METHOD AND APPARATUS FOR SUBDIVIDING HOT ROLLED ARTICLE CUT PIECES FED FROM ROLLING MILL Russian patent published in 2007 - IPC B21B39/18 B23D25/02 B07C5/02 

FIELD: metallurgical industry branches, namely subdividing pieces fed from rolling mill by suitable for consumer using pieces and non-suitable for using leading and back end portions of rolled articles.

SUBSTANCE: method comprises steps of subdividing each article cut pieces moving along first paths by successive leading end portions, set of intermediate portions and back end portions and feeding said portions to adjacent second paths corresponding to next operation of manufacturing cycle. Said successive portions are fed to second path alternatively while passing of intermediate portions on second paths and shifting of leading an back end portions from second path to third paths is going on. Then leading and back end portions are divided ones from others and second paths are arranged between third paths. System for performing the method includes first and second distributing units and first and second shears. Second distributing unit serves for selective regulation between first positions and it provides shifting of leading and back end portions from second paths to third paths. Second shears are used for further division of end portions along third paths. First and second shears are made with possibility of simultaneous action and with possibility of alternating feed of successive portions to adjacent paths.

EFFECT: lowered shifting degree of suitable and non-suitable for using leading and back end portions moving to shears.
