Abstract
The racket frame is made up of thermoplastic composite material through finishing yarn, wetting, winding, moulding and cooling and features one-pass completion of making fibrous body of racket frame and reinforcing, so simplifying process, and improving its quality.
Description
The present invention relates to a kind of method for making of thermoplastic composite racket frame.
The making of existing thermoplastic composite racket frame is that nylon yarn and carbon fibril dimension are wound in continuity bundle fiber material cell or directly are stained with mixed powdery nylon material by the pencil carbon fiber wire, warp loom is woven into a cover tubular and knits pipe again, then getting some pipes of knitting again cooperates a central siphon to wear mutually to become to knit the pipe layer, and at the desired area reinforcing chip that is sticked, to knit the pipe stratification at last and go into that heating makes contained nylon yarn fusing, flows in the mould, be cooled to a racquet frame then.The method for making of this thermoplastic composite racket frame has following weak point: be the nature loose condition (of surface) owing to bundle fiber in the manufacturing process, its fibre single thread angle in the braiding process can't be fixed, boundling becomes thigh easily to twist, can't smoothly flatten, when machine-shaping is racquet frame, though HTHP also is difficult to make yarn Shu Zhankai, so that the racquet frame inwall of institute's moulding has the cave, causes stress to concentrate and reduces frame intensity.In addition, the braiding of knitting pipe adopts two prescriptions to around volume, and therefore, the reinforcement angle is subjected to very big restriction, must utilize the higher pipe suitable cover of axle and cooperate aforementioned reinforcing chip to be built up with various angles mutually of knitting, and therefore, manufacturing process wastes time and energy, and wastes raw material.
The present invention is intended to propose the method for making of the time saving and energy saving thermoplastic composite racket frame of a kind of manufacturing process, to overcome the deficiency of existing method for making.
The method for making of the thermoplastic composite racket frame that the present invention proposes comprises following steps:
The first, whole yarn.With thermoplastic and carbon fiber compound after, accumulate a material cell respectively by predetermined number of share of stock.
The second, moistening.The previous materials unit soaked to eliminate fiber weekly form fine, soft fur make it not loose.
The 3rd, reel.With aforementioned moistening composite unit respectively winding put at the interlayer of a mandrel, and change winding directions, until obtaining a hollow form fiber body by various predetermined angulars.
The 4th, the pre-type of mould.The bending of above-mentioned hollow form fiber body is inserted in the racquet frame mould, and heating makes thermoplastic melt even filling to be wrapped between carbon fiber.
The 5th, cooling forming.Make thermoplastic solidify the formation racquet frame mould cooling.
Because the method for making of the hot plastic type racquet frame that the present invention proposes by " coiling " step, can be operated inferior finishing with racquet frame main body and reinforcement, makes prepared racquet frame quality improve, and time saving and energy saving.
Below in conjunction with drawings and Examples the present invention is further described.
Fig. 1 is the making flow chart of the embodiment of the invention.
Fig. 2 is the whole yarn schematic diagram of the embodiment of the invention.
Fig. 3 is the operating winding schematic diagram of the embodiment of the invention.
Fig. 4 is the hot briquetting schematic diagram of the embodiment of the invention.
With reference to Fig. 1,, comprise following making step as embodiments of the invention: the first, whole yarn; The second, it is moistening to soak; The 3rd reels; The 4th, the pre-type of mould; The 5th, cooling forming.Wherein,
Whole yarn step, as shown in Figure 2, choose thermoplasticity wire rod and the synthetic continuous bundle fiber material cell 1 of carbon fiber such as nylon wire, and reel 3 is set on a yarn positioning machine table 2, be used to put the fiber material unit, can adopt two one group according to need, or three, or the end line that the tetrad reel will be put in order volume material unit 1 then causes the material unit 11,12 that is merged into bigger bundle on the whole yarn machine 4,13,14.Soak moistening step as shown in Figure 2, with the big material unit 11 behind the whole yarn of aforementioned polymerization, 12,13,14 immerse respectively in the tank 5, also the aqueous solution can be sprayed at big material unit 11 with spray pattern, 12, to reach wettability effect, make each single be wetting state and unlikely loose on 13,14.
The coiling step as shown in Figure 3, the interlayer that the aforementioned material unit that has soaked is set around on coiling machine 6 axles 61 overlaps on 62, utilize interlayer cover 62 to supply aforementioned material (11-14) to twine, the parallel driving screw 63 that is pivoted in axle 61 the place aheads, its axial spiral shell is established a sliding seat 64, there is a breach 65 to stride on this sliding seat and sets the position for fiber material, because of sliding seat 64 is made axial translation with the rotation of driving screw 63, so form a predetermined angular with this axle 61, axial displacement along with sliding seat 64, can overlap the reinforcing fiber of the various angles of winding on 62 at interlayer, be equivalent to tradition and knit the effect that pipe adds reinforcing chip and wears middle pipe.Wherein the coiling principle of material unit as shown in Figure 3, the rotating speed of establishing axle 61 is W, and axle the move speed of sliding seat 64 on driving screw 63 is V, make W very fast, and V is slower, then winding angle trend 90 degree; Otherwise then tend to 0 degree, and be various angles in the centre, because of moistening, comparatively fit between fiber through soaking, so can form the fibrage of higher density, its extensibility is good, with layer sand different angles can be arranged, and need not manually slowly fit fully, therefore, the angle orientation of yarn is good, and need not can once finish rectangular fibre pipe 7 with sleeve pipe, as shown in Figure 4.
The pre-type step of mould is taken out the aforementioned rectangular fibre pipe of finishing 7 and is inserted in the racquet frame mould 8 on axle 61, heating makes thermoplastic (as nylon) fusion and then carbon fiber all can be wrapped up and be full of entire die inside.
Cooling step waters water for cooling with mould 8, makes wherein that thermoplastic solidifies, and die sinking can be taken out the finished ball frame.
Above-mentioned preparation method is not only simplified technology significantly, shorten man-hour, also obtain preferable intensity because of continuity fiber and intensive are high simultaneously, its axle outside dimension is easy to control accurately, need not resemble to do the prior art and cut out the yarn step, thereby can save manpower and raw material in a large number.
