DEFORMING STAND Russian patent published in 2000 - IPC

FIELD: plastic metal working, possibly in shops for rolling and drawing. SUBSTANCE: deforming stand includes housing in which chocks are mounted for supporting movable roller type roll and deforming member. Stand includes in addition at least one additional deforming member forming roll pass together with movable roll and above mentioned deforming member. Additional deforming member is in the form of movable or stationary roll or it is in the form of stationary insert. At rolling process zones of metal surface being in contact with stationary deforming members are braked and in the result elongation of metallic billet is reduced. Zones of metal surface being in contact with movable deforming members are accelerated and in the result their elongation is increased. Therefore in roll pass of stand non-uniform redistribution of elongation along cross section of deformed billet is controlled. EFFECT: enlarged using range of stand due to possibility for rolling symmetrical and non-symmetrical bar products. 4 cl, 5 dwg
