Four-roll round bending machine RBA

Max. Sheet thickness 4.5 mm; min. Roll diameter 42 mm; Max. Roller length 1530 mm. The automatic round bending machine (RBA) enables flexible and high-precision pipe production for an industrial standard.

The automatic round bending machine (RBA) is our high-end product in the area of rounding various sheet metal parts and shapes. Accuracy and speed, the RBA combines these features and therefore fits into any modern sheet metal processing. Whether manual loading and unloading or complete integration into a fully automatic pipe production line, both scenarios can be covered by the RBA. Thanks to the modern PLC, not only can programs be saved, but communication with other systems can also be established.

The RBA has a four-roller design. The rollers are positioned with the help of stepless motors. The motors provide feed, bending angle and sheet tension. Control panel with a PLC control and touchscreen for setup and automatic processes.

Standard features:

Four-roller design with high-strength rollers
Motorized roller positioning, infinitely variable
Sheet metal stop and hinged bearing pneumatically operated
PLC control of the machine with operation via touchscreen
Program memory, safe against power failure, with password protection
Individual program setting for different pipe profiles
Compact and maintenance-friendly construction of the machine
