The Importance and Scope of H Beam Flange Straightening Machine

1. Why we need H Beam Flange Straightening Machine:

 

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.

 

2. The Scope and Working Capacity of H Beam Flange Straightening Machine:
 

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;

3) Going further, the Vertical H Beam Straightening Machine has 2 branches of mechanical drive and hydraulic drive:

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”.

How to Select a Proper Model of H Beam Flange Straightening Machine

1. With so many choices on hand, the proper selection on H Beam Flange Straightening Machine should meet 3 conditions of:
 

1) Ability on straightening produced H Beam;
2) Reasonable straightening efficiency that meets the demand of expected output;
3) Reasonable purchase budget of H Beam Flange Straightening Machine;

 

 

2. The Sequence to Consider Proper Model of H Beam Flange Straightening Machine:

1) Straightening Capacity of all models of H Beam Flange Straightening Machine can be summarized in below table of: 
 
 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

2) Straightening Productivity: All types of H Beam Flange Straightening Machine work in constant speed, with several specifications of 6300/ 9000/ 17000 mm/min. depending on specific model. Correspondingly, H Beam Assembly Machine and H Beam Welding Machine work in the pace of 240~ 2400 mm/min. So, H Beam Flange Straightening Machine is not bottom neck in the process flow of H Beam Production Line;
3) Machine Price: This is the reason why Horizontal H Beam Straightening Machine is not the preferred choice. Although it has 2 times straightening speed that of Vertical H Beam Straightening Machine.

Straightening Principle of Vertical H Beam Flange Straightening Machine

No matter mechanical drive or hydraulic drive, the straightening principle of Vertical H Beam Flange Straightening Machine can be illustrated with below 4 very similar sketches:
1. The 1st sketch gives the same basic theory applied in all models of Vertical H Beam Straightening Machine: Three Points being subjected to force. The bottom roller is larger than 2 pieces of up rollers. It just revolves, serving as transmission forward of H Beam; The downward stroke of the 2 pieces of upper rollers generate sufficient squeezing force, straightening flange of H Beam;
2. The 2nd sketch gives illustration on where does the straightening power come from in HYJ-series mechanical drive Vertical H Beam Straightening Machine: 2 sets of 1.5kW A.C. motor;
3. The 3rd sketch gives denotation on the straightening power source in medium duty YTJ-40 /50 hydraulic drive Vertical H Beam Straightening Machine: 2 pieces of tailor made oil cylinder;
4. The 4th sketch is on the heavy duty YTJ-60/80 hydraulic H Beam Flange Straightening Machine: Due to its excessive heavy straightening force necessary, the role of upper and bottom rollers should be exchanged. The bottom roller will prop up under the drive of oil cylinder.
 

Working Manner of Vertical H Beam Flange Straightening Machine

Continued from the previous segment, in mechanical and hydraulic Vertical H Beam Straightening Machine, the straightening principle is realized in the way of:
 

1. No.1 Photo: Straightening Cell in All Kinds of Vertical H Beam Straightening Machine:

1) Roller “1” corresponds with the bottom roller, and Rollers “2/3” correspond with the 2 pieces of upper rollers discussed before;
2) Rollers “4/5/6/7” are for supporting and holding the vertical web of H Beam during working of the H Beam Flange Straightening Machine;
3) Such kind of arrangement on straightening and supporting rollers is true for both mechanical and hydraulic Vertical H Beam Straightening Machine;
 

2. No.2 Photo: Roller Management in Mechanical Vertical H Beam Straightening Machine:

1) In mechanical Vertical H Beam Flange Straightening Machine, the distance between the left and right two pairs of rollers is adjusted manually by turning handwheel;
2) Correspondingly, the 2 pieces of shaft boxes slide along slotting table of the Vertical H Beam Straightening Machine;
3) The downward pressing of the 2 pieces of upper straightening rollers, which is the most important process control parameter in H Beam Flange Straightening Machine, is driven with 1.5kW A.C. motor;
4) There are measurement rollers to display the actual position of roller span, as well as downward stroke of straightening rollers;
 

3. No.3 Photo: Rollers Management in YTJ40/50 Hydraulic Vertical H Beam Straightening Machine:

1) The distance between the two pairs of rollers is also adjusted manually by means of handwheel;
2) The down pressing movement of the 2 pieces of upper straightening roller is driven with vertical mounted oil cylinders;
 

4. No.4 Photo: Rollers Management in YTJ60/80 Hydraulic Vertical H Beam Straightening Machine:

1) The upward pressing movement of the bottom straightening roller is driven with oil cylinder;
2) The 2 pieces of upper straightening roller keeps stationary, just in rotation;
3) The distance between left and right rollers is driven with oil cylinders. This is the unique configuration in YTJ-60/80 Hydraulic Vertical H Beam Straightening Machine.

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.

3. Operation of H Beam Flange Straightening Machine:

1) As can be seen from the 1st and 2nd photos, operation of the H Beam Flange Straightening Machine is relatively simple;

2) The left and right top straightening roller can be adjusted together, or one by one;

3) Process control on straightening process in Vertical H Beam Straightening Machine mainly focus on physical modulation of two points:

a) Span of the 2 pieces of upper position rollers, to be fitting for different width of H Beam flange;
b) Downward stroke of the 2 pieces of upper position rollers, based on thickness and deformation condition of the flange;
4) These two adjustments can all be checked with measurement rulers, please check the 3rd photo;
5) To straighten flange deformation of a piece of welding H Beam, the H Beam need to go through the vertical H Beam Flange Straightening Machine 2 times.
 

4. Empirical Data in H Beam Flange Straightening Machine:

1) In all the models of Vertical H Beam Straightening Machine, there is relationship between thickness and width of flange available for straightening, which we give in manual book of each model;
2) For example, below is empirical Data for HYJ-800 Mechanical 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
