The manipulation gripper is formed from operatable pliers. The device for hardening profiled running rails (1), comprises a cooling means, a transverse displacement means (21) in an area of roller tables, a directing means and a manipulation gripper (3) for introducing the rail in the device, a positioning means (4), a basin and/or a trough with a cooling agent, and a cooling bed (6). The running rails have optional different cross-sectional forms and a length of larger than 50 m by cooling a part of the respective rail cross section over a total rail length in the cooling means. The manipulation gripper is formed from identically-shaped, aligned and movably operatable pliers, which have homogenously movable and/or adjustable gripping arms formed with centering parts for an axial alignment of the heads of the rails and with gripper parts for a transversely-aligned holding of rail foots, so that an accurate introduction of the rails is possible in the positioning means and a regulation of the rails is possible in the positioning means. The manipulation gripper is formed with more than two pliers, each of which is 10 m of the basin length. The manipulation gripper and associated bringing means are spatially movable with more than the largest rail height over the roller table and the gripping arms of the pliers are partially lowered between the rollers of the roller tables for receiving the rails in a vertical manner. The positioning means has horizontally aligned retaining components with units for the foot of hangingly introduced rails, which is definable on the units by detachable clamping elements and/or compressor rods distortion-secured in the direction of the rail. The rail is immovably kept by one unit and one detachable clamping element for the rail foot of a component of the positioning means. The remaining units and the clamping elements allow a displacement in the longitudinal direction of the rail. Two basins are horizontally arranged next to each other with positioning means on equal height in an axial-parallel manner. The part of the cooling agent in the basin usable for hardening the rails has a depth, which exceeds 10% the height of the largest rail profile. The basin has a cooling agent inlet on the bottom-side having 1.5 m of the basin length. A regular cooling agent flow is supplyable through the cooling agent inlet. A perforated and flow-throughable plate distanced above the cooling agent inlet is arranged in the basin and/or a nozzle plate assigned in the flow direction of the cooling agent is inserted with channels. A deriving means for the cooling agent is arranged in the basin and/or in supply lines and is openly-adjustable for temporarily emptying the basin. The basin, the units and clamping elements are simultaneously movable in the cooling agent vertically relative to each other in a controlled manner. A vertical holding position and a time period of the basin, the units and clamping elements are adjustable. The units and clamping elements are simultaneously adjustable horizontally transverse to the basin.

Description

Die Erfindung bezieht sich auf eine Einrichtung zum Härten von Schienen, insbesondere profilierten Fahrschienen, mit gegebenenfalls jeweils unterschiedlicher Querschnittsform und einer Länge von größer als 50m durch Abkühlen von zumindest einem Teil des jeweiligen Schienenquerschnittes über die gesamte Schienenlänge in einem Kühlmittel, bestehend aus Querverschiebemitteln im Bereich eines Rollganges, aus Richtmitteln und Manipulationsgreifer zum Verbringen der Schiene in der Einrichtung, mindestens einem Positioniermittel, mit jeweils einem Becken bzw. Trog mit Kühlmittel sowie einem Kühlbett.The invention relates to a device for hardening rails, in particular profiled rails, optionally with a different cross-sectional shape and a length of greater than 50m by cooling at least part of the respective rail cross-section over the entire rail length in a coolant, consisting of Querverschiebemitteln in the area a roller table, of directing means and manipulation gripper for moving the rail in the device, at least one positioning means, each with a basin or trough with coolant and a cooling bed.

Schienen aus Kohlenstoff enthaltenden, gegebenenfalls niedriglegierten Stählen, die nach dem Walzen auf ein Kühlbett verbracht und erkalten gelassen werden, weisen durchwegs ein perlitisches Gefüge auf, wobei der Werkstoff dementsprechende mechanische Eigenschaften hat. Um den Schienenverschleiß, insbesondere bei hohen Achslasten sowie gegebenenfalls hoher Geschwindigkeit der Züge und in engen Kurven zu verringern, kann gemäß Stand der Technik durch eine besondere Wärmebehandlung die Gefügestruktur derart eingestellt werden, dass zumindest der beanspruchte Schienenkopf eine hohe Härte, eine hohe Abriebfestigkeit und eine geringe Rissinitiation hat, d.h., dass die Schiene im Gleis verbesserte Gebrauchseigenschaften aufweist.Rails of carbon-containing, optionally low-alloy steels, which are placed on a cooling bed after rolling and allowed to cool, have a pearlitic structure throughout, the material having corresponding mechanical properties. In order to reduce the rail wear, especially at high axle loads and possibly high speed trains and tight curves, the microstructure can be adjusted in such a way that at least the claimed rail head high hardness, high abrasion resistance and a has low Rissinitiation, ie, that the rail in the track has improved performance characteristics.

Eine Einrichtung zum Härten von Schienen durch eine gezielte Ausbildung der Gefügestruktur bei der Abkühlung derselben kann für einen Durchlauf durch eine Sprühkühlvorrichtung oder für ein Tauchen in ein Kühlmittel ausgebildet sein.A device for hardening rails by a targeted formation of the microstructure during the cooling of the same can be designed for a passage through a spray cooling device or for a dip in a coolant.

Durchlauf-Sprühkühlanlagen für eine Schienenhärtung sind in der Regel zwar einfach aufgebaut, haben jedoch den Nachteil eines großen Platzbedarfes, benötigen eine aufwändige Technologie und können auch unerwünschte Güteschwankungen der Schienen in einem Produktionsablauf nicht effizient ausschließen. Weiters kann oft in einer Durchlauf-Sprüheinrichtung eine genaue Abstimmung der Kühlung auf wechselnde Querschnittsprofile wie Zungen-, Rillen-, Vignolschienen und dgl. nicht in erforderlichem Masse erfolgen, wobei auch gegebenenfalls ein Verzug bei der Abkühlung von Querschnittsbereichen im Durchlauf zu ungleichen Kühlmittelbeaufschlagungen und somit zu Härteschwankungen des Werkstoffes über die Schienenlänge führt.Continuous spray cooling systems for rail hardening are generally simple in construction, but have the disadvantage of a large footprint, require a complex technology and can not exclude unwanted Güteschwankungen the rails in a production process not efficient. Furthermore, in a continuous spraying device, precise matching of the cooling to changing cross-sectional profiles, such as tongue, groove, Vignole rails and the like, can not be carried out to the required extent, whereby optionally also a delay in the cooling of cross-sectional areas in the passage to unequal coolant loads and thus leads to hardness variations of the material over the rail length.

Es wurde schon vorgeschlagen, bei einer Sprühvergütung der Schiene diese unbewegt zu belassen oder nur geringfügig, bevorzugt um den jeweiligen Sprühmittelabstand, alternierend zu verschieben.It has already been proposed, in the case of spray coating of the rail, to leave it stationary or to shift it only slightly, preferably by the respective spray agent spacing, alternately.

Weiters ist bekannt, eine Vorrichtung zum thermischen Vergüten von Schienen und/oder von Teilen des Querschnitts von Schienen mit einem oder mehreren Tauchbecken für diese auszubilden.Furthermore, it is known to form a device for thermal annealing of rails and / or parts of the cross section of rails with one or more immersion tanks for this.

Bei sequentieller Herstellung von gehärteten Schienen mit hoher Walzleistung wurde gemäss AT 410 549 B schon vorgeschlagen, mindestens zwei Flüssigkeitskühleinrichtungen jeweils parallel zu einem Ausrichtmittel anzuordnen und Quertransportmittel mit Walzgutauflagen zwischen den Rollgangsrollen vorzusehen, um ein Verbringen einer Schiene vom Rollgang zu Manipulatoren der Kühleinrichtung und in der Folge von diesen in den Auflagebereich eines Kühlbettes zu bewerkstelligen. Derart kann eine Steigerung der Durchsatzmenge von Schienen durch die Vergüteanlage erreicht werden. Ein Auslaufen aus dem Walzgerüst, ein Ausrichten und ein Drehen der Schiene am Rollgang ist jedoch bei aktivem Ausrichtmittel nicht uneingeschränkt möglich.In sequential production of hardened rails with high rolling performance was according to AT 410 549 B already proposed to arrange at least two liquid cooling devices in each case parallel to an alignment and provide transverse transport means with Walzgutauflagen between the roller conveyor rollers to accomplish a movement of a rail from the roller table to manipulators of the cooling device and in consequence of this in the support area of a cooling bed. In this way, an increase in the throughput of rails through the annealing plant can be achieved. However, leakage from the rolling stand, alignment and rotation of the rail on the roller table is not fully possible with active alignment.

Hier will die Erfindung die Mängel beseitigen und setzt sich zum Ziel, eine Einrichtung der eingangs genannten Art zum Härten von Schienen, insbesondere von profilierten Fahrschienen, zu schaffen, mit welcher bei hohem Durchsatz mit großer Sicherheit qualitativ hochwertige Schienen wirtschaftlich herstellbar sind.Here, the invention seeks to remedy the deficiencies and sets itself the goal of creating a device of the type mentioned for the hardening of rails, especially profiled rails, with which high throughput with high reliability high quality rails can be produced economically.

Im Einzelnen soll eine Anlage entsprechend der Zielsetzung Manipulationsgreifer für ein ungehindert rasches Verbringen der aus den Walzen auslaufenden Schienen aufweisen, welcher eine axiale Ausrichtung derselben ermöglicht, sowie eine maßgenaue Einbringbarkeit in einem Positioniermittel und/oder ein Ablegen auf ein Übergabemittel und/oder auf ein Kühlbett bewerkstelligt Positioniermittel für ein verzugsfreies Spannen und/oder Abschreckmittel, welches mit einem Positioniermittel zusammenwirkend einsetzbar ist, wobei Steuerungsmittel, durch welche die Anlagenkomponenten aufeinander für ein zyklisches Tauchen des Kopfes und/oder anderer Teile des Querschnittes und/oder der gesamten Oberfläche der Schiene in Verlauf von deren Abkühlung abstimmbar sind, aufweisen.Specifically, a plant according to the objective of manipulation gripper for unhindered rapid movement of the expiring from the rollers rails, which allows axial alignment of the same, and a dimensionally correct applicability in a positioning and / or depositing on a transfer means and / or on a cooling bed accomplishes positioning means for distortion-free clamping and / or quenching, which is cooperatively employable with a positioning means, wherein control means by which the plant components on each other for a cyclic dipping of the head and / or other parts of the cross section and / or the entire surface of the rail in course are tunable by their cooling.

Das Ziel wird bei einer gattungsgemäßen Einrichtung erreicht, wenn der Manipulationsgreifer aus Zangen gebildet ist, die Greifarme aufweisen, die jeweils mit Zentrierteilen für ein axiales Ausrichten des Kopfes der Schiene und mit Greifteilen für ein querschnittsfluchtendes Halten des Schienenfußes ausgeformt sind und derart eine maßgenaue Einbringung der Schiene im Positioniermittel und eine Festlegung derselben in diesem ermöglicht ist.The goal is achieved in a generic device when the manipulation gripper is formed from pliers having gripping arms, each with Centering parts for an axial alignment of the head of the rail and with gripping parts for a cross-aligned holding the rail foot are formed and thus a dimensionally accurate insertion of the rail in the positioning and a determination of the same is made possible in this.

Die Vorteile, die mit einem erfindungsgemäßen Manipulationsgreifer erreicht werden, sind im Wesentlichen darin zu sehen, dass dessen fluchtende Zangen Greifarme mit Zentrierteilen und Greifteilen aufweisen, sodass die Schiene unmittelbar nach dem letzten Walzstich und deren Auslaufen am Rollgang in der Walzhitze, also im duktilen bzw. weitgehend plastischen Zustand des Werkstoffes beim Schließen der Zangenteile vorerst kopfseitig axial ausrichtbar ist, worauf ein querschnittsfluchtendes Halten des Schienenfußes erfolgt und dabei Schienen nach axialem Drehen immer gleicher Art in ein Positioniermittel eingebracht oder auf ein Kühlbett aufgelegt werden können. Diese Art der Schieneneinbringung in ein Positioniermittel mit horizontal ausgerichtetem, fluchtendem Schienenfuß hängend hat den weiteren Vorteil, dass in diesem die Lage des Schienenfußes immer gleichartig vorliegt und diese gleichbleibende Lage auch bei unsymmetrischen Querschnittsprofilen gesichert werden kann.The advantages that are achieved with a manipulation gripper according to the invention are essentially to be seen in that its aligned pliers have gripping arms with centering parts and gripping parts, so that the rail immediately after the last rolling pass and their expiry on the roller table in the rolling heat, ie in the ductile or ., largely plastic state of the material when closing the pliers parts at first head side axially aligned, where a cross-aligned alignment of the rail takes place while rails after axial rotation always introduced the same kind in a positioning or can be placed on a cooling bed. This type of rail insertion into a positioning with horizontally aligned, aligned rail foot hanging has the further advantage that in this the position of the rail foot is always the same and this constant position can be secured even with asymmetrical cross-sectional profiles.

Die Zangen sind dabei um eine gemeinsame Axe zumindest mit einem Winkelbetrag gleichzeitig gleichsinnig drehbar ausgeführt, um Schienen aus unterschiedlichen Rollgang-Positionen, z.B. aus einer Liegeposition kopfseitig ausrichten, querschnittsfluchtend halten und durch axiales Drehen maßgenau in ein Positioniermittel einbringen zu können.The pliers are at the same time rotatable in the same direction about a common axis, at least with an angular amount, in order to move rails from different roller table positions, e.g. align from a lying position on the head side, keep it in line with the cross section and be able to accurately insert it into a positioning device by axial rotation.

Im Zuge des Austrages der Schiene aus dem Positioniermittel kann durch eine Drehung der Zangen die Schiene mit Vorteil in einer gewünschten Querschnitts- Lage auf ein Übergabemittel und/oder auf einem Kühlbett abgelegt werden.In the course of the discharge of the rail from the positioning means can be stored by rotation of the pliers, the rail with advantage in a desired cross-sectional position on a transfer agent and / or on a cooling bed.

Mit vorteilhaft hoher Präzision kann ein Verbringen von ausgerichteten Schienen in kurzer Zeit erfolgen, wenn der Manipulationsgreifer mit mehr als zwei Zangen je 10m Beckenlänge gebildet ist.With advantageously high precision, it is possible to dispose of aligned rails in a short time if the manipulation gripper is formed with more than two pliers per 10 m basin length.

Sowohl funktionstechnisch als auch im Hinblick auf das Ausricht- und Greifverhalten ist es günstig, wenn die Zangen mit jeweils einem gleichartig bewegbaren bzw. anstellbaren Greifarm gebildet sind.Both functionally and in terms of the alignment and gripping behavior, it is advantageous if the pliers are each formed with a similarly movable or engageable gripping arm.

Wenn in vorteilhafter Weise der Manipulationsgreifer und die zugehörigen Verbringungsmittel beabstandet mit mehr als der größten Schienenhöhe über dem Rollgang querbewegbar und nur die Greifarme der Zangen teilweise zwischen die Rollen des Rollganges zum Aufnehmen der Schiene vertikal absenkbar sind, bleibt eine Beaufschlagung des Rollgangendbereiches mit aus den Walzen auslaufenden Schienen ungestört bezüglich eines gleichzeitigen Verbringens von Schienen in der Härteeinrichtung, was eine hohe Flexibilität und Leistung derselben bzw. einen hohen Durchsatz sicherstellt.If, advantageously, the manipulation gripper and the associated transfer means can be moved transversely with more than the greatest rail height over the roller table and only the gripping arms of the pliers can be lowered vertically between the rollers of the roller table for receiving the rail, loading of the roller table end area from the rollers remains leaking rails undisturbed with respect to a simultaneous placement of rails in the hardening device, which ensures high flexibility and performance of the same or a high throughput.

Das Ziel wird bei einer Einrichtung der eingangs genannten Art zum Härten von Schienen erfindungsgemäß weiters dadurch erreicht, dass das Positioniermittel horizontal fluchtend eine Vielzahl von Haltekomponenten mit Anlagen für den Fuß einer hängend eingebrachten Schiene aufweist, welcher Schienenfuß jeweils auf den Anlagen durch lösbare Spannelemente bzw. Niederhalter verzugsgesichert in Axrichtung der Schiene horizontal festlegbar ist.The object is inventively further achieved in a device of the type mentioned above for the hardening of rails, that the positioning horizontally aligned a plurality of holding components with facilities for the foot of a hanging introduced rail, which rail foot respectively on the plants by releasable clamping elements or Hold-down delay-proof in the axial direction of the rail can be fixed horizontally.

Die mit dem erfindungsgemäßen Positioniermittel erreichten Vorteile sind im Wesentlichen darin zu sehen, dass dieses aus mit großer Genauigkeit horizontal fluchtenden Haltekomponenten mit jeweils zwei Anlagen und zwei Niederhalter gebildet sind. Derart kann eine Schiene aus der Walzhitze mit austenitischem Gefüge, die von einem Manipulationsgreifer axial ausgerichtet in einer bestimmten gewünschten Lage in die Haltekomponenten mit jeweils zwei Anlagen für den Fuß der Schiene eingelegt wird, durch jeweils zwei Spannelemente verschiebungs- und verwindungssicher festgelegt werden, welche Festlegung auch bei einem Einwirken großer Kräfte, z.B. in einer Abkühlphase des Schienenkopfes, mit hoher Genauigkeit erhalten bleibt. Die Haltekomponenten und die Niederhalter bzw. Spannelemente für den Schienenfuß sind in Längserstreckung des Positioniermittels jeweils gleicherarts vorgesehen, sodass mit Vorteil keinerlei Biegemomente bei der Festlegung der Schiene entstehen.The advantages achieved with the positioning means according to the invention are essentially to be seen in the fact that they are formed from holding components which are aligned horizontally with great accuracy, each having two installations and two hold-downs. Such a rail from the rolling heat with austenitic structure, which is inserted axially aligned by a manipulation gripper in a certain desired position in the holding components, each with two systems for the foot of the rail, are determined by two clamping elements each shift and warping, which determination even with an action of large forces, eg in a cooling phase of the rail head, with high accuracy is maintained. The holding components and the hold-down or clamping elements for the rail foot are provided in the longitudinal extent of the positioning respectively selbarts so that advantageously no bending moments arise in the determination of the rail.

Es hat sich als günstig erwiesen, wenn die Schiene beidseitig durch eine Anlage und ein lösbares Spannelement für den Schienenfuß einer Komponente des Positioniermittels unbewegbar gehalten ist und die übrigen Anlagen und Elemente der jeweiligen Komponenten eine Verschiebung in Schienenlängsrichtung zulassen. Dadurch kann auch während der Abkühlung bzw. Wärmebehandlung die Schiene in einer gewünschten Querschnitts- Position stabilisiert sein, wobei die durch die Werkstoffkontraktion gegebene Verkürzung durch eine Verschiebung frei von Oberflächenbeschädigungen erfolgt.It has proven to be advantageous if the rail is held immovably on both sides by a system and a releasable clamping element for the rail of a component of the positioning and the other facilities and elements of the respective components allow a shift in the rail longitudinal direction. As a result, even during the cooling or heat treatment, the rail can be stabilized in a desired cross-sectional position, wherein the shortening given by the material contraction takes place by a displacement free of surface damage.

Erreicht wird ein Ziel bei einer Einrichtung zum Härten von Schienen gemäß Oberbegriff des Hauptanspruchs auch dadurch, dass mindestens zwei Becken mit Positioniermitteln axparallel nebeneinander auf gleicher Höhe horizontal angeordnet sind und der für eine Schienenhärtung nutzbare Teil des Kühlmittels im Becken eine Tiefe aufweist, welche die Höhe des größten Schienenprofiles um mindestens 10% übersteigt.A goal is achieved in a device for hardening of rails according to the preamble of the main claim also in that at least two basins with positioning axparallel side by side at the same height are arranged horizontally and usable for a rail hardening part of the coolant in the basin has a depth which the height of the largest rail profile exceeds by at least 10%.

Die Vorteile dieses Merkmales der Erfindung sind hauptsächlich begründet durch eine mittels zwei Becken, die axparallel angeordnet sind, erreichte hohe Leistung und insbesondere Flexibilität der Härteeinrichtung und durch deren mittels steuerbaren Positioniermittel universelle Einsatzmöglichkeit gegebenenfalls für ein sequentielles, vollumfängliches Kühlen und/oder ein Kühlen von Teilen des Querschnitts beispielsweise ausschließlich des Kopfes oder der Lauffläche einer Schiene im Kühlmedium. Es ist mit der Einrichtung nach der Erfindung auch möglich, eine Vielzahl von Tauchparametern für die Schienen im Kühlmittel bei deren Härtung anzuwenden und somit eine gewünschte Gefügeverteilung über den Schienenquerschnitt zu erreichen.The advantages of this feature of the invention are mainly due to a high performance achieved by means of two basins, which are arranged axparallel, and in particular flexibility of the hardening device and by their universal use possible by means of controllable positioning means, optionally for a sequential, full cooling and / or cooling of parts the cross section, for example, only the head or the running surface of a rail in the cooling medium. It is also possible with the device according to the invention to apply a plurality of immersion parameters for the rails in the coolant during their curing and thus to achieve a desired microstructure distribution over the rail cross-section.

Nach einer bevorzugten Ausführungsform der Erfindung weist das Becken bodenseitig zumindest einen Kühlmitteleinlass je 1.5m Beckenlänge auf, durch welchen jeweils ein geregelter Kühlmittelstrom zuführbar ist, wobei vorzugsweise im Becken oberhalb der Kühlmitteleinlässe zu diesem abgedichtet distanziert zumindestens eine gelochte bzw. durchströmbare Platte angeordnet und/oder in Fließrichtung des Kühlmittels nachgeordnet eine Platte mit Düsen oder mit Kanälen eingesetzt ist (sind).According to a preferred embodiment of the invention, the basin on the bottom side at least one coolant inlet per 1.5m basin length, through which a regulated flow of coolant can be fed, preferably in the tank above the coolant inlet to this sealed spaced at least one perforated or durchströmbare plate arranged and / or in the flow direction of the coolant downstream of a plate with nozzles or with channels is (are) used.

Durch diese erfindungsgemäßen Maßnahmen kann die örtliche Kühlintensität des Kühlmittels für die Querschnittsoberflächenbereiche über die Schienenlängserstreckung gleichgehalten und in der Folge gewünscht hohe gleichbleibende Güte in der Herstellung von gehärteten Schienen erreicht werden.By means of these measures according to the invention, the local cooling intensity of the coolant for the cross-sectional surface areas can be kept the same over the longitudinal rail extension and consequently high uniform quality in the production of hardened rails can be achieved.

Wenn, nach einer Ausführungsform der Erfindung im Becken und/oder in den Zuleitungen Ableitungsmittel für das Kühlmittel angeordnet sind, die zur kurzzeitigen Entleerung des Beckens offenstellbar sind, kann z.B. bei einem Störungsfall in kürzest möglicher Zeit das Kühlmittel aus dem Becken ausgetragen werden, wodurch die Schienenhärtung unterbrochen ist. Diese Härtungsunterbrechung erbringt einen Schutz der Einrichtung und ein leichteres Ausbringen einer bei Anlagenstörung im Becken gehaltenen Schiene.If, according to an embodiment of the invention in the basin and / or in the supply lines discharge means for the coolant are arranged, which are open for short-term emptying of the basin, for example, in case of failure in the shortest possible time, the coolant can be discharged from the basin, causing the Rail hardening is interrupted. This cessation of interruption provides protection of the device and makes it easier to deploy a rail held in the pool during system failure.

Das gesetzte Ziel der Erfindung, eine neue Einrichtung zum Härten von Schienen mit unterschiedlich effektiven örtlichen Kühlintensitäten über deren Querschnitt zu schaffen, wird auch dadurch erreicht, dass das Becken und die Anlagen und die lösbaren Spannmittel für den Fuß der hängenden Schiene aller Komponenten des Positioniermittels zur Einbringung der Schiene in das Kühlmittel gleichzeitig vertikal relativ zueinander gesteuert bewegbar und eine jeweilige vertikale Halteposition und Zeitdauer in dieser einstellbar sind.The stated object of the invention to provide a new device for hardening rails with different effective local cooling intensities over the cross section is also achieved by the fact that the basin and the installations and the releasable clamping means for the foot of the hanging rail of all components of the positioning means Insertion of the rail in the coolant simultaneously vertically controlled relative to each other movable and a respective vertical holding position and time are adjustable in this.

Mit Vorteil sind derart gewünschte Gefügeausbildungen und auch Gefügebereiche mit unterschiedlicher Mikrostruktur über den Querschnitt von Schienen erreichbar, wodurch derartige Schienen mit einem für besondere Beanspruchungen günstig ausgebildeten Eigenschaftsprofil herstellbar sind.Advantageously, such desired structural formations and also structural regions with different microstructures can be achieved over the cross-section of rails, whereby such rails can be produced with a property profile designed to be favorable for particular stresses.

Um bei Schienen gegebenenfalls mit verschiedenen Querschnittsprofilen die Kopfhärte und die Verteilung der mechanischen Materialeigenschaften über den Querschnitt optimieren zu können, kann vorgesehen sein, dass die Anlage und die Spannmittel für den Fuß der hängenden Schiene aller Komponenten des Positioniermittels gleichzeitig horizontal quer zum Becken einstellbar sind.In order to be able to optimize the head hardness and the distribution of the mechanical material properties over the cross section in rails, where appropriate with different cross-sectional profiles, it can be provided that the system and the clamping means for the foot of the hanging rail of all components of the positioning means are simultaneously horizontally adjustable transversely to the pelvis.
