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
The present invention relates to a kind of forming method of bicycle assembly, particularly relates to a kind of forming method of reinforced carbon fiber bicycle component.
Background technology
As shown in Figure 1, the forming method of a bicycle assembly was to be applicable to the bicycle assembly of making a hollow in the past, and may further comprise the steps:
(1) carbon fibre material is set around a mandrel surface;
(2) take out this mandrel;
(3) airbag is inserted in this carbon fibre material;
(4) this carbon fibre material is heated and, make this carbon fibre material hardened forming the inflation of this airbag;
(5) take out this airbag; And
(6) form the bicycle assembly of this hollow.
; utilize the made lateral rigidity that bicycle assembly had (torsional rigid) of above-mentioned forming method not enough; therefore; utilize the made bicycle head tube of above-mentioned forming method to limit the handling of cycle frame; utilize the made bicycle five-pipe of above-mentioned forming method then to limit the explosive force of cycle frame, so still have the space of improvement.
Summary of the invention
Therefore, purpose of the present invention is promptly at the forming method of the reinforced carbon fiber bicycle component that a kind of lateral rigidity that can improve bicycle assembly is provided.
So the forming method of reinforced carbon fiber bicycle component of the present invention is to be applicable to make a bicycle assembly, and may further comprise the steps:
(1) make hollow foaming material mandrel: utilize expanded material to make the mandrel of a hollow and thin-walled, this mandrel has at least one forming tank that is formed at the surface;
(2) carbon fiber is wound in mandrel: be arranged at this mandrel surface with one from the shape layer, carbon fibre material be set around this from the shape laminar surface again;
(3) mandrel support the location: an airbag is inserted in this mandrel, in order to support this mandrel of location;
(4) the thick embryo of extrusion forming of heating: with this airbag inflation, and this carbon fibre material and this mandrel heated and pressurize, make this carbon fibre material hardened forming; And
(5) take out carbon fiber hollow assembly: take out this airbag and this mandrel, the carbon fibre material behind the hardened forming promptly becomes this bicycle assembly at this moment.This bicycle assembly is a hollow, and has and at least onely be formed at inner circumferential surface and corresponding to the reinforcement rib of this forming tank.
Because this mandrel has at least one forming tank that is formed at the surface, so the bicycle assembly that completes at last has at least one reinforcement rib that is formed at inner circumferential surface, can promote the lateral rigidity of this bicycle assembly effectively, and then promote the handling and explosive force of cycle frame.
Description of drawings
Fig. 1 is a flow chart of the forming method of a bicycle assembly in the past;
Fig. 2 is the flow chart of preferred embodiment of the forming method of reinforced carbon fiber bicycle component of the present invention;
Fig. 3 is a three-dimensional combination figure of this preferred embodiment, and the structure of the mandrel of a hollow and thin-walled is described; And
Fig. 4 is another three-dimensional combination figure of this preferred embodiment, and the three-dimensional cutaway view of a bicycle assembly is described.
The specific embodiment
The present invention is described in detail below in conjunction with drawings and Examples:
Shown in Fig. 2,3,4, the preferred embodiment of the forming method of reinforced carbon fiber bicycle component of the present invention is to be applicable to make a bicycle assembly 1, and may further comprise the steps:
(1) make hollow foaming material mandrel: utilize expanded material to make the mandrel 2 of a hollow and thin-walled, this mandrel 2 has most the forming tank 21 that are formed at the surface.This expanded material can be polystyrene foam, polyurethane foaming material, and epoxy foaming material, all can reach identical effect.In addition, the thickness of this mandrel 2 is between between 1mm to 10mm;
(2) carbon fiber is wound in mandrel: be arranged at this mandrel 2 surfaces with one from the shape layer, carbon fibre material be set around this from the shape laminar surface again.Waiting to heat after the extrusion forming, should be in order to help this carbon fibre material to separate with this mandrel 2 from the shape layer;
(3) mandrel support the location: an airbag is inserted in this mandrel 2, in order to support this mandrel 2 of location;
(4) the thick embryo of extrusion forming of heating: with this airbag inflation, and this carbon fibre material and this mandrel 2 heated and pressurize, make this carbon fibre material hardened forming.Wherein, the temperature of heating is between 120 ℃ to 170 ℃, and the pressure of pressurization is between between 6kg/cm2 to 17kg/cm2, and is preferable, and the temperature of heating is between 145 ℃ to 155 ℃, and the pressure of pressurization is between between 12kg/cm2 to 15kg/cm2; And
(5) take out carbon fiber hollow assembly: take out this airbag and this mandrel 2, the carbon fibre material behind the hardened forming promptly becomes this bicycle assembly 1 at this moment.This bicycle assembly 1 is a hollow, and has most the reinforcement ribs 11 that are formed at inner circumferential surface and correspond respectively to described forming tank 21.In the present embodiment, because this mandrel 2 can produce contraction and separate with this bicycle assembly 1 after heating, therefore the user can take out this mandrel 2 after heating, but the user takes out this bicycle assembly 1 after also can utilizing butanone with these mandrel 2 dissolvings earlier again, not as limit.
Described reinforcement rib 11 is when heating and pressurizeing with the inflation of this airbag and to this carbon fibre material and this mandrel 2, enters described forming tank 21 because the part carbon fibre material is under pressure and forms.Therefore, the user can be formed at the distribution scenario of the forming tank 21 on these mandrel 2 surfaces by design before processing procedure begins, and controls the formation position of the reinforcement rib 11 that is formed at this bicycle assembly 1 inner peripheral surface, promotes the lateral rigidity of this bicycle assembly 1 whereby.
In addition, because the mandrel 2 of this hollow and thin-walled is to utilize expanded material to be made, so visual demand is shaped to different shape, to make different types of bicycle assembly, for example head pipe, five-way pipe, wheel rim etc.
In sum, because this mandrel 2 has most the forming tank 21 that are formed at the surface, so the bicycle assembly 1 that completes at last has most the reinforcement ribs 11 that are formed at inner circumferential surface, can promote the lateral rigidity of this bicycle assembly 1 effectively, and then the handling and explosive force of lifting cycle frame, so can reach purpose of the present invention really.
