HRB-4 Series Plate Rolls “Fast, Accurate and Easy to Operate” Four plate rolls are more precise, productive, versatile, faster, safer and easier to operate than three roll machines. They are less dependent on operator competence. Ideal for bending plates up to 200 mm thick. Fast and Reliable Efficient Cycle Times User Friendly, Easy to Operate Increased Productivity Up to 200 mm Bending Thickness

Finest Bending Performance “Durma always strives to be your preferred partner” Robust machine body and construction ensure long machine life and low maintenance. High torque drive system allows HRB to achieve shorter cycle times. User friendly control units makes it possible to be less dependant on operator competence. HRB Series Standard Features Robust Body Structure Machine’s body is strengthened and lowered to minimise the twists and deformation. Machine body, frame and steel bar connections are stress relieved after the welding operation. Planetary Swing Rolls System Electrical System...

HRB Series Standard Features Conical Bending System Strong body and angular bottom and side rolls enables to easily conical bend materials. While machile machines in the market bends conical 3 times of top roll diameter, Durma HRB machines can bend 1.5 times easily. Hydraulic System Rolls are positioned by hydraulic components. The precision of axes are maintained through the use of Bosch Rexroth valves. Pressure safety valves protect against peak pressures and overloads. Synchronized Rolls System Side rolls triggered by 4 different strong hydraulic cylinders. Syncronisation between Thanks...

HRB Series Optional Features Vertical and Side Support System NC Control Unit (HRB-4) In addition to standard user friendly control unit, all bending steps are recorded for operator in teaching mode. All recoreded movements can be repeated using automatic mode. NC control system has capacity to save 70 programs up to 100 steps each. Optional hydraulic side and vertical supports the sheet’s stretch and prevent deterioration of the bending form in big shaped bending. Moveable gauges with hydraulic double cylinders are produced from St52 steel construction. Sheet is easy sliding movement on...

HRB Series Optional Features Both Vertical and Horizontal Working Special solution for corrugated sheet Both Vertical and Horizontal Working This option can be used when the large diameters bendings are not achived with the support systems and the height is limited, its requires a pit and with this pit machine can be more usefull as well as the height advantages. Extended and Profile Bending Rolls Extenden top and side Rolls with the universal bending roll sets bar, profile, angle profile can be easlie produced without needing any additional machinery, if needed special roll set can also be...
