Abstract
Description
Die Erfindung betrifft eine Einrichtung zum Füllen von Hohlkörpern. Hohlkörper, wie Rohre, Stangen oder Hohlträger, welche beispielsweise aus Metall bestehen und extrudiert, tiefgezogen, gebaut und/oder nach dem Innenhochdruckverfahren hergestellt werden, sind für verschiedenste Anwendungsgebiete bekannt. Unter anderem werden derartige Hohlkörper im Kraftfahrzeugbau als Strukturbauteil eingesetzt, da sie eine leichte aber dennoch belastbare Konstruktion ermöglichen.The The invention relates to a device for filling hollow bodies. Hollow body, like Pipes, rods or hollow beams, which consist for example of metal and extruded, deep-drawn, built and / or produced by the hydroforming process, are for various application areas known. Among other things, such hollow body in Motor vehicle construction used as a structural component, since they have a light but still allow a durable construction.
Beispielsweise um die Festigkeit von Hohlkörpern noch weiter zu erhöhen, um Korrosion vorzubeugen, besondere Energieabsorptionseigenschaften zu erreichen oder insbesondere um die Schalleigenschaften zu verbessern, ist es bekannt, eingangs genannte Hohlkörper zu füllen.For example for the strength of hollow bodies to increase even further to prevent corrosion, special energy absorption properties to achieve or in particular to improve the sound properties, It is known to fill the aforementioned hollow body.

Die WO 99/48746 A1 beschreibt ein Hohlprofil mit Innenversteifung. Die Innenversteifung besteht aus einem festen Kernmaterial, welches mit einem aktivierbaren Material beschichtet ist. Die Innenversteifung wird im Hohlprofil positioniert, nachfolgend wird die aktivierbare Beschichtung durch Zufuhr erhöhter Temperatur zur Reaktion gebracht, wobei das aktivierbare Material aufschäumt und das Hohlprofil gefüllt wird. Der Füllkern muss dabei exakt an einer vorgegebenen Stelle Positioniert werden, falls das Hohlprofil Teil einer komplexeren Struktur ist, kann eine nachträgliche Füllung des Hohlprofils nicht mehr erfolgen.The WO 99/48746 A1 describes a hollow profile with internal stiffening. The Internal stiffening consists of a solid core material, which coated with an activatable material. The inner stiffening is positioned in the hollow profile, subsequently the activatable Coating by feeding increased Temperature reacted, wherein the activatable material foams and filled the hollow profile becomes. The filler core must be positioned exactly at a given position, if the hollow profile is part of a more complex structure, a subsequent filling the hollow profile no longer done.
Aufgabe der Erfindung ist es, eine Einrichtung zum Füllen von Hohlkörpern bereitzustellen, welche bei geringem Verfahrens-, Material- und Reinigungsaufwand auf einfache Weise die Füllung von Hohlprofilen ermöglicht. Dabei soll auch eine Füllung bereits in einer komplexeren Struktur verbauter Hohlkörper ermöglich werden.task The invention is to provide a device for filling hollow bodies, which with low process, material and cleaning costs to simple Way the stuffing of hollow profiles allows. It should also be a filling already In a more complex structure built-hollow body can be made possible.
Die Lösung der Aufgabe erfolgt mit einer Einrichtung mit den Merkmalen des Anspruchs 1, wobei gemäß der zugrundeliegenden Idee die Einrichtung einen formstabilen ersten Bereich und einen expandierbaren zweiten Bereich aufweist.The solution The task takes place with a device with the characteristics of Claim 1, wherein according to the underlying Idea the establishment of a dimensionally stable first area and one having expandable second region.
Besonders zu bevorzugende Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche.Especially preferred embodiments of the invention are the subject of Dependent claims.
Besonders bevorzugt ist es, wenn zum Füllen eines Hohlkörpers der zweite Bereich durch eine Öffnung des Hohlkörpers in dessen Innenraum einführbar ist und der erste Bereich als Verschlusseinrichtung ausgebildet und zum Verschließen der Öffnung des Hohlkörpers geeignet ist.Especially it is preferred when to fill a hollow body the second area through an opening of the hollow body in the interior of which can be inserted is and the first area formed as a closure device and for closing the opening of the hollow body suitable is.
Zweckmäßigerweise ist der erste Bereich zur Fixierung in der Öffnung des Hohlkörpers form- oder kraftschlüssig festlegbar, sodass die Öffnung auch beim nachfolgenden Füllen des Hohlkörpers und am fertigen Bauteil fest verschlossen ist.Conveniently, is the first area for fixing in the opening of the hollow body form- or non-positively fixable, so that the opening also during the subsequent filling of the hollow body and is firmly closed on the finished component.
Gemäß einer vorteilhaften Ausgestaltung der Erfindung ist der zweite Bereich zur Füllung des Innenraums des Hohlkörpers thermisch oder reaktiv expandierbar.According to one advantageous embodiment of the invention is the second area to the filling the interior of the hollow body thermally or reactively expandable.
Als sehr zweckmäßig wird es angesehen, wenn der zweite Bereich zum Einführen durch eine Öffnung des Hohlkörpers in dessen Innenraum komprimierbar ist. Dadurch kann der Füllstoff leicht in den Hohlkörper eingebracht werden.When very useful it is viewed when the second area for insertion through an opening of the hollow body in the interior of which is compressible. This allows the filler easy in the hollow body be introduced.
Alternativ umfasst der zweite Bereich gemäß einer ebenfalls als sehr zweckmäßig angesehenen Ausgestaltung getrennte Komponenten eines Füllstoffs, wobei beim Einführen in den Hohlkörper die Trennung der Füllstoffkomponenten aufhebbar ist.alternative the second area comprises according to a also regarded as very useful embodiment separate components of a filler, during insertion in the hollow body the separation of the filler components can be canceled.
