Abstract
A method for manufacturing a golf club head by which burrs can be removed without causing deviations in configuration and weight of a club head. Burrs 17 produced during a plastic deformation process are removed, using a laser processing machine. By setting the action of the laser processing machine in advance, it is possible to obtain a head body 1A of constant configuration and weight. Further, as all the burrs 17 can be removed at one burr removing step, manufacturing costs can be reduced.
Description
- a) Field of the Invention
- The present invention relates to a method for manufacturing a golf club head, through the plastic deformation of metallic materials.
- b) Prior Art
- A golf club is made up of a head and a shaft, and it is typically classified into three types, i.e., wood, iron and putter. An iron head, as is indicated by its naming, is formed from iron or other various kinds of metallic materials. Whilst wood club heads were formed from wood materials such as persimmon in the past, they are mainly formed from metallic materials in recent years, such as so-called metal wood.
- In general, methods for manufacturing a metallic golf club head are classified into two categories, i.e., casting and forging. Forging is superior to casting in that it can produce a golf club head of higher strength. Forging is a method by which a golf club head of a desired shape can be obtained by heating a metallic round rod material first, and then hammering it with a press or a hammer, using a die to thereby subject it to plastic deformation. In the broad sense of the term, “forging” includes deep drawing as well in which a rolled metallic plate is die cut and then subjected to deep drawing.
- For example, when a round rod material for a head material is heated and then hammered, using a die in the manufacture of an iron club head by forging, a surplus amount of the head material becomes a burr. If the burr is large, the forged head is deburred, using a trimming die before the head material gets cool.
- Normally, the head material is gradually finished to a final shape, through multi-stage forging process. Large burrs are produced at a comparatively early stage in such forging process. When the forged head material is close to the final shape as the forging process proceeds, surplus amount of the material is decreased, and thus burrs also become smaller.
- In the past, small burrs were typically removed by grinding process, using an endless paper, or by a cutting machine.
- In the case of grinding process, using an endless paper, however, as the grinding process is manually performed by an operator, the removing amount of burrs varies widely from operator to operator so that the constant configuration and weight of the heads could not be obtained. If the configuration and weight of heads vary, post-process trimming would be needed, thus causing unnecessary increase in manufacturing costs.
- On the other hand, in the case of machining process, using a cutting machine, the removal of burrs is comparatively easy in the outlines of a flat face portion, while it is substantially impossible to remove burrs in a hosel or a rise-up portion thereof. Accordingly, the removal of burrs in the hosel portion or a rise-up portion thereof eventually has to be carried out by a manual grinding by a human being.
- Accordingly, it is a main object of the present invention to provide a method for manufacturing a golf club head through the plastic deformation of a metallic material, which enables the removing of burrs without causing deviations in configuration and weight of a head.
- To attain the above object, there is provided, in accordance with an embodiment of the invention, a method for manufacturing a golf club head, having a face formed on a front and a shaft attachment portion formed on one side by subjecting a metallic material to plastic deformation step, wherein burrs produced during the plastic deformation step are removed, using a laser processing machine.
- Accordingly, it is possible to obtain a club head of constant configuration and weight, by setting the action of the laser processing machine in advance. Further, as all the burrs can be removed at one burr-removing step, manufacturing costs can be reduced
- Other objects, features and advantages of the invention will be apparent to those skilled in the art from the following description of the preferred embodiments of the invention, wherein reference is made to the accompanying drawings, of which:
- FIG. 1 is a perspective view of a golf club head which is under a forging process according to an embodiment of the invention.
- FIG. 2 is a section of a golf club head which is under a forging process according to an embodiment of the invention.
- FIG. 3 is a front view of a golf club head which is under a forging process according to an embodiment of the invention.
- FIG. 4 is a rear perspective view of a golf club head which is finished to a final shape according to an embodiment of the invention.
- FIG. 5 is a front view of a golf club head which is finished according to an embodiment of the invention.
- Hereinafter will be described embodiments of the invention with reference to the attached drawings, in which an iron golf club is described as an example.
- As shown in FIGS. 4 and 5, an iron golf club is made up of a
head 1 and ashaft 2, of which thehead 1 is made from a metallic material such as low-carbon steel, stainless steel or titanium-based alloy, including aface 3 for striking balls on a front, a sole 4 on a bottom, aheel 5 on one side, atoe 8 on the other side, ashaft attachment portion 6 provided at an upper part of theheal 5 for connecting theshaft 2 thereto and atop 7 at a top portion, respectively. A rear surface of thehead 1 is formed with aconcave portion 9 called “cavity”, substantially opposite to theface 3. Theconcave portion 9 includes arear face body 9A thereinside, defining an upperperipheral face 10 on its inside top, a lowerperipheral face 11 formed on its inside bottom, said lowerperipheral face 11 spaced a thickness h away from the sole 4, a firstperipheral face 12 formed on a first side and a secondperipheral face 13 formed on a second side, respectively.Reference numeral 14 designates lateral grooves called score lines formed on theface 3. In the center of therear face body 9A is formed asmall protrusion 15 which is laterally elongated to improve the design attractiveness. Agroove 16 is formed in the vicinity of therear face body 9A from a first sideperipheral surface 12 to a second sideperipheral surface 13 on the lowerperipheral surface 11. - Next, a method for manufacturing the
head 1 will be described. - For a raw material processing step, a round bar (not shown) made from a metallic material such as low carbon steel, stainless steel, titanium-based alloy is cut to a predetermined length to form a round bar material. Next, the round bar material is heated to form a
head body 1A through a hot forging step, as shown in FIGS. 1 to 3. As it is difficult to form thehead 1 at one stroke, the forging step includes rolling and multi-step forging such as preforming, intermediate forging and finish forging, using anupper die 15 and alower die 16. By performing the forging process through plural strokes, the head material is gradually stretched due to the plastic deformation in small steps so as to be finished to a final configuration. In the meantime, differentupper die 15 and lower die 16 are exclusively used for the above-mentioned preforming, intermediate forging, and final forging, respectively. -
Reference numeral 17 designates so-called burrs or flash produced during the forging step. As comparatively large burrs are created from the round bar material at a first forging stroke and in comparatively earlier forging processes, such burrs are removed, using a trimming die before the material gets cool. Smaller burrs are created as the forging step proceeds to bring the material close to a final configuration of the head. After the last forging stroke, thehead body 1A is placed in a receiving die (not shown), and then theburrs 17 are completely removed by cutting, using a laser processing machine (not shown). In that case, the laser irradiation from the laser processing machine is set in advance. - Through the forging step are formed a face
corresponding portion 3A, a solecorresponding portion 4A, a heelcorresponding portion 5A, a shaft attachment portioncorresponding portion 6A, a topcorresponding portion 7A, a toecorresponding portion 8A and a concave portioncorresponding portion 9′, which correspond to theface 3, sole 4,heel 5,shaft attachment portion 6,top 7,toe 8 andconcave portion 9, respectively. The concave portioncorresponding portion 9′ includes a rear face bodycorresponding portion 9′A thereinside, defining an upper peripheral facecorresponding portion 10A on its inside top, a lower peripheral facecorresponding portion 11A formed on its inside bottom, said lower peripheral facecorresponding portion 11A spaced a thickness H away from the solecorresponding portion 4A, a first peripheral facecorresponding portion 12A formed on a first side and a second peripheral facecorresponding portion 13A formed on a second side, respectively. In the meantime, the thickness H is larger than the aforesaid thickness h. - Next, the
head body 1A thus formed through the forging step is subjected to a cutting process. Any suitable cutting process is chosen, corresponding to the configuration and design of thehead 1 and theconcave portion 9 in a final product. Specifically, cutting process with a turning tool or a milling tool may be performed. In a preferred form of the invention, an end mill (not shown) such as a shank type milling cutter, having cutting edges on an outer peripheral face and an end face, is used to perform the cutting process. As shown in FIGS. 4 and 5, the rear face bodycorresponding portion 9′A and the lower peripheral facecorresponding portion 11A are cut to form therear face body 9A in a manner decreasing the thickness of theface 3 and the lowerperipheral surface 11 in a manner decreasing the thickness of the sole 4, respectively. The lowerperipheral surface 11 is concaved so as to define an undercut shape. In other words, the thickness h defined from the sole 4 and the lowerperipheral face 11 may be substantially the same on therear face body 9A side and thetip end 11Z side, or otherwise, may be smaller on therear face body 9A side than on thetip end 11Z side. During the cutting process, the aforesaidsmall protrusion 15 is formed in therear face body 9A, while thegroove 16 is formed adjacent to therear face body 9A on the lowerperipheral surface 11. - Thereafter, the finishing process is performed. The finishing process includes: surface polishing; the forming of the
lateral grooves 14; drilling for forming ahole 20 in a shaft center of theshaft attachment portion 6 for fitting the lower end of theshaft 2 thereinto; reaming; imprinting; plating; sandblasting; coloring, and the like. - According to the foregoing embodiment, there is provided a method for manufacturing a golf club head, having the
face 3 formed on a front and theshaft attachment portion 6 formed on one side by subjecting a metallic material to the plastic deformation, wherein theburrs 17 produced during the plastic deformation at the time of the forging step are removed, using a laser processing machine with the action thereof being set in advance, whereby the constant configuration and weight of thehead body 1A can be obtained. Further, as all theburrs 17 can be removed through a single step, the costs of removing theburrs 17 can be reduced to about ¼ to ⅕ of those of conventional methods, thus enabling the reduction of manufacturing costs. Furthermore, as a smooth cut surface can be obtained after removing theburrs 17, thus enabling an operator to carry out a cutting process with reference to the smooth cut surface. As a result, it is possible to make the configuration and weight of thehead body 1A constant, thus enabling an operator to proceed with the subsequent processes as originally designed, whereby it is possible to manufacture products with constant qualities and less deviations. - Incidentally, the present invention should not be limited to the foregoing embodiments, but may be variously modified within a scope of the invention. Although hot forging is taken as an example of the plastic deformation process, other plastic deformation processes may be employed, such as cold forging and cold pressing. Further, the
golf club head 1 should not be limited to an iron golf club, but may be a metallic wood golf club. Alternatively, thesmall protrusion 15 and thegroove 16 do not always have to be formed in theconcave portion 9, or otherwise, a protrusion of different dimension and configuration than that of the embodiment may be formed. It should be noted that a plurality of protrusions may be provided.
