Abstract

A titanium alloy golf club head and a method for manufacturing the same are provided. The golf club head comprises a head base, a hitting face at a front edge of the head base and a top lid on the top of the head base. The head base, the hitting face and the top lid are connected to each other to form an entirety. The top lid has an inside surface comprising a plurality of recesses. With the recesses, the weight of the head is reduced while the volume of the head is increased. Meanwhile, the thickness of walls of the head base and of the hitting face does not need to be reduced. Since the weight of the top lid is reduced, the center of gravity of the head is lowered. A rib is formed between two adjacent recesses in the inside surface of the top lid so that an impact force on the head can be efficiently dispersed and the strength of the head is improved.

Claims

1. A titanium alloy golf club head, comprising:

a head base;

a hitting face at a front edge of the head base; and

a top lid on the top of the head base,

wherein the head base, the hitting face and the top lid are connected to each other to form an entirety, and the top lid has an inside surface with a plurality of recesses shaped by means of a forging process, and ribs are formed between two adjacent recesses and integrated with the top lid.

2. The golf club head of claim 1, wherein the recesses are arranged bilateral-symmetrically, and the depth of each of the recesses is identical.

3. The golf club head of claim 1, wherein at least two of the plurality of recesses are arranged in a splayed form.

4. The golf club head of claim 2, wherein at least two of the plurality of recesses are arranged in a splayed form.

5. The golf club head of claim 1, wherein at least two of the plurality of recesses are arranged in a scattered sector-shaped form.

6. The golf club head of claim 2, wherein at least two of the plurality of recesses are arranged in a scattered sector-shaped form.

7. The golf club head of claim 1, wherein the ribs are arranged in the form of a Chinese character of .

8. The golf club head of claim 2, wherein the ribs are arranged in the form of a Chinese character of .

9. The golf club head of claim 1, wherein at least part of the ribs are arranged in the form of a rhombus.

10. The golf club head of claim 2, wherein at least part of the ribs are arranged in the form of a rhombus.

11. A method for manufacturing the golf club head of claim 1, wherein a process for manufacturing the top lid comprises:

cutting a titanium alloy blank to form a semi-finished top lid;

preheating the formed semi-finished top lid, and

forging the preheated semi-finished top lid with a mould to form alternate recesses and ribs on a surface of one side of the semi-finished top lid.
