The highest level of development - 4HEL

Model 4HEL – Pyramidal 4-roller cylinder

All models of 4 roller cylinders 4HEL Faccin They have a rear lateral roller opposite to the introduction side. Used as a stop, this roller allows the sheet to be worked to be immediately and precisely aligned. The latter always remains clamped between the two central rollers, avoiding accidental slipping. This not only optimizes the pre-bending and bending operation, but also allows safer and more precise work, being able to be completely managed by a single operator.

Thanks to the configuration with linear guides of the bending rolls from the series 4HEL, the pre-bending operation does not require the inclination of the sheet below the feeding level, as happens with traditional ones. 3 roller cylinders. In this way, therefore, horizontal feeding tables can be used that facilitate the introduction of the sheet into the machine. Furthermore, free space must not be left on both sides of the machines, but only on the chosen introduction side.

4HEL 4 roller cylinders They allow the sheet metal to be bent to the desired diameter immediately after the first pre-bending. The shaping of the second end follows, that is, the second pre-curving. The processing mode of the machines 4HEL designed and built by Faccin They allow the creation of the cylindrical ferrule in a single pass.

The pyramidal electronic 4 roller cylinders they speed up cone bending work; The possibility of tilting the side rollers and the central roller respectively makes it possible to determine the conical angle and drag the sheet at the height of its greatest development. The cilindros CNC from the series 4HEL designed and manufactured by Faccin are the best solution for bend sheets of a length between 1500 mm and 18000 mm with a thickness of 5 mm to 150 mm.
