Description

Technical Field

[0001] The present invention relates to a technology in the field of golf club manufacturing, in particular to a combination component of a golf club head, a combination process of the combination component and a finished product. Background Art

[0002] The golf club head is an important part of the golf club, especially the weight in the club head, which has a significant impact on the center of gravity distribution, hitting performance and the feel of the golfer. By adding weights to different parts of the club head, the center of gravity position of the club can be changed, affecting the flight trajectory and rolling characteristics of the ball, thus directly affecting the effect of hitting the ball.

[0003] The assembly process of the weight block and the club head body has a direct impact on the performance of the club head. The current processes have the following defects:

[0004] ① Threaded connection: The counterweight block and the club head body are fixed by screws. After repeated collisions between the club head and the golf ball, the screws loosen, causing the counterweight block to loosen or even fall off.

[0005] ② Welding: The weight block and the club head body are fixed by melting and cooling the solder; however, the weight block and the club head body are made of different materials, and the solder cannot completely fuse the two, which can easily cause cracks at the weld after hitting the ball;

[0006] ③ Gluing: The weight block is fixed to the club head body by adhesive; however, the durability of the adhesive is poor and it is easy to age under repeated impact, causing the weight block to loosen and fall off easily.

[0007] In addition, the first two assembly processes are prone to liquid seepage during corrosion resistance tests and subsequent electroplating treatments, which affects the product's appearance and aging resistance.

[0008] In order to solve the above problems in the prior art, the present invention is provided. Summary of the invention

[0009] In view of the above-mentioned deficiencies in the prior art, the present invention proposes a composite component of a golf club head, a bonding process of the composite component and a finished product, which does not require the assistance of dissimilar materials, and the club head body and the counterweight block are directly fixed, thereby improving the appearance quality, aging resistance and bonding reliability of the product.

[0010] A first aspect of the present invention relates to a composite component of a golf club head, comprising:

[0011] A counterweight block having a top boss and a bottom boss;

[0012] The club head body is provided with a counterweight groove for accommodating the counterweight, the counterweight groove comprising a first groove corresponding to the counterweight body and a second groove corresponding to the protrusion at the bottom of the counterweight; at the corresponding parts of the counterweight and the club head body, the depth of the counterweight groove is not less than the height of the counterweight; the club head body is provided with a circle of flanges along the edge of the counterweight groove, the flanges are used to fill the gap between the counterweight groove and the counterweight.

[0013] A second aspect of the present invention relates to a process for combining components of a golf club head, comprising the following steps:

[0014] The counterweight block is placed in the counterweight block groove of the club head body, and then the club head body is forged along the flange so that the remaining gap between the first groove and the second groove is completely filled, and finally the excess material is polished to remove the top surface of the club head body and the counterweight block so that the top surface of the club head body and the counterweight block is flat.

[0015] The third aspect of the present invention relates to a finished golf club head, comprising the above-mentioned counterweight block and the club head body, which is manufactured by the above-mentioned combining process; the flange fills the gap between the counterweight block groove and the counterweight block so that the counterweight block is embedded in the counterweight block groove to form an upper latch structure and a lower latch structure.

[0016] Compared with the prior art, the present invention has the following technical effects:

[0017] Along the depth direction of the counterweight groove, the counterweight forms a latching structure with the club head body at the top and bottom positions, which can be tightly combined without the assistance of dissimilar materials, thereby improving the product's appearance quality, aging resistance and combination reliability; and both the counterweight and the club head body can be precision forged, and only the flange part of the club head body needs to be forged, which greatly reduces the workload of forging and polishing and significantly improves manufacturing efficiency.

[0024] The present invention is described in detail below with reference to the accompanying drawings and specific implementation modes.

[0025] Example 1

[0026] like Figure 1 and Figure 5 As shown, in this embodiment, a finished product of a combined component of a golf club head is provided, including: a weight block 100 and a club head body 200 .

[0027] The finished product of the golf club head assembly is composed of Figure 2 and Figure 3 The weight block 110 and the club head body 210 are assembled and then forged and polished.

[0028] like Figure 2 and Figure 4 As shown, the counterweight 110 is provided with a top boss 111 and a bottom protrusion 112; the corresponding club head body 210 is provided with a counterweight groove for accommodating the counterweight, and the counterweight groove includes a first groove 211 corresponding to the counterweight body and a second groove 212 corresponding to the bottom protrusion of the counterweight; the club head body 210 is provided with a circle of flange 213 along the edge of the counterweight groove.

[0029] Preferably, the counterweight groove of this embodiment is provided with a square boss, one side of which abuts against the side wall of the counterweight groove, thereby dividing the counterweight groove along the groove depth direction into a first groove 211 and a second groove 212. Of course, other types of boss structures can be used according to design requirements, but it is necessary to ensure that the counterweight groove forms grooves with different cross-sectional shapes and / or widths in the groove depth direction to form upper and lower latch structures.

[0030] When manufacturing the finished product of the golf club head assembly component of this embodiment, the weight block 110 is placed in the weight block groove of the club head body 210, and then the club head body 210 is forged along the flange so that the remaining gap between the first groove and the second groove is completely filled to form an upper and lower latch structure, such as Figure 5 Finally, remove the excess material by grinding to make the top surface of the club head body and the weight block flat, and obtain the following Figure 1 Finished product shown.

[0031] It should be emphasized that the above are only preferred embodiments of the present invention and do not limit the present invention in any form. Any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
