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 pressing beams (13, 16), at least one bending tool (4), such as a bending punch (5) and a bending die (6), which is connected to the pressing beams (13, 16), and at least one angle-measuring device (46) for determining an angular position of at least one limb (35, 36), formed by a bending operation, of the workpiece (2) with respect to a reference plane (41, 42). In this case, the angle-measuring device (46) comprises at least one inclination sensor (39) which has a reference surface (40) and the inclination sensor (39) having the reference surface (40) is supported by the angle-measuring device (46) so as to be placeable against a surface section of at least one of the limbs (35, 36) of the workpiece (2).

Description

technical field

[0001] The invention relates to a manufacturing plant comprising an angle detection device, in particular for bending workpieces to be manufactured from sheet metal, as described in claims 1 and 12, and to a method for determining at least one angle formed by the bending process. method of the angular position of the outrigger with respect to the reference plane. Background technique

[0002] A device for measuring angles on a workpiece is known from EP 0 637 371 B1 or from DE 694 11 821 T2, in which a sensor is arranged in the base body of the bending tool which is movable relative to the base body. Each of the sensors has a contact device for contacting the corresponding section of the workpiece during the measurement, wherein the sensors are kinematically completely independent of one another. Furthermore, the device has a separate pressure device in order to bring the contact device of the sensor into contact with the corresponding section of the workpie...
