Abstract

Disclosed is a method for manufacturing an iron golf club head of a combination of heterogeneous metals, which is to provide an iron club head body and a heterogeneous face plate substrate that are formed in advance. The face plate substrate is put into a face plate combination slot of the iron club head body, and the face plate substrate protrudes out of a front surface of the iron club head body. The combination of the face plate substrate and the iron club head body is preheated and then, forging is applied for squeezing a rim of the ball-hitting face plate to have a flange embedded, through forging, into the embedding slot corresponding to the face plate assembly slot of the iron club head body, thereby fixed to form, in an integrated form, an iron golf club head. Furthermore, the ball-hitting face plate can be tightly combined with the iron club head body with no gap therebetween so that the ball-hitting face plate and the iron club head body do not easily detach from each other thereby providing the iron club head with better ball-hitting feeling without different phoneme of ball-hitting when the iron club head hits a ball.

Description

Manufacturing method of heterogeneous metal combined golf iron head

The invention relates to a method for manufacturing a golf iron head, in particular to a method for manufacturing a golf iron head with a heterogeneous metal combination.

Early golf club heads were mostly made of a single steel material through precision casting or forging. Because their hitting performance is limited by the material characteristics of a single material, they often cannot meet the needs of users when they hit the ball. Therefore, in order to improve the hitting performance of the golf club head, the existing golf club head adopts a structure of heterogeneous metal bonding.

At present, a conventional method for manufacturing a golf iron head combined with a heterogeneous metal is shown in FIG. 6 and FIG. 7. It uses a casting method to preform a rough head body 30 and a panel assembly is formed in the rough head body 30. Groove 31, and a flange portion 32 is formed on the periphery of the panel mounting groove 31, and a ball striking panel 40 is preformed by punching means. A ring groove 41 is formed on the periphery of the ball striking panel 40, and the ball striking panel 40 is placed on the rod In the panel mounting groove 31 of the head body rough embryo 30, the flange portion 32 at the periphery of the panel mounting groove 31 of the head body rough embryo 30 is bent laterally to extend to the periphery of the impact panel 40 by hydraulic or punching means. In the ring groove 41, the rough head body 30 is formed into a predetermined shape of the iron head body 30A and the hitting face plate 30 is fixed to form a golf iron head.

However, in the conventional golf iron head manufacturing method described above, because the flange portion of the peripheral edge of the panel mounting groove of the iron head body is laterally bent to a ring groove on the peripheral edge of the hitting panel by oil pressure or pressing, There is a gap between the iron head body and the hitting panel, resulting in insufficient bonding strength between the iron head body and the hitting panel, which makes the golf iron head prone to fall off after multiple shots. There is a gap between the body and the hitting panel, which causes the hitting feeling of the iron head to be bad and there is a strange sound of hitting.

The main purpose of this creation is to provide a golf iron head manufacturing method that solves the existing golf iron head manufacturing method, which will leave a gap between the iron head body and the hitting panel, and cause the bonding strength between the iron head body and the hitting panel, The hitting panel is easy to fall off, the hitting feeling of the iron head is not good, and abnormal hitting sounds are generated.
