Abstract (en)
[origin: EP0032628A2] A workpiece positioning assembly for a punch press of C-shape has a first traverse (5) comprising two rails (7) one secured to each side of the lower limb (3) of the frame, and a second traverse (6) mounted upon the first traverse for horizontal movement in a direction perpendicular to the axis of the second traverse. The second traverse includes only a single rail (14) along which a workpiece support (15) is movable. The punch press may be a turret punch press and include a lower turret (24) the circumference of which has a scalloped configuration so as to receive a die assembly (30) against an arcuate datum surface (41).
