Description

The manufacture method of wooden shaft-like sports requsites

Technical field

The present invention relates to a kind of manufacture method of wooden shaft-like sports requsites.

Background technology

The manufacture method of existing wooden billiard stick sees also Fig. 1 and Fig. 3, and its step is as follows:

1, makes wooden core bar 81: take a wooden core bar 91 with major axis and one first external diameter;

2, coat the made clad 82 of a fiber cloth by pre-soaked resin (Resin Dipped Cloth): cut earlier and be wound in this wooden core bar 91 again, and form a clad 92;

3, cover covers intermediary's material 83: intermediary's material 93 is wound in this clad outer rim;

4, add warm hardening 84: place in the heating furnace 94 and heat, make this carbon cloth hardened forming with 120 to 160 degree Celsius;

5, take off this intermediary's material 85;

6, finish finished product 86.

See also Fig. 2 and Fig. 4, the detailed manufacture process of the fiber cloth 92 of existing further this pre-soaked resin of labor, it is finished by the following step:

(1) sheet-like fiber cloth 821: obtain a sheet fiber cloth 921, fixed size can't elasticity widen;

(2) contain the curing agent 822 that resin pickup and high temperature just can react: this sheet-like fiber cloth 921 is contained resin pickup, and, add the curing agent 922 that high temperature just can react, so, just can not store, produce when selling or transporting hardening phenomenon;

(3) pre-soaked resin fiber cloth finished product 823: so, finish pre-soaked resin fiber cloth finished product, wait for and be sold to the buyer in the future;

(4) store/sell/transport 824: after manufacturing, to actual the use, all have first-class to treat the time, be statically placed in the warehouse or transport by lorry;

(5) be cut into trapezoidal 825: because general billiard stick is coniform, must be cut into one trapezoidally, the seam longitudinally 95 that it is intervolved behind this coniform wooden core bar 81 is smooth.

There is following shortcoming in above-mentioned prior art main:

[1] add warm hardening and cause wooden part bending, fraction defective is too high.Timber is natural material, and the orientation of fiber wherein, Density Distribution and inner slight void be uniformity fully all, and be particularly very responsive to temperature, in case heat to 45 to 60 degree Celsius when above, straight billiard stick can begin bending originally.Temperature is high more, and diastrophic situation is serious more, that is fraction defective improves.On the other hand, in order to enhance productivity, the high more then hardening of resin time of temperature is short more, and output is big more.So, if between 120 to 160 degree Celsius, add warm hardening in a conventional manner, produce in 20000 products, 10000 defective products (because of the hot bending distortion) are arranged approximately, fraction defective is about about 50%, though speed of production is fast, fraction defective is too high.

[2] must be cut into trapezoidally, formality is loaded down with trivial details, and only is applicable to single size, again can residual longitudinal seam.Because billiard stick is generally coniform, if outer surface will be coated, tapering is cut into trapezoidally according to this, and operation is loaded down with trivial details, and only is applicable to single size, if the diameter of another batch rod changes, then will be cut into another ladder type size.In addition, again can residual longitudinal seam 95 at joint, more not attractive in appearance.

[3] can't be applied to the special formed club of irregular surface.If external form such as the Fig. 8 or the club shape shown in Figure 9 of club then can't (or being difficult to) be cut out the pre-soaked resin fiber cloth, be of limited application.

So be necessary to research and develop new product to overcome above-mentioned shortcoming.

Summary of the invention

In order to overcome the above-mentioned shortcoming that existing wooden manufacture of ball-colliding rod exists, the invention provides a kind of manufacture method of wooden shaft-like sports requsites, it at room temperature hardens, and wooden stick's embryo is indeformable, and qualification rate is high.It cuts simple and easy, telescopic twill fiber net does not have longitudinal seam, is applicable to different-diameter or special external form, applied range are arranged.

The technical solution adopted for the present invention to solve the technical problems is:

A kind of manufacture method of wooden shaft-like sports requsites is characterized in that it comprises the following steps:

One, prepare wooden stick's embryo: processing car system one wooden stick's embryo, this wooden stick's embryo generally is the slightly straight round bar shape of tapering;
