【考案の詳細な説明】
本考案はパイプベンダーにおいて、パイプの支持を行な
う起上り弐ローラに関する。[Detailed Description of the Invention] The present invention relates to a rising roller for supporting a pipe in a pipe bender.
フランジを有する曲り管を得る場合、一般にフランジの
溶接を行なった後に曲げ加工を行なう。When obtaining a bent pipe having flanges, the bending process is generally performed after the flanges are welded.
曲げの後にフランジの溶接を行なうには、溶接に際し不
規則な管を立てて固定しなければならず不安定だからで
ある。This is because if the flange is welded after bending, the irregular pipe must be erected and fixed during welding, making it unstable.
しかし、フランジを有する管をパイプベンダーで曲げる
場合、受はローラで支持されたパイプが曲げによって管
軸方向に移動したり、あるいは寸法法めのために受はロ
ーラ上でパイプを管軸方向に移動させたりすることから
、パイプのフランジが受はローラに引っ掛かる問題があ
る。However, when bending a pipe with a flange using a pipe bender, the pipe supported by rollers on the holder may move in the axial direction of the pipe due to bending, or the holder may move the pipe on the rollers in the axial direction for dimensioning. When moving the pipe, there is a problem that the flange of the pipe gets caught on the roller.
また、パイプの外面に金物が取付けられている場合も同
様な問題がある。A similar problem also occurs when hardware is attached to the outer surface of the pipe.
本考案は上記のフランジ等の引っ掛かり問題を解消した
もので、以下その一実施例を図面に基づいて説明する。The present invention solves the above-mentioned problem of flanges and the like getting caught, and one embodiment thereof will be described below with reference to the drawings.
１はパイプベンダーであり、パイプ３を挾む一対の曲げ
ローラ２からなる。Reference numeral 1 denotes a pipe bender, which consists of a pair of bending rollers 2 that sandwich a pipe 3.
パイプベンダー１の一側にはパイプ３を支持する位置固
定の固定受はローラ４が複数個配置され、固定受はロー
ラ４より離れて起上り式ローラ５が設けられている。On one side of the pipe bender 1, a plurality of rollers 4 are disposed as stationary supports that support the pipe 3, and an upright roller 5 is provided at a distance from the rollers 4.
起上り式ローラ５は、固定台６に水平軸心１回りで回動
可能に支持された可動枠７に２個の受はローラ８ａ＊８
ｂを取付けたものである。The rising type roller 5 is mounted on a movable frame 7 which is rotatably supported on a fixed base 6 so as to be rotatable around a horizontal axis, and two rollers 8a*8 are mounted on the movable frame 7.
b is attached.
可動枠７は２本の直角に配置されたアーム９ａ、９ｂと
、これらアーム９ ａ、 ９ ｂを結合する斜材１０
とでなる。The movable frame 7 has two arms 9a and 9b arranged at right angles, and a diagonal member 10 that connects these arms 9a and 9b.
It becomes.
受はローラ８ａ、８ｂはアーム９ａ、９ｂの遊端に取付
けられており、したがって互いに可動枠７の回動力向に
離れて配置されている。The rollers 8a and 8b are attached to the free ends of the arms 9a and 9b, and are therefore spaced apart from each other in the direction of rotation of the movable frame 7.
１１ａ、ｆｌｂは可動枠７を保持する位置固定のストッ
パであり、可動枠７はいずれか一方のアーム９ａ、９ｂ
が倒れてストッパｌｌａ、ｌｌｂに接当したときに他方
のアーム９ａ＊９ｂが直立する。11a and flb are position-fixed stoppers that hold the movable frame 7, and the movable frame 7 is attached to one of the arms 9a and 9b.
When the arm 9 falls down and contacts the stoppers lla and llb, the other arm 9a*9b stands upright.
換言すれば、このとき他方のアーム９ａ、９ｂの受はロ
ーラ８ａ、８ｂが上端に位置する。In other words, at this time, the rollers 8a, 8b are located at the upper ends of the supports of the other arms 9a, 9b.
１２は可動枠７の斜材１０と固定台６との間に張設した
引張ばねである。Reference numeral 12 denotes a tension spring tensioned between the diagonal member 10 of the movable frame 7 and the fixed base 6.
つぎに作用について説明する。Next, the effect will be explained.
パイプ３は端部にフランジ３ａを有し、内部には曲げ時
の偏平化を防ぐための心金１３が挿通されている。The pipe 3 has a flange 3a at its end, and a mandrel 13 is inserted inside to prevent flattening during bending.
このようなパイプ３を固定受はローラ４および起上り式
ローラ５に載せ、曲げローラ２をガイドとして曲げを行
なう。Such a pipe 3 is placed on fixed rollers 4 and rising rollers 5, and bent using the bending rollers 2 as a guide.
このとき、可動枠７は第２図に実線で示すように、曲げ
ローラ２に近い側の受ローラ８ａが上方に位置する姿勢
とし、該受ローラ８ａによりパイプ３の支持がなされて
いる。At this time, the movable frame 7 is in a position where the receiving roller 8a on the side closer to the bending roller 2 is located upward, as shown by the solid line in FIG. 2, and the pipe 3 is supported by the receiving roller 8a.
このとき、フランジ３ａは受ローラ８ａの第２図におけ
る右方に位置している。At this time, the flange 3a is located to the right of the receiving roller 8a in FIG.
このようにしてパイプ３の曲げを行なうと、パイプ３の
フランジ３ａは第２図に鎖線で示すように受ローラ８ａ
より左方に移動するが、可動枠７は受ローラ８ａにフラ
ンジ３ａが当たると同図に鎖線で示すように倒れ、曲げ
作業を阻害することが防止される。When the pipe 3 is bent in this way, the flange 3a of the pipe 3 is bent by the receiving roller 8a as shown by the chain line in FIG.
Although the movable frame 7 moves further to the left, when the flange 3a hits the receiving roller 8a, the movable frame 7 falls down as shown by the chain line in the figure, and the bending work is prevented from being obstructed.
また、可動枠７が倒れることにより受ローラ８ｂが上方
に移動するため、該受ローラ８ｂにより心金１３の支持
がなされ、安定して曲げ加工を行なうことができる。Further, since the receiving roller 8b moves upward when the movable frame 7 falls, the mandrel 13 is supported by the receiving roller 8b, and the bending process can be performed stably.
可動枠７は当初の姿勢において引張りばね１２によりス
トッパｌｌｂに付勢され、また倒れた後も引張ばね１２
により他方のストッパ１１ａへ付勢されるので、安定し
てパイプ３および心金１３の支持が行なえる。The movable frame 7 is urged against the stopper llb by the tension spring 12 in its initial position, and even after falling down, the tension spring 12
Since the second stopper 11a is biased by the second stopper 11a, the pipe 3 and the mandrel 13 can be stably supported.
なお、上記実施例ではパイプ３にフランジ３ａが設けら
れている場合について説明したが、本考案によればパイ
プ３に金物が取付けられている場合にも金物を取り外す
ことなく能率よく曲げを行なうことができる。In the above embodiment, the case where the pipe 3 is provided with the flange 3a has been explained, but according to the present invention, even when a metal fitting is attached to the pipe 3, the bending can be performed efficiently without removing the metal fitting. I can do it.
また、上記実施例は受ローラ８ａ、８ｂのアーム９ａ、
９ｂのなす角度を９０℃としたが、適宜の角度に設定す
ることもできる。Further, in the above embodiment, the arms 9a of the receiving rollers 8a, 8b,
Although the angle formed by the angle 9b is set to 90 degrees, it can also be set to an appropriate angle.
本考案によれば、以上説明したようにパイプにフランジ
