Wuxi JACK H Beam Straightening Machine, Always One Model Fitting for Customer!

The Position and Function of H Beam Straightening Machine:

1. H Beam Straightening Machine is the 3^rd set of core H Beam Production Machine in all types of H Beam Production Line, following H Beam Assembly Machine and H Beam Welding Machine. It is for straightening H Beam flange deformation or whole length curving after submerged arc welding;

2. The Usage of H Beam Straightening Machine is:

1) After the large current submerged arc welding performed at the previous station, flange of H Beam will have upturned deformation due to the effect of heat input, checking at cross section of the H Beam, which should be corrected for its performance;

3. Straightening Capacity of H Beam Straightening Machine for Flange Deformation:

1) Based on driving mode and models of H Beam Flange Straightening Machine, the maximum flange thickness available for straightening can be up to 40mm, 50mm, 60mm, and 80mm;
2) The corresponding Chinese grade of H Beam carbon steel are Q235 (Tensile strength: 370~ 510 MPa) and Q345 (Tensile strength: 510~ 600 MPa).

One set of H Beam Straightening Machine is mainly composed of:

1. Mechanical Main Frame of H Beam Straightening Machine:

Include:
1) Straightening cell, which has three pieces of high strength solid straightening rollers. The two smaller ones are in the top, and one larger one is in the bottom;
2) Top straightening rollers distance adjusting mechanism: This is for accommodating changing width of H Beam flange. It works in the way of manual handwheel for mechanical H Beam Straightening Machine, and oil cylinder drive for hydraulic H Beam Straightening Machine;
3) Shaft box: This is the mounting base for top straightening rollers, and sliding channel of straightening driving force transmission. There are 2 pieces of shaft boxes in a set of H Beam Straightening Machine;
4) Machine base bed: This consists of slotting table for adjusting distance of top straightening rollers at bottom. All the above mentioned working elements of the H Beam Straightening Machine are installed on it.
 

2. Straightening Force Driving Source in H Beam Straightening Machine:

1) In mechanical H Beam Straightening Machine, this is 2 sets of 1.5kW A.C. motor;
2) In hydraulic H Beam Straightening Machine, this is 2 pieces of custom-made oil cylinder;
3) Either the A.C. motors or oil cylinders are installed right above the shaft boxes.
 

3. Input and Output Conveyor of H Beam Straightening Machine:

Both conveyors are idle type: After H Beam is hoisted onto input conveyor of the H Beam Straightening Machine, the sending forward of the H Beam during straightening operation is driven with A.C. cycloidal motor installed on machine main frame.

1. Outline on Usage and Technical Features of Mechanical Drive Vertical H Beam Flange Straightening Machine:

1) HYJ series mechanical H Beam Flange Straightening Machine takes majority application of H Beam Straightening Machine, over 50% in practical use;

2) Straightening Capacity of Mechanical H Beam Flange Straightening Machine:

a) Material: The grade of carbon steel to be straightened in mechanical H Beam Flange Straightening Machine in China is Q235, which has tensile strength of 370~ 510MPa;
b) Thickness: Correspondingly, the largest flange thickness available for straightening is 40mm, which can meet most majority of conventional welding H Beam Production Machine;
3) Model: There are 2 models of this type: HYJ-40 and HYJ-800 H Beam Flange Straightening Machine. The difference between the two models is straightening speed: 17m/min. versus 9m/min.

2. Technical Parameters of HYJ Series Mechanical Drive Vertical H Beam Flange Straightening Machine:

1. Outline on Capability and Technical Characteristics of Hydraulic Drive Vertical H Beam Flange Straightening Machine:

1) YTJ series hydraulic H Beam Flange Straightening Machine has much stronger straightening force compared with HYJ mechanical type, which is not applied for conventional H Beam Production Machine;

2) Straightening Capacity of Hydraulic H Beam Flange Straightening Machine:

a) Material: The grade of carbon steel to be straightened in hydraulic H Beam Flange Straightening Machine in China is Q345, which has tensile strength of 510~ 600MPa;
b) Thickness: Correspondingly, the largest flange thickness available for straightening is from 40mm up to 80mm, which is really heavy duty H Beam Straightening Machine;
3) Model: There are 4 models of this type: YTJ-40, and YTJ-50, and YTJ-60, and YTJ-80 hydraulic H Beam Flange Straightening Machine. The difference between these models is their largest straightening thickness.

2. Technical Parameters of YTJ Series Hydraulic Drive Vertical H Beam Flange Straightening Machine:

1. Specialty and Working Mode of Horizontal H Beam Flange Straightening Machine:

1) WJ series Horizontal H Beam Flange Straightening Machine takes much less share than HYJ and YTJ series vertical type. The reason may lies in:
 

a) It has double times straightening efficiency compared with HYJ and YTJ series vertical type, and 40%~ 50% higher price quotation of the H Beam Straightening Machine;
b) However, straightening speed is already much quicker than assembly and welding in the three critical H Beam Production Machine. So, this is not a plus for selecting proper model of H Beam Straightening Machine;
2) Straightening capacity of Horizontal H Beam Flange Straightening Machine is lighter than vertical type: Up to 40mm thickness for the material of Q235;
3) There are 2 models of its kind: WJ25 and WJ40 Horizontal H Beam Flange Straightening Machine.

2. Technical Parameters of WJ Series Horizontal H Beam Flange Straightening Machine:

1. Workpiece and Working Mode of HJ Series H Beam Lengthways Straightening Machine:

1) Workpiece Type: As mentioned earlier, the working parts applicable for being straightened in HJ Series H Beam Lengthways Straightening Machine are: H Beam, BOX Beam, Section Steels, and other types of steel structure members with square or rectangular cross section;
2) Workpiece Position: During work, H Beam lay in horizontal position in the HJ series H Beam Lengthways Straightening Machine, as shown in the 1^st photo;
3) Working Theory: In essence, HJ Series H Beam Lengthways Straightening Machine is a kind of hydraulic drive Press. This is the reason its model is distinguished on the basis of the max. straightening force delivered, instead of specification of workpiece itself;
4) Straighten Capacity: Meanwhile, there is rule of thumb for the HJ series H Beam Lengthways Straightening Machine, indicating the relationship between output straightening force and specifications of H Beam;
5) Models: There are 4 models of its type: HJ20, and HJ100, and HJ200, and HJ300 H Beam Lengthways Straightening Machine.
