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, wobei die Arme der beiden Greifer einteilig gestaltet und derart schwenkbar sind, daß die Greifer in die Auslaufbahn hinein bzw. aus der Auslaufbahn heraus verschwenkbar sind.The invention relates to a take-off device on an extrusion press Run-out path for the support of the elongated, ejected from the extrusion press Workpiece, the face of a movable by the trigger device Gripper is graspable, with two spaced apart, parallel to the discharge path, above the runout and to the side of an imaginary vertical Longitudinal median plane of the runout rails are set and along each rail has a carriage that is mounted on each of the two Carriage is arranged an arm carrying a gripper, the arms of the two Gripper designed in one piece and are pivotable such that the gripper in the Run-out path are pivotable in and out of the run-out path.

Abzugsvorrichtungen bei Strangpressen sind an sich bekannt (EP-A-04 71 339; DE-A-30 40 236).Extraction devices in extrusion presses are known per se (EP-A-04 71 339; DE-A-30 40 236).

Bei einer durch offenkundige Benutzung bekanntgewordenen 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.In a construction that has become known through public use the rails running parallel to the run-out track, on which the wagons are attached the grippers are movably supported, vertically one above the other on the side of the discharge path, the arms that are articulated on the wagon and that carry the grippers are formed in several parts, and the sections forming an arm against each other are rotatable and pivotable or displaceable, so that the grippers that in the case of active use, drive directly above the run-out path, unhindered can go through the intended withdrawal distance.

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. In another known trigger device (DE-PS-39 17 002) are Rails for the wagons with the grippers above the discharge path and on the side an imaginary vertical longitudinal median plane of the same and also here the arms connecting the grippers and carriages are designed in several parts. This multi-part arms and those for their twisting and pivoting or mutual Displacement provided actuators and actuators make extraordinary complex and complicated components that are expensive to manufacture are and which also require considerable maintenance.

Des weiteren ist hier noch die Abzugsvorrichtung nach der JP-Y-59 022 883 zu nennen, bei welcher die Schienen für die Wagen mit den Greifern ebenfalls oberhalb der Auslaufbahn und seitlich einer gedachten vertikalen Längsmittelebene derselben angeordnet sind. Hier sind die Greifer an Armen befestigt, mit welchen sie in die Auslaufbahn hin bzw. aus der Auslaufbahn heraus verschwenkbar sind. Die Schwenkachsen liegen hier parallel zur Auslaufbahn. Diese Anordnung und Lagerung der Greifer bedingt eine erhebliche Baubreite der Abzugsvorrichtung, da bei relativ kleinen Schwenkwinkeln, die unter 90 ° liegen, doch große Verstellwege zurüekgelegt werden müssen, was entsprechend lange Hebelarme voraussetzt, die ihrerseits wiederum die große Baubreite bedingen.Furthermore, the trigger device according to JP-Y-59 022 883 is also closed here name, in which the rails for the car with the grippers also above the run-out path and laterally an imaginary vertical longitudinal median plane the same are arranged. Here the grippers are attached to arms with which they can be pivoted into the run-out path or out of the run-out path. The swivel axes are parallel to the run-out path. This arrangement and Storage of the gripper requires a considerable width of the trigger device, because with relatively small swivel angles that are less than 90 °, large adjustment ranges must be covered, which requires correspondingly long lever arms, which in turn require the large width.

Ausgehend von diesem Stand der Technik zielt die Erfindung darauf ab, eine Abzugsvorrichtung der eingangs erwähnten Art konstruktiv einfach mit möglichst geringer Baubreite zu gestalten, was erfindungsgemäß dadurch gelingt, daß die gegebenenfalls im wesentlichen L-förmig gestalteten Arme um horizontale und 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 Auslaufbahn 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 provide a trigger device of the type mentioned at the beginning in a structurally simple manner, if possible to design a smaller overall width, which is achieved according to the invention in that the possibly substantially L-shaped arms around horizontal and Axes pivotable at right angles to the direction of ejection of the extrusion press are. The two are each expediently forming an L-shaped arm Leg rigidly connected to one another or the arm itself is designed in one piece. Welded structures are expediently provided for this. Are the further the two L-shaped arms are designed identically and are the ones carrying the grippers horizontal leg of these arms to the vertical longitudinal median plane of the Outfeed path directed, so attach the gripper, which is not insignificant Strong, torsion-resistant supports are available to absorb forces. Is provided according to a further feature of the invention that the on the car legs of each arm pivoted about a horizontal axis in its swivel plane is cranked or bent, so for accommodation and favorable structural conditions for the points of attack of the adjustment mechanism created.

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 is on the front side or ejection side of an extrusion press, not shown here, and on which is the elongated workpiece ejected from the extruder, hereinafter Extruded profile called 2, picks up. Laterally this runway 1 is a support frame 3 arranged with an upper horizontal boom 4. Along the runway 1, which can be up to fifty meters or more long (the runway 1 extends at right angles to the plane of the drawing in Fig. 1), there are several such boom 4 provided. Rails 5 and 6 are now on these arms 4 set, both of which lie in an imaginary, common horizontal plane 23 and which in relation to the vertical longitudinal median plane 7 of the outlet track 1 are arranged symmetrically. The two rails 5 and 6 run parallel to Longitudinal extension of the run-out track 1. There is a on each of the two rails 5 and 6 Carriages 8, 9 movably supported. On each of the two carriages, which are identical Have structure is now around a horizontal axis 10 or 11, which is rectangular to the longitudinal center plane 7 of the outlet path 1, a one-piece arm 12, 13 by means of a piston-cylinder unit 14 and 15 in a vertical plane pivoted, these one-piece arms 12, 13 are rigid and convenient in themselves here L-shaped. If the arms 12, 13 are L-shaped, as shown here in the exemplary embodiment, the two legs form this L-shape a rigid unit. Like the carriages 8, 9, these are one-piece arms 12, 13 formed identically. If the arms 12, 13 are L-shaped, they are each horizontal legs, which carry the grippers 16, 17, to the longitudinal center plane 7 directed. These grippers can be designed differently. In the shown Embodiment, these grippers 16, 17 each consist of a U-profile piece With relatively high sidewalls. On one of these sidewalls in the area of their free Axis 18 connecting ends are several, parallel to each other, free movable slats 19 pivotally mounted (at right angles to the plane of the drawing in Fig. 1). Grippers of this type are the subject matter of trigger devices Kind known.

    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, those are the drive of the car and the Control of the components serving the arms is 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.2 makes the operation of the extraction device clear: the rails 5 and 6 and the carriages 8 and 9 lie - in relation to the drawing level - one after the other. The grippers 16 and 17, however, lie in one and the same plane (FIG. 1). In 2, the gripper 16 has an ejected from the extrusion press, not shown Extruded profile 2 gripped at the front and pulls it to the right (arrow 20). The gripper 16 is by means of the arm 12 or the piston-cylinder unit 14 lowered to the runway 1. During this pulling process is now running the second carriage 9 to the left (arrow 21), here the gripper 17 and the arm 13 are raised by means of the piston-cylinder unit 15 (see FIG. 1), see above that the cars 8 and 9 can pass each other unhindered, since yes Grippers 16 and 17 are one above the other. The carriage 9 drives to the extrusion press in 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 from the above statements and can be seen that, thanks to the special arrangement of the rails 5 and 6 which carry the grippers 16 and 17 Arms can be made in one piece and therefore very simply. They are practical in one piece, and for their actuation (lifting and lowering) is only a simple piston-cylinder unit required. Instead of piston-cylinder units 14 and 15 other lifting mechanisms can also be used. Despite this very much simple design of the trigger device is one side of the discharge path 1 freely accessible, via which the extracted and deflected extruded profiles 2 can be removed (arrow 22). In the above and illustrated embodiment, the one-piece arms 12 and 13 are L-shaped designed. This L shape is not mandatory for these arms. The poor could also - seen from above - have a curved course. Rather essential is 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 no more There are subdivisions that can be pivoted or rotated relative to one another.
