Description

1. Gebiet der Erfindung1. Field of the invention

Die Erfindung betrifft eine Strang- und Rohrpresse gemäß dem Oberbegriff des Anspruchs 1 (siehe z.B. US-A-3,220,237 ). Des Weiteren betrifft die Erfindung ein Verfahren zum Abtrennen eines Pressrests beim Strang- und Rohrpressen unter Verwendung einer derartigen Strang- und Rohrpresse.The invention relates to an extrusion and pipe press according to the preamble of claim 1 (see e.g. US-A-3,220,237 ). The invention further relates to a method for separating off a press residue during extrusion and pipe pressing using such an extrusion and pipe press.

2. Stand der Technik2. State of the art

Eine weitere Strang- und Rohrpresse bzw. Metallstrangpresse ist aus der EP 1 750 865 B1 bekannt und durch die DE 102 31 328 A1 ist eine Trennschere mit einem speziellen, zwei Schneidflächen aufweisenden Messer bekannt geworden, wobei die Trennvorrichtung mittels eines Zylinders um eine drehbare Lagerung verschwenkbar ausgebildet ist, damit sich ein glatter, sauberer Trennschnitt erreichen lässt, ggf. auch bei einem aus dem Blockaufnehmer bzw. Rezipienten herausragenden Ende des zu verpressenden Blocks bzw. Metallbolzens.Another extrusion and pipe press or metal extrusion press is from the EP 1 750 865 B1 known and by the DE 102 31 328 A1 a cutting shear with a special knife with two cutting surfaces has become known, the cutting device being designed to be pivotable about a rotatable bearing by means of a cylinder so that a smooth, clean cut can be achieved, possibly also with one protruding from the block receiver or recipient End of the block or metal bolt to be pressed.

Derartige Strang- und Rohrpressen benötigen eine Trenneinrichtung, insbesondere eine Schervorrichtung, um den unvermeidlich beim Strangpressen zurückbleibenden Pressrest, der nach dem Pressvorgang aus dem am oder im Gegenholm angeordneten Werkzeug hervorsteht, abzutrennen, und um das Strang- oder Rohrpressen eines folgenden Blockes bzw. Metallbolzens ungehindert fortsetzen zu können. Dabei wird insbesondere Wert gelegt auf einen sauberen Trennschnitt zum Abtrennen des Pressrests, um den Qualitätsanforderungen an das Strangpressen einer Vielzahl von Blöcken bzw. Metallbolzen zu genügen.Such extrusion and pipe presses require a separating device, in particular a shearing device, in order to separate the pressing residue that inevitably remains during the extrusion process, which protrudes from the tool located on or in the counter beam after the pressing process, and in order to extrude or pipe a subsequent block or metal bolt to be able to continue unhindered. In doing so, particular importance is attached to a clean cut for separating off the press residue, in order to meet the quality requirements for the extrusion of a large number of blocks or metal bolts.

Die Schervorrichtung muss dabei über eine Strecke von üblicherweise mehr als 800 mm aus einer Ruheposition vertikal senkrecht zur Strangpressrichtung bewegt werden, um das Abscheren des Pressrests zu bewirken, und über die gleiche Distanz auch wieder in ihre Ruheposition zurückgeführt werden. Darüber hinaus erfolgt zur Verringerung des Verschleißes zwischen der Trenneinrichtung oder Schervorrichtung und dem Gegenholm oder dem daran angeordneten Werkzeug ein Verschwenken der Schervorrichtung oder zumindest eines daran angeordneten Schermessers oder einer Scherplatte vor dem Zurückfahren der Schervorrichtung in ihre Ruheposition.The shearing device must be moved over a distance of usually more than 800 mm from a rest position vertically perpendicular to the extrusion direction in order to effect the shearing off of the pressed residue, and must also be returned to its rest position over the same distance. In addition, to reduce the wear between the cutting device or shearing device and the counter bar or the tool arranged on it, the shearing device or at least one shearing knife or a shear plate arranged thereon is pivoted before the shearing device is moved back into its rest position.

Hierdurch wird der Bauraum der Vorrichtung jedoch ausgesprochen groß und ihr Aufbau komplex. Sowohl die Mehrzahl von erforderlichen Bewegungen als auch der erforderliche Vertikalhub führen darüber hinaus zu erhöhtem Aufwand und Nebenzeiten, in denen die Strang- und Rohrpresse nicht produzieren kann.However, this makes the installation space of the device extremely large and its structure complex. Both the majority of required movements and the required vertical stroke also lead to increased effort and non-productive times in which the extrusion and pipe press cannot produce.

3. Aufgabe der Erfindung3. Object of the invention

Es war daher eine Aufgabe der Erfindung, eine Strang- oder Rohrpresse zur Verfügung zu stellen, die neben einem äußerst sauberen Trennschnitt mit sehr guter Scherfläche auch verkürzte Nebenzeiten und einen verringerten Bauraum zur Verfügung stellen kann. Diese Aufgabe wird im erfindungsgemäßen Sinne mittels einer Strang- oder Rohrpresse, umfassend die Merkmale des Anspruchs 1, sowie mittels eines Verfahrens, umfassend die Merkmale des Anspruchs 5, gelöst. Vorteilhafte Ausgestaltungen der Erfindung sind in den jeweils abhängigen Ansprüchen niedergelegt.It was therefore an object of the invention to provide an extrusion or pipe press which, in addition to an extremely clean severing cut with a very good shear surface, can also provide shortened non-productive times and reduced installation space. This object is achieved in the sense of the invention by means of an extrusion or pipe press comprising the features of claim 1 and by means of a method comprising the features of claim 5. Advantageous refinements of the invention are set out in the respective dependent claims.

4. Zusammenfassung der Erfindung4. Summary of the invention

Gemäß einem ersten Aspekt der Erfindung ist die Schervorrichtung vertikal und horizontal verschiebbar an dem Pressenrahmen angeordnet, wobei die vertikale Verschiebbarkeit der Trennschere bis oberhalb des Werkzeugs, nicht jedoch bis oberhalb des Blockaufnehmers einstellbar ist. Durch die horizontale und vertikale Verstellbarkeit der Schervorrichtung lässt sich erreichen, dass die Trennvorrichtung bzw. Trennschere in der Ruheposition stets nur bis knapp oberhalb des Werkzeugs, insbesondere der Druckplatte, des Matrizenhalters oder der Matrize, und nicht auch bis oberhalb des Blockaufnehmers (Rezipient) angehoben werden muss. Zum Trennschnitt in der Arbeitsposition braucht das Messer der Schervorrichtung nur über eine geringe Wegstrecke abgesenkt zu werden, wobei sich die Schervorrichtung durch einen vorzugsweise linearen Verfahrantrieb so genau positionieren lässt, dass der Pressrest glatt abgeschert werden kann.According to a first aspect of the invention, the shearing device is arranged vertically and horizontally displaceably on the press frame, the vertical displaceability of the cutting shears being adjustable up to above the tool, but not up to above the block receiver. The horizontal and vertical adjustability of the shearing device means that the cutting device or cutting shears in the rest position is always raised only to just above the tool, in particular the pressure plate, die holder or die, and not also above the block receiver (recipient) must become. For the severing cut in the working position, the knife of the shearing device only needs to be lowered over a short distance, whereby the shearing device can be positioned so precisely by a preferably linear displacement drive that the pressed residue can be sheared off smoothly.

Hierdurch wird der Bauraum der Strang- oder Rohrpresse auf das notwendige Minimum begrenzt und gleichzeitig die für das Abscheren erforderliche Nebenzeit verkürzt. Gleichzeitig kann durch das vertikale Verschieben der Schervorrichtung vorzugsweise senkrecht zur Strangpressrichtung ein genauer Trennschnitt erfolgen. Insbesondere auf die Bereitstellung von Schwenkantrieben für die Schervorrichtung oder zumindest deren Schermesser kann vorzugsweise verzichtet werden.As a result, the installation space of the extrusion or pipe press is limited to the necessary minimum and at the same time the non-productive time required for shearing is shortened. At the same time, by moving the shearing device vertically, a precise severing cut can be made, preferably perpendicular to the extrusion direction. In particular, the provision of swivel drives for the shearing device or at least its shearing blades can preferably be dispensed with.

Bevorzugt wird, wenn der horizontale Verschiebeweg der Schervorrichtung mehr als 100 mm, vorzugsweise zwischen 150 oder 250 mm, insbesondere bevorzugt etwa 200 mm, beträgt. Hierdurch wird eine Strang- oder Rohrpresse geschaffen, die in der Lage ist, die Abschervorrichtung von dem Werkzeug horizontal wegzufahren und vorzugsweise, ausschließlich in der Vertikalen anzuheben.It is preferred if the horizontal displacement path of the shearing device is more than 100 mm, preferably between 150 or 250 mm, particularly preferably about 200 mm. In this way, an extrusion or pipe press is created which is able to move the cutting device away from the tool horizontally and preferably to lift it exclusively in the vertical direction.

In einer weiteren bevorzugten Ausgestaltungsform der Erfindung ist der Vertikalhub der Schervorrichtung kleiner als 600 mm, vorzugsweise kleiner als 500 mm, insbesondere bevorzugt zwischen 450 und 500 mm, eingestellt. Hierdurch wird gegenüber Strang- oder Rohrpressen mit einem Vertikalhub von üblicherweise mehr als 800 mm eine deutliche Reduzierung des Bauraums erzielt. Die Schervorrichtung sollte dabei vorzugsweise aus dem Verfahrweg des Werkzeugs nach oben entfernt werden können und dann mittels horizontaler Verschiebung in eine Ruheposition oberhalb des Werkzeugs und vorzugsweise anliegend an den Gegenholm verschoben werden. Hierdurch wird eine Schervorrichtung geschaffen, deren Weg von ihrer Ruheposition zu einer Arbeitsposition optimal verkürzt wird und gleichzeitig keine Einschränkung des Pressvorgangs selbst bedingt. Hierdurch werden zuletzt auch die Nebenzeiten auf ein notwendiges Minimum begrenzt.In a further preferred embodiment of the invention, the vertical stroke of the shearing device is set to be less than 600 mm, preferably less than 500 mm, particularly preferably between 450 and 500 mm. This results in a significant reduction in the installation space compared to extrusion or pipe presses with a vertical stroke of usually more than 800 mm achieved. The shearing device should preferably be able to be removed upwards from the travel path of the tool and then be moved by means of horizontal displacement into a rest position above the tool and preferably adjacent to the counter bar. This creates a shearing device whose path from its rest position to a working position is optimally shortened and, at the same time, does not restrict the pressing process itself. As a result, the non-productive times are also limited to a necessary minimum.

Es wird in diesem Zusammenhang insbesondere bevorzugt, wenn ein Hydraulikzylinder zur Bewirkung der Vertikalbewegung der Schervorrichtung und / oder ein elektrischer Antrieb zur Bewirkung der Horizontalbewegung vorgesehen sind. Antriebe sind in der Lage, vorgegebene Verschiebungen in kurzer Zeit und positionsgenau durchzuführen. Darüber hinaus können Hydraulikzylinder in erfindungsgemäßen Strang- oder Rohrpressen die ohnehin vorgesehenen Hydraulikeinrichtungen nutzen und sind in der Lage, die zum Abscheren des Pressrests erforderlichen Kräfte aufzubringen.In this context, it is particularly preferred if a hydraulic cylinder is provided to effect the vertical movement of the shearing device and / or an electric drive is provided to effect the horizontal movement. Drives are able to carry out specified shifts in a short time and with precise positioning. In addition, hydraulic cylinders in extrusion or pipe presses according to the invention can use the hydraulic devices provided anyway and are able to apply the forces required to shear off the press residue.

Gemäß einem weiteren Aspekt der Erfindung wird ein Verfahren zum Abtrennen eines Pressrests beim Strang- und Rohrpressen unter Verwendung einer Strang- oder Rohrpresse gemäß dem ersten Aspekt der Erfindung beansprucht. Das erfindungsgemäße Verfahren umfasst zumindest die Schritte des Pressens eines Werkstücks von einem Blockaufnehmer gegen den Gegenholm, des Zurückfahrens des Blockaufnehmers nach dem Pressen in eine Ausgangsposition, des vertikalen Verschiebens der Schervorrichtung mit der Trennschere zum Abscheren des Pressrests, des vertikalen Zurückfahrens der Schervorrichtung nach dem Abscheren und des horizontalen Verschiebens der Schervorrichtung in eine Ruheposition.According to a further aspect of the invention, a method for separating a press residue during extrusion and tube pressing using an extrusion or tube press according to the first aspect of the invention is claimed. The method according to the invention comprises at least the steps of pressing a workpiece from a block picker against the counter spar, moving the block picker back into an initial position after pressing, vertically moving the shearing device with the cutting shears to shear off the press residue, and vertically retracting the shearing device after shearing off and horizontally displacing the shearing device to a rest position.

Bevorzugt wird in diesem Zusammenhang, wenn die Schervorrichtung und insbesondere ein Schneidmesser oder eine Scherplatte der Schervorrichtung zumindest während des Abscherens parallel zum Gegenholm ausgerichtet ist. Besonders bevorzugt wird, wenn die Schervorrichtung während des gesamten Verfahrens parallel zum Gegenholm ausgerichtet ist. Hierdurch wird ein Verfahren zur Verfügung gestellt, bei dem auf das Verschwenken der Schervorrichtung oder von Teilen der Schervorrichtung vollkommen verzichtet werden kann und gleichzeitig ein exakt senkrechter Trennschnitt beim Abscheren des Pressrests sichergestellt ist. Auch das Zurücksetzen der Schervorrichtung in ihre Ruheposition erfolgt ohne die Notwendigkeit von Verschwenkungen und unter Vermeidung von Reibung zwischen der Schervorrichtung und dem Werkzeug oder Gegenholm.In this context, it is preferred if the shearing device and in particular a cutting knife or a shear plate of the shearing device is aligned parallel to the counter bar at least during shearing. It is particularly preferred if the shearing device is aligned parallel to the counter spar during the entire process. This provides a method in which the pivoting of the shearing device or parts of the shearing device can be completely dispensed with and at the same time an exactly vertical severing cut is ensured when the pressed residue is sheared off. The resetting of the shear device into its rest position also takes place without the need for pivoting and with avoidance of friction between the shear device and the tool or counter bar.

6. Detaillierte Beschreibung der Figuren6. Detailed description of the figures

Figur 1 zeigt eine schematische Ansicht einer erfindungsgemäßen Strang- oder Rohrpresse 1 in einer Ruheposition, wobei eine ein Schermesser 4a tragende Schervorrichtung 4 oberhalb eines Werkzeugs 9 zwischen einem Gegenholm 3 und einem Blockaufnehmer 2 angeordnet ist. Der Blockaufnehmer 2 drückt einen (nicht dargestellten) Block durch das Werkzeug 9 und den Gegenholm 3 hindurch, um das Strangpresserzeugnis herzustellen. In dieser Arbeitsstellung der Strang- oder Rohrpresse 1 verbleibt die Schervorrichtung 4 so nach oben verschoben, dass sie vollständig oberhalb des Werkzeugs 9, jedoch lediglich seitlich versetzt zum Gegenholm 3 in ihrer Ruheposition verbleibt. Die vertikale und horizontale Verschiebbarkeit der Schervorrichtung 4 wird in dieser Ausführungsform durch einen hydraulischen Verschiebezylinder 7 sowie einen Elektroantrieb 6 bewirkt. Figure 1 shows a schematic view of an extrusion or pipe press 1 according to the invention in a rest position, a shearing device 4 carrying a shear knife 4a being arranged above a tool 9 between a counter bar 3 and a billet pick-up 2. The block receiver 2 pushes a block (not shown) through the tool 9 and the counter bar 3 in order to produce the extruded product. In this working position of the extruder or pipe press 1, the shearing device 4 remains shifted upwards in such a way that it remains in its rest position completely above the tool 9, but only laterally offset from the counter bar 3. The vertical and horizontal displaceability of the shearing device 4 is brought about in this embodiment by a hydraulic displacement cylinder 7 and an electric drive 6.

Figur 2 zeigt einen ersten Schritt bei Ausführung des erfindungsgemäßen Verfahrens, bei dem die Schervorrichtung 4 unter Einwirkung des Hydraulikzylinders 6 horizontal in Richtung X nach rechts eine Position verschoben ist, bei der die Schervorrichtung 4, insbesondere das Schermesser 4a, fluchtend zur rechten Kante des Werkzeugs 9 am Gegenholm 3 angeordnet ist, wobei aus der rechten Seite des Werkzeugs 9 der Pressrest 5 hervorsteht. In dieser Phase des erfindungsgemäßen Verfahrens ist der Blockaufnehmer 2 nach rechts entgegen der Strangpressrichtung verschoben worden, um nach Abtrennung des Pressrests 5 einen weiteren Block auf den Gegenholm 3 und die Matrize hindurch strangzupressen. Figure 2 shows a first step in the execution of the method according to the invention, in which the shearing device 4 is displaced horizontally in the direction X to the right under the action of the hydraulic cylinder 6, a position in which the shearing device 4, in particular the shearing knife 4a, is aligned with the right edge of the tool 9 on Counter-beam 3 is arranged, the press residue 5 protruding from the right side of the tool 9. In this phase of the method according to the invention, the block pick-up 2 has been shifted to the right against the extrusion direction in order to extrude another block onto the opposing beam 3 and the die after the pressing residue 5 has been separated.

Figur 3 zeigt einen weiteren Schritt des erfindungsgemäßen Verfahrens, bei dem das Schermesser 4a der Schervorrichtung 4 unter Einwirkung des Hydraulikzylinders 7 nach unten entlang des Pfeils Y so bewegt wurde, dass die Schneidkante des Schneidmessers 4a an der rechten Seite des Werkzeugs 9 entlang exakt parallel zu dem Werkzeug 9 nach unten bewegt wurde, und so den Pressrest 5 abgeschert hat. Figure 3 shows a further step of the method according to the invention, in which the shearing knife 4a of the shearing device 4 was moved under the action of the hydraulic cylinder 7 downwards along the arrow Y so that the cutting edge of the cutting knife 4a along the right side of the tool 9 is exactly parallel was moved down to the tool 9, and so has sheared off the press residue 5.

Figur 4 schließlich zeigt wie Figur 1 wieder die Ruheposition der erfindungsgemäßen Strang- oder Rohrpresse 1, bei der die Schervorrichtung 4 entlang des Pfeils Y vertikal nach oben und entlang des Wegs X horizontal nach links in die Ruheposition anliegend an dem Gegenholm 3 verschoben wurde. Das Schneidmesser 4a steht oberhalb des Werkzeugs 9 und gibt somit den Verfahrweg für den Blockaufnehmer 2 auf das Werkzeug 9 und den Gegenholm 3 hin vollkommen frei. Ein Anheben der Schneidvorrichtung 4 über die gezeigte Stellung hinaus oder ein Verschwenken des Schneidmessers 4a aus der dargestellten Vertikalen heraus ist somit nicht erforderlich. Figure 4 finally shows how Figure 1 Again the rest position of the extrusion or pipe press 1 according to the invention, in which the shearing device 4 has been moved vertically upwards along the arrow Y and horizontally to the left along the path X into the rest position adjacent to the counter beam 3. The cutting knife 4a stands above the tool 9 and thus completely releases the travel path for the block receiver 2 towards the tool 9 and the counter bar 3. It is therefore not necessary to raise the cutting device 4 beyond the position shown or to pivot the cutting knife 4a out of the vertical line shown.
