Abstract

Die Erfindung betrifft ein Verfahren und eine Drückwalzmaschine zum Einbringen einer Sicke in ein zylindrisches, dünnwandiges Werkstück. Das Werkstück wird relativ zu mindestens einer Drückrolle in Rotation versetzt. Die Drückrolle ist mit einem Profil entsprechend der einzuformenden Sicke versehen. Die Drückrolle wird radial an das Werkstück zugestellt und dabei wird die Sicke eingeformt. Eine besonders genaue Ausformung der Sicke wird dadurch erzielt, dass gleichzeitig mit dem radialen Zustellen der Drückrolle und dem Einformen der Sicke das Werkstück mittels mindestens einem Druckstempel axial gestaucht wird.

Figure 00000001
The invention relates to a method and a pressure rolling machine for introducing a bead into a cylindrical, thin-walled workpiece. The workpiece is rotated relative to at least one spinning roller. The spinning roller is provided with a profile corresponding to the bead to be molded. The pressure roller is fed radially to the workpiece and the bead is formed in the process. A particularly precise shaping of the bead is achieved in that the workpiece is axially compressed by means of at least one pressure plunger at the same time as the spinning roller is fed radially and the bead is molded.
