Description

[Detailed description of the device]

[0001]

[Technical field to which the device belongs]

 The present invention relates to a driver head for a golf club.

[0002]

[Prior art]

 Since the manufacturing process of golf club driver heads made from traditional forged aluminum alloy is complicated, and the products always have defects such as pinholes, etc., research on the manufacture of forged hollow driver heads for golf clubs. Contractors are putting a lot of effort into development.

[0003]

[Problems to be solved by the device]

 However, the forged product cannot create the driver head only once, but first forges two or three shells and then welds them together.So far, there are several different split structures. Is proposed. The main object of the present invention is to provide a forged aluminum alloy driver head for a golf club, in which most of the driver head is integrally formed by forging, and a better structure can be obtained.

Another object of the present invention is to provide a driver head for a forged aluminum alloy golf club which has no welding line on the bottom of the club head.

[0005]

[Means for Solving the Problems]

 To achieve the above object, the driver head for a golf club provided by the present invention includes the following. The main body is integrally molded of forged aluminum alloy, and has a face, bottom, back, toe, heel and neck, and a shaft hole provided in the center of the neck for shaft mounting. It has a hollow interior and an open top, with a shoulder extending from the top end of the face to the rear, on either side of the toe and neck side, respectively. It is welded to the side, and a groove is provided on the peripheral surface of its open end. The lid plate is fitted and welded into the groove at the open end of the main body, thereby closing the open end of the main body and forming the top surface of the club head together with the shoulder portion.

[0006]

[Embodiment of device]

 Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 shows a structure of a conventional club head 10, which is forged into a face plate 11 and a shell body 12, in which the shell body 12 is forged once or welded into two pieces and then welded. Alternatively, the face plate 11 may be welded to the open end of the shell body 12. When a ball is hit with such a club head, it is deformed due to elastic strain as shown in FIG. 2, and the welded portion 13 of the shell body 12 easily bursts. Further, FIG. 3 shows another structure of the club head 20, in which a shoulder portion 22 is extended backward in the peripheral edge of a face plate 21 of the club head 20, and the shell body 23 has a structure of one or more shoulder portions. Weld 22 and shell 23. When the ball is hit by the club head 20, the deformation due to the elastic strain generated in the surface portion 21 does not affect the welding location. Although the latter is structurally superior to the former, both of them affect the texture of the club head because the weld lines 14 and 24 are formed at the bottom of the head.

As shown in FIG. 4, the golf club driver head 30 of the present invention includes the following. The main body 40 is integrally formed of a forged aluminum alloy, and has a surface portion 41, a bottom portion 49, a back portion 42, a toe portion 43, a heel portion 44 and a neck portion 45, and a shaft (in the drawing, in the drawing) at the center of the neck portion 45. A shaft hole 46 for mounting (not shown) is provided, the inside of which is hollow, the top face is open, and the shoulder 47 is formed integrally with the top end of the face and is rearward. The shoulder 47 is welded to both sides 471 and 472 of the shoulder 47 at the upper end of the toe 47 and the side of the neck 45, respectively, and a groove 48 is provided on the peripheral surface of the open end thereof.

The lid plate 50 is welded to the groove 48 at the open end of the body 40, thereby closing the open end of the body and forming the top surface of the club head with the shoulder 47. The body 40 of the present invention is forged into a structure shown in FIG. 5 with an aluminum alloy, and the shoulder 47 is pressed so as to be curved. Since it contacts the concave grooves 431 and 451 on the side edges, they are connected by welding. The lid plate 50 can be manufactured by a method of forging, casting or die casting.

The head 30 of the present invention is almost integrally formed by forging, and only the open end on the rear side of the top surface of the main body 40 is welded to another cover plate 50. Therefore, the structure thereof is the same as that of the two examples described above. Better than anything. In addition, since there are no welding lines on the front and bottom surfaces of the head 30, electroplating can be performed, and the surface is extremely clean and no trace of welding lines remains. If the top surface, back surface, toes, heels and neck of the head are further painted, it is possible to completely remove the material after welding and the cover plate 50 does not receive the force at the time of hitting the ball, so that the vibration is not deformed. The present invention can obtain extremely good quality because there is no fear that the paint will peel off at the welded part due to the above.

The present invention has a double head structure in which the face, bottom, back, toe, heel, and neck are integrally molded, and the top is covered with a lid plate, and the main body 40 and the lid plate are covered. In order to move the welding points of 50 back and avoid the drawbacks shown in FIG. 2, a shoulder 47 of a predetermined height is integrally extended upward on the surface 41, and the shoulder 47 is moved backward. By bending so that it can be bent, and then welding both ends to the structure of the main body, such a head structure becomes a new structure that has never existed before, and has the advantage of a strong structure and good quality.
