Abstract

A forging blank for a golf club head includes a casting prefabricated by investment casting and remained cinder holes therein. The casting comprises a predetermined bent portion, a head portion, and a hosel portion. The predetermined bent portion is linked between the head portion and the hosel portion. When the blank is forged by at least one forging mold, the predetermined bent portion of the blank can relatively attenuate deformations, and the forging pressure punched by the forging mold can eliminate the cinder holes of the blank. Thus, fewer forging molds are used to forge the construction of the golf club head.

【發明所屬之技術領域】 本發明係關於一種高爾夫桿頭之鍛壓初胚，特別是關於 先由鑄造製成一初胚，該初胚具有一預設彎折部，以便利 用該初胚快速鍛壓製造高爾夫桿頭之構造。 【先前技術】 習用高爾夫桿頭之製造方法，如第1圖所示，該製程首 先選用適當之碳鋼或合金鋼，將其輥軋抽拉製成1二金属 棒材9 0。接著，使該金屬棒材9 〇經過數個鍛模9丨a至9丨d進 行數次鍛壓處理。在鍛造過程中，由於各鍛模9丨&至9丨d之 模穴92a至92d係依序形成連續性形狀變化，因此可逐漸 該金屬棒材90的外形輪扉同步鍛壓成對應形狀之桿頭半g 品90a至90d。最後，將該桿頭半成品9〇d再經數道表面加 工，即可製得預定規格之桿頭成品〔未繪示〕。 雖然，該鍛造成型之桿頭成品具有鋼質均勻且結構強度 高等優點，但是由於鍛造過程使用過多鍛模9丨a至9丨d數 量，且該鍛模91a至91d之模穴92a至92d亦易因長期受壓變 形，而需經常更換，因而該製程存在開模及換模成本過 高，及無法使製得之桿頭成品維持規格一致等缺點。同 日守，在上述锻造製程期間，將該金屬棒材g 〇鍛壓至該桿頭 半成品9 0d即發生極大的變形量，一旦鋼質的延性不佳 時，該金屬棒材90將容易在欲預設彎折部位發生裂痕93， 因而降低桿頭成品之鍛造品質及良率。雖然^由高溫固溶 熱處理可提升金屬棒材9 0之延性及可鍛壓性，但此舉卻相 對延長製程’且過咼溫度亦促使該锻模g 1 a至g 1 d產生變[Technical field to which the invention belongs] The present invention relates to a forged primary embryo of a golf club head, and more particularly, to a primary embryo first made by casting. The primary embryo has a predetermined bending portion for rapid forging using the primary embryo. Manufacture golf club head structure. [Prior technology] As shown in Figure 1, the manufacturing method of a conventional golf club head is first selected by using appropriate carbon steel or alloy steel, and rolling and drawing it into a 12-metal rod 90. Next, the metal rod 90 is subjected to a number of forging treatments through a plurality of forging dies 9a to 9a and d. During the forging process, since the die cavities 92a to 92d of each of the forging dies 9 丨 & 9 丨 d sequentially form a continuous shape change, the contour wheel of the metal rod 90 can be gradually forged into a corresponding shape. Head half g products 90a to 90d. Finally, the semi-finished product of the club head 90d is subjected to several surface processing to obtain a finished club head of a predetermined specification [not shown]. Although the forged head product has the advantages of uniform steel and high structural strength, but because of the excessive number of forging dies 9 丨 a to 9 丨 d used in the forging process, and the cavity 92a to 92d of the forging dies 91a to 91d also It is easily deformed due to long-term compression and needs to be replaced frequently. Therefore, the process has the disadvantages of high mold opening and mold replacement costs, and inability to maintain the consistent specifications of the finished club head product. On the same day, during the above forging process, the metal rod g 0 was forged to 90 0d of the head semi-finished product, and a great amount of deformation occurred. Once the ductility of the steel is not good, the metal rod 90 will be easily It is assumed that cracks 93 occur at the bent portion, thereby reducing the forging quality and yield of the finished head. Although high temperature solid solution heat treatment can improve the ductility and malleability of metal bars 90, but this relatively prolongs the process' and the overheating temperature also causes the forging die g 1 a to g 1 d to change.

Description of the invention (2) Shape 'and reduce the service life and forging accuracy of the forging die 9 1 a to 9 1 d. Another conventional golf club head manufacturing method, as shown in Figure 2, is to use a dewax casting method to manufacture a finished club head. The process is to first prepare a mold 81, which is provided with a mold cavity 811, the mold cavity 81. It has the specifications of the finished product of the predetermined head; then, the wax liquid is injected into the mold cavity 8 丨 1 of the mold 8 丨 to form a wax mold 80; the wax mold 80 is taken out from the mold cavity 811, and the wax mold 8 is then removed. Dipping into a sand shell mold 82; then, heating the wax mold 80 to melt away from the sand shell mold 82, and then injecting a molten metal solution into the sand shell mold 82 to form a club head semi-finished product 83. Finally, the semi-finished product of the club head 8 3 is subjected to several surface processes, so that a club head product [not shown] of a predetermined specification can be obtained. Although the finished product of the cast head has reduced manufacturing costs and is suitable for production, it also has mechanical properties such as tensile strength, abrasion, and metal fatigue that are nearly equivalent to those of the forged head. Performance of the finished product. However, as shown in FIG. 3, the casting process is often accompanied by the formation of bad slag holes 84 (or sand holes, air holes) on the surface of the semi-finished product 83, so that the surface of the semi-finished product 8 3 is insufficiently polished or polished. When excessive, the finished product of the head will cause problems such as residual slag holes 84 or distortion of dimensional accuracy. Due to the poor fluidity of the molten metal, it cannot be filled in the sand shell mold 8 2 during casting, which also results in poor forming properties after casting. a On the other hand, for the iron-manganese aluminum alloy with poor casting properties [its viscosity is too high], the problem of the slag hole 84 is very serious, and even the finished product of the rod head of this material is good. rate. Moreover, for example, metal and alloy materials such as AISI θ86 ^ 〇θ steel and AISI 4130 steel, because of the poor fluidity of the molten metal ’, the molten metal of this metal material cannot be filled in the fine

Description of the invention (3) In the sand shell mold 82 formed by the mold cavity, a good shape of the initial embryo 83 cannot be obtained. However, the above-mentioned metal materials have a relatively low hardness range (approximately HRB 80 to 100), and if they are made into golf club heads, they have good shock absorption, excellent hitting feel, and ductility. Therefore, it is necessary to further modify the method 'in order to speed up the process and make the process there. The present invention improves the primary embryo. The primary embryo is provided with at least one pre-formed forging, and the predetermined bending portion can be made.

[Embodiment] * In order to make the above and other objects, features, and advantages of the present invention more obvious and easier, the following describes the preferred embodiments of the present invention, and in conjunction with the accompanying drawings, a detailed description is as follows. ¾ As shown in FIG. 4, the golf club head < forging primary embryo system of the first embodiment of the present invention includes a primary embryo. The primary embryo is usually made by casting method, and the casting method is preferably selected and manufactured using the conventional dewaxing method shown in Figure 2. The casting material used can be selected from various metals or alloys. For example, iron-manganese aluminum alloy, AISI 8620 steel or A ISI 4130 steel. After casting, the 'primary embryo 10' is set to form at least one preset bending portion 11 having a first end and a second end, and the first end is connected to a rod head 1 2, and the second end is connected to a set of handles 1 3. The predetermined bending angle α of the predetermined bending portion 11 is preferably 100.

In other words, in terms of the reserved processing amount of the initial embryo 10, it is equal to the subsequent forging compression amount, forging burr Sum of volume of removal and removal of surface force σ. Moreover, the volume of the reserved processing amount is preferably formed in the vertical direction of the striking panel of the finished head 10a. V reserved processing amount-V forging compression amount Forging burr removal amount + V surface processing removal amount Please refer to Figs. 4 to 8. The first embodiment of the present invention first uses at least one forging die 20 to forge the primary embryo 1 〇 The quantity of the forging die 20 can be adjusted according to the process requirement #. The forging die 20 is provided with a cavity 21, and the cavity 21 has a predetermined size specification of the finished head 10a. In the cavity 21 of the last forging die 20 used in the above forging, the cavity 21 of the forging die 20 can forge the primary embryo 10 under high pressure, and the preset bending portion 11 of the primary embryo 10 is adjusted. Angle, and adjust the thickness and cross-sectional area of the head portion 12 and the sleeve handle portion 13. It is worth noting that, since the present invention presets the preset bending portion 丨 丨 in the primary embryo 10, the unitary core 20 only needs to slightly adjust the bending angle q of the primary embryo 10. Because the angle adjustment causes only a slight amount of deformation, the present invention can effectively avoid the possibility of cracks in the bent portion due to excessive f-folding; and the structure of 10 is complete. As shown in FIG. 6, after forging, the semi-finished product of the head i 〇, usually a forged burr 1 102 is formed outward at the gap between the cavities 21 of the forging die 20. After cooling and shaping, the forged burr 102 is cut off. As shown in Figures 7 and 8, after forging, the rod

The face is in advance: 1: pressing, said, because the forging pressure can also fill the head semi-finished product 10, the surface slag hole 101, so it can also increase the head semi-finished product 10, surface processing requirements. After forging, the head is half formed. ^ A streamlined character is formed at least 0.5nm from the surface layer, which can improve the semi-finished product of the club head 10, and the surface mechanical properties of the surface layer can also keep the original casting Excellent setback, which can improve the structural strength of subsequent club head finished products. Since the present invention can effectively fill the slag holes 101 of the primary embryo through the composite process of casting and forging, even if the manufacturing process uses a casting material with poor casting properties such as iron-manganese aluminum alloy and easy slag holes, It will not affect the forging yield of the subsequent finished head 10a, so the range of material can be relatively expanded. In addition, since the preset bending part 丨 丨 of the preform 10 already has a bending angle «, the step of using high temperature solution heat treatment to improve the ductility can be omitted in the forging and pressing process. Even if the high temperature solid solution heat treatment step is still used in the forging and pressing process, the present invention only needs to be heated to a relatively low temperature [75 to 1050c], which is conducive to short and short processes and prolong the life of the forging die. On the other hand, by appropriately adding page 1236941 on page 11, V. Description of the invention (7) ------ Adding the modulus [section area / perimeter] of each part of the original embryo 10, the heat energy of the heat treatment can be reduced. The probability of loss is also conducive to maintaining the high temperature ductility of the original embryo. Please refer to Fig. 9 and Fig. 10, which show the forged primary embryo of a golf club head according to the second embodiment of the present invention. Compared with the first embodiment, the initial embryo 10 of the second embodiment is designed to have a thickness D and a cross-sectional area of the rod head 12, which are smaller than the thickness ^ and the cross-sectional area of the handle portion 13 'to form Relatively thin rod heads 1 2. After at least one forging, the thickness D of the head portion 12 is sufficient to form a panel portion 1 2 1 of the finished head portion 10a, and the preset bending portion 11 can form the One neck portion of the finished product 10a, and a handle portion 3, which can form a set of handles 13a of the finished product 10a. The finished product 10a, the back of the panel portion 121, Then it can be used to additionally combine a prefabricated weight 122 and 纟 ^; 5 ^ to form the body 12a of the finished head 10a. When the initial embryo 10 includes the thinner head 12 ', The primary embryo 10 will have a better modulus ratio, so even if the primary embryo 10 'uses iron-manganese aluminum alloy with poor casting properties, or AISI 8620 steel and AISI 4130 steel with poor fluidity, It can also relatively reduce the occurrence of slag holes or improve the casting yield. As mentioned above, compared with the conventional forging process, more forging dies must be used and the excessive deformation of the forging initial embryo also causes defects such as forging defects. Fig. 4 makes the preset bending part 丨 1 of the original embryo 10 by casting, which can indeed reduce the bending processing variation of the original embryo 10 And the total number of forging times, and ensuring the surface properties and structural strength of the finished head 10a, reducing slag holes 101, and thereby speeding up the process, reducing manufacturing costs, expanding the range of materials taken, and improving the forging quality.
