Description
Die Erfindung betrifft ein Verfahren zum Herstellen von Schalldämpfern für Kraftfahrzeuge mit Verbrennungsmotor gemäß dem Oberbegriff des Anspruchs 1.The The invention relates to a method for producing silencers for motor vehicles with internal combustion engine according to the preamble of claim 1.
Es gibt zwei Typen von Schalldämpfergehäusen: die Schalengehäuse, bestehend aus zwei tiefgezogenen Blechschalen, und die Wickelgehäuse, bestehend aus einer Blechplatine, die zu einem Zylinder gerollt wird und deren Enden gasdicht verschlossen werden.It There are two types of muffler housings: the Shell casing consisting of two deep-drawn sheet metal shells, and the winding housing, consisting from a sheet metal plate, which is rolled into a cylinder and whose Ends are sealed gas-tight.
Die vorliegende Erfindung betrifft die letzt genannten Wickelgehäuse.The The present invention relates to the last-mentioned winding housings.
Schalldämpfer besitzen neben einem Gehäusemantel ein Einlassrohr und ein Auslassrohr für die Abgase, stirnseitige Endbleche oder -konen und akustisch wirksame Einbauten, beispielsweise Zwischenwände, Überströmrohre und dergleichen. Stirnwände bzw. -konen und Einbauten müssen zunächst in der richtigen Position gehalten werden, bis die den Gehäusemantel bildende Blechplatine aufgewickelt und verschlossen wurde. Danach müssen die Stirnbleche bzw. -konen und die akustisch wirksamen Einbauten befestigt werden. Während dies bei den Stirnblechen und -konen noch ohne großen Aufwand möglich ist, ist die Situation bei den Einbauten sehr viel schwieriger, weil das Innere des Gehäuses nicht mehr zugänglich ist. Etwaige Schweißverbindungen müssen daher „blind” angefertigt werden.Own silencer next to a housing shell an inlet pipe and an outlet pipe for the exhaust gases, end-side End sheets or cones and acoustically effective internals, for example Intermediate walls, overflow pipes and like. end walls or -konen and fixtures must first in be held in the correct position until the housing shell forming sheet metal plate was wound and sealed. After that have to the front plates or cones and the acoustically effective internals be attached. While This is still possible with the front plates and cones without much effort, the situation with the internals is much more difficult because the interior of the case no longer accessible is. Any welds must therefore be made "blind" become.
Um die exakte Positionierung der Zwischenwände sicher zu stellen, werden im Gehäusemantel häufig umlaufende parallele Nuten vorgesehen. Das Aufwickeln von Blechplatinen, die mit solchen Nutenpaaren ausgerüstet sind, gestaltet sich jedoch einigermaßen aufwändig. Das ist unbefriedigend.Around to ensure the exact positioning of the partition walls in the housing shell often encircling provided parallel grooves. The winding of sheet metal blanks, the equipped with such pairs of grooves are, but it is reasonably expensive. That is unsatisfactory.
Der vorliegenden Erfindung liegt die Aufgabe zugrunde, ein Verfahren anzugeben, mit dessen Hilfe Schalldämpfer für Kraftfahrzeuge mit Verbrennungsmotoren sehr viel einfacher, schneller und vor allem exakter hergestellt werden können.Of the The present invention is based on the object, a method specify, with the help of silencer for motor vehicles with internal combustion engines made much easier, faster and, above all, more accurate can be.
Diese Aufgabe wird gelöst durch ein Verfahren mit den Merkmalen des Anspruchs 1.These Task is solved by a method having the features of claim 1.
Das erfindungsgemäße Verfahren verwendet zur Formgebung des Gehäusemantels ein Verfahren, bei dem ein elastischer Kern in das zu verformende Blechteil eingesetzt wird. Der Kern muss jedoch nicht über das gesamte Gehäuse elastisch ausgeformt sein. Es genügt eine elastische Ausformung des Kerns über die zu verformenden Bereiche. Durch diese Materialersparnis reduzieren sich die Herstellungskosten für dieses Verfahren.The inventive method used to shape the housing shell a method in which an elastic core in the deformed Sheet metal part is used. The core, however, does not have that entire housing be elastically formed. It suffices an elastic shape of the Kerns about the areas to be deformed. Reduce this material savings the production costs for This method.
Das Blechteil selbst sitzt in einer druckfesten Form, die eine Innenkontur besitzt, die dem späteren Aussehen des Gehäusemantels entspricht. Insbesondere besitzt die Form Hohlräume an den Stellen, an denen eine Ausstülpung gewünscht ist, die durch Abschneiden des Deckels die Funktion eines Einlassstutzens oder Auslassstutzens übernehmen kann. Dabei ist von besonderem Vorteil, dass derartige Ausstülpungen an praktisch jeder beliebigen Stelle des Gehäusemantels in beliebiger Form (z. B. als Konus) mit großer Genauigkeit und geringen Toleranzen erzeugt werden können, und zwar auch dort, wo dies mit der herkömmlichen Technik nicht oder nur mit großem Aufwand möglich ist. Die geöffnete Ausstülpung kann auch zum Einführen eines Rohres, z. B. zum Anschluss an den Einlass- oder Auslassstutzen verwendet werden.The Sheet metal part itself sits in a pressure-resistant form, which has an inner contour owns the later appearance of the housing jacket equivalent. In particular, the shape has cavities at the locations where a protuberance required is that by cutting the lid, the function of an inlet nozzle or outlet can take over. It is of particular advantage that such protuberances at virtually any point of the housing shell in any form (eg as a cone) with large Accuracy and low tolerances can be generated, and Although this is not the case with conventional technology only with big Effort possible is. The opened one protuberance can also be used for insertion a pipe, z. B. for connection to the inlet or outlet port be used.
Ein weiterer Vorteil besteht darin, dass die akustisch wirksamen Einbauten in den schon fertig geformten, jedoch noch nicht verschlossenen Gehäusemantel bequem eingeschoben werden können. Da der Gehäusemantel noch offen ist, kann der exakte Sitz der Einbauten problemlos kontrolliert und justiert werden. Sobald die offenen Enden des Gehäusemantels verschlossen werden, sitzen die Einbauten fest und der Schalldämpfer ist fertig.One Another advantage is that the acoustically effective internals in the already formed, but not yet closed housing jacket can be inserted easily. There the housing jacket is still open, the exact fit of the internals can be easily controlled and adjusted. Once the open ends of the housing shell be closed, the internals are stuck and the muffler is finished.
Das Schließen des Gehäusemantels kann auf mehrere Arten geschehen. Geeignete Verfahren sind das Schweißen, das Löten, das Kleben und das Falzen.The Shut down of the housing jacket can be done in several ways. Suitable methods are welding, the Soldering, gluing and folding.
Durch eine reliefartige Ausgestaltung der Innenkontur der Form können in den Gehäusemantel nicht nur Ausstülpungen, sondern auch Vertiefungen und Erhöhungen, beispielsweise zum Halten der Zwischenwände oder zum Reduzieren der Schallabstrahlung von der Gehäuseoberfläche. eingeformt werden. Ein ungünstig ausgestalteter Bauraum kann ohne einen zusätzlichen Arbeitsgang ausgenützt werden.By a relief-like configuration of the inner contour of the mold can in not the housing shell only protuberances, but also depressions and elevations, for example to Holding the partitions or to reduce the sound radiation from the housing surface. molded become. An unfavorable designed space can be exploited without an additional operation.
Gemäß einer Ausgestaltung der Erfindung werden beim Schließen der Form die Enden der Blechplatine überlappt. Auf diese Weise entsteht ausreichend Fläche, um den Gehäusemantel dicht verschließen zu können.According to one Embodiment of the invention, the ends of the sheet metal blank are overlapped when closing the mold. In this way, sufficient surface area is created around the housing shell close tightly to be able to.
Gemäß einer Alternative hierzu werden die freien Kanten der Blechplatine durch die Form eingeklemmt und gehalten, so dass sie sich beim anschließenden Pressvorgang nicht verziehen können. Dadurch entstehen zwei parallele Flansche, die das Verschließen nicht nur mittels Schweißen, Löten oder Kleben sondern auch mittels mechanischem Verschließen, z. B. Falzen, ermöglichen.According to one Alternative to this, the free edges of the sheet metal blank by the mold is clamped and held, so that they are in the subsequent pressing process can not forgive. This results in two parallel flanges that not only closing by welding, Soldering or gluing but also by mechanical closure, z. B. folding, allow.
Anhand der Zeichnung soll die Erfindung in Form zweier Ausführungsbeispiele näher erläutert werden. Es zeigen jeweils rein schematisch und als AnsichtReference to the drawing, the invention is explained in more detail in the form of two embodiments become.
