Atlantic Plate Rolls
3 & 4 Roll Plate Rolls Including Double Pinch
The 3 roll double pinch plate bending rolls use planetary guides to keep a bigger surface of the plate under pressure during rolling. By doing this, we are able to roll tighter diameters than our competitors.
This technology makes the HACO 3 roll double pinch plate bending roll one of the best rolls on the market today.
|
We use electro-welded frames on and 3 powered rolls with hydraulic motors installed directly on them. The 2 bottom rolls have a planetary movement and the rolls parallelism is controlled by massive torsion bars. We use off the shelf parts, worldwide available. The rolls are made of high quality forged steel, induction tempered and hardened and we polish the rolls after hardening. We also supply special rolls for certain jobs upon request. |
|
|
Bearings |
|
We use double spherical roller bearings for the rolls in stead of bushings to eliminate bushing tolerances and friction which results in energy loss. The bearings are pre-lubricated and protected by a special washer which doesn't need any lubrication for the entire life of the machine |
|
|
|
Hydraulic motors |
|
|
We connect the hydraulic motors together with planetary gear drives directly on the rolls. This has the advantage of a very efficient power transmission from the motors to the rolls without secondary transmissions and clutches. This system offers the best torque under every work condition. |
|
|
Planetary Movement of the Rolls |
|
|
On the left side you can see the planetary movement of the 2 bottom rolls. The parallelism of the rolls is controlled by massive torsion bars. We eliminate parallellism problems often found on electro hydraulic and electronic systems. This system also gives you the possibility of tilting the rolls for cone work and return to the initial position in a couple of seconds. |

Angle Rolls
The HACO HPR series are profile rolls often called angle rolls. We used the same technology as our 3 and 4 roll plate bending rolls which results in a stronger and higher quality machine than most other manufacturers but still at a very competitive price.
The HPR series rolls can bend almost every profile and
section in steel, stainless and aluminum and are virtually
maintenance-free.

Optional CNC control: |
|
|
The very user friendly control uses a simple and intiutive programming process. Our " Auto Teach" system allows for the operator to record all steps of a manually rolled part. All profile ranges can be graphically displayed inside the program for a quick and easy selection. After finishing the programming, the operator can see a bending layout on the display, which will give him or her a precise idea how the part will look like. |
