METHOD FOR ROTARY DRAWING OF COMPLEX PROFILE SHELLS Russian patent published in 2009 - IPC B21D22/16 

Abstract RU 2343035 C2

FIELD: technological processes.

SUBSTANCE: in method of rotary drawing blank is installed on profile holder and affected with deforming rollers. Blank profile is formed with separation of deformation between rollers into several sites by means of their radial displacement with equality of radial forces.

EFFECT: provides possibility of complex profile shell rotary drawing, with large length and high diameter difference, at high stability of deformation process.
