Description

Die vorliegende Erfindung betrifft einen Dübel zum Einsetzen in eine Leichtbauplatte gemäß dem Oberbegriff des Anspruchs 1, eine Leichtbauplatte und ein Verfahren zur Montage eines Dübels in eine Leichtbauplatte.The present invention relates to a dowel for insertion into a lightweight board according to the preamble of claim 1, a lightweight board and a method for mounting a dowel in a lightweight board.

Solche an sich aus dem Stand der Technik bekannten Dübel dienen dazu, Beschlagteile oder dergleichen an einer Leichtbauplatte festlegen zu können, wobei die Belastungen in dem Verbindungsbereich in der Regel statisch und relativ klein sind. Die Leichtbauplatte besteht dabei in der Regel aus zwei Deckplatten und einer dazwischen liegenden Mittelschicht. Zur Montage des Dübels wird in eine der beiden Deckplatten eine Bohrung eingebracht, die bis an die zweite Deckplatte heranreicht, diese aber nicht durchdringt. Anschließend wird der Dübel in diese Bohrung eingesetzt. Zur Fixierung des Dübels in der Bohrung ist beispielsweise aus der DE 10 2005 060 528 A1 bekannt, den aus einem Thermoplast bestehenden Dübel per Ultraschall in der Leichtbauplatte zu verschweißen. Zur Verschweißung der dort gezeigten Dübel ist ein hoher Energieeintrag notwendig, um ein Verschmelzen eines Teils der Dübelaußenfläche mit den Deckplatten zu ermöglichen.Such known per se from the prior art dowels serve to be able to determine fittings or the like on a lightweight panel, the stresses in the connection area are usually static and relatively small. As a rule, the lightweight board consists of two cover plates and an intermediate middle layer. To assemble the dowel, a hole is made in one of the two cover plates, which extends as far as the second cover plate but does not penetrate it. Then the dowel is inserted into this hole. For fixing the anchor in the bore is for example from the DE 10 2005 060 528 A1 known to weld the existing of a thermoplastic dowels by ultrasound in the lightweight board. To weld the dowels shown there, a high energy input is necessary to allow a fusion of a part of the dowel outer surface with the cover plates.

Aufgabe der vorliegenden Erfindung ist es, einen Dübel sowie ein Verfahren zur Montage eines Dübels bereitzustellen, mit dem sich die thermische Belastung der Bauteile weiter reduzieren lässt und mit dem eine definierte Flächenverschweißung ermöglicht ist.Object of the present invention is to provide a dowel and a method for mounting a dowel, with which the thermal load of the components can be further reduced and with a defined surface welding is possible.

Diese Aufgabe wird durch einen Dübel mit den Merkmalen des Anspruchs 1 sowie ein Verfahren zur Montage eines Dübels mit den Merkmalen des Anspruchs 11 gelöst.This object is achieved by a dowel with the features of claim 1 and a method for mounting a dowel with the features of claim 11.

Erfindungsgemäß weist das stirnseitige Ende des Dübels, das der durchbohrten Deckplatte gegenüberliegenden Deckplatte der Leichtbauplatte zugewandt ist, aufschmelzbare Energierichtungsgeber auf. Durch die Energierichtungsgeber wird die auf den Dübel übertragene Energie auf eine kleine Fläche konzentriert, wodurch ein definiertes Aufschmelzen des Dübels an bestimmten Stellen des Dübels erst möglich ist. Außerdem reduziert sich durch die Energierichtungsgeber der Energiebedarf zum Aufschmelzen der Dübelteile, so dass die Bauteile auch insgesamt weniger stark thermisch belastet werden. Zusätzlich kann durch den Einsatz dieser Energierichtungsgeber die Schweißzeit verkürzt werden, was ebenfalls zu einer Reduzierung der thermischen Belastung der Bauteile führt.According to the invention, the frontal end of the dowel, which faces the perforated cover plate opposite cover plate of the lightweight board, on fusible energy directors on. Due to the energy directors, the energy transferred to the dowel is concentrated in a small area, whereby a defined melting of the dowel at certain points of the dowel is only possible. In addition, reduced by the energy directors of the energy demand for melting the dowel parts, so that the components are less thermally stressed overall. In addition, the use of these energy directors, the welding time can be shortened, which also leads to a reduction in the thermal load of the components.

Vorteilhafte Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche.Advantageous embodiments of the invention are the subject of the dependent claims.

Gemäß einer besonderen Ausführungsvariante ist der Dübel zweiteilig als Hülse mit einem in der Hülse festlegbaren Bolzen ausgebildet, wobei die Energierichtungsgeber zumindest an der der durchbohrten Deckplatte gegenüberliegenden Deckplatte zugewandten Stirnseite der Hülse vorgesehen sind. Durch die zweiteilige Gestaltung eines Dübels ist ermöglicht, dass bei dem erfindungsgemäßen Verfahren in einem ersten Arbeitsschritt eine erste Sonotrode in die Hülse eingeführt werden kann, um eine Beaufschlagung der Hülse mit Ultraschall nur im Bereich des Hülsenbodens auszuführen und dadurch die thermische Belastung der Hülse zu reduzieren.According to a particular embodiment, the dowel is formed in two parts as a sleeve with a fixable in the sleeve bolt, the energy directors are provided at least on the cover plate opposite the pierced cover plate facing end face of the sleeve. The two-part design of a dowel makes it possible that in the method according to the invention in a first step, a first sonotrode can be inserted into the sleeve to perform an impact of the sleeve with ultrasound only in the region of the sleeve bottom and thereby reduce the thermal stress on the sleeve ,

Der in die Hülse einführbare Bolzen besteht in einer Ausführungsvariante aus einem in die Hülse einführbaren Bolzenstab und einem auf dem offenen Ende der Hülse aufsetzbaren Bolzenkopf, wobei die Grundfläche des Bolzenkopfes der Grundfläche der Hülse entspricht und der Bolzenkopf im montierten Zustand des Dübels mit der Hülse ultraschallverschweißt ist. Der Bolzenkopf ist dabei auf seiner der offenen Stirnseite der Hülse zugewandten Unterseite mit mehreren Aufschmelzstufen ausgebildet, so dass die Dicke des Bolzenkopfes radial zum Bolzenstab hin zunimmt. Dadurch wird sichergestellt, dass durch die Beaufschlagung mit Ultraschall zunächst die äußere Stufe und der Rand der Hülse aufgeschmolzen werden, ehe eine weiter innen gelegene Stufe mit der Innenfläche der Hülse in Kontakt tritt und so der bereits aufgeschmolzene Rand der Hülse nach außen gedrückt werden kann, so dass sich ein formschlüssiger Hinterschnitt und gegebenenfalls ein Verschmelzen zwischen dem Rand der Hülse und der oberen Deckschicht ergibt.The insertable into the sleeve bolt consists in a variant of an insertable into the sleeve bolt rod and an attachable on the open end of the sleeve bolt head, wherein the base of the bolt head corresponds to the base of the sleeve and the bolt head ultrasonically welded in the assembled state of the anchor with the sleeve is. The bolt head is formed on its underside facing the open end side of the sleeve with a plurality of reflow stages, so that the thickness of the bolt head increases radially toward the bolt rod. This ensures that the outer stage and the edge of the sleeve are first melted by the application of ultrasound before a step located further in the interior comes into contact with the inner surface of the sleeve and so the already melted edge of the sleeve can be pushed outwards, so that there is a positive undercut and optionally a fusion between the edge of the sleeve and the upper cover layer.

In einer weiteren Ausführungsvariante steht das offene Ende des Dübels aus der Außenfläche der mit der Bohrung versehenen Deckplatte hervor. Dadurch ist ermöglicht, dass durch Aufsetzen geeignet geformter Sonotroden ein die obere Deckschicht formschlüssig haltendes Verbindungsteil geformt wird.In a further embodiment, the open end of the plug protrudes from the outer surface of the cover plate provided with the bore. This makes it possible that by forming suitably shaped sonotrodes a form-fitting holding the upper cover layer connecting part is formed.

In der 1 ist eine Leichtbauplatte 1 gezeigt, die in an sich bekannter Weise aus einer ersten und einer zweiten Deckplatte 3, 4 sowie einer dazwischen angeordneten Mittelschicht 6 besteht. Die Mittelschicht 6 kann dabei als Waben- oder einer ähnlichen Struktur ausgeführt sein und kann sich in ihrer chemischen und/oder physikalischen Eigenschaft von den Deckplatten unterscheiden. Leichtbauplatten, die beispielsweise im Möbelbau eingesetzt werden, haben oft für Ihre Mittelschichten eine geringere Dichte als die Deckplatten 3, 4. Die beiden Deckplatten 3, 4 können beispielsweise aus Holz oder einem holzartigen Werkstoff hergestellt sein oder auch aus einem Thermoplast.In the 1 is a lightweight board 1 shown in a conventional manner from a first and a second cover plate 3 . 4 and a middle layer disposed therebetween 6 consists. The middle class 6 can be designed as a honeycomb or a similar structure and may differ in their chemical and / or physical property of the cover plates. Lightweight panels, which are used in furniture, for example, often have a lower density for their middle layers than the cover plates 3 . 4 , The two cover plates 3 . 4 may for example be made of wood or a wood-like material or of a thermoplastic.

In die obere der beiden Deckplatten 4 ist eine Bohrung 5 zur Aufnahme eines mit dem Bezugszeichen 2 bezeichneten Dübels eingebracht. Der Dübel 2 ist bevorzugt aus einem Thermoplast wie beispielsweise Polyoxymethylen (POM) oder Polyamid (PA) hergestellt.In the upper of the two cover plates 4 is a hole 5 for receiving one with the reference numeral 2 introduced dowel introduced. The dowel 2 is preferably made of a thermoplastic such as polyoxymethylene (POM) or polyamide (PA).

Die offene Stirnseite des Dübels 2 ist bevorzugt mit einem Kanal 7 versehen, der beispielsweise als Einschraubkanal ausgebildet ist und zur Aufnahme einer Befestigungsschraube (nicht gezeigt) dient.The open end of the dowel 2 is preferred with a channel 7 provided, for example, is designed as a screw-in and serves to receive a fastening screw (not shown).

Zur Festlegung des Dübels 2 in der Leichtbauplatte 1 wird der Dübel 2 mit der Leichtbauplatte 1 ultraschallverschweißt. Um eine zielgerichtete Aufschmelzung des Dübelmaterials zu erreichen, sind, wie bei dem in einer ersten Ausführungsvariante zweiteilig ausgebildeten Dübel 2, bestehend aus einer äußeren Hülse 8 und einem in die Hülse 8 einführbaren Bolzen 9, an einem stirnseitigen, dem der durchbohrten Deckplatte 4 gegenüberliegenden Deckplatte 3 zugewandten Ende des Dübels 2 aufschmelzbare Energierichtungsgeber 12 angeformt. Der Bolzen 9 besteht dabei aus einem in die Hülse 8 einführbaren Bolzenstab 10 und einem auf dem offenen Ende der Hülse 8 aufsetzbaren Bolzenkopf 11.To fix the dowel 2 in the lightweight board 1 becomes the dowel 2 with the lightweight board 1 ultrasonically welded. In order to achieve a targeted melting of the dowel material, as in the case of the two-part dowel designed in a first embodiment variant 2 consisting of an outer sleeve 8th and one in the sleeve 8th insertable bolt 9 , at one end, that of the pierced cover plate 4 opposite cover plate 3 facing the end of the dowel 2 fusible energy directors 12 formed. The bolt 9 consists of one in the sleeve 8th insertable stud rod 10 and one on the open end of the sleeve 8th attachable bolt head 11 ,

Wird die Hülse 8 nach dem Einführen in die Bohrung 5 der oberen Deckplatte 4 mit Ultraschall beaufschlagt, werden die Energierichtungsgeber 12 aufgeschmolzen und sorgen so für eine zuverlässige Verbindung mit der unteren Deckplatte 3.Will the sleeve 8th after insertion into the hole 5 the upper cover plate 4 When exposed to ultrasound, the energy directors become 12 melted and thus ensure a reliable connection with the lower cover plate 3 ,

Bei der in 2 gezeigten Ausführungsvariante wird zur Beaufschlagung der Hülse mit Ultraschall eine Sonotrode 13 auf den Bolzenkopf 11 aufgelegt. Der über die Sonotrode 13 auf den Bolzen übertragene Ultraschall bewirkt dabei zunächst ein Aufschmelzen eines Kontaktbereiches zwischen Hülse 8 und Bolzen 9 im Bereich des offenen Endes der Hülse 8.At the in 2 the embodiment shown is to apply a sonotrode to the sleeve with ultrasound 13 on the bolt head 11 hung up. The over the sonotrode 13 Ultrasound transmitted to the pin initially causes a melting of a contact area between the sleeve 8th and bolts 9 in the region of the open end of the sleeve 8th ,

Wie in den 3 und 4 zu erkennen ist, ist die der offenen Stirnseite der Hülse 8 zugewandte Unterseite des Bolzenkopfes 11 mit mehreren Aufschmelzstufen 14, 15 ausgebildet. Gleichzeitig ist die Innenkante des offenen Endes der Hülse 8 mit einer Fase versehen. Führt man den Bolzen 9 in die Hülse 8 ein, so liegt der Bolzen 9 mit der radial außen liegenden Aufschmelzstufe 14 auf dem angefasten Ende der Hülse 8 auf, um sicherzustellen, dass bei Beaufschlagung des Dübels 2 mit Ultraschall zunächst dieser Kontaktbereich aufgeschmolzen wird, ehe die angefaste Fläche 16 der Hülse 8 mit der weiter innen liegenden Stufe 15 des Bolzenkopfes 11 in Kontakt kommt und ebenfalls aufschmilzt. Während des Aufschmelzvorgangs wird der Bolzen 9 weiter in die Hülse 8 hinein gedrückt, so dass das aufgeschmolzene Material im Wandbereich des offenen Endes der Hülse 8 nach außen gedrückt wird, so dass sich ein formschlüssiger Hinterschnitt 22 am offenen Ende der Hülse 8 ausbildet. Dieser Hinterschnitt 22 ragt radial von der Bohrung 5 in der oberen Deckplatte 4 über den Rand der Bohrung 5 auf der der unteren Deckplatte 3 zugewandten Seite der oberen Deckplatte 4 hinaus und verhindert damit eine Bewegung des Dübels 2 aus der Bohrung 5 heraus. Die Endlage und Endgestaltung des Dübels 2 ist in 7 gezeigt. Des Weiteren ist in 7 zu erkennen, dass sich im Kontaktbereich zwischen Hülse 8 und Bolzen 9 eine Quetschnaht 21 gebildet hat, mit der der Bolzen 9 sicher an der Hülse 8 verschweißt ist. Sofern zwischen der Mantelfläche des Bolzenkopfes 11 und der oberen Deckplatte 4 nach dem Einsetzen der Hülse 8 und des Bolzens 9 noch ein gewisses Spiel vorhanden war, so ist dieses zumindest teilweise ebenfalls durch die Quetschnaht 21 ausgefüllt.As in the 3 and 4 it can be seen that is the open end of the sleeve 8th facing bottom of the bolt head 11 with several melting stages 14 . 15 educated. At the same time, the inner edge of the open end of the sleeve 8th provided with a chamfer. If you lead the bolt 9 in the sleeve 8th a, so is the bolt 9 with the radially outer reflow stage 14 on the chamfered end of the sleeve 8th on to ensure that when loading the dowel 2 with ultrasound, this contact area is first melted before the chamfered surface 16 the sleeve 8th with the further inside stage 15 of the bolt head 11 comes in contact and also melts. During the melting process, the bolt becomes 9 further into the sleeve 8th pressed in, so that the molten material in the wall portion of the open end of the sleeve 8th is pressed outwards, so that a positive undercut 22 at the open end of the sleeve 8th formed. This undercut 22 protrudes radially from the hole 5 in the upper cover plate 4 over the edge of the hole 5 on the lower cover plate 3 facing side of the upper cover plate 4 and thus prevents movement of the dowel 2 out of the hole 5 out. The final position and final design of the dowel 2 is in 7 shown. Furthermore, in 7 to recognize that in the contact area between sleeve 8th and bolts 9 a pinch seam 21 has formed, with which the bolt 9 safely on the sleeve 8th is welded. If between the lateral surface of the bolt head 11 and the upper cover plate 4 after inserting the sleeve 8th and of the bolt 9 there was still a certain amount of play, this is at least partly due to the squeezing seam 21 filled.

In einer bevorzugten Ausgestaltung des Bolzens 9 ist, wie in 5 gezeigt ist, die dem Hülsenboden zugewandte Stirnseite des Bolzens 9 ebenfalls mit Energierichtungsgebern 18 versehen, um den Bolzen 9 in der Hülse 8 auch in diesem Bereich zu fixieren und die Festigkeit der Verbindung zwischen Bolzen und Hülse weiter zu erhöhen.In a preferred embodiment of the bolt 9 is how in 5 is shown, the sleeve bottom facing the end face of the bolt 9 also with energy directors 18 provided to the bolt 9 in the sleeve 8th also in this area to fix and to increase the strength of the connection between the bolt and sleeve on.

Die Montage des Dübels 2 in der Leichtbauplatte 1 kann in einer bevorzugten Ausführungsvariante durch Einsetzen des Dübels 2 in die Bohrung 5 in die Deckplatte 4 und anschließender Beaufschlagung des Dübels 2 mit Ultraschall durch die Sonotrode 13 erfolgen, wie es in 2 dargestellt ist. Bei der Beaufschlagung des Dübels 2 mit Ultraschall wird, wie oben beschrieben, der Dübel 2 mit der der durchbohrten Deckplatte 4 gegenüberliegenden Deckplatte 3 durch Aufschmelzen der am stirnseitigen Ende des Dübels 2 vorhandenen Energierichtungsgeber 12 verschweißt. In einer alternativen Montagevariante gemäß 6 wird zunächst die Hülse 8 in die Bohrung 5 in der Deckplatte 4 eingesetzt und anschließend eine Sonotrode 19 in die Hülse 8 eingeführt, so dass die Wirkfläche der Sonotrode 19 den Hülsenboden der Hülse 8 berührt und so eine Ultraschallbeaufschlagung der Hülse 8 in unmittelbarer Nähe der Energierichtungsgeber 12 erfolgt.The assembly of the dowel 2 in the lightweight board 1 can in a preferred embodiment by inserting the anchor 2 into the hole 5 in the cover plate 4 and then applying the anchor 2 with ultrasound through the sonotrode 13 done as it is in 2 is shown. When loading the dowel 2 with ultrasound, as described above, the dowel 2 with the pierced cover plate 4 opposite cover plate 3 by melting the at the front end of the dowel 2 existing energy directors 12 welded. In an alternative installation variant according to 6 First, the sleeve 8th into the hole 5 in the cover plate 4 and then a sonotrode 19 in the sleeve 8th introduced so that the effective area of the sonotrode 19 the sleeve bottom of the sleeve 8th touched and so a Ultraschallbeaufschlagung the sleeve 8th in the immediate vicinity of the energy directors 12 he follows.
