Thoman RB4 bending machine

RB4 is a section bending machine with a high roller bending capacity of 15 kW, combined with a flexible machine design. It can bend steel sections with a section modulus of up to Wx = 100 cm3. The front rollers have variable spacing, making it suitable for bending medium to large aluminum and steel sections without damaging them. The machine and control terminal are mobile and movable, and operation can be done using a manual control unit with a magnetic holding unit from a distance of 6 m. It has an advanced and powerful control and drive concept, and a fourth roller or guiding block can be used with its modular tool system. The machine has a very high roller bending performance and options such as a third CNC controlled axis, automatic radius measuring system, hydraulic support and guide rollers with the digital display of the actual position, adjustable calibrating roller for bending L-sections, fourth roller manually or hydraulically adjustable, and supports for the shafts. The technical parameters include a pressure force on the central roller of 35-40 tonnes, speed stepless 0-16 rev/min, torque rated torque max. torque continuous operation of 3 x 2250 Nm and 3 x 3000 Nm, driving power of 15 kW, shaft diameter of 85mm, shaft length of 300mm, stroke X-axis of 400mm, front rollers adjustable of 436-1320mm, length/width/height of 2000/1640/1400mm RB4 with steel section, and weight of 2600 kg. All values refer to standard sizes, and for special applications, the shaft diameter and shaft length may be increased. In most cases, existing rollers can be retained and used.
