Abstract

The utility model relates to a hollow metal head of a wooden golf club. The utility model comprises a shelly body and a pushing plate which is welded on an opening on one side on the top of the body. The utility model is characterized in that the body is cast and the pushing plate is forged; the thickness of the pushing plate which is thinner than the shelly body is thinner than 1 mm, and the thinnest pushing plate can be 0.7 mm-0.8 mm. The utility model has the advantages that the assembled head of the wooden golf club has the characteristic of low center of gravity; so a golf ball can be hit to a higher and farther place.

Description

The golf club head of tool centre of gravity characteristic

The utility model is relevant with golf driver head, particularly about a kind of golf club head of tool centre of gravity characteristic.

Golf club head now mostly is the metallic article of hollow greatly, and at present the normal a kind of method for making that adopts of industry is as follows: cast out one earlier and be the bar head shapes and the bottom surface has the shelly main body of opening, and a pair of base plate that should the main body bottom side openings.This base plate is caught close in this opening and along the base plate periphery again and welded, make the two synthetic hollow stem head, its shell meat thickness is generally between 1.5-2mm.Pressing that the design of golf driver head is many can be with its weight counterweight backward down; enable to hit ball higher farther; with regard to the shelly club head of preceding taking off; one of means promptly are that the shell sheet with bar crown face (crown) approaches as far as possible; make the bar head be the heavier centre of gravity structure in light bottom, top; yet the thickness of top side shell sheet must go out preferable effect less than the 1mm competence exertion usually; and it is quite high with the difficulty of the following shell of casting making 1mm; the shell spare deflection of casting is big; and weight wayward accurately (error range reaches about 3g); moreover; mo(u)lding often has the not good phenomenon in surface that is commonly called as " black shell ", need attrition process to be removed, and thickness is less than thin slice regular meeting's formation became uneven after grinding of 1mm again; even the possibility of breaking is arranged, reduce fine ratio of product more.To sum up, the hollow club head structure of commonly using is difficult to realize the centre of gravity characteristic.

Main purpose of the present utility model is promptly providing a kind of golf club head, and it has the characteristic of centre of gravity.

Take off purpose for before reaching, the golf club head of a kind of tool centre of gravity characteristic that the utility model provides is characterized in that, includes:

One main body forms with casting, slightly is the shape of golf club head, has a face, a bottom, a back, a toe, a heel and a neck, and this body interior hollow and be shelly, and its position corresponding to the club head top forms an opening; And

One top flat, form with metal forging, its shape is corresponding to the opening of this main body top side, and thickness is thin and is below 1.0mm than the thickness of this shelly main body, this top flat is to be covered on this opening and fixed with this main body welding, with the shape of the synthetic golf club head of this main body.

Wherein the thickness of this top flat is between 0.7mm to 0.8mm.

Wherein the opening of this main body is provided with ring-type shoulder face along rim, and the inner face periphery of this top flat is to be pressed against on this ring-type shoulder face.

For further specifying structure of the present utility model and feature, below lift some preferred embodiments now and cooperate graphic being described in more detail in after, wherein:

Fig. 1 is the structural representation of the utility model one preferred embodiment;

Fig. 2 is an A enlarged drawing partly among Fig. 1;

Fig. 3 is to show the same position structure of another preferred embodiment of the utility model under greenware condition corresponding to Fig. 2; And

Fig. 4 is to show the same position structure of the another preferred embodiment of the utility model under greenware condition corresponding to Fig. 2.

Please consult Fig. 1 earlier, it is the side sectional view of the golf club head 10 of the utility model one preferred embodiment, these bar head 10 inner hollow, profile is as good as with general club head, be to form by a

main body

20 and 30 seam of a top flat, wherein this main body 20 is to make with casting, be shelly, profile slightly is the club head shape, face 21 with club head, bottom 22, back 23, toe, position such as heel and neck (back three is not shown in the figures), and its position corresponding to bar crown portion (crown) forms an opening 24, and establishes ring-type shoulder face 25 along these opening 24 rims; 30 of this top flats are made with forging method in addition, be outer rim to knee-piece shape that should opening 24 rims, its thickness is for thin than this shelly main body 20, be below 1.0mm, (to annotate :) with the thinnest 0.7-0.8mm of accomplishing of present technology, and can accurate control the only about 1g of error with these top flat 30 weight that forging forms; Seeing also Fig. 2 is the enlarged drawing of top flat 30 and main body 20 joints, this top flat 30 is the openings 24 that are covered on this main body 20, top flat 30 inner face peripheries are pressed against on this ring-type shoulder face 25 that (annotate: shoulder face 25 has the function of top flat 30 chimeric storings before the convenient welding, but non-imperative), and 20 of top flat 30 and main bodys are fixed in addition with solder technology, aforementioned solder technology comprises by the bar head surface and freezes with welding rod along ring-type seam shop, or presets scolder in the composition surface of the two and give hard solder method of heating or the like again.

By this, this club head 10 is comparatively frivolous because of the top side part, the bottom side is partly comparatively thick and heavy, and presents the counter weight construction of centre of gravity, and preferable batting performance can be arranged.

At last, about the welding manner in the utility model processing procedure, be aided with that welding rod freezes or with scolder hard solder except aforementioned, as also can be as shown in Figure 3, establish a collar flange 26 prior to main body 20 ' surface along opening 24 ' rim in advance, top flat 30 ' embeds the back and burns a circle along these flange 26 welderings, the weldering of mat knot main body 20 ' and top flat 30 ' with the hot melt and dissolved flange 26 of height; As perhaps can be as shown in Figure 4, in advance prior to top flat 30 " outer rim establishes a continuous formed loop hook edge 31 of turnover; make top flat 30 " be covered on main body 20 " opening 24 " after, this hook edge 31 has contact with in opening 24 " on the rim, along 31 welderings of hook edge burn a circle make it melt and dissolved also can be with top flat 30 " and main body 20 " welded knot; Attrition process is trimmed again afterwards, makes the bar head surface smooth smooth.
