摘要： Die Erfindung bezieht sich auf eine Matrize zum Strangpressen von metallischen Werkstoffen mit einer konkav-konisch ausgebildeten Einlauffläche, bestehend aus einem formgebenden Matrizenteil aus hochverschleißfestem Werkstoff und einem Stützteil aus zähfestem Werkstoff. Zur Vermeidung von Rißbildungen und Brüchen und zur Verstärkung der Verbindung der Teile wird vorgeschlagen, daß die Metallverbundfläche (3) zwischen formgebendem Matrizenteil (1) und Stützteil (2) räumlich gekrümmt ausgebildet ist.Die Herstellung des Matrizenrohkörpers erfolgt durch Warmschmieden von einem aus mindestens zwei Werkstoffen bestehenden Vormaterial, vorzugsweise durch Gesenkschmieden.

摘要： In a method of forming an extrusion die by forming an extrusion aperture 11 in a die piece 10, forcing a flowable material 14 at least partly through the extrusion aperture so that the leading surface 16 of the material becomes deformed in the extrusion direction, and then reshaping the die piece in such a manner that the axial bearing depth of the extrusion aperture at any location around its periphery corresponds to the deformation of the leading surface of the flowable material at that location, as an additional step, before or after the reshaping, the axial bearing depth of the aperture 11, at locations around its periphery, is adjusted for example by machining one surface of the die piece, by amounts dependent on the distance of said locations from the centre of the die piece.

摘要： The subject invention relates to a new method for manufacturing extrusion die tools that eliminates the step of hardening the steel after cutting the steel to form the desired extrusion die tool design. The new method involves the steps of cutting and finishing steel to form the desired extrusion die tool design, coating the die tool, or parts thereof, and hardening the coated die tool. The new method for manufacturing extrusion die tools reduces the time and the cost involved in their manufacture.

摘要： An extrusion die comprises a die body defining a die cavity (18). The cavity (18) is shaped such that the die body includes a male portion (24) and a female portion (26). A leading edge (18a) of a part of one side of the die cavity (18) is out of alignment with a leading edge (18a) of an opposing part of the die cavity (18), at rest, such that, in use, when deflection of parts of the die occurs, the leading edges (18a) substantially align.
