Abstract

Ein Verfahren zur Herstellung eines Rohres mit partiell unterschiedlichen Wandstärken ist so ausgebildet, daß in ein Ausgangsrohr ein mit mindestens einer außenseitigen, beidseitig in axialer Richtung begrenzten Vertiefung (7) versehener Dorn (6) eingeschoben, anschließend ein Ziehring (8), dessen lichter Durchmesser kleiner ist als der Außendurchmesser des Ausgangsrohres, über das gegenüber dem Dorn (6) in Ziehrichtung gehaltene Rohr (2) gezogen wird, wobei ein Teil des Rohres (2) in die Vertiefung (7) gedrückt wird und danach der Dorn (6) unter radialem Herausdrücken der in der Vertiefung (7) einliegenden Rohrwandung aus dem Rohr (2) herausgezogen wird.

Figure 00000001
A method for producing a tube with partially different wall thicknesses is designed such that a mandrel (6) provided with at least one outer recess (7), which is delimited on both sides in the axial direction, is inserted into an outlet tube, followed by a drawing ring (8), the clear diameter of which is smaller than the outer diameter of the outlet pipe, over which pipe (2), which is held in the drawing direction relative to the mandrel (6), is pulled, part of the pipe (2) being pressed into the recess (7) and then the mandrel (6) underneath radial pushing out of the pipe wall lying in the recess (7) is pulled out of the pipe (2).
