Description

TECHNISCHES GEBIETTECHNICAL AREA

Die vorliegende Erfindung betrifft eine Pressvorrichtung nach dem Gegenstand von Anspruch 1.The present invention relates to a pressing device according to the subject matter of claim 1.

STAND DER TECHNIKSTATE OF THE ART

Pressvorrichtungen sind aus dem Stand der Technik bekannt. Beispielsweise offenbart die EP 2 340 899 eine derartige Pressvorrichtung.Pressing devices are known from the prior art. For example, the EP 2 340 899 such a pressing device.

Bei der Pressvorrichtung nach der EP 2 340 899 wirken zwei Hebel auf Pressbacken. Die Hebel sind an einem Pressbackenträger angelenkt und stehen mit diesem über jeweils einen Bolzen in Verbindung. Die Pressbacke ist dabei um den Bolzen relativ zum Pressbackenträger verschwenkbar ausgebildet. Der Bolzen nach der EP 2 340 899 wird über eine Schraube und zwei Deckel im Pressbackenträger gehalten.In the pressing device after EP 2 340 899 two levers act on pressing jaws. The levers are articulated on a pressing jaw carrier and are connected to it via a bolt in each case. The press jaw is designed to be pivotable about the bolt relative to the press jaw carrier. The bolt after the EP 2 340 899 is held in the press jaw carrier by a screw and two covers.

Auch sind Pressvorrichtungen bekannt geworden, bei welchen der Bolzen über lösbare Sicherungsringe im Pressbackenträger gehalten wird.Pressing devices have also become known in which the bolt is held in the press jaw carrier by means of detachable retaining rings.

Aus der EP1 786 598 ist eine Pressvorrichtung bekannt geworden, wobei eine Sollbruchstelle vorhanden ist, welche bei Auftreten einer zu grossen Kraft an einem definierten Ort bricht. Pro Bolzenöffnung ist dabei eine Sollbruchstelle angeordnet, was zum Problem führt, dass im Versagensfall eine oder beide der Sollbruchstellen aufreissen, wobei der Presshebel mitsamt des Lagerbolzens von der Pressvorrichtung sich mit grosser Energie von der Pressvorrichtung lösenFrom the EP1 786 598 a pressing device has become known, with a predetermined breaking point being present, which breaks at a defined location when too great a force occurs. A predetermined breaking point is arranged for each bolt opening, which leads to the problem that in the event of failure one or both of the predetermined breaking points tear open, with the pressing lever together with the bearing bolt detaching from the pressing device with great energy

Die DE 10 2004 016110 zeigt eine Pressvorrichtung nach dem Oberbegriff von Anspruch 1.the DE 10 2004 016110 shows a pressing device according to the preamble of claim 1.

DARSTELLUNG DER ERFINDUNGPRESENTATION OF THE INVENTION

Ausgehend von diesem Stand der Technik liegt der Erfindung eine Aufgabe zugrunde, eine Pressvorrichtung anzugeben, welche die Nachteile des Standes der Technik überwindet. Insbesondere soll die Pressvorrichtung sicherer zu bedienen sein.Proceeding from this prior art, the invention is based on the object of specifying a pressing device which overcomes the disadvantages of the prior art. In particular, the pressing device should be safer to use.

Diese Aufgabe löst der Gegenstand von Anspruch 1. Demgemäss umfasst eine Pressvorrichtung mindestens ein Trägerelement mit mindestens zwei Trägerlaschen, in welchen jeweils mindestens eine Trägeröffnung angeordnet ist, und mindestens ein Presselement mit mindestens einer Lageröffnung zum Aufbringen einer Presskraft auf einen Pressling, wobei das mindestens eine Presselement um mindestens eine Schwenkachse schwenkbar am Trägerelement gelagert ist. Jeweils ein die Lagerung sowie die Schwenkachse bereitstellender Bolzen erstreckt sich durch die mindestens eine Trägeröffnung und die Lageröffnung hindurch. Mindestens eine der Trägerlaschen ist mit einem grösseren Materialanteil ausgebildet, als die andere der Trägerlaschen.This object is achieved by the subject matter of claim 1. Accordingly, a pressing device comprises at least one carrier element with at least two carrier straps, in each of which at least one carrier opening is arranged, and at least one pressing element with at least one bearing opening for applying a pressing force to a compact, the at least one Pressing element is mounted pivotably about at least one pivot axis on the carrier element. One bolt each providing the bearing and the pivot axis extends through the at least one carrier opening and the bearing opening. At least one of the support tabs is formed with a larger proportion of material than the other of the support tabs.

Mit anderen Worten gesagt ist der Materialanteil des Trägerelements im Bereich der einen Trägerlasche grösser zum Materialanteil des Trägerelements Bereich der anderen Trägerlasche ausgebildet. Die Materialanteile zwischen den Trägerlaschen sind also unterschiedlich.In other words, the proportion of material in the carrier element in the area of one carrier tab is greater than the proportion of material in the carrier element in the area of the other carrier tab. The proportions of material between the carrier straps are therefore different.

Die Trägerlaschen sind bezüglich also des Materialanteils asymmetrisch ausgebildet.The carrier straps are therefore designed asymmetrically with regard to the proportion of material.

Durch die unterschiedliche Anordnung der einzelnen Materialanteile ergeht der Vorteil, dass im Versagensfall immer nur eine Trägerlasche versagen, also reissen oder brechen, kann. Ein gleichzeitiges Versagen von beiden Trägerlaschen kann ausgeschlossen werden. Folglich kann das Presswerkzeug sicherer bedient werden.The different arrangement of the individual material parts has the advantage that in the event of a failure, only one carrier flap can fail, i.e. tear or break. Simultaneous failure of both support straps can be ruled out. Consequently, the pressing tool can be operated more safely.

Unter der Ausdrucksweise "Materialanteil" wird ein bezüglich des Gewichts und Volumen grösser Ausbildung verstanden.The expression “material content” means a design that is larger in terms of weight and volume.

Der grössere Materialanteil bildet einen integralen Teil der Trägerlasche. Das heisst die Trägerlasche mit dem grösseren Materialanteil ist bezüglich ihrer Aussenform anders ausgebildet als die Trägerlasche ohne den grösseren Materialanteil.The major portion of material forms an integral part of the carrier flap. This means that the carrier tab with the greater proportion of material is designed differently in terms of its outer shape than the carrier tab without the greater proportion of material.

Der grössere Materialanteil weist vorzugsweise gleiche Materialeigenschaften wie der Rest der Trägerlasche auf.The larger proportion of material preferably has the same material properties as the rest of the carrier strap.

Zudem umfasst die Pressvorrichtung zwei beabstandet zueinander liegende Trägerelemente mit den besagten grösseren Materialanteilen Die beiden Trägerelemente sind derart zueinander angeordnet, dass die Trägerlasche mit dem grösseren Materialanteil des ersten Trägerelementes über der Trägerlasche ohne den grösseren Materialanteil des zweiten Trägerelementes liegt, und dass die Trägerlasche ohne den grösseren Materialanteil des ersten Trägerelementes über der Trägerlasche mit dem grösseren Materialanteil des zweiten Trägerelementes liegt.In addition, the pressing device comprises two spaced-apart carrier elements with said larger material portions. The two carrier elements are arranged relative to one another in such a way that the carrier tab with the larger material portion of the first carrier element lies above the carrier tab without the larger material portion of the second carrier element, and that the carrier tab without the larger proportion of material of the first carrier element lies above the carrier flap with the larger proportion of material of the second carrier element.

Mit anderen Worten gesagt sind die beiden Trägerelement nicht deckungsgleich, sondern gegengleich, zueinander angeordnet. Die beiden Trägerelemente sind bezüglich einer zwischen den beiden Trägerelementen verlaufenden Symmetrieebene asymmetrisch angeordnet.In other words, the two carrier elements are not arranged congruently, but oppositely arranged to one another. The two support elements are arranged asymmetrically with respect to a plane of symmetry running between the two support elements.

Diese bevorzugte Ausführungsform hat den Vorteil, dass im Falle eines Versagens einer der Trägerlaschen, der Bolzen an der anderen Trägerlasche weiterhin hält. Bricht also das erste Trägerelement im Bereich der Trägerlasche ohne den grösseren Materialanteil, so hält das Presselement nach wie vor im zweiten Trägerelement und zwar in der Trägerlasche mit dem grösseren Materialanteil. Somit wird ein Wegfliegen des Presselementes weitgehend verhindert.This preferred embodiment has the advantage that in the event of a failure of one of the carrier straps, the bolt on the other strap is still holding. Thus, if the first support element breaks in the area of the support strap without the larger material portion, the pressing element continues to hold in the second support element, specifically in the support strap with the larger material portion. This largely prevents the pressing element from flying off.

In dieser Ausführungsform erstreckt sich jeder Bolzen durch eine Trägerlasche, welche mit dem grösseren Materialanteil versehen ist und durch eine andere Trägerlasche, welche ohne den grösseren Materialanteil ausgebildet ist.In this embodiment, each stud extends through a carrier tab which is provided with the larger portion of material and through another carrier tab which is formed without the larger portion of material.

In einer Variante ist der besagte grössere Materialanteil des Trägerelements im Bereich der einen Trägerlasche bezüglich einer Symmetrieachse asymmetrisch zum Materialanteil des Trägerelements Bereich der anderen Trägerlasche ausgebildet.In one variant, said larger proportion of material of the carrier element in the region of one carrier strap is asymmetrical with respect to an axis of symmetry with respect to the material proportion of the carrier element region of the other carrier strap.

Die beiden Trägerlaschen sind also bezüglich der Symmetrieachse asymmetrisch ausgebildet.The two carrier straps are therefore designed asymmetrically with respect to the axis of symmetry.

Vorzugsweise verläuft die Symmetrieachse in einer Variante rechtwinklig zu einer die beiden Schwenkachsen verbindende Gerade, wobei die Symmetrieachse vorzugsweise mittig zwischen den beiden Schwenkachsen liegt. Die Gerade verläuft dabei rechtwinklig zu den Schwenkachsen. Die Symmetrieachse kann in einer weiteren Variante auch winklig geneigt zu der besagten Geraden verlaufen.In one variant, the axis of symmetry preferably runs at right angles to a straight line connecting the two pivot axes, with the axis of symmetry preferably lying centrally between the two pivot axes. The straight line runs at right angles to the pivot axes. In a further variant, the axis of symmetry can also run at an angle to said straight line.

In einer anderen Variante verläuft die Symmetrieachse durch die beiden Schwenkachsen und zwar rechtwinklig dazu.In another variant, the axis of symmetry runs through the two pivot axes, specifically at right angles to them.

Alternativ ist der besagte grössere Materialanteil der einen Trägerlasche bezüglich einer Symmetrieebene asymmetrisch zum Materialanteil der anderen Trägerlasche ausgebildet.Alternatively, said larger portion of material of one support tab is asymmetrical with respect to a plane of symmetry to the portion of material of the other support tab.

BESCHREIBUNG BEVORZUGTER AUSFÜHRUNGSFORMENDESCRIPTION OF PREFERRED EMBODIMENTS

In der Figur 1 und der Figur 4 wird eine Pressvorrichtung 1 gezeigt. Die hier gezeigte Pressvorrichtung ist eine sogenannte Pressbacke. In den Figuren 7 und 8 werden weitere Pressvorrichtungen gezeigt, welche die Gestalt von einer Pressschlinge (Figur 7) und die Gestalt von einer Zwischenbacke (Figur 8) aufweisen. In allen Figuren tragen gleiche Teile gleiche Bezugszeichen.In the figure 1 and the figure 4 a pressing device 1 is shown. The pressing device shown here is a so-called pressing jaw. In the Figures 7 and 8 further pressing devices are shown which have the shape of a press sling ( figure 7 ) and the shape of an intermediate jaw ( figure 8 ) exhibit. In all figures, the same parts bear the same reference numbers.

Die Pressvorrichtung 1 umfasst mindestens ein Trägerelement 2 und mindestens ein Presselement 7, 8. Das Trägerelement 2 weist mindestens zwei Trägerlaschen 3, 4 auf, in welchen jeweils mindestens eine Trägeröffnung 5, 6 angeordnet ist. Das heisst in jeder der Trägerlaschen 3, 4 ist je eine Trägeröffnung 5, 6 angeordnet. Das Presselement 7, 8 umfasst hier jeweils eine Lageröffnung 14, 15, mit welcher das Presselement 7, 8 zu den Trägerelementen 2 gelagert werden kann. Das Presselement 7, 8 dient zum Aufbringen einer Presskraft auf einen Pressling. Dabei ist das Presselement 7, 8 um eine Schwenkachse A1 bzw. A2 schwenkbar am Trägerelement 2 gelagert. Für die Lagerung ist pro Presselement 7, 8 je ein Bolzen 9, 10 vorhanden. Der Bolzen 9, 10 erstreckt sich dabei durch die Trägeröffnung 5, 6 der Trägerelemente 2 und durch die Lageröffnung 14, 15 am Presselement 7, 8 hindurch. Endseitig ist der Bolzen 9, 10 jeweils mit einem Sicherungselement 17, mit welchem der Bolzen in Verbindung steht gesichert.The pressing device 1 comprises at least one carrier element 2 and at least one pressing element 7, 8. The carrier element 2 has at least two carrier straps 3, 4, in each of which at least one carrier opening 5, 6 is arranged. This means that a carrier opening 5 , 6 is arranged in each of the carrier straps 3 , 4 . The pressing element 7 , 8 here includes a bearing opening 14 , 15 in each case, with which the pressing element 7 , 8 can be mounted relative to the carrier elements 2 . The pressing element 7, 8 is used to apply a pressing force to a compact. The pressing element 7, 8 is mounted on the carrier element 2 such that it can pivot about a pivot axis A1 or A2. A bolt 9 , 10 is provided for each pressing element 7 , 8 for storage. The bolt 9 , 10 extends through the support opening 5 , 6 of the support elements 2 and through the bearing opening 14 , 15 on the pressing element 7 , 8 . The end of the bolt 9, 10 is secured with a securing element 17, with which the bolt is connected.

Mindestens eine der Trägerlaschen 3, 4 ist mit einem grösseren Materialanteil ausgebildet, als die andere der Trägerlaschen 4, 3. In den gezeigten Ausführungsformen ist jeweils die Trägerlasche 3 mit einem grösseren Materialanteil 11 versehen. Die andere Trägerlasche, nämlich die Trägerlasche 4, weist keinen grösseren Materialanteil 11 auf. Das heisst, die Trägerlasche 3 ist asymmetrisch zur Trägerlasche 4 ausgebildet.At least one of the carrier tabs 3, 4 is formed with a larger proportion of material than the other of the carrier tabs 4, 3. In the embodiments shown, the carrier tab 3 is provided with a larger proportion of material 11 in each case. The other carrier strap, namely the carrier strap 4, does not have a larger proportion of material 11. This means that the carrier strap 3 is designed asymmetrically to the carrier strap 4 .

Die Anordnung des grösseren Materialanteils 11 ist in der Ausführungsform gemäss den Figuren 1 bis 3 unterschiedlich von denjenigen gemäss den Figuren 4 bis 6. Dies wird untenstehend noch detaillierter erläutert.The arrangement of the larger portion of material 11 is in the embodiment according to FIG Figures 1 to 3 different from those according to the Figures 4 to 6 . This is explained in more detail below.

Das Presselement 7, 8 ist in den Figuren 1 und 4 als Presshebel ausgebildet. Es sind dabei zwei Presshebel angeordnet, welche mit zwei Trägerelementen 2 miteinander verbunden sind. In der gezeigten Ausführungsform der Figuren 1 und 4 liegen zwei beabstandet zueinander angeordnete Trägerelemente 2 vor. Jedes der Trägerelemente 2 weist dabei eine Trägerlasche 3 mit dem besagten grösseren Materialanteil 11 auf.The pressing element 7, 8 is in the figures 1 and 4 designed as a press lever. Two pressing levers are arranged, which are connected to one another with two carrier elements 2 . In the embodiment shown figures 1 and 4 there are two carrier elements 2 spaced apart from one another. Each of the carrier elements 2 has a carrier strap 3 with said larger proportion of material 11 .

Die beiden Presshebel 7, 8 weisen mindestens zwei Pressbacken 20, 21 zum Aufbringen der Presskraft auf den Pressling auf. Die Schwenkachsen A1, A2 liegen parallel zueinander, wobei der eine Presshebel 7 um die eine Schwenkachse A1 und der andere Presshebel 8 um die andere Schwenkachse A2 derart von einer Ausgangslage in eine Presslage verschwenkbar sind, dass am Ende des Pressvorgangs die Pressbacken 7, 8 entlang der Schwenkachsen A1, A2 gesehen gemeinsam einen im wesentlichen geschlossenen Kreis bilden.The two pressing levers 7, 8 have at least two pressing jaws 20, 21 for applying the pressing force to the compact. The pivot axes A1, A2 lie parallel to one another, with one press lever 7 being pivotable about one pivot axis A1 and the other press lever 8 being pivotable about the other pivot axis A2 from an initial position into a pressing position such that at the end of the pressing process the pressing jaws 7, 8 can be moved along of the pivot axes A1, A2 together form a substantially closed circle.

Die beiden Trägerelemente 2 sind derart zueinander angeordnet, dass die Trägerlasche 3 mit dem grösseren Materialanteil 11 des ersten Trägerelementes über der Trägerlasche 4 ohne den grösseren Materialanteil des zweiten Trägerelementes 2 liegt. Die Trägerlasche 3 ohne den grösseren Materialanteil des ersten Trägerelementes liegt über der Trägerlasche 3 mit dem grösseren Materialanteil 11 des zweiten Trägerelementes 2. Das heisst, die Trägerlaschen sind bezüglich des grösseren Materialanteils 11 derart angeordnet, dass die grösseren Materialanteile 11 jeweils nicht gegenüberliegend voneinander sind. Mit anderen Worten liegen die Trägerelemente 2 derart, dass jeder Trägerlasche 3 mit dem grösseren Materialanteil 11 eine Trägerlasche 4 ohne dem grösseren Materialanteil zugeordnet ist. Jede der Achsen A1, A2 erstreckt sich also durch eine Trägerlasche 3 mit dem grösseren Materialanteil 11 und durch eine Trägerlasche 4 ohne den grösseren Materialanteil.The two carrier elements 2 are arranged relative to one another in such a way that the carrier tab 3 with the larger proportion of material 11 of the first carrier element lies above the carrier tab 4 without the larger proportion of material of the second carrier element 2 . The carrier tab 3 without the larger material portion of the first carrier element lies above the carrier tab 3 with the larger material portion 11 of the second carrier element 2. This means that the carrier tabs are arranged with respect to the larger material portion 11 in such a way that the larger material portions 11 are not are opposite each other. In other words, the carrier elements 2 are positioned in such a way that each carrier tab 3 with the larger proportion of material 11 is assigned a carrier tab 4 without the larger proportion of material. Each of the axes A1, A2 thus extends through a support bracket 3 with the larger proportion of material 11 and through a support bracket 4 without the larger proportion of material.

In der gezeigten Ausführungsform umfasst jedes der Trägerelemente zwischen den beiden Trägerlaschen 3, 4 zusätzlich noch eine Verbindungslasche 18 mit einer Öffnung 19. Die Verbindungslasche 18 kann die Pressvorrichtung 1 zu einer Maschine zur Aufbringung einer Presskraft auf die Presselemente 7, 8 verbunden werden.In the embodiment shown, each of the carrier elements between the two carrier straps 3, 4 also includes a connecting strap 18 with an opening 19. The connecting strap 18 can be connected to the pressing device 1 to form a machine for applying a pressing force to the pressing elements 7, 8.

Anhand der Figuren 2 und 3 wird nun eine erste mögliche Ausbildung der Trägerelemente 2 genauer erläutert. In dieser gezeigten Ausführungsform wird ein grösserer Materialanteil 11 auf der Frontfläche 13 der Trägerlasche 3 angeordnet. Dies kann von der Figur 3, welche die Seitenansicht zeigt, besonders gut erkannt werden. Der grössere Materialanteil 11 erstreckt sich also von der Frontfläche 13 zwischen den beiden Trägeröffnungen 5, 6 weg. Der grössere Materialanteil 11 erstreckt sich dabei vorzugsweise im Wesentlichen vollständig um die Trägeröffnung 5 herum. Die Ausdehnung ist hier um die gesamte Trägeröffnung vorzugsweise im Wesentlichen konstant. Der grössere Materialanteil 11 hat also die Form eines Rings, welcher sich um die Trägeröffnung 5 herum erstreckt. Alternativ kann der grössere Materialanteil 11 auch derart ausgebildet sein, dass dieser die Trägeröffnung 5 nur teilweise umgibt.Based on Figures 2 and 3 a first possible embodiment of the support elements 2 will now be explained in more detail. In this embodiment shown, a larger proportion of material 11 is arranged on the front surface 13 of the carrier flap 3 . This can from the figure 3 , which shows the side view, can be recognized particularly well. The larger portion of material 11 thus extends away from the front face 13 between the two carrier openings 5, 6. The larger portion of material 11 preferably extends essentially completely around the carrier opening 5 . The extent here is preferably essentially constant around the entire carrier opening. The larger portion of material 11 therefore has the shape of a ring which extends around the support opening 5 . Alternatively, the larger portion of material 11 can also be designed in such a way that it only partially surrounds the carrier opening 5 .

Die Frontfläche 13 ist die Fläche, welche den Presselementen 7, 8 abgewandt ist.The front surface 13 is the surface which faces away from the pressing elements 7,8.

Um den Effekt der Asymmetrie noch zu verstärken, wurde hier um die Trägeröffnung 6 herum im Bereich der Trägerlasche 4, das ist die Trägerlasche, welche ohne den grösseren Materialanteil ausgebildet ist, zusätzlich noch Material entfernt, sodass der Bereich um die Trägeröffnung 6 etwas dünner ausgebildet ist. Diese Materialentfernung ist aber optional.In order to further enhance the effect of asymmetry, additional material was removed around the strap opening 6 in the area of the strap strap 4, i.e. the strap strap that is designed without the larger proportion of material, so that the area around the strap opening 6 is made somewhat thinner is. However, this material removal is optional.

Bezüglich der Asymmetrie der beiden Trägerlaschen 3, 4 kann folgendes gesagt werden. Die beiden Trägerlaschen 3, 4 sind bezüglich einer Symmetrieebene S asymmetrisch angeordnet. Die Symmetrieebene S erstreckt sich rechtwinklig zu einer Geraden G, welche die beiden parallelen Schwenkachsen A1, A2 verbindet. Darüber hinaus verläuft die Symmetrieebene S parallel zu den Schwenkachsen A1, A2 und liegt hier mittig zwischen den beiden Schwenkachsen A1, A2. Das heisst, der besagte grössere Materialanteil 11 der einen Trägerlasche 2 ist hier bezüglich der Symmetrieebene S asymmetrisch zum Materialanteil der anderen Trägerlasche 4 ausgebildet.With regard to the asymmetry of the two carrier straps 3, 4, the following can be said. The two carrier straps 3, 4 are arranged asymmetrically with respect to a plane of symmetry S. The plane of symmetry S extends at right angles to a straight line G which connects the two parallel pivot axes A1, A2. In addition, the plane of symmetry S runs parallel to the pivot axes A1, A2 and is here centrally between the two pivot axes A1, A2. This means that said larger portion of material 11 of one carrier strap 2 is designed asymmetrically with respect to the material portion of the other carrier strap 4 with respect to the plane of symmetry S.

Bezüglich einer Symmetrieebene U könnte man auch sagen, dass die Trägerlasche 3 bezüglich der anderen Trägerlasche 4 asymmetrisch zur Symmetrieebene U ausgebildet ist, welche rechtwinklig zu den beiden Schwenkachsen A1, A2 mittig durch die Trägerlasche 4 ohne den grösseren Materialanteil verläuft. Diese Symmetrieebene trägt das Bezugszeichen U. Alternativerweise könnte die Symmetrieebene auch durch die beiden Schwenkachsen verlaufen, wobei die Symmetrieebene dann das Bezugszeichen T trägt.With regard to a plane of symmetry U, one could also say that the carrier strap 3 is designed asymmetrically with respect to the other carrier strap 4 with respect to the plane of symmetry U, which runs at right angles to the two pivot axes A1, A2 through the center of the carrier strap 4 without the larger proportion of material. This plane of symmetry bears the reference symbol U. Alternatively, the plane of symmetry could also run through the two pivot axes, the plane of symmetry then bearing the reference symbol T.

Die Definition der Symmetrie kann auch über entsprechende Symmetrieachsen erfolgen.The symmetry can also be defined via corresponding symmetry axes.

In den Figuren 5 und 6 wird eine weitere Ausführungsform der Trägerlaschen 3, 4 mit dem grösseren Materialanteil 11 gezeigt. Hier ist der grössere Materialanteil 11 an einer Aussenfläche 12 der Trägerlasche 3 angeordnet. Dies wird durch die schraffierten Bereiche gezeigt. Der grössere Materialanteil 11 ergänzt sozusagen die Aussenfläche 12 nach aussen hin. Die Aussenfläche 12 ist hier parallel zu den Schwenkachsen A1, A2 orientiert. In der Variante nach der Figur 5 ist eine Sollbruchstelle 16 vorgesehen, wobei sich ein weiterer grösserer Materialanteil 28 dem besagten grösseren Materialanteil anschliesst und sich auch um die andere Trägerlasche 4 ohne den grösseren Materialanteil 11 herum erstreckt. Durch die Ausbildung des Materialanteils 28, welcher sich nur abschnittsweise um die Trägeröffnung herum erstreckt, kann eine Sollbruchstelle 16 geschaffen werden. In der Summe ist der Materialanteil bei der Trägerlasche 3 aber immer grösser als bei der Trägerlasche 3. In der Variante nach der Figur 6 sind zwei Sollbruchstellen 16 vorgesehen.In the Figures 5 and 6 a further embodiment of the carrier straps 3, 4 with the larger proportion of material 11 is shown. Here the larger portion of material 11 is arranged on an outer surface 12 of the carrier strap 3 . This is shown by the shaded areas. The larger portion of material 11 complements the outer surface 12 to the outside, so to speak. The outer surface 12 is oriented here parallel to the pivot axes A1, A2. In the variant after the figure 5 a predetermined breaking point 16 is provided, with a further, larger material portion 28 adjoining said larger material portion and also extending around the other carrier flap 4 without the larger material portion 11. A predetermined breaking point 16 can be created by the design of the material portion 28, which only partially extends around the carrier opening. In total, however, the proportion of material in the carrier strap 3 is always greater than in the carrier strap 3. In the variant according to FIG figure 6 two predetermined breaking points 16 are provided.

Bezüglich der Asymmetrie kann zu den Figuren 5 und 6 gesagt werden, dass die Trägerlasche 3 bezüglich einer Symmetrieachse X, welche zwischen den beiden Trägerlaschen 3, 4 ist, asymmetrisch ist. Die Symmetrieachse X erstreckt sich dabei rechtwinklig zu einer der beiden Schwenkachsen A1, A2 verbindende Gerade, wobei die Symmetrieachse X vorzugsweise mittig zwischen den beiden Schwenkachsen A1, A2 liegt. Die Symmetrieachse kann aber auch rechtwinklig zu den und durch die beiden Schwenkachsen A1, A2 verlaufen.Regarding the asymmetry, the Figures 5 and 6 be said that the support tab 3 is asymmetrical with respect to an axis of symmetry X which is between the two support tabs 3,4. The axis of symmetry X extends at right angles to a straight line connecting the two pivot axes A1, A2, with the axis of symmetry X preferably lying centrally between the two pivot axes A1, A2. However, the axis of symmetry can also run at right angles to and through the two pivot axes A1, A2.

Sowohl die Trägerlasche 2 gemäss den Figuren 2 und 3 als auch die Trägerlasche 2 gemäss den Figuren 5 und 6 umfasst hier eine optionale Sollbruchstelle 16. Die Sollbruchstelle 16 ist dabei als Einkerbung im Bereich des Übergangs zu der Verbindungslasche 18 ausgebildet. Auf diese Sollbruchstelle 18 kann aber auch verzichtet werden.Both the carrier tab 2 according to the Figures 2 and 3 and the carrier flap 2 according to the Figures 5 and 6 here includes an optional predetermined breaking point 16. The predetermined breaking point 16 is designed as a notch in the area of the transition to the connecting strap 18. However, this predetermined breaking point 18 can also be dispensed with.

Wie aus Figur 7 hervorgeht, verfügt die Pressvorrichtung 1 in Form einer Pressschlinge über zwei Presselemente 7, 8 als auch über ein Trägerelement 2 in der Gestalt eines Schlingenteils, mit welchem die Presskraft auf einen Pressling aufbringbar ist. Dabei erstrecken sich zwei Bolzen 9, 10 parallel zueinander durch die beiden Trägeröffnungen 5, 6 bzw. Lageröffnungen 14, 15 des Trägerelements 2 bzw. der Presselemente 7, 8 hindurch, so dass die beiden Schwenkachsen A1, A2 ebenfalls parallel zueinander zu liegen kommen. Das Trägerelement 2 weist auch hier zwei Trägerlaschen 3, 4 auf, wobei die Trägerlasche 3 mit dem grösseren Materialanteil 11 ausgebildet ist. Die Trägerlasche 4 ist ohne dem grösseren Materialanteil 11 ausgebildet.How out figure 7 shows that the pressing device 1 in the form of a pressing sling has two pressing elements 7, 8 and a carrier element 2 in the form of a sling part with which the pressing force can be applied to a compact. Two bolts 9, 10 extend parallel to one another through the two carrier openings 5, 6 or bearing openings 14, 15 of the carrier element 2 or the pressing elements 7, 8, so that the two pivot axes A1, A2 also come to lie parallel to one another. Here, too, the carrier element 2 has two carrier straps 3 , 4 , the carrier strap 3 being formed with the larger proportion of material 11 . The carrier strap 4 is formed without the larger proportion of material 11 .

Die Presselemente 7, 8 sowie das Trägerelement 2 weisen jeweils eine Pressbackenaufnahme 22 mit einer Aufnahmefläche auf, in welche die Pressbacken 20 eingearbeitet sind. Die Presselemente 7, 8 in Form der Schlingenteile sind jeweils an einem Ende über die Bolzen durchgängig mit dem Trägerelement 2 verbunden, während jeweils das andere Ende ein unverbundenes, freies Ende ist, zwischen welchen freien Enden ein Abstand zur Ausbildung einer Schliessstelle vorgesehen ist. Am Ende des Pressvorganges befinden sich diese beiden freien Enden in einem minimalen Abstand zueinander und die Pressschlinge weist dann einen im Wesentlichen zylindrischen Querschnitt auf. An den freien Enden der Pressschlinge, d.h. an der Schliessstelle, befinden sich Verbindungsbolzen 23 sowie Nuten 24, an welche eine Zwischenbacke, wie beispielsweise in Figur 8 dargestellt, angesetzt werden kann. Der erhöhte Materialanteil könnte auch im Bereich der freien Enden und der Bolzenverbindung sein.The pressing elements 7, 8 and the carrier element 2 each have a pressing jaw receptacle 22 with a Recording surface, in which the pressing jaws 20 are incorporated. The pressing elements 7, 8 in the form of the loop parts are each connected continuously at one end via the bolts to the carrier element 2, while the other end is an unconnected, free end, between which free ends there is a distance to form a closing point. At the end of the pressing process, these two free ends are at a minimal distance from one another and the press sling then has an essentially cylindrical cross section. At the free ends of the press sling, ie at the closing point, there are connecting bolts 23 and grooves 24, to which an intermediate jaw, such as in figure 8 shown, can be applied. The increased material content could also be in the area of the free ends and the bolt connection.

In Figur 8 ist eine Pressvorrichtung 1 aufweisend ein Trägerelement 2 mit zwei Trägeröffnungen 5, 6 und einem Presselement in Form einer Zwischenbacke mit zwei Lageröffnungen gezeigt. Ein Bolzen 9, 10 erstreckt sich jeweils durch eine der Trägeröffnungen 5, 6 und der Lageröffnungen 14, 15 hindurch. Die Zwischenbacke ist mit zwei Backenhebeln 25 ausgebildet, welche an ihrem einen Ende in eine Kralle 26 münden. Diese Kralle 26 lässt sich in Nuten 27 einer Pressschlinge wie beispielsweise in Figur 7 gezeigt einführen und in deren Verbindungsbolzen 23 einhängen. In der verbundenen Position umgreift die Kralle 26 die Verbindungsbolzen 23 der Pressschlinge vollständig. Indem die Backenhebel 25 dann aufeinander zu bewegt werden, werden die freien Enden der Pressschlinge ebenfalls aufeinander zu bewegt und es erfolgt ein Verpressen des von der Pressschlinge umschlungenen Presslings. Die Backenhebel 25 sind dazu analog zu den Presshebeln über jeweils eine Schwenkachse A1, A2 schwenkbar am Trägerelement 2 gelagert und so von der Ausgangslage, in welcher noch keine Verpressung des Presslings erfolgte, in die Presslage, in welcher der Pressling verpresst wird, verschwenkbar.In figure 8 shows a pressing device 1 having a carrier element 2 with two carrier openings 5, 6 and a pressing element in the form of an intermediate jaw with two bearing openings. A bolt 9, 10 extends through one of the support openings 5, 6 and the bearing openings 14, 15 respectively. The intermediate jaw is formed with two jaw levers 25 which open into a claw 26 at one end. This claw 26 can be inserted into grooves 27 of a press sling such as in figure 7 insert shown and hang in their connecting bolts 23. In the connected position, the claw 26 completely encompasses the connecting bolts 23 of the press sling. As the jaw levers 25 are then moved towards one another, the free ends of the press sling are also moved towards one another and the compact wrapped around by the press sling is pressed. For this purpose, the jaw levers 25 are pivotably mounted on the carrier element 2 via a pivot axis A1, A2 in each case, analogously to the pressing levers, and can thus be pivoted from the initial position, in which the compact has not yet been pressed, into the pressed position in which the compact is pressed.

Die Trägerlasche 3 des Trägerelementes 2 ist hier wiederum mit einem grösseren Materialanteil 11 versehen. Die Trägerlasche 4 weist keinen grösseren Materialanteil auf. Bezüglich der Anordnung des grösseren Materialanteils wird auf die obige Beschreibung im Zusammenhang mit den Figuren 1 bis 6 verwiesen.The carrier flap 3 of the carrier element 2 is here again provided with a larger proportion of material 11 . The carrier flap 4 does not have a large proportion of material. Regarding the arrangement of the larger proportion of material is on the above description in connection with the Figures 1 to 6 referred.
