Description

Vorrichtung zum Ultraschallschweißen Die Erfindung geht von der überlegung aus, daß es beim Ultraschallschweißen auf eine feste Koppelung zwischen Sonotrodenspitze und Schweißgut ankommt, .da .eine solche nicht nur eine möglichst vollkommene Energieübertragung zur Schweißstelle in Aussicht stellt und damit eine wesentliche Verbesserung .des Wirkungsgrades der Ultraschallschweißung ergibt, sondern auch das unerwünschte Anschweißen der Sonotrodenspitze an das Schweißgut verhindert, weil durch .die feste Koppelung zwischen beiden der zum Verschweißen erforderliche Schlupf fehlt. In geringerem Maße gilt das gleiche auch für den Amboß.Apparatus for ultrasonic welding The invention is based on the consideration from the fact that during ultrasonic welding there is a fixed coupling between the sonotrode tip and weld metal arrives, because .that. such a not only a perfect energy transfer as possible to the welding point and thus a significant improvement .des The efficiency of the ultrasonic welding results, but also the undesired welding prevents the sonotrode tip from reaching the weld metal because of the fixed coupling the slip required for welding is missing between the two. In less The same applies to the dimensions of the anvil.

Es ist bereits bekannt, eine feste Koppelung zwischen Sonotrode und Schweißgut und auch zwischen Schweißgut und Amboß :dadurch herzustellen, daß das profilierte Schweißgut passend in die Sonotrode und/oder .den Amboß greift. Ein Draht wird beispielsweise durch eine im Paßsitz gefertigte, in .die Sonotrode eingesenkte, halbkreisförmige Nut oder ein aufzuschweißendes Prismenstück beispielsweise durch eine eingesenkte dachförmige Nut, .deren Flanken kraftschlüssig das Prismenstück berühren, gehalten.It is already known that there is a fixed coupling between the sonotrode and Weld metal and also between weld metal and anvil: to be produced by the The profiled weld metal fits into the sonotrode and / or the anvil. A Wire is, for example, made with a snug fit, sunk into the sonotrode, semicircular groove or a prism piece to be welded on, for example a sunken roof-shaped groove, whose flanks force-fit the prism piece touch, held.

Bei,der Vorrichtung zum Ultraschallschweißen mit einer Sonotrode als Ultraschallübertrager und einem Amboß nach der Erfindung sind die das Schweißgut berührenden Flächen von Sonotrode und Amboß aufgerauht. Hierzu können die das Schweißgut berührenden Flächen mit Riefen versehen sein, die entweder quer zur Schwingungsrichtung der Sonotrode verlaufen oder kreisförmig eingebracht sind. Ferner können die das Schweißgut berührenden Flächen aus einem Material groben Gefüges, insbesondere Gußeisen, bestehen. Die Oberfläche des Gußeisens kann noch .dadurch besonders rauh gehalten werden, daß beispielsweise die Gußhaut nicht entfernt wird. In den meisten Fällen wird es notwendig sein, die Rauhtiefe .der Oberfläche bzw. ,die eingedrehten Riefen bezüglich Tiefe und Abstand den jeweiligen Umständen anzupassen, wobei eine feinere Aufrauhung zur Übertragung geringerer Schweißleistungen kleiner und dünner Objekte (Folien) genügt und umgekehrt zur Übertragung großer Ultraschalleistungen auf :dickere Bleche und Stücke eine grobere Aufrauhung zweckmäßig ist. Bei .einem derartigen Vorgehen ist nicht nur der Verschleiß der genannten Sonotrodenspitzen gering, sondern es entfällt auch das lästige Anschweißen bzw. Ankleben von Sonotrode und/oder Amboß am Schweißgut, weil durch die kraftschlüssige Energieübertragung zum Schweißgut kein Schlupf zwischen Schweißgut und Sonotrodenspitze einsetzt und somit an dieser Stelle keine Schweißwirkung entsteht.In, the device for ultrasonic welding with a sonotrode as Ultrasonic transmitter and an anvil according to the invention are the weld metal roughened surfaces of the sonotrode and anvil. For this purpose, the weld metal touching surfaces must be provided with grooves, which are either transverse to the direction of vibration the sonotrode or are introduced in a circle. Furthermore, the Surfaces in contact with weld metal made of a material with a coarse structure, in particular cast iron, exist. The surface of the cast iron can still be kept particularly rough as a result be that, for example, the cast skin is not removed. In most cases it will be necessary to measure the roughness of the surface or the grooves that have been screwed in to adapt to the respective circumstances in terms of depth and distance, with a finer one Roughening for the transmission of lower welding performance of small and thin objects (Foils) is sufficient and vice versa for the transmission of high ultrasonic power to: thicker ones Sheets and pieces a coarser roughening is appropriate. With .such a Procedure is not only the wear of the mentioned sonotrode tips low, but the annoying welding or gluing of the sonotrode and / or anvil is also eliminated on the weld metal because of the force-fit energy transfer to the weld metal there is no slippage between the weld metal and the tip of the sonotrode and thus at this No welding effect occurs.
