Abstract
Description
Die Erfindung betrifft einen Schaumformkörper aus einem ela stisch nachgiebigen Kunststoffmaterial gemäß dem Oberbegriff des Patentanspruches 1.The invention relates to a foam molded body from an ela flexible plastic material according to the preamble of claim 1.
Es wird heute allgemein angestrebt, die in den Innenraum eines Kraftfahrzeuges eindringenden Geräusche zu minimieren. Dies erfordert eine gezielte Schalldämmung an der Blechstruktur der Kraftfahrzeuge, vor allem an den tragenden Säulen der Karosse rie, z. B. der Vorderwand-, der Mittel- und der Hecksäule, die als Hohlprofile ausgeführt sind und über die eine Übertragung des Luftschalls vom Fahrwerk des Kraftfahrzeuges in den Fahr zeuginnenraum erfolgt.It is generally sought today that in the interior of a To minimize motor vehicle intrusive noise. This requires targeted sound insulation on the sheet metal structure of the Motor vehicles, especially on the supporting pillars of the body rie, e.g. B. the front wall, the middle and the rear pillar, the are designed as hollow profiles and via which a transmission of airborne noise from the chassis of the motor vehicle in the driving witness interior is done.
Zur Abschottung dieser Säulen und auch anderer Hohlräume bei Kraftfahrzeugen bietet sich an, diese Hohlräume mit Schaum stoff-Körpern auszufüllen. Die beste Möglichkeit für das Ein bringen der Schaumstoff-Körper in die Hohlräume wäre beim Auf bau von Kraftfahrzeugteilen in der Rohbaufertigung gegeben. Ein solches Abdichten der Hohlräume in diesem Fertigungsstadium ist aber deswegen nicht möglich, weil bei der anschließenden Elektrotauchlackierung der Bauteile eine Beschichtung der mit dem Schaumstoff-Körper abgedeckten Blechflächen nicht erfolgt. Damit entstünde einmal die Gefahr von Korrosion bei den Blech flächen und außerdem wäre ein Abfließen der Badflüssigkeit bei der Karosserievorbehandlung und der Tauchlackierung nicht mehr möglich.To seal off these pillars and other cavities Motor vehicles lend themselves to these cavities with foam fill in fabric bodies. The best way to get one would bring the foam body into the cavities when opening Construction of automotive parts in the body shop. A such sealing of the cavities is at this stage of manufacture but not possible because the subsequent one Electrocoating the components with a coating of the sheet metal surfaces covered by the foam body are not made. This would create the risk of corrosion in the sheet metal surfaces and also would drain the bath liquid body pre-treatment and dip painting no longer possible.
Denkbar wäre es auch, die Abschottung der entsprechenden Bau teile mit dem Schaumstoff-Körper nach der Lackierung, d. h. zu Beginn der Fahrzeugmontage vorzunehmen. In der Regel sind aber dann die Hohlräume nicht mehr zugänglich und nach dem heutigen Stand der Technik wäre ein Ausschäumen der Hohlräume nur mit einem 2-Komponenten-Schaumsystem durchzuführen. Dies würde je doch einen großen maschinellen Aufwand bedeuten und der Einsatz einer 2-Komponenten-Technik bei der Fahrzeugmontage ist pro blematisch.It would also be conceivable to foreclosure the corresponding construction share with the foam body after painting, d. H. to Start of vehicle assembly. As a rule, however then the cavities are no longer accessible and according to today's State of the art would only include foaming the cavities a 2-component foam system. This would ever but mean a great deal of mechanical effort and use a 2-component technology for vehicle assembly is pro blemish.
Aus der DE-OS 38 26 012 ist nun bereits ein Verfahren und ein Schaumstoffkörper zur Abschottung von Hohlkörpern bekannt, wo bei in den Hohlraum des Hohlkörpers ein aus einem offenzelligen Schaumstoff bestehender Körper eingeführt wird, der vollständig mit einer gasundurchlässigen Haut überzogen ist. Diese Haut besitzt wenigstens eine Öffnung, an die beim Einführen des Schaumstoff-Körpers ein Vakuum zur Komprimierung des Schaum stoff-Körpers angelegt wird. Nach dem Einführen in den Hohlraum läßt man den kontrahierten Schaumstoff-Körper durch Beseitigung des Vakuums expandieren, so daß er dann den Hohlraum ausfüllt.DE-OS 38 26 012 is already a method and a Foam body for sealing hollow bodies known where when in the cavity of the hollow body one from an open cell Foam existing body is introduced completely is covered with a gas-impermeable skin. That skin has at least one opening at which the Foam body a vacuum to compress the foam fabric body is created. After insertion into the cavity let the contracted foam body by removal expand the vacuum so that it then fills the cavity.
In dieser Schrift ist zwar nichts darüber ausgesagt, zu welchem Zeitpunkt der Schaumstoff-Körper in den Hohlraum eingeführt werden soll und das Vakuum aufgehoben werden soll, jedoch ist üblicherweise das Einführen nur in der Rohbauphase der Karos serie möglich. Geschieht das Expandieren des Schaumformkörpers vor einer Elektrotauchlackierung der Bauteile, würde eine op timale Beschichtung der Blechflächen nicht erfolgen können, d. h. bei den Blechflächen kann eine Korrosion eintreten. Eine Expansion des Schaumstoff-Körpers nach der Lackierung würde ein dauerndes künstliches Aufrechterhalten des Vakuums bedeuten; das ist aber kaum möglich und wäre auf jeden Fall sehr umständ lich.In this document nothing is said about which one Time the foam body is inserted into the cavity should be and the vacuum should be released, however Usually the insertion only in the body-in-white phase of the checks series possible. Happens the expansion of the molded foam body before electro-painting the components, an op timely coating of the sheet metal surfaces cannot take place, d. H. Corrosion can occur on the sheet metal surfaces. A Expansion of the foam body after painting would take place means permanent artificial maintenance of the vacuum; but that is hardly possible and would be very difficult in any case Lich.
Aus der DE-OS 35 06 004 ist ferner ein aus einem offenzelligen Schaumstoff bestehender Füllkörper bekannt, wobei der Füllkör per volumenkomprimiert und allseitig von einer Folie umhüllt ist. Dabei ist die evakuierte, umhüllende Folie des um ein Vielfaches des Ausgangsvolumens komprimierten Schaumstoffes gegenüber dem komprimierten Volumen um so viel größer als sich der Schaumstoff nach Wegfall des Vakuums zurückstellt. Das Va kuum wird bei dem komprimierten, umhüllten Füllkörper durch Perforation der Hüllfolie aufgehoben.From DE-OS 35 06 004 is also one from an open cell Foam existing packing known, the packing compressed by volume and covered on all sides by a film is. The evacuated, enveloping film is a Multiples of the initial volume of compressed foam compared to the compressed volume so much larger than itself the foam resets after the vacuum is removed. The Va Vacuum is applied to the compressed, enveloped packing Perforation of the wrapping film removed.
Die Aufgabe der Erfindung besteht nun darin einen Schaumstoff körper aus einem elastisch nachgiebigen Kunststoffmaterial zu schaffen, mit dem es möglich ist, ohne eine pneumatische Ex pansion oder eine Perforation der umhüllenden Folie nach dem Einbringen des Schaumstoffkörpers in einen Karosseriehohlraum, diesen optimal abzuschotten.The object of the invention is now a foam body made of an elastically resilient plastic material create with which it is possible without a pneumatic Ex pansion or a perforation of the enveloping film after the Inserting the foam body into a body cavity, to isolate it optimally.
Die gestellte Aufgabe wird mit den Merkmalen des Patentan spruches 1 gelöst.The task is with the features of the patent Proverb 1 solved.
Ein Verfahren zum Abschotten von Karosseriehohlräumen zwecks Schalldämmung unter Verwendung eines solchen Schaumformkörpers wird in dem Patentanspruch 5 angegeben.A method of sealing body cavities for the purpose Sound insulation using such a molded foam body is specified in claim 5.
In der Praxis wird als Kunststoffmaterial Polyurethan, insbe sondere ein Weich-Polyurethan, eingesetzt. Bei der Bandage kann es sich um eine Folie handeln, die auch lochartig perforiert sein kann oder Schlitze aufweist. Auch Netze aus Kunststoffmaterial können zur Bandagierung des Schaumformkör pers Verwendung finden.In practice, the plastic material is polyurethane, especially special a soft polyurethane used. The bandage can it is a film that also perforates like a hole can be or has slots. Even networks Plastic material can be used for bandaging the foam molding find personal use.
Als Folienmaterial hat sich insbesondere Polyethylen als ge eignet erwiesen.In particular, polyethylene has proven to be a film material proven.
Bei der Verfahrensdurchführung erfolgt die Einführung des Schaumstoffkörpers in den Hohlraum in einem Fertigungsstadium, in dem der Hohlraum leicht zugänglich ist und der in den Hohl raum angeordnete Schaumstoffkörper bei der anschließenden Lackierung die Beschichtung der Blechflächen nicht behindert. When the procedure is carried out, the Foam body in the cavity at a manufacturing stage, in which the cavity is easily accessible and in the cavity Foam body arranged in space during the subsequent Painting does not hinder the coating of the sheet metal surfaces.
Anschließend soll ohne einen Eingriff von außen der Schaum stoff-Körper den Hohlraum des Kraftfahrzeugteiles vollständig abschotten.Then the foam should be done without external intervention fabric body completely the cavity of the motor vehicle part isolate.
In der Praxis wird das Verfahren so durchgeführt, daß ein in seinen Ausmaßen den abzuschottenden Hohlraum des Bauteiles entsprechender Schaumstoff-Zuschnitt komprimiert und in eine Kunststoff-Umhüllung eingeschweißt wird. Das Komprimieren des Schaumstoff-Zuschnittes erfolgt durch rein mechanisches Zusam menpressen. Anschließend wird der komprimierte und bandagierte Schaumstoff-Zuschnitt in den abzuschottenden Hohlraum einge führt und darin so befestigt, daß er die Wandungen des Hohl raumes nicht abdeckt. Damit wird gewährleistet, daß beim nach folgenden Lackierungsvorgang des Bauteiles die Wände des Hohl raumes ausreichend beschichtet werden und die Badflüssigkeit ungehindert durch den Hohlraum abfließen kann.In practice, the process is carried out so that an in its dimensions the partition of the component to be sealed off appropriate foam cut compressed and into a Plastic wrapping is welded. Compressing the Foam cutting is done by a purely mechanical combination men presses. Then the compressed and bandaged Foam cut into the cavity to be sealed off leads and fastened in it so that he the walls of the hollow does not cover the room. This ensures that the after following painting process of the component the walls of the hollow room and the bath liquid can flow freely through the cavity.
Durch die erhöhte Temperatur des Trockenofens nach der Lackierung wird die den Schaumstoff-Zuschnitt bandagierende Kunststoff-Umhüllung zum Schmelzen gebracht. Der Schaumstoff- Zuschnitt expandiert und füllt den Hohlraum aus. Als Material für die Kunststoff-Umhüllung wählt man in bevorzugter Weise ein Material aus, das nach dem Schmelzen eine Klebeverbindung mit dem Blech des Hohlraumes eingeht, d. h. wie ein Schmelzklebstoff wirkt.Due to the increased temperature of the drying oven after Painting is the bandaging of the foam blank Plastic coating melted. The foam Blank expands and fills the cavity. As a material for the plastic covering one chooses in a preferred manner Material made with an adhesive connection after melting the sheet metal of the cavity, d. H. like a hot melt adhesive works.
Um ein sicheres Ausfüllen des Hohlraumes unbedingt zu gewähr leisten, wird man den Zuschnitt in seiner Form mit Übermaß ausführen. Auf diese Art wird ein sicheres Abschotten des Hohlraumes mit einem unter Spannung stehenden Zuschnitt er reicht.To guarantee a safe filling of the cavity afford, you will oversize the shape To run. In this way, a safe isolation of the Cavity with a live blank he enough.
Der Erfindungsgegenstand wird anhand der Fig. 1 und 2 noch näher erläutert: The subject matter of the invention is explained in more detail with reference to FIGS. 1 and 2:
Die Fig. 1 zeigt im Schnitt den Karosseriehohlraum mit den eingelegten und komprimierten Schaumformkörper. In dieser Figur wird der Hohlraum durch das Außenblech 1 und das Innenblech 2 des Karosserieteiles gebildet. Auf der Innenseite des Innen bleches 2 sind Haken 2 vorhanden, in die der komprimierte Schaumformkörper 4, umhüllt mit einer Folie 5, eingehängt wird. Fig. 1 shows in section the body cavity with the inserted and compressed foam molded body. In this figure, the cavity is formed by the outer panel 1 and the inner panel 2 of the body part. On the inside of the inner sheet 2 hooks 2 are present, in which the compressed foam molded body 4 , covered with a film 5 , is suspended.
Die Fig. 2 zeigt einen Schnitt durch den Karosseriehohlraum nach Aufhebung der Kompression des Schaumformkörpers. Der Schaumformkörper 4 füllt den Hohlraum zwischen den beiden Blechen 1 und 2 völlig aus. Zwischen den Innenwandungen der beiden Bleche 1 und 2 und dem Schaumformkörper ist aus der ge schmolzenen Folie eine Klebeschicht 6 gebildet worden. Fig. 2 shows a section through the body cavity after the lifting of the compression of the foam molded body. The foam molding 4 completely fills the cavity between the two sheets 1 and 2 . Between the inner walls of the two sheets 1 and 2 and the molded foam body, an adhesive layer 6 has been formed from the molten sheet.
Der Vorteil des erfindungsgemäßen Schaumformkörpers besteht insbesondere darin, daß es mit ihm möglich ist, nachdem der bandagierte und komprimierte Schaumformkörper in den Karosse riehohlraum eingelegt worden ist, ohne eine pneumatische Ex pansion bei dem Schaumformkörper, ein optimales Abschotten des Hohlraumes zu erzielen. Der Schaumformkörper wird in die Hohl räume von Bauteilen in einem Fertigungsstadium des Kraftfahr zeuges eingebracht, wo die Hohlräume noch leicht zugänglich sind. Das Aufheben der Kompression des Schaumstoffkörpers er folgt allein durch das Aufheizen des Karosseriehohlraumes mit dem Schaumstoffkörper. Es ist lediglich darauf zu achten, daß die Aufheiztemperatur bis wenigstens an den Schmelzpunkt des Bandagematerials erfolgt.The advantage of the molded foam body according to the invention is especially in that it is possible with him after the bandaged and compressed foam molded body in the body cavity has been inserted without a pneumatic Ex expansion with the molded foam body, an optimal partitioning of the To achieve cavity. The foam molding is in the hollow Clear components in a manufacturing stage of the motor vehicle Stuff introduced where the cavities are still easily accessible are. Removing compression of the foam body follows only by heating the body cavity the foam body. It is only important to ensure that the heating temperature up to at least the melting point of the Bandage material takes place.
