DEVICE FOR MANUFACTURING OF LONG-LENGTH PIPES WITH HELICAL CORRUGATIONS Russian patent published in 2009 - IPC B21D15/04 

FIELD: technological processes.

SUBSTANCE: invention may be used in metal plastic working in manufacturing of pipes with helical corrugations. On device stand head is installed with shape-generating rollers arranged in it around device axis and at the angle to it with the possibility of rotation around their axes, as well as unit of working displacement of rectilinear section of pipe along device axis, which is arranged with the possibility of rotation around specified axis. Unit of working displacement of rectilinear section of pipe along device axis is arranged in the form of two platforms fixed on stand at different sides of head with rotation drives around device axis, on every of which unit of cylindrical drum fixation is installed with drives of rotation around its axis, displacement along specified axis and displacement perpendicular to device axis. Besides every cylindrical drum is arranged with the possibility of fixation of pipe end on it and its winding on drum and unwinding from it. Moreover, axes of drum and device are arranged as crossing and perpendicular to each other.

EFFECT: expansion of technological resources.
