Description
The present invention relates to the method for making and the manufacturing installation of racket, particularly relate to a kind of method for making and manufacturing installation of making racket with carbon fiber.
Existing method for making and the device of making carbon badminton racket, envelope a match Lopa Nationality airduct (12) (but nylon hose of high temperature high voltage resistant) (as shown in Figure 1) manually carbon-fiber cloth (11) is reeled earlier, the match Lopa Nationality airduct that again this is wound with carbon fiber is inserted a molding chamber (13) (as shown in Figure 2), be blown into this match Lopa Nationality airduct (12) with pressure-air behind the matched moulds, rely on the inner pressure-air of this airduct (12) to make its outer field carbon-fiber cloth (11) attach firmly die cavity (13) inwall closely, the resin solidification typing that this carbon-fiber cloth of chien shih includes when predetermined heat, promptly form the thick embryo (as shown in Figure 3) of required racket (15), because match Lopa Nationality airduct (12) only can be made the flexible pipe of same size, and it is big to make conical pipe or one section, one section little not equal section flexible pipe, so Badminton racket axis (16) and shank (18) can't be one-body molded, existing method is match Lopa Nationality airduct (12) the coiling carbon-fiber cloth (11) that is slightly less than Badminton racket (15) axis (16) section radius with, again it is inserted in the die cavity (13), the frame portion (17) of one-body molded racket and axis (16), the shank of racket (18) then after frame portion (17) and axis (16) are one-body molded more in addition installing get on.
Above-mentioned manufacture method because the shank (18) of racket is to stick to axis (16) lower end separately, is not only made and is gone up many one formalities, and shank (18) has the anxiety that comes off and separate with axis (16) after using a period of time simultaneously; Moreover, because match Lopa Nationality airduct (12) is a soft nylon tube, be again to curl when coiling carbon-fiber cloth (11) with artificial, can make this nylon hose produce fold unavoidably, therefore when being blown into gases at high pressure the fold of this nylon hose some can't stretch and the tube wall that forms flexible pipe is overlapped, the airduct of exerting pressure in the tube wall when this phenomenon will cause the racket moulding (12) wall unevenness, because the resin that carbon-fiber cloth (11) includes has flowability before uncured, this airduct (12) internal high pressure gas will force this airduct (12) to push this carbon-fiber cloth (11) distortion and make this airduct (12) inwall form approximate proper circle face, the fold tube wall of this airduct (12) will be clamp-oned in this carbon-fiber cloth (11) layer, flow around the resin that this carbon-fiber cloth layer (11) is included is past, cause the racket section inequality after the moulding, thin its resin content of person of section is less, rigidity strengthens and elasticity weakens, make its structure embrittlement and easy fracture, especially in axis (16) structure of racket, because all stress of square stance all will be conducted by axis, so its pressure and deflection deformation are maximum positions at whole racket, if its structure embrittlement is what for easily portion's be full of cracks thus.
For solving aforementioned first shortcoming, the inventor once developed and a kind ofly interconnected with different tube diameters match Lopa Nationality airduct, to form stepped body, the axis of one-body molded racket and the method for making of shank that section configuration differs.But still have following binomial shortcoming.At first, its air blowing is to be introduced into the tubule footpath section that the big caliber section of shank flows into axis and frame portion again, gases at high pressure enter the tubule footpath section that big caliber section flows into axis and frame portion again, gases at high pressure enter after the big caliber section because the section of runner amplifies suddenly, flow velocity slows down immediately, so that being blown into the air pressure and the air-flow of tubule footpath section all weakens, therefore the racket with these mode moulding is that its shank reaches the maximum pressure that is blown into gas earlier, be this axis again, be only this frame portion at last, so the structure of its shank is better than this axis after the moulding, this axis then is better than this frame portion, however the use of racket, and its structure should be most important with frame portion and axis, this shank then takes second place, and aforementioned blowing moulding mode is run counter to desire.Next will connect into an intercommunication with the match Lopa Nationality airduct of two different tube diameters and gastight airduct is not easy, if airduct gas leakage, then carbon fiber can't be shaped by inflation in pressing mold, and whole carbon cloth all will be scrapped, and its cost is quite high.
