Abstract
The invention provides a making method of a composite material wheel rim. The method comprises the following steps: 1, mandrel making: making a solid mandrel with a predetermined shape by using stearic acid; 2, composite material attachment: attaching the outer peripheral surface of the mandrel with a composite material; 3, molding: placing the composite material attached mandrel in a die, heating the die and the composite material attached mandrel at 120-140DEG C for 70min in order to make the composite material closely harden-molded to form a wheel rim; and 4, mandrel removal: heating the mandrel in order to make the mandrel molten and flow out of the wheel rim. The method realizes the recycle of the mandrel, saves the cost, and can avoid the influence of through holes caused by the permeation of the molten mandrel to the slit of the composite material on the yield.
Description
Technical field
The present invention relates to the manufacture method of composite material rim technical field, particularly a kind of composite material rim.
Background technology
The manufacture of existing composite material rim often with airbag as mandrel, composite wood attaches or is coated the outer surface of this airbag, after heating press molding, gas leakage in this airbag is taken out airbag or directly by airbag indwelling in wheel rim, but, airbag inside is gas after all, and airbag itself be necessary for flexible materials can inflate and lose heart, cause airbag shape fixing not, surface still has certain elasticity, therefore composite wood is difficult to tight attaching, also difficulty maintains solid shape, if it is more fixing to want airbag shape, airbag internal gas pressure must increase, but easily cause broken bag phenomenon, make wheel rim manufacture failure, and the airbag of indwelling in wheel frame increases cost and more not environmental protection beyond doubt.
For improving this disappearance, have with foaming material as mandrel person, described in TaiWan, China publication number 201043488 and 201219183 patents, foam as the mandrel of solid shape by foaming material, attach again composite wood in mandrel outer surface and then moulding, after moulding, available organic solvent dissolves mandrel and derives, though the mandrel of foaming material has more fixing shape compared with airbag, but its reaction of dissolving taking solvent is as irreversible, cannot reply former foaming material once dissolve, therefore be difficult to recycling, cost is still high and cause more serious environmental pollution, and foaming material is expansion molding, structure is bulk, structural strength is still not enough.
In addition, in TaiWan, China publication number 200906649 patents, more disclosed using low-melting-point metal as mandrel, after wheel rim moulding, to mandrel, heating makes it fusing and then can in wheel rim, flow out, though the metal of outflow is recycling, but weight metal is heavier, unfavorable manufacture, and cost is also high, the more important thing is, even low-melting-point metal, still need higher temperature to melt, high temperature destroys the wheel rim of firm forming most probably, and makes yield not good.
Summary of the invention
The object of this invention is to provide a kind of manufacture method of composite material rim, mandrel retracts can be recycled, and mandrel has preferably structural strength, the wheel rim yield raising of making.
For achieving the above object, the present invention takes following technical scheme:
The manufacture method that the invention provides a kind of composite material rim, comprises following steps:
Prepare mandrel: this mandrel is solid and has a predetermined shape, this mandrel is made with stearic acid;
Attach composite: attach a composite in the outer peripheral face of this mandrel;
Moulding: insert in a mould attaching the mandrel of this composite, with the temperature of 120-140 DEG C, this mould and the mandrel that attaches this composite are heated approximately 70 minutes, making the closely knit hardened forming of this composite is a wheel rim;
Remove mandrel: this mandrel heating is made it to melt and this mandrel is flowed out from this wheel rim.
The mandrel of described mould and described attaching composite is heated with the temperature of 130 DEG C.
In the step that removes mandrel, be that described mandrel is heated 2.5 hours with the temperature of 150 DEG C.
Preparing after the step of mandrel, is to be first coated with after an off-shape agent at the outer peripheral face of described mandrel, just described composite is attached to described mandrel.
Described composite is carbon cloth.
The invention has the beneficial effects as follows: by this, the mandrel that the manufacture method of composite material rim provided by the present invention is used is shaped easily, structural strength is good, surface is careful, hardness is high, fusing point is not too low, more can repeat to reclaim use, and be difficult for because hardness is low and the too low gap of infiltrating composite of fusing point causes hole generation that yield is reduced.

Detailed description of the invention
Below only with embodiment, the enforcement aspect that the present invention is possible is described, so not in order to limit the category of institute of the present invention wish protection, close first chat bright.
Please refer to Fig. 1 to Figure 10, the invention provides a kind of manufacture method of composite material rim, comprise following steps:
Prepare mandrel: this mandrel 1 is for solid and have a predetermined shape, and as shown in Figure 1, this mandrel 1 is made with stearic acid (stearic acid), wherein, can be first by stearic acid fusing and note in a mould, make it the demoulding after hardening by cooling and form this mandrel.
Attach composite: attach a composite 2 and form a formed body A not in the outer peripheral face of this mandrel 1, as shown in Figure 2, wherein, in main embodiment of the present invention, this composite 2 is carbon cloth, and carbon cloth is wound to the outer peripheral face of this mandrel 1; And in other possibilities of the present invention embodiment, can first after the outer peripheral face of this mandrel is coated with an off-shape agent, again this composite be pasted to the surface of this mandrel, so that the disengaging each other of follow-up mandrel and composite.
Moulding: as shown in Figure 3, insert in a mould 3 attaching the mandrel 1 of this composite 2, with the temperature of 120-140 DEG C, this mould 3 and the mandrel 1 that attaches this composite 2 are heated approximately 70 minutes, making the closely knit hardened forming of this composite 2 is a wheel rim.More particularly, this mould 3 comprises a pair of die body being mutually symmetrical 31,32, this not formed body be placed in this to the space between die body 31,32, as shown in Figure 4, then to this mould 3 and this not formed body heating pressurization, making the closely knit hardened forming of this composite 2' is a preform B, as shown in Figure 5; In preferred embodiment of the present invention, be to this mould and this not formed body (attaching the mandrel 1 of composite 2) heating with 130 DEG C.
The demoulding: as shown in Figure 6, this two die body 31,32 is departed from from this preform B.
Boring: as shown in Figure 7, the composite 2' part boring of this preform is formed to a perforation 21, as the spoke hole of wheel rim.
Remove mandrel: this preform heating is melted this mandrel and this mandrel 1' is flowed out from this wheel rim, in more detail, please refer to Fig. 8, be with 150 DEG C, this preform to be heated 2.5 hours, this mandrel be molten into aqueous, and can flow out from this perforation 21, remaining composite 2' becomes a formed body C, as shown in Figure 9, this formed body C can directly become a composite material rim or after other procedures, become a composite material rim again, as shown in figure 10.
By this, the manufacture method of composite material rim provided by the invention has the following advantages:
One, high, the more general wax of fusing point of mandrel hardness is high, is not easy to melt under room temperature, infiltrates the gap of carbon cloth therefore can avoid fusing, causes the wheel rim of moulding produce perforation and cannot use;
Two, the recyclable recycling of mandrel, and reclaim and make and be all easier to again;
Three, mandrel moulding is easy, and shape fixes, and surface is careful;
Four, the one that is aliphatic acid due to stearic acid, thus the mandrel forming be difficult for carbon cloth be stained with glutinous, therefore be difficult for residuing on wheel rim;
Five, cost is lower.
