Description of the Invention: [Technical Field] The present invention relates to a method for surface hardening of a golf club head, and more particularly to a surface hardening of a golf club head which uses light to heat a metal surface to achieve a heat treatment effect. Approach. [Prior Art] Due to the demand for the golf ball hitting function, it is often required that the hardness of some specific portions can be high-point, and the common practice is to apply a coating method to increase the surface hardness. For example, by using electroplating, physical vapor deposition, or chemical vapor deposition (CVD), a high hardness layer is coated on a portion to be reinforced, thereby achieving the purpose of improving hardness. However, the golf club head made in this way can be lifted only for the area that needs to be strengthened, but the golf head often has a large impact force due to the impact force after a period of use. The phenomenon of peeling off, not only affects the function of use, but also becomes quite unattractive. 除了 In addition to the above-mentioned addition method to increase the hardness, there is a way of using heat treatment to improve the hardness of the golf head. However, since this method requires the entire golf head to be placed in a heating furnace for high temperature treatment, only the overall hardness of the golf head can be simultaneously increased. The disadvantage of using this method is that it can only be applied to a golf head made of a single material, and it is completely unsuitable for a golf club that wants to absorb vibration and increase the feeling of hitting through a soft elastic region. It. In other words, although the heat treatment can increase the hardness of the golf club head, 5 1290842, the area to be lifted is comprehensive and uncontrollable, and cannot be partial. SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a method for hardening a golf club head surface which is capable of causing only a hardening effect on a metal surface of a partial region and the hardened region is controllable. Thus, the golf ball surface hardening treatment method of the present invention comprises a preparation step of preparing a golf ball head, and a beam irradiation step of placing the golf head into a protective gas-filled step. In the cavity, the golf ball head is irradiated with a beam generator that generates a high-energy beam, and the surface of the golf head is heated to achieve heat treatment and hardening. The invention has the effect of illuminating a partial surface of the golf head with a high-energy beam of the beam generator, and forming a protective surface and cooling effect with a protective gas to increase the hardness of the surface and can be moved by a high-energy beam. The path to control the size of its hardened area. The above and other technical contents, features, and advantages of the present invention will be apparent from the following detailed description of the preferred embodiments. As shown in Figs. 1 and 2, a preferred embodiment of the method for hardening a golf club head according to the present invention comprises a preparation step u and a beam irradiation step 12. In the preferred embodiment, the golf club head is subjected to a surface hardening treatment. However, in practice, the application to the surface of the article made of other metal is not intended to limit the scope of application of the present invention. 1290842 The remote preparation step 11 is to prepare a golf ball head 2 made of titanium alloy, but it can also be made of one of aluminum alloy, carbon steel or stainless steel. In the preferred embodiment, the golf club head 2 is a golf head that is an Iron Head. Of course, it can also be a golf club head head' or a golf head of a putter head. The beam irradiation step 12 is performed in a hardening processing apparatus 3 having a cavity 31, a gas delivery unit 32 into which a protective gas can be introduced into the cavity 31, and a cavity disposed in the cavity A stage 33 for carrying the golf ball head 2, and a beam generator 34 located outside the cavity 31 and capable of generating a high energy beam 341. The cavity 31 has a transmission window 311 made of a glass material. The gas delivery unit 32 has a gas storage tank 321 capable of storing a protective gas, and a gas delivery pipe 322 communicating with the gas storage bottle 321 and the cavity 31. The protective gas in the gas storage bottle 321 may be nitrogen gas. An inert gas such as helium or argon may protect the surface of the golf head 2 with an input protective gas and cool the golf head 2. The stage 33 is movable relative to the cavity 3', for example, by linear motion using a linear power train or by a rotary motion of a motor. The high-energy beam 341 that can be generated by the beam generator 34 is in the form of a strip, but may also be in the shape of a cylinder (R〇und), which is focused on the stage 33 through the transmission window 311. The ball head 2 is used to heat the surface of the golf club head 2. The beam generator 34 is also movable relative to the cavity. The relative movement of the beam generator 34 with the beam generator 34 can be controlled, and the high-energy beam 341 can be controlled to illuminate the path of the golf ball 2 for 7 Ι 29 Ό 842, so as to facilitate Control the size of the heated area. In fact, it is also possible to have only the movement of the stage 33 and the beam generator 34, as well as the control of the heated area. In the preferred embodiment, the beam generator 34 is a High Power Dipolar Laser that uses a wheel power of between 2000 W and 5000 W. The high-energy beam 341 has a wavelength of about 940 nm to 940 nm. The beam diameter is between 15 χ 1·5 and 2 to 9.0×20 mm 2 , depending on the focus range. And set. The depth and hardness can be controlled by controlling the power level of the output, and the displacement rate. At the same time, the heat treatment can be achieved by adjusting the gas delivery rate of the gas delivery unit 32 to control the cooling rate of the golf head 2. The so-called heat treatment is to apply a proper heating temperature, holding time, and cold portion rate to the metal material to adjust the structure of the metal material to obtain a predetermined mechanical property. Different materials have different heat treatment conditions, which are well known to those skilled in the art and can be easily accomplished, and will not be described in detail herein. The beam generator 34 of the preferred embodiment uses laser light, but it is also possible to use high power infrared light. The beam generator 34 is a solid laser, and the laser oscillating substance used may be Nd-YAG (Yttrium Aluminum Garent containing Ne 〇 dium ions), of course, it may be Nd Gi ^ s and 'for gas lasers Also suitable for use in the present invention, the laser oscillating material used may be carbon dioxide, helium-neon, or argon. When the surface hardening treatment is carried out in conjunction with Fig. 3, it can be generally carried out at room temperature. First, the golf club head 2 is positioned on a stage 1290842 33 in the cavity 31. Then, the gas delivery unit 32 is activated to fill the cavity 31 with a protective gas. Finally, the beam generator 34 is activated to cause the high energy beam 341 I to fall over the golf head 2. By manipulating the movement of the beam generator 34 and the stage 33, the high-energy beam 341 can travel along a predetermined path, and through the protection and cooling of the protective gas, the ball of the ball is 2 The predetermined area is heat-treated to harden the surface of the golf head 2, while the inside still retains the original hardness, forming a shape of external hard inner softness. During the irradiation, the temperature of the irradiated portion of the golf ball head 2 can be measured by temperature sensing such as an infrared thermometer. It is worth mentioning that the present invention directly heats the golf head 2 (single material). Of course, another material may be added to the golf head 2, and the high-energy beam 341 of the beam generator 34 is utilized. The applied material is melted with the golf head 2 to achieve an alloying effect. Since the present invention does not use the method of adding a ship covering material to improve the hardness: therefore, even under long-term impact, there is still no problem of peeling off, which is the same as that of the day, since only the surface layer is hardened, and the inner layer portion remains. The original softer features provide shock absorption and increased shot reduction. The above-mentioned method for surface hardening of the ball of the present invention in the tube: using the beam generator 34 to generate a high-energy light in a cylindrical shape or a strip shape, and the path is irradiated to the golf ball. And through the protective gas input by the unit 32, protecting and cooling the golf: the heated surface of the head raft to achieve a heat treatment effect, thereby improving the hardness of the local area of the head 2 and controlling The hardened area and the hardened layer depth 9 1290842 can indeed achieve the object of the present invention. However, the above is only the preferred embodiment of the present invention, and the scope of the present invention is not limited thereto, that is, the simple equivalent change and repair of the scope and the description of the invention. All of them are still within the scope of the patent of the present invention. [Simple description of the map]
