Description

Es ist bekannt, Rohrstutzen aus Blech in der Weist mittels einer Ziehpresse herzustellen, daß ein mit einem kreisförmigen Ausschnitt versehenes Blech im warmen Zustand mittels einer Ziehpresse durch Biegen und Strecken in die Form des Rohrstutzens gebracht wird.It is known, pipe socket made of sheet metal in the Weist by means of a drawing press produce that a sheet metal provided with a circular cutout in the warm Condition by means of a drawing press by bending and stretching into the shape of the pipe socket is brought.

Die Erfindung bezieht sich auf die Herstellung von Vorschweißflanschen und ähnlichen Werkstücken, und zwar insbesondere solchen mit hohem Stutzen. Nach der Erfindung erfolgt die Herstellung der Flanschen mittels Pressen so, .daß eine Blechscheibe zunächst gekümpelt, gelocht und dann durch Biegen und Strecken in die gewünschte Form gebracht wird.The invention relates to the manufacture of welding neck flanges and similar workpieces, especially those with high necks. To the invention, the production of the flanges by means of pressing so, .that a Sheet metal disc first dished, perforated and then bent and stretched into the desired shape is brought.

Das Verfahren nach der Erfindung wird im nachstehenden an Hand: des in der Zeichnung dargestellten Ausführungsbeispiels erläutert.The method according to the invention is described below with reference to: des Explained in the drawing illustrated embodiment.

Die Abh, i und 2 zeigen im Schnitt die Preßwerkzeuge mit dem Werkstück in zwei verschiedenen Stufen des Verfahrens.The Abh, i and 2 show in section the pressing tools with the workpiece in two different stages of the process.

Nach Abb. z wird das zwischen dem Gesenk 2 und dem Blechhalter 3 eingespannte Blech r durch. den Preßstempel 4 gekümpelt. Das Blech i wird dann mit einer Aussparung 5 versehen und alsdann., wie in Abb. q. dargestellt, durch den mit Ringen 6, 7 und 8 versehenen Stempel 9 in das Gesenk 2 gedrückt, wobei es durch Biegen und Strecken in die Form eines Vorschweißflansches gebracht wird.According to Fig. Z is clamped between the die 2 and the blank holder 3 Sheet r through. the ram 4 dumped. The sheet i is then provided with a recess 5 and then., As in Fig. Q. represented by the rings 6, 7 and 8 provided punch 9 pressed into the die 2, whereby it by bending and stretching is brought into the form of a welding neck flange.

Das Verfahren nach der Erfindung hat den Vorteil, daß es die Herstellung von Flanschen mit hohem Stutzen aus einem Stück ermöglicht.The method according to the invention has the advantage that it is manufacturing of flanges with high nozzles in one piece.
