Description

Die Erfindung betrifft eine Schraubensicherung in Gestalt einer an mehreren Stellen wellenförmig aus der Scheibenebenc abgebogenen Unterlagscheibe und bezweckt, eine Sicherung dieser Art zu schaffen, die annähernd zum Preise einer gewöhnlichen ■ Unterlagscheibe hergestellt werden kann. Dies ist erfindungsgemäß dadurch erreicht worden, daß die Abbiegungen nur in der Nähe des Umfanges und in einem derartigen Ausmaße ausgebildet sind, wie sie durch eine am Umfang wellenförmige Stanzpatrize in Verbindung mit einer gewöhnlichen ebenen Matrize erzeugt werden können. 1S Die Abbildungen zeigen ein Ausführungsbeispiel der Erfindung, und zwar Fig. 1 eine Unterlagscheibe im Aufriß, Fig. 2 im Grundriß, Fig. 3 im Schnitt. Die Fig. 4 bis 6 zeigen die Unterlagsdieibe in der Anwendung als Schraubensicherung, Fig. 7 das Werkzeug zu ihrer Herstellung.The invention relates to a screw locking device in the form of a washer bent in a wave shape from the washer plane at several points and aims to create a locking device of this type which can be produced approximately at the price of an ordinary washer. According to the invention, this has been achieved in that the bends are only formed in the vicinity of the circumference and to the extent that they can be produced by a stamping die which is undulating on the circumference in conjunction with a common flat die. 1 S The figures show an embodiment of the invention, namely Fig. 1 shows a washer in elevation, Fig. 2 in plan view, Fig. 3 in section. FIGS. 4 to 6 show the washers used as screw locking devices, and FIG. 7 shows the tool for their production.

Am äußeren Umfang der Unterlagscheibe sind drei Abbiegungen' vorhanden, so daß die Scheibe auf den drei Punkten uv iu und u3 aufliegt. Eine solche Dreipunktauflage gewährleistet bekanntlich eine besonders gute und gleichmäßige Spannung. Bei Fig. 4 ist die Schraubenmutter nicht festgezogen, sondern noch locker. Beim Anziehen der Schraubenmutter wölben sich gemäß Fig. 5 die umgebogenen Lappen der Scheibe wulstartig leicht nach oben und bilden somit eine Verriegelung gegen selbsttätiges Lösen der Mutter.. Fig. 6 zeigt den Grundriß zu Fig. 5.There are three bends on the outer circumference of the washer, so that the washer rests on the three points u v iu and u 3. As is known, such a three-point support ensures particularly good and even tension. In Fig. 4, the nut is not tightened, but still loose. When the screw nut is tightened, as shown in FIG. 5, the bent lobes of the disk bulge slightly upwards and thus form a lock to prevent the nut from loosening automatically. FIG. 6 shows the plan of FIG.

Abbiegungen in Richtung senkrecht zur Scheibenebene und tangential zum Umfang erfordert nach dem Ausschneiden kernen weiteren Arbeitsgang unter einem besonderen 4» Biegewerkzeug, Vielmehr besteht die Möglichkeit, die endgültige Form bereits im · Schnittwerkzeug zu erzeugen. Bei dem in Fig. 7 abgebildeten Folgeschnittwerkzeug wird beispielsweise der Werkstoff von links nach 4S rechts in Pfeilrichtung eingeschoben, mittels Stempels α vorgelocht und mittels Stempels b ausgeschnitten. Letzterer Stempel, die sog. Stanzpatrize ist an seiner unteren Schnittseittwellenförmig· ausgebildet, so daß untern 50 fertige Scheiben anfallen. Da diese Abbiegungen durch eine abschälende Wirkung der nach unten vorspringenden Teile der Stanzpatrize b erzeugt werden, ist ein Gegengesenk nicht erforderlich. Vielmehr genügt eine ge- 55 wohnliche ebene Schnittplatte als Matrize. Dies bedeutet einen erheblichen wirtschaftlichen Vorteil.Bends in the direction perpendicular to the plane of the disk and tangential to the circumference require further work after the cutting out with a special bending tool. Rather, it is possible to create the final shape in the cutting tool. In the illustrated in Fig. 7 progressive die, the material from left to 4 S is pushed to the right in the direction of arrow, for example, pre-punched by the punch α and cut by means of punch b. The latter punch, the so-called punching die, is designed in the shape of a wave on its lower side of the cut, so that there are 50 finished slices. Since these bends are produced by a peeling action of the downwardly projecting parts of the punching die b , a counter-die is not required. Rather, a comfortable, flat cutting plate is sufficient as a die. This means a considerable economic advantage.
