DEVICE FOR STATIC-PULSE ROLLING OF SCREWS Russian patent published in 2008 - IPC B24B39/04 

FIELD: technological processes.

SUBSTANCE: device consists of two discs with central openings, deformation elements, upper and lower levers, two balancing levers and a load spring and hydraulic hammer fixed at the free end of the lower lever. One of the discs has an inverted-L shape for holding the device on the machine slide, while the other disc is rigidly fixed to the butt-end of the first disc by spacers and screws. The deformation elements are movably installed between the above mentioned discs. The upper and lower levers movably installed on over the other, are located between the discs and are hinged to each other by an axle, installed at one end of the above mentioned levers. One of the balancing levers is rigidly fixed on one end of the lever, and the other is hinged to the other lever. A bearing is installed between the discs. The hydraulic hammer is made under the condition providing for pulse effect on the free end of the upper lever. The deformation elements are in form of deformation roller, made with provision for free rotation on their axes and mounted in pairs on the two given balancing levers. The lower lever in the middle is supported by the bearing collar.

EFFECT: more technological capabilities, lower cost price; increased output and improved quality of processed objects.
