Important Usage and Scope of I H Beam Flange Straightening Machine

A. Why do Steel Structure Customers need I H Beam Flange Straightening Machine:

 

1) Origin: In the process of welding H Beam production, H Beam flanges usually generate deformation after SAW (Submerged arc welding) welding caused from heat input, which should be flattened in special purpose I H Beam Straightening Machine;
2) Working Process: By means of moving through I H Beam Flange Straightening Machine, flanges of the fabricated 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;

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

1. Proper Selection on the Most Fitting Model of I H Beam Flange Straightening Machine:

Should meet below 3 pre-conditions of:

1) Max. straightening capacity of the I H Beam Straightening Machine;
2) Reasonable straightening efficiency that meets customer demand;
3) Suitable purchasing budget on I H Beam Flange Straightening Machine.

 

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

1) Max. Straightening Capacity of the I H Beam Flange Straightening Machine:

This is weighted on the basis of:
a) Max. thickness of H Beam flange --- 40/ 50/ 60/ 80 mm;
b) Carbon steel grade, or tensile strength --- 370/ 510/ 600 MPa;

Max. straightening capacity of each model Wuxi JACK I H Beam Straightening Machine are summarized in below table:

 
 Model Applicable Material Max. Thickness
 HYJ40/ HYJ800 Mechanical drive Vertical Orientation

Straightening Principle of Vertical Orientation I H Beam Flange Straightening Machine

No matter motor drive or hydraulic oil cylinder drive, straightening principle of Vertical orientation H Beam Flange Straightening Machine can be illustrated with below 4 very sketches:

1. The 1st sketch: The General Basic Theory Applied in All Models of Vertical Orientation I H Beam Straightening Machine:

1) Three points being subjected to force, in a confined space, forming squeezing effect for flattening;
2) The bottom solid straightening roller is larger than 2 pieces of up straightening rollers. It revolves without elevation, serving as transmission forward of H Beam through I H Beam Straightening Machine;
3) The downward stroke movement of the 2 pieces of upper rollers generate sufficient squeezing force, straightening flange of H Beam;

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

This gives illustration on where does the straightening power come from: 2 sets of 1.5kW A.C. motor, 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 Machine:

This gives denotation on the straightening power source: 2 pieces of tailor made oil cylinder, also installed in symmetry right above the 2 pieces of upper 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, the role of upper and bottom straightening rollers should be exchanged:
2) The bottom straightening roller will prop up H Beam flange, under the drive of oil cylinder.

Working Manner of Vertical Orientation I H Beam Flange Straightening Machine

Continued from the previous segment, in motor drive and hydraulic cylinder drive Vertical Orientation I H Beam Straightening Machine, the straightening principle is came into reality in the way of:

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

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

2. No.2 Photo: Roller Management in HYJ Series Motor Drive Vertical Orientation I H Beam Straightening Machine:

1) Accommodating H Beam Flange Width: In mechanical Vertical I H Beam Flange Straightening Machine, the distance between the left and right two pairs of rollers is adjusted manually by turning handwheel;
2) Guidance: Correspondingly, the 2 pieces of shaft boxes slide along slotting table of the Vertical I H Beam Straightening Machine;
3) Straightening Driving Force: The downward pressing of the 2 pieces of upper straightening rollers, which is the most important process control parameter in I H Beam Flange Straightening Machine, is driven with 1.5kW A.C. motor;
4) Precision Control: 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 Medium Level YTJ40/50 Hydraulic Vertical I H Beam Straightening Machine:

1) Accommodating H Beam Flange Width: The distance between the two pairs of rollers is also adjusted manually by means of 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: Rollers Management in Heavy Level YTJ60/80 Hydraulic Vertical I H Beam Straightening Machine:
1) Reversed Driving Action: The upward pressing movement of the bottom straightening roller is driven with oil cylinder;
2) Reversed Transmission Action: The 2 pieces of upper straightening roller keeps stationary, just in rotation;
3) Accommodating H Beam Flange Width: The distance between left and right rollers is driven with oil cylinders. This is the unique configuration in heavy duty YTJ-60/80 Hydraulic Vertical I H Beam Straightening Machine.
