Description
Technical field
The present invention relates to a kind of pipe fittings, belong to metal material field.
Background technique
Pipe fitting is the fastening means between pipeline and pipeline, is the tie point that can be dismounted between element and pipeline.?
Indispensable key player is acted as in pipe fitting, it is one of two main composition parts of hydraulic pipeline.Pipe fitting is used for
The connection of instrument isoline, type of attachment have socket weld or threaded connection.It is mainly used for small-bore low-pressure line, it is frequent for needing
The position of assembly and disassembly or as using the final adjustment of threaded fitting pipeline to be used.Pipe fitting is frequently with forging cast iron materials manufacture.
Cast iron although intensity with higher is forged, is suitble to do structural material, but is easy to be corroded, and electroplating surface is then
It will cause the pollution of environment.So being made using aluminium alloy as material more properly.
Aluminium alloy refers to based on aluminium, and a certain amount of addition element is added and controls impurity content and the conjunction that forms
Golden system.Aluminium alloy has both high-intensitive, light-weight, good ductility, is suitable for structural material.In addition to aluminium alloy addition element
It will affect outside performance, the processing technology of aluminium alloy equally will cause influence, and traditional alloy is used and added using pressure processing, machine
Work Cheng Chengpin.It is not only weak in precision, but also intensity is inadequate.
It is low for traditional aluminum alloy hardness, it is not wear-resisting the disadvantages of, publication number 106048379A disclose one kind by aluminium
Toughness, elongation percentage that the member such as rare earth, strontium usually improves product are added in alloy.However, only promoting the toughness of aluminium alloy, extending
The performances such as rate can not enable aluminum alloy to reply complex environment.
Summary of the invention
In view of the above problems, the present invention provides high-intensitive, high hardness and corrosion resistance pipe fitting.
To achieve the goals above, the invention adopts the following technical scheme:
A kind of pipe fitting, the pipe fitting are made of aluminium alloy, the aluminium alloy by following mass percent raw material
It is made: Mg:0.05-0.1%, Mn:0.09-0.15%, Ni:0.12-0.18%, composite carbon: 0.07-0.17%, Zn:0.02-
0.04%, surplus is Al and impurity.
Preferably, the composite carbon is compounded by two or more carbon nanomaterial.
Further preferably, the carbon nanomaterial includes C60、C70, carbon microballon, one of single-walled carbon nanotube or more
Kind.
In conventional alloy raw material, often it is added using C as direct addition element.And the present invention is special using composite carbon
Be added, and use carbon nanomaterial for originally carry out compounding formed composite carbon, and form composite carbon carbon nanomaterial it
Between there is interaction, and can be applied in other alloying elements, the synergistic effect of composite carbon can effectively realize alloy stress
Transfer facilitates the tensile strength for promoting alloy.
The present invention additionally provides another technical solution while reasonable selection material mixture ratio:
A kind of preparation method of pipe fitting, includes the following steps:
(1) alloy smelting: being weighed by above-mentioned aluminium alloy stock, by all material mixed melting in addition to composite carbon
Aluminium alloy is formed, carbon nanomaterial is added in chloroform, is placed in hot bath, carries out the processing of nano-probe Ultrasonic Pulverization, then
It pours into room temperature solvent flashing in open vessel and obtains compound carbon powder；
(2) it refines: compound carbon powder is uniformly layed in pipe fitting mold, aluminium alloy is entered into mould through curved channel casting
In tool, it is cooled into pipe fitting semi-finished product；
(3) it forms: by the machined formation pipe joint finished product of pipe fitting semi-finished product.
The present invention utilize chemical synthesis, and cooperate physics probe oscillation by mutual exclusive carbon nanomaterial not of the same race into
Row is mixed to form composite carbon, and method is simple, is suitable for industrial production.Meanwhile the present invention pours aluminium alloy through curvilinear conduit
Note is the moment that aluminium alloy is transferred in curved channel in order to using buffer function of the turning point to aluminium alloy of curvilinear conduit,
An impulse force can be generated to crystal grain, cause die break, i.e. refinement crystal grain, promote the comprehensive performance of alloy.
Preferably, step (2) curved channel includes one or both of " S " type channel, " Z " type channel.By
In the impulse force for needing curved channel turning point, so the present invention selects the channel for having 2 inflection points.And inflection point is excessive, it can serious shadow
The mobility for ringing aluminium alloy, causes aluminium alloy partially cured and loses.
Preferably, step (2) described curved channel is horizontal by 30-50 ° of angle.Curved channel is not with horizontally or vertically
It is placed, being will not be too fast or too slow in order to preferably control the flow velocity of aluminium alloy, excessive velocities or will affect conjunction slowly excessively
On golden liquid cured opportunity, low-alloyed comprehensive performance drops.
Preferably, going back complementary field outside step (2) described curved channel.
Further preferably, the magnetic field can be rotated around curved channel, revolving speed 3-5r/s.
Mutually obvious refinement and nodularization, structural homogenity dramatically increase proeutectic in aluminium alloy under magnetic fields, make alloy
Liquid is produced from mixing effect, exacerbates falling off, dissociate and being proliferated for crystal grain, increases free number of die amount, enhance gold
Belong to the convection current inside liquid, weakens the constitutional supercooling in freezing interface forward position, to inhibit preferentially growing up for proeutectic phase.
Compared with prior art, the present invention has the advantage that
(1) synergistic effect of composite carbon of the present invention can effectively realize alloy stress transfer, facilitate the drawing for promoting alloy
Stretch intensity.
(2) aluminium alloy is poured by the present invention through curvilinear conduit, is delayed using the turning point of curvilinear conduit to aluminium alloy
Punching effect, the moment that aluminium alloy is transferred in curved channel can generate an impulse force to crystal grain, cause die break, that is, refine
Crystal grain promotes the comprehensive performance of alloy.
(3) applying rotating magnetic field in subtractive process of the present invention, so that proeutectic mutually obvious refinement and nodularization, group in aluminium alloy
It knits uniformity to dramatically increase, so that aluminium alloy is produced from mixing effect, exacerbate falling off, dissociate and being proliferated for crystal grain, increase
Free number of die amount enhances the convection current inside molten metal, weakens the constitutional supercooling in freezing interface forward position, to inhibit first altogether
Crystal phase is preferentially grown up.
