BefestigungselementFastener
Die Erfindung betrifft ein Befestigungselement zum Aufschweißen auf gelochtes oder ungelochtes Blechmaterial mittels Lichtbogen-Bolzenschweißen mit Hubzündung oder Kurzzeithubzündung. The invention relates to a fastening element for welding onto perforated or unperforated sheet material by means of arc stud welding with drawn arc ignition or short-cycle drawn arc ignition.
Derartige Befestigungselemente weisen im allgemeinen die Form eines Hohlkörpers mit Innengewinde, beispielsweise eines kreiszylinderförmigen Hohlkörpers mit Innengewinde oder auch die Form einer Schweißmutter auf.Such fastening elements generally have the shape of a hollow body with an internal thread, for example a circular-cylindrical hollow body with an internal thread or the shape of a weld nut.
Um die Zentrierung solcher Befestigungselemente bezüglich eines Lochs beispielsweise in gelochtem Blechmaterial zu erleichtern, ist es bekannt, ein Ende der Befestigungselemente am äußeren Randbereich mit einer konischen Anfasung zu verse-5 hen. Bezogen auf die Außenfläche, beispielsweise eines kreis-In order to facilitate the centering of such fastening elements with respect to a hole, for example in perforated sheet metal material, it is known to provide one end of the fastening elements with a conical chamfer on the outer edge area. In relation to the outer surface, for example of a circular
• ····
zylinderförmigen Hohlkörpers liegt der Winkel einer solchen konischen Anfasung vorzugsweise im Bereich von 2 0 bis 3 0°.For a cylindrical hollow body, the angle of such a conical chamfer is preferably in the range of 2 0 to 3 0°.
Beim Verschweißen von Befestigungselementen, die an einem Ende angefast sind, muß vom Bedienungspersonal immer darauf geachtet werden, daß das Befestigungselement in den Elementhalter einer Schweißpistole bzw. eines Schweißkopfes so eingeführt wird, daß das angefaste Ende des Befestigungselements aus dem Elementenhalter vorsteht.When welding fasteners that are chamfered at one end, the operator must always ensure that the fastener is inserted into the element holder of a welding gun or welding head in such a way that the chamfered end of the fastener protrudes from the element holder.
Um die Möglichkeit auszuschließen, daß ein Befestigungselement mit dem Ende aufgeschweißt wird, das keine Anfasung aufweist, ist gemäß der Erfindung ein Befestigungselement geschaffen, bei welchem beide Enden unter einem spitzen Winkel bezüglich der zu den beiden Enden senkrecht verlaufenden Außenfläche konisch angefast sind. Hierbei liegt der spitze Winkel der konischen Anfasung vorzugsweise in einem Bereich von 2 0° bis 60° bezüglich der senkrecht zu den beiden Endflächen verlaufenden Außenfläche.In order to eliminate the possibility of a fastener being welded to the end that does not have a chamfer, the invention provides a fastener in which both ends are conically chamfered at an acute angle with respect to the outer surface running perpendicular to the two ends. The acute angle of the conical chamfer is preferably in a range of 20° to 60° with respect to the outer surface running perpendicular to the two end surfaces.
Solche an beiden Enden angefaste Befestigungselemente können somit problemlos von Hand und insbesondere automatisch einer Schweißvorrichtung zugeführt werden.Such fastening elements, which are chamfered at both ends, can therefore be easily fed into a welding device by hand and, in particular, automatically.
Eine bevorzugte Ausfuhrungsform der Erfindung wird nunmehr anhand der anliegenden Zeichnung beschrieben, welche stark vergrößert in einer schematischen, unmaßstäblichen Darstellung ein Befestigungselement gemäß der Erfindung zeigt.A preferred embodiment of the invention will now be described with reference to the accompanying drawing, which shows a fastening element according to the invention in a greatly enlarged schematic representation, not to scale.
In der Zeichnung ist ein Befestigungselement in Form eines kreiszylindrischen Hohlkörpers 1, beispielsweise einer Schweißmutter im Schnitt dargestellt. Das Befestigungselement weist ein durchgehendes Innengewinde 11 auf, das symmetrisch zu einer strichpunktiert wiedergegebenen Achse A ist. Zwei Endflächen 12-l und 122 verlaufen senkrecht zu der Mittenachse A, während eine Außenfläche 10 des Elements 1 parallel zu der Mittenachse A ausgerichtet ist.The drawing shows a fastening element in the form of a circular cylindrical hollow body 1, for example a weld nut, in section. The fastening element has a continuous internal thread 11 that is symmetrical to an axis A shown in dash-dot lines. Two end surfaces 12-1 and 122 run perpendicular to the central axis A, while an outer surface 10 of the element 1 is aligned parallel to the central axis A.

The conical chamfers 13 of the two end surfaces 12-^ and 122 can, if necessary, also have different acute angles. *****
