Abstract

A golf club head comprises a main body, and a striking plate. The main body is provided with an opening which is extended to form a first stepped portion and a second stepped portion. A groove is defined between the first stepped portion and the second stepped portion. On the one hand, the first stepped portion can support a striking plate by a smaller surface area to relatively increase a striking area of the striking plate to allow elastic deformation for striking. On the other hand, when the striking plate is combined with the main body by welding, the groove of the main body can obstruct an overflow melting metal from a welding portion between the main body and the striking plate so as to increase welding quality and avoid to affect elastic deformation of the striking plate.

Description

The invention relates to the structure of a golf club head, in particular to a groove extending at the opening step portion of the club head. When welding and combining the hitting panel, the groove can receive a golf ball with excessively infiltrated molten iron. Club head structure. [Prior art] The structure of a conventional golf club head, such as the US Patent No. 20002/01151551, please refer to FIG. 1 and FIG. 2, which includes a club body 101 and a Hitting panel 20. The head body 10 is a wood-type club head, which is provided with an opening Π and a stepped portion 丨 2, and the stepped portion 丨 2 is formed at the opening 丨 丨 inner edge 'which is used to support the shot The lip of the lower surface of the panel 20 is used to weld and join the head body 10 and the hitting panel 20. Furthermore, as shown in FIG. 2, the periphery of the hitting panel 20 may be folded to form a ring wall 21. ^ When the head body 10 and the hitting face plate 20 are welded together, since the peripheral edge of the opening U (that is, the welding position) of the head body 10 has a two-dimensional or three-dimensional three-dimensional curvature change, a welding device is necessary Correspondingly set 2 or 3 dimensional welding positions. However, in the case of radon energy welding, the more complicated the welding path conversion is, the more difficult it is to accurately control the welding depth of the welding position. As a result, when high-energy welding is performed with a high heat input, although sufficient welding depth can be obtained, excess molten iron [molten metal] is easily infiltrated into the head body 10 during the welding process. The molten iron will solidify between the head body 10 and the back of the impact panel 20, which not only reduces the effective deformation area of the impact panel 20 when hitting the ball, resulting in a coefficient of elastic recovery ^ 〇efficient 〇f restituti〇 n, c0r] is reduced, which also makes the appearance of this head body 10 poor. In addition, the excess molten iron will form beads.

Description of the Invention (3) To avoid the welding noise caused by the vibration of the finished product of the club head, The invention has the effect of improving welding quality. A secondary object of the present invention is to provide a golf club head structure. The club head system extends through an opening to form a first stepped portion and a groove. The excess molten iron infiltrated during welding can be effectively received by the groove. Therefore, the first stepped portion only needs to form a relatively small contact area for supporting the hitting panel, so that the present invention has the effect of improving the long-distance hitting ability. Another object of the present invention is to provide a golf club head structure. The club head system extends through an opening to form a first stepped portion and a groove. The excess molten iron infiltrated during welding can be effectively received by the groove. It can prevent the molten iron from solidifying in an anti-hook angle, so that the present invention has the broad effect of improving the process yield. 4 The golf club head structure according to the present invention includes a head body and a hitting panel. The head body is provided with an opening extending to form a first stepped portion and a second stepped portion, and a groove is formed between the first and second stepped portions. The first stepped portion carries a hitting panel with a relatively small contact area to relatively increase the effective elastic deformation area of the hitting panel. During welding, the groove can receive the excess molten iron that has penetrated into the body of the head to avoid problems such as the generation of welding beads and the sloshing noise and poor elastic recovery coefficient of the head body.

Proper distance. The second step portion 13 guarantees θ. Please refer to FIG. 4 and FIG. 5, which reveals that the welding method of the present invention combines the head body 10 and the ball striking surface. , Lei Qi φ Y 0 without thinking. This time, the combination of the arc 101 or the electron beam welding of the peripheral edge 101 and the outer peripheral edge of the ball striking panel 20 is 200mm. At this time, a part of the molten iron 31 (melt) of the weld bead 30 penetrates through the first step portion 12 of the head body 10 and the ball 202 on the surface of the ball 20a surface. This head body 10. The inventor's invention can use the groove 4 to efficiently receive the molten iron 3 to prevent the molten iron 31 from falling into the head body 10 to form a bead. On the other hand, since the infiltrated molten iron 31 has been effectively connected by the groove 14, the first stepped portion 12 can relatively reduce the contact area enough to support the f-ball panel 20, and the second The stepped portion 13 is also not required to contact and support the lower surface of the ball striking panel 20. When the contact area between the first stepped part 2 and the hitting panel 20 is smaller, the effective elastic deformation area of the hitting panel 20 will be larger ', so the hitting distance of the finished product of the club head can be relatively extended. Furthermore, in the present invention, an appropriate amount of flux (soldering flux, not shown) may be pre-coated on the groove 14 to ensure that the infiltrated molten iron 3 j can be tightly fixed with the help of the flux. In the trench 14. Please refer to Figs. 6 and 7, which show the structure of a golf club head according to a second embodiment of the present invention.

Description of the invention (6) The plate 2 0 is integrally formed by bending and extending to form a ring wall 2 1 and the head body 10 0 The first stepped portion 12, the second stepped portion 13, and the groove 14 are provided corresponding to the bad wall 21. The groove 14 can also be used to receive excess molten iron infiltrated [as shown in FIG. 5]. On the other hand, in the second embodiment, in addition to reducing the contact area of the first stepped portion 12 and the hitting panel 20 to increase the effective elastic deformation area of the hitting panel 20, it also further uses The ring wall 21 extended by the hitting panel 20 further enlarges the effective elastic deformation area of the hitting panel 20 to increase the hitting distance of the finished product of the 4 club head to the maximum. Please refer to FIG. 8, which shows the structure of a golf club head according to a third embodiment of the present invention. Compared with the first and second embodiments, the head body 10 of the third embodiment is an iron-type head. The front side of the head body 10 is also provided with an opening 11 (also referred to as a cavity portion), a first stepped portion 12, a second / second stepped portion 13, and a groove 14. The opening U can be formed to be open or closed on the back of the head body 10. The batting panel 20 may be initially embedded in the opening n of the head body 10 to facilitate subsequent high-energy welding processes.
