CROSS SEPARATING SKEARS FOR THE ROLLED METAL SHEETS,PART FOR THE THICK SHEETS

摘要

A transverse shear for severing successive sections of heavy metal plate from a length thereof comprises, in addition to the stationary lower blade, a holddown clamp upstream of the blade for pressing the length of plate thereagainst, a movable upper blade which tends to displace the plate to the side toward which the cut progresses, and lateral support elements along the longitudinal edge of the plate at this side, at least one pair of tongs which grip the downstream plate section to be severed along this edge and hold it in position against the tendency of the cut to form a wedge-shaped gap converging toward the aforementioned side. Preferably two such pairs of tongs are provided, both spaced from the cutting location and in spaced relationship to each other.
