RBD-4H
4-Roll Hydraulic Plate-Bending Machine
RBD-4H
The 4-Roll Hydraulic Plate-Bending Machine uses top brand components like Siemens, Rexroth, Bosch, Parker, Atos, Telemechanique, SKF, NSK, and FAG to ensure high-quality lifelong performance. Over 50 years of experience in sheet metal bending and thousands of reference customers will guarantee you first class support in any application or maintenance question. With our optional extras you can upgrade the level of automation, which will raise your production and flexibility. Our machines are widely used in shipbuilding, tank and truck industries. Also in the wind-power sector, food and construction sectors.
For medium and heavy bending tasks, the frame is of solid welded construction. All rollers have high-quality, heavy-duty ball bearings, which ensures minimum friction and even rotation of the bending rollers. Hydraulic roller is driven by independent drive motors and planetary gearboxes. Because the planet gears are mounted directly on the rollers, the transmission of force takes place without loss of force or power. The simultaneous use of torsion bars and hydraulic units ensure maximum machining accuracy and production flexibility. The top roll is powered by electrical motor and planetary gearbox. Bottom roll powered with cardan joint system (two rolls powered)
