FIELD: mechanics.
SUBSTANCE: device includes lead screw kinematically connected through worm reduction gearbox to cam interacting with limit stop fixed on unmovable part of device. At that, body of worm reduction gearbox is installed with possibility of axial movement along guides; cam is located on axis of worm gear wheel, and force closure of cam and limit stop is performed with hydraulic cylinder. For enlarging process capabilities, it is equipped with intermediate shaft installed in body of worm reduction gearbox. One end of intermediate shaft is rigidly connected through sleeve to lead screw, and on its other end, outside the body of worm reduction gearbox, gear transmission interacting with worm is arranged.
EFFECT: enlarging process capabilities.
