For over 2 decades, Wuxi JACK keeps on providing excellent quality/ the first class service/ reasonable price of China H Beam Straightening Machine for steel structure clients:
Straightening principle sketch and photos of Wuxi JACK I H Beam Flange Straightening Machine: (Fig.1,2)

Wuxi JACK produces 3 branches of I H Beam Flange Straightening Machine, differed on straightening drive force/ H Beam position/ H Beam carbon steel materials:
1) HYJ models motor drive: For H Beam made of Q235 carbon steel, with 370~ 510MPa tensile strength, flange thickness 6mm ~ 40mm, H Beam in vertical standing position;
2) YTJ models hydraulic drive: For H Beam made of Q345 carbon steel, with 510~ 600MPa tensile strength, flange thickness 6mm ~ 80mm, H Beam in vertical standing position;
3) WJ models hydraulic drive: For H Beam made of Q235 carbon steel, 510~ 600MPa tensile strength, thickness 6mm ~ 40mm, H Beam in vertical standing position;
These various models Wuxi JACK H Beam Straightening Machinery plays consistent high performance at steel structure H Beam Production Line:

1. Solid and Strong Straightening Rollers:

1) This critical working element is solid type rollers;
2) The straightening rollers are made of high strength alloy steel, precisely machined, and went thru strict control heat treatment, to guarantee on its superior mechanical performance;

2. Holding and Transmission Rollers in I H Beam Flange Straightening Machine:

1) There are 2 pairs of supporting rollers in the machine, being used for flexibly holding on H Beam web in upright orientation;
2) These supporting rollers are guided precisely in bushing;

3. Final Assembly on I H Beam Flange Straightening Machine:

1) As a heavy force equipment, high strength mechanical frame is of vital importance to guarantee on consistent high straightening performance;
2) Assembly on all assemblies/ units/ components: Straightening rollers/ supporting rollers/ shaft box/ slotting table/ Straightening unit..., are all controlled precisely with strict control tolerance, controlled with IPV internal process validation;

4. Painting and Final Testing on I H Beam Straightening Machinery:

1) The default color of the machine is JACK blue. Of course, customer can denote preferred color based on your preference and company policy;
2) Testing on straightening performance is by means of workpiece test, with the max. rated specification of workpiece.
 

Here we take the most popular model: HYJ-800 as an example:

Physical photos taken in Wuxi JACK workshop:

1) As can be seen from the above 1^st and 2^nd photos, operation is convenient and user friendly. The left and right 2 pieces of upper installed straightening rollers can be adjusted either together, or one by one;

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

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 3^rd 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.
 

4. Empirical Data for Running Wuxi JACK I H Beam Flange Straightening Machine:

1) Rule of Thumb: For all models of Wuxi JACK H Beam Straightening Machinery, there is relationship between thickness and width of H Beam flange. We give these data in manual book of each model;
2) For example, below is empirical Data on operating the HYJ-800 model:

2. 2 Main Driving Forms in I H Beam Flange Straightening Machine:

3. HJ Series Longitudinal Purpose Horizontal Press Straightening Machine:

1) 2 Models: HYJ40 and HYJ800;
2) The Max. Straightening Capability: 40mm thickness, tensile strength 510MPa (Chinese grade Q235);
3) Difference between HYJ40 and HYJ800: Straightening speed, 9000 mm/min. (HYJ40) compared with 17,000 mm/min. (HYJ800).
 

Technical Parameters of HYJ I H Beam Flange Straightening Machine:

1) When to Use: Straightening on heavy duty H Beam, with high tensile strength and large thickness;
2) 4 Classical Models: YTJ-40/ 50 / 60/ 80;
3) The Max. Straightening Capability: 80mm thickness of H Beam flange, tensile strength 600 MPa (Chinese grade Q345).
 

Technical Parameters of YTJ Heavy duty Hydraulic Vertical I H Beam Flange Straightening Machine:

1) Uniqueness: During straightening, H Beam is laid in horizontal position, instead of in vertical standing;
2) Advantage: 2 times straightening efficiency as that of vertical orientation structure;
3) Disadvantage: 50% higher quotation than vertical orientation HYJ and YTJ series;
4) 2 Typical Models: WJ25 and WJ40.
