Plate bending machine
First Claim
1. A plate bending machine comprising:
- a punch and a die movable toward and away from each other for bending a workpiece in cooperation with each other, said punch having a bending edge extending along a line;
a first support means for supporting the punch and the die, the first support means being rotatable about a bending axis coincident with the bending edge of the punch;
a second support means for supporting the first support means, the second support means being pivotable about an axis intersecting the bending axis; and
a workpiece support means for supporting the workpiece between the punch and the die with the plane of the workpiece extending vertically and perpendicularly to the pivoting axis of the second support means and said plane of the workpiece extending so as to contain the bending axis.

Abstract
The machine includes a U-shaped pincer (12) with a pair of arms (14, 16) which carry a V-sectioned linear punch (P) and a V-sectioned linear die (D) respectively. The punch (P) is fixed and the die (D) is movable. The U-shaped pincer (12) is mounted so that it can rotate both about a bending axis (V) coincident with the edge of the punch (P) and about a horizontal pivoting axis (O) which intersects the bending axis (V). A clamp (10) is adapted to grip an upper edge of a piece (W) of sheet metal so that a region thereof to be bent lies in a vertical suspension plane (B) lying between the arms (14, 16) of the U-shaped pincer (12) and containing the bending axis (V). The U-shaped pincer (12) and the clamp (10) are capable of relative movement both in a vertical direction (Z) and in a horizontal direction (X) perpendicular to the horizontal pivoting axis (O).
