Description
Die Erfindung betrifft ein Verfahren gemäß dem Oberbegriff des Patentanspruchs 1.
Bei der Herstellung von Metall-Kunststoff-Verbundelementen, wie sie z. B. aus der EP 0 732 234 A2
bekannt sind, durch Aufbringen von Kunststofflagen (Laminieren) auf der Ober- und
der Unterseite winkelförmig profilierter Metallkerne (Metallstäbe) werden Thermoplaste und
Duroplaste als Verbindungsschichten sowohl der Kunststoff-Gewebelagen untereinander, als
auch zur Verbindung der Gewebepakete mit dem Metallkern benutzt.
Neben dem Vakuum-Sack-Verfahren wird auch die Pressentechnik für die Fertigung solcher
Werkstücke eingesetzt (beide Verfahren prinzipiell beschrieben z. B. in Fleming, M.; Ziegmann,
G.; Roth, S.; Faserverbundweisen, Springer-Verlag Berlin Heidelberg New York 1996).
Beiden Verfahren ist gemeinsam, dass sie zum Fügen winkelbehafteter Elemente, Formele
mente als Ober- und Unterformen zur Einstellung der gewünschten Teilegeometrie benutzen.
Ferner wenden beide Verfahren als gemeinsames Kriterium die Methode der mittelbaren Ein
bringung der zum Prozessablauf erforderlichen thermischen Energie an. Zudem muss nach
Reaktionsabschluss die Wärme des gesamten Aufbaus Werkstück/Formelemente im Rahmen
des Abkühlzyklus nach außen abgeführt werden.
Beim Vakuum-Sack-Verfahren werden die lose zusammengefügten Einzellagen des späteren
Verbundkörpers in formenden Vorrichtungen fixiert und durch Evakuieren des sie vollständig
überdeckenden Vakuumsacks über textile Hilfselemente mit einer Druckkraft beaufschlagt.
Nach dieser vorbereiteten Phase wird das Gesamtarrangement entweder durch Heizplatten
oder durch Einbringen in einen geschlossenen Ofenraum erwärmt.
An den Erwärmryklus mit einer maximalen Prozesstemperatur von ca. 200°C schließt sich,
insbesondere bei Thermoplasten, unmittelbar ein Abkühlzyklus unter weiterhin wirksamem
Druck an, welcher der Stabilisierung des Formlings dient.
Bei der Teileherstellung durch die Pressentechnik wird der notwendige Druck durch eine Pres
se (hydraulisch, pneumatisch, mechanisch) erzeugt. Die Einzellagen des späteren Werkstücks
werden im Falle nicht ebener Gestalt in Pressformen (Ober- und Unterform) fixiert.
Die Form selber wird entweder mittels Elektroheizplatten oder durch ein wärmeübertragendes
Fluid beheizt. Kühleinrichtungen dienen zur Realisierung des Abkühlzyklus.
Aufgrund der physikalischen Gegebenheiten der Wärmeleitung und des Wärmeübergangs
sind die beiden zitierten Verfahren durch relativ lange Erwärm- und Abkühlzyklen gekenn
zeichnet. Das zieht relativ lange Prozesszeiten mit relativ geringem Werkstückdurchsatz pro
Zeiteinheit und Fertigungsaggregat nach sich.
Von daher liegt der Erfindung die Aufgabe zugrunde, ein Verfahren der eingangs genannten
Art zu schaffen, mit dem auf einfache Weise eine Verbesserung der Wirtschaftlichkeit des La
miniervorgangs bei der Herstellung winkelförmig profilierter Metall-Kunststoff-Verbundele
menten erreicht werden kann, wobei die Neigung des Verschwimmens zwischen den drei
Komponenten Oberschale, Unterschale und Metallkern deutlich reduziert und die Maßgenau
igkeit und Fertigungssicherheit erhöht werden.
Nach der Erfindung wird die Aufgabe durch die im Patentanspruch angegebenen Merkmale
gelöst.
Durch die unmittelbare Erwärmung des Metallkerns wird dessen thermische Energie zum Ver
kleben desselben mit den in der Regel elektrisch nicht leitenden und zweckmäßigerweise vor
gefertigten Ober- und Unterschalen (Lagenpakete aus Kunststoff, miteinander verklebt) be
nutzt.
Die thermische Energie des Metallkerns schmilzt die thermoplastische oder duroplastische
Klebmasse, in der Regel als Folie ausgebildet, die sich zwischen Metallkern und Ober- bzw.
Unterschale befindet, auf. Die Klebefolie kann hierbei bereits Bestandteil der vorgefertigten
Ober- und Unterschale sein und sowohl mit dem eigentlichen Matrixmaterial identisch als
auch unterschiedlich zu diesem sein. Durch einen äußeren Druckaufbau, zweckmäßigerweise
durch eine Presse, werden die drei Teilelemente des Werkstücks, Oberschale, Unterschale
und Metallkern, form- und kraftschlüssig miteinander verbunden.
Neben der Erwärmphase wird durch das erfindungsgemäße Verfahren auch die anschließen
de Abkühlphase des Prozesses gegenüber dem Stand der Technik deutlich reduziert. Wäh
rend bei dem bekannten zitierten Verfahren entsprechend dem Stand der Technik die thermi
sche Energie des Gesamtsystems Formen-Gesamtwerkstück abgeführt werden muss, ist bei
dem erfindungsgemäßen Verfahren lediglich die Wärmeenergie des zuvor auf Prozesstempe
ratur erwärmten Metallkerns abzuführen. Da letztere aus Massegründen um Größenordnun
gen geringer ist als im ersten Fall, ergeben sich dementsprechend auch deutlich verkürzte
Zyklusdauern.
Aus der DE 31 08 221 A1 ist zwar eine Vorrichtung und ein Verfahren zur Herstellung von ver
klebten Kunststoff- und Metallteilen unter Einsatz einer Induktionsspule bekannt, wel
che/welches aber keinen Hinweis auf das spezielle erfindungsgemäße Verfahren geben kann,
da hier nur ebene Teile verwendet werden.
Anhand der schematischen Zeichnung wird das erfindungsgemäße Verfahren nachfolgend
näher erläutert.
Bei der erfindungsgemäßen Verfahrensweise wird ein zu laminierendes Werkstück 2, beste
hend aus Oberschale 2.1, Metallkern 2.2 und Unterschale 2.3 in ein Formelement 1, das aus
Oberform 1.2 und Unterform 1.3 besteht, eingelegt. Die Elemente 2.4 stellen den folienartig
ausgebildeten Klebstoff dar. Der Metallkern 2.2 ist als winkelförmiger Stab ausgebildet. Ein
Induktor 8 bzw. 9 ist so ausgebildet, dass er vollständig in Oberform 1.2 und Unterform 1.3
integriert die erforderliche Druckkraft 7 des Prozesses zu übertragen gestattet. Ein HF-
Generator 10 im Stromkreis 6 wird mittels des Reglers 6.1 bezüglich seiner abgegebenen
Leistung so geregelt, dass im Metallkern 2.2 der gewünschte Zeit-Temperatur-Verlauf ent
steht. Die aktuelle Temperatur des Metallkerns 2.2 wird durch den Thermofühler 6.2 gemes
sen und die entsprechende elektrische Größe dem Regler 6.1 zugeführt.
