Abstract
Description
Die Erfindung betrifft eine Pressenanlage nach dem Oberbegriff des Anspruchs 1.The invention relates to a press system according to the preamble of
Die Bearbeitung von Blechteilen (Werkstücken) erfolgt in einer solchen Pressenanlage in mehreren Bearbeitungsschritten. Die Notwendigkeit der Verringerung von Investitions- und Betriebskosten führte zur Zusammenlegung der auf Einzelpressen in Pressenstraßen durchgeführten Bearbeitungsschritte in kompakte, mehrstufige Mehrständerpressen.Sheet metal parts (workpieces) are processed in such a press system in several processing steps. The need to reduce investment and operating costs led to the merging of the processing steps carried out on individual presses in press lines into compact, multi-stage multi-column presses.
Anhand der Figuren 1A bis 1F ist in der DE 39 05 069 die bisherige Entwicklungsrichtung von derartigen Pressenanlagen aufgezeigt.The previous development direction of such press systems is shown in FIGS. 1A to 1F in DE 39 05 069.
Ziel der Erfindung ist es, die Investitionskosten und Betriebskosten derartiger Pressenanlagen wesentlich zu senken. Nach der Aufgabe der Erfindung soll dieses Ziel erreichbar sein durch Verringerung der Bauteile-Anzahl und durch Übernahme - Integrieren - mehrerer Funktionen in verbleibende Bauteile.The aim of the invention is to significantly reduce the investment costs and operating costs of such press systems. According to the object of the invention, this goal should be achievable by reducing the number of components and by taking over - integrating - multiple functions into remaining components.
Die erfindungsgemäße Aufgabe ist gelöst bei einer Pressenanlage nach dem Oberbegriff des Anspruchs 1 durch die diesen kennzeichnenden Merkmale. Die gegenständlichen Merkmale des weiteren Anspruchs sind Ausgestaltung nach der Erfindung.The object of the invention is achieved in a press system according to the preamble of
Von Vorteil hierbei ist die kompakte, kurze Pressenanlage unter Fortfall von Zwischenablagen und die Verringerung der Pressenantriebselemente.The compact, short press system with the elimination of clipboards and the reduction of the press drive elements are advantageous here.
Anhand von in der Zeichnung dargestellten Ausführungsbeispielen soll die Erfindung im folgenden näher erläutert werden.The invention will be explained in more detail below on the basis of exemplary embodiments illustrated in the drawing.

Die gezeigte Pressenanlage weist ein Kopfstück 1 auf, das sich über die Arbeitsstufen 6 erstreckt. Das Kopfstück 1 ist auf Pressenständern 2 abgestützt, die über Ständerquertraversen 3 auf dem Fundament 12 aufgestellt sind. Diese Bauelemente der Pressenanlage sind vermittels Spannanker 4 verspannt. Auf den Ständerquertraversen 3 ist ein Pressentisch 5 aufgesetzt. Auf diesen ist ein Schiebetisch 11 mit einem Werkzeugunterteil 10 bzw. Satz an Werkzeugunterteilen geschoben. Im oberen Bereich der Pressenanlage ist zunächst ein Außenstößel 7 vermittels Führungen 23 in Führungen 22 (Fig. 4) an den Pressenständern 2 gelagert und über Pleuel 17 heb- und senkbar.The press system shown has a
Der Außenstößel 7 erstreckt sich über mehrere Arbeitsstufen 6. Der Antrieb des bzw. der Stößel erfolgt über motorbetriebene Getriebe 19, 20 in dem Kopfstück 1. Durch die Gesamt-Pressenanlage erstreckt sich eine Umsetzeinrichtung für die von Arbeitsstufe 13, 6 zu Arbeitsstufe 6 zu bewegenden Blechteile, die aus z.B. im Takt der Stößel / Pressenanlage angetriebenen Schwinghebeln 14 besteht, die an Schienen 15 angreifen, die Greifzeuge 16 tragen oder direkt an Greifzeuge tragende Mittel 16, die Saugerbalken sein können, angreifen.The
Mit 13 ist eine den Arbeitsstufen 6 vorgeschaltete Ziehstufe beziffert mit einem Ziehstößel 36, einem Werkzeugoberteil 37 und einem Werkzeugunterteil 38. Zwischen Ziehstufe 13 und erster Bearbeitungsstufe 6 ist eine Zwischenablage 42 angeordnet, die den Abstand zwischen diesen Bearbeitungsstufen halbiert.With 13 a drawing stage upstream of the
Die Pleuel 17 greifen in den Anlenkpunkten 18 bzw. 40, wie es in den Fign. 2 und 6 näher veranschaulicht ist, am Außenstößel 7 bzw. dem Stößel 39 an. Die Erfindung sieht hier zwei Möglichkeiten vor, wobei sich die erste Ausgestaltung auf den direkten Angriff der Pleuel 17 an dem Außenstößel 8 entsprechend Fig. 2 bezieht. Die zweite Ausgestaltung gemäß Fig. 6 sieht für jeden der z.B. vier Anlenkpunkte 40 der Pleuel 17 an dem Stößel, hier 39, eine Absicherung in Form einer Überlastsicherung 41 vor. Die Pleuel 17 sind in dem jeweiligen Anlenkpunkt 40 mit einem Druckkolben 44 verbunden. Der unterhalb des Druckkolbens 44 vorgesehene Druckraum 43 ist für den Pressenbetrieb über eine Druckleitung 33 auf eine definierte Druckhöhe eingestellt.The connecting
Aus den Fign. 1, 3 und 4 ist der Außenstößel 7 erkennbar, in den entsprechend der Anzahl an Arbeitsstufen 6, hier vier Innenstößel 8 eingesetzt sind. Die Innenstößel 8 sind vermittels Führungen 24 in dem Außenstößel 7 heb- und senkbar gelagert.From Figs. 1, 3 and 4, the
Fig. 4 läßt erkennen, daß die Mitten der Pleuel 17 und die Mitten der auf gegenüberliegenden Seiten der Pressenanlage befindlichen Spannanker 4 auf einer gemeinsamen Linie 21 angeordnet sind zur Erzielung günstiger Belastungs- und Kraftangriffspunkte. Die Linie 21 ist eine Horizontale und verläuft quer / senkrecht zur Pressendurchlaufrichtung. Die Pressendurchlaufrichtung - Transportrichtung der Werkstücke - ist mit 35 positioniert. Entsprechend der Fign. 4 und 5 weist jeder Innenstößel 8 Konsolbleche 34 auf, auf denen je eine Spindel 32 starr befestigt ist, die in Richtung nach oben weist. Die Spindel 32 wirkt mit einem von einer motorgetriebenen Schnecke 30 drehbewegbaren Schneckenrad 31 in Art einer Muttern-Spindel-Verbindung zur Höheneinstellung des aufgelegten Werkzeugs zusammen. Auf dem Schneckenrad 31 liegt der Kolben 29 eines Druckzylinders 27 auf. Oberhalb des Kolbens 29 ist ein Druckraum 28 vorgesehen, der im Betriebszustand der Pressenanlage mit Druck über die Druckleitung 33 beaufschlagt ist.Fig. 4 shows that the centers of the connecting
Die Schnecken-, Schneckenrad-, Spindellösung (30, 31, 32) ermöglicht die Einstellung der Innenstößel 8 in dem Außenstößel 7. Über diese Mittel ist somit die Höheneinstellung 26 der Werkzeuge durchführbar. Die Druckzylinder 27, Druckraum 28, Kolben 29 und Spindel 32 - Lösung ermöglicht die Absicherung der Arbeitsstufen bei Überlast als Überlastsicherung 25.The worm, worm wheel and spindle solution (30, 31, 32) enables the setting of the
