[0002] At present, most of the golf club heads are joined by two or three pieces of metal components. The common type is like joining a ball hitting panel to the front side of a club head body, or joining together two or three pieces of shell-shaped components. A hollow club head, etc., in addition to the reasonable method of manufacturing and molding, the biggest advantage should be that different parts of the club head can have different physical properties (such as stronger body rigidity, better elasticity of the hitting panel, or heavier bottom and lighter top. etc.), based on this, the general golf club head is mostly made of different metal materials, and generally speaking, the joining method is almost all welding methods such as general welding or brazing (brazing), but the welding method is used to join When different metal components are used, due to the differences in the melting point, condensation rate, and crystal phase structure of the metals, the joint strength between the components is actually not high, and it will still be cracked and separated after multiple hits.

Embodiment Construction
[0018] Please refer to Figure 1 to Figure 4 , the joining method of the golf club head provided by the first preferred embodiment of the present invention is as follows:
[0019] Such as figure 1 As shown, a first main part (10), a second main part (20) and a frame ring part (30) are prefabricated by casting or forging, wherein the material of the first main part (10) is Stainless steel, the shape corresponds to the rear main part of the golf iron club head, a recess (11) is recessed from the center of the front to the back (note: depending on the design, there may be no recess or no penetration), and the front outer The edge has an annular groove (12), and the front and rear side walls (13) of the groove (12) are inclined slightly outward (about 3°); the material of the frame (30) is Titanium alloy, the shape corresponds to the annular groove (12) of the first main part (10), and the inner peripheral surface also presents a slope corresponding to the side wall (13) of the ...

The jointing method of golf club head includes the following steps: firstly, preparing a first main piece, a second main piece and a frame ring piece, in which the forms of first main piece and second main piece are mutually matched, and can be combined into a form a club head, and both are different in metal material quality, and the form of said frame ring is correspondent to said first main piece and matched with p eripheral contour profile of one side of said second main piece, and its material quality is identical to said second main piece; then heating said frame ring piece to make it slightly be expanded, promptly ring-covering the above-mentioned peripheral position, after it is cooled and contracted, fastening said first main piece and combining said frame ring and first main piece together.
Description
technical field [0001] The present invention is related to the manufacturing method of the golf club head, in particular to a method for joining metal components of different materials into a golf club head. Background technique [0002] At present, most of the golf club heads are joined by two or three pieces of metal components. The common type is like joining a ball hitting panel to the front side of a club head body, or joining together two or three pieces of shell-shaped components. A hollow club head, etc., in addition to the reasonable method of manufacturing and molding, the biggest advantage should be that different parts of the club head can have different physical properties (such as stronger body rigidity, better elasticity of the hitting panel, or heavier bottom and lighter top. etc.), based on this, the general golf club head is mostly made of different metal materials, and generally speaking, the joining method is almost all welding methods such as general wel...
