Description
Die Erfindung betrifft eine Strang- und Rohrpresse bzw. Metallstrangpresse, die einen aus einem Zylinderholm und damit verbundenem Gegenholm bestehenden Pressenrahmen aufweist, in dem ein verfahrbarer, einen Blockaufnehmer tragender Blockaufnehmerhalter und eine verfahrbare Stempeltraverse vorgesehen sind, wobei im Zylinderholm ein Haupt- bzw. Presszylinder angeordnet ist, der in seinem Zylindergehäuse einen an seinem vorderen, von der Stempeltraverse abgestützten Ende mit einem Pressstempel versehenen Presskolben aufnimmt, und bei der dem an eine Tankleitung angeschlossenen Zylindergehäuse ein dem Presskolben Hydrauliköl mittels einer auf einem am rückwärtigen Ende des Presskolbens befestigten Gestänge vorgesehenen Schieberplatte zuführender Ausgleichsbehälter zugeordnet ist, wobei das sich im Ausgleichsbehälter erstreckende Gestänge an eine in Pressrichtung hinter der Schieberplatte angeordnete Hydraulikversorgung angeschlossen ist.The invention relates to a strand and tube press or metal extrusion press, which has a consisting of a cylinder spar and associated counter frame press frame in which a movable, a block receiver carrying block pickup holder and a movable stamping Traverse are provided, wherein in the cylinder spar a main or pressing cylinder is arranged, which receives in its cylinder housing at its front, supported by the stamping Traverse end provided with a ram pressing piston, and in which connected to a tank line cylinder housing a plunger hydraulic oil by means provided on a fixed to the rear end of the plunger rod slide plate is associated with supplying expansion tank, wherein the extending in the expansion tank linkage is connected to a arranged in the pressing direction behind the slide plate hydraulic supply.
Eine Strangpresse dieser Art, bei der der das Werkzeug, üblich Druckplatte, Matrizenhalter und Matrize, aufweisende Gegenholm über Zuganker bzw. Zuglamellen und Druckstützen mit dem Zylinderholm verbunden ist, ist durch die
Um einen hohen Nutzungsgrad der Pressen zu erreichen, müssen die Nebenzeiten minimiert werden, insbesondere sollen die dem Blockaufnehmerhalter, in dem der Blockaufnehmer bzw. Rezipient angeordnet ist, und der Stempeltraverse bzw. Laufholm zugeordneten Verschiebe- und Seitenzylinder einen Leerlauf und Rückzug mit möglichst großen Geschwindigkeiten bewältigen können. Hierbei sind große Volumenströme zwischen den Zylindern und dem Öltank mit hoher Strömungsgeschwindigkeit zu bewegen, wobei turbulente Strömungen und in deren Folge Lufteinschlüsse im Öl und Schaumbildung auftreten können. Diesen nachteiligen Betriebsbedingungen kann nur mit aufwendigen Maßnahmen entgegengetreten werden.In order to achieve a high degree of utilization of the presses, the non-productive times must be minimized, in particular, the idler and the side of the cylinder associated with the Blockaufnehmerhalter, in which the block receiver or recipient is arranged, and the stamping cross member or strut associated idle and retreat with the highest possible speeds can handle. Here, large volume flows between the cylinders and the oil tank to move at high flow velocity, turbulent flows and as a result, air pockets in the oil and foaming can occur. These adverse operating conditions can be counteracted only with expensive measures.

Bei einer durch die
Der Erfindung liegt daher die Aufgabe zugrunde, eine Strang- und Rohrpresse bzw. Metallstrangpresse der eingangs genannten Art ohne die beschriebenen Nachteile zu schaffen, insbesondere sollen sich der Hydraulikaufwand verringern und die Nebenzeiten bei einer gleichzeitig kompakten, einfacheren Bauweise verkürzen lassen.The invention is therefore an object of the invention to provide a strand and tube press or metal extruder of the type mentioned without the disadvantages described, in particular, should reduce the hydraulic effort and shorten the non-productive times with a more compact, simpler design.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass das Gestänge mit einem integriert im Übergang vom Ausgleichsbehälter zum Hauptzylinder vorgesehenen, dem dortigen Innendurchmesser des Zylindergehäuses angepassten, in der Öffnungsfunktion einen großen Ringflächenquerschnitt freigebendes Füllventil ausgebildet ist. Durch das zentral in das Zylindergehäuse des Hauptzylinders eingebaute Füllventil steht eine große Ringfläche zur Verfügung, durch die das Öl ohne großen Widerstand aus dem Ausgleichsbehälter in den Druckraum hinter dem Presskolben und bei Umschaltung der Presskolbenbewegung zurück in den Ausgleichsbehälter fließen kann. Das Verschieben bzw. Vorfahren und Zurückziehen des in dem Hauptzylindergehäuse vorzugsweise mit hydrostatischer Lagerung geführten Presskolbens lässt sich damit sehr schnell durchführen, so dass sich die Nebenzeiten für die Zustellung des Presskolbens und Blockaufnehmerhalters verkürzen lassen. Die nach der Zustellung zum Pressen des geladenen Blockes zu einem Strangpressprodukt noch benötigte Menge an Hydrauliköl kannn bevorzugt aus einem Tank oder einer sonstigen Druckmittelversorgung in den Druckraum des Zylindergehäuses hinter dem Presskolben zugeführt werden. Bei Zwischenschaltung eines Tanks ist nur noch ein deutlich geringeres Pendelvolumen erforderlich.This object is achieved in that the linkage is designed with an integrated in the transition from the expansion tank to the master cylinder, the local inner diameter of the cylinder housing adapted, in the opening function a large annular area cross-section releasing filling valve is formed. By the centrally installed in the cylinder housing of the master cylinder filling valve is a large annular area available through which the oil can flow without much resistance from the expansion tank in the pressure chamber behind the plunger and switching the plunger movement back into the expansion tank. The displacement or ancestor and retraction of the guided in the master cylinder housing preferably with hydrostatic bearing plunger can thus be carried out very quickly, so that can shorten the non-productive times for the delivery of the plunger and Blockaufnehmerhalters. The amount of hydraulic oil still required after the delivery for pressing the charged block to produce an extruded product can preferably be supplied from a tank or other pressure medium supply into the pressure chamber of the cylinder housing behind the plunger. When a tank is interposed, only a significantly lower pendulum volume is required.
Eine bevorzugte Ausführung der Erfindung sieht vor, dass das Füllventil aus einem Füllventildeckel, der auf dem Gestänge über eine kragenartige Verschiebebuchse angeordnet ist, und einem die Verschiebebuchse in Pressrichtung hinter dem Ventildeckel umschließenden Ringzylinder besteht, dessen Zylinderkolben abhängig von der mit Hydrauliköl beaufschlagten Kolbenseite die Verschiebebuchse und damit den Ventildeckel entweder in die Schließposition oder in die Öffnungsposition bringt. Wenn der Zylinderkolben, dessen - in Pressrichtung gesehen - vor und hinter dem Zylinderkolben liegenden Druckräume mit entsprechenden Druckmittelleitungen versehen sind, in Pressrichtung beaufschlagt wird, schiebt der Zylinderkolben über den Kragen den Füllventildeckel aus seiner gegen einen Dichtring abgeschlossenen Position in die Öffnungslage, in der der Füllventildeckel bzw. Ventildeckel in eine Ausnehmung des Presskolbens des Hauptzylinders eingreift bzw. -taucht.A preferred embodiment of the invention provides that the filling valve consists of a filling valve cover, which is arranged on the linkage via a collar-like sliding bushing, and an annular bushing surrounding the bushing in the pressing direction behind the valve cover, the cylinder piston depending on the loaded with hydraulic oil piston side the sliding bush and thus brings the valve cover either in the closed position or in the open position. When the cylinder piston, whose - seen in the pressing direction - are provided in front of and behind the cylinder piston pressure medium lines, in the pressing direction, pushes the cylinder piston over the collar the filling valve cover from its closed against a sealing ring position in the open position in which the Füllventildeckel or valve cover engages in a recess of the plunger of the master cylinder or -taucht.
Ein nach einer Ausgestaltung der Erfindung in der Hydraulikleitung zum Zylinderkolben des Ringzylinders vorgesehenes Endlagendämpfungsmittel begünstigt hierbei das Anfahren der Endlagen des Füllventildeckels.A provided according to an embodiment of the invention in the hydraulic line to the cylinder piston of the annular cylinder Endlagendämpfungsmittel in this case favors the start of the end positions of the filling valve cover.
Nach einem vorteilhaften Vorschlag der Erfindung ist das Füllventil im Zylindergehäuse eines Pressenrahmens integriert, bei dem die Stempeltraverse und der Blockaufnehmerhalter mittels Elektromotoren, vorzugsweise Servomotoren, angetrieben sind. Der sehr große, freie Durchströmungsquerschnitt des Füllventils macht dieses besonders geeignet für eine Betriebsweise der Rohr- und Strangpresse mit im Wechselspiel einerseits geschalteten servomotorischen Antrieben zum Verfahren von Stempeltraverse und Blockaufnehmerhalter und andererseits zum Aufbringen der erforderlichen hohen Stauch- und insbesondere Presskraft beim Verpressen des Blockes zu einem Strangpressprodukt. Zum Pressbetrieb wird damit nur noch eine deutlich reduzierte Hydraulik benötigt. Hierbei liegt es im Rahmen der Möglichkeiten, dass sich durch den Einsatz von Rückspeiseeinheiten aus der Bremsenergie der elektro-hydraulischen Antriebseinheiten eine Energieeinsparung erreichen lässt.According to an advantageous proposal of the invention, the filling valve is integrated in the cylinder housing of a press frame, in which the stamping crosshead and the block pickup holder are driven by means of electric motors, preferably servomotors. The very large, free flow cross-section of the filling valve makes this particularly suitable for operation of the tube and extruder with on the one hand switched servomotor drives for moving stamping post and Blockaufnehmerhalter and on the other hand for applying the required high compression and in particular pressing force during pressing of the block an extrusion product. For pressing operation so that only a significantly reduced hydraulics is needed. It is within the scope of the possibilities that can be achieved by the use of regenerative power units from the braking energy of the electro-hydraulic drive units energy conservation.
