Description

  The present invention relates to a golf club head, and more specifically, refers to a kind of golf iron club head having a relatively excellent hitting effect.

  Conventional golf iron club club heads are provided with one concave groove in the front part of the club head, one metal plate is provided in the concave groove, a hitting groove is provided on the metal plate, and one hitting ball plate Is formed. Under such a structure, there is no space that can bend behind the ball striking plate, and when hitting the ball, the flexibility of hitting the ball is relatively poor, the contact time with the ball is short, and the frictional force generated is small, especially When hitting in a bunker, it is not possible to produce a more effective spin shot technique, and such disadvantages are more apparent.

  In another type of conventional iron club club head, a reinforcing fiber resin is filled in a groove on the front of the club head, and one metal plate piece is embedded in the groove. A hitting groove is provided on the metal plate piece, and the metal plate piece forms a hitting ball plate. Under such a structure, the ball striking plate, when subjected to a high-speed impact, compresses the reinforced resin, has one bending space, has flexibility, and increases the contact time with the ball. The above-mentioned drawbacks of the club head structure can be improved. However, the hitting area is limited on the front of the embedded metal plate piece, and the effective hitting area on the front of the club head is relatively small. In addition, in the recessed groove embedded in the metal plate piece, a trace of one circular reinforcing fiber resin is clearly seen around the hitting metal surface in front of the club head, and there is a discrepancy in the overall appearance. This is a drawback of such conventional club heads.

  The main object of the present invention is to provide a kind of golf iron club club head, in which the ball striking surface can produce relatively good flexibility and receive effective support. .

  To achieve the above object, the golf iron club head of the present invention includes the following. One shell body has a golf iron club club head shape, one recess in the front recess, and one ring-shaped shoulder is formed on the surface around the recess. ing. One soft metal layer is provided in the groove. One thin striking face layer is provided on the front of the shell body and supported on the shoulder, and one striking face plate is formed on the front of the thin striking face layer. One soldering layer is provided on the back side of the thin ball striking surface layer, and solders the thin ball striking layer on the soft metal layer at the shell body shoulder.

In order to explain the structure and features of the present invention in detail, the following two comparatively preferred embodiments will be described below in combination with the drawings.
FIG. 1 is a schematic view showing a golf iron club head according to an embodiment of the present invention.

See FIG. 1 and FIG. A golf iron club club head provided by one relatively advantageous embodiment of the present invention includes:
One shell body 10 has the shape of a golf iron club head and is made of metal. The front surface is provided with one concave groove 11, and the shell body 10 has one ring-shaped shoulder 12 formed on the surface around the concave groove 11.

  One soft metal layer 20 is provided in the concave groove 11, the hardness of the soft metal layer 20 is HRC9 or less, and the thickness is between 0.5 mm and 3 mm. In the present embodiment, the soft metal layer 20 is a single copper metal plate piece, and is formed by being embedded in the concave groove 11.

  One soldering layer 30 is provided between the soft metal layer 20 and the bottom surface of the concave groove 11, and the soft metal layer 20 is soldered into the concave groove 11, and the thickness of the soldering layer 30 is It is between 0.02 mm and 0.06 mm. In the present embodiment, the thickness of the soldering layer 30 is 0.038 mm, and is formed by soldering by melting one piece of amorphous metal material sheet with a nickel-based hard soldering material. It is a nickel-based hard soldering material of American AMS Association Number 4777F, such as Association Number BNI-2.

  One thin ball striking surface layer 40 is provided on the front surface of the shell body 10 and supported on the ring-shaped shoulder portion 12. The thin ball striking surface layer 40 has a hardness of HRC 35 or more and a thickness of 1. Several hitting grooves 41 are provided in front of a thin hitting layer 40 which is 5 mm or less, and one hitting surface 42 is formed. In the present embodiment, the thin ball striking surface layer 40 is a single piece of wear-resistant metal and is made of a vibration-cancelling steel metal material.

  See FIGS. 2 and 3 for one soldering layer 50. On the back side of the thin ball striking layer 40, the thin ball striking layer 40 is soldered on the soft metal layer 20 at the ring-shaped shoulder 12, and the thickness of the solder layer 50 is 0.02 mm to 0 mm. 0.06 mm. In the present embodiment, the thickness of the soldering layer 50 is 0.038 mm, and the thickness of the soldering layer 30 between the soft metal layer 20 and the concave layer 11 is the same. It is a nickel-based hard soldering material of the American AMS Association No. 4777F, such as the American AWS Association No. BNI-2, formed by soldering one amorphous metal material thin plate piece with the nickel-based hard soldering material. .

  On the outer peripheral surface of the portion where the thin ball striking surface layer 40 and the ring-shaped shoulder portion 12 are connected, one more ring-shaped soldering layer 60 may be further soldered, as shown in FIGS. As a result, the connection between the thin ball striking surface layer 40 and the shell body 10 is more strongly fixed. In this embodiment, the ring-shaped soldering layer 60 is formed by using TIG soldering.

  Therefore, the iron club club head according to the present embodiment has a relatively high structural strength with one soft metal layer provided on the back surface of one high hardness and wear resistant hitting ball surface, When the surface receives a high-speed impact force, the thin striking surface layer presses the soft metal layer backwards to create a flexing action, giving the striking surface a relatively excellent flexibility and a relatively superior hitting effect Have. In addition, since the entire thin ball striking surface layer covers the front front portion of the club head shell body, the ball striking surface has a larger effective ball striking area. .

  It is important to note that the soft metal layer of the present invention is soldered in the shell body connection using a single soldering layer as described in the above embodiment, and also uses a machined manufacturing method. And may be fixed directly in the connection of the soft metal layer, which also achieves the object of the present invention. Therefore, a structure in which the thin ball striking surface layer and the soft metal layer which are disclosed in the present invention are folded to form the front of the club head is also included in the scope of the present invention.
