Abstract
Description
Das an sich bekannte Werkzeug ( z.B. Patente GB1523160A, US4283933A ) dient dazu, Werkstücke unterschiedlicher Größe in einem Universalgesenk ( Stempel und Matrize ) zu verpressen und dennoch mittels eines Ratschensperrmechanismus eine definierte Endstellung der Handhebel und damit eine definierte Krafteinwirkung auf das Werkstück sicherzustellen.The known tool (e.g. Patents GB1523160A, US4283933A) are used to make different workpieces Size in one Universal die (stamp and die) to be pressed and yet a defined end position by means of a ratchet locking mechanism the hand lever and thus a defined force on the workpiece sure.
In der Praxis ist die Verwendung solcher Werkzeuge vornehmlich für die Verpressung von sog. Aderendhülsen auf elektrischen Leitern gebräuchlich.In practice, the use such tools mainly for the pressing of so-called ferrules on electrical conductors common.
Übliche Anwendungsbereiche sind 0,5–6 mm2.Usual areas of application are 0.5–6 mm 2 .
Ein Crimpwerkzeug mit starrer Ober- und Unterbacke würde, wenn es mit 0,5 mm2 Hülsen und Leitern funktioniert, sich bei Verwendung von z.B. 6 mm2 nicht mehr schließen lassen und, da die Ratschensperre den Auslösepunkt nicht erreicht, auch nicht mehr öffnen lassen.A crimping tool with a rigid upper and lower jaw, if it works with 0.5 mm 2 sleeves and conductors, would no longer be able to be closed when using, for example, 6 mm 2 and would also not be able to be opened because the ratchet lock did not reach the trigger point ,
Um das dennoch zu ermöglichen, ist ein Backenteil, bei dem an sich bekannten Werkzeug der obere Backenteil, beweglich gelagert. Er gibt also bei Verarbeitung größerer Querschnitte nach, d. h. die Backen öffnen weiter. Die Handhebel schließen wie gewohnt und der Auslösepunkt der Ratschensperre wird erreicht. Damit auf das Werkstück dennoch die zum Verpressen nötige Kraft ausgeübt wird, ist der bewegliche Backenteil gegen ein elastisches Element gelagert, das, je weiter der obere Backenteil ausweicht, eine desto größere Gegenkraft ausübt, wodurch dann auch die für größere Werkstücke nötige Presskraft erzeugt wird, zwar nicht durch die Mechanik der Zange selbst, aber durch eben dieses elastische Element.To make it possible anyway is a jaw part, in the known tool the upper Cheek piece, movably supported. So it gives when processing larger cross sections after, d. H. open your cheeks further. Close the hand levers as usual and the trigger point the ratchet lock is reached. So on the workpiece anyway the necessary for pressing Exercised strength the movable jaw part is against an elastic element stored, the more the upper cheek part dodges, the more greater drag exercises what then also for Larger workpieces need pressing force is generated, not by the mechanics of the pliers themselves, but through this very elastic element.
Dieses elastische Element ist beim an sich bekannten Werkzeug ein Elastomerkissen, das nicht nur schwierig beherrschbare Toleranzen in Härte und mechanischen Abmessungen aufweist, sondern außerdem temperaturabhängig ist. D. h. bei Benutzung in Sommerhitze ist es wesentlich weicher als bei kalten Temperaturen und übt deshalb je nach Einsatztemperatur unterschiedliche Kräfte auf Werkstücke gleicher Größe aus, was bis zu nicht ausreichenden Kräften gehen kann und in mangelhaften Verpressungen resultiert.This elastic element is in the known tool an elastomer cushion that is not only difficult manageable tolerances in hardness and mechanical dimensions, but is also temperature dependent. I.e. when used in summer heat it is much softer than at cold temperatures and exercises therefore different forces depending on the operating temperature Workpieces of the same Size off, what can go to insufficient strength and inadequate Pressing results.
Ein weiterer Nachteil des Elastomerkissens ist die vergleichweise langsame Rückstellung. D. h. bei hoher Kompression dauert es eine gewisse Zeit bis das Kissen die ursprüngliche Form und Position wieder eingenommen hat.Another disadvantage of the elastomer pillow is the comparatively slow reset. I.e. with high compression it takes a certain amount of time to do that Pillow the original Has returned to its shape and position.
In der Praxis bedeutet dies, daß die Verpressung eines kleinen Querschnitts nicht ausreichend ist, wenn kurz zuvor mehrere der größten Querschnitte verpreßt wurden. Ein Effekt, der durch die bei der maximalen Verformung des Elastomerkissens entstehende Wärme noch verstärkt wird.In practice, this means that the compression a small cross section is not sufficient if just before several of the largest cross sections pressed were. An effect that is characterized by the maximum deformation of the Heat generated by the elastomer cushion reinforced becomes.
Eine erfindungsgemäße Abwandlung eines solchen Crimpwerkzeugs mit elastisch gelagertem Backenoberteil besteht darin, daß das elastische Element in engen Toleranzen reproduzierbar, praktisch temperaturunabhängig, gezielt progressiv einstellbar und mit sofortiger Rückstellung versehen ist.A modification according to the invention of such a crimping tool with an elastically mounted upper jaw part is that elastic element reproducible within narrow tolerances, practically independent of temperature, targeted is progressively adjustable and has an immediate reset.
Da in einer Crimpzange der erwähnten Art wenig Einbauplatz zur Verfügung steht, andererseits das elastische Element auf kurzem Weg eine hohe progressive Kraft aufbauen muß, bietet sich ein Paket aus Stahltellerfedern an.Little in a crimping tool of the type mentioned Installation space available stands, on the other hand the elastic element on a short distance a high progressive Must build strength offers a package of steel plate springs.
Einerseits erzeugen solche Tellerfedern selbst in kleiner Bauform hohe Kräfte auf kurzem Weg und lassen sich andererseits durch Vervielfachung und Gegeneinanderlegen zu Paketen mit gezielt progressiver Kennlinie kombinieren.On the one hand, such disc springs produce themselves high forces in a small design on a short way and on the other hand can be multiplied and juxtaposing to packages with a specifically progressive characteristic combine.
