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.The invention relates to a method and an apparatus for producing slotted tubes (4; 104) from sheet metal plates (3), in particular thick metal sheets, wherein a metal sheet is fed to a tube forming press (1) in which it rests on a lower tool (6) Can be raised and lowered upper tool (9) by applying a bending force gradually to the laterally seam welding with a gap (11; 111) opposite longitudinal edges having slot tube (4; 104) is formed.

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.

Figure imgaf001
In order to achieve as far as possible circular slotted tubes (104) with a narrow slit or slit (111), a slotted tube with a non-circular preform (13) is first produced, by means of at least one of the longitudinal axis of the sheet metal sheet being progressively molded into the slab (3) submerged upper tool (9) predetermined center each left and right on the inside of the metal sheet (3) acting bending step is made with respect to the other Biefahrens lower indentation, and that thereafter by applying an externally on the non-circular preform (13) itself The finished slotted tube (104) is specifically formed in each case in the closing force (F) which previously has an effect on both sides of the middle of the slightly shaped regions (12a, 12b).
