Abstract

Disclosed is a golf club head and a method for producing the same. The method comprises combining an enclosure with a striking faceplate. The enclosure includes an enclosure body, an opening defined by the enclosure body, and a plurality of protrusions. The enclosure body forms a stepped first joint face near the opening. A body of the striking faceplate encloses the opening of the enclosure and forms a second joint face corresponding to the first joint face. After the enclosure buts the striking faceplate, the protrusions of the enclosure protrude on the striking faceplate. Finally, a solder is mounted on the protrusions of the enclosure next to the striking faceplate. In a high temperature environment having a temperature lower than the melting points of the enclosure and the striking faceplate and higher than the melting point of the solder, the molten solder flows from each protrusion into the interface between the first and second joint faces by capillary in order to tightly connect the enclosure with the striking faceplate. As a result, the solder does not remain on the protrusions which simplifies a subsequent trimming operation.

[Technical field to which the invention belongs] The present invention relates to a club head and a method for manufacturing the same, and more particularly, to a golf club head and a method for manufacturing the same. [Previous technology] 5 In view of the prevalence of domestic holiday leisure, more and more athletes who like sports have chosen to invest in golf that can both relax and relax the body and mind. Under the leadership of this leisure style, Manufacturers at home and abroad have actively invested in related markets, and manufactured a large number of golf club heads that are more suitable for golf enthusiasts. 10 As shown in the first figure, a new patent case of "Combination structure of the shell of a wooden club head and a batting panel" of the Republic of China Patent Bulletin No. 421057 shows a hollow shell 10 and a Batting panel u. The casing 10 is formed with an opening 12. The hitting panel 11 is slightly larger than the opening 12 and covers the opening 12. Among them, the outer edge of the opening 12 of the casing 10 is provided with a ring 15-shaped convex strip 13, and the back periphery of the ball striking panel 11 is provided with an annular groove 14, and the annular convex strips 13 and the groove 14 are mutually Chimera. In addition, a welding layer 15 is provided on the mating surface of the casing 10 and the ball striking panel 11. The welding layer 15 is formed by melting and infiltration of a brazing material and cooling and solidifying, so as to form the casing. 10 Tightly weld the ball striking panel U. 20 Generally speaking, this kind of combined structure using the annular convex strips 13 and grooves 14 to be fitted to each other can increase the contact surface area between the casing 10 and the ball striking panel u, but is mostly limited by the welding layer 15 It is set in advance along the edge of the inner opening 12 of the casing 10. Therefore, the amount of the welding layer 15 will be limited by the length of the edge of the inner opening 12 of the casing 10. If it cannot be filled 6 589213 The amount of welding material will cause the welding effect to decrease, because the welding layer 15 is opened along the inside of the casing 10 in advance, and the edge of the mouth 12 is set, and then When the groove 14 on the spherical panel and the convex strip 13 on the casing 10 are mated with each other, the welding layer 15 is sandwiched by each other. When the welding layer 15 is melted in a high temperature environment, it must be It will overflow from the inside to the outside along the gap between the annular ribs 13 and the grooves 14 and condense on the outer surface of the casing 10 or the hitting panel U. Therefore, after the operation is completed, it must be manually or Welding on the outer surfaces of the shell body 10 and the ball striking panel 11 using processing machinery In addition to grinding layer 15, 10 is bound to increase in the overall number of time-consuming work. As shown in the first figure, a new patent case of the Republic of China Patent Bulletin No. 433066 "Joint Structure of Golf Club Head Shell and Hitting Panel (2)", this case discloses a case 20 and a casing made of metal.击球 板 片 21. The shell 20 is recessed inwardly with a groove 22 at the ball striking surface position, and a shoulder 23 is formed on the bottom wall of the groove 22. It is characterized in that a circumferential groove 24 is recessed inwardly from the peripheral edge wall of the ball striking panel 21, and the casing 20 extends from the shell wall corresponding to the groove 24 into the groove 24 to form a latch. The latching portion 25 is obtained by locally heating and deforming the casing 20 by melting and deforming. The casing 20 and the ball striking panel 21 are hard-welded. 20 In this joint structure, the heating partial housing 20 forms a catching portion 25 extending toward the recess 24, and the catching portion 25 and the recess 24 are engaged with each other to cooperate with brazing means, so that the housing 20 and the ball are hit. The panel pieces 21 are combined with each other, so that the bulletin and the previous bulletin will cause the problem of hard solder overflowing. 7 589213

In addition, 'under the engagement of the latching portion 25 and the recess 24', although the bonding strength between the housing 20 and the hitting panel 21 can be increased, it is limited that the latching portion 25 is a self-shell The body 20 is formed by external heat deformation. Once the shell 20 and the hitting panel 21 have been previously joined, the groove 24 5 疋 is covered by the shell 20 and the actuality of the groove 24 cannot be recognized from the outside. Position, so the user cannot match the position of the groove 24 very accurately for processing. Unless the mark is marked in advance or the size is accurately measured, the heat-deformed latching portion 25 can just align with the recess. Groove 24, resulting in the actual engagement effect is not as expected. 10 As shown in the third figure, the Republic of China Announcement No. 327606 "A method for joining a golf club head shell and a hitting panel sheet" invention patent case, this joining method exposes a hitting panel sheet 30 and is put into the head shell In front of the groove 32 of the body 3, the welding material 34 is placed on the shoulder surface 33 of the groove 32, and finally the impact panel piece 30 is inserted into the groove 32 of the head housing 31, so that the impact surface 15 is the plate 30 The bottom surface and the shoulder surface 33 sandwich the welding material 34, and then place it in a vacuum furnace to heat it. The butt joint material 34 melts and fills the abutting surface of the head housing 31 and the ball striking panel 30, so that the ball striking panel 3 〇 Welded to the head shell 鳢 31. This joining method uses the melting points of the head housing 31, the ball striking panel 30 and the welding material 34 to be different, so that the welding material 34 having a lower melting point is melt-filled in the head housing 31 and the striking panel. Between the sheets 30, the effect of welding the head housing 31 and the hitting panel sheet 30 is achieved. However, since the welding material 34 was powdered before being melted, when the welding material 34 was melted from a powdery solid to a liquid, the total volume of the welding material 34 shrank 8, which caused the welding material 34 to be insufficient to fill The gap between the head housing 31 and the hitting panel sheet 30 results in a gap between the head housing 31 and the hitting panel sheet 30 that is not completely filled by the welding material 34, so that the The joint strength between the head housing 31 and the hitting face sheet 30 is relatively greatly reduced, further affecting the structural stability of the entire golf club head. In order to compensate for the void caused by the shrinkage of the volume of the welding material 34 after melting, the conventional joining method solves this problem by increasing the laying amount of the welding material 34. However, once the laying amount of the welding material 34 increases, the welding material 34 melts. The total thickness of the welding material 34 flowing back into the gap between the head housing 31 and the hitting panel piece 30 will certainly increase accordingly, but the bonding strength between the head housing 31 and the hitting panel piece 30 will not be affected by The thickness of the welding material 34 is increased and relatively strengthened. On the contrary, the thickness of the welding material 34 is too thick, which increases the distance between the head housing 31 and the hitting panel piece 30, further leading to the struggle between the two. The decrease in strength also results in waste on the welding material 34. Therefore, how to achieve a balance between the bonding strength and the amount of the welding material 34 in this bulletin has formed a dilemma. This joining method also generates another problem, that is, because the welding material 34 is directly laid on the shoulder surface 33 of the groove 32, and then is inserted into the head housing 31 through the ball striking panel piece 30 pair. At the same time, the welding material 34 is clamped by the bottom of the hitting panel sheet 30. Therefore, once the joint processing of the head housing 31 and the hitting panel sheet 30 is completed, even if the amount of the welding material 34 is insufficient, As a result, a gap is generated between the head housing 31 and the hitting panel piece to, but also because the head housing 31 and the hitting ball V, 'V— 一 ·. + ..... 一 ". ϊΓ aSv ^ s /:: ^ 'The panel piece 3G has been completely gj' 'unable to re-separate the head housing η from the hitting panel y' to add the laying of welding material 34 t, and it is also impossible to add a bad mouth Remedies are easily found in quality control procedures, so the quality of products manufactured with this type of joining is a concern. [Summary of the Invention] Therefore, the object of the present invention is to provide a golf ball that can accurately preset the brazing material and effectively control the laying of the brazing material4, increase the contact surface area of the brazing material to improve the connection effect. Club head. Therefore, the golf club head of the present invention includes a shell, a hitting panel, and a brazing material. The shell, the striking panel and the hard fresh material are made of different metal materials, wherein the melting point of the brazing material is lower than the melting point of the shell and the striking panel. The casing has-a casing,-an opening defined by the casing, and a plurality of convex strips. The casing is formed with a stepped first joint surface adjacent to the opening. Each convex strip protrudes outward from the top edge of the first joint surface, and the protrusion directions of the convex strips are opposite to each other. Away from the striking panel, there is a body that closes the opening of the casing. A step-shaped second engaging surface corresponding to the first engaging surface is formed on the outer periphery of the body. Each convex strip of the casing is on the striking panel and the casing. After docking, it protrudes from the striking panel. The brazing material is preset on the convex strip of the casing and is adjacent to the outer periphery of the striking panel. According to the same inventive concept, the present invention further provides a method for manufacturing a golf club head, which sequentially includes a preliminary step, a docking step, a preset step, a processing step, and a forming step. In the preliminary step, components such as the shell, the striking surface 彳 i, and the brazing material are prepared, and the striking is performed in the docking step 589213

The main body of the panel closes the opening of the shell, and at the same time, the first and second joint surfaces are adhered to each other. The brazing material is preset on each convex strip of the casing in the presetting step, and is close to the outer periphery of the striking panel to become a half finished product. The semi-finished product is sent to the high temperature environment of the processing step. The high temperature environment can be vacuum or filled with inert gas. The high temperature environment is heated below the melting point of the shell and the impact panel, but higher than the melting point of the brazing material, and the melting point is lower. The brazing material melts at high temperatures. In the forming step, the molten brazing material flows into the gap between the first and second joint surfaces from each convex strip under the action of the capillary. The brazing material condenses on the first and second joint surfaces after cooling,至 将 ο

The shell and the striking panel are tightly connected and the golf club head is simultaneously formed. Since the brazing material is directly preset on each convex strip of the shell, and is relatively adjacent to the outer periphery of the striking panel, it provides a clear and fixed position to facilitate the assembly work. In addition, these are stepped separately The first and second joint surfaces that closely match each other can increase the contact surface area between the molten brazing material and the first and second joint surfaces of the specialty, thereby strengthening the bonding strength between the shells and the striking panels. At the same time, the brazing material flows inwardly between the first and second joint surfaces from each convex strip. Only the extremely thin brazing material is filled between the first and second joint surfaces, which can not only improve Combining strength and 20 can effectively control the laying amount of the brazing material, and it is not easy to produce the phenomenon of brazing material residue on each convex strip, which can simplify the process of processing and beautification. Due to the small amount of brazing material laying, the gap can be generated.% Can still easily add brazing material from these ridges and re-feed it to the processing step to maintain the yield quality of golf club heads. 11 589213

[Embodiment] The foregoing and other technical contents, features, and effects of the present invention will be clearly understood in the following detailed description of several preferred embodiments with reference to the drawings. It should be noted that in the following description, In this case, similar elements are represented by the same number. Referring to the fourth and fifth drawings, a preferred embodiment of the golf club head 4 according to the present invention is a wood head 'and includes a housing 41, a striking panel 42, and a brazing material 43. The casing 41, the striking panel 42 and the brazing material 43 are made of different metal materials. The melting point of the brazing material 43 is lower than the melting points of the casing 41 and the striking panel 42. The casing 41 has a casing 411, an opening 412 defined by the casing 411, and a plurality of convex strips 413. The housing 411 is formed with a first joint surface 414 adjacent to the opening 412. The first joint surface 414 is stepped, and each convex strip 413 protrudes outward from the top 15 edge of the first joint surface 414 at intervals. The protruding directions of the convex strips 413 are far from each other. The striking panel 42 has a main body 421 which closes the opening 412 of the casing 41, and a second joint surface 422 corresponding to the first joint surface 414 is formed on an outer peripheral edge 423. The second joint surface 422 Each step 413 of the casing 41 is protruding from the striking panel 42 after the casing 41 2 is in contact with the striking panel 42. Referring to the fifth and sixth figures at the same time, the manufacturing method of the golf club head according to the present invention includes a preliminary step 51, a docking step 52, a preset step 53, a processing step 54, and a forming step 55 in this order. Prepare the shell 41, the striking panel 42 and the brazing material 43 in the preliminary step 51, and close the opening 412 of the shell 4m with the striking body 42 of the striking panel 42 in the docking step 12 589213 职, Wei Ming 52. The first and second joint surfaces 414 and 422 are closely adhered to each other, so that each of the convex strips 413 of the outer shell 41 protrudes from the main body 421 of the striking panel 42. In the preset step 53, the hard soldering material 43 is formed. It is preset on each convex strip 413 of the casing 41, and the brazing material 43 is close to the outer periphery 423 of the striking panel 42 to become a semi-finished product. The semi-finished product is turned 180 degrees, so that the striking panel 42 is facing upwards, and then proceeds to processing step 54 for processing. The semi-finished product is sent into a high-temperature environment 10, which is a vacuum or filled with The heating furnace of inert gas is a vacuum heating furnace in this embodiment. The heating furnace keeps heating to the melting point of the brazing material 43 but is still lower than the melting temperature of the shell 41 and the striking panel 42. The welding material 43 itself has a low melting point and is melted, but the case 41 and the striking panel 42 are not melted. 15 The brazing material 43 enters the forming step 55 in a high-temperature environment. After melting, the brazing material 43 gradually flows inward from each of the convex strips 413 under the action of the capillary φ between the first and second bonding surfaces 414 and 422. The small gap is filled and connected to the first and second joint surfaces 414 and 422, and the semi-finished product is taken out and cooled. After the brazing material 43 is cooled and solidified, it will be tightly connected to the first and second joint surfaces. 414 and 422 so as to connect the shell 41 and the striking panel 42 to each other and form the golf club head 4 at the same time. In this embodiment, the brazing material 43 is limited to be preset on each convex strip 413 of the housing "41, and is relatively close to the outer periphery 423 of the striking panel 42. This assembly person can easily Ground the brazing material 43 to 13 589213

Placed in the correct position, thereby improving the yield of the preset step 53. Furthermore, the present invention fuses the brazing material 43 and flows inwardly between the first and second joint surfaces 414 and 422, thereby achieving the purpose of connecting the outer shell 41 and the striking panel 42 and correspondingly merging them through each other. The first and second joint surfaces 414 and 422 in a stepped shape 5 greatly increase the bonding surface area between the first and second joint surfaces 414 and 422 and the molten hard glowing material 43; The larger the strength is, the higher the connection strength is. Therefore, the step strength of the first and second bonding surfaces 414 and 422 is used to strengthen the bonding strength between the outer shell 41 and the striking panel 42. 10 In addition, between the first and second joint surfaces 414 and 422, only a very small amount of brazing material 43 can be contained in the flow, and the brazing material 43 condensed between the first and second joint surfaces 414 and 422 is As a thin layer, the shell 41 and the striking panel 42 can be tightly connected through the hard & material 43 so that the shell 41 and the striking panel 42 can be more firmly combined with each other. 15 On the other hand, the brazing material 43 is preset on each of the convex strips 413 in the presetting step 53 and is immediately adjacent to the outer periphery and edge 423 of the striking panel 42. The molten brazing material 43 flows inwardly into the small gap between the first and second joining surfaces 4H and 422, and almost all of the brazing material 43 is guided into the second and second joining surfaces 414 and 422 under the action of hair two. 20 Only a small part of the brazing material 43 remains on the convex strips 413, and will not cause any appearance protrusions or flashover phenomenon, so there is no need to add a modified polishing after the processing step 54 is finished. The operation can simplify the time required for the entire processing step 54. If the first and second connections 14 589213 1, ϊ-1: v 因 'are added due to the small amount of hard slabs 43 laying, a small amount of hard recordings 43 will be laid on top of them and sent to processing step M as filling gaps. In order to control the laying amount of the brazing material 43 at any time, a partial gap is generated between the mating surfaces 4U and 422, and the yield of the golf club head 4 can still be improved at each step 4i3 5- Remedy the problem of insufficient bonding force between the casing 41 and the striking panel 42 due to the low laying amount of the brazing material 43. Referring to the eighth and ninth diagrams, another preferred embodiment of the golf club head 4 of the present invention is almost equivalent to the above-embodiment, except that this preferred embodiment is used as an iron head. The shape of the shell 41 is slightly changed according to the method of hitting the 10 ball. However, in terms of the combination of the shell 41 and the strike panel 42, the position of the brazing material 43 and the flow direction of the brazing material 43 after melting. The language is the same as the previous embodiment, so the effects it can achieve are the same as the previous embodiment. To sum up, the golf club head 4 and the manufacturing method 15 of the present invention are filled with the brazing material 43 between the first and second joint surfaces 414 and 422 in a stepped manner to improve the Combined strength, and when the processing step 54 is not sent, the laying amount of the brazing material 43 can be increased or decreased according to the actual processing conditions, and the processed golf club head 4 does not need additional polishing work, so The objective of the present invention is indeed achieved. 20 However, the above is only a preferred embodiment of the present invention. When the scope of implementation of the present invention cannot be limited by this, that is, what is generally made according to the scope of the patent application and the description of the invention The simple equivalent changes and modifications should still fall within the scope of the patent on the date of issue. 15 589213 [Simplified description of the circle type] The first figure is a cross-sectional view of one of the new patent cases of the "combination structure of the shell of the golf club head and the hitting panel" of the Republic of China Patent Publication No. 421057; the second figure is the China Republic of China Patent Bulletin No. 433066 "Structure of golf club head shell and batting panel (2)" one of the new patent cases; the third figure is the use of Republic of China Bulletin No. 327606 "Golf club head shell and batting A method of joining a ball panel piece "invention patent is a partial cross-sectional view of joining a golf 10 head shell and a face plate; the fourth figure is a combined cross-sectional view of a preferred embodiment of a golf club head according to the present invention To illustrate the use of the preferred embodiment as a wooden club head, the fifth figure is a combined side view of one of the preferred embodiments, the sixth figure is a partial combined sectional view of one of the preferred embodiments, and the seventh figure is the present invention.
