従来より、特許文献１に示すように、パイプを曲げ型と締め型とにより挟持して、締め型を曲げ型の廻りに公転させて曲げ加工を行なう曲げ加工装置が知られている。パイプは曲げ加工した後、例えば、流体の配管として用いられる場合、パイプの両端に継手が装着される。この継手を装着するために、パイプに端末加工が施される場合がある。あるいは、構造部品として用いられる場合、他の部品と接続するために、パイプに端末加工が施される場合がある。
特公平６−３６９４５号公報 Conventionally, as shown in Patent Document 1, a bending apparatus is known in which a pipe is sandwiched between a bending mold and a clamping mold, and the clamping mold is revolved around the bending mold to perform bending. After the pipe is bent, for example, when it is used as fluid piping, joints are attached to both ends of the pipe. In order to mount this joint, the pipe may be subjected to terminal processing. Alternatively, when used as a structural component, the pipe may be subjected to terminal processing in order to connect with other components.
Japanese Patent Publication No. 6-36945

しかしながら、こうした従来のものでは、端末加工を施す場合、曲げ加工する前にパイプに端末加工を施すか、あるいは、曲げ加工した後にパイプに端末加工を施すが、曲げ加工装置とは別の端末加工機にパイプを装着して、端末加工を施していたので、それぞれの装置が必要であると共に、加工手順も煩雑であるという問題があった。   However, in such a conventional one, when the end processing is performed, the end processing is performed on the pipe before bending, or the end processing is performed on the pipe after bending, but the end processing is different from the bending processing apparatus. Since pipes were attached to the machine and the terminal processing was performed, there was a problem that each apparatus was necessary and the processing procedure was complicated.

本発明の課題は、パイプの曲げ加工を行なうと共に、端末加工をも簡単に行うことができる曲げ加工装置を提供することにある。   An object of the present invention is to provide a bending apparatus capable of bending a pipe and easily performing terminal processing.

本発明の曲げ加工装置は、パイプの曲げ加工を行なうと共に、端末加工をも簡単に行うことができるという効果を奏する。   The bending apparatus of the present invention produces an effect that the pipe can be bent and the terminal processing can be easily performed.

以下本発明を実施するための最良の形態を図面に基づいて詳細に説明する。
図１に示すように、１は曲げ機構で、曲げ機構１は、長尺状のパイプ２の曲げ半径に応じて形成された曲げ型４を備え、曲げ型４の外周にはパイプ２の直径に応じた溝６が形成されている。曲げ型４は曲げアーム８と共に回転可能に支承されており、曲げアーム８は第１シリンダ１０により回転駆動されるように取り付けられている。曲げ型４は、図１では１つの溝６を有するものを示しているが、曲げ型４は、パイプ２の曲げ半径に応じた複数の溝６が積層されたものでもよい。 The best mode for carrying out the present invention will be described below in detail with reference to the drawings.
As shown in FIG. 1, reference numeral 1 denotes a bending mechanism. The bending mechanism 1 includes a bending die 4 formed according to the bending radius of a long pipe 2, and the diameter of the pipe 2 is provided on the outer periphery of the bending die 4. A groove 6 corresponding to the above is formed. The bending die 4 is rotatably supported together with the bending arm 8, and the bending arm 8 is attached so as to be rotationally driven by the first cylinder 10. Although the bending die 4 has one groove 6 in FIG. 1, the bending die 4 may be formed by laminating a plurality of grooves 6 corresponding to the bending radius of the pipe 2.

曲げ型４に対向して、曲げアーム８上に締め型１２が移動可能に支承されており、締め型１２は第２シリンダ１４により駆動されて、パイプ２を曲げ型４と締め型１２とにより挟持できるように構成されている。また、曲げ型４に接近してワイパ型１６が配置されており、ワイパ型１６に対向して圧力型１８が摺動台２０上に移動可能に支持されている。圧力型１８は第３シリンダ２２により駆動されて、パイプ２に当てられ、曲げ加工時の反力を受けることができるように構成されている。摺動台２０はパイプ２の軸方向に摺動可能に支持されており、シリンダ２４により駆動されるように構成されている。   A clamping die 12 is movably supported on the bending arm 8 so as to face the bending die 4, and the clamping die 12 is driven by the second cylinder 14, so that the pipe 2 is moved by the bending die 4 and the clamping die 12. It is configured so that it can be pinched. Further, a wiper mold 16 is disposed close to the bending mold 4, and a pressure mold 18 is movably supported on the slide table 20 so as to face the wiper mold 16. The pressure die 18 is driven by the third cylinder 22 and applied to the pipe 2 so as to receive a reaction force during bending. The slide table 20 is supported so as to be slidable in the axial direction of the pipe 2 and is configured to be driven by a cylinder 24.

曲げ機構１の両側には、一対の端末加工用パンチ２６，２８が配置されている。一対の端末加工用パンチ２６，２８は、曲げ型４の溝６に装着した状態のパイプ２の両端に、パイプ２の端と対向して、パイプ２と同軸上に配置されている。本実施形態の一対の端末加工用パンチ２６，２８は、パイプ２の両端の真円度を矯正するもので、それぞれパイプ２内に挿入される矯正軸部２６ａ，２８ａと、パイプ２の内径よりも大きな鍔部２６ｂ，２８ｂとを備えている。   On both sides of the bending mechanism 1, a pair of terminal processing punches 26 and 28 are arranged. The pair of end processing punches 26 and 28 are disposed coaxially with the pipe 2 at both ends of the pipe 2 mounted in the groove 6 of the bending die 4 so as to face the ends of the pipe 2. The pair of end processing punches 26 and 28 of the present embodiment corrects the roundness of both ends of the pipe 2, and each of the correction shaft portions 26 a and 28 a inserted into the pipe 2 and the inner diameter of the pipe 2. Are also provided with large flanges 26b and 28b.

一方の端末加工用パンチ２６は、チャック３０内に設けられており、チャック３０はパイプ２の外周を把持する構成のものである。チャック３０は図示しない移動台に載置されており、移動台は駆動機構３１により駆動されてパイプ２の軸方向に移動し、チャック３０を軸方向に移動することができるように構成されている。
One terminal processing punch 26 is provided in the chuck 30, and the chuck 30 is configured to grip the outer periphery of the pipe 2. The chuck 30 is mounted on a movable table (not shown), and the movable table is driven by a drive mechanism 31 to move in the axial direction of the pipe 2 so that the chuck 30 can be moved in the axial direction . .

他方の端末加工用パンチ２８はシリンダ３２によりパイプ２の軸方向に移動できるように構成されている。第１〜第３シリンダ１０，１４，２２、シリンダ２４、駆動機構３１、シリンダ３２は制御回路３４により制御されるように接続されている。尚、一方の端末加工用パンチ２６を中空に形成して、パイプ２内に図示しない芯金を挿入するように構成してもよい。一対の端末加工用パンチ２６，２８は、真円度矯正用に限らず、フレア加工用のもの等でもよい。   The other end machining punch 28 is configured to be movable in the axial direction of the pipe 2 by a cylinder 32. The first to third cylinders 10, 14, 22, the cylinder 24, the drive mechanism 31, and the cylinder 32 are connected so as to be controlled by the control circuit 34. Note that one end processing punch 26 may be formed hollow and a core metal (not shown) may be inserted into the pipe 2. The pair of terminal processing punches 26 and 28 are not limited to roundness correction but may be flaring processing or the like.

次に、前述した本実施形態の曲げ加工装置の作動について説明する。
まず、所定の長さに切断したパイプ２の端をチャック３０により把持して、チャック３０を移動してパイプ２の曲げ加工箇所を曲げ型４の溝６に装着する。そして、第２シリンダ１４を駆動して締め型１２を移動し、曲げ型４と締め型１２とによりパイプ２を把持する。また、第３シリンダ２２を駆動して圧力型１８を移動し、ワイパ型１６と圧力型１８とによりパイプ２を挟持する。 Next, the operation of the bending apparatus of this embodiment described above will be described.
First, the end of the pipe 2 cut to a predetermined length is gripped by the chuck 30, the chuck 30 is moved, and the bending portion of the pipe 2 is attached to the groove 6 of the bending die 4. Then, the second cylinder 14 is driven to move the clamping die 12, and the pipe 2 is gripped by the bending die 4 and the clamping die 12. Further, the third cylinder 22 is driven to move the pressure die 18, and the pipe 2 is sandwiched between the wiper die 16 and the pressure die 18.

次に、駆動機構３１、シリンダ３２を駆動して、一対の端末加工用パンチ２６，２８をパイプ２の端に向かって同時に軸方向に移動する。そして、一対の端末加工用パンチ２６，２８の矯正軸部２６ａ，２８ａをパイプ２に、パイプ２の端が鍔部２６ｂ，２８ｂに当たるまで挿入する。これにより、パイプ２の両端が同時に端末加工されて、パイプ２の端の真円度を矯正する。その際、チャック３０による把持は開放するようにするとよい。   Next, the drive mechanism 31 and the cylinder 32 are driven, and the pair of end processing punches 26 and 28 are simultaneously moved in the axial direction toward the end of the pipe 2. Then, the straightening shaft portions 26a, 28a of the pair of end processing punches 26, 28 are inserted into the pipe 2 until the end of the pipe 2 contacts the flange portions 26b, 28b. As a result, both ends of the pipe 2 are simultaneously machined to correct the roundness of the end of the pipe 2. At that time, the gripping by the chuck 30 is preferably released.

その際、ワイパ型１６と圧力型１８とによるパイプ２の外周の把持力は弱く、また、曲げ型４と締め型１２とによりパイプ２の外周を把持しているが、パイプ２が変形しないように把持しているので、パイプ２に一方向から軸方向の作用力が働くと、パイプ２は動いてしまう。一対の端末加工用パンチ２６，２８を同時に駆動してパイプ２の両端を端末加工するので、パイプ２の外周を曲げ型４と締め型１２とにより把持しているだけの状態であっても、パイプ２は軸方向に動かない。   At that time, the gripping force on the outer periphery of the pipe 2 by the wiper mold 16 and the pressure mold 18 is weak, and the outer periphery of the pipe 2 is gripped by the bending mold 4 and the clamping mold 12, but the pipe 2 is not deformed. Therefore, when an acting force in the axial direction is applied to the pipe 2 from one direction, the pipe 2 moves. Since both ends of the pipe 2 are end-processed by driving the pair of end processing punches 26 and 28 at the same time, even when the outer periphery of the pipe 2 is only gripped by the bending die 4 and the clamping die 12, The pipe 2 does not move in the axial direction.

端末加工した後、本実施形態では、シリンダ３２を駆動して他方の端末加工用パンチ２８を軸方向に移動して、パイプ２の端から引き抜く。そして、第１シリンダ１０を駆動して曲げ型４を中心にして曲げアーム８を回転させて、締め型１２を曲げ型４の廻りに公転させると共に、シリンダ２４を駆動して摺動台２０により圧力型１８をパイプ２の軸方向に移動して、曲げ加工を行なう。   After the end machining, in the present embodiment, the cylinder 32 is driven and the other end machining punch 28 is moved in the axial direction and pulled out from the end of the pipe 2. Then, the first cylinder 10 is driven to rotate the bending arm 8 around the bending die 4 to revolve the clamping die 12 around the bending die 4, and the cylinder 24 is driven by the slide base 20. The pressure die 18 is moved in the axial direction of the pipe 2 to perform bending.

本実施形態では、ドローベンドが行われるので、パイプ２が曲げ型４に巻き付けられるようにして曲げ加工が行われる。その際、駆動機構３１を駆動して、端末加工用パンチ２６の鍔部２６ｂによりパイプ２に軸方向加圧力を付与するようにしてもよい。   In the present embodiment, since draw bend is performed, bending is performed so that the pipe 2 is wound around the bending die 4. At that time, the driving mechanism 31 may be driven to apply axial pressure to the pipe 2 by the flange portion 26b of the terminal processing punch 26.

このように、一対の端末加工用パンチ２６，２８をパイプ２の端に向かって同時に軸方向に移動して挿入するので、パイプ２を強固に把持する必要はなく、簡単な構成で、曲げ加工を行なうと共に、端末加工をも簡単に行うことができる。一方の端末加工用パンチ２６をチャック３０に設けることにより、パイプ２の供給とを兼用できる構成を取ることができる。一方の端末加工用パンチ２６に鍔部２６ｂを設けることにより、曲げ加工時に軸方向加圧力を付与することも容易である。 Thus, since the insert by moving the pair of end processing punch 26 and 28 in the axial direction at the same time towards the end of the pipe 2, it is not necessary to firmly grip the pipe 2, in easy single of configuration, In addition to bending, terminal processing can be easily performed. By providing one end machining punch 26 on the chuck 30, it is possible to adopt a configuration that can also be used for supplying the pipe 2. By providing the flange portion 26b on one terminal processing punch 26, it is also easy to apply an axial pressure during bending.

以上本発明はこの様な実施形態に何等限定されるものではなく、本発明の要旨を逸脱しない範囲において種々なる態様で実施し得る。   The present invention is not limited to such embodiments as described above, and can be implemented in various modes without departing from the gist of the present invention.
