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 DE 102 27 488 B3 bekannt geworden. Aus der gattungsbildenden EP 1 526 930 B1 ist eine Metallstrangpresse mit einem zur Druckölversorgung des Presskolbens bzw. Plungers am Hauptzylinder befestigten Ausgleichsbehälter bekannt. Das die Schieberplatte tragende Gestänge ist mit einem Vor- und Rückzugzylinder und einem außen an der End- bzw. Rückwand des Ausgleichsbehälters befestigten Hydraulik-Anschlußblock ausgebildet. Die auf dem vom Hauptzylindergehäuse entfernten Stangenende angeordnete Schieberplatte gleitet in dem Ausgleichsbehälter, wobei der von der Schieberplatte endseitig abgeschlossene Füllraum über Verbindungsleitungen an den hinter dem Presskolben liegenden Zylinderraum des Hauptzylindergehäuses angeschlossen ist, in den auch eine Druckölleitung mündet.An extruder of this type, in which the tool, common pressure plate, die holder and die, having counter-spar is connected via tie rods or tension lamellae and pressure supports with the cylinder spar is through the DE 102 27 488 B3 known. From the generic EP 1 526 930 B1 a metal extrusion press is known with a pressure vessel to the plunger or plunger attached to the master cylinder reservoir. The rod carrying the slide plate is formed with a forward and retraction cylinder and a fixed outside of the end or rear wall of the surge tank hydraulic connection block. The arranged on the rod end remote from the master cylinder housing Slide plate slides in the expansion tank, wherein the end of the slide plate closed filling space is connected via connecting lines to the lying behind the plunger cylinder chamber of the master cylinder housing into which also opens a pressure oil line.

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.

Nach der EP 1 526 930 B1 sind der als Vor- und Rückzugszylinder ausgebildeten Stange in den vom Füllraum des Ausgleichsbehälters zu dem Zylinderraum hinter dem Presskolben führenden, im Zylindergehäuseboden ausgebildeten Verbindungsleitungen schaltbare Sperrventile zugeordnet. Hiermit lässt sich erreichen, dass zum Vorschub des Presskolbens in seine Arbeitsposition dieser bei geöffneten Sperrventilen, von denen vier vorhanden sind, ausgeführt als Zwei-Wege-Einbauventile, die auch als Logik- oder Cartridge-Ventile bekannt sind, von dem aus dem Füllraum des Ausgleichsbehälters zugeführten Öl umspült wird. Wenn der Presskolben, der einen gleichen Durchmesser wie der Ausgleichsbehälter besitzt, seine Arbeitsposition erreicht hat und mit dem Pressvorgang beginnt, werden die Verbindungsleitungen über die Sperrventile geschlossen, so dass der Schieber die in dem Ausgleichsbehälter verbleibende Ölmenge nur noch in den Tank drückt, während die anschließende Beaufschlagung mit Drucköl, das folglich nicht nachgesaugt werden muss, so dass der Tank weit entfernt sein kann, nur noch über die Druckölleitung erfolgt. Hierzu sind keine großen Querschnitte der Ölleitungen mehr erforderlich, wie es ohne den Ausgleichsbehälter der Fall wäre. Bei Beendigung des Presshubes und der dann bei entsprechender Umsteuerung der Hydaulikeinheit eingeleiteten Rückwärtsbewegung des Presskolbens in seine Ausgangslage im Zylindergehäuse strömt das Öl dann wieder zurück in den Ausgleichszylinder, d.h. das Öl wird im Betrieb der Rohr- und Strangpresse unter Druck hin und her geschoben.After EP 1 526 930 B1 the trained as a forward and return cylinder rod in the filling chamber of the expansion tank to the cylinder chamber behind the plunger leading, formed in the cylinder housing bottom connecting lines switchable shut-off valves are assigned. Hereby can be achieved that for advancing the plunger into its working position, this open with check valves, of which four are present, designed as two-way cartridge valves, which are also known as logic or cartridge valves, from the filling of the Equalizing tank supplied oil is lapped. When the plunger, which has the same diameter as the expansion tank, has reached its working position and begins the pressing process, the connecting lines are closed via the check valves, so that the slider only pushes the amount of oil remaining in the reservoir into the tank, while the subsequent pressurization with pressurized oil, which therefore does not need to be sucked up, so that the tank can be far away, only via the pressure oil line. For this purpose, no large cross-sections of the oil lines longer required, as would be the case without the surge tank. Upon completion of the pressing stroke and then initiated with appropriate reversal of the hydraulic unit backward movement of the plunger into its initial position in the cylinder housing, the oil then flows back into the balancing cylinder, ie the oil is pushed back and forth under pressure during operation of the tube and extruder.

Bei einer durch die EP 0 822 017 B1 bekannt gewordenen "rahmenlosen" Metallstrangpresse soll die Bewältigung großer Volumenströme dadurch erreicht werden, dass zwei oder mehrere Presskolben mit ihre Zylinder nach beiden Seiten durchsetzenden Kolbenstangen gleichen Durchmessers versehen und die beiderseitigen Kolbenstangen gegenüber den Zylindern abgedichtet sind, so dass beidseitig Zylinder-Teilräume gleicher Wirkfläche bestehen, die durch eine zum Arbeitshub durch ein schaltbares Sperrventil verschließbare Kurzschlussleitung miteinander verbunden sind. Für einen schnellen Rückhub und einen Vorlauf im Eilgang sind bei dieser Presse besondere Kolben-Zylinder-Einheiten vorgesehen. Über die die Zylinder-Teilräume beiderseits des Presskolbens verbindende Kurzschlussleitung ist ein schnellerer Übergang des Öls von einem zum anderen Zylinder-Teilraum bei geringem Strömungswiderstand möglich, wobei die Kurzschlussleitungen und die in diesen angeordneten schaltbaren Sperrventile allerdings eine große Bemessung erfordern.In one by the EP 0 822 017 B1 become known "frameless" metal extruder coping with large volume flows is achieved by two or more plunger provided with their cylinders passing through both sides piston rods of the same diameter and the mutual piston rods are sealed against the cylinders, so that on both sides cylinder subspaces the same effective area exist , which are interconnected by a short-circuit line closable to the working stroke by a switchable shut-off valve. For a quick return stroke and a fast forward flow, this press provides special piston-cylinder units. About the cylinder subspaces on both sides of the plunger connecting short circuit line faster transition of the oil from one to the other cylinder subspace with low flow resistance is possible, the short-circuit lines and arranged in these switchable shut-off valves, however, require a large design.

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.

Von einer Strang- und Rohrpresse bzw. Metallstrangpresse 1 ist in Fig. 1 im wesentlichen der Grundrahmen dargestellt. Dieser besteht aus einem Zylinderholm 2 und einem damit über Zuglamellen 3 verspannten, hier nicht dargestellten, am Ende der Zuglamellen 3 lediglich mit der Bezugsziffer 4 angedeuteten Gegenholm. Zur kraftschlüssigen Verbindung dieser Bauteile tragen weiterhin Druckstützen 5 bei, die die Zuglamellen 3 zwischen dem Zylinderholm 2 und dem Gegenholm 4 umschließen. Die Druckstützen 5 dienen außerdem noch zur Führungsaufnahme einer in dem Grundrahmen beweglichen Stempeltraverse 6 und eines beweglichen Blockaufnehmerhalters 7. Der einen Blockaufnehmer bzw. Rezipient 8 aufweisende Blockaufnehmerhalter 7 wird ebenso wie die Stempeltraverse 6, die das voreilende Ende eines in seinem Zylindergehäuse 9 im Gegenholm 4 mit hydrostatischer Lagerung 10 (vgl. Fig. 2) geführten Presskolbens 11 abstützt, mittels im Ausführungsbeispiel Elektromotoren 12 bzw. 13, insbesondere Servomotoren, in Pressrichtung 14 verfahren. Ein solcher Elektromotor 12 bzw. 13 ist an jeder Längsseite des Blockaufnehmerhalters 7 und der Stempeltraverse 6 vorgesehen. Zur Übertragung bzw. Einleitung der Verfahrbewegung kämmen Ritzel der Elektromotoren 12 bzw. 13 mit Zahnstangen.From a strand and tube press or metal extrusion press 1 is in Fig. 1 essentially the base frame shown. This consists of a cylinder spar 2 and thus a tensioned on tension blades 3, not shown here, at the end of the tension blades 3 only indicated by the reference numeral 4 counter-spar. For frictional connection of these components continue to contribute pressure supports 5, which enclose the tension blades 3 between the cylinder spar 2 and the counter-spar 4. The pressure supports 5 are also still used to guide receiving a movable in the base frame stamping Traverse 6 and a movable Blockaufnehmerhalters 7. The a Blockaufnehmer or recipient 8 having Blockaufnehmerhalter 7 as well as the stamping crosshead 6, which is the leading end of a cylinder housing 9 in the counter-4 with hydrostatic bearing 10 (see. Fig. 2 ) guided plunger 11 is supported, by means of the embodiment of electric motors 12 and 13, in particular servomotors, proceed in the pressing direction 14. Such an electric motor 12 or 13 is provided on each longitudinal side of the Blockaufnehmerhalters 7 and the stamping Traverse 6. To transmit or initiate the movement meshing pinion of the electric motors 12 and 13 with racks.

An das rückwärtige Ende des Zylindergehäuses 9 des Zylinderholms 2 ist ein Ausgleichsbehälter 15 und an dessen End- bzw. Rückwand 16 ist eine Zylindereinheit oder ein Hydraulik-Anschlussblock 17 angeschraubt, letzterer beispielsweise ausgeführt wie aus der EP 1 526 930 B1 bekannt. Optional kann die Strang- und Rohrpresse 1 statt mit Elektromotoren 12, 13 für die Verfahr- und Zustellbewegungen der Stempeltraverse 6 und des Blockaufnehmerhalters 7 mit bekannten, hydraulisch beaufschlagten Seitenzylindern und Aufnehmerverschiebezylindern ausgerüstet sein. Zum Stauchen und Pressen eines in den Blockaufnehmer 8 geladenen Blockes besitzt der Presskolben 11 einen Pressstempel 18.At the rear end of the cylinder housing 9 of the cylinder spar 2 is a surge tank 15 and at the end or rear wall 16 is a cylinder unit or a hydraulic connection block 17 is screwed, the latter, for example, as executed from the EP 1 526 930 B1 known. Optionally, the strand and tube press 1 instead of with electric motors 12, 13 for the traversing and advancing movements of the stamping traverse 6 and the Blockaufnehmerhalters 7 with known, hydraulically actuated side cylinders and Aufnehmerverschiebezylindern be equipped. For pressing and compressing a block loaded in the block receiver 8, the pressing piston 11 has a pressing ram 18.

Wie in Fig. 2 dargestellt, ist integriert im Zylindergehäuse 9 des Haupt- bzw. Presszylinders ein zentrales Füllventil 19 ausgebildet, das aus einem großflächigen Ventildeckel 20 und einem Ringzylinder 21 zur Füllventilbetätigung besteht. Das in Fig. 3 als vergrößerte Einzelheit gezeigte Füllventil 19 ist auf einem am rückwärtigen Ende des Presskolbens 11 befestigten, sich in den Ausgleichsbehälter 15 hinein erstreckenden und dort eine Schieberplatte 22 tragenden Gestänge 23 unter Zwischenschaltung einer kragenartigen Verschiebebuchse 24, auf der auch der Ringzylinder 21 sitzt, angeordnet. Bei Beaufschlagung des in Fig. 3 hinteren, rückwärtigen Endes des Zylinderkolbens 25 des Ringzylinders 21 mit Hydrauliköl wird die Verschiebebuchse 24 und damit der Füllventildeckel 20 aus seiner in durchgezogenen Linien gezeigten, einem Dichtring 26 anliegenden Schließposition in die gestrichelt angedeutete Öffnungsposition verstellt, in der der Füllventildeckel 21 in eine Kontur angepasste Ausnehmung 27 des Presskolbens 11 eintaucht.As in Fig. 2 is shown integrated into the cylinder housing 9 of the main or pressing cylinder, a central filling valve 19 is formed, which consists of a large-scale valve cover 20 and a ring cylinder 21 for Füllventilbetätigung. This in Fig. 3 shown as an enlarged detail filling valve 19 is mounted on a at the rear end of the plunger 11, extending into the surge tank 15 and there a slide plate 22 supporting linkage 23 with the interposition of a collar-like bushing 24, on which also the ring cylinder 21 sits arranged. When loading the in Fig. 3 rear, rear end of the cylinder piston 25 of the annular cylinder 21 with hydraulic oil, the sliding bushing 24 and thus the Füllventildeckel 20 is shown in its solid lines, a sealing ring 26 adjacent closed position in the opening position indicated by dashed lines, adjusted in the filling valve cover 21 in a contour-matched recess 27 of the plunger 11 is immersed.

In der Öffnungsposition des Füllventils 19 steht ein großer, freier Durchströmungs- bzw. Ringflächenquerschnitt zur Verfügung, über den das Hydrauliköl aus dem Ausgleichsbehälter 15 ohne großen Widerstand in den Druckraum des Zylindergehäuses 9 hinter dem Presskolben 11 - und umgekehrt - einströmen kann. Zum Zurückziehen des Füllventildeckels 20 in die Schließposition wird der Ringzylinder 21 umgeschaltet, so dass Hydrauliköl vor den Zylinderkolben 25 gelangt, worauf die Verschiebebuchse 24 mit dem Füllventildeckel 20 entsprechend zurückgezogen wird. Die an eine nicht dargestellte Versorgungsquelle angeschlossenen Druckölleitungen zum Einspeisen von Hydrauliköl vor oder hinter den Zylinderkolben 25 sind in Fig. 3 mit 28, 29 und 30 beziffert, wobei der Druckölleitung 28 ein Endlagendämpfungsmittel 31 zugeordnet ist, wie in Fig. 2 skizziert.In the opening position of the filling valve 19 is a large, free Durchströmungs- or annular area cross-section available, via which the hydraulic oil from the surge tank 15 without much resistance in the pressure chamber of the cylinder housing 9 behind the plunger 11 - and vice versa - can flow. To retract the filling valve cover 20 in the closed position of the annular cylinder 21 is switched so that hydraulic oil passes in front of the cylinder piston 25, whereupon the sliding bushing 24 is withdrawn with the filling valve cover 20 accordingly. The connected to a supply source, not shown Pressure oil lines for feeding hydraulic oil in front of or behind the cylinder piston 25 are in Fig. 3 numbered 28, 29 and 30, wherein the pressure oil pipe 28 is associated with a Endlagendämpfungsmittel 31, as in Fig. 2 outlined.

Bei den Zustellbewegungen, d.h. Verfahren der Stempeltraverse 6 und/oder des Blockaufnehmerhalters 7 in Pressrichtung 14 wird von der sich mit verlagernden Schieberplatte 22 über den dann geöffneten Füllventildeckel 20 bzw. den damit freigegebenen, großen Ringflächenquerschnitt das Hydrauliköl aus dem Ausgleichsbehälter 15 in den Druckraum hinter dem Presskolben 11 ausgeschoben, bis der Presskolben 11 seine Position zum Pressvorgang eingenommen hat. Zum anschließenden Pressen wird das Füllventil 19 geschlossen und die Presskraft durch Einspeisung von Hydrauliköl aus einem Tank 32, wie mit dem nach oben gerichteten Pfeil in Fig. 2 angedeutet, in den Druckraum hinter dem Presskolben 11 aufgebracht. Da das Füllventil 19 geschlossen ist, wird mit dem sich in Pressrichtung 14 verlagernden Presskolben 11 von der über das Gestänge 23 nachgezogenen Schieberplatte 22 eine weitere Menge Hydrauliköl aus dem Ausgleichsbehälter 15 und in den Tank 32 ausgeschoben, wie durch den nach unten gerichteten Pfeil in Fig. 2 angedeutet.In the advancing movements, ie, the method of the stamping traverse 6 and / or the Blockaufnehmerhalters 7 in the pressing direction 14 of the displaced with slide plate 22 via the then opened Füllventildeckel 20 and thus released, large annular area cross section, the hydraulic oil from the surge tank 15 in the pressure chamber behind the pressing piston 11 is pushed out until the plunger 11 has taken its position for pressing. For subsequent pressing, the filling valve 19 is closed and the pressing force by supplying hydraulic oil from a tank 32, as with the upward arrow in Fig. 2 indicated, applied in the pressure chamber behind the plunger 11. Since the filling valve 19 is closed, a further amount of hydraulic oil is expelled from the surge tank 15 and into the tank 32 with the pressing piston 14 displaced in the pressing direction 14 by the rod 23 retracted over the rod 23, as indicated by the downward arrow in FIG Fig. 2 indicated.

Zur Vorbereitung eines neuen Lade- und Pressvorgangs strömt bei der Rückwärtsbewegung des Presskolbens 11 das Hydrauliköl über das durch den Ringzylinder 21 wieder geöffnete Füllventil 19 zurück in den Ausgleichsbehälter 15, d.h. das Hydrauliköl wird im Betrieb der Strang- und Rohrpresse 1 stets ohne großen Widerstand hin und her geschoben. Es versteht sich, dass zur Rückwärtsbewegung des Presskolbens 11 die Antriebe (Elektromotoren oder Verschiebezylinder) der Stempeltraverse 6 und des Blockaufnehmerhalters 7entsprechend aktiviert werden.In preparation for a new loading and pressing operation, during the rearward movement of the plunger 11, the hydraulic oil flows back into the expansion tank 15 via the filling valve 19 which is opened again by the ring cylinder 21, ie the hydraulic oil always operates without great resistance during operation of the extrusion and tube press 1 and pushed. It is understood that for the rearward movement of the plunger 11, the drives (electric motors or displacement cylinder) of the stamping crosshead 6 and the Blockaufnehmerhalters 7 are activated accordingly.
