Description

Die Erfindung betrifft eine Anlage zum Regenerieren bzw. erneutem Ausrichten von offenen Profilstählen, vorzugsweise Spundwandprofilen oder wasserdichten Pfählen, welche bei Ingenieur- und Industriebauten verwendet werden.The invention relates to a system for regenerating or realigning open section steels, preferably sheet piling sections or watertight piles, which are used in engineering and industrial buildings.

Aus der DE-C Nr. 914862 ist eine Durchlaufvorrichtung zum Härten, Vergüten und Biegen oder Richten von dünnwandigen Profilstählen bekannt. Bei dieser bekannten Vorrichtung werden Muffeln aus hitzebeständigem Werkstoff verwendet, die als Durchtrittsöffnung das Profil des Härteguts haben und dieses einbetten, wobei die Muffel entweder selbst beheizt werden kann oder aber in einem Durchlaufofen eingelegt ist. An diese Muffel schliesst sich ein Härteaggregat an, durch welches das zu härtende Gut hindurchläuft und in welchem die Profilstäbe gehärtet, vergütet, gerichtet oder gebogen werden, ohne dass sie die Form verlieren und ohne dass Restspannungen in dem Profil verbleiben. Diese Vorrichtung gewährleistet lediglich eine Wärmebehandlung von insbesondere dünnwandigen Profilstäben, welche gleichzeitig einen nicht näher bestimmten Richt-oder Biegevorgang während dem Anlassen oder Härten durchmachen. Für ein Regenerieren, also für das Wiederherstellen des ursprünglichen Profils von deformierten Profilstählen, ist diese bekannte Vorrichtung nicht verwendbar, da die in den Muffeln vorgesehenen Profilöffnungen lediglich Führungsöffnungen, welche auf die Form von relativ stark deformierten Profilstählen nicht einwirken können, sind.From DE-C No. 914862 a continuous device for hardening, tempering and bending or straightening thin-walled profile steels is known. In this known device, muffles made of heat-resistant material are used, which have the profile of the hardened material as a passage opening and embed it, the muffle either being able to be heated itself or being placed in a continuous furnace. This muffle is followed by a hardening unit, through which the material to be hardened runs and in which the profile bars are hardened, tempered, straightened or bent without losing shape and without residual stresses remaining in the profile. This device only ensures heat treatment of, in particular, thin-walled profile bars, which at the same time undergo an unspecified straightening or bending process during tempering or hardening. This known device cannot be used for regeneration, that is to say for restoring the original profile of deformed profile steels, since the profile openings provided in the muffles are merely guide openings which cannot act on the shape of relatively strongly deformed profile steels.

Durch die FR-A Nr. 1321911 ist eine Anlage zum Regenieren von Eisenbahnschienen bekannt, bei welcher die Schienen zuerst durch eine Wärmezone und anschliessend durch eine ganze Reihe von Bearbeitungszonen, wie Entgratungszone, Reprofilierungszone (Hämmer), Härtezone und Richtzone (Rollenbahn) hindurchgeführt werden. Ein einfaches Regenieren von unterschiedlichen offenen Profilstählen ist durch diese bekannte Anlage nicht möglich.From FR-A No. 1321911 a system for the regeneration of railroad tracks is known, in which the rails are first passed through a heating zone and then through a whole series of processing zones, such as deburring zone, reprofiling zone (hammers), hardening zone and straightening zone (roller conveyor) . A simple regeneration of different open profile steels is not possible with this known system.

Schliesslich ist durch die DE-B Nr. 1040885 ein Verfahren zum Kaltausrichten des Querschnittsprofils von gewalzten Schienen bekannt, bei welchem die Schiene durch eine Profildüse hindurchgezogen wird, wobei die Querschnittsfläche nicht oder höchstens geringfügig vermindert wird. Es handelt sich bei diesem bekannten Verfahren um ein Nachkalibrieren von gewalzten Schienen zum Zwecke der Erzielung eines Schienenprofils mit Innentoleranzen. Dieses bekannte Nachkalibrierverfahren ist zum Regenerieren von offenen Profilstählen nicht anwendbar.Finally, DE-B No. 1040885 discloses a method for cold-aligning the cross-sectional profile of rolled rails, in which the rail is pulled through a profile nozzle, the cross-sectional area being not or only slightly reduced. This known method involves recalibrating rolled rails for the purpose of achieving a rail profile with internal tolerances. This known recalibration method cannot be used to regenerate open profile steels.

Aufgabe der Erfindung ist es, eine Anlage zum Regenerieren von Profilstählen anzugeben, die die mehrmalige Verwendung von im Einsatz deformierten offenen Profilstählen ermöglicht.The object of the invention is to provide a system for the regeneration of profile steels, which enables repeated use of deformed open profile steels in use.

Diese Aufgabe wird erfindungsgemäss durch eine Anlage zum Regenerieren von offenen Profilstählen mit einer Wärmezone, einer Kühlzone und mit mindestens einer dem benötigten Profil entsprechenden Profilöffnung dadurch gelöst, dass die Wärmezone Brenner enthält, dass die Profilöffnung in mindestens einer, in einem Gehäuse angeordneten, auswechselbaren Ziehmatrize vorgesehen ist und dass eine Ziehvorrichtung vorgesehen ist, mit welcher der zu regenerierende Profilstahl mittels Stahlseil und Dornen verbunden ist.This object is achieved according to the invention by a system for the regeneration of open profile steels with a heating zone, a cooling zone and with at least one profile opening corresponding to the required profile in that the heating zone contains burners in that the profile opening in at least one exchangeable drawing die arranged in a housing is provided and that a pulling device is provided, with which the section steel to be regenerated is connected by means of a steel cable and mandrels.

Die Anlage kann ausserdem vorteilhafterweise mit einer nach der Ziehmatrize angeordneten Berieselungsvorrichtung als Kühlzone ausgerüstet sein, welche einen Kühlflüssigkeitsbehälter und Berieselungsdüsen enthält.The system can also advantageously be equipped with a sprinkler device arranged after the drawing die as a cooling zone, which contains a coolant tank and sprinkler nozzles.

Ein Vorteil der Anlage nach der Erfindung besteht darin, dass ganz oder beinahe ganz Verluste an Profilen vermieden werden können und ein mehrfaches Nutzen von Profilen ohne Begrenzung des Einsatzbereiches ermöglicht wird.An advantage of the system according to the invention is that losses in profiles can be avoided entirely or almost entirely and that profiles can be used more than once without limiting the area of use.

Nachstehend wird die Erfindung anhand eines Ausführungsbeispiels unter Bezug auf die Zeichnung näher erläutert. Die Zeichnung zeigt schematisch eine Anlage zur Regenerierung offener Profilstähle.The invention is explained in more detail below using an exemplary embodiment with reference to the drawing. The drawing shows schematically a plant for the regeneration of open profile steels.

Die erfindungsgemässe Regenerierungsanlage besteht aus einer Anzahl regulierbarer (Azetylen-) Brenner 1, mit Hilfe derer ein zu regenerierender Profilstahl 2 auf die entsprechende metallplastizierende Temperatur vorgewärmt wird, aus einem stationären Gehäuse 3 mit einer auswechselbaren Ziehmatrize 4 mit einer Profilöffnung 5 in Form des entsprechenden Profils, z.B. für Spundwandstahl, aus einem Kühlflüssigkeitsbehälter 6, Berieselungsdüsen 7, einer mechanischen Profilziehvorrichtung 8 und einem Stahlseil 9, welches mit einem Dorn 10, der in eine vorgebohrte Öffnung im Spundwandstahl eingesetzt wird, ausgerüstet ist.The regeneration system according to the invention consists of a number of adjustable (acetylene) burners 1, by means of which a profile steel 2 to be regenerated is preheated to the corresponding metal-plating temperature, from a stationary housing 3 with an exchangeable drawing die 4 with a profile opening 5 in the form of the corresponding profile , e.g. for sheet pile steel, from a coolant tank 6, sprinkler nozzles 7, a mechanical profile pulling device 8 and a steel cable 9, which is equipped with a mandrel 10, which is inserted into a pre-drilled opening in the sheet pile steel.

Die erfindungsgemässe Regenerierungsanlage funktioniert folgendermassen.The regeneration system according to the invention functions as follows.

Der zu regenerierende Profilstahl 2 wird mit dem weniger deformierten Ende in die Profilöffnung 5 der Ziehmatrize 4 eingelegt, worauf in die entsprechend vorgebohrte Öffnung 11 des Profilstahls 2 der Dorn 10 des Stahlseils 9, welches auf die Trommel der mechanischen Ziehvorrichtung 8 aufgewickelt ist, eingesetzt wird. Der Profilstahl 2 wird danach auf die metallplastizierende Temperatur erwärmt, wonach er durch die Profilöffnung 5 der Ziehmatrize 4 gezogen wird. Nachdem dessen entsprechende Form erreicht ist, wird der Profilstahl 2 mit kaltem Wasser oder einer anderen Flüssigkeit aus dem Kühlflüssigkeitsbehälter 6 mit Hilfe der Berieselungsdüsen 7 abgekühlt.The profile steel 2 to be regenerated is inserted with the less deformed end into the profile opening 5 of the drawing die 4, whereupon the mandrel 10 of the steel cable 9, which is wound onto the drum of the mechanical drawing device 8, is inserted into the correspondingly predrilled opening 11 of the profile steel 2 . The section steel 2 is then heated to the plasticizing temperature, after which it is drawn through the section opening 5 of the drawing die 4. After its corresponding shape is reached, the section steel 2 is cooled with cold water or another liquid from the cooling liquid container 6 with the aid of the sprinkling nozzles 7.

Auf die beschriebene Weise können einfach verzogene Profilstähle ausgerichtet und danach erneut wieder eingesetzt werden.In the described manner, simply warped profile steels can be aligned and then re-used.
