摘要： 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.

摘要： 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).
