Apparatus for shaping metal bars

Abstract

Abstract IN AN APPARATUS FOR SHAPING METAL BARS, PARTICULARLY CASTINGS IMMEDIATELY SUPPLIED FROM A CONTINUOUS CASTING PLANT, COMPRISING A SERIES OF ROLLING STANDS IN TANDEM ARRANGEMENT CONTAINING PAIRS OF ROLLS, IN WHICH THE ROLLS ARE ARRANGED BY MEANS OF INSERTS, EASY AND ACCURATE ALIGNMENT OF THE ROLL GAPS IN THE DIRECTION OF ROLLING IS ACHIEVED ACCORDING TO THE INVENTION BY PROVIDING FOR EACH ROLL OF A PAIR OFF ROLLS BEING ADJUSTABLE AWAY FROM AND TOWARDS THE ROLL PASS AXIS IN THAT THE TWO INSERTS OF A PAIR WHICH ARE SLIDINGLY ARRANGED WITHIN COMMON VERTICAL OR HORIZONTAL GUIDE MEANS, ARE INTERCONNECTED AND URGED AGAINST INTERPOSED WEDGES BY HYDRAULIC MEANS EXERTING A PRESSURE EXCEEDING THE MAXIMUM ROLL PRESSURE THAT MAY OCCUR, SAID WEDGES BEING INTERCONNECTED TO BE RELATIVELY MOVABLE BY A THREADED SPINDLE SO AS TO CHANGE THE DISTANCE BETWEEN SAID INSERTS AND THEREBY THE ROLL GAP.
