Abstract
Die Erfindung betrifft ein Fügeelement, insbesondere eine loch- und gewindeformende Schraube, zum Direktverschrauben von Bauteilen (11), mit einem Kopf (12) und einem sich vom Kopf (12) aus erstreckenden Schaft (14), wobei der Schaft (14) einen selbstformenden Gewindeabschnitt (18) und einen Lochformungsabschnitt (20) zum Fließlochformen aufweist, wobei der Gewindeabschnitt (18) zwischen dem Kopf (12) und dem Lochformungsabschnitt (20) angeordnet ist. Um den Einsatzbereich zu vergrößern wird vorgeschlagen, dass ein Außendurchmesser (46) des Lochformungsabschnitts (20) größer ist als ein Kerndurchmesser (34) des Gewindeabschnitts (18).The invention relates to a joining element, in particular a hole- and thread-forming screw, for direct screwing of components (11), with a head (12) and a shaft (14) extending from the head (12), wherein the shaft (14) has a self-tapping threaded portion (18) and a hole-forming portion (20) for flow-hole forming, wherein the threaded portion (18) between the head (12) and the hole-forming portion (20) is arranged. To increase the range of use, it is proposed that an outer diameter (46) of the hole forming portion (20) is larger than a core diameter (34) of the threaded portion (18).
Description
Die Erfindung betrifft ein Fügeelement, insbesondere eine loch- und gewindeformende Schraube, zum Direktverschrauben von Bauteilen, mit einem Kopf und einem sich vom Kopf aus erstreckenden Schaft, wobei der Schaft einen selbstformenden Gewindeabschnitt und einen Lochformungsabschnitt zum Fließlochformen aufweist, wobei der Gewindeabschnitt zwischen dem Kopf und dem Lochformungsabschnitt angeordnet ist.The invention relates to a joining element, in particular a hole- and thread-forming screw, for directly screwing components, with a head and a head extending from the top, the shaft having a self-forming threaded portion and a hole forming portion for flow-hole forming, wherein the threaded portion between the head and the hole forming portion is arranged.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde eine verbesserte oder zumindest andere Ausführungsform eines Fügeelements bereitzustellen, die sich insbesondere durch einen größeren Anwendungsbereich auszeichnet.The present invention has for its object to provide an improved or at least other embodiment of a joining element, which is characterized in particular by a wider range of applications.
Die Erfindung beruht auf dem allgemeinen Gedanken, dass wenn das geformte Fließloch größer als bisher ausgestaltet wird, sich somit das Drehmoment, das zum Einschrauben des Gewindeabschnitts in die Fließlöcher aufgewendet werden muss, reduzieren lässt. Erfindungsgemäß ist dementsprechend vorgesehen, dass ein Außendurchmesser des Lochformungsabschnitts größer ist als ein Kerndurchmesser des Gewindeabschnitts. Da nun durch den Lochformungsabschnitt ein Loch erzeugt wird, dessen Durchmesser größer ist als der Kerndurchmesser, reduziert sich eine Furchtiefe des selbstformenden Gewindeabschnitts in den zu verbindenden Bauteilen. Dadurch reduziert sich auch das aufzubringende Drehmoment beim Einschrauben des Fügeelements in die beiden Bauteile. Somit können Bauteile verbunden werden, die eine höhere Festigkeit aufweisen als bisher üblich oder eine größere Dicke aufweisen als bisher üblich.The invention is based on the general idea that, when the molded flow hole is made larger than heretofore, the torque which has to be expended for screwing the threaded portion into the flow holes can be reduced. According to the invention, it is accordingly provided that an outer diameter of the hole-forming section is greater than a core diameter of the threaded section. Now, since a hole whose diameter is larger than the core diameter is formed by the hole forming portion, a depth of the self-forming threaded portion in the components to be joined is reduced. This also reduces the applied torque when screwing the joining element in the two components. Thus, components can be connected, which have a higher strength than previously usual or have a greater thickness than previously usual.
In der Beschreibung und den beigefügten Ansprüchen wird unter einem Kerndurchmesser des Gewindeabschnitts der Kerndurchmesser des Gewindes an dem Gewindeabschnitt verstanden.In the specification and the appended claims, a core diameter of the threaded portion is understood to mean the core diameter of the thread on the threaded portion.
Eine günstige Möglichkeit sieht vor, dass der Außendurchmesser des Lochformungsabschnitts kleiner als ein Nenndurchmesser des Gewindeabschnitts ist. Da der Lochformungsabschnitt im Wesentlichen den Durchmesser des gebildeten Fließloches in den Bauteilen bestimmt, kann somit verhindert werden, dass der selbstformende Gewindeabschnitt nicht mehr in die Bauteile eingreifen kann, um ein entsprechendes Gewinde in den Fließlöchern zu formen.A favorable possibility provides that the outer diameter of the hole-forming section is smaller than a nominal diameter of the threaded section. Thus, since the hole forming portion substantially determines the diameter of the formed flow hole in the components, it can be prevented that the self-forming threaded portion can not intervene in the components to form a corresponding thread in the flow holes.
In der Beschreibung und den beigefügten Ansprüchen wird unter einem Nenndurchmesser des Gewindeabschnitts der Nenndurchmesser des Gewindes an dem Gewindeabschnitt verstanden.In the specification and the appended claims, a nominal diameter of the threaded portion is understood to mean the nominal diameter of the thread on the threaded portion.
Eine weitere günstige Möglichkeit sieht vor, dass eine Gewindetiefe einer halben Differenz zwischen Nenndurchmesser und Kerndurchmesser des Gewindeabschnitts entspricht und dass der Außendurchmesser des Lochformungsabschnitts um das 0,6- bis 1,4-fache der Gewindetiefe an einem Verbindungsabschnitt der Gewindeabschnitts größer ist als der Kerndurchmesser des Gewindeabschnitts, vorzugsweise um das 0,8- bis 1,2-fache. Es hat sich gezeigt, dass ein Außendurchmesser des Lochformungsabschnitts in diesem Bereich besonders günstig für die Reduzierung der Einschraubmomente ist, wobei gleichzeitig die daraus entstehende Schraubverbindung weiterhin eine ausreichende Stabilität aufweist.A further favorable possibility provides that a thread depth corresponds to half the difference between nominal diameter and core diameter of the threaded section and that the outer diameter of the hole forming section is 0.6 to 1.4 times the thread depth at a connecting section of the threaded section greater than the core diameter the threaded portion, preferably by 0.8 to 1.2 times. It has been found that an outer diameter of the hole-forming section in this area is particularly favorable for reducing the screw-in moments, while at the same time the resulting screw connection still has sufficient stability.
Weitere wichtige Merkmale und Vorteile der Erfindung ergeben sich aus den Unteransprüchen, aus den Zeichnungen und aus der zugehörigen Figurenbeschreibung anhand der Zeichnungen.Other important features and advantages of the invention will become apparent from the dependent claims, from the drawings and from the associated figure description with reference to the drawings.
Es versteht sich, dass die vorstehend genannten und die nachstehend noch zu erläuternden Merkmale nicht nur in der jeweils angegebenen Kombination, sondern auch in anderen Kombinationen oder in Alleinstellung verwendbar sind, ohne den Rahmen der vorliegenden Erfindung zu verlassen.It is understood that the features mentioned above and those yet to be explained below can be used not only in the particular combination given, but also in other combinations or in isolation, without departing from the scope of the present invention.
