Background technique

Golf is popular all over the world, and has gradually become a popular sport at present. Due to the popularity of golf, not only professional golf players, but even amateur players who generally regard golf as leisure activities have the same requirements for golf equipment. Higher and higher, especially for the function and texture of golf clubs, there are higher expectations.

Therefore, club head manufacturers are all researching and developing according to the needs of users, especially the ball hitting panel that collides with the ball, of course, has also become the research and development object of the manufacturer. The general ball hitting panel needs to be able to directly collide with the ball. Bear the action force and rebound force generated between the moment of hitting the ball and the ball, so that the batter can easily grasp the direction and distance of the ball's flight. However, the general hitting panel is usually made of a metal plate including an alloy plate. When hitting When the panel collides with the sphere, the vibration generated will be transmitted to the batter's hand, making the batterer feel uncomfortable. In view of this, many companies continue to carry out research and development and design in order to improve the above shortcomings, such as the Taiwan patent announcement No. 550106 "Joint Method of Golf Club Head" and Taiwan Patent Publication No. M315595 "Joint Structure of Golf Club Head". : alloy stainless steel plate, titanium alloy plate, to achieve its preset effect, but the first plate and the second plate of the two different materials are mainly bonded by explosive welding to form a batting panel, and then The hitting face plate is welded and fixed in the vacuum welding box and the golf club head body by brazing to complete the finished club head; the aforementioned brazing and fixing method, in addition to high joint cost and poor mass production, is not suitable for golf club heads. When the batting panel collides with the ball for a long time, the batting panel is deformed due to the effect of stress, and then the two different plates are easily separated and loosened from the joint due to deformation, so that the golf club head Therefore, the service life is shortened, so there is a need for further improvement.

B. Simultaneously use the two different injection materials with a special double-mold and twin-screw injection molding machine to complete a double-layer alloy raw material with a hard alloy layer and a soft alloy layer;

C. Forming a double-layer batting faceplate by sintering and degumming at a high temperature of 1100°C to 1400°C for the double-layer alloy raw material of the hard alloy layer and the soft alloy layer;

D. Joining the ball striking panel with the golf club head body and performing the next step of processing.

In addition, the present invention also provides a ball striking faceplate of a golf club head with a double-layer powder metallurgy structure, which is a hard alloy layer formed by a stronger alloy powder and a soft alloy layer formed by a weaker alloy metal powder. Hitting panels with a double-layer structure formed of high-quality alloy layers.

After implementing above-mentioned technical means, the concrete effect that the present invention can reach is:

1. When the batting panel is joined to the ball head body, it can be welded in a low-cost, mass-producible welding method.

2. When the batting panel collides with the ball, the hard alloy layer can provide the strength and rebound force that the batting panel should have when hitting the ball, increasing the flying distance of the ball, while the soft alloy layer can absorb the impact when hitting the ball. The vibration energy generated can reduce the discomfort of the striker, and improve the practicality and durability of the swing.

3. When the hitting panel collides with the ball for a long time, the cemented carbide layer and the soft alloy layer have been combined into one through the burning process during manufacturing and molding, so they will not be separated and loosened, and the golf club can be extended life of the head.
