Hierzu ist zwischen dem Bauteil (1, 2) und der Matrize ein Schmiermittel vorgesehen.The invention relates to a production process for extruded or continuously cast components (1, 2). The components (1, 2) are calibrated for the purpose of Maßgebung in a forming process to the required tolerance by means of a die. For this purpose, a lubricant is provided between the component (1, 2) and the die.
Description
Die Erfindung bezieht sich auf ein Verfahren zur Herstellung eines Bauteils für Kraftfahrzeuge aus einem Stranggussteil oder Strangpressteil einer Metalllegierung.The The invention relates to a method for producing a component for motor vehicles from a continuous casting or extrusion of a metal alloy.
Aus der JP 2002-180809 ist ein Ventilantrieb eines Kraftfahrzeuges bekannt, dessen Rotor und Gehäuse aus einer stranggepressten Aluminiumlegierung gefertigt ist. Der Pressling wird dabei in der gewünschten Länge abgeschnitten und anschließend in einem Schneid- und Polierprozess bearbeitet.Out JP 2002-180809 discloses a valve drive of a motor vehicle, its rotor and housing is made of an extruded aluminum alloy. Of the Pressling will be in the desired Length cut off and subsequently processed in a cutting and polishing process.
Der Erfindung liegt die Aufgabe zugrunde, ein Herstellungsverfahren derart auszubilden und anzuordnen, dass eine schnelle und kostengünstige Herstellung gewährleistet ist.Of the Invention is based on the object, a production process such form and arrange that a fast and inexpensive production guaranteed is.
Gelöst wird die Aufgabe erfindungsgemäß dadurch, dass durch Teilen des Stranggussteils bzw. -profils oder des Strangpressteils bzw. -profils ein Bauteil-Rohling hergestellt wird und der Bauteil-Rohling in einem Umformprozess vor oder nach dem Teilen mittels einer Matrize auf das erforderliche Maß des Bauteils kalibriert wird.Is solved the task according to the invention by by dividing the continuous casting part or profile or the extruded part or -profils a component blank is produced and the component blank in a forming process before or after dividing by means of a die to the required degree of Component is calibrated.
Hierdurch wird erreicht, dass der erstellte Bauteil-Rohling nicht durch einen aufwändigen Zerspan- bzw. Schleifprozess bearbeitet werden muss. Der Umformprozess ist deutlich schneller und einfacher zu bewerkstelligen, da der Bauteil- Rohling lediglich durch einen Pressvorgang innerhalb der Matrize bzw. durch die Matrize erfolgt.hereby is achieved that the created component blank not by a complex Machining or grinding process must be edited. The forming process is much faster and easier to do, because of the Component blank only by a pressing process within the die or through the matrix is done.
Hierzu ist es vorteilhaft, dass die Umformung des Bauteil-Rohlings auf das Fertigmaß des Bauteils durch einen Kaltpress- oder Kaltformprozess, einen Halbwarmpress- oder Halbwarmformprozess oder einen Warmpress- oder Warmformprozess erreicht wird.For this it is advantageous that the deformation of the component blank on the Finished measure of Component through a cold-press or cold-forming process, a semi-hot or semi-hot forming process or a hot pressing or thermoforming process is reached.
Der Umformprozess kann dabei im kalten Zustand des Bauteil-Rohlings erfolgen. Es ist auch vorgesehen, den Bauteil-Rohling unter Berücksichtigung der Wärmeausdehnung in einem erwärmten Zustand innerhalb der Matrize umzuformen.Of the Forming process can be done in the cold state of the component blank. It is also envisaged, the component blank, taking into account the thermal expansion in a heated state to transform within the matrix.
Eine zusätzliche Möglichkeit ist gemäß einer Weiterbildung, dass der Bauteil-Rohling und/oder die Matrize zumindest in Teilbereichen der miteinander in Berührung stehenden Oberflächen vor dem Kalibrieren mit Schmiermittel benetzt werden.A additional possibility is according to a further development, that the component blank and / or the die at least in some areas the one in touch standing surfaces Wipe with lubricant before calibrating.
Die Verwendung von Schmiermitteln gewährleistet einen verschleißfreien Umformvorgang, so dass Kaltschweißvorgänge zwischen dem Bauteil und der Matrize verhindert werden. Das Bauteil bzw. die Matrize sind dabei zumindest in dem kritischen, einen Kaltschweißvorgang unterstützenden Bereich der korrespondierenden Oberflächen, mit Schmiermitteln benetzt bzw. belegt.The Use of lubricants ensures a wear-free Forming process, allowing cold welding between the component and the template can be prevented. The component or the die are at least in the critical, a cold welding process supportive Area of corresponding surfaces, wetted with lubricants or occupied.
Ferner ist es vorteilhaft, dass als Schmiermittel Öl, Festschmiermittel und/oder Kunststoff verwendet wird.Further It is advantageous that as a lubricant oil, solid lubricant and / or Plastic is used.
Die Verwendung von Festschmiermitteln wie Fett oder spritzbare Kunststoffschmiermittel gewährleisten den Umformprozess ohne Kaltschweißvorgänge.The Use of solid lubricants such as grease or sprayable plastic lubricants guarantee the forming process without cold welding.
Vorteilhaft ist es hierzu auch, dass die Größe des Bauteils zumindest teilweise durch einen nach dem Herstellungsprozess des Bauteil-Rohlings stattfindenden Umformprozess gebildet ist.Advantageous It is also this that the size of the component at least partially by an after-manufacturing process of the Part forming blank forming process is formed.
Der Umformprozess ist dabei wesentlich einfacher und schneller zu gestalten als ein Zerspan- oder Schleifprozess. Das so gebildete Bauteil weist die erforderlichen Toleranzmaße auf.Of the Forming process is much easier and faster as a cutting or grinding process. The thus formed component has the required tolerance dimensions on.
Gemäß einer bevorzugten Ausführungsform der erfindungsgemäßen Lösung ist schließlich vorgesehen, dass das Bauteil als Rotor oder als Rotorgehäuse für einen Nockenwellenversteller ausgebildet ist.According to one preferred embodiment of inventive solution in the end provided that the component as a rotor or as a rotor housing for a Camshaft adjuster is formed.
Von besonderer Bedeutung ist für die vorliegende Erfindung, dass der Rotor vorzugsweise vier, mit Bezug zu einer Mittelachse gleichmäßig über den Umfang verteilt angeordnete Flügel aufweist.From special meaning is for the present invention that the rotor is preferably four, with Reference to a central axis evenly distributed over the circumference wing having.
Im Zusammenhang mit der erfindungsgemäßen Ausbildung und Anordnung ist es von Vorteil, dass das Gehäuse vorzugsweise vier, mit Bezug zu einer Mittelachse gleichmäßig über den Umfang verteilt angeordnete Ausnehmungen für die Flügel aufweist. Beim Betrieb wird die Winkellage des jeweiligen Flügels innerhalb der Ausnehmung mit Bezug zur Mittelachse verändert.in the Connection with the construction and arrangement according to the invention it is beneficial that the housing preferably four, with respect to a central axis uniformly over the Circumference distributed arranged recesses for the wings. During operation the angular position of the respective wing within the recess changed with respect to the central axis.
Weitere Vorteile und Einzelheiten der Erfindung sind in den Patentansprüchen und in der Beschreibung erläutert und in der Figur dargestellt.Further Advantages and details of the invention are in the claims and explained in the description and shown in the figure.
