METHOD OF STATIC-IMPULSE ROLLING Russian patent published in 2009 - IPC B24B39/04 

FIELD: mechanics.

SUBSTANCE: rotary motion is imparted to blank, and feed motion is imparted along processed blank to device. Device comprises two disks with central holes, one of which has L-shaped holder, and other disk is rigidly fixed to the end of the first disk with the help of spacer bushings and screws, and deforming elements that are movably installed between disks. Deforming elements are arranged on the form of steel helical cylindrical springs turns from circular wire, which are movably installed on two levers that embrace the processed blank. At that every spring freely rotates in axes and rests on at least two press rollers, which are installed in bearings of covers fixed on the ends of specified levers. Levers are hingedly connected to each other with the help of axis installed at one end of levers, and are movably installed horizontally between disks one above another. With its middle lower lever rests on external ring of bearing installed between disks and sitting on axis. On the other free end of lower lever there are hydraulic hammer that affects free end of upper lever in pulse manner and loading spring.

EFFECT: higher efficiency of processing, accuracy and quality of processing.
