PIPE BENDING MACHINE Russian patent published in 2022 - IPC B21D7/02 

FIELD: metallurgy.

SUBSTANCE: invention relates to the field of metal forming and can be used in pipe bending. The machine tool contains a frame, on the guides of which there is a longitudinal feed carriage for moving the pipe along its longitudinal axis. On the carriage there is a collet chuck for fixing and clamping the pipe and a mechanism for applying a twisting moment to the pipe. The machine is equipped with an inductor for heating the pipe bend zone by a cross feed carriage with a carrier mounted on a frame with the possibility of transverse reciprocating movement. A gripper for fixing the pipe is mounted on the carrier. The machine is additionally equipped with a carriage with a support element mounted for movement on a guide fixed on the cross-feed carriage. The support element has the possibility of reciprocating movement and contact with the bent section of the pipe during its bending.

EFFECT: expansion of the technological capabilities of the machine is ensured by providing bending of pipes with a small radius.
