Abstract

Es handelt sich um ein Umformwerkzeug mit einem Formraum (1) zum Herstellen von metallischen Werkstücken im Wege einer wirkmedienunterstützten Warmumformung. Das Werkzeugoberteil (2) weist zur Erzeugung einer Ausformung (8) an dem entstehenden rohrförmigen Werkstück (7) eine der Ausformung entsprechende Formausnehmung (9) mit einem in der Formausnehmung in Ausformrichtung geführten Gegenhalter (10) auf, der die Ausformgeschwindigkeit und Ausformtiefe der entstehenden Ausformung kontrolliert. Außerdem kann auf der dem Gegenhalter gegenüberliegenden Seite ein Schieber (12) vorgesehen sein, um den Werkstofffluss in Richtung der entstehenden Ausformung zu steuern.

Figure 00000001
It is a forming tool with a mold space (1) for the production of metallic workpieces by means of an active-media-assisted hot forming. To produce a formation (8) on the resulting tubular workpiece (7), the tool upper part (2) has a molding recess (9) corresponding to the molding with a counter-holder (10) guided in the molding recess in the molding direction, which produces the molding speed and molding depth of the resulting tool Formation controlled. In addition, a slide (12) may be provided on the opposite side of the counter-holder to control the flow of material in the direction of the resulting formation.
