3-roll Hydraulic Section Bending Machine


3-roll profile bending machine The most common 3-roll hydraulic section bending machine has three rolling rolls, the rolls are hardened and made of high-quality steel, and the bending force is directly coupled to each rolling roll through an independent hydraulic motor through a planet Gear transmission device to transfer to the rolls (independent roll hydraulic drive can ensure that the torque on each roll is optimally distributed during the work phase to achieve higher torque transmission)

Three rolls are driven uniformly to ensure maximum bending Torque and automatic compensation of peripheral speed.

Drive all three rollers to transfer the maximum torque to the profile. One roller is fixed, and the other two rollers move up and down by planetary motion.

Through these movements, the hydraulic profile bending machine can bend any diameter profile, and when bending the profile The end of the profile can be pre-bent. The side rolls are moved through hydraulic cylinders that are transferring the bending force to the shaft rolls. All the three rolls are driven in order to have the maximum torque transmission to the profile.

BIT Serise 3-roll Section Bending Machine Advantage

BIT series 3-roll profile bending machine supports extremely high profile section bending performance. The BIT section bending machine is a technologically advanced, reliable and accurate machine that can ensure excellent bending quality and the highest long-term growth rate.

Three-roll profile bending machine can provide the best results for the bending of mild steel, stainless steel, aluminum, bronze, copper and other steel alloys.

It is very suitable for bending various profiles from small to large, thereby minimizing parts And scrap: flat bar, square & round bar, Tee steel and angle steel in all bending methods, and through a set of BIT’s unique combined cross-section bending die, it can also bend I & H-beam and U-channels.

The BIT series three-roll profile bending machine has the strongest frame that can be found on the market.

The unique full-frame design can withstand all bending forces and guarantees the rigidity and performance of the machine during decades of use by BIT customers; it adopts an extended design In order to increase rigidity and strength, it is manufactured by welding, and after welding by high-quality heavy steel plate, stress is eliminated.

Frame of section bending machine
Thicker and stronger frame of section bending machine

BIT three-roll profile bending machine has up to 6 sets of hydraulic components, which can accurately drive the 3D guide rollers of the profile bending machine

By adjusting two more powerful horizontal hydraulic 3D guide rollers, they can be adjusted in the six directions of up and down, left and right movement and push/pull, respectively, and can support and accompany curved profiles to ensure optimal control of the rolling level Straightness, and correct the deformation of the profile rolling process.

The BIT three-roll profile bending machine is very suitable for manufacturing flanges, greenhouses, railings, large building structures, and various circular patterns in various sizes of sections and pipes.


It is an ideal choice for manufacturing flanges, greenhouses, railings, large building structures, such as circular beams on the roof, domes, abutments, metal pergola, curved captions, tunnel structures… Urban furniture, such as street lights, Protection devices for roundabouts, bicycle racks, tree protection devices, railings, public transport captions, bollards or movable bollards, children’s amusement parks, and circular figures of various sizes and sizes.
