Abstract: An elongated bending beam for a swivel bending machine has an approximately C-shaped beam cross section and two bending tools, which are opposite one another relative to a preferably horizontal central plane, and which run facing one another in the longitudinal direction of the bending beam, between which a workpiece portion of a workpiece to be bent can be introduced. An angle-measuring system for contactlessly measuring a bending angle is arranged inside the C-shape beam cross section, with which a bending angle can be measured relative to a reference plane at a workpiece section bent by one of the bending tools. The angle-measuring system also includes a first angle-measuring unit arranged below the central plane and having a first measuring region positioned substantially above the central plane, and a second angle-measuring unit arranged above the central plane and having a second measuring region positioned substantially below the central plane.

Abstract: A method for transferring a workpiece from a first manipulator to a second manipulator by means of a manipulation system in a bending installation having at least one bending machine is provided. Each manipulator comprises first, second, and third manipulator arms, each of which is pivotable about second axes, third axes, and fourth axes and exclusively in a parallel orientation with respect to a first axis of a guide arrangement. The workpiece is grasped by a holding arrangement of the first manipulator. The third manipulator arms are oriented to be opposite and to project towards one another, and the same workpiece is grasped by a holding arrangement of the second manipulator and subsequently released from the holding arrangement of the first manipulator for the direct transfer process. The invention furthermore relates to a manipulation system and a bending installation equipped therewith.

Abstract: A production installation for producing workpieces from sheet metal by forming in a bending operation includes a bending machine and a clamping tool having at least one lower clamping jaw and an upper clamping jaw set including first upper clamping jaws and a second upper clamping jaw. The second upper clamping jaw has a clamping jaw part at each of the two second upper clamping jaw end sections, the clamping jaw parts being movable from a working to a pull-out position. At least one first upper clamping jaw is arranged on both sides of the second upper clamping jaw. The first upper clamping jaws have a first horn at each of the first end regions of the first upper clamping jaws facing away from the second upper clamping jaw. A method adapts a total length of a bending edge of a clamping jaw set of this production installation.

Abstract: A measurement device (100 . . . 103) for measuring the thickness (d) of a plate-shaped object (7) is indicated, which comprises a first measurement sensor (21 . . . 23) for being set onto a first surface (9) of the plate-shaped object (7) and a second to fourth measurement sensor (31 . . . 53) for being set onto a second surface (10), opposite to the first surface (9) of the plate-shaped object (7). Furthermore, the measurement device (100 . . . 103) comprises means for calculating the thickness (d) of the plate-shaped object (7), using the positions (81 . . . 84) at which the measurement sensors (21 . . . 53) touch the plate-shaped object (7). Furthermore, a measurement method for measuring the thickness (d) of a plate-shaped object (7) is also indicated.
