Problems solved by technology

Since golf wood club heads have very specific shapes, the golf wood club heads are difficult to be formed as one piece.
However, during the acidic etching process to reduce the weight of the titanium alloy top crown of the conventional golf club head, it takes time and efforts to adhere the tapes on the portions of the top crown that do not need acidic etching.
Moreover, the shape of the titanium alloy top crown of the conventional golf club head is limited and can only be molded with slight changes.
The shape of the top crown cannot be molded accord

Embodiment Construction

[0030]With reference to FIG. 1, a manufacturing method of a top crown of a golf club head in accordance with the present invention comprises the following steps.

[0031]A titanium alloy panel is provided. Preferably, a thickness of the titanium alloy panel is 0.8 millimeter (mm) to 2.0 mm.

[0032]A forging mold is provided and is mounted in a forging processing machine. The forging mold has a mold cavity for forming the top crown of the golf club head. Preferably, the forging mold is made of an iron based alloy containing cobalt (Co) element, such that the forging mold can resist high temperature and impact, and has good ductility. Preferably, the forging mold is preheated before hot forging. The forging mold is preheated to a temperature ranging from 500° C. to 980° C. Within the temperature range, the ductility of the forging mold made of an iron based alloy containing Co element is increased. Accordingly, the forging mold is not broken easily during the hot forging process.

Abstract

A manufacturing method of a top crown of a golf club head has steps of: providing a titanium alloy panel, providing a forging mold, and mounting the forging mold in a forging processing machine, heating the titanium alloy panel, driving the forging mold by the forging processing machine to hot forge the heated titanium alloy panel to form the top crown, and forming multiple reinforcing ribs on at least one of a bottom surface and a top surface of a crown body of the top crown. Thus, the top crown with different thickness due to concave and convex surfaces thereon can be formed directly. Shapes and sizes of the top crowns can be determined precisely, such that qualities of the top crown are stable. The method for manufacturing the top crown is pollution-free, can be operated easily, is environment friendly, and has high production efficiency.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to a manufacturing method of a golf club head, especially to a manufacturing method of a top crown of a golf club head.[0003]2. Description of the Prior Art(s)[0004]Since golf wood club heads have very specific shapes, the golf wood club heads are difficult to be formed as one piece. Therefore, the conventional golf wood club head is usually manufactured by attaching four pieces, i.e. a top crown, a base, a strike face, and a hosel. For the top crown made of titanium alloy, multiple cavities are formed on an inner surface of the top crown by acidic etching to reduce weight and enhance elasticity of the conventional golf club head. Thus, the top crown of the conventional golf club head, which has an average thickness of 1 millimeter (mm), has some portions with thickness of 0.5 mm to 0.9 mm.[0005]When the cavities on the titanium alloy top crown are formed by acidic etching, tapes should be ...
