Title of Invention: Verfahren und Vorrichtung zum Setzen von spanlos selbstlochformenden Verbindungselementen Technisches Gebiet  Title of Invention: Method and apparatus for setting non-cutting self-piercing fasteners. Technical field
[0001] Die vorliegende Erfindung betrifft ein Verfahren zum Setzen von spanlos  The present invention relates to a method for setting without cutting
selbstlochformenden Verbindungselementen wie Schrauben oder Blindnieten in ein oder mehrere Bleche, wobei das oder die Bleche kurz vor Beginn des Setzvorganges mittels elektrischer Energie erhitzt werden. Des weiteren betrifft die vorliegende Erfindung eine entsprechende Vorrichtung zum Setzen eines spanlos  Selbstlochformenden fasteners such as screws or blind rivets in one or more sheets, the sheet or sheets are heated shortly before the beginning of the setting process by means of electrical energy. Furthermore, the present invention relates to a corresponding device for setting a non-cutting
selbstlochformenden Verbindungselementes in ein oder mehrere Bleche.  Selbstlochformenden connecting element in one or more sheets.
[0002] Spanlos selbstlochformende Verbindungselemente, die auch als Fließloch- Bohrschrauben oder -Verbindungselemente bezeichnet werden, werden in der Industrie zunehmend bevorzugt eingesetzt, da bei ihrer Verwendung auf Vorbohren und Gewindeschneiden verzichtet werden kann und bei der Verarbeitung keine Späne anfallen.  Spanlos self-perforating fasteners, which are also referred to as Fließloch- drilling screws or -Verbindungselemente, are increasingly preferred in the industry, since their use can be dispensed with pre-drilling and tapping and incurred during processing no chips.
Stand der Technik  State of the art
[0003] Bisher konnten diese Verbindungselemente jedoch lediglich in Verbindung mit normalen Stahl- und Aluminiumblechen verwendet werden. Eine Verwendung in hochfesten Stahlblechen ohne Vorbohren schied aus, da die durch das  So far, however, these fasteners could only be used in conjunction with normal steel and aluminum sheets. A use in high-strength steel sheets without pre-drilling differed, as by the
Verbindungselement übertragbare Wärmeenergie nicht ausreicht, um ein hochfestes Stahlblech entsprechend zu erweichen.  Connecting element transferable heat energy is insufficient to soften a high-strength steel sheet accordingly.
[0004] Zur Lösung dieses Problems hat der hierzu nächstgelegene Stand der Technik, die DE 196 34 417 AI, bereits vorgeschlagen, das Material des Bleches in das  To solve this problem of this closest prior art, DE 196 34 417 Al, has already been proposed, the material of the sheet in the
Verbindungselement gesetzt werden soll, durch elektrische  Connecting element should be set by electrical
[0005] Energie in Form eines Lichtbogens zwischen einem der Lochformung dienenden Werkzeug und dem Blech zu erhitzen.  To heat energy in the form of an arc between a die forming tool and the sheet.
[0006] Dieser Vorschlag hat aber erhebliche Nachteile, da die Stromdichte in der Bohrspitze des Lochformwerkzeugs stets wesentlich höher ist, als in dem großflächigen Blech. Dadurch erhitzt sich die Bohrspitze stärker als das Blech und die Bohrspitze wird stärker erweicht als das Blech, was im Sinne der hier vorliegenden Aufgabenstellung klar kontraproduktiv ist. Des weiteren kann die Spitze des Lochformwerkzeugs, deren Form für eine korrekte Lochformung von außerordentlich großer Bedeutung ist, durch den Lichtbogen und den damit verbundenen Kontaktabbrand beschädigt oder verformt werden, wodurch wiederum das Formen des Loches erheblich erschwert werden kann. However, this proposal has considerable disadvantages, since the current density in the drill bit of the hole forming tool is always substantially higher than in the large-area sheet metal. As a result, the drill bit heats up more than the sheet and the drill bit is softened more than the sheet, which is clearly counterproductive in terms of the present task. Further, the tip of the hole forming tool, the shape of which is of paramount importance for correct hole formation, may be damaged or deformed by the arc and the concomitant contact erosion, which, in turn, can significantly complicate the forming of the hole.
Darstellung der Erfindung [0007] Es ist daher Aufgabe der vorliegenden Erfindung, das Setzen von spanlos selbstlochformenden Verbindungselementen in hochfeste Stahlbleche unmittelbar während des Erhitzens des Bleches und ohne den Einsatz eines separaten Presentation of the invention It is therefore an object of the present invention, the setting of non-cutting self-perforating fasteners in high-strength steel sheets directly during heating of the sheet and without the use of a separate
Lochformwerkzeuges zu ermöglichen.  To allow hole forming tool.
[0008] Erfindungsgemäß wird diese Aufgabe durch ein Verfahren gelöst, bei dem die According to the invention this object is achieved by a method in which the
Erhitzung durch eine Induktionsspule erfolgt, die in der Nähe einer Stelle auf dem oder den Blechen angeordnet wird, an der das Verbindungselement gesetzt wird.  Heating is performed by an induction coil, which is placed near a location on the sheet or plates on which the connecting element is placed.
[0009] Ebenso kann die vorliegende Aufgabe erfindungsgemäß durch eine Vorrichtung zum Setzen eines spanlos selbstlochformenden Verbindungselementes in ein oder mehrere Bleche gelöst werden, die mit einer Induktionsspule versehen ist, die zumindest vor und/oder während des Setzvorganges in der Nähe der Stelle auf dem oder den Blechen angeordnet ist, an der das Verbindungselement gesetzt werden soll.  Likewise, the present object can be achieved by a device for setting a non-cutting self-hole connecting element in one or more sheets, which is provided with an induction coil, at least before and / or during the setting process in the vicinity of the point on or the sheets is arranged, on which the connecting element is to be set.
[0010] Bevorzugt ist es dabei, wenn die Induktionsspule konzentrisch zu der Stelle auf dem oder den Blechen angeordnet wird, an der das Verbindungselement gesetzt werden soll.  It is preferred in this case if the induction coil is arranged concentrically to the location on the sheet or plates on which the connecting element is to be set.
[0011] Besonders bevorzugt ist es, wenn die Induktionsspule eine zentrale Öffnung aufweist und während des Setzvorganges oberhalb des oder Bleche verbleibt und das  It is particularly preferred if the induction coil has a central opening and remains during the setting process above the or sheets and the
Verbindungselement durch diese zentrale Öffnung der Induktionsspule hindurch gesetzt wird.  Connecting element is set through this central opening of the induction coil.
