In den Figuren sind gleiche Teile gleich positioniert. Es versteht sich, daß von der Pressenanlage nur die pressenspezifischen Baugruppen und die erfindungswesentlichen Bauteile und diese dann in starker Verkleinerung dargestellt sind. Fig. 1 zeige den Aufstellungsort einer Pressenanlage mit einer Ziehstufe 1, die auch als Einzelpresse vorgesetzt werden kann. Mit der Ziffer 2 sind Folgestufen einer Drei-Ständerpresse gekennzeichnet, die hier zwei und drei, insgesamt fünf Arbeitsstufen aufweist. Mit 6 sind die Bereiche von Pressenständern angegeben. Es ist zu erkennen, daß ein Ständer mit einem Doppel-Zuganker 13 ausgeführt ist. Anstelle eines Zugankers größeren Durchmessers je Ständerbereich 6 sind hier z.B. für den mittleren von drei Ständerbereichen 6, über die sich ein Pressenstößel 7 (Fig. 2) erstreckt, jeweils zwei Zuganker 13 mit wesentlich verringertem Querschnitt angeordnet. Einander gegenüberstehende Ständer bzw. Ständerbereiche 6 bilden ein Ständerpaar 12. Mit 21 sind Abfallschächte beziffert, die sich über die Breite des Pressenraumes erstrecken und vor und nach jeder Folgestufe 2 angeordnet sein können. Die Größe der Abfallschächte, insbesondere deren Breite in Pressendurchlaufrichtung gemessen, ist abfallabhängig. Die Erfindung zielt hier auf den Wegfall der Zwischenablagen in den sogenannten Leerstufenbereichen und auf eine Verringerung der Breite der Ständerbereiche 6.Identical parts are positioned identically in the figures. It understands that only the press-specific assemblies of the press system and the components essential to the invention and these then in strong Reduction are shown. Fig. 1 show the location of a Press system with a drawing stage 1, which can also be used as a single press can be set. With the number 2, subsequent stages are one Three-column press featured, here two and three, in total has five working levels. With 6 are the areas of press stands specified. It can be seen that a stand with a Double tie rod 13 is executed. Instead of a tie rod larger Diameter per stand area 6 are e.g. for the middle of three stand areas 6, over which a press ram 7 (FIG. 2) extends, two tie rods 13 each with a substantially reduced cross section arranged. Opposing stands or areas of stands 6 form a pair of stands 12. With 21 waste chutes are numbered, which extend across the width of the press room and before and can be arranged after each subsequent stage 2. The size of the waste chutes, especially their width in the direction of the press run measured, is dependent on waste. The invention aims at the elimination the clipboards in the so-called empty space areas and on a reduction in the width of the stand areas 6.

In Fig. 2 ist eine Mehrständerpresse als Folgestufenpresse gezeigt, wobei die vorgeschaltete Ziehpresse mit der Ziehstufe 1 auch entfallen kann. Diese Mehrständerpresse mit z.B. drei Pressenständern - Ständerbereiche 6 - ist fundamentseitig über die Breite der Mehrständerpresse sich erstreckende Querträger 4 aufgestellt. Mit 3 sind Pressentische positioniert, die fest auf den Quertraversen 4 aufgesetzt sind, die einteilig ausgeführt sein können und die Schiebetische mit Werkzeugen 8 tragen. Die Werkzeugoberteile sind an dem im Betrieb einstückigen Pressenstößel 7 befestigt. 2 shows a multi-column press as a subsequent stage press, the upstream drawing press with drawing stage 1 also can be omitted. This multi-column press with e.g. three press stands - Stand areas 6 - is on the foundation side across the width of the multi-column press extending cross member 4 set up. With 3 are Press tables positioned, which are firmly placed on the crossbars 4 are that can be made in one piece and the sliding tables wear with tools 8. The upper parts of the tool are in operation one-piece press ram 7 attached.

Die Pressenständer 6 sind jeweils vor und hinter dem Pressenstößel 7 durch Längsträger 5 verbunden. Im Bereich oberhalb der Pressenständer 6 sind Getriebekästen 11 aufgesetzt. Die Getriebekästen 11 dienen der Aufnahme von Bewegungsumlenkmitteln, ggf. auch von z.B. hydraulischen Antriebsmitteln für die auf- und abgehende Bewegung des Pressenstößels 7. Der Antrieb der Mittel in den Antriebskästen 11 erfolgt über Motore 11, eine Schwungscheibe 19 und eine getriebene Welle 20 außerhalb der Getriebekösten 11, wie in Fig. 4 gezeigt. Der Pressenstößel 7 wird hier in drei Ebenen entsprechend der Anzahl Ständerbereiche 6 über aus den Antriebskästen 11 nach unten herausgeführte Pleuel 17 angetrieben. Durch die Pressenanlage ist eine Umsetzeinrichtung 9 für den Transport der Blechteile in den Stufen im Pressendurchlauf sich erstreckend hindurchgeführt.The press stands 6 are in front of and behind the press ram 7 connected by side members 5. In the area above the press stands 6 gearboxes 11 are placed. The gear boxes 11 serve to accommodate motion deflection devices, possibly also e.g. hydraulic Driving means for the up and down movement of the Press ram 7. The means are driven in the drive boxes 11 via motors 11, a flywheel 19 and a driven shaft 20 outside the gear box 11, as shown in Fig. 4. Of the Press ram 7 is here in three levels according to the number of stand areas 6 via led out downwards from the drive boxes 11 Conrod 17 driven. A transfer device is through the press system 9 for the transport of the sheet metal parts in the stages in the press pass extending through.

Aus den Fig. 3, 4, 5, 7 und 9 ist die Doppelanordnung von Zugankern 13 im mittleren Ständerbereich 6 zu erkennen. Die Zuganker 13 insgesamt sind von Zugankerhülsen 14 für die Abstützung, Maßhaltigkeit und Kraftaufnahme umgehen. Entsprechend Fig. 5 ist der Pressenstößel 7 in Längs- bzw. Linearlagern 23 heb- und senkbar gelagert. Die Krafteinleitung, Angriffspunkt der Pleuel 17 am Pressenstößel 7 ist durch Kreise 18 gekennzeichnet.3, 4, 5, 7 and 9 is the double arrangement of tie rods 13 in the central stand area 6. The tie rods 13 Overall, tie rod sleeves 14 for support, dimensional accuracy and bypass force. 5 is the press ram 7 in longitudinal or linear bearings 23 can be raised and lowered. The Force transmission, point of application of the connecting rod 17 on the press ram 7 indicated by circles 18.

Fig. 6 zeigt einen von mehreren Antriebskästen 11, hier den im mittleren Bereich des Pressenstößels 7 angeordneten Antriebskasten 11. Der Antriebskasten 11 ist oberhalb der Pressenständer 6 auf den sich vor und hinter dem Pressenstößel 7 erstreckenden Längsträgern 5 aufgesetzt und über vier Zuganker 22 mit Zugankerhülsen befestigt.Fig. 6 shows one of several drive boxes 11, here in the drive box 11 arranged in the middle region of the press ram 7. The drive box 11 is above the press stand 6 on the longitudinal beams 5 extending in front of and behind the press ram 7 attached and fastened via four tie rods 22 with tie rod sleeves.

Die Fign. 7 und 8 lassen von der Hauptwelle 20 (Fig. 4) bewegte Antriebsmittel, unter anderem ein Pleuel 17 mit der Krafteinleitung 18 in den Pressenstößel 7 erkennen. Die Mitten der Zuganker 13 eines Ständerpaares 12 und die Mitte der Krafteinleitung 18 - Pleuel 17 - in den Pressenstößel 7 liegen auf einer gemeinsamen Linie 16. Für die mittlere Krafteinleitung 18 liegen beide der hier erforderlichen Zuganker 13 auf dieser gemeinsamen Linie 16.The figures 7 and 8 move from the main shaft 20 (Fig. 4) Drive means, including a connecting rod 17 with the force transmission 18 recognize in the press ram 7. The centers of the tie rods 13 one Stand pair 12 and the center of the force transmission 18 - connecting rod 17 - in the press rams 7 lie on a common line 16. For the mean force 18 are both of the tie rods required here 13 on this common line 16.
