Abstract

Es hat sich gezeigt, dass bei Rundbiegemaschinen mit langen Walzen auch dann Ungenauigkeiten des Biegeproduktes entstehen, wenn die Gleichlaufsteuerung der Seitenwalzen (3) fehlerfrei arbeitet. Es wurde nun gefunden, dass das eine Folge der unsymmetrischen Durchbiegung der Oberwalze (1) ist und dass sich dieser Fehler durch ein Korrekturglied (30) in der Gleichlaufsteuerung beheben lässt, wobei dieses Korrek­ turglied ein entsprechendes Schiefstellen der Seitenwalze (3) zu bewirken hat. Dieses Korrekturglied kann ein zwischen das Gleichlaufventil (31) und das Lager (20) der Gleichlaufwelle (9) eingesetztes Element (30) sein, dessen wirksame Länge proportional zu dem auf die Unterwalze einwirkenden Druck p verändert wird. It has been shown that with bending machines with long rollers then inaccuracies of the bending product arise when the synchronization of the side rollers (3) works flawlessly. It has now been found that one As a result of the asymmetrical deflection of the top roller (1) and that this error is corrected by a correction element (30) in the synchronization control can be corrected, this correct a corresponding misalignment of the side roller (3) has to effect. This correction element can be one between that Synchronous valve (31) and the bearing (20) of the synchronous shaft (9) inserted element (30), its effective length proportional to the pressure p acting on the lower roller is changed.
