Background technology
Carbon fiber reinforce plastic material (being called for short composite wood or multiple material) owing to light weight, intensity height, is widely used among the various products.At present, the wheel rim of wheel such as bicycle or wheelchair just adopts composite wood to make mostly.The making forming method of multiple material wheel rim and the forming method of other composite products are roughly the same, normally complex fabric cloth being wound into tubular is placed in outside the airbag, or with the complex fabric cloth airbag outside face that has been sticked, afterwards fiber cloth is positioned in the mould together with airbag, charge into high pressure gas then in airbag, heating gets final product curing molding.
And for wheel rim, because its outer ring surface need be connected with tire, therefore the outer ring surface of wheel rim 1 is provided with draw-in groove 11 in order to cooperating with the tire lip of tire, and the both sides, outer end of this draw-in groove 11 also are provided with inner convex platform 12 and engage (cooperating shown in Figure 1) with groove outside the tire tire lip.Therefore wheel rim also needs the extraction-type slide block is set on mould when moulding, can after moulding slide block be taken out in draw-in groove.TaiWan, China I236983 patent case, a kind of " manufacture method of bicycle rim " promptly disclosed, as shown in Figure 1, the extraction-type slide block that this manufacture method adopts is the mould heart 2 that silica gel is made, because silica gel has certain pliability, therefore wheel rim by making the silica gel distortion, can just take out the mould heart 2 after moulding in draw-in groove 11.
Existing wheel rim method for making, because wheel rim draw-in groove outer end edges and inner convex platform position belong to the fringe region of product, in the process of laying silvalin, always have phenomenon inhomogeneous or the silvalin location difficulty, when hot forming, it is good that the flowing power of the complex fabric cloth after the heating also can not show a candle to liquid plastic, therefore after moulding, surpass the phenomenon that mould matched moulds zone will form gum deposit or yarn clipping (being clipped between slide block and the mould) for the silvalin location, can form breach for thin position, therefore wheel rim is after moulding, the common unfairness of its draw-in groove outward flange and need secondary processing.But for the defective of yarn clipping, adopt secondary processing can also make product reach appearance requirement, and, then certainly will become waste product, must scrap for the defective that forms breach.In addition, even pass through secondary processing, what can solve also just satisfies appearance requirement, yet, this fringe region is because gum deposit makes the material non-uniform phenomenon that is produced after the moulding also will influence this regional intensity, and the draw-in groove zone of wheel rim is the critical positions that need cooperate with tire, and its requirement of strength and dimension precision requirement are all higher, and therefore uneven intensity will make wheel rim form defective products.Moreover, since wheel rim draw-in groove fringe region in the shop problem of non-uniform during yarn, cause the burr size that forms because of yarn clipping also very inhomogeneous, so just brought very big degree of difficulty, cost that will the increase secondary processing to secondary processing.
By above-mentioned analysis as can be known, method for making, the especially defective of the processing technology in draw-in groove outer end edges zone of existing wheel rim will easily make the wheel rim of making form defective products or waste product, and the following process difficulty, the cost height.
Summary of the invention
Technical matters to be solved by this invention is to provide a kind of method for making of composite material wheel rim, and it can make the wheel rim draw-in groove zone outer end edges intensity after the moulding even, and shape is complete, and following process is easy.
For solving the problems of the technologies described above, technical solution of the present invention is:
A kind of method for making of composite material wheel rim comprises the steps:
1) molding semi product wheel rim, the inner convex platform at the draw-in groove edge of this semi-finished wheel rim is reserved a stock left for machining outward;
2), the stock left for machining of semi-finished wheel rim is removed, and only had the finished product wheel rim of draw-in groove and two inner convex platforms by back processing.
Numerically-controlled machine tool or plain turning machine processing are adopted in the processing of described back.
After adopting such scheme,, can reach following effective effect at least by this stock left for machining because the present invention when the moulding wheel rim, has designed a stock left for machining in the inner convex platform outside of wheel rim draw-in groove:
1. by increasing this stock left for machining, the fringe region of semi-finished wheel rim is extended to the stock left for machining position, make gum deposit, yarn clipping and gap problem be formed on this stock left for machining place, therefore can guarantee the complete of draw-in groove shape, can avoid simultaneously defective, and cause bad or scrap because of processing technology.
2. by back processing, can guarantee the out of roundness of wheel rim.
3, since additive incrementation stock left for machining, this stock left for machining has certain size, and does not resemble by the formed burr of the wheel rim of orthodox method moulding lessly and inhomogeneous, so following process is more easy, back tooling cost is lower.
