Description
Blechmutter Sheet metal nut
Die Erfindung betrifft eine Blechmutter mit je einem aus übereinander angeordneten Blechen um je eine etwa kreisförmige Aussparung kegelmantelförmig aufgebogenem Rand mit in einer Schraubenlinie verlaufender Begrenzungskante.The invention relates to a sheet metal nut with one on top of the other arranged metal sheets around an approximately circular recess bent upward in the shape of a cone Edge with limiting edge running in a helical line.
Muttern dieser Art, wie auch als Käfigmuttern ausgebildete Muttern bestehen meist aus mehreren Teilen und weisen auch einen Aufbau auf, der zu ihrer Herstellung teure Werkzeuge erfordert.Nuts of this type, as well as nuts designed as cage nuts usually consist of several parts and also have a structure that corresponds to their Manufacturing requires expensive tools.
Es liegt der Erfindung daher die Aufgabe zugrunde, die Herstellung solcher Massenartikel zu vereinfachen und damit zu verbilligen.It is therefore the object of the invention to manufacture to simplify such mass-produced articles and thus to make them cheaper.
Der Erfindung liegt die weitere Aufgabe zugrunde, die Blechiautter so auszubilden, daß ein sicherer Halt der Schraube in der Mutter auch ohne die Verwendung eines Sicherungsringes gewährleistet ist.The invention is based on the further object of the sheet metal nut to train so that a secure hold of the screw in the nut even without the use a locking ring is guaranteed.
Die an erster Stelle genannte Aufgabe wird gemäß der Erfindung dadurch gelöst, daß die Blechmutter als einstückige mäanderartig gefaltete Platine ausgebildet ist, in der die beiden mit ihren Rändern die Gewindegänge bildenden, im wesentlichen kreisförmigen Aussparungen gleicliachsig anyeordnet sind, und daß das freie, eine kreisförmige Ausnehmung aufweisende Ende der Platine dem Schraubenkopf als Widerlager dient.The object mentioned in the first place is thereby achieved according to the invention solved that the sheet metal nut is designed as a one-piece meander-like folded plate is, in which the two with their edges forming the threads, essentially circular recesses are arranged equiaxially, and that the free, one circular recess having end of the board the screw head as an abutment serves.
Die an zweiter Stelle genannte Aufgabewird gemäß der Erfindung dadurch gelöst, daß die Begrenzungskanten der aufgebogenen Ränder der im wesentlichen kreisförmigen Aussparungen eine größere Steigung aufweisen als es der Schraubennorm entspricht, und daß vorzugsweise an einem der beiden die Aussparungen aufweisenden Platinenabschnitte mindestens eine in Richtung auf den anderen Platinenabschnitt weisende Sicke ausgebildet ist.The second object is thereby achieved according to the invention solved that the boundary edges of the upturned edges of the substantially circular Recesses have a greater gradient than the screw standard, and that preferably on one of the two plate sections having the recesses formed at least one bead pointing in the direction of the other plate section is.
Zur Erzielung eines möglichst großen Sicherungseffektes besteht die erfindungsgemäße Blechmutter vorteilhafter weise aus federelastischem Werkstoff.In order to achieve the greatest possible safety effect, there is the Sheet metal nut according to the invention advantageously made of resilient material.
In der Zeichnuny ist ein Ausführungsbeispiel der erfindungsgemäßen Blechmutter in schematischer Weise dargestellt. Es zeigen Fig. 1 eine Draufsicht auf die vorgeformte, noch nicht gefaltete Platine; Fig. 2 eine Seitenansicht der Blechmutter in ihrer endgültigen Gestalt; Fig. 3 eine weitere Seitenansicht der Blechmutter in Blickrichtung auf die linke Seite der Fig. 2.In the drawing is an embodiment of the invention Sheet metal nut shown in a schematic manner. 1 shows a plan view onto the preformed, not yet folded board; Fig. 2 is a side view of the Tin nut in its final form; Fig. 3 is a further side view of the Sheet metal nut in the direction of view of the left side of FIG. 2.
Die Platine 1 weist eine kreisförmige Ausnehmung 2 sowie zwei im wesentlichen kreisförmige Aussparungen 3 und 4 sowie zwei Sicken 5 und 5r auf. Die Ränder der beiden im wesentlichen kreisförmigen Aussparungen weisen einen radialen Einschnitt 31 bzw. 41 auf, so daß die beiden die Aussparungen 3 und 4 umgebenden Ränder in Gestalt eines Kegelmantels (32,33 bzw. 42,43) aus der Platinenebene herauagedrückt werden können und die Begrenzungs-]canten der Ränder eine Schraubenlinie bilden. Da diese Begrenzungskanten eine größere Steigung aufweisen als es der jeweiligen Schraubennorm entspricht, besteht die Gefahr, daß der obere freie, die Aussparung 4 aufnehmende Abschnitt der Platine gegen den mittleren Abschnitt heranyedrückt wird. Um dies zu verhindern und die kegelmantelförmigen Ränder unter Spannung zu halten, sind die Sicken 5 und 5' vorgesehen. Der untere, das andere freie D'nde der Platine bildende Abschnitt nimmt in der kreisförmigen Aussparung 2 die Schraube auf und dient dem Schraubenkopf als Widerlager.The board 1 has a circular recess 2 and two essentially circular recesses 3 and 4 and two beads 5 and 5r. The edges of the both essentially circular recesses have a radial cut 31 and 41, so that the two edges surrounding the recesses 3 and 4 in Shape of a conical shell (32,33 or 42,43) pressed out of the plane of the plate can be and the delimiting] edges of the edges form a helix. Since these boundary edges have a greater slope than the respective one Screw standard, there is a risk that the upper free, the recess 4 receiving section of the board pressed against the middle section will. To prevent this and the cone-shaped Margins To keep it under tension, the beads 5 and 5 'are provided. The lower one, the other The section forming the free end of the board takes place in the circular recess 2 the screw and serves as an abutment for the screw head.
