3-roller plate bending machine 3HBR

hydraulicwith mobile control panel

The rolls are made of high quality forged steel, induction tempered and hardened and we polish the rolls after hardening. We also supply special rolls for certain jobs upon request. We use double spherical roller bearings for the rolls in stead of bushings to eliminate bushing tolerances and friction which results in energy loss. The bearings are pre-lubricated and protected by a special washer which doesn't need any lubrication for the entire life of the machine. Very efficient power transmission We connect the hydraulic motors together with planetary gear drives directly on the rolls. This has the advantage of a very efficient power transmission from the motors to the rolls without secondary transmissions and clutches. This system offers the best torque under every work condition. Parallelism The parallelism of the rolls is controlled by massive torsion bars. We eliminate parallelism problems often found on electro hydraulic and electronic systems. This system also gives you the possibility of tilting the rolls for cone work and return to the initial position in a couple of seconds. Standard features: - Two hydraulic readouts for the positioning of the bending (side) rolls - Hardened rolls 50 to 55HRC - Hydraulic conical bending device - Hydraulic drop-end - Centralised ergonomic control panel - Hydraulic overload protection safety system - Operating and instructions manual
