Work Principle of Wuxi JACK H Beam Flange Straightening Machine

For our motor drive and hydraulic drive types of H Beam Flange Straightening Machine, its principle can be illustrated in below 4 sketches:

1. The 1st sketch: General Principle of I H Beam Flange Straightening Machine:

1) Three points being subjected to force, implemented in a confined space straightening cavity, forming squeezing effect onto both sides top surface and middle bottom surface of H Beam flange, from the 3 pieces of upper (2 pieces) and bottom (1 piece) straightening rollers;
2) Acting Element: The bottom installed solid straightening roller is larger than the 2 pieces of up installed straightening rollers. During straightening, this bottom large roller revolves without elevation, transmitting on sending forward of H Beam, which goes through the entire set of I H Beam Straightening Machinery;
3) Process Control: The straightening stroke, which is downward stroke of the 2 pieces of upper straightening rollers, generate sufficient downward pressing force onto flange of H Beam;

2. The 2nd sketch: Straightening Source in Motor Drive HYJ Series I H Beam Flange Straightening Machine:

This gives illustration on where does the straightening power come from: 2 sets of 1.5kW A.C. motor. The motors are installed in symmetry right above the 2 pieces of upper straightening rollers;

3. The 3rd sketch: Straightening Source in Medium duty Hydraulic Drive YTJ-40/ 50 I H Beam Straightening Machinery:

This gives denotation on the straightening power source in YTJ40 and YTJ50 models: 2 pieces of tailor made oil cylinders. The oil cylinders are installed in symmetry right above the 2 pieces of upper positioned straightening rollers;

4. The 4th sketch: Heavy duty Hydraulic Drive YTJ-60/ 80 I H Beam Flange Straightening Machine:

1) Due to its necessary excessive heavy straightening force involved in the flange straightening process, the role of upper and bottom straightening rollers is exchanged with respect to YTJ40/ 50 models:
2) Under the drive of oil cylinder, the bottom straightening roller props up H Beam flange in heavy force, onto middle of flange bottom surface;
3) In the straightening operation, the 2 pieces of upper straightening rollers only revolve for driving forward H Beam, no elevation.

Work Manner of Wuxi JACK I H Beam Flange Straightening Machine

Continued from the previous segment on straightening principle, in Wuxi JACK motor drive and Hydraulic H Beam Straightening Machine, flange straightening operation is carried out in the way of:

1. No.1 Photo: Straightening Cell in Vertical I H Beam Flange Straightening Machine:

1) Roller “1” corresponds with the bottom position straightening roller, and rollers “2” and “3” correspond with the 2 pieces of upper assembled straightening rollers;
2) Symmetric rollers unit “4/ 5/ 6/ 7” are alignment rollers, for supporting and correct positioning on vertical web of H Beam during straightening operation;
3) Universal Structure: Such straightening mechanism is applied in both motor drive and hydraulic drive models on flange straightening;

2. No.2 Photo: Straightening Rollers Motion Control in HYJ Models Motor Drive I H Beam Flange Straightening Machine:

1) Accommodating varied H Beam Flange Width: The distance between the left and right two pairs of web alignment rollers is adjusted manually by turning handwheel;
2) Guidance: During adjustment on the above mentioned distance, shaft boxes of the 2 pieces of upper straightening rollers slide along T slot, on work table of machine main frame;
3) Straightening Driving Force: The downward pressing of the 2 pieces of upper straightening rollers, which is the most important process control for flange straightening operation, is driven with 2 sets of 1.5kW A.C. motor;
4) Straightening Stroke Precision Control: There are measurement rulers on front wall of straightening units. These 2 rulers are assembled in left and right symmetry, to demonstrate on: The actual position of web alignment rollers span, and real time downward stroke of upper straightening rollers;

3. No.3 Photo: Straightening Rollers Motion Control in Medium duty YTJ40/50 Hydraulic I H Beam Flange Straightening Machine:

1) Accommodating on varied H Beam Flange Width: The distance between the two pairs of web alignment rollers is also adjusted by manually turning handwheel;
2) Straightening Driving Force: The down pressing movement of the 2 pieces of upper straightening roller is driven with vertical mounted oil cylinders;

4. No.4 Photo: Straightening Rollers Motion Control in Heavy duty YTJ60/80 Hydraulic I H Beam Flange Straightening Machine:

1) Swapped Straightening Action between Upper and Bottom Rollers: Different from YTJ40/ YTJ50 models, in YTJ60/80 models, straightening is by means of the upward pressing movement of the bottom straightening roller, onto middle of bottom surface of H Beam flange. This upward pressing movement is also driven with oil cylinder;
2) Swapped Transmission Action on H Beam: Meanwhile, the 2 pieces of upper straightening rollers only revolve, no elevation, forming friction force, and transmitting on H Beam forward. From this, we can see that structure of YTJ60/ YTJ80 main machine is different from YTJ40/ YTJ50;
3) Accommodating on varied H Beam Flange Width: The distance change between left and right web alignment rollers are also driven with oil cylinders. This is the unique design in Wuxi JACK heavy duty YTJ60/ YTJ80 Hydraulic H Beam Straightening Machine.

Selecting Proper Models of Wuxi JACK I H Beam Flange Straightening Machine

This should be considered on below 3 critical technical points of:
1) The max. straightening capacity and special requirement according to customer workpieces: Flange thickness and H Beam yield strength;
2) Straightening efficiency that meets customer demand;
3) Suitable purchasing budget applicable for customer expectation
Hydraulic drive YTJ80
Motor drive HYJ800
Motor drive HYJ40
Hydraulic drive YTJ50

1. The Max. Straightening Capacity and Special Requirement on H Beam Straightening Machinery:

This is weighted on the basis of:
1) The max. thickness of H Beam flange --- 40/ 50/ 60/ 80/ 100mm;
2) Yield strength of H Beam carbon steel --- Medium duty 235MPa; Heavy duty 345MPa, 485MPa;
3) Special size of H Beam --- Technical difficulty of H Beam flange not only lies in the max. yield strength and thickness of flange, but also minimum width of flange. For example, for effective operation of YTJ80, H Beam flange width should be ≧500mm;
 

2. Straightening Efficiency of Motor Drive and Hydraulic H Beam Straightening Machine:

1) Work Speed: Normally, all models of I H Beam Straightening Machinery work in constant speed, with several grades of 6,300/ 9,000/ 17,000 mm/min. --- It can be denoted by customers, which is differed from power of driving motors;
2) Comparatively, the other 2 core machines in H Beam Production Line: H Beam Assembly Machine and H Beam SAW Welding Machine, should all work in the continuously adjustable range of 240- 2400 mm/min.;
3) So, straightening station is not bottom neck in the process flow of welding H Beam Production Line. Usually one set of H Beam Flange Straightening Machine can fully meet on output requirement.
 

3. Investment Budget on I H Beam Flange Straightening Machine:

1) HYJ series (Motor drive, H Beam in vertical) has the least level quotation, and is widely applied in producing small to medium H Beams;
2) YTJ series (Hydraulic drive, H Beam in vertical) has higher quotation, and with heavier straightening capacity. Nowadays, by year 2026, because more and more heavier steel structure construction and bridge building are put into practice, customer selection on YTJ series Hydraulic H Beam Straightening Machine is on the trend of rapid increase;
3) WJ series (Hydraulic drive, H Beam in horizontal) has the highest quotation, because of its special structure and higher straightening efficiency: 2 pieces of H Beam are straightened, doubling on efficiency. However, for most majority customers, higher straightening efficiency is not necessary, because, as discussed previously, straightening station is not bottleneck in H Beam Production Line;
4) As conclusion, usually straightening efficiency is not an issue for selecting on models of H Beam Flange Straightening Machine;
5) An obvious trend over the past several years, to today year 2026 is, more and more Hydraulic H Beam Straightening Machine are selected by customer, taking precedence over motor drive HYJ series. Because more and more heavy duty large H Beam, with yield strength of 345MPa and 485MPa, and larger flange thickness (50mm to 100mm) are applied in steel structure and bridge construction field.

2) Process Control on Straightening Operation in Vertical I H Beam Straightening Machinery:

This mainly focus on correct modulation on below two aspects:
a) Span of the 2 pieces of upper position straightening rollers, fitting for different width of H Beam flange;
b) Downward stroke of the 2 pieces of upper position straightening rollers, based on thickness, deformation and yield strength of H Beam flange;
c) Web is aligned with 2 pairs of symmetrically assembled rollers;
3) Straightening Accuracy Control: The above two points can all be confirmed with measurement rulers being installed at straightening mechanism, as shown in the 3rd photo;
4) Straightening Passes: To straighten on the 2 pieces of flanges in one H Beam, the H Beam should go through the H Beam Straightening Machinery 2 times, with one time H Beam 180° flipping in the process;

FAQ on Wuxi JACK I H Beam Flange Straightening Machine

  • Q Now that there are so many types of H Beam Flange Straightening Machine, how to select the most proper model, so that not only can meet requirement on flange straightening, but also with the least investment budget?

    A Proper selection on H Beam Straightening Machinery depends on below 2 critical factors:
    1. 1) The max. specification of H Beam flange for straightening;
    2. 2) Special specification of H Beam flange;
    This can be explained with 2 business communications between customer and Wuxi JACK in year 2026:
    1. 1) The max. straightening capacity:
    In August 2026, a South American customer asked Wuxi JACK engineer, whether our YTJ80 Hydraulic H Beam Straightening Machine can straighten on H Beam flange with 100mm thickness and 485MPa yield strength (Carbon steel: ASTM A709 WTB 1, Grade 50);
    This is Wuxi JACK engineer response on customer question:
    1. a) For H Beam straightening, because yield strength of customer H Beam is 485MPa, it is hard to straighten on 100mm thickness flange: This will press out obvious dent on surface of H Beam flange. The max. thickness of flange should not exceed 80mm under 485MPa yield strength;
    2. b) For straightening H Beam flange thickness 100mm, the yield strength should not exceed 345MPa;
    1. 2) The min. size of H Beam flange and web for straightening:
    In July 2026, a Bangladesh customer inquired Wuxi JACK on small model HYJ20 motor drive I H Beam Flange Straightening Machine. Size of their H Beam:
    1. a) Flange thickness: 5- 20mm;
    2. b) Flange width: 100- 300mm;
    3. c) Web height: 150- 500mm;
    This should be selected with HYJ20 model motor drive H Beam Straightening Machinery;
    We can also see that, in the field of H Beam Flange Straightening Machine, there is restriction on the minimum width of flange and minimum height of web. For example, for hydraulic drive YTJ80, the minimum width of H Beam flange is 500mm; For YTJ60, it is 350mm.

  • Q How to Manage on Straightening Stroke in Wuxi JACK Motor Drive and Hydraulic H Beam Straightening Machine?

    A
    1. 1) Wuxi JACK adopts on mature and the most cost effective way of downward acting stroke rulers, which are assembled alongside the 2 pieces of upper straightening rollers. This is also conventional design in industry, intuitive, simple and reliable;
    2. 2) Under customer requirement, we also use HMI (Human machine interface) and digital display, with proximity switch to be assembled on straightening rollers, to detect on downward straightening stroke. Of course, this will add on manufacturing cost of H Beam Flange Straightening Machine, and hence its selling price.

  • Q As Professional Supplier on H Beam Straightening Machinery, what is your observance on application trend of this machine in recent five to six years from year 2021 to 2026?

    A
    1. 1) 10 to 20 years ago, the mainstream product in the field of H Beam Flange Straightening Machine was motor drive HYJ800 and HYJ40 models, which have the max. straightening capacity of flange thickness 40mm, with yield strength of 235MPa;
    2. 2) Nowadays, more and more customers select on YTJ series Hydraulic H Beam Straightening Machine, especially those large models: YTJ60 and YTJ80. This is because Steel Structure industry has the trend of more complicated construction using heavier raw materials. And other industries, like Bridge construction industry customers, buy large and heavy H Beam Production Line for their project.

  • Q We know Customer sometimes purchase more than one set of H Beam Welding Machine and CNC Flame Cutting Machine, to meet their target on monthly and annually output on welding H Beam. How about quantity of H Beam Flange Straightening Machine in this regard?

    A
    1. 1) In process technology of welding H Beam production, H Beam flange straightening station is very seldom bottleneck on TAKT time of the entire line. Straightening speed is in the range of 6300mm/min. to 17,000mm/min.. Compared with 300- 2000mm/min. working speed of H Beam assembly and SAW welding, straightening velocity is rather high;
    2. 2) Therefore, one set of H Beam Straightening Machinery can meet customer demand on productivity, no matter it is a HYJ series motor drive type, or YTJ series hydraulic drive machine.

  • Q How to carry out trial run on Motor drive and Hydraulic H Beam Straightening Machine at Wuxi JACK workshop?

    A
    1. 1) What’s special with H Beam Flange Straightening Machine, compared with H Beam Assembly Machine and H Beam Welding Machine is, it can not be commissioned with workpiece loaded before delivery. Which means, it can only be tested in idle running: Try on vertical and horizontal movement of straightening rollers, and web alignment rollers;
    2. 2) This is because actual operation on H Beam flange straightening need to have main machine being installed and consolidated into its foundation, which has around 1,000mm depth into workshop floor. This can only be realized at customer facility;
    3. 3) In August 2026, Wuxi JACK had middle east customer engineers going to our company, for FAT (Factory Acceptance Test) on YTJ80, together with Z30 H Beam Assembly Machine and LHA H Beam Welding Machine. We explained this situation to customer engineers, and gained their understanding and agreement on having workpiece test on Z30 and LHA only.
