FIELD: plastic working of metal.
SUBSTANCE: sheet bending roll type machine includes frame with struts for mounting upper cylindrical roll with bearing assemblies and two lower rolls. In order to bend helices and coils made of tubes, rigid mutually coupled through bracing members ring halves are mounted on upper and lower rolls. Said ring halves have cone outer surface and cylindrical shape placed on it. Inclination angle of outer cone surface of ring halves is equal to helix lead angle. Cylindrical shape provides desired lead angle of helix.
EFFECT: enlarged manufacturing possibilities of roll type sheet bending machine.
