Description

本考案はゴルフクラブヘッドの製造法、詳しく言えばろう付けによりゴルフクラブヘッドのユニットを接合する接合方法に関するものである。   The present invention relates to a method for manufacturing a golf club head, and more particularly to a joining method for joining units of a golf club head by brazing.

特許文献１に掲示されたろう付け（Brazing）によるゴルフクラブヘッドのユニットの接合方法は、クラブ生産作業において鋳造方法または鍛造方法によりクラブの一部分のユニットを生産し、生産されたこれらのユニットを保存（材料用意）・搬送した後、ろう付けにより接合することである。この間ユニットの表面に酸化層が生じ易いためろう付けの物性を変えることがある。例えばもっとも使用されているステンレス材料と空気中の酸素とは三酸化二クロム（Ｃｒ2Ｏ3）の不活性膜を生成し、このような不活性膜は後続工程におけるろう付けのろう材とステンレスの表面との接着効果に支障をきたす。従ってろう付けにより接合する前に接合待ちのユニットの表面に表面処理（例えば酸洗、洗浄などの複雑なステップ）を施す必要がある。また一部分のろう付けのろう材は接合待ちの金属母材に対し反応するため、母材の成分及び性能を変化させ、母材を破裂させるという欠点がある。 In the method of joining golf club head units by brazing as disclosed in Patent Document 1, a unit of a part of a club is produced by a casting method or a forging method in a club production operation, and these produced units are stored ( (Material preparation) ・ After transporting, joining by brazing. During this time, an oxidation layer is likely to be formed on the surface of the unit, so the physical properties of brazing may be changed. For example, the most used stainless steel material and oxygen in the air produce an inert film of dichromium trioxide (Cr 2 O 3 ), which is used for brazing brazing material and stainless steel in subsequent processes. It interferes with the adhesive effect with the surface. Therefore, it is necessary to perform surface treatment (for example, complicated steps such as pickling and washing) on the surfaces of the units waiting to be joined before joining by brazing. Further, a part of the brazing filler metal reacts with the metal base material waiting to be joined, so that there is a disadvantage that the base material is ruptured by changing the composition and performance of the base material.

米国特許５，８７１，４８０号US Pat. No. 5,871,480

本発明の主な目的はろう付けによる接合品質を向上可能なゴルフクラブヘッドの接合方法を提供することである。
本発明のもう一つの目的はろう付けによる接合工程を簡略化可能なゴルフクラブヘッドの接合方法を提供することである。 A main object of the present invention is to provide a golf club head joining method capable of improving the joining quality by brazing.
Another object of the present invention is to provide a golf club head joining method capable of simplifying the joining process by brazing.

上述の目的を達成するために本発明によるゴルフクラブヘッドの接合方法は、金属材料から二つまたはそれ以上のユニットを製作し、ろう付けによりこれらのユニットを接合することである。その特徴は接合材料のろう付けの面に金属層が予め施され、金属層の材料が金、銀、白金、パラジウム、銅、ニッケル、コバルト、クロム、アルミニウム、モリブデン、ニオブ、チタン、鉛、スズ、亜鉛、カドミウム、またはその合金などのいずれか一つであり、金属層がメッキ、ろう付け、スプレー、溶融メッキ、物理または化学スッパタ沈積、化学メッキ、加圧成型などの方法により製作されることである。   In order to achieve the above object, a method for joining golf club heads according to the present invention is to manufacture two or more units from a metal material and join these units by brazing. The feature is that a metal layer is pre-applied to the brazing surface of the joining material, and the material of the metal layer is gold, silver, platinum, palladium, copper, nickel, cobalt, chromium, aluminum, molybdenum, niobium, titanium, lead, tin , Zinc, cadmium, or an alloy thereof, and the metal layer is manufactured by a method such as plating, brazing, spraying, hot dipping, physical or chemical sputtering, chemical plating, or pressure molding. It is.

これにより接合待ちの金属ユニットの接合面は金属層により酸化しないように保護されるため、ろう付けの際の潤湿性と接合品質とを向上させ、ろう付けの際に脆性生成などの有害反応が生じることを抑制し、延展性を向上させることが可能なだけでなく、ろう材と母材との反応により母材の成分と性能とを変化させ母材を破裂させることを防止することも可能である。したがってろう付け工程を簡略化し、ろう付けの品質を改善することが可能となる。   As a result, the joint surface of the metal unit waiting to be joined is protected from oxidation by the metal layer, thereby improving the wettability and joining quality during brazing, and causing adverse reactions such as brittleness during brazing. It is possible not only to suppress the occurrence and improve the spreadability, but also to prevent the base material from bursting by changing the composition and performance of the base material due to the reaction between the brazing material and the base material. It is. Therefore, the brazing process can be simplified and the quality of brazing can be improved.

以下、本発明の実施例を図面に基づいて説明する。
図１に示すように、本発明の第一実施例によるウッドクラブヘッド１０はヘッド本体１１、打球面ユニット１２、及び頂蓋１３から構成される。ヘッド本体１１はネック１４を有し、打球面ユニット１２はカップ状を呈し、頂蓋１３は超薄金属片から構成される。本実施例はヘッド本体１１及び頂蓋１３の二つのユニットに金属層１１１、１３１を別々に設け、打球面ユニット１２の接合部位の周縁に金属層１２１を設け、これらの金属層により隔離保護層を形成し、内層の金属を空気に接触させ酸化させることを防止し、続いてろう付けによりこれらのユニットを接合してヘッドを構成する。 Embodiments of the present invention will be described below with reference to the drawings.
As shown in FIG. 1, the wood club head 10 according to the first embodiment of the present invention includes a head body 11, a hitting surface unit 12, and a top lid 13. The head main body 11 has a neck 14, the ball striking face unit 12 has a cup shape, and the top cover 13 is made of an ultrathin metal piece. In this embodiment, the metal layers 111 and 131 are separately provided on the two units of the head main body 11 and the top lid 13, and the metal layer 121 is provided on the periphery of the joining portion of the ball striking surface unit 12. To prevent the inner layer metal from coming into contact with air and oxidizing, and then joining these units by brazing to form the head.

図２に示すように、ヘッド本体１１は接合部位に凹槽１１２を有し、打球面ユニット１２は接合部位に前記凹槽１１２に嵌まる突起状の嵌合部１２２を有し、凹槽１１２はろう付けのろう材が塗布され、ろう付けのろう材は真空オーブンの加熱を受けて接合層１５を形成する。
本実施例の長所は金属保護層を形成し、材料を用意する際に材料を待つ時間が比較的長いだけでなく、ろう付けによる接合強度、例えばステンレスとチタン合金が接合しにくいという問題を改善することを可能にすることである。またこれらのユニットに付着し易い金属材料を選び金属保護層を形成し、そののち金属保護層と結合し易いろう付けのろう材を用いてこれらのユニットを接合することも可能であるため、同様にろう付けによる接合強度を確実に高めることが可能となる。 As shown in FIG. 2, the head main body 11 has a concave tub 112 at the joint portion, and the ball striking surface unit 12 has a protruding fitting portion 122 that fits into the concave tub 112 at the joint portion. A brazing brazing material is applied, and the brazing brazing material is heated in a vacuum oven to form the bonding layer 15.
The advantage of this example is that a metal protective layer is formed, and not only the time to wait for the material when preparing the material is relatively long, but also the problem of the bonding strength by brazing, for example, the difficulty of joining stainless steel and titanium alloy is difficult It is possible to do. It is also possible to select a metal material that easily adheres to these units, form a metal protective layer, and then bond these units using a brazing brazing material that is easily bonded to the metal protective layer. It is possible to reliably increase the bonding strength by brazing.

図３に示すように本発明の第二実施例による鉄クラブヘッド２０は打球面ユニット２１、底部ユニット２２、及び背部ユニット２３から構成される。打球面ユニット２１は直接チタン合金から構成されるため金属層を設ける必要がなくなる。底部ユニット２２は耐磨耗性のある重りであり、かつ接合部位に金属層２２１を有する。背部ユニット２３はステンレスから構成され、かつその外部を被覆する金属層２３１を有する。
図４に示すように、打球面ユニット２１と底部ユニット２２との間はろう付けのろう材から形成される接合層２４により結合される。 As shown in FIG. 3, the iron club head 20 according to the second embodiment of the present invention includes a hitting surface unit 21, a bottom unit 22, and a back unit 23. Since the ball striking face unit 21 is directly made of a titanium alloy, it is not necessary to provide a metal layer. The bottom unit 22 is a wear-resistant weight, and has a metal layer 221 at the joint site. The back unit 23 is made of stainless steel and has a metal layer 231 that covers the outside.
As shown in FIG. 4, the ball striking face unit 21 and the bottom unit 22 are bonded to each other by a bonding layer 24 formed of a brazing brazing material.

上述の二つの実施例における金属保護層の形成方法は、ユニットの所定の位置にろう付けのろう材を塗布し、そののちユニットを加熱炉に入れて加熱し、ろう付けのろう材によりユニットの塗布面に金属層を形成することである。これにより接合待ちのユニットに金属層を与え、後続のろう付けによる接合作業をスムーズに実施することが可能である。
上述の二つの実施例はろう付けのろう材により金属保護層を形成する方法のみを挙げ、説明を加えるものであるが、本発明の精神に基づきメッキ、スプレー、溶融メッキ、物理または化学スッパタ沈積、化学メッキ、加圧成型などの方法により接合待ちのユニットの接合部位の一部分または全面に金属保護層を形成することも可能である。 In the above two embodiments, the metal protective layer is formed by applying a brazing brazing material to a predetermined position of the unit, and then heating the unit in a heating furnace and using the brazing brazing material. A metal layer is formed on the coated surface. As a result, it is possible to apply a metal layer to the unit waiting for joining and smoothly perform joining work by subsequent brazing.
The above two embodiments only give a description of the method of forming a metal protective layer by brazing brazing material, but in the spirit of the present invention, plating, spraying, hot dipping, physical or chemical sputter deposition. It is also possible to form a metal protective layer on a part or the entire surface of the joining portion of the unit waiting to be joined by a method such as chemical plating or pressure molding.
