Abstract

The present invention relates to a method for manufacturing an anti-bending billiard ball rod. Firstly, a wooden rod is turned to obtain a wooden core rod with a prearranged external diameter. Then, the surface of the core rod is coated with at least one fiber reinforced woven fabric of preliminary dip resin to form a blank rod with a proper external diameter. Subsequently, the surface of the blank rod is coated with an intermediary substance capable of generating predetermined pressure on the blank rod and used for generating pressure of a predetermined program, and the fiber reinforced woven fabric of the preliminary dip resin is enforced to be tightly attached to the surface of the core rod. After that the bland rod is heated with a predetermined temperature. Finally, the intermediary substance is taken away, and thus, the waterproof and warping preventing billiard ball rod is manufactured.

Description

Method for mfg. anti-bending billiard cue

The present invention is relevant with billiard stick, particularly about a kind of manufacture method that prevents bent change billiard stick.

As everyone knows, at present general billiard stick is to make with wood materials, because the wood materials billiard stick is subjected to climatic effect and flexural deformation easily, recently once the someone to change with fiber reinforced plastic (FRP) be material, though but its more not yielding price is too high, the not high and sense of touch when billiards of the wish of ordinary consumer use is not as wood materials, so it is core bar is coated with fiber reinforced plastic again in the core bar outside billiard stick with the wood materials that the applicant invents a kind of, this kind billiard stick can be possessed on the one hand the characteristic of wooden club and be hedged off from the outer world by fiber reinforced plastic and be difficult for being subjected to climatic effect and be out of shape, therefore, the widely popular at present usefulness of liking, and obtained the Taiwan patent of invention more No. 31228, yet this kind billiard stick then runs into some problems on making, promptly in the time of outside the core bar desire covered fiber reinforcement plastics of wood materials layers, all it is inserted heating pressurization in the mould at present, the fiber reinforced plastic of this skin can tightly be pasted and hardened forming on the surface of this core bar, yet promptly must to offer one pair of its cost of mould very high owing to make a club, and speed of production is also slow, moreover when being coated on the non-material for fiber reinforced plastic of core bar surface outer covering layer, utilizing mould and can't reach the effect that fits tightly as this.

Therefore, the present invention's main purpose is to provide a kind of bent manufacture method that becomes billiard stick that prevents, wherein include each following step: a. turning wood materials formation one has the core bar of the longitudinal axis and one first external diameter; B. reel with at least one clad and be pasted on the surface of this core bar, and form an embryo bar with second predetermined outer diameter, wherein this second external diameter is greater than first external diameter, and this clad is to have predetermined thickness, can completely cut off aqueous vapor and heat-resisting predetermined resin pickup fiber cloth; C. Jie's material cover is overlying on the surface of embryo bar among can producing a predetermined pressure to this embryo bar surface with one, and this clad can be close on this core bar; D. with a predetermined temperature that is higher than room temperature this embryo bar is heated, make this clad hardened forming; E. be overlying on the material that is situated between among this embryo bar taking off this cover after the scheduled time, can finish a complete club.

In the method for the invention, this intermediary's material can be a hollow bag in the aforementioned C step, it at first is overlying on this hollow bag cover this wooden core bar surface, secondly the air between this hollow bag and this core bar is got rid of, make it become vacuum state, so force this clad to be close on this core bar surface by the atmospheric pressure in this hollow bag outside.

In the method for the invention, this intermediary's material also can be a banded material with high-tension, heatproof in the aforementioned C step, be that it is wound on the surface of this embryo bar in regular turn during use, taken off after the moulding to be heated, tension force that therefore should the band shape material can force this coating to be close on this core bar surface again.

Below lift a preferred embodiment conjunction with figs. the present invention is done further explanation, wherein:

Fig. 1 is the manufacturing process calcspar of preferred embodiment of the present invention.

Fig. 2 is for coating the three-dimensional exploded view that one deck carbon fiber reinforcement is weaved cotton cloth in this core bar surface in the preferred embodiment of the present invention.

Fig. 3 utilizes the generalized section of atmospheric pressure to this embryo bar surface pressurization for preferred embodiment of the present invention with forming vacuum state between this hollow bag and this embryo bar.

The timber of at first taking suitable kind intercepts into predetermined length with it, be lathed then by front end toward the gradually big pushing and drawing shape in rear end, this is a core bar 1, secondly then take two layers of weaving cotton cloth by carbon fibre initial rinse epoxy resin, each layer weaved cotton cloth and gone up coating with suitable stick in this, axially become 30 °-45 ° mode to be coated on the surface of this core bar in regular turn and to form a clad 2 with fiber orientation and this core bar then, so promptly form an embryo bar 3, treat that the interior solvent evaporates of the clad 2 of this embryo bar 3 is after to a certain degree, the plastic tube bag 4 of taking a hollow is inserted in this embryo bar 3 in its bag, and then with suitable utensil with the state that is evacuated within this hollow plastic bag, can make clad can tightly be covered on the surface of this core bar 1 this moment by atmospheric pressure to this embryo bar surface pressurization (shown in Fig. 3 direction of arrow); Certainly, the present invention's embryo bar also can be gone up the PVC plastic tape that twines with high-tension in its surface, can utilize the tension force of this plastic tape to make its clad can be covered on the surface of this core bar tightly to this embryo bar pressurization; After finishing aforementioned step, again this embryo bar 3 is inserted in the heating furnace with 120 ° of-160 ℃ of heating, make this carbon-fiber cloth hardened forming, treat a period of time after, this embryo bar 3 is taken out and unloads this plastic tube bag 4, promptly finish a complete billiard stick this moment.

Claims

1, a kind of manufacture method that prevents bent change billiard stick comprises following step:

A. turning one rod forms a wooden core bar with major axis and one first predetermined outer diameter;

B. be wound on the surface of this core bar with one deck clad at least, in order to form an embryo bar with second external diameter, wherein this second external diameter is greater than this first external diameter, and this clad is made by the fiber cloth of pre-soaked resin;

It is characterized in that further comprising the steps of:

C. be overlying on this embryo bar surface with Jie's material cover among can producing a predetermined pressure to this embryo bar surface;

D. with a predetermined temperature that is higher than room temperature this embryo bar heating is made its clad hardened forming;

E. take off this cover material that is situated between among being overlying on this embryo bar, promptly finish a complete billiard stick.

2, manufacture method according to claim 1, it is characterized in that: Jie's material is a hollow bag among in this C step, it at first is that this hollow bag cover is overlying on this wooden core bar surface, extract the air between this hollow bag and this core bar then, atmospheric pressure by means of this hollow bag outside can produce pressure to this embryo bar surface, forces this clad to be close on this core bar surface.
