Description
Der Erfindung liegt eine Strangpresse zugrunde, auf der mit Hilfe
eines am Preßstempel angeordneten oder eines durch diesen hindurchgeführten Dornes
Hohlprofile gepreßt werden. Vor Beginn der Pressung wird der Dorn in die Matrize
eingeführt, er bildet so den formenden Durchflußquerschnitt. Neben der Herstellung
von zylindrischen Hohlkörpern, Rohren werden auf ein und derselben Presse Hohlkörper
hergestellt, deren Querschnittsformen (Profile) je nach Anforderung wechseln. Die
Werkzeuge, Dorn und Matrize, müssen jeweils ausgewechselt und genau zueinander einzentriert
werden. Diese Einzentrierung bietet beim Pressen von Rohren keine besonderen Schwierigkeiten,
weil es hier lediglich darauf ankommt, Dorn und Matrize in achsgleiche Anordnung
zueinander zu bringen. Bei Profilpressungen müssen Matrize und Preßstempel außer
in die achsgleiche Lage auch in die gleiche Winkelstellung hinsichtlich des Profils
gebracht werden. Diese betriebstechnische Notwendigkeit erschwerte die Einzentrierung
der Werkzeuge bisher sehr. Die Genaueinstellung derselben wird auf Grund des Ausfalls
der Erstpressungen vorgenommen. Das machte bisher die Freilegung der Matrize erforderlich,
um ihre Nacheinstellung durchführen ztt können.
