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.
The present invention relates to a winding layer for rod-shaped rolling stock, with a hollow shaft, a laying tube holder and a laying tube for the rod-shaped rolling stock.
  • wherein the hollow shaft is rotatably supported about a shaft axis in at least one secondary bearing and one main bearing,
  • the sub-bearing and the main bearing being axially distanced,
  • the laying tube holder is connected to the hollow shaft in a rotationally fixed manner, projects beyond the main bearing and carries the laying tube,
  • wherein the laying tube has an inlet end and an outlet end, the inlet end is aligned with the shaft axis and the outlet end is radially distanced from the shaft axis.

Ein derartiger Windungsleger ist allgemein bekannt. Beispielhaft wird auf die EP 0 679 453 A1 verwiesen.Such a winding layer is generally known. Exemplary reference is made to EP 0 679 453 A1.

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 winding layer rotates around the shaft axis. At the same time, the winding layer is along the shaft axis the rod-shaped rolling stock is fed at the rolling stock speed. The rolling stock runs into the inlet end of the laying tube and emerges tangentially from the outlet end so that it is in shape a series of rings or turns on a conveyor belt can be filed. The peripheral speed of the outlet end, which are proportional to the speed and radial distance the outlet end of the shaft axis corresponds approximately the rolling stock speed.

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 winding layer experiences in the rest state with horizontally running A deflection due to gravity. This deflection essentially determines the resonance frequency. The resonance frequency limits the speed and thus indirectly also the maximum possible rolling stock speed. The lower the gravity-related, the higher the resonance frequency Deflection of the laying tube holder in the idle state is.

Die Aufgabe der vorliegenden Erfindung besteht darin, einen Windungsleger derart weiterzuentwickeln, daß er eine möglichst geringe schwerkraftbedingte Durchbiegung und damit eine möglichst große Resonanzfrequenz aufweist.The object of the present invention is a Winding layer to evolve in such a way that it is as possible low deflection due to gravity and thus a has the largest possible resonance frequency.

Die Aufgabe wird dadurch gelöst, daß der Legerohrhalter zumindest teilweise aus einem Material besteht, das eine geringere Dichte als Stahl aufweist.The object is achieved in that the laying tube holder at least partially made of a material that is less Has density than steel.

Als Materialien kommen insbesondere Leichtmetalle, z. B. Aluminium und Magnesium, oder Kunststoffe, insbesondere faserverstärkte Kunststoffe, in Frage.As materials come in particular light metals, e.g. B. aluminum and magnesium, or plastics, especially fiber-reinforced Plastics, in question.

Der Legerohrhalter weist üblicherweise ein Anschlußstück zum drehfesten Verbinden mit der Hohlwelle, ein im wesentlichen rotationssymmetrisches Mittelstück, eine am Mittelstück angeordnete Tragstruktur für das Legerohr und eine Ausgleichsstruktur zum Ausgleichen von Unwuchten auf. Zumindest die Tragstruktur sollte aus dem Material bestehen, das eine geringere Dichte als Stahl aufweist.The laying tube holder usually has a connector for non-rotatable connection with the hollow shaft, a substantially rotationally symmetrical center piece, one arranged on the center piece Support structure for the laying pipe and a compensation structure to compensate for unbalance. At least that Support structure should consist of the material that is a lesser Has density than steel.

Durch die Verwendung von Leichtmetall oder faserverstärktem Kunststoff im Überhangbereich des Windungslegers, also jenseits des Hauptlagers, wird die schwerkraftbedingte Durchbiegung aber selbst dann deutlich verringert, wenn auch das noch biegebeanspruchte Mittelstück und evtl. sogar das Anschlußstück aus Leichtmetall gefertigt sind. Denn jenseits des Hauptlagers ist die Krümmung der Biegelinie relativ gering, so daß die schwerkraftbedingte Durchbiegung im wesentlichen von der Biegelinienneigung der Hohlwelle am Hauptlager bestimmt wird. Der niedrigere Elastizitätsmodul der tragenden Teile im Überhangbereich erhöht deshalb die schwerkraftbedingte Durchbiegung nur geringfügig.Through the use of light metal or fiber reinforced Plastic in the overhang area of the winding layer, i.e. beyond of the main bearing, the deflection caused by gravity but significantly reduced even if that too bend-stressed middle piece and possibly even the connecting piece are made of light metal. Because beyond Main bearing, the curvature of the bending line is relatively small, so that the gravity-induced deflection essentially determined by the bending line inclination of the hollow shaft at the main bearing becomes. The lower modulus of elasticity of the load-bearing Parts in the overhang area therefore increase the gravity-related Deflection only slight.

Auch das Legerohr kann aus einem Material bestehen, das eine geringere Dichte als Stahl aufweist. Gleiches gilt 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. Das Legerohr kann z. B. aus einem Leichtmetall bestehen und auf seiner Innenseite eine Keramikschicht aufweisen.The laying tube can also be made of a material that is one has lower density than steel. The same applies to one guide extension subordinate to the laying tube. Come here due to the thermal stress on these parts in particular ceramic materials, possibly also composite materials Light metal and ceramic, in question. The laying tube can e.g. B. consist of a light metal and one on the inside Have ceramic layer.

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 stock 1 is by means of a Winding layer 2 in the form of a series of rings or turns 3 stored on a conveyor belt 4. For this, the Rolling stock 1 the winding layer 2 at a rolling stock speed vW fed. The winding layer 2 rotates at the same time at a speed n about a shaft axis 5. The winding layer 2 is in a known manner by means of a motor 6 a gear 7, usually a reversing gear 7, driven.

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 FIG. 2, the winding layer 2 has a hollow shaft 8, one Laying tube holder 9 and 10 laying tube. The hollow shaft 8 is stored in a sub-warehouse 11 and a main warehouse 12 in this way is that the hollow shaft 8 is rotatable about the shaft axis 5 is. The sub bearing 11 and the main bearing 12 are axially distanced.

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 laying tube holder 9 projects beyond the main bearing 12. He has a connector 13, z. B. a connecting flange 13, and an essentially rotationally symmetrical center piece 14 on. By means of the connector 13, the laying tube holder 9 rotatably connected to the hollow shaft 8. With the middle piece 14 are a support plate 15, support plates 16, 17 and a compensating structure 18 connected.

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 support plate 15 rotates with the laying tube 10. It has connection eyes 19 on which holding elements 20 are attached. By means of the holding elements 20 carries the support plate 15 and thus also the laying tube holder 9 the laying tube 10. The support plates 16, 17 support the support plate 15 axially forwards and backwards from. The support plate 15, the support plates 16, 17 and the holding elements 20 together form one arranged on the center piece 14 Support structure for the laying pipe 10. The compensation structure 18 is used to compensate for the structure and the laying pipe 10 caused unbalance.

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 laying tube 10 has an inlet end 21 and an outlet end 22 on. Describes between the inlet end 21 and the outlet end 22 the laying tube 10 is a three-dimensionally curved guideway for the rolling stock 1. The inlet end 21 is aligned the shaft axis 5. The outlet end 22 has from the shaft axis 5 a radial distance d. The rolling stock 1 runs the shaft axis 5 along, enters the laying pipe 10 at the inlet end 21 in and at the outlet end 22 out of the laying tube 10.

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 speed n and the distance d, the outlet end runs 22 with a peripheral speed vU around the shaft axis 5 um. The peripheral speed vU corresponds to the Roll speed vW. The outlet end 22 thus describes a circle 23 around the shaft axis 5. The laying tube 10 is a Subordinate extension 24. The guide extension 24 serves in particular to properly place the last one Turns 3 on the conveyor belt 4.

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.In the idle state, the winding layer 2 points in the horizontal direction Shaft axis 5 of the winding layer 2 according to FIG. 3 a deflection D due to gravity. The gravity-related Deflection D is clear in Figure 3 half exaggerated. The gravity-related Deflection D determines the resonance frequency that the coil layer 2 has in operation. The resonance frequency is limited the speed n and thus indirectly the maximum possible rolling stock speed vW. The resonance frequency is the higher the lower the deflection caused by gravity D of the winding layer 2 is.

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 deflection D caused by gravity and so the resonance frequency and thus indirectly the maximum to increase possible rolling stock speed vW Coil layer 2 not consistently of steel. In particular, there is the laying tube holder 9 is at least partially made of one material, which has a lower density than steel. As materials come especially light metals, e.g. B. aluminum and magnesium, in question. Possibly. can also be a fiber reinforced Plastic are used. This can be achieved that the gravity-induced deflection D of the winding layer 2 by more than half compared to gravity Deflection D 'of a structurally identical coil layer made of steel.

In erster Linie sollten zumindest die nicht biegebeanspruchten Teile des Legerohrhalters 9 aus Leichtmetall gefertigt werden. Zumindest die Tragstruktur sollte also aus Leichtmetall bestehen. First and foremost, at least those that are not subjected to bending should Parts of the laying tube holder 9 are made of light metal become. At least the supporting structure should be made of light metal consist.

Auch das Legerohr 10 und ein ggf. diesem nachgeordneter Führungsfortsatz 24 können zumindest teilweise aus einem Material besteht, das eine geringere Dichte als Stahl aufweist. Bei diesen Teilen kommen aufgrund der thermischen Beanspruchung insbesondere keramische Werkstoffe, ggf. auch Verbundwerkstoffe aus Leichtmetall und Keramik, in Frage. Das Legerohr 10 kann z. B. aus einem Leichtmetall bestehen und auf seiner Innenseite eine Keramikschicht aufweisen.Also the laying tube 10 and a guide extension that may be arranged after this 24 can be at least partially made of one material exists, which has a lower density than steel. At these parts come due to the thermal stress in particular ceramic materials, possibly also composite materials made of light metal and ceramic, in question. The laying pipe 10 can e.g. B. consist of a light metal and on it Have a ceramic layer on the inside.

Die schwerkraftbedingte Durchbiegung wird im wesentlichen von der Biegelinienneigung der Hohlwelle am Hauptlager bestimmt. Daher kann ggf. auch das Mittelstück 14, evtl. sogar das Anschlußstück 13, aus Leichtmetall bestehen.The deflection caused by gravity is essentially of the bending line inclination of the hollow shaft at the main bearing. Therefore, if necessary, the middle piece 14, possibly even the connecting piece 13, made of light metal.

Gemäß Ausführungsbeispiel besteht nur die Hohlwelle 8 aus Stahl. Das Tragblech 15, die Stützbleche 16, 17, die Ausgleichsstruktur 18, das Mittelstück 14 und sogar das Anschlußstück 13 bestehen aus Leichtmetall. Das Legerohr 10 besteht aus Leichtmetall und weist auf seiner Innenseite eine Keramikschicht auf. Der Führungsfortsatz 24 besteht in seinem thermisch und mechanisch beanspruchten Teil aus Keramik und im übrigen aus Leichtmetall. According to the exemplary embodiment, only the hollow shaft 8 consists Steel. The support plate 15, the support plates 16, 17, the compensating structure 18, the center piece 14 and even the connector 13 are made of light metal. The laying pipe 10 is made made of light metal and has an inside Ceramic layer on. The guide extension 24 consists in his thermally and mechanically stressed part made of ceramic and otherwise made of light metal.
