Problems solved by technology

A disadvantage in this case is that the power transferred to the components to be connected in the radially inner part of the working face is less than the power transferred to the components to be connected in the radially outer part of the working face
Therefore, the solder connection between the components to be joined is uneven

Embodiment Construction

[0081] Figure 1 to Figure 4 The illustrated first torsion ultrasonic welding electrode has two mutually opposed circular end surfaces S1 and S2, and the first threaded hole G1 and the second threaded hole G2 extend toward the center through the middle point of the circular end surfaces S1 and S2. In this case, the circumferential surface U connecting the end surfaces S1 and S2 is cylindrical. The circumferential surface U is a virtual surface at least in some parts, and its cross-sectional geometry substantially corresponds to the geometry of the end surface. The first torsion ultrasonic welding electrode has two substantially cylindrical end portions E1 and E2. The first end portion E1 is defined by the first end surface S1, and the second end portion E2 is defined by the second end surface S2. A central part M having two anvil-like protrusions V1 and V2 which are opposed to each other and protrude from the circumferential surface U is located between the end portions E1 and...

Abstract

The invention relates to a torsion sonotrode, comprising two mutually opposing end faces (S1, S2) and a circumferential surface (U) which surrounds a torsion axis (T) and on which at least one working surface (A1, A2, A3, A4) is provided at a radial distance from the torsion axis (T).

Description

Technical field [0001] The invention relates to a torsion ultrasonic welding electrode, an ultrasonic welding device and a method for forming a welding connection through ultrasonic waves. Background technique [0002] Generally speaking, the present invention relates to the field of ultrasonic welding, especially the field of ultrasonic welding of metal components. Under the action of ultrasonic vibration, each component moves relative to each other substantially parallel to the welding surface, wherein in the direction perpendicular to the component, pressure or welding force is simultaneously applied to the components to be connected. Ultrasonic vibration makes it possible to tear apart and remove the contaminants and oxide layers that normally appear on the surface of the component. Direct contact with the pure metal surface results in a permanent integral connection between the metal components. [0003] From US Patent 3,039,333, an ultrasonic welding device is known, in whi...
