Bei einer ähnlichen Presse nach dem DE-GM 17 44 184 besteht das Druckübertragungsorgan aus einer Schiene, die kolbenartig in einer Preßbrücke parallel zu sich selbst verstellbar ist und sich daher mit ihrer Preßfläche ebenfalls nicht Unregelmäßigkeiten in der Oberfläche eines Werkstücks anpassen kann.In a similar press according to DE-GM 17 44 184, the pressure transmission element consists of a Rail, which is adjustable like a piston in a press bridge parallel to itself and therefore with its Pressing surface can also not adapt to irregularities in the surface of a workpiece.

Aufgabe der Erfindung ist es, eine Presse nach dem Oberbegriff des Patentanspruchs 1 anzugeben, bei der sich die Preßfläche des Druckübertragungsorgans Unregelmäßigkeiten eines Werkstücks anpassen kann, insbesondere eines mit Hilfe der Presse zu vulkanisierenden Werkstücks.The object of the invention is to provide a press according to the preamble of claim 1 in which the pressing surface of the pressure transmission member can adapt to irregularities of a workpiece, in particular a workpiece to be vulcanized with the aid of the press.

Die Lösung dieser Aufgabe ist im Kennzeichen des Anspruchs 1 angegeben.The solution to this problem is given in the characterizing part of claim 1.

Maßgeblich ist, daß nach der Erfindung das Druckübertragungsorgan flexibel und frei beweglich gehalten ist, was zur Folge hat, daß sich seine Preßfläche Unregelmäß'gkeiten in der Oberfläche des Werkstücks anpassen kann.It is essential that, according to the invention, the pressure transmission member is kept flexible and freely movable is what has the consequence that its pressing surface Irregular'gkeiten can adjust in the surface of the workpiece.

Vorteilhafte Ausgestaltungen sind in den Unteransprüchen angegeben.Advantageous refinements are given in the subclaims.

Anspruch 3 hat zur Folge, daß unterschiedlich breite Werkstücke gepreßt werden können. Die Breite isi allein durch die Länge der vorgesehenen Profilteile begrenzt. Claim 3 has the consequence that workpieces of different widths can be pressed. The breadth is alone limited by the length of the intended profile parts.

Die Lehre des Anspruchs 4 führt dazu, daß sich das Druckübertragungsorgan nicht übermäßig verschieben kann. Den gleichen Zweck erfüllt die Lehre des Anspruchs 5.The teaching of claim 4 means that the pressure transmission member does not move excessively can. The teaching of claim 5 fulfills the same purpose.

Die Lehre des Anspruchs 6 sorgt in einfacher Weise dafür, daß das Druckübertragungsorgan nicht aus dem ihm zugeordneten Druckteil herausfallen kann.
Die Lehre des Anspruchs 7 hat zur Folge, daß unabhängig von einem Andruck des einen Druckteils an das andere Druckteil der auf das Werkstück ausgeübte Druck einstellbar ist.The teaching of claim 6 ensures in a simple manner that the pressure transmission element cannot fall out of the pressure part assigned to it.
The teaching of claim 7 has the consequence that the pressure exerted on the workpiece can be adjusted regardless of whether the one pressure part is pressed against the other pressure part.

Die Lehre des Anspruchs 8 hat zur Folge, daß bei einem relativen Verkippen der Druckteile gegeneinander eine noch weitergehende Möglichkeit der Anpassung der Preßflächen an die Oberflächen des Werkstücks möglich ist.The teaching of claim 8 has the consequence that with a relative tilting of the pressure parts against each other an even more extensive possibility of adapting the pressing surfaces to the surfaces of the workpiece is possible.

Die Lehre des Anspruchs 9 hat zur Folge, daß die beiden Druckteile sicher gegeneinander geführt werden können.The teaching of claim 9 has the consequence that the two pressure parts are safely guided against each other can.

Die Lehre des Anspruchs 10 hat zur Folge, daß, insbesondere beim Vulkanisieren, das Pressen unter einer vorgegebenen Temperatur erfolgen kann.
Die Erfindung wird im Folgenden an einem Ausführungsbeispiel unter Hinweis auf die beigefügten Zeichnungen erläutert.The teaching of claim 10 has the consequence that, especially during vulcanization, the pressing can take place below a predetermined temperature.

In the bottom of the housing 4, a recess 6 is formed which extends over the entire length of the housing 4 Housing 4 is formed in one piece by two elongated legs 10 on its upper side in an elongated, movable ram 8 attached The two legs 10 run essentially parallel to each other and delimit a receiving space 12 for the ram 8.

In der Vertiefung 6 befindet sich ein aus flexiblem Material, beispielsweise aus Gummi, bestehendes, ausdehnbares, röhrenförmiges Oigan 14, das aufgeblasen werden kann, um, wie in F i g. 1 gezeigt, die Vertiefung 6 im wesentlichen auszufüllen.In the recess 6 there is an expandable material made of flexible material, for example rubber, tubular oigan 14 that can be inflated to form, as shown in FIG. 1, the recess 6 essentially to be filled out.

Ein langgestrecktes, streifenförmiges Druckübertragungsorgan 16 aus flexiblem Material, beispielsweise aus synthetischem Gummi, ist in der Vertiefung 6 angeordnet und erstreckt sich über die ganze Länge der Verliefung 6. Die Breite des Druckübertragungsorgans 16 ist gleich der Breite oder geringfügig kleiner als die Breite der Vertiefung 6. Die Unterseite des Druckübertragungsorgans 16 bildet eine ebene Preßfläche 17 des Druckteils 2. Das Druckübertragungsorgan 16 und das ausdehnbare Organ 14 sind in der Vertiefung 6 durch ein Abschlußteil 18, das sich über die ganze Länge der Vertiefung 6 erstreckt, in Position gehalten. Längsränder 20 des Abschlußteils 18 sind an Seiten 22 und 24 des Gehäuses 4 befestigt.An elongated, strip-shaped pressure transmission element 16 made of flexible material, for example made of synthetic rubber, is arranged in the recess 6 and extends over the entire length of the course 6. The width of the pressure transmission element 16 is equal to or slightly smaller than the width of the recess 6. The underside of the pressure transmission member 16 forms a flat pressing surface 17 of the pressure part 2. The pressure transmission element 16 and the Expandable organs 14 are in the recess 6 by a closure part 18, which extends over the entire length of the recess 6 extends, held in position. Longitudinal edges 20 of the end part 18 are on sides 22 and 24 of the housing 4 attached.

Ein fest gelagertes, unteres Druckteil 26 weist ein im wesentlichen starres, langgestrecktes Gehäuse 28 aus Metall mit einer Vertiefung 30 auf. Die Oberseite 32 des Gehäuses 28 ist als ebene Preßfläche 32 ausgebildet. Am Boden der Vertiefung 30 ist ein elektrisches Heizelement 34 zum Heizen des Gehäuses 28 angebracht. Das 1 lci/.element 34 ist mit einer isolierenden Schicht 36 aus faserigem Material, beispielsweise Steinwolle, bedeckt, um den Wärmefluß von der Preßfläche 32 nach unten zu mindern.A fixed, lower pressure part 26 has a substantially rigid, elongated housing 28 Metal with a recess 30. The top 32 of the housing 28 is designed as a flat pressing surface 32. At the An electrical heating element 34 for heating the housing 28 is attached to the bottom of the recess 30. That 1 lci / .element 34 is made with an insulating layer 36 fibrous material, for example rock wool, covered in order to reduce the flow of heat from the pressing surface 32 downwards reduce.

Das Gehäuse 28 ist über eine starre Schicht 40 aus wärmeisolierendem Material, beispielsweise harzgetränktem Gewebe, auf einem Rahmenteil 38 der Presse gelagert.The housing 28 is covered by a rigid layer 40 of heat-insulating material, for example resin-impregnated Tissue, mounted on a frame part 38 of the press.

Die Druckteile 2,26 nach F i g. 1 sind in einer schemalisch in Fig. 2 dargestellten Presse montiert, die einen C-förmigen, auf einem Tisch 44 befestigten Rahmen 42 aufweist. Das obere Druckteil 2 ist über die Ramme 8 an den Rahmen 42 relativ zu diesem bewegbar befestigt. Das untere Druckteil 26 ist über das Rahmenteil 38 und ein unteres, am Rahmen 42 angebrachtes, langgestrecktes Teil 46 am Rahmen 42 befestigt. Eine Preßluftquelle 48 ist durch eine Rohrleitung 50 mit einen Regulierventil 52 und dieses durch eine Rohrleitung 54 mit dem ausdehnbaren Organ 14 im oberen Druckteil 2 verbunden. Die Preßluftquelle 48 wird vorzugsweise von einer nicht dargestellten Pumpe versorgt.The pressure parts 2, 26 according to FIG. 1 are in a schematic 2, which has a C-shaped frame 42 fastened to a table 44 having. The upper pressure part 2 is fastened to the frame 42 via the ram 8 so as to be movable relative to the latter. The lower pressure part 26 is over the frame part 38 and a lower, attached to the frame 42, elongated Part 46 attached to frame 42. A source of compressed air 48 is through a conduit 50 with a regulating valve 52 and this is connected by a pipe 54 to the expandable member 14 in the upper pressure part 2. The compressed air source 48 is preferably supplied by a pump, not shown.

Die Arbeitsweise der Presse wird nun für einen Fall beschrieben, in dem sie in einem Vulkanisierverfahren /um Verbinden zweier Platten aus Gummi oder gummiähnlichem Material eingesetzt ist. Dieses Verfahren ist aber nur als Beispiel zu verstehen, denn die Presse kann auch anderweitig verwendet werden.The operation of the press will now be described for a case where it is in a vulcanizing process / to join two plates made of rubber or rubber-like material is used. This procedure is but only to be understood as an example, because the press can also be used for other purposes.

Der Arbeitsspalt zwischen den Preßflächen 17 und 32 des oberen und unteren Druckteils 2 und 26 der Presse wird zuerst durch Verstellen der Ramme 8 und damit des Druckteils 2 relativ zum Rahmen 42 entsprechend der Dicke des zu pressenden Werkstücks eingestellt. Das Heizelement 34 des unteren Druckteils 26 wird eingeschaltet und abgewartet, bis das untere Druckteil 26 auf eine vorgegebene Temperatur aufgeheizt ist. Das untere Druckteil 26 wird auf dieser vorgegebenen Temperatur durch einen nicht dargestellten, am Heizelement 34 angeschlossenen Thermostaten gehalten. Zwei zu verbindende Platten 56 und 58 aus Gummi oder gummiartigem Material werden dann so angeordnet, daß sich ihre Ränder auf der Preßfläche 32 überlappen, wobei eine dünne Schicht eines Streifens 60 aus unvulkanisiertem Material zwischen die sich überlappenden Ränder gelegt wird. Der Streifen 60 besteht aus einem Material, das mit dem Material der zu verbindenden Platten 56, 58 verträglich und von derselben Art ist. Dann wird das Regulierventil 52 geöffnet, so daß Preßluft aus der Preßluftquelle 48 dem ausdehnbaren Organ 14 im oberen Druckteil 2 zugeführt wird. Dadurch wird über die Preßfläche 17 des Druckübertragungsorgans 16 auf die sich überlappenden Ränder der Platten 56,58 ein Druck ausgeübt. Der Druck innerhalb des ausdehnbaren Organs 14 und folglich auch der Druck auf die sich überlappenden Ränder wird in Abhängigkeit von der Vulkanisierungseigenschaft des Streifens 60 für eine vorgegebene Zeit auf einer vorgegebenen Höhe gehalten. Am Ende der vorgegebenen Zeit wird das Regulierventil 52 geschlossen und dadurch der auf die sich überlappenden Ränder ausgeübte Druck gemindert. Nicht dargestellte Mittel, z. B. ein Überdruckventil, sind zum Entspannen des Drucks im ausdehnbaren Organ 14, soweit erforderlich, vorgesehen. Die Platten 56 und 58, die nun mitein ander verbunden sind, werden dann aus der Presse genommen. The working gap between the pressing surfaces 17 and 32 of the upper and lower pressure parts 2 and 26 of the press is first by adjusting the ram 8 and thus the pressure part 2 relative to the frame 42 accordingly the thickness of the workpiece to be pressed. The heating element 34 of the lower pressure part 26 is switched on and waited until the lower pressure part 26 is heated to a predetermined temperature. That lower pressure part 26 is at this predetermined temperature by a not shown, on the heating element 34 connected thermostats held. Two plates 56 and 58 made of rubber or rubber-like to be connected Materials are then arranged so that their edges overlap on the pressing surface 32, wherein a thin layer of strip 60 of unvulcanized material between the overlapping edges is placed. The strip 60 is made of a material that is compatible with the material of the panels to be joined 56, 58 is compatible and of the same kind. Then the regulating valve 52 is opened so that compressed air from the Compressed air source 48 is supplied to the expandable member 14 in the upper pressure part 2. This will use the Pressing surface 17 of the pressure transmission member 16 on the overlapping edges of the plates 56,58 a pressure exercised. The pressure within the expandable organ 14 and consequently also the pressure on the overlapping ones Edges is determined depending on the vulcanization property of the strip 60 for a given Time kept at a predetermined level. At the end of the predetermined time, the regulating valve 52 closed, thereby reducing the pressure exerted on the overlapping edges. Not shown Medium, e.g. B. a pressure relief valve, are to relieve the pressure in the expandable organ 14, if necessary, intended. The plates 56 and 58, which are now connected to each other, are then removed from the press.

Der durch das ausdehnbare Organ 14 auf das jeweilige Werkstück ausgeübte Druck ist eine direkte Funktion des Drucks der dem ausdehnbaren Organ 14 zugeführten Luft. Es ist kein dazwischenliegendes, mechanisches Koppelelement, das den Druck ändern könnte, vorhanden. Deshalb kann man den tatsächlich auf das Werkstück ausgeübten Druck genau steuern. Es ist auch möglich, das Werkstück einer oder mehrerer Druckstufen zu unterwerfen, indem der Druck im ausdehnbaren Organ 14 stufenweise erhöht oder erniedrigt wird. Wichtig ist, daß der durch das ausdehnbare Organ 14 ausgeübte Druck über die ganze Fläche des Werkstücks gleichmäßig ist.The pressure exerted on the workpiece by the expandable member 14 is a direct function the pressure of the air supplied to the expandable organ 14. It is not an intermediate, mechanical one Coupling element that could change the pressure is present. That's why you can actually refer to that Precisely control the pressure exerted on the workpiece. It is also possible to apply one or more pressure levels to the workpiece by gradually increasing or decreasing the pressure in the expandable member 14. It is important that the pressure exerted by the expandable member 14 be over the entire surface of the workpiece is even.

Zur Beschickung des ausdehnbaren Organs 14 kann statt Preßluft jedes pneumatische oder hydraulische Fluid verwendet werden. Die Preßflächen 17, 32 der Druckteile 2, 26 brauchen nicht eben zu sein, sondern können auch zueinander komplementär gekrümmt oder anders geformt sein.Instead of compressed air, any pneumatic or hydraulic system can be used to feed the expandable member 14 Fluid can be used. The pressing surfaces 17, 32 of the pressure parts 2, 26 do not need to be flat, but can also be curved in a complementary manner to one another or shaped differently.

Die Presse kann für viele Arten von Preßvorgängen benutzt werden, z. B. auch zum Formen von Blech.The press can be used for many types of pressing operations, e.g. B. also for forming sheet metal.
