Um Katalysatoren mit Monolithen, d.h. Keramikträgern, zu fertigen, ist es notwendig, den Monolith im Katalysatorgehäuse gegen mechanische Beanspruchung zu schützen. Dies geschieht im allgemeinen durch eine sogenannte Bläh- oder Quellmatte, die den Monolith gegen das metallische Katalysatorgehäuse entkoppeltTo use catalysts with monoliths, i.e. Ceramic supports, it is necessary to manufacture Protect monolith in the catalytic converter housing against mechanical stress. This is generally done by a so-called swelling or swelling mat, the monolith decoupled from the metallic catalyst housing
Katalysatorgehäuse, wie sie zur Anbindung eines Katalysators in Abgasanlagen von Verbrennungskraftmaschinen, insbesondere von Kraftfahrzeugen, zum Einsatz kommen, gibt es in vielfältigen Ausführungsformen, wobei sich zwei Systeme im Markt durchgesetzt haben. Gemäß dem ersten System wird ein mit einem katalytisch wirksamen Material beschichteter Monolith (insbesondere keramische Bauform) mit einer Blähmatte umwickelt, welche die Aufgabe hat, den Monolithen zu lagern. Diese Blähmatte wird zusammen mit dem Monolithen in einen Blechmantel eingesetzt, der ebenfalls mittels eines Wickelverfahrens hergestellt wird und die Aufgabe hat, den Monolithen zusammen mit der Blähmatte in Position zu halten. Der vorgespannte Blechmantel wird anschließend an einzelnen Stellen mittels Punktschweißung geheftet Stirnseitig werden Ein- und Ausgangstrichter angebracht, die entsprechend den Anforderungen (Anbindung des Auspuffrohrs) ausgerichtet sind. Das Anbringen erfolgt mittels einer Schweißrundnaht an den gewickelten Konverter. Nach Verschließen des Blechmantels mittels einer Schweißnaht erhält man den fertigen Wickelkonverter.Catalytic converter housing, as used to connect a catalytic converter in exhaust systems from Internal combustion engines, in particular motor vehicles, are used, There are many different designs, with two systems on the market have prevailed. According to the first system, one becomes catalytic effective material coated monolith (in particular ceramic design) with a Inflatable inflatable mat wrapped, which has the task of storing the monolith. This Inflatable mat is used together with the monolith in a sheet metal jacket is also produced by means of a winding process and has the task of Keep monoliths in position together with the inflatable mat. The biased The sheet metal jacket is then tacked at individual points using spot welding On the front side, inlet and outlet funnels are attached, which correspond to the Requirements (connection of the exhaust pipe) are aligned.

Weiterhin bereitet auch die durch die Schalenform festgelegte Geometrie häufig Schwierigkeiten bei der Anpassung an den Unterboden der Kraftfahrzeuge.The second system that is established on the market is known as a shell converter from the monolith, a separate mat and two half-shells, namely one Upper and one lower shell, but there is often one in the shell converter lack of process security. Furthermore, it also prepares the bowl shape Fixed geometry often has difficulty adapting to the underbody Motor vehicles.

Das erfindungsgemäße Verfahren ist dadurch gekennzeichnet, daß der Gehäusemantel anschließend mit Spannbändern vorgespannt und während des Vorspannens mit einem ein Setzen der Blähmatte bewirkenden, direkten oder indirekten Klopfen mit einer vorbestimmten Klopffrequenz von 20 bis 80 Hz beaufschlagt wird.The method according to the invention is characterized in that the housing jacket then pretensioned with tensioning straps and with one during the pretensioning a setting of the inflatable mat causing direct or indirect tapping with a predetermined knocking frequency of 20 to 80 Hz is applied.
Durch dieses Klopfen, das bei einer Klopffrequenz von 20 bis 80 Hz, insbesondere gemäß einer vorteilhaften Ausführungsform im Bereich von 40 bis 50 Hz, beispielsweise 5 Sekunden lang durchgeführt wird, erfolgt das Setzen der Blähmatte beim Spannen des Gehäusemantels mittels der Spannbänder auf wesentlich wirkungsvollere Weise, wodurch ein absolut fester Sitz des Monolithen innerhalb des Gehäusemantels über die gesamte Lebensdauer des Katalysators sichergestellt wird.By knocking at a knocking frequency of 20 to 80 Hz, in particular according to an advantageous embodiment in the range from 40 to 50 Hz, for example Is carried out for 5 seconds, the inflatable mat is set when the Housing shell by means of the tensioning straps in a much more effective manner, which ensures an absolutely tight fit of the monolith within the casing entire life of the catalyst is ensured.
Gemäß einer vorteilhaften Ausführungsform der Erfindung wird die Blähmatte derart in den Gehäusemantel eingesetzt, daß die Blähmantelüberlappung um 180° versetzt zur Überlappung des Gehäusemantels angeordnet ist Hierdurch wird zuverlässig verhindert, daß die beiden Überlappungen übereinander zu liegen kommen, wodurch das Zuziehen der Blähmatte bzw. des Gehäusemantels beeinträchtigt werden könnte. According to an advantageous embodiment of the invention, the inflatable mat is in used the housing jacket that the expansion jacket overlap offset by 180 ° Overlap of the housing shell is arranged This reliably prevents that the two overlaps come to lie on top of each other, causing the pinch the inflatable mat or the casing shell could be impaired.
Eine besonders vorteilhafte Ausführungsform zeichnet sich dadurch aus, daß die Spannkraft zum Vorspannen des Gehäusemantels zum Ende des Klopfvorgangs hin auf 10 bis 30 kN, insbesondere 20 kN, gesteigert wird. Ein derartiges kraftgesteuertes Spannen des Gehäusemantels mit gleichzeitigem Klopfen bewirkt auf besonders wirkungsvolle Weise ein Setzen und eine feste Umhüllung der Blähmatte.A particularly advantageous embodiment is characterized in that the Clamping force for pretensioning the housing jacket towards the end of the tapping process 10 to 30 kN, in particular 20 kN, is increased. Such a force controlled Tensioning the casing with simultaneous knocking has a special effect effective setting and firm wrapping of the inflatable mat.
Gemäß einer vorteilhaften Ausführungsform wird der Gehäusemantel nach dem Vorspannen mittels Punktschweißung geheftet. An den gehefteten Gehäusemantel werden stirnseitig Trichter mittels einer Rundnaht angeschweißt, wobei die Überlappung des Gehäusemantels erst nach dem Anschweißen der Trichter mit einer Längsnaht vollständig zugeschweißt wird. Auf diese Weise läßt sich das Katalysatorgehäuse auf sehr schnelle, maßgenaue und kostengünstige Weise herstellen.According to an advantageous embodiment, the housing jacket after the Tensioning tacked using spot welding. On the stapled casing funnels are welded on the front using a round seam, the overlap of the housing shell only after welding the funnels with a longitudinal seam is completely welded shut.
