Description

Die vorliegende Erfindung betrifft ein Verschlussteil für Weichenverschlüsse nach dem Oberbegriff des Patentanspruchs 1.The present invention relates to a closure part for switch closures according to the preamble of patent claim 1.

Der klassische Typ der heute immer noch in einer sehr großen Breite eingesetzten Verschlüsse für Weichen in Eisenbahn-Gleisanlagen erfordern für die genaue Einstellung der Lagepositionen der Weichenzungen im verschlossenen Zustand über Funktionsteile meist sogenannte Verschlussstempel. Diese Verschlussstempel definieren die Endlage der Weichenzunge an der Stockschiene. Es ist eine essentielle Funktion einer jeden Weiche, dass die eine Weichenzunge anliegend, die andere abliegend ist und dadurch verhindert wird, dass der Radkranz des die Zunge befahrenden Rades einer Achse des passierenden Zuges bei der anliegenden zwischen Stockschiene und Weichenzunge einfährt und damit eine Entgleisung ausgelöst wird. Die Folgen einer Entgleisung sind meist nicht nur die Beschädigung der Weiche sondern auch eine Beschädigung/Zerstörung des Weichenverschlusses.The classic type of today still used in a very large width closures for switches in railway track systems require for the exact adjustment of the position positions of the switch blades in the closed state on functional parts mostly so-called closure punches. These closure punches define the end position of the switch tongue on the floor rail. It is an essential function of each switch, that the one tongue blade adjacent, the other is lying down and is prevented by the rim of the tongue moving wheel of an axle of the passing train at the adjacent between the floor rail and switch blade enters and thus triggered a derailment becomes. The consequences of a derailment are usually not only damage to the switch but also damage / destruction of the switch lock.

Die heute verwendeten Verschlüsse, insbesondere das Prinzip des Jüdelverschlusses benötigt an mindestes einem Bauteil die Möglichkeit einer Anpassung an die Spurweite der Weiche, eine vom Weichenradius abhängige Grösse. Damit ist gewährleistet, dass die Zungen an der Stockschiene aufliegen.The closures used today, in particular the principle of Jüdelverschlusses needed on at least one component, the possibility of adaptation to the gauge of the switch, a size dependent on the turnout radius. This ensures that the tongues rest on the floor rail.

Im praktischen Einsatz verschleissen die Lagerbolzen bei hoher Belastung in relativ kurzer Zeit. Dieser Verschleiss erfordert periodisch den Ersatz der Lagerbolzen. Die Verschlussstempel werden dadurch direkt oder indirekt betroffen.In practical use wear the bearing pin under high load in a relatively short time. This wear periodically requires the replacement of the bearing pin. The closure stamps are thereby affected directly or indirectly.

Bis heute werden diese Verschlussstempel im Gesenk geschmiedet. Das ist jedoch wirtschaftlich gesehen nicht immer mit Gesenk möglich, wenn die benötigte Stückzahl einer bestimmten Ausführung in Relation zum Herstellverfahren klein ist. Zudem ist es aus Sicht der Logistik das Bestreben, möglichst wenig verschiedene Längen der Verschlussstempel am Lager zu halten.To date, these closure stamps are forged in the die. However, this is not always economically possible with die, if the required quantity of a particular design in relation to the manufacturing process is small. Moreover, from the point of view of logistics, it is the endeavor, if possible to keep little different lengths of the closure stamp in stock.

Es hat sich in der Metallverarbeitung gezeigt, dass die Möglichkeit, Schmiedeteile ohne Gesenk herstellen zu lassen, infolge des Verlustes der Fertigungsanlagen und der qualifizierten Fachleute nicht mehr möglich ist. Das führt zum Zwang für die Abnahme hoher Stückzahlen.It has been shown in metalworking that the possibility to have forgings without dies is no longer possible due to the loss of manufacturing equipment and qualified professionals. This leads to the compulsion for the purchase of large quantities.

In der Praxis wird eine nach einer Tabelle auf die jeweilige Weichengeometrie am besten passende und verfügbare Unterlänge aus dem Kollektiv der verfügbaren Verschlussstempel verwendet. Die Anpassung der exakten Länge zum Erreichen einer anliegenden Zunge wird durch Erwärmung des Schaftes des Verschlussstempels im Felde auf Rotglut und gezielten Hammerschlägen in Form einer Nachschmiedung zwecks Dehnung erreicht. Ein Vorgehen, welches sehr viel Erfahrung und Routine erfordert. Auch hier wird es zunehmend schwieriger, dafür qualifiziertes Personal zu engagieren. In Figur 1 sind mit Parametern charakterisierte Verschlussstempel gezeigt. Die vorstehend erwähnte Tabelle enthält für diese Parameter rein beispielhaft folgende Ausprägungen: rechts links A B E 1 2 385 - 31 3 4 390 - 31 5 6 530 6 37 In practice, a sub-length best suited and available according to a table to the respective turnout geometry is used from the collective of the available closing punches. The adaptation of the exact length to reach an adjacent tongue is achieved by heating the stem of the closure stamp in the field to red hot and targeted hammer blows in the form of a reforging for the purpose of stretching. A procedure that requires a lot of experience and routine. Again, it is increasingly difficult to hire qualified staff for this. In FIG. 1 are shown with parameters characterized seal. The above-mentioned table contains for these parameters purely by way of example the following characteristics: right Left A B e 1 2 385 - 31 3 4 390 - 31 5 6 530 6 37

In EP 1 378 417 B1 [1] ist bereits eine Lösung für einen zweckmäßigen Austausch von Komponenten - hier für einen Excenterbolzen - vorgeschlagen worden.
Die Schrift DE 24 15 278 A [2] offenbart einen Mittelverschluss für Schienenweichen bestehend aus:

  • einer zur Weichenbetätigung an beiden Enden in backenschieneseitig befestigten Führungen längsverschiebbaren Schieberstange;
  • an den Weichenzungen befestigte Anschlussstücke, die mit der Schieberstange in Verbindung stehen;
wobei jedes Anschlussstück zwischen zwei im Abstand voneinander an der Schieberstange befestigten Mitnehmern gleitbar auf der Schieberstange angeordnet ist. Diese Mitnehmer sind als Druckstücke mit einer Verzahnung ausgebildet.In EP 1 378 417 B1 [1] has already been a solution for a convenient replacement of components - has been proposed here for an eccentric pin.
The font DE 24 15 278 A [2] discloses a center fastener for rail switches consisting of:
  • a slide rail for longitudinally displaceable slide guides mounted on both ends in the bake rail side guides;
  • fittings attached to the switch blades, which communicate with the slide rod;
wherein each fitting is slidably mounted on the slide rod between two drivers mounted spaced apart on the slide rod. These drivers are designed as plungers with a toothing.

Es ist damit ein neuer Weg für eine wirtschaftliche Lösung zu suchen, welcher den einfachen und präzisen Unterhalt und die Sicherheit solcher Weichenverschlüsse weiterhin gewährleistet. Die logistische Situation und der Rückgang des Fachwissens und Könnens führen zu zunehmenden Schwierigkeiten bei der händischen Finalisierung des Austausches von Verschlussstempeln an den Weichenverschlüssen. Es wurden so viele unterschiedliche Typen von Verschlussstempeln mit in der Länge unterschiedlichen Massen gefertigt wie für die Einstellung nach der oben beschriebenen Methode der Längenanpassung mittels Hammer erforderlich waren.It is thus a new way to search for an economical solution, which continues to ensure the simple and accurate maintenance and safety of such point closures. The logistical situation and the decline of the Expertise and skills lead to increasing difficulties in the manual finalization of the exchange of seals at the point closures. There were so many different types of closure punches made with different length in the masses as were required for the adjustment by the method described above of length adjustment by hammer.

Die bestimmenden Kenngrössen bei den Verschlussstempeln für die Verwendung sind die wie folgt aufgeführt:The determining parameters for the closure dies for use are as follows:

i)

  • Einstell-Länge,
  • Weichenseite (rechts oder links),
  • der Achsenversatz der Gabel.
i)
  • Setting length,
  • Switch side (right or left),
  • the axis offset of the fork.

ii)
Als Schwierigkeit ist die Bearbeitung der geschmiedeten Werkstücke zu sehen. Es ist eine Bezugsfläche zu erstellen und gleichzeitig möglichst viele Flächen unbearbeitet zu belassen.ii)
The difficulty is the processing of the forged workpieces to see. It is necessary to create a reference surface while at the same time leaving as many surfaces as possible unprocessed.

Zur Herstellproblematik: Es sind keine Lösungen vorhanden, die Problematik in der Stahlindustrie mit dem Verlust von Fertigungsverfahren zu substituieren. Verfahren wie das Stumpfschweissen zweier Teile erfordern vom Werkstück geometrische Mindestabmessungen, welche in der vorliegenden Aufgabenstellung nicht gegeben sind.The manufacturing problem: There are no solutions to replace the problem in the steel industry with the loss of manufacturing processes. Processes such as butt welding of two parts require geometric minimum dimensions of the workpiece, which are not given in the present task.

Es ist somit für die Sicherstellung der Logistik, der Praktikabilität und der Wirtschaftlichkeit bei der Herstellung der Verschlussstempel ein vollständig neuer Ansatz erforderlich.Thus, a completely new approach is needed to ensure logistics, practicability and economics of making the closure dies.

Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde einen Verschlussstempel anzugeben, der eine vielseitige Verwendung erlaubt und somit eine Lagerhaltung von verschiedenen Verschlussteilen überflüssig macht.The present invention is therefore based on the object of specifying a closure stamp, which allows versatile use and thus makes a storage of different closure parts superfluous.

Diese Aufgabe wird durch die im Patentanspruch 1 angegebenen Merkmale gelöst. Vorteilhafte Ausgestaltungen der Erfindung sind in weiteren Ansprüchen angegeben.This object is achieved by the features specified in claim 1. Advantageous embodiments of the invention are specified in further claims.

Die erfindungsgemässe Lösung beruht auf dem Ansatz einer modularen Lösung:The solution according to the invention is based on the approach of a modular solution:

Das Funktionsteil - der Verschlussstempel gemäss dem Stand der Technik in Abbildung 1 - wird unterteilt in den Abstützkopf / Stempel mit Bohrung und in den Schaft und auf der anderen Seite der Kopf bzw. die Gabel mit den Lagerbohrungen.The functional part - the closure stamp according to the prior art in illustration 1 - is divided into the support head / punch with hole and in the shaft and on the other side of the head or the fork with the bearing bores.

Diese zwei Teile werden mit einer Schwalbenschwanzführung, welche eine Neigung zur Längsachse aufweist, zusammen gehalten. In die Berührungsfläche der zwei Teile ist nun mittig eine Schraube eingesetzt, welche die Schwalbenschwanzführung arretiert und eine Einstellung der Länge des Verschlussstempels mittels Verschiebung in der schräg verlaufenden Schwalbenschwanzführung ermöglicht.These two parts are held together with a dovetail guide which has an inclination to the longitudinal axis. In the contact surface of the two parts, a screw is now centrally used, which locks the dovetail guide and allows adjustment of the length of the closure ram by means of displacement in the oblique dovetail guide.

Dabei ist in einem Teil ein Gewinde geschnitten und im andern Halbteil ist die Bohrung auf den Schrauben-Aussendurchmesser gebohrt.In this case, a thread is cut in one part and in the other half part the hole is drilled on the outer diameter of the screw.

Der Schraubenkopf seinerseits steht mit der Auflagefläche, auf dem Teil der Führung welche keinen Gewindeeingriff aufweist, d.h. den Gewinde-Aussendurchmesser aufweist.The screw head, in turn, is in contact with the bearing surface on the part of the guide which is not threadedly engaged, i. having the thread outer diameter.

Die Erfindung wird nachfolgend anhand der Abbildungen beispielsweise näher erläutert. Dabei zeigen:The invention will be explained in more detail with reference to the figures, for example. Showing:

Figur 1

Die Figur 2 mit den verschiedenen Ansichten zeigt die Gliederung des Verschlussstempels 1. Wie auch für den Verschlussstempel 1 gemäss dem Stand der Technik weist dieser aus Kompatibilitätsgründen eine Lagerbohrung 6 in der Gabel und eine Bohrung 7 im Stempel 3 auf.The FIG. 2 with the various views shows the outline of the closure stamp 1. As well as for the closure stamp 1 according to the prior art, this has a bearing hole 6 in the fork and a hole 7 in the stamp 3 for compatibility reasons.

Mit der Zweiteilung des Verschlussstempels 1 in Gabel 2 und Stempel 3 wird nun eine Vielzahl von Einstellungen möglich: Gabel 2 und Stempel 3 sind über eine formschlüssige Verbindung 5 verschiebbar gekoppelt, dabei ist vorzugsweise eine mit einer Schwalbenschwanzführung 5 vorgesehen. Die funktionale Schnittzone ist so gelegt, dass die Lagergabel 2 mit ihrer Variation in der konstruktiven Gestalt den mit den unterschiedlichen Achsfluchten der Lagergabel 2 und der seitensymmetrische Teil durch eine Längeneinstellvorrichtung getrennt sind.With the division of the closure punch 1 in fork 2 and 3 punch a variety of settings is now possible: fork 2 and 3 punch are slidably coupled via a positive connection 5, it is preferably provided with a dovetail guide 5. The functional cutting zone is placed so that the bearing fork 2 with its variation in the structural design with the different axial alignment of the storage fork 2 and the side-symmetrical part are separated by a length adjustment.

Die Figur 3 zeigt einen Schnitt durch den in Gabel 2 und Stempel 3 gegliederten Verschlussstempel 1 mit der Längeneinstellung mittels einer Schraube 4. Dabei ist im Stempel 3 quasi hälftig ein Gewinde geschnitten und in der Gabel 2 ist lediglich eine Bohrung enthalten. Der zylindrische Kopf der Schraube 4 - vorzugsweise eine Inbusschraube 4 - wird dabei oben und unten in einer halbzylindrischen Ausbuchtung der Gabel 2 geführt. Die Anordnung von halbzylindrischer Ausbuchtung und Gewindeschnitt kann auch invers vorgenommen werden, also halbzylindrischer Ausbuchtung im Stempel 3 und Gewindeschnitt in der Gabel 2. Der Figur 3 kann der Krafteinwirkung FE bzw. Fe über die beiden mit Schwalbenschwanz 5 und Schraube 4 verbundenen Teile 2 und 3 entnommen werden.The FIG. 3 shows a section through the articulated in fork 2 and 3 punch seal stamp 1 with the length adjustment by means of a screw 4. In the stamp 3 quasi half a thread cut and in the fork 2 is only one hole included. The cylindrical head of the screw 4 - preferably an Allen screw 4 - is guided up and down in a semi-cylindrical bulge of the fork 2. The arrangement of semi-cylindrical bulge and thread cut can also be made inversely, ie semi-cylindrical bulge in the punch 3 and thread cut in the fork 2. Der FIG. 3 can the force F E or F e on the two with dovetail 5 and screw 4 connected parts 2 and 3 are removed.
