METHOD OF STATIC PULSE BURNISHING Russian patent published in 2011 - IPC B21D22/16 

FIELD: process engineering.

SUBSTANCE: invention relates to metal forming, particularly, to rotary drawing of cylindrical shells, hollow articles and, to static pulse spinning. Spinning tool comprises waveguide and hammer connected with generator of mechanical pulses. Said spinning tool is fed in lengthwise and crosswise directions to drive into billet, while the latter is revolved. Note here that wave guides embraces spinning ring workpiece with rounded working surface and needle part made up of metal wire frieze bundles to allow adjustment of stiffness and with ID smaller than diametre of inner rounded surface by double interference. Note also that spinning ring runs in radial bearings arranged on ring periphery to impart thereto deforming force with static and dynamic components.

EFFECT: expanded processing performances, higher quality and efficiency.
