Device for ultrasonic welding

摘要

A device for ultrasonic welding of electrical conductors includes an ultrasonic oscillation-producing sonotrode and two anvils, which as viewed in radial cross section of the article to be welded, form a compression chamber defined by the sonotrade and the anvils for compressing and/or slightly deforming the article to be welded. The two anvils are supported to be moveable relative to one another, such that the two anvils during pivotal movement toward one another, at least partly perform also a displacement movement in the direction of the sonotrode.
