Abstract

The invention relates to a forming method of holes in a bicycle frame or a fitting made from composite materials of a bicycle, and finished products of the holes. The forming method mainly comprises the steps that bosses are arranged portions, corresponding to hole forming positions of the bicycle frame or the fitting, on the surface of a basic modeling body, carbon fiber cloths with notches, corresponding to the bosses of the basic modeling body, are used for wrapping the surface of the basic modeling body, the carbon fiber cloths are piled into layers to a preset thickness, then the basic modeling body wrapped with the carbon fiber cloths is put in a mold, after blowing, hot pressing, curing and shaping, the basic modeling body is withdrawn, and the bicycle frame or the fitting with holes and made from the composite materials of the bicycle is completed. The forming method disclosed by the invention has the efficacies of saving processing man hour and reducing cost.

Description

The forming method in the hole of bicycle composite vehicle frame or accessory and finished product thereof

[technical field]

The present invention is about a kind of bicycle composite vehicle frame or the forming method in the hole of accessory and finished product thereof, Espespecially this hole can be the most one-body molded with bicycle composite vehicle frame or the molding of accessory, improves known being somebody's turn to do Hole need again by clamping mould and milling machine Drilling operation begin can molding, there is saving machining period and cost-effective Effect.

[background technology]

The bicycle output value in recent years is considerable, make the most at short notice bicycle vehicle frame or One of target that accessory, always bicycle industry are pursued, the vehicle frame of current bicycle or accessory generally with Carbon fiber or metal (such as aluminium alloy, titanium alloy, magnesium alloy) are made；The especially vehicle frame of carbon fiber or accessory Advantage be: lightweight, impact good absorbing, can make variously-shaped.But, carbon fiber bicycle frame or join Part needs providing holes, such as string holes or screw etc., such hole arrange known manufacture be this carbon fiber bicycle frame or After accessory molding, the another clamping mould that manufactures clamps this carbon fiber bicycle frame or accessory, carries out on milling machine machinery Being drilled with of hole, if screw processes through tapping again.Known carbon fiber bicycle frame or the accessory manufacture to hole, Not only take a lot of work, and cost is high, to be improved.

[summary of the invention]

It is an object of the invention to provide this hole a kind of can with bicycle composite vehicle frame or the molding of accessory, The most one-body molded, to save machining period and cost-effective bicycle composite vehicle frame or the hole of accessory Forming method and finished product.

For reaching above-mentioned purpose, the forming method in the cycle frame of the present invention or the hole of accessory comprises following step Rapid:

Step 1. manufactures a basis molding body, and the hole of this moulding surface, basis correspondence vehicle frame or accessory arranges place There is this aperture, hole of cooperation and boss outwardly；

Step 2. in this external surrounding phase of basis moulding to should lug boss position have carbon cloth jaggy；And

This, to after predetermined thickness, is completed carbon fiber by this basis moulding external side this carbon cloth of lamination of step 3. This basis molding body of cloth cladding puts into a vehicle frame or accessory die, after air blowing, hot-press solidifying sizing, This basis molding body is extracted out, i.e. completes this composite vehicle frame with hole or accessory.

Wherein, this hole is screw, is to process through tapping again.

A kind of bicycle composite vehicle frame or accessory, the hole on its surface be according to described cycle frame or Obtained by the forming method in the hole of accessory.

Advantage of the present invention and effect are: the present invention is set by the hole of basis moulding surface correspondence vehicle frame or accessory The place of putting is provided with boss, then when this moulding surface, basis being carried out lamination with carbon cloth, because of carbon cloth pair Should have breach at the boss of basis molding body, be stacked to predetermined thickness with carbon cloth in basis moulding is external Degree, then this basis molding body is put into mould, after air blowing, hot-press solidifying sizing, by basis molding body Extract out, i.e. complete bicycle composite vehicle frame or the hole of accessory, save be known as boring need to be to clamp mould Location vehicle frame or accessory, then the work consuming disappearance in hole is milled out with milling machine.

[detailed description of the invention]

Please refer to shown in Fig. 1-3, the hole 10 of the cycle frame 1 of the embodiment of the present invention is a string holes, Wherein, the forming method in the hole 10 of this vehicle frame 1 comprises the steps of

Step 1. manufactures basis molding body 11 (head pipe is as shown in Figure 3), and this basis molding body 11 is right Should hole 10 place of setting of cycle frame 1 have this aperture, hole 10 of cooperation and boss outwardly 12 (as Shown in Fig. 2)；

Step 2. in this basis molding body 11 surface with at the boss 12 of this basis molding body 11 corresponding have The carbon cloth 13 of jagged 14 carries out being coated with (as shown in Figure 4)；And

This carbon cloth 13 is stacked to predetermined thickness by step 3., and this is completed the base that carbon cloth 13 is coated with Plinth molding body 11 puts into a vehicle frame mould, after air blowing, hot-press solidifying sizing, by basis molding body 11 Extract out (as shown in Figure 4), i.e. complete the cycle frame 1 with hole 10.

Referring to shown in Fig. 1, Fig. 5 a, Fig. 5 b and Fig. 5 c, the embodiment of the present invention is bicycle accessories, should Bicycle accessories is a seat pipe 2, and wherein, the hole 20 of this seat pipe 2 is a string holes, and the forming method in this hole is such as As described in forming step shown in Fig. 1, basic molding body 11 surface of this seat pipe 2 and the position of corresponding aperture 20 The place's of putting evagination has boss 12 (as shown in Figure 5 a), and the side face surrounding phase in this basis molding body 11 is corresponding afterwards Boss 12 position has a carbon cloth 13 of breach 14, after being stacked to predetermined thickness (as shown in Figure 5 b), This is completed the basic molding body 11 that carbon cloth 13 is coated with and puts into a seat pipe mould, through blowing air and heat by heir After cured sizing, basis molding body 11 is extracted out, i.e. complete there is the bicycle saddle tube 2 in hole 20 (such as figure Shown in 5c).
