FIELD: plastic working of metals, possibly manufacture of blanks in the form of bodies of revolution. ^ SUBSTANCE: apparatus includes rolling rolls with curvilinear generatrix. Said rolls are mounted with inclination angle relative to blank axis in bearing assemblies arranged in housing. Apparatus also includes rotating casing with intermediate bearing assemblies engaged with rolling rolls and end cam secured to housing and engaged with intermediate bearing assemblies. Housing is built-up one, it has body or mutually joined bodies and at least two disc chucks kinematically rigidly joined one to other. Said disc chucks supporting roll bearing assemblies are mounted with possibility of rotation in one direction relative to blank axis. ^ EFFECT: high efficiency of rolling blanks in the form of bodies of revolution of any diameters and length values, accurate dimensions and polished surface of blanks. ^ 2 dwg |
