Description of the Invention: [Technical Field to Be Invented by the Invention] The present invention is a method for manufacturing a golf club head manufacturing method. a — kind of question [Prior Art] The existing golf irons are generally formed by precision. Since the existing iron heads are mostly forged, their performance often cannot meet the needs of people when hitting the ball. For example, the steel rod is made of medium and low carbon steel. The mast head is used as an example. Because of its soft material, it can be easily processed by the upper thread groove. Λ § ^ ^ and 4 for easy adjustment of the rod joint The page is inclined at an angle to the processing operation, and the bowl surface is soft, the wear resistance is not good, and the long-distance hitting function cannot be provided. The iron J box formed of high carbon steel or stainless steel is dried. For example, although the material is soft and hard, it has a good wear-resistant hitting distance, but it is difficult to increase the groove groove processing, the inclination angle of the joint, etc. It is not easy to adjust the pole of the iron. Even, based on the existing single-steel forming iron head problem, it has been carried out in a softer steel head. This is a hard-to-wear steel. It is welded, glued or inlaid by means of π.铁 "On the Keqing ball panel", the iron head made of this heterogeneous material, in order to overcome the iron head problem of the single "k early steel forming". However, in the above-mentioned heterogeneous combination of the iron stems, the head body and the panel are formed separately, and then the welding and gluing or (4) means that the & There is a defect of poor bonding between the head body and the ball striking panel. 201224156 SUMMARY OF THE INVENTION The main object of the present invention is to provide a golf iron head manufacturing process, which is designed to improve the shortcomings of poor bonding stability of the existing hard ball striking panel fixed on the head body. . For the purpose of achieving the foregoing, the golf iron rod manufacturing method designed by the present invention comprises: selecting a steel head type embryo head of an iron head type using a Sino-Silver steel or a low carbon steel material, the head blank comprising an integral forming The hitting surface; the heating temperature at the center of the hitting surface of the head blank; the 疋' flat is quenched to cool the head blank rapidly, so that the hitting surface of the head blank is formed by quenching - a hardened layer, and the hardness of the ball striking surface is radially decreasing from the center point; the wire groove is formed by a mechanical processing means on the ball striking surface; and the surface of the head blank is subjected to surface treatment to complete the manufacture of the iron head. The golf iron head manufacturing method has the softness of the head of the iron head, the hardness of the hitting surface is higher than the body height, and the hardness of the hitting surface is increased to increase the abrasion resistance of the hitting surface. The groove is not easy to wear, etc., and can prolong the service life, and the hardness of the hitting surface is increased. When hitting the ball, the striking function can be enhanced and the distance of the hitting ball can be enhanced. On the other hand, the head of the iron rod maintains the original body. The softness and the hardness of the medium and low carbon steels are combined with the rapid quenching method to form a high-hardness hitting surface to produce soft and hard composite characteristics, so that the iron head can be produced when hitting the ball. Good hitting feeling, and the joint of the iron head maintains the soft hardness characteristics of the original medium and low carbon steel, so it is easy to adjust the inclination angle of the rod joint 201224156. Furthermore, the present invention is a structure in which the iron head is integrally formed, so that the hitting surface is completely free from falling off, and the manufacturing steps of the existing heterogeneous iron head structure are effectively overcome, and the head body and the hitting ball are effectively overcome. Inter-panel storage: There are problems such as poorly coupled defects. [Embodiment] As shown in Fig. 1, the method for manufacturing the golf iron head of the present invention comprises the following steps: selecting medium carbon steel (carbon content 〇·25~〇.6〇%) or low carbon steel (carbon containing) The amount of 0.M or less) and other materials forming the iron head type of the head blank embryos, wherein the material such as carbon steel or low carbon steel can be formed into a club head blank by means of precision casting or forging, the head blank The utility model comprises an integrally formed ball striking surface; and the heating is heated to a predetermined quenching temperature at the center of the ball striking face of the club head blank by heating means, wherein the heating means can be selected by flame heating type, medium frequency/high frequency induction heating type Or electric heating type...equal force σ heat method, repeating the predetermined floating fire: degree conversion; f carbon head carbon fiber material carbon content of the dry head, and pre-tanning quenching temperature carbon content (%) Quenching Wentang, 0.12-0.18% —--------- \ w / 780 ± 0.17 ~ 0.23% ^75〇Τ?^ρ-~·— 0.22 ~0.29% 720^~2KV 0_27 ~0.34 % 690 + 2F^r 0.32 ~0.39% -------^ v/ 660 ±TrV 0.37 ~0.44% 630 ±2RV 0.42 ~0.50% 60〇T2RV 0_49 ~0.55% 570^2^0 " ---- Using flame heating means to heat the carbonaceous * 〇, 22~0 29% of the head blanks 201224156 as an example of this heating means in the step of heating the center of the head of the head blank Let the head blank be positioned horizontally upwards in the fixture - and adjust the flame gas volume (such as oxygen and acetylene) of the gas flame gun to medium, and the gas flame grabs the center of the hitting surface. The distance between the grab and the hitting surface is about 'the flame is applied to the center of the hitting surface to heat 72 〇 ± 25 ° C. During the heating process, the temperature of the hitting surface is measured by a thermometer.
