Description

Die Erfindung bezieht sich zunächst auf eine Drahtziehvorrichtung mit einer Decke, wobei oberhalb der Decke eine Ziehscheibentrommel mit einer Kühlung angeordnet ist und weiter ein Ziehscheibentrommel-Antriebsmotor sowie Ver- und Entsorgungsleitungen für die Kühlung vorgesehen sind.The invention first relates to a wire drawing apparatus with a Ceiling, where above the ceiling, a drawing disc drum with a cooling is arranged and further a drawing-disk drum drive motor as well Supply and disposal lines are provided for cooling.

Weiter bezieht sich die Erfindung auf eine Ziehscheibentrommel für eine Drahtziehvorrichtung, mit einem getriebefrei und koaxial zu der Ziehscheibentrommel verbundenen Ziehscheibentrommel-Antriebsmotor und einer Kühleinrichtung mit den Zu- und Ablauf betreffenden Versorgungsleitungen.Furthermore, the invention relates to a drawing disk drum for a Wire drawing device with a gearless and coaxial with the drawing wheel drum connected draw-plate drum drive motor and a cooling device with the inlet and outlet related supply lines.

Eine mit derartigen Ziehscheibentrommeln ausgerüstete Drahtziehvorrichtung in Geradeausziehversion ergibt sich aus dem Prospekt Koch "Maschinen für die Drahtindustrie", 2.98. Den Ziehscheibentrommeln ist je ein Getriebe im Unterflurbereich derselben zugeordnet. Das Getriebe steht über Keilriemen als Transmissionsmittel mit je einem seitlich abgelegenen Antriebsmotor in Verbindung. Der sitzt einstellbar gelagert an einer Tragwand der Drahtziehvorrichtung. Das beschränkt den Unterbringungsraum für die erforderlichen Ver- und Entsorgungsleitungen, Absaugrohre für Ziehpulver etc. und deren Zugänglichkeit für Wartungszwecke erheblich ein und nimmt überdies Einfluss auf die Bauhöhe.A wire drawing apparatus equipped with such drawing disk drums in straight pull version results from the brochure cook "machines for the wire industry ", 2.98 The drawing disk drums each have a gearbox in the underfloor area assigned to the same. The gearbox is about V-belt as Transmission means with a laterally remote drive motor in conjunction. The sits adjustable mounted on a supporting wall of the wire drawing device. This limits the accommodation space for the required supply and Disposal lines, extraction pipes for drawing powder etc. and their accessibility for maintenance purposes and also has an influence the height.

Der DE-PS 25 53 215 sind weitere Details der Ziehscheibentrommel, respektive Drahtziehvorrichtung entnehmbar, wie eine Flüssigkeit führende Innenkühlung und Kühlluft führende Außenkühlung. DE-PS 25 53 215 are further details of the drawing disc drum, respectively Wire drawing device removable, such as a liquid-conducting internal cooling and cooling air leading external cooling.

Aus der US 6,116,068 ist es grundsätzlich, wenn auch für das Ziehen von Kupferdrähten bei relativ kleinen Anlagen mit relativ kleinen Ziehkräften, bekannt, einen Ziehscheibentrommel-Antriebsmotor getriebefrei und koaxial mit der Ziehscheibentrommel zu verbinden.From US 6,116,068 it is basically, albeit for the drawing of copper wires in relatively small plants with relatively small pulling forces, known a pulley drum drive motor gearless and coaxial with the To connect the drawing disc drum.

Aufgabe der Erfindung ist es, eine Drahtziehvorrichtung bzw. eine Ziehscheibentrommel, wie eingangs angegeben, hinsichtlich der antriebstechnischen /baulichen Mittel zu verbessern.The object of the invention is to provide a wire drawing apparatus or a drawing disk drum, as stated above, with regard to the drive engineering / structural Means to improve.

Diese Aufgabe ist zunächst und im Wesentlichen hinsichtlich der Drahtziehvorrichtung insgesamt bei einer Drahziehvorrichtung gemäß den Merkmalen des Anspruches 1 gelöst, wobei darauf abgestellt ist, dass der getriebefrei und koaxial mit der Ziehscheibentrommel verbundene Ziehscheibentrommel-Antriebsmotor unterhalb der Decke angeordnet ist, wobei zugleich unterhalb der Decke beidseitig, auf der Bedienungsseite und der Rückseite, Ver- und Entsorgungsleitungen untergebracht sind.This task is initially and essentially with regard to the wire drawing apparatus Whole in a Drahziehvorrichtung according to the features of Claim 1, wherein it is pointed out that the transmission-free and coaxial The drawing disk drum drive motor connected to the drawing wheel drum below the ceiling, being at the same time below the ceiling on both sides, on the operating side and the back, and Disposal lines are housed.

Hinsichtlich der Ziehscheibentrommel ist die genannte Aufgabe zunächst und im Wesentlichen beim Gegenstand des Anspruches 1 gelöst, wobei darauf abgestellt ist, dass die Versorgungsleitungen durch den als elektrischen Synchronmotor ausgebildeten Ziehscheibentrommel-Antriebsmotor hindurchgeführt sind.With regard to the drawing disk drum, the aforementioned object is initially and essentially solved in the subject matter of claim 1, wherein it is turned off is that the supply lines through the as a synchronous electric motor trained pulley drum drive motor passed are.

Wesentlich ist also, dass der unterhalb der Decke, welche die Drahtziehvorrichtung der hier betrachteten Art grundsätzlich horizontal aufteilt, angeordenete Ziehscheibentrommel-Antriebsmotor angeordnet ist, derart, dass beidseitig, auf der Bedienungsseite und der Rückseite der Vorrichtung, Ver- und Entsorgungsleitungen untergebracht sind. Diese Anordnung des getriebefrei und koaxial verbundenen Ziehscheibentrommel-Antriebsmotors erbringt eine wesentlich günstigere Gesamtanordnung der Drahtziehvorrichtung.So it is essential that the below the ceiling, which is the wire drawing device the kind considered here in principle divides horizontally Pulley drum drive motor is arranged such that bilaterally, on the operating side and the back of the device, supply and disposal lines are housed. This arrangement of gearless and Coaxially connected drawing-disk drum drive motor provides a substantial more favorable overall arrangement of the wire drawing device.

Hinsichtlich der Ziehscheibentrommel selbst ist auch von Bedeutung, dass die Versorgungsleitungen sogleich durch den Ziehscheibentrommel-Antriebsmotor hindurchgeführt sind. Dies, wie nachstehend noch im Weiteren dann ausgeführt, unter Umständen sogleich durch den als Hohlwelle ausgebildeten Rotor des Ziehscheibentrommel-Antriebsmotors. Andererseits kann es sich aber auch insofern um eine Vollwelle handeln, die entsprechende Bohrungen bzw. Durchlässe aufweist. Ein Synchronmotor, wie hier angesprochen, ist markterhältlich und in den erforderlichen Leistungsbereichen zuverlässig. Es ergibt sich eine kompaktere Bauweise. Das schafft Raumgewinn nicht nur für die genannten seitlichen Bereiche, sondern für den Unterflurbereich schlechthin. Auch im Hinblick auf eine erforderliche Ziehpulver-Absaugvorrichtung. Die Bautiefe der Drahtziehvorrichtung fällt geringer aus. Maßnahmen, wie das Wiederanschweißen gerissener Drähte, werden dadurch wesentlich erleichtert.With regard to the drawing disk drum itself is also important that the Supply lines immediately through the drawing disk drum drive motor passed through. This, as below then executed, possibly immediately formed by the hollow shaft Rotor of drawing wheel drum drive motor. On the other hand it can But also in this respect are a full wave, the corresponding holes or having passages. A synchronous motor, as mentioned here, is marketable and reliable in the required performance areas. It results in a more compact design. That does not only create space for the aforementioned lateral areas, but for the underfloor area par excellence. Also with regard to a required drawing powder suction device. The depth of the wire drawing device is smaller. Measures like that Wiederanschweißen cracked wires, thereby significantly facilitated.

Die Gegenstände der weiteren Ansprüche, die sich sowohl auf die Ausgestaltung der Drahtziehvorrichtung wie auch der Ziehscheibentrommel als solcher beziehen, sind nachstehend in Bezug zu dem Gegenstand des Anspruches 1 erläutert, können aber auch in ihrer unabhängigen Formulierung von Bedeutung sein. So erweist es sich als günstig, dass die Lagerung der Ziehscheibentrommel durch unmittelbare Verbindung mit dem Rotor des Synchronmotors von diesem übernommen ist. Die Nutzung des Lagers des Additionsteils erweist sich als wirtschaftlich, wobei es im Falle leistungsstärkerer Drahtziehvorrichtungen auch sinnvoll sein kann, dass die Lagerung des Rotors des Synchronmotors im Hinblick auf die gleichzeitige Lagerung der Ziehscheibentrommel verstärkt ausgebildet ist. Zudem ist es von Vorteil, dass die Ziehscheibentrommel vermittels eines an den Synchronmotor angeflanschten Scheibenkopfes angetrieben ist. Es erweist sich als baulich günstig, wenn der Scheibenkopf mittels eines Halslagers an den Rotor des Synchronmotors angeflanscht ist. Darüber hinaus besteht ein vorteilhaftes Merkmal darin, dass der Synchronmotor, jedenfalls teilweise, in radialer Überdeckung zu der Ziehscheibentrommel angeflanscht ist. Eine Lösung von sogar eigenständiger Bedeutung ergibt sich ferner dadurch, dass die Ziehscheibentrommel im Querschnitt topfartig ausgebildet ist mit einem dem Synchronmotor zugewandten Topfboden. So erhält man einen nach oben offenen Aufbau, der aber wahlweise durch einen Revisionsdeckel verschlossen werden kann. Der einen praktischen Schutz entfaltende Revisionsdeckel lässt sich bei Bedarf entfernen, so dass im Topfraum untergebrachte Funktionsteile ohne weiteres rasch zugänglich sind. Bspw. Verschleißteile lassen sich so umgehend austauschen. Der Topfboden kann sodann eine Zusatzfunktion erfüllen, indem er zugleich der Übertragung des Antriebsmoments von dem Synchronmotor auf die Ziehscheibentrommel dient. Er übernimmt so Flanschfunktion. Der Topfboden kann zugleich Träger jedenfalls von Teilen einer Kühlvorrichtung sein. Die weist bevorzugt einen geschlossenen Kühlmittelkreislauf auf. Der Anschluss an eine Versorgungsquelle kann über den Rotor gehen, wenn der Rotor des Synchronmotors als Hohlwelle ausgebildet ist. Entsprechend sind Versorgungsleitungen der Kühlvorrichtung durch den achszentralen Hohlraum der Hohlwelle führbar. Eine besonders raumsparende Lösung wird erzielt, wenn der Synchronmotor sich bis in das Innere der topfartigen Ziehscheibentrommel erstreckt. Ein solcher teilweise in die Ziehscheibentrommel eingezogener Motorkörper kann dabei die Funktion eines zentralen Aussteifkernes für die relativ dünnwandige Ziehscheibentrommel übernehmen.The subject matters of the further claims, which are directed to both the embodiment the wire drawing device as well as the drawing disk drum as such are related to the subject matter of claim 1 below but may also be relevant in their independent formulation be. So it turns out to be favorable that the storage of the drawing disc drum by direct connection to the rotor of the synchronous motor taken from this. Use of the storage of the addition part proves economically, and in the case of more powerful wire drawing devices also makes sense that the bearing of the rotor of the synchronous motor in view of the simultaneous storage of the drawing disc drum is formed reinforced. In addition, it is advantageous that the drawing disc drum by means of a flanged to the synchronous motor disc head is driven. It turns out to be structurally favorable if the disc head flanged by a neck bearing to the rotor of the synchronous motor is. Moreover, an advantageous feature is that the synchronous motor, at least partially, in radial overlap to the drawing wheel drum is flanged. A solution of even independent importance also results from the fact that the drawing disk drum in cross section cup-shaped is formed with a synchronous motor facing Pan. So you get an open-top structure, but optional can be closed by a revision cover. The one practical Protection unfolding revision cover can be removed if necessary, so that accommodated in the pot room functional parts readily accessible quickly are. For example. Wear parts can be exchanged immediately. Of the Pot bottom can then fulfill an additional function by at the same time the Transmission of the drive torque from the synchronous motor to the pulley drum serves. He takes over flange function. The pot bottom can at the same time be carriers of parts of a cooling device. The points prefers a closed coolant circuit. The connection to a Supply source can go through the rotor when the rotor of the synchronous motor is designed as a hollow shaft. Corresponding are supply lines the cooling device through the axial center cavity of the hollow shaft feasible. A particularly space-saving solution is achieved when the synchronous motor extends into the interior of the cup-like drawing-disk drum. Such an engine body partially retracted into the drawing wheel drum can the function of a central Aussteifkernes for the relative Take over thin-walled drawing-disc drum.

Den verbindenden Part stellt ein Basisträger 6. Der weist einen peripheren Flansch 7 auf. Letzterer übergreift den oberseitigen Lochrand des Durchbrechungsbereichs 2 und ist dort fixiert.The connecting part is a base support 6. The has a peripheral Flange 7 on. The latter engages over the upper-side hole edge of the opening area 2 and is fixed there.

Die Befestigungsstelle trägt das Bezugszeichen 8. Es kann sich um einen Schraubenkranz handeln.The attachment point is numbered 8. It may be a Act wrench.

Die oberhalb der Decke 4 stehende Ziehscheibentrommel 1 wird von einem unterhalb der Decke 4 angeordneten Ziehscheibentrommel-Antriebsmotor 9 stufenlos in Rotation versetzt bzw. abgebremst. Die Drehung findet um eine geometrische Achse x-x statt. Die Achse x-x kann vertikal ausgerichtet sein. Bevorzugt liegt eine in Drahtziehrichtung liegende Neigung vor. Zusätzlich kann eine frontal gerichtete Neigung eingeräumt sein. Frontal meint eine Bedienungsseite 10 der Anlage.The standing above the ceiling 4 drawing disk drum 1 is of a below the ceiling 4 arranged drawing disc drum drive motor. 9 infinitely rotated or braked. The rotation takes place around one geometric axis x-x instead. The axis x-x can be vertically aligned. Preferably there is a tendency lying in the direction of wire draw. additionally may be given a frontal tilt. Frontal means a control page 10 of the plant.

Der Ziehscheibentrommel-Antriebsmotor 9 ist als elektrischer Synchronmotor ausgebildet. Er ist getriebefrei und mit der Ziehscheibentrommel 1 verbunden. Das geschieht gemäß Grundversion im Bereich der Decke 4 bzw. des Basisträgers 6. Diese Befestigungsstelle ist mit 11 bezeichnet. Sie verbindet den drehenden Teil des Synchronmotors, den Rotor 12 also, mit der topfförmig ausgebildeten Ziehscheibentrommel 1. Letztere schließt befestigungsseitig mit einem Topfboden 13 ab. An dessen Unterseite erstreckt sich ein ringscheibenförmiger Rotorflansch 14, der eine Öffnung 15 des Basisträgers 6 frei durchsetzt.The drawing-disk drum drive motor 9 is a synchronous electric motor educated. It is gear-free and connected to the drawing-disk drum 1. This happens according to the basic version in the area of the ceiling 4 or the base support 6. This attachment point is designated 11. It connects the rotating one Part of the synchronous motor, the rotor 12 so, with the cup-shaped Pulley drum 1. The latter closes on the mounting side with a Pot bottom 13 from. On the underside extends an annular disk-shaped Rotor flange 14 which passes through an opening 15 of the base support 6 free.

Zwischen dem Topfboden 13 und dem Rotorflansch 14 ist die erwähnte Befestigungsstelle 11 ausgebildet, bspw. realisiert als Schraubenkranz.Between the bottom of the pot 13 and the rotor flange 14 is the aforementioned attachment point 11 formed, for example, realized as a screw ring.

Der Stator 16 des elektrischen Synchronmotors steht in fester Verbindung mit dem Basisträger 6. Die diesbezügliche Befestigungsstelle trägt das Bezugszeichen 17 und besteht wiederum aus einem Schraubkranz.The stator 16 of the electric synchronous motor is in solid communication with the base support 6. The relevant attachment point bears the reference numeral 17 and again consists of a screw ring.

Erkennbar ist die Lagerung der Ziehscheibentrommel 1 durch unmittelbare Verbindung mit dem Rotor 12 des Synchronmotors von diesem übernommen. Die Lagermittel des Synchronmotors sind im Allgemeinen entsprechend leistungsfähig ausgelegt. Reicht die gängige Ausstattung nicht, so ist es sinnvoll, die Lagerung des Rotors 12 des Synchronmotors im Hinblick auf die gleichzeitige Lagerung der Ziehscheibentrommel 1 verstärkt auszubilden. Dabei wirkt sich vorteilhaft aus, dass der Topfboden 13 zugleich, und so auf kürzestem Wege, der Übertragung des Antriebsmoments von dem Synchronmotor auf die Ziehscheibentrommel 1 dient. Das schon ergibt gegenseitige Stabilisierung.Recognizable is the storage of the drawing disk drum 1 by immediate Connection with the rotor 12 of the synchronous motor taken from this. The bearing means of the synchronous motor are generally correspondingly powerful designed. If the usual equipment is not enough, then it makes sense the storage of the rotor 12 of the synchronous motor with regard to the simultaneous Storage of the drawing disk drum 1 reinforced train. It works advantageous that the bottom of the pot 13 at the same time, and so on the shortest Wege, the transmission of the drive torque from the synchronous motor on the Drawing disk drum 1 is used. That already results in mutual stabilization.

Der Topfboden 13 geht peripher in die im Wesentlichen zylindrische Topfwand 18 über. Die setzt an einer peripheren Ringstufe 19 des Topfbodens 13 an. Das diesbezügliche Ende ist verdickt ausgebildet und wird im Übrigen von einem freistehenden Ringkragen 20 des Basisträgers 6 umfasst. Hier befindet sich eine fußnahe Aufwickelstelle 21 für den Draht. Es handelt sich um eine rotationssymmetrische Kegelflanke, anteilig gebildet vom Stirnende des Ringkragens 20 und der besagten, nach radial auswärts gerichteten Verdikkung. Hier baut sich von unten her eine Drahtwendel auf, gehend bis zu einer oben gelegenen Abwickelstelle an der Ziehscheibentrommel 1.The pot bottom 13 is peripherally in the substantially cylindrical pot wall 18 over.

It is a matter of a rotationally symmetrical cone flank, proportionately formed by the front end of the Ring collar 20 and the said, radially outward Verdikkung. Here, a wire spiral builds up from below, going up to one Abwickelstelle located at the top of the drawing disk drum 1.

Der Synchronmotor ist, jedenfalls in teilweiser radialer Überdeckung zu der Ziehscheibentrommel 1, angeflanscht. Der Querschnitt des Synchronmotors geht gemäß Zeichnung gegenüber dem topfförmigen Querschnitt der Ziehscheibentrommel 1 realiter leicht zurück. Selbst das ergibt ausreichend Andockfläche.The synchronous motor is, at least in partial radial coverage of the Drawing wheel drum 1, flanged. The cross section of the synchronous motor goes according to drawing with respect to the cup-shaped cross-section of the drawing wheel drum 1 realiter slightly back. Even that gives sufficient docking area.

Die generelle Verwendung eines elektrischen Synchronmotors, seine kompakte Zuordnung zur Ziehscheibentrommel 1 schaffen im Unterflurbereich sowie beidseitig, also auf der Bedienungsseite 10 wie der Rückseite 22, Freiraum 23 für die verschiedenen Ver- und Entsorgungsleitungen für der Kühlung dienende Vorkehrungen, ebenso für ein Absaugrohr für das anfallende Ziehpulver. Im Übrigen lässt sich die Bauhöhe verringern.The general use of an electric synchronous motor, its compact Assignment to the drawing disc drum 1 create in the underfloor area as well on both sides, ie on the operating side 10 as the back 22, space 23rd for the various supply and disposal lines for the cooling serving Preparations, as well for a suction pipe for the resulting drawing powder. Incidentally, the height can be reduced.

Die Rückseite 22 ist durch eine Wand 24 der Drahtziehvorrichtung 3 begrenzt. The rear side 22 is bounded by a wall 24 of the wire drawing device 3.

Die Ziehscheibentrommel 1 weist eine Flüssigkeit führende Innenkühlung auf, bezeichnet als Kühlvorrichtung 25. Sie besteht aus einem gekammerten Ringspalt 26, der über einen Zulauf 27 und einen Ablauf 28 versorgt wird.The drawing disk drum 1 has a liquid-conducting internal cooling, referred to as cooling device 25. It consists of a chambered annular gap 26, which is supplied via an inlet 27 and a drain 28.

Die den Ringspalt 26 zu dem Topfinneren 29 hin abschottenden Mittel sind gängig und sollen hier nicht weiter erörtert werden, nur, dass die Kühlvorrichtung 25 einen geschlossenen Kühlmittelkreislauf aufweist. Im genannten Vorläufer ist dagegen die Technik praktiziert, dass die Kühlvorrichtung 25 hinsichtlich des Ringspaltes einen querschnittsreduzierten, offenen Spalt belässt zum Abfließen und Auffangen des Kühlmittels in einer Rinne 30. Diese Ausstattung ist in der ersten Variante (Fig. 2) praktiziert und kann auch für die zweite Variante (Fig. 3) vorgesehen sein.The annular gap 26 to the interior of the pot 29 wegschottenden means common and will not be discussed further here, just that the cooling device 25 has a closed coolant circuit. In the aforementioned precursor on the other hand, the technique is practiced that the cooling device 25 in terms of the annular gap leaves a cross-section reduced, open gap for draining and collecting the coolant in a channel 30. This equipment is in the first variant (Fig. 2) practiced and can also for the second variant (Fig. 3) may be provided.

Zurückkommend auf die Grundversion bleibt noch festzuhalten, dass der Topfboden 13 Träger jedenfalls von Teilen der Kühlvorrichtung 25 ist. Die sind bodenseitig als zentral gelegene Drehführungen 31, 32 ausgebildet, im Anschluss stehend zu dem erwähnten wandseitigen Zulauf 27 bzw. Ablauf 28. Letztere sind entsprechend der Anzahl der Ringspalte 26 bzw. Kammern anschlussmäßig vorgesehen und mitdrehend. Die Versorgung geschieht vom Unterflurbereich her. Es sei auf den dortigen Anschluss 33 verwiesen. Von hier gehen Versorgungsleitungen zur Kühlvorrichtung 25 aus, verlaufend durch den achszentralen Hohlraum 34 des als Hohlwelle gestalteten Rotors 12. Der entsprechende Hohlwellenmotor geht deutlich aus Fig. 4 hervor.Coming back to the basic version remains to be noted that the Pot bottom 13 carrier in any case of parts of the cooling device 25 is. The are on the bottom side as centrally located rotary guides 31, 32 formed in the Connection standing to the mentioned wall-side inlet 27 and drain 28th The latter are according to the number of annular gaps 26 and chambers connection moderately provided and co-rotating. The supply happens from Underfloor area ago. Please refer to the connection 33 there. From Here, supply lines go to the cooling device 25, running through the axis-central cavity 34 of the rotor 12 designed as a hollow shaft. The corresponding hollow shaft motor is clearly apparent from Fig. 4.

Das nach oben öffnende Topfinnere 29 der Ziehscheibentrommel 1 bietet einen für Montagezwecke sowie für die Wartung günstigen Zugang. Die Öffnung ist durch einen Revisionsdeckel 35 schließbar. The upwardly opening pot interior 29 of the drawing disk drum 1 offers a For mounting purposes as well as for maintenance cheap access. The opening is closed by a revision cover 35.

Nun zur ersten Variante (Fig. 2): Diese ist hinsichtlich der Motorisierung prinzipiell gleichen Aufbaues. Die Bezugsziffern sind, soweit zum Verständnis erforderlich, sinngemäß übertragen, dies zum Teil ohne textliche Wiederholungen.Now to the first variant (Fig. 2): This is in principle in terms of motorization same structure. The reference numbers are to the understanding necessary, transmitted analogously, in part without textual repetitions.

Ein in der genannten Figur erkennbarer baulicher Unterschied ergibt sich jedoch dadurch, dass die Ziehscheibentrommel 1 vermittels eines an den Synchronmotor angeflanschten Scheibenkopfes 36, also von oben her angetrieben ist. Letzterer steht über ein zentrales Halslager 37 mit dem Rotor 12 des Synchronmotors in Verbindung. Der Rotorflansch 14 des Rotors 12 setzt sich zentral im Topfinneren 29 als Wellenstück 38 in Richtung des Scheibenkopfes 36 fort. In Gegenrichtung lädt ein zentraler Anschlussstutzen 39 aus. Der sitzt konuszentriert sowie verschraubt am Wellenstück 38 fest. Die Verbindung des Scheibenkopfes 36 zur Topfwand 18 der Ziehscheibentrommel 1 hin geht über eine Befestigungsstelle 40. Auch diese kann als Schraubkranz realisiert sein.However, a recognizable in the above figure structural difference arises in that the drawing disk drum 1 by means of a to the synchronous motor flanged disk head 36, so driven from above is. The latter is via a central neck bearing 37 with the rotor 12 of the synchronous motor in connection. The rotor flange 14 of the rotor 12 is located centrally in the interior of the pot 29 as a shaft 38 in the direction of the disk head 36th continued. In the opposite direction, a central connecting piece 39 discharges. He sits cone-centered and bolted to the shaft piece 38 firmly. The connection of the Disk head 36 to the pot wall 18 of the drawing disk drum 1 goes over an attachment point 40. These can also be realized as a screw ring.

Den topfinneren Abschluss des Ringspaltes 26 der Kühlvorrichtung 25 stellt hier eine innere, nach oben gerichtete Ringwand 41 des Basisträgers 6. Letzterer geht auswärts gerichtet in eine die Rinne 30 mit bildende Einstülpung 42 über, an der sich das untere Ende der im Grunde zylindrischen Topfwand 18 der Ziehscheibentrommel 1 drehführt.The pot-internal conclusion of the annular gap 26 of the cooling device 25 provides here an inner, upwardly directed annular wall 41 of the base support 6. The latter goes outward into a groove 30 with forming indentation 42nd over, at which the lower end of the basically cylindrical pot wall 18th the drawing disk drum 1 rotates.

Die zweite Variante gemäß Fig. 3 unterscheidet sich vom vorerläuterten Gegenstand baulich dadurch, dass der Synchronmotor sich bis in das Topfinnere 29 der Ziehscheibentrommel 1 erstreckt. Hier ist etwa die halbe vertikale Höhe des Topfinneren 29 genutzt. Die entsprechende Überlappung zur nach oben verlaufenden Ringwand 41 lässt den querschnittsangepassten Umriss des Synchronmotors als zentralen Stützkern fungieren. The second variant according to FIG. 3 differs from the previously described object structurally in that the synchronous motor extends into the interior of the pot 29 of the drawing disk drum 1 extends. Here is about half the vertical height the pot interior 29 used. The corresponding overlap to the top extending annular wall 41 leaves the cross-section adapted outline of the synchronous motor act as a central support core.

Die Ringwand 41 setzt in der in Fig. 2 dargestellten Weise nach oben hin fort. Eine Einsteckbegrenzung wird erreicht durch eine einwärts gerichtete, horizontale Ringschulter 43, an welcher sich die Befestigungsstelle 17 zum Stator 16 hin befindet. Der Rotoranschluss ist wie zu Fig. 2 geschildert.The annular wall 41 continues upward in the manner shown in FIG. An insertion limit is achieved by an inward, horizontal Ring shoulder 43, at which the attachment point 17 to the stator 16 back located. The rotor connection is described as in FIG. 2.

Die Drahtspannung ist selbstregulierend. Das geht über eine Tastrollenregelung. Entsprechender Abgriff kann an einer als Geber fungierenden Bogenzone des Drahtes, wie sie sich an der kopfnahen Abwickelstelle der Ziehscheibentrommel 1 ergibt, erfolgen und in Steuerimpulse für den Synchronmotor umgesetzt werden. So werden die durch dünner werdenden Draht sich stationsweise erhöhenden Drehzahlen der Trommeln exakt herbeigeführt, d. h. es stellt sich die passende Ziehscheibengeschwindigkeit ein.The wire tension is self-regulating. This is possible via a speed control. Corresponding tap can be on a functioning as an encoder arc zone of the wire, as they are at the near-head unwinding of the pulley drum 1 results, and implemented in control pulses for the synchronous motor become. Thus, the thinning wire becomes station by station raising the rotational speeds of the drums exactly, d. H. it puts the appropriate pulley speed.
