Problems solved by technology

[0009] However, the lateral rigidity (torsion rigidity) of the bicycle components made by the above-mentioned forming method is relatively insufficient. Therefore, the bicycle head tube made by the above-mentioned forming method limits the controllability of the bicycle frame, and The bicycle bottom bracket tube made by the above molding method limits the explosive force of the bicycle frame, so there is still room for improvement

Embodiment Construction

[0022] Below in conjunction with accompanying drawing and embodiment the present invention is described in detail:

[0023] Such as figure 2 , 3 , Shown in 4, the preferred embodiment of the forming method of the reinforced carbon fiber bicycle assembly of the present invention is applicable to manufacture a bicycle assembly 1, and comprises the following steps:

[0024] (1) Fabrication of a hollow foamed mandrel: a hollow and thin-walled mandrel 2 is made of a foamed material, and the mandrel 2 has a plurality of molding grooves 21 formed on the surface. The foaming material can be polystyrene foaming material, polyurethane foaming material, and epoxy foaming material, all of which can achieve the same effect. In addition, the thickness of the mandrel 2 is between 1mm and 10mm;

[0025] (2) Winding carbon fiber around the mandrel: a release layer is arranged on the surface of the mandrel 2, and then carbon fiber material is wound on the surface of the release layer. Afte...

Abstract

The invention discloses a method for molding a reinforced carbon fiber bicycle component. The method is suitable for manufacturing the bicycle component and comprises the following steps: manufacturing a hollow thin-wall mandrel by using a foam material, wherein the mandrel is provided with at least one molding groove formed on a surface; arranging a release layer on the surface of the mandrel and winding a carbon fiber material on the surface of the release layer; arranging an air bag in the mandrel to expand and position the mandrel; aerating the air bag and heating and pressurizing a carbon fiber material and the mandrel to harden and mold the carbon fiber material; and taking the air bag and the mandrel out, so the hardened and molded carbon fiber material becomes the bicycle component. The bicycle component is hollow and provided with at least one reinforcing rib which is formed on the inner peripheral surface of the bicycle component and corresponds to the molding groove.

Description

technical field [0001] The invention relates to a forming method of a bicycle component, in particular to a forming method of a reinforced carbon fiber bicycle component. Background technique [0002] Such as figure 1 As shown, the conventional forming method of a bicycle component is suitable for manufacturing a hollow bicycle component, and includes the following steps: [0003] (1) winding carbon fiber material on the surface of a mandrel; [0004] (2) Take out the mandrel; [0005] (3) Putting an air bag into the carbon fiber material; [0006] (4) heating the carbon fiber material and inflating the air bag to harden the carbon fiber material; [0007] (5) remove the air bag; and [0008] (6) Forming the hollow bicycle assembly. [0009] However, the lateral rigidity (torsion rigidity) of the bicycle components made by the above-mentioned molding method is relatively insufficient, so the bicycle head tube made by the above-mentioned molding method limits the handli...
