1) When Need: In the process technology route of welding H Beam Production Line, H Beam flange tilt up after the 3rd station of submerged arc welding. This flange deformation is caused from heat input in the SAW process, and should be removed with corresponding I H Beam Straightening Equipment;
2) Straightening Principle: Both sides of the H Beam flange will be downward pressed firmly with 2 pieces of rolling rollers from its top side. Meanwhile, bottom side of the flange is supported/ propped up and transmitted with a larger rolling roller:
“3 points subject to force” principle in I H Beam Straightening Machine: (Fig.1)
The above 3 pieces of straightening rollers form up straightening cavity of the machine;
3) Operating Way: Driven with A.C. motors of the input and output conveyors, H Beam goes through straightening cavity of the machine in constant speed, got straightened in the process:
H Beam being straightened out of Wuxi JACK YTJ80 H Beam Hydraulic Straightening Machine: (Fig.2)
Based on orientation and position of H Beam during straightening operation, the machine has two general types of:
In this structure, H Beam “stands” in upright position on conveyors of the machine during straightening: (Fig.3)
In this structure, H Beam “lies” flat on conveyors of the machine during straightening: (Fig.4)
Over 90% of flange purpose I H Beam Straightening Machine in practical use is with H Beam standing up position. It is default structure of the machine.
Drive Form: 2 sets of A.C. motors in straightening cavity of the machine;
Straightening Capacity: This series is standard configured machine in conventional H Beam production line, for straightening on:
a) H Beam flange with thickness up to 40mm;
b) H Beam is fabricated from Chinese grade Q235 carbon steel, tensile strength in the range of 370~510MPa;
Drive Form: 2 pieces of oil cylinders in straightening cavity of the machine;
Straightening Capacity: This series is applied on heavy workpieces, for straightening on:
a) H Beam flange thickness up to 40~ 80mm;
b) H Beam is assembled and welded from Chinese grade Q345 carbon steel, tensile strength in the scope of 510~600MPa;
Structure of YTJ40/50 is different from YTJ60/80, considering straightening effect on H Beam:
a) Wuxi JACK YTJ50 I H Beam Hydraulic Straightening Machine: (Fig.6)
b) Wuxi JACK YTJ80 I H Beam Hydraulic Straightening Machine: (Fig.7)
a) Straightening Capacity: The max. H Beam flange thickness has 2 grades: 25/ 40mm;
b) H Beam is assembled and welded from Chinese grade Q235 carbon steel, tensile strength 370~510MPa.
1) Specialty: This niche group HJ series steel BOX H Beam Horizontal Press Straightening Machine is featured product of Wuxi JACK. Very few Chinese companies have technical strength and experience to design and produce it;
2) Usage: This machine straightens on the integral piece of H Beam (Or long other steel structure workpieces) along its lengthwise direction, similar to ASM series Angle Steel Straightening Machine:
Longitudinal winded H Beam for Horizontal Press Straightening Machine: (Fig.9)
3) Application: Besides H Beam, other long length “slim” steel structure workpieces, like BOX Beam/ Pipe/ Section Steel... can all be processed in high efficiency with this niche group of the straightening equipment:
