Die Erfindung betrifft eine Anordnung zum Kühlen wärmebehandelter Drähte mit den im Oberbegriff des Anspruchs 1 angegebenen Merkmalen.The invention relates to an arrangement for cooling heat-treated Wires with the specified in the preamble of claim 1 Features.
Aus der DE 100 58 369 C1 ist eine derartige Anordnung bekannt. Sie enthält eine von einem Drahtführungskanal durchsetzte Kühldüse, welcher durch einen seitlichen Zuflusskanal ein Kühlmittel zugeführt wird, das in der Düse einen sich verjüngenden Kühlmittelkanal durchläuft und aus der Düse als schräg gegen den Draht entgegen dessen Laufrichtung gerichteter Strom austritt und durch einen seitlichen Abflusskanal abgeführt wird.From DE 100 58 369 C1 such an arrangement is known. It contains a penetrated by a wire guide channel Cooling nozzle, which through a lateral inflow channel a coolant is supplied to the nozzle in a passes through the tapered coolant channel and out of the nozzle as obliquely directed against the wire counter to its direction Stream exits and through a side spillway is dissipated.
Ferner ist es aus der DE 24 34 109 A1 bekannt, den Draht durch zwei Kegeldüsen zu führen, deren erste einen Kühlmittelstrom in Laufrichtung des Drahtes auf diesen richtet, während die zweite als Gegenstromdüse arbeitet, also den Kühlmittelstrom entgegen der Laufrichtung gegen den Draht fließen lässt. Eine nach diesem Prinzip von Mitstrom und Gegenstrom arbeitende Drahtkühlvorrichtung ist ferner aus der DE-AS 1 602 356 bekannt.Furthermore, it is known from DE 24 34 109 A1, the wire to lead through two conical nozzles, the first of which is a coolant flow in the direction of the wire aimed at this while the second works as a countercurrent nozzle, so the coolant flow against the direction of flow against the wire leaves. One according to this principle of co-current and countercurrent working wire cooling device is also known from DE-AS 1 602 356 known.
Aus der DE 41 07 205 A1 ist eine Vorrichtung zum Kühlen und hydraulischen Transport von Walzstahl bekannt, die ein Kühlrohr mit einem Düsenkopf aus einem Oberteil und einem Unterteil aufweist, in welche Umleitungskanäle und Düsen eingearbeitet sind. An diese Ober- und Unterteile schließen sich ein Führungsrohroberteil und ein Führungsrohrunterteil an, und die beiden Oberteile sowie die beiden Unterteile von Düsenkopf und Führungsrohr werden durch seitlich beiderseits angesetzte Leisten mit T-förmigem Querschnitt zu einer kompakten Kühlrohreinheit verbunden.

These upper and lower parts are included Guide tube upper part and a guide tube lower part, and the both tops as well as the two lower parts of nozzle head and Guide tube are attached by laterally on both sides Bars with T-shaped cross-section to a compact cooling tube unit connected. By changing the cross-sectional dimensions These bars can be the cross-sectional dimensions change the cooling channel and adapt to different refrigerated goods.

Der Erfindung liegt die Aufgabe zugrunde, eine insbesondere zum Kühlen von Flachdrähten geeignete Kühlvorrichtung zu schaffen, die auch bei gedrängtem Aufbau eine gute Kühlleistung erbringt, sich problemlos herstellen, einfach montieren und leicht bedienen lässt. The invention is based on the object, in particular Cooling device suitable for cooling flat wires create, even with crowded construction a good cooling performance provides, easy to manufacture, easy to assemble and easy to operate.
Diese Aufgabe wird durch die im Anspruch 1 angegebenen Merkmale gelöst. Weiterbildungen der Erfindung sind in den Unteransprüchen gekennzeichnet.This object is achieved by the features specified in claim 1 solved. Further developments of the invention are in the subclaims characterized.
Die erfindungsgemäße Konstruktion sieht die Ausbildung aller wesentlichen Teile wie Düsen, Drahtführungskanal und Kühlmittelkanäle in einem einzigen relativ flachen quaderförmigen Teil vor, in welche sie entweder von einer Seite hineingearbeitet werden oder vorzugsweise als Durchbrechungen dieses flachen Teils ausgebildet werden, wozu sich insbesondere ein Drahterosionsverfahren eignet. Jedoch wäre auch ein Herausschneiden mit Laserstrahl denkbar. An dieses flache Teil können beiderseits Platten angesetzt werden, deren eine mit Öffnungen für Zuführung und Abführung des Kühlmittels versehen ist, die zu den entsprechenden Ausnehmungen im Quaderteil führen und zweckmäßigerweise mit Anschlussgewinden für die Kühlmittelschläuche versehen sind, während die andere Platte lediglich eine Abdeckplatte sein kann, die z.B. mit Hilfe eines geeigneten Verschlusses zum Einlegen des Drahtes abnehmbar ausgebildet werden kann.The construction of the invention provides the training of all essential parts such as nozzles, wire guide channel and coolant channels in a single relatively flat cuboid Part in which they either worked in from one side be or preferably as openings this be formed flat part, including in particular a Wire erosion process is suitable. However, it would also be a cut out conceivable with laser beam. At this flat part can Both sides plates are used, one with openings provided for supply and discharge of the coolant is that to the corresponding recesses in the quad part lead and expediently with connecting threads for the Coolant hoses are provided while the other plate may only be a cover plate, e.g. with help of a suitable closure for inserting the wire removable can be trained.
Praktisch ist hierbei, dass der Kühlmittelzu- und -abfluss von einer Seite her erfolgt, z.B. von hinten, während der Draht von vorne eingelegt wird, ohne dass Schläuche beim Hantieren stören. Alternativ können die Kühlmittelzu- und abführungen jedoch auch als nach oben und unten gerichtete Bohrungen im Düsenkörper verlaufen und in die entsprechenden Kanäle im Inneren des Düsenkörpers einmünden, so dass die Anschlussschläuche nicht von hinten, sondern von oben oder unten angeschlossen werden. Bei anderer Orientierung (Drehung der ganzen Anordnung um 90°) ändern sich die Richtungen entsprechend. Practical here is that the coolant inlet and outlet from one side, e.g. from behind, during the Wire is inserted from the front without hoses when handling to disturb. Alternatively, the coolant inlets and outlets but also as directed up and down holes run in the nozzle body and in the corresponding channels in the interior of the nozzle body, so that the connecting hoses not connected from behind, but from above or below become. In other orientation (rotation of the whole Arrangement by 90 °), the directions change accordingly.
Im Interesse einer gleichmäßigen Kühlwirkung eines Flachdrahtes erfolgt die Kühlmittelzuführung zweckmäßigerweise von beiden Seiten her auf den Draht über dessen volle Breite. Eine entsprechende Doppeldüse enthält dazu zwei Kühlmittelkanäle, die sich zur Erhöhung der Strömungsgeschwindigkeit in Richtung auf den Draht verjüngen und schräg auf ihn zuführen, so dass die beiden Kühlmittelströme unter einem flachen Winkel auf den Draht auftreffen. Um bei dem gedrängten Aufbau einen ausreichenden Kühlmittelfluss zu erreichen, sind erfindungsgemäß auf jeder Seite doppelte Kühlmittelzuflusskanäle vorgesehen, die parallel gespeist werden und jeweils in eine gemeinsame Kammer einmünden, die sich in Form der verjüngten Kanäle fortsetzen, die schräg auf den Draht gerichtet sind. Auch zum Abführen des Kühlmittels sind dementsprechend jeweils zwei Kanäle vorgesehen, die von einer Kühlmittel-Sammelkammer, durch welche der Drahtführungskanal hindurchführt, nach außen verlaufen.In the interest of a uniform cooling effect of a flat wire the coolant supply is expediently carried out by on both sides of the wire over its full width. A corresponding double nozzle contains two coolant channels, which is used to increase the flow velocity in Rejuvenate the direction of the wire and place it at an angle, so the two coolant flows are at a shallow angle hit the wire. At the crowded construction to achieve a sufficient flow of coolant are according to the invention Double coolant inflow channels on each side provided, which are fed in parallel and each in one joint chamber, which takes the form of the rejuvenated Continue channels that are diagonally directed towards the wire. Also for discharging the coolant are accordingly respectively two channels provided by a coolant collecting chamber, through which the wire guide channel passes, run outwards.
Zur Abdichtung des Drahtführungskanals gegen die Einlauf- und die Auslaufstelle des Drahtes sind in der Nähe dieser Stellen zweckmäßigerweise Strömungsbremsen vorgesehen, in deren Bereich Strömungswirbel entstehen, welche den Druck an den Einund Ausführungsstellen des Drahtes vermindern, um dort Leckagen entgegenzuwirken. Zusätzlich können zwischen diesen Strömungsbremsen und den Enden der Kühlvorrichtung zusätzliche Abflusskanäle als "Überläufe" zur Druckentlastung vorgesehen werden.For sealing the wire guide channel against the inlet and the outlet of the wire are near these places expediently flow brakes provided in the area Flow vortices arise which reduce the pressure on the inlet and outlet Reduce execution points of the wire to leak there counteract. In addition, between these flow brakes and the ends of the cooling device additional Outflow channels provided as "overflows" for pressure relief become.
Eine spezielle Ausgestaltung der Erfindung besteht darin, der im Gegenstrom zur Drahtführung arbeitenden Düse eine Mitstromdüse als Vorkühldüse vorzuschalten, um zu verhindern, dass bei beschichteten, etwa verzinnten Drähten, die von der Wärmebehandlung her noch flüssige Beschichtung durch den dem Draht entgegengerichteten Kühlmittelstrom wellig werden lässt. Das hier mit dem Draht fließende Kühlmittel baut einen Gegendruck auf und kühlt die Beschichtung soweit ab, dass sie erstarrt und von dem dann folgenden Gegenstrom der anderen Düse nicht mehr verformt wird. Eine solche Kombination von Mit- und Gegenstromdüsen samt zugehörigen Kühlmittelkanälen lässt sich bei der Erfindung problemlos in ein und demselben Düsenkörper ausbilden, speziell wenn dieser mit einem beiderseitig mit Platten abgedeckten Zentralteil ausgebildet wird, in welchem auch komplizierte Durchbrechungsmuster relativ einfach hergestellt werden können. Es ist auch möglich, die Dicke dieses Zentralteils an die Breite der jeweils zu kühlenden Flachdrähte anzupassen, also je nach Drahtbreite unterschiedlich breite Zentralteile vorzusehen und diese dann dementsprechend auszuwechseln, wobei die rückwärtige Platte mit den Schlauchanschlüssen beibehalten wird und auch die vordere Abdeckplatte die gleiche bleiben kann.A special embodiment of the invention is that of in countercurrent to the wire guide nozzle working a Mitstromdüse as a pre-cooling nozzle to prevent that with coated, about tinned wires, that of the Heat treatment ago still liquid coating by the Wire opposing coolant flow become wavy leaves. The coolant flowing here with the wire builds a Counterpressure and cools the coating so far that they solidified and then the following countercurrent of the other Nozzle is no longer deformed. Such a combination of Mit- and countercurrent nozzles together with associated coolant channels can be easily in the invention in one and the same Forming nozzle body, especially if this one-sided formed with plates covered central part is formed, in which also complicated opening pattern relative can be easily made. It is also possible that Thickness of this central part to the width of each to be cooled Flat wires, so different depending on the wire width provide wide central parts and then replace accordingly, with the rear plate is maintained with the hose connections and also the front cover plate can remain the same.

Die Draufsicht auf eine erste Ausführungsform der Erfindung
gemäß Fig. 1a lässt ein relativ schmales Zentralteil 2 erkennen,
welches sich an den Enden T-förmig erweitert und an welches
beiderseits Seitenplatten 4 und 6 angesetzt sind, welche
durch die T-förmigen Verbreiterungen 8 abgeschlossen werden.
Angedeutete Verschraubungen 10 halten die drei Teile zusammen.
Beiderseitige Endstücke 12 vervollständigen die Vorrichtung,
welche über Befestigungsbohrungen 14 an ein Montageteil
angeschraubt werden kann.The plan view of a first embodiment of the invention
According to FIG. 1 a, a relatively narrow
In Fig. 1b ist der das Zentralteil längs durchsetzende Drahtführungskanal
16 zu erkennen, durch den der hier nicht veranschaulichte
Draht in Richtung des Pfeiles 18 hindurchläuft.
Dabei durchläuft er eine Düse 20, welche ihn entgegen seiner
Laufrichtung mit einem Kühlmittel umspült. Das Kühlmittel
wird in Richtung der kleinen Pfeile über vier Zuflusskanäle
22a, b und 24a, b zugeführt, von denen die beiden Kanäle 22a
und 24a in eine flache Kammer 26a und die beiden anderen Kanäle
22b, 24b in eine weitere flache Kammer 26b einmünden.
Diese beiden Kammern liegen beiderseits des Drahtführungskanals
16 und münden in sich verjüngende Kühlmittelkanäle 28a
bzw. 28b, die schräg auf den Drahtführungskanal 16 zu verlaufen.
Infolge der Verjüngung erhöht sich die Strömungsgeschwindigkeit
des Kühlinittels im Sinne einer Verbesserung des
Düseneffekts. Zwischen den beiden Kammern 26a, b ist der
Drahtführungskanal 16 mit einer Strömungsbremse 30 versehen,
die einer Leckage von Strömungsmittel auf der Drahtaustrittsseite
entgegenwirkt.In Fig. 1b of the central part longitudinally passing
Die dem Draht entgegenfließende Kühlmittelströmung gelangt
schließlich in eine Sammelkammer 32, aus der nach beiden Seiten
je zwei Abflusskanäle 34a, 36a bzw. 34b, 36b wegführen,
aus denen das Kühlmittel in Richtung der kleinen Pfeile austritt.
Auch auf dieser Seite weist der Kühlmittelkanal 16 im
Anschluss an die Sammelkammer 32 eine Strömungsbremse 38 zur
Abdichtung auf. Zusätzlich sind noch Überläufe 40a, b in Form
weiterer Abflusskanäle vorgesehen.The coolant flow flowing counter to the wire passes
finally into a
Das Zentralteil 2 mit seinen verschiedenen Kanälen und Bohrungen
lässt sich relativ problemlos herstellen, da es zunächst
frei zugänglich ist und erst durch die beiderseitigen
Seitenplatten 4 und 6 abgeschlossen wird.The
In den Figuren 2a bis 2e ist eine andere Ausführungsform der
Erfindung veranschaulicht. Die Kühlmittelzu- und -abführung
zum Zentralteil 2 erfolgt hier nicht wie bei der ersten Ausführungsform
von oben und unten, sondern von der Seite bzw.
hinten über die Seitenplatte 4, die dazu entsprechende Bohrungen
als Kühlmittelkanäle enthält. Außerdem sind hier zwei
Düsen vorgesehen, von denen die eine im Mitstrom und die andere
im Gegenstrom arbeitet. Wie Fig. 2e erkennen lässt, ist
die Anordnung hier symmetrisch ausgebildet, wobei bei wiederum
in Richtung des Pfeils 18 angenommener Drahtlaufrichtung
die linke Düse als Vorkühldüse im Mitstrom und die rechte im
Gegenstrom arbeitet.FIGS. 2a to 2e show another embodiment of the invention

Wie Fig. 2c zeigt, ist das Zentralteil 2 hier wiederum als
flacher Quader mit T-förmigen Verbreiterungen 8 an den Enden
ausgebildet, zwischen welche die Seitenplatten 4 und 6 hineinpassen.
Die Verschraubungen sind hier der Übersichtlichkeit
halber nicht dargestellt.As shown in Fig. 2c, the
Die Anordnung der einzelnen Elemente ist am besten aus Figur
2e ersichtlich. Der in Richtung des Pfeils 18 im Drahtführungskanal
16 durch die Vorrichtung laufende Draht durchläuft
zunächst die Mitstromdüse 42, wo er von beiden Seiten vorgekühlt
wird. Das Kühlmittel tritt durch die Öffnungen 23c und
23d in der Seitenplatte 4 in die Zuflusskanäle 23a bzw. 23b
ein und durchläuft die sich verjüngenden Kühlmittelkanäle
28a, 28b, aus denen es mit der Drahtlaufrichtung austritt.
Wiederum sind gegen Kühlmittelleckagen am Einlaufende eine
Strömungsbremse 30 sowie Überlaufkanäle 40a, 40b vorgesehen,
die mit Öffnungen 40c, 40d in der Seitenplatte 4 kommunizieren,
aus denen Kühlmittel abgeführt werden kann. Die an dieser
Düse erfolgende Vorkühlung empfiehlt sich bei beschichteten
Drähten, deren Beschichtung wegen der hohen Drahttemperatur
noch nicht erstarrt ist. Der aus der Düse 42 austretende,
mit der Drahtlaufrichtung geführte Kühlmittelstrom kühlt die
Beschichtung soweit ab, dass sie bei der anschließenden Gegenstromkühlung
durch die Düse 20 nicht mehr verformt wird.The arrangement of the individual elements is best from FIG
2e can be seen. The in the direction of
Der Aufbau beider Düsen und zugehörigen Kanäle ist hier spiegelsymmetrisch.
Das Kühlmittel tritt durch die Öffnungen 22c,
22d in der Seitenplatte 4 in die beiderseitigen Zuflusskanäle
22a, 22b ein und durchläuft wiederum sich verjüngende Kühlmittelkanäle
28a und 28b, um dann beiderseits auf den im
Drahtführungskanal 16 ankommenden Draht aufzuströmen und diesen
wie im ersten Ausführungsbeispiel im Gegenstrom zu kühlen.
Bei dem hier veranschaulichten Ausführungsbeispiel sind
der Übersichtlichkeit halber nur einfache Zulaufkanäle gezeigt,
jedoch können ebenso wie beim ersten Ausführungsbeispiel
auch Doppelkanäle vorgesehen werden. Dagegen sind auf
jeder Seite drei Kühlmittelabflusskanäle 35a bzw. 35b gezeichnet,
aus welchen das Kühlmittel durch die Öffnungen 35c,
35d in der Seitenplatte 4 austreten und in den Kreislauf zurückgeführt
werden kann.The structure of both nozzles and associated channels is here mirror-symmetrical.
The coolant passes through the
Auch am Auslaufende des Drahtes sind eine Strömungsbremse 30
und Überlaufkanäle 40a, 40b vorgesehen. Die hier nicht dargestellte
Befestigung der einzelnen Teile aneinander kann in
zweckmäßiger Weise erfolgen, so dass beispielsweise die vordere
Seitenplatte 6 zum Einlegen des Drahtes in das Zentralteil
2 leicht abgenommen und anschießend wieder befestigt
werden kann. Ein geeigneter Schnellverschluss könnte hier
vorgesehen werden. Auch die Befestigung des Zentralteils 2 an
der Seitenplatte 4, an welcher die Kühlmittelanschlüsse vorgesehen
sind, könnte so gestaltet werden, dass das Zentralteil
ohne Schwierigkeiten ausgetauscht werden kann, etwa wenn
für unterschiedlich breite Drähte verschieden dicke Zentralteile
vorgesehen sind.Also at the outlet end of the wire are a flow brake 30th
