Description
Thanks to the special configuration of HAV electronic plate bending rolls, the machine’s 3 rolls move independently – the top roll moves vertically, the lower rolls horizontally – allowing you to adjust, as required, the centre distance between the lower rolls and the distance between the bending points, as is the case on a press brake with variable opening lower die. By reducing to the minimum the centre distance between the lower rolls, the HAV series bending rolls obtain excellent traction of the sheet. In addition, by minimizing the length of the straight part, they offer better quality pre-bending. The maximum centre distance between the lower rolls instead, makes it possible to produce a huge rolling capacity.
Thanks to the horizontal position of the cylinders for lower roll movement, HAV 3-roll variable axis bending rolls are equipped with a reduced height work top. No foundations are therefore required, even for bending rolls with capacity greater than 40 mm. All the HAV series 3-roll bending rolls are fitted with the EPS system for electronic synchronized control of roll parallelism within tolerances of less than 0.2 mm, guaranteed over time as they are not subject to mechanical wear or delay of hydraulic drives. The HAV series models are the right solution to bend plates up to 300 mm thick.
