The new and patent pending VSA® – technology
allows the operator to bend either very heavy
wall thicknesses or alternatively very small
diameters. This can be realized by a unique
adjustment of the bending geometry. The EVO is
worldwide the only 4-roll plate bender with this
unique feature.
For our clients it means that they are now in a
position to get a machine with up to 85% more
bending moment compared to conventional
bending machines. Additionally they get the
possibility to use super small interchangeable top
rolls for bending tight diameters.
HAEUSLER VSA – SHIFTING THE LIMITS – UP TO 85% MORE ROUNDING POWER
By using two instead of only one pivot point for
each side roll swing arm fixation, the machine can
individually be adjusted either to create a wide
bending geometry for heavy wall thicknesses or a
tight geometry if small diameters shall be bent.
The above shown graphic displays the increase in
bending moment that can be achieved by this new
technology compared to a conventional 4-Roll
Plate Bending Machine.
The complete machine has been designed in such a way that all possible settings can be made without the use of special tools and in the shortest possible time. Not only changing the pivot points of the machine is simple and fast but also for example the changing of a top roll can be done within less than half an hour, due to a newly developed mechanism.
