Abstract
Spannrahmen zum Halten von dreidimensional zu verformenden Matten, insbesondere glasfaserverstärkten Matten, an Presswerkzeugen, bestehend aus seitlich neben dem Werkzeug angeordneten Leisten, wobei jeweils eine Leiste (4, 5) dem Ober- (2) und Unterwerkzeug (3) zugeordnet ist, die mit einer Hubvorrichtung (10, 11) zusammenwirken dadurch gekennzeichnet, dass jede Leiste (4, 5) aus einem elastischen Material besteht, wobei korrespondierende Leisten (4, 5) mit gegenpolig angeordneten Magneten (13, 14) ausgerüstet sind.Clamping frame for holding three-dimensionally deforming mats, in particular glass fiber reinforced mats, on pressing tools, consisting of laterally arranged next to the tool bars, each one bar (4, 5) is associated with the upper (2) and lower tool (3) with a lifting device (10, 11) cooperate, characterized in that each strip (4, 5) consists of an elastic material, wherein corresponding strips (4, 5) with opposite polarity arranged magnets (13, 14) are equipped.
Description
Die Erfindung bezieht sich auf einen Spannrahmen der im Oberbegriff des ersten Anspruchs angegebenen Art.The invention relates to a tenter of the type specified in the preamble of the first claim.
Die
Die
Aus der
Nachteilig bei dieser Anordnung ist es, dass komplexere Konturen nicht faltenfrei drapiert werden können und dass das Nachfließen des Materials beim Umformen über Federn gesteuert wird, die jedoch einen zu geringen linearen Kraftbereich aufweisen. Damit kann eine Schädigung der Fasern entstehen, so dass die mechanischen Eigenschaften nicht mehr nach dem Umformen erreicht werden.A disadvantage of this arrangement is that more complex contours can not be draped wrinkle-free and that the Nachfießen the material is controlled during forming by springs, but which have too low a linear force range. This can cause damage to the fibers, so that the mechanical properties are no longer achieved after forming.
Aufgabe der vorliegenden Erfindung ist es, hier Abhilfe zu schaffen und einen Spannrahmen vorzuschlagen, mit dem dreidimensionale Umformungen von Matten faltenfrei und kontrolliert möglich sind.Object of the present invention is to remedy this situation and to propose a tenter, with the three-dimensional transformations of mats wrinkle-free and controlled possible.
Diese Aufgabe wird erfindungsgemäß durch die Merkmale des ersten Anspruchs gelöst. Die Lösung basiert auf der Erkenntnis, dass die Leisten, aus denen der Spannrahmen zusammengesetzt ist, aus elastischem Material bestehen wobei korrespondierende Leisten mit gegenpolig angeordneten Magneten ausgerüstet sind, insbesondere vorteilhaft ist es, die Leisten aus einem flexiblen magnetisierbaren Material zu machen, so dass die Matte zwischen dem geschlossenen Rahmen aufgrund der Magnetkraft eingespannt wird. Damit ist ein Nachfließen des Materials in Abhängigkeit des Umformgrades gewährleistet. Die Abhängigkeit von einem geringen linearen Kraftbereich von Federn ist damit vollkommen aufgehoben. Auch sorgt die Einspannung zwischen den beiden Leisten, dass sich beim Schließen des Werkzeuges keine Falten in der Matte bilden. Darüber hinaus ist die von den Magneten ausgeübte Normalkraft auf die Matte auch unabhängig von den Schließbewegungen des Spannrahmens.This object is achieved by the features of the first claim. The solution is based on the finding that the strips of which the clamping frame is composed of elastic material wherein corresponding strips are equipped with magnets arranged opposite to each other, it is particularly advantageous to make the strips of a flexible magnetizable material, so that the Mat is clamped between the closed frame due to the magnetic force. This ensures a subsequent flow of the material as a function of the degree of deformation. The dependence on a small linear force range of springs is thus completely eliminated. The clamping between the two strips also ensures that no wrinkles form in the mat when closing the tool. In addition, the force exerted by the magnet normal force on the mat is also independent of the closing movements of the tenter.
Die Unteransprüche beschreiben vorteilhafte Ausführungsformen der Erfindung.The subclaims describe advantageous embodiments of the invention.
Bevorzugt wird (Anspruch 2) als Material Federstahl. Damit ist es möglich, dass sich jede Leiste der Kontur des Werkzeuges anpassen kann. So kann der unbelastete Spannrahmen in seiner Kontur von der Kontur des Werkzeugrandes abweichen. Deshalb ist es möglich, die Matten faltenfrei auf den im Ruhezustand im Wesentlichen ebenen Spannrahmen abzulegen.Is preferred (claim 2) as a material spring steel. This makes it possible for each bar to adapt to the contour of the tool. Thus, the unloaded clamping frame may differ in its contour from the contour of the edge of the tool. Therefore, it is possible to place the mats wrinkle-free on the substantially flat clamping frame in the resting state.
Durch die Weiterbildung nach Anspruch 3 wird der Vorteil erzielt, dass die Matte im Bereich des Werkzeugrandes auf der Höhe des Werkzeugrandes liegt und nicht durch die Stärke der Leisten beabstandet ist.Through the development according to
Im Folgenden wird die Erfindung anhand eines bevorzugten Ausführungsbeispiels näher erläutert. Es stellen dar:In the following the invention will be explained in more detail with reference to a preferred embodiment. They show:

Wird eine Matte
Durch den Einsatz des erfindungsgemäßen Spannrahmens können Matten aus Glas-, Kohlenstofffasern- und Aramidrovings für komplexe Strukturen faltenfrei umgeformt werden. Damit wird eine Stückelung von Bauteilen in mehreren Substrukturen mit Überlappungen, die zu einem erheblichen Mehrgewicht führen, vermieden.By using the tenter according to the invention mats made of glass, carbon fiber and aramid rovings for complex structures can be formed wrinkle-free. This avoids a denomination of components in several substructures with overlaps, which leads to a considerable additional weight.
