UNIT FOR AXIALLY FIXING CHOCKS OF ROLLING ROLLS Russian patent published in 1997 - IPC

FIELD: rolled stock production, namely, axial fixing of chocks of rolling rolls. SUBSTANCE: unit includes chocks of upper and lower rolling rolls mounted in port of frame of rolling stand and provided with shoulders, latches of chocks mounted with possibility of horizontal motion in bodies secured to front surface of struts of frame and engaging with said shoulders, hydraulic cylinders for moving latches. Novelty is two parallel bodies mounted in each strut. Latches of chocks are arranged in the above mentioned bodies. Dynamometric members such as magnetoelastic pickups are placed at one side of latches in grooves. At other side opposite relative to pickups stop pins are mounted in struts of stands; between bodies bearing pins are mounted. Latches engage with said pickups and pins. Hydraulic cylinders for moving latches are mounted directly on latches between bodies. Rods of hydraulic cylinders are provided with outer stems resting upon lateral sides of bodies. EFFECT: possibility of measuring and testing axial loads acting upon bearing assemblies of rolling rolls, use of strip rolling process in crossing rolls, enhanced reliability and simplified design of units for fixing roll chocks, increased service life of bearing assemblies and rolling rolls. 2 cl, 7 dwg
