Abstract

The transfer device makes possible different motional sequences of the holding means (40) for the sheet-metal parts to be moved through the metal-forming machine tool. The holding means are secured on travelling carriages (24, 25). The travelling carriages (24, 25) are cam-guided, travelling carriage (25) performing a transfer motion (82) out of a processing stage (86) into an idle stage (88), taking a sheet-metal part along with it. The return motion (84) is interrupted in an intermediate position (89) during the forming process performed on the sheet-metal parts. Travelling carriage (24) executes a transfer motion (83) out of the idle stage (88) into a processing stage (87) and a return motion (85) interrupted temporarily in an intermediate stage (89). The perpendicularly guided motion components of the cams (82, 83, 84, 85) serve for the take-up and deposition of sheet-metal parts in processing stages, the extended lowering motion (94) serving for the deposition of the holding means onto sliding tables which can be moved into the press. The low-mass construction using travelling carriages (24, 25) makes possible high accelerations in the motions. The use of intermediate deposition points (17) in the idle stages (88) considerably shortens the transfer motions. <IMAGE>

Description

Die Erfindung betrifft eine Umsetzeinrichtung in einer Transfer­presse o.dgl. Umformmaschine.The invention relates to a transfer device or the like in a transfer press. Forming machine.

Transferpressen, Großteilstufenpressen, Pressen-Anlagen sind Um­formmaschinen, in denen Blechteile durch Verfahrensschritte wie Zie­hen und Stanzen geformt werden. Die Pressen weisen hierfür zumindest einen Stößel auf, an dem ein Werkzeug oder Werkzeugsatz (Oberwerk­zeug) befestigt ist, das mit einem Werkzeug oder Werkzeugsatz (Unter­werkzeug) im Pressentisch oder auf einem Schiebetisch zusammenwirkt. Die Stößel sind über Antriebsmittel der Presse auf- und abbewegbar. In Bereichen zwischen den Ständern zu nachgeordneten Pressen, den sog. Leerstufen, sind Zwischenablagen angebracht. Das Wechseln der Werkzeuge bzw. Werkzeugsätze erfolgt vermittels Schiebetischen, die aus der Presse hierfür herausfahrbar sind.Transfer presses, large section presses, press systems are forming machines in which sheet metal parts are formed by process steps such as drawing and punching. For this purpose, the presses have at least one ram to which a tool or tool set (upper tool) is fastened, which interacts with a tool or tool set (lower tool) in the press table or on a sliding table. The plungers can be moved up and down via drive means of the press. In the areas between the stands to downstream presses, the so-called empty stages, clipboards are attached. The tools or tool sets are changed using sliding tables that can be moved out of the press for this purpose.

In der US-PS 4 625 540 ist eine solche Presse beschrieben worden mit einer Einrichtung zum Umsetzen der Blechteile in den Bearbeitungs­stufen. Diese Umsetzeinrichtung weist zwei Laufschienen beiderseits von Stößel und Werkzeugen und in Richtung des Blechteiletransports sich erstreckend auf. Die Laufschienen sind vermittels Stützen auf dem Pressenbett abgestützt. Es sind weiterhin je Laufschiene eine Platte vorgesehen mit Laufrollen zur Auflage auf den Laufschienen. Beide Platten sind durch eine Strebe miteinander verbunden. An der Strebe sind zwei Transferstangen gelagert, die sich parallel zu den Laufschienen erstrecken. Die Transferstangen sind mit einem Kurvenfol­gerhebel verbunden, der seine Schwingbewegung von einer Steuerkurve erhält. Die Steuerkurve ist antriebsseitig mit dem Hauptantrieb der Presse wirkverbunden. Die Transferstangen sind durch Querstreben starr miteinander verbunden. In Führungen der Transferstangen sind Querbalken über einen zusätzlichen Antrieb relativ zu den Transfer­stangen beweglich gelagert. An den Querbalken sind Vakuumsauger ange­bracht, die durch die Bewegung der Querbalken auf die Länge der Blech­teile einstellbar sind. Für die Umformphase sind die Querbalken mit den Vakuumsaugern in Bereiche außerhalb von Stößel und Werkzeugen ver­stellbar. Die Transferstangen sind durch nicht näher dargestellte oder erläuterte Hebemittel anhebbar und absenkbar. Das Einrichten der Vakuumsauger auf die veränderte Größe neuer Blechteile beim Umrüsten der Presse muß von Hand erfolgen ohne die Möglichkeiten des Einrich­tens vorab während des Pressenlaufes.Such a press has been described in US Pat. No. 4,625,540 with a device for converting the sheet metal parts in the processing stages. This transfer device has two running rails on both sides of the plunger and tools and extending in the direction of the sheet metal parts transport. The rails are supported on the press bed by means of supports. There is also a plate for each track with rollers to rest on the tracks. Both plates are connected to each other by a strut. Two transfer rods are mounted on the strut, which extend parallel to the running rails. The transfer rods are connected to a cam follower lever, which oscillates from a control cam receives. The control cam is operatively connected to the main drive of the press on the drive side. The transfer rods are rigidly connected to each other by cross struts. Crossbars are movably supported in guides of the transfer rods via an additional drive relative to the transfer rods. Vacuum cups are attached to the crossbeams and can be adjusted to the length of the sheet metal parts by moving the crossbeams. For the forming phase, the crossbeams with the vacuum cups can be adjusted in areas outside of the ram and tools. The transfer rods can be raised and lowered by lifting means, not shown or explained. Setting up the vacuum cups to the changed size of new sheet metal parts when converting the press must be done by hand without the possibility of setting up in advance during the press run.

Es ist eine Aufgabe der Erfindung, eine Umsetzeinrichtung zu schaffen, die den Wechselvorgang der Haltemittel für Blechteile ande­rer Größe gestattet. Im besonderen soll der Wechselvorgang der Halte­mittel automatisch und zugleich mit dem Wechsel der Werkzeuge vermit­tels Schiebetisch erfolgen. Die Wechselstellung der Haltemittel bzw. der diese tragenden Mittel soll unabhängig von dem Antrieb für die Transferbewegungen der Blechteile erreicht werden.It is an object of the invention to provide a transfer device which allows the changing process of the holding means for sheet metal parts of other sizes. In particular, the changing process of the holding means should take place automatically and at the same time as the tools are changed by means of a sliding table. The changing position of the holding means or the means carrying these should be achieved independently of the drive for the transfer movements of the sheet metal parts.

Die Aufgabe ist gelöst durch die gegenständlichen Merkmale nach dem Anspruch 1. Die weiteren Ansprüche stellen bevorzugte und für sich erfinderische Ausgestaltungen dar.The object is achieved by the objective features according to claim 1. The further claims represent preferred and inventive configurations.

Hierbei ist der massearme Aufbau von Vorteil. Die Antriebsmittel und die die Bewegungen übertragenden und umlenkenden Mittel der Um­setzeinrichtung sind dem Bereich (Kopfbereich) der Presse bzw. den Pressen zugeordnet, in dem auch die Antriebsmittel für den bzw. die Stößel untergebracht sind. Die Umsetzeinrichtung ist sowohl in Pres­senstraßen als auch in Kompaktpressen nachrüstbar. Weiterhin erfin­dungswesentlich sind die kurzen Umsetzbewegungen der Laufwagen und de­ren zwischenzeitliche Wartestellung außerhalb der Bearbeitungsstufen während der Umformphasen.The low-mass structure is an advantage here. The drive means and the movement transmitting and deflecting means of the transfer device are assigned to the area (head area) of the press or the presses, in which the drive means for the plunger (s) are also accommodated. The transfer device can be retrofitted in both press lines and compact presses. Also essential to the invention are the short transfer movements of the carriages and their temporary waiting position outside the processing stages during the forming phases.

In besonders vorteilhafter Weise ist die Umsetzeinrichtung nach der Erfindung in neuartigen Hybrid-Pressen-Anlegen einsetzbar mit zwischen zwei Bearbeitungsstufen (Leerstufen) eingerichteten Zwischen­ablagen, da die Wagen paarweise bei entsprechender Auslegung des An­ triebs unterschiedliche Bewegungen ausführen können. Die Sandwichbau­weise insbesondere von Laufwagen und Quertraversen ermöglicht nicht nur eine schnellstmögliche Anpassung an neue Blechteilgrößen und ande­re -formen; die Sandwichbauweise erlaubt darüberhinaus den einfachen Ausbau und die Erneuerung von Bauteilen und Baugruppen.In a particularly advantageous manner, the transfer device according to the invention can be used in new types of hybrid presses with intermediate shelves arranged between two processing stages (empty stages), since the carriages are paired with a suitable design of the operator drive can perform different movements. The sandwich construction, in particular of carriages and cross members, not only enables the fastest possible adaptation to new sheet metal part sizes and other shapes; the sandwich construction also allows for easy removal and renewal of components and assemblies.

Anhand eines vorteilhaften und bevorzugten Ausführungsbeispiels soll im folgenden die Erfindung näher erläutert werden.Based on an advantageous and preferred embodiment, the invention will be explained in more detail below.

Haltemittel angeordnet zum Er­fassen und Fördern der Blechteile 33 durch die Hybrid-Pressen-Anlage. Die Transportgestänge 36, 37 können ggf. beiderseits zu den Laufschie­nen 18, Fig. 2, oder einseitig zu den Laufschienen angeordnet sein.The in Figs. 1, 2 and 3, the conversion device 5 initially has two running rails 18, one of which runs behind the plungers 6 with the tool upper parts 14, viewed in FIG. 1, the second running rail in front of the plungers 6 with the tool upper parts 14 in the longitudinal direction of the shown Hybrid press system is arranged extending. The running rails 18 can be raised and lowered by means of adjusting means such as air cylinders or the like, or as shown, by means of deflection gears 19 (double arrow 20). The deflecting gear 19 are still in detail to FIGS. 5 and 6. The deflection gear 19 on the rear side of the stator and that on the front side of the stator are each connected by a lifting linkage 21 with a cam follower lever 46 on each side of the stator of a cam disk arrangement positioned overall at 41 in articulation points 22. As shown in Figs. 1 and 2 indicated and shown in FIGS. 3 and 4, carriages 23 to 31 are located on each of the rails 18. The carriages 23, 25, 27, 29 and 31 are by a linkage 37 and with a cam follower 47 connected. The carriages 24, 26, 28 and 30 are connected to one another and to a cam follower lever 48 by a transport linkage 36. The carriages 23 to 31 located opposite one another on the spaced running rails 18 are connected to one another by cross members 34. On the cross members 34 suction cups 40 or the like. Holding means arranged for gripping and conveying the sheet metal parts 33 through the hybrid press system. The transport rods 36, 37 can optionally be arranged on both sides of the running rails 18, FIG. 2, or on one side to the running rails.

Die Kurvenscheibenanordnung 41 umfaßt, wie es die Fign. 2 und 3 näher erkennen lassen, eine Kurvenscheibenwelle 42. Die Kurvenschei­benwelle 42 wird von der Hauptwelle 39 über Umlenk- bzw. Umsetzgetrie­be gedreht. Diese bei Umformmaschinen bekannten Mittel sind nicht ge­zeigt worden. Auf der Kurvenscheibenwelle 42 sind je Ständerseite ei­ne Kurvenscheibe 44 für die Bewegung eines der beiden Kurvenfolgerhe­bel 46, eine Kurvenscheibe 45 für die Bewegung eines der beiden Kur­venfolgerhebel 47 und eine Kurvenscheibe 43 für die Bewegung eines der beiden Kurvenfolgerhebel 48 drehfest angeordnet. Die Kurvenschei­ben 44, 43, 45 können Doppelkurvenscheiben sein zur Erzeugung eines Zwanglaufes in den Bewegungen Heben und Senken der Laufschienen 18 und der Transferbewegungen der Laufwagen 23 bis 31.The cam disk arrangement 41 comprises, as shown in FIGS. 2 and 3 can be seen in more detail, a camshaft shaft 42. The camshaft shaft 42 is rotated by the main shaft 39 via a deflection or conversion gear. These means known in metal forming machines have not been shown. On the cam shaft 42, a cam plate 44 for the movement of one of the two cam follower levers 46, a cam plate 45 for the movement of one of the two cam follower levers 47 and a cam disc 43 for the movement of one of the two cam follower levers 48 are arranged in a rotationally fixed manner on each stator side. The cam disks 44, 43, 45 can be double cam disks for generating a forced run in the movements of lifting and lowering the running rails 18 and the transfer movements of the carriages 23 to 31.

Entsprechend Fig. 3 ist jedes der Hebegestänge 21 in seiner Aus­gangslage durch eine Absenkbewegung, 94 in Fig. 4, eines Stelltriebes veränderbar, um so eine weitere abgesenkte Stellung durch eine Bewe­gung 94, in Fig. 4, für die Laufschienen 18 zu erreichen, die von den Kurvenscheiben 44 nicht vorgebbar ist. Diese abgesenkte Stellung ist für die Ablage der Quertraversen 34 auf den Stützen 35 der Schiebe­tische 13 bei Werkzeugwechsel und Wechsel der Haltemittel 40 erforder­lich. Jeder Stelltrieb weist hierfür einen Stellmotor 51 auf, der ei­ne Spindel 52 treibt. Die Drehbewegung der Spindel 52 wird über eine Zahnradpaarung 53 auf eine zweite Spindel 49 übertragen. In der Lasche 54 ist ein Bewegungsgewinde (Mutter) eingebracht, das mit der Spindel 49 zusammenwirkt und so bei der Drehung der Spindel 49 eine Veränderung der Länge des Hebegestänges 21 verursacht. Die Kurven­scheiben 45, 43 für die Bewegung der Laufwagen 23 bis 31 sind derart in ihren von den Kurvenfolgerhebeln 47, 48 abgegriffenen Kurvenbahnen ausgelegt, daß der erste Laufwagen 23 und jeder übernächste Laufwagen 25, 27, 29, 31 entsprechend Fig. 4 eine Umsetzbewegung 82 ausführt von einer Bearbeitungsstufe 86 in eine Leerstufe 88 mit der Zwischen­ablage 17 und eine in einer Zwischenstellung 89 zwischen Bearbeitungs­stufe 86 und Leerstufe 88 für die Zeit der Umformung unterbrochene Rückbewegung 84 in die Bearbeitungsstufe 86.According to FIG. 3, each of the lifting rods 21 can be changed in its starting position by a lowering movement, 94 in FIG. 4, of an actuator, so as to achieve a further lowered position by a movement 94, in FIG. 4, for the running rails 18 which cannot be specified by the cam disks 44. This lowered position is necessary for the storage of the cross members 34 on the supports 35 of the sliding tables 13 when changing tools and changing the holding means 40. For this purpose, each actuator has a servomotor 51 which drives a spindle 52. The rotational movement of the spindle 52 is transmitted to a second spindle 49 via a gear pair 53. A movement thread (nut) is introduced into the tab 54, which interacts with the spindle 49 and thus causes a change in the length of the lifting rod 21 when the spindle 49 rotates. The cam disks 45, 43 for the movement of the carriages 23 to 31 are designed in their cam tracks tapped by the cam follower levers 47, 48 in such a way that the first carriage 23 and each next carriage 25, 27, 29, 31 as shown in FIG. 4 have a transfer movement 82 executes from a processing stage 86 into an empty stage 88 with the clipboard 17 and a return movement 84 interrupted in an intermediate position 89 between the processing stage 86 and the empty stage 88 for the time of the forming into the processing stage 86.

Der zweite Laufwagen 24 und jeder der mit diesem verbundene über­nächste Laufwagen 26, 28, 30 führt gleichzeitig eine Umsetzbewegung 83 aus von einer Leerstufe 88 mit der Zwischenablage 17 in eine Bear­ beitungsstation 87 und eine in einer Zwischenstellung 89 zwischen Leerstufe 88 und Bearbeitungsstufe 87 für die Umformung zwischenzeit­lich unterbrochene Rückbewegung 85 in die Leerstufe 88 aus. Die Bear­beitungsstufen sind charakterisiert durch die Werkzeuge 14, 15. Die senkrecht geführten Bewegungsanteile an den in Fig. 4 gezeigten Kur­ven 82, 83, 84, 85 werden vermittels der synchron zu den Kurvenschei­ben 43, 45 bewegten Kurvenscheiben 44 bewirkt.The second carriage 24 and each of the carriages 26, 28, 30 next but one connected to it at the same time carry out a transfer movement 83 from an empty stage 88 with the clipboard 17 into a bear processing station 87 and an intermediate position 89 between empty stage 88 and processing stage 87 for the return movement 85 interrupted in the meantime into the empty stage 88. The machining stages are characterized by the tools 14, 15. The vertically guided movement components on the curves 82, 83, 84, 85 shown in FIG. 4 are brought about by means of the cam discs 44 moved synchronously with the cam discs 43, 45.

Der in Fig. 5 gezeigte Schnitt, und teilweise auch der in Fig. 6 gezeigte Schnitt, läßt den Bereich eines der Ständer 12 erkennen mit einem Umlenkgetriebe 19. Das Hebegestänge 21 verläuft in Fig. 5 senk­recht zur Zeichenebene. Die Bewegung des Hebegestänges 21 wird vermit­tels Verzahnung und Eingriff mit einem Stirnrad 56 und einer Drehwel­le 57 auf ein zweites Stirnrad 58 übertragen. Das zweite Stirnrad 58 wirkt mit einer Zahnstange 59 zusammen. Die Endbereiche der Zahn­stange 59 sind mit einer oberen Bundbuchse 61 und einer unteren Bund­buchse 62 fest verbunden. Die obere Bundbuchse 61 bildet eine Lauf­fläche 65 für ein Heberohr 64. Die obere Bundbuchse 61 wirkt weiter­hin mit einer Deckelplatte 63 zusammen, die auf einen oberen Bund des Heberohres 64 geschraubt ist. Diese Verbindung ermöglicht eine Dre­hung des Heberohres 64. Die Drehung des Heberohres 64 wird durch ein Stellmittel 76, beispielsweise einen Druckzylinder bewirkt, der über einen Lagerbock 77 gestellfest angebracht ist. Der Lagerbock 77 ermög­licht eine Schwenkbewegung des Stellmittels 76. Das Stellmittel 76 ist bei 78 an einer Ringbuchse 75 angelenkt. Die Ringbuchse 75 greift z.B. über Führungsbolzen in Längsnutungen 90 des Heberohres 64 ein, um einerseits so die für die Laufschienen 18 erforderliche Hebe Senkbewegung 20 des Heberohres 64 zu ermöglichen und um andererseits die Drehung des Heberohres 64 zu bewirken.The section shown in FIG. 5, and partly also the section shown in FIG. 6, shows the area of one of the stands 12 with a deflecting gear 19. The lifting linkage 21 in FIG. 5 runs perpendicular to the plane of the drawing. The movement of the lifting rod 21 is transmitted to a second spur gear 58 by means of teeth and engagement with a spur gear 56 and a rotary shaft 57. The second spur gear 58 interacts with a rack 59. The end regions of the toothed rack 59 are firmly connected to an upper flange bushing 61 and a lower flange bushing 62. The upper collar bushing 61 forms a running surface 65 for a lifting tube 64. The upper collar bushing 61 also interacts with a cover plate 63 which is screwed onto an upper collar of the lifting tube 64. This connection enables the lifting tube 64 to be rotated. The rotation of the lifting tube 64 is brought about by an adjusting means 76, for example a pressure cylinder, which is attached to the frame via a bearing block 77. The bearing block 77 enables the adjusting means 76 to pivot. The adjusting means 76 is articulated at 78 on an annular bushing 75. The ring bushing 75 engages e.g. via guide bolts in longitudinal grooves 90 of the lifting tube 64 in order to enable the lifting and lowering movement 20 of the lifting tube 64 required for the running rails 18 on the one hand and to effect the rotation of the lifting tube 64 on the other hand.

Das Heberohr 64 trägt an dem unteren Endteil einen Flansch 66 mit einer Flanschbuchse 67. Die Flanschbuchse 67 ist von einer Lagerbuch­se 73 und einer Tragbuchse 72 umgehen zur Bildung eines Drehlagers zwischen Heberohr 64 und einem Träger 71. Die Tragbuchse 72 ist in dem Träger 71 mittels Verschraubung 74 gehalten. Auf das untere Ende der Tragbuchse 72 ist eine Bundbuchse 68 gesetzt. Durch die Bund­buchse 68 ist ein Schraubmittel 69 hindurchgeführt, um so den Träger 71 an dem Heberohr 64 zu befestigen. Mit dem Träger 71 ist die Lauf­ schiene 18 starr verbunden. Die Laufschiene 18 weist zwei Schienen bzw. Schienenpaare 79 auf, auf denen Rollen 80 der Laufwagen 23 bis 31, hier die Rollen 80 des Laufwagens 25, rollen. Mit 37 ist das an das Gehäuse des Laufwagens 25 angeschlossene Transportgestänge bezif­fert. Durch die Drehbewegung des Heberohres 64 vermittels Stellmittel 76 ist eine Verstellung der Laufschienen 18 von innen nach außen, Pfeil 91, zum z.B. Entkuppeln der Quertraversen 34 von den Laufwagen 25 möglich bzw. von außen nach innen, Pfeil 92, dementsprechend zum Kuppeln.The lifting tube 64 carries a flange 66 with a flange bushing 67 at the lower end part. The flange bushing 67 is bypassed by a bearing bushing 73 and a support bushing 72 to form a pivot bearing between the lifting tube 64 and a carrier 71. The carrier bushing 72 is in the carrier 71 by means of Screw connection 74 held. A collar bushing 68 is placed on the lower end of the support bushing 72. A screw 69 is passed through the collar bushing 68 in order to fasten the carrier 71 to the lifting tube 64. With the carrier 71 is the barrel rail 18 rigidly connected. The running rail 18 has two rails or pairs of rails 79, on which rollers 80 of the carriages 23 to 31, here the rollers 80 of the carriage 25, roll. The transport linkage connected to the housing of the carriage 25 is numbered 37. The rotary movement of the lifting tube 64 by means of adjusting means 76 enables the rails 18 to be adjusted from the inside to the outside, arrow 91, for example for uncoupling the cross members 34 from the carriage 25 or from the outside inwards, arrow 92, accordingly for coupling.

Die Fig. 6 zeigt darüberhinaus die vermittels Stellmittel 76 be­wirkten Stellungen 64′ für die Betriebsstellung und 64˝ für die Ent­kuppelstellung bzw. Kuppelstellung für die Quertraversen 34. Mit 93 sind Kupplungsbereiche bzw. Kupplungen angedeutet für das Lö­sen der Querstreben 34 von den Laufwagen, hier den Laufwagen 24, 25 bzw. zum Kuppeln an diese infolge einer Bewegung der Laufschienen 18 in einer der Richtungen der Pfeile 91, 92. In Betriebsstellung befin­den sich die Schienen 79 an den Laufschienen 18 mittig zu dem Hebe­rohr 64.Fig. 6 also shows the position 64 'by means of actuating means 76' for the operating position and 64˝ for the uncoupling position or coupling position for the cross members 34. With 93 coupling areas or couplings are indicated for releasing the cross struts 34 from the carriage, here the carriages 24, 25 or for coupling to them as a result of a movement of the running rails 18 in one of the directions of the arrows 91, 92. In the operating position, the rails 79 are located on the running rails 18 in the center of the lifting tube 64.
