Description
【０００１】[0001]
本考案は、パイプ切断装置に関する。 The present invention relates to a pipe cutting device.
【０００２】[0002]
従来のパイプ切断装置は、パイプの切断予定箇所の前後いずれか一方を、平板 状のクランプにて挟着状に保持し、そのパイプを、切削液を流しつつ、帯のこに て切断するものであった。 A conventional pipe cutting device holds either one of the front and rear of the planned cutting point of the pipe in a clamped manner with a flat plate clamp, and cuts the pipe with a cutting fluid while cutting it with a band saw. Met.
【０００３】[0003]
しかし、上述のような従来のパイプ切断装置では、切削液と切粉の分離等をす る処理設備が必要となり、切断装置全体が大きくなると共に、切削液の漏れ等に より作業環境が悪くなるという問題があった。 However, the conventional pipe cutting device as described above requires a processing facility for separating cutting fluid and chips, etc., and the cutting device becomes large as a whole, and the working environment deteriorates due to leakage of cutting fluid. There was a problem.
【０００４】 また、平板状のクランプでは、パイプとの接点が少ないため、パイプに応力集 中が生じて変形することがあった。さらに、平板状のクランプでは、パイプのセ ッティングが困難であり、パイプ径に応じて、帯のこや、入側・出側の搬送コン ベア等を、シフトさせる必要があった。このため、切断に要する時間が極めて長 くなっていた。Further, since the flat plate-shaped clamp has few contact points with the pipe, stress concentration may occur in the pipe and the pipe may be deformed. Further, with a flat clamp, pipe setting is difficult, and it was necessary to shift the band saw and the transfer conveyors on the input and output sides according to the pipe diameter. Therefore, the time required for cutting was extremely long.
【０００５】 また、クランプは、パイプの切断予定箇所の前後いずれか一方のみを挟着状に 保持するため、切断直前にパイプが自重で折れ曲がり、切断端縁にバリが生じる という問題があった。Further, since the clamp holds only one of the front and rear of the planned cutting portion of the pipe in a sandwiched manner, there is a problem that the pipe is bent by its own weight immediately before the cutting and a burr is generated at the cutting edge.
【０００６】 そこで、本考案は、上述の問題を解決して、切削液を使用することなく切断で きるパイプ切断装置を提供することを目的とする。Therefore, an object of the present invention is to solve the above-mentioned problems and to provide a pipe cutting device capable of cutting without using a cutting fluid.
【０００７】 また、パイプの変形を防止できると共に、切断端縁にバリが生じないようにで き、かつ、パイプのセッティングの迅速化を図り得るパイプ切断装置を提供する ことを目的とする。Another object of the present invention is to provide a pipe cutting device capable of preventing deformation of the pipe, preventing burrs from being formed on the cutting edge, and speeding up setting of the pipe.
【０００８】 さらに、パイプを短寸に輪切りしても変形しないようにできるパイプ切断装置 を提供することを目的とする。Further, it is an object of the present invention to provide a pipe cutting device capable of preventing deformation even if the pipe is cut into short pieces.
【０００９】[0009]
上述の目的を達成するために本考案に係るパイプ切断装置は、被切断用パイプ を保持するパイプ保持手段と、このパイプ保持手段に対して回転カッター円板を 接近分離自在に送りを与える送り手段と、を備えると共に、該回転カッター円板 の外周縁に多数の凸歯を形成すると共に該凸歯に超硬チップを付設してなる無切 削液回転切断手段を、有するものである。 In order to achieve the above object, a pipe cutting device according to the present invention comprises a pipe holding means for holding a pipe to be cut, and a feeding means for feeding a rotary cutter disk to the pipe holding means so that the rotary cutter disc can be approached and separated from the pipe holding means. And a non-cutting liquid rotary cutting means in which a large number of convex teeth are formed on the outer peripheral edge of the rotary cutter disk and a cemented carbide tip is attached to the convex teeth.
【００１０】 また、本考案のパイプ切断装置は、被切断用パイプの切断予定箇所の前後を挟 着状に保持する一対の第１・第２クランプ機構を有すると共に、該第１・第２ク ランプ機構が、往復作動手段にて開閉する可動Ｖ溝付クランプ部材と、該可動Ｖ 溝付クランプ部材に対向状に配設される固定Ｖ溝付クランプ部材と、を備えてい る。Further, the pipe cutting device of the present invention has a pair of first and second clamp mechanisms for holding the front and rear of the planned cutting portion of the pipe to be cut in a clamped state, and further, the first and second clamp mechanisms are provided. The ramp mechanism includes a movable V-groove clamp member that is opened and closed by the reciprocating operation means, and a fixed V-groove clamp member that is arranged to face the movable V-groove clamp member.
【００１１】 さらに、一対の第１・第２クランプ機構の各々の可動Ｖ溝付クランプ部材を、 往復作動手段の共通移動部材に取付けて、２個の上記可動Ｖ溝付クランプ部材を 、一体状に開閉させるようにしたものである。Further, each movable V-groove clamp member of the pair of first and second clamp mechanisms is attached to the common moving member of the reciprocating operation means, and the two movable V-groove clamp members are integrally formed. It is designed to open and close.
【００１２】[0012]
回転カッター円板の凸歯の超硬チップにより、被切断用パイプの切断に於て、 切削液が不要となる。 The convex tooth carbide tip of the rotating cutter disc eliminates the need for cutting fluid when cutting the pipe to be cut.
【００１３】 また、第１・第２クランプ機構の可動Ｖ溝付クランプ部材と固定Ｖ溝付クラン プ部材にて、被切断用パイプを挟着状に保持するため、パイプに作用する保持力 が周方向の４箇所に分散する。さらに、パイプの切断予定箇所の前後を保持する ため、切断後でもパイプは動かず、切断端縁にバリが生じない。Further, since the pipe to be cut is held in a sandwiched state by the movable V-groove clamp member and the fixed V-groove clamp member of the first and second clamp mechanisms, the holding force acting on the pipe is Dispersed in 4 locations in the circumferential direction. Furthermore, since the pipe is held before and after the planned cutting point, the pipe does not move even after cutting, and burrs do not occur at the cutting edge.
【００１４】 さらに、共通移動部材に取付けられた２個の可動Ｖ溝付クランプ部材を一体状 に閉じれば、パイプの切断予定箇所の前後に保持力が略均等に配分される。Further, if the two movable V-groove clamp members attached to the common moving member are integrally closed, the holding force is distributed substantially evenly before and after the planned cutting position of the pipe.

【００２３】 送り手段４は、平面的に見て、第１・第２クランプ機構７，８とは逆の対角位 置に位置ずれして配設される第１・第２送り機構21, 22を有する。第１・第２送 り機構21, 22は、各々、基台枠５の天板部９上に固着されるガイド枠23と、その ガイド枠23に左右方向にスライド自在に取付けられるスライド部材24と、そのス ライド部材24に前後方向の軸心廻りに回転可能に取付けられる回転カッター円板 ３と、スライド部材24に付設されると共に回転カッター円板３に変速機構等を介 して回転を与えるモータ25と、本体26ａが基台枠５の天板部９の左右外側部に水 平状に取付けられると共にシリンダーロッド26ｂの先端がスライド部材24の外端 部に連結されてそのスライド部材24を左右に移動させる油圧シリンダー部材26と 、を備える。The feeding means 4 is arranged in a diagonal position opposite to the first and second clamping mechanisms 7 and 8 when seen in a plan view. Has 22. Each of the first and second feeding mechanisms 21 and 22 includes a guide frame 23 fixed to the top plate portion 9 of the base frame 5, and a slide member 24 that is slidably attached to the guide frame 23 in the left-right direction. And a rotary cutter disk 3 rotatably attached to the slide member 24 about an axis in the front-rear direction, and a rotary cutter disk 3 attached to the slide member 24 and rotated to the rotary cutter disk 3 via a speed change mechanism or the like.

【００２４】 第１送り機構21の回転カッター円板３と、第２送り機構22の回転カッター円板 ３は、平面的に見て左右方向に一直線上に配設される。The rotary cutter disk 3 of the first feeding mechanism 21 and the rotary cutter disk 3 of the second feeding mechanism 22 are arranged in a straight line in the left-right direction when viewed two-dimensionally.
【００２５】 また、図４に示すように、回転カッター円板３は、外周縁に多数の凸歯27…を 有する。そして、その凸歯27に、超硬チップ28が付設される。つまり、この装置 は、回転カッター円板３の外周縁に多数の凸歯27…を形成すると共に該凸歯27に 超硬チップ28を付設してなる無切削液回転切断手段29を、有する。Further, as shown in FIG. 4, the rotary cutter disk 3 has a large number of convex teeth 27 ... Then, the carbide teeth 28 are attached to the convex teeth 27. That is, this apparatus has a non-cutting fluid rotary cutting means 29 in which a large number of convex teeth 27 are formed on the outer peripheral edge of the rotary cutter disk 3 and a carbide tip 28 is attached to the convex teeth 27.
【００２６】 これにより、切削液を使用することなくパイプ１を切断することができ、従来 必要であった切削液と切粉の分離等の処理を行う設備を省略することができる。 従って、この装置のコンパクト化と、作業環境の改善を図ることができる。As a result, the pipe 1 can be cut without using a cutting fluid, and equipment conventionally required for processing such as separation of cutting fluid and cutting chips can be omitted. Therefore, the device can be made compact and the working environment can be improved.
【００２７】 しかして、（図１と図２と図３にもどって）上述のように構成したこのパイプ 切断装置を使用するには、先ず、第１・第２クランプ機構７，８の可動Ｖ溝付ク ランプ部材14, 14を上昇させて開状態とし、その可動Ｖ溝付クランプ部材14, 14 と、その下方の固定Ｖ溝付クランプ部材15, 15との間に、前方から後方へと被切 断用パイプ１を挿入する。そして、パイプ１の切断予定箇所６を、前後の固定Ｖ 溝付クランプ部材15, 15の間の隙間部Ｓに一致させてパイプ１をセッティングす る。In order to use this pipe cutting device configured as described above (returning to FIG. 1, FIG. 2, and FIG. 3), first, the movable V of the first and second clamp mechanisms 7 and 8 should be used. The grooved crumpling members 14, 14 are raised to an open state, and between the movable V-grooved clamp members 14, 14 and the fixed V-grooved clamp members 15, 15 therebelow, from front to back. Insert the pipe 1 to be cut. Then, the pipe 1 is set by aligning the planned cutting point 6 of the pipe 1 with the gap S between the front and rear fixed V grooved clamp members 15, 15.
【００２８】 このとき、固定Ｖ溝付クランプ部材15, 15のＶ溝19, 19上にパイプ１が嵌まる ため、パイプ１のセッティングを迅速かつ容易に行うことができる。従って、切 断時間の短縮化を図り得る。At this time, since the pipe 1 is fitted on the V grooves 19, 19 of the fixed V-groove clamp members 15, 15, the pipe 1 can be set quickly and easily. Therefore, the cutting time can be shortened.
【００２９】 その後、図５に略示するように、第１・第２クランプ機構７，８の可動Ｖ溝付 クランプ部材14, 14を下降させて閉状態とする。これにより、パイプ１は、上下 のＶ溝18, 19の間に挟着状に固定され、パイプ１の周壁には、周方向の４箇所か ら軸心へ向く保持力Ｆが作用する。従って、従来の平板状のクランプ部材にて挟 着状に固定する場合に比して、応力の集中を緩和することができ、パイプ１（の 切断後）の変形を防止できる。Thereafter, as schematically shown in FIG. 5, the movable V-groove clamp members 14 and 14 of the first and second clamp mechanisms 7 and 8 are lowered to be in a closed state. As a result, the pipe 1 is fixed so as to be sandwiched between the upper and lower V-grooves 18, 19, and a holding force F is applied to the peripheral wall of the pipe 1 from four circumferential positions toward the axial center. Therefore, the stress concentration can be relaxed and deformation of the pipe 1 (after cutting) can be prevented as compared with the case where the plate-shaped clamp member is fixed in a sandwiched manner.
【００３０】 さらにその後、図６に略示するように、送り手段４の第１・第２送り機構21, 22を交互に作動させて、左右の回転カッター円板３，３にて、パイプ１の略半分 ずつを切断する。このように切断することにより、回転カッター円板３，３の半 径Ｒの略２倍の外径寸法を有する被切断用パイプ１を切断することができる。After that, as schematically shown in FIG. 6, the first and second feeding mechanisms 21 and 22 of the feeding means 4 are alternately operated, and the left and right rotary cutter disks 3 and 3 are used to make the pipe 1 Cut approximately half of each. By cutting in this way, it is possible to cut the pipe 1 to be cut having an outer diameter dimension approximately twice the half diameter R of the rotary cutter disks 3, 3.
【００３１】 また、図２と図３からも明らかな如く、切断予定箇所６の前後が第１・第２ク ランプ機構７，８の可動Ｖ溝付クランプ部材14, 14と固定Ｖ溝付クランプ部材15 , 15にて固定されるため、切断終了直前に、パイプ１が自重で折れ曲がらないよ うに保持することができる。従って、切断端縁にバリが生じないようにでき、切 断後のバリ取りが不要となる。Further, as is apparent from FIGS. 2 and 3, the movable V-groove clamp members 14 and 14 of the first and second clamp mechanisms 7 and 8 and the fixed V-groove clamp are located before and after the planned cutting point 6. Since it is fixed by the members 15, 15, the pipe 1 can be held so as not to bend due to its own weight immediately before the end of cutting. Therefore, it is possible to prevent burrs from being generated at the cutting edge, and it is not necessary to remove burrs after cutting.
【００３２】 上述のようにしてパイプ１の切断が終了した後は、第１・第２クランプ機構７ ，８の可動Ｖ溝付クランプ部材14, 14を上昇させて開状態とし、切断されたパイ プ１を取り出せばよい。After the cutting of the pipe 1 is completed as described above, the movable V-grooved clamp members 14, 14 of the first and second clamp mechanisms 7, 8 are lifted to the open state, and the cut pipe is cut. All you have to do is to take out poop 1.
【００３３】 なお、図１と図２に示した送り手段４の第１・第２送り機構21, 22のシリンダ ー部材26のかわりに、スクリューシャフトとサーボモータを用いるも自由である 。即ち、その場合、ガイド枠23に沿ってスクリューシャフトを回転自在に配設す ると共に、それに変速機構等を介してサーボモータを連動連結し、かつ、スライ ド部材24に雌ネジ部を設けて、その雌ネジ部にスクリューシャフトを螺入させれ ばよい。A screw shaft and a servomotor may be used in place of the cylinder member 26 of the first and second feeding mechanisms 21 and 22 of the feeding means 4 shown in FIGS. 1 and 2. That is, in that case, a screw shaft is rotatably arranged along the guide frame 23, a servo motor is interlockedly connected thereto via a speed change mechanism, and a female screw portion is provided on the sliding member 24. , The screw shaft may be screwed into the female screw part.
【００３４】 次に、図７は、他の実施例の要部を示し、この場合、往復作動手段33は、基台 枠５の天板部９の下方に設けられた取付部32に本体11ａが固着される１個の油圧 シリンダー11と、そのシリンダー11にて上下に移動させられる共通移動部材31と 、からなる。また、共通移動部材31は、油圧シリンダー11のシリンダーロッド12 の先端に固着された共通支持板34と、その共通支持板34に下端部が固着されると 共に上端部に可動Ｖ溝付クランプ部材14, 14が取付けられる２本の昇降杆13, 13 と、から構成される。Next, FIG. 7 shows a main part of another embodiment. In this case, the reciprocating operation means 33 is mounted on the mounting part 32 provided below the top plate part 9 of the base frame 5 and the main body 11a. Is composed of one hydraulic cylinder 11 to which is fixed, and a common moving member 31 which is vertically moved by the cylinder 11. The common moving member 31 includes a common support plate 34 fixed to the tip of the cylinder rod 12 of the hydraulic cylinder 11, a lower end portion fixed to the common support plate 34, and a movable V groove clamp member at the upper end portion. It consists of two lifting rods 13, 13 to which 14, 14 are attached.
【００３５】 つまり、この装置は、第１・第２クランプ機構７，８の各々の可動Ｖ溝付クラ ンプ部材14, 14を、往復作動手段33の共通移動部材31に取付けて、２個の可動Ｖ 溝付クランプ部材14, 14を、一体状に開閉させるようにしたものである。That is, in this device, the movable V-grooved clamp members 14 and 14 of the first and second clamp mechanisms 7 and 8 are attached to the common moving member 31 of the reciprocating operation means 33 so that two clamp members are provided. The movable V-groove clamp members 14, 14 are integrally opened and closed.
【００３６】 しかして、図８に示すように、２個の可動Ｖ溝付クランプ部材14, 14は一体状 に閉じるため、パイプ１の一端部を短寸に切断した場合でも、その強度が小なる 短寸パイプ１ａのみに保持力Ｆ1 ，Ｆ1 ′が集中しないようにできる。また、長 寸パイプ１ｂは、短寸パイプ１ａに比して強度が大であるため、変形は生じない 。従って、２個の可動Ｖ溝付クランプ部材14, 14はそれ以上下降することはなく 、これにより短寸パイプ１ａが変形するのを防止できる。However, as shown in FIG. 8, since the two movable V-groove clamp members 14, 14 are integrally closed, even if one end of the pipe 1 is cut into a short length, its strength is small. The holding forces F 1 and F 1 ′ can be prevented from concentrating only on the short pipe 1a. Further, since the long pipe 1b has a higher strength than the short pipe 1a, no deformation occurs. Therefore, the two movable V-groove clamp members 14 and 14 do not move down any more, which prevents the short pipe 1a from being deformed.
【００３７】 次に、図９と図10と図11は、別の実施例を示し、この場合、送り手段４の第１ ・第２送り機構21, 22は、各々、基台枠５の天板部９上に枢支部材50を介して前 後方向の軸心廻りに揺動自在に枢着される左右方向の揺動枠35と、その揺動枠35 の内端部に前後方向の軸心廻りに回転可能に取付けられる回転カッター円板３と 、揺動枠35の中間部に付設されるモータ25と、モータ25とカッター円板３の間に 介装されてモータ25の回転力を回転カッター円板３に伝えるベルト41とプーリー 42, 42と変速器43とからなる連動連結手段36と、基台枠５の左右側面に本体26ａ が鉛直状乃至傾斜状に揺動自在として枢着されると共にシリンダーロッド26ｂの 先端が揺動枠35の外端部に枢結されるシリンダー部材26と、を備える。Next, FIG. 9, FIG. 10 and FIG. 11 show another embodiment. In this case, the first and second feeding mechanisms 21 and 22 of the feeding means 4 are respectively the top of the base frame 5. A swing frame 35 in the left-right direction pivotally mounted on the plate portion 9 via a pivot member 50 so as to be swingable around an axis in the front-rear direction, and an inner end portion of the swing frame 35 in the front-back direction. A rotary cutter disk 3 that is rotatably mounted around an axis, a motor 25 attached to the middle portion of the swing frame 35, and a rotational force of the motor 25 that is interposed between the motor 25 and the cutter disk 3. To the rotary cutter disk 3, an interlocking connecting means 36 consisting of a belt 41, pulleys 42, 42 and a transmission 43, and a main body 26a on the left and right side surfaces of the base frame 5 so as to be swingable vertically or inclined. The cylinder member 26 is attached and the tip of the cylinder rod 26b is pivotally connected to the outer end of the swing frame 35.
【００３８】 また、揺動枠35の先端部には、回転カッター円板３を覆う安全用のカバー部材 37が取付けられる。A safety cover member 37 that covers the rotary cutter disk 3 is attached to the tip of the swing frame 35.
【００３９】 さらに、基台枠５には、切粉排出手段38が設けられる。即ち、切粉排出手段38 は、基台枠５の上面側に於て、回転カッター円板３，３の真下からその中間部に わたって上方に開口すると共に下方にも開口する漏斗部材39と、基台枠５内にて 漏斗部材39の下方開口部の真下に水平に配設されると共に一端が基台枠５の外側 部に突出するコンベア部材40と、を備える。Further, the base frame 5 is provided with a chip discharging means 38. That is, the chip discharging means 38 is provided with a funnel member 39 which is open on the upper surface side of the base frame 5 from directly below the rotary cutter disks 3 and 3 to an intermediate portion thereof and also downward. A conveyor member 40 is horizontally disposed in the base frame 5 directly below the lower opening of the funnel member 39 and has one end protruding to the outside of the base frame 5.
【００４０】 しかして、この装置では、第１・第２送り機構21, 22のシリンダー部材26, 26 を交互に作動させて切断を行う。即ち、一方のシリンダー部材26のシリンダーロ ッド26を伸ばすと、揺動枠35は外端部が上昇する方向に揺動する。Therefore, in this apparatus, the cylinder members 26, 26 of the first and second feeding mechanisms 21, 22 are alternately operated to perform cutting. That is, when the cylinder rod 26 of the one cylinder member 26 is extended, the swing frame 35 swings in the direction in which the outer end portion rises.
【００４１】 これにより、揺動枠35の内端部が下降方向へ揺動して、一方の回転カッター円 板３にて、第１・第２クランプ機構７，８にてクランプ固定された被接続パイプ １の横断面に於ける半分以上が切断される。その後、上記と同様にして他方の回 転カッター円板３にて被接続パイプ１の反対側を切断すれば、パイプ１を完全に 切断できる。As a result, the inner end of the swing frame 35 swings in the descending direction, and the rotating cutter disk 3 on one side clamps the object to be clamped and fixed by the first and second clamp mechanisms 7 and 8. More than half of the cross section of the connecting pipe 1 is cut. After that, if the other side of the pipe 1 to be connected is cut by the other rotary cutter disk 3 in the same manner as described above, the pipe 1 can be completely cut.
【００４２】 また、切断により生じる切粉は、切粉排出手段38の漏斗部材39内を通り、コン ベア部材40上に落ちる。そして、その切粉は、コンベア部材40にて基台枠５の外 部に排出され、図示省略の切粉収容箱内に収納される。The chips generated by the cutting pass through the funnel member 39 of the chip discharging means 38 and fall on the conveyor member 40. Then, the chips are discharged to the outside of the base frame 5 by the conveyor member 40 and stored in a chip storage box (not shown).
【００４３】 上述のように、この装置によれば、切粉を排出できるため、作業環境を一層改 善できると共に、装置の故障を防止できる。As described above, according to this device, since the chips can be discharged, the working environment can be further improved and the device failure can be prevented.

【００４５】 請求項１記載のパイプ切断装置によれば、切削液を使用することなく被切断用 パイプ１を切断でき、従来必要であった切削液と切粉の分離等の処理を行う設備 を省略することができる。従って、装置全体のコンパクト化と、作業環境の改善 を図ることができる。According to the pipe cutting device of the first aspect, it is possible to cut the pipe 1 to be cut without using a cutting liquid, and to install the equipment required for the conventional processing such as separation of cutting liquid and cutting chips. It can be omitted. Therefore, the entire apparatus can be made compact and the working environment can be improved.
【００４６】 請求項２記載のパイプ切断装置によれば、（第１・第２クランプ機構７，８が パイプ１の切断予定箇所６の前後を挟着状に保持するため）被切断用パイプ１の 切断端縁に、バリが生じるのを防止でき、切断後のバリ取り加工が不要となる。 また、（可動Ｖ溝付クランプ部材14と固定Ｖ溝付クランプ部材15により）挟着状 に固定保持したパイプ１の変形を防止できる。特に、切断後に輪切り状となる短 い切断寸法のワークの変形防止に有効である。かつ、パイプ１の第１・第２クラ ンプ機構７，８へのセッティングを容易かつ迅速に行うことができ、切断時間を 短縮できる。According to the pipe cutting device of the second aspect, the pipe 1 to be cut (because the first and second clamp mechanisms 7 and 8 hold the front and rear of the planned cutting portion 6 of the pipe 1 in a sandwiched state). It is possible to prevent burrs from being generated at the cutting edge of, and there is no need for deburring after cutting. Further, it is possible to prevent the deformation of the pipe 1 which is fixedly held in a sandwiched state (by the movable V-groove clamp member 14 and the fixed V-groove clamp member 15). In particular, it is effective for preventing deformation of a work piece having a short cutting size that becomes a sliced shape after cutting. In addition, the pipe 1 can be easily and quickly set on the first and second clamp mechanisms 7 and 8, and the cutting time can be shortened.
【００４７】 また、請求項３記載のパイプ切断装置では、パイプ１を短寸に輪切りした場合 でも、それにより生じる強度が小なる短寸パイプ１ａが、パイプ保持手段２の保 持力により変形しないようにできる。Further, in the pipe cutting device according to the third aspect, even when the pipe 1 is cut into short pieces, the short pipe 1 a having a small strength generated by the cutting is not deformed by the holding force of the pipe holding means 2.
