.5~0.8Mpa of nitrogen pressure, nozzle diameter are 3~5 millis Rice, 45~60 ° of inlet air angle.
During nitrogen powder, the pressure of nitrogen directly determines the effect of powder processed, if pressure is excessive, can cause Nitrogen wraps up in the grain, and the pressure of nitrogen is too small, and obtained alloyed powder particle diameter can be bigger, is unfavorable for the mixing in later stage, This preparation method uses the bore of suitable pressure cooperation nozzle, and obtained alloyed powder particle diameter is reasonably distributed, and is conducive to improve most The performance of finished product.
Further, the size grading of copper powder is in step (2)：Less than 75 μm granule contents, 75~90 micron particles contain Amount, more than 90 μm granule content ratios are 5~10:70~80：15~20.
Further, the graphite powder particle diameter in step (2) is 40~60 μm.
Since the content of copper powder is higher, the mixing of copper powder and graphite powder is substantially that graphite powder can be mixed sufficiently uniformly Close in copper powder, essence coordinates suitable graphite powder particle diameter by method using rational size grading, it is ensured that graphite powder is equal It is even to be sufficiently dispersed in copper powder, greatly improve the heat dissipation performance of final products.
Further, the HIP sintering conditions are：900~950 DEG C, 250~300Mpa of pressure of temperature, the time 2.5~ 3h。
Using suitable HIP sintering pressures, it is ensured that mixed-powder can sinter completely at a relatively low sintering temperature, At the same time can ensure crystal grain will not abnormal growth, ensure that sintering after the completion of alloy pig performance.
Further, in the step (3) in hot forging, hot forging deflection is 70~80%.
During hot forging, if deflection is excessive, the defects of larger can be also produced while original crystal grain is destroyed, And deflection is too small, it is impossible to destroy original crystal grain, and then the fixation rates in later stage would not tell on.
Further, grade and stage timeliness is in step (4)：
At a temperature of (1) 480~500 DEG C, 1.5~2h, brine-cooled are kept the temperature；
At a temperature of (2) 250~300 DEG C, 2~3h, water cooling are kept the temperature；
At a temperature of (3) 180~210 DEG C, 3~5h, natural cooling are kept the temperature.
Matched using grade and stage timeliness primarily directed to the different element of the present invention, alloying element is fully dissolved Into Cu, the invigoration effect of alloying element is played, and while hardness is improved, reduces the stress in alloy, reduces and uses During deformation and damage.
Compared with prior art, beneficial effects of the present invention are：
(1) matched using suitable element, give full play to the invigoration effect of each element, ensure the maximum of copper alloy performance Change；
(2) using the preparation method of optimization, the performance of copper alloy is further improved in preparation process, and then is improved final The heat dissipation of sink and mechanical property.
