Elasto-Fluid springs of production series WES-F take advantage of the compressibility
of the pre-stressed Elasto-Fluid.
If an Elasto-Fluid spring is loaded with an axial force F, the piston rod and/or the piston
penetrates into the pre-stressed Elasto-Fluid. This further increases the pressure. If
force F is reduced, the Elasto-Fluid relaxes and returns the piston / piston rod to the
starting position.
This technique is used among other things in the rolling mills of cold and hot steel
mills. The upper roller inc. attachments is borne by 2 and/or 4 Elasto-Fluid springs of
production series WES-F. With the help of hydraulics, the upper roller can be lowered
to the desired roll gap. The Elasto-Fluid springs retract accordingly and hold the upper
roller in position. If the upper roller is unburdened, the Elasto-Fluid relaxes and returns
the roller to the starting position.
As an additional function, the Elasto-Fluid springs can serve as pistons and be used
for roller bending. Elasto-Fluid springs of production series WES-F are based on standard
designs, modified and adapted to meet customer requirements.
