What are the Advantages of the HRB-3 Cylinder Bending Machine?

All-steel welded constructions can be bent with HRB-3 Cylinder Bending Machine. The machines have enough strength and rigidity. They are useful for all kinds of bending works. Hydraulic transmission is used in the hydraulic bending machine. Both ends of the machine tool cylinders are put on the slider. The hydraulic bender has an excellent synchronized movement. This is achieved by the sliding block and torsion shaft. Therefore, the mechanical structure of the hydraulic bending machine is stable and reliable. Moreover, HRB-3 is produced with very sensitive tolerances. Secondly, tension elimination is realized in the big welded components. All of the tensioning points are designed with wide radiuses. Thus, the probable weld cracks are eliminated. Cutting-edge Durma technology produces durable, efficient machines.

The Technology of the HRB-3 Cylinder Bending Machine

Offering double-sided pre-bending, the HRB-3 Cylinder Bending Machine is ideal for bending, especially for large rolling works. All rollers in HRB-3 Cylinder Bending Machines are driven by high torque gearboxes.

Roller placement can perform the bending process most accurately. It has been obtained as a result of long-term tests and calculations. Side rollers, which are placed on planetary arms, operate on independent arc-shaped orbits. Bends with a diameter of 1.2 times the diameter of the upper roll can be obtained. The side rolls from open to close to the top roll. Therefore, the spring back of the sheet is minimized. Thus, perfect pre-bends are obtained.

It is suitable for bending medium sized materials in versatile jobs.

How does the HRB-3 work? To summarize, the sheet is compressed between the side roll and the top roll. The pre bend is done by raising the other side ball to the lowest position. When the sheet is more angled the sheet, better bending is achieved.
