after having been returned I consulted my dictionaries and found:
stauchen = upset, jolt, jump-up, upend,
(stauchformen) form by upsetting
(Niete stauchen) clench/close/upset rivets)
(Stauchschmieden) upset forging
acc. Ernst, Dictionary of Engineering and Technology
in connection with forging I would now prefer swaging.
