I beam cold bending machine, also called I beam bender, has the advantages of high efficiency, no need for hot processing, high strength of processed arch frame, convenient transportation and so on. It is widely used in the construction of tunnels, subways, hydropower stations, underground caverns and other industries.It is an ideal equipment for steel arch frame manufacturing.

The bending material of this kind of machine is not only for I beam, but also suitable for miner steel, U-shaped steel, C-shaped steel, angle steel, channel steel, track, square steel, steel pipe and other section steel. It allows them to arch, change diameters, and bend at fixed angles.

5 necessary factors and 2 notes for selecting I beam bending machine

(1) The diameter of three top rollers: if it is thin, then it is easy to skid because of small contact surface and easy to deform when bending non-standard steel.

(2) Diameter and stroke of oil cylinder: diameter and stroke determine the size of pressure and the adjustability of bending radius.

(3) The thickness of platform steel plate and the quality of frame: it determines whether the deformation occurs or not when bending large-scale steel.

(4）The power of the motor and the quality of the reducer.

(5) Manufacturer's production scale and service.

Note 1:The type,model and material of the steel.

Note 2:The radius of the bending: It is necessary to find out whether the bending radius conforms to the cold bending coefficient of the steel. Every steel has its own cold bending coefficient. If its cold bending coefficient is exceeded, the steel will deform and the internal structure of steel will be changed,and the quality of steel will be reduced.
