Abstract
Description
Die Erfindung betrifft eine Vorrichtung zum Gießen eines Zylinderkurbelgehäuses für eine Brennkraftmaschine aus einer Leichtmetalllegierung, wobei die Leichtmetalliegierung Ober einen Anschnitt in einem Bereich des Lagerstuhls unterhalb eines Zylinderrohres des Zylinderkurbelgehäuses eingegossen wird. Darüber hinaus betrifft die Erfindung ein nach diesem Verfahren hergestelltes Zylinderkurbelgehäuse.The invention relates to a device for casting a cylinder crankcase for an internal combustion engine made of a light metal alloy, wherein the light metal alloy is poured over a gate in a region of the bearing block below a cylinder tube of the cylinder crankcase. Moreover, the invention relates to a cylinder crankcase produced by this method.
Motorblöcke, die auch Zylinderkurbelgehäuse genannt werden, werden heute zu einem großen Teil aus Leichtmetallen gefertigt. Bevorzugte Werkstoffe sind hierbei Aluminium- und/oder Magnesiumlegierungen. Ein entscheidender Vorteil dieser Legierungen ist ihr geringes Gewicht, wodurch die Kraftfahrzeuge in denen sie eingesetzt werden ein geringes Gesamtgewicht aufweisen. Um den Anforderungen an die immer weiter steigenden Leistungen in den Motoren gerecht zu werden, ist es hierbei notwendig, dass ein homogenes Werkstoffgefüge im gesamten Zylinderkurbelgehäuse vorliegt. Das Werkstoffgefüge wird hierbei auch durch die Lage des Anschnitts in der Gießmaschine zum herzustellenden Kurbelgehäuse beeinflusst.Engine blocks, which are also called cylinder crankcases, are today largely made of light metals. Preferred materials here are aluminum and / or magnesium alloys. A key advantage of these alloys is their low weight, whereby the motor vehicles in which they are used have a low total weight. In order to meet the requirements for the ever increasing power in the engines, it is necessary here that a homogenous material structure is present in the entire cylinder crankcase. The material structure is also influenced by the position of the gate in the casting machine to be produced crankcase.

Durch die Verlegung der Angüsse in den Bereich der Seitenwände gelingt es, die Lagerstühle schneller erstarren zu lassen, wodurch bessere Gefügeeigenschaften in diesem Bereich eingestellt werden können. Nachteilig wirkt sich hierbei der Abstand der Angußleiste zum Lagerstuhlbereich aus, da im Bereich des Lagerstuhls die höchste Volumenkonzentration vorliegt und es in diesem Bereich zu unterschiedlichen Abkühlgeschwindigkeiten und somit auch zu inhomogenen Gefügeausbildungen kommen kann.By laying the sprues in the area of the side walls, it is possible to solidify the storage chairs faster, whereby better structural properties can be set in this area. The disadvantage here is the distance of the runner to the bearing block area, since there is the highest volume concentration in the area of the bearing block and it can come in this area to different cooling rates and thus also inhomogeneous microstructures.
Die Erfindung stellt sich die Aufgabe, eine Vorrichtung bereit zu stellen, mit der einerseits hohe Lagerstuhlfestigkeiten erreicht werden und mit der mit reduzierten Taktzeiten gefertigt werden kann. Darüber hinaus ist es Aufgabe der Erfindung ein nach diesem Verfahren gefertigtes Zylinderkurbelgehäuse bereit zu stellen.The object of the invention is to provide a device with which, on the one hand, high bearing stability can be achieved and with which reduced cycle times can be produced. In addition, it is an object of the invention to provide a manufactured according to this method cylinder crankcase.
Die erfindungsgemäße Aufgabe wird dadurch gelöst, dass die Vorrichtung im Bereich eines einen Lagerstuhl bildenden Seitenschiebers kühlbar ist, so dass eine feine Gefügeausbildung im Lagerstuhl erzielbar ist. Durch die erfindungsgemäße Vorrichtung ist nun die Möglichkeit geschaffen, das Zylinderkurbelgehäuse beziehungsweise die Form zur Herstellung des Zylinderkurbelgehäuses derart zu füllen, das der Bereich der höchsten Volumenkonzentration unmittelbar gefüllt wird, wobei sich aus der Lage zum Anschnitt ein optimiertes Temperaturgefälle ergibt, so dass sich ein homogenes WerKstoffgefüge im Zylinderkurbelgehäuse ausbildet. Durch die Lage des Anschnittes an der äußeren Oberfläche des Zylinderkurbelgehäuses unterhalb der Zylinderrohre ist die speisungstechnische Versorgung des Lagerstuhls, der den Bereich der höchsten Volumenkonzentration bildet, wie auch der Schraubenpfeifen gewährleistet. Darüber hinaus ist ein Vorgießen der Zugankerbohrungen des Lagerstuhls möglich und durch sequenzielle Kühlungen des den Lagerstuhl bildenden Seitenschiebers ist eine sehr feine Gefügeausbildung erzielbar. Eine derartige feine und homogene Gefügeausbildung bewirkt eine hohe statische und dynamische Festigkeit des Bauteils.The object according to the invention is achieved in that the device can be cooled in the area of a side slide forming a bearing block, so that a fine structural formation in the bearing block can be achieved. By means of the device according to the invention, it is now possible to fill the cylinder crankcase or the mold for the production of the cylinder crankcase in such a way that the area of the highest volume concentration is directly filled, whereby an optimized temperature gradient results from the position to the gate, so that a homogenous Who forms material structure in the cylinder crankcase. Due to the location of the gate on the outer surface of the cylinder crankcase below the cylinder tubes is the power supply of the bearing block, which forms the region of highest volume concentration, as well as the screw pipes ensured. In addition, a Vorgießen the Zugankerbohrungen the bearing block is possible and by Sequential cooling of the bearing block forming side shifter is a very fine structure formation achievable. Such a fine and homogeneous microstructure results in a high static and dynamic strength of the component.
Nachfolgend wird die Erfindung anhand eines Ausführungsbeispiels näher erläutert. Es zeigt:
- Figur 1
- den Schnitt durch ein erfindungsgemäß ausgebildetes Gießwerkzeug mit einem gefertigten Zylinderkurbelgehäuse.
- FIG. 1
- the section through an inventively designed casting tool with a manufactured cylinder crankcase.
In der Figur 1 ist das Zylinderkurbelgehäuse 1 in einer seiner möglichen Gießlagen im Querschnitt dargestellt. Begrenzt wird das Zylinderkurbelgehäuse 1 von einer beweglichen Formhälfte 2 und einer festen Formhälfte 3 sowie den seitlichen Schiebern 4 und 5. Bei dem dargestellten Zylinderkurbelgehäuse 1 handelt es sich um einen Motor mit Schürze 6, der auch als Schürzenmotor bezeichnet wird. Die Zylinder 7 sind von Öffnungen 8 umgeben, die den Kühlwassermantel 8 bilden. Oberhalb des oberen und unterhalb des unteren Kührwassermantels 8 sind Versteifungsrippen 9 dargestellt. Der Anschnitt 10 liegt unterhalb der Zylinderrohre 7 des Zylinderkurbelgehäuses 1. Hierbei befindet sich die Anschnittleiste 11 unmittelbar am Kurbelraum des Zylinderkurbelgehäuses 1, wodurch das mittels dieses Verfahrens hergestellte Zylinderkurbelgehäuse 1 eindeutig identifizierbar ist.In the figure 1, the cylinder crankcase 1 is shown in one of its possible casting layers in cross section. The cylinder crankcase 1 is limited by a
Anzumerken bleibt hier, dass sich die erfindungsgemäß einzusetzende Anschnittzone Z, je nach Ausführungsform, in einem Bereich der Schürze 6 befinden kann. So ist es beispielsweise vorstellbar, den Anschnitt 11 in den Bereich der Versteifungsrippen 16 zu legen. Als Gießverfahren stehen hierbei Niederdruck-, Druckguß- und das Squeeze-Casting-Verfahren zur Verfügung. Als Variante kann die Füllung auch mittels geeignetem Anschnittsystem durch Schwerkraft erfolgen.It should be noted here that the gate zone Z to be used according to the invention, depending on the embodiment, can be located in an area of the
Zur Vermeidung waagrechter Fließwege ist auch eine Neigung des Gießwerkzeugs von 1° - 25° möglich. Unterhalb des Anschnitts 11 befindet sich der Verteiler 12, der mit dem Steigrohr 13 verbunden ist. Durch definierte Druckbeaufschlagung P des Gießofens 14 wird das Gießwerkzeug 2, 3, 4, 5 turbulenzarm steigend mit einer Leichtmetalliegierung, aus Aluminium- und/oder Magnesium-Basis, gefüllt.To avoid horizontal flow paths and a tilt of the casting tool of 1 ° - 25 ° is possible. Below the
Im Gegensatz zum Anschnitt 11 im Bereich des Lagerstuhls 15 bietet das erfindungsgemäße Verfahren den Vorteil, dass der Lagerstuhl 15 kühlbar ist, wodurch ein definiertes Abkühlen und somit ein homogenes Werkstoffgefüge einstellbar wird. Im Bereich des Anschnitts 11 liegen verfahrensbedingt die längsten Abkühlzeiten, da hier ebenfalls hohe Volumenkonzentrationen vorliegen und die flüssige Legierung von hier aus in sämtliche Bereiche der Gießform 2, 3, 4, 5 eingegossen wird, sowie das Nachverdichten erfolgt. Somit ergeben sich im Bereich des Anschnitts sehr lange Erstarrungszeiten, was zu einer grobkörnigen Struktur des Gefüges führt, was sich wiederum nachteilig auf die Festigkeit auswirkt. Durch die Verlegung des Anschnitts 11 in den sehr viel geringer beanspruchten Bereich des Zylindermantels am unteren Ende der Zylinderrohre 7 und im Bereich der äußeren Oberfläche, wirken sich die Inhomogenitäten im Anschnitt vorteilhafter Weise nicht auf die Festigkeit in den hoch beanspruchten Bereichen wie Lagerstuhl 15 und Zylinderlauffläche aus.In contrast to the
Mit dem erfindungsgemäßen Verfahren sind auch übereutektische Aluminium-Silizium-Legierungen gießbar. Die Anschnittslage gewährleistet hierbei eine gleichmäßige Verteilung des Primär-Siliziums was sich wiederum positiv auf die Festigkeit des Zylinderkurbelgehäuses 1 auswirkt. Senkrecht zu den Siebkammern in den Gießkammem 12 sind ein oder zweiteilige Squeeze-Cast-Stempel 17 angeordnet, durch die ein Nachpressen oder Speisen des Metalls möglich ist und durch die ein definiertes Erstarren oder Abfrieren des Angußbereiches erzielt wird. Der Squeeze-Cast-Stempel 17 ist dabei in Richtung des Pfeils F bewegbar. An den Siebflanken können bornitrit- oder grafithaltige keramische Faserplatten appliziert werden, die die oder den Squezze-Cast-Stempel 17 vor der direkten Einwirkung der Leichtmetalllegierung schützen. Bei sehr niedrigen Wandstärken ist der Einsatz einer höhenreduzierten Zylinderpinole 7 zur Speisungsversorgung der Anschnitt abgewandten Schraubenpfeifen erforderlich.Hypereutectic aluminum-silicon alloys can also be cast by the method according to the invention. The gate position ensures a uniform distribution of the primary silicon, which in turn has a positive effect on the strength of the cylinder crankcase 1. Perpendicular to the sieve chambers in the Gießkammem 12 one or two-piece squeeze-cast-
Das in der Figur 1 dargestellte Gießverfahren zeigt ein Gießen mit Niederdruck, wobei die Gießform 2, 3, 4, 5 mit cirka 0,4 bar gefüllt wird. Um den Schwund der Leichtmetalllegierung während der Erstarrung zu kompensieren, wird im Bereich 18 des Angusses 10 eine nicht dargestellte Abriegeleinheit vorgesehen. Die Abriegeleinheit ist beispielsweise ein Schieber, der den Anguss 10 vom Verteiler 12 trennt, so dass die noch flüssige Leichtmetalllegierung nach dem Schließen des Schiebers und der Wegnahme des Drucks P durch das Steigrohr 13 in den Gießofen 14 zurückfließen kann. Ist die Abriegeleinheit geschlossen, so kann mittels des Stempels 17 ein Nachdruck auf die Gießform 2, 3, 4, 5 ausgeübt und somit einem Schwund der Leichtmetalllegierung entgegengewirkt werden.The casting process shown in Figure 1 shows a casting with low pressure, wherein the
Das erfindungsgemäße Verfahren eignet sich für den Niederdruck, Druckguß und das Squeeze-Casting, die allgemeine Verfahren zum Herstellen von Zylinderkurbelgehäusen darstellen. Darüber hinaus ist es erfindungsgemäß vorstellbar infiltrierbare Preformen in die mittels Verfahrens hergestellten Zylinderkurbeigehäuse 1 zum Beispiel im Bereich der Zylinder 7 einzugießen und/oder ein aus einem Stahlwerkstoff hergestelltes Eingußteil, zum Beispiel im Lagerstuhlbereich 15, zu vergießen.The inventive method is suitable for low pressure, die casting and squeeze casting, which represent general methods for producing cylinder crankcases. In addition, according to the invention, it is conceivable to infiltrate infiltratable preforms into the cylindrical cogging housing 1 produced by means of a method, for example in the area of the
