Wuxi JACK I H Beam Flange Straightening Machine, the Most Powerful Steel Structure Straightening Tool for Customer!

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;

2. Subdivision on 2 Main Driving Forms of Vertical Orientation I H Beam Straightening Machine:

Going further, the Vertical orientation I H Beam Straightening Machine has 2 branches of motor drive and hydraulic drive:
1) Motor drive I H Beam Flange Straightening Machine is fitting for straightening conventional specifications of welding H Beam. It can straighten Q235-A carbon steel (Tensile strength 370~ 510 MPa) in the thickness range of 6~ 40mm;
2) Hydraulic drive belongs to heavy duty I H Beam Flange Straightening Machine. Its max. straightening capacity can be up to Q345-A carbon steel (Tensile strength 510~ 600 MPa) in the thickness range of 6~ 80mm;
3. In all, there is always the most fitting structure and specifications of I H Beam Flange Straightening Machine, which is applicable for every customer selection;

4. Another General Group of I H Beam Straightening Machine:

1) Differently, HJ series Horizontal Press I H Beam Longitudinal Straightening Machine is used for straightening deformation along the entire length of welding H Beam:

2) Indication on types of deformed H Beam being applicable for horizontal press I H Beam Longitudinal Straightening Machine: (Fig.4)

3) Wuxi JACK HJ-300 horizontal press I H Beam Longitudinal Straightening Machine is straightening on a piece of BOX Beam: (Fig.5)

1. Straightening Rollers in I H Beam Flange Straightening Machine:

This is solid type straightening rollers, made of high strength alloy steel, precisely machined, and went thru strict control heat treatment to guarantee its mechanical performance.

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

There are 2 pairs of supporting rollers in the H Beam Straightening Machine, which holds H Beam in perfect vertical position in flexible way, guided precisely in bushing;

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

Assembly of Straightening Rollers, Supporting Rollers, Shaft Box, Slotting Table are all controlled in precise manner, with strict control tolerance.

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:

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

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

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

Here we take the most popular model: HYJ-800 vertical orientation motor drive H Beam Straightening Machine as an example:

Front view on the main frame in design drawing of the I H Beam Flange Straightening Machine:

Physical photos of the HYJ-800 Vertical Orientation I H Beam Straightening Machine mechanical main frame taken in Wuxi JACK workshop:

1) As can be seen from the above 1^st and 2^nd photos, working on I H Beam Flange Straightening Machine is relatively simple;
2) The left and right 2 pieces of upper straightening rollers can be adjusted together, or one by one;

3) Process Control on Straightening Process in Vertical Orientation I H Beam Straightening Machine:

This mainly focus on physical modulation of below two points:
a) Span of the 2 pieces of upper position straightening rollers, to be 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;
4) Straightening Accuracy Management: These two adjustments can all be checked with measurement rulers installed at cavity of the I H Beam Straightening Machine, please check the 3^rd photo;
5) Straightening Times: To straighten flanges deformation of welding H Beam, the workpiece H Beam needs to go through the vertical orientation I H Beam Flange Straightening Machine 2 times, 1 piece of flange to be straightened 1 time.
 

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

1) Rule of Thumb: In all the models of Wuxi JACK Vertical I 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 on HYJ-800 Mechanical motor drive Vertical orientation I H Beam Straightening Machine:

1) Application Volume: HYJ40 and HYJ800 models mechanical type motor drive are the most widely selected models in I H Beam Flange Straightening Machine;
2) The Max. Straightening Capability of this series I H Beam Straightening Machine: 40mm thickness of H Beam flange, 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) I H Beam Straightening Machine.

Technical Parameters of HYJ Series Mechanical Vertical Orientation Motor Drive I H Beam Straightening Machine:

1) When to Use: When mechanical type can not meet customer demand, YTJ series hydraulic Vertical I H Beam Straightening Machine are ascending models in terms of straightening capacity;
2) The 4 Classical Models: YTJ-40, and YTJ-50, and YTJ-60, and YTJ-80;
3) The Max. Straightening Capability of YTJ- series I H Beam Straightening Machine: 80mm thickness of H Beam flange, tensile strength 600 MPa (Chinese grade Q345).

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

1) Uniqueness: WJ series hydraulic drive horizontal orientation I H Beam Straightening Machine are niche product: During straightening, workpiece H Beam is laid in horizontal position, instead of vertical as in HYJ and YTJ series;
2) Its advantage is 2 times straightening efficiency as that of vertical orientation I H Beam Straightening Machine;
3) Disadvantage: Horizontal I H Beam Straightening Machine has 50% higher machine price than vertical orientation HYJ and YTJ series;
