Hydraulic dynamic crowning

With the patented hydraulic dynamic crowning of the bending
beam the effect of "bulging" no longer exists when bending sheets
of different materials and different sheet thicknesses. Traditional
bending machines have only a static crowning of the bending
beam, which is useful for just a specific sheet thickness and a
specific bending angle. Contrary to this, the new hydraulic
dynamic crowning of the bending beam makes it possible to bend
a sheet with an exact arbitrary angle independent of sheet
thickness and material. The controlled operation of the beams with
electronic control takes regard of the sheet thickness and backspring
correlations, this then directs the corresponding coefficients
to crown the bending beam, so that a guaranteed optimal bending
results over the whole material length.
