Abstract
Description
Die Erfindung bezieht sich auf eine Vorrichtung zur Bestimmung von Niederhaltekräften nach dem Oberbegriff des Patentanspruches 1.The invention relates to a device for determining hold-down forces according to the preamble of
Das Herstellen von Fügeverbindungen unter Verwendung eines Stempels und mindestens eines der zu fügenden Bauteile beaufschlagenden Niederhalters ist bekannt, beispielsweise in Gestalt des Nietsetzens oder des Durchsetzfügeverfahrens (Clinchen), wobei beide genannte Verfahren in der Automobiltechnik, nämlich im Karosseriebau, vielfältige Anwendungen finden. Während beim Durchsetzfügen der Stempel unmittelbar die zu fügenden Bauteile beaufschlagt, sorgt er beim Stanznieten für das Eindringen eines die Fügeverbindung herstellenden Fügeelementes in die Bauteile.The production of joint connections using a stamp and at least one of the components to be joined acting downholder is known, for example in the form of Nietsetzens or the clinching process, both said methods in automotive engineering, namely in the body shop, find a variety of applications. While the punch acts directly on the components to be joined during the clinching, it provides the punch riveting for the penetration of a joining compound producing joining element in the components.
Verschiedene Verfahrensweisen und Vorrichtungen zum Verbinden von Werkstoffen durch Stanznieten sind beispielsweise in den Dokumenten
Da also das Arbeitsergebnis beim Fügen durch Umformen in fast allen Fällen stark von der Niederhalterkraft abhängig ist, muss diese sehr sorgfältig bestimmt und dann auch exakt gemessen werden können. Bei konventionellen Setzsystemen, wie die bereits erwähnten Stanznietzangen, wird der Stempelvorschub über einen elektromotorischen oder hydraulischen Antrieb gesteuert. Der Niederhalter bzw. die Niederhalterkraft wird dabei über eine mechanische Feder mit dem Stempelantrieb bzw. der Stempelkraft gekoppelt.Since, in most cases, the result of the joining process by reshaping is strongly dependent on the holding force, it must be able to be determined very carefully and then measured exactly. In conventional setting systems, such as the aforementioned punched rivet tongs, the punch feed is controlled by an electromotive or hydraulic drive. The hold-down or the hold-down force is coupled via a mechanical spring with the punch drive or the punch force.
Da Stempel und Niederhalter über den selben Antrieb verfahren werden, ist mit herkömmlichen Kraftmesseinrichtungen die Ermittlung der Niederhaltekraft ohne den Einfluss der Stempelkraft nicht möglich. Niederhaltekräfte können derzeit nur näherungsweise über eine Berechnung ermittelt werden. Alternativ wird die Niederhaltekraft durch den Ausbau des Fügestempels ermittelt. Die Kraftmessung kann in diesem Falle jedoch nur ohne Fügeelement erfolgen. Gleichermaßen ist bei Anlagen mit getrennten Antrieben für Stempel und Niederhalter eine Messung der Niederhaltekraft während des Setzprozesses (mit Fügeelement) nicht möglich.Since punches and hold-downs are moved by the same drive, the determination of the holding force without the influence of the punch force is not possible with conventional force measuring devices. Holding down forces can currently only be approximated through a calculation. Alternatively, the hold-down force is determined by removing the joining punch. The force measurement can be done in this case, however, only without joining element. Likewise, in systems with separate drives for punches and hold-downs, it is not possible to measure the hold-down force during the setting process (with joining element).

Aus
Von daher liegt der Erfindung die Aufgabe zugrunde, eine verbesserte Möglichkeit aufzuzeigen, um eine exakte Ermittlung der Niederhaltekraft bei der Herstellung einer Fügeverbindung von Bauteilen unter Verwendung eines Stempels und eines separaten Niederhalters durchführen zu können.It is therefore an object of the present invention to provide an improved possibility of being able to carry out an exact determination of the hold-down force in the production of a joining connection of components using a punch and a separate hold-down device.
Dies gelingt erfindungsgemäß mit einer Vorrichtung gemäß Patentanspruch 1. Vorteilhafte Ausgestaltungen und Weiterbildungen dieser Vorrichtung sind mit den weiteren Unteransprüchen beansprucht.This is achieved according to the invention with a device according to
Gemäß der erfindungsgemäßen Vorgehensweise wird die Messung der Niederhaltekraft durch die Entkopplung derselben von der Stempelkraft möglich. Damit ist ein aufwendiger Stempelausbau für die Messung der Niederhaltekraft bei konventionellen Anlagen mit nur einem Antrieb nicht mehr erforderlich. Bei Anlagen mit nur einem Antrieb und bei solchen mit getrennten Antrieben für Stempel und Niederhalter kann die Niederhaltekraftmessung nun auch beim Setzprozess mit Fügeelement erfolgen. Der Einfluss des Setzprozesses auf die Niederhaltekraft kann dadurch mitberücksichtigt werden. Durch die erfassten Messwerte können mit einem veränderten Niederhaltedruck bzw. einer neuen Federkennlinie die Prozessbedingungen optimiert werden.According to the procedure of the invention, the measurement of the hold-down force by decoupling the same of the punch force is possible. This eliminates the need for a complex stamp removal for measuring the hold-down force in conventional systems with only one drive. For systems with only one drive and those with separate drives for punches and hold-downs, hold-down force measurement can now also be performed during the setting process with the joining element. The influence of the setting process on the holding force can be taken into account. The acquired measured values can be used to optimize the process conditions with a modified hold-down pressure or a new spring characteristic.
