Description
Die vorliegende Erfindung betrifft einen Windungsleger für stabförmiges Walzgut, mit einer Hohlwelle, einem Legerohrhalter und einem Legerohr für das stabförmige Walzgut,
- wobei die Hohlwelle zumindest in einem Nebenlager und einem Hauptlager um eine Wellenachse drehbar gelagert ist,
- wobei das Nebenlager und das Hauptlager axial distanziert sind,
- wobei der Legerohrhalter drehfest mit der Hohlwelle verbunden ist, über das Hauptlager hinausragt und das Legerohr trägt,
- wobei das Legerohr ein Einlaßende und ein Auslaßende aufweist, das Einlaßende mit der Wellenachse fluchtet und das Auslaßende von der Wellenachse radial distanziert ist, und
- wobei der Legerohrhalter zumindest teilweise auf einem Material besteht, das eine geringere Dichte als Stahl aufweist.
- wherein the hollow shaft is rotatably mounted about a shaft axis at least in a sub-camp and a main bearing,
- wherein the sub-camp and the main camp are axially spaced,
- wherein the laying tube holder is non-rotatably connected to the hollow shaft, projects beyond the main bearing and carries the laying tube,
- the laying tube having an inlet end and an outlet end, the inlet end aligned with the shaft axis and the outlet end radially spaced from the shaft axis, and
- wherein the laying tube holder at least partially on a material which has a lower density than steel.
Ein solcher Windungsleger ist durch die EP 0 779 115 A 1 bekanntgeworden.Such a coiler has become known from EP 0 779 115 A 1.
Im Betrieb rotiert der Windungsleger um die Wellenachse. Gleichzeitig wird dem Windungsleger entlang der Wellenachse das stabförmige Walzgut mit Walzgutgeschwindigkeit zugeführt. Das Walzgut läuft in das Einlaßende des Legerohres ein und tritt tangential aus dem Auslaßende aus, so daß es in Form einer Serie von Ringen bzw. Windungen auf einem Transportband abgelegt werden kann. Die Umfangsgeschwindigkeit des Auslaßendes, die proportional zur Drehzahl und zum radialen Abstand des Auslaßendes von der Wellenachse ist, entspricht etwa der Walzgutgeschwindigkeit.In operation, the Windungsleger rotates about the shaft axis. At the same time, the Winding layer along the shaft axis the rod-shaped rolling stock with Walzgutgeschwindigkeit fed. The rolling stock enters the inlet end of the laying tube and exits tangentially from the outlet end so that it is in the form of a series of Rings or turns can be stored on a conveyor belt. The Peripheral speed of the outlet end, which is proportional to the speed and the Radial distance of the outlet end of the shaft axis is approximately equal to Rolling stock.
Der Windungsleger erfährt im Ruhezustand bei horizontal verlaufender Wellenachse eine schwerkraftbedingte Durchbiegung. Diese Durchbiegung bestimmt im wesentlichen die Resonanzfrequenz. Die Resonanzfrequenz begrenzt die Drehzahl und damit indirekt auch die maximal mögliche Walzgutgeschwindigkeit. Die Resonanzfrequenz ist um so höher, je geringer die schwerkraftbedingte Durchbiegung des Legerohrhalters im Ruhezustand ist.The Windungsleger undergoes at rest with horizontally extending shaft axis a gravity-induced deflection. This deflection is determined in essentially the resonant frequency. The resonance frequency limits the speed and thus indirectly the maximum possible rolling stock speed. The Resonance frequency is higher, the lower the gravitational deflection of the laying tube holder is at rest.
Der Efindung liegt daher die Aufgabe zugrunde, einen Windungslegerder eingangs genannten Art derart weiterzuentwickeln, daß er eine möglichst geringe schwerkraftbedingte Durchbiegung und damit eine möglichst große Resonanzfrequenz aufweist.The Efindung therefore has the object, a Windungslegerder the beginning mentioned type such that it has the lowest possible Gravity-induced deflection and thus the highest possible resonance frequency having.
Die Aufgabe wird erfindungsgemäß dadurch gelöst, daß auch das Legerohr aus einem Leichtmetall, z. B. Aluminium und Magnesium, besteht und auf seiner Innenseite eine Keramikschicht aufweist. Somit besteht nicht nur der Legerohrhalter, sondem auch das Legerohr selbst aus einem Material, das eine geringere Dichte als Stahl besitzt.The object is achieved in that the laying pipe a light metal, for. As aluminum and magnesium, and on its inside has a ceramic layer. Thus, not only the laying tube holder, but also the laying pipe itself made of a material that has a lower density as steel possesses.
Gleiches giltnach einer Ausgestaltung der Erfndung für einen dem Legerohr nachgeordneten Führungsfortsatz. Hier kommen aufgrund der thermischen Beanspruchung dieser Teile insbesondere keramische Werkstoffe, ggf. auch Verbundwerkstoffe aus Leichtmetall und Keramik, in Frage. The same applies to an embodiment of the invention for a laying tube downstream leadership extension. Here come due to the thermal stress these parts in particular ceramic materials, possibly also composite materials made of light metal and ceramic, in question.

Gemäß Figur 1 wird ein stabförmiges Walzgut 1 mittels eines Windungslegers 2 in
Form einer Serie von Ringen bzw. Windungen 3 auf einem Transportband 4 abgelegt.
Hierzu wird das Walzgut 1 dem Windungsleger 2 mit einer Walzgutgeschwindigkeit
vW zugeführt. Gleichzeitig rotiert der Windungsleger 2 mit einer Drehzahl n
um eine Wellenachse 5. Der Windungsleger 2 wird dabei in bekannter Weise mittels
eines Motors 6 über ein Getriebe 7, üblicherweise ein Umlenkgetriebe 7, angetrieben. According to Figure 1, a rod-shaped rolling 1 by means of a
Gemäß Figur 2 weist der Windungsleger 2 eine Hohlwelle 8, einem
Legerohrhalter 9 und Legerohr 10 auf. Die Hohlwelle 8 ist
in einem Nebenlager 11 und einem Hauptlager 12 derart gelagert
ist, daß die Hohlwelle 8 um die Wellenachse 5 drehbar
ist. Das Nebenlager 11 und das Hauptlager 12 sind axial distanziert.According to Figure 2, the Windungsleger 2 has a
Der Legerohrhalter 9 ragt über das Hauptlager 12 hinaus. Er
weist ein Anschlußstück 13, z. B. einen Anschlußflansch 13,
und ein im wesentlichen rotationssymmetrisches Mittelstück 14
auf. Mittels des Anschlußstücks 13 ist der Legerohrhalter 9
drehfest mit der Hohlwelle 8 verbunden. Mit dem Mittelstück
14 sind ein Tragblech 15, Stützbleche 16, 17 und eine Ausgleichsstruktur
18 verbunden.The
Das Tragblech 15 läuft mit dem Legerohr 10 um. Es weist Anschlußaugen
19 auf, an denen Halteelemente 20 befestigt sind.
Mittels der Halteelemente 20 trägt das Tragblech 15 und damit
auch der Legerohrhalter 9 das Legerohr 10. Die Stützbleche
16, 17 stützen das Tragblech 15 axial nach vorne und hinten
ab. Das Tragblech 15, die Stützbleche 16, 17 und die Halteelemente
20 bilden zusammen eine am Mittelstück 14 angeordnete
Tragstruktur für das Legerohr 10. Die Ausgleichsstruktur
18 dient zum Ausgleichen der von der Tragstruktur und dem Legerohr
10 verursachten Unwuchten.The
Das Legerohr 10 weist ein Einlaßende 21 und ein Auslaßende 22
auf. Zwischen dem Einlaßende 21 und dem Auslaßende 22 beschreibt
das Legerohr 10 eine dreidimensional gekrümmte Führungsbahn
für das Walzgut 1. Das Einlaßende 21 fluchtet mit
der Wellenachse 5. Das Auslaßende 22 hat von der Wellenachse
5 einen radialen Abstand d. Das Walzgut 1 läuft die Wellenachse
5 entlang, tritt am Einlaßende 21 in das Legerohr 10
ein und am Auslaßende 22 aus dem Legerohr 10 aus.The
Aufgrund der Drehzahl n und des Abstandes d läuft das Auslaßende
22 mit einer Umfangsgeschwindigkeit vU um die Wellenachse
5 um. Die Umfangsgeschwindigkeit vU korrespondiert mit der
Walzgutgeschwindigkeit vW. Das Auslaßende 22 beschreibt somit
einen Kreis 23 um die Wellenachse 5. Dem Legerohr 10 ist ein
Führungsfortsatz 24 nachgeordnet. Der Führungsfortsatz 24
dient insbesondere dem ordnungsgemäßen Ablegen der letzten
Windungen 3 auf dem Transportband 4.Due to the rotational speed n and the distance d, the outlet end runs
22 at a peripheral speed vU about the
Im Ruhezustand weist der Windungsleger 2 bei horizontal verlaufender
Wellenachse 5 der Windungsleger 2 gemäß Figur 3 eine
schwerkraftbedingte Durchbiegung D auf. Die schwerkraftbedingte
Durchbiegung D ist dabei in Figur 3 der Deutlichkeit
halber stark übertrieben dargestellt. Die schwerkraftbedingte
Durchbiegung D bestimmt die Resonanzfrequenz, die der Windungsleger
2 im Betrieb aufweist. Die Resonanzfrequenz begrenzt
die Drehzahl n und damit indirekt auch die maximal
mögliche Walzgutgeschwindigkeit vW. Die Resonanzfrequenz ist
dabei um so höher, je geringer die schwerkraftbedingte Durchbiegung
D des Windungslegers 2 ist.At rest, the
Um die schwerkraftbedingte Durchbiegung D zu verringern und
so die Resonanzfrequenz und damit indirekt auch die maximal
mögliche Walzgutgeschwindigkeit vW zu erhöhen, besteht der
Windungsleger 2 nicht durchgängig aus Stahl. Insbesondere besteht
der Legerohrhalter 9 zumindest teilweise aus einem Material,
das eine geringere Dichte als Stahl aufweist. Als Materialien
kommen insbesondere Leichtmetalle, z. B. Aluminium
und Magnesium, in Frage. Ggf. kann auch ein faserverstärkter
Kunststoff verwendet werden. Dadurch kann erreicht werden,
daß die schwerkraftbedingte Durchbiegung D des Windungslegers
2 um mehr als die Hälfte gegenüber der schwerkraftbedingten
Durchbiegung D' eines konstruktiv identischen Windungslegers
aus Stahl reduziert wird.To reduce the gravitational deflection D and
so the resonance frequency and thus indirectly the maximum
consists of increasing the possible rolling stock speed
In erster Linie sollten zumindest die nicht biegebeanspruchten
Teile des Legerohrhalters 9 aus Leichtmetall gefertigt
werden. Zumindest die Tragstruktur sollte also aus Leichtmetall
bestehen. In the first place, at least those should not be bent

Auch das Legerohr 10 und ein ggf. diesem nachgeordneter Führungsfortsatz

diesen Teilen kommen aufgrund der thermischen Beanspruchung

Die schwerkraftbedingte Durchbiegung wird im wesentlichen von

the bending line inclination of the hollow shaft on the main bearing determined.
