Abstract

The invention relates to a compressed-air device which is arranged in the press table of a single-acting drawing press and comprises compressed-air cylinders on the piston rods of which a common pressure cheek is arranged. Compressed-air devices of this kind are used essentially as so-called drawing cushions. In the case of the known compressed-air devices, all the cylinders were supplied with regulable compressed air via a common compressed-air reservoir. Here, the force of the individual cylinders was in each case equal. During the drawing operation on asymmetric drawn parts, difficulties arose due to the differing drawing characteristics of some regions of the material of the drawn part. To remedy these circumstances, it is proposed according to the invention that, as can be seen from the drawing, each individual cylinder 1 to 4 of the compressed-air device be connected to its own compressed-air reservoir 5 to 8. It is thereby possible to supply the cylinders 1 to 4 with different pressures. <IMAGE>

Description

Drucklufteinrichtung im PressentischCompressed air device in the press table

Die Erfindung betrifft eine einer einfach wirkenden Ziehpresse angeordnete Drucklufteinrichtung im Pressentisch, welche aus Druckluftzylindern besteht, auf deren Kolbenstangen eine gemeinsame Druckwange angeordnet ist. Derartige Drucklufteinrichtungen werden im wesentlichen als sogenannte Ziehkissen eingesetzt. Bei den bekannten Drucklufteinrichtungen wurden alle Zy#linder über einen gemeinsamen Druckluftbehälter mit regulierbarer Druckluft versorgt. Hierbei war die Kraft der einzelnen Zylinder jeweils gleich gross.The invention relates to a single-acting drawing press Compressed air device in the press table, which consists of compressed air cylinders the piston rods of which a common pressure cheek is arranged. Such compressed air devices are mainly used as so-called drawing cushions. With the known compressed air devices all cylinders were connected to a common compressed air tank with adjustable Compressed air supplied. The force of the individual cylinders was the same in each case great.

Werden mit einer solchen Drucklufteinrichtung beispielsweise grosse asymmetrische Ziehteile hergestellt, ergaben sich Schwierigkeiten hinsichtlich der unterschiedlichen Haltekräfte in verschiedenen Teilbereichen der Ziehteile.With such a compressed air device, for example, large produced asymmetrical drawn parts, difficulties arose with regard to the different holding forces in different areas of the drawn parts.

Hier setzt nun die vorliegende Erfindung ein und hat sich zur Aufgabe gestellt, die vorerwähnte Schwierigkeit mit einfachen Mitteln zu vermeiden.This is where the present invention comes in and has as its object posed to avoid the aforementioned difficulty with simple means.

Erfindungsgemäss wird dieses bei einer Drucklufteinrichtung der eingangs beschriebenen Ausführung dadurch erreicht, dass jeder einzelne Zylinder der Drucklufteinrichtung an einen eigenen Druckluftbehälter angeschlossen ist. Dabei ist es von Vorteil, dass den Druckluftbehältern je eine Reguliervorrichtun vorgeschaltet ist.According to the invention, this is the above in a compressed air device described embodiment achieved in that each individual cylinder of the compressed air device is connected to its own compressed air tank. It is an advantage that a regulating device is connected upstream of each of the compressed air tanks.

Durch die erfindungsgemässe Ausgestaltung ist es nunmehr möglich, den unterschiedlich auftretenden Belastungen durch entsprechend unterschiedliche Beaufschlagung der einzelnen Zylinder zu entsprechen.Due to the design according to the invention, it is now possible the different loads occurring due to correspondingly different To correspond to the loading of the individual cylinders.

Die Erfindung wird anhand einer Zeichnung, die ein beliebiges Ausführungsbeispiel darstellt, näher erläutert. Sie zeigt eine Draufsicht auf die Drucklufteinrichtungen unter Weglassen der Druckwange im geschnittenen Zustand der Kolbenstangen la bis 4a der Zylinder 1 bis 4.The invention is based on a drawing showing any exemplary embodiment represents, explained in more detail. she shows a top view of the compressed air facilities omitting the pressure cheek in the cut state of the piston rods la bis 4a of cylinders 1 to 4.

Die einzelnen Zylinder 1 bis 4 sind über Druckluftleitungen 13 bis 16 mit eigenen Druckluftbehältern 5 bis 8 verbunden.The individual cylinders 1 to 4 are via compressed air lines 13 to 16 connected to their own compressed air tanks 5 to 8.

Zur Einstellung des jeweils in den Zylindern 1 bis 4 gewünschten Druckes sind den Zylindern 1 bis 4 Reguliervorrichtungen 9 bis 12 vorgeschaltet.To set the pressure required in cylinders 1 to 4 regulating devices 9 to 12 are connected upstream of cylinders 1 to 4.
