Description

Technical Field

[0001] This invention relates to a method for manufacturing golf club heads, and more particularly to a method for manufacturing multi-piece golf club heads for wood club heads. Background Technology

[0002] In existing golf clubs, such as drivers, fairway woods, and regular woods, the clubheads are relatively large due to their performance requirement of hitting the ball over long distances. To increase the design flexibility of the clubhead's center of gravity and moment of inertia (MOI), some existing wood clubheads utilize lightweight materials or have thinner components to reduce the weight of the clubhead body. This weight is then transferred to other parts of the clubhead, thereby altering the clubhead's center of gravity and moment of inertia during the swing.

[0003] In the aforementioned wood clubheads, the choice of materials does indeed reduce the weight of the clubhead body, allowing it to be redistributed to other parts of the clubhead as counterweight, thereby improving the clubhead's hitting performance. Furthermore, the use of multi-component clubheads facilitates the manufacturing of wood-type clubheads. However, existing wood-type clubheads have a hollow structure. When the clubhead strikes the ball, the stress is transmitted directly from the impact facet of the golf ball through the peripheral wall of the clubhead body towards the butt end, failing to generate the rebound performance that aids in forward trajectory. Therefore, in terms of clubhead manufacturing technology, how to manufacture wood-type clubheads with excellent rebound performance is a key project in the current research and development of wood-type clubheads. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a multi-piece golf club head manufacturing method, which solves the technical problem that golf club heads manufactured by existing golf club head manufacturing methods are difficult to achieve good ball rebound performance.

[0005] The technical solution proposed in this invention is: to provide a method for manufacturing a multi-piece golf club head, comprising:

[0006] The step of providing preformed multi-part clubhead components includes providing a pre-molded clubhead front section component, a clubhead tail section component, and at least one clubhead middle section component, wherein the front section component forms a striking face at its front end, and an upwardly projecting club connector is formed on one side of the front section component, and an intermediate member is provided in one of the clubhead middle section components;

[0007] The step of fixing multiple clubhead components together to form a preliminary clubhead body blank involves sequentially assembling and fixing the clubhead front section component, the clubhead middle section component, and the clubhead rear section component to form a preliminary clubhead body blank in the shape of a wood clubhead. The middle section component is located inside the preliminary clubhead body blank, and one side of the middle section component faces the back of the striking face.

[0008] The step of applying a surface treatment to the initial blank of the club head body involves grinding and cleaning the surface of the initial blank of the club head body to form a finished club head body.

[0009] In the multi-piece golf club head manufacturing method described above, in the step of providing pre-formed multi-piece club head components, a club head front section component, a club head tail section component, and a club head middle section component are provided. In the step of fixing the multi-piece club head components to form a club head body blank, the front end and rear end of the club head middle section component are respectively fixed to the rear end of the club head front section component and the front end of the club head tail section component.

[0010] In the multi-piece golf club head manufacturing method described above, in the step of providing pre-formed multi-piece club head components, the club head middle section component forms a middle section ring, and the intermediate component is formed in the front end, middle, or rear end of the middle section ring; in the step of fixing the multi-piece club head components together to form a club head body blank, the front end and rear end of the middle section ring are respectively embedded and fixed to the rear end of the club head front section component and the front end of the club head tail section component.

[0011] In the multi-piece golf club head manufacturing method described above, in the step of providing pre-formed multi-piece club head components, the intermediate piece forms a full-surface plate, and the entire periphery of the intermediate piece is connected to the inner periphery of the middle section ring.

[0012] In the multi-piece golf club head manufacturing method described above, in the step of providing pre-formed multi-piece club head components, the entire periphery of the intermediate part is connected to the inner periphery of the middle ring portion, and at least one through hole in the front-to-back direction is formed in the intermediate part.

[0013] In the multi-piece golf club head manufacturing method described above, in the step of providing pre-formed multi-piece club head components, at least one recess is formed on the front and / or rear sides of the intermediate component.

[0014] In the multi-piece golf club head manufacturing method described above, in the step of providing pre-formed multi-piece club head components, the club head front section component, the club head tail section component, and the club head middle section component are all made of carbon fiber material through molding and hot pressing.

[0015] In the multi-piece golf club head manufacturing method described above, in the step of providing pre-formed multi-piece club head components, the club head front section component and the club head tail section component are formed by hot pressing molding of carbon fiber material, and the club head middle section component is formed by molding of metal material.

[0016] The beneficial effects that can be achieved by this invention are at least as follows:

[0017] 1. Constructing a clubhead that is easy to manufacture with precision: This invention utilizes a technique of pre-forming multiple components and then fixing them together to form a clubhead body blank. This allows the clubhead body to be designed into multiple components that are easier to mold, and each component can be precisely controlled in terms of shape and size. After being fixed together, the three-dimensional shape of the clubhead can be made to conform to aerodynamics, reducing subsequent surface processing and allowing for precise control of the weight of the clubhead body, which is beneficial for the overall weight distribution of the clubhead.

[0018] 2. A structure that enhances ball bounce performance can be formed during the manufacturing process: As mentioned above, the present invention enables the club body to be designed into multiple parts that are easier to mold through proper body shape planning, and to form an intermediate part in the middle section of the clubhead. After the multiple clubhead parts are fixed together to form the clubhead body blank, the intermediate part is located inside the clubhead body blank and faces the back of the hitting panel. In this way, the structure of the intermediate part inside the clubhead body improves the ball bounce performance of the clubhead. Attached Figure Description

[0031] The following description, in conjunction with the accompanying drawings and embodiments of the present invention, further illustrates the technical means employed by the present invention to achieve its intended purpose.

[0032] This invention relates to a method for manufacturing multi-piece golf club heads, specifically a method for manufacturing club heads of a wood club head type. For example... Figure 1 and Figure 2 As shown, the specific implementation steps are as follows:

[0033] The step of providing preformed multi-part clubhead components includes providing a pre-molded clubhead front section component 11, a clubhead tail section component 12, and at least one clubhead middle section component 13. The front section component 11 forms a striking face 111 at its front end, and forms an upwardly protruding club connector 112 on one side of the front section component 11. The clubhead middle section component 13 has an intermediate member 132.

[0034] The step of fixing multiple clubhead components together to form a clubhead body blank 10 involves sequentially assembling and fixing the clubhead front section component 11, the clubhead middle section component 13, and the clubhead rear section component 12 to form a wood clubhead shape clubhead body blank 10. The middle component 132 is located inside the clubhead body blank 10, and one side of the middle component 132 faces the back of the hitting panel 111; and

[0035] The step of applying a surface treatment to the club head body blank 10 involves grinding and cleaning the surface of the club head body blank 10 to form a finished club head body.

[0036] In the step of providing pre-formed multiple clubhead components, the clubhead front section component 11, the clubhead tail section component 12, and the clubhead middle section component 13 are all made of metal materials and molded by casting or forging. The metal materials can be stainless steel, titanium, titanium alloy, aluminum, aluminum alloy, or other metal materials; or, the clubhead front section component 11, the clubhead tail section component 12, and the clubhead middle section component 13 are all made of carbon fiber materials and hot-pressed by molds; or, some of the components, such as the clubhead front section component 11, the clubhead tail section component 12, and the clubhead middle section component 13, are made of metal materials and formed by casting or forging, while the remaining components are made of carbon fiber materials and hot-pressed by molds.

[0037] In this embodiment, the clubhead blank 10 is configured as an assembly of three components: a clubhead front section component 11, a clubhead rear section component 12, and a clubhead middle section component 13. The clubhead front section component 11 and the clubhead rear section component 12 are made of carbon fiber and formed by hot pressing using a mold. The clubhead middle section component 13 is made of metal by casting or forging, or is made of carbon fiber and formed by hot pressing using a mold. Preferably, the clubhead middle section component 13 is made of carbon fiber and formed by hot pressing. By using carbon fiber, the weight of the finished clubhead is reduced, increasing the weight distribution margin of the clubhead and contributing to the weight distribution design of the golf clubhead.

[0038] In the aforementioned step of providing pre-formed multiple club head components, the front section component 11 of the club head is a hollow body with an opening facing rearward, the rear section component 12 of the club head is a hollow body with an opening facing forward, and the middle section component 13 of the club head has a middle section ring 131 and an intermediate member 132 integrally formed in the middle section ring 131. The intermediate member 132 can be provided at the front end, rear end, or middle section of the middle section ring 131, and the middle section component 13 of the club head has an opening at only one end, either at the front or rear end. Alternatively, the clubhead mid-section component 13 may have an open shape at both its front and rear ends, which facilitates the formation of an intermediate component 132 within the clubhead mid-section component 13. In the subsequent step of fixing multiple clubhead components together to form the clubhead body blank 10, the clubhead mid-section component 13 can be fixed to the rear end of the clubhead front section component 11 and the front end of the clubhead tail section component 12 respectively through the front and rear ends of the mid-section ring portion 131, so that the intermediate component 132 is located in the middle section of the clubhead body blank 10. In this embodiment, the front end and rear end of the mid-section ring portion 131 of the clubhead mid-section component 13 can be embedded into the rear end of the clubhead front section component 11 and the front end of the clubhead section component, respectively, and fixed together, so that the clubhead front section component 11, the clubhead tail section component 12, and the clubhead mid-section component 13 can be stably combined into one unit.

[0039] In the aforementioned step of providing pre-formed multiple clubhead components, the clubhead midsection component 13 can connect the entire periphery of the intermediate member 132 with the inner periphery of the midsection ring 131. The intermediate member 132 can be the entire surface of the blade; or, at least one through-hole can be formed in the intermediate member 132 along the front-rear direction; or, at least one non-through-hole can be formed on either or both of the front and rear sides of the intermediate member 132. The shape of the hole and the recess can be circular, polygonal, or other geometric shapes. The thickness of the intermediate member 132, as well as the size and location of the holes and recesses forming the intermediate member 132, can be adjusted and changed according to the actual product requirements, and can appropriately reduce the weight of the intermediate member 132 in the clubhead midsection component 13 by means of the holes or recesses while maintaining the necessary ball bounce performance.

[0040] In the step of fixing multiple club head components together to form the club head body blank 10, the club head front section component 11, the club head tail section component 12 and the club head middle section component 13 are fixed together by welding or adhesive bonding according to the materials.

[0041] The club head body manufactured by the aforementioned manufacturing method is then connected to the club connection part 112 to assemble a club connection assembly. A counterweight assembly is installed at the bottom or end of the club head body, and the club members are connected by the club connection assembly, thus constituting a golf club product.

[0042] When a user strikes a ball with a club head containing a middle member 132, the impact stress is transmitted from the periphery of the impact member 111 along the peripheral wall of the club head body when the club head's striking face 111 strikes the golf ball. When the stress is transmitted to the middle ring 131 of the club head's middle section component 13, part of the stress is directly transmitted to the club head's tail section component 12 through the club head's middle section component 13. The remaining stress is caused by the structure of the middle ring 131 of the club head's middle section component 13, which connects to the middle member 132, resulting in a rebound effect at the club head's middle section component 13 containing the middle member 132. This rebound force is transmitted forward to the striking face 111, thereby improving the club head's rebound performance when striking the ball and making the golf ball fly farther after being struck by the club head.

[0043] The above description is merely an embodiment of the present invention and is not intended to limit the present invention in any way. Although the present invention has been disclosed above by way of embodiment, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the technical solution of the present invention. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention shall still fall within the scope of the technical solution of the present invention.
