Abstract
Description
- 1. Field of the Invention
- The present invention relates to a golf club head and a method for manufacturing the golf club head.
- 2. Description of Related Art
- Conventionally, a striking plate of a golf club head is made by means of forging, pressing, or mechanical processing a metal alloy material to form a predetermined shape. The striking plate has a front face (i.e., the striking face) and a rear face. The front face of the striking plate is polished and processed to form plural grooves for increasing the friction, accuracy, and distance of striking. The rear face of the striking plate is preferably processed by electrolytic polishing, chemical polishing, or vibrational grinding/polishing to provide a highly polished surface or regular patterns. The highly polished surface has a surface roughness below 6.3 μm such that the rear face of the striking plate is capable of uniformly absorbing and dispersing the striking stress, avoiding generation of cracks in the rear face of the striking plate. After formation of a highly polished surface on the rear face of the striking plate, the striking plate can be mounted to a golf club head body through appropriate assembling procedures to form a golf club head.
- Although it is possible to form a highly polished surface on the rear face of the club head of a wooden club or iron club to improve the fatigue strength of the striking plate and to prolong the life of the striking plate, formation of the highly polished surface on the rear face of the striking plate must be completed before mounting the striking plate to the club head body. The highly polished surface may be impacted and thus scraped or damaged by the required devices and machines during the welding and mounting procedures as well as other processing and transport procedures. Damage to the highly polished surface largely and adversely affects its completeness, reducing the fatigue strength of the striking plate and adversely affecting the appearance of the product.
- An object of the present invention is to provide a golf club head, wherein a reinforcing metal layer having a hardness of 1000-4000 HV is formed by physical vapor deposition or plating on a highly polished surface of a rear face of the striking plate. The striking plate has improved abrasion-resistance to protect the highly polished surface during the assembling procedure. Further, the fatigue strength and the coefficient of restitution of the striking plate are improved, increasing the ratio of qualified products to disqualified products. The color of the reinforcing metal layer may be varied by means of changing the material for the reinforcing metal layer to thereby provide an aesthetically pleasing appearance of the rear face of the striking plate.
- Another object of the present invention is to provide a method for manufacturing a golf club head having a reinforcing metal layer formed on the rear face of the striking plate thereof.
- To achieve the aforementioned objects, the present invention provides a golf club head including a golf club head body and a striking plate. The golf club head body has a recession in a side thereof. The striking plate is embedded in the recession of the golf club head body. The striking plate includes a front face acting as a striking face and a rear face that is a highly polished surface. A reinforcing metal layer is formed on the highly polished surface of the striking plate and has a hardness higher than 1000 HV for protecting the highly polished surface.
- A method for manufacturing a golf club head in accordance with the present invention comprises forming a highly polished surface on a rear face of a striking plate; forming a reinforcing metal layer on the highly polished surface of the striking plate; inserting the striking plate into a golf club head body having a recession and a welding flange; deforming the welding flange of the golf club head body along an outer periphery of the striking plate; welding the welding flange to fuse the golf club head body and the striking plate along a boundary between the golf club head body and the striking plate; and finishing the welded portion of the golf club head and the striking plate.

FIG. 1 is a flowchart illustrating a method for manufacturing a golf club head in accordance with the present invention.FIG. 2 is a sectional view of a striking plate before formation of a reinforcing metal layer on therear face 12 of the striking plate. Referring toFIGS. 1 and 2 , a method for manufacturing a golf club head in accordance with the present invention comprises forming a highly polishedsurface 121 on a rear face of a striking plate 10 (step S100). Thestriking plate 10 is made of a material with a higher coefficient of restitution (COR), such as special steel (such as carbon steel of 4130), stainless steel (such as stainless steel of SUS174, 350, 455), or titanic alloy (such as an alloy of 6Al-4VTi). The material is forged, pressed, or mechanically processed to form a striking plate. Thestriking plate 10 can be used with a golf club head of a wooden club or iron club. - The
striking plate 10 generally includes afront face 11 and arear face 12. Thefront face 11 forms a striking face for striking a golf ball. Further, plural grooves 111 (FIG. 5 ) may be formed in thefront face 11 for increasing the friction, accuracy, and distance of striking of thestriking plate 10. Therear face 12 of thestriking plate 10 is processed by electrolytic polishing, chemical polishing, or vibrational grinding polishing to provide a highly polished surface with a surface roughness below 6.3 μm (preferably below 3.5 μm), thereby increasing the fatigue strength and the COR of thestriking plate 10. - The next step of the method for manufacturing a golf club head includes forming a reinforcing
metal layer 13 on the highlypolished surface 121 of the striking plate 10 (step S102). In particular, a reinforcingmetal layer 13 is formed on the highly polishedsurface 121 of thestriking plate 10 by physical vapor deposition (PVD) or plating. The physical vapor deposition includes evaporation and sputtering. -
FIG. 3 is a schematic view of an apparatus for proceeding with physical vapor deposition for forming a reinforcing metal layer on a rear face of the striking plate.FIG. 4 is a sectional view of the striking plate after formation of the reinforcing metal layer on the rear face of the striking plate. The reinforcingmetal layer 13 can be formed on the highly polishedsurface 121 of therear face 12 of thestriking plate 10 by an ion evaporation apparatus (FIG. 3 ) that may create a magnetic field and provide a shield. - As illustrated in
FIG. 3 , theion evaporation apparatus 30 includes anevaporation chamber 31, acarrier disc 32, anevaporation source 33, avacuum pump 34, aheating coil 35, and afilling hole 36. The surface of thestriking plate 10 is cleaned and dried. Then, thestriking plate 10 is placed into theevaporation chamber 31 and positioned on thecarrier disc 32, with therear face 12 of thestriking plate 10 facing upward. Next, at least oneevaporation material 331 is fixed on theevaporation source 33. Theevaporation material 331 is a metal material having a hardness of 1000-4000, particularly selected from a group consisting of titanium (Ti), zirconium (Zr), hafnium (Hf), chromium (Cr), and combinations thereof (see Table 1). - Next, the
evaporation chamber 31 is sealed and then vacuumed by thevacuum pump 34, and the temperature in theevaporation chamber 31 is raised by theheating coil 35. A reactive gas (such as nitrogen, ammonia, acetylene, ethylene, or a combination thereof) selected according to the need of product is filled into theevaporation chamber 31 via the filling hole 16. Then, theevaporation chamber 31 is connected to a positive pole, theevaporation material 331 is connected to a negative pole, and direct current is applied to proceed with evaporation procedure. Arc discharge occurs between the positive pole and the negative pole during the evaporation procedure, causing continuous evaporation and ionization of a portion of small particles of theevaporation material 331. The ionized particles of theevaporation material 331 react with the reactive gas and then move toward the highlypolished surface 121 of thestriking plate 10 under the action of negative bias voltage. Thus, a reinforcing metal layer 13 (FIG. 4 ) can be formed on the highlypolished surface 121 of thestriking plate 10 according to need. The reinforcingmetal layer 13 may have a thickness of 1-20 μm. The reinforcingmetal layer 13 is preferably a nitride or carbonic nitride of theevaporation material 331, such as TiN, ZrN, HfN, TiCxN1−x, ZrCxN1−x, TixZr1−xN, or CrCN.TABLE 1 composition of reinforcing hardness metal layer value (HV) color TiN 2400 golden yellow ZrN 3200 golden green HfN 2750 between yellow and green TiCxN1-x(x = 0.05-50) 2450-2900 between reddish and brown ZrCxN1-x(x = 0.05-20) 3250-3450 golden ZrCxN1-x(x > 0.9) 3300-3600 silver TixAl1-xN(x = 0.1-70) 2400-2900 golden, between brown and black TixZr1-xN(x = 20-80) 2400-3250 Golden CrCN 1500-2000 silver - In a case that high strength material (such as chromium) is used, the material can be directly plated on the highly
polished surface 121 of thestriking plate 20 to form a reinforcingmetal layer 13. - Since the nitride or carbonic nitride of metal formed by the physical vapor deposition includes various colors, the reinforcing
metal layer 13 covering therear face 12 of thestriking plate 10 provides an aesthetically pleasing colorful appearance and thus increases the value of the golf club. - Further, the thickness of the reinforcing
metal layer 13 can be selected according to need. For example, the thickness of the reinforcingmetal layer 13 is preferably 1-20 μm if the reinforcingmetal layer 13 is provided for improving the abrasion-resistance of the highlypolished surface 121 of thestriking plate 10. - Referring to
FIGS. 1, 5 , 6, and 7, the next step of the method for manufacturing a golf club head in accordance with the present invention is inserting thestriking plate 10 into a golf club head body 20 (step S104). The golfclub head body 20 includes arecession 21, a steppedportion 22, and awelding flange 23. The steppedportion 22 is formed along an inner periphery of therecession 21, and thewelding flange 23 is provided along an outer periphery of therecession 21. Further, the inner periphery of therecession 21 is inclined outward by an angle θ (smaller than 5) from a bottom portion thereof toward a top portion thereof. Further, an outer periphery of thestriking plate 10 is inclined outward by the angle θ from a bottom portion thereof toward a top portion thereof. - A smaller pressing
member 50 is used to press thestriking plate 10 to thereby insert thestriking plate 10 into therecession 21 of the golfclub head body 20. It is noted that thestriking plate 10 has been processed at thefront face 11 and the rear face 12 (including the highlypolished surface 121 and the reinforcing metal layer 13) thereof before inserting thestriking plate 10 into therecession 21 of thegolf club head 20. Thus, the reinforcingmetal layer 13 on therear face 12 of thestriking plate 10 may effectively protect the highlypolished surface 121 during the assembling procedure. - The
welding flange 23 is preferably integrally formed on the outer periphery of therecession 21. Preferably, weldingflange 23 has an outer periphery that inclines inward to form an inclined face (not labeled). Thus, when thewelding flange 23 is pressed, the metal material of thewelding flange 23 is apt to deform toward an inner side thereof, forming a thin sheet of metal that covers a boundary between the golfclub head body 20 and thestriking plate 10. - Referring to
FIGS. 1, 8 , 9, and 10, the next step of the method for manufacturing a golf club head in accordance with the present invention is deforming thewelding flange 23 of the golfclub head body 20 along the outer periphery of thestriking plate 10 by means of using the first pressingmember 51 and a second pressingmember 52 to press the welding flange 23 (step S106). - As illustrated in
FIG. 8 , the when thestriking plate 10 is inserted by tight fitting into therecession 21 of the golfclub head body 20, thewelding flange 23 of thegolf club head 20 is pressed by the first pressingmember 51, making primary deformation of thewelding flange 23. The first pressingmember 51 has a recessedportion 511 associated with thewelding flange 23. The recessedportion 511 has an inner periphery that is also inclined. Further, the recessedportion 511 has a depth slightly smaller than that a width of thewelding flange 23. Thus, the metal material of thewelding flange 23 deforms inward (i.e., the primary deformation) when the recessedportion 511 presses thewelding flange 23. - As illustrated in
FIG. 9 , the second pressingmember 22 is then used to press thewelding flange 23 of the golfclub head body 20 to make the final deformation of thewelding flange 23, forming a thin sheet of metal that covers a boundary between the golfclub head body 20 and thestriking plate 10. Preferably, agasket 60 is used to control the pressing extent of the second pressingmember 52, thereby controlling the thickness of the thin sheet of metal. - Referring to
FIG. 10 , the thickness of the thin sheet of metal is preferably controlled to be 0.80±0.20 mm. This thin sheet of metal acts as a filling material for filling a gap in the boundary between the golfclub head body 20 and thestriking plate 10 during welding. Also, this thin sheet of metal avoids the problems of excessive depression extent of the welding bead, insufficient penetration depth of welding, etc. - After the above four steps, the
striking plate 10 has tightly embedded into therecession 21 of the golfclub head body 20. The deformed thin sheet of metal prevents thestriking plate 10 from disengaging from the golfclub head body 20. Namely, a sufficient engaging strength exists between thestriking plate 10 and the golfclub head body 20. Thus, the thin sheet of metal, thestriking plate 10, and the golfclub head body 20 may be directly processed by milling or grinding so that the golfclub head body 20 and thestriking plate 10 form a flat striking surface, and appropriate surface finishing (e.g., the step S110) can be processed to rapidly provide a final product of a golf club head. - Referring to
FIGS. 1 and 11 , the next step of the method for manufacturing a golf club head in accordance with the present invention is welding thewelding flange 23 by high energy welding to fuse the golfclub head body 20 and thestriking plate 10 along the boundary between the golfclub head body 20 and the striking plate 10 (step S108). The high energy welding is preferably laser welding or electron-beam welding. Advantage of high energy welding includes fast welding speed, deep penetration of welding, wide welding bead (about 1.2-2.0 mm), small impact resulting from the welding heat, small deformation of the work piece, no surface deformation of the work piece resulting from high temperature oxidation, high bonding strength of welding bead, etc. Further, the gap (about 0-0.25 mm) in the boundary between thegolf club head 20 and thestriking plate 10 is controlled to be smaller than the diameter (about 0.3-0.5 mm) of the laser beams. Thus, the metal material on both sides of the boundary between the golfclub head body 20 and thestriking plate 10 can fuse completely by the laser beams. - Referring to
FIGS. 1 and 12 , the next step of the method for manufacturing a golf club head in accordance with the present invention is finishing the welded portion of the golf club head and the striking plate (step S110). The finishing may include sanding, grinding, polishing, mirror finishing, satin finishing, mechanic engraving, laser engraving, and printing of patterns or trade names, providing an aesthetically pleasing appearance and an identical specification for the club head products. - While the principles of this invention have been disclosed in connection with its specific embodiment, it should be understood by those skilled in the art that these descriptions are not intended to limit the scope of the invention, and that any modification and variation without departing the spirit of the invention is intended to be covered by the scope of this invention defined only by the appended claims.
