Description
"Gewindemutter""Threaded nut"
Die Erfindung betrifft eine Gewindemutter, die mit einem @ölsenförmigen Bund in ein Loch eines Bleches oder einer Platte paßgereckt einsetzbar ist und durch anschließende Verformung des Bundes zumindest gegen axiale Lageänderung gesichert wird.The invention relates to a threaded nut with an oil-shaped Bund can be inserted into a hole in a sheet or plate and fits right through subsequent deformation of the federal government at least secured against axial change in position will.
Derartige Gewindemuttern sind bereits der DE-AS 1 123 524 sowie der US-PS 2 026 757 als bekannt zu entnehmen. Diese bekannten Muttern weisen jedoch den Nachteil auf, daß durch den ungebördelten Teil des Bundes bei hochbeauspruchten Schraubverbindungen große Flächenpressungen in einem ringförmigen Bereich des Werkstückes entstehen. Bei z.B. für den Betrieb eines Kraftwagens wichtigen Pauteilen kann dies zu einer großen Gefahr werden.Such threaded nuts are already DE-AS 1 123 524 and the US Pat. No. 2,026,757 as known. However, these known nuts have the disadvantage that due to the unflared part of the federal government at hochbeauspruchten Screw connections large surface pressures in an annular area of the workpiece develop. This can be the case with components that are important e.g. for the operation of a motor vehicle become a great danger.
Der vorliegenden Erfindung lag daher die Aufgabe zugrunde, diesen Nachteil zu verr.ieiden und eine Gewindemutter der eingangs geschillerten Art zu schaffen, bei der eine gleichmäßige Kraft @n@@@@ung i@ das Werkstück erfolgt.The present invention was therefore based on the object of this Disadvantage to be avoided and a threaded nut of the kind mentioned at the beginning create a uniform force @n @@@@ ung i @ the workpiece.
Dies wird erfindungsgemäß dadurch erreicht, daß die Höhe des Bundes nicht größer als die Wandstärke des Bleches oder der Platte ist.This is achieved according to the invention in that the height of the federal government is not greater than the wall thickness of the sheet or plate.
Eine besonders günstige @efestigung der Gewindemutter wird erreicht, wenn bei der V@rformung des Bundes durch, einel; Stauchvorgang ein stumpfer Kegelwinkel von vorzugsweise über 100° gebildet wird, und wenn der Randbereich des Loches im Blecil oder der Platte während des Stauchvorganges durch den Bund derart verformt wird, daß er etwa den gleichen Kegelwinkel bildet.A particularly favorable fastening of the threaded nut is achieved if in the deformation of the covenant by, einel; Upsetting process an obtuse cone angle is formed by preferably over 100 °, and if the edge region of the hole in the Blecil or the plate deformed in this way by the collar during the upsetting process becomes that it forms approximately the same cone angle.
Nach einer besonders bevorzugten Ausführungsform der Erfindung ist vorgesehen, daß der ,und nach dem Stauchvorgaug nicht über die Fläche des Bleches oder der Platte vorragt.According to a particularly preferred embodiment of the invention provided that the, and after the Stauchvorgaug not over the surface of the sheet or the plate protrudes.
Dabei ist es besonders vorteilhaft zur Schaffung einer möglichst großen Anlagefläche, wenn die Unterseite des Bundes mit der Fläche des Blecljes oder der Platte in einer Ebene liegt.It is particularly advantageous to create the largest possible Contact surface if the underside of the collar with the surface of the Blecljes or the Plate lies in one plane.
Weitere vorteilhafte Ausfährungsformen der Erfindung sind den übrigen patentansprüchen zu Der Gegenstand der Erfindung soll im folgenden anhand von in der Zeichnung dargestellten Ausführungsbeispielen näher erläutert werden. In der Zeichnung zeigen Fig. 1 eine Seitenansicht einer erfindungsge mäßen Mutter mit Zwölfkant-Bund, Fig. 2 eine Draufsicht auf diese Mutter, Fig. 3 einen Schnitt nach der Linie III-III in Fig. 2, und Fig. 4 einen Schnitt durch eine Platte mit zwei daran befestigten Muttern.Further advantageous embodiments of the invention are the rest Claims to The subject of the invention is to be used in the following with reference to in Embodiments shown in the drawing are explained in more detail. In the Drawing show Fig. 1 a side view of a erfindungsge MAESSEN nut with twelve-point collar, Fig. 2 is a plan view of this nut, 3 shows a section according to the line III-III in Fig. 2, and Fig. 4 shows a section through a plate with two nuts attached to it.
Die in der Zeichnung dargestellte Gewindemutter 1 läuft auf einer Seite in einen hülsenförmigen und ? aus, der im dargestellten Ausführungsbeispiel an seinem Umfang die Form eines Zwölfkants aufweist und dessen Höhe a nicht größer ist als die Wandstärke einer Platte 3, in die die Gewindemutter 1 eingesetzt werden soll. Durch die Ausbildung des Bundes 2 als Zwölfkant wird die fertig montierte Gewindemutter gegen Verdrehung gesichert. Die Montage der Gewindemutter 1 erfolge derart, daß diese in ein entsprechend geformtes - hier also auch zwölfkantiges - Loch einer Platte 3 eingesetzt wird, wonach durch ein geeignetes Werkzeug der Bund 2 und der augrenzende Bereich der Platte 3 so verformt werden, daß ein stumpfer Winkelα gebildet wird und die Unterseite des verformten Bundes 2 anschließend nicht über die Unterseite der Platte vorragt, sondern mit dieser bsindig abschließt. Dadurch wird keine Kerbwirkung bzw. ringförmige Flöchenpressung beim anschließenden Susammenbau verursacht.The nut 1 shown in the drawing runs on a Side in a sleeve-shaped and? from that in the illustrated embodiment has the shape of a twelve-point on its circumference and its height a is not greater is than the wall thickness of a plate 3 into which the nut 1 are inserted target. By training the federal 2 as a twelve-point, the fully assembled Threaded nut secured against rotation. The assembly of the threaded nut 1 takes place in such a way that this is transformed into a correspondingly shaped - here also twelve-sided - Hole of a plate 3 is used, after which a suitable tool of the collar 2 and the border area of the plate 3 are deformed so that a blunt Winkelα is formed and the bottom of the deformed collar 2 then does not protrude beyond the underside of the plate, but is flush with it. As a result, there is no notch effect or ring-shaped surface pressure during the subsequent Assembly caused.
Beim Stauchvorgang ergibt sich fijr das daß c (Fig.4) ein Wert von ungefähr 2a. Das Maß b ergibt sich durch den siumpfen Kegelwinkel, und die Anpreßkraft der Gewindemutter am Werkstück wird kleiner gehalten, weil das Maß a kleiner ist als b.The upsetting process results in that c (FIG. 4) has a value of about 2a. The dimension b results from the low cone angle and the contact pressure the threaded nut on the workpiece is kept smaller because the dimension a is smaller as B.
Durch die ziemlich breite Kegelmantelfläche 4 - etwa 2b -, die sich nach dem Stauchvorgang bildet, wird es erleichtert, den Schraubbolzen einzuführen und somit die Mikreverkapselung nicht zu beschädigen. Hiermit bleibt das Drehmoment in der Schraube erhalten.Due to the fairly wide conical surface 4 - about 2b -, which forms after the upsetting process, it is easier to insert the screw bolt and thus not to damage the micro-encapsulation. This leaves the torque received in the screw.
