Section Bending Machine

The Section Bending Machine is a special equipment specially designed for bending and forming of profiles. It can bend metal profiles such as angle steel, flat steel, channel steel, steel pipe, profiled steel, etc. into a cylindrical shape without changing the cross-section characteristics. Or spiral workpiece.

With the international advanced technology, programmable digital control by PLC, all hydraulic drive. This series section bender dedicated to the small straight adge and high precision bending design, profile bending roll feeding can finish by one time for pre-bending section, roll and inspected. Its structure is advanced, short bending straight edge, high precision bending profiles.


Please find the right model according to the maximum bending sectional modulus of profiles in the following parameter table.

The main parameters on form means the max. bending capacity with best working efficiency. If other steel profile like square, angle, only if the bending sectional modulus less than 75 cm3, then it is available to finish bending on this 75.

5. The foot switch is on and off, easy to operate.

6. Change mold groove type, can process various metal profiles, such as Angle steel, flat steel, round steel and other cross section profiles.

7. The machine adapts to medium, mass production, the speed is fast, the efficiency is high.

8.The machine consist of the working part which is welded in the whole basement and transmission part.

The working part made by a frame,three molds and other accessories.

The transmission part consist of motor,speed reducer and other accessories.

9.The transmission of down mold realized from the motor drive the speed reducer.

The meshing of the gear of the output shaft side of the reducer and the gear of the mold to rotate the down mold.

10.The metal pole in the hydraulic oil piston frame drive the up mold to do the movement of the elevation.

11.After finish the bending,rotate the metal pole to make the up mold lifting then unload the workpiece between the up and down mold.
