Abstract

The method involves forming the multiple small half shells with partial forms, which represent together a counter tool. The half shells are congruented to join in the contact zones. The half-shells are made of thermoplastic plastic. The half shells are of various sizes. The foil sections for the small half shells are clamped by negative pressure within a framework.

Description

Die Erfindung bezieht sich auf die Herstellung von Bauelementen mit einer Stabilität, die wesentlich durch ihre Form als Hohlkörper bestimmt ist.The The invention relates to the manufacture of components a stability essential by their shape as a hollow body is determined.

Dabei soll der Aufwand vermieden werden, der bislang durch die Herstellung jener Ausschnitte bedingt ist, mit denen der Hohlkörper auf die für die Stabilität erforderliche Restform reduziert wird.there the effort should be avoided, the hitherto by the production those sections is conditional, with which the hollow body to the rest form required for stability is reduced.

Objekte mit hoher Formstabilität, die durch sphärische Formung erreicht wird, können aufgrund der meist unvermeidlichen Hinterschnitte kaum in einem Stück durch Pressformung hergestellt werden.objects with high dimensional stability by spherical Forming can be achieved due to the mostly unavoidable Undercuts barely produced in one piece by press-forming become.

Soweit thermoplastische Materialien anwendbar sind, werden derartige Gegenstände meist durch Glasformung hergestellt, aber auch durch Tiefziehen zweier Folien, die im gleichen Arbeitsgang an Rändern und Stützpunkten miteinander verschweißt werden. (Twinsheet-Verfahren). Dann wird alles, bis auf die benötigte Schalenform, ausgeschnitten. Formteile für Flugzeugsitze oder Karosserieteile wie Radlaufkästen etc. aus thermoplastischen Kunststoffen werden vielfach so gefertigt.So far thermoplastic materials are applicable become such articles usually produced by glass molding, but also by deep drawing two foils, in the same operation on edges and Support points are welded together. (Twin Sheet process). Then everything is cut, except for the required shell shape. moldings for aircraft seats or body parts such as wheel arches etc. made of thermoplastic materials are often manufactured in this way.

Um derartige Formkörper funktionsgemäß herzustellen, müssen jedoch meist große Partien ausgeschnitten werden. Dies bedeutet nicht nur Materialverluste, sondern auch zusätzliche Arbeiten. Falls dazu nicht aufwendige Maschinen eingesetzt werden, fallen auch noch Finishing-Arbeiten, wie Entgraten, Beschleifen und Polieren an.Around to produce such shaped bodies functionally, however, they usually have to cut out large parts become. This not only means material losses, but also additional Work. If you do not use expensive machines, there are also finishing jobs, such as deburring, grinding and polishing.

Trotz dieser Nachteile gibt es aber bislang keine Technik, solche Teile mit geringerem Aufwand aus thermoplastischen Werkstoffen in einem Verfahrensschritt herzustellen. So werden kleinere Anbauelemente, wie Befestigungsteile und Flansche, bisher überwiegend mechanisch fixiert oder eingeklebt.In spite of However, there are no such technology, such parts with less effort from thermoplastic materials in one Produce process step. So are smaller attachments, like fasteners and flanges, so far mainly mechanically fixed or glued.

Hierbei ist es jedoch bei dreidimensional geformten Objekten oft ein Problem, die Teile genau anzubringen und maßhaltig zu verarbeiten. Deshalb wird auch dafür oftmals das Twinsheet-Verfahren eingesetzt, weil es hohe Maßhaltigkeit gewährleistet, obwohl später große Bereiche ausgeschnitten und entsorgt werden müssen.in this connection however, it is often a problem with three-dimensionally shaped objects to attach the parts accurately and process to size. That is why the Twinsheet method is often used used because it ensures high dimensional accuracy, though later large areas were cut out and disposed of Need to become.

Um diese Nachteile zu überwinden, wird die Twinsheet-Technik erfindungsgemäß nur in Fraktionen angewendet, was bislang – soweit bekannt – weder vorgeschlagen noch ausgeführt wurde.Around Overcoming these disadvantages is the twinsheet technique used according to the invention only in fractions, what has not been proposed so far - as far as known was still running.

Ein derartiges fraktionales Twinsheeting ist demnach die Verbindung eines durch Tiefziehen geformten Hauptelements mit einem oder mehreren kleineren, ebenfalls simultan tiefgezogenen Formteilen durch Pressen und Verschmelzen der Elemente in noch heißem Zustand, wie im Twinsheet-Verfahren üblich.One such fractional Twinsheeting is therefore the connection a formed by deep drawing main element with one or more smaller, also simultaneously thermoformed molded parts by pressing and fusing of the elements while still hot, as is common in the twinsheet process.

Es versteht sich, dass dabei die Form der Ränder und übrigen Kontaktzonen der kleinen Elemente der Form des Hauptelements an der für sie vorgesehenen Position kongruent sein müssen.It It is understood that while the shape of the edges and the rest Contact zones of the small elements of the shape of the main element their intended position must be congruent.

Die Formen der kleineren Elemente sind dazu auf einem oder mehreren Rahmen montiert und werden in einem der für die Ausführung der Twinsheet-Technik üblichen Verfahren (vergl. z. B. US-Patente 3.814.562 , 3.398.434 , 3.412.183 [mit waagrechtem Verschieben] oder US 5.620.715 , 6.379.606 , 6.086.354 [mit Karussell-Führung]) zueinander positioniert und miteinander verbunden.The shapes of the smaller elements are mounted on one or more frames and are in one of the usual for the execution of the twinsheet technique methods (see, eg. U.S. Patents 3,814,562 . 3398434 . 3412183 [with horizontal movement] or US 5,620,715 . 6379606 . 6086354 [with carousel guide]) positioned and connected to each other.

Dabei werden die kleineren Folienzuschnitte von hohl ausgeführten Rahmen gehalten, die in den Saug-Adapterrahmen des Trägers für die Teil-Werkzeuge montiert sind. Die Ränder dieser hohlen Rahmen sind auf der Unterseite gelocht, um bei Anwendung von Unterdruck die Folien an ihren Rändern anzusaugen.there The smaller foil blanks are made hollow Frame held in the suction adapter frame of the carrier are mounted for the part tools. The edges These hollow frames are perforated on the bottom to apply when applied of vacuum suck the films at their edges.

Durch die vom Rahmen umfasste Aussparung wird dann die jeweilige Fraktion des Tiefzieh-Werkzeug geführt, das die Formung des mit der Hauptschale jeweils zu verschweissenden Teilkörpers bewirkt.By the recess enclosed by the frame then becomes the respective fraction of the thermoforming tool, which is the shaping of the the main shell each to be welded part body causes.

Auch diese Teilform ist – wie beim Tiefziehen von thermoplastischen Folien üblich – durch Perforation mit dünnen Bohrungen oder Anwendung luftdurchlässigem Materials so ausgeführt, dass das erwärmte Folienstück durch Unterdruck in die Ausformung tiefgezogen wird, bevor die Verpressung mit dem Haupt-Formteil durch Zufahren des Werkzeuges in die Endstellung erfolgt.Also This part form is - as in deep drawing of thermoplastic Slides usual - by perforation with thin Drilling or using air permeable material like that executed that the heated foil piece is deep-drawn into the molding by negative pressure, before the compression with the main molding by moving the tool into the end position he follows.

Um eine ungleichmäßige Beheizung der Gesamtfläche des Hauptwerkzeuges zu vermeiden, erfolgt eine verstärkte Heizung dieser Werkzeugfraktionen entweder durch auf diese Teilflächen gerichtete, verstärkte oder höher angesteuerte Heizelemente, oder durch Schablonen, die die Einstrahlung der Heizelemente für Bereiche außerhalb dieser Fraktionen beschränken.Around an uneven heating of the total area to avoid the main tool, a reinforced Heating of these tool fractions either through these sub-areas directed, amplified or higher-powered Heating elements, or by stencils, the radiation of the heating elements for areas outside these fractions.

Weiter ist es unter sich ändernden Prozessbedingungen manchmal erforderlich, die Einzelwerkzeuge in der Endstellung unterschiedlich zu positionieren, um einen gleichmäßigen, oder gelegentlich auch leicht unterschiedlichen Andruck der Formteile aneinander zu erzielen, damit eine sichere Verschweißung gewährleistet ist.Further It is sometimes under changing process conditions required, the individual tools in the end position different to position a steady, or occasionally also slightly different pressure of the moldings together to achieve a secure weld is.

Diese Anpassung kann durch mechanische Einstellglider erfolgen. Da sich aber sowohl die Werkzeuge, wie auch die eingespannten Folien im Prozessverlauf – z. B. durch thermische Einflüsse – unterschiedlich verformen können, ist es vorteilhaft, diese dynamisch anzupassen.This adjustment can be done by mechanical Einstellglider. But since both the tools, as well as the clamped slides in Pro measuring process - z. B. by thermal influences - can deform differently, it is advantageous to adapt them dynamically.

Dies kann bei laufender Prüfung des Produktgebnisses mit der Erfahrung des Maschinenführers durch Fernbedieneng erfolgen.This can be checked while the product result is being checked with the Experience of the machine operator by Fernbedieneng done.

In einer weiter fortgeschrittenen Ausführung wird jedoch laufend der Abstand und/oder der Druck zwischen den zusammengefahrenen Werkzeuge gemessen, um sie zueinander entsprechend nachzupositionieren.In however, a more advanced implementation will be ongoing the distance and / or pressure between the tools together measured to postpone each other accordingly.

Die Messungen können mit Abstandssensoren und Drucksensoren erfolgen, die bevorzugt an kritische Punkten, insbesondere an den Werkzeugrändern, einmontiert sind.The Measurements can be made with distance sensors and pressure sensors take place, preferably at critical points, in particular at the Tool edges, are einmontiert.

Die dynamische Nachjustierung der Werkzeuge wird vorzugsweise an den einzelnen Teilwerkzeugen erfolgen. Denkbar ist aber auch, das Hauptwerkzeug des großen Formteils entsprechend punktuell zu unterstützen, oder seine horizontale Positionierung oder seinen Sturz leicht zu verändern. Es wird dazu vorzugsweise durch ein Raster von Aktuatoren angepasst, die auf seiner Rückseite gegen eine zweite Rückwand oder den Vorschubtisch abgestützt sind.The dynamic readjustment of the tools is preferably to the individual sub-tools done. It is also conceivable, the main tool to selectively support the large molding accordingly, or its horizontal positioning or its fall easily too change. It is for this purpose preferably by a grid of Adjusted actuators on its back against a second Rear wall or the feed table are supported.

Diese Justierungen können mit den dem Fachmann bekannten Techniken an pneumatisch oder elektrisch betätigten Stellgliedern (vernehmlich mit Schraub- oder Spindelbetätigung), oder hydraulischen Elementen, erfolgen.These Adjustments can be made using the techniques known to those skilled in the art on pneumatically or electrically actuated actuators (pronounced with screw or spindle operation), or Hydraulic elements, done.

Dazu wird vorgeschlagen, Messergebnisse und Aktuatorenstellung in einer leichtfasslichen grafischen Form aufzubereiten und bevorzugt an einen Berührungsempfindlichen Bildschirm (Touchscreen) bedienbar zu machen.To It is proposed to provide measurement results and actuator position in one easy to prepare graphic form and prefers a touch-sensitive screen (touch screen) can be operated close.

Dies kann z. B. dadurch geschehen, dass das Werkzeug aus der CAD-Zeichnung oder durch grafisches Einscannen erfasst und als Bildschirm-Hintergrund angelegt wird.This can z. B. done by the tool from the CAD drawing or captured by graphical scanning and as a screen background is created.

Die Messpunkte werden darauf projiziert, und ihre Werte z. B. durch Farbgebung indiziert. Im Falle von Druckmessungen können angestrebte Normwerte z. B. weiß oder schwarz, höherer Druck orange bis rot, geringerer Druck aber türkis bis blau dargestellt werden.The Measurement points are projected onto it, and their values z. B. by Coloring indicated. In the case of pressure measurements can desired standard values z. White or black, higher Pressure orange to red, lower pressure but turquoise to be displayed in blue.

Die Aktuatoren sind vorzugsweise als Rahmen angezeigt, die mit Touchscreen-Technik durch Berührung anwählbar sind. Jeder Aktor kann dann durch ein geeignetes Stellglied wie einem Joystick, Trackball, oder das Anklicken der gewünschten Position auf einer Skala mit dem Mauszeiger justiert werden. Dabei ist die Wirkung der Justierung jeweils an den angezeigten Messpunkten zu überwachen.The Actuators are preferably displayed as frames using touchscreen technology can be selected by touch. Every actor can then by a suitable actuator such as a joystick, trackball, or clicking the desired position on a scale be adjusted with the mouse pointer. Here is the effect of the adjustment each at the displayed measuring points to monitor.

In einer weiteren Ausgestaltung ist es möglich, die Messwerte z. B. entlang der Werkzeugränder zwischen den Messpunkten zu interpolieren und den Verlauf als farblich sich ändernde Werkzeugkontur anzuzeigen.In In a further embodiment, it is possible to use the measured values z. B. along the tool edges between the measuring points to interpolate and the course as changing color Display tool contour.

Die Erfindung wird anhand nachfolgender Zeichnungen näher beschrieben:The The invention will be described in more detail with reference to the following drawings:

1 bis 3 zeigen als Referenz die bisher übliche Anwendung des Twinsheet-Verfahrens, um z. B. nur einen rechteckigen Flansch auf einer sphärisch geformten Basisplatte zu realisieren, während 4 die Lösung gemäß der nachfolgenden Patentansprüche darstellt. 1 to 3 show for reference the hitherto customary application of the Twinsheet method to z. B. to realize only a rectangular flange on a spherical base plate, while 4 represents the solution according to the following claims.

1 zeigt die Ausgangssituation im konventionellen Verfahren:
Eine unteres Werkzeug 1, in das die Folie 2 durch Unterdruck zur Herstellung der Basisplatte tiefgezogen werden soll. Sie wird zunächst, ebenso wie die zweite Folie 3 durch den Unterdruckrahmen 4 gehalten. Darüber ist das obere Werkzeug 5 (in Zeichnung 1a zur besseren Erkennbarkeit umgedreht gezeigt) auf eine entsprechend große Grundplatte 6 montiert. 1 shows the starting situation in the conventional procedure:
A lower tool 1 into which the film 2 should be thermoformed by vacuum to produce the base plate. It will be first, as well as the second slide 3 through the vacuum frame 4 held. Above that is the upper tool 5 (Shown in Figure 1a reversed for better visibility) on a correspondingly large base plate 6 assembled.

2 zeigt das Zwischenergebnis des konvenionellen Twinsheetings: Nach Tiefziehen und Zusammenfahren des unteren Werkzeugs 1 und des oberen Werkzeugs 2 in 1 sind die zwei miteinander verbundenen Teile entstanden: Die Basisplatte 7 und der mit ihr verbundene Flansch 8, der jedoch noch Teil der oberen Folie 3 ist, die an der Schnittline 9 durchtrennt werden muss. Der größte Teil der Folie 3 muss dann entsorgt werden. 2 shows the intermediate result of the conventional Twinsheetings: After deep drawing and collapse of the lower tool 1 and the upper tool 2 in 1 The two interconnected parts were created: The base plate 7 and the flange connected to it 8th , but still part of the top film 3 that's at the cutting line 9 must be severed. The largest part of the slide 3 must then be disposed of.

3 zeigt das daraus resultierende, verbundene Formteil 10 mit der Basisplatte 7 und dem nunmehr darauf fest verbundenen 2 Flansch 8. 3 shows the resulting bonded molding 10 with the base plate 7 and now firmly attached to it 2 flange 8th ,

4 stellt dar, wie dies erfindungsgemäß in vereinfachter Form auszuführen ist:
Das Untere Werkzeug ist gleich wie in 1, ebenso die zugehörige Folie 2. 4 illustrates how this is carried out according to the invention in a simplified form:
The lower tool is the same as in 1 , as well as the corresponding foil 2 ,

In den Rahmen 4 ist hier jedoch ein zweiter, kleinerer Unterdruck-Rahmen 11 eingefügt, der eine kleinere Folie 12 festhält.In the frame 4 Here, however, is a second, smaller vacuum frame 11 Inserted a smaller slide 12 holds.

Das obere Werkzeug formt diese kleine Folie 12 durch Unterdruck an sich an und fahrt durch den kleinen Rahmen 11 hindurch, um sie mit der unteren Basisfolie 2 zu verpressen und damit zu verschweißen.The upper tool forms this little foil 12 by negative pressure and drive through the small frame 11 pass it to the bottom base film 2 to be pressed and welded with it.

Das Ergebnis ist wie das Formteil 10 in 3, nur dass kein Ausschneiden erforderlich war und wesentlich weniger Foliernmaterial verbraucht wurde.The result is like the molding 10 in 3 except that no cutting was required and much less filming material was consumed.

5 zeigt die Darstellung der Formung an einem Steuer-Bildschirm 12: die Kontur des Unterwerkzeugs 13 und des Oberwerkzeugs 14 mit den Indikatoren 15, 18 und 19 für Unterdruck und -Temperatur der Verschweißzonen, sowie Überdruck bei 16 und 17, sowie Berührfelder 20 zur Anwahl der in diesen Bereichen positionierten Aktuatoren zur Verstellung bzw. Ausrichtung der Werkzeugs. 5 shows the representation of the shaping on a control screen 12 : the contour of the lower tool 13 and the upper tool 14 with the indicators 15 . 18 and 19 for underpressure and temperature of the welding zones, as well as overpressure at 16 and 17 , as well as touch fields 20 for selecting the actuators positioned in these areas for adjustment or alignment of the tool.
