Heterogeneous metal combined golf iron head manufacturing method

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.

Most of the early golf club heads were made by precision casting or forging of a single steel. Because their ball striking performance is limited by the material properties of a single material, it is often unable to meet the needs of users when hitting the ball. Therefore, in order to improve the hitting performance of the golf club head, the existing golf club head adopts a structure in which a heterogeneous metal is combined.

At present, a conventional method for manufacturing a golf iron head with a heterogeneous metal combination is shown in FIG. 6 and FIG. 7, which is formed by a casting method to form a head body rough blank 30, and a panel assembly is formed in the head body 30 The groove 31 is formed with a flange portion 32 at the periphery of the panel mounting groove 31. The other punching means pre-forms a ball striking panel 40. The peripheral edge of the ball striking panel 40 is formed with a ring groove 41, and the ball striking panel 40 is placed on the rod. In the panel mounting groove 31 of the head main body rough blank 30, the flange portion 32 at the periphery of the panel fitting groove 31 of the head main body 30 is bent laterally and extended to the periphery of the ball striking panel 40 by hydraulic pressure or pressing means. In the ring groove 41, the head body rough blank 30 is formed into a predetermined shape of the iron head body 30A and the ball striking panel 30 is fixed to form a golf iron head.

However, in the conventional golf iron head manufacturing method, the technical method of fixing the flange portion of the peripheral edge of the panel fitting groove of the iron head body to the ring groove of the periphery of the ball striking panel by hydraulic pressure or pressing is used. There is a gap between the iron head body and the hitting panel, which causes the joint strength between the iron head body and the hitting panel to be insufficient, so that after the golf iron head has repeatedly hit the ball, the hitting panel is prone to fall off, and at the same time, the iron head There is a gap between the body and the hitting panel, which causes the iron head to feel bad and has a bad sound.

The main purpose of the present invention is to provide a golf iron head manufacturing method, which solves the existing golf iron head manufacturing method, and has a gap between the iron head body and the hitting panel, and the joint strength between the iron head body and the hitting panel, The batting panel is easy to fall off, and the iron head has a bad hitting feeling and a problem of hitting the ball.

In order to achieve the foregoing, the golf iron head manufacturing method proposed by the present invention comprises the following steps: providing a pre-formed metal iron head body, the iron head body comprising a base and a side formed on one side of the base a rod connecting portion, the front side of the base forming a concave panel mounting groove, the base forming one or a plurality of concave recesses on the peripheral wall of the panel mounting groove; providing a pre-formed metal substrate panel, the panel The material of the substrate is different from the material of the iron head body. The shape of the panel substrate substantially corresponds to the panel mounting groove of the mast head body, and the thickness of the panel substrate is greater than the depth of the panel mounting groove; the panel substrate is placed on the iron rod The panel mounting groove on the front side of the head body, and the panel substrate protrudes from the front side of the iron head body; the combination of the panel substrate and the iron head body is preheated to the forging temperature, and the preheating forging temperature is 600 ° C to 1100 ° C; And forging the combination of the preheated panel substrate and the iron head body, so that the ball striking panel is extruded into the panel of the iron head body by extruding the flange at the periphery The corresponding recessed groove in the groove is integrally formed into a golf iron head. The combination of the preheated panel substrate and the iron head body is placed in the forging die, and the panel substrate is forged. The panel substrate is formed into a predetermined shape of the ball striking panel by forging and tightly integrated with the iron head body, wherein the ball striking panel extrudes the flange at the periphery thereof by forging and causes the flange to be embedded in the iron head body In the corresponding groove of the panel mounting groove, the front side of the ball striking panel is flush with the front side of the iron head body.

By the creation of the method for manufacturing the golf iron head, the main purpose is to form one or a plurality of concave recesses on the peripheral wall of the panel assembly groove by using the preformed iron head body, and the shape of the pre-formed panel substrate substantially corresponds to The panel mounting groove of the head body, the thickness of the panel substrate is greater than the depth of the panel mounting groove, so that the panel substrate is installed in the panel mounting groove of the iron head body, and the panel substrate protrudes from the front side of the iron head body, and then When the panel substrate is formed into a ball striking body by the forging means, the panel substrate protrudes from the iron body and has excess material, so that the panel substrate can be extruded under the forging action, and the periphery of the panel substrate can be extruded. The golf iron head is fixed by being fixed in the corresponding recessed groove in the panel fitting groove of the embedded iron head body. According to this, the hitting panel can be tightly combined with the iron head body without gaps to form an integrally formed golf iron head. The joint between the hitting panel of the forged golf iron head and the iron head body is not easily separated, and the bonding strength between the two is improved, and the hitting panel and the iron head body are tightly coupled without any gap, so that the iron head hits the ball. It has a better sense of hitting and no abnormality in hitting the ball.
