Abstract

The gas conduit discharging to atmosphere, partic. for IC engines, is as known. It has an open-ended hollow aluminium extrusion without transverse partitions but possibly multi-walled, and different material/alloy and closures. These embody additional partitions creating internal compartments and direct the gas flow to produce thermal gradients across the aluminium-body walls and/or between successive closures. The butting edge (61) provided on sheet steel end-closures (60) for making a positive or material-bonding joint with the Al hollow section (1) bears against the latter outer surface (66). Normally separated (62) from this edge, the closure embodies a flat bearing-zone (63).

Description

Beschreibung Diese Zusatzajuneldung zur Hauptanmeldung P 28 04 875.1 hat die Aufgabe, zwischenAußenwandung des Aluminium-Hohlprofils (66) und zwei Kontaktzonen eines etwa deckelartig darüberliegenden Schließkörpers (60) einen form-oder stoffschlüssigen Verbund herbeizuführen0 Der Gesichtspunkt der stoffschlü6sigen Werkstoffw.erbindung, bezogen auf das Stahlblech des Schließkörpers und die Aluniniumfläche (66) führt in das Gebiet der Reibschweissung. Bereits formschlüssige Verbindung wird in vielen Anwendungsfällen dadurch ausreichend sein, daß in den vier Merkmalen bzw. Verfahrensschritten des Hauptanspruches dieser Zusatzanmeldung mittels der zwei Kontaktzonen Rand (6i) undrFläche (63) verbunden mit einer Umfangminderung des Blechrandes (61) mittels Einrillung in die Aluminiumfläche eine außerordentliche Verfestigung beider Werkstücke enthalten ist. Diese Verfestigung kann gemäß Anspruch 3 durch eine Schlitzschluß-Sicherung stabilisiert werden0 Die stoffschlüssige Verbindung der Werkstoffe gemäß dem hier vorgelegten Verfahren hat den besonderen Vorzug, daß der Ausweichfluß teigigen Aluminiums in eine dafür vorgesehene Abstandzone (62) geleitet werden kann. Die zusätzliche Arbeitsoperation der Schweißgrat-Ent fernung ist dadurch entbehrlich. Außerdem bildet der (aus den Schemazeichnungen nicht ersichtliche) Materialfluß in die Abstandzone (62 in Figur i) auf der Aluminiumoberfläche (66) einen wallartigenMaterialring, der auch dann festigkeitserhöhend wirkt, wenn stoffschlüssiger Oberflächenverbund der Werkstoffe nur teilweise in den vorgesehenen Kontaktzonen (61 und 63) stattfindet0 Die Figur 1 zeigt, in welcher Weise das Anlegen eines nach in. Description This supplementary notification to the main application P 28 04 875.1 has the task of between the outer wall of the aluminum hollow profile (66) and two contact zones an approximately cover-like overlying closing body (60) has a form-fitting or material fit To bring about a bond 0 The point of view of the material bond, based on the sheet steel of the closing body and the aluminum surface (66) leads in the field of friction welding. Already form-fitting connection is used in many Applications are sufficient that in the four features or process steps of the main claim of this additional application by means of the two contact zones edge (6i) and surface (63) connected with a reduction in the circumference of the sheet metal edge (61) by means of Grooving in the aluminum surface provides an extraordinary strengthening of both workpieces is included. This solidification can according to claim 3 by a slot closure fuse are stabilized0 The material connection of the materials according to the here The method presented has the particular advantage that the bypass flow of pasty aluminum can be passed into a spacing zone (62) provided for this purpose. The additional This eliminates the need for the welding burr removal operation. It also educates the flow of material (not evident from the schematic drawings) into the spacing zone (62 in Figure i) on the aluminum surface (66) a wall-like material ring, which also has a strength-increasing effect when there is a material bond between the surfaces of the materials only partially takes place in the intended contact zones (61 and 63) 0 FIG. 1 shows the manner in which the creation of an in.

nen (etwa dur.ch einmalige Stauchung) gewölbten Blechrandes (61) an die Alu minium-Oberfläche (66) gemäß Anspruch la je'dach ist. Die Figur 2 zeigt äen Zustand nach einer ersten Abriebphase, wobei gemäß Anspruch 6 Schlitz und Scherkante (vgl.Figur 3) bis in die Zone der Kontaktfläche (63) reichen müßten.. Durch Abrieb mittels kleiner Drehzahl können hierdurch noppen artige Längsaufwölbungen (65) der Aluminium-Oberfläche (66; vgl. Figur 4) im Kont.lktbeteich abgerieben werden, sodaß Formschluß in inniger Weise auch bei solcher Konstruktionsform erreichbar ist. In der Regel wird der Drehantrieb mit dem Aluminiumkörper vorgesehen und der Schließkörper wird fest eingespannt, weil sich auf diese Weise bei einer so kalibrierten Montagelehre auch die Druckzubringung einschließlich Schlitzschluß-Sicherung einfacher auslegen läßt. Das Verfahren ist auch für reinen Rohrverbund anwendbar und beschränkt sich nicht auf die genannten Werkstoffarten0nen (about by one-time compression) arched sheet metal edge (61) the aluminum surface (66) according to claim la je'dach. Figure 2 shows Äen state after a first abrasion phase, wherein according to claim 6 slot and shear edge (see Figure 3) should extend into the zone of the contact surface (63) .. By abrasion by means of a low speed, nub-like longitudinal bulges (65) of the Aluminum surface (66; see FIG. 4) in the control pond are rubbed off so that Positive locking can be achieved in an intimate manner even with such a construction form. In As a rule, the rotary drive is provided with the aluminum body and the closing body is firmly clamped because in this way with an assembly jig calibrated in this way also make the pressure supply, including focal plane protection, simpler leaves. The method can also be used for pure pipe connections and is limited not on the named types of material0
