Description
Die vorliegende Erfindung betrifft einen Stanzniet für hochfeste Bleche sowie eine Nietverbindung mit einem derartigen Stanzniet.The present invention relates to a punch rivet for high-strength sheets and a rivet connection with such Rivet.
Das Stanznieten zum Fügen von zwei oder mehr Blechen erfreut sich zunehmender Beliebtheit, beispielsweise in der Kraftfahrzeugtechnik. Als Halbhohlniet ausgebildete Stanzniete bestehen üblicherweise aus einem Kopf und einem Hohlschaft, der eine zylindrische Außenfläche und eine zylindrische Innenfläche hat.The punch riveting for joining two or more sheets are becoming increasingly popular, for example in automotive engineering. Punch rivets designed as semi-tubular rivets usually exist from a head and a hollow shaft, which has a cylindrical outer surface and a cylindrical inner surface Has.
Aus der
Es hat sich gezeigt, dass beim Stanznieten hochfester Bleche Schwierigkeiten auftreten können. So sind herkömmliche Stanzniete häufig nicht in der Lage, die beim Stanznieten hochfester Bleche auftretenden hohen Fügekräfte aufzunehmen. Die Qualität der Fügeverbindung lässt daher häufig zu wünschen übrig. Im Extremfall kann es zu Rissen, Brüchen oder Aufstauchen sowohl beim Durchstanzen des oberen Bleches wie auch beim Aufspreizen des unteren Bleches kommen.It has been shown that punch riveting is stronger Sheet metal difficulties can occur. So are conventional Punch rivets often unable to handle the high-strength sheet metal when punch riveting absorb high joining forces. The quality of the Retaining compound therefore leaves frequently to be desired. in the In extreme cases, there may be cracks, breaks or upsetting both when punching through the top sheet like also come when spreading the lower sheet.
Der vorliegenden Erfindung liegt die Aufgabe zugrunde, einen Stanzniet zu schaffen, der auch beim Fügen hochfester Bleche eine optimale Qualität der Nietverbindung gewährleistet.The present invention lies based on the task of creating a punch rivet that can also be used for Add high strength Sheets of optimal quality Rivet connection guaranteed.
Diese Aufgabe wird durch einen in Anspruch 1 definierten Stanzniet gelöst.This task is carried out by an in Claim 1 defined punch rivet solved.
Erfindungsgemäß hat der Hohlschaft eine Querschnittsfläche, die eine normierte Flächenpressung, bezogen auf 1 N, von weniger als 0,07 N/mm², vorzugsweise 0,063 N/mm² ergibt. Zweckmäßigerweise hat der Werkstoff des Stanznietes eine Zugfestigkeit von mehr als 1800 N/mm² und eine Härte von mehr als 550 HV 10.According to the invention, the hollow shaft has a cross-sectional area that a standardized surface pressure, based on 1 N, less than 0.07 N / mm², preferably 0.063 N / mm². Conveniently, the material of the punch rivet has a tensile strength of more than 1800 N / mm² and a hardship of more than 550 HV 10.
Aufgrund dieser Dimensionierung des Hohlschaftes und der bevorzugten Wahl des Werkstoffes ist der Stanzniet in der Lage, die beim Fügen hochfester Bleche erforderlichen Fügekräfte ohne Schädigung aufzunehmen.Because of this dimensioning of the The punch rivet is the hollow shaft and the preferred choice of material able to when joining high-strength sheet metal required to absorb joining forces without damage.
Wichtig in diesem Zusammenhang ist die radiale Lage der ringförmigen Nietschneide. Liegt die ringförmige Nietschneide, radial gesehen, zu weit innen, so kann sich der Stanzniet nicht in der gewünschten Weise aufspreizen. Liegt die ringförmige Schneide zu weit außen, so kann es aufgrund eines zu großen radialen Versatzes zwischen dem mittleren Durchmesser des Hohlschaftes und der Einleitung der Fügekraft in die zu fügenden Werkstücke zu überhöhten Biegebeanspruchungen des Stanznietes kommen.It is important in this context the radial position of the annular Nietschneide. The ring lies Rivet cutter, seen radially, too far inside, so the punch rivet can not in the one you want Spread wise. If the ring-shaped cutting edge is too far out, so it may be too big because of one radial offset between the average diameter of the hollow shaft and the initiation of joining force into those to be joined workpieces to excessive bending stress of the punch rivet.
In weiterer Ausgestaltung der Erfindung ist daher vorgesehen, dass die ringförmige Nietschneide gegenüber dem mittleren Durchmesser des Hohlschaftes geringfügig radial nach außen versetzt ist, um eine versatzarme Einleitung der Fügekraft in die zu nietenden Werkstücke beim Nietvorgang zu gewährleisten. Vorzugsweise ist der Durchmesser der ringförmigen Nietschneide um einen Betrag zwischen 0 und 6% des mittleren Durchmessers des Hohlschaftes größer als dieser mittlere Durchmesser. Hierdurch wird eine Ü-berlastung im Umfang des Nietfußes durch Dehnung aufgrund einer Aufspreizung des Hohlschaftes zum Nietfuß hin eingeschränkt, insbesondere beim Durchstanzen der ersten Lage der Fügeverbindung.In a further embodiment of the invention it is therefore provided that the ring-shaped rivet cutter opposite the average diameter of the hollow shaft slightly offset radially outwards is a low-offset introduction of the joining force into the riveted workpieces to ensure during the riveting process. The diameter of the ring-shaped rivet cutter is preferably one Amount between 0 and 6% of the average diameter of the hollow shaft larger than this average diameter. This will overload the scope of the rivet foot restricted by stretching due to an expansion of the hollow shaft towards the rivet base, in particular when punching through the first layer of the joint.
Stanzniete werden üblicherweise aus Drahtstücken durch Kaltumformen auf Mehrstufenpressen hergestellt. Herkömmlicherweise kann zumindest in der letzten Stufe des Umformvorganges das Material des Stanznietes entlang eines Pressstempels in axialer Richtung frei fließen. Dies führt dazu, dass die Geometrie des Nietfußes und insbesondere der ringförmigen Nietschneide nicht genau definiert ist, insbesondere nicht homogen ist und beispielsweise Fehlstellen aufweist.Punch rivets are commonly used from pieces of wire produced by cold forming on multi-stage presses. traditionally, can at least in the last stage of the forming process the material of the Punch rivets along a press ram free in the axial direction flow. this leads to to the fact that the geometry of the rivet foot and in particular the ring-shaped rivet cutter is not is precisely defined, in particular is not homogeneous and, for example, imperfections having.
In weiterer Ausgestaltung der Erfindung ist daher vorgesehen, dass die ringförmige Ringschneide durch Umformen mittels eines als Negativ der Nietschneide ausgebildeten Werkzeuges formgenau hergestellt ist. Es entsteht somit ein Nietfuß, der eine präzise, reproduzierbare, homogene Form hat, die abgesehen von unvermeidlichen Fertigungstoleranzen, für alle Niete die gleiche ist. Hierdurch werden beim Nietvorgang auftretende Spannungsspitzen am Stanzniet minimiert. Ferner lässt sich die Lage der ringförmigen Nietschneide mit hoher Genauigkeit festlegen, um die beabsichtigte versatzarme Einleitung der Fügekraft in die zu fügenden Werkstücke sicherzustellen.In a further embodiment of the invention it is therefore provided that the ring-shaped ring cutting edge by forming by means of a tool designed as a negative of the rivet cutter is manufactured to the exact shape. This creates a rivet foot that has a precise, reproducible, has a homogeneous shape that, apart from inevitable manufacturing tolerances, for all Rivets is the same. This will result in the riveting process Stress peaks on the punch rivet minimized. Furthermore, the location of the annular Set rivet cutter with high accuracy to the intended Low-offset introduction of the joining force into those to be joined workpieces sure.
Der erfindungsgemäß ausgebildete Stanzniet ist besonders geeignet für eine Nietverbindung von hochfesten Blechen, deren Zugfestigkeit größer als 400 MPa ist. Die Erfindung umfasst daher auch derartige Nietverbindungen.The punch rivet designed according to the invention is particularly suitable for a riveted joint of high-strength sheets, their tensile strength larger than Is 400 MPa. The invention therefore also includes such riveted joints.
Weitere vorteilhafte Ausgestaltungen der Erfindung gehen aus den Unteransprüchen hervor.Further advantageous configurations the invention emerge from the subclaims.
Anhand der einzigen Figur, die einen Längsschnitt durch einen Stanzniet zeigt, wird ein bevorzugtes Ausführungsbeispiel der Erfindung näher erläutert.Based on the single figure, the one longitudinal section through a punch rivet is a preferred embodiment the invention closer explained.
