Definitions
- the invention relates to a transfer press with workpieces converting gripper rails in the processing stages of the type specified in the preamble of claim 1.
- a generic transfer press is known from DE-A-23 59 912.
- gripper-equipped rails that convey the workpieces from the input station to the first processing stage, between the processing stages and from the last processing stage to an output area.
- the gripper rails are driven in at least two axes - moving the workpieces and opening them to grasp and release the workpieces in a synchronous movement.
- the tools required for punching, shaping and trimming are generally installed aligned with the longitudinal center of the transfer press. Often, the center of gravity of the workpieces is not centered on the tool and therefore not on the longitudinal center of the transfer press, and because of the shape of the workpieces the gripping tongs on the workpieces are often not symmetrical to the longitudinal center of the transfer press.
- the gripper rails are then loaded unevenly. One gripper rail is to be equipped with longer gripping tools, the other gripper rail is to be equipped with shorter gripping tools.
- the press described in DE-A-31 03 046 has a drive system for adjusting pick-up in the articulation points of the gripper rails in the area of the stands, comprising an adjusting motor with a coupling, connecting shafts and Bevel gear.
- the gripper rails articulated in the articulation points for the closing-open movement are mounted in a longitudinally displaceable manner on support elements which can be moved in the manner of a slide; the support elements can be driven transversely with the plunger movement via a rack and pinion drive.
- a spindle is introduced, the position of the gripper rails relative to one another in the sense of a larger or smaller starting width being adjustable by the adjusting motor.
- Changing the initial width of the gripper rails is only possible by simultaneously adjusting both gripper rails to the new workpiece dimensions.
- the one-sided attack of the adjusting means for changing the initial width of the gripper rails requires larger protrusions of the press structure in the case of larger changes in width, for example greater than 400 mm, since the spindle must be supported and thus must be guided over the length of the adjustment dimension.
- a transfer press is known with gripper rails for transferring workpieces from processing stage to processing stage.
- the gripper rails are mounted in brackets that have support elements and guide elements for the transfer movements.
- the movements of the gripper rails in and against the transfer direction and in the closing-open directions take place in time with the ram movement.
- an adjusting device is provided with a nut-spindle connection that can be acted upon by a motor via a gear mechanism.
- the object of the invention is to provide a device for changing the initial width of the gripper rails, which is independent of the drive for the closing-open movement, which allows the individual setting of the starting position of each gripper rail and which uses the space between the gripper rails.
- a particular advantage of the invention can be seen in the intermediate member designed as a bearing bush between the support element and the lead screw, which adjusts the initial width of the gripper rails by a cam part and one or more cam followers between the bearing bush and the lead screw or also between the bearing bush and the support element.
- the multi-part mounting of the lead screw in the support element by means of the bearing bush ensures high adjustment accuracy with a long service life.
- Claim 2 characterizes a first preferred embodiment according to the invention.
- Claim 3 characterizes a further embodiment according to the invention with a curve follower part introduced between the support element and the curve part designed as a lead screw.
- this embodiment of the invention also enables further development within the meaning of claim 4.
- the features according to claim 4 characterize the possibility of a separate change in the starting position of the gripper rails by different adjustment dimensions.
- each gripper rail 1 is supported in each of its articulation areas, area of each console 2, via a respective support element 3, in this by means of guide means 4 in the direction of movement of the workpieces, a direction perpendicular to the plane of the drawing, adjustable by a press-side transfer drive (not shown) and by means of the support element 3 and roller guides, rollers 6, on the support elements 3 and rails 7 on the console 2, in the indicated by an arrow 8 Closing-opening directions movable.
- the movement drive of the gripper rails 1 in the closing-opening directions 8 takes place from a press-driven, for example up and down movable drive rod 9 via rotatable in the bracket 2 angular lever 11, one tab 12 and one in each rail 7 in the Closing-opening directions 8 slidably mounted, roller-guided carriage 13.
- a coupling rod 19 is arranged for the synchronous opposite movement of the gripper rails 1 in the closing-opening directions 8.
- a lead screw 14 is rotatably mounted, which is guided into the area of the associated support element 3 and is mounted in a central bore of the support element 3 via a bearing bush 16 or directly in the support element 3.
- the lead screw 14 can be provided with a thread-like guide groove, in which, as shown, in the bearing bush 16 or in the support element 3, rotatably mounted balls or rollers 17 are guided to take the support element 3 with the movement of the drive means from drive rod 9, angle lever 11 , Tab 12 and slide 13 in the closing-opening directions 8.
- the relative position of each support element 3 to the lead screw 14 for changing the starting position of the gripper rails 1 can, as shown, by rotating the bearing bush 16 in the support element 3 or in the event of failure the bearing bush 16 in a second embodiment by rotating the lead screw 14 with a corresponding rotary bearing of this in the carriage 13.
- Lead screw 14 and balls or rollers 17 are mentioned as examples.
- curve part 14 and curve follower part 17 are conceivable, in which, for example, the bearing bush 16 is rotatable on the lead screw 14, but is not axially displaceable and is provided with a curve part, for example a spiral guide groove, which has a curve follower part, e.g. . a pin in the support element 3 cooperates.
- the rotation of the bearing bush 16 or a rotatable lead screw 14 according to the second embodiment mentioned takes place via a gear 21 formed or attached to the end regions thereof, and a second gear 22 which is rotatably mounted in the support element 3 and which engages in the gear 21 the console 2 rotatably supported longitudinally profiled shaft 23, which is guided through an identical profile of the inner bore 20 in the gear 22, the longitudinally profiled shaft 23 extending over the entire adjustment range of the support element 3 extends.
- the longitudinally profiled shaft 23 is operatively connected via shafts or cardan shafts 24 and angular gear 26 to a servomotor 27, FIG. 1, common to all longitudinally profiled shafts 23. Additional angular gears 28 are assigned to the individual articulation areas of the gripper rail closing-opening movements.
- Fig. 2 sees, in contrast to Fig. 1, a separate drive each gripper rail 1, 1 'in front of each with an actuator 27, 27' and angular gear 28, 28 'and shafts or cardan shafts 24, 24' in double number, whereby each gripper rail 1, 1 'with appropriate control of the respective servo motor 27, 27' individually (separately) for a change in the basic width taking into account, for example the center of gravity of the workpieces is articulated.

Description
Die Erfindung betrifft eine Transferpresse mit Werkstücke in den Bearbeitungsstufen umsetzenden Greiferschienen der in Oberbegriff des Anspruchs 1 angegebenen Art. Eine gattungsgemäße Transferpresse ist aus der DE-A-23 59 912 bekannt.The invention relates to a transfer press with workpieces converting gripper rails in the processing stages of the type specified in the preamble of
In Transferpressen sind greiferbestückte Schienen vorhanden, die die Werkstücke aus der Eingabestation in die erste Bearbeitungsstufe, zwischen den Bearbeitungsstufen und aus der letzten Bearbeitungsstufe in einen Ausgabebereich fördern. Die Greiferschienen sind in zumindest zwei Achsen - Umsetzen der Werkstücke und Schließen-öffnen zum Erfassen und Freigeben der Werkstücke in zueinander synchroner Bewegung anzutreiben.In transfer presses there are gripper-equipped rails that convey the workpieces from the input station to the first processing stage, between the processing stages and from the last processing stage to an output area. The gripper rails are driven in at least two axes - moving the workpieces and opening them to grasp and release the workpieces in a synchronous movement.
Die für das Stanzen, Formen und Beschneiden erforderlichen Werkzeuge werden im allgemeinen zur Längsmitte der Transferpresse ausgerichtet eingebaut. Oftmals liegt der Masseschwerpunkt der Werkstücke nicht mittig zum Werkzeug und somit nicht auf der Längsmitte der Transferpresse und es befinden sich zudem die Angriffspunkte der Greifzangen an den Werkstücken wegen der Form der Werkstücke oftmals nicht symmetrisch zur Längsmitte der Transferpresse. Die Greiferschienen werden dann ungleichmäßig beansprucht. Die eine Greiferschiene ist mit längeren Greifzeugen, die andere Greiferschiene ist mit kürzeren Greifzeugen zu bestücken.The tools required for punching, shaping and trimming are generally installed aligned with the longitudinal center of the transfer press. Often, the center of gravity of the workpieces is not centered on the tool and therefore not on the longitudinal center of the transfer press, and because of the shape of the workpieces the gripping tongs on the workpieces are often not symmetrical to the longitudinal center of the transfer press. The gripper rails are then loaded unevenly. One gripper rail is to be equipped with longer gripping tools, the other gripper rail is to be equipped with shorter gripping tools.
Zur Anpassung der Hublage (Änderung der Ausgangsweite) an andere Werkstückabmessungen nach einem Werkzeugwechsel weist die in der DE-A-31 03 046 beschriebene Presse zum Verstellabgriff in den Anlenkpunkten der Greiferschienen in Bereich der Ständer ein Antriebssystem auf aus einem Verstellmotor mit einer Kupplung, Verbindungswellen und Kegelradgetrieben. Die in den Anlenkpunkten für die Schließ-öffnen-Bewegung angelenkten Greiferschienen sind auf schlittenartig bewegbaren Tragelementen längsverschieblich gelagert; die Tragelemente sind mit der Stößelbewegung über einen Zahnstangen-Ritzel-Antrieb quer dazu antreibbar. In dem gemeinsamen Anlenkpunkt von Stößel und Verstellmotor ist eine Spindel eingebracht, bei deren Verstellung durch den Verstellmotor die Lage der Greiferschienen zueinander im Sinne einer größeren oder geringeren Ausgangsweite einstellbar ist. Die Änderung der Ausgangsweite der Greiferschienen ist nur durch gleichzeitiges Verstellen beider Greiferschienen an die neuen Werkstückabmessungen möglich. Der einseitige Angriff der Einstellmittel zur Änderung der Ausgangsweite der Greiferschienen erfordert bei größeren Weitenänderungen, z.B. größer 400 mm, eine seitlich überstehende Ausladung des Pressenaufbaues, da die Spindel gelagert und somit über die Länge des Verstellmaßes geführt werden muß.In order to adapt the stroke position (change in the initial width) to other workpiece dimensions after a tool change, the press described in DE-A-31 03 046 has a drive system for adjusting pick-up in the articulation points of the gripper rails in the area of the stands, comprising an adjusting motor with a coupling, connecting shafts and Bevel gear. The gripper rails articulated in the articulation points for the closing-open movement are mounted in a longitudinally displaceable manner on support elements which can be moved in the manner of a slide; the support elements can be driven transversely with the plunger movement via a rack and pinion drive. In the common pivot point of the plunger and adjusting motor, a spindle is introduced, the position of the gripper rails relative to one another in the sense of a larger or smaller starting width being adjustable by the adjusting motor. Changing the initial width of the gripper rails is only possible by simultaneously adjusting both gripper rails to the new workpiece dimensions. The one-sided attack of the adjusting means for changing the initial width of the gripper rails requires larger protrusions of the press structure in the case of larger changes in width, for example greater than 400 mm, since the spindle must be supported and thus must be guided over the length of the adjustment dimension.

Die Greiferschienen sind in Konsolen gelagert, die Tragelemente und Führungselemente für die Umsetzbewegungen aufweisen. Die Bewegungen der Greiferschienen in und entgegen der Umsetzrichtung sowie in den Schließ-öffnen-Richtungen erfolgt im Takt der Stößelbewegung. Für eine Änderung der Ausgangsweite der Greiferschienen in der Schließ-öffnen-Bewegung ist eine Einstellvorrichtung vorgesehen mit einer von einem Motor über Getriebemittel beaufschlagbaren Muttern-Spindel-Verbindung.From DE-A-23 59 912 a transfer press is known with gripper rails for transferring workpieces from processing stage to processing stage. The gripper rails are mounted in brackets that have support elements and guide elements for the transfer movements. The movements of the gripper rails in and against the transfer direction and in the closing-open directions take place in time with the ram movement. To change the initial width of the gripper rails in the closing-open movement, an adjusting device is provided with a nut-spindle connection that can be acted upon by a motor via a gear mechanism.
Die Aufgabe der Erfindung liegt in der Schaffung einer Vorrichtung zur Änderung der Ausgangsweite der Greiferschienen, die vom Antrieb für die Schließ-Öffnen-Bewegung unabhängig ist, die die Einzeleinstellung der Ausgangslage jeder Greiferschiene zuläßt und die den Freiraum zwischen den Greiferschienen nutzt.The object of the invention is to provide a device for changing the initial width of the gripper rails, which is independent of the drive for the closing-open movement, which allows the individual setting of the starting position of each gripper rail and which uses the space between the gripper rails.
