Abstract
The present invention belongs to alloying techn. Inorganic staple is added into water solution of adhesive to produce prefabricated reinforcer part, into which aluminium alloy is infiltrated to form cylindrical aluminium-base composite blank. Annular hoop is produced through extrusion and machining and finally it is firmly embeded onto wheel hub. As a good manufacture method, the present invention can produce light, large-brake force, safe and wear-resisting wheel hub.
Description
The present invention relates to a kind of hub design manufacture method of inserted aluminum matrix composite motorcycle hoop, it belongs to alloy or wheel technical field.
Before the present invention, the traditional handicraft of wheel hub is the steel ring spoke type, and hoop is cylinder iron made, and therefore, coefficient of friction is little, and brake force is low, gets rusty easily, and it is dangerous to drive a vehicle, and adds man-hour, because of graphite dust causes environmental pollution.
The manufacturing method of wheel hub that the objective of the invention is to overcome weak point of the prior art and a kind of inserted aluminum matrix composite motorcycle hoop is provided.
Task of the present invention is finished by following measures: a kind of manufacture method of hub of motorcycle, at first solve the material property of hoop, hoop adopts inorganic short fiber reinforcing agent adding to have in the aqueous solution of bonding agent, make the reinforcing agent prefabricated component, then aluminium alloy is infiltrated up in the prefabricated component, form cylindrical aluminum based composites blank, adopt extrusion process to make the hoop pipe, be machined into the aluminum matrix composite motorcycle hoop that meets dimensional requirement again, and then be embedded in hoop on the wheel hub securely, both reach the material property that strengthens hoop, reached easy processing method again.
Accompanying drawing 1 is the structural representation of wheel;
Accompanying drawing 2 is the axial section of hoop (1);
Accompanying drawing 3 is made composite hoop (1) pipe schematic diagram for backward extrusion technology.
The present invention describes in detail embodiment below with reference to accompanying drawing: a kind of bike wheel is by wheel hub 2, hoop 1, drum covers 3 to be formed, as shown in Figure 1, the manufacture method of hub of motorcycle, at first the inorganic short fiber of reinforcing agent being crushed to draw ratio is 5～100, join then that to have bonding agent content be to stir in 3～20% the solution container, in vacuum, forming under the pressure, make the cylindric prefabricated component of the volume content 5～25% of inorganic short fiber, this prefabricated component is handled through the segmentation oven dry again, 80 ℃～120 ℃ stages moisture content is dried, again 120 ℃～400 ℃ insulations, dry by the fire up to organic adhesive, prefabricated component after will drying again is sintering in 500 ℃～1000 ℃ stoves, makes prefabricated component have certain mechanical strength, is not easy distortion so that can bear under the TUBE BY LIQUID EXTRUSION condition.Secondly, the cylindric prefabricated component behind the sintering is put into die cavity, mold heated to 200 ℃～400 ℃ pours in the die cavity having 680 ℃～850 ℃ molten aluminium alloy, at 100～1000MPa/mm
2Pressure under, aluminium alloy is infiltrated up in the cylindric prefabricated component, under pressure, solidify, make inorganic short fibre content and be 5～25% cylindrical aluminum based composites blank 9.If reinforcing agent is an inorganic particle, then the reinforcing agent inorganic particle is preheating in the half curdled appearance molten aluminium alloy of sending into 650 ℃～720 ℃ after 600 ℃～1000 ℃ and stirs, being warmed up to 700 ℃～800 ℃ then, to be cast into inorganic particle content fast be 5～25% cylindrical aluminum based composites blank 9.The 3rd, adopt forward extrusion or backward extrusion technology to make composite hoop 1, be backward extrusion technology as shown in Figure 3,4 is patrix, and 5 is pressure head, and 6 is die, and 7 is heater, and 8 is bed die, and 9 is the composite blank.Cylindrical aluminum based composites blank 9 and mould all are preheating to 350 ℃～500 ℃, blank 9 is put in the mould exerts pressure, pressure is 100～500 tons, can make aluminum matrix composite hoop 1 pipe with certain size requirement, be cut into hoop 1 again, as shown in Figure 2.At last, the hoop 1 after the processing is positioned on the core rod of wheel hub 2 moulds, gets togather mould, the molten aluminium alloy with 680 ℃～850 ℃ is poured into fill type in the die cavity, at 100～1000MPa/mm
2Coagulation forming under the pressure has so just adopted die casting or TUBE BY LIQUID EXTRUSION to prepare the hub of motorcycle 2 of inserted aluminum matrix composite hoop 1.
The present invention has in light weight, and brake force is big, and security is good, the advantages such as durable wear, It is a kind of comparatively desirable hub of motorcycle manufacture method.
