Embodiment 1

[0033] Embodiment 1, please refer to figure 1 , figure 2 , image 3 , a method for producing a carbon fiber bicycle rim with an inner tube, comprising:

[0034] Cavity mold core production: cavity mold core production: the cavity mold core is used to form the cavity 11 of the fixed spoke of the rim, and the inflated plastic air bag 111 that is consistent with the shape of the cavity is covered with a carbon fiber layer 13. An aluminum strip 2 for fixing spokes is provided on the inner wall of the carbon fiber layer near the center of the rim;

[0035] Inner tube mold core production: The inner tube mold core is used to form the cavity 12 of the inner tube for forming the wheel rim. Firstly, the ABS plastic core 121, which is slightly smaller than the inner tube cavity and has the same shape as the inner tube cavity, is resistant to high temperature and high pressure and does not deform. A protective film made of OPP material containing silicone oil, and then coated with a ...

Embodiment 2

[0040] Embodiment two, differ from embodiment one in that:

[0041] Cavity mold core production: The cavity mold core is used to form the cavity for fixing the spokes of the wheel rim. First, the Baolilong mandrel, which is slightly smaller than the cavity 11 and consistent with the shape of the cavity, is covered with a layer of plastic air bag 110. The bag is coated with a carbon fiber layer 111, and the inner wall of the carbon fiber layer near the center of the rim is provided with an aluminum strip 2 for fixing spokes;

[0042] Inner tube mold core production: The inner tube mold core is used to form the cavity 12 of the inner tube for forming the rim, and first wrap a plastic core 120 that is slightly smaller than the inner tube cavity, consistent with the shape of the inner tube cavity, resistant to high temperature and high pressure without deformation The protective film made of OPP material containing silicone oil is then covered with the carbon fiber layer 121; the ...

Abstract

The invention discloses a production method of a carbon fiber bicycle rim with a tire tube, which comprises the manufacturing of a cavity mold core, the manufacturing of a tire tube mold core, the assembly of semi-finished products, the forming of products, the takeout of the cavity mold core and the takeout of the tire tube mold core. The tire tube mold core made of plastic materials is light in weight, makes the production operation of workers convenient, and shortens the wrapping time of a carbon fiber layer, so that the production efficiency is improved; a layer of isolating film is arranged between the tire tube mold core and the carbon fiber layer and the isolating film contains silicone oil, so that the carbon fiber layer is not adhered to the tire tube mold core and is separated from the tire tube mold core easily, the tire tube mold core can be taken out of a formed rim tire tube cavity easily, the production efficiency of workers is improved further, and the labor strength and rejection ratio are reduced; because an integral made-up article is light in weight, when wrapped by the workers, the carbon fiber layer is more uniform and smooth; and due to the adoption of the manufactured tire tube mold core, the carbon fiber layer is high temperature resistant and high pressure resistant and has no deformation during in solidification forming time, and products formed by the carbon fiber layer can be easily controlled in size, have no deformation and reduce the strength.

Description

technical field [0001] The invention relates to a production method of a carbon fiber bicycle rim, in particular to a production method of a carbon fiber bicycle rim with an inner tube. Background technique [0002] People's living standards have improved, and the pace of life has accelerated. More people use their spare time for outdoor sports. While exercising, they can also feel the breath of nature. Therefore, bicycles that have been neglected have attracted much attention. Because it can not only exercise, but also can be used as a means of transportation. [0003] Today's bicycles are no longer the bulky and bulky bodies of the past. Manufacturers use carbon fiber to produce carbon fiber bicycles that are light in weight and flexible in structure. Since the bicycle rim needs to be equipped with an inner tube while fixing the spokes, the bicycle rim must be provided with two cavities. The current technology used to form the two cavities of the bicycle carbon fiber rim ...
