Embodiment Construction

[0041] The invention will now be explained in more detail with reference to the accompanying drawings. However, the exemplary embodiments are merely examples, and are not intended to limit the inventive concepts to certain arrangements. Before describing the present invention in detail, it should be noted that the present invention is not limited to the various components of the apparatus or the various method steps, as these may vary. The terminology used herein is to describe particular embodiments only and is not to be used in a limiting sense. Furthermore, if the singular or indefinite articles are used in the specification or claims, this also refers to a plurality of these elements unless the overall context clearly indicates otherwise.

[0042] According to the invention, both measuring systems for the high tension area and the low tension area are combined for the first time. Preferably, the installation features the use of a single controller C, but in principle a p...

Abstract

In a stretching-bending-straightening system and a method for the actuation thereof, material in strip form is fed to a high-tension region (50) and a low-tension region (52), wherein the low-tensionregion (52) is arranged downstream of the high-tension region (50). A bending-straightening unit is arranged in the high-tension region (50). A measuring system determines first measured values in thehigh-tension region (50). A controller (C) is intended and suitable for determining a deviation of the first measured values from a setpoint value of the bending-straightening result and for determining at least one manipulated variable for the bending-straightening unit in dependence on the determined deviation within a first closed control loop. By additionally providing at least one measuringsystem for determining second measured values in the low-tension region, by having a controller (C) intended and suitable for determining a deviation of the second measured values from the setpoint value of the bending-straightening result and for determining the at least one manipulated variable in dependence on the determined deviation within a second closed control loop, and by providing selecting means that are intended and suitable for selecting the first or second closed control loop for reducing the deviation of the first and / or second measured values from the predetermined or predeterminable setpoint value, a stretching-bending-straightening system and a method for the actuation thereof are designed in such a way that the quality of the strips processed thereby is increased.

Description

[0001] Cross References to Related Applications [0002] This application relates to and claims priority from German patent application 10 2018 101 501.1 filed on 23 January 2018 and German patent application 10 2018 111 627.6 filed on 15 May 2018, the disclosure content of which is hereby incorporated by reference The subject matter of this application is expressly incorporated. technical field [0003] The invention relates to a stretch bending straightening device according to the preamble of claim 1 and a method for actuating it according to the preamble of claim 10 . Background technique [0004] Such as image 3 The stretch bending straightening setup schematically shown in is a setup for minimizing internal stresses in ferrous and non-ferrous metal strips and thus obtaining improved flatness. The term "metal strip" is understood to mean any material in the form of a strip. The term "metallic" per se includes metals and their alloys. The straightening process is per...
