Abstract

Bei einem Verfahren zum Strangpressen eines Hohlprofils (12) od.dgl. Körpers aus einem Barren, der in einer Rezipientenbohrung eines Aufnehmers (18) geführt und mittels eines Pressstempels (16) in Pressrichtung einem Formgebungsquerschnitt eines Formwerkzeuges (32) zugebracht wird, soll der Barrenwerkstoff unter Pressdruck in einen zentralen Einlauf (64) des Formwerkzeuges (32) eingebracht und die dabei entstehende duktile Masse in einem Winkel zur Pressrichtung nach außen durch mehrere Kanäle (66) zum Formgebungsquerschnitt geführt werden. Die Hauptbelastung wird durch den Pressdruck außerhalb des zentralen Einlaufes (64) und des formgebenden Bereiches zugeführt und bevorzugt durch die Presskraft außerhalb des formgebenden Bereiches in Stützwerkzeuge abgeleitet.

Figure 00000001
In a method for extruding a hollow profile (12) or the like. Body from a billet, which is guided in a recipient bore of a transducer (18) and brought to a shaping cross section of a molding tool (32) in the pressing direction by means of a press ram (16), the billet material is to be pressed into a central inlet (64) of the molding tool (32 ) and the resulting ductile mass is led outwards at an angle to the pressing direction through several channels (66) to the shaping cross section. The main load is supplied by the pressing pressure outside the central inlet (64) and the shaping area and is preferably diverted into supporting tools by the pressing force outside the shaping area.
