Abstract

Die Erfindung betrifft ein Verfahren zum Herstellen gewickelter und gebogener Blechteile, bei dem in einem ersten Teilverfahren ein Blechband schrittweise eingefahren wird, wobei es für den Transport und den Stillstand jeweils festgehalten und während des Stillstands signiert, auf Platinenlänge abgeschnitten und die Platine um einen Biegedorn zur Rohbuchse gebogen wird, um anschließend zur Glattbuchse kalibriert zu werden, und bei dem in einem zweiten Teilverfahren die Glattbuchse zur Bundbuchse geformt wird, dadurch gekennzeichnet, daß die beiden Teilverfahren zu einem einzigen, das Fertigprodukt automatisch herstellenden Fertigungsverfahren zusammengefaßt werden, daß in Abhängigkeit von der Ausbildung des Fertigproduktes nur der zur Fertigung zugehörige Teil des Fertigungsverfahrens eingeschaltet und dem jeweiligen Fertigprodukt angepaßt wird und daß der Fertigungsablauf überwacht und bei Abweichungen gestoppt wird, und eine Vorrichtung zum Durchführen des Verfahrens.

Figure 00000001
The invention relates to a method for producing wound and bent sheet metal parts, in which a sheet metal strip is gradually retracted in a first partial process, whereby it is held down for transport and standstill and signed during standstill, cut to board length and the board around a bending mandrel Raw bushing is bent to be subsequently calibrated to the smooth bushing, and in which the smooth bushing is formed into the collar bushing in a second sub-process, characterized in that the two sub-processes are combined into a single manufacturing process which automatically produces the finished product, depending on the Training of the finished product only the part of the manufacturing process associated with the manufacturing process is switched on and adapted to the respective finished product and that the manufacturing process is monitored and stopped in the event of deviations, and a device for carrying out the process.
