Description

Vorrichtung und Verfahren zum Walzprofilieren von Profilen mit veränderlichem Apparatus and method for roll forming profiles with variable
Querschnittcross-section
Die Erfindung betrifft eine Vorrichtung und ein Verfahren gemäß den Oberbegriffen der unabhängigen Patentansprüche.The invention relates to a device and a method according to the preambles of the independent claims.
Eine derartige Vorrichtung, mit der Profile mit veränderlichen Querschnitten erzeugt werden können, indem Walzenpaare mit einer Translations- und einer Rotationsbewegung verstellt werden, ist aus der DE 100 11 755 Al bekannt. Eine ähnliche Vorrichtung mit einer zusätzlichen Walze und einem Stützelement für einen am Halbzeug ausgebildeten Flansch ist aus der DE 10 2004 040 257 Al bekannt.Such a device, with the profiles with variable cross-sections can be generated by pairs of rollers are moved with a translational and a rotational movement, is known from DE 100 11 755 Al. A similar device with an additional roller and a support element for a flange formed on the semi-finished product is known from DE 10 2004 040 257 Al.
Bei der aus der DE 100 11 755 Al bekannten Vorrichtung bzw. dem damit durchgeführten Verfahren werden die Translationsbewegung und die Drehbewegung weitgehend unabhängig voneinander erzeugt. Nachteilig hierbei ist, dass der für die Translationsbewegung verantwortliche Linearaktuator die gesamte Verschubarbeit alleine leisten muss, wenn eine reine Translationsbewegung erzeugt wird, und dass der für die Rotationsbewegung verantwortliche Linearaktuator die gesamte Verdreharbeit alleine leisten muss, wenn eine reine Rotationsbewegung erzeugt wird. Daher müssen die beiden Linearaktuatoren zusammengenommen sowohl von der Leistung als auch von den Abmessungen her größer ausgelegt werden als es zur Erzielung der im Betrieb tatsächlich erforderlichen Gesamtleistung nötig wäre.In the device known from DE 100 11 755 A1 or the method performed therewith, the translational movement and the rotational movement are generated largely independently of one another. The disadvantage here is that the linear actuator responsible for the translational movement must perform the entire Verschubarbeit alone when a pure translational motion is generated, and that the responsible for the rotational movement of the linear actuator must perform the entire twisting work alone when a pure rotational motion is generated. Therefore, the two linear actuators taken together have to be designed to be larger in size both in terms of performance and dimensions than in order to be able to operate them actually required overall performance would be necessary.
Der Erfindung liegt die Aufgabe zugrunde, das Walzprofilieren von Kalt- oder Warmprofilen mit veränderlichem Querschnitt über Walzen und Matrizen mittels leistungsärmerer und platzsparender Antriebe zu ermöglichen.The invention has for its object to enable the rolling profiling of cold or hot profiles with variable cross-section of rolls and dies by means of power-poorer and space-saving drives.
Diese Aufgabe wird bei einer gattungsgemäßen Vorrichtung und dem entsprechenden Verfahren durch die kennzeichnenden Merkmale der unabhängigen Patentansprüche gelöst.This object is achieved in a generic device and the corresponding method by the characterizing features of the independent claims.
Im Unterschied zu der aus der DE 100 11 755 Al bekannten Vorrichtung, bei der sich der für die Translationsbewegung verantwortliche Linearaktuator entlang der Verbindungslinie zwischen der maschinenfesten Abstützung des Linearaktuators und der Drehachse des Walzengerüsts erstreckt, ist bei der Erfindung jeder der zwei mindestens vorhandenen Linearaktuatoren an einer von der Drehachse des Walzengerüsts beabstandeten Stelle an dem Walzengerüst angelenkt. Anders ausgedrückt, sowohl eine reine Translationsbewegung als auch eine reine Rotationsbewegung des Walzengerüsts wird durch die zwei mindestens vorhandenen Linearaktuatoren gemeinsam erzeugt. Dadurch werden Verschubarbeiten und Verdreharbeiten auf die beiden Linearaktuatoren verteilt, und zwar besonders gleichmäßig bei den häufig benötigten reinen Translationsund Rotationsbewegungen des Walzengerüsts. Daher können die Linearaktuatoren wesentlich leistungsschwächer und kompakter sein als diejenigen der bekannten Biegevorrichtungen.In contrast to the device known from DE 100 11 755 A1, in which the linear actuator responsible for the translatory movement extends along the connecting line between the machine-fixed support of the linear actuator and the axis of rotation of the rolling stand, in the invention, each of the two at least existing linear actuators one of the axis of rotation of the roll stand spaced location hinged to the mill stand. In other words, both a pure translational movement and a pure rotational movement of the rolling stand is generated jointly by the two at least existing linear actuators. As a result, shifting work and twisting work are distributed to the two linear actuators, and particularly uniformly in the case of the often required pure translational and rotational movements of the rolling mill stand. Therefore, the linear actuators can be much less powerful and more compact than those of the known bending devices.

Fig. 3 ein weiteres Ausführungsbeispiel für ein Verstellgerüst.Fig. 3 shows a further embodiment of an adjustment frame.
Das in Fig. 1 perspektivisch gezeigte Verstellgerüst hat eine längliche rechteckige Grundplatte 2 mit zwei Linearführungsschienen 4, die sich entlang der Längskanten der Grundplatte 2 erstrecken. An den beiden Linearführungsschienen 4 ist ein Schlitten 6 verschiebbar gelagert, d.h. der Schlitten 6 ist in der X- Richtung des eingezeichneten kartesischen Koordinatensystems auf der Grundplatte 2 verschiebbar gelagert. Auf dem Schlitten 6 ist mittig eine in diesem Ausführungsbeispiel kreisrunde, grundsätzlich aber beliebig geformte Basisplatte 8 eines nicht gezeigten Walzengerüsts drehbar gelagert, d.h. die Basisplatte 8 ist in der Y-Richtung drehbar gelagert.The adjusting frame shown in perspective in FIG. 1 has an elongate rectangular base plate 2 with two linear guide rails 4, which extend along the longitudinal edges of the base plate 2. On the two linear guide rails 4, a carriage 6 is slidably mounted, i. the carriage 6 is slidably mounted on the base plate 2 in the X direction of the drawn Cartesian coordinate system. On the carriage 6 in the middle of a circular in this embodiment, basically arbitrarily shaped base plate 8 of a rolling stand, not shown rotatably mounted, i. the base plate 8 is rotatably supported in the Y direction.
Das an der Basisplatte 8 befestigte Walzengerüst ist von einer Art wie in den schon genannten Druckschriften DE 100 11 755 Al und DE 10 2004 040 257 Al beschrieben und enthält Profiliereinrichtungen wie z.B. Walzen und/oder Matrizen. Ein zu bearbeitendes Profil bzw. Halbzeug wird in der Z-Richtung in Fig. 1 zugeführt und vorgeschoben und wird durch Verstellen des Walzengerüsts in der X-Richtung und um die Y-Achse mit veränderlichem Querschnitt versehen, wobei das Profil kalt oder warm verformt werden kann.The mill stand attached to the base plate 8 is of a type as described in the already mentioned publications DE 100 11 755 A1 and DE 10 2004 040 257 A1 and contains profiling devices such as e.g. Rolls and / or dies. A profile or semi-finished product to be processed is fed and advanced in the Z-direction in Fig. 1 and is provided by adjusting the roll stand in the X-direction and around the Y-axis of variable cross-section, wherein the profile are cold or hot deformed can.
Parallel zu jeder Linearführungsschiene 4 und oberhalb des Schlittens 6 erstreckt sich jeweils eine Gewindespindel 10, deren Enden in auf der Grundplatte 2 befestigten Lagerböcken gelagert sind. Ein Ende jeder Gewindespindel 10 ist axial mit einer Einheit 12 aus einem Elektromotor und einem Getriebe gekoppelt, die an einem der Lagerböcke befestigt ist und nachfolgend kurz Antriebsmotor genannt wird. Die beiden Antriebsmotoren 12 ragen in X-Richtung über die Grundplatte 2 hinaus, und sie sind nebeneinander achsparallel zur X-Richtung angeordnet.Parallel to each linear guide rail 4 and above the carriage 6 each extending a threaded spindle 10, whose ends are mounted in mounted on the base plate 2 bearing blocks. One end of each threaded spindle 10 is axial is coupled to a unit 12 of an electric motor and a transmission which is fixed to one of the bearing blocks and is hereinafter referred to as the drive motor. The two drive motors 12 protrude beyond the base plate 2 in the X direction, and they are arranged side by side parallel to the axis of the X direction.
Auf jeder der beiden Linearführungsschienen 4 ist außer der Grundplatte 2 auch ein Hilfsschlitten 14 verschiebbar gelagert, wobei jede Gewindespindel 10 mit einer am zugehörigen Schlitten 14 befestigten Mutter oder einem darin ausgebildeten Innengewinde in Eingriff steht. Mit jedem der beiden Hilfsschlitten 14 ist eine Schubstange 16 gelenkig (d.h. über ein Dreh- oder Kugelgelenk) gekoppelt, welche Schubstange 16 ungefähr parallel zu der benachbarten Linearführungsschiene 4 bis zu einer Stelle an der Basisplatte 8 verläuft, wo sie gelenkig (d.h. über ein Dreh- oder Kugelgelenk) mit der Basisplatte 8 gekoppelt ist. Die mit kleinen Kreisen markierten Stellen an der Basisplatte 8, an denen die Schubstangen 16 mit der Basisplatte 8 gekoppelt sind, liegen in Bezug auf die in Y-Richtung verlaufende Achse (Y-Achse) der Basisplatte 8 bzw. des Walzengerüsts radial und äquidistant einander gegenüber.On each of the two linear guide rails 4 except the base plate 2 and an auxiliary carriage 14 is slidably mounted, each threaded spindle 10 is in engagement with a nut 14 attached to the associated carriage or an internal thread formed therein. With each of the two auxiliary carriages 14, a push rod 16 is articulated (ie via a rotary or ball joint), which push rod 16 approximately parallel to the adjacent linear guide rail 4 to a point on the base plate 8, where they articulated (ie via a rotation - Or ball joint) is coupled to the base plate 8. The small-circle marks on the base plate 8 where the push rods 16 are coupled to the base plate 8 are radially and equidistant from each other with respect to the Y-direction axis (Y-axis) of the base plate 8 and the roll stand, respectively across from.
Werden die Gewindespindeln 10 mittels der Antriebsmotoren 12 mit gleicher Geschwindigkeit und in entgegengesetzten Drehrichtungen angetrieben, wird die Basisplatte 8 bzw. das Walzengerüst mittels der Schubstangen 16 um die Y-Achse gedreht. Werden die Gewindespindeln 10 mittels der Antriebsmotoren 12 mit gleicher Geschwindigkeit und in gleichen Drehrichtungen angetrieben, wird die Basisplatte 8 bzw. das Walzengerüst mittels der Schubstangen 16 in der X- Richtung verschoben. Durch geeignete Wahl der Drehrichtungen und Drehgeschwindigkeiten der Antriebsmotoren 12 kann die Basisplatte 8 bzw. das Walzengerüst einer beliebigen Kombination von Rotationsbewegungen um die Y- Achse und Translationsbewegungen in der X-Richtung unterzogen werden, d.h. in zwei Freiheitsgraden bewegt werden, um ein gerade bearbeitetes Profilhalbzeug mit veränderlichem Querschnitt zu versehen. Die erheblichen Kräfte, die bei der Umformung auftreten, verteilen sich auf beide Antriebe. Sowohl Drehmomente als auch Schubkräfte, die auszuüben sind, werden gleichmäßig auf beide Antriebsmotoren 12 verteilt, so dass diese schwächer dimensioniert werden können als bei konventionellen Verstellgerüsten. Auch die Kraftübertragungsglieder von den Antriebsmotoren 12 zur Basisplatte 8 können schwächer dimensioniert werden. Die Antriebsmotoren 12 sind so angeordnet, dass sie parallel sind und nicht mitbewegt werden. Dies ermöglicht einen kurzen Abstand zwischen Walzengerüsten, die jeweils an einem Verstellgerüst wie in Fig. 1 gezeigt angebracht sind.If the threaded spindles 10 are driven by the drive motors 12 at the same speed and in opposite directions of rotation, the base plate 8 or the roll stand is rotated about the Y-axis by means of the push rods 16. If the threaded spindles 10 are driven by the drive motors 12 at the same speed and in the same directions of rotation, the base plate 8 or the roll stand is displaced by means of the push rods 16 in the X direction. By suitable choice of the directions of rotation and rotational speeds of the drive motors 12, the base plate 8 or the roll stand can be subjected to any combination of rotational movements about the Y-axis and translational movements in the X-direction, ie moved in two degrees of freedom, around a semi-finished profile product being processed to be provided with variable cross-section. The considerable forces that occur during forming are distributed over both drives. Both torques and shear forces that are to be exerted are evenly distributed to both drive motors 12, so that they can be dimensioned smaller than conventional adjustment stands. Also, the power transmission members of the drive motors 12 to the base plate 8 can be dimensioned smaller. The drive motors 12 are arranged so that they are parallel and not moved. This allows a short distance between roll stands, which are each mounted on a Verstellgerüst as shown in Fig. 1.
Fig. 2 zeigt perspektivische Prinzip skizzen von Verstellgerüsten in einem Fig. 1 entsprechenden kartesischen Koordinatensystem. Gelenkige Verbindungen (z.B. mittels Dreh- oder Kugelgelenken) sind hier als schwarze Punkte eingezeichnet.Fig. 2 shows perspective principle sketches of Verstellgerüsten in a Fig. 1 corresponding Cartesian coordinate system. Articulated joints (e.g., by means of rotary or ball joints) are shown here as black dots.
Fig. 2a zeigt ein Verstellgerüst ähnlich wie in Fig. 1 , wobei die in Fig. 1 aus den Elementen 10, 12, 14 und 16 bestehenden Linearaktuatoren in Fig. 2 schematisch als Linearaktuatoren 20, 22 dargestellt sind, die jeweils eine hin und her bewegliche Schubstange 20a, 22a aufweisen, welche über weitere Schubstangen an der Basisplatte 24 eines nicht gezeigten Walzengerüsts angreifen.Fig. 2a shows a Verstellgerüst similar to that in Fig. 1, wherein the existing in Fig. 1 of the elements 10, 12, 14 and 16 linear actuators in Fig. 2 are shown as linear actuators 20, 22, each one back and forth have movable push rod 20a, 22a, which attack via further push rods on the base plate 24 of a rolling stand, not shown.
Fig. 2b zeigt das Verstellgerüst von Fig. 2a, erweitert um einen dritten, zwischen den Linearaktuatoren 20, 22 und parallel dazu angeordneten Linearaktuator 26, der über eine weitere Schubstange 28, die in einer Mittelstellung des Verstellgerüsts ungefähr in einem Winkel von 45 Grad zur Y-Richtung und zur Y- Richtung schräg steht, an einem dritten Angriffspunkt an der Basisplatte 24 angreift, welcher von den Angriffspunkten der Linearaktuatoren 20, 22 beabstandet ist und nicht in einer Linie mit ihnen liegt.Fig. 2b shows the Verstellgerüst of Fig. 2a, extended by a third, between the linear actuators 20, 22 and arranged parallel to linear actuator 26, which is connected via a further push rod 28 in a middle position of the Verstellgerüsts approximately at an angle of 45 degrees Y-direction and the Y-direction obliquely, at a third point on the base plate 24 engages, which is spaced from the points of application of the linear actuators 20, 22 and is not in line with them.
Bei dem Verstellgerüst von Fig. 2b ist die Basisplatte 24 zusätzlich in Y-Richtung verschiebbar gelagert, so dass sie mit Hilfe des dritten Linearaktuators 26 in einem weiteren Freiheitsgrad translatiert werden kann.In the adjusting frame of FIG. 2b, the base plate 24 is additionally in the Y direction slidably mounted so that it can be translated by means of the third linear actuator 26 in a further degree of freedom.
Alternativ kann bei dem Verstellgerüst von Fig. 2b die Basisplatte 24 um die Z- Achse schwenkbar gelagert sein, statt in Y-Richtung verschiebbar zu sein, so dass der zusätzlich erzielte Freiheitsgrad ein Freiheitsgrad der Rotation statt der Translation ist.Alternatively, in the adjusting frame of Fig. 2b, the base plate 24 may be pivotally mounted about the Z axis, instead of being displaceable in the Y direction, so that the additionally achieved degree of freedom is a degree of freedom of rotation instead of translation.
Trotz dieser zusätzlichen Funktionalität nimmt dieses Verstellgerüst von Fig. 2b praktisch nicht mehr Raum ein als das Verstellgerüst von Fig. 2a, und die auftretenden Kräfte werden auf noch einen Antrieb verteilt.Despite this additional functionality of this adjusting frame of Fig. 2b takes practically no more space than the adjusting frame of Fig. 2a, and the forces are distributed to yet another drive.
Fig. 2c zeigt das Verstellgerüst von Fig. 2a, erweitert um einen dritten und einen vierten Linearaktuator 30, 32 mit je einer weiteren Schubstange, die senkrecht zu den Linearaktuatoren 20, 22 angeordnet sind und an zwei Angriffspunkten der Basisplatte 24 angreifen, die von den Angriffspunkten der Linearaktuatoren 20, 22 beabstandet sind und in Bezug auf die in X-Richtung verlaufende Achse (X- Achse) der Basisplatte 24 radial und äquidistant einander gegenüberliegen.Fig. 2c shows the Verstellgerüst of Fig. 2a, extended by a third and a fourth linear actuator 30, 32, each with a further push rod, which are perpendicular to the linear actuators 20, 22 and engage two points of attack of the base plate 24, which of the Engagement points of the linear actuators 20, 22 are spaced and with respect to the extending in the X direction axis (X axis) of the base plate 24 radially and equidistant from each other.
Das Verstellgerüst von Fig. 2c kann mit den Linearaktuatoren 20, 22, 30 und 32 in vier Freiheitsgraden bewegt werden. Dazu muss die Basisplatte 24 mit vier Freiheitsgraden gelagert werden. Statt mit Dreh- und Gleitlagern wie in den vorangegangenen Ausführungsbeispielen erreicht man dies wesentlich einfacher mit zwei weiteren, fünften und sechsten Schubstangen 34, 36, die an einem Ende mit maschinenfesten Punkten 38 verbunden sind und am anderen Ende an irgendwelchen Punkten des Walzengerüsts angreifen, die nicht in der Ebene der Basisplatte 24 liegen, z.B. an den Enden einer axialen Stange durch die Basisplatte 24 hindurch, wie in Fig. 2c schematisch gezeigt.The adjusting frame of Fig. 2c can be moved with the linear actuators 20, 22, 30 and 32 in four degrees of freedom. For this purpose, the base plate 24 must be stored with four degrees of freedom. Instead of rotating and sliding bearings as in the previous embodiments to achieve this much easier with two other, fifth and sixth push rods 34, 36 which are connected at one end with machine-fixed points 38 and attack at the other end at any points of the roll stand, the not in the plane of the base plate 24 are, for example at the ends of an axial rod through the base plate 24, as shown schematically in Fig. 2c.
Werden diese fünften und sechsten Schubstangen 34 und 36 statt mit den maschinenfesten 38 Punkten mit einem fünften bzw. einem sechsten Linearaktuator 40, 42 verbunden, so kommt man zu dem Ausführungsbeispiel von Fig. 2d, in dem das Walzengerüst in sechs Freiheitsgraden, drei der Rotation und drei der Translation, beweglich ist.Are these fifth and sixth push rods 34 and 36 instead of the machine-fixed at 38 points connected to a fifth and a sixth linear actuator 40, 42, one arrives at the embodiment of Fig. 2d, in which the rolling mill in six degrees of freedom, three of rotation and three of translation, is movable.
Übrigens müssen die Linearaktuatoren und Schubstangen nicht parallel bzw. senkrecht zueinander angeordnet sein, wie in Fig. 2 gezeigt, sondern können mit gewissen Ausnahmen im Wesentlichen beliebige Lagen im Raum einnehmen. Auch die Angriffspunkte der Linearaktuatoren an der Basisplatte 24 bzw. dem Walzengerüst sind mit einigen Ausnahmen im Wesentlichen beliebig.Incidentally, the linear actuators and push rods need not be arranged parallel or perpendicular to each other, as shown in Fig. 2, but may, with certain exceptions substantially occupy any positions in space. The points of application of the linear actuators on the base plate 24 and the roll stand are essentially arbitrary with some exceptions.
Übrigens wird ein Positioniersystem wie in Fig. 2a Bipod genannt, ein Positioniersystem wie in Fig. 2c wird Tripod genannt, ein Positioniersystem wie in Fig. 2c wird Tetrapod genannt, und ein Positioniersystem wie in Fig. 2d wird Hexapod oder Hexaglide genannt, wie grundsätzlich bekannt. Außerdem gibt es sogenannte Pentapods, die man sich so vorstellen kann, dass einer der Linearaktuatoren in Fig. 2d durch einen maschinenfesten Punkt ersetzt ist, wobei ebenfalls Bewegungen in allen Raumrichtungen möglich sind.By the way, a positioning system as in Fig. 2a is called a bipod, a positioning system as in Fig. 2c is called a tripod, a positioning system as in Fig. 2c is called a tetrapod, and a positioning system as in Fig. 2d is called a hexapod or hexaglide, as basically known. In addition, there are so-called pentapods, which can be thought of as one of the linear actuators in Fig. 2d is replaced by a machine-fixed point, which also movements in all directions are possible.
Bei Anwendung von solchen Positioniersystemen auf ein Walzengerüst zum Walzprofilieren von Kalt- oder Warmprofilen mit veränderlichem Querschnitt über Walzen und Matrizen kommt der Umstand besonders zum Tragen, dass sich die im Betrieb wirkenden Kräfte auf alle Antriebe verteilen. Die auf ein Walzengerüst wirkenden bzw. auszuübenden Kräfte sind nämlich besonders hoch, und die Dimensionierungsersparnisse aufgrund der Kräfteaufteilung wirken sich hier besonders vorteilhaft aus, da sie es ermöglichen, Walzengerüste sehr nahe beieinander anzuordnen, so dass auch relativ schlanke Profile mit veränderlichem Querschnitt versehen werden können, welche wegen ausladender Verstellgerüste bisher nicht durch Walzprofilieren herstellbar waren. Fig. 3 zeigt ein weiteres Ausfuhrimgsbeispiel für ein Verstellgerüst, das dem in Fig. 1 gezeigten Verstellgerüst insoweit ähnlich ist, als es ebenfalls eine längliche rechteckige Grundplatte 2', zwei auf der Grundplatte 2' befestigte Linearführungsschienen 4', einen entlang der Linearführungsschienen 4' verschiebbaren Schlitten 6' und eine drehbar auf dem Schlitten 6' gelagerte Basisplatte 8' eines Walzengerüsts aufweist.When using such positioning on a roll stand for roll forming cold or hot profiles with variable cross-section of rollers and matrices, the fact is particularly important that distribute the forces acting in operation on all drives. In fact, the forces acting or to be exerted on a roll stand are particularly high, and the dimensioning savings due to the distribution of forces have a particularly advantageous effect, since they make it possible to arrange mill stands very close to one another, so that even relatively slim profiles with variable cross sections can be provided , which have not been produced by roll profiling because of cantilevered adjusting frames. FIG. 3 shows a further embodiment of an adjustment frame which is similar to the adjusting frame shown in FIG. 1 insofar as it also has an elongate rectangular base plate 2 ', two linear guide rails 4' fastened on the base plate 2 ', one along the linear guide rails 4'. slidable carriage 6 'and a rotatably mounted on the carriage 6' mounted base plate 8 'of a roll stand.
Anders als bei dem Ausführungsbeispiel von Fig. 1 werden die Linearantriebe nicht durch je eine Gewindespindel 10, einen Antriebsmotor 12, einen Hilfsschlitten 14 und eine Schubstange 16 gebildet, sondern jeweils durch ein Maschinenelement, das einen auf der Grundplatte 2' horizontal drehbar gelagerten Lagerbock 44, eine durch den Lagerbock 44 hindurchgehende Schubstange 46, die an einem Ende an der Basisplatte 8' angelenkt ist, und einen Antriebsmotor 48 umfasst.Unlike the embodiment of FIG. 1, the linear drives are not formed by a respective threaded spindle 10, a drive motor 12, an auxiliary slide 14 and a push rod 16, but each by a machine element, the one mounted on the base plate 2 'horizontally rotatable bearing block 44th a push rod 46 passing through the bearing block 44 hinged at one end to the base plate 8 'and including a drive motor 48.
Die Schubstange 46 kann eine Spindel sein, die durch eine Spindelmutter im Lagerbock 44 hindurchgeht und über ein Vorgelege vom Antriebsmotor 48 gedreht wird, wobei die Schubstange 46 in sich drehbar an einem Ende an der Basisplatte 8' angelenkt sein muss. Die Schubstange 46 kann auch eine Spindel sein, die vom Antriebsmotor 48 gedreht wird und durch eine an der Basisplatte 8' angelenkte Spindelmutter hindurchgeht. Bei derartigen Spindellösungen für die Schubstangen 46 muss natürlich das auftretende Drehmoment abgestützt bzw. durch den Motor eingeleitet werden. Alternativ kann die Schubstange 46 eine Stange sein, die auf irgendeine andere Weise vom Antriebsmotor 48 vor- und zurückgeschoben wird.The push rod 46 may be a spindle which passes through a spindle nut in the bearing block 44 and is rotated by a countershaft from the drive motor 48, wherein the push rod 46 has to be rotatably hinged at one end to the base plate 8 '. The push rod 46 may also be a spindle which is rotated by the drive motor 48 and passes through a spindle nut hinged to the base plate 8 '. In such spindle solutions for the push rods 46 of course, the torque occurring must be supported or initiated by the engine. Alternatively, the push rod 46 may be a rod that is pushed back and forth by the drive motor 48 in some other way.
In den Ausführungsbeispiel von Fig. 3 sind die Linearaktuatoren somit beidendig drehbar gelagerte Maschinenelemente, die auch in den Varianten und Weiterbildungen der Fig. 2 verwendet werden können, indem statt Drehlagern Kupplungen verwendet werden, die in mehreren Dimensionen gelenkig sind. In den Ausfiihrungsbeispiel von Fig. 3 erstrecken sich die beiden Schubstangen 46 nur in dem Sonderfall, dass sie gleich weit ausgefahren sind, genau parallel zueinander. In anderen Fällen nähern sie sich zur Basisplatte 8' hin einander an. Um der daraus resultierenden Drehmomentverminderung bei bestimmten Drehwinkeln der Basisplatte 8 entgegenzuwirken, könnte man die beiden Lagerböcke 44 von vornherein weiter voneinander entfernt oder näher beieinander anordnen als es in Fig. 3 gezeigt ist, je nachdem, welcheIn the exemplary embodiment of FIG. 3, the linear actuators are thus machine elements rotatably mounted at both ends, which can also be used in the variants and further developments of FIG. 2, by using couplings which are articulated in several dimensions instead of rotary bearings. In the exemplary embodiment of FIG. 3, the two push rods 46 extend exactly parallel to one another only in the special case that they are extended equidistant. In other cases, they approach each other toward the base plate 8 '. In order to counteract the resulting torque reduction at certain angles of rotation of the base plate 8, one could from the outset the two bearing blocks 44 further apart from each other or arrange closer to each other than it is shown in Fig. 3, whichever
Drehmomentcharakteristiken im Anwendungsfall am günstigsten sind. Auch bei den früher beschriebenen Ausführungsbeispielen ist es nicht notwendig, dass die Linearaktuatoren bzw. je zwei Linearaktuatoren oder irgendwelche Elemente der Linearaktuatoren genau parallel zueinander sind, wenngleich dies die Konstruktion und Steuerung vereinfacht.Torque characteristics are the most favorable in the application. Even in the embodiments described earlier, it is not necessary that the linear actuators or any two linear actuators or any elements of the linear actuators are exactly parallel to each other, although this simplifies the design and control.
Je nach Anwendungsfall kann man auch in Betracht ziehen, die Linearaktuatoren nicht an einander diametral gegenüberliegenden Stellen an der Basisplatte anzulenken, wie in den Ausführungsbeispielen gezeigt, sondern an Stellen, die in anderen Winkeln als 180° in Bezug auf die Drehachse der Basisplatte liegen und die möglicherweise auch unterschiedliche Abstände von der Drehachse der Basisplatte haben. Auch auf diese Weise kann man bestimmte gewünschte Drehmomentcharakteristiken erzielen.Depending on the application, it may also be considered not to direct the linear actuators at diametrically opposite locations on the base plate, as shown in the embodiments, but at locations which are at angles other than 180 ° with respect to the axis of rotation of the base plate and possibly also have different distances from the axis of rotation of the base plate. Also in this way one can achieve certain desired torque characteristics.
Die Linearaktuatoren müssen auch nicht orthogonal zu der Drehachse des Walzengerüsts verlaufen. In manchen Anwendungen kann auch eine mehr oder weniger schiefe Anordnung der Linearaktuatoren zu der Drehachse des Walzengerüsts günstig sein.Nor must the linear actuators be orthogonal to the axis of rotation of the mill stand. In some applications, a more or less oblique arrangement of the linear actuators to the axis of rotation of the roll stand can be beneficial.
Die Erfindung ist nicht auf die oben beschriebenen Ausführungsbeispiele beschränkt. So kann der Antrieb elektrisch, hydraulisch, pneumatisch und/oder mechanisch mittels Elektromotoren, Linearmotoren, Hydraulikzylindern, Hydraulikmotoren, Pneumatikmotoren oder Elektrozylindern (elektrischer Antrieb ohne nach außen wirksames Drehmoment) erfolgen. Zum Beispiel mechanische Antriebe können mit Gewindespindeln, Kugeltrieben, Zahnstangen, Schwenkantrieben, Umschlingungsgetrieben, Zylinder/Kolben und anderen Kraftübertragungselementen ausgeführt sein.The invention is not limited to the embodiments described above. Thus, the drive electrically, hydraulically, pneumatically and / or mechanically by means of electric motors, linear motors, hydraulic cylinders, Hydraulic motors, pneumatic motors or electric cylinders (electric drive without externally effective torque) take place. For example, mechanical drives can be designed with threaded spindles, ball screws, racks, quarter-turn actuators, belt drives, cylinders / pistons and other power transmission elements.
