Abstract
(DE)
Die Erfindung betrifft eine Ultraschall-Schweißeinrichtung mit einer Ultraschallschwingungen übertragenden Sonotrode (14) und einem auf einem Ambossträger (17) angeordneten Amboss (15), wobei der Amboss (15) auswechselbar auf dem Ambossträger (17) angeordnet ist, derart, dass eine Auflagerfläche (21) des Amboss (15) mit einer durch eine Vorspanneinrichtung erzeugten Normalkraft gegen eine Stützfläche (22) des Ambossträgers (17) anliegt, wobei die Auflagerfläche (21) des Amboss (15) eine Oberflächenhärte aufweist, die größer ist als die Oberflächenhärte der Stützfläche (22) des Ambossträgers (17), wobei die Auflagerfläche (21) zumindest im Bereich einer Teilfläche eine Flächenstruktur aufweist, und wobei die Auflagerfläche (21) zumindest im Bereich der Teilfläche eine Oberflächenrauheit mit Rz/Ra ≥ 2 aufweist.
(EN)
The invention relates to an ultrasonic welding device comprising a horn (14) transmitting ultrasonic vibrations and an anvil (15) arranged on an anvil carrier (17). The anvil (15) is arranged exchangeably on the anvil carrier (17), in such a way that a contact surface (21) of the anvil (15) bears against a support surface (22) of the anvil carrier (17) by means of a normal force generated by a pretensioning device. The contact surface (21) of the anvil (15) has a surface hardness that is greater than the surface hardness of the support surface (22) of the anvil carrier (17). The contact surface (21) has a surface structure at least in the region of a partial area, and the contact surface (21) has a surface roughness where Rz/Ra ≥ 2, at least in the region of the partial area.

L’invention concerne un dispositif de soudage par ultrasons pourvu d’une sonotrode (14) transmettant des vibrations ultrasonores et d’une enclume (15) agencée sur un support (17) d’enclume, l’enclume (15) étant agencée de manière interchangeable sur le support (17) d’enclume, de telle sorte qu’une surface d’appui (21) de l’enclume (15) s’applique au moyen d’une force normale produite par un dispositif de précontrainte contre une surface (22) de support du support d’enclume (17), la surface d’appui (21) de l’enclume (15) présentant une dureté superficielle qui est supérieure à la dureté superficielle de la surface (22) de support du support (17) d’enclume, la surface d’appui (21) présentant une structure plane au moins dans la zone d’une partie de surface, et la surface de support (21) présentant une rugosité de surface avec Rz/Ra ≥ 2 au moins dans la zone de la partie de surface.
