Description

本発明は、ゴルフクラブ及びその製造方法に関するものである。   The present invention relates to a golf club and a manufacturing method thereof.

従来、この種のものとしてヘッド本体をＳ２０Ｃなどのいわゆる軟鉄、チタンやチタン合金、ステンレス鋼などで製造し、別途ウェイトとしてタングステン合金やステンレス鋼、銅合金などを嵌め込んだもの、或いはチタンやアルミといったものをフェースに嵌め込んだものが知られている（特許文献１）。   Conventionally, this type of head body is manufactured with so-called soft iron such as S20C, titanium, titanium alloy, stainless steel, etc., and separately inserted with tungsten alloy, stainless steel, copper alloy, etc. as a weight, or titanium or aluminum Such a device is known that is fitted on the face (Patent Document 1).

近年、より比重差を設けて高性能にするべくタングステン合金をウェイトとして嵌め込んだものが見られるようになった。この場合、タングステン合金製の部材は焼結方法で製造されるのが一般的だが、タングステン合金製部材そのものはあまり伸びが無く、それ自体をカシメて塑性変形させることは困難である。従って、現状ではネジ止め、接着、本体側の塑性変形によるカシメで接合される。この場合、ネジ止めと接着では部材の側面をストレートに加工する。タングステン合金は焼結時に約２割も収縮するため寸法精度がラフで、マシニングセンターなどで加工しなければならない。嵌め込む側のヘッド本体にも側面がストレートの凹部を形成し、両者を嵌め込むというものであった。
特開平１１−４９２２号公報 In recent years, a tungsten alloy is used as a weight in order to provide a higher specific gravity difference and higher performance. In this case, the tungsten alloy member is generally manufactured by a sintering method, but the tungsten alloy member itself does not stretch so much, and it is difficult to crimp and plastically deform itself. Therefore, under the present circumstances, it joins by screwing, adhesion | attachment, and caulking by the plastic deformation of the main body side. In this case, the side surface of the member is processed straight by screwing and bonding. Tungsten alloy shrinks by about 20% during sintering, so its dimensional accuracy is rough and must be processed by a machining center. The head main body on the side to be fitted has a concave portion with a straight side surface, and both are fitted.
Japanese Patent Laid-Open No. 11-4922

しかしながら、どんなに加工精度をあげても両者に加工公差が存在するため、僅かな隙間は不可避である。また、加工コストも高価となる。一方、本体側をカシメても、やはり寸法精度が高くないと隙間を無くすことは困難である。   However, no matter how high the processing accuracy is, there is a processing tolerance between them, so a slight gap is inevitable. Also, the processing cost is expensive. On the other hand, even if the main body side is caulked, it is difficult to eliminate the gap unless the dimensional accuracy is high.

そして、僅かでも隙間が存在すると、様々な問題がある。例えば接合強度が劣り、打撃中にズレが生じ、最悪の場合外れてしまう。或いは、バフ研磨などを行った際の研磨材が隙間に入り込み、それが後から染み出してくるということもある。ヘッド本体に軟鉄を用いた場合はめっきが必要だが、隙間に前処理液やめっき液が入り込み、めっき不良を起こしやすい。
本発明はこれらの問題に鑑み、複数の金属部材からなる一方の部材に嵌着受け部を凹状に形成すると共に、他方の部材を前記嵌着受け部に嵌着して一体化したヘッドにおいて、加工コストを極力抑え、なおかつ隙間の無いゴルフクラブ及びその製造方法ヘッドを提供するものである。 If there is even a slight gap, there are various problems. For example, the bonding strength is inferior, a deviation occurs during hitting, and it is removed in the worst case. Alternatively, the polishing material when buffing or the like is performed may enter the gap and ooze out later. When soft iron is used for the head body, plating is required, but pretreatment liquid and plating liquid enter the gaps, which tends to cause plating defects.
In view of these problems, the present invention provides a head in which a fitting receiving portion is formed in a concave shape in one member made of a plurality of metal members, and the other member is fitted and integrated in the fitting receiving portion. The present invention provides a golf club and a manufacturing method head thereof that suppress processing costs as much as possible and that have no gaps.

本発明における好適な実施の形態について、添付図面を参照して説明する。尚、以下に説明する実施の形態は、特許請求の範囲に記載された本発明の内容を限定するものではない。また、以下に説明される構成の全てが、本発明の必須要件であるとは限らない。   Preferred embodiments of the present invention will be described with reference to the accompanying drawings. The embodiments described below do not limit the contents of the present invention described in the claims. In addition, all of the configurations described below are not necessarily essential requirements of the present invention.

図１〜図３は実施例１を示しており、上端にグリップ（図示せず）を設けたシャフト１の下端に接続されるヘッド２は、シャフト１を接続するためのシャフト取り付け部たるホーゼル３を一側に突設し、前面にフェース４を、下部にソール５等を形成している。そして、ヘッド２はホーゼル３、フェース４及びソール５を有すると共に背面に嵌着受け部６を凹状に形成した一方の部材であるヘッド本体７と、嵌着受け部６に嵌着する平板状の他方の部材となるウエイト部材８Ｗとからなる。そして、ヘッド本体７はＳ２０Ｃの熱間鍛造で製造した鉄系金属により形成されているが、他の素材や鋳造など適宜選択できるものである。ウエイト部材８ｗはヘッド本体７より比重の大きい材質により一般に形成されるものであり、例えばタングステン或いはタングステン合金により形成されている。   1 to 3 show a first embodiment, in which a head 2 connected to a lower end of a shaft 1 provided with a grip (not shown) at an upper end is a hosel 3 serving as a shaft attaching portion for connecting the shaft 1. Projecting on one side, a face 4 is formed on the front surface, and a sole 5 is formed on the lower portion. The head 2 has a hosel 3, a face 4, and a sole 5, and a head body 7 that is one member having a fitting receiving portion 6 formed in a concave shape on the back surface, and a flat plate shape that fits on the fitting receiving portion 6. It consists of the weight member 8W used as the other member. The head body 7 is formed of an iron-based metal manufactured by S20C hot forging, but other materials, castings, and the like can be selected as appropriate. The weight member 8w is generally formed of a material having a specific gravity greater than that of the head body 7, and is formed of, for example, tungsten or a tungsten alloy.

そして、前記凹状の嵌着受け部６の開口部９の幅ａ（開口部幅）を、開口部９より該開口部９に対応してヘッド２の中心部に向かう方向の奥部10の幅ｂ（奥部幅）より次第に大きくなるように嵌着受け部６の内周面６ａはテーパー状に形成されている。奥部10は有底状に形成されている。一方ウエイト部材８ｗの外部に表れ前記開口部幅ａに対応する表部11の幅ｃ（表部幅）を開口部幅ａとほぼ等しく形成すると共に、表部幅ｃを該表部11よりヘッド２の中心側に向かい表部幅ｃに対応する裏部12の幅ｄ（裏部幅）より次第に大きくなるようにウエイト部材８ｗの外周面８ａをテーパー状に形成している。これにより各幅ａ,ｂ,ｃ,ｄは、ａ＝ｃ、ａ,ｃ＞ｄ＞ｂとなる。また、嵌着受け部６の深さｅはフェース部材８の表部11と裏部12間の厚みｆよりやや大きく形成している（ｅ＞ｆ）。尚、内周面６ａ、外周面８ａのそれぞれのテーパー角度ｘ,ｙは、３〜１５度、好ましくは５〜１０度となるようにほぼ同じ角度である。また、開口部幅ａ、奥部幅ｂ、表部幅ｃ、裏部幅ｄ、深さｅ及び厚みｆはそれぞれ同一断面箇所において測定される寸法である。そしてこのようなテーパー角度ｘ,ｙを有する内周面６ａ、外周面８ａは、全周にある必要はなく、ストレート部を有するなど少なくとも一部にテーパーが形成されていればよい。   Then, the width a (opening width) of the opening 9 of the concave fitting receiving portion 6 is set to the width of the back portion 10 in the direction from the opening 9 toward the center of the head 2 corresponding to the opening 9. The inner peripheral surface 6a of the fitting receiving portion 6 is formed in a taper shape so as to gradually become larger than b (back portion width). The back part 10 is formed in a bottomed shape. On the other hand, the width c (surface width) of the front portion 11 that appears outside the weight member 8w and corresponds to the opening width a is formed to be substantially equal to the opening width a, and the head width c is larger than the front portion 11 by the head. The outer peripheral surface 8a of the weight member 8w is formed in a taper shape so as to gradually become larger than the width d (back portion width) of the back portion 12 corresponding to the front portion width c. Accordingly, the widths a, b, c, and d are a = c and a, c> d> b. Further, the depth e of the fitting receiving portion 6 is formed to be slightly larger than the thickness f between the front portion 11 and the back portion 12 of the face member 8 (e> f). The taper angles x and y of the inner peripheral surface 6a and the outer peripheral surface 8a are substantially the same angle so as to be 3 to 15 degrees, preferably 5 to 10 degrees. Further, the opening width a, the back width b, the front width c, the back width d, the depth e, and the thickness f are dimensions measured at the same cross-sectional location. The inner circumferential surface 6a and the outer circumferential surface 8a having such taper angles x and y do not have to be on the entire circumference, and it is only necessary that the taper is formed at least in part such as having a straight portion.

次に製造方法について説明する。前記ヘッド本体７とウエイト部材８ｗはそれぞれ製造されており、図示しない台にヘッド本体７をセットし、そして上向きとした嵌着受け部６の開口部９にウエイト部材８ｗを落し込む様にして挿入し、さらに圧入する。この際ウエイト部材８ｗの表部幅ｃを開口部幅ａとほぼ等しく形成しているので、表部11が開口部９に嵌合するようになると共に、裏部12は内周面６ａの途中に配置されて内周面６ａに外周面11ａが嵌着し、この結果裏部12と奥部10との間には例えば厚みが２ｍｍ以下、好ましくは１ｍｍ以下の空隙14が形成されることになる。尚、開口部幅ａ、奥部幅ｂ、表部幅ｃ、裏部幅ｄ及び深さｅ、厚みｆはそれぞれ対応した箇所の幅、厚みを示しているものである。   Next, a manufacturing method will be described. The head main body 7 and the weight member 8w are respectively manufactured, and the head main body 7 is set on a table (not shown), and the weight member 8w is inserted into the opening 9 of the fitting receiving portion 6 facing upward. Then press fit. At this time, since the front part width c of the weight member 8w is formed to be substantially equal to the opening part width a, the front part 11 is fitted into the opening part 9, and the back part 12 is in the middle of the inner peripheral surface 6a. The outer peripheral surface 11a is fitted to the inner peripheral surface 6a, and as a result, a gap 14 having a thickness of 2 mm or less, preferably 1 mm or less is formed between the back portion 12 and the back portion 10. Become. Note that the opening width a, the depth width b, the front width c, the back width d and depth e, and the thickness f indicate the width and thickness of the corresponding portions, respectively.

ここで、嵌着受け部６又はウエイト部材８ｗの寸法精度がやや低くなっている場合、例えばウエイト部材８ｗの表部幅ｃや裏部幅ｄが所定寸法よりやや小さく形成されたような場合には、開口部９にウエイト部材８ｗを落し込む様にして挿入させて表部11が開口部９よりやや奥側に嵌合し、裏部12は内周面６ａの途中のやや奥側に配置されて内周面６ａに外周面８ａが嵌着する。このような際にも裏部12と奥部10との間には多少短くなった空隙14が形成されることになり、寸法精度がやや低くなったウエイト部材８ｗの取付けであっても空隙14を設けておくことにより、ウエイト部材８ｗの嵌着を可能にすることができる。   Here, when the dimensional accuracy of the fitting receiving part 6 or the weight member 8w is slightly low, for example, when the front part width c and the back part width d of the weight member 8w are formed slightly smaller than the predetermined dimension. Is inserted so that the weight member 8w is dropped into the opening 9, and the front portion 11 is fitted to the back side slightly from the opening portion 9, and the back portion 12 is arranged at the back side in the middle of the inner peripheral surface 6a. Thus, the outer peripheral surface 8a is fitted to the inner peripheral surface 6a. Even in such a case, a slightly shortened gap 14 is formed between the back portion 12 and the back portion 10, and even when the weight member 8w having a slightly reduced dimensional accuracy is attached, the gap 14 By providing, the weight member 8w can be fitted.

このようにして製造されたヘッド２をめっき処理した際には、めっき工程においてめっき液の染み込みは確認できなかった。これにより内周面６ａと外周面８ａとが密着していることが確認できた。また、ヘッドスピード４３ｍ／ｓ、２０００発の打撃試験を行ったが、ゴルフクラブとして強度上など何も問題が無かった。   When the head 2 manufactured in this way was subjected to a plating treatment, no penetration of the plating solution could be confirmed in the plating process. Thereby, it has confirmed that the inner peripheral surface 6a and the outer peripheral surface 8a were closely_contact | adhered. Further, although a hit test at a head speed of 43 m / s and 2000 shots was conducted, there was no problem in terms of strength as a golf club.

以上のように、前記実施例では開口部幅ａを奥部幅ｂより次第に大きくなるように嵌着受け部６の内周面６ａはテーパー状に形成され、表部幅ｃを開口部幅ａとほぼ等しく形成すると共に、表部幅ｃを裏部幅ｄより次第に大きくなるようにウエイト部材８ｗの外周面８ａをテーパー状に形成し、かつ嵌着受け部６の深さｅをフェース部材８の表部11と裏部12間の厚みｆよりやや大きく形成したことにより、ウエイト部材８ｗを嵌着受け部６に落し込むようにして嵌着させるようにしたことにより、嵌着受け部６やウエイト部材８ｗの寸法精度がやや低くなっていても両者を隙間等なく、しかも比較的安価に正確に嵌着することができる。   As described above, in the embodiment, the inner peripheral surface 6a of the fitting receiving portion 6 is formed in a tapered shape so that the opening width a is gradually larger than the depth width b, and the front width c is set to the opening width a. The outer peripheral surface 8a of the weight member 8w is tapered so that the front portion width c is gradually larger than the back portion width d, and the depth e of the fitting receiving portion 6 is set to be the face member 8. By forming the weight member 8w so as to drop into the fitting receiving portion 6 by forming it slightly larger than the thickness f between the front portion 11 and the back portion 12, the fitting receiving portion 6 and the weight member Even if the dimensional accuracy of 8w is slightly low, the two can be accurately fitted at a relatively low cost without a gap.

さらに、表部幅ｃを開口部幅ａとほぼ等しく形成することにより、表部11を開口部９に配置することができる。   Further, the front portion 11 can be disposed in the opening 9 by forming the front portion width c substantially equal to the opening width a.

また、内周面６ａ、外周面８ａのそれぞれのテーパー角度ｘ,ｙをほぼ同じ角度とすることにより、両者間を密着した状態で嵌着することができる。   Further, by setting the taper angles x and y of the inner peripheral surface 6a and the outer peripheral surface 8a to substantially the same angle, they can be fitted in a state where they are in close contact with each other.

図４〜図７は実施例２を示しており、前記実施例１と同一部分には同一符号を付し、その詳細な説明を省略する。ヘッド２はホーゼル３、ソール５を有すると共にフェース４に対応して嵌着受け部６を凹状に形成した一方の部材であるヘッド本体７と、嵌着受け部６に嵌着する平板状の他方の部材となるフェース部材８とからなる。そして、ヘッド本体７は鉄系金属により形成されており、フェース部材８はチタン或いはチタン合金により形成されており、両者は異なる金属からなる。   4 to 7 show the second embodiment, and the same parts as those in the first embodiment are denoted by the same reference numerals, and detailed description thereof is omitted. The head 2 has a hosel 3, a sole 5, and a head body 7 that is one member in which a fitting receiving portion 6 is formed in a concave shape corresponding to the face 4, and the other flat plate that is fitted to the fitting receiving portion 6. And a face member 8 serving as a member. The head body 7 is made of an iron-based metal, and the face member 8 is made of titanium or a titanium alloy, and both are made of different metals.

そして、前記凹状の嵌着受け部６の開口部９の幅ａ（開口部幅）を、開口部９より該開口部９に対応してヘッド２の中心部に向かう方向の奥部10の幅ｂ（奥部幅）より次第に大きくなるように嵌着受け部６の内周面６ａはテーパー状に形成されている。奥部10は有底状に形成されている。一方フェース部材８の外部に表れ前記開口部幅ａに対応する表部11の幅ｃ（表部幅）を開口部幅ａとほぼ等しく形成すると共に、表部幅ｃを該表部11よりヘッド２の中心側に向かい表部幅ｃに対応する裏部12の幅ｄ（裏部幅）より次第に大きくなるようにフェース部材８の外周面８ａをテーパー状に形成している。これにより各幅ａ,ｂ,ｃ,ｄは、ａ＝ｃ、ａ,ｃ＞ｄ＞ｂとなる。また、嵌着受け部６の深さｅはフェース部材８の表部11と裏部12間の厚みｆよりやや大きく形成している（ｅ＞ｆ）。尚、内周面６ａ、外周面８ａのそれぞれのテーパー角度ｘ,ｙは、３〜１５度、好ましくは５〜１０度となるようにほぼ同じ角度である。   Then, the width a (opening width) of the opening 9 of the concave fitting receiving portion 6 is set to the width of the back portion 10 in the direction from the opening 9 toward the center of the head 2 corresponding to the opening 9. The inner peripheral surface 6a of the fitting receiving portion 6 is formed in a taper shape so as to gradually become larger than b (back portion width). The back part 10 is formed in a bottomed shape. On the other hand, the width c (surface width) of the front portion 11 that appears outside the face member 8 and corresponds to the opening width a is formed to be substantially equal to the opening width a, and the head width c is larger than the front portion 11 by the head. The outer peripheral surface 8a of the face member 8 is formed in a taper shape so as to be gradually larger than the width d (back portion width) of the back portion 12 corresponding to the front portion width c. Accordingly, the widths a, b, c, and d are a = c and a, c> d> b. Further, the depth e of the fitting receiving portion 6 is formed to be slightly larger than the thickness f between the front portion 11 and the back portion 12 of the face member 8 (e> f). The taper angles x and y of the inner peripheral surface 6a and the outer peripheral surface 8a are substantially the same angle so as to be 3 to 15 degrees, preferably 5 to 10 degrees.

次に製造方法について説明する。前記ヘッド本体７とフェース部材８はそれぞれ製造されており、台13にヘッド本体７をセットし、そして上向きとした嵌着受け部６の開口部９にフェース部材８を落し込む様にして挿入し、さらに圧入する。この際フェース部材８の表部幅ｃを開口部幅ａとほぼ等しく形成しているので、表部11が開口部９に嵌合するようになると共に、裏部12は内周面６ａの途中に配置されて内周面６ａに外周面11ａが嵌着し、この結果裏部12と奥部10との間には空隙14が形成されることになる。   Next, a manufacturing method will be described. The head main body 7 and the face member 8 are respectively manufactured. The head main body 7 is set on the base 13, and the face member 8 is inserted into the opening 9 of the fitting receiving portion 6 facing upward. Then press fit. At this time, since the front part width c of the face member 8 is formed to be substantially equal to the opening part width a, the front part 11 is fitted into the opening part 9 and the back part 12 is in the middle of the inner peripheral surface 6a. The outer peripheral surface 11a is fitted to the inner peripheral surface 6a, and as a result, a gap 14 is formed between the back portion 12 and the back portion 10.

ここで、嵌着受け部６又はフェース部材８の寸法精度がやや低くなっている場合、例えばフェース部材８の表部幅ｃや裏部幅ｄが所定寸法よりやや小さく形成されたような場合には、開口部９にフェース部材８を落し込む様にして挿入させて表部11が開口部９よりやや奥側に嵌合し、裏部12は内周面６ａの途中のやや奥側に配置されて内周面６ａに外周面８ａが嵌着する。このような際にも裏部12と奥部10との間には多少短くなった空隙14が形成されることになり、寸法精度がやや低くなったフェース部材８の取付けであっても空隙14を設けておくことにより、フェース部材８の嵌着を可能にすることができる。   Here, when the dimensional accuracy of the fitting receiving part 6 or the face member 8 is slightly low, for example, when the front part width c and the back part width d of the face member 8 are formed slightly smaller than a predetermined dimension. The face member 8 is inserted so as to drop into the opening 9 so that the front part 11 is fitted slightly behind the opening 9 and the back part 12 is arranged slightly in the middle of the inner peripheral surface 6a. Thus, the outer peripheral surface 8a is fitted to the inner peripheral surface 6a. Even in such a case, a slightly shortened gap 14 is formed between the back portion 12 and the back portion 10, and even when the face member 8 is attached with slightly reduced dimensional accuracy, the gap 14 is formed. By providing this, the face member 8 can be fitted.

尚、フェース４の表面には銅めっき層４ａが形成されているとともに、さらに当該銅めっき層４ａの表面に腐食粗面層４ｂが形成されている。ここで銅めっき層４ａは、青化銅又は硫酸銅のいずれかでなり、少なくとも約20μm以上の厚さ寸法ｈを有するように形成されている。また、腐食粗面層４ｂは、銅めっき層４ａに対して後述する腐食処理を施すことにより生成された腐食生成物でなり、フェース面４表面に不均一な凹凸を有する粗面11Aを形成し、茶系色の銅めっき層と異なる紫色に配色されている。   A copper plating layer 4a is formed on the surface of the face 4, and a corrosion rough surface layer 4b is further formed on the surface of the copper plating layer 4a. Here, the copper plating layer 4a is made of either copper bromide or copper sulfate, and is formed to have a thickness dimension h of at least about 20 μm or more. The corroded rough surface layer 4b is a corrosive product generated by subjecting the copper plating layer 4a to the corrosive treatment described later, and forms a rough surface 11A having uneven unevenness on the face surface 4 surface. The color is purple, which is different from the brown copper plating layer.

次に、かかる構成でなるピッチングウェッジ１の製造方法について以下説明する。先ず、第１工程として、フェース４を研磨することによりその表面を平滑にする。   Next, a method for manufacturing the pitching wedge 1 having such a configuration will be described below. First, as a first step, the face 4 is polished to smooth its surface.

かかる工程に加え、第２工程として、フェース４を除きその表面全体にマスキングシール（図示せず）を貼付することにより、フェース４を露出させるとともに、当該フェース４以外の部分をマスキングテープで被覆する。   In addition to this step, as a second step, a masking seal (not shown) is affixed to the entire surface except for the face 4 to expose the face 4 and to cover the portions other than the face 4 with a masking tape. .

この状態で、第３工程として、公知の電気めっき方法により、青化銅又は硫化銅を用いた銅めっき処理をヘッド本体９に施すことにより、露出したフェース４表面に青化銅又は硫化銅を析出させ、先ず約３０μmの厚さ寸法ｈを有する銅めっき層４ａをフェース４に形成させる。   In this state, as a third step, a copper plating process using copper bromide or copper sulfide is applied to the head body 9 by a known electroplating method, so that copper cyanide or copper sulfide is exposed on the exposed face 4 surface. First, a copper plating layer 4 a having a thickness dimension h of about 30 μm is formed on the face 4.

次に、第４工程として、フェース４に形成した銅めっき層４ａの表面を、布バフ（図示せず）を用いて研磨することにより平滑にしミラー加工した後、約70℃〜80℃のトリクレン（トリクロロエチレン）の液体を用いてトリクレン洗浄することによりフェース４から油脂やその他の汚れを除去し、その後、このトリクレン洗浄により温められたフェース部材８を放冷して冷却する。   Next, as a fourth step, the surface of the copper plating layer 4a formed on the face 4 is smoothed and polished by polishing with a cloth buff (not shown), and then the tricrene at about 70 ° C. to 80 ° C. Oil and fat and other dirt are removed from the face 4 by trichlene cleaning using a liquid of (trichloroethylene), and then the face member 8 warmed by this trichlene cleaning is allowed to cool and cool.

続いて、第５工程として、硫化カリウム（K2O）と、酢酸銅（(CＨ3COO)Cu・Ｈ2O）と、カリウムみょうばん（AlK(SO4)2・12Ｈ2O）とを混合することにより予め生成された常温の腐食液の中に約５秒間だけ浸し、当該表面に積層した銅めっき層４ａを腐食させる腐食処理を行う。これにより銅めっき層４ａの表面に、不均一な凹凸を有する粗面４ｃでなり、かつ紫色に変色して当該銅めっき層４ａと異なる配色となる腐食粗面層４ｂを形成する。   Subsequently, as a fifth step, potassium sulfide (K2O), copper acetate ((CH3COO) Cu · H2O), and potassium alum (AlK (SO4) 2 · 12H2O) are mixed at room temperature. A corrosion treatment is performed in which the copper plating layer 4a laminated on the surface is corroded by being immersed in the corrosive liquid for about 5 seconds. As a result, the corroded rough surface layer 4b is formed on the surface of the copper plating layer 4a. The corroded rough surface layer 4b has a rough surface 4c having uneven unevenness and is colored purple and has a color scheme different from the copper plating layer 4a.

実際上、この実施の形態の場合、腐食液に約５秒間だけ浸すことにより、フェース４に積層した銅めっき層４ａが腐食されて腐食粗面層４ｂが形成された場合であっても、腐食されない銅めっき層４ａの厚さ寸法ｈが少なくとも約20μm以上に形成し得るようになされている。   Actually, in the case of this embodiment, even if the copper plating layer 4a laminated on the face 4 is corroded by being immersed in the corrosive liquid for about 5 seconds, the corrosion rough surface layer 4b is formed. The thickness h of the copper plating layer 4a not to be formed can be formed to be at least about 20 μm or more.

そして、第６工程として、湯洗することにより腐食粗面層４ｂの表面に付着した腐食液などを除去し、その後乾燥させた後にマスキングテープを取り除くことにより、フェース面４のみが不均一な粗面４ｃで、かつ紫色に配色したものを形成し得るようになされている。   Then, as a sixth step, the corrosive liquid adhering to the surface of the corroded rough surface layer 4b is removed by washing with hot water, and after drying, the masking tape is removed, so that only the face surface 4 is unevenly roughened. The surface 4c can be formed in a purple color.

以上の構成によれば、ショット時にゴルフボール（図示せず）が直接接触するフェース面４を腐食粗面層４ｂで形成することにより、粗面４ｃの不均一な凹凸にゴルフボールが接触するので、当該フェース４とゴルフボールとの摩擦を一段と大きくすることができ、かくしてゴルフボールに対して従来よりも一段とスピンをかけることができる。   According to the above configuration, the golf ball comes into contact with the uneven irregularities of the rough surface 4c by forming the face surface 4 with the corroded rough surface layer 4b, which is in direct contact with the golf ball (not shown) during a shot. The friction between the face 4 and the golf ball can be further increased, and thus the golf ball can be spun more than before.

また、銅めっき層４ａを腐食液を用いて腐食させることにより、一段と不均一な凹凸の粗面４ｃをフェース面４に形成することができ、かくしてフェース面４とゴルフボールとの摩擦をさらに大きくすることができる。   Further, by corroding the copper plating layer 4a with a corrosive liquid, it is possible to form a rough surface 4c having unevenness more unevenly on the face surface 4, thereby further increasing the friction between the face surface 4 and the golf ball. can do.

以上のように、前記実施例では開口部幅ａを奥部幅ｂより次第に大きくなるように嵌着受け部６の内周面６ａはテーパー状に形成され、表部幅ｃを開口部幅ａとほぼ等しく形成すると共に、表部幅ｃを裏部幅ｄより次第に大きくなるようにフェース部材８の外周面８ａをテーパー状に形成し、かつ嵌着受け部６の深さｅをフェース部材８の表部11と裏部12間の厚みｆよりやや大きく形成したことにより、フェース部材８を嵌着受け部６に落し込むようにして嵌着させるようにしたことにより、嵌着受け部６やフェース部材８の寸法精度がやや低くなっていても両者を隙間等なく、しかも比較的安価に正確に嵌着することができる。また、フェース部材８や嵌着受け部６にめっき層（図示せず）を表面に形成した場合には、寸法が所定のものより多少異なってしまうが、このような場合にもフェース部材８を嵌着受け部６に落し込むようにして嵌着させるようにしたことにより正確に取り付けできる。   As described above, in the embodiment, the inner peripheral surface 6a of the fitting receiving portion 6 is formed in a tapered shape so that the opening width a is gradually larger than the depth width b, and the front width c is set to the opening width a. The outer peripheral surface 8a of the face member 8 is formed in a tapered shape so that the front portion width c is gradually larger than the back portion width d, and the depth e of the fitting receiving portion 6 is set to be the face member 8. By forming the face member 8 so as to drop into the fitting receiving portion 6, the fitting receiving portion 6 and the face member are formed. Even if the dimensional accuracy of 8 is slightly low, the two can be accurately fitted at a relatively low cost without a gap. Further, when a plating layer (not shown) is formed on the surface of the face member 8 or the fitting receiving portion 6, the dimensions are slightly different from the predetermined ones. It can be attached accurately by being fitted to the fitting receiving portion 6 so as to drop.

さらに、表部幅ｃを開口部幅ａとほぼ等しく形成することにより、表部11を開口部９に配置することができる。   Further, the front portion 11 can be disposed in the opening 9 by forming the front portion width c substantially equal to the opening width a.

また、内周面６ａ、外周面８ａのそれぞれのテーパー角度ｘ,ｙをほぼ同じ角度とすることにより、両者間を密着した状態で嵌着することができる。   Further, by setting the taper angles x and y of the inner peripheral surface 6a and the outer peripheral surface 8a to substantially the same angle, they can be fitted in a state where they are in close contact with each other.

図８〜９は実施例３を示しており、前記実施例２と同一部分には同一符号を付し、その詳細な説明を省略する。実施例３においては嵌着受け部６の内周面６ａの上端に突起21を一体に形成しておき、一方フェース部材８の表部11の縁部に面取り部22を形成しておく。そして製造時においてはフェース部材８を嵌着受け部６に落し込むようにして嵌着した後、さらにヘッド本体７、特に突起21又はその周辺を押し潰すことにより面取り部22を埋めて押し潰し部23を形成して両者を固着したものである。   8 to 9 show a third embodiment, and the same parts as those of the second embodiment are denoted by the same reference numerals, and detailed description thereof is omitted. In the third embodiment, a protrusion 21 is integrally formed on the upper end of the inner peripheral surface 6 a of the fitting receiving portion 6, while a chamfered portion 22 is formed on the edge of the front portion 11 of the face member 8. At the time of manufacture, the face member 8 is fitted so as to drop into the fitting receiving portion 6, and then the chamfered portion 22 is filled by crushing the head body 7, particularly the protrusion 21 or its periphery, thereby crushing the crushing portion 23. It is formed and both are fixed.

このように、突起21を押し潰すことによりフェース部材８の面取り部22を埋めて両者の抜け止めを図ることができる。   In this way, by crushing the protrusion 21, the chamfered portion 22 of the face member 8 can be filled and both can be prevented from coming off.

図10〜11は実施例４を示しており、前記実施例２と同一部分には同一符号を付し、その詳細な説明を省略する。実施例４においては、ヘッド本体７の凹状の嵌着受け部６の奥部10に、後方へ向けて貫通する貫通孔31を形成することにより、フェース部材８の裏部12が貫通孔31を介して後方にあらわれるものである。   10 to 11 show a fourth embodiment, and the same parts as those of the second embodiment are denoted by the same reference numerals, and detailed description thereof is omitted. In the fourth embodiment, the back portion 12 of the face member 8 forms the through-hole 31 by forming a through-hole 31 that penetrates backward in the back portion 10 of the concave fitting receiving portion 6 of the head body 7. It appears behind.

このようにヘッド本体７の凹状の嵌着受け部６の奥部10に貫通孔31を形成して、フェース部材８が後方にあらわれるようにすることにより、打撃時におけるフェース部材８の弾性変形を大きくすることができる。   In this way, the through hole 31 is formed in the back portion 10 of the concave fitting receiving portion 6 of the head main body 7 so that the face member 8 appears rearward, so that the elastic deformation of the face member 8 at the time of impact is achieved. Can be bigger.

図12〜13は実施例５を示しており、ヘッド本体７のソール５の略中央に嵌着受け部６を形成すると共に、該嵌着受け部６にソール部材41を嵌着したものである。そして、嵌着受け部６の開口部幅ａを、奥部幅ｂより次第に大きくなるように嵌着受け部６の内周面６ａはテーパー状に形成され、一方ソール部材41の表部幅ｃを開口部幅ａとほぼ等しく形成すると共に、表部幅ｃを裏部幅ｄより次第に大きくなるようにソール部材41の外周面41ａをテーパー状に形成している。また、嵌着受け部６の深さｅはソール部材41の表部11と裏部12間の厚みｅよりやや大きく形成している。   12 to 13 show a fifth embodiment, in which a fitting receiving portion 6 is formed at substantially the center of the sole 5 of the head body 7 and a sole member 41 is fitted to the fitting receiving portion 6. . And the inner peripheral surface 6a of the fitting receiving part 6 is formed in a taper shape so that the opening width a of the fitting receiving part 6 becomes gradually larger than the inner part width b, while the front part width c of the sole member 41 is formed. Is formed substantially equal to the opening width a, and the outer peripheral surface 41a of the sole member 41 is formed in a tapered shape so that the front width c is gradually larger than the back width d. Further, the depth e of the fitting receiving portion 6 is formed to be slightly larger than the thickness e between the front portion 11 and the back portion 12 of the sole member 41.

したがって、例えばソール部材41の表部幅ｃや裏部幅ｄが所定寸法よりやや小さく形成されたような場合には、開口部９にソール部材41を落し込む様にして挿入させて表部11が開口部９よりやや奥側に嵌合し、裏部12は内周面６ａの途中のやや奥側に配置されて内周面６ａに外周面41ａが嵌着することにより、嵌着受け部６やソール部材41の寸法精度がやや低くなっていても両者を隙間等なく、しかも比較的安価に正確に嵌着することができる。   Therefore, for example, when the front part width c and the back part width d of the sole member 41 are formed to be slightly smaller than a predetermined dimension, the sole member 41 is inserted into the opening 9 so as to drop into the front part 11. Is fitted on the back side slightly from the opening 9, and the back part 12 is arranged on the back side slightly in the middle of the inner peripheral surface 6a, and the outer peripheral surface 41a is fitted on the inner peripheral surface 6a. 6 and the sole member 41 can be fitted accurately at a relatively low cost without any gaps even if the dimensional accuracy of the sole member 41 is slightly low.

以上のように本発明にかかるゴルフクラブの製造方法はヘッドの後部に嵌着するバック部材の取付け等の用途にも適用できる。   As described above, the golf club manufacturing method according to the present invention can also be applied to uses such as attachment of a back member fitted to the rear portion of the head.
