One or more measuring arrangements are positioned on the bending machine, which together include at least one illumination device and in each case at least one image acquisition device. Each measuring arrangement is assigned a different surface portion of the workpiece which lies laterally adjacent to the bending line and extends along the bending line. A light pattern is imaged on the workpiece by means of the at least one illumination device of a respective measuring arrangement onto the assigned surface portion. The light pattern contains a plurality of zones which are arranged side by side along the bending line.

Abstract: An apparatus for measuring a bending angle between two portions of a workpiece in a bending machine includes at least a motion sensor unit provided with a gyroscope sensor, a processing unit connected with the gyroscope sensor and a coupling device for connecting the motion sensor unit with a portion of the workpiece to be bent. During a bending operation of the workpiece the gyroscope sensor measures at least one angular velocity and a related rotation angle of the portion according to an axis and the processing unit receives data from the gyroscope sensor regarding the rotation angle in order to calculate the bending angle as a function of the rotation angle.

Abstract: The invention relates to a bending angle measuring method for a bending machine (1), in particular a bending press or brake press, and the bending machine (1) has a bending tool arrangement (2) with at least one upper (3) and lower tool (4). A sheet to be formed (5) is placed in the bending tool arrangement (2). A light pattern (13) is emitted onto a section by means of a lighting device (11) of a bending angle measuring device (7), the section being a single part and surrounding a sub-region on a lateral surface of the lower tool (4) and of the sheet (5) placed in the bending tool arrangement. The light pattern (13) on the lower tool (4) and on the sheet (5) is detected by an image detecting device (10) of the bending angle measuring device (7), and a bending angle is ascertained from detected light pattern (13) by an analysis module. Furthermore, a transition portion (9) between the lower tool (4) and the sheet (5) is ascertained and, based thereon, a sub-detection region (19) in the detection range (8) of the image detecting device (10) is ascertained. The sub-detection region (19) is detected by the image detecting device (10) and the currently produced bending angle is ascertained while carrying out the bending process.

Abstract: A distortion correction tool corrects distortion in a workpiece held by a fixture. Sensors in the fixture determine the existence, extent, and location of distortions in the workpiece and a controller directs the application of the distortion correction tool to the workpiece based on the information received from the sensors. Particularly, a ram mounted to a quick-change tool head for a robotic arm is used as a distortion correction tool to correct distortions in a workpiece by inducing plastic deformation through use of compressive force, the extent and location of which is determined by a controller based on sensor measurements.

Abstract: Described is a procedure for bending a sheet of sheet metal on a panel bender machine wherein upon bending the sheet of metal sheet a first software (BE) for machine control transmits to a second software (VS) for management of a TV camera (17), positioned in alignment with the bending line, the data relating to the nominal bending angle, the bending length, the distance of the bent edge from the center line of the panel bender and the thickness of the metal sheet. The second software (VS) acquires an image of the bent metal sheet, identifies the spatial position of the straight line corresponding to the bent edge of the sheet of sheet metal and then calculates its geometric coordinates in accordance with a preset referencing system, and supplies to the first software (BE) the value of the angle of the bend performed. The machine control is returned to the first software (BE), which calculates the difference between the angle of the bend actually performed and the angle of the nominal bend and then orders the start of a new bend corresponding to the angular difference, thereby obtaining a bend corresponding to the nominal bend.
