Cold bending machine Description:
The bending machine [Cold Bending Machine] is essential equipment for tunnel construction and is mainly used for cold working of steel arches.
cold bending machine is WGJ type. The machine can cold work on rails, I-beams, and H-steel.
The machine has the advantages of high efficiency, no need for hot processing, high arching strength, and convenient transportation. Widely used in tunnel construction, it is ideal equipment for steel arch manufacturing。
