Description

Die Erfindung betrifft ein Verfahren zur endkonturnahen Fertigung von Bauteilen bzw. Halbzeugen aus schwer zerspanbaren Leichtmetalllegierungen und ein durch das Verfahren hergestelltes Bauteil bzw. Halbzeug. The invention relates to a method for the near-net-shape production of components or Semi-finished products made of hard-to-cut light metal alloys and one through the process manufactured component or semi-finished product.

Herkömmlicherweise wird bei der pulvermetallurgischen Herstellung von hochverschleißfesten Bauteilen der Werkstoff als Pulver angeliefert, im klassischen Pulverpressverfahren verarbeitet, gesintert, wärmebehandelt und kalibriert. Die Eigenart eines solchen hochverschleißfesten Werkstoffes ist jedoch ein starker Verzug beim Sintern, der durch die notwendige Flüssigphasensinterung hervorgerufen wird. Die geforderte Form- und Maßgenauigkeit beim anschließenden Kalibrieren ist hier eingeschränkt. Conventionally, in the powder metallurgical production of highly wear-resistant components of the material delivered as powder, in the classic powder press process processed, sintered, heat treated and calibrated. The peculiarity of such highly wear-resistant material is, however, a strong delay in sintering due to the necessary Liquid phase sintering is caused. The required form and dimensional accuracy when subsequent calibration is restricted here.

Um diesen Nachteil der oben genannten Werkstoffe im Punkt Genauigkeit zu beheben, wird erfindungsgemäß ein Verfahren gemäß dem Anspruch 1 und ein Bauteil bzw. Halbzeug gemäß dem Anspruch 11 zur Verfügung gestellt. Die Unteransprüche richten sich auf bevorzugte Ausführungsformen der Erfindung. To eliminate this disadvantage of the above materials in terms of accuracy, according to the invention a method according to claim 1 and a component or semi-finished product provided according to claim 11. The subclaims are raised preferred embodiments of the invention.

Mit anderen Worten und in einer Ausführungsvariante kann die Erfindung auch bezeichnet werden als Verfahren zur Herstellung eines Sinterteiles aus Sinterleichtmetall mit veränderlichen Anteilen an Verschleißschutzpartikeln als Legierungsanteil. In other words and in an embodiment variant, the invention can also be referred to are used as a method for producing a sintered part from sintered light metal variable proportions of wear protection particles as alloy components.

Gemäß einer Ausführungsform der Erfindung ist diese ein Verfahren zur Herstellung von Sinterformteilen aus Leichtmetallen, vorzugsweise Aluminium mit 10-30% Siliziumanteilen, Mg 0-3%, Cu 0-5%, Zn und Fe 0-7%. Auch andere Leichtmetalle mit veränderten Si-Anteilen sind so herstellbar. Alternativ zu Si als Verschleißträger können auch Hartstoffpartikelzusätze wie Oxide, Carbide und Silikate mit Anteilen von 0-30% eingesetzt werden. According to one embodiment of the invention, this is a method for producing Sintered molded parts made of light metals, preferably aluminum with 10-30% Silicon shares, Mg 0-3%, Cu 0-5%, Zn and Fe 0-7%. Other light metals with changed Si components can be produced in this way. As an alternative to Si as a wear carrier, too Hard particle additives such as oxides, carbides and silicates with proportions of 0-30% are used.

Das Verfahren vereinigt vorteilhafterweise die Verfahren Kalt- oder Heißisostatpressen, Strangpressen, Sägen und Kalibrieren mit vorzugsweise integriertem Facettieren, gegebenenfalls Warmbehandeln und Schmieden zu einer neuartigen Gesamtheit. The process advantageously combines the processes of cold or hot isostatic presses, Extrusion, sawing and calibration with preferably integrated faceting, if necessary, heat treatment and forging to a new type.

Ausgangspunkt der Erfindung ist bei einer Ausführungsform der pulvermetallurgische Werkstoff Aluminium mit Si-Anteilen von ca. 14% der unter anderem in einer Anwendung als Kettenrad gegen eine Stahlkette, als Rotor und Stator in einem Nockenwellenverstellersystem oder einer Ölpumpe hervorragende, bisher nicht gekannte, gute Verschleißeigenschaften besitzt. In one embodiment, the starting point of the invention is powder metallurgy Material aluminum with Si components of approx. 14% which is used in an application as Sprocket against a steel chain, as a rotor and stator in a camshaft phasing system or an oil pump with excellent, previously unknown, good wear properties has.

In bevorzugter Ausführung wird die Erfindung mit folgenden Verfahrensschritten umgesetzt:

  • - Verpressen des Rohpulvers in einer Kalt- oder Heißisostatpresse zu einem Bolzen oder einer Form, die zum späteren Strangpressen geeignet ist. Vorteilhaft ist hier der Einsatz eines gepressten Bolzens aus Leichtmetallpulver, um im Gegensatz zu schmelzmetallurgisch hergestellten Bolzen ein gleichmäßigeres Gefüge ohne Lunker und Seigerungen etc. (mit gleichmäßig guter Si-Verteilung und damit guten Verschleißeigenschaften) zu erhalten;
  • - Strangpressen des Bolzens nahe der Sintertemperatur des Leichtmetalls. Dabei Rekristallisation des Gefüges und Temperaturerhöhung bis zur optimalen Temperatur. Der Strangpressbolzen hat nun schon eine sehr gute Maßtoleranz, die für manche Bauteile schon genügen kann;
  • - wenn die Maßtoleranz noch nicht ausreichend ist, um hochpräzise, einbaufertige Konturen zu erhalten, wird der stranggepresste Bolzen noch weiter nachkalibriert;
  • - der Strangpressbolzen wird in das für das Bauteil später notwendige Maß in geeigneter Weise getrennt. Gegebenenfalls wird er dann noch warmbehandelt, einem Nachkalibrierarbeitsgang unterzogen und an definierten Kanten facettiert. Denkbar ist auch, den Strang als Ganzes in einer Art Ziehprozess auf genaue Maße zu bringen und danach zu trennen.
In a preferred embodiment, the invention is implemented with the following process steps:
  • - Pressing the raw powder in a cold or hot isostatic press into a bolt or a mold that is suitable for later extrusion. It is advantageous to use a pressed bolt made of light metal powder in order to obtain a more uniform structure without blowholes and segregations etc. (with uniformly good Si distribution and thus good wear properties), in contrast to bolts produced using melt metallurgy;
  • - extrusion of the bolt near the sintering temperature of the light metal. Thereby recrystallization of the structure and temperature increase up to the optimal temperature. The extrusion bolt now has a very good dimensional tolerance, which may be sufficient for some components;
  • - If the dimensional tolerance is not yet sufficient to obtain high-precision, ready-to-install contours, the extruded bolt is recalibrated;
  • - The extrusion pin is separated into the dimension required for the component later in a suitable manner. If necessary, it is then heat treated, subjected to a recalibration process and faceted on defined edges. It is also conceivable to bring the strand as a whole to exact dimensions in a kind of drawing process and then to separate it.

Erfindungsgemäß wird die bei Sinterteilen übliche Präzision erzeugt. Die großen Verzüge wie im oben beschriebenen klassischen Sinterverfahren treten hier nicht mehr auf. Der hochverschleißfeste Werkstoff ist in engen Maßtoleranzen herstellbar. According to the invention, the precision that is customary in sintered parts is generated. The big delays like in the classic sintering process described above no longer occur here. The highly wear-resistant material can be manufactured within narrow dimensional tolerances.
