摘要

A rotary shearing machine for cropping ends of bars or other section and scrapping of bars or other sections rolled in rolling mills comprising two parallel overlying shafts each carrying a pair of rotary disc knives for cropping the front end and  the rear ends of  the said bars or other sections and a separate pair of straight knife for scraping the bars or other sections which are not suitable for further operations, a drive mechanism for rotating the said shafts, a deviating pipe passing through at least one pair of guide rolls and held by a pivoted clamp, a pneumatic cylinder having an actuating rod for  adjusting the position of the said deviating pipe relative to either of the said pairs of knives for cropping the front ends or the rear ends of the bars or other sections or the pair of straight knives for scrapping the bars or other sections.
