Description

Die Erfindung betrifft ein Werkzeug zum Hinterschäumen von platten- oder schalenförmigen Werkstücken gemäß des Oberbegrif­ fes des Patentanspruches.The invention relates to a tool for back foaming plate or bowl-shaped workpieces according to the general concept fes of claim.

Ein Werkzeug der gattungsgemäßen Bauart ist aus der DE-OS 41 37 454 bekannt. Das Werkzeug ist zweigeteilt, wobei im oberen Werkzeugteil das zu hinterschäumende Werkstück aufgenommen ist. Die Konturen der dem Werkstück zugewandten Seite des oberen Werkzeugteils und des Werkstückes sind dabei exakt aufeinander abgestimmt. Weist das Werkstück jedoch Formtoleranzen auf, er­ geben sich beim Einlegen des Werkstückes im Werkzeugteil Ver­ spannungen und Verzüge und dadurch ein nicht exakt lagedefi­ niertes Anliegen des Werkstückes im Werkzeug. Dies führt zu entsprechenden Formtoleranzen beim Hinterschäumen, so daß bei der Fertigung vermehrt Ausschußteile erzeugt werden. Eine Möglichkeit, derartige Verspannungen des Werkstückes im Werk­ zeugteil zu verhindern, besteht in der Nachbearbeitung des das Werkstück herstellenden Werkzeuges, sofern die Abweichungen ständig gleich ausfallen. Dies ist jedoch fertigungstechnisch aufwendig und kostspielig.A tool of the generic type is from DE-OS 41 37 454 known. The tool is divided into two, the upper one Tool part the workpiece to be foamed is picked up. The contours of the side of the upper side facing the workpiece The tool part and the workpiece are exactly on top of each other Voted. However, if the workpiece has shape tolerances, he give themselves when inserting the workpiece in the tool part Ver tensions and delays and therefore an inaccurate position The workpiece is in contact with the tool. this leads to to corresponding shape tolerances when back foaming, so that rejects are increasingly being produced during production. A Possibility of tensioning the workpiece in the factory Preventing the tool part consists in the post-processing of the Workpiece manufacturing tool, provided the deviations always turn out the same. However, this is manufacturing technology complex and costly.

Desweiteren ist aus der DE-OS 21 19 874 ein Werkzeug zum Aus­ schäumen von hohlen Werkstücken bekannt, wobei in einen das Werkstück mit Abstand umgebenden Formkasten über ein Fluid ein Abstützdruck für das Werkstück allseitig einsteuerbar ist, der mit dem jeweils herrschenden Schäumdruck übereinstimmt und die Formtreue des Werkstückes gewährleistet. Das Werkzeug läßt sich jedoch nicht zum Hinterschäumen von platten- oder schalenförmi­ gen Werkstücken verwenden.Furthermore, from DE-OS 21 19 874 a tool to stop foaming of hollow workpieces known, in one of which Work piece with a surrounding mold box using a fluid Support pressure for the workpiece can be controlled on all sides corresponds to the prevailing foam pressure and the  Guaranteed shape accuracy of the workpiece. The tool can be however not for back foaming of plate or bowl-shaped use workpieces.

Der Erfindung liegt die Aufgabe zugrunde, ein gattungsgemäßes Werkzeug dahingehend weiterzubilden, daß eine verspannungs- und verzugsfreie sowie eine reproduzierbare exakt lagedefinierte Anlage des Werkstückes im Werkzeug auch bei Formtoleranzen des Werkstückes mit nur geringem Aufwand erreichbar ist.The invention has for its object a generic Develop tool in such a way that a tension and distortion-free as well as a reproducible, precisely defined position Creation of the workpiece in the tool even with shape tolerances of the Workpiece can be reached with little effort.

Die Aufgabe ist erfindungsgemäß durch die kennzeichnenden Merk­ male des Patentanspruches gelöst.The object is according to the invention by the characterizing note male solved the claim.

Dank der nur punktuellen mechanischen Abstützung im Zusammen­ wirken mit der fluidischen Abstützung mittels einer Membran, die beim Einsteuern eines dem Schäumdruck entgegenwirkenden Abstützdruckes in die Bereiche zwischen den punktuellen Abstüt­ zungen sich der Kontur des Werkstückes genau anpaßt, kommt das Werkstück - auch wenn es Formtoleranzen aufweist - ohne großen fertigungstechnischen Aufwand verspannungs- und verzugsfrei sowie reproduzierbar exakt lagedefiniert im Werkzeug zur Anla­ ge. Dadurch werden zusätzliche Formtoleranzen beim Hinterschäu­ men vermieden, so daß die Rate an nicht weiter verwendbaren Ausschußteilen wesentlich reduziert wird. Aufgrund der dabei gewonnenen höheren Arbeitsgenauigkeit beim Hinterschäumen des Werkstückes können preisgünstigere Werkstücke mit größeren Formtoleranzen zur Weiterverarbeitung ohne Erhöhung der Aus­ schußrate zugelassen werden. Ferner sind nur noch die Abstütz­ punkte maßlich zu überwachen, wodurch sich der Kontrollaufwand bezüglich der Abmessungen der Werkzeugkonturen wesentlich ver­ ringert. Thanks to the only selective mechanical support in combination act with the fluidic support by means of a membrane, those which counteract the foam pressure when controlling Support pressure in the areas between the selective support tongues adapts exactly to the contour of the workpiece, that comes Workpiece - even if it has shape tolerances - without large manufacturing effort without tension and distortion as well as reproducibly precisely defined in the tool for the system ge. This creates additional shape tolerances when looking behind men avoided so that the rate of no longer usable Committee parts is significantly reduced. Because of that gained higher accuracy when foaming the Workpiece can be cheaper workpieces with larger ones Shape tolerances for further processing without increasing the out shot rate are allowed. Furthermore, only the supports dimensionally monitor points, which increases the control effort ver with respect to the dimensions of the tool contours wrestles.  

In der nachfolgenden Zeichnungsbeschreibung wird ein Ausfüh­ rungsbeispiel der Erfindung näher erläutert. Dabei zeigt die Figur in einer Schnittdarstellung das erfindungsgemäße Werkzeug mit einem in ihm eingelegten schalenförmigen und mit Schaum beaufschlagten Werkstück.In the following description of the drawing, an exec Example of the invention explained in more detail. The shows Figure in a sectional view of the tool according to the invention with a bowl-shaped inlay and with foam loaded workpiece.

In der Figur ist ein Werkzeug 1 dargestellt, das aus einem ersten Teil 2 und einem zweiten unter dem Werk­ zeugteil 2 liegenden Teil 3 zusammengefügt ist. Diese bilden miteinander einen geschlossenen Schäumraum 4 zum Hinterschäumen eines schalenförmigen Werkstückes 5 aus.In the figure, a tool 1 is shown, which consists of a first part 2 and a second below the tools part 2 part is assembled. 3 Together they form a closed foam space 4 for back-foaming a bowl-shaped workpiece 5 .

Das Werkstück 5 besteht aus einem Aluminium- oder Stahlblech, alternativ aus Kunststoff, und dient als Versteifungselement für ein geschäumtes Verbundbauteil, das beispielsweise als Handschuhkastendeckel oder Armaturentafel in einem Kraftfahr­ zeug verwendet wird.The workpiece 5 consists of an aluminum or steel sheet, alternatively made of plastic, and serves as a stiffening element for a foamed composite component which is used, for example, as a glove box cover or instrument panel in a motor vehicle.

Die Werkzeugteile 2 und 3 sind an ihren einander zugekehrten Seiten 6, 7 der Kontur des Werkstückes 5 entsprechend gestaltet, wobei in die Seite 7 zur Ausbildung des Schäumraumes 4 eine zum Werkstück 5 formpositive Mulde 8 eingearbeitet ist. In die Mul­ de 8 ist eine Dekorfolie 9 eingelegt, welche an deren Kontur formschlüssig anliegt.The tool parts 2 and 3 are designed on their mutually facing sides 6, 7 in accordance with the contour of the workpiece 5 , wherein a recess 8 which is positive in shape with respect to the workpiece 5 is incorporated into the side 7 to form the foam space 4 . In the Mul de 8 , a decorative film 9 is inserted, which bears positively on its contour.

In die Seite 6 sind Aussparungen 10 eingearbeitet, die sich bis auf wenige in den Schäumraum 4 hineinragende als Abstützpunkte für das Werkstück 5 dienende Erhebungen 11 über die gesamte Kontur der Seite 6 erstrecken. Die Aussparungen 10 werden von einer am Werkzeugteil 2 angeordneten Membran 12 dichtend über­ spannt.Recesses 10 are worked into the side 6 , which extend over the entire contour of the side 6 apart from a few elevations 11 which protrude into the foam space 4 and serve as support points for the workpiece 5 . The recesses 10 are sealingly stretched over by a membrane 12 arranged on the tool part 2 .

Das Werkstück 5 wird vor dem Zusammenfügen der beiden Werkzeug­ teile 2, 3 über die Erhebungen 11 gespannt. Die Erhebungen 11 weisen jeweils eine ebene Anlagefläche am Werkstück 5 auf, die zur Vermeidung von Verspannungen und Verzügen beim Einsetzen ins Werkzeugteil 2 möglichst klein gehalten ist. Die Erhebungen sind dabei nur an den Stellen ausgebildet, die für die Lagede­ finition und spätere Montage des Werkstückes 5, wie beispiels­ weise an den Anschraubpunkten, wichtig sind. Das Werkstück 5 wird somit im ersten Werkzeugteil 2 rückseitig nur noch an wenigen Stellen punktuell mechanisch abgestützt. The workpiece 5 is clamped over the elevations 11 before joining the two tool parts 2 , 3 . The elevations 11 each have a flat contact surface on the workpiece 5 , which is kept as small as possible to avoid tension and warping when inserted into the tool part 2 . The surveys are formed only at those points which are important for the position definition and later assembly of the workpiece 5 , such as at the screwing points. The workpiece 5 is thus only mechanically supported at a few points on the back of the first tool part 2 .

Die Membran 12 bildet mit den Aussparungen 10 Abstütztaschen 13, die über eine durch das erste Werkzeugteil 2 hindurchfüh­ rende Verbindungsleitung 14 mit einer extern angeordneten Drucksteuervorrichtung 15 und einer Druckquelle 16 fluidisch in Verbindung stehen. Bei Einsteuerung eines Druckes paßt sich die Membran 12 genau der Form des Werkstückes 5 an, so daß dieses rückseitig auch in den zwischen den mechanischen Abstützpunkten liegenden Bereichen verspannungs- und verzugsfrei abgestützt ist.The membrane 12 forms with the recesses 10 support pockets 13 , which are in fluid communication with an externally arranged pressure control device 15 and a pressure source 16 via a connecting line 14 leading through the first tool part 2 . When a pressure is applied, the membrane 12 adapts exactly to the shape of the workpiece 5 , so that it is supported on the back also in the areas lying between the mechanical support points without tension and distortion.

Zum Hinterschäumen des Werkstückes 5 wird in die folienbespann­ te Mulde 8 des zweiten Werkzeugteils 3 ein expandierendes Schaummittel 17 eingefüllt. Danach werden die beiden Werkzeug­ teile 2, 3 zusammengefügt, wobei der Abstützdruck der fluidi­ schen (hydraulischen oder pneumatischen) Abstützung des Werk­ stückes 5 zur Verhinderung einer Deformierung des Werkstückes von der Drucksteuervorrichtung 15 derart gesteuert werden muß, daß er mit dem gerade herrschenden Schäumdruck übereinstimmt.To back-foam the workpiece 5 , an expanding foaming agent 17 is filled into the film-covered depression 8 of the second tool part 3 . Then the two tool parts 2 , 3 are joined together, the support pressure of the fluidic's (hydraulic or pneumatic) support of the workpiece 5 to prevent deformation of the workpiece from the pressure control device 15 must be controlled such that it matches the foam pressure currently prevailing .
