When bending I and H beams, bending along the hard axis (x-x axis or strong axis) can lead to unacceptable deformation, especially in the web area. To avoid this issue, companies specializing in steel section bending typically employ advanced technology and equipment. The key challenge is to maintain the integrity of the web during the bending process, which requires precise control.
PBC profile bending machines are specifically designed to address these challenges. Whether bending large cross-sections of H-beams or I-beams, PBC machines ensure that the web remains intact and free from deformation.
PBC Machines Solve the Hard-Axis Bending Problem
Profile bending machines are typically used for bending beams along the hard axis. To prevent web deformation, additional custom hydraulic stretching systems (rollers that extend above the web of I-beams and H-beams) are used to apply tension to the outer flange, keeping the web under tension and preventing distortion. However, pulling on the outer flange may cause it to dip, which may or may not be acceptable. Through PBC’s mature roll bending technology and specialized hydraulic stretching system, tension is applied to the outer flange, preventing web deformation while maintaining the beam’s overall integrity.
During the hard-axis bending process of I-beams and H-beams, PBC machines are equipped with reinforced frames and precision hydraulic stretching systems that balance compressive and tensile forces. This ensures the stability of the bending process, even when handling heavy materials and large cross-section profiles, preventing deformation.
Customized Solutions for Heavy-Duty Applications
PBC machines are not only highly adaptable but can also be customized according to the specific requirements of each project. For heavy-duty applications, such as bending large cross-sections of H-beams and I-beams, PBC machines can be configured with specialized rollers and hydraulic systems to handle the additional pressure involved in hard-axis bending. PBC machines can bend multiple radii and off-axis profiles, offering unparalleled flexibility to meet various bending needs.
