PBC 4-Roll Section Bending Machine

Performance
PBC Section Rolling Machine

PBC section bending machine excels with robust frames, large shaft sizes, durable bearings, and high drive torque, ensuring unmatched performance and durability compared to competitors.

BIT’s PBC Section Bending Machine is designed specifically for the high-sectional modulus bending process, features innovative design elements aimed at enhancing performance and precision:

  • Monoblock robust frames reduce twists and deformation, stress relief enhances stability, and 5-axis CNC machining ensures precision and longevity.
  • Chrome-nickel alloy steel shafts reduce deflection, ensuring precision bending, running on self-lubricating spherical roller bearings.
  • The PBC machines feature a high torque driven by 3-roll rotation, enabling efficient bending with fewer steps, and making it possible to make a high-sectional modulus bending process a reality.
  • The bottom two rolls of the PBC section rolling machine can move independently of each other, permitting bending symmetrically and asymmetrically and providing the opportunity to perform the pre-bending process on both edges.

BIT uses world-renowned manufacturing standards and unmatched competence to produce the most powerful PBC machines with the highest section bending power on the market.

Advantages of
PBC Section Bending Machine

PBC Double Pinch Section Bending Machine customizes bent profiles from various metals, to reduce costs and minimize tangent/trim. (Pre-bending function with the PBC minimizes the straight tangent flat often required with other machines, saving time and materials.)

In China, BIT’s Profile Bending Machine in standard configuration is delivered with a package of features that usually are not available in the other machine:

  • Three Power Rotation Rolls and Double-Pinch: PBC section benders come with three power rotation rolls, guaranteeing maximum bending torque and automatic speed compensation. The double-pinch feature on lower rolls allows the pre-bending of both the leading and trailing ends of the profile directly on the machine, reducing scrap at segment beginnings and ends.
  • Boasts the Market’s Strongest Full-Frame Design: PBC section bending machines feature robust, spacious structures made from heavy-gauge steel plates, ensuring reliability. Frames are reinforced to minimize deformation, with stress relief after welding ensuring precision and longevity.
  • Combination Bending Molds for any Profiles: PBC section benders come with versatile bending combination molds, facilitating easy bending of various profiles including flat bars, square bars, tees, channels, round bars, square & rectangular tubes, and angles. These universal molds offer practical solutions for diverse bending needs.
  • Efficient Bending Control Hydraulic 3D Guide Rolls: Hydraulic 3D guide rolls on PBC benders work closely with bending rolls, adjustable in 6 directions for optimal control of planarity, diameter calibration, and asymmetrical section twisting prevention, and force the profile to create a spiral if needed. Equipped with angle leg-in bending tooling/cam rollers, aiding in diameter calibration or recovery. Notes: 3D guide rolls with cam rollers for correcting inherent twists when rolling angle leg-in bending, they aid in diameter calibration or recovery.

The following is an example of the PBC series: Heavy-Duty Double Pinch Section Bending Machine all come standard with 8 sets(up to 9 sets) of oil cylinder drives; Standard equipment combination molds can finish processing many standard metal profiles; Low energy consumption – energy saving, lower power than other machines on the market with the same bending capacity.

How it Works

Regardless of your needs and budget for a section bending machine, choosing BIT ensures you benefit from our commitment to quality and integrity in every detail of PBC section bending machines.

PBC section bending machines with a driven-by 3-roll rotation system, makes bending easier and prevents marks on the material, particularly when bending round or square pipes. This design offers superior flexibility, allowing for optimal performance.

The working phases of a section bending machine include loading, roll movement to achieve pinching, the working phase involving pressure increase and profile deformation, and unloading. The machine’s working principle significantly influences these phases, particularly loading and pinching, where adequate roll movement is crucial. This principle ensures efficient loading, secure pinching, precise deformation, and seamless unloading of the bent profiles.

PBC Section Bending Machine
Structural Feature

At BIT, we prioritize precision, durability, and safety in PBC section rolling machines, ensuring they meet the highest standards in the industry.

PBC Series Section Bending Machines are small in size, compact and reasonable in structure, reliable in performance, and convenient in operation and maintenance.

  • Specifically designed for the mass section bending process, featuring a PLC control system that records the position of the rollers in each bend, allowing for easy repetition of operations.
  • PBC section bending machines offer the flexibility to be positioned both vertically and horizontally, accommodating different bending requirements. Working in a vertical position is recommended for smaller-diameter pieces, while larger diameters are better suited for horizontal positioning to prevent the weight of the piece from affecting the results.
  • Self-aligning roller bearings reduce friction, enhancing efficiency, while trackless movement in the pivoting arm minimizes wear.
  • The mold of PBC section bender, forged from 42CrMo and quenched to HB235~270, offers exceptional mechanical properties, strength, and wear resistance, ideal for heavy-duty applications with a prolonged lifespan.
  • An independent mobile operation table or Bluetooth remote control operation ensures operator safety and ease of use.
  • PBC machines are optional equipped with state-of-the-art 5.5 technology, and with remote connectivity, manufacturers can perform software updates and detect anomalies in the machine without the need for onsite visits.

Minimum Bending Radii
and Tolerances

Common Terminology of Profile Bending

The minimum bending radius for a section depends on its properties and bending methods. Advancements in techniques have reduced these minimum radii over time. Normal tolerances for single radius bends adhere to national specifications, while complexities warrant specialist consultation.
Generally, sections can be bent to single or multi-radius curves, parabolic or elliptical shapes, or even co-ordinates. However, physical constraints limit three-dimensional curvature. Thus, detailed discussion during inquiry stages is crucial for complex bending requirements.

The radius of a bend is the most critical piece of information required to curve a steel structure. The radius requirement dictates the bending process used. See also Bend Radius Calculator

MS Section Bender

MS 50 series Section Benders (profile bending machine, Angle Iron Roller)is a small manual hydraulic section bending machine.
Its volume and weight are very small, and of course, its bending ability is also very small. No ability to bend channel and H&I beam profiles.
