Bending machines of 3 rolls - HAV

Cylinder face

HAV model – 3-roller cylinder variable geometry

The models of series cylinders HAV They are characterized by a very fast and safe pre-bending phase, because the sheet is never inclined but always parallel to the ground. This allows the use of motorized feeding tables with automatic centering systems.

Thanks to the special configuration of the HAV electronic cylinders, the 3 rollers of the machine translate independently – the upper roller moves vertically, the lower rollers with horizontal movement – ​​which allows to adjust, when necessary, the distance between the lower rollers and the distance between the folding points , as it happens in a press brake with lower die of variable opening. By minimizing the distance between the bottom rollers, the bending rolls from series SEA allow to obtain an optimum traction of the sheet. In addition, by minimizing the length of the straight part, they offer a better quality pre-bending. The maximum distance between the lower rollers, on the other hand, produces an enormous bending capacity.

Thanks to the horizontal position of the cylinders for the movement of the lower rollers, the HAV variable axis 3-roller cylinders They have a work surface with reduced height. Therefore, foundations are not necessary, even for rolling machines with a capacity greater than 40 mm. Each 3 roller cylinder from the series HAV has the the EPS system for the synchronized electronic control of the parallelism of the rollers within tolerances lower than 0.2 mm, guaranteed over time since they are not subject to mechanical wear or delay of hydraulic drives. series models HAV are the right solution for plates 300 mm maximum thickness.
