UFederringw U spring washer
Zusatz zu P 30 03 244.1-12 Die Erfindung betrifft eine weitere Ausbildung des eigenen älteren Vorschlages. Addition to P 30 03 244.1-12 The invention relates to a further training of your own older proposal.
Um Federringe der DIN 127, 128, 7980 und/oder 43699 als Schraubensicherung verwenden zu können wird vorgeschlagen, daß auf der Ober- und Unterfläche zahnartige Vorsprünge vorgesehen sind.Around spring washers of DIN 127, 128, 7980 and / or 43699 as screw locking to be able to use it is proposed that tooth-like on the upper and lower surfaces Projections are provided.
Die Anordnung dieser Verzahnung bringt überraschender Weise den gewunschten Erfolg.The arrangement of these teeth surprisingly brings the desired Success.
Hierdurch sind die Federringe neuen Verwendungen, nämlich als Schraubensicherung, zugänglich.As a result, the spring washers are new uses, namely as screw locking, accessible.
Vorteilhafte Weiterbildungen sind in den Ansprüchen 2 bis 5 bezeichnet.Advantageous further developments are identified in claims 2 to 5.
Da der Federring, wenn er aus der länglichen Drahtform in die runde Ringform überführt werden soll, nicht mit der Verzahnung am Umformwerkzeug anliegen darf, weil dieses die Verzahnung beschädigen könnte, ist in Weiterbildung vorgesehen, daß die Innenfläche des Federringes a s Hohlkehle ausgebildet ist.Because the spring washer when it is from the elongated wire shape into the round one Ring shape is to be transferred, do not rest with the teeth on the forming tool may, because this could damage the toothing, is provided in further training, that the inner surface of the spring ring is formed as a s groove.
Die Hohlkehle kann als Zentrierung und puhrung für das Umformwerkzeug dienen, wie es analog in Fig. 6 des älteren Vorschlages gezeigt ist.The fillet can be used as a centering and puhrung for the forming tool serve as it is shown analogously in Fig. 6 of the older proposal.
Weitere Vorteile ergeben sich aus den Ansprüchen 7 bis 11.Further advantages result from claims 7 to 11.
Eine bevorzugte Verfahrensweise ist in den Ansprüchen 12 bis 14 bezeichnet.A preferred procedure is specified in claims 12-14.
Der beispielsweise runde Draht (Ausgangsmaterial) wird zu einem Trapezquerschnitt umgeformt, in dessen Ober- und Unterfläche Zähne eingewalzt werden.The round wire (starting material), for example, becomes a trapezoidal cross-section formed, teeth are rolled into its upper and lower surface.
Anschließend wird der Ring geformt und abgeschnitten.Then the ring is shaped and cut off.
Es ist auch möglich, den profilierten Draht (z.B. rapezprofil) abschnittsweise vor der Bildung des Ringes, beispielsweise im Takt des Schneidegerätes, in einem Stanzvorgang mit der Verzahnung zu versehen.It is also possible to use the profiled wire (e.g. rapez profile) in sections before the formation of the ring, for example in time with the cutting device, in one To provide the punching process with the toothing.
Ein Ausfiihrungsbeispiel ist in der Zeichnung dargestellt und im folgenden näher beschrieben.An exemplary embodiment is shown in the drawing and below described in more detail.
Es zeigt: Fig. 1 bis 4 einen Verfahrensablauf zur Herstellung eines erfindungsgemaßen Federringes, Fig. 5 einen Federring in Draufsicht, Fig. 6 desgl. in Seitenansicht.It shows: FIGS. 1 to 4 a process sequence for producing a spring ring according to the invention, FIG. 5 a spring ring in plan view, FIG. 6 the same. in side view.
Ausgehend von einem metallischen Draht runden Querschnitts (Fig. 1) wird ein etwa trapezförmiges Profil hergestellt (Fig. 2), z.3. durch Ziehen oder Walzen.Starting from a metallic wire with a round cross-section (Fig. 1) an approximately trapezoidal profile is produced (Fig. 2), z.3. by dragging or Rollers.
Sofern der fertige Federring eine rechteckige Querschnittsform aufweisen soll, ist die trapezförmige Ausgangsprofilierung üblich und erforderlich.If the finished spring washer have a rectangular cross-sectional shape should, the trapezoidal starting profile is common and necessary.
Itas Profil wird beispielsweise in einem weiteren ieh- oder Walzvorgang so geformt, daß die innen-Liegende kurze Trapezfläche eine Hohlkehle 1 bildet.Ita's profile is used, for example, in a further heating or rolling process shaped in such a way that the short trapezoidal surface on the inside forms a fillet 1.
Die Hohlkehle 1 kann auch beim Profilieren des Drahtes gel eichze itig ausgebildet werden.The groove 1 can also gel eichze when profiling the wire itig be trained.
Zudem kann die auf der Ober- und Unterseite des Federringes vorzusehende Verzahnung 2 entweder kontinuierlich angewalzt oder diskontinuierlich eingestanzt werden.In addition, the one on the top and bottom of the spring washer can be provided Toothing 2 either rolled continuously or punched in discontinuously will.
Der fertig profilierte und mit Verzahnung versehene Draht wird einem Formwerkzeug zugeführt, daß in bekannter Weise den Federring formt und abtrennt. Der Trennvorgang kann ggf. gleichzeitig mit o.g. Zahnstanzvorgang ablaufen.The finished profiled and serrated wire becomes a Forming tool supplied that forms and separates the spring ring in a known manner. The cutting process can take place at the same time as the above-mentioned tooth punching process.
Die FUiir des Drahtes im Formwerkzeug erfolgt, wie in Fig. 4 schematisch dargestellt, mittels zwei Fänrungen 3,4 die, ohne die verzahnten Flächen des Ringes zu beschädigen, an der Hohlkehle 1 und an der Grundseite des Trapezes angreifen.The wire is fed in the forming tool, as is shown schematically in FIG. 4 shown, by means of two Fänrungen 3,4, without the toothed surfaces of the ring to damage, attack on the fillet 1 and on the base of the trapezoid.
Der fertige Federring ist in Fig. 5 und 6 gezeigt.The finished spring washer is shown in FIGS.
Dabei ist in Fig. 5 ein Federring mit kreuzweiser Verzahnung gezeigt.In this case, a spring ring with cross teeth is shown in FIG. 5.
Die Verzahnung kann gerundete Zähne, besser aber scharfkantige Zähne aufweisen.The toothing can have rounded teeth, but better sharp-edged teeth exhibit.
Der erfindungsgemäße Federring kann aus jedem geeigneten Material gefertigt sein. Durch die Verzahnung der Wirkungsflächen des Federringes (Ober-und Unterfläche) ist der federring als Schraubensicherung geeignet. Damit ist eine neue vielseitige Verwendungsmöglichkeit eröffnet.The spring ring according to the invention can be made of any suitable material be made. Due to the interlocking of the effective surfaces of the spring ring (upper and The spring lock washer is suitable as a screw locking device. So that's a new one Versatile use opens up.
Alle neuen in der Beschreibung und/oder Zeichnung offenbarten Einzel~ und Kombinationsmerkmale werden als erfindungswesentlich angesehen.All new items disclosed in the description and / or drawing and combination features are considered essential to the invention.
