What is Flange Rolling Machine

BIT profile bending machine has a strong section bending ability. It can be used as a large Flange Rolling Machine (Flange Bending Machine, Flange Roll Forming Machine).

Companies using angle iron roller cold rolled flanges
BIT section bending machine exported to Germany many years ago is used for flange rolling

In the past 30 years, due to the rapid development of China’s economy, about 20% of the machines we produce are used for flange rolling, especially large flange rolling that is difficult to mass produce.

Video of flange rolling

For example, PBH-550, the factory manager once released a video to promote its large flange, the excitement can be felt across the screen.

The BIT series profile bending machine bends flat bar(xx axis, such as metal washers) in a harder way, and directly cold-forms the flat steel into a ring or arc with the required diameter. The roundness requirements are determined according to the requirements. It can be used directly on the cylinder body, or used as a connecting flange or support ring on the cylinder body. It is convenient to use and cheap.

Of course, rolled flanges cannot be compared with forged flanges, but they can be used on equipment that does not require pressure, and can also be used as connectors, supports, etc., with a wide range of uses. It is a simplification of the original process (customer steel plate arcing, splicing, correction, cutting inner circle, leveling).

Rolls are hardened & made from high quality steel, three rolls are uniformly driven to ensure the maximum bending torque and automatic compensation of the circumferential speed. The bending force is transmitted to the shaft roller through the movement of the hydraulic cylinder. All three rollers are driven to transmit the maximum torque to the profile, and the end of the profile can be pre-bent when bending the profile.

Hydraulic auxiliary roller for profile bending machine
Up to 6 sets of hydraulic components accurately drive the side rollers of the profile bending machine

By adjusting the two 3D transverse guide rollers, they can be adjusted independently in six directions to ensure the best control of the flatness of the rolling, and to correct the distortion generated during the profile rolling process.


This is a photo sent to me by a customer in Malaysia. He consulted that the BIT type section bending machine can process these parts:

According to the provided parameters, we recommend the PBH-120 profile bending machine and provide relevant parameters. The following are the bending parameters:

“How is big? Could you send me photos please. Btw what type of profile bending machine can make, roll this workpiece? Outer diameter 600mm, inner dia 400mm. Thickness 16mm.”

Based on this situation, we once again recommend another model PBH-200 profile bending machine.

So why would we recommend another machine with a higher section modulus after his doubts?

There are two reasons:

  1. Although BIT’s PBH-120 has been able to fully meet the production requirements of the factory, it may require two roll bendings during the processing process to meet the requirements of cold rolling; PBH-200 has a longer section Modulus bending ability can be rolled at one time, which improves flange production efficiency. And the price of the two machines is not much different, which is a small investment.
  2. The processing capacity of PBH-200 is much stronger than that of PBH-120. The customized PBH-200 can even bend H&I beams. The factory just needs to bend H&I beams, so we recommend PBH-200.
