Abstract: A bending machine has a bottom platen (12) with a bottom platen tool and a top platen (14) with a top platen tool movable with respect to one another to clamp a workpiece, as well as a bending platen (30) that can swivel around a swivelling axis (36) and has bending platen tool segments (44) provided each with a compression surface segment. A bending platen compression surface which presses the workpiece during bending can be composed of the compression surface segments. In order to improve such a bending machine so that the width of the bending platen compression surface may be easily altered, at least one bending platen tool segment is adjustable. In the adjustable bending platen tool segment, the compression surface segment can be moved from an active position in which it adds to the compression surface of the bending platen tool to an inactive position in which it is without effect during a bending operation.

Abstract: An assembly line for producing steel coffers (2) from sheet metal plates (1) for ceiling and/or wall constructions, in particular for completing the interior or for building the superstructure of ships, for transportable and movable buildings, for halls, hotels and the like, has a cutting and/or stamping station (3), a bending press (4) with an associated manipulator (5) and associated ball transfer table (6), and a soldering station (7), as well as at least one running carriage (8) capable of travelling back and forth below these stations (3, 5, 7) and designed as an underfloor vehicle, an underfloor trolley or the like. The bending press (4) is combined with a manipulator (5) designed as a semiportal crane movable with respect to the press (4) and having an equally movable, vertically movable gripper rotatable around the vertical axis, with which the sheet metal plates (1) are moved to the required positions in the bending press (4). The bending press (4) has a holding-down clamp capable of being swivelled by an eccentric drive in order to compensate for different thicknesses of the sheet metal plates.

Abstract: A process for the two-directional bending of sheet metal comprises the following stages: The bending cheek of a swivel press is laid on a first side of a sheet metal section which is bent about a predetermined angle in a first direction of rotation; the bending cheek is then withdrawn from the bent sheet in a first direction of movement prependicularly to its pivoting axis and pivoted further in the first direction of rotation until it lies against the second side of the sheet opposite the first; the bending cheek is shifted in a second direction perpendicularly to the first; after the bent sheet has been suitably moved between the lower and upper cheeks of the bending machine, the bending cheek is laid against the second side of the sheet, which is bent about a predetermined angle by pivoting the bending cheek in a second direction of rotation opposite that of the first. In the bending machine for implementing this process, the bending cheek is fitted so that it can perform both mutually perpendicular movements in the first and second directions of travel.
