HELLER HYDRAULIC 4 ROLL
|
 Whether you are a
job shop or manufacturer, the Heller 4 Roll is the best solution.
Every machine, size for size, can roll 30% tighter diameters than
any type roll and 30% thinner material than 3 roll double pinch
machines. These features, combined with the advanced technology
incorporated in all aspects of the Heller Roll, make it up to 300%
more efficient than 3 roll machines. The following graphs explain
why.
| |
|
By using exclusive planetary guides: available on
Heller Rolls, we are able to keep approximately 50% more area of the
plate under bend pressure during the
rolling operation, thereby allowing the Heller Rolls to roll down to
1.1 the upper roll diameter. This allows Heller Rolls to have a 30%
advantage on tight diameters.
|
Spherical roller
bearings:
extremely energy efficient. Eliminates bushings and the
necessary running tolerance they  require. A negligible loss of energy due
to friction whereas bronze bushings take 25-30% of available energy to
overcome inherent friction. Lubricated for life.
- Key Benefits
![[Bullet]](images/bullet.gif) Easy
to use
![[Bullet]](bullet.gif) Only
one operator needed
Fast
and accurate |
Planetary drive:
eliminates complicated transmission systems which are not energy
efficient. Delivers in excess of 98 % of all created energy to roll
surface. Also eliminates the need for clutches and complicated
synchronization devices.
|
Torsion bar parallelism: unlike electronic systems or
proportional value systems, which maintain a theoretical balance,
the Heller Roll maintains a
mechanical finite parallelism through our exclusive torsion bar
system which allows the machine to be adjusted to its full conical
tilt and  back to parallel in only 5
seconds for the life of the
machine. | |
|
 Cone rolling: through exclusive technology, Heller
Rolls can develop cones as easily as competitive machines can
develop cylinders. And it eliminates scarring on the surface of
shell or roll and also eliminates, in most cases, the need for
grinding the lamination (bullnosing) on the minor diameter
edge.
