Description

Die Erfindung betrifft eine Umformmaschine bzw. - Anlage mit den im Oberbegriff des Anspruchs angegebenen Mitteln.The invention relates to a forming machine or system with the means specified in the preamble of the claim.

Bei den Umformmaschinen handelt es sich um Stufenpressen, Karosseriepressen, Pressenlinien, Mehrstufenpressen, Transferpressen, auf denen Blechteile, auch großer Abmaße, zu z.B. Karosserieteilen geformt werden. Entsprechend der Größe der zu formenden Blechteile ist auch der Abstand der Bearbeitungsstufen voneinander und somit der Transportweg groß.The forming machines are multi-stage presses, body presses, press lines, multi-stage presses, transfer presses, on which sheet metal parts, even large dimensions, e.g. Body parts are molded. Depending on the size of the sheet metal parts to be formed, the distance between the processing stages and thus the transport path are large.

In der DE-A-39 05 068 ist eine Umsetzeinrichtung in einer Umformmaschine beschrieben mit nach jeder Bearbeitungsstufe vorgesehener Zwischenablage Die Umsetzbewegung der Blechteile erfolgt hier vermittels an in Laufschienen geführten Laufwager angebrachten Saugerbalken von einer Bearbeitungsstufe in eine Zwischenablage und aus dieser in die folgende Bearbeitungsstufe.DE-A-39 05 068 describes a transfer device in a metal-forming machine with a clipboard provided after each processing step.

In der gattungsbildenden DE-A-39 31 081 ist eine Zwischenablage beschrieben, auf denen Blechteile zwischenzeitlich abgelegt werden. Diese weist hierfür Schablonen auf, die höhermäßig und in ihrer Schräglage und in weiteren Bewegungen einstellbar ist. Eine dieser Bewegungen ist eine Korrekturbewegung für den Fehlerausgleich nach dem Schwenken des Bleches. Hierfür ist die den Aufbau der Zwischenablage tragende Aufbauplatte horizontal in Bichtung der Transferbewegung in Schienen gelagert und über ein Stellmittel, Motor und Spindel verschiebbar.In the generic DE-A-39 31 081 a clipboard is described, on which sheet metal parts are temporarily stored. For this purpose, this has templates which can be adjusted to a higher level and in their inclined position and in further movements. One of these movements is a correction movement for error compensation after swiveling the sheet. For this purpose, the mounting plate supporting the structure of the clipboard is mounted horizontally in the direction of the transfer movement in rails and can be displaced by means of an adjusting means, motor and spindle.

Demgegenüber ist es Aufgabe der Erfindung, zur Erhöhung der Hubzahlen der Umformmaschine bzw. -Anlage und zur Vergrößerung der zu transportierenden Blechteile einen Teilweg der Umsetzeinrichtung von der Zwischenablage auszuführen. Die Umsetzbewegung der Umsetzeinrichtung wird bewußt kürzer ausgeführt, so daß die Zwischenablage einen Teil der gesamten Umsetzstrecke übernimmt. Die Aufgabe ist gelöst durch die Merkmale des Patentanspruchs.In contrast, it is an object of the invention to increase the number of strokes of the forming machine or system and to enlarge the sheet metal parts to be transported from the transfer device the clipboard. The transfer movement of the transfer device is deliberately made shorter, so that the clipboard takes over part of the entire transfer path. The object is achieved by the features of the patent claim.

Die Vorteile der Erfindung sind neben der verbesserten Auslastung der Umformmaschine in der günstigeren Gestaltung der Umsetzeinrichtung unter Nutzung der Möglichkeiten der Zwischenablage zu sehen, ohne daß die Zwischenablage teurer oder komplizierter auszuführen ist. Wesentlich für die Erfindung ist hierbei das Loslösen von der bisherigen Überlegung, daß die Umsetzmittel die Gesamtbewegung der Blechteile bewirken müssen.In addition to the improved utilization of the forming machine, the advantages of the invention can be seen in the more favorable design of the transfer device using the possibilities of the clipboard, without the clipboard being more expensive or more complicated to implement. It is essential for the invention to be detached from the previous consideration that the transfer means must bring about the overall movement of the sheet metal parts.

Anhand eines in der Zeichnung gezeigten Ausführungsbeispiel soll im folgenden die Erfindung näher erläutert werden.Based on an embodiment shown in the drawing, the invention will be explained in more detail below.

Entsprechend Fig. 1 sind in einer Umformmaschine Werkzeuge, von denen die Werkzeugunterteile 1 und 2 angedeutet sind, über aus der Umformmaschine heraus- und in diese hineinverfahrbare Schiebetische 3 und 4 eingesetzt. Mittig zu der durch die Werkzeugunterteile 1 und 2 charakterisierten Bearbeitungsstufen ist eine Zwischenablage 12 angedeutet, die in der zu der DE-A-39 31 081 beschriebenen Weise zum Ausgleich des Fehlers beim Verdrehen der Schablonen 18, in die Position 18¹ mit dem aufliegenden Blechteil 7, 7¹ in den Positionen 12¹ versetzbar ist. Auf dem Werkzeugunterteil 1 liegt ein Blechteil 6 auf, das vermittels der aus der DE-A-39 05 068 bekannten Antriebs und Saugerbalken 9 in der Transferbewegung 13 umsetzbar und auf der Zwischenablage 12 in der Stellung 12 ablegbar ist. Gleichzeitig wird das auf den Schablonen 18 in die Lage 18' gedrehte und durch Bewegen der Zwischenablage in die Position 12¹ neu auf das Werkzeugunterteil 2 ausgerichtete Blechteil 7¹ vermittels Saugerbalken 11 in die Auflage auf dem Werkzeugunterteil 2 bewegt. Die Umsetzbewegung 13 bzw. 14 der Saugerbalken 9, 11, kann, wie in den Fign. 1, 2, 3 gezeigt, erfolgt in gleicher Bewegung, die Rückführbewegung 15 bzw. 16 kann antriebsbedingt unterschiedlich mit einer Bewegungsverzögerung im Bereich der Stützen 5 an den Schiebetischen 3, 4 während des Stößelniederganges erfolgen. Während Fig. 1 von einer Umsetzbewegung für die Blechteile 6, 7 ausgeht, die insgesamt von den Saugerbalken 9, 11 ausgeführt wird, zeigen die Fign. 2 und 3 diagrammartig die Umsetzbewegungs-und Rückbewegungsabläufe, die einen Teilweg 17 auslassen. Die Umsetzbewegung 13 in Fig. 2 beginnt mit der Entnahme des Blechteils aus dem Werkzeugunterteil und endet bereits weit vor der Position, halber Abstand zwischen bzw. mittig zu den Bearbeitungsstufen, dargestellt durch die Mitten der Werkzeugunterteile 1,2.According to FIG. 1, tools, of which the tool lower parts 1 and 2 are indicated, are inserted in a forming machine via sliding tables 3 and 4 which can be moved out of and into the forming machine. In the middle of the processing stages characterized by the lower tool parts 1 and 2, an intermediate storage space 12 is indicated, which in the manner described in DE-A-39 31 081 to compensate for the error when the templates 18 are rotated, into the position 18 1 with the sheet metal part 7 resting thereon , 7¹ can be moved to positions 12¹. On the lower tool part 1 there is a sheet metal part 6, which can be implemented in the transfer movement 13 by means of the drive and suction bar 9 known from DE-A-39 05 068 and can be stored in the position 12 on the clipboard 12. At the same time the sheet metal part 7 1 rotated on the stencils 18 into the position 18 ′ and moved by moving the clipboard into the position 12 1 to the lower tool part 2 by means of suction bars 11 into the support on the lower tool part 2. The conversion movement 13 or 14 of the suction bars 9, 11 can, as in FIGS. 1, 2, 3 shown, takes place in the same movement, the return movement 15 or 16 can take place differently due to the drive, with a movement delay in the area of the supports 5 on the sliding tables 3, 4 during the tappet descent. 1 is based on a conversion movement for the sheet metal parts 6, 7, which is carried out overall by the suction bars 9, 11, the FIGS. 2 and 3 diagrammatically the repositioning movement and return movement sequences which omit a partial route 17. The transfer movement 13 in FIG. 2 begins with the removal of the sheet metal part from the lower tool part and ends well before the position, half the distance between or in the middle of the machining stages, represented by the centers of the lower tool parts 1, 2.

Fig. 3 geht aus von einer größeren Umsetzbewegung 13 für z.B. ein größeres Blechteil. Die Werkzeugunterteile weisen demzufolge einen größeren Abstand zueinander auf als in Fig. 1 gezeichnet. Auch hier erfolgt die Ablage des aus dem Werkzeugunterteil 1 entnommenen und in den Bereich der Zwischenablage 12 umgesetzten Blechteils 6 bereits vor dem sich aus den Mitten der Werkzeugunterteile ergebenden halben Abstand. Den Fig. 2 und 3 ist gleichermaßen entnehmbar die Entnahme des Blechteils 7¹ weit hinter dem halben Werkzeugabstand, gesehen in Richtung der Umsetzbewegungen.Fig. 3 assumes a larger transfer movement 13 for e.g. a larger sheet metal part. The tool lower parts are therefore at a greater distance from one another than drawn in FIG. 1. Here too, the sheet metal part 6 removed from the lower tool part 1 and converted into the region of the intermediate storage 12 is already placed before the half distance resulting from the centers of the lower tool parts. 2 and 3 can be seen equally the removal of the sheet metal part 7¹ far behind half the tool distance, seen in the direction of the transfer movements.

Zur Überbrückung des von der Umsetzeinrichtung mit den Saugerbalken 9, 11 nicht überfahrenen Teilwegs 17 wird nunmehr die Zwischenablage 12 genutzt. Hierdurch ist es möglich, in die Rücklaufphase der Saugerbalken 9, 11, Rückbewegung 15, 16, eine Umsetzbewegung des auf der Zwischenablage 12 aufliegenden Blechteils 7¹ zu bewirken. Ebenso ist der Rücklauf der Zwischenablage 12 in die Übernahmeposition, linker Endbereich des Teilwegs 17, noch in die bereits einsetzende Umsetzbewegung, 13, 14 der Saugerbalken 9, 11 möglich.The clipboard 12 is now used to bridge the partial path 17 which is not traversed by the transfer device with the suction bars 9, 11. This makes it possible, in the return phase of the suction bars 9, 11, return movement 15, 16, to bring about a conversion movement of the sheet metal part 7 1 resting on the intermediate shelf 12. Likewise, the return of the clipboard 12 into the takeover position, left end region of the partial route 17, into the transfer movement 13, 14 of the suction bars 9, 11 already beginning is possible.

Fig. 4 zeigt die bereits aus den Fig. 1 bis 3 bekannten Mittel mit dem Teilweg 17. Mit 10 ist der Korrekturweg der Zwischenablage 12 positioniert, die keinen Teilweg darstellt, und die ohnehin aufgrund der Schräglagenänderung des Blechteils 7 auf den Schablonen gemäß der DE-A-39 31 081 auszuführen ist.FIG. 4 shows the means already known from FIGS. 1 to 3 with the partial path 17. The correction path of the clipboard 12, which does not represent a partial path, is positioned at 10 and which is due anyway the change in the inclined position of the sheet metal part 7 is to be carried out on the templates according to DE-A-39 31 081.

Die Umsetzbewegung des Blechteils 6 aus der links dargestellten Bearbeitungsstufe mit dem Werkzeugunterteil 1 in die rechts dargestellte Bearbeitungsstufe mit dem Werkzeugunterteil 2 erfolgt gemäß Fig. 4 wie folgt:
   Das aus dem Werkzeugunterteil 1 vermittels Saugerbalken 9 entnommene Blechteil 6 wird entsprechend dem Kurvenverlauf 13 in die rechts gezeigte Stellung gebracht. Den Abschluß bildet eine Absenkbewegung zur Auflage des Blechteils 6 auf den Schablonen 18. Zugleich mit der Entnahmebewegung und Umsetzbewegung 13 für das Blechteil 6 ist das Blechteil 7 von den Schablonen 18 der Zwischenablage 12 entnommen und in das Werkzeugunterteil 2 abgelegt worden. Die Entnahmestellung für das Blechteil 7 ist um den Teilweg 17 und den Korrekturweg 10 gegenüber der Ablegeposition der Zwischenablage 12 nach rechts, in Transferrichtung versetzt. Demzufolge wird auch das vermittels Saugerbalken 9 auf die Schablonen 18 der entgegen der Umsetzbewegung nach links bewegten Zwischenablage 12 in eine neue Schräglage gedreht, falls diese Bewegung erforderlich sein sollte, über den Teilweg 17 bewegt und die Korrekturbewegung vollzogen. Diese Bewegungen können parallel ablaufen. Der Saugerbalken 11 ist somit in die Position zu bringen zur Entnahme des Blechteils, hier 6, der durch die Position 12¹ der Zwischenablage gekennzeichnet ist.The conversion movement of the sheet metal part 6 from the processing stage shown on the left with the lower tool part 1 into the processing stage shown on the right with the lower tool part 2 takes place according to FIG. 4 as follows:
The sheet metal part 6 removed from the lower tool part 1 by means of the suction bar 9 is brought into the position shown on the right in accordance with the curve profile 13. The conclusion is a lowering movement for supporting the sheet metal part 6 on the stencils 18. Simultaneously with the removal movement and transfer movement 13 for the sheet metal part 6, the sheet metal part 7 has been removed from the stencils 18 of the clipboard 12 and placed in the lower tool part 2. The removal position for the sheet metal part 7 is offset by the partial path 17 and the correction path 10 to the right in the transfer direction with respect to the storage position of the clipboard 12. Accordingly, the squeegee 9 on the stencils 18 of the clipboard 12, which is moved to the left counter to the transfer movement, is also rotated into a new inclined position, if this movement should be necessary, via the partial path 17 and the correction movement is carried out. These movements can run in parallel. The suction bar 11 is thus to be brought into the position for removing the sheet metal part, here 6, which is characterized by the position 12 1 of the clipboard.

Fig. 5 zeigt zunächst eine Zwischenablage 12, wie aus der DE 39 31 08 A1 bekannt, die um die zum Lösen der Aufgabe erforderlichen Maßnahmen geändert worden ist. Ausgehend von der bekannten Ausführung sind die Änderungen hinzugezeichnet. Die Aufbauplatte 26 ist vermittels Führungen 27 auf Schienen 21 in Richtung der Umsetzbewegungen 13, 14 verschiebbar. Die Schienen 21 sind beiseitig um die Schienenteile 22 verlängert. Das Rahmengestell 19 ist in gleicher Weise verlängert auf die Größe, die mit 20 positioniert ist. Der Motor 23 war zu versetzen und die Spindel 24 zu verlängern auf die Gesamtlänge 25. Durch diese Maßnahmen ist die Übernahme des Teilweges 17 möglich. Die Zwischenablage kann mittig zu den Werkzeugunterteilen 1, 2 angeordnet sein. Durch den Verfahrweg dieser über den Teilweg 17 ist die Umsetzbewegung 13, 14 der Saugerbalken geringer als der halbe Abstand von Bearbeitungsstufe zu Bearbeitungsstufe.FIG. 5 first shows a clipboard 12, as known from DE 39 31 08 A1, which has been changed by the measures required to solve the task. Based on the known design, the changes are added. The mounting plate 26 can be displaced on the rails 21 in the direction of the transfer movements 13, 14 by means of guides 27. The rails 21 are extended on both sides by the rail parts 22. The frame 19 is extended in the same way to the size that is positioned at 20. The motor 23 had to be moved and the spindle 24 had to be extended to the total length 25. These measures made it possible to take over the partial route 17. The clipboard can be arranged centrally to the lower tool parts 1, 2. Due to the travel of this over the partial path 17, the transfer movement 13, 14 of the suction bars is less than half the distance from the processing stage to the processing stage.
