Abstract

The puller apparatus is intended for extrusion presses with a delivery track (1) to provide support for the elongate workpiece (2) ejected from the extrusion press. The workpiece (2) can be gripped at the end by a gripper (16, 17) which can be moved by the puller apparatus. Two rails (5, 6) spaced apart from one another and situated laterally with respect to an imaginary vertical longitudinal centre plane (7) of the delivery track (1) are fixed parallel to and above the delivery track (1). A respective carriage (8, 9) can be moved along each rail (5, 6). An arm (12, 13) carrying a gripper (16, 17) is arranged on each of the two carriages (8, 9). The arms (12, 13) are of one-piece configuration and can be pivoted about horizontal axes (10, 11) lying at right angles to the direction of ejection of the extrusion press. The horizontal limbs of these arms (12, 13) of identical design, said limbs carrying the grippers (16, 17), point towards the vertical longitudinal centre plane (7) of the delivery track (1). <IMAGE>

Description

Die Erfindung bezieht sich auf eine Abzugsvorrichtung an Strangpressen mit einer Auslaufbahn für die Auflage des von der Strangpresse ausgestoßenen, langgestreckten Werkstückes, das stirnseitig von einem von der Abzugsvorrichtung bewegbaren Greifer faßbar ist, wobei parallel zur Auslaufbahn zwei voneinander distanzierte, oberhalb der Auslaufbahn und seitlich einer gedachten vertikalen Längsmittelebene der Auslaufbahn liegende Schienen festgelegt sind und entlang einer jeden Schiene je ein Wagen verfahrbar gelagert ist und an jedem der beiden Wagen ein einen Greifer tragender Arm angeordnet ist.The invention relates to a take-off device on extrusion presses with a run-out path for supporting the elongated workpiece which is ejected by the extrusion press and which can be gripped at the end face by a gripper which can be moved by the take-off device, two spaced apart from one another parallel to the run-out path, above the run-out path and laterally one imaginary vertical longitudinal median plane of the runout are fixed rails and a carriage is movably mounted along each rail and an arm carrying a gripper is arranged on each of the two carriages.

Abzugsvorrichtungen bei Strangpressen sind bekannt. Bei einer bekannten Konstruktion liegen die zur Auslaufbahn parallel verlaufenden Schienen, an welchen die Wagen mit den Greifern verfahrbar gelagert sind, seitlich der Auslaufbahn vertikal übereinander, wobei die Arme, die an den Wagen angelenkt sind und die die Greifer tragen, mehrteilig ausgebildet sind, und die je einen Arm bildenden Abschnitte gegeneinander verdreh- und schwenkbar bzw. verschiebbar sind, damit die Greifer, die beim jeweiligen aktiven Einsatz unmittelbar oberhalb der Auslaufbahn fahren, ungehindert die vorgesehene Abzugstrecke durchlaufen können. Bei einer anderen bekannten Abzugsvorrichtung (DE-PS-39 17 002) sind die Schienen für die Wagen mit den Greifern oberhalb der Auslaufbahn und seitlich einer gedachten vertikalen Längsmittelebene derselben angeordnet und auch hier sind die die Greifer und Wagen verbindenden Arme mehrteilig ausgestaltet. Diese mehrteiligen Arme und die für ihre Verdrehung und Verschwenkung bzw. gegenseitige Verschiebung vorgesehenen Stell- und Betätigungsglieder stellen außerordentlich aufwendige und komplizierte Baukomponenten dar, die teuer in der Herstellung sind und die auch einer erheblichen Wartung bedürfen.Extraction devices in extrusion presses are known. In a known construction, the rails running parallel to the run-out track, on which the carriages with the grippers are movably mounted, lie vertically one above the other to the side of the run-out track, the arms which are articulated to the carriage and which carry the grippers being of multiple parts, and the sections forming an arm are rotatable and pivotable or displaceable relative to one another, so that the grippers, which drive directly above the outlet path during the respective active use, can pass through the intended withdrawal path unhindered. In another known trigger device (DE-PS-39 17 002), the rails for the carriage with the grippers are arranged above the discharge path and to the side of an imaginary vertical longitudinal central plane thereof, and here too the arms connecting the grippers and carriages are designed in several parts. These multi-part arms and the actuators and actuators provided for their rotation and pivoting or mutual displacement represent extremely complex and complex components which are expensive to manufacture and which also require considerable maintenance.

Ausgehend von diesem Stand der Technik zielt die Erfindung darauf ab, eine Abzugsvorrichtung der eingangs erwähnten Art konstruktiv einfach zu gestalten, was erfindungsgemäß dadurch gelingt, daß die Arme der beiden Greifer einteilig, gegebenenfalls im wesentlichen L-förmig gestaltet, und um horizontale, rechtwinkelig zur Ausstoßrichtung der Strangpresse stehende Achsen schwenkbar sind. Dabei sind zweckmäßigerweise die beiden je einen L-förmigen Arm bildenden Schenkel starr miteinander verbunden bzw. der Arm selbst ist einstückig ausgestaltet. Zweckmäßig werden dafür Schweißkonstruktionen vorgesehen. Sind des weiteren die beiden L-förmigen Arme gleich gestaltet und sind die die Greifer tragenden waagrechten Schenkel dieser Arme zur vertikalen Längsmittelebene der Auslauf bahn gerichtet, so stehen zur Befestigung der Greifer, die nicht unerhebliche Kräfte aufzunehmen haben, stabile, verwindungssteife Supporte zur Verfügung. Ist nach einem weiteren Merkmal der Erfindung vorgesehen, daß der am Wagen um eine horizontale Achse schwenkbar gelagerte Schenkel eines jeden Armes in seiner Schwenkebene gekröpft bzw. gebogen ist, so werden für die Unterbringung und für die Angriffspunkte der Verstellmechanik günstige konstruktive Voraussetzungen geschaffen.Based on this prior art, the invention aims to make a trigger device of the type mentioned structurally simple, which is achieved according to the invention in that the arms of the two grippers are made in one piece, possibly substantially L-shaped, and around horizontal, at right angles to Ejection direction of the extruder standing axes are pivotable. The two legs, each forming an L-shaped arm, are expediently rigidly connected to one another or the arm itself is designed in one piece. Welded structures are expediently provided for this. Furthermore, the two L-shaped arms are designed identically and the horizontal legs of these arms carrying the grippers are directed toward the vertical longitudinal center plane of the outlet path, so that the grippers are fastened, which is not inconsiderable Strong, torsion-resistant supports are available to absorb forces. If it is provided according to a further feature of the invention that the leg of each arm pivotably mounted on the carriage about a horizontal axis is cranked or bent in its pivoting plane, favorable structural conditions are created for the accommodation and for the points of attack of the adjustment mechanism.

Um die Erfindung zu veranschaulichen, wird ein Ausführungsbeispiel anhand der Zeichnung näher erläutert, ohne sie dadurch auf das gezeigte Ausführungsbeispiel einzuschränken. Es zeigen:

  • Fig. 1 einen Querschnitt durch eine Auslaufbahn einer Strangpresse und Fig. 2 eine Seitensicht.
In order to illustrate the invention, an embodiment is explained in more detail with reference to the drawing, without thereby restricting it to the embodiment shown. Show it:
  • Fig. 1 shows a cross section through an outlet path of an extruder and Fig. 2 is a side view.

Fig. 1 stellt einen Querschnitt durch eine Auslaufbahn 1 dar, die an der Stirnseite bzw. Ausstoßseite einer hier nicht dargestellten Strangpresse anschließt, und auf welcher das von der Strangpresse ausgestoßene langgestreckte Werkstück, nachstehend Strangpreßprofil 2 genannt, aufnimmt. Seitlich dieser Auslaufbahn 1 ist ein Traggestell 3 angeordnet mit einem oberen horizontalen Ausleger 4. Entlang der Auslaufbahn 1, die bis zu fünfzig Meter oder mehr lang sein kann (die Auslaufbahn 1 erstreckt sich rechtwinkelig zur Zeichenebene in Fig. 1), sind mehrere solcher Ausleger 4 vorgesehen. An diesen Auslegern 4 sind nun Schienen 5 und 6 festgelegt, die beide in einer gedachten, gemeinsamen horizontalen Ebene 23 liegen und welche bezogen auf die vertikale Längsmittelebene 7 der Auslaufbahn 1 symmetrisch angeordnet sind. Die beiden Schienen 5 und 6 verlaufen parallel zur Längserstreckung der Auslaufbahn 1. An jeder der beiden Schienen 5 und 6 ist ein Wagen 8, 9 verfahrbar gelagert. An jedem der beiden Wagen, die einen identischen Aufbau besitzen, ist nun um eine horizontale Achse 10 bzw. 11, die rechtwinkelig zur Längsmittelebene 7 der Auslaufbahn 1 steht, ein einteiliger Arm 12, 13 mittels einer Kolben-Zylinder-Einheit 14 und 15 in einer Vertikalebene schwenkbar gelagert, diese einteiligen Arme 12, 13 sind in sich starr und zweckmäßigerweise hier L-förmig ausgebildet. Sind die Arme 12, 13 L-förmig gestaltet, wie hier im Ausführungsbeispiel gezeigt, so bilden die beiden Schenkel dieser L-Form eine starre Einheit. Wie die Wagen 8, 9 sind auch diese einteiligen Arme 12, 13 identisch ausgebildet. Sind die Arme 12, 13 L-förmig gestaltet, so sind ihre jeweils waagrechten Schenkel, die die Greifer 16, 17 tragen, zur Längsmittelebene 7 gerichtet. Diese Greifer können unterschiedlich ausgebildet sein. Im gezeigten Ausführungsbeispiel bestehen diese Greifer 16, 17 aus je einem U-Profilstück mit relativ hohen Seitenwangen. An einer diese Seitenwangen im Bereich ihrer freien Enden verbindenden Achse 18 sind mehrere, parallel zueinander liegende, frei bewegliche Lamellen 19 schwenkbar gelagert (in Fig. 1 rechtwinkelig zur Zeichenebene). Greifer dieser Art sind bei Abzugsvorrichtungen der gegenständlichen Art bekannt.Fig. 1 shows a cross section through an outlet path 1, which connects to the end face or ejection side of an extrusion press, not shown here, and on which the elongated workpiece ejected by the extrusion press, hereinafter referred to as extrusion profile 2, receives. A support frame 3 is arranged to the side of this run-out track 1 with an upper horizontal boom 4. Along the run-out track 1, which can be up to fifty meters or more long (the run-out track 1 extends at right angles to the plane of the drawing in FIG. 1), there are several such booms 4 provided. Rails 5 and 6 are now fixed to these arms 4, both of which lie in an imaginary, common horizontal plane 23 and which are arranged symmetrically with respect to the vertical longitudinal center plane 7 of the run-out path 1. The two rails 5 and 6 run parallel to the longitudinal extent of the run-out path 1. On each of the two rails 5 and 6, a carriage 8, 9 is movably supported. On each of the two carriages, which have an identical structure, there is now a one-piece arm 12, 13 by means of a piston-cylinder unit 14 and 15 in about a horizontal axis 10 or 11, which is perpendicular to the longitudinal center plane 7 of the outlet path 1 pivotally mounted on a vertical plane, these one-piece arms 12, 13 are rigid in themselves and expediently L-shaped here. If the arms 12, 13 are L-shaped, as shown here in the exemplary embodiment, the two legs of this L-shape form a rigid unit. Like the carriages 8, 9, these one-piece arms 12, 13 are of identical design. If the arms 12, 13 are L-shaped, their respective horizontal legs, which support the grippers 16, 17, are directed towards the longitudinal center plane 7. These grippers can be designed differently. In the embodiment shown, these grippers 16, 17 each consist of a U-shaped piece with relatively high side cheeks. On an axis 18 connecting these side walls in the region of their free ends, a plurality of axes lying parallel to one another are free movable slats 19 pivotally mounted (at right angles to the plane of the drawing in Fig. 1). Grippers of this type are known in trigger devices of the type in question.

Aus Zwecken der Übersichtlichkeit sind die dem Antrieb der Wagen und der Steuerung der Arme dienenden Baukomponenten hier nicht dargestellt.For the sake of clarity, the components used to drive the wagons and control the arms are not shown here.

Fig. 2 macht die Arbeitsweise der Abzugseinrichtung deutlich: Die Schienen 5 und 6 sowie die Wagen 8 und 9 liegen - bezogen auf die Zeichenebene - hintereinander. Die Greifer 16 und 17 jedoch liegen in ein und derselben Ebene (Fig. 1). In Fig. 2 hat der Greifer 16 ein von der nicht dargestellten Strangpresse ausgestoßenes Strangpreßprofil 2 stirnseitig gefaßt und zieht dieses nun nach rechts (Pfeil 20). Dabei ist der Greifer 16 mittels des Armes 12 bzw. der Kolben-Zylinder-Einheit 14 zur Auslaufbahn 1 abgesenkt. Während dieses Abziehvorganges fährt nun der zweite Wagen 9 nach links (Pfeil 21), wobei hier der Greifer 17 und der Arm 13 mittels der Kolben-Zylinder-Einheit 15 angehoben sind (vergleiche Fig. 1), so daß die Wagen 8 und 9 ungehindert aneinander vorbeifahren können, da ja die Greifer 16 und 17 sozusagen übereinander liegen. Der Wagen 9 fährt zur Strangpresse in Warteposition.Fig. 2 makes the operation of the trigger device clear: the rails 5 and 6 and the carriage 8 and 9 are - in relation to the drawing plane - one behind the other. The grippers 16 and 17, however, lie in one and the same plane (FIG. 1). In Fig. 2, the gripper 16 has an extruded profile 2 ejected from the extruder, not shown, and pulls it to the right (arrow 20). The gripper 16 is lowered by means of the arm 12 or the piston-cylinder unit 14 to the outlet path 1. During this pulling-off operation, the second carriage 9 now moves to the left (arrow 21), the gripper 17 and the arm 13 being raised here by means of the piston-cylinder unit 15 (see FIG. 1), so that the carriages 8 and 9 are unimpeded can drive past each other, since the grippers 16 and 17 are, so to speak, one above the other. The carriage 9 travels to the extrusion press in the waiting position.

Es ist aus den vorstehenden Darlegungen erkennbar und ersichtlich, daß dank der besonderen Anordnung der Schienen 5 und 6 die die Greifer 16 und 17 tragenden Arme einteilig und damit sehr einfach ausgebildet sein können. Sie sind praktisch einstückig, und zu ihrer Betätigung (Heben und Senken) ist nur eine einfache Kolben-Zylinder-Einheit erforderlich. Anstelle von Kolben-Zylinder-Einheiten 14 und 15 können auch andere Hubmechanismen eingesetzt werden. Trotz dieser sehr einfachen Ausgestaltung der Abzugsvorrichtung ist die eine Seite der Auslaufbahn 1 frei zugänglich, über die die abgezogenen und abgelenkten Strangpreßprofile 2 abtransportiert werden können (Pfeil 22). Im vorstehend gezeigten und erläuterten Ausführungsbeispiel sind die einteiligen Arme 12 und 13 L-förmig gestaltet. Diese L-Form ist für diese Arme nicht zwingend. Die Arme könnten auch - von oben gesehen - einen gebogenen Verlauf aufweisen. Vielmehr wesentlich ist gemäß der Erfindung, daß diese Arme einteilig sind und zwischen den jeweiligen Greifern und den Schwenkachsen 10 und 11 dieser Arme keine weiteren Unterteilungen vorliegen, die gegeneinander schwenkbar oder verdrehbar sind.It can be seen and seen from the above explanations that, thanks to the special arrangement of the rails 5 and 6, the arms carrying the grippers 16 and 17 can be made in one piece and thus very simply. They are practically in one piece and only a simple piston-cylinder unit is required to operate them (lifting and lowering). Instead of piston-cylinder units 14 and 15, other lifting mechanisms can also be used. Despite this very simple design of the take-off device, one side of the run-out path 1 is freely accessible, via which the extruded and extruded profiles 2 can be removed (arrow 22). In the exemplary embodiment shown and explained above, the one-piece arms 12 and 13 are L-shaped. This L shape is not mandatory for these arms. The arms could also have a curved profile when viewed from above. Rather, it is essential according to the invention that these arms are in one piece and between the respective grippers and the pivot axes 10 and 11 of these arms there are no further subdivisions which can be pivoted or rotated relative to one another.
