Description

The manufacture method of ultrabig golf club head

The present invention relates to a kind of manufacture method of ultrabig golf club head.

So golf attracts people, be that mainly the athletic ground is that the scape of making of glossy and green meadow collocation different terrain changes, make the batting that swings that people can be relaxed and joyful, the light crisp bump sound that is sent when especially meeing golf makes players find pleasure in it especially.And the personage who is familiar with golf all knows, golf clubs is because of the landform and the purposes difference in place, and has the club head of several different types, as rod head (woodclub), iron club (iron club) and push rod cup (putter club) etc., the wherein manufacturing of rod head (wood club), usually all produce a body with metal material, on body, hit panel with the welding means again in conjunction with one, design and manufacturing because of glof club head, certain specification and restriction are all arranged on size and weight, can make glof club head when hitting, bring into play the ball-handling of its expection, therefore, the manufacturer is real to be difficult at the effect that improves batting average, and increase the area of hitting panel merely, because in case the area of hitting panel increases, then the volume of body must increase relatively, to cause the overall weight of club head to increase like this, cause user's hand to grip the burden of square stance, so how to produce the light weight glof club head that can help the user to improve batting average, promptly become a big problem of glof club head manufacturer research and development.In addition, glof club head also had following disappearance on making in the past, was worth improving:

1. welding is difficult for:

Because glof club head utilized fully manually with hitting panel and body solder bond in the past, and artificial welding is subject to operating personnel's factor affecting such as mood, physiology, process technology and fluency, the glof club head quality that easily causes each welding to finish differs, cause such as hitting panel and produce broken hole, or produce unnecessary accumulation of wlding or foot phenomenon not in the hitting panel joint, cause follow-up grinding operation is produced sizable puzzlement.

2. operating speed is slow:

Glof club head be owing to must implement welding rod with manual type and weld and finish in the operation of winding hitting panel in the past, so operating speed is slower, and factors such as personnel's mood, physiology, process technology and fluency, cause production capacity to differ.

3. the welding material of Shi Yonging is limited:

Because glof club head can be made by titanium alloy, stainless steel and aluminium alloy or the like material, therefore with the body of club head relative welding material must be arranged if be used to weld the knot hitting panel, could and be consolidated the mutual fusion of described panel, with the titanium alloy material, just must use titanium welding material, the effectiveness of winding can be arranged, and rare alternative welding material, so glof club head was when welding in the past, employed welding material is very limited.

4. the glof club head color after the moulding is comparatively dull:

Still continuous described, to constitute the described hitting panel solder bond of glof club head because of desire, must there be relative welding material just can make the mutual fusion of body of hitting panel and club head and be consolidated, so that the welding material that uses is required to be identical material, so its metallic luster is also identical, cause the glof club head color after the moulding comparatively dull, and do not have the variation on the metallic luster.

The object of the present invention is to provide a kind of area super large that makes glof club head after the moulding have the light weight and the scope of attack, and the manufacture method of the ultrabig golf club head of effect such as change color is more polynary.

According to above-mentioned purpose, the manufacture method of ultrabig golf club head of the present invention, include following steps in regular turn: first embryo forming, be with the integrally manufactured germule that goes out to have the scope of attack, bar neck and bottom surface of metal material, and make the described scope of attack, bar neck and bottom surface be arranged with a filling space that is open shape; Pasting, is that the carbon fibre initial rinse fabric with extension characteristics is counted in the filling space inwall that laminating is overlying on germule, and makes carbon fibre initial rinse fabric such as described and be arranged with the enclosure space of a hollow form; Become embryo forming, be on the last carbon fibre initial rinse fabric that is covered on the germule sidepiece, to offer a hand-hole, and one airbag is filled in the enclosure space that is made of several layers of carbon fibre initial rinse fabric by described hand-hole, described airbag also is connected with a valve head, afterwards, described germule is placed in the mould, described mould is by separable public affairs, the master mold be combined into, by described valve head gas is injected described airbag again, airbag is expanded, till the complete driving fit of die cavity of the described carbon fibre initial rinse fabric outside wall surface of airbag outside and mould, add hot work simultaneously, so that described carbon fibre initial rinse fabric typing and constitute into embryo; The demoulding is to open last mould male and female mould earlier, to take out into embryo, takes out airbag then; And Surface Machining, be to add a capping in described one-tenth embryo sidepiece hand-hole place, and give grinding, the Surface Machining such as polishing, application that are carried out to embryo surface simultaneously modify operation.

The manufacture method of ultrabig golf club head of the present invention has following advantage: the glof club head after the moulding has the light weight effect: because the made glof club head of manufacture method of the present invention is metal material with light weights such as titanium alloys is made into integration except the scope of attack, bottom surface and bar neck, all the other of club head partly coat air by the lighter carbon fibre initial rinse fabric of quality especially and are constituted, therefore, the glof club head of manufacture method of the present invention institute moulding has significant light weight effect really, and club head can be developed into the example of ultra-large volume; The area super large of the scope of attack: since the present invention more in the past club head have significant light weight effect, therefore, even under the considering of good ball-handling property, club head weight is limited, the present invention still can increase the area of the scope of attack, and unlikely excessive influence increases the overall weight of club head; Glof club head change color after the moulding is more polynary: because of the made glof club head of the present invention goes out outside the scope of attack, bottom surface and the bar neck divided by metal materials such as titanium alloy are one-body molded, all the other of club head partly then coat air by carbon fibre initial rinse fabric and are constituted, therefore, in the end in the Surface Machining step of processing procedure, paint baking processing modifying carbon fibers preimpregnation cloth surface that more can different colours, it is more polynary to make that made glof club head integral color changes.
