Abstract

Einrichtung(1) zum Biegen von Rohrleitungen(2) mit einer Biegeeinheit(4) und einem Biegefinger(15) sowie mit einer Zuführ-Einrichtung(11) und einer Halte- und Verschiebeeinrichtung für die zu biegende Rohrleitung, wobei die Biegeeinheit(4) zweiteilig ausgebildet ist, mit zwei symetrisch angeordneten Biegematritzen(13,14), die jeweils eine nach außen offene, ringförmig verlaufende Nut aufweisen, zwischen welche die Rohrleitung(2) während des Biegevorganges eingelegt ist, und daß der Biegefinger(15) auf einem drehbaren Tragkörper drehbar gelagert ist, wobei die Drehachse des Tragkörpers und des Biegefingers(15) parallel zueinander verlaufen. Means (1) for bending pipes (2) with a bending unit (4) and a bending finger (15) and with a supply device (11) and a holding and displacement device for the pipe to be bent line, said bending unit (4) is formed in two parts, with two symmetrically arranged Biegematritzen (13,14), each having an outwardly open, annular groove extending between which the pipeline (2) is inserted during the bending operation, and that the bending finger (15) rotatable on a is mounted supporting body rotatable, parallel to each other, the axis of rotation of the supporting body and the bending finger (15).
