  • DETAILED DESCRIPTION OF THE INVENTION
  • FIG. 2 is a disassembled structure diagram illustrating a golf club head in accordance with one embodiment of present invention. In the present embodiment, the wood-type golf club head 20 for example, includes a head body 22 and a cup face 24. An opening 221 is formed on the front part of the head body 22 and a connection portion 222 is around the opening 221 to correspond to the cup face 24, wherein the common material of the head body 22 is stainless steel, such as 17-4 PH stainless steel. Further, a handle 26 is protruded form the side of the head body 22 to combine with a shaft (not shown). The cup face 24 includes a main board 241 having a bending portion 242 toward the head body 22 on at least one edge of the main board 241. In a C-type cup face, for example, the bending portion 242 is C-shaped and formed on three edges of the main board 241, and a joint surface 243 is formed on the front edge of the bending portion 242 to be combined with the connection portion 222 of the head body 22. Referring to FIG. 2 and FIG. 3, the main board 241 has an outer surface 244 as a striking face and an inner surface 245 toward the head body 22, and a board structure 246 is stacked on inner surface 245 by means of explosion welding to form an explosion welding layer (not shown) between the board structure 246 and the main board 241. In the present embodiment, the board structure 246 is a composite plate which is formed by stacking two different substrates, and the board structure 246, whose size is smaller than the size of the inner surface 245, is stacked on the center of the inner surface 245. Accordingly, in the present embodiment, the main board 241 is a steel substrate, and the board structure 246 is the combination of chemically pure titanium (CP Ti) substrate and titanium alloy (6-4Ti) substrate.
  • The manufacturing method of the cup face 24 includes: stacking the steel substrate, the pure titanium substrate and the titanium alloy substrate, performing an explosion welding process to combine the steel substrate, the pure titanium substrate with the titanium alloy substrate, and then milling the unnecessary portions of the pure titanium substrate and the titanium alloy substrate, and finally performing a press forging to manufacture the cup face, wherein the thickness of the steel substrate is about 0.5 to 4.0 millimeter (mm), the thickness of the titanium alloy substrate is about 0.5 to 4.0 mm, the thickness of the pure titanium substrate is about 0.5 to 2.0 mm, and the pure titanium substrate is between the steel substrate and the titanium alloy substrate.
  • In another embodiment, the board structure is only made of single substrate, such as pure titanium substrate, and the manufacturing method of the cup face includes: stacking the steel substrate and the pure titanium substrate, performing an explosion welding process to combine the steel substrate with a pure titanium substrate, and then performing the milling and the press forging processes to manufacture the cup face with two different substrates, wherein the thickness of the steel substrate is about 0.5 to 4.0 millimeter (mm), and the thickness of the pure titanium substrate is about 0.5 to 2.0 mm.
  • The foregoing design of setting board structure on the inner surface of the main board will improve the striking feeling. In the foregoing embodiment, the materials of the substrates of the cup face are not limited to steel, pure titanium and titanium alloy, and the stacking orders of foregoing different substrates are not limited, and further the substrates can be selected from two materials or over two materials of steel, titanium, copper, aluminum and magnesium. Besides, the combination of the joint surface and the connection portion is not only by welding, but also the pasting and the inserting.
  • FIG. 4 is a cross-sectional diagram illustrating a golf club head in accordance with another embodiment of present invention. The golf club head 20 includes a head body 22 and a cup face 24. An opening 221 is formed on the front part of the head body 22 and a connection portion 222 is around the opening 221. The cup face 24 includes a main board 241 with an outer surface 244 and an inner surface 245 having a bending portion 242 toward the head body 22 on the edges of the main board 241, and a joint surface 243 is formed on the front edge of the bending portion 242 to be combined with the connection portion 222 of the head body 22. The difference between this embodiment and the foregoing embodiment is that the board structure 246 in this embodiment covers on the outer surface 244 of the main board 241 to be as a striking face, wherein the board structure 246 is a composite plate which is formed by stacking two different substrates. In another embodiment, the board structure is only made of single substrate and covers on the outer surface of the main board.
  • In the foregoing design of covering board structure 246 on the outer surface 244 of the main board 241, the main board 241 is a steel substrate and the board structure 246 is a composite plate which is formed by stacking the pure titanium substrate and the titanium alloy substrate or a single substrate, such as a pure titanium substrate, to make the golf club head 20 with better elasticity and increase the striking distance. Furthermore, the mass center of the golf club head 20 can be adjusted because of the striking face made of titanium to satisfy the weight distribution that the weight of outside portion of the golf club head is lighter than the weight of inside portion of the golf club head. Besides, the materials of substrates of the cup face 24 are not limited to steel, pure titanium and titanium alloy, and the stacking orders of foregoing different substrates are not limited, and further the substrates can be selected from two or more materials of steel, titanium, copper, aluminum and magnesium.
  • Besides, FIG. 5 and FIG. 6 are two disassembled structure diagrams illustrating golf club heads in accordance with two different embodiments of present invention. Please referring to FIG. 5, the cup face 24 is an U-type cup face, wherein the bending portion 242 is formed on two opposite edges of the main board 241, and a joint surface 243 is formed on the front edge of the bending portion 242 to be welded with the connection portion 222 of the head body 22. Please referring to FIG. 6, the cup face 24 is an L-type cup face, wherein the bending portion 242 is formed on top edge of the main board 241, and a joint surface 243 is formed on the front edge of the bending portion 242 to be welded with the connection portion 222 of the head body 22.
  • Furthermore, in another embodiment, the iron-type golf club head 20 for example, as shown in FIG. 7, includes a head body 22 and a cup face 24. An opening 221 is formed on the front part of the head body 22 and a connection portion 222 is around the opening 221. The cup face 24 includes a main board 241 having a bending portion 242 toward the head body 22 on three edges of the main board 241, and a joint surface 243 is formed on the front edge of the bending portion 242 to be combined with the connection portion 222 of the head body 22. Please referring to FIG. 8, the main board 241 has an outer surface 244 and an opposite inner surface 245, and a board structure 246 is stacked on the inner surface 245 of the main board 241 by means of explosion welding, wherein the board structure 246 is a composite plate which is formed by stacking two different substrates. Further, in another embodiment, the board structure 246 as shown in FIG. 9 also can cover on the outer surface 244 of the main board 241.
  • To sum up, in the present invention, the explosion welding way is used to combine different substrates of cup face, to have high combination intensity between different substrates of cup face. Furthermore, when the cup face and the head body are welded, the welded areas are far away from the combination area of the main board with the board structure because of the design of the bending portion of the cup face, so that the high welding temperature will not destroy the combination intensity between the board structure and the main board or the combination intensity between different substrates of board structure. Therefore, the present invention can prevent the separation of different substrates and effectively enhance the quality of the golf club head. On the other hand, because the welded areas are far away from the striking area, the striking area can be expanded to enhance the striking function which was limited by the welded areas in the past.
  • Although the present invention has been explained in relation to its preferred embodiment, it is to be understood that other modifications and variation can be made without departing the spirit and scope of the invention as hereafter claimed.
