DEVICE FOR STATICO-IMPULSE ROLLING WITH EXTERNAL SPRING Russian patent published in 2008 - IPC B24B39/04 

FIELD: technological processes.

SUBSTANCE: device contains striker and wave conductor as rods of same diameter and deforming tool for stock processing with pull, which is installed at the free end of wave conductor by means of cross-beam. Deforming element is made as spiral cylindrical spring, and its coils internal diameter is less than the diameter of processed stock for the value of double pull. The cylindrical spiral spring is installed with the ability to apply static load to it, normally in relation to processed surface, as well as possibility to apply periodical impulse load by means of striker and wave conductor. The cylindrical spiral spring is made under the condition to embrace the processed stock, and its ends are rigidly fixed at the ends of cross-beam.

EFFECT: expands technological capabilities.
