Abstract (en)
[origin: US4355528A] A bending device for metal pipe with and without plastic jacketing has a short cylindrical segment including a circumferential groove which determines the bending radius of the pipe to be bent and a support for holding the pipe to be bent tangentially with respect to the groove. A lever is mounted for concentric pivotable movement about the segment and a pressing block is mounted on the lever for pivotal movement about an axis parallel to the segment axis. The pressing block has a working surface which has an approximately semicircular, concave cross section in a plane disposed parallel to the pivot axis of the pressing block and the segment axis and a concave cross section in a plane disposed perpendicular to those axes.
