I think this is a cutting/shaping tool that stamps out metal sheets that are then stacked to form laminated components. However, I am not sure if there is an exact term for this. A google search did not yield anything. Hope this at least gives you a start!

Quoted from website below:
"Für Elektromotoren und Spezialtransformatoren von mittleren bis großen Stückzahlen oder mit unterschiedlichen Blech-Geometrien in einem Paket ist Stanzpaketieren die Lösung. Hochkomplexe Stanzpaketierwerkzeuge ermöglichen die Herstellung fertig fallender Pakete"
"Electrical motors and special transformers for medium sized and large series with different shapes of the laminations within one stack are today produced with the interlocking technology. High sophisticated dies allow the production of stacks"
