Overview of the structure and performance of the PBH section rolling machine
Overview of the structure
The PBH Section Bending Machine is a double-pinch 3-roll bending machine. In the shape of the machine (see Figure 1), the body is welded with a steel plate.
Important notes: All the PBH section bending machines we produce can be installed both in horizontal and vertical positions.
Rotation Transmission Mechanism of PBH Section Bending Machine
The main roller performs a rotary motion by the power transmitted by the hydraulic motor, the gear, and the sprocket. The two side rollers can move in an arc around the central shaft. The power transmitted by the hydraulic motor and the gears is rotated simultaneously with the main shaft. The support rollers are mounted on both sides of the side rollers so that the support rollers can do arc motion with the side rollers. Lifting movements can be made through the respective lifting cylinders.
Performance of PBH series angle rolls
The three rollers of the section bending machine are all driving rollers. The end of the profile can be pre-bent during angle rolling, and the distortion of the profile during angle rolling can be corrected by adjusting the guide roll. All of the above movements are achieved by button operations on the electrical control cabinet.
Note: During the angle rolling process, the rotary motion of the three rollers and the lifting movement of the side rollers cannot be performed at the same time to avoid malfunction. After the three rollers are installed, the side rollers can be lifted and moved. After the mold of three rollers is installed, the side rollers can be raised and lowered.
Pre-bending and bending of the machine
Operations can be divided into symmetrical bending and asymmetric bending (Figure 2):
ADVANTAGES OF PBH SECTION BENDING MACHINE
- Three Power Rotation Rolls and Double-Pinch: PBH 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: PBH 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: PBH 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 PBH benders work closely with bending rolls, adjustable in 6 directions for optimal control of planarity, diameter calibration, and asymmetrical section twisting prevention. 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.
