Description

Verfahren zur Herstellung von Lagerteilen in Form von spitzigen Zapfen und Wellen aus nichtrostendem und höchstens schwach magnetischem Drahtmaterial Es ist bekannt, daß man in verschiedenen Apparaten und Instrumenten, insbesondere in billigen Uhren, zur Lagerung von Wellen Spitzenlagerungen anwendet. Hierzu weisen die Wellen an ihren Enden Spitzen auf, die in konischen Vertiefungen von Lagersteinen oder Metallagern gelagert sind. Solche Wellen bestehen aus Stahl, die durch bekannte Härteverfahren martensitisch gehärtet werden. Ein großer Nachteil derselben liegt darin, daß ihre Qualität bei der Serienherstellung ungleichmäßig ausfällt, so daß sie sortiert werden müssen, um nur diejenigen mit den den gestellten Anforderungen genügenden Lagerspitzen zur Verwendung zuzulassen.Process for the production of bearing parts in the form of pointed pins and shafts made of rustproof and at most weakly magnetic wire material Es is known to be used in various apparatus and instruments, especially in cheap clocks, uses point bearings to support shafts. Point to this the shafts have peaks at their ends, which are in conical depressions of bearing stones or metal bearings. Such shafts are made of steel that is known by Hardening process are hardened martensitically. A major disadvantage of the same lies in that their quality is uneven in series production, so that they need to be sorted to only those with the requirements allow sufficient bearing tips for use.

Die Erfindung bezieht sich nun auf ein Verfahren zur Herstellung von Lagerteilen in Form von spitzigen Zapfen und Wellen aus nichtrostendem und höchstens schwach magnetischem Drahtmaterial für Spitzenlagerungen in Apparaten und Instrumenten aller Art, bei dem die Lagerteile aus einem Drahtmaterial herausgearbeitet werden, nachdem es über 800° C erhitzt, dann abgeschreckt -und schließlich bis auf Festigkeitswerte von über 200 kg/mm2 und auf Härten von über 600 Vickers kalt heruntergezogen ist. Bei dem Glühen von über 800° C wird das Drahtmaterial homogenisiert, wird aber durch das Abschrecken nicht hart.The invention now relates to a method for producing Bearing parts in the form of pointed pins and shafts made of stainless and at most weakly magnetic wire material for tip bearings in apparatus and instruments of all kinds, in which the bearing parts are carved out of a wire material, after it has been heated to over 800 ° C, then quenched - and finally down to strength values of over 200 kg / mm2 and to hardnesses of over 600 Vickers is drawn down cold. When annealing at over 800 ° C, the wire material is homogenized, but is through the quenching is not hard.

Aus diesem Material werden dann die Lagerteile herausgearbeitet, z. B. herausgeschliffen, und zwar je nach Wunsch in Form von Zapfen mit einer Lagerspitze oder in Form von Wellen mit Lagerspitzen an beiden Enden.The bearing parts are then worked out from this material, e.g. B. ground out, depending on your requirements in the form of pins with a bearing tip or in the form of shafts with bearing tips at both ends.

Die Festigkeitswerte der Lagerteile werden noch verbessert durch eine Wärmebehandlung zwischen 200 und 600° C entweder des Drahtes vor dem Herausarbeiten oder der herausgearbeiteten Lagerteile.The strength values of the bearing parts are further improved by a Heat treatment between 200 and 600 ° C of either the wire before machining or the worked out storage parts.

Das folgende Beispiel veranschaulicht eine bevorzugte Durchführungsform der Erfindung.The following example illustrates a preferred implementation the invention.

Beispiel Eine für das Verfahren geeignete Erfindung ist die folgende: 40 bis 50% Co, 10 bis 20 % Cr, etwa 5% Mo, etwa 5'% W, 0,2 bis 411/o. Be, 0,8 bis 1,2 % Ti, etwa 2 °/o Mn + Si, 0 bis 10 % Fe, Rest Ni.Example An invention suitable for the method is the following: 40 to 50% Co, 10 to 20% Cr, about 5% Mo, about 5% W, 0.2 to 411 / o. Be, 0.8 to 1.2% Ti, about 2% Mn + Si, 0 to 10% Fe, balance Ni.

Es können aber auch andere Bruch- und rostsichere sowie schwach magnetische Legierungen verwendet werden.But other break-proof and rust-proof as well as weakly magnetic ones can also be used Alloys are used.

Die als Beispiel angeführte Legierung wird in Drahtform bei etwa l100° C geglüht und auf Zimmertemperatur abgeschreckt. Der so behandelte Draht wird kalt verformt, bis auf Festigkeitswerte von mindestens 200 kg/mm2. Aus diesem Draht werden die mit den Lagerspitzen versehenen Zapfen oder Wellen herausgearbeitet und nachträglich bei 400 bis 500° C während 1 bis 4 Stunden wärmebehandelt. Die so hergestellten Lagerteile haben Festigkeitswerte von über 200 kg/m2 und Härten von über 650 Vickers. Die Wärmebehandlung bei 400 bis 500° C kann anstatt an den herausgearbeiteten Lagerteilen am Draht selbst vorgenommen werden.The alloy given as an example is in wire form at about 1100 ° Annealed to C and quenched to room temperature. The wire treated in this way becomes cold deformed, up to strength values of at least 200 kg / mm2. This wire will become the journals or shafts provided with the bearing tips worked out and subsequently heat-treated at 400 to 500 ° C for 1 to 4 hours. The so produced Bearing parts have strength values of over 200 kg / m2 and hardnesses of over 650 Vickers. The heat treatment at 400 to 500 ° C can be used instead of the machined bearing parts can be done on the wire itself.

Auf Drähte, die nach obigen Beispielen behandelt wurden und kleine Durchmesser von z. B. 0,1 bis 0,52 mm aufweisen, können Kanülen aus einem weicheren Material, wie z. B. Messing, Neusilber, Berylliumbronze usw., geschoben werden. Aus diesem Verbunddraht, bestehend aus Kern und Hülse, können nun mit Lagerspitzen versehene Wellen herausgearbeitet werden. Bei solchen Wellen weist also nur der spitze Enden aufweisende Drahtkern den obenerwähnten hohen Härtegrad und den hohen Festigkeitswert auf, was insofern von Vorteil ist, als sich diese Wellen leichter verarbeiten lassen.On wires treated according to the examples above and small ones Diameter of z. B. 0.1 to 0.52 mm, cannulas can be made of a softer one Material such as B. brass, nickel silver, beryllium bronze, etc., are pushed. This composite wire, consisting of core and sleeve, can now be used with bearing tips provided waves can be worked out. With such waves, only the one shows pointed wire core having the above-mentioned high degree of hardness and the high Strength value, which is advantageous in that these waves are easier let process.
