Benefits of technology

[0009]The primary objective of the present invention is to provide a technique for making a golf club head, wherein in the condition of the same bonding sizes, the strength of a main body and a hitting face after being bonded can be improved by more than 40%, thus reducing the coats, improving the efficiency, simplifying the technique and improving the hitting performance.
[0021]By using adhesive to bond the main body and the hitting face, the difficulty is reduced greatly, and the adhesive is easy to be acquired and it can achieve bonding under low temperature in the condition of the same bonding sizes, the strength of the main body and the hitting face after being bonded can be improved by more than 40% at a reduced cost and the production efficiency can be improved, and the manufacturing process can be simplified, Furthermore the performance of the golf club can also be improved.

Problems solved by technology

Pressing is used to deform the golf club through extruding, which is only suitable for the iron golf club, and the structure formed by pressing is unvaried.
However, this kind of process has the following disadvantages, thus restricting the mass production of the golf club: (1) Special braze welding equipment is required; (2) The braze welding material is difficult to acquire; (3) The manufacturing process is complex.
The technique is very complex.
Since the hitting face is the force-bearing part, the bonding strength of the body and the hitting face must be very strong, and the present bonding technique is unable to reach the requirement.

embodiment 1

[0033]The steps of Embodiment 1 are as following:

[0034]First, precisely molding a main body 1 with 17-4 stainless steel and a hitting face 2 with 6-4 Ti, the bonding surfaces of the main body 1 and the hitting face 2 being formed with a protruded section respectively that are relative to each other so as to form an L-shaped head, and the concave section engaging with the protruded section exactly (as shown in FIG. 1a);

[0035]Second, CNC processing cooperating with gap arithmetical ratio controlling +0.1 mm / −0 mm;

[0036]Third, surface treating by spraying each bonding face with AL2O3 so as to form micro concave and protruded portions, and the height of protruded portion being <0.3 mm;

[0037]Fourth, smearing the adhesive, whose shear strength is ≧25 Mpa, on the concave and protruded sections of the main body 1 and the hitting face 2, and then engaging the main body 1 with the hitting face 2 through the concave and protruded section;

[0038]Fifth, solidifying the adhesive through heating in...

embodiment 2

[0039]The steps of Embodiment 2 is as following:

[0040]First, precisely molding a main body 1, whose head is formed with a concave-shaped bonding surface, with 6-4TI, and forging a hitting face 2, whose head formed with a protruded-shaped bonding surface, with 6-4Ti; and the bonding surfaces engaging with each other exactly (as shown in FIG. 1d), the gap between the bonding surfaces being 1 of 6-4Ti being directly formed with micro concave and protruded portions, whose height is <0.3 mm, when being precisely molded;

[0041]Second, spraying the hitting face 2 of 6-4Ti with steel balls so as to form micro concave and protruded portions whose height is <0.3 mm;

[0042]Third, smearing the adhesive, whose shear strength is ≧25 Mpa, on the concave and protruded sections of the main body 1 and the hitting face 2, and then engaging the body 1 with the hitting face 2;

[0043]Fourth, solidifying the adhesive through heating in a oven for 40 minutes under the temperature of 140' C, thus the main body...

Abstract

A technique for making a golf club head comprises the following steps: (1) making a main body and a hitting face, both of which have a rough engaging bonding surface, separately; (2) bonding the main body to the hitting face through the engaging bonding surfaces with adhesive. The main body and the hitting face pf the present invention is bonded by adhesive, thereby the difficulty is reduced greatly, and the adhesive is easy to acquired and bonding can be achieved under low temperature, as well as the costs can be reduced, production efficiency can be improved and the manufacturing process is simplified. And the hitting performance of the golf club is also improved.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to a golf club head, and more particularly to a technique for making the golf club head.[0003]2. Description of the Prior Art[0004]When playing golf, the golf ball will fly toward the hole after being hit by the golf club head. In addition to the influence of the golf club, the rebounding coefficient i.e. COR will also influence the hitting performance.[0005]The metals used to make golf club head include: zinc alloy copper alloy, aluminum alloy, magnesium alloy, iron alloy, titanium alloy and compound materials, the hardness and the function of those metals are different, and different designs can obtain different hitting effects.[0006]At present, the golf club head is mainly made by pressing and braze welding. Pressing is used to deform the golf club through extruding, which is only suitable for the iron golf club, and the structure formed by pressing is unvaried. Braze welding is used to ...
