Description

Method for manufacturing multi-piece golf club head

The present invention relates to a method for manufacturing a golf club head, and more particularly to a method for manufacturing a golf club head of a wood type.

In existing golf clubs, such as driver woods, fairway woods, and general woods, the head of a wood club is relatively large in order to achieve the performance of hitting the ball from a long distance. In order to increase the freedom of design of the center of gravity of the club head and the moment of inertia (MOI) when hitting the ball, some wood clubs use lightweight materials or thin parts to reduce the weight of the club head, and transfer the reduced weight to other parts of the club head, thereby changing the center of gravity of the club head and the moment of inertia when swinging.

In the aforementioned wood-type club head, the weight of the club head body can be reduced by selecting materials, and transferred to other parts of the club head as a counterweight to improve the hitting performance of the club head, and the manufacturing of the club head with multiple parts is convenient for the manufacturing of wood-type club heads. However, the club head body of the existing wood-type club head is a hollow structure. When the club head hits the ball, the stress is directly transmitted from the hitting panel that hits the golf ball through the peripheral wall of the club head body to the tail end of the club head body, and it is impossible to generate a rebound performance that assists the forward movement of the hitting ball. Therefore, in terms of the manufacturing technology of the club head, how to manufacture a wood-type club head with excellent rebound performance is a key project in the current research and development of wood-type club heads.

The purpose of the present invention is to provide a method for manufacturing a multi-piece golf club head, so as to solve the technical problem that the golf club head manufactured by the existing golf club head manufacturing method is difficult to achieve better ball hitting rebound performance.

The invention of the multi-piece golf club head manufacturing method has at least the following technical features: 1. Constructing a club head that is easy to manufacture precisely: The invention uses a technical means of pre-forming multiple parts and then fixing them together to form a club head body embryo, so that the club body can be properly planned into multiple parts that are easier to mold, so that each part can be precisely controlled in shape and size, and then fixed together to ensure that the three-dimensional shape of the club head can meet aerodynamics, reduce subsequent surface processing, and accurately control the weight of the club head body, so as to facilitate the overall weight setting of the club head. 2. A structure that can improve the rebound performance of the ball during the manufacturing process: As mentioned above, the present invention can make the club body into multiple parts that are easier to mold through proper shape planning, and form an intermediate piece in the middle part of the club head. After the multiple club head parts are fixedly connected to form the club head body embryo, the intermediate piece is located inside the club head body embryo and faces the back of the hitting panel. In this way, the rebound performance of the club head when hitting the ball is improved through the structure of the intermediate piece inside the club head body.
