Device for welding rod-shaped conductors

A device for welding rod-shaped conductors, said device comprising:

• a compression chamber for receiving joining sections of conductors to be joined together, the compression chamber being limited in a first axial direction (z-axis) on two opposite sides by an active surface of a sonotrode transmitting ultrasonic vibrations in the direction of the z-axis and by a counter surface of a counter electrode and in a second axial direction on two opposite sides by a limiting surface of a slider element which can be moved in the direction of the y-axis and by a limiting surface of a limiting element;
• a knife device including a knife movable in the direction of the z-axis, said knife having a cutting edge which can he moved past the compression chamber and cooperates with a counter cutting edge which limits the compression chamber or is arranged adjacent to the compression chamber, the cooperation being such that joining sections arranged within the compression chamber are severed from the conductors by the knife cooperating with the counter cutting edge;
• and
• a drive motor arranged in an installation space arranged below the sonotrode, the drive motor being connected to a knife holder via a deflection gear in order for the knife to be able to perform a cutting motion, the knife holder being movable in the direction of the z-axis.
