Problems solved by technology

Although the club head body 3 and the counterweight 4 are welded to improve the bonding strength between the two, however, due to high temperature welding, both the club head body 3 and the counterweight 4 are melted, and the molten pool is disturbed during welding. , Welding speed, current and heat input make the weld bead different in depth
Therefore, after the surfaces of the club head body 3 and the counterweight 4 are surface treated, irregular weld bead is left, which makes it difficult to manage the quality of the golf club head and affects the appearance.
Furthermore, if the club head body 3 is made of titanium or titanium alloy, due to the poor weldability between titanium and dissimilar metals, welding hot cracks often occur, such as "Titanium Welding" published by Quanhua Science and Technology Books Co., Ltd. Technology' pages 3-4, section 3.2.2 Titanium and other metal welding, joining states: Titanium and dissimilar metals look similar, but titanium and titanium will also embrittle the weld

Embodiment 2

[0039] Such as Picture 9 , Picture 10 As shown, the present invention includes a club head body 5 and a counterweight 6a.

[0040] The head body 5 is provided with an accommodation chamber 51 for accommodating the counterweight 6. It is made of S20C, 8620 or SUS304 material.

[0041]The weight 6a is provided with a convex portion 61 formed around and connected by an inclined surface 612, which is made of a high melting point material as shown in Table 1, such as tungsten (W), tantalum (Ta), molybdenum (Mo) or niobium (Nb). ), etc. It can also be made of other high melting point materials and a small amount of other metals as alloy materials. Since the melting point of the high melting point metal is too high to be melted by a general high-frequency melting furnace, the weight 6 is preferably manufactured by a powder metallurgy process.

[0042] The counterweight 6 a is accommodated in the chamber 51 of the club head body 5, and a channel is formed between the upper inclined surf...

Embodiment 3

[0044] Such as Picture 10 , Picture 11 As shown, the present invention includes a club head body 5a and a counterweight 6.

[0045] The head body 5a is provided with a chamber 51 for the counterweight 6 to be accommodated and a flange 52 formed on the periphery of the chamber 51, which is made of titanium or titanium alloy, such as 6-4 titanium, or low carbon. Made of steel, low-alloy steel or stainless steel. The flange 52 is integrally formed on the head body 5a to be directly used as solder during the welding process.

[0046] The weight 6 is provided with a convex portion 61 surrounded by a step portion 611, which is made of a high melting point material as shown in Table 1, such as tungsten (w), tantalum (Ta), molybdenum (MO) or niobium (Nb) It can also be made of other high melting point materials and selected a small amount of other metals as alloy materials. Since the melting point of the high melting point metal is too high to be melted by a general high-frequency meltin...

Abstract

Golf-club head preventing weighing block from melting in the process of welding is disclosed. The club head includes a club body main and a weighing block, the main body is equipped with a container for the weighing block whose melting point is higher than that of the main body, and a channel for melted welding materials forming after cooling solidification between the weighing block and the container.

Description

Technical field [0001] The invention belongs to parts of golf sports equipment, in particular to a golf club head with a weight that does not melt during the welding process. Background technique [0002] In order to obtain a better hitting effect with conventional golf club heads, materials with a better coefficient of rebound (COR) are usually selected to make the golf club head body so as to hit the ball farther under the same hitting force. In addition, the material with good shock absorption can absorb most of the shock after hitting the ball. If the hitter fails to hit the sweet zone of the hitting panel when hitting the ball, it can reduce the shock transmitted to the hitter's hand. Therefore, it is preferable to choose titanium or titanium alloy as the material of the head body. However, because the specific gravity of titanium is about 4.51, if only titanium or titanium as the main component of the material, such as 6-4 titanium as a golf club head, after the golf club h...
