Abstract
Description
Die Erfindung betrifft ein Verfahren zur Herstellung eines gekühlten Ringträgers für einen Aluminiumkolben nach dem Oberbegriff des Anspruches 1.The invention relates to a method to produce a chilled Ringbearer for one Aluminum pistons according to the preamble of claim 1.
Aus der
Nachteilig ist hierbei, dass es einen sehr großen fertigungstechnischen Aufwand erfordert, Kühlkanäle durch Verbiegen dafür vorgesehener Bleche und Ringträger durch Verbiegen länglicher, im Strangpressverfahren hergestellter Profileisen herzustellen. Außerdem bietet die Methode, einen Kühlkanal alleine dadurch abzudichten, dass das Ende des diesen Kühlkanal ergebenden Blechteiles unter Krafteinwirkung auf ein profiliertes Werkstück gedrückt wird, keinesfalls eine ausreichende Gewähr dafür, dass der Kühlkanal bei der Herstellung des Kolbens im Verbundgussverfahren unter Verwendung der separat hergestellten Ringträger-Kühlkanal-Kombination dicht genug ist, damit beim Gießen keine Schmelze in den Kühlkanal eindringt.The disadvantage here is that there is one very big Manufacturing engineering requires cooling channels by bending intended Sheets and ring supports by bending elongated, to produce profile iron manufactured in the extrusion process. Moreover offers the method of a cooling duct seal only by having the end of this cooling channel resulting sheet metal part under the force of a profiled workpiece depressed is in no way a sufficient guarantee that the cooling duct in the manufacture of the piston using the composite casting process the separately manufactured ring carrier-cooling channel combination tight enough is so that when pouring none Melt in the cooling channel penetrates.
Hiervon ausgehend liegt der Erfindung die Aufgabe zugrunde, ein einfaches und problemlos realisierbares Verfahren zur Herstellung eines qualitativ hochwertigen, gekühlten Ringträgers zu schaffen.The invention is based on this based on the task, a simple and easy to implement Process for the production of a high quality, cooled ring carrier create.
Gelöst wird diese Aufgabe mit den Merkmalen nach dem Kennzeichen des Hauptanspruches.This task is solved with the Features according to the characteristic of the main claim.
Zweckmäßige Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche.Useful embodiments of the invention are the subject of the subclaims.
Der erfindungsgemäße Kühlkanal ist mit einfachen und problemlos realisierbaren Verfahrensschritten herstellbar. Zudem wird eine verbesserte Kühlwirkung des an den Ringträger angeformten Kühlkanals dadurch erreicht, dass zum einen sowohl der Ringträger als auch der Kühlkanal in einen gemeinsamen Metallring eingearbeitet sind. Zum anderen ergibt die Verwendung von Aluminium für die dem Feuersteg zugewandte Flanke der Ringträgernut eine weitere Verbesserung der Kühlwirkung seitens des an den Ringträger angeformten Kühlkanals.The cooling duct according to the invention is simple and Process steps that can be easily implemented. moreover will have an improved cooling effect of the ring bearer molded cooling channel achieved in that both the ring carrier and also the cooling channel are incorporated into a common metal ring. On the other hand results in the use of aluminum for those facing the top land Flank of the ring carrier groove one further improvement of the cooling effect on the part of the ring bearer molded cooling channel.
Anhand der Zeichnungen wird das erfindungsgemäße Verfahren zur Herstellung eines gekühlten Ringträgers näher beschrieben. Es zeigenThe method according to the invention is illustrated in the drawings to produce a chilled Ringbearer described in more detail. Show it
