Abstract
Description
Die Erfindung bezieht sich auf ein spanlos formgebendes Werkzeugteil, insbesondere eine Patrize und/oder eine Matrize gemäß dem Oberbegriff des Anspruches 1.The The invention relates to a non-cutting shaping tool part, in particular a male mold and / or a die according to the preamble of Claim 1.
Aus
der
Aus der EP-PS 0 146 024 ist ein Verfahren zum Verbinden eines aus einem nicht oxydischen Keramikmaterial, beispielsweise SiC, bestehenden Bauteiles mit einem aus einem metallischen Werkstoff, insbesondere Stahl, beispielsweise einem Crom-Molybdän-Srahl, bekannt, wobei angestrebt wird, das Keramikmaterial in einer solchen Weise dicht bzw. fest mit dem metallischen Werkstoff zu verbinden, dass unterschiedliche Wärmeausdehnungen des Keramikmaterials und des metallischen Werkstoffes weitgehendst ausgeglichen und eventuelle, aus unterschiedlichen Wärmeausdehnungen einerseits des metallischen Werkstoffes und andererseits des Keramikmaterials resultierende Spannungen auf einen minimalen Betrag reduziert werden, derart, dass das Entstehen von Bruchlinien im Keramikmaterial ausgeschlossen ist.Out EP-PS 0 146 024 is a method for connecting one of a non-oxidic ceramic material, for example SiC, existing components with one of a metallic material, in particular steel, for example, a crom-molybdenum beam, wherein is sought, the ceramic material in such a way dense or firmly connect with the metallic material that different Thermal expansions of the Ceramic material and the metallic material largely balanced and eventual, from different thermal expansions on the one hand the metallic material and on the other hand the ceramic material resulting Voltages are reduced to a minimum amount such that the emergence of fault lines in the ceramic material excluded is.
Der Erfindung liegt die Aufgabe zugrunde ein Werkzeugteil zur spanlos formgebenden Verformung von Werkstücken zu schaffen, welches sich bei geringem zusätzlichen Herstellungsaufwand durch eine Optimierung der Dauerstandsfestigkeit seiner formgebenden Oberfläche auszeichnet.Of the Invention is the object of a tool part for cutting to create shaping deformation of workpieces, which is with little additional Production costs by optimizing the creep rupture strength its shaping surface distinguished.
Diese Aufgabe wird erfindungsgemäß durch die im Anspruch 1 angegebenen Merkmale gelöst. Weitere, die Erfindung ausgestaltende vorteilhafte oder zweckmäßige Maßnahmen sind in den Unteransprüchen angegeben.These The object is achieved by the achieved in claim 1 features. Further, the invention ausgestaltende advantageous or expedient measures are given in the dependent claims.
Einer der wesentlichsten Vorteile des erfindungsgemäßen Aufbaues eines Werkzeugteiles besteht zunächst darin, dass seine formgebende äußere Oberfläche mit einem geringstmöglichen Aufwand jedem jeweils zu bearbeitenden bzw. in eine bestimmte Form zu bringenden Ausgangsmaterial in der Weise angepasst werden kann, dass eine von den spezifischen Eigenschaften des jeweils zu bearbeitenden Materials unabhängige hohe Dauerstandsfestigkeit des Werkzeugteiles gewährleistet werden kann. Insbesondere eröffnet der schichtweise Aufbau der formgebenden Oberfläche des Werkzeugteiles eine einfache Möglichkeit zur wenig aufwendigen Anpassung der formgebenden Oberflächenfestigkeit des Werkzeugteiles an unterschiedliche, aus den speziellen Anforderungen der zu bearbeitenden Material resultierende mechanische oder thermische Eigenschaften.one the most significant advantages of the construction of a tool part according to the invention exists first in that its shaping outer surface with a lowest possible Each effort to be processed or in a specific form can be adapted to be brought starting material in the manner that one of the specific characteristics of each to be worked on Material independent high creep resistance of the tool part can be ensured can. In particular, opened the layered structure of the shaping surface of the tool part a easy way for less complex adaptation of the shaping surface strength of the tool part to different, from the special requirements the material to be machined resulting mechanical or thermal Properties.
Darüber hinaus sollte ein in der erfindungsgemäßen Weise aufgebautes Werkzeug auch zur formgebenden Bearbeitung von nichtmetallischen Werkstoffen eingesetzt werden können, insbesondere auch dann, wenn die beabsichtigte formgebende Bearbeitung nur unter wärmeisolierten oder sogar wärmezuführungsabgängigen Bedingungen ausgeführt werden kann.Furthermore should be one in the manner according to the invention Built-tool also for the shaping processing of non-metallic materials can be used especially if the intended shaping process only under heat insulated or even heat delivery-off conditions accomplished can be.
Die Erfindung ist in der Zeichnung anhand eines Ausführungsbeispieles dargestellt und in der nachfolgenden Beschreibung erläutert.The The invention is illustrated in the drawing with reference to an embodiment and explained in the following description.
