ABSTRACT:
An adjustable angular shearing device (10) in accordance with the invention is adapted to transversely shear sheet material from a continuous strip in a punch press. The device (10) has an upper punch (24) which coacts wtih a lower die (28) to shear sheet material passing between them. The punch (24) comprises a pair of members (32, 34) which coact with a pair of corresponding members (74, 76) on a lower die (28). The members rotate about aligned posts (26, 30) at the vertex of an angle. The rotation of the members about each respective post is selectively adjustable. A chevron-shaped part can be stamped from a continuous strip of sheet material by two successive stamps of the punch press.
