Abstract

Die Erfindung betrifft ein Verfahren und eine Vorrichtung zur Herstellung von zwei- oder mehrlagigen Verbundstäben aus zylindrischen, zentrisch zueinander angeordneten La­ gen unterschiedlicher Werkstoffe aufweisenden Werkstücken bzw. Vormaterialkörpern unter Einsatz von in einer zur Stabachse senkrechten Ebene gleichzeitig auf das Werk­ stück einwirkenden, insbesondere schlagenden oder drückenden und dieses verformenden Werkzeugen. Erfin­ dungsgemäß ist vorgesehen, daß das Werkstück fortschrei­ tend über seine Länge im Verformungsbereich der zumindest einen Abschnitt mit einer kegeligen Arbeitsfläche be­ sitzenden Werkzeuge einer Verformung zu zumindest einem (Kreis)Kegelstumpf unterworfen wird. The invention relates to a method and a device for the production of two or multi-layer composite rods from cylindrical, centrally arranged La against different workpieces or pre-material bodies using in a for Plane axis vertical plane simultaneously on the work piece acting, in particular beating or pressing and deforming tools. Erfin In accordance with the invention it is provided that the workpiece screams tend over its length in the deformation range of at least a section with a conical work surface seated tools of deformation to at least one (Circle) truncated cone is subjected.
