Abstract

The invention relates to a pipe bending device with a curved former attachment (15), which can be used in particular in the installation area for two-handed bending of all pipes encountered there, even in confined spaces. The curved former attachment (15) is attached to the curved former (4) so as to be connected to it in a rotationally fixed manner. The centre line (15.1) of the curved former attachment is then identical to the axis of rotation (5) of the die bore (1.2). The curved former attachment has a shank (15.2), the outer lateral surface (15.3) of which is provided with outer gripping edges (15.4), the dimensions of which correspond to those of gripping elements of known ratchet spanners (18). On the upper side, the shank (15.2) is provided with an upper plate (15.5), in which there is a symmetrically arranged insertion opening (15.6), the dimensions of which correspond to those of an insertion element of a ratchet spanner.
