Incremental Cold Bending Machine
Beam Cambering Machines/Incremental Cold Bending Machines are specially designed to induce permanent camber into the wide flange, channel, and tubular beams. The resulting curves are perfect, with high precision, good stability, and no deformation.
- Ensures the precise outward angle required for the work.
- Easy to operate.
- Compatible with wide flanges, channel steel, and tubular sections.
- Convenient and independent.
- Accurate and time-saving.
The Cambering Machine and Stretch Forming Machine belong to the same type of cold bending processing equipment/profile bending machine, utilizing full hydraulic control for easy operation and high production efficiency. It can cold bend large I-beams, round pipes, square tubing, and other profiles with a section below 1000mm. The resulting curves are perfect, with high precision, good stability, and no deformation.
The Cambering Machine is mainly used in various industries, including architectural curved steel structures, tunnel support, subway engineering, ceilings, production line tracks, etc. The bending angle of the Cambering Machine is generally not greater than 180°, i.e., half a circle. Typically, the bending allowance of the Cambering Machine is the effective arc length of the profile plus 400mm.
The hydraulic system controls the forward and backward movement of the hydraulic cylinder to push and bend the profile or pipe. The curvature of the bent workpiece is controlled by adjusting the template’s curvature, making it especially suitable for bending large radii in various industries, such as architectural curved steel structures, tunnel support, roof bending beams, subway engineering, curtain walls, ceilings, production line tracks, and more.
The main cylinder provides thrust when the workpiece is pushed upward for bending, shaping the workpiece through the pre-adjusted template. The auxiliary cylinder serves as a clamping cylinder, controlling the forward and backward movement of the inclined plate to clamp the workpiece.
- Turn on the power and start the machine. Check if the hydraulic station motor is rotating correctly. If the motor is in reverse, immediately turn off the power, as prolonged reverse operation can damage the oil pump. Also, check if all movements are normal.
- When bending the workpiece, adjust it to the center position of the hydraulic cylinder. If using a spacer block, ensure it is firm to prevent the workpiece from slipping during clamping, causing injury. After adjustment, clamp the workpiece before performing the bending operation.
- During the workpiece bending process, use segmented movements for bending. If necessary, use dedicated auxiliary fixtures to achieve the bending effect. If needed, add filler material to meet the requirements of the workpiece.
Cambering Machine vs Section Bending Machine for I-Beam Bending
- Beam Cambering Machines specialize in inducing smaller-radius permanent cambers in beams for architectural projects. Typically limited to angles below 180°, they may have precision challenges for larger bends.
- Section Bending Machines, more versatile, handle various metal sections, including I-beams, with greater flexibility and control over larger bending angles. They are capable of achieving exacting tolerances and addressing web buckling concerns, making them suitable for a broader range of applications.
The choice depends on project-specific requirements, with Cambering Machines ideal for focused camber applications, while Section Bending Machines offer versatility and control for diverse bending needs. Read More:
