The lefthand scrolling photos: Function elements, assemblies, and units of Wuxi JACK I H Beam Straightening Machine

One set of the machine is mainly composed of:

1. Mechanical Main Frame of I H Beam Straightening Machine:

Include:
1) Straightening Mechanism, this is composed of three pieces of high strength solid straightening rollers, and its driving and guiding units. Of which, the two pieces of smaller straightening rollers are assembled in the upper position in symmetry, and the larger straightening roller is in the bottom position;

2) Two Upper Straightening Rollers Distance Adjusting Mechanism:

a) This is for accommodating on different width of H Beam flange to be straightened;
b) Adjustment on straightening rollers span is in the way of manual turning handwheel;

3) Shaft Box in I H Beam Straightening Machine:

a) This is the mounting base for the 2 pieces of upper straightening rollers, and sliding channel of straightening drive force transmission;
b) There are 2 pieces of shaft boxes in one set of the machine;

4) Mechanical Machine Base Bed of Flange I H Beam Straightening Machine:

a) This consists of slotting table for adjusting on distance between the 2 pieces of upper position straightening rollers at bottom;
b) All the above mentioned working elements of the machine are installed on this mechanical base bed.
 

2. Straightening Force Drive Unit in Flange I H Beam Straightening Machine:

1) In mechanical motor drive structure HYJ series, this unit is 2 sets of 1.5kW A.C. motor;
2) In hydraulic drive structure YTJ and HJ series, this unit is 2 pieces of custom made oil cylinders;
3) Either the A.C. motors or oil cylinders are installed right above the shaft boxes.
 

3. Input and Output Conveyors of I H Beam Straightening Machine:

Both conveyors are idle type: After H Beam is hoisted onto input conveyor of the machine, the sending forward of the H Beam during straightening operation is driven with A.C. cycloidal motor, which is installed on lateral side of the machine mechanical main frame.
 

1) Wide Use: HYJ series takes majority application of the machine: Over 60% in practical use. This benefits from its cost effectiveness (Lower price than other series), and can meet on majority applicating requirement;

2) Straightening Capacity of Motor Drive Flange I H Beam Straightening Machine:

a) Applicable Straightening Material: Chinese Q235 carbon steel, with tensile strength of 370~ 510MPa;
b) Max. Straightening Thickness: 40mm;
3) Standard Models: HYJ-40 and HYJ-800. The difference between the two models is straightening speed: 17m/min. versus 9m/min.
 

Technical Parameters of HYJ Motor Drive Upright Flange I H Beam Straightening Machine:

1) Heavy duty: YTJ series hydraulic drive models has over 2 times straightening capacity in terms of H Beam tensile strength and flange thickness, compared with HYJ motor drive models;

2) Straightening Capacity of Hydraulic Oil Cylinder Drive Flange I H Beam Straightening Machine:

a) Applicable Straightening Material: Chinese Q345 carbon steel, with tensile strength of 510~ 600MPa;
b) Max. Straightening Thickness: From 40mm up to 80mm;
3) 4 Standard Models: YTJ-40/ YTJ-50/ YTJ-60, and YTJ-80, differed based on the largest straightening H Beam flange thickness: 40mm/ 50mm/ 60mm/ 80mm respectively.
 

Technical Parameters of YTJ Series Hydraulic Drive Upright Flange I H Beam Straightening Machine:

1) Workpiece Orientation: H Beam lying flat, instead of standing upright on conveyor of the machine;
2) Double Straightening Efficiency: 2 pieces of H Beam can be straightened at the same time in the machine, instead of 1 piece in HYJ and YTJ series;

3) Analysis on Business Application of WJ Horizontal Flange I H Beam Straightening Machine:

For selling volume, WJ series horizontal models take much less percentage than HYJ and YTJ series upright models. The reasons are:
a) Higher Price: It has double times straightening efficiency compared with HYJ and YTJ series upright model, and hence 40%~ 50% higher quotation;
b) Requirement on Straightening Efficiency: Straightening speed of HYJ and YTJ models is already much quicker than assembly and welding working stations of H Beam Production Line. So, 2 times straightening efficiency is not a plus for selecting proper model of I H Beam Straightening Machine;
4) Straightening Capacity of WJ series horizontal models is lighter than YTJ series hydraulic drive upright models: Up to 40mm H Beam thickness for Q235 material;
5) 2 Standard Models: WJ25 and WJ40
 

Technical Parameters of WJ Horizontal Flange I H Beam Straightening Machine:

1) Suitable for All Steel Structure Parts: Not only H Beam, but also BOX Beam/ Section Steels, and any other long length structure members with square / rectangular/ circular cross section can be straightened in the machine.
2) Workpiece Position: During work, workpiece lay in horizontal position in the machine;
3) Straightening Way: In essence, steel BOX I H Beam Lengthwise Straightening Machine is a hydraulic drive Press. This is the reason that, models of machines is distinguished on the max. straightening force delivered, instead of workpiece specifications;
4) Straightening Capacity: Meanwhile, there is rule of thumb on operating the machine, indicating on the relationship between machine output straightening force and related H Beam flange thickness;
5) 4 Standard Models: HJ20/ HJ100/ HJ200/ HJ300
