The proposed machine is suitable to straighten the flanges up to 40 mm.Main features:1. YJZ series straightening machine is used for straightening the deformation
The machine is mainly composed by a base frame where two columns supporting the straightening device are mounted.
One column is fixed, while the other one is adjustable on the base frame according to the web height.
Straightening is carried out by two bending rollers that press the flanges to recover the deformation produced during the previous welding process.
of steel H beam/I beam web and flange.
2. Hydraulic straightening way has large capacity, wide working range, and is highly automatic.
3. The straightening wheel and active roller are made from good quality alloy steel, which
have been heat treated well, thus to ensure a long working life.
4. This series includes YJZ-60B, YJZ-60C, YJZ-80B.
5. Two sides' active rollers are elevated synchronously by hydraulic device and easy to operate.
6. The hydraulic bump station has its own system, which can work for a long life.
