The invention relates to a bending press () and/or a loading device () for loading a bending press () with bending tools (), comprising:

Bending press and/or loading device

The invention relates to a method for bending a workpiece () of sheet metal, whereby a deformation region (), in particular a strip-shaped region, on the workpiece () containing the bent edge to be produced () is heated before and/or during the bending process to a deforming temperature below the fusion temperature of the metal to increase deformability locally. In order to reduce undesirable deformation due to shrinkage stress, the workpiece () is heated before and/or during and/or after the bending operation in at least one heating zone () that is different from the deformation region () by means of the application of energy from outside the workpiece () starting from an initial temperature to a processing temperature below the fusion temperature of the metal.

Method for bending a workpiece

A method for guiding and distributing high-energy radiation, in particular laser radiation, in the tool base body of a bending die, in particular a V-shaped die, includes a bending recess in the tool base body and a beam exit opening arranged therein for locally heating a workpiece bearing against a contact surface of the bending die by introducing high-energy radiation from a radiation source arranged outside the tool base body into the tool base body through a beam entry opening and high-energy radiation is discharged to the bending recess through the beam exit opening. At least one concentrated high-energy radiation beam is introduced into the tool base body through at least one beam entry opening and is at least partially deflected by at least one beam affecting arrangement in the tool base body, expanded and guided through the radiation exit opening onto the workpiece.

The one or more planar fanned beams (, . . . ) are produced by a number of optionally activatable radiation sources (, . . . ) which are arranged within the die arrangement () along the bending recess () or are caused by the distribution of a concentrated radiation beam () that is introduced from a radiation source () outside the bending dies (, . . . ) via a number of beam affecting arrangements (, . . . ) within the bending dies (, . . . ) and the exiting radiation () is thereby adjusted to the bending length () of the workpiece to be bent () via the number of planar fanned beams (, . . . ).

Device and method for bending a workpiece

The invention relates to a bending die (), particularly a V-shaped die (), comprising a tool base body () with a contact surface () for contacting the workpiece () to be bent by a bending punch (), a groove-shaped bending recess () in the contact surface () and at least one beam exit opening () in the bending recess () and extending along thereof, which is configured to discharge high-energy radiation () onto a workpiece () bearing against the contact surface () in order to heat the deformation zone of the workpiece (). An arrangement of diode laser bars () is fixed in the interior of the tool base body () for producing the radiation (). Said diode laser bars () are arranged at least approximately uniformly along the longitudinal direction () of the bending recess () behind the beam exit opening () in the tool base body ().

Bending machine

A gripping device for a manipulation system, particularly a robot, for receiving workpieces and feeding them from a readied stack of the workpieces to a manufacturing plant such as a metal sheet folding machine, punching press, welding plant, etc. The device has a gripper head fitted with gripping means such as suction cups, magnets, tongs, etc., and a detection system for detecting characteristics of the workpiece gripped by the gripping means. A pulse emitter excites vibrations in the workpiece and the vibration spectrum of the workpiece is compared to reference vibration data to determine characteristics of the gripped workpiece, such as whether two or more workpieces are stuck together, or whether the workpiece is the correct workpiece.

For each drive of a drive arrangement, the actual pressing force is detected for the displaceable press beam during a bending process for the workpiece and a relative position of the pressing tool or tools by reference to the longitudinal extension of the press beams is determined on the basis of a force ratio. Different displacement paths of the drives and the displaceable press beam at the respective force-application point of the drive are then determined in an evaluation and/or computer unit, which is provided with a data memory for production and machine data, and corresponding control signals for the drive system are generated in the control unit and actuator elements of the drives are displaced by the displacement paths determined for each drive.
