Die Presse 1 in Fig. 1 kann eine Einzelpresse oder eine durch
(Folge-)Pressen 51 zu einer Pressenanlage, Kompaktpresse, Hybridpresse
erweiterte Umformanlage sein. Die Presse 1 weist ein Kopfstück 7 auf
mit dem Pressenantrieb für den oder die Stößel 2 (Fig. 2). Mit 4 sind
Pressenständer positioniert, die auf dem Pressentisch 6 aufgesetzt
sind und auf denen das Kopfstück 7 aufgesetzt ist. In die Presse 1 ist
ein Schiebetisch 5 verfahrbar. Über diesen sind die Werkzeuge
austauschbar. Stößel 2 und Werkzeuge sind in Fig. 1 aus Gründen
besserer Erkennbarkeit der Umsetzeinrichtungen 8,9 nicht eingezeichnet.
Die Pressenständer 4 weisen je eine vertikal verlaufende Führung
18 auf, in der, wie es in Fig. 4 gezeigt ist, ein Führungswagen 41
heb- und senkbar verfahrbar ist. Jede der Umsetzeinrichtungen 8,9 umfaßt
weiterhin eine Führungsleiste 16, die den beiden linken bzw. hinteren
Pressenständern 4 zugeordnet ist und eine Führungsleiste 17, die
den beiden rechten bzw. vorderen Pressenständern 4 zugeordnet ist. Von

jeweils eine Zahnstange 24 befestigt, die parallel zu den vertikalen
Führungen 18 geführt ist. Die Führungsleisten 16,17 können einteilig
sein und sich so über die Gesamtlänge der Werkstückbewegung durch die
Presse 1 erstrecken. Bei Verwendung einer Umsetzeinrichtung 8,9 als
Einlegefeeder (Einlegegerät) oder als Entnahmefeeder (Entnahmegerät)
sind diese dem vorderen Einlegebereich bzw. dem hinteren Entnahmbereich
zugeordnet. Die Führungsleisten 16,17 können geteilt sein
und somit nur ein Transportmittel 25,26 aufnehmen. Die Führungsleisten
16,17 erstrecken sich über den gesamten Transportweg der Blechteile 3
in der Presse 1, bei Teilung über einen Teilweg. Jede der
Führungsleisten 16,17 weist eine horizontal verlaufende Längsführung
62 auf zur Führung von Haltemitteln 10,11 über Laufrollen 43. In jeder
der Führungsleisten 16,17 sind Umlenkrollen 27,28 drehbar gelagert,
von denen die Umlenkrolle 28 von einem Verstellmittel 29,31,33
(zweites Verstellmittel) drehgetrieben ist. Die Verstellmittel, die
insgesamt mit 13,14 positioniert sind, können Servomotoren 29,31,33
aufweisen, die über Getriebe 30,32,34 und die Umlenkrollen 28 um die
Umlenkrollen 27,28 herumgeführte Zahnriemen 25,26 oder derartige
Transportmittel in einer hin- und hergehenden, horizontalen Bewegung
antreiben. Die Haltemittel 10, 11 zum Umsetzen der Blechteile 3 in
Durchlaufrichtung 15 durch die Presse 1 können Aktivzangen, Passivzangen
oder wie gezeigt, magnet- oder saugerbestückte Quertraversen 10,
11 sein. Die Quertraversen 10, 11 sind über Mitnehmer 42 beidendig an
jeweils einem der Transportmittel 25,25 bzw. 26,26 befestigt.The

gleich positioniert. Fig. 2 zeigt eine Tragplatte 36, die pressenfest
angebracht ist und an der ein erstes Verstellmittel 19 zum Heben und
Senken der Führungsleisten 16, 17 und der mit diesen verbundenen Bauelemente
befestigt ist. Die Bewegung des z .B. als Servomotor ausgebildeten
ersten Verstellmittels 19 wird über ein Getriebe 21 auf eine horizontal
verlaufende Torsionswelle 22 übertragen, an deren beiden Enden
in die Zahnstangen 24 eingreifende und mit diesen zusammenwirkende
Zahnräder 23 starr befestigt sind.In Figs. 2 and 3 are the same parts as in FIGS. 1 and 4
positioned immediately. Fig. 2 shows a
Fig. 3 zeigt zwei pressenfeste Tragplatten 40 für je ein erstes
Verstellmittel 37, einem Servomotor, der über ein Getriebe 39 auf das
jeweils nächst zugeordnete Zahnrad 23 wirkt. Die Zahnräder 23 bzw. Getriebe
39 sind vermittels einer Torsionswelle 38 untereinander verbunden.
In gleicher Weise sind auch die Getriebe 30,32 bzw. die getriebenen
Umlenkrollen 28 in Fig. 1 durch eine Torsionswelle 20 untereinander
verbunden. Fig. 3 shows two press-fixed
Die Umsetzeinrichtungen 8, 9 in Fig. 1 sind hintereinander angeordnet,
so daß zwischen den Transportmitteln, Zahnriemen 25, 26 ein
Abstand vorhanden ist. Gemäß Fig. 5 befindet sich dieser Abstand zwischen
den einander zugewandten Umlenkrollen 27 der Zahnriemen 25 und
26. Zur Überbrückung dieses Abstands sind die Mitnehmer 42 zwischen
dem Befestigungsbereich 63 am Zahnriemen 25,26 und dem Befestigungsbereich
64 des Haltemittels 10,11 entsprechend lang gewählt. Der Mitnehmer
42 an dem Zahnriemen 25 und der Mitnehmer 42 an dem Zahnriemen 26
sind gegeneinander gerichtet.The
Die Umsetzbewegung der Blechteile 3 in Durchlaufrichtung 15 beginnt
mit der Entnahme eines Blechteils 3 aus einer Entnahmeposition
48, die eine Entstapelstation oder eine Orientierstation für das
Blechteil 3 sein kann oder aus einer Zwischenablage für das Blechteil
3, in einer Hebebewegung. Diese Hebebewegung wird durch die ersten
Verstellmittel 19,21 bzw. 37,39 erzeugt. Daran anschließend erfolgt
eine Umsetzbewegung 44 mit abschließender Absenkbewegung in die z .B.
Bearbeitungsposition 49, Orientierstation oder auf die Zwischenablage.
Die Umsetzbewegung 44 wird durch die zweiten Verstellmittel 13 erzeugt.
In gleicher Weise wird das in der Position 49 befindliche
Blechteil 3 durch eine Umsetzbewegung 45 in die Position 50 bewegt und
abgesandt. Diese Position 50 kann eine Bearbeitungsstation, eine
Zwischenablage, auch ein Förderband sein. Die Rücklaufbewegungen der
Haltemittel 10,11 sind mit 46,47 angedeutet.The conversion movement of the
Zum Ausrüsten einer Presse, einer Mehrständerpresse, in der Art
der Presse 1 und andeutungsweise Presse 51 mit weiteren (Folge-) Pressen
in Fig. 1, kann entsprechend Fign. 6 und 7 ein bisher verwendeter
Einlegefeeder durch eine Umsetzeinrichtung 52 in der zuvor beschriebenen
modulen Bauweise ersetzt werden. Die mit Magneten oder Saugnäpfen
bestückte Traverse 53 ist ggf. zur Überbrückung größerer Abstände,
z.B. zum Einlegen in die erste Bearbeitungsstufe 54 verlängert auszubilden.
Die Umsetzeinrichtungen 55 und 56 sind in der zuvor erläuterten
Bauweise ausgeführt. Durch die überlappende Anordnung der Transportmittel
25,26 infolge seitlichem Versatz dieser zueinander wird der
zu Fig. 5 beschriebene Spalt zwischen den Umlenkrollen 27 vermieden.
Die z.B. ebenfalls als Saugerbalken ausgebildeten Haltemittel 57,58
sind dementsprechend unterschiedlich lang. Mit 59,60 sind zweite
Verstellmittel für die Umsetzbewegung 44,45 der Blechteile 3
angedeutet. Mit 61 sind Zwischenablagen positioniert für eine zwischenzeitliche
Ablage auf halbem Transportweg, auf etwa halben Abstand,
