Description

Die Erfindung betrifft ein Fertigungsverfahren für eine Zungenvorrichtung, die insbesondere für Straßenbahngleise geeignet ist.The invention relates to a manufacturing method for a tongue device, which is particularly suitable for tram tracks.

Entweder werden Zungenvorrichtungen mit einem Zungenbett, auf dem eine Weichenzunge hin- und hergleiten kann, aus einzelnen Teilen zusammengebaut oder aber aus einem Vollblock herausgefräst. Wenn nicht Kostengründe dagegen sprechen, werden Zungenvorrichtungen vorzugsweise in einer solchen Monoblock-Konstruktion hergestellt, weil diese Monoblock-Konstruktion spannungsfrei und unter engeren Maschinentoleranzen herstellbar ist. Als Stand der Technik werden DE 10 2004 048 751 B3 und DE 92 18 808 U1 genannt.Either tongue devices with a tongue bed on which a switch tongue can slide back and forth, assembled from individual parts or milled out of a solid block. If not cost reasons speak against tongue devices are preferably made in such a monoblock construction, because this monoblock construction is stress-free and can be produced under narrower machine tolerances. As state of the art DE 10 2004 048 751 B3 and DE 92 18 808 U1 called.

Die hohe Fertigungsgenauigkeit der Monoblock-Konstruktion ist mit einer aus mehreren Komponenten zu fertigenden Konstruktion nicht zu erreichen. Die Monoblock-Konstruktion stellt ein homogenes Bauteil dar, in welchem sich die Wärme einer elektrischen Weichenheizung optimal in der gesamten Zungenvorrichtung verteilt. Außerdem bleibt die Wärme länger in der Monoblock-Konstruktion gespeichert, vergl. Firmenprospekt der Vossloh Laeis GmbH & Co. KG "Zungenvorrichtung in Monoblock-Konstruktion".The high production accuracy of the monobloc construction can not be achieved with a construction that can be manufactured from several components. The monoblock construction represents a homogeneous component, in which the heat of an electric point heater optimally distributed throughout the tongue device. In addition, the heat is stored longer in the monobloc construction, see company brochure of Vossloh Laeis GmbH & Co. KG "Tongue device in monobloc construction".

Aufgabe der Erfindung ist es, ein Fertigungsverfahren für eine möglichst kostengünstige Zungenvorrichtung vorzuschlagen, wobei die Zungenvorrichtung engste Toleranzen einhalten muss.The object of the invention is to propose a manufacturing method for the most cost-effective tongue device, wherein the tongue device must comply with the tightest tolerances.

Der Erfindung liegt die Erkenntnis zu Grunde, dass die zwei konkurrierenden Bauweisen der vorbeschriebenen Konstruktionen bekannter Zungenvorrichtungen kombinierbar sind.The invention is based on the recognition that the two competing designs of the above-described constructions of known tongue devices can be combined.

Die Aufgabe wird durch die kennzeichnenden Merkmale des Anspruchs 1 bzw. des Anspruchs 5 in Verbindung mit den jeweiligen Oberbegriffsmerkmalen gelöst.The object is achieved by the characterizing features of claim 1 and of claim 5 in conjunction with the respective preamble features.

Weitere vorteilhafte Ausgestaltungen der Erfindung bilden die Gegenstände der jeweiligen Unteransprüche.Further advantageous embodiments of the invention form the subject of the respective subclaims.

Gemäß dem erfindungsgemäßen Fertigungsverfahren für eine Zungenvorrichtung wird zunächst mindestens eine Komponente der Zungenvorrichtung auf eine ein Zungenbett bildende Grundplatte aufgeschweißt. Anschließend wird die Zungenvorrichtung umfassend die Grundplatte und die mindestens eine verschweißte Komponente nachbearbeitet, insbesondere mittels eines spanenden Fertigungsverfahrens.According to the manufacturing method for a tongue device according to the invention, first at least one component of the tongue device is welded onto a base plate forming a tongue bed. Subsequently, the tongue device comprising the base plate and the at least one welded component is post-processed, in particular by means of a machining production process.

Eine vorteilhafte Ausführungsform des Fertigungsverfahrens sieht vor, dass das Nachbearbeiten der Zungenvorrichtung mit sämtlichen nachzubearbeitenden Komponenten in einer einzigen Aufspannung mit Bezug auf einen einzigen Nullpunkt für alle Komponenten der Zungenvorrichtung erfolgt.An advantageous embodiment of the manufacturing method provides that the post-processing of the tongue device with all nachzubearbeitenden components in a single setup with respect to a single zero point for all components of the tongue device.

In weiteren vorteilhaften Ausführungsformen des erfindungsgemäßen Fertigungsverfahrens wird als Komponente zunächst mindestens eine der folgenden auf- bzw. unter die Grundplatte angeschweißt: Backenschiene, Beischiene, Schmutzkasten, Gleitstuhl, Zungenanschweißschiene, Zungenklemmblock.In further advantageous embodiments of the manufacturing method according to the invention, at least one of the following is welded on or under the base plate as a component: stock rail, runner, dirt box, slide chair, tongue welding rail, tongue clamping block.

Eine Zungenvorrichtung wird nach einem der vorbeschriebenen Fertigungsverfahren hergestellt. Die Zungenvorrichtung besteht mindestens aus einer Grundplatte und den mit der Grundplatte verschweißten Komponenten Backenschiene und Beischiene sowie aus einer beweglichen Weichenzunge, wobei eine spanende Bearbeitung der verschweißten Komponenten auf Endmaß nach deren Verschweißen erfolgt ist. Zungenvorrichtungen gemäß vorteilhafter Ausführungsformen weisen Bearbeitungsflächen auf, deren Toleranzfeld von etwa 3 mm um 2/3 auf etwa 1 mm gegenüber vorgegebenen Werten reduziert ist.A tongue device is manufactured according to one of the above-described manufacturing methods. The tongue device consists of at least one base plate and the welded to the base plate components rail and Beischiene and a movable switch blade, wherein a machining of the welded components has been made in gauge after their welding. Tongue devices according to advantageous embodiments have working surfaces whose tolerance field is reduced from about 3 mm by 2/3 to about 1 mm in relation to predetermined values.

Die Fertigung in geänderter Fertigungsreihenfolge mit den Mitteln der Monoblock-Bauweise, nämlich entsprechend großer CNC-Fräsmaschinen, ermöglicht eine Verwendung rohere Einzelteile mit Übermaß als Komponente und deren grobe Positionierung auf eine übliche Grundplatte. Es kommt zu einem gegenüber der bekannten Konstruktion aus Einzelteilen besonders schnellen Positionieren der Komponenten, da weniger genau positioniert werden muss. Außerdem ist bei den Komponenten nicht zu berücksichtigen, inwiefern thermische Einflüsse des Verschweißens vorgefertigte Anschlussoberflächen beeinträchtigen. Eine Bearbeitung, bei der solche Anschlussoberflächen gefertigt werden, erfolgt erst nach dem Positionieren und Anschweißen der Komponenten in einem nachrangigen Fertigungsschritt. Insgesamt ergeben sich deutliche Kostenvorteile gegenüber der bekannten Monoblock-Konstruktion sowie eine höhere Präzision gegenüber der bekannten Konstruktion aus Einzelteilen.The production in a modified manufacturing order by the means of monobloc construction, namely correspondingly large CNC milling machines, allows use of raw items with oversize as a component and their rough positioning on a conventional base plate. It comes to a comparison with the known construction of parts particularly fast positioning of the components, as less accurate positioning must be. In addition, the components do not take into account the extent to which the thermal effects of welding impair prefabricated connection surfaces. Machining in which such connection surfaces are manufactured takes place only after the positioning and welding of the components in a subordinate production step. Overall, there are significant cost advantages over the known monoblock construction and a higher precision compared to the known construction of individual parts.
