Description

Verfahren zur Herstellung von Ventilsteuerungsknaggen durch Verbundguß Die Erfindung betrifft ein Verfahren zur Herstellung von Ventilsteuerungsknaggen durch Verbundguß, welches sich im wesentlichen dadurch kennzeichnet, daß der mit Vorsprüngen, Haken oder Löchern versehene rohrförmige Teil der aus Stahl bestehenden Stange zur Herstellung der Platte mit Gußeisen umgossen wird, das während des Erstarrens an einer in der Gußform angebrachten Metalleinlage gehärtet wird.Process for the production of valve control lugs by composite casting The invention relates to a method for producing valve control lugs by composite casting, which is essentially characterized in that the with Tubular part of those made of steel and provided with protrusions, hooks or holes Rod for the production of the plate is encased with cast iron, which during solidification is hardened on a metal insert attached to the mold.

Das Umgießen rohrförmiger Körper mit Metall zur Bildung von Flanschen o. dgl. ist an und für sich bekannt. Ferner ist es bekannt, den in das anzugießende Metall hineinragenden Rohrteil zur Erleichterung der Verbindung mit Vorsprüngen zu versehen, und außerdem ist es bekannt, die Härtung von Außenteilen an Gußstücken durch Verwendung :entsprechender metallischer Einlagen in. der Gußform zu bewirken.The casting of metal around tubular bodies to form flanges or the like is known in and of itself. It is also known to cast the in the Metal protruding pipe part to facilitate connection with protrusions to provide, and also it is known, the hardening of outer parts on castings by using: appropriate metallic inlays in the casting mold.

Die Erfindung besteht darin, daß diese drei an und für sich bekannten Maßnahmen initeinander vereinigt werden, um Ventilsteuerungsknaggen herzustellen. Es werden nach dem neuen Verfahren Ventilsteuerungsknaggen hergestellt, die sehr leicht sind und hinsichtlich des Teiles, der mit der Nockenwelle in Berührung kommt, eine sehr große Härte besitzen.The invention consists in that these three are known per se Measures are combined with one another to produce valve control lugs. Valve control lugs are produced using the new process, which are very are light and in terms of the part that comes into contact with the camshaft, have a very great hardness.

Die Zeiclinung stellt eine Ausführungsform des Erfindungsgegenstandes b;eispielsweise.dar. Die Knagge besteht aus einer Hohlstange i, die an einem ihrer Enden mit der Aussparung z für die Regulierschraube versehen ist. Bei 3 ist die ,Bohrung der Stange ihrer ,ganzen Länge nach :erweitert, um eine möglichst dünne Wandung i und somit ein sehr leichtes Gewicht zu erhalten. Eine Platte q. aus anderem Metall, deren Fläche 5 besonders hart sein muß, ist um die Stanfg e i herumgegossen. Zu diesem Zwecke wird die hohle Stange i zweckmäßig in eine Form gebracht, die aus mehreren Teilen besteht, von denen der eine, welcher der Fläche 5 .entspricht, notwendigerweise metallisch ist, an der infolgedessen das flüssige Metall sehr schnell abgekühlt wird und demgemäß an dieser Stelle eine große Härte erhält.The drawing represents an embodiment of the subject matter of the invention b; for example .ar. The catch consists of a hollow rod i, which is attached to one of their Ends with the recess z for the regulating screw. At 3 is the , Bore of the rod along its entire length: enlarged to be as thin as possible Wall i and thus a very light weight. A plate q. from other Metal, the surface 5 of which must be particularly hard, is cast around the stem. For this purpose, the hollow rod i is expediently brought into a shape that consists of consists of several parts, of which the one which corresponds to the area 5., necessarily is metallic, at which the liquid metal is cooled very quickly as a result and is accordingly given a great hardness at this point.

Der Teil der Stange i, der in das flüssige Metall eingetaucht wird, wird vorher mit seiner Schicht aus Nickel, Zinn oder irgendeinem anderen Stoff überzogen, -welcher ein Abstoßen des flüssigen Metalls bei der Berührung nmit der Stange verhindert, so daß man also :ein vollkommenes Anhaften erzielt.The part of the rod i that is immersed in the liquid metal, is previously covered with its layer of nickel, tin or any other substance, -which prevents the molten metal from being repelled when it comes into contact with the rod, so that one thus: achieves perfect adherence.

Das Ende der Stange i, welches in die Platte q. eingesetzt wird, wird etwas ausgebaucht oder wird mit deiner Auskehlung oder mit Löchern versehen, welche eine gute Verbindung der beiden Metalle ermöglichen.The end of the rod i which goes into the plate q. is used something bulged or is provided with your groove or with holes, which enable a good bond between the two metals.

Bei dem in der Zeichnung veranschaulichten Beispiel ist eine Anzahl von Ansätzen 6 vorgesehen, um die Verbindung im Augenblicke des Aufschmnelzens der Platte q. auf der Stange i zu erleichtern.In the example illustrated in the drawing, is a number provided by lugs 6 to the connection at the moment of melting the Plate q. to facilitate on the pole i.
