Description of the Invention (/) The present invention relates to a method for manufacturing a golf club head and a striking panel structure thereof, particularly a method capable of stably integrating the striking panel in the head body, and The surface of the welded part of the striking panel and the head body is flat to facilitate the golf club head manufacturing method for subsequent surface processing and the structure design of the striking panel. In the past, most common golf club heads are structural designs of the same material (such as stainless steel or titanium alloy) as the head body and the striking panel. Among them, the titanium alloy material has high strength, light weight, and crisp sound. The best material for club heads is due to the disadvantages of high titanium alloy price, high manufacturing cost of casting and low product yield. At present, regarding the manufacture of golf club heads, when the stainless steel head body is combined with a titanium & gold strike panel, the two heterogeneous materials cannot be fixed together by ordinary ¥ connection between the stainless steel and the titanium alloy. There are two kinds of implementation methods: The first combination method is embedded. The embedded method is to make a hole before the bottom of the head body, and then insert the embedding mold into the inside of the head body, and cooperate with the tool to glue or strike the panel. The panel is fixedly fitted into the panel fixing section at the front end of the club head body. Then, a bottom plate corresponding to the hole at the bottom of the club head body is welded to close the opening to complete the combination of the embedded club body and the striking panel. The second bonding method is a brazed type, which is to align and strike the striking panel at the fixed section of the front panel of the head body, and then use brazing equipment to braze the joint between the striking panel and the head body. Although the aforementioned two consolidation methods respectively provide a national standard (CNS) A4 specification (21Q x 297 mm) that can fix the strike panel to the pole 3 ---------- ----- -^ —Order --------- line 00- (Please read the notes on the back before filling out this page) 553754 A7 B7 V. Description of the invention (>) The method of combining the head body, however, the two The method can not really provide a more industrially useful method of fixing, because: The first embedded head body and the striking panel are not bonded to each other because they are connected by a glue or tight fit. Structural type, its bonding strength is low, so when the user hits with the club, there is a danger that the strike panel will fall off due to multiple impacts. Moreover, the manufacturing method of the embedded combination requires The bottom of the head body is provided with a perforation provided by an insert mold, and after the striking panel is embedded in the head body, the bottom plate is used to close the perforation at the bottom of the head body, which is more complicated and inconvenient in manufacturing. As for the second brazing method Although the striking panel and the head body can be fixedly integrated, there is no risk of falling off, but the For the brazing method, the powdery welding material with a low melting point must be filled in the gap between the head body and the face plate, and then the whole is placed in a vacuum furnace or a high temperature furnace protected by an inert gas. Above the melting point of the welding material, the welding material will melt and fill the tiny gap between the body and the hitting panel by capillary action, and the body and the hitting panel will be welded together. The entire wood head must be placed under vacuum due to the brazing method. In a furnace or high-temperature furnace, the entire club head is affected by high temperature, which causes the club head to be deformed due to heat. Furthermore, the vacuum brazing method uses a low melting point welding material to melt into the tiny gap between the head body and the striking panel. The gap is welded, so the body and the hitting panel are connected through an intermediate medium (welding material), so the degree of bonding between the two must not be as strong as the strength of the homogeneous consolidation of the body and the hitting panel. But the brazing method will make Its strength becomes worse, and its color and lustre will change significantly, which will increase the inconvenience of post-processing, and meanwhile, the equipment used for brazing will be expensive.
