Abstract

Die Erfindung betrifft eine Biegevorrichtung für dünnwandige Rohre, die mit kleinem Biegeradius gebogen werden sollen. Die Biegevorrichtung besteht aus einer geraden Rohrführung (1) und einer sich daran anschließenden verschwenkbaren Kernschablone (2) mit Klemmleiste(3) sowie einem biegsamen Dorn (4) mit sich anschließendem Dornschaft (5). Der biegsame Teil wird von einer Schraubenfeder (4a) und einem kugeligen Spannkopf (4b) gebildet. Der Spannkopf (4b), die Schraubenfeder (4a) und der Dornschaft (5) sind über ein inneres Spannseil (6) axial vorgespannt.
