Abstract

The utility model discloses a carbon-fiber golf club body. A center hole of the carbon-fiber golf club body is a round hole, and raised lines are formed on the inner wall of the center hole. The raised lines formed on the inner wall of the center hole of the golf club body have effects of reinforcing ribs, so that the bending resistance and the torsion resistance of the golf club body are increased, and batting effect is improved.

Description

A kind of carbon fiber golf ball bar body

Technical field

The utility model relates to the technical field of golf clubs, particularly a kind of carbon fiber golf ball bar body.

Background technology

Golf clubs is made up of shaft, bulb and handle.In the prior art, shaft adopts carbon fiber to make usually.Carbon fibre material is coated on the plug, puts into the die cavity of mould again, carbon fiber is solidified, take out the coring rod after the demoulding again, promptly make the carbon fiber golf ball bar body through heating.Because plug is a round bar, and the round bar smooth surface is complete, so, the centre bore of the carbon fiber golf ball bar body of making is a circular hole, and shaft thickness is even, consistent, be assembled into golf clubs after, the anti-bending strength of shaft and torsional property are all relatively poor, balling effect is also relatively poor, is further improved really.

The utility model content

The purpose of this utility model provides a kind of carbon fiber golf ball bar body, to improve the anti-bending strength and the torsional property of shaft, improves balling effect.

In order to reach above-mentioned purpose, solution of the present utility model is:

A kind of carbon fiber golf ball bar body, its centre bore is a circular hole, forms raised line on the center bore inner wall.

Form three on the described center bore inner wall to six roots of sensation raised line.

Described raised line is tapered to small end from the big end of club.

After adopting such scheme, the utility model is because form raised line on the inwall of shaft centre bore, and this raised line plays a part reinforcement, makes the anti-bending strength of shaft and torsional property improve, thereby has improved balling effect.

Carbon fibre material 6 BOPP films 7.

The specific embodiment

Below in conjunction with the drawings and specific embodiments the utility model is further described.

Referring to illustrated in figures 1 and 2, a kind of carbon fiber golf ball bar body that the utility model discloses, its centre bore is a circular hole, forms raised line 1 on the center bore inner wall.The radical of raised line 1 is not limit, and is advisable to the six roots of sensation with three, and this embodiment has three raised lines 1.Raised line 1 is tapered to small end from the big end of club.

The forming method of the utility model carbon fiber golf ball bar body is as follows, cooperates Fig. 3 and shown in Figure 4:

Select round mandrel 2 earlier, plug 2 surfaces have the groove 21 that is used to form raised line 1; Off-shape agent and resin on the mandrel surface;

Then, in the groove 21 of plug 2, put into carbon-fibre strips 5;

Again carbon fibre material 6 is coated on the plug 2, and winding one deck BOPP film 7 is a bidirectional stretching polypropylene film on carbon fibre material 6, afterwards, puts into the die cavity that patrix 3 and counterdie 4 form together;

Then, heating is solidified carbon fiber under 130 ℃, and carbon-fibre strips 5 and carbon fibre material 6 merge;

At last, coring rod 2 is taken out in the demoulding, takes off BOPP film 7, the carbon fiber that is coated on the plug 2 solidify to form shaft, and the carbon-fibre strips in the groove 21 solidify to form raised line 1, and surface grinding is handled, the blank product examine, japanning is promptly finished carbon fiber golf ball bar body of the present utility model thus.

The utility model plays a part reinforcement at the raised line 1 that the shaft inwall forms, and makes the anti-bending strength of shaft and torsional property improve, thereby has improved balling effect.With different angles and bulb winding, make raised line 1 be positioned at the diverse location of bulb shaft, can be at different balling effects.

The foregoing description and graphic and non-limiting product form of the present utility model and style, any person of an ordinary skill in the technical field all should be considered as not breaking away from patent category of the present utility model to its suitable variation or modification of doing.
