摘要： In order to provide a drawing method for shaping workpieces of metallic materials, the workpiece (3) being drawn through a die aperture (2) narrowing in the drawing direction (4), and thereby reduced in cross section and increased in length, by way of forming under combined tensile and compressive conditions, where high levels of shaping can be achieved in each operation and, if need be, particularly preferred mechanical properties of the workpiece can be produced during the drawing process, it is proposed that the workpiece (3) and/or the drawing die (1) is/are moved during the drawing process in an oscillating manner about an axis (5) running transversely in relation to the drawing direction (4).

摘要： The present invention relates to a drawing die (1) for drawing iron and steel rods having a comparatively large diameter, which comprises a framework body (2), defining a throughgoing opening, housing an upper inlet element (5) and a drawing core (20), which are axially aligned. The main feature of the invention is that the die (1) further comprises a lower outlet element (30), which can be removably coupled to the framework body (2) and axially engaged with the drawing core (20).

摘要： Im Rahmen eines Umformverfahrens zum Erzeugen einer Schrägverzahnung eines zylindrischen Werkstücks durch Fließpressen wird einer axialen Umformbewegung eines Umformwerkzeugs (3) und eines Werkstückrohlings (4) eine in einer Umfangsrichtung (7) des Umformwerkzeugs (3) und des Werkstückrohlings (4) ausgeführte Relativbewegung des Umformwerkzeugs (3) und des Werkstückrohlings (4) überlagert. Aufgrund einer aus der gegenseitigen Überlagerung der axialen Umformbewegung und der Umformbewegung in Umfangsrichtung resultierenden Umform-Relativbewegung des Umformwerkzeugs (3) und des Werkstückrohlings (4) wird an dem Werkstückrohling (4) die Schrägverzahnung des Werkstücks erzeugt, indem das Umformwerkzeug (3) bei der resultierenden Umform-Relativbewegung mit einer formgebenden Schrägverzahnung (16) in den Werkstückrohling (4) eingreift.
Eine Umformmaschine (1) ist zur Durchführung des vorgenannten Verfahrens ausgebildet.-
