Abstract

The multi-stage press assembly, for working sheet metal, has a ram (7) extending over several working stages (6), directly coupled by connecting rods (17) free of pressure points at four points. The centres of each of two coupling points at a ram side and two clamping ties (4) facing each other in the press frame are on a common line (21) horizontal and at right angles to the line (35) through the press. The ram (7), as an outer ram, has inner rams (8) matching the number of working stages (6), moved vertically. At least one overload protection (25) is between each inner ram (8) and the outer ram (7), with a pressure zone in a pressure cylinder with a piston. The pressure zone is held under pressure through pressure channels for the press operation, the pistons and held under pressure through pressure channels for the press operation, the pistons and the inner rams (8) to give a vertical downwards movement to the pistons. Each overload protection unit (25), between the outer am (7) and each inner ram (8), works with a tool height adjustment. In the pressure cylinder of each overload protection unit (25), the piston acts on a worm wheel which meshes with a spindle rigidly fixed to the outer ram (7). A threaded nut coupling is between the spindle and the worm wheel. The worm wheel has a rotary adjustment through a powered screw.

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 head piece 1 which extends over the working stages 6. The head piece 1 is supported on press stands 2 which are set up on the foundation 12 by means of crossbeams 3. These components of the press system are clamped by means of tension anchors 4. A press table 5 is placed on the crossbeams 3. A sliding table 11 with a lower tool part 10 or a set of lower tool parts is pushed onto this. In the upper area of the press system, an outer tappet 7 is initially mounted on the press stands 2 by means of guides 23 in guides 22 (FIG. 4) and can be raised and lowered via connecting rods 17.

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 outer tappet 7 extends over several work stages 6. The drive or the tappet is carried out via motor-driven gears 19, 20 in the head piece 1. Through the entire press system, a conversion device extends for those to be moved from work stage 13, 6 to work stage 6 Sheet metal parts made from e.g. in the cycle of the tappet / press system, there are rocking levers 14 which engage rails 15, which carry gripping tools 16 or which directly engage gripping tools 16, which can be suction bars.

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 working stages 6 is numbered with a ram 36, an upper tool part 37 and a lower tool part 38. Between the drawing stage 13 and the first processing stage 6 an intermediate storage 42 is arranged, which halves the distance between these processing stages.

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 rods 17 engage in the articulation points 18 and 40, as shown in FIGS. 2 and 6 is illustrated in more detail on the outer plunger 7 and the plunger 39 respectively. The invention provides two possibilities here, the first embodiment relating to the direct engagement of the connecting rods 17 on the outer tappet 8 according to FIG. 2. The second embodiment according to FIG. 6 provides for each of the e.g. Four articulation points 40 of the connecting rods 17 on the tappet, here 39, provide protection in the form of an overload protection 41. The connecting rods 17 are connected to a pressure piston 44 in the respective articulation point 40. The pressure chamber 43 provided below the pressure piston 44 is set to a defined pressure level for the press operation via a pressure line 33.

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 outer plunger 7 can be seen, in which four inner plungers 8 are used, corresponding to the number of working stages 6. The inner plungers 8 are supported by guides 24 in the outer plunger 7 so that they can be raised and lowered.

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 rods 17 and the centers of the tension anchors 4 located on opposite sides of the press system are arranged on a common line 21 in order to achieve favorable loading and force application points. Line 21 is a horizontal line and runs transversely / perpendicular to the direction of the press run. The direction of press travel - the direction of transport of the workpieces - is positioned at 35. According to FIGS. 4 and 5, each inner tappet has 8 bracket plates 34, on each of which a spindle 32 is rigidly fastened, which points in the upward direction. The spindle 32 interacts with a worm wheel 31 which can be rotated by a motor-driven worm 30 in the manner of a nut-spindle connection for adjusting the height of the tool placed on it. The piston 29 of a pressure cylinder 27 rests on the worm wheel 31. A pressure chamber 28 is provided above the piston 29 and is pressurized via the pressure line 33 in the operating state of the press system.

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 inner plunger 8 in the outer plunger 7. The height adjustment 26 of the tools can thus be carried out via these means. The pressure cylinder 27, pressure chamber 28, piston 29 and spindle 32 solution enable the working stages to be protected in the event of an overload as an overload protection 25.
