1) In the process of welding H Beam production, flanges usually generate deformation after welding because of heat input;
2) With traveling through H Beam Flange Straightening Machine, flanges of the welded H Beam got flattened, and the entire piece of H Beam can be off line from H Beam Production Line as finished product for Steel Structure use;
3) Taking over 70%~ 80% applicating cases of H Beam Straightening Machine, the H Beam Flange Straightening Machine is the No.1 product of its equipment category.
1) Based on H Beam position during straightening, the H Beam Flange Straightening Machine can be divided into two general groups of Vertical H Beam Straightening Machine and Horizontal H Beam Straightening Machine;
2) Of which the Vertical H Beam Straightening Machine takes over 90% of total share. The above illustration reflects what does it look like of Vertical H Beam Straightening Machine;
a) The mechanical drive H Beam Flange Straightening Machine is fitting for conventional specification of welding H Beam. It can straighten Q235-A carbon steel (Tensile strength 370~ 510 MPa) in the thickness range of 6~ 40mm;
b) The hydraulic drive is heavy duty H Beam Flange Straightening Machine. Its max. straightening capacity is Q345-A carbon steel (Tensile strength 510~ 600 MPa) in the thickness range of 6~ 80mm.
4) In all, there is always the most fitting structure and model of H Beam Flange Straightening Machine applicable for customer selection;
5) Besides, there is another kind of H Beam Lengthwise Straightening Machine for straightening the whole length of welding H Beam;
6) For quick understanding, please check “Review on Wuxi JACK H Beam Flange Straightening Machine”.
This is solid type, made of high strength alloy steel, precisely machined, and went thru strict control heat treatment.
The 2 pairs of supporting rollers hold H Beam in perfect vertical position in flexible way, guided in bush.
3. Assembly of Straightening Rollers, Supporting Rollers, Shaft Box, Slotting Table are all controlled in precise manner in strict control tolerance.
Model | Applicable Material | Max. Thickness |
HYJ40/ HYJ800 Mechanical Vertical H Beam Straightening Machine | Q235, Tensile Strength 370~510 MPa | 40 mm |
YTJ40/ 50/ 60/ 80 Hydraulic Vertical H Beam Straightening Machine | Q345, Tensile Strength 510~600 MPa | 40/ 50 /60 /80 mm |
WJ25/ 40 Horizontal H Beam Straightening Machine | Q235, Tensile Strength 370~510 MPa | 25/ 40 mm |
Here we take HYJ-800 vertical H Beam Straightening Machine as an example:
As can be seen from the above print and photos, operating height level of the HYJ800 is suitable for adult main operator. This is true with all the types and models of Wuxi JACK Vertical H Beam Straightening Machine.
Flange Thickness (mm) | ~ 20 | 20 ~ 30 | 30 ~ 35 | 35 ~ 40 |
Flange Width (mm) | 200 ~ 800 | 350 ~ 800 | 550 ~ 800 | 650 ~ 800 |
HYJ40 and HYJ800 Mechanical type are the most widely selected models in H Beam Flange Straightening Machine.
