Abstract
Description
Die Erfindung betrifft ein Verbundprofil mit einem Tragkörper aus einem Leichtmetallwerkstoff als Profilkomponente und wenigstens einer mit diesem während eines Strangpreßvorganges als Oberflächenbeschichtung metallisch verbundenen weiteren Profilkomponente, insbesondere einem Profilband aus einem anderen Metall. Zudem erfaßt die Erfindung ein Verfahren zur Herstellung eines Verbundprofiles aus zwei Profilkomponenten.The invention relates to a composite profile with a support body made of a light metal material as a profile component and at least one with it during an extrusion process metallically bonded as a surface coating further profile component, in particular a profile band from a different metal. The invention also covers a method for producing a composite profile two profile components.
Der DE-PS 24 32 541 der Anmelderin ist ein Verfahren zum Herstellen von Stromschienen aus einem Trägerprofil und mindestens einer wenigstens einen Teil der Oberfläche des Trägerprofils bildenden Auflage aus Profilband eines anderen Metalls zu entnehmen. Während eines Strangpreßvorganges wird das Trägerprofil durch Auspressen eines Blockes durch den Formgebungsquerschnitt einer Matrize erzeugt, und gleichzeitig durchläuft das Profilband zur Matrizenlängsachse parallel den Matrizendurchbruch oder Formgebungsquerschnitt. Zur Lösung der Aufgabe, eine ausreichende Verbindung zwischen Trägerprofil und Profilband auch bei Verwendung nicht vorplattierter Bänder zu gewährleisten und zudem eine besonders wirtschaftliche Herstellung zu ermöglichen, werden nach der Vorerfindung mindestens zwei Verbundprofile gleichzeitig hergestellt, wobei die mit den Auflagen zu versehenden Bereiche der Trägerprofile einander gegenüberstehen und zwischen diesen die Profilbänder paarweise aufeinanderliegend durch den Formgebungsquerschnitt geführt werden. DE-PS 24 32 541 of the applicant is a method for Manufacture of busbars from a support profile and at least a part of the surface of the Carrier profile-forming support from another's ribbon Remove metal. During an extrusion process is the carrier profile by pressing out a block generates the shaping cross section of a die, and at the same time, the profile strip runs through to the longitudinal axis of the die parallel to the die opening or shaping cross section. To solve the task, an adequate Connection between support profile and profile tape also at Ensure the use of non-pre-clad tapes and to also enable particularly economical production, become at least two after the invention Composite profiles produced simultaneously, with the Areas of the support profiles to be provided with each other face each other and between them the profile strips in pairs lying on top of each other through the shaping cross section be performed.
In Kenntnis dieses Standes der Technik hat sich der Erfinder das Ziel gesetzt, die Verbindung zwischen Trägerprofil und Profilband unter Beibehaltung der besonderen wirtschaftlichen Herstellungsmöglichkeiten weitergehend zu verbessern.The inventor was aware of this state of the art set the goal, the connection between beam profile and profile tape while maintaining the special economic Manufacturing opportunities further improve.
Zur Lösung dieser Aufgabe führt die Lehre der unabhängigen
Patentansprüche 1, 11 oder 12; die Unteransprüche geben günstige Weiterbildungen
an.The teaching of the independent leads to the solution of this
Erfindungsgemäß weist das Profilband an zumindest einer seiner Längskanten von seiner tragkörperseitigen Innenfläche in Abstand zueinander abragende Ausformungen auf, welche in den Tragkörper eingebettet sind. Dabei sollen die Ausformungen hinterschnittene Zwischenräume begrenzen, welche vom metallischen Werkstoff des Tragkörpers formschlüssig ausgefüllt sind.According to the invention, the profile strip has at least one its longitudinal edges from its inner surface on the supporting body protruding formations at a distance, which are embedded in the support body. The should Formations limit undercut gaps, which from the metallic material of the support body are filled out.
Auch liegt es im Rahmen der Erfindung, daß an der dem Tragkörper zugewandten Innenfläche des Profilbandes zumindest ein Zusatzelement festgelegt und in den Tragkörper eingebettet ist; die Zusatzelemente sollen an das Profilband bevorzugt angeschweißt sein und gegebenenfalls einen hinterschnittenen Raum begrenzen, der -- wie oben erwähnt -- vom metallischen Werkstoff des Tragkörpers formschlüssig ausgefüllt wird.It is also within the scope of the invention that on the support body facing inner surface of the profile strip at least an additional element fixed and embedded in the support body is; the additional elements should be preferred to the profile tape be welded and, if necessary, an undercut Limit space that - as mentioned above - from metallic material of the support body with a positive fit is filled out.
Auf der dem Trägerprofil zugewandten Profilbandseite (Verbundseite) werden also weitere Profile, Bänder, quergestanzte Profile und Bänder, Bolzen oder ankerförmige Ausbildungen -- vorzugsweise in Edelstahl -- durch Widerstandsrollnahtschweißen, Schießbolzenschweißen oder sonstige kontinuierlich oder punktförmig wirkende Schweißverfahren bzw. Nichtschweißverbindungen wie Durchsetzverfahren, Stanzen, Verzahnen oder Verklebungen fest mit dem Profilband verbunden. Dadurch wird nach dem Verpressen zusätzlich zur metallischen Bindung des Stahlbandes dieses mechanisch durch Kraft und Formschluß im Trägerprofil verankert.On the profile strip side facing the carrier profile (Composite side) are therefore further profiles, strips, cross-cut profiles and strips, bolts or anchor-shaped Training - preferably in stainless steel - through resistance roller seam welding, Shooting Stud Welding Or other continuous or spot welding processes or non-welded connections such as penetration processes, Punching, gearing or gluing firmly with the Ribbon connected. This will add additional after pressing for the metallic binding of the steel strip mechanically anchored in the carrier profile by force and positive locking.
Dank dieser Maßgaben ergibt sich eine doppelte Sicherung der dauerhaften Verbindung beider Profilkomponenten, nämlich zum einen die metallische Verbindung zwischen Leichtmetallwerkstoff bzw. Trägerprofil und Profilband sowie zum anderen der formschlüssige Verbund an den Ausformungen. Diese Art der Bindung bleibt auch dann erhalten, wenn bereichsweise jene metallische Verbindung fehlen oder schwach ausgefallen sein sollte.Thanks to these provisions, there is a double backup the permanent connection of both profile components, namely on the one hand the metallic connection between Light metal material or carrier profile and profile tape as well on the other hand, the positive connection to the formations. This type of binding is retained even if in certain areas those metallic connections are missing or should have been weak.
Als günstig hat es sich zudem erwiesen, die Ausformungen wenigstens teilweise in einem Winkel zur Längsachse des Profilbandes zu stellen, bevorzugt in Preßrichtung einwärts geneigt; diese Maßgabe verinnigt den Formschluß.It has also proven to be advantageous to have the formations at least partially at an angle to the longitudinal axis of the To provide profile tape, preferably inward in the pressing direction inclined; this requirement internalizes the form fit.
Nach einem weiteren Merkmal der Erfindung ragt von der Innenfläche des Profilbandes zwischen seinen Längskanten in Abstand zu diesen wenigstens eine Reihe von Ausformungen ab zur Unterstützung des Verbundes.According to a further feature of the invention protrudes from the inner surface of the profile strip between its longitudinal edges in Distance from these at least a number of forms to support the association.
Vorteilhafterweise können die Ausformungen zur Innenfläche des Profilbandes geneigt sein, gegebenenfalls entstehen so zwei unterschiedliche Neigungsrichtungen.Advantageously, the formations to the inner surface of the profiled belt must be inclined, if so arise two different directions of inclination.
Bei einer weiteren Ausgestaltung der Erfindung ist am Profilband parallel zu dessen Längskanten als Zusatzelement wenigstens ein Drahtorgan festgelegt, bevorzugt ein Runddraht in Profilmittelachse angeschweißt. Oder es wird am Profilband wenigstens ein Rinnenprofil so angebracht, daß dessen Rinnenschenkel von der Innenfläche des Profilbandes bzw. der Unterseite des Stahlbandes weg gerichtet sind. In a further embodiment of the invention is on the profile band parallel to its longitudinal edges as an additional element fixed at least one wire organ, preferably one Round wire welded in the central axis of the profile. Or it will at least one channel profile attached to the profile tape, that its gutter leg from the inner surface of the profile strip or the underside of the steel strip directed away are.
Erfindungsgemäß können zudem diese Rinnenschenkel in einem Winkel zur Innenfläche verlaufen, insbesondere nach außen --also von den Profillängskanten weg -- geneigt sein.According to the invention, these gutter legs can also be in one Angles run to the inner surface, especially to the outside - so away from the longitudinal edges of the profile - be inclined.
Als günstig hat es sich auch erwiesen, in den Schenkeln Ausnehmungen vorzusehen, vor allem Randausnehmungen, die von Abschnitten der Rinnenschenkel begrenzt werden.It has also proven to be cheap in the thighs Provide recesses, especially marginal recesses that be limited by sections of the gutter legs.
Ein anderes Ausführungsbeispiel enthält an das Stahlband angeschweißte Bolzen als Ankerorgane.Another embodiment includes on the steel band welded bolts as anchor elements.
Ein erfindungsgemäßes Verfahren zur Herstellung des Verbundprofiles zeichnet sich dadurch aus, daß in die Leichtmetallmatrix aus der Ebene der bandartigen Profilkomponente herausragende Ausformungen eingebettet und mit ihr formschlüssig verbunden werden. Bevorzugt werden die Ausformungen der bandartigen Profilkomponente/n aus deren Ebene am Eintritt in den Matrizendurchbruch gebogen.An inventive method for producing the Composite profile is characterized in that in the Light metal matrix from the level of the band-like profile component outstanding forms embedded and with her be positively connected. The are preferred Formations of the band-like profile component / s from their Level bent at the entrance to the die opening.
Von besonderer Bedeutung ist in diesem Zusammenhang die weitergehende Maßgabe des Einführens von wenigstens zwei flächig aufeinanderliegenden getrennten bandartigen Profilkomponenten in den Matrizendurchbruch, wobei sich die bandartigen Profilkomponenten zum einen im Bereich ihrer dabei nach außen gerichteten Oberfläche mit der von der Matrix gebildeten anderen Profilkomponente innig verbinden sowie anderseits von der benachbarten bandartigen Profilkomponente an den geschützt aneinanderliegenden Bandoberflächen getrennt bleiben.In this context, the further provision of the introduction of at least two separate band-like profile components lying flat on top of each other into the die opening, the band-like Profile components on the one hand in the area of yours outward surface with that of the matrix connect other formed profile components intimately as well on the other hand from the adjacent band-like profile component on the band surfaces that are protected against each other stay separated.
Bei einem weiteren erfindungsgemäßen Verfahren zur Herstellung des Verbundprofiles werden an die bandartige Profilkomponente Zusatzelemente angeschweißt, und die aus der Ebene der bandartigen Profilkomponente herausragenden Zusatzelemente werden eingebettet sowie mit ihr formschlüssig verbunden. In a further production method according to the invention of the composite profile are attached to the band-like profile component Additional elements welded, and from the Level of the band-like profile component outstanding additional elements are embedded and form-fitting with it connected.
Insgesamt führt die beschriebene Lösung zu einem die bleibende innige Bindung der Profilkomponenten gewährleistenden Verbundprofil und damit zur vollkommenen Lösung der vom Erfinder gesehenen Aufgabe. Overall, the solution described leads to a permanent one ensuring intimate binding of the profile components Composite profile and thus the perfect solution to that of the inventor seen task.
