Description

【0001】
【発明の属する技術分野】
本発明は、例えば釘打機に使用される釘送り機構に関するもので、打ち込み対象の釘を連結釘から分離させることで、先端部の断面形状が三日月あるいは半月形状となる異形状ブレードを丸形形状とすることが可能となり、これよりブレードの径を任意に設定することで、応力緩和によりブレードの耐摩耗性、耐チッピング性の向上を図るようにしたものである。
【0002】
【従来の技術】
図13は現行釘送り機構の一例を示す一部断面図である。現行釘送り機構を有する釘打機1aは、図14に示すような連結釘3aの釘4aの頭部がお互いに重なり合っている場合には、ブレード13aの形状は後続の釘3aの頭部を打撃しないように三日月形状にする必要がある。この場合、ブレード13aの形状は複雑形状となるため製造コストが高くなり、また、ブレード13aの面積は丸形形状ブレードに比べて小さくなるため疲労寿命が低下する問題があった。
【0003】
図15,図17に現行釘送り機構の釘打ち込み時、釘打ち込み後の動作状況を示す一部断面図を示す。ブレード13aは圧縮空気14aにより高速で移動し、ノーズ2a内部に装填された釘4aを打撃して前方に押し出し、被打込材12aに釘4aを打ち込むことができる。打ち込み終了後、ブレード13aは圧縮空気15aがシリンダ16aに充填されることで元の位置に戻ることができる。この時、ブレード13aが元に戻ることに連動して釘送りガイド7aが連結釘3aをノーズ2aに装填することにより次の釘を連続して打ち込むことができる。
【0004】
上記した釘の打ち込み動作中において、ブレード13aの先端外周すなわちエッジ部付近では局部的に高い引張応力が生じるため、エッジ部のチッピングや変形が発生してしまう。また、釘4aや被打込材12aと直接接触する先端面は摩耗が避けられない。このエッジ部のチッピングや変形及び先端面の摩耗等の問題を解消するために、ハイス材を先端部分に摩擦圧接により接合したハイスブレードや、特開平1−87164号に開示されているような超硬材を先端部分に摩擦圧接により接合した超硬ブレードが提案されており、ブレード先端部の耐摩耗性の向上を図っている。
【0005】
【発明が解決しようとする課題】
ブレード先端部の耐摩耗性を向上させるため前記ハイスブレードや超硬ブレードは有効である。しかしながら、ハイスブレードはハイス材の最適熱処理条件がブレード母材部と異なることから、母材部に最適熱処理を施すことができないという問題があり、母材部の強度を向上させることが困難であった。
【0006】
一方、超硬ブレードは、接合強度こそ低いものの、耐摩耗性に優れた材料であるためブレード先端部に適用すれば、先端部の寿命向上を図ることが可能となる。また、超硬材は熱処理温度900℃程度であれば、その特性が変動することがないため、母材部への最適熱処理が可能になる利点がある。しかしながら、接合時に発生した超硬材と鋼材の混ざり合ったバリの除去行程にコストがかかるという問題があり、特に異形状ブレードに対しては低価格で製品へ適用が困難であった。
【0007】
本発明の目的は、上記した従来技術の材料変更だけでは困難であるブレードの寿命向上及び低価格化を図るため、ブレードの断面積を円形状とし、かつ寸法の制限を受けずに設定することが可能となるブレードを使用できる打込機用釘送り機構を提供することである。
【0008】
【課題を解決するための手段】
上記目的は、装填された連結釘をブレードにより、被打込材に打ち込む打込機において、連結釘に連結された釘を連結材から分離する手段としてプッシュレバーと連動して移動する切断機具を用いて分離し、分離後、ノーズ部の所定打ち込み位置に釘送りガイドにより移動させ、所定打ち込み位置に分離した釘を永久磁石あるいは電磁石を用いて固定後、前記ブレードにより打ち込むことを特徴とする打込機用釘送り機構とすることにより達成される。
【0009】
【発明の実施の形態】
以下実施形態を示した図面を参照して本発明を説明する。図1は本発明釘送り機構の実施形態を示す一部断面図、図2は図1のA1部の抽出図とその左図である。本発明釘送り機構を有する釘打機1は、ノーズ2、連結釘3の釘4と連結材5を切断した分離した釘6をノーズ2まで送り出す釘送りガイド7、安全装置であるプッシュレバー8とプッシュレバー9、プッシュレバー8と連動して連結材5を切断するプッシュレバー8に固定された押し付け部10aとノーズ2に取り付けてある切断部10b、スプリング10c、止め金10dからなる切断機具10、分離した釘6を吸着、固定するノーズ2の内周面に装着され、ノーズ2と同内径を有する半円リング状の永久磁石11、分離した釘6を被打込材12に打ち込むブレード13、圧縮空気14と圧縮空気15によりブレード13が往復運動するシリンダ16、ブレード13が分離した釘6を打撃した後に接触するバンパ17、ピストンの移動により釘送りガイド7を移動させる圧縮空気18、釘固定ガイド19、釘送りガイド7を元の位置に戻すためのスプリング20から構成されている。
【0010】
本発明釘送り機構を有する釘打機1では、図1のように最初に連結釘3をセットする。これは、最初に連結釘3をブレード13が釘4を打撃する位置に固定してしまうと次に打ち込み対象となる釘4の頭部を打撃してしまうという問題を解消するためである。従って、本発明釘送り機構を有する釘打機1では、連結釘3を装着後に、ブレード13の釘4を打たずに空打ち動作を一度行う。
【0011】
図3は本発明釘送り機構の空打ち状態でブレード13が移動した時を示す一部断面図、図4は図3のA2部の抽出図とその左図である。
トリガの安全装置であるプッシュレバー8とプッシュレバー9が移動することにより、プッシュレバー8に固定された押し付け部10aがノーズ2に取り付けてある切断部10bを押し込み、連結釘3の釘4と連結材5を切断する。この時、圧縮空気14がシリンダ16内部に充填し、トリガを引くことでブレード13が高速で被打込材12を打撃し、また、圧縮空気18により釘送りガイド7は、連結釘3と分離した釘6をその場に残した状態で下方へ移動することになる。
【0012】
図5は本発明釘送り機構のブレード13が元の位置に移動した時を示す一部断面図、図6は図5のA3部の抽出図とその左図である。
ブレード13が被打込材12を打撃後、シリンダ16とバンパ17の内側に圧縮空気15が充填されることで、ブレード13は元の位置に移動する。この時、プッシュレバー8とプッシュレバー9が元に位置に戻り、これに連動して、切断部10bもまたスプリング10cにより元の位置に戻る。また、釘送りガイド7は、圧縮空気18が排気されることで、スプリング20により連結釘3と分離した釘6を上方へ押し上げることができる。
【0013】
図7は本発明釘送り機構の分離した釘6が打ち込み位置にセットされた状態を示す一部断面図、図8は図7のA4部の抽出図とその左図である。
上記動作により分離、移動した釘6は、永久磁石11の磁力によりノーズ内周部に吸引固定され、釘の打ち込みが可能な状態となる。
【0014】
図9,図11は、本発明釘送り機構の分離した釘6が打ち込まれた状態を示す一部断面図であり、図10、図12は図9、図11のA5、6部の抽出図とその左図である。
【0015】
図7に示す位置に分離した釘6が装填された後、図1、図3、図5と同等の動作を行うことで図9、図11に示すように被打込材12に分離した釘6を打ち込むことが可能となる。ここで、分離した釘6は、ノーズ2と釘固定ガイド18により脱落、落下しないでノーズ2の打ち込み対象となる釘の設置部まで運ばれ、2本目の釘の打ち込み時には、打ち込み対象となる釘は、既に分離されていることになるため、連続打ちに対しても支障がない。なお、この切断機具10は、プッシュレバー8と連動させて稼働させれば、動作上、問題がないので切断機具10の切断部10bをプッシュレバー8に直接固定させても問題はない。
【0016】
本発明釘送り機構を有する釘打機1では、場合によって分離した釘6は図8のように傾いた状態で吸引固定されることもあるが、ノーズ2内部の範囲で傾く分には傾き角はわずかであり、すなわち問題は生じない。
【0017】
図2に示した磁石11は、ノーズ2の内周に中空円筒形状としてノーズ2の内周径と同等の寸法で取り付けてあるが、ブレード13が移動する時磁石11が直接打撃されず、かつ、分離した釘6を吸引固定できる形状であれば図2の形状としなくても問題はない。また、磁石についても永久磁石以外として電磁石等の適用も可能である。
【0018】
【発明の効果】
以上のように本発明によれば、如何なる連結釘を使用した場合においてもブレード形状を任意に設定することが可能となり、高強度、耐摩耗性に優れたブレードを製作・提供できるようになる。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a nail feeding mechanism used for a nailing machine, for example, by separating a nail to be driven from a connecting nail, thereby forming a round blade having a crescent or half-moon cross section at the tip. This makes it possible to improve the wear resistance and chipping resistance of the blade by relaxing the stress by arbitrarily setting the diameter of the blade.
[0002]
[Prior art]
FIG. 13 is a partial cross-sectional view showing an example of the current nail feeding mechanism. In the nailing machine 1a having the current nail feeding mechanism, when the heads of the nails 4a of the connecting nails 3a overlap each other as shown in FIG. 14, the shape of the blade 13a changes the head of the subsequent nail 3a. It is necessary to make a crescent shape so as not to hit. In this case, the blade 13a has a complicated shape, so that the manufacturing cost is high. Further, the area of the blade 13a is smaller than that of the round blade, so that the fatigue life is reduced.
[0003]
FIGS. 15 and 17 are partial cross-sectional views showing the operation of the current nail feed mechanism at the time of nail driving and after nail driving. The blade 13a is moved at a high speed by the compressed air 14a, hits the nail 4a loaded in the nose 2a, pushes it forward, and drives the nail 4a into the material 12a. After the driving is completed, the blade 13a can return to the original position by filling the cylinder 16a with the compressed air 15a. At this time, the nail feed guide 7a loads the connecting nail 3a into the nose 2a in conjunction with the return of the blade 13a, whereby the next nail can be driven continuously.
[0004]
During the nail driving operation described above, a high tensile stress is locally generated on the outer periphery of the tip of the blade 13a, that is, near the edge portion, so that chipping or deformation of the edge portion occurs. In addition, abrasion is inevitable at the distal end surface which comes into direct contact with the nail 4a and the driven member 12a. In order to solve the problems such as chipping and deformation of the edge portion and wear of the front end surface, a high speed steel blade in which a high speed material is joined to the front end portion by friction welding, or a super high speed blade disclosed in Japanese Patent Application Laid-Open No. 1-87164. A cemented carbide blade in which a hard material is joined to a tip portion by friction welding has been proposed, and the wear resistance of the tip portion of the blade has been improved.
[0005]
[Problems to be solved by the invention]
The high-speed blade and the super hard blade are effective for improving the wear resistance of the blade tip. However, the HSS blade has a problem that the optimum heat treatment condition for the HSS material is different from that of the blade base material portion, and thus the base material portion cannot be subjected to the optimum heat treatment, and it is difficult to improve the strength of the base material portion. Was.
[0006]
On the other hand, the cemented carbide blade is a material having a low joining strength, but excellent in abrasion resistance. Therefore, if it is applied to the tip of the blade, the life of the tip can be improved. Further, if the heat treatment temperature is about 900 ° C., the characteristics of the cemented carbide material do not fluctuate, so that there is an advantage that the optimal heat treatment of the base material can be performed. However, there is a problem in that a cost is required for a process of removing burrs in which a cemented carbide material and a steel material generated at the time of joining are mixed. In particular, it is difficult to apply a deformed blade to a product at a low price.
[0007]
An object of the present invention is to set the cross-sectional area of the blade to a circular shape and to be set without any size restrictions in order to improve the service life and reduce the cost of the blade, which is difficult only by changing the material of the above-described conventional technology. It is an object of the present invention to provide a nail feed mechanism for a driving machine, which can use a blade capable of performing the above.
[0008]
[Means for Solving the Problems]
The above object is to provide a driving machine for driving a loaded connecting nail by a blade into a material to be driven, and a cutting tool which moves in conjunction with a push lever as a means for separating a nail connected to the connecting nail from the connecting material. The nail is then moved to a predetermined driving position of the nose portion by a nail feeding guide, the nail separated at the predetermined driving position is fixed using a permanent magnet or an electromagnet, and then driven by the blade. This can be achieved by using a nail feed mechanism for a nailing machine.
[0009]
