Straightening Principle of Vertical Flange H Beam Straightening Machinery

For motor drive and hydraulic drive structures of the machine, its straightening principle can be illustrated in below 4 sketches:

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

1) It is three points being subjected to force, implemented in a confined space straightening cavity, forming squeezing effect on H Beam flange;
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 Flange Straightening Machine;
3) Process Control: The straightening stroke, corresponding to downward stroke movement of the 2 pieces of upper straightening rollers, generate sufficient squeezing 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 straightening process, the role of upper and bottom straightening rollers are 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.

Work Manner of I H Beam Flange Straightening Machine

Continued from the previous segment on straightening principle, in HYJ models and YTJ models, the straightening theory 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) Rollers “4/ 5/ 6/ 7” serve as fixture, for supporting and holding on the upright web of H Beam during straightening procedure;
3) General Structure: Such straightening mechanism is applied in both motor drive and hydraulic drive models machine;

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

1) Accommodating varied H Beam Flange Width: The distance between the left and right two pairs of holding rollers is adjusted manually by turning handwheel;
2) Guidance: During adjustment, the 2 pieces of shaft boxes slide along slotting table of mechanical 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 straightening operation, is driven with 2 sets of 1.5kW A.C. motor;
4) Straightening Stroke Precision Control: There are measurement rollers on front wall of straightening units. The rulers are in left and right symmetry, to demonstrate on: The actual position of holding roller span, and real time downward stroke of up straightening rollers;

3. No.3 Photo: Straightening Rollers 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 holding 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 Control in Heavy duty YTJ60/80 Hydraulic I H Beam Flange Straightening Machine:

1) Reversed Straightening Action: Reversed with YTJ40 and YTJ50 models, straightening is by means of the upward pressing stroke of the bottom straightening roller, which is also driven with oil cylinder;
2) Reversed Transmission Action: Meanwhile, the 2 pieces of up installed straightening roller just in revolve without elevation, transmitting on H Beam sending forward. From this, we can see that structure of YTJ60/80 is different from YTJ40/50;
3) Accommodating on varied H Beam Flange Width: The distance between left and right holding rollers are driven with oil cylinders. This is the unique configuration in heavy duty YTJ-60/80 heavy duty models.

Selecting Proper Models of I H Beam Flange Straightening Machine

This should consider below 3 technical points of:
1) Max. straightening capacity of the machine expected by customer;
2) Reasonable straightening efficiency of the machine that meets customer demand;
3) Suitable purchasing budget on I H Beam Straightening Machinery planned by customer.

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

This is weighted on the basis of:
1) Max. thickness of H Beam flange --- 40/ 50/ 60/ 80 mm;
2) Carbon steel grade, or tensile strength --- 370/ 510/ 600 MPa;
Max. straightening capacity of all models Wuxi JACK delivered China H Beam Straightening Machine:
 

2. Straightening Efficiency of I H Beam Flange Straightening Machine:

1) Working Speed: Normally, all models of I H Beam Straightening Machinery work in constant speed, with several grades of 6300/ 9000/ 17000 mm/min. --- It can be denoted by customers;
2) Comparatively, the other 2 critical H Beam production equipment: H Beam Assembly Machine and H Beam SAW Welding Machine work in the pace of adjustable 240~ 2400 mm/min.;
3) So, straightening station is not bottom neck in the process flow of H Beam Production Line.
 

3. Machine Quotation on I H Beam Flange Straightening Machine:

1) HYJ series (Motor drive , vertical) has the most reasonable quotation. This is the reason why it is widely applied. YTJ series (Hydraulic drive , vertical) has higher quotation, but of course heavier straightening capacity;
2) WJ series (Hydraulic drive, horizontal) has the highest quotation, because of its special structure and higher straightening 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;
3) As conclusion, usually straightening efficiency is not an issue for selecting on models of I H Beam Flange Straightening Machine.

This mainly focus on physical modulation of below two points:
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 and deformation condition of H Beam flange;
3) Straightening Accuracy Management: The above two points can all be checked with measurement rulers being installed at straightening mechanism, as shown in the 3rd photo;
4) Straightening Passes: To straighten on the 2 flanges of H Beam, the H Beam should go through the H Beam Straightening Machinery 2 times: 1 flange 1 time.
