HIGH SPEED CUTTING METHOD FOR ROLLED SECTIONS IN CONTINUOUS ADVANCEMENT AND CUTTING GROUP THOUGHT FOR WORKING BY SUCH METHOD

摘要

High speed cutting method for rolled sections in continuous advancement of the type in which is substantially provided: a flying shear for the bars cutting with always rotating cutters; shifting means which guide the bar to be cut from a position sideways of said cutting rotating cutters; through said cutters for carrying out the cutting, and sensor means of the bar to be cut; comprising means for detecting the rolled section (1, 11) advancement parameters and automatic means for adjusting the cutters (24) speed to the speed and position of the advancing rolled section (1-11, L1), associated to the control of the respective shifter (23) movement. Thus making possible correcting the errors in the bars cutting length.
