There will be inevitable bend deformation of the flange slab of the welding finished H beam caused by thermal expansion and contraction. The hydraulic straightening machine is the specific equipment which can be used for deformation straightening.
|Applicable web height||≥200mm|
|Applicable flange slab thickness|| 8-80 mm (material is Q235) |
8-60 mm (material is Q345)
|Applicable flange slab width||200-800mm|
|Straightening speed||5000 mm/min|
|Hydraulic system pressure||16 MPa|
|Base machine power||15kW|
|Lifting roller conveyor length||12 m+12m|
The hydraulic straightening machine has the following features
1. The lifting of top roller is control by hydraulic cylinder, so that the flange slab is under stress. This straightening method has the following advantages: uniform stress, little resilience, simple structure and convenient operation.
2. The front and back floating roller of the machine is controlled by hydraulic cylinder, so the transportation of H beam is stable.
3. The motor makes the driving roller rotate by the cycloid reducer and universal joint. The driving roller can transport the H beam passing through the hydraulic pinch roller to realize flange slab straightening. The power is stable, continuous and powerful.
4. The web clamping device is the combination of hand wheel and hydraulic cylinder, so that it is simple and convenient.
