Description

Die Erfindung betrifft eine Drahtziehvorrichtung nach den Merkmalen des Oberbegriffes des Anspruches 1. Eine solche Drahtziehvorrichtung ist aus der GB 794316 bekannt.The invention relates to a wire drawing apparatus according to the features of the preamble of claim 1. Such a wire drawing apparatus is known from GB 794316 known.

Zum Stand der Technik ist zunächst auf die EP 1502669 A1 und die EP 0752287 B1 zu verweisen. Weiter auf die GB 781011 . Bei der hieraus bekannten Drahtziehvorrichtung ist die Ziehscheibentrommel im Bereich des Hutbodens mit einer Vertikalstrukturierung versehen, an die sich nach weiter unten eine Horizontalstrukturierung unmittelbar anschließt.The state of the art is first on the EP 1502669 A1 and the EP 0752287 B1 to refer. Continue to the GB 781011 , In the case of the wire drawing apparatus known therefrom, the drawing disk drum is provided in the area of the hat shelf with vertical structuring, to which a horizontal structuring immediately adjoins later on.

Weiter ist auf die GB 794316 zu verweisen, bei welcher eine Vertikalstrukturierung unmittelbar durchgehend bis zu dem Hutboden ausgeführt ist.Next is on the GB 794316 to refer, in which a vertical structuring is carried out directly through to the hat shelf.

Die Erfindung beschäftigt sich, ausgehend von der letztgenannten Druckschrift, mit der Aufgabe eine vorteilhafte Ausgestaltung des Inneren der Ziehscheibentrommel im Hinblick auf eine Kühlung anzugeben.The invention is concerned, starting from the latter document, with the object of providing an advantageous embodiment of the interior of the drawing wheel drum with a view to cooling.

Diese Aufgabe ist beim Gegenstand des Anspruches 1 gelöst, wobei darauf abgestellt ist, dass die Ziehscheibentrommel im Bereich des Hutbodens anschließend an die Strukturierung einen unstrukturierten Bereich aufweist und dass die Höhe der als Rippen ausgebildeten Strukturierung der Höhe der zylindrischen Außenfläche der Ziehscheibentrommel entspricht, jedoch versetzt nach unten, so dass sich eine Überdeckung zu einem wärmemäßig mit am höchsten beanspruchten Einlaufbereich der Ziehscheibentrommel ergibt.This object is achieved in the subject matter of claim 1, wherein it is based on the fact that the drawing disk drum has an unstructured area in the region of the hat shelf following the patterning and that the height of the structuring formed as ribs corresponds to the height of the cylindrical outer surface of the drawing disk drum, but offset down, so that there is an overlap to a heat moderately with the highest demanded inlet region of the drawing wheel drum.

Durch die höhenmäßige Anpassung an die zylindrische Außenfläche ist die Strukturierung auf das beschränkt, kann die Strukturierung nur über eine beschränkte Höhe, jedoch wirksam, vorgesehen werden. Zudem ergeben sich ziehtechnische Vorteile dadurch, dass im Bereich des Hutbodens ein unstrukturierter Bereich vorgesehen ist.Due to the height adjustment to the cylindrical outer surface structuring is limited to that, the structuring can be provided only over a limited height, but effective. In addition, arise Pulling technical advantages in that in the area of the top hat an unstructured area is provided.

Weiter ist bevorzugt vorgesehen, dass die quer zur Rotationsachse gemessene Höhe einer Strukturierung einem Viertel der Wandstärke bis hin zu dem Maß einer Wandstärke der Ziehscheibentrommel entspricht. Hierdurch ist ersichtlich auch sogleich die Tiefe der Täler zwischen den Strukturierungen bestimmt, wobei wiederum bevorzugt in Umfangsrichtung die Strukturierungen jeweils eine gleiche Höhe aufweisen. Abweichend hiervon können jedoch auch einzelne Strukturierungen unterschiedliche Höhe aufweisen.Furthermore, it is preferably provided that the height of a structuring measured transversely to the axis of rotation corresponds to one quarter of the wall thickness up to the extent of one wall thickness of the drawing disk drum. As a result, the depth of the valleys between the structurings is obviously also determined immediately, again preferably in the circumferential direction, the structurings each having the same height. Deviating from this, however, individual structurings may also have different heights.

Es ist jedoch auch bevorzugt, dass die Strukturierungen rotationssymmetrisch ausgebildet sind. Soweit also in diesem Zusammenhang Strukturierungen unterschiedlicher Höhe vorgesehen sind, wechseln diese sich weiter bevorzugt regelmäßig über den Umfang ab.However, it is also preferred that the structurings are rotationally symmetrical. Insofar as structures of different heights are provided in this context, they furthermore preferably alternate regularly over the circumference.

Im Rahmen der Erfindung ist es möglich, dass eine Strukturierung aus einer Abfolge von in Vertikalrichtung aneinander anschließenden Erhebungen besteht. Besonders bevorzugt ist jedoch in diesem Zusammenhang, dass die Strukturierung aus durchlaufenden, in Umfangsrichtung der inneren Trommelfläche beabstandeten Rippen besteht. Dadurch, dass die Strukturierung sich in Richtung der Rotationsachse nur über einen Teil der Innenwandung erstreckt, wird nur vergleichsweise wenig Flüssigkeit in die Zwischenräume zwischen den Strukturierungen nach vertikal oben, oberhalb der Düse einströmen. Hiermit ist der Tatsache Rechnung getragen, dass im Regelfall die die Kühlflüssigkeit ausbringende, auf die Strukturierung zugerichtete Düse nicht einem Deckenbereich (Hutboden) der Ziehtrommel zugeordnet ist, sondern bevorzugt etwa in mittlerer vertikaler Höhe der Ziehtrommel angeordnet ist. Darüber hinaus ist der Kühlbedarf einer solchen Ziehtrommel auch im unteren, dem Hutrand zugeordneten Bereich, am höchsten, denn dort wird die größte Zieharbeit der Drähte mit entsprechender Erwärmung verrichtet. Die Strukturierung erstreckt sich auch im Bereich des Einlaufrandes (bezogen auf die Außenfläche der Ziehtrommel). Unterhalb dieses Randes, wie auch oberhalb, in einem gewissen Abstand zur Decke der Ziehtrommel, fehlt dann die Strukturierung vollkommen. Insofern ist eine unstrukturierte Innenwandung verwirklicht.In the context of the invention, it is possible that a structuring consists of a sequence of elevations adjoining one another in the vertical direction. However, in this context, it is particularly preferred for the structuring to consist of continuous ribs spaced in the circumferential direction of the inner drum surface. Because the structuring extends in the direction of the axis of rotation over only a part of the inner wall, only comparatively little liquid will flow into the interspaces between the structurings vertically above, above the nozzle. Hereby, the fact is taken into account that as a rule the nozzle which discharges the cooling liquid and is aimed at the structuring is not assigned to a cover area (hat bottom) of the drawing drum but is preferably arranged approximately in the middle vertical height of the drawing drum. In addition, the cooling requirement of such Drawing drum also in the lower, the Hutrand assigned area, highest, because there the largest drawing work of the wires is done with appropriate heating. The structuring also extends in the region of the inlet edge (relative to the outer surface of the drawing drum). Below this edge, as well as above, at a certain distance to the ceiling of the drawing drum, then missing the structuring completely. In this respect, an unstructured inner wall is realized.

Die bereits weiter oben angesprochene Höhe einer Strukturierung bzw. Rippe, gemessen quer zur Rotationsachse, entspricht bevorzugt etwa 1/3 bis 2/3 der Wandstärke (ohne Rippen) der Ziehtrommel in diesem Bereich.The above-mentioned height of a structuring or rib, measured transversely to the axis of rotation, preferably corresponds to about 1/3 to 2/3 of the wall thickness (without ribs) of the drawing drum in this area.

Wie bereits angesprochen ist der Fluidauslass der Kühleinrichtung bevorzugt in radialer Überdeckung zu der Strukturierung. Weiter bevorzugt handelt es sich um eine Sprühdüse, die also die Kühlflüssigkeit, in der Regel Wasser, unmittelbar auf die an der feststehenden Düse vorbei rotierende innere Trommelfläche sprüht.As already mentioned, the fluid outlet of the cooling device is preferably in radial overlap with the structuring. More preferably, it is a spray nozzle, which thus sprays the cooling liquid, usually water, directly onto the inner drum surface rotating past the stationary nozzle.

Nachstehend ist die Erfindung des Weiteren anhand der beigefügten Zeichnung, die jedoch lediglich ein Ausführungsbeispiel darstellt, erläutert. Hierbei zeigt:

Figur 1
den grundsätzlichen schematischen Aufbau einer Ziehscheibentrommel mit zugeordnetem Antrieb;
Figur 2
einen Querschnitt durch den Zylinderteil einer Ziehschei-bentrommel; und
Figur 3
einen Querschnitt des Gegenstandes gemäß Figur 2, geschnitten entlang der Line III-III.
In the following, the invention will be explained further with reference to the attached drawing, which, however, represents only one embodiment. Hereby shows:
FIG. 1
the basic schematic structure of a pulley drum with associated drive;
FIG. 2
a cross section through the cylinder part of a Ziehschei-bentrommel; and
FIG. 3
a cross section of the article according to FIG. 2 , cut along the line III-III.

Dargestellt und beschrieben ist zunächst, mit Bezug zu Figur 1, eine Ziehscheibentrommel 1 einer insgesamt eine Vielzahl von solchen Ziehscheibentrommeln 1 aufweisenden Drahtziehvorrichtung.Shown and described is first, with reference to FIG. 1 a drawing disk drum 1 of a total of a plurality of such drawing disk drums 1 having wire drawing apparatus.

Die Ziehscheibentrommel 1 weist einen bevorzugt schraubverbundenen Deckel 3 auf, der seinerseits von einem Antrieb 4 vermittels einer Welle 5 angetrieben ist.The drawing disk drum 1 has a preferably screw-connected cover 3, which in turn is driven by a drive 4 by means of a shaft 5.

Der Deckel 3 bildet hinsichtlich eines insgesamt hutförmigen Profils der Ziehscheibentrommel 1 den Hutboden.The lid 3 forms the Hutboden with respect to a total hat-shaped profile of the drawing disk drum 1.

Im Inneren der Ziehscheibentrommel 1 ist eine Kühlflüssigkeitsdüse 6 angeordnet, die Kühlflüssigkeit, beim Ausführungsbeispiel Wasser 7, auf eine innere Trommelfläche 8 sprüht.Inside the drawing disk drum 1, a cooling liquid nozzle 6 is arranged, which sprays cooling liquid, in the exemplary embodiment water 7, onto an inner drum surface 8.

Im unteren Bereich der Ziehscheibentrommel 1 ist der Motor 4 an einer feststehenden Halterung 9 angeflanscht, die zugleich Übergangsbereiche 10 zu der rotierenden Trommel 1 ausbildet.In the lower region of the drawing disk drum 1, the motor 4 is flanged to a fixed holder 9, which at the same time forms transitional regions 10 to the rotating drum 1.

Hinsichtlich der Ausgestaltung der Ziehscheibentrommel 1 in weiterer Einzelheit ist auf die Figuren 2 und 3 Bezug genommen. Im Inneren der Ziehscheibentrommel 1 sind vertikal verlaufende Rippen 11 ausgebildet. Die Höhe der Rippen 11, gemessen quer zu einer Rotationsachse R der Ziehscheibentrommel, entspricht etwa der Wandstärke der Ziehscheibentrommel in dem Bereich, in dem die Rippen ausgebildet sind. Bei der Ziehscheibentrommel selbst kann es sich um ein aus einem Stahlblech hergestelltes Teil handeln. Die Rippen 11 können aus einem zunächst vorgesehenen insoweit annähernd zweifache Wandstärke aufweisenden Bereich des Stahlblechs durch vertikales Räumen gebildet sein. Sie können aber auch bei einem Stahlgussteil sogleich angeformt sein. Im Weiteren könnten die Rippen 11 auch durch ein inneres Aufsetzteil, das bspw. angeschweißt ist, gebildet sein. Hierzu würde es sich dann im Einzelfall empfehlen, noch in Umfangsrichtung verlaufende Querhalterungen auszubilden, die dann geeigneterweise im Bereich der Täler zwischen den Rippen 11, eine wesentlich geringere Höhe aufweisen würden als die Rippen 11.With regard to the configuration of the drawing wheel drum 1 in further detail is on the Figures 2 and 3 Referenced. Inside the drawing disk drum 1, vertically extending ribs 11 are formed. The height of the ribs 11, measured transverse to an axis of rotation R of the drawing wheel drum, corresponds approximately to the wall thickness of the drawing wheel drum in the area in FIG the ribs are formed. The drawing wheel drum itself may be a part made of a steel sheet. The ribs 11 may be formed by an initially provided so far approximately twice wall thickness having region of the steel sheet by vertical spaces. But you can also be molded immediately at a steel casting. Furthermore, the ribs 11 could also be formed by an inner attachment part, which, for example, is welded. For this purpose, it would then be recommended in an individual case, still extending in the circumferential direction transverse brackets, which would then suitably have in the region of the valleys between the ribs 11, a much lower height than the ribs 11th

Die Höhe h der Rippen 11 entspricht etwa der Höhe h' der zylindrischen Außenfläche der Ziehscheibentrommel. Jedoch etwas versetzt nach unten, so dass sich eine Überdeckung zu dem wärmemäßig auch mit am höchsten beanspruchten Einlaufbereich E der Ziehscheibentrommel ergibt.The height h of the ribs 11 corresponds approximately to the height h 'of the cylindrical outer surface of the drawing disk drum. However, slightly offset downwards, so that there is an overlap to the thermally even with the most heavily used inlet region E of the drawing wheel drum.

Die auf die Rippen 11 gesprühte Spülflüssigkeit wird über ein nicht dargestelltes System abgesaugt und im Kreislauf geführt, ggf. unter zwischenzeitlicher Kühlung.The rinsing liquid sprayed onto the ribs 11 is sucked off via a system (not shown) and recirculated, if necessary with intermittent cooling.
