Abstract (en)
[origin: WO2018115282A1] A method for producing highly dimensionally accurate sheet-metal components is described, the method comprising: forming a sheet bar into a preformed part (10, 10'), wherein the preformed part (10, 10') has in cross section an excessive developed length, at least in certain regions; calibrating the preformed part (10, 10'), at least in certain regions, to form a calibrated part (50) by using the excessive developed length of the cross section of the preformed part (10, 10'), at least in certain regions, wherein during the calibration the preformed edges of the preformed part (10, 10') are arranged without any form fit, at least in certain regions; and trimming the calibrated part (50), at least in certain regions, after the calibration to produce the sheet-metal component (60). A device for producing highly dimensionally accurate sheet-metal components is also described.
