SPINNER FOR STATIC-DYNAMIC BREACHING Russian patent published in 2011 - IPC B21D22/16 

FIELD: process engineering.

SUBSTANCE: invention relates to metal forming, particularly, to rotary drawing and shell spinning. Spinner comprises waveguide and striker acting thereon and coupled with mechanical pulse generator. Note here that said waveguide is made up of spinning ring embracing the billet and having inner rounded working surface and needled part made up of metal wire frieze bundles that allows adjusting stiffness, and with ID smaller than that of said rounded working surface by double interference. Note also that spinning ring moves inside the case in radial bearings arranged on ring periphery to transmit to said ring straining force with static and dynamic components.

EFFECT: expanded process performances, higher quality and efficiency.
