Abstract

The present invention relates to a manufacturing method of a club head of a wooden golf club. Firstly, a hollow wooden club head is made of metal and is provided with a metal top cover. After that a casing of the club head is used as a mould, composite material is attached on the top cover of the casing of the club head to form a thin composite material top cover which forms the shape of the top cover of the club head. The composite material top cover is disassembled, and a through hole is cut in the position of the top cover of the casing of the metal club head. The shape of the through hole is similar to the shape of the composite material top cover, but has a smaller dimension. Finally, the composite material top cover is attached to the top surface of the casing of the metal club head and covers the through hole.

Description

The method for making of golf club head

Technical field

The present invention relates to a kind of method for making of golf club head, particularly make about a kind of bar head capsule body and function metal, and the method for making of the hollow club head that top cover is made with the composite shell.

Background technology

Golf club head all is to require center of gravity low in design as far as possible, makes farther that ball can hit, and for the hollow metal club head, all is as far as possible top cover is done thin more light more in design therefore, and its effect is good more.Because the proportion of metal is higher, therefore in lightweight, always be not so good as directly to adopt the effective of composite.Yet between composite top cover and the metallic rod head capsule body is to engage by sticker (for example epoxy resin), unless can closely connectedly fully have no the warpage slit between composite top cover and the metal shell that the institute desire engages, otherwise must have internal stress after fitting produces, even basic subsides are not got up, there is the bar head of internal stress this kind applying position when bearing powerful batting back generation flexural deformations, as easy as rolling off a log phenomenon of breaking in the applying position.Because no matter metallic rod head capsule body is with accurate lost wax casting, or be welded with 2 or 3 metal parts, it treats that the position that engages with the composite top cover always can be because of the dimensional contraction tolerance, the micro-strain that the carrying of raw material object storehouse causes, welding process, surface grinding processing procedure etc. cause each metal shell not have on all four applying position, even therefore produce the composite top cover with the most accurate condition model, also be difficult to coincide, also just can't remove the internal stress of applying position with each metal shell.

Summary of the invention

At the problems referred to above, main purpose of the present invention provides a kind of method for making of golf club head, and it can make the bar head that composite top cover and metallic rod head capsule body fit like a glove and amplexiform.

For achieving the above object, the method for making of a kind of golf club head provided by the present invention, its technical characterstic is: make a hollow club head with metal earlier, the bar head has had casting coping, be mould with bar head capsule body then, on the top cover of composite attached to bar head capsule body, mold a composite shell top cover, take off this composite top cover, top cover position at metallic rod head capsule body cuts out a perforation, then the composite top cover is fitted in the end face of metallic rod head capsule again with sticker, and covers above-mentioned perforation, so promptly finish one and make the hollow metal club head of top cover with composite.And because the composite top cover is originally to make moulding as mould with the metallic rod head capsule body of its applying, to fit fully closely so can guarantee the metallic rod head capsule body that each sheet composite top cover all must be corresponding with it.

The specific embodiment

Be elaborated for an embodiment and conjunction with figs. below.

As shown in Figure 1, the method for making of golf club head provided by the present invention includes the following step:

Steps A: get the raw materials ready, produce a hollow rod metallic rod 10 earlier and the fibrous reinforcement sheet stock that carbon fiber contains epoxy resin dipping is cut into reservation shape 20 '.Wherein metallic rod 10 can be a lost wax casting, or forging some lamellar bodies is welded again, and the fibrous reinforcement sheet can be carbon fiber, glass fibre or boron fibre or the like.

Step B: ready fibrous reinforcement sheet stock 20 ' is overlayed on the end face of metallic rod head capsule body 10, and this step is because sheet stock 20 ' contains and is soaked with resin, so sheet stock 20 ' can be attached to metal shell 10 end faces.

Step C: with the bar head of adhesive tape 30 winding step B, the sheet stock 20 ' that fiber is contained resin pickup overlays with metallic rod 10 closely.The adhesive tape of Shi Yonging is identical with the outer coating adhesive tape of moulding carbon fiber axostylus axostyle (for example golf axostylus axostyle or fishing rod) herein.

Step D: the bar head of step C is inserted heating in the baking box 40, make the epoxy cure typing.

Step e: from the baking box 40 of step D, take out the bar head, and untie the outer adhesive tape that coats.

Step F: the composite top cover 20 that will finalize the design separates with metallic rod head capsule body, and cuts out a perforation 11 at the end face of metallic rod head capsule body 10.

Step G: top cover 20 is covered back metallic rod head capsule body 10 end faces, and engage with sticker (for example epoxy resin).

Step H: several are inserted in the polybag 50 with the bar head of step G, and bar head 10 neck end are overlapped 12 blockings with an end.

Step I: the polybag 50 of step H is evacuated, utilizes atmospheric pressure that top cover 20 and metallic rod head capsule body 10 are overlayed.

Step J: the object of step I is inserted heating in the baking box 60, make the sticker sclerosis.

At last bar head 10 is taken out from baking box 60 and polybag 50, promptly obtain as Fig. 2, bar header structure shown in Figure 3.This bar head is with metal housing 10, and its end face has a perforation 11, and covers sealing perforation 11 with a composite top cover 20.Because composite top cover 20 is be the mould hardened forming with its metallic rod head capsule body 10 of being fitted directly, so can reach custom-made by size, flawless excellent effect.

Fig. 4, shown in Figure 5 for another example, bar head 70 also is to make according to preceding method, its difference is that metallic rod head capsule body 70 is being positioned at toe 71 and heel 72 positions, respectively extend to form a crack 74 by end face perforation 73 toward both sides, composite top cover 80 then correspondence respectively extends a shoulder 81 toward both sides, is used for coating covering each crack 74.The structure of this kind bar head 70 can further alleviate the weight of metal shell, moreover is to connect with composite between the side before and after the metal shell, has bigger strain elasticity after making the batting of bar head, can effectively promote the usefulness of batting and ball-handling.In addition, two shoulders 81 of top cover 80 are C type clip form and envelope bar head capsule body both sides, make the intensity of its combination higher.In addition, crack 74 also may extend to the bottom (sole) of metallic rod head capsule body, and two shoulders 81 also extend coated to the bottom surface relatively, and this measure is loss of weight and increase bending elasticity between forward and backward two sides of bar head further.
