Abstract

Die Erfindung betrifft ein Verfahren und eine Vorrichtung zum Herstellen von Schlitzrohren (4; 104) aus Blechtafeln (3), insbesondere dicken Blechtafeln, wobei eine Blechtafel einer Rohrformpresse (1) zugeführt wird, in der sie auf einem Unterwerkzeug (6) aufliegend von einem heb- und senkbaren Oberwerkzeug (9) durch Aufbringung einer Biegekraft schrittweise zu dem sich zu einer späteren Längsnahtschweißung mit einem Spalt (11; 111) gegenüberliegende Längskanten aufweisenden Schlitzrohr (4; 104) eingeformt wird.
Damit sich weitestgehend kreisrunde Schlitzrohre (104) mit einem engen Schlitz bzw. Spalt (111) erreichen lassen, wird zunächst ein Schlitzrohr mit einer unrunden Vorform (13) erzeugt, indem zumindest in einem bezogen auf die von der Längsachse des in die fortschreitend eingeformte Blechtafel (3) eintauchenden Oberwerkzeugs (9) vorgegebenen Mitte jeweils links und rechts an der Innenseite der Blechtafel (3) wirkenden Biegeschritt eine gegenüber den anderen Biegeschritten geringere Einformung vorgenommen wird, und dass danach durch Aufbringung einer von außen auf die unrunde Vorform (13) sich jeweils gezielt in den zuvor beidseitig der Mitte geringer eingeformten Bereichen (12a, 12b) auswirkenden Zudrückkraft (F) das fertige Schlitzrohr (104) ausgeformt wird.
