Description

Blechkrümmer für Verbrennun-qsmotorenSheet metal bend for internal combustion engines

Die Erfindung betrifft minen Blechkrümmer für Verbrennungsmotoren, welcher aus zwei Halbschalen aus Dppelblech besteht, die entlang bzw. zwischen den ausgewölbten Kanalteilen Borde bzw. Anlageflächen bilden, längs denen bzw. im Bereich derselben sie miteinarder verheißt sind.The invention relates to mine sheet metal manifolds for internal combustion engines, which consists of two half-shells made of double sheet metal, which run along or between the Arched channel parts form borders or contact surfaces, along which or in the area the same they are promised together.

Derartige, aus einem Doppelblech geformte Blechkrümmer sind vielfach, beispielsweise aus der deutschen Offerlegungsschrift 29 35 925 bekannt.Such sheet metal bends formed from a double sheet are often for example from the German offer specification 29 35 925 known.

Insbesondere durch die Verschweißung im Bereich ihrer A lageflächen bilden sie eine B@ueinheit mit hoher Verformungsstabilität unter Hitzeinwirkung.In particular due to the welding in the area of their A location surfaces they form a structural unit with high deformation stability under the influence of heat.

Die Verarbeitung von Doppelblech ermöglicht die weitgehende Unterdrückung von Körperschall.The processing of double sheet enables extensive suppression of structure-borne noise.

Der vorliegenden Erfindung liegt die Aufgabe zugrun@ die wärmeisolierenden Eigenschaften eines derartigen Blechkrümmers zu verbessern.The present invention is based on the object @ the heat insulating To improve properties of such a sheet metal bend.

Diese Aufgabe wird erfindungigerr;äß dadurch selöst, - daß jede Halbschale aus einem Innenblech und einem im Vergleich dazu dünneren Außenblech zusammengesetzt ist, - daß. im Bereich der Kanal teile zwischen Innen- und Außenblech ein durch Wandöffnungen des Außenblechs mit der Umgebung verbundener Hohlraum gebildet ist und - daß Innen- und Außenb4ech durch die die Halbschalen verbindenbe Schweißung miteinander verbunden sind.This task is achieved according to the invention in that each half-shell composed of an inner sheet and a comparatively thinner outer sheet is - that. in the area of the duct part between the inner and outer sheet Wall openings of the outer sheet with the environment connected cavity is formed and - that the inner and outer beakers are connected by the welding that connects the half-shells are connected to each other.

Die Wand öffnungen sind dabei bevorzugt durch Ausstanzungen im Bereich der Borde bildenden Ränder des AußenbAechs gebildet, so daß beim Verschweißen des Außenblechs mit dem Irinenblech entsprechende Offnungen im Bereich der Borde bzw.The wall openings are preferably cut out in the area of the borders forming the borders of the outer surface, so that when the Outer sheet with the irine sheet corresponding openings in the area of the shelves or

Anlageflächen verbleiben. Diese ermöglichen eine Belüftung des Hohlraums zwischen Innen- und Außenblech und damit eine optimale Kühlung der beiden Blechmäntel beider Halbschalendes Blechkrümmers.Contact surfaces remain. These allow ventilation of the cavity between the inner and outer sheet and thus optimal cooling of the two sheet metal jackets both half-shells of the sheet metal elbow.

Es genügt, wenn die Blechstärke des Außenblechs 1/2 bis 2/3 von derjenigen des Innenblechs beträgt. Auf diese Weise aelingt es, Gewicht und Material zu sparen, da die den Hohlraumquerschnitt bildenden BlechTXäntel zusammen eine höhere Forrnstabilität ergeben als beim bekannten Blechkrümmer das ohne Hohlraum verarbeitete Doppelblech.It is sufficient if the sheet thickness of the outer sheet is 1/2 to 2/3 of that of the inner sheet. In this way it is possible to save weight and material, since the sheet metal sheaths forming the cavity cross-section together have a higher form stability result than with the known sheet metal bend, the double sheet processed without a cavity.

Im Rahmen der Erfindung läßt sich eine weitere Einsparung bei der Herstellung des Blechkrümmers dadurch erzielen, daß die beiden Blechmantel jeder Halbschale nicht gesondert miteinander verschweißt erden, sondern daß diese Verschweißung gleichzeitig mit der Schweißverbindung der beiden Halbschalen erfolgt.In the context of the invention can be a further saving in the Achieve production of the sheet metal bend in that the two sheet metal jacket each Do not earth the half-shell separately but weld it together takes place simultaneously with the welded connection of the two half-shells.
