Round bending device and method for reshaping sheet sections into round objects, in particular sleeves, by bending around the peripheral surface of a cylindrical bending core

摘要

the invention relates to a rundbiegevorrichtung the forming of bandabschnitten (4) to rundku00f6rpern, particularly casings, by bending the umfangsflu00e4che a round biegekerns (2), a full biegekern (2) and several of the biegekern (2) around the biegestempel (12, 15, 18, 21, 2 4, 27)in the direction of the umfangsflu00e4che biegekerns (2) in a particular sequence in a umformstellung to biegebeaufschlagung biegekern (2) each of the previously introduced bandabschnitts (4) movements and the release of the bandabschnitts (4) after the adjustment of the rundku00f6rper back from biegek two (2) in a freigabestellung zuru00fcckziehbar, with the biegekern (2) is set upduring a umformprozesses at least two different defined umfangskonturen consecutively to accept.
