Definitions

  • this nominal force value is influenced depending on the position of the head roller and the current tube geometry.
  • an expander tool is inserted, which consists of a tool head 10 with radially expandable segments 9.
  • the tool head 10 is arranged on a pull rod 11 which radially spreads the segments 9 by means of an axial movement via the wedge 14 located between the pull rod 11 and the segments 9 and thus expands the tube.
  • the expander or tube axis is denoted by 3.

Abstract

L'invention concerne un procédé et un dispositif pour mettre en oeuvre ledit procédé, comportant un outil d'expansion pouvant être introduit dans un tube. Cet outil est constitué d'au moins une tête située sur une tige de traction, la tête comportant des segments pouvant être écartés dans une direction radiale, et un rouleau agencé sur celle-ci et pouvant s'adapter dans la position radiale au diamètre de tube à calibrer pour soutenir l'outil d'expansion sur le tube, et un rouleau de support qui soutient le tube à calibrer. Le rouleau de tête est équipé d'un dispositif de mesure pour enregistrer la force de soutien agissant sur le rouleau de tête pendant l'expansion. En outre, l'invention concerne une unité d'évaluation et de surveillance des valeurs de mesure et une unité de signal indiquant un écart par rapport à des seuils de tolérance prédéfinis.
