TUBES WITH HELICAL CORRUGATIONS PRODUCTION APPARATUS Russian patent published in 2006 - IPC B21D15/04

Abstract RU 2280523 C1

FIELD: plastic working of metals, production of tubes with helical corrugations.

SUBSTANCE: apparatus includes housing; heads mounted in housing and carrying shaping rollers. Shaping rollers are mounted in heads around axis of apparatus and they are inclined relative to it. Shaping rollers are mounted with possibility of rotation around their own axes. Apparatus also includes unit for working motion of tube in the form of two clamps provided with drive members for moving clamps along axis of apparatus and for rotating them around said axis. Each head includes face chuck supporting mechanism for radial motion and rotation of shaping rollers relative to axis of apparatus.

EFFECT: enlarged manufacturing possibilities, enhanced efficiency of apparatus, improved quality of tubes.
