Description

この発明は、結束用のフープ材の先端部近傍に装着したシール材の前後位置でフープ材を曲げ加工するフープ材曲げ加工方法、及び、シール材の前後位置でフープ材を曲げ加工してなる結束部材を作製する結束部材作製装置に関する。   The present invention is a hoop material bending method in which a hoop material is bent at a front and rear position of a sealing material mounted in the vicinity of a tip portion of a binding hoop material, and a hoop material is bent at a front and rear position of the sealing material. The present invention relates to a binding member manufacturing apparatus for manufacturing a binding member.

コイル状に巻き取った圧延鋼板、あるいは、素材の圧延鋼板を所定幅にスリットして再びコイル状に巻き取ったスリットコイルを結束する際、一般に鋼製のフープ材が用いられている。
その場合、図13(イ)に示すように、フープ材1の先端部近傍に扁平C形断面のシール材2を装着してなる結束部材3を予め作製しておく。その際、シール材2がフープ材1から抜け落ちないように、フープ材1のシール材2より前方側位置を概ねV字形に折り返し(V字曲げ部をaで示す)、シール材より後方側位置を鈍角に折り曲げておく(鈍角曲げ部をbで示す)。結束部材3の先端部近傍を図13(ロ)に斜視図で示す。
そして、図14のように、フープ材1をスリットコイル4の外周に廻らせて、フープ材1の他方の端部をシール材2内に挿通させる。次いで、フープ材締め付け工具にてフープ材1を締め付けた後、シール材封緘工具にてシール材2をその幅方向両側から圧縮して封緘すると、シール材2内で重なった2枚のフープ材がシール材2で互いに固定され、スリットコイル4はばらけないように結束される。
A steel hoop material is generally used when a rolled steel plate wound in a coil shape or a slit coil obtained by slitting a rolled steel plate as a raw material into a predetermined width and winding it again in a coil shape is bundled.
In this case, as shown in FIG. 13 (a), a bundling member 3 is prepared in advance by mounting a sealing material 2 having a flat C-shaped cross section in the vicinity of the tip of the hoop material 1. At that time, the front side position of the hoop material 1 is folded back into a substantially V shape (the V-shaped bent portion is indicated by a) so that the sealing material 2 does not fall out of the hoop material 1, and the rear side position from the sealing material. Is bent at an obtuse angle (the obtuse bend is indicated by b). FIG. 13B is a perspective view showing the vicinity of the tip of the binding member 3.
Then, as shown in FIG. 14, the hoop material 1 is turned around the outer periphery of the slit coil 4 and the other end of the hoop material 1 is inserted into the seal material 2. Next, after the hoop material 1 is tightened with the hoop material tightening tool, when the sealing material 2 is compressed and sealed from both sides in the width direction with the sealing material sealing tool, the two hoop materials overlapped in the sealing material 2 are obtained. The slit coils 4 are fixed to each other with the sealing material 2 so that they are not separated.

上記のように、予めフープ材1の先端部にシール材2を装着しその前後部を曲げ加工しておく作業、すなわち結束部材3を作製する作業は、従来、手作業で行うのが一般的であるが、図15に示すようなフープ材曲げ加工装置7も提案されている(特許文献1)。
このフープ材曲げ加工装置7は、フープ材切断機8(その上下刃を8a、8bで示す)の前方にフープ材先端部折り曲げ装置9と後端部折り曲げ装置10をそれぞれ設置し、フープ材先端部折り曲げ装置9と後端部折り曲げ装置10との間にシール材嵌着装置11を設けた構成である。シール材嵌着装置11では、シール材を手作業でシールケース11aにセットする。
前記フープ材先端部折り曲げ装置9は、切断機8の近傍に配置され、フープ材ガイド12、13、フープ材1の保持・案内機能を有するフープ材先端部折り曲げ具14、該フープ材先端部折り曲げ具14を回動する回動体15、円柱状の突起体16から構成されている。また、フープ材1の後端部折り曲げ具10は、上金型10aと下金型10bとでフープ材1を挟んでこれを折り曲げる構成である。
特開2003−212206
As described above, the operation of attaching the sealing material 2 to the tip of the hoop material 1 in advance and bending the front and rear portions thereof, that is, the operation of manufacturing the bundling member 3 is conventionally performed manually. However, a hoop material bending apparatus 7 as shown in FIG. 15 has also been proposed (Patent Document 1).
The hoop material bending apparatus 7 is provided with a hoop material front end bending device 9 and a rear end bending device 10 in front of a hoop material cutting machine 8 (the upper and lower blades are indicated by 8a and 8b), respectively. In this configuration, a sealing material fitting device 11 is provided between the partial bending device 9 and the rear end bending device 10. In the sealing material fitting device 11, the sealing material is manually set in the sealing case 11a.
The hoop material front end bending device 9 is disposed in the vicinity of the cutting machine 8 and has hoop material guides 12 and 13, a hoop material front end bending tool 14 having a function of holding and guiding the hoop material 1, and the hoop material front end bending unit. A rotating body 15 that rotates the tool 14 and a cylindrical protrusion 16 are included. Further, the rear end bending tool 10 of the hoop material 1 has a configuration in which the hoop material 1 is sandwiched between the upper mold 10a and the lower mold 10b and bent.

フープ材1を折り曲げるにはかなり大きな力を要するので、フープ材1の先端部近傍の2箇所を曲げ加工をする作業を手作業で行うのは、多大の労力を要し、作業効率が悪い。
これに対して、特許文献1のフープ材曲げ加工装置7によれば、フープ材曲げ加工の労力及び作業効率の問題は改善される。しかし、このフープ材曲げ加工装置7は、シール材2をシールケース11aに手作業で供給する点で、作業効率が充分改善されたとは言い難い。
また、フープ材1の送り方向後端部(フープ材1の使用状態では先端部となる)を曲げ加工する構成なので、フープ材1の後端の位置決めが必要であるが、引用文献1では後端位置決めを手作業で行うものと思われ、作業性が悪い。すなわち、位置決め機構を設ける場合、フープ材の先端位置決めであれば単にストッパを設けるだけで済むので簡単であるのに対して、後端の位置決め方式では、必ずしも簡単な機構とはならない。
フープ材先端部折り曲げ装置9の詳細構造は必ずしも明瞭ではないが、やや構造が複雑になると思われる。
Since a considerably large force is required to bend the hoop material 1, performing the work of bending the two portions in the vicinity of the front end portion of the hoop material 1 requires a lot of labor, and the work efficiency is poor.
On the other hand, according to the hoop material bending apparatus 7 of Patent Document 1, the problems of labor and work efficiency of the hoop material bending process are improved. However, it is hard to say that the hoop material bending apparatus 7 has sufficiently improved work efficiency in that the seal material 2 is manually supplied to the seal case 11a.
Further, since the rear end of the hoop material 1 in the feeding direction (the front end when the hoop material 1 is used) is bent, the rear end of the hoop material 1 needs to be positioned. It seems that the end positioning is performed manually, and the workability is poor. In other words, when the positioning mechanism is provided, it is simple because it is only necessary to provide a stopper if the tip of the hoop material is positioned, whereas the rear end positioning method is not always a simple mechanism.
Although the detailed structure of the hoop material front end bending device 9 is not necessarily clear, the structure is somewhat complicated.

本発明は上記従来の欠点を解消するためになされたもので、シール材を端部に装着したフープ材のシール材前後2箇所の曲げ加工作業を自動的にかつ能率的に行うことができるフープ材曲げ加工方法、及びこのフープ材曲げ加工方法を用いた簡単な構造の結束部材作製装置を提供することを目的とする。   The present invention was made to eliminate the above-mentioned conventional drawbacks, and can automatically and efficiently perform bending work at two locations before and after the sealing material of the hoop material with the sealing material attached to the end.

According to the hoop material bending method and the bundling member manufacturing apparatus of the present invention, the hoop material is abutted against the stopper surface of the V-shaped bending mold, and the V-shaped bending mold is simply rotated. The tip of the hoop material can be folded back into a V shape while restraining the hoop material with the mold and the thin projecting member. Although the V-shaped bending process of the tip portion of the hoop material is not always easy, the V-shaped bending process is realized by a V-shaped bending apparatus having a simple structure.
Next, a bundling member formed by bending the hoop material at the front and back positions of the sealing material mounted in the vicinity of the front end portion of the hoop material can be obtained by obtuse angle bending of the hoop material sealing material by the obtuse angle bending device. it can. As described above, it is possible to automatically and efficiently perform the work of bending the two parts before and after the seal material of the hoop material in which the seal material is attached to the end, that is, the work of producing the binding member.

鈍角曲げ装置を請求項5のような構造とすると、フープ材のシール材を装着した部分を曲げ用溝に嵌合させた状態で鈍角曲げ用金型を回転させるだけで、フープ材のシール材より後方側位置の鈍角曲げ加工を行うことができる。このように、鈍角曲げ加工が曲げ用溝を持つ鈍角曲げ用金型という簡単な構造で実現される。   When the obtuse angle bending apparatus has the structure as defined in claim 5, the hoop material sealing material can be obtained by simply rotating the obtuse angle bending mold with the portion of the hoop material sealing material fitted in the bending groove. An obtuse angle bending process at a more rear side position can be performed. In this way, the obtuse angle bending process is realized with a simple structure of an obtuse angle bending mold having a bending groove.

鈍角曲げ装置を請求項6のような構造とすると、鈍角曲げ用金型が全体として下降しながら回転して鈍角曲げ加工を行うので、フープ材の鈍角曲げ部の位置がフープ材の上流側高さ位置より高くならずに(したがって、フープ材の上流側に無用な曲がりが生じないように)、鈍角曲げを行うことができる。   If the obtuse angle bending apparatus is structured as in claim 6, the obtuse angle bending mold rotates and moves obtusely to perform obtuse angle bending, so that the position of the obtuse angle bending portion of the hoop material is higher than the upstream side of the hoop material. Obtuse angle bending can be performed without being higher than the position (thus preventing unnecessary bending from occurring upstream of the hoop material).

シール材供給装置を請求項7のような構造とすると、簡単な構造でもって、シール材をフープ材の先端近傍に装着する作業を自動的かつ円滑に行うことができる。
請求項8のような構造のシール材供給装置は、シール材をフープ材の先端近傍に装着する作業を円滑に行なう上で極めて適切である。
When the sealing material supply device has the structure as in claim 7, the operation of mounting the sealing material near the tip of the hoop material can be performed automatically and smoothly with a simple structure.
The sealing material supply apparatus having the structure as described in claim 8 is extremely suitable for smoothly performing the work of mounting the sealing material near the tip of the hoop material.

請求項9のように、鈍角曲げ装置がフープ材送り方向と直角方向に退避可能である構成は、鈍角曲げ用金型が曲げ用溝を持つ構造であることに対して極めて適切であり、フープ材の2箇所を曲げ加工された結束部材を円滑に取り出すことができる。   The configuration in which the obtuse angle bending apparatus can be retracted in a direction perpendicular to the hoop material feeding direction as in claim 9 is extremely suitable for the structure in which the obtuse angle bending mold has a bending groove. A binding member obtained by bending two portions of the material can be smoothly taken out.

以下、本発明のフープ材曲げ加工方法及び結束部材作製装置の実施例を、図1〜図14を参照して説明する。   Embodiments of a hoop material bending method and a binding member manufacturing apparatus according to the present invention will be described below with reference to FIGS.

なお、ここで、V字曲げとは、曲げた角の両側部分が互いに傾斜して先窄まり状をなしているという意味であって、シャープな角が形成される曲げという意味ではない。曲げた角に注目した時は、丸みを持つ角が形成される曲げという点でU字曲げということもできる曲げである。
この結束部材3は、例えば図14で説明したようにして、例えばスリットコイル4をばらけないように結束することができる。但し、この結束部材3は、コイルに限らず種々の鋼材の結束、さらには鋼材に限らず種々の被結束材の結束に用いることができる。

Here, the V-shaped bending means that both side portions of the bent corner are inclined with respect to each other to form a tapered shape, and does not mean a bending in which a sharp corner is formed. When attention is paid to the bent corner, it is a bend that can also be called a U-shaped bend in that a rounded corner is formed.
This bundling member 3 can be bundled, for example, as described with reference to FIG. 14 so that the slit coil 4 does not come apart. However, this bundling member 3 can be used not only for coils but also for bundling various steel materials, and for bundling various bundling materials without being limited to steel materials.

The detailed structure of the V-shaped bending device 26 and the obtuse angle bending device 27 will be described mainly with reference to FIGS.
The V-shaped bending device 26 includes a generally vertical stopper surface 34 that receives the tip of the hoop material 1 that is fed horizontally, a generally horizontal surface 35 that extends upstream from the upper end of the stopper surface 34, and the surface 35.

Reference numeral 41 denotes a rotary shaft that is fitted into the circular shaft hole 37 b of the V-shaped bending die 37 and serves as the rotation center of the V-shaped bending die 37, and 42 is an air cylinder that rotationally drives the V-shaped bending die 37. It is. The piston rod 42 a of the air cylinder 42 is connected via a pin 43 to a bracket 37 a attached to the upper surface of the V-shaped bending die 37.
The air cylinder 42 is a clevis type, and is attached to the frame 50 of the hoop material bending portion 52 by a pin 44 so as to be swingable.

前記鈍角曲げ装置27は、フープ材1に装着されているシール材2を嵌合させることができる概ね水平な曲げ用溝39aを持つ、鈍角曲げ用金型としての溝付き円筒体39を備え、この溝付き円筒体(鈍角曲げ用金型)39はフープ材1のシール材2より後端側位置の鈍角曲げ角度と概ね同程度の角度だけ回転することができる。
溝付き円筒体39に取り付けたブラケット39bに、エアシリンダ46のピストンロッド46aが連結されて、このエアシリンダ46により回転駆動される。

上記の結束部材作製装置21の動作を説明する。図1、図2に示すように、フープコイル1Aから送り出されたフープ材1は、水平テーブル24上を図示略のガイドにより案内されて前方に送り出される。
この時、シール材供給装置25において、図3、図4にも示すように、シールマガジン30内の最下段のシール材2が水平テーブル24bの上面より若干低いシール材受け台28上にあるので、フープ材1はその最下段のシール材2の内側を通過し、さらに、溝付き円筒体39の曲げ用溝39aを通って、V字曲げ用金型37のストッパ面34に当たる。図5はこの時の状態を示す。
Operation | movement of said binding member preparation apparatus 21 is demonstrated. As shown in FIGS. 1 and 2, the hoop material 1 delivered from the hoop coil 1 </ b> A is guided forward on the horizontal table 24 by a guide (not shown).
At this time, in the sealing material supply device 25, as shown in FIGS. 3 and 4, the lowermost sealing material 2 in the seal magazine 30 is on the sealing material cradle 28 slightly lower than the upper surface of the horizontal table 24b. The hoop material 1 passes through the inside of the lowermost seal material 2, passes through the bending groove 39 a of the grooved cylindrical body 39, and hits the stopper surface 34 of the V-shaped bending die 37. FIG. 5 shows the state at this time.

次いで、シール材供給装置25のエアシリンダ33が作動してシール材押出しブロック32が前進すると、このシール材押出しブロック32の上面(水平テーブル24bの上面と同じ高さ)より低いシール材受け台28上にあるシール材2は、このシール材押出しブロック32により前方に押され、図6に示すように、シール材押出しブロック32の前進限位置で溝付き円筒体39の曲げ用溝39a内に収容される。
この時、溝付き円筒体39の曲げ用溝39aの入口側の両角部(下縁及び上縁)に、フープ材が進入し易いように逃がし(案内用のR(アール))が付けられているので、シール材2はスムーズに曲げ用溝39a内に挿入される。
Next, when the air cylinder 33 of the sealing material supply device 25 is operated to advance the sealing material extrusion block 32, the sealing material cradle 28 lower than the upper surface of the sealing material extrusion block 32 (the same height as the upper surface of the horizontal table 24b). The upper sealing material 2 is pushed forward by the sealing material extrusion block 32, and is accommodated in the bending groove 39a of the grooved cylindrical body 39 at the forward limit position of the sealing material extrusion block 32 as shown in FIG. Is done.
At this time, relief (guide R (R)) is attached to both corners (lower edge and upper edge) on the inlet side of the bending groove 39a of the grooved cylindrical body 39 so that the hoop material can easily enter. Therefore, the sealing material 2 is smoothly inserted into the bending groove 39a.

続いて、V字曲げ装置26のエアシリンダ42が作動して、V字曲げ用金型37がピン41を中心として例えば80〜90°下方に回転すると、図7に示すように、フープ材1の先端部近傍が概ねV字形に折り曲げられる。
この工程を詳細に説明すると、V字曲げ用金型37が回転し始めると、フープ材1は、まずV字曲げ用金型37の水平部35で押し下げられ、続いて逆V字形凹所36の前方側縁部近傍36aで押し下げられるが、先端がストッパ面34で拘束されているフープ材1は、V字曲げ用金型37の回転に伴って、薄形突出部材38の先端に近い部分が上に凸に湾曲して逆V字形凹所36の後方側縁部近傍36bの内面になじむ。
V字曲げ用金型37がさらに回転すると、フープ材1は概ね薄形突出部材38の先端部を基点として下方に押し曲げられていく。V字曲げ用金型37がさらに回転すると、相対的に薄形突出部材38の先端部が逆V字形凹所36の奥端に向けて次第に入り込んでいくので、フープ材1は、薄形突出部材38の先端部により逆V字形凹所36の奥端側に押し込まれ、図7のように、薄形突出部材38の先端部を曲げ支点としてV字形に折り曲げられる。V字曲げの角部をaで示す。フープ材1の先端部が略V字形に折り曲げられていく様子の概略を図12に示す。
Subsequently, when the air cylinder 42 of the V-shaped bending device 26 is activated and the V-shaped bending die 37 rotates about 80 to 90 degrees around the pin 41, as shown in FIG. The vicinity of the front end of the is bent into a generally V shape.
This process will be described in detail. When the V-shaped bending mold 37 starts to rotate, the hoop material 1 is first pushed down by the horizontal portion 35 of the V-shaped bending mold 37 and then the inverted V-shaped recess 36. The hoop material 1, which is pushed down in the vicinity of the front edge 36 a, but whose tip is constrained by the stopper surface 34, is a portion close to the tip of the thin protruding member 38 as the V-shaped bending die 37 rotates. Is convex upward and fits to the inner surface of the vicinity 36b of the rear side edge of the inverted V-shaped recess 36.
When the V-shaped bending die 37 further rotates, the hoop material 1 is pushed and bent downward with the tip of the thin projecting member 38 as a base point. When the V-shaped bending die 37 is further rotated, the distal end portion of the relatively thin projection member 38 gradually enters toward the back end of the inverted V-shaped recess 36, so that the hoop material 1 is a thin projection. The tip of the member 38 is pushed into the back end side of the inverted V-shaped recess 36 and is bent into a V shape with the tip of the thin projection member 38 as a bending fulcrum as shown in FIG. The corner of the V-bend is indicated by a. FIG. 12 shows an outline of how the tip of the hoop material 1 is bent into a substantially V shape.

続いて、V字曲げ用金型37が上方に復帰回転して退避した後、鈍角曲げ装置27のエアシリンダ46が作動して溝付き円筒体39が回転すると、その曲げ用溝39a内に嵌入しているシール材2が溝付き円筒体39の回転角度とともに傾斜していき、そのシール材2と共にフープ材1が傾斜していくので、図8のように、曲げ用溝39aの入口近傍(右側)でフープ材1が鈍角に折り曲げられる。鈍角曲げの角部をbで示す。
この鈍角曲げ工程において、シール材2はフープ材1に沿って下方に滑り落ちることは防止される。すなわち、溝付き円筒体39部分を拡大した図9において、図9(イ)の状態から溝付き円筒体39が回転を始めると、シール材2は、図9(ロ)に示すように、曲げ用溝39aの出口部分(左側)では、フープ材1によって曲げ用溝39aの上面に押し付けられ、曲げ用溝39aの入口部分(右側)では、フープ材1によって曲げ用溝39aの下面に押し付けられるので、その2箇所での互いに逆向きの押し付け力による摩擦力でシール材2がフープ材1に沿って滑り落ちることを防止される。
なお、鈍角曲げ工程の際にシール材押出しブロック32が図8のように前進限位置に留まっていると、鈍角曲げが始まる際に、シール材2が曲げ用溝39aから少なくとも上流側に逃げてしまうことはない。しかし、鈍角曲げ工程が開始する前にシール材押出しブロック32を後退させ、初期位置に復帰させてもよい。
Subsequently, after the V-shaped bending die 37 is rotated upward and retracted, when the air cylinder 46 of the obtuse angle bending device 27 is operated to rotate the grooved cylindrical body 39, the grooved cylindrical body 39 is inserted into the bending groove 39a. Since the sealing material 2 is inclined with the rotational angle of the grooved cylindrical body 39 and the hoop material 1 is inclined together with the sealing material 2, the vicinity of the inlet of the bending groove 39a (see FIG. 8) On the right side) the hoop material 1 is bent at an obtuse angle. The corner of the obtuse bend is indicated by b.
In this obtuse angle bending process, the sealing material 2 is prevented from sliding down along the hoop material 1. That is, in FIG. 9 in which the grooved cylindrical body 39 is enlarged, when the grooved cylindrical body 39 starts rotating from the state of FIG. 9A, the sealing material 2 is bent as shown in FIG. The outlet portion (left side) of the groove 39a is pressed against the upper surface of the bending groove 39a by the hoop material 1, and the inlet portion (right side) of the bending groove 39a is pressed against the lower surface of the bending groove 39a by the hoop material 1. Therefore, it is possible to prevent the sealing material 2 from sliding along the hoop material 1 by the frictional force caused by the mutually opposite pressing forces at the two locations.
If the sealing material pushing block 32 remains in the forward limit position as shown in FIG. 8 during the obtuse angle bending process, the sealing material 2 escapes at least upstream from the bending groove 39a when the obtuse angle bending starts. There is no end. However, before the obtuse angle bending process starts, the sealing material extrusion block 32 may be retracted and returned to the initial position.

続いて、フープ材曲げ加工部52の全体が図10に示すように、フープ材送り方向と直角な方向に移動して退避する。これにより、曲げ加工されたシール材付きフープ材1は鈍角曲げ装置27の溝付き円筒体39の曲げ用溝39aから外れる。   Subsequently, as shown in FIG. 10, the entire hoop material bending section 52 moves and retracts in a direction perpendicular to the hoop material feed direction. As a result, the bent hoop material 1 with the sealing material is detached from the bending groove 39a of the grooved cylindrical body 39 of the obtuse angle bending device 27.

次いで、フープ材切断機23によりフープ材1を切断すると、フープ材1の先端近傍にシール材2が装着されかつその前後位置が折り曲げられて抜け落ち防止が図られた結束部材3が得られる。その結束部材3は手で取り出す。
なお、上述のように、フープ材を切断する前に、フープ材曲げ加工部52をラインと直角方向に(フープ材送り方向と直角な方向に)退避させると、フープ材の切断長さは自由に変えることができる。
Next, when the hoop material 1 is cut by the hoop material cutting machine 23, the bundling member 3 is obtained in which the seal material 2 is mounted in the vicinity of the tip of the hoop material 1 and the front and rear positions thereof are bent to prevent falling off. The binding member 3 is taken out by hand.
As described above, if the hoop material bending portion 52 is retracted in a direction perpendicular to the line (in a direction perpendicular to the hoop material feed direction) before cutting the hoop material, the cutting length of the hoop material is free. Can be changed to

図11に鈍角曲げ装置の他の実施例を示す。この鈍角曲げ装置27’は、溝付き円筒体39’が、前述の実施例のように単に回転するのではなく、2点鎖線で示した初期位置から実線で示した位置まで、全体として下降しながら回転して、フープ材1の鈍角曲げを行う。
溝付き円筒体39が単に回転する前述の実施例では、図8に示されるように、シール材後方側の鈍角曲げ部bの位置が高く上がって、例えばシール材供給装置25の近傍に無用な曲げが生じる恐れがあるが、この実施例によれば、フープ材1の鈍角曲げ部bの位置がフープ材1の上流側高さ位置より高くならずに(したがって、フープ材1の上流側に無用な曲がりが生じないように)、鈍角曲げを行うことができる。
FIG. 11 shows another embodiment of the obtuse angle bending apparatus. In the obtuse angle bending device 27 ′, the grooved cylindrical body 39 ′ is not simply rotated as in the above-described embodiment, but is lowered as a whole from the initial position indicated by the two-dot chain line to the position indicated by the solid line. While rotating, the obtuse angle bending of the hoop material 1 is performed.
In the above-described embodiment in which the grooved cylindrical body 39 simply rotates, as shown in FIG. 8, the position of the obtuse bend b on the rear side of the sealing material rises high, and is unnecessary in the vicinity of the sealing material supply device 25, for example. Although bending may occur, according to this embodiment, the position of the obtuse angle bending portion b of the hoop material 1 does not become higher than the height position on the upstream side of the hoop material 1 (therefore, on the upstream side of the hoop material 1). An obtuse angle bend can be performed so that no unwanted bending occurs.

上述した各実施例では、V字曲げ装置の一部を構成する薄形突出部材38を、鈍角曲げ装置27の溝付き円筒体39と一体に形成したが、実施例の薄形突出部材38と概ね同様な形状及び位置の部材を溝付き円筒体とは別個に設けてもよい。その場合は、その薄形突出部材が鈍角曲げ加工時に妨げとならないように退避可能にする必要がある。   In each of the above-described embodiments, the thin protruding member 38 constituting a part of the V-shaped bending device is formed integrally with the grooved cylindrical body 39 of the obtuse angle bending device 27. Members having substantially the same shape and position may be provided separately from the grooved cylinder. In that case, the thin projecting member needs to be retractable so as not to hinder obtuse bending.
