Faccin 4 Rolls Plate Roll 4HEL

4 Rolls Double Pinch Linear Guides

4HEL is the most precise and easiest to use series of 4-roll bending rolls with total pre-bending. Highly technological and innovative, 4HEL bending rolls assure high-productivity with a speed 3-4 times higher than a traditional pyramid bending roll. Moreover, thanks to their production methods, the 4HEL bending rolls can be effectively controlled through numerical control systems.

All models of Faccin’s 4HEL 4-roll bending rolls are equipped with a rear side roll opposite the feeding side. Used as backing, this roll allows the plate to be aligned in an immediate and accurate manner. The plate, moreover, always remains pinched between the two central rolls, thus avoiding accidental slips. This not only optimises pre-bending and rolling operations, but it also assures safer and more precise machining, with the option of being handled entirely by a single operator and Full CNC.

With the 4 Rolls configuration, the pre-bending operation does not require tilting the plate below the feeding level (as in traditional 3 roll bending rolls) so horizontal feeding tables may be used, for easier feeding of the plate into the machine. With the 4HEL 4 rolls there’s no need to leave free space on both sides of the machines, but only at the selected infeed side.

Faccin 4 Rolls Plate Roll 4HEL Details:

With the 4HEL 4 rolls machine, the plate can be formed in one single pass. In fact after the first pre-bending, the plate is rolled to the desired diameter and then the second end forming is coming automatically.

Cone bending processing made easier by tilting the side rolls and the pinching roll to respectively set the cone angle and drag the sheet at its largest development.

The 4HEL machines are well known for their reliability thanks to their over dimensioned structure and the centralized Lubrication System. The Linear Guide Design (RGS) is increasing their bending precision minimizing the distance between the bending points.

Special design solutions like the Double Bearing System (MCS) are expressly used to have a better absorption of the maximum loads. The combination of top quality components, the Hi-Tech Hydraulic of the FaccinAp and EPS system make the 4HEL one of the most technologically advanced Plate Roll on the market.

4HEL series CNC bending rolls - designed and built by Faccin - are the best solution to bend plates from less than 1m and up to 10m with thickness 5 to 150 mm.
