Abstract

The invention relates to a bending beam (1) for a swivel bending machine, wherein the elongated bending beam (1) has an approximately C-shaped beam cross-section (2) and two bending tools (6, 7) whichare opposite one another in relation to a preferably horizontal centre plane (8) and which run facing one another in the longitudinal direction (24) of the bending beam (1), between which a workpiecesection (11) of a workpiece (9) to be bent can be introduced and wherein an angle-measuring system (17) for contactlessly measuring a bending angle (13) is arranged inside (10) the C-shape beam crosssection (2), with which a bending angle (13) can be measured in relation to a reference plane (12) at a workpiece section (11) bent by one of the bending tools (6, 7). The angle-measuring system (17)also comprises: a first angle-measuring unit (18) arranged below the centre plane (8) and having a first measuring region (20) positioned substantially above the centre plane (8); and a second angle-measuring unit (19) arranged above the centre plane (8) and having a second measuring region (21) positioned substantially below the centre plane (8).

Description

technical field [0001] The invention relates to a bending beam for a rotary bending machine according to the preamble of claim 1 and to a bending beam for measuring bends on workpieces in a rotary bending machine according to the preamble of claim 11 angle method. [0002] The subject matter of the invention is referred to below as a bending beam, which alternatively also includes the subject matter referred to as a rotary bending machine or a beam bending machine. Background technique [0003] In order to meet the ever-increasing precision requirements for the bending angles achieved in the bent workpieces in rotary bending machines, there are already embodiments with angle measuring systems with which the forming properties of the workpieces can be detected quantitatively , especially springback, and factor it into the bending process below. A rotary bending machine is known, for example, from JP H 07275952 A1, in which a tactilely operating angle measuring system is int...
