Abstract

This invention provides a method for manufacturing abrasion-resistant bicycle rims and products made by same, wherein the method includes preparing and forming material to obtain a rim blanket. The rim is formed on its outer end face with an engagement slot having an irregular shape. The blanket is then subject to deburring, edge trimming and sand blasting prior to filling an abrasion-resistant and heat-resistant composite material into the engagement slot. The blanket is then subject to settling, drying, drilling and painting to obtain a final product for a bicycle rim. Wile the rim is joined and assembled to the bicycle so as to come into contact with or abrade against the brake pad, the abrasion-resistant and heat-resistant composite material filling can provide better abrasion-resistant and heat-resistant effect.

Description

200540030 V. Description of the invention (1) [Technical field to which the invention belongs]. ί ί: The main f system reveals a method for manufacturing bicycle rims and its system

Ii η 2: It is a method for manufacturing bicycle rims with better fortune and its clothing. [Previous technology] The second f * today's structural form is called the new moon *, and the people need to have a life ::: quality / :: improvement, and the requirements for things have been changed from "useful". Tired, only continuous construction or innovation can meet the needs of modern society. At present, conventional bicycles make self-made fibers from s ==, 0, as shown in the figure-which reveals a pair of side walls η, the two sides are two, and the rim 10 mainly has a tire and a tire (Figure (Not shown) knots toward the engine part 12 'when the rim 10 • when the privy is determined ~ σ, the card can be fixed by the card catching portion 12, and then come, the carbon fiber rim 10, i 1 advantages, but the relative anti-scratching agent ZU, although it has a lighter quality, so 'if the heart of the bicycle ::: is slightly worse than the squeeze-type rim, it will release the ancient due to friction Hold, friction of the brake surface 13 of the rim 10, but in order to improve this-missing ,: Second City: Sticker 2 that will cause the rim 10 to crack and damage the efficacy. Attached to the rim / = two J has a more wear-resistant structure, the sticker 2. That is to say, the brake pads and = = are used to reinforce the friction ability of the rim 10. The medium during U friction is bad, but the above-mentioned bicycle rim 10 is in order, and the sticker 20 on the rim 10 is: there is a lack of it, and its attachment method is combined, so it is producing 200540030 V. Description of the invention (2) High heat In this case, the adhesive system on the sticker 20 will be melted, causing the sticker 20 to lose its viscosity and fall off. The "brake pad of the bicycle is directly in contact with the rim and rubs" is the same as the above description. Direct damage to the rim 丨 〇 with the same heat 'Moreover' If the sticker 2 〇 directly wears out and causes unevenness in the end face, it means that the rim 丨 〇 must be replaced in a complete set to avoid the inadvertent braking This kind of sticker 2 〇 The thickness of the general design thickness can withstand a limited number of friction, which means that such rims must be replaced from time to time, which indirectly increases the user's disassembly time, and also wastes the replacement wheel. The cost of rim 10 is required, so the conventional bicycle rim should be improved. [In the invention, the hair still has the method and degree of resistance to the hair, and for the sake of segmentation, the rim is filled with a hole through the thick limb, and the filling is filled with the content.] The reduction of products makes it possible to achieve the main purpose of providing the chamfering clock which is prepared by preparing materials at the outer end, such as deburring and grinding, which is the user's more aforesaid abrasion resistance, molding surface system, and car side heat recovery. The shortcomings of conventional heat-resisting conventional tactics are to improve the ability to effectively change rims. The self-made process is provided with a sandblasted composite material, which can be used to make composite material bicycle rims for practical use. Therefore, it is redesigned. Provides the number of grinding cycles for lifting a bicycle rim with a wear-resistant bicycle rim. Yes, this wheel rim system can be used to produce a rough rough rim with irregular processes. The technology and methods used to make the rim are shown in the following. Then, by standing, drying, and producing a finished product of a bicycle rim, and 'so the rim is combined and assembled to itself

That is, it has better abrasion resistance, car resistance, and thermal efficiency when it comes into contact with the car piece. [Embodiment] The technology, means and money used in the present invention are compared with the examples of the shellfish and the diagrams in detail as follows: In the special: = diagram to the fourth diagram, the ones shown in the diagram are for illustration only. It is not restricted by this type of structure in profit-seeking Jiaming. See the second picture '* The process of manufacturing abrasion-resistant bicycle rims includes: Preparation A, this stage is to prepare carbon fiber material; Forming B, this stage is to make and shape the rim 30 as shown in the third picture , It has a pair of side walls 31, and the outer side 32 of the two side walls 31 is provided with an irregularly shaped combining groove 33. In this embodiment, the cooperative groove 33 is wavy; ^ Deburr C, remove the burr left by the molding rim 30; Lathe β, this stage is to trim the rim 3 by turning; sandblasting Ε; wear-resistant hot material coating F, this stage will be a wear-resistant The heat-resistant composite material 40 (refer to the fourth figure) is coated in the above-mentioned bonding groove 33 and fills the bonding groove 33 '. The composite material 40 can be a combination of epoxy resin and metal powder, or It is a combination of resin and metal powder, and both of the above two combinations can make the composite material 40 have excellent wear resistance and heat resistance; stand still G, this stage is the rim 3 which has filled the composite material 40 above. 〇 set

Put it in an appropriate position to wait for the natural cooling of the composite material 40; Hong GanΗ 'At this stage, the above-mentioned rim 30 is dried and treated 7' to remove excess water; to surface treatment I 'this In the stage, the above-mentioned rim 30 can be subjected to the final surface treatment through soil filling, drilling, and coating, which is to complete σ, σ. Referring again to the fourth figure, this is a diagram of a wear-resistant bicycle rim according to the present invention. Referring to the figure, the bottom end surface of the coupling groove 33 of the rim 30 is set as a leaf, so the contact area between the composite material 40 and the rim 30 is relatively large. The coupling relationship between them is more stable, and it is easy to pull off. Because the composite material 40 fills the coupling groove 33, and the outer surface 32 of the composite material 40 surface rim 30 is aligned, the rim 30 is installed. In bicycles (pictured), the composite material 40 can be used to resist the friction of the brake pads. As mentioned earlier, the composite material 40 can be a combination of epoxy resin and metal powder ^, and can be a phenolic resin and metal. The combination of powder, so its abrasion resistance has abrasion resistance; and one must pay attention here, the composite material 40 can also penetrate into the pigment to produce an obvious contrast with the color of the rim 30, so 'A field complex σ material 40 can wear a period of time, you can clearly observe the degree of change' to achieve the effect of enhanced warning. The invention has been described with reference to the detailed drawings of the preferred embodiment.技 This artist is a model that can be derived from the best embodiment of Xu Xiang change without 2 _. Therefore, the preferred embodiment limits the pain of the present invention. The scope of the invention is defined in the scope of patent application. can
