Definitions
- the invention relates to a roller straightening machine for straightening profiled rolling stock, with offset top and bottom, straightening rollers supporting shafts, which are mounted on the drive side and temporarily supported on the operator side by an adjustable support element in the direction of the straightening force on a housing part.
- Roller straightening machines with such floating bearing shafts offer the great advantage that they are freely accessible on the operator side for changing the leveling rollers.
- the high straightening forces that occur, especially when straightening large beams lead to a bending of the supporting shafts, so that a clear straightening process is no longer possible.
- each support shaft on the operator side with an elongated bearing journal which is provided with a support bearing which in turn is enclosed by a bearing sleeve.
- This bearing sleeve and thus the support bearing are supported in the direction of the downward directional force by a support designed as a pivot lever, which partially surrounds the bearing sleeve with a half-shell.
- the swivel lever is pivotally mounted on two eccentrics of an actuating shaft.
- the eccentrics allow the pivoting lever to be adjusted between two dead center positions, namely in a vertical support position and in an expansion position which causes the half-shell to be lifted off the bearing sleeve, which allows the pivoting lever to be pivoted outwards by means of hydraulic cylinders or to move the overall support sideways.
- the invention is therefore based on the object in a straightening machine of the type mentioned with simple means variable support of the free, i.e. provide operator-side ends of the support shafts.
- a preferred embodiment of the invention provides that the head ends of the adjusting spindles facing the support shafts have at least two support rollers in a yoke. These enable a support that fully meets the requirements if they are arranged at an angle of 60 ° to one another.
- the yoke assigned to the two support rollers supports the rigidity of the roller bearing.
- the support rollers on the roller bushes of the support shafts are assigned a tread, which can preferably be provided by a race. It is thus possible in a simple manner to provide a hardened running surface for the support rollers, namely by appropriate heat treatment of the running ring or by a suitable choice of material. It is advisable to equip the support shafts with a conical mounting or roller bushing, which offers the race a better fit compared to a cylindrical mounting sleeve or bushing and also keeps the games less.
- running surfaces are advantageously shielded, for example by covering the pair of support rollers, they can be kept free of sinter.
- the straightening machine 1 shown in FIG. 1 accommodates four and three support shafts 3 and 4, which are offset to the bottom, in its housing 2 at the top; On the inlet and outlet sides there is also a further supporting shaft 5 (see FIG. 2).
- the upper and lower support shafts 3, 4 and 5 are mounted in a first bearing 7 on the drive side 6 and at a distance therefrom in a second bearing 8 in the housing 2, which essentially consists of side stands 9 and cross members 10 screwed to them.
- Both the upper and the lower support shafts 3, 4 are driven by motors 11 and auxiliary motors 12, the weaker auxiliary motor 12 each driving the lower support shafts 4 is assigned in order to enable a towing speed which is easier to introduce the leveling material and is below the working speed.
- adjusting spindles 14 connected to the housing 2 are arranged on the operating side 13 of the straightening machine 1. These can be set continuously against the free ends of the support shafts by means of a worm drive 16 actuated by a motor 15, of which the worm wheel 17 can be seen in FIG. 1 and the worm shaft 18 in FIG. 2, so that the support shafts 3, 4 are supported on both sides during the straightening operation, namely by the pitch-side bearings 7, 8 and the operator-side adjustment spindles 14.
- a symmetrical arrangement of these support points can be achieved, which results in a central feeding of the profiles to be straightened by the straightening rollers 3, 4 arranged on the support shafts 3, 4 20 allows; the transport of the profiles 20 on the feed roller table is thus improved.
- the head ends of the adjusting spindles 14 facing the support shafts 3, 4 are provided with a yoke 21 in which two support rollers 23 bearing against running surfaces 22 of the support shafts 3, 4 are at an angle 24 of 60 ° are stored to each other.
- the tread 22 is made available by a race 25 which is arranged in a conical mounting bush 26 which also carries the straightening rollers 19.
- a hydraulic clamping nut arranged below a protective hood 27 serves to pull the mounting bushing 26 onto the supporting shafts 3, 4.
- the lower part of the frame or housing 2 of the straightening machine 1 accommodates two adjusting spindles 28, 29 which are driven by a gear motor 32 via worm wheels 30, 31 and are adjustable in height, so that the straightening plane on the one hand when changing to profiles of another size and others can be adapted to the roller tables of the rolling mill.
- the worm drives 16, which enable a large stroke together with a high load-bearing capacity, from above and below against the free ends of the supporting shafts 3, 4 thus ensure, despite flying support, a bilateral during straightening operation, which is also used for preloading and optimizing the gap width Support of the support shafts 3, 4, which in particular allows the straightening of large and heavy profiles 20, since the support shafts 3, 4 can only bend as little as possible. This is promoted by the transmission of the supporting force to the housing 2 via the two supporting rollers 23 arranged in the yoke 21 at an angle of 60 ° to one another.
- the adjusting spindles 14 can quickly be sufficiently far from the running surfaces 22, i.e. move the support shafts 3, 4 away so that there is sufficient free space on the operating side 13 to replace the old with a new set of straightening rollers 19.

Abstract
Description
Die Erfindung betrifft eine Rollenrichtmaschine zum Richten von profiliertem Walzgut, mit versetzt zueinander angeordneten oberen und unteren, Richtrollen aufweisenden Tragwellen, die antriebsseitig gelagert und bedienungsseitig temporär durch ein verstellbares Stützelement in Richtung der Richtkraft an einem Gehäuseteil abgestützt sind.The invention relates to a roller straightening machine for straightening profiled rolling stock, with offset top and bottom, straightening rollers supporting shafts, which are mounted on the drive side and temporarily supported on the operator side by an adjustable support element in the direction of the straightening force on a housing part.
Rollenrichtmaschinen mit derartig fliegend gelagerten Tragwellen bieten den großen Vorteil, daß sie bedienungsseitig zum Richtrollenwechsel frei zugänglich sind. Allerdings führen die auftretenden hohen Richtkräfte, insbesondere beim Richten großer Träger, zu einer Aufbiegung der Tragwellen, so daß ein eindeutiger Richtprozeß nicht mehr möglich ist. Aus der DE 36 16 699 A ist es daher bekannt, jede Tragwelle bedienungsseitig mit einem verlängerten Lagerzapfen auszubilden, der mit einem Stützlager versehen ist, das seinerseits von einer Lagerhülse umschlossen wird. Diese Lagerhülse und damit das Stützlager sind in Richtung der nach unten wirkenden Richtkraft durch eine als Schwenkhebel ausgebildete Stütze abgestützt, die mit einer Halbschale die Lagerhülse teilweise umfaßt.Roller straightening machines with such floating bearing shafts offer the great advantage that they are freely accessible on the operator side for changing the leveling rollers. However, the high straightening forces that occur, especially when straightening large beams, lead to a bending of the supporting shafts, so that a clear straightening process is no longer possible. From DE 36 16 699 A it is therefore known to design each support shaft on the operator side with an elongated bearing journal which is provided with a support bearing which in turn is enclosed by a bearing sleeve. This bearing sleeve and thus the support bearing are supported in the direction of the downward directional force by a support designed as a pivot lever, which partially surrounds the bearing sleeve with a half-shell.
Der Schwenkhebel ist auf zwei Exzentern einer Stellwelle schwenkbar gelagert. Die Exzenter erlauben es, den Schwenkhebel zwischen zwei Totpunktlagen zu verstellen, und zwar in eine senkrechte Stützlage und eine das Abheben der Halbschale von der Lagerhülse bewirkende Ausbaulage, die es erlaubt, den Schwenkhebel mittels Hydraulikzylindern nach außen wegzuschwenken oder die Stütze insgesamt seitlich zu verschieben. Um die temporäre Abstützung, nämlich während des Richtbetriebes, zu erreichen, ist somit ein großer baulicher Aufwand erforderlich, und bei einer als Schwenkhebel ausgebildeten Stütze muß dieser zudem ein Exzenter zugeordnet werden, der die beiden Totpunktlagen ermöglicht, wobei die Exzentrizität der Höhenverstellung der Halbschale entspricht, die zum Abschwenken des Schwenkhebels samt Halbschale von der Lagerhülse des Stützlagers kinematisch erforderlich ist.The swivel lever is pivotally mounted on two eccentrics of an actuating shaft. The eccentrics allow the pivoting lever to be adjusted between two dead center positions, namely in a vertical support position and in an expansion position which causes the half-shell to be lifted off the bearing sleeve, which allows the pivoting lever to be pivoted outwards by means of hydraulic cylinders or to move the overall support sideways. In order to achieve the temporary support, namely during the straightening operation, a great deal of structural effort is required, and in the case of a support designed as a pivot lever, an eccentric must also be assigned, which enables the two dead center positions, the eccentricity corresponding to the height adjustment of the half-shell, which is kinematically required for pivoting the pivot lever together with the half-shell from the bearing sleeve of the support bearing.
Der Erfindung liegt daher die Aufgabe zugrunde, bei einer Richtmaschine der eingangs genannten Art mit einfachen Mitteln ein variable Abstützung der freien, d.h. bedienungsseitigen Enden der Tragwellen vorzusehen.The invention is therefore based on the object in a straightening machine of the type mentioned with simple means variable support of the free, i.e. provide operator-side ends of the support shafts.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß an der Bedienungsseite von oben bzw. unten gegen die Tragwellen anstellbare Spindeln angeordnet sind. Damit läßt sich im Gegensatz zur bekannten Ausführung nicht nur eine Verstellung der Abstützung zum Zwecke des Ausbaus der Tragwellen bzw. Richtrollen erreichen, sondern aufgrund der Anstellbarkeit der Spindeln bzw. Stützelemente auf einfache Weise gleichzeitig auch eine Vorspannung der Tragwellen und eine Optimierung der Spaltweite beim Richten ermöglichen. Die Spindel läßt sich, beispielsweise über einen Schneckenantrieb oder hydraulisch, stufenlos anstellen, und um die Bedienungsseite zum Ausbau freizumachen, lassen sich die Spindeln entsprechend dem benötigten Freiraum linear von den Tragwellen entfernen, d.h. gezielt von diesen absenken bzw. abheben. Der minimal notwendige Hub ergibt sich hierbei aus der Notwendigkeit, beim Wechsel die Richtrollen bzw. -scheiben an den Stützrollen vorbeiführen zu können.This object is achieved in that on the operating side from above or below adjustable spindles are arranged against the support shafts. In contrast to the known design, it is not only possible to adjust the support for the purpose of removing the support shafts or straightening rollers, but also to preload the support shafts and optimize the gap width when straightening due to the adjustability of the spindles or support elements enable. The spindle can be adjusted continuously, for example via a worm drive or hydraulically, and in order to clear the operating side for removal, the spindles can be linearly removed from the support shafts according to the required clearance, i.e. selectively lower or lift them off. The minimum necessary stroke results from the necessity to be able to guide the straightening rollers or discs past the support rollers when changing.
Eine bevorzugte Ausgestaltung der Erfindung sieht vor, daß die den Tragwellen zugewandten Kopfenden der Anstellspindeln in einem Joch mindestens zwei Stützrollen aufweisen. Diese ermöglichen eine den Anforderungen völlig entsprechende Abstützung, wenn sie unter einem Winkel von 60° zueinander angeordnet sind. Das den beiden Stützrollen zugeordnete Joch unterstützt die Steifigkeit der Rollenlagerung.A preferred embodiment of the invention provides that the head ends of the adjusting spindles facing the support shafts have at least two support rollers in a yoke. These enable a support that fully meets the requirements if they are arranged at an angle of 60 ° to one another. The yoke assigned to the two support rollers supports the rigidity of the roller bearing.
Nach einem Vorschlag der Erfindung ist den Stützrollen auf den Rollenbuchsen der Tragwellen eine Lauffläche zugeordnet, die vorzugsweise von einem Laufring bereitgestellt werden kann. Damit ist es in einfacher Weise möglich, für die Stützrollen eine gehärtete Lauffläche vorzusehen, nämlich durch eine entsprechende Wärmebehandlung des Laufringes bzw. durch eine geeignete Materialauswahl. Hierbei empfiehlt es sich, die Tragwellen mit einer konischen Montage- bzw. Rollenbuchse zu bestücken, die dem Laufring gegenüber einer zylindrischen Montagehülse bzw. -buchse einen besseren Sitz bietet und zudem die Spiele geringer hält.According to a proposal of the invention, the support rollers on the roller bushes of the support shafts are assigned a tread, which can preferably be provided by a race. It is thus possible in a simple manner to provide a hardened running surface for the support rollers, namely by appropriate heat treatment of the running ring or by a suitable choice of material. It is advisable to equip the support shafts with a conical mounting or roller bushing, which offers the race a better fit compared to a cylindrical mounting sleeve or bushing and also keeps the games less.
Wenn die Laufflächen vorteilhaft abgeschirmt sind, beispielsweise durch eine Abdeckung des Stützrollenpaares, lassen sie sich von Sinter freihalten.If the running surfaces are advantageously shielded, for example by covering the pair of support rollers, they can be kept free of sinter.
Weitere Merkmale und Vorteile der Erfindung ergeben sich aus den Patentansprüchen und der nachfolgenden Beschreibung, in der ein Ausführungsbeispiel des Gegenstandes der Erfindung näher erläutert ist. Es zeigen:
- Fig. 1
- eine Richtmaschine, in Längsrichtung der Tragwellen geschnitten dargestellt; und
- Fig. 2
- eine Teilansicht der Richtmaschine nach Fig. 1, von rechts gesehen.
- Fig. 1
- a straightening machine, shown cut in the longitudinal direction of the support shafts; and
- Fig. 2
- a partial view of the straightening machine according to FIG. 1, seen from the right.
Die in Fig. 1 gezeigte Richtmaschine 1 nimmt in ihrem Gehäuse 2 oben vier und drei versetzt dazu untenliegende Tragwellen 3 bzw. 4 auf; ein- und auslaufseitig ist unten zudem jeweils noch eine weitere Tragwelle 5 (vgl. Fig. 2) angeordnet. Die oberen und unteren Tragwellen 3, 4 bzw. 5 sind in einem ersten Lager 7 an der Antriebsseite 6 sowie mit Abstand davon in einem zweiten Lager 8 im Gehäuse 2 gelagert, das im wesentlichen aus Seitenständern 9 und damit verschraubten Quertraversen 10 besteht. Sowohl die oberen als auch die unteren Tragwellen 3, 4 werden von Motoren 11 bzw. Hilfsmotoren 12 angetrieben, wobei der schwächere Hilfsmotor 12 jeweils den unteren Tragwellen 4 zugeordnet ist, um eine das Einführen des Richtgutes erleichternde, unterhalb der Arbeitsgeschwindigkeit liegende Schleppgeschwindigkeit zu ermöglichen.The straightening
Um die Durchbiegung der Tragwellen 3 bzw. 4 zu verringern sowie gleichzeitig deren Vorspannung und/oder eine Optimierung der Spaltweite zu ermöglichen, sind an der Bedienungsseite 13 der Richtmaschine 1 mit dem Gehäuse 2 verbundene Anstellspindeln 14 angeordnet. Diese lassen sich über einen von einem Motor 15 betätigten Schneckenantrieb 16, von dem in Fig. 1 das Schneckenrad 17 und in Fig. 2 die Schneckenwelle 18 zu erkennen sind, stufenlos gegen die freien Enden der Tragwellen anstellen, so daß die Tragwellen 3, 4 während des Richtbetriebes zweiseitig abgestützt sind, nämlich durch die anstellseitigen Lager 7, 8 und die bedienungsseitigen Anstellspindeln 14. Dabei läßt sich eine symmetrische Anordnung dieser Abstützpunkte erreichen, was eine mittige Zuführung der von den auf den Tragwellen 3, 4 angeordneten Richtrollen 19 zu richtenden Profile 20 ermöglicht; der Transport der Profile 20 auf dem Zuführrollgang wird damit verbessert.In order to reduce the deflection of the supporting
Wie sich näher aus Fig. 2 entnehmen läßt, sind die den Tragwellen 3, 4 zugewandten Kopfenden der Anstellspindeln 14 mit einem Joch 21 versehen, in dem zwei sich gegen Laufflächen 22 der Tragwellen 3, 4 anlegende Stützrollen 23 unter einem Winkel 24 von 60° zueinander gelagert sind. Die Lauffläche 22 wird von einem Laufring 25 zur Verfügung gestellt, der in einer konischen, auch die Richtrollen 19 tragenden Montagebuchse 26 angeordnet ist. Zum Aufziehen der Montagebuchse 26 auf die Tragwellen 3, 4 dient eine unterhalb einer Schutzhaube 27 angeordnete hydraulische Spannmutter.As can be seen in more detail from FIG. 2, the head ends of the adjusting
Der untere Teil des Rahmens bzw. Gehäuses 2 der Richtmaschine 1 nimmt zwei Verstellspindeln 28, 29 auf, die über Schneckenräder 30, 31 von einem Getriebemotor 32 angetrieben werden und höhenverstellbar sind, so daß die Richtebene zum einen beim Übergang auf Profile anderer Größenordnung und zum anderen an die Rollgänge der Walzstraße angepaßt werden kann.The lower part of the frame or
Die mittels der einen großen Hub zusammen mit einer hohen Lasttragfähigkeit ermöglichenden Schneckenantriebe 16 von oben und unten gegen die freien Enden der Tragwellen 3, 4 angestellten Spindeln 14 gewährleisten somit trotz einer fliegenden Lagerung eine während des Richtbetriebes zweiseitige, zudem zur Vorspannung und Optimierung der Spaltweite einzusetzende Abstützung der Tragwellen 3, 4, was insbesondere das Richten großer und schwerer Profile 20 erlaubt, da sich die Tragwellen 3, 4 nur geringstmöglich durchbiegen können. Das wird durch das Weiterleiten der Stützkraft über die beiden in einem Winkel von 60° zueinander in dem Joch 21 angeordneten Stützrollen 23 an das Gehäuse 2 begünstigt. Bei einem Wechsel des Richtprogramms lassen sich die Anstellspindeln 14 schnell ausreichend weit von den Laufflächen 22, d.h. den Tragwellen 3, 4 wegfahren, so daß an der Bedienungsseite 13 ein genügender Freiraum vorliegt, um den alten gegen einen neuen Satz Richtrollen 19 auszutauschen.The worm drives 16, which enable a large stroke together with a high load-bearing capacity, from above and below against the free ends of the supporting
