Abstract

An apparatus for compressing objects includes a base plate, a frame and a ram head guided so as to be displaceable on the frame. Forces may occur in the peripheral direction of the ram head during the compression of bulky objects. The ram head is rotatable relative to the frame in order to reduce the forces introduced into the frame.

Description

Die vorliegende Erfindung betrifft eine Vorrichtung und eine hydraulische Hochdruckpresse zum Komprimieren von Gegenständen mit einer Bodenplatte, einem Gestell und einem an dem Gestell verschieblich geführten Stempelkopf.The present invention relates to a device and a hydraulic high pressure press for compressing objects with a base plate, a frame and one on the frame slidably guided stamp head.

Derartige Vorrichtungen sind in unterschiedlichen Ausgestaltungen bekannt geworden (siehe US-A-4 610 199) und sind zum Komprimieren vielerlei Arten von Gegenständen geeignet. Bekannt sind beispielsweise Vorrichtungen leichterer Bauart für eng begrenzte und geringe Druckkraftanforderungen, die im wesentlichen als Schraubzwinge ausgebildet sind (GB-A-1513367). Zum Komprimieren von mit Abfall gefüllten Knautschtrommeln geeignete Vorrichtungen müssen jedoch hohen Auslegungskriterien bezüglich Druckkraft und Konstruktion genügen. Vor allem kann es sich dabei auch um radioaktiv oder anderweitig kontaminierten Abfall handeln, der in Fässern oder anderen geeigneten Gefäßen eingeschlossen ist.Such devices are in different configurations have become known (see US-A-4 610 199) and are various for compressing Suitable types of objects. Are known, for example Lighter design devices for narrow and small Pressure force requirements, essentially as a screw clamp are formed (GB-A-1513367). To compress with Suitable devices for waste-filled crumple drums however, must meet high design criteria with regard to compressive force and construction are sufficient. Above all, it can are radioactive or otherwise contaminated waste, enclosed in barrels or other suitable containers is.

Während des Preßvorgangs zum Komprimieren können in Umfangsrichtung wirkende Kräfte auf den Stempelkopf aufgebracht werden. Diese Kräfte werden durch sperrige Teile (z.B. Stahlrohre) in der Knautschtrommel erzeugt und in das Gestell der Vorrichtung eingeleitet. Bei den bekannten Vorrichtungen muß daher das Gestell entsprechend ausgelegt und größer dimensioniert werden, so daß höhere Konstruktionskosten entstehen. Trotz dieser aufwendigen Konstruktion kann eine Beschädigung durch die in Umfangsrichtung wirkenden Kräfte nicht ausgeschlossen werden. Insbesondere sperrige Stahlteile oder rohrförmige Teile können nämlich erhebliche Kräfte in Umfangsrichtung umleiten. During the pressing process for compressing can be done in the circumferential direction acting forces are applied to the stamp head. These forces are caused by bulky parts (e.g. steel pipes) produced in the crumple drum and in the frame of the Device initiated. In the known devices must therefore the frame is designed accordingly and dimensioned larger be, so that higher construction costs arise. Despite this complex construction, damage can occur not excluded by the forces acting in the circumferential direction become. In particular bulky steel parts or tubular ones Parts can namely considerable forces in the circumferential direction redirect.

Aufgabe der vorliegenden Erfindung ist es daher, die von dem Stempelkopf in das Gestell eingeleiteten Kräfte zu verringern.The object of the present invention is therefore that of Reduce stamp head forces introduced into the frame.

Erfindungsgemäß wird diese Aufgabe bei einer Vorrichtung zum Komprimieren von Gegenständen mit einer Bodenplatte, einem Gestell und einem an dem Gestell verschieblich geführten Stempel mit einem am Stempel angebrachten Stempelkopf, der gegenüber dem Gestell drehbar ist, dadurch gelöst, daß der Stempelkopf einen mittig angeordneten Bolzen aufweist, der an einem Ende drehbar mit dem Stempel verbunden ist, so daß der Stempelkopf drehbar am Stempel gelagert ist, und daß der Bolzen an einem anderen Ende mit einem Gewindeansatz zur drehfesten Befestigung an dem Stempelkopf versehen ist, so daß der Stempelkopf auswechselbar ist.According to the invention, this object is achieved in a device for Compress objects with a bottom plate, one Frame and a slidably guided on the frame Stamp with a stamp head attached to the stamp, the is rotatable relative to the frame, in that the Stamp head has a centrally located bolt on one end is rotatably connected to the stamp, so that the Stamp head is rotatably mounted on the stamp, and that the bolt at another end with a thread for non-rotatable Attachment to the stamp head is provided so that the stamp head is replaceable.

Sobald beim Komprimieren sperrige Teile verkeilt werden und eine Kraft in Umfangsrichtung erzeugen, wird der Stempelkopf gegenüber dem Gestell und damit gegenüber der Bodenplatte verdreht. Hierdurch kommen die eingeklemmten sperrigen Teile frei, so daß keine Kraft mehr in Umfangsrichtung wirkt. Die drehbare Lagerung des Stempelkopfes verhindert das Einleiten von in Umfangsrichtung wirkenden Kräften in das Gestell, das daher auf geringere Belastungen ausgelegt werden kann.As soon as bulky parts are wedged during compression and generate a force in the circumferential direction, the stamp head opposite the frame and thus against the base plate twisted. This will result in the jammed bulky parts free, so that no more force acts in the circumferential direction. The rotatable mounting of the stamp head prevents the discharge of forces acting in the circumferential direction in the frame, the can therefore be designed for lower loads.

Die Vorrichtung weist also einen Stempel auf, an dem der Stempelkopf drehbar gelagert ist. Der Stempel dient zum Aufbringen der nötigen Kraft auf den Stempelkopf. Durch die Trennung zwischen Stempel und Stempelkopf können bekannte Vorrichtungen nachgerüstet werden. Weiter ist ein Auswechseln des Stempelkopfes möglich.The device thus has a stamp on which the Stamp head is rotatably mounted. The stamp is used for application the necessary force on the stamp head. Through the Separation between stamp and stamp head can be known Devices can be retrofitted. Another is a replacement of the stamp head possible.

Desweiteren weist also der Stempelkopf einen mittig angeordneten Bolzen auf, der drehbar mit dem Stempel verbunden ist. Das Gewicht des Stempelkopfes wird durch den Bolzen getragen, der einfach und mit geringem Aufwand drehbar an dem Stempel gelagert ist. Furthermore, the stamp head has a centrally arranged one Bolt on, which is rotatably connected to the stamp. The weight of the stamp head is borne by the bolt, which can be easily rotated on the stamp with little effort is stored.

Außerdem ist der Bolzen also an einem Ende mit einem Gewindeansatz zur drehfesten Befestigung an dem Stempelkopf versehen. Der Gewindeansatz ermöglicht eine rasche und einfache Befestigung sowie einen raschen Austausch des Bolzens.In addition, the bolt is threaded at one end provided for non-rotatable attachment to the stamp head. The thread approach enables quick and easy Attachment as well as a quick exchange of the bolt.

Vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung gehen aus den abhängigen Ansprüchen hervor.Advantageous refinements and developments of the invention emerge from the dependent claims.

Nach einer vorteilhaften Ausgestaltung ist der Bolzen mit einer Vorspannung beaufschlagt. Die Vorspannung wird vorteilhaft etwas größer gewählt als die Gewichtskraft des Stempelkopfes. Der Stempelkopf wird somit in jeder Position in einer definierten Lage an dem Stempel gehalten und legt sich nicht erst beim Komprimieren an den Stempel an. Beschädigungen im Bereich der Berührflächen zwischen Stempel und Stempelkopf werden hierdurch zuverlässig vermieden.According to an advantageous embodiment, the bolt is with a Preload applied. The bias becomes advantageous chosen slightly larger than the weight of the stamp head. The stamp head is in one position in every position defined position held on the stamp and does not lie down only when compressing the stamp. Damages in the Area of contact between the stamp and stamp head are reliably avoided.

In vorteilhafter Weiterbildung ist das andere Ende des Bolzens über eine Scheibe und Schraubbolzen an dem Stempel abgestützt. Dieses andere Ende des Bolzens ist drehbar mit dem Stempel verbunden. Die Abstützung über die Scheibe und die Schraubbolzen ermöglicht eine einfache und kostengünstige Konstruktion ohne spezielle Lagerungen.In an advantageous development, the other end of the bolt supported by a washer and bolts on the stamp. This other end of the pin is rotatable with the Stamp connected. The support over the disc and the Bolt allows easy and inexpensive Construction without special bearings.

Gemäß einer vorteilhaften Ausgestaltung ist der Bolzen gegenüber der Scheibe drehbar. Eine Relativbewegung zwischen den Schraubbolzen und der Scheibe sowie der Scheibe und dem Stempel findet nicht statt. Verschleiß auf Grund einer Drehung des Stempelkopfs gegenüber dem Stempel liegt daher nur im Bereich der Scheibe und des Bolzens vor, die beide leicht gewechselt werden können.According to an advantageous embodiment, the bolt is opposite the disc rotates. A relative movement between the Bolt and the washer as well as the washer and the stamp does not take place. Wear due to rotation the stamp head compared to the stamp is therefore only in the area the washer and the bolt in front, both easily changed can be.

Vorteilhaft stützen sich die Schraubbolzen an einer auf dem Stempel aufliegenden Scheibe ab. Sobald in Einzelfällen eine Bewegung der Schraubbolzen gegenüber dem Stempel auftritt, liegt kein direkter Kontakt zwischen den Schraubbolzen und dem Stempel vor. Beschädigungen können nur an den Schraubbolzen und der Scheibe auftreten, die rasch und einfach gewechselt werden können.The bolts are advantageously supported on one of the Stamp on the disc. As soon as in individual cases Movement of the bolts against the punch occurs there is no direct contact between the bolts and before the stamp. Damage can only be caused to the screw bolts and the disc occur, which can be changed quickly and easily can be.

Nach einer vorteilhaften Weiterbildung greifen die Schraubbolzen zum Abstützen des Stempelkopfes in eine umlaufende Nut ein. Diese umlaufende Nut bewirkt eine seitliche Führung der Schraubbolzen und damit eine Fixierung des Stempelkopfes.According to an advantageous development, the bolts engage to support the stamp head in a circumferential groove on. This circumferential groove causes lateral guidance of the Screw bolts and thus a fixation of the stamp head.

In vorteilhafter Ausgestaltung sind die Schraubbolzen über Tellerfedern vorgespannt. Tellerfedern ermöglichen große Vorspannkräfte bei geringem Platzbedarf und geringen Kosten. Die Vorspannkraft kann durch ein Auswechseln der Tellerfedern rasch und einfach ohne aufwendige Maßnahmen verändert werden.In an advantageous embodiment, the bolts are over Bias springs preloaded. Disc springs allow large preload forces with a small footprint and low costs. The Preload can be changed by replacing the disc springs can be changed quickly and easily without complex measures.

Vorteilhaft sind der Stempel und der Stempelkopf über einen Ansatz zueinander zentriert. Hierdurch wird eine definierte Lage des Stempelkopfes gegenüber dem Gestell in jeder Drehposition sichergestellt. Der Ansatz nimmt gleichzeitig eventuell entstehende Querkräfte auf und entlastet den Bolzen, der den Stempelkopf mit dem Stempel verbindet.The stamp and the stamp head are advantageous over one Centered approach to each other. This creates a defined Position of the stamp head in relation to the frame in any rotational position ensured. The approach may take a while arising transverse forces and relieves the bolt that connects the stamp head to the stamp.

Vorteilhaft ist der Stempel mit dem Stempelkopf hydraulisch im wesentlichen in vertikaler Richtung bewegbar, wobei lediglich der Stempelkopf gegenüber dem Gestell drehbar ist. D.h. also, daß der Stempel mit dem Stempelkopf auf- und abbewegbar ist - beispielsweise durch eine entsprechende Hydraulikvorrichtung. Dabei ist der Stempel in der Regel nicht drehbar, sondern nur der Stempelkopf.The stamp with the stamp head is advantageously hydraulic essentially movable in the vertical direction, only the stamp head is rotatable relative to the frame. That that is, the stamp can be moved up and down with the stamp head is - for example, by a corresponding hydraulic device. The stamp is usually not rotatable, just the stamp head.

Erfindungsgemäß wird obige Aufgabe bei einer Hochdruckpresse - insbesondere bei einer hydraulischen Hochdruckpresse - zum Komprimieren von Gegenständen, insbesondere zum Komprimieren von sperrige Teile beinhaltenden Gefäßen, mit einer Bodenplatte, einem Gestell und einem an dem Gestell verschieblich geführten Stempel, wobei am Stempel ein Stempelkopf angebracht ist, der gegenüber dem Gestell drehbar ist, dadurch gelöst, daß der Stempelkopf einen mittig angeordneten Bolzen aufweist, der an einem Ende drehbar mit dem Stempel verbunden ist, so daß der Stempelkopf drehbar am Stempel gelagert ist. Da eine Hochdruckpresse, insbesondere eine hydraulische Hochdruckpresse, Druckkräfte von einigen tausend Tonnen erzeugen kann, insbesondere etwa im Bereich von 2000 t ist es möglich, daß beim Komprimieren sperriger Teile diese verkeilt werden und Kräfte in Umfangsrichtung erzeugen, die im Bereich einiger Tonnen bis zu einigen hundert Tonnen, insbesondere im Bereich von 50 bis 200 t liegen. Sobald derartig sperrige Teile verkeilt werden, wird der Stempelkopf gegenüber dem Gestell und damit gegenüber der Bodenplatte verdreht, so daß die eingeklemmten sperrigen Teile frei werden und die Kräfte in Umfangsrichtung erheblich verringert werden. Insbesondere in dem Bereich der beispielhaft genannten Druckkraftbeanspruchung einer solchen Hochdruckpresse und den damit verbundenen möglichen beispielhaft genannten Kräften in Umfangsrichtung ergibt die genannte Lösung der Aufgabe gemäß der Erfindung erhebliche Vorteile bei der konstruktiven Auslegung einer solchen Hochdruckpresse als auch bei der Durchführung eines Pressvorgangs mit solch einer Hochdruckpresse.According to the invention, the above object is achieved with a high-pressure press - especially in a hydraulic high-pressure press - for Compressing objects, especially for compressing of vessels containing bulky parts, with a base plate, one frame and one slidable on the frame guided stamp, with a stamp head on the stamp attached, which is rotatable relative to the frame, solved in that the stamp head has a centrally arranged bolt, which is rotatably connected to the stamp at one end is so that the stamp head is rotatably mounted on the stamp. Since a high pressure press, especially a hydraulic high pressure press, Generate compressive forces of a few thousand tons can, especially in the range of about 2000 t, it is possible that when compressing bulky parts they are wedged and generate circumferential forces in the range of some Tons up to a few hundred tons, especially in the area from 50 to 200 t. As soon as such bulky parts be wedged, the stamp head is opposite the frame and thus rotated relative to the base plate, so that the clamped bulky parts become free and the forces in the circumferential direction be significantly reduced. Especially in the area of the compressive force loading mentioned by way of example such a high pressure press and the associated possible exemplary forces in the circumferential direction gives the stated solution of the object according to the invention considerable advantages in the design of a such high pressure press as well as when carrying out a Pressing process with such a high pressure press.

Eine weitere vorteilhafte Ausgestaltung sieht bei der genannten Hochdruckpresse, insbesondere bei einer hydraulischen Hochdruckpresse, vor, daß der Bolzen an einem anderen Ende mit einem Gewindesatz zur drehfesten Befestigung an dem Stempelkopf versehen ist, so daß der Stempelkopf auswechselbar ist. Denn insbesondere bei hoher Druckkraftbeanspruchung bei einer Hochdruckpresse ist es besonders vorteilhaft, wenn nach einem möglichen Verschleiß eines Stempelkopfes dieser auswechselbar ist. Dies hat insbesondere den Vorteil, daß dazu nicht der gesamte Stempel ausgewechselt werden oder mit erheblichem Aufwand ausgebaut und wieder eingebaut werden müßte, um einen neuen Stempelkopf anzubringen. Dagegen ist ein gemäß der Erfindung verschraubter Stempelkopf leicht vom Stempel lösbar und damit auswechselbar. A further advantageous embodiment is seen in the above High pressure press, especially in a hydraulic one High pressure press, before that the bolt at another end with a set of threads for non-rotatable attachment to the stamp head is provided so that the stamp head can be replaced is. Because especially with high pressure loads a high pressure press, it is particularly advantageous if after a possible wear of a stamp head can be replaced is. This has the particular advantage that not the entire stamp can be replaced or with significant Effort would have to be expanded and reinstalled, to attach a new stamp head. Against is a according to the invention screwed stamp head slightly from Removable stamp and therefore exchangeable.

Nachstehend wird die Erfindung an Hand eines Ausführungsbeispieles näher beschrieben, das in schematischer Weise in der Zeichnung dargestellt ist. Dabei zeigt:

The invention is described in more detail below with the aid of an exemplary embodiment which is shown in a schematic manner in the drawing. It shows:
Figure 1
a schematic view of a device or high pressure press according to the invention; and
Figure 2
an enlarged view of the attachment of the stamp head to the stamp in said device or high-pressure press.

Die in Figur 1 dargestellte erfindungsgemäße Vorrichtung 10 umfaßt eine Bodenplatte 11, ein Gestell 12, einen Stempel 13 und einen Stempelkopf 14. Es ist weiter ein Halter 15 vorgesehen, in dessen Innenraum 20 eine Tonne 16 eingesetzt ist. Der Stempelkopf 14 ist in Pfeilrichtung 18 gegenüber dem Gestell verschieblich geführt. Zur Bewegung dient der Stempel 13, der geeignete, nicht näher dargestellte Einrichtungen enthält. Beim Komprimieren der Tonne 16 können in der Tonne 16 enthaltene sperrige Gegenstände Kräfte in Umfangsrichtung auf den Stempelkopf 14 aufbringen. Dieser Umstand ergibt sich im wesentlichen aufgrund der durch die sperrigen Teile bewirkte nichtzentrische Einleitung der Druckkraft auf dem zum komprimierenden Gegenstand (z. b. ein Fass, welches solche Gegenstände enthalten kann).The device 10 according to the invention shown in FIG. 1 comprises a base plate 11, a frame 12, a stamp 13 and a stamp head 14. A holder 15 is also provided, in the interior 20 a barrel 16 is inserted. The stamp head 14 is in the direction of arrow 18 opposite the frame slidably guided. The stamp is used for movement 13, the suitable facilities, not shown contains. When compressing the bin 16 can in the bin 16 contained bulky objects forces in the circumferential direction apply to the stamp head 14. This fact arises essentially due to the bulky parts non-centric introduction of the pressure force on the to compressing object (e.g. a barrel containing such May contain items).

Bei einer Hochdruckpresse, insbesondere einer hydraulischen Hochdruckpresse, werden Druckkräfte im Bereich einiger tausend Tonnen - vornehmlich im Bereich um etwa 2000 t - auf einen zu komprimierenden Gegenstand aufgebracht. Dies kann zur Folge haben, daß Kräfte in Umfangrichtung von einer Tonne bis zu einigen hundert Tonnen entstehen. Der Stempelkopf 14 ist daher um seine Mittelachse 17 in Pfeilrichtung 19 drehbar an dem Stempel 13 gelagert. Hierdurch ist der Stempelkopf 14 gegenüber dem Gestell 12 drehbar. Insbesondere bei einer hydraulischen Hochdruckpresse werden so mögliche in Umfangsrichtung wirkende Kräfte erheblich verringert. In a high pressure press, especially a hydraulic one High pressure press, pressure forces are in the range of a few thousand Tons - primarily in the range of around 2000 t - on one applied object to be compressed. This can lead to Consequence that forces in the circumferential direction from a ton to to create a few hundred tons. The stamp head 14 is therefore rotatable about its central axis 17 in the direction of arrow 19 the stamp 13 stored. As a result, the stamp head 14 is opposite the frame 12 rotatable. Especially with a hydraulic High pressure press are possible in the circumferential direction acting forces significantly reduced.

Figur 2 zeigt Einzelheiten der Verbindung zwischen dem Stempel 13 und dem Stempelkopf 14. Der Stempelkopf 14 weist einen mittig angeordneten Bolzen 21 auf, der mit einem Gewindeansatz 22 zur drehfesten Befestigung an dem Stempelkopf 14 versehen ist. Am anderen Ende des Bolzens 21 ist eine Scheibe 24 angeordnet, die über einen Ring 25 drehbar, aber axial fixiert mit dem Bolzen 21 verbunden ist. An der Scheibe 24 sind mehrere gleichmäßig über den Umfang verteilte Schraubbolzen 28 angeordnet. Die Schraubbolzen 28 stützen sich in einer umlaufenden Nut 30 einer weiteren Scheibe 23 ab. Diese Scheibe 23 liegt auf dem Stempel 13 auf.Figure 2 shows details of the connection between the stamp 13 and the stamp head 14. The stamp head 14 has one centrally arranged bolt 21 on the with a threaded approach 22 for rotationally fixed attachment to the stamp head 14 is. At the other end of the bolt 21 is a washer 24 arranged, which is rotatable via a ring 25, but axially fixed is connected to the bolt 21. Are on the disc 24 several bolts distributed evenly over the circumference 28 arranged. The bolts 28 are supported in a circumferential Groove 30 from a further disk 23. That disc 23 rests on the stamp 13.

Sobald beim Komprimieren eine Kraft in Umfangsrichtung des Stempelkopfes 14 entsteht, wird dieser zusammen mit dem Bolzen 21 verdreht. Die Scheibe 24 und die Schraubbolzen 28 bewegen sich im Idealfall nicht. Sollte wider Erwarten eine Drehbewegung der Scheibe 24 in Pfeilrichtung 19 auftreten, werden die Schraubbolzen 28 durch die umlaufende Nut 30 zuverlässig geführt. In jedem Fall ist eine Drehung des Stempelkopfes 14 in Pfeilrichtung 19 um seine Mittelachse 17 möglich. Ein Verschleiß des Stempels 13 oder des Stempelkopfes 14 wird zuverlässig durch die Scheiben 23, 24 und die Schraubbolzen 28 vermieden.As soon as a force in the circumferential direction of the Stamp head 14 arises, this is together with the bolt 21 twisted. Move the washer 24 and the bolts 28 ideally not. Should be contrary to expectations Rotary movement of the disk 24 occur in the direction of arrow 19 the bolts 28 are reliable due to the circumferential groove 30 guided. In any case there is a rotation of the stamp head 14 possible in the direction of arrow 19 about its central axis 17. Wear of the stamp 13 or the stamp head 14 is reliably by the discs 23, 24 and Avoided bolts 28.

Die Schraubbolzen 28 können über tellerfedern 29 vorgespannt werden. Diese Vorspannung beaufschlagt den Bolzen 21 und wird größer als die Gewichtskraft des Stempelkopfes 14 gewählt. In Figur 2 ist dargestellt, daß der Stempelkopf 14 durch die Vorspannung auf Grund der Tellerfedern 29 von unten gegen den Stempel 13 gedrückt wird. Der Stempelkopf 14 befindet sich somit stets in genau definierter Position gegenüber dem Stempel 13. Beschädigungen des Stempels 13 oder des Stempelkopfes 14 während des Komprimierens sind daher ausgeschlossen.The bolts 28 can be prestressed via plate springs 29 become. This bias acts on the bolt 21 and is selected greater than the weight of the stamp head 14. In Figure 2 shows that the stamp head 14 by the Preload due to the plate springs 29 from below against the Stamp 13 is pressed. The stamp head 14 is located thus always in a precisely defined position in relation to the stamp 13. Damage to the stamp 13 or the stamp head 14 during compression are therefore excluded.

Zur Zentrierung zwischen Stempel 13 und Stempelkopf 14 dient ein Ansatz 27 am Stempelkopf 14. Der Ansatz nimmt eine Kante 26 am Stempel 13 auf. Der Ansatz 27 nimmt gegebenenfalls beim Komprimieren auftretende Querkräfte auf und entlastet hierdurch den Bolzen 21. Die zum Komprimieren erforderliche Kraft wird über eine Berührfläche 32 zwischen dem Stempel 13 und dem Stempelkopf 14 aufgebracht. Seitlich des Ansatzes 27 ist zwischen dem Stempel 13 und dem Stempelkopf 14 ein Zwischenraum 31 vorgesehen. Dieser Zwischenraum 31 verringert die Berührfläche 32 zwischen Stempel 13 und Stempelkopf 14. Hierdurch wird die zu bearbeitende Fläche verringert, so daß geringere Herstellungskosten entstehen. Auch die zum Verdrehen des Stempelkopfes 14 in Pfeilrichtung 19 erforderliche Kraft wird verringert, so daß nur sehr kleine Kräfte in Umfangsrichtung in das Gestell 12 eingeleitet werden.For centering between the stamp 13 and stamp head 14 is used a shoulder 27 on the stamp head 14. The shoulder takes an edge 26 on the stamp 13. Approach 27 takes, if necessary Compress occurring transverse forces and thereby relieves the bolt 21. The force required for compression is over a contact surface 32 between the stamp 13 and applied to the stamp head 14. The side of the approach is 27 a space between the stamp 13 and the stamp head 14 31 provided. This space 31 reduces the contact area 32 between stamp 13 and stamp head 14 the area to be worked is reduced so that less Manufacturing costs arise. Even those to twist of the stamp head 14 in the direction of arrow 19 required force is reduced so that only very small forces in the circumferential direction be introduced into the frame 12.

Durch die Drehbarkeit des Stempelkopfes 14 gegenüber dem Gestell 12 werden die in das Gestell 12 eingeleiteten Kräfte wesentlich verringert und im Idealfall vollständig abgebaut. Das Gestell 12 kann daher auf geringere Belastungen ausgelegt werden.Due to the rotatability of the stamp head 14 relative to the frame 12 are the forces introduced into the frame 12 significantly reduced and ideally completely dismantled. The frame 12 can therefore be designed for lower loads become.
