A.     Usage and Application of H Beam Straightening Machine:

1.       Function of HYJ and YTJ Series Mechanical Motorized and Hydraulic H Beam Straightening Machine:

1)       In the process flow of welding H Beam Production Line, H Beam Straightening Machine is used for flattening upward bent flange after submerged arc welding, which is caused from heat input in the SAW process;

2)       For this reason, the equipment is also named as H Beam Flange Straightening Machine;

3)       Working theory indication on Hydraulic and Mechanical Motorized H Beam Flange Straightening Machine: (Fig.1)

4)       A piece of vertical H Beam was being straightened out of Wuxi JACK YTJ50 H Beam Hydraulic Straightening Machine: (Fig.2)

2.       Position of the H Beam Flange Straightening Machine in H Beam Production Line:

It is the fourth set of core equipment in layout of H Beam Production Line, following:

1)       CNC Strip Plate Cutting Machine;

2)       H Beam Assembly and Tack Welding Machine;

3)       H Beam Submerged Arc Welding Machine.

B.     Classification on Wuxi JACK H Beam Flange Straightening Machine:

1.      Vertical and H Beam Horizontal Straightening Machine:

Based on laying orientation of H Beam during straightening, H Beam Straightening Machine has two general types of:

1)       Vertical Orientation H Beam Straightening Machine:

This refers to flange of H Beam is in the position of “Vertical standing”, in H Beam Straightening Machine: (Fig.3)

2)      H Beam Horizontal Straightening Machine:

This refers to flange of H Beam is in the position of “Horizontal lying down”, in H Beam Flange Straightening Machine: (Fig.4)

2.       Using Volume Distribution on 2 Types: In most majority conditions, when mentioning on H Beam Straightening Machine, it refers to vertical standing equipment, which account for over 90% of practical application in H Beam Production Line.

C.     Classification on Vertical Hydraulic and Mechanical Motorized H Beam Straightening Machine in H Beam Production Line:

For Vertical style H Beam Flange Straightening Machine, depending on its driving mode on straightening process, the equipment falls into two sub groups of:

1.       HYJ Series Mechanical Motorized H Beam Straightening Machine: (Fig.5)

1)       Straightening Capacity: This series H Beam Flange Straightening Machine is for straightening H Beam flange with thickness up to 40mm;

2)       The corresponding H Beam raw material grade is: Chinese carbon steel Q235, with its tensile strength in the range of 370~510MPa;

2.       YTJ Series Hydraulic H Beam Flange Straightening Machine: (Fig.6)

1)       Straightening Capacity: This series H Beam Flange Straightening Machine is for straightening H Beam flange with thickness up to 40~ 80mm;

2)      The corresponding H Beam raw material grade is: Chinese carbon steel Q345, tensile strength in the scope of 510~600MPa.

D.    Other Types of Small Volume Application Hydraulic H Beam Horizontal Straightening Machine:

In practical application of H Beam Production Line, there are 2 types of important but not frequently used Hydraulic H Beam Straightening Machine:

1.       WJ Series Hydraulic H Beam Horizontal Straightening Machine: (Fig.7)

1)      Straightening Capacity: The max. H Beam flange thickness that can be straightened in such H Beam Straightening Machine has 2 grades: 25/ 40mm;

2)      The corresponding H Beam raw material is Chinese carbon steel grade of Q235, tensile strength 370~510MPa;

3)      Why Small Volume of This Machine: It has 50% higher quotation than HYJ and YTJ series Vertical orientation H Beam Straightening Machine;

2.      Lengthways Direction Hydraulic H Beam Horizontal Straightening Machine:  

1)       Usage: There is another kind of HJ series Hydraulic H Beam Horizontal Straightening Machine, which is used for straightening the integral piece of H Beam deformation along its lengthwise direction, following H Beam Submerged Arc Welding Machine:

2)       The longitudinal winding welding H Beam to be processed in Wuxi JACK HJ series H Beam Horizontal Straightening Machine: (Fig.8)

3)       Wuxi JACK HJ3000 Horizontal H Beam Hydraulic Straightening Machine in working: (Fig.9)

4)       Wuxi JACK HJ series H Beam Horizontal Straightening Machine Exported to Russia: (Fig.10)

E.     Model List on Various Species of Wuxi JACK H Beam Straightening Machine Applied in H Beam Production Line:

1)      In all, models of high power H Beam Straightening Machine can be listed as below:
