Abstract: The invention relates to a lower tool (1) having a longitudinal-offset measuring device (2), which lower tool (1) is part of a bending tool arrangement for use in a bending press. The lower tool (1) has a tool body (3) having a longitudinal extension (4), in which longitudinal extension (4) a bending recess (5) is provided. The bending recess (5) extends from an upper flat side (6) of the tool body (3) into the latter and is formed at least by two contact surfaces (7). The transition from the upper flat side (6) into the bending recess (5) forms a contact edge (8), which contact edge (8) forms a contact line (9) in the longitudinal extension (4). A sensor (10) for determining a longitudinal offset (18) is arranged in the region of the contact line (9), wherein a sensing portion (11) of the sensor (10) is oriented in the direction of a metal sheet (16) to be bent.

Abstract: The invention relates to a production plant (1), in particular for folding workpieces (2) to be produced from sheet metal, comprising a bending press (3), in particular a press brake, having a press beam (13, 16), at least one bending tool (4), such as a bending punch (5) and bending die (6), which is connected to the press beam (13, 16), and at least one angle-measuring device (46) for determining an angular position of at least one limb (35, 36) of the workpiece (2) formed by a bending operation relative to a reference plane (41, 42). The angle-measuring device (46) comprises at least one inclination sensor (39) having a reference surface (40) and the inclination sensor (39) is mounted by the angle-measuring device (46) so that it can be placed with the reference surface (40) lying in contact with a surface portion of at least one of the limbs (35, 36) of the workpiece (2).

Abstract: The invention relates to a rear stop unit (7) with a stop and/or gripping and/or measuring element (10) for positioning a sheet (3) to be machined on a bending press. The stop and/or gripping and/or measuring element (10) is arranged on an adjustable bearing arm (13) by means of a pivot joint (12). The bearing arm (13) is connected to a guide rail (20) by means of an additional pivot joint (18) via a guide element (19). The rear stop unit (7) further comprises a support arm (21) which is connected to the bearing arm (13) via a joint (22) and to an additional guide element (24) via a rigid connection, and the support arm is connected to the guide rail (20) via the additional guide element. Furthermore, the joint (22) is designed as a rotational/prismatic joint. The position of the bearing arm (13) can thereby be adjusted by moving the support arm (21) in a linear manner along a guide direction (11) specified by the guide rail (20).

Abstract: The invention relates to a machine controller comprising a sensor module (4), an evaluation module (9) and a control module (5), and the sensor module (4) has a convertor which converts a mechanical variable acting on the sensor module (4) into a proportional electric characteristic variable, and the evaluation module (9) is connected via a first signal connection (8) to the sensor module (4) and via a second signal connection (11) to the control module (5). The evaluation module (9) generates a signal profile from the detected electric signal by means of an analysis of potential and/or change, which is compared with at least one reference signal profile stored in a memory means of the evaluation module (9) by means of a comparison module of the evaluation module (9), from which the control signal is generated. Furthermore, at least one of the two signal connections (8, 11) is based on a wireless design.

Abstract: The invention describes a production machine (1), in particular an edging press (2), preferably for shaping sheet metal parts (3) for making housing parts, sections (4), etc, with a machine frame (5) having C-shaped supporting side plates (6, 7) and at least one wall part (13) spacing the supporting side walls (6, 7) at a distance (11) apart from one another and permanently joined thereto. Mounted on the machine frame (5) so as to be non-displaceable is a press beam (15) on which a bending tool (36) can be mounted. Lying opposite it is another press beam (16), on which a bending tool (37) can also be mounted, displaceable in a guide arrangement (30) of the machine frame (5) by means of a drive arrangement (27). An actuator drive (25, 26) drivingly connected to the displaceable press beam (16) is preferably provided respectively on opposing side faces (22, 23) of each of the supporting side walls (6, 7).
