Entsprechende dem Stand der Technik zu entnehmende Maßnahmen sind aufwendig und somit kostenintensiv.Appropriate measures to be taken from the prior art are complex and thus expensive.

Der vorliegenden Erfindung liegt das Problem zu Grunde, einen Rillengleisabschnitt bzw. ein Verfahren zum Ausbilden eines solchen derart weiterzubilden, dass überaus präzise und mit konstruktiv einfachen Maßnahmen kostengünstig gezielt Bereiche einer Rille mit verschleißfestem Material versehen werden können.The present invention is based on the problem of a grooved track section or a To further develop methods for forming such a way that extremely precise and with structurally simple measures cost-effectively targeted areas of a groove with wear-resistant Material can be provided.

Erfindungsgemäß wird das Problem durch einen Rillengleisabschnitt der eingangs genannten Art im Wesentlichen dadurch gelöst, dass der Gleisabschnitt aus einem Konstruktionsprofil mit Vollkopfprofil besteht, dass in dessen Kopf im Bereich zumindest einer Ausnehmung eingearbeitet und mit verschleißfestem Material ausgefüllt ist und dass die ausgefüllte Ausnehmung von der nach dem Ausfüllen der Ausnehmung ausgebildeten Rille geschnitten ist. Dabei ist insbesondere die Ausnehmung wie Nut durch Auftragsschweißen ausgefüllt, wobei mehrere Lagen mit gegebenenfalls voneinander abweichenden Materialeigenschaften vorgesehen sein können.According to the invention, the problem is solved by a grooved track section as mentioned at the beginning Art essentially solved in that the track section with a construction profile Full head profile exists that in its head in the area of at least one recess incorporated and filled with wear-resistant material and that the filled Recess is cut by the groove formed after filling the recess. In this case, the recess, in particular the groove, is filled by cladding, whereby several layers with material properties that may differ from one another are provided could be.

Ferner kann die Aussparung oder Ausnehmung eine Tiefe t mit 10 mm ≤ t ≤ 30 mm, insbesondere t in etwa 20 mm und/oder eine Breite b mit 3 mm ≤ b ≤ 15 mm, insbesondere b in etwa 8 mm - 10 mm aufweisen.Furthermore, the recess or recess can have a depth t with 10 mm t t 30 30 mm, in particular t approximately 20 mm and / or a width b with 3 mm ≤ b ≤ 15 mm, in particular b in have about 8 mm - 10 mm.

Ein Verfahren zum Vergüten einer Rillenkante oder -flanke eines Rillengleisabschnitts mit verschleißfestem Material zeichnet sich durch die Verfahrensschritte aus:

  • Einarbeiten einer Ausnehmung in einem Kopf eines ein Vollkopfprofil aufweisenden Konstruktionsprofils im Bereich vorzusehender Rille,
  • Ausfüllen der Ausnehmung mit verschleißfestem Material und
  • Ausbilden der Rille, deren Verlauf die Ausnehmung schneidet.
A process for tempering a groove edge or flank of a grooved track section with wear-resistant material is characterized by the process steps:
  • Incorporation of a recess in a head of a construction profile with a full head profile in the area of the groove to be provided,
  • Filling the recess with wear-resistant material and
  • Form the groove, the course of which intersects the recess.

Dabei wird die Ausnehmung wie Nut insbesondere durch Auftragsschweißung ausgefüllt, wobei mehrere Lagen mit gegebenenfalls unterschiedlichen Materialeigenschaften ausgebildet werden können.The recess, like the groove, is filled in in particular by cladding, wherein several layers with possibly different material properties are formed can be.

Die Ausnehmung wie Nut selbst wird mit einer Tiefe t mit 10 mm ≤ t ≤ 30 mm und/oder einer Breite b mit 3 mm ≤ b ≤ 15 mm in den Kopf des Konstruktionsprofils eingearbeitet. Sodann wird in die Ausnehmung wie Nut insbesondere durch Auftragsschweißung als Material ein solches mit einem Zusatzwerkstoff eingebracht, der sowohl für Verbindungsschweißung zum Beispiel für hochlegierte rostfreie Stähle und Mischverbindungen zwischen diesen und normalen Baustählen als auch als Auftragswerkstoffe für Schienen und Weichenteile üblich ist.The recess like the groove itself has a depth t of 10 mm ≤ t ≤ 30 mm and / or one Width b with 3 mm ≤ b ≤ 15 mm worked into the head of the construction profile. Then is in the recess like a groove, in particular by build-up welding as a material introduced with a filler metal, which is used both for connection welding Example of high-alloy stainless steels and mixed connections between them and normal structural steels as well as custom materials for rails and switch parts.

Durch die erfindungsgemäße Lehre kann gezielt der Bereich des Kopfes mit verschleißfestem Material versehen werden, in dem einem hohen Verschleiß ausgesetzte Kanten bzw. Flanken einer Rille verlaufen. Somit kann eine optimale Ausnutzung eingebrachten Schweißgutes erfolgen. Außerdem wird eine Qualitätsverbesserung in den erzielbaren Form- und Lagetoleranzen sowie eine höhere Oberflächengüte erreicht. Ferner ist von Vorteil, dass sich eine bessere Wirtschaftlichkeit ergibt, d. h. bei weniger Arbeitsaufwand kann ein größerer Bereich der zu schützenden Fahr- bzw. Leitkanten schweißtechnisch vergütet werden. Hierzu erfolgt das Ausbilden der Rille sowie die Oberflächenbehandlung des vergüteten Bereichs in einem Arbeitsgang, nämlich beim Einarbeiten wie Fräsen der Rille.Through the teaching of the invention, the area of the head can be targeted with wear-resistant Material are provided in the edges or flanks exposed to high wear run a groove. This means that the weld metal can be used optimally respectively. In addition, there is a quality improvement in the achievable shape and position tolerances as well as a higher surface quality. It is also advantageous that a better Profitability results in d. H. With less work, a larger area can be added protective driving or leading edges are welded. This is done for this Forming the groove and the surface treatment of the tempered area in one Operation, namely when working in, such as milling the groove.

Dadurch, dass ein Schweißen in einem Vollmaterial erfolgt, ist eine bessere Wärmeführung im Vergleich zum Auftragsschweißen im Bereich einer bereits ausgearbeiteten Rille möglich. Auch besteht die Möglichkeit eines gezielteren und kontrollierten Vorwärmens. All diese Möglichkeiten bietet der Stand der Technik nicht, nach dem im Bereich einer bereits vorhandenen Rille ein Schweißen erfolgt.The fact that welding takes place in a solid material means that heat is better conducted in the Can be compared to cladding in the area of an already prepared groove. Also there is the possibility of a more targeted and controlled preheating. All these The state of the art does not offer any possibilities, as in the area of one existing groove is welded.

Weitere Einzelheiten, Vorteile und Merkmale der Erfindung ergeben sich nicht nur aus den Ansprüchen, den diesen zu entnehmenden Merkmalen - für sich und/oder in Kombination -, sondern auch aus der nachfolgenden Beschreibung eines der Zeichnungen zu entnehmenden bevorzugten Ausführungsbeispiels.Further details, advantages and features of the invention result not only from the Claims, the features to be extracted from these - individually and / or in combination -, but also from the following description of one of the drawings preferred embodiment.

In Fig. 1 ist ein Querschnitt durch eine Rillenschiene 10 mit Fuß 12, Steg 14 und Kopf 16 dargestellt, in dem eine Rille 18 zum Führen eines Rades eingearbeitet ist. Um die einem besonderen Verschleiß ausgesetzten Fahr- bzw. Leitkanten 20, 21 zu vergüten, d.h. mit einem verschleißfesten Material insbesondere durch Auftragsschweißung zu versehen, wird als Ausgangsmaterial ein Konstruktionsprofil mit Vollkopfprofil benutzt, also ein solches ohne ausgebildete Rille. Ein Kopf 24 eines entsprechenden Konstruktionsprofils ist in der Fig. 2 dargestellt. Der Bereich, in dem die Rille 18 eingearbeitet werden soll, ist punktstrichiert. Bei dem Konstruktionsprofil kann es sich z. B. um eine Dickstegschiene, ein Vierkantprofil oder sonstiges Profilelement mit Vollkopf handeln.In Fig. 1 is a cross section through a grooved rail 10 with foot 12, web 14 and head 16th shown, in which a groove 18 is incorporated for guiding a wheel. To the one to compensate for driving or leading edges 20, 21 exposed to particular wear, i.e. with a Providing wear-resistant material, in particular by cladding, is called Starting material used a construction profile with full head profile, i.e. one without trained groove. A head 24 of a corresponding construction profile is shown in FIG. 2 shown. The area in which the groove 18 is to be incorporated is dotted. At the construction profile can be z. B. a thick web rail, a square profile or trade other profile element with full head.

Um die Bereiche der Kanten 20, 21 mit verschleißfestem Material zu versehen, werden zunächst von der Fahrfläche 26 des Kopfes 24 ausgehend Nuten 28, 30 eingearbeitet, die von den Kanten 20, 21 der später auszubildenden Rille 18 geschnitten werden. Sodann werden die Nuten 28, 30 durch Auftragsschweißen vorzugsweise mehrlagig ausgefüllt (Bereiche 31, 33), wobei dem Schweißmaterial Zusatzwerkstoffe zugegeben werden, die die gewünschten verschleißarmen Eigenschaften aufweisen. Nach Ausfüllen der Nuten 28, 30 wird sodann die Rille 18, die erwähntermaßen die Nuten 28, 30 schneiden, eingearbeitet.In order to provide the areas of the edges 20, 21 with wear-resistant material grooves 28, 30, starting from the driving surface 26 of the head 24, are machined in the edges 20, 21 of the groove 18 to be formed later are cut. Then the Grooves 28, 30 preferably filled in multiple layers by cladding (areas 31, 33), additional materials are added to the welding material, which have the desired low wear Have properties. After filling the grooves 28, 30, the groove is then 18, which cut the grooves 28, 30 mentioned, incorporated.

Dies bedeutet, dass die Nachbearbeitung der Auftragsschweißung und die Herstellung der Rille 18 in einem gemeinsamen Arbeitsgang durchgeführt wird, wodurch sich eine Erhöhung der Wirtschaftlichkeit ergibt. Ferner können problemlos größere Bereiche der zu schützenden Fahr- und Leitkanten schweißtechnisch vergütet werden. So können die die Rille 18 begrenzenden Flanken 32, 34 bis zu einer Breite b von zum Beispiel 8 mm oder mehr aus verschleißfestem Material bestehen, wobei von der Fahrfläche 26 ausgehend Tiefen t von zum Beispiel 20 mm schweißtechnisch vergütet sein können. Mit anderen Worten kann mit weniger Arbeitsaufwand ein größerer Bereich der zu schützenden Kanten bzw. Flanken der Rille 18 schweißtechnisch vergütet werden.This means that the finishing of the surfacing and the production of the groove 18 is carried out in a common operation, which increases the Profitability results. Furthermore, larger areas of the driving and leading edges are welded. This can limit the groove 18 Flanks 32, 34 up to a width b of, for example, 8 mm or more made of wear-resistant Material consist, starting from the driving surface 26 depths t of, for example, 20 mm can be welded. In other words, with less work a larger area of the edges or flanks of the groove 18 to be protected is welded be compensated.
