Claims (1)
に取付けた２連の押えローラと、管曲げ外側に配置した
外側ローラとをリンクアーム等を介して機械的に結合す
るとともに、前記外側ローラの位置を決めるロッドを有
し、管曲げ内側部の加工開始点とこの点に隣接した加工
後の点の２箇所に押圧力を与えるよう構成したことを特
徴とするパイプペンタ用ローラマ゛ンドレル。The pipe is bent by mechanically connecting two presser rollers, one of which is fixed to the mandrel and the other movably mounted on the inside of the pipe, and an outer roller placed on the outside of the pipe bending via a link arm, etc. A roller mandrel for a pipe pentameter, characterized in that it has a rod that determines the position of the roller and is configured to apply pressing force to two points: a processing start point on the inner side of the pipe bending and a post-processing point adjacent to this point. .
