Description

„Trommelziehmaschine" "Drum drawing machine"
Die Erfindung betrifft eine Trommelziehmaschine, insbesondere zum Ziehen von Drähten, Rohren und Profilen mit einem Maschinenrahmen, in dem eine Welle drehbar gelagert ist, mit einer auf der Welle befestigten Trommel und mit einer im Wesentlichen tangentialen Trommel festlegbaren Ziehdüse.The invention relates to a drum drawing machine, in particular for drawing wires, tubes and profiles, with a machine frame in which a shaft is rotatably mounted, with a drum attached to the shaft and with a drawing nozzle which can be fixed essentially tangentially.
Maschinen der eingangs genannten Art sind aus dem Stand der Technik bekannt. Bei den bekannten Maschinen aus dem Stand derMachines of the type mentioned at the outset are known from the prior art. In the known machines from the prior art
Technik, wird die Ziehtrommel der Trommelziehmaschine von einem Elektromotor angetrieben. Die Motorwelle ist dazu über ein Getriebe mit der Welle der Trommel verbunden . Als Elektromotoren werden bevorzugt Drehstrommotoren (Asynchronmaschinen oder Synchronmaschinen) benutzt. Die Getriebe werden für eineTechnology, the drawing drum of the drum drawing machine is driven by an electric motor. For this purpose, the motor shaft is connected to the drum shaft via a gear. Three-phase motors (asynchronous machines or synchronous machines) are preferably used as electric motors. The gears are for one
Untersetzung benötigt, um die Drehebewegung der schnelllaufenden Drehstrommaschine in eine langsame Drehbewegung umzusetzen und um das für das Ziehen notwendige hohe Drehmoment zu erzeugen. Ein Nachteil der Verwendung des Getriebes ist, dass solche Getriebe während des Betriebs der Ziehmaschine Lärm erzeugen und einerReduction is required to convert the rotating movement of the high-speed three-phase machine into a slow rotating movement and to generate the high torque required for pulling. A disadvantage of using the gearbox is that such gearboxes generate noise during operation of the drawing machine and one
Wartung bedürfen. Und zwar hat es in der Vergangenheit auch Überlegungen gegeben, Drehstrommaschinen unmittelbar an der Welle der Trommel anzusetzen, das heißt die Motorwelle und die Welle der Trommel drehfest miteinander zu verbinden; die dazu notwendigen langsamlaufenden, drehmomentstarkenNeed maintenance. In the past, there were also considerations to apply three-phase machines directly to the shaft of the drum, that is, to connect the motor shaft and the shaft of the drum in a rotationally fixed manner; the necessary slow-running, high-torque
Drehstrommotoren sind jedoch so aufwendig und kostspielig, dass die Überlegungen nicht ernsthaft weitergeführt wurden.However, three-phase motors are so complex and expensive that the considerations have not been seriously pursued.
Der Erfindung liegt daher das Problem zugrunde, eine Trommelziehmaschine vorzuschlagen, bei der ohne derThe invention is therefore based on the problem of proposing a drum drawing machine, in which without the
Zwischenschaltung eines Getriebes die Trommel der Ziehtrommelmaschine unmittelbar von einem elektrischen Aggregat angetrieben werden kann.Interposition of a gear the drum of Drawing drum machine can be driven directly by an electrical unit.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass die Welle drehfest mit einer Motorwelle eines Elektromotors verbunden ist, dass der Elektromotor ein nach dem Prinzip des Linearmotors arbeitender Elektromotor ist, dessen Rotor (Anker) auf der Welle befestigt ist, und des Stator (Induktor) mit dem Maschinenrahmen verbunden ist. Mit derartigen Elektromotoren , die nach dem Prinzip eines Linearmotors arbeiten, können bei gleicher Drehzahl wesentlich höhereThis object is achieved in that the shaft is rotatably connected to a motor shaft of an electric motor, that the electric motor is an electric motor operating on the principle of the linear motor, the rotor (armature) of which is attached to the shaft, and the stator (inductor) is connected to the machine frame. With such electric motors, which work on the principle of a linear motor, much higher speeds can be achieved at the same speed
Drehmomente erzeugt werden. Da es bei dem Trommelziehen entscheidend auf das Drehmoment der antreibenden Maschine ankommt, können durch die mögliche höhere Drehzahl bei gleichem Drehmoment im Gegensatz zu einer Drehstrommaschine ein schnelleres Ziehen vorgenommen werden. Waren bisherTorques are generated. Since the torque of the driving machine is crucial when pulling the drum, the possible higher speed with the same torque, in contrast to a three-phase machine, allows faster pulling. So far
Ziehleistungen von 1000 Metern pro Minute möglich, können durch die erfindungsgemäße Trommelziehmaschine Ziehleistungen von bis zu 2000 Metern pro Minute erreicht werden.Drawing performance of 1000 meters per minute possible, drawing performance of up to 2000 meters per minute can be achieved by the drum drawing machine according to the invention.
Die Trommelziehmaschine kann gemäß der Erfindung so ausgestaltet sein, dass der Stator Spulen aufweist, die so angeordnet sind , dass die durch die Spulen erzeugbaren Magnetfelder im Luftspalt zwischen Rotor und Stator im Wesentlichen parallel zu der Motorwelle liegen und ein tangential zur Scheibe magnetisches Wanderfeld aufbauen . Die das magnetische Wanderfeld aufbauende Wicklung ist vorteilhaft in einem genuteten Blechpaket untergebracht. Es ist möglich dabei eine Einfachstator- oder Doppelstator-Ausführung zu wählen. Im ersteren Fall befindet sich nur ein bewickelter Stator axial neben der Scheibe. Ihm steht ein unbewickelter magnetischer Rückschluss auf der anderen Statorseite gegenüber. Wird statt des unbewickeltenAccording to the invention, the drum drawing machine can be configured such that the stator has coils which are arranged in such a way that the magnetic fields which can be generated by the coils in the air gap between the rotor and stator are essentially parallel to the motor shaft and build up a traveling magnetic field tangential to the disk. The winding that builds up the magnetic traveling field is advantageously accommodated in a grooved laminated core. It is possible to choose a single stator or double stator version. In the former case, there is only one wound stator axially next to the disk. It is opposed by an unwrapped magnetic yoke on the other side of the stator. Will instead of the unwrapped
Rückschlusses ebenfalls ein bewickelter Stator verwendet, so liegt eine Doppelstator-Anordnung vor. Diese hat den Vorteil ein stärkeres Magnetfeld und damit eine größere tangential wirkende Schubkraft zu erzeugen. Eine besonders leistungsfähige Trommelziehmaschine kann dadurch erreicht werden, dass die Spulen des Stators aus supraleitenden Drähten bestehen .In conclusion also uses a wound stator, there is a double stator arrangement. This has the advantage of a stronger one Magnetic field and thus generate a greater tangential thrust. A particularly powerful drum drawing machine can be achieved in that the coils of the stator consist of superconducting wires.
Der nach dem Prinzip des Linearmotors arbeitende Elektromotor kann synchron oder asynchron betrieben werden. Für einen synchronen Betrieb des Motors kann der Rotor zumindest eine Erregerwicklung tragen. Anstelle der Erregerwicklung kann der Rotor auch mit Permanentmagneten, die ein axiales Magnetfeld erzeugen , aufgebaut sein . In diesem Fall ist zu beachten, dass außer der gewünschten tangentialen, das Drehmoment bildende Kraft noch eine weitere Kraft auftritt, die senkrecht zur Bewegungsrichtung wirkt und die sowohl an den bewickelten Statoren bzw. dem unbewickelten magnetischen Rückschluss und an den Rotor angreift. Das tritt so sowohl am Rotor mit Erregerwicklung als auch an dem Rotor, der mit Permanentmagneten bestückt ist, auf. Bei völliger Symmetrie der Anordnung bewickelte Statoren-Luftspalte und Rotorscheibe heben sich diese Kräfte auf. Mit Rücksicht auf Fertigungstoleranzen sind unter Umständen konstruktive Maßnahmen zum Abfangen nicht kompensierter Kräfte erforderlich . Für den asynchronen Betrieb, kann der Rotor gemäß der Erfindung aus einer Scheibe bestehen. Zur Vergrößerung der tangentialen Kraft und damit des Drehmomentes, können mehrere Linearmotoren, die um einen bestimmten Winkel versetzt sind , angeordnet werden. Es entsteht so ein aufrüstbaresThe electric motor, which works on the principle of the linear motor, can be operated synchronously or asynchronously. The rotor can carry at least one excitation winding for synchronous operation of the motor. Instead of the excitation winding, the rotor can also be constructed with permanent magnets that generate an axial magnetic field. In this case, it should be noted that in addition to the desired tangential force that forms the torque, there is another force that acts perpendicular to the direction of movement and that acts on both the wound stators or the unwound magnetic yoke and on the rotor. This occurs both on the rotor with excitation winding and on the rotor which is equipped with permanent magnets. If the arrangement of the stator air gaps and the rotor disk are completely symmetrical, these forces cancel each other out. With regard to manufacturing tolerances, constructive measures to intercept uncompensated forces may be required. For asynchronous operation, the rotor according to the invention can consist of a disc. To increase the tangential force and thus the torque, several linear motors that are offset by a certain angle can be arranged. This creates an upgradeable one
„Antriebsmodul". Um das Drehmoment erhöhen zu können, ist es möglich mehrere „Antriebsmodule" axial zueinander versetzt anzuordnen. Vorteilhaft sind die Scheiben des Rotors aus einer Aluminiumlegierung, einer Kupferlegierung oder aus Aluminium, Kupfer hergestellt. Die Welle auf der die Trommel befestigt ist und die Motorwelle können entweder einstückig ausgeführt oder über Flansche miteinander verbunden sein."Drive module". To be able to increase the torque, it is possible to arrange several "drive modules" axially offset from one another. The discs of the rotor are advantageously made of an aluminum alloy, a copper alloy or of aluminum, copper. The shaft on which the drum is attached and the motor shaft can either be made in one piece or connected to one another via flanges.

All bearings can be selected as the bearing 3 which meet the loads in the operation of a drum drawing machine.
An dem oberen Ende der Welle 4 sind beabstandet zueinander mehrere Scheiben als Rotor 5 befestigt. Bewickelte Statoren bzw. ein magnetischer Rückschluss befinden sich beidseitig an der Scheibe. Das magnetische Wanderfeld tritt aus den bewickelten Statoren über den oberen Luftspalt, durch die Scheibe über den unteren Luftspalt in den gegenüberliegenden bewickelten Stator oder den magnetischen Rückschluss ein. Es bewegt sich tangential zur Scheibe, erzeugt in gleicher Richtung eine Kraft, die am mittleren Radius der bewickelten Statoren das gewünschte Drehmoment erzeugt.At the upper end of the shaft 4, a plurality of disks are attached as a rotor 5 at a distance from one another. Wrapped stators or a magnetic yoke are located on both sides of the disc. The traveling magnetic field emerges from the wound stators via the upper air gap, through the disk via the lower air gap into the opposite wound stator or the magnetic yoke. It moves tangentially to the disc, generates a force in the same direction that generates the desired torque at the central radius of the wound stators.

Auf dieser Trommel 2 wird im Betrieb das gezogene Material insbesondere Drähte aufgewickelt.At the lower end of the shaft 4, a drum 2 of the drum drawing machine is attached. The drawn material, in particular wires, is wound on this drum 2 during operation.

Vorteil, dass zum einen durch den Wegfall des Getriebes eine spezielle Getriebewartung entfällt, ferner die Lärmemissionen reduziert sind und auch ein höherer Wirkungsgrad erzielt werden kann, da Reibungsverluste, wie sie dem Getriebe zwangsläufig auftreten entfallen. Außerdem können größere Ziehleistungen erzielt werden. The advantage that, on the one hand, there is no need for special gearbox maintenance due to the omission of the gearbox, and also noise emissions are reduced and a higher degree of efficiency can also be achieved, since there is no frictional loss that the transmission inevitably occurs. In addition, larger drawing performances can be achieved.
