Bending machine with a machine bed including a workpiece table with a workpiece support surface and an upper tool which is linearly movable mounted to the machine bed along a movement axis and which has a bottom edge arranged adjacent to the workpiece support surface. The lower edge and the movement axis define a movement plane which separates a handling space from a workpiece receiving space, in which a first optical safety device is arranged in the handling space and a second optical safety device is arranged in the workpiece receiving space, and with a safety controller to process sensor signals from the optical safety devices and for switching off a drive associated with the upper tool. The safety controller provides a first operating mode, in which only the first sensor signals are processed, and a second operating mode, in which only the second sensor signals are processed.
A bending machine having a machine bed with a workpiece table which has a workpiece supporting surface, and with an upper tool mounted on the machine bed for linear movement along a movement axis, which upper tool has a lower edge arranged adjacent to the workpiece support surface, the lower edge and the movement axis defining a movement plane in which the lower edge can move between an open position for the upper tool and a closed position for the upper tool, the movement plane separating a handling space, which extends from the upper tool in the direction of a front edge of the workpiece support surface, from a workpiece receiving space, which extends from the upper tool to a rear edge of the workpiece support surface support surface and wherein a first optical safety device is arranged in the handling space and a second optical safety device is arranged in the workpiece receiving space, and with a safety controller which processes first sensor signals of the first optical safety device and second sensor signals of the second optical safety device and is set up for switching off a drive associated with the upper tool dependent on the first sensor signals and/or dependent on the second sensor signals, wherein the safety controller is switchable between a first operating mode, in which only the first sensor signals are processed, and a second operating mode, in which only the second sensor signals are processed, and wherein the upper tool is a workpiece holder for securing a workpiece to the workpiece table, and wherein a folding beam extending along the front edge of the workpiece supporting surface is attached to the workpiece table such that it can pivot, with a pivot axis of the folding beam being aligned parallel to the lower edge of the upper tool and to the front edge of the workpiece supporting surface.
