Abstract
Description
Die Erfindung betrifft ein Mehrkanalrohr, das ein Außenrohr aufweist, in dessen Innenraum mindestens ein Einsatzelement zur Ausbildung mindestens zweier Durchgangskanäle eingesetzt ist, sowie ein Verfahren zu seiner Herstellung.The The invention relates to a multi-channel tube, which is an outer tube has, in the interior of which at least one insert element for Training at least two passageways used is, as well as a method for its production.
Derartige Mehrkanalrohre werden insbesondere als Wärmetauscher oder als medienzuführende Leitungen in Anlagen oder Geräten verwendet. Insbesondere bei medienzuführenden Leitungen ist es erforderlich, an deren Enden Anschlüsse oder Kupplungen vorzusehen, um damit das Mehrkanalrohr an die Anlage oder das Gerät anschließen oder ankuppeln zu können. Zur Herstellung derartiger Anschlüsse oder Kupplungen ist in der Regel eine Bearbeitung des Mehrkanalrohrs auf Drehmaschinen bzw. spanenden Bearbeitungszentren unumgänglich. Hierbei kann ein Verdrehen der axial verlaufenden Rohre nicht ausgeschlossen werden. Dies besitzt den Nachteil, dass die Anschlussmöglichkeiten erschwert und/oder die Durchgängigkeit der Durchgangskanäle behindert wird.such Multi-channel pipes are used in particular as a heat exchanger or as media-feeding lines in systems or devices used. Especially with media-feeding lines It is necessary at their ends connections or couplings to provide so that the multi-channel pipe to the plant or the device to connect or to be able to connect. For the production Such connections or couplings is usually a processing of the multi-channel tube on lathes or cutting Machining centers inevitable. This can be a twist the axially extending tubes are not excluded. This has the disadvantage that the connection options difficult and / or impeded the continuity of the passageways becomes.

Es ist Aufgabe der vorliegenden Erfindung, ein Mehrkanalrohr der eingangs genannten Art sowie ein Verfahren zur deren Herstellung derart weiterzubilden, dass eine erhöhte Verdrehsicherheit des oder der im Außenrohr aufgenommenen Einsatzelemente gegeben ist.It Object of the present invention, a multi-channel tube of the above mentioned type and a method for their preparation in such a way, that an increased resistance to rotation of or in the outer tube recorded insert elements is given.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass das Außenrohr an seiner Innenwand mindestens eine Vertiefung aufweist, dass das Einsatzelement mindestens einen Vorsprung aufweist, und dass die oder mindestens eine der Vertiefungen des Außenrohrs zusammen mit dem oder einen der Vorsprünge des Einsatzelements mindestens eine Presspassung ausbilden.These The object is achieved according to the invention that the outer tube on its inner wall at least one Recess, that the insert element at least one projection and that or at least one of the recesses of Outer tube together with the or one of the projections of the insert element form at least one press fit.
Das erfindungsgemäße Verfahren sieht vor, dass das Einsatzelement in den Innenraum des an seiner Innenwand mindestens eine Vertiefung aufweisenden Außenrohrs eingebracht wird, und dass durch einen Ziehvorgang mindestens eine Presspassung zwischen mindestens einer Vertiefung des Außenrohrs und mindestens einem radial vorspringenden und mit Übermaß gefertigten Vorsprung des Einsatzelements hergestellt wird.The inventive method provides that the Insert element in the interior of at least on its inner wall a recess having outer tube is introduced, and that by a pulling operation at least one press fit between at least one recess of the outer tube and at least a radially projecting and oversized Projection of the insert element is made.
Durch die erfindungsgemäßen Maßnahmen wird in vorteilhafter Art und Weise ein Mehrkanalrohr geschaffen, welches sich dadurch auszeichnet, dass die Verbindung zwischen dem Außenrohr und dem in ihm aufgenommenen Einsatzelement nicht – wie bei den bekannten Mehrkanalrohren – durch eine durch unterschiedliche Werkstoffhärten hervorgerufene formschlüssige Verbindung ausgebildet wird, sondern dass das Einsatzelement und das dieses aufnehmende Außenrohr über Presspassungen dicht und verdrehsicher miteinander verbunden sind. Es ist somit nicht mehr erforderlich, dass das Außenrohr und das in ihm eingesetzte Einsatzelement unterschiedliche Härtegrade aufweisen, damit durch ein Eindringen der Vorsprünge des Einsatzelements in die Innenwand des Außenrohrs dichte Durchgangskanäle ausgebildet werden. Die durch die Presspassungen hervorgerufene Verdrehsicherung des Einsatzelements im Außenrohr bewirkt in vorteilhafter Art und Weise, dass an das erfindungsgemäße Mehrkanalrohr leicht Anschlüsse oder Kupplungen angebracht werden können.By the measures according to the invention will created in an advantageous manner, a multi-channel tube, which characterized by the fact that the connection between the outer tube and the inserted therein insert element not - like in the known multi-channel pipes - by one by different Material hardening caused positive locking Connection is formed, but that the insert element and this receiving outer tube via press-fits tight and non-rotatably connected. It is thus no longer required that the outer tube and the in he insert element used different degrees of hardness have, so by penetration of the projections of the Insert element in the inner wall of the outer tube density Through channels are formed. The by the press fits caused rotation of the insert element in the outer tube causes in an advantageous manner that the inventive Multi-channel pipe easily attached connections or couplings can be.
Eine vorteilhafte Weiterbildung der Erfindung sieht vor, dass in das erste Einsatzelement mindestens ein zweites Einsatzelement eingesetzt und die beiden Einsatzelemente durch Presspassungen miteinander verbunden sind. Eine derartige Maßnahme besitzt den Vorteil, dass hierdurch auch eine Verdrehsicherung zwischen dem ersten und dem zweiten Einsatzelement ausgebildet ist.A advantageous development of the invention provides that in the first insert element at least a second insert element used and the two insert elements by press-fitting with each other are connected. Such a measure has the advantage that thereby also a rotation between the first and is formed the second insert element.
Eine weitere vorteilhafte Weiterbildung der Erfindung sieht vor, dass mindestens ein Einsatzelement als Innenrohr ausgebildet ist.A further advantageous embodiment of the invention provides that at least one Einsatzele Ment is designed as an inner tube.
Weitere vorteilhafte Weiterbildungen der Erfindung sind Gegenstand der Unteransprüche.Further advantageous developments of the invention are the subject of the dependent claims.
Weitere Einzelheiten und Vorteile der Erfindung sind dem Ausführungsbeispiel zu entnehmen, dass im Folgenden anhand der Figuren beschrieben wird.
