Description

本発明は、ポリエチレン管等からなる配水管に分水栓の通水口と連通する貫通孔を効率的に穿孔することができ、かつ、穿孔部の切片を穿孔機内に収容して除去することができる樹脂管穿孔機に関するものである。   The present invention is capable of efficiently drilling a through hole communicating with a water faucet of a water faucet in a water distribution pipe made of a polyethylene pipe or the like, and allowing a section of the perforated part to be accommodated in a perforator and removed. The present invention relates to a resin pipe punching machine.

水道配水の配水本管には鋳鉄などの金属管が用いられてきたが、作業性や電気腐食などの問題から、近年、高密度ポリエチレン管等の樹脂管が用いられるようになり、樹脂管を水道管として使用する際に分岐管を取り付けるための分水栓を樹脂管に設定し、分水栓の通水口と連通する貫通孔を穿孔する必要がある。   Metal pipes such as cast iron have been used for water distribution mains, but due to problems such as workability and electrical corrosion, resin pipes such as high-density polyethylene pipes have recently been used. When used as a water pipe, it is necessary to set a water faucet for attaching a branch pipe to a resin pipe and to drill a through hole communicating with the water faucet of the water faucet.

従来、上記のような貫通孔を穿孔する樹脂管穿孔機として、当初は特許文献１に記載のように穿孔刃の再使用ができないもので切粉を排出する機構がなく、穿孔刃の再使用と切粉の排出の必要性から特許文献２に記載のように、中空パイプ状のホルソと、その外周に固着されるガイドパイプと、ホルソに連結されてホルソを回動駆動するシャンクとから成り、ホルソの内部に切刃側に開口する深穴を形成し、ホルソの開口側に形成した螺旋溝により切粉を深穴内に導入して収容するようにしたものが開発された。   Conventionally, as a resin pipe punching machine for punching through-holes as described above, the drilling blade cannot be reused as described in Patent Document 1, and there is no mechanism for discharging chips, and the drilling blade can be reused. Because of the necessity of discharging chips, it is composed of a hollow pipe-shaped horso, a guide pipe fixed to the outer periphery thereof, and a shank connected to the holso and rotationally driving the horso. A deep hole that opens to the cutting edge side is formed in the inside of the horso, and chips are introduced into the deep hole by a spiral groove formed on the opening side of the holso and accommodated.

しかし、特許文献２に記載のものも、ホルソから切粉を排出除去するためには、収容されている切粉の量なども確認できないまま、ホルソを中間ロッドから取外し、別部材を挿入して切粉を押出さなければならない問題があり、特許文献３に記載のように、先端部にカッターを設けたリードシャフトにより構成された穿孔体を、一端が分水栓の上部開口部取付け部、他端に雌ねじが形成された取付け本体の雌ねじとリードシャフトの雄ねじを螺合して軸方向に移動可能に取付け、リードシャフトを回動下降させて穿孔し、円筒状カッターの円筒内部に穿孔切片を保持し、穿孔機を分水栓から外した後にリードシャフトの貫通孔を通じて押し出し棒を挿入して穿孔切片を押し出し排出するように改良される。   However, in order to discharge and remove the chips from the horuso, the one described in Patent Document 2 also removes the horuso from the intermediate rod without inserting the amount of the contained chips and inserts another member. There is a problem that chips must be extruded, as described in Patent Document 3, a perforated body constituted by a lead shaft provided with a cutter at the tip part, one end of the upper opening attachment part of the water faucet, The internal thread of the mounting body with the internal thread formed on the other end and the external thread of the lead shaft are screwed together and mounted so as to be movable in the axial direction, the lead shaft is pivoted down and drilled, and a perforated section inside the cylinder of the cylindrical cutter , And after removing the drilling machine from the water tap, the pusher bar is inserted through the through hole of the lead shaft so that the punched section is pushed out and discharged.

更に、特許文献４記載のように、長さ方向に切割を有する円筒状のガイド部の先端に切削用のエッジを設けた刃物と、この刃物の外周をスライドするカバーを用い、カバーから露出したエッジ部分で樹脂管を切削し、切削に伴って発生する線状の切粉と切片はカバーとガイド部によって作られた空間に収容し、カバーをスライドさせれば切割を通してガイド部内部に収容されている切粉を視覚的に確認できるように改良されたものも存在する。
特開平０６−２８４８６号公報 特開平１１−２７７４９８号公報 特開２００３−２００３９２号公報 特開２００３−３４０６２５号公報 Further, as described in Patent Document 4, a blade with a cutting edge provided at the tip of a cylindrical guide portion having a cut in the length direction and a cover that slides on the outer periphery of the blade are exposed from the cover. The resin pipe is cut at the edge, and the linear chips and slices generated along with the cutting are stored in the space created by the cover and the guide. If the cover is slid, it is stored inside the guide through the slit. Some improvements have been made so that the chips can be visually confirmed.

しかしながら、上記の穿孔機は何れも切粉を排出除去するために、別部材を用いて特別の作業を行わなければならない問題があり、切粉の形態も特許文献３記載のもの以外は線状等で取扱い難いものとなっている。また、特許文献３記載のものは切粉の形態が円盤状で取扱い易いものとなっているが、穿孔機を分水栓から外した後に押し出し棒を用いなければ、切片を排出除去できない。   However, each of the above drilling machines has a problem that a special operation must be performed using a separate member in order to discharge and remove the chips, and the shape of the chips is also linear except that described in Patent Document 3. It is difficult to handle. Moreover, although the thing of patent document 3 is a thing which the shape of a chip | tip is a disk shape, and it is easy to handle, a section | seat cannot be discharged | emitted and removed unless an extruding bar is used after removing a punch from a water faucet.

また、樹脂配水管の穿孔は分水栓本体のバルブ機構を通して行わなければならないので、樹脂配水管に分水栓を取付け、分水栓の上部に穿孔機を固定する装着スタンドを着けて、それらの間隙通孔を通して穿孔刃を樹脂配水管の穿孔面に到達させ穿孔駆動を伝達させなければならない。そのため、シャフトへの穿孔刃の取付けに面倒な作業が必要となっている。   Also, since the resin water pipe must be drilled through the valve mechanism of the water faucet body, the water pipe is attached to the resin water pipe, and a mounting stand is attached to the top of the water cock to secure the drilling machine. The drilling blade must reach the drilling surface of the resin water distribution pipe through the gap through holes to transmit the drilling drive. Therefore, troublesome work is required for mounting the drilling blade to the shaft.

更に、穿孔機は樹脂配水管に取付けられた分水栓の上部に装着されるので、穿孔時には分水栓を開栓して分水栓中に穿孔刃を通過させるが、穿孔後、穿孔刃を抜去する際に所定位置を越えて上昇螺退させてしまうと、穿孔によりホルソ内に収容された配水管の穿孔切片が分水栓内に落下してしまう問題がある。   Furthermore, since the drilling machine is mounted on the upper part of the water faucet attached to the resin water distribution pipe, when drilling, the water faucet is opened and the drilling blade is passed through the water faucet. If the screw is lifted and retracted beyond a predetermined position when the pipe is removed, there is a problem that the perforated section of the water pipe accommodated in the horuso falls into the water faucet due to the perforation.

また、シャフトが分水栓閉栓可能位置以下であれば、当然のことながらシャフトが邪魔をして分水栓を閉栓することはできないので、適切な分水栓閉栓可能位置までシャフトが上昇螺退させて分水栓を閉栓しなければならないが、その位置をどのようにして確認するかの問題がある。   In addition, if the shaft is below the water faucet pluggable position, it is natural that the shaft will interfere and the water faucet cannot be closed. However, there is a problem of how to confirm the position.

本発明は上記した課題に対応しようとするものであり、穿孔刃を円筒状ホルソを主体とすることによって切粉の形態を円盤状の切片とすると共に、円筒の上部に穿孔刃を穿孔作動させるシャフトの先端雄ねじと螺合する雌ねじを設けた嵌合体を設け、シャフト先端の穿孔刃螺合雄ねじの上部に周回凹溝を設けて穿孔刃を組み付けたホルソベースと嵌合させ、穿孔刃に対してホルソベースの押出し片が昇降して穿孔刃内に収容した切片の排出除去作動と穿孔刃の抜去作動を連動させるようにした。   The present invention is intended to address the above-described problems, and by making the drilling blade mainly a cylindrical horuso, the shape of the chips is made into a disk-shaped piece, and the drilling blade is drilled at the upper part of the cylinder. A fitting body is provided with a female thread that is threadedly engaged with the male screw at the end of the shaft. The ejecting and removing operation of the slices housed in the drilling blade and the drilling operation of the drilling blade are linked with each other by moving the horuso base extruded piece up and down.

シャフト先端の穿孔刃螺合雄ねじの上部にシャフト先端に穿孔刃を係止する周回凹溝を設け、ホルソベース上部内壁に先端が内側に突出して前記周回凹溝に係合する止めねじを、穿孔刃嵌合体の上側部に設定して前記周回凹溝と止めねじ先端が嵌合してシャフト先端に穿孔刃を回動可能に係止するようにし、更に、前記周回凹溝の上部にストローク摺動部を設け、ホルソベース上部内壁にストローク摺動部の摺動面を圧締する弾性突条を設定してストローク摺動部を弾性突条が摺動可能に締着して穿孔駆動のためのシャフトとホルソベースの係合を安定したものとすると共に、ホルソベース上端の嵌合孔にシャフト先端部を嵌入すれば、嵌合孔内壁に弾性条体として設定されたＯリングとシャフト先端のストローク摺動部を圧締してホルソベースがシャフト先端に係止されるようにした。   A circular groove is provided on the top of the shaft at the top end of the threaded screw threaded with the perforated blade to lock the perforated blade. Set on the upper part of the fitting body so that the circumferential groove and the tip of the set screw are fitted, and the drilling blade is pivotally locked to the shaft tip, and further, the stroke slides on the upper part of the circumferential groove. A shaft for drilling drive by setting an elastic ridge that presses the sliding surface of the stroke sliding part on the inner wall of the upper part of the horuso base and fastening the elastic sliding slidable on the stroke sliding part. If the shaft tip is fitted into the fitting hole at the upper end of the hoso base, the O-ring set as an elastic strip on the inner wall of the fitting hole and the stroke sliding portion at the shaft tip Squeeze Vinegar was to be engaged with the shaft tip.

ホルソベースがシャフト先端に係止されることによって、穿孔刃の嵌合体両側間隙部にホルソベース押出し片が挿入されればホルソベースと穿孔刃を一体的に回動可能となり、シャフト先端の雄ねじと穿孔刃嵌合体の雌ねじを簡単に螺合できシャフト先端に穿孔刃を容易に着合できる。   By locking the holso base to the shaft tip, if the holso base extruding piece is inserted into the gap between both sides of the piercing blade fitting body, the holso base and the piercing blade can be rotated together. The combined female screw can be easily screwed together, and the drilling blade can be easily fitted to the tip of the shaft.

また、樹脂管穿孔後に、穿孔刃と共にシャフトを螺退させる際に、穿孔刃が分水栓の通水部を通過して所定位置まで上昇したときに、装着スタンド上面に位置するシャフトの部位に塗装等による表示をするようにして、分水栓の閉栓時期を確認できるようにした。   In addition, when the shaft is screwed together with the drilling blade after drilling the resin tube, when the drilling blade passes through the water passing portion of the water faucet and rises to a predetermined position, the shaft portion located on the top surface of the mounting stand It was made possible to check the closing time of the water faucet by displaying it by painting.

本発明は、穿孔刃を昇降作動するシャフトと穿孔刃にホルソベースを組み付けて係合させ、ホルソベースと穿孔刃を押出し片によって挿脱自在に嵌合させて穿孔刃に対してホルソベースの押出し片が昇降して穿孔刃内に収容した切片の排出除去作動と穿孔刃の抜去作動を連動させたので、穿孔切片の排出除去のために他の特別な機材や作業を必要としない効果がある。   In the present invention, the horso base is assembled and engaged with the shaft for moving the drilling blade up and down and the piercing blade, and the holso base and the piercing blade are detachably fitted by the extruding piece so that the pushing piece of the horso base is raised and lowered with respect to the piercing blade. Since the discharge removal operation of the section accommodated in the perforation blade and the extraction operation of the perforation blade are interlocked, there is an effect that no other special equipment or work is required for discharging and removing the perforation section.

また、シャフト先端の穿孔刃螺合雄ねじの上部に周回凹溝を設け、先端が内側に突出して前記周回凹溝と嵌合する止めねじを穿孔刃の上側部に設定してシャフト先端に穿孔刃を回動可能に係止できるようにし、更に、ホルソベース上部内壁にシャフトのストローク摺動部を圧締する弾性突条を設定すれば、シャフトにホルソベースをワンタッチで嵌入係合でき、穿孔刃の嵌合体両側間隙部にホルソベース押出し片が挿入されればホルソベースと穿孔刃を一体的に回動可能となり、シャフト先端の雄ねじと穿孔刃嵌合体の雌ねじを簡単に螺合できシャフト先端に穿孔刃を容易に着合できる。   Also, a circular groove is provided in the upper part of the threaded male screw threaded at the tip of the shaft, and a set screw that protrudes inward and engages with the circular groove is set on the upper part of the hole so that the hole is formed at the shaft tip. If an elastic ridge that presses the stroke sliding part of the shaft is set on the inner wall of the upper part of the holso base, the holso base can be fitted and engaged with the shaft with one touch. If a holso base extruding piece is inserted in the gap on both sides of the combined body, the holso base and the drilling blade can be rotated together, and the male screw on the shaft tip and the female screw on the drilling blade fitting can be easily screwed together, making the drilling blade easy on the shaft tip. Can be dressed.

樹脂管穿孔後に穿孔刃と共にシャフトを螺退させる際に、穿孔刃が分水栓の通水部を通過して所定位置まで上昇したときに、装着スタンド上面に位置するシャフトの部位に塗装等による表示が存在するので、シャフトが分水栓閉栓位置を越えて上昇螺退することによる事故を防止し、分水栓の閉栓時期を確認できる。   When the shaft is screwed together with the drilling blade after drilling the resin tube, when the drilling blade passes through the water passage of the water faucet and rises to the specified position, the shaft part located on the top surface of the mounting stand is coated with paint, etc. Since there is a display, it is possible to prevent accidents caused by the shaft being lifted and retracted beyond the water stopper closing position, and to confirm the closing timing of the water stopper.
