Abstract
Description
Die Erfindung betrifft im weiteren Sinne eine Pressenanlage und im engeren Sinne eine Transferpresse, wie sie insbesondere zur Herstellung von großen Blechteilen, beispielsweise Karosserieteilen, eingesetzt wird.The invention in a broader sense relates to a press plant and, in the narrower sense, a transfer press, as used in particular for the production of large sheet metal parts, for example body parts.
Transferpressen weisen mehrere Pressenstufen auf, die das Werkstück nach einander durchläuft. Zum Transport der Werkstücke dient dabei eine Saugereinrichtung, die beispielsweise mit Saugerbrücken bestückt ist, und mit diesen die Werkstücke von Pressenstufe zu Pressenstufe transportiert. Die Pressenstufen sind dabei in einem gegeben Raster angeordnet, d.h. die Mittenabstände der Pressenstufen sind untereinander gleich.Transfer presses have several press stages, which passes through the workpiece in succession. To transport the workpieces serves a suction device that is equipped, for example, with suction bridges, and transported with these the workpieces from press stage to press stage. The press stages are arranged in a given grid, i. the center distances of the press stages are equal to each other.
Es ist Aufgabe der Erfindung, bei Transferpressen oder ähnlichen Pressenanlagen eine Möglichkeit der flexibleren Gestaltung unter Beibehaltung des einheitlichen Transfers zu schaffen.It is an object of the invention to provide in transfer presses or similar presses a possibility of more flexible design while maintaining the uniform transfer.
Diese Aufgabe wird mit der Pressenanlage nach Anspruch 1 gelöst:
- Die erfindungsgemäße Pressenanlage weist zumindest eine Presse mit wenigstens einer Pressenstufe und zumindest eine Mehrstationenpresse mit zwei oder auch mehreren Pressenstufen auf. Die Presse und die Mehrstationenpresse können Teile einer Transferpresse wie auch einer sonstigen Pressenanlage sein. Zwischen der Presse und der Mehrstationenpresse ist ein Abstand vorgesehen, der ein nicht ganzzahliges Vielfaches des Pressenstufenabstands ist. Als Abstand wird dabei jeweils der Werkzeugmittenabstand verstanden. Zum Ausgleich dieses Abstandsunterschieds ist zwischen der Presse und der Mehrstationenpresse eine Ablagestufe angeordnet, die in Transferrichtung gesteuert verfahrbar ist. Der Verfahrweg der Ablagestufe addiert oder subtrahiert sich zu der Länge der anschließenden Transferschritte und ergibt somit genau den Pressenstufenabstand zwischen Presse und Mehrstationenpresse.
- The press installation according to the invention has at least one press with at least one press stage and at least one multi-station press with two or more press stages. The press and the multi-station press can be parts of a transfer press as well as of other press systems. Between the press and the multi-station press a distance is provided which is a non-integer multiple of the press step distance. The distance is understood in each case the tool center distance. To compensate for this difference in distance, a storage stage is arranged between the press and the multi-station press, which can be moved controlled in the transfer direction. The travel path of the filing step adds or subtracts to the length of the subsequent transfer steps and thus gives exactly the press stage distance between press and multi-station press.
Die Transfereinrichtung ist vorzugsweise so eingerichtet, dass ihr Transferschritt über die gesamte Länge der Transfereinrichtung einheitlich ist und mit dem Pressenstufenabstand der Mehrstationenpresse übereinstimmt.The transfer device is preferably set up so that its transfer step is uniform over the entire length of the transfer device and coincides with the press step spacing of the multi-station press.
Vorzugsweise sind auch die Greifermittel der Transfereinrichtung in Abständen gehalten, die mit dem Pressenstufenabstand übereinstimmen. Die Greifermittel führen vorzugsweise eine zueinander synchrone Bewegung aus. Im einfachsten Falle führen sie eine gleiche Bewegung aus. Beispielsweise können die Greifermittel Saugerbrücken sein, die an Transferstangen befestigt sind. Der Antrieb der Transfereinrichtung erfolgt vorzugsweise über NC-gesteuerte Servomotoren und zwar sowohl in horizontaler Transferrichtung als auch in vertikaler Hebe- und Senkrichtung. Durch Überlagerung der Bewegung in Transferrichtung und in Vertikalrichtung werden die gewünschten Transferkurven erzielt, bei deren Durchlauf ein Blechteil aus einem Werkzeug heraus gehoben zu dem nächsten Werkzeug transportiert und in diesem abgelegt wird.Preferably, the gripping means of the transfer means are held at intervals which coincide with the press stage spacing. The gripper means preferably perform a mutually synchronous movement. In the simplest case, they perform the same movement. For example, the gripper means may be suction bridges fixed to transfer bars. The drive of the transfer device is preferably carried out via NC-controlled servomotors, both in the horizontal transfer direction and in the vertical lifting and lowering direction. By superimposing the movement in the transfer direction and in the vertical direction, the desired Transfer curves achieved in the passage of a sheet metal part lifted out of a tool to the next tool and stored in this.
Mit dieser Transferbewegung kann das Werkstück bzw. Blechteil auch auf der Ablagestufe abgelegt werden, die das Blechteil dann von einer ersten Position zu einer zweiten Position in Transferrichtung verfährt, aus der es dann von dem nächsten Greifermittel der Transfereinrichtung abgeholt werden kann, um dem nächsten Werkzeug zugeführt zu werden. Der Verfahrhub der Ablagestufe wird vorzugsweise während des Arbeitshubs der Presse und Mehrstationenpresse durchgeführt. Die Bewegung der Ablagestufe ist vorzugsweise eine reine Linearbewegung. Die Bewegung wird auf die Bewegung der Greifermittel der Transfereinrichtung synchronisiert.With this transfer movement, the workpiece or sheet metal part can also be deposited on the storage stage, which then moves the sheet metal part from a first position to a second position in the transfer direction, from which it can then be picked up by the next gripper means of the transfer device to the next tool to be fed. The Verfahrhub the filing stage is preferably carried out during the working stroke of the press and multi-station press. The movement of the filing stage is preferably a pure linear movement. The movement is synchronized to the movement of the gripper means of the transfer device.

FIG. 1 a multi-station transfer press with non-uniform press step distances, in a schematic side view,
In
Auf dem Pressentisch 4 oder einem entsprechenden anderen unteren Abschnitt des Pressengestells sind Schiebetische 11, 12 gelagert, die jeweils unterhalb der Stößel 9, 10 angeordnet sind. In der Presse 2 ist ein Werkzeug angeordnet, dessen oberer Werkzeugteil 13 mit dem Stößel 9 verbunden ist und dessen unterer Werkzeugteil 14 auf dem Schiebetisch 11 ruht.On the press table 4 or a corresponding other lower portion of the press frame sliding tables 11, 12 are mounted, which are each arranged below the
Der Stößel 10 der Mehrstationenpresse 3 trägt zwei oder mehrere, im vorliegenden Ausführungsbeispiel vier, obere Werkzeugteile 15, 16, 17, 18. Der Schiebetisch 12 trägt entsprechend darunter angeordnete untere Werkzeugteile 19, 20, 21, 22.The
Die Werkzeugteile 13 bis 22 legen jeweils Pressenstufen fest und zwar eine erste Pressenstufe 23 für die Presse 2 und nachfolgende Pressenstufen 24, 25, 26, 27 für die Mehrstationenpresse 3. Die Mitten der Pressenstufen 23 bis 27 sind in
Die Pressenstufen 24 bis 27 der Mehrstationenpresse 3 stehen in einem einheitlichen Pressenstufenabstand a zueinander. Die Pressenstufe 23 der Presse 2 und die nächstfolgende Pressenstufe 24 der Mehrstationenpresse 3 stehen jedoch in einem Abstand b zueinander, der weder mit dem Pressenstufenabstand a übereinstimmt noch das Doppelte oder Dreifache oder allgemein gesprochen ein ganzzahliges Vielfaches von diesem ist.The press stages 24 to 27 of the multi-station press 3 are at a uniform press stage distance a to each other. However, the press stage 23 of the press 2 and the next press stage 24 of the multi-station press 3 are at a distance b to each other, which does not coincide with the press stage distance a nor is double or triple or, generally speaking, an integer multiple of this.
Zu der Transferpresse 1 gehört eine Transfereinrichtung 28, die beispielsweise zwei sich längs und horizontal über alle Pressenstufen 23 bis 27 hinweg erstreckende Transferschienen 29 aufweist. Die Transferschienen 29 sind beispielsweise parallel zueinander vor und hinter den Werkzeugen angeordnet. Sie können Laufwagen tragen, die untereinander durch Saugerbrücken verbunden sind. Von den Saugerbrücken stehen Sauger 30 bis 36 ab, die von oben her Blechteile fassen und halten können. Die Sauger 30 bis 36 bilden Greifermittel, die, wie aus
Zwischen der Presse 2 und der Mehrstationenpresse 3 ist eine Ablagestufe 37 angeordnet, die eine Aufnahme 38 für die Werkstücke aufweist. Die Aufnahme kann entsprechende Trägerelemente umfassen, die dem Profil des aufzunehmenden Werkstücks (Blechteils) angepasst sind, so dass dieses sicher auf der Aufnahme 38 abgelegt werden kann.Between the press 2 and the multi-station press 3, a storage stage 37 is arranged, which has a receptacle 38 for the workpieces. The receptacle may comprise corresponding carrier elements, which are adapted to the profile of the male workpiece (sheet metal part), so that it can be safely stored on the receptacle 38.
Zu der Ablagestufe 37 gehört eine in
Die insoweit beschriebene Transferpresse 1 arbeitet wie folgt:
- In der Transferpresse 1 nach
Figur 1 bewegen sich die Stößel 9 und 10 der Presse 2 und der Mehrstationenpresse 3 synchron auf und ab. Jeweils bei geöffneten Werkzeugen, d.h. wenn dieStößel 9, 10 sich in einem oberen Teil ihrer Bewegungskurve befinden, fahren die Greifermittel 31 bis 36 in die entgegen der Transferrichtung liegenden geöffneten Werkzeuge ein (d.h. inFigur 1 nach rechts), nehmen dort die Werkstücke auf und führen sie in einem flachen Bogen zu dem Werkzeug der nächstfolgenden Pressenstufe und legen sie dort ab, um danach wieder in Ruheposition zurückzukehren. Im einzelnen läuft der Sauger 31 in das Werkzeug der Pressenstufe 23. Der Sauger 33 läuft in das Werkzeug der Pressenstufe 24.Der Sauger 34 läuft in das Werkzeug der Pressenstufe 25 und so weiter.
- In the transfer press 1 after
FIG. 1 move theplunger 9 and 10 of the press 2 and the multi-station press 3 synchronously up and down. When the tools are open, ie when theplungers 9, 10 are located in an upper part of their movement curve, the gripping means 31 to 36 move into the open tools opposite to the transfer direction (ie in FIGFIG. 1 to the right), pick up the workpieces there and guide them in a flat arc to the tool of the next press stage and place them there, then return to their resting position. Specifically, the sucker 31 runs in the tool of the press stage 23. The sucker 33 runs in the tool of the press stage 24. Thesucker 34 runs in the tool of the press stage 25 and so on.
Während beim Transferprozess der Sauger 33 das Werkstück aus der Pressenstufe 24 mit einem Transferschritt S, der dem Pressenstufenabstand a entspricht, in das Werkzeug der Pressenstufe 25 schafft, arbeiten die Sauger 31, 32 mit der Ablagestufe 37 zusammen. Auch diese Sauger durchlaufen aber den einheitlichen Transferschritt S, der für alle Sauger gilt.While in the transfer process the sucker 33, the workpiece from the press stage 24 with a transfer step S corresponding to the press stage distance a, creates in the tool of the press stage 25, the suckers 31, 32 cooperate with the storage stage 37. But these suckers also go through the uniform transfer step S, which applies to all suckers.
Um das Werkstück von dem Sauger 31 zu übernehmen, fährt die Aufnahme 38 zunächst in die in
Wie ersichtlich ermöglicht es das erfindungsgemäße Konzept der aktiv bewegten Zwischenablage einen vorhandenen unterschiedlichen Stationsabstand bzw. Pressenstufenabstand auszugleichen. Dazu wird im Bereich zwischen den Pressenstößeln 9, 10 und zwischen Pressenständern 6 eine aktive Zwischenablage 37 vorgesehen. Die Transfereinrichtung 28 transportiert das Blechteil von der letzten Umformstation 23 des ersten Pressenstößels 9 auf die Zwischenablage 37. Die aktive Zwischenablage transportiert das Teil in Durchlaufrichtung soweit, dass es von der Transfereinrichtung 28 in die erste Umformstation 24 des nächsten Pressenstößels 10 gelegt werden kann. Die aktive Zwischenablage 37 führt mit dem Werkstück einen programmierbaren Weg in Durchlaufrichtung aus und ermöglicht die Anwendung konstanter und gleicher Transferschritte S bei unterschiedlichen Pressenstufenabständen, die kein ganzzahliges Vielfaches des Transferschritts S sind.As can be seen, the inventive concept of actively moving the clipboard makes it possible to compensate for an existing different station spacing or press stage spacing. For this purpose, an active clipboard 37 is provided in the area between the press rams 9, 10 and between press stands 6. The transfer device 28 transports the sheet metal part from the last forming station 23 of the first press ram 9 onto the clipboard 37. The active clipboard transports the part in the direction of passage so far that it can be laid by the transfer device 28 into the first forming station 24 of the
