Kolben für Brennkraftmaschinen und Verfahren
zu seiner HerstellungPistons for internal combustion engines and processes
for its manufacture
Die Erfindung betrifft einen Kolben aus einer Leichtmetallegierung für Brennkraftmaschinen sowie ein Verfahren zur Herstellung eines solchen Kolbens.The invention relates to a piston made of a light metal alloy for internal combustion engines and a method for producing such a piston.
Es ict bekannt, daß Kolben aus einer Leichtmetallegierung, wie
etwa aus einer Aluminiumlegierung, und insbesondere Kolben für
Dieselmotoren mit einer Brennkammer unter bestimmten Betriebsdrehzahlen an der Kolbenkrone aufreißen oder aufbrechen können.
Diesi-s Aufreißen tritt vor allem im Bereich um die Kante der
Brennkammer auf, und zwar besonders dann,, wenn die Brennkammer muldenartig bzw. einspringend ausgebildet ist.It is known that pistons made of a light metal alloy, such as an aluminum alloy, and in particular pistons for diesel engines with a combustion chamber, can tear or break open at the piston crown at certain operating speeds. Diesi-s tearing occurs mainly in the area around the edge of the
Combustion chamber on, especially if the combustion chamber is trough-like or re-entrant.
Es ist ebenfalls bekannt, daß dieses Aufreißen bzw. Aufbrechen dadurch vermieden werden kann, daß man eine eingegossene Ver-Stärkung
zur Anwendung bringt, die aus hochfesten Kupferlegierungen mit hoher thermischer Leitfähigkeit besteht, wie z.B.
aus Beryllium-Kupfer und Kupfer - Nickel - Silizium - Bronze,
wobei die bruchgefährdete Kante der Brennkammer maschinell in
dem aus der Kupferlegierung bestehenden Material ausgearbeitet wird.It is also known that this tearing or breaking can be avoided by using a cast-in reinforcement made of high-strength copper alloys with high thermal conductivity, such as
from beryllium copper and copper - nickel - silicon - bronze,
where the edge of the combustion chamber at risk of breakage is machined into
the material consisting of the copper alloy is worked out.
Da die Stärke der Aluminium! eg inning in der Kolbenkrone um don Bereich der Verstärkung aus der Kupferlegierung nicht geeignet ist, hohen Beanspruchungen standzuhalten, die aufgrund der Trägheitsbelastung dieser Verstärkung einwirken, ist es normalerweise erforderlich, die Verstärkung durch Beine zu verankern, die aus rostfreiem Stahl oder aus einer Kupferlegierung bestehen und in die kühleren Teile des Kolbens ragen.Because the strength of aluminum! eg inning in the piston crown to don The area of reinforcement from the copper alloy is not suitable to withstand high loads due to inertial loading act on this reinforcement, it usually is required to anchor the reinforcement by legs made of stainless steel or copper alloy and protrude into the cooler parts of the piston.
Jedoch bringt die Herstellung solcher Kolben einige Probleme mit sich. Diese bestehen im wesentlichen darin,However, the manufacture of such pistons poses several problems. These essentially consist of
a) daß die Genauigkeit der Positionierung schwierig ist, wenn der Kolben in herkömmlicher Weise mit der Krone nach oben gegossen wird, unda) that the accuracy of the positioning is difficult when the piston is cast in a conventional manner with the crown upwards, and
b) daß die Kolbenschürze frei von Poren gehalten werden muß,b) that the piston skirt must be kept free of pores,
wenn das Gußstück mit der Krone nach unten hergestellt wird, um hierbei die genaue Positionierung der Verstärkung und der Ve-Lcinkerungsbeine zu erleichtern.when the casting is made with the crown facing down, in order to ensure the exact positioning of the reinforcement and the Ve-lengthening legs to make it easier.
Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren zur ITerstellung eines aus einer Leichtmetallegierung bestehenden Kolbens mit einer verstärkten Krone vorzuschlagen, bei dem d<m . vorerwähnte Problem des Brechens der Kolbenkrone ausgeschlossen oder im wesentlichen vermieden wird, das keine Verankerungsbeine oder zwischenmetallischen Bindungen zur Verankerung der Verstärkung mit der Kolbenlegierung erfordert und das gleichzeitig dieThe invention is based on the object of a method for IT production to propose a piston made of a light metal alloy with a reinforced crown, in which d <m. The aforesaid problem of the piston crown breaking is eliminated or essentially avoided because there are no anchoring legs or intermetallic bonds to anchor the reinforcement with the piston alloy requires and at the same time the

rnochanj sehen Eigenschaften der Hauptgußlegierung verbessert, indiiin inübesondere auch in den dünneren Teilen des Gußstückes im Prinzip keine Poren auftreten. Eine weitere Aufgabe besteht darin, einen Kolben aus einer Leichtmetallegierung zu schaffen, der eine einwandfrei verstärkte Kolbenkrone hat und die erwähnten strukturellen Eigenschaften aufweist.rnochanj see properties of the main casting alloy improved, indiiin especially in the thinner parts of the casting in principle no pores occur. Another object is to create a piston made of a light metal alloy, which has a properly reinforced piston crown and has the structural properties mentioned.
Dementsprechend besteht das Verfahren zur Herstellung eines sol1-chen Kolbens nach der Erfindung darin,Accordingly, the method for producing a sol 1 -chen piston according to the invention consists in
a) daß eine Kolbenform mit der Krone nach unten angeordnet wird, wobei, sich also der Teil der Form am weitesten unten befindet, in dem die Kolbenkrone ausgebildet wird,a) that a piston shape is arranged with the crown facing downwards, i.e. the part of the shape that is furthest down, in which the piston crown is formed,
b) driß «ine Matte aus Whiskers oder Fasern aus verstärkendem Material auf der Bodenfläche der Form aufgebracht wird, um die gesamte Fläche oder einen ausgewählten Teil oder ausgewählte Teile dieser Fläche abzudecken,b) a third mat of whiskers or fibers of reinforcing material Material is applied to the bottom surface of the mold, around the entire surface or a selected part or selected To cover parts of this area,
c) daß in die Form eine geschmolzene Masse aus einer Leichtmetallegierung gegeben wird, um die Matte zu bedecken und die Form zu füllen,c) that in the mold a molten mass of a light metal alloy is given to cover the mat and fill the mold,
d) daß auf die geschmolzene Masse in der Form ausreichend Druck ausgeübt wird, um die Oberflächenspannung zwischen der Matte und der geschmolzenen Masse zu überwinden und sicherzustellen daß die geschmolzene Masse in die Zwischenräume der Matte dringt und diese ausfüllt,d) that sufficient pressure is applied to the molten mass in the mold to reduce the surface tension between the mat and to overcome the molten mass and ensure that the molten mass is in the interstices of the mat penetrates and fills them,
e) und daß die geschmolzene Legierung in Kontakt mit der Matte aus Whiskers oder Fasern zum Erstarren gebracht wird, um ein Verbundgußstück zu bilden, bei dem die Whiskers oder Fasern in der Leichtmetallegierung eingebettet sind. 5e) and that the molten alloy is in contact with the mat of whiskers or fibers is solidified to form a composite casting in which the whiskers or Fibers are embedded in the light metal alloy. 5
Das so hergestellte Verbundgußstück wird noch maschi.ne.13 bearbeitet, um den fertigen Kolben herzustellen.The composite casting produced in this way is still machined. 13, to make the finished piston.
Der erfindungsgemäße Kolben aus einer Leichtmetallegierung mit einer verstärkten Kolbenkrone ist dadurch gekennzeichnet, daß die Verstärkung aus einer Lage oder Matte axis Whiskers oder Fasern aus verstärkendem Material besteht, die in die Leichtmetallegierung eingebettet ist und deren Zwischenräume mit die?Bor Legierung ausgefüllt sind.The piston according to the invention made of a light metal alloy with a reinforced piston crown is characterized in that the reinforcement from a layer or mat axis whiskers or fibers Made of reinforcing material that is incorporated into the light metal alloy is embedded and their interstices with the? bor Alloy are filled.
Als Leichtmetallegierung kommt vorzugsweise eine Aluminiunüegierung in Betracht, wie etwa eine Aluminium-Silizium-Legierung. Im wesentlichen reines Aluminium kann allerdings ebenfalls verwendet werden.An aluminum alloy is preferably used as the light metal alloy into consideration, such as an aluminum-silicon alloy. Substantially pure aluminum, however, can also be used will.
Die Whiskers oder Fasern bestehen zweckmäßigerweise aus Aluminiumoxyd (Al2O3) oder Siliziumkarbid (SiC). Der bevorzugte1 Durchmesser der Whiskers oder Fasern liegt in der Größenordnung von 2 bis 5 Mikrometern. Im übrigen kann die Matte nach dem Verfahren hergestellt werden, das im britischen Patent Nr.The whiskers or fibers are expediently made of aluminum oxide (Al 2 O 3 ) or silicon carbide (SiC). The preferred 1 diameter of the whiskers or fibers is in the order of 2 to 5 micrometers. Incidentally, the mat can be made by the method described in British Patent No.
1 489 34 6 beschrieben ist. V7eiterhin können auch andere hitzebeständige Oxyde, Metalle und auch Metalloide verwendet werden. Ebenso kommen auch spezielle Metalle mit hoher Festigkeit und hoher thermischer Leitfähigkeit in Betracht, wie Beryllium-Kupfe Legierungen und Kupfer-Nickel-Silizium-Bronze.1 489 34 6 is described. V7 can also use other heat-resistant Oxides, metals and also metalloids can be used. Special metals with high strength and high thermal conductivity can also be used, such as beryllium copper Alloys and copper-nickel-silicon-bronze.
Die Matte, die an der Bodenfläche der Form in Position gebracht wird, kann eine Dicke von 6 bis 10 mm und eine solche Porigkeit bzw.. Durchlässigkeit haben, daß, wenn sie von der Metallegierung durchsetzt ist, die Whiskers oder Fasern einen Anteil von 5 bis 40 Vol-%, vorzugsweise etwa 20 Vol-% ausmachen werden.The mat, which is brought into position on the bottom surface of the mold, can have a thickness of 6 to 10 mm and such porosity or .. have permeability that, if it is permeated by the metal alloy, the whiskers or fibers a proportion of 5 to 40% by volume, preferably about 20% by volume.
nie Matte liegt einfach auf der Bodenfläche der Form und wird dort von der geschmolzenen Legierung gehalten, die von oben i> iii die !'1OrIn beispielsweise bei einer Temperatur von etwa 670 bis 7400C eingegossen wird, so daß Mittel zur Lagesicherung der Matte in der Form nicht erforderlich sind. Die Matte kann sich über die gesamte Bodenfläche der Form erstrecken oder kann auch die Form eines Ringes haben, so daß der mittlere Teil der Krone, der zur Herstellung der Brennkammer maschinell entfernt wird, im wesentlichen aus der Leichtmetallegierung besteht, wählend die Verstärkung im Bereich um die Kante der Brennkammer gegeben ist. Eine solche ringförmige Matte braucht sich schließlich auch nicht bis zum äußeren Umfang der Krone hin zu erstrekken. never mat lies simply on the bottom surface of the mold and is held there by the molten alloy, which from above i> iii die! ' 1 OrIn is poured in, for example, at a temperature of about 670 to 740 0 C, so that means for securing the position of the mat in the mold are not required. The mat may extend over the entire bottom surface of the mold or it may be in the form of a ring so that the central part of the crown, which is mechanically removed to produce the combustion chamber, consists essentially of the light metal alloy, with the reinforcement in the area around the edge of the combustion chamber is given. Finally, such an annular mat does not need to extend to the outer circumference of the crown.
Auf das geschmolzene Metall kann mit Hilfe eines Kolbens oder Stempels Druck ausgeübt werden, der sich oberhalb des Hohlraumes der Form befindet. Der Kolben wird nach unten in Kontakt mit dem -geschmolzenen Metall gedrückt, wodurch das Metall nach unten durch die Zwischenräume der Matte dringt und diese ausfüllt, wobei gleichzeitig die mechanischen Eigenschaften der Legierung verbessert und die Porigkeit im Gußstück reduziert wird, und zwar insbesondere in der Kolbenschürze und anderen Teilen des Gußstückes mit dünnem Querschnitt. Der PreßdruckOn the molten metal can with the help of a piston or Stamp pressure are exerted, which is located above the cavity of the mold. The piston will make contact downwards pressed with the molten metal, causing the metal after penetrates below through the gaps in the mat and fills it, while maintaining the mechanical properties of the Alloy is improved and the porosity in the casting is reduced, in particular in the piston skirt and others Split the casting with a thin cross-section. The press pressure
TO kann in der Größenordnung von 315 bis 3150 kg/cm2 (2 bis 20 tons p.s.i.) liegen, was von der Größe des Kolbens abhängen wird. Außerdem kann die Belastung bzw. die Druckbeanspruchung über einen Zeitraum von 55 Sekunden bis zu zwei Minuten aufrechterhalten werden, was auch.wiederum von der Abmessung des jeweils zu gießenden Querschnittes abhängt.TO can be on the order of 315 to 3150 kg / cm 2 (2 to 20 tons psi), which will depend on the size of the piston. In addition, the load or the compressive stress can be maintained over a period of 55 seconds up to two minutes, which in turn depends on the dimensions of the cross-section to be cast.
Die Whiskers oder Fasern der Matte können ungeordnet oder auch so angeordnet sein, daß sie in einer besonderen Richtung orientiert sind, die eine besonders hohe Stärke bzw. Stabil Hat erfordert. Falls es erwünscht ist, könnton die Whii-.kcrs oder Fasern auch vorher auf beispielsweise 200 bis 3500C erhitzt werden.The whiskers or fibers of the mat can be disordered or arranged in such a way that they are oriented in a particular direction, which requires a particularly high strength or stability. If desired, the könnton Whii-.kcrs or fibers are also previously heated to, for example, 200 to 350 0 C.
