MAV - VARIABLE GEOMETRY PRESS-ROLL

3-ROLL VARIABLE AXIS PLATE BENDING MACHINE

A 3-roll variable-axis plate rolling machine operating principle is conceptually similar to that of a press-brake, with the top roll pressing the plate between the two side rolls. However, a 3-roll bending machine is much more flexible and accurate, being able to vary the interaxis distance between the bottom rolls. In this regard, DAVI MAV allows for individual, horizontal movement of both side rolls and vertical movement of the top roll. Furthermore, each one of the 3 rolls features rotation drives and can be tilted in every direction for cone bending.

SHORTEST FLAT END AND SAFER OPERATIONS THANKS TO IDEAL TORQUE TRANSMISSION AND ROLLS SYNCHRONIZATION

Particularly on a 3-roll machine, it is of paramount importance to hold as much grip as possible on the plate. Featuring motorized top and side rolls as standard, DAVI all-rolls-drive technology guarantees the optimum torque transmission to the plate and distribution between hydraulic motors. Thanks to this system: no mechanical brakes need to be installed; Rolls speed is automatically and hydraulically synchronized; no risk of plate slippage/falling during pre-bending; plate can always be positioned at the tangent point to achieve the shortest flat end.
