Seam folding device for mechanical press brake to generate hundred and eighty degree folding on pre-edged plate shaped workpiece, has gap between side surfaces of dies to receive wedge extension over distance measured perpendicular to plane

摘要

The device (1) has a fold die (5) arranged adjacent to a bending die (3) and forming a support surface (33) in a plane (23) extending perpendicular to adjusting direction of a bending punch (4). A tool retainer (7) for the dies is adjustably arranged on an upper side of a table bar (9) in a direction perpendicular to a bending plane (22). A gap (27) is formed between side surfaces (6, 30) of the dies for receiving a wedge extension (26) over a distance measured perpendicular to a bending plane. The side surfaces face each other.
