The use of gas springs with a surge tank to generate blank holding forces in drawing tools is increasing. These gas spring systems are characterized by an almost constant behaviour of the spring force over the spring displacement. To prevent an increase of the normal pressure with increasing stroke in a drawing process, it is advantageous to obtain a degressive force-displacement behaviour of the gas springs.For this reason, a gas spring system was developed to realize a decrease of the blank holding forces over the stroke without large additional expenditure. The technical realization takes place in an exact controlling of the upper and lower pressure chamber of the nitrogen cylinder.
