Abstract

　加工対象である金属管の一部を環状に加熱する加熱手段と、加熱手段に向け金属管を推進させる推進手段と、金属管を把持すると共に支軸を中心として回動可能なクランプアームを含み、クランプアームによって加熱手段による金属管の加熱部の前方部分を把持すると共にこの把持点を推進手段による金属管の推進に伴い支軸を中心として旋回させ、これにより金属管に曲げモーメントを加える案内手段と、推進手段による金属管の推進方向とは反対方向への力である引戻力を、支軸を支点としてクランプアームを介し金属管に加えることにより金属管に圧縮力を作用させる圧縮手段とを備える金属管の曲げ加工装置で、前記引戻力の印加点と支軸との距離がクランプアームによる金属管の把持点と支軸との距離より大きくなるように圧縮手段を配置する。金属管の圧縮曲げ加工における圧縮駆動力の増大を招くことなく減肉量を一層低減することが出来る。
