[Prior Art] Conventionally, a metal golf club head (hereinafter referred to as a club head) performs various heat treatments and surface treatments (hereinafter referred to as reforming treatment) for the purpose of achieving high strength and aesthetics, such as A method of performing a carburizing treatment (for example, Patent Document 2) by subjecting the inner surface to a hammering treatment to residual compressive stress (for example, Patent Document 1) is known. The metal head, especially the head with a hollow structure, is generally the most commonly used to weld the head produced by two or more members, but the welding between different materials is easy to cause insufficient joint strength due to the difference in the dissolution temperature. The problem arises. 'This problem is also well known to the public. In addition, there is also a golf club head in which an opening is provided on the top surface and the opening is closed by frP (for example, Patent Document 3). Patent Document 1: Japanese Special Opening 2 0 0 3 - 1 0 Japanese Patent Application Laid-Open No. Hei. No. Hei. No. Hei. No. Hei. Most of the reforming treatment loses its effect due to heating. According to (2) (2) 1326218, the test of the team of the present invention makes it clear that sometimes even the heat generated during welding causes the loss of effect. For example, the hammering treatment may cause the compressive stress to remain in the vicinity of the surface of the member to be treated, thereby improving the fatigue strength, but the high temperature generated by the heat during welding will cause the metal structure to recrystallize and cause the residual stress to disappear. . In view of the above problems, the present invention provides a method of manufacturing a golf club head capable of maintaining a reforming treatment effect by performing a process such as fusion by a method in which a calorific value is in a low temperature range after performing a reforming treatment. [Means for Solving the Problem] The present invention solves the above-mentioned problems by providing a method for manufacturing a golf club head. The method for manufacturing a golf club head according to the present invention is a hollow head structure formed of metal, and is characterized by After forming the head body portion having the opening in the top surface portion, the bottom surface portion, and the side surface portion, the inner surface of the head surface is subjected to a hammering process 'and then the opening is closed (Patent Patent No. 1). Since a large amount of stress remains in the vicinity of the top surface portion, the bottom surface portion, and the side surface portion of the face panel portion, that is, the peripheral portion of the head panel, the hammering treatment is applied to the portion to obtain a better effect. In the above case, it is preferable that the head face and the periphery of the head face form an integrated head face panel. When there is a welded portion between the head face and the periphery of the head face, the hammering process will have an adverse effect on the joint strength' and the joint portion may not be able to obtain the hammering effect. Further, the present invention solves the above-mentioned problems by providing a method for manufacturing a golf club head. The method for manufacturing the golf club head is as described in the first item of the application. Among them, the opening is closed by a resin, FRP or metal cover member (the second item of the patent application). Further, the present invention solves the above problems by providing a method of manufacturing a golf club head according to the second aspect of the patent application, wherein the cover member is formed by fitting, fitting or Assembled in a screwed manner (item 3 of the patent application). [Effects of the Invention] φ According to the method for manufacturing a golf club head according to the first to third aspects of the present application, it is possible to obtain a "can be used in a state in which the effect of the modification process is not caused in the molding process." The best results of a golf club head that produces an appearance with excellent strength in a simple and low-cost manner. [Embodiment] [Best Mode for Carrying Out the Invention] Φ Next, an embodiment of the present invention will be described with reference to the drawings. Embodiment 1 Fig. 1 is a perspective view showing an embodiment of a golf club head according to the present invention, which is a wooden head formed by a head body 1 and a head panel 2 and a top cover member 3. The head body 1 including the head face portion 4, the top surface portion 5, the bottom surface portion 6' side portion 7 and the stem neck portion 8, wherein the head face portion 4 forms a large opening with the center of the top surface portion 5, and is available from the head face The inner side surfaces of the bottom surface portion 6 and the side surface portion 7 are seen in the opening 9 and the top surface opening 10. The head panel 2 is (4) (4) 1326218 joined to the head face opening 9 of the head body 1 by welding. The head body 1 is formed by a gold-dense casting method such as titanium alloy. In the second drawing, the head face panel 2 is joined to the head face portion 4 and the head face opening 9 of the head body 1 by laser welding, electron beam welding or TIG (inert gas tungsten arc welding) welding. The above-described head panel 2 is formed of a titanium alloy rolled material having a composition of Ti-13V-llCr-3Al or Ti-15V-6Cr-3Al. The head panel 2 can improve the strength of the head face by using a higher rolling material than the head body 1 and other members. This will contribute to the high rebound characteristics of the head and the high moment of inertia. The material of the head panel 2 may be Ti-15V-3Cr-3Sn-3Al, Ti-15Mo-5Zr, Ti-15Mo-5Zr-3Al, Ti-3Al-8V-6Cr-4Mo-4Zr in addition to the above materials. , Ti-22V-4Ai. The third and fourth figures 'is an example of the other shape of the top surface opening 1 of the top surface portion 5 of the head body'. The shape of the opening is not limited to the shape shown in the first to fourth figures, and can be divided into three. Aliquots or 4 equal portions. The fifth and sixth figures are examples of shapes provided on the bottom surface opening π of the bottom surface portion 6 of the head body 1. And Fig. 7 is an example of the side opening 1 2 provided on the side portion 7 of the head body. The nozzle of the keystroke device is inserted from the opening portion 1 〇, the bottom surface opening 11 or the side opening 12 ′ provided in the head body 1 and faces the head surface and the head of the head body 1 from the inside. After the hammering process is performed around the surface, a cover member to be described later is attached to the opening of the head body. As the first! Any of the wood heads of the structure shown in Figures 7 are applicable to the examples of the present invention. -8 (5) (5) 1326218 Fig. 8 is a view of "inserting the nozzle 13 of the hammering device from the top opening 1 of the top surface portion 5, and performing the inner surface around the head surface and the head surface. In the same manner, the ninth figure is the opening from the bottom surface provided on the bottom surface portion 6, and the first 0 is the side opening 1 provided on the side surface portion 7. 2 A state diagram in which the nozzle 13 is inserted and subjected to a bead blasting process. Fig. 1 is a perspective view of the top cover member 3 for closing the opening provided in the top surface portion 5 of the head body 1. Fig. 1 is an external view of the head after the top cover member 3 is attached to the top opening 10 of the head body 1. The cover member 3 is a composite material formed by thermal compression stacking of carbon fiber cloth. For the beading material for hammering treatment, it is necessary to use a material having a hardness greater than that of the panel member. This is because once the hardness of the beading material is small, even if it collides with the head surface, local deformation cannot be sufficiently caused, so that it cannot be left. The reason for the compressive stress. The so-called bead material can be used, such as high carbon chromium bearing steel SUJ2 - which is most suitable for diameters above 1 m m. Further, a metal having an amorphous structure may be used as the bead material. This is because the hardness is high and the elastic range is large, so that it is difficult to form a composition deformation, and the compressive stress can be efficiently left on the head surface, and the durability of the excellent bead material can be obtained. In addition, the bead material should be made of non-angled materials, and the ball is ideal. This is because the beaded material with the angle will cause new flaws on the inner surface of the head face, and the notch effect caused by these new flaws may cause fatigue. Accordingly, it is most advantageous that the number of particles is small, the exchange is easy, and the ultrasonic surface of the smooth surface can be obtained. This is because jet-type beading requires the use of a large number of high-priced bead granules, and long-term use of the true -9-(6) (6) I3262l8 roundness of the damaged bead granules, so that a stable smooth surface cannot be obtained. As described above, although the fatigue strength derived from the residual stress is increased by performing the hammering treatment, the related hammering effect will be reduced by heating due to heating because the heating will cause the metal material to recrystallize, and The residual stress caused by the keystroke disappears, so it has to be said that the forming means for avoiding the head portion % being higher than the recrystallization temperature. The recrystallization temperature of the titanium alloy used for the head face member is 2500 □ or more. Therefore, it must be at least 200. (The following processing is carried out by following the processing. The adhesive used, for example, when the epoxy-based adhesive is 150 ° C ~ 0. (: the usable range, when the epoxy-based adhesive is denatured) 2 0 0 C or less. The completion of the work beyond the temperature range is not only difficult to obtain the bonding strength, but also the workability is not good. In addition, the cover member joint surface for opening the opening for closing the head body When the width is set to 1 or more, the joint strength of the head can be sufficiently ensured and the required durability can be obtained. Although the patent document 3 described above discloses a shape in which the joint portion with the lid member and the body is divided into The method of clamping the side and the back, but in order to ensure the embedded shape of the area required for joining, it is difficult to form and the cost is wide. In contrast, the present invention employs a simple planar joint portion, and in order to obtain a sufficient joint area, By providing the bonding tape with a width of 丨5, it is not only easy to form but also low in cost, and can ensure sufficient joint strength. The material used for the cover member can be the same as that of the head body. The material 1 bucket 'but preferably uses a material with a lower specific gravity than the body of the club head. For example, when a carbon fiber composite material is used, the center of gravity of the rod -10- (7) (7) 1326218 can be made due to the light weight. The position is set low, the moment of inertia of the head is increased, and the head volume is increased, so it is very suitable. In addition, the 'cover member can be made by injection molding. The resin can be made of ABS resin, polypropylene resin, polyamide resin, etc. The body may be mixed with glass fiber fragments or powder for the purpose of increasing strength, and a transparent appearance β may be formed by using a monomer. Further, the cover member may also be made of a metal material, particularly when used for a bottom portion. The position of the center of gravity of the head is lowered, and when the position of the center of gravity is deepened when used for the side portion, in order to avoid the high temperature generated by the welding when the head portion is joined, it is preferable to use a joint material having a lower temperature in a lower temperature range. And it can be used with the fitting, screw fixing or the fixing method of the above two. The method of performing the hammering is not limited to the way of inserting the fine nozzle, but also the thicker one. The method of sub-projecting the bead material. In the above method, 'the tube is thicker' is not easy to penetrate to the extent that the bead material hits the back surface of the head surface, so that the tube can be bent as shown in Fig. 13. Although the above is an embodiment describing the beading of the wood head in the golf club head, it can also be used for other hammering methods such as hammering and hammering, even if the mast head's invention is the same. It is possible to manufacture a golf club head that does not cause the deterioration treatment effect performed on the inner surface of the head face to disappear. [Industrial Applicability] The golf club head manufacturing method of the present invention can provide an excellent performance. Golf club head and golf club with strength and beauty. -11 - (8) (8) 1326218 [Simple description of the drawing] Figure 1: It is not used to close the head face member and the top surface.
