Abstract

The pipe bending device has a straight pipe guide (1) leading to a relatively pivoted bending block (2) provided with a clamp rail (3) and a flexible thorn (4) with a thorn shaft (5) inserted in the end of the pipe. The flexible thorn is provided by a coil spring (4a) and a spherical clamp head (4b), with an internal tensioning cable (6) used for axially tensioning the clamp head, the coil spring and the thorn shaft.
