The lefthand scrolling photos: Working elements and units of Wuxi JACK I H Beam Flange Straightening Machine

One set of I H Beam Flange Straightening Machine is mainly composed of:

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

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

2) Two Upper Straightening Rollers Distance Adjusting Mechanism in I H Beam Flange Straightening Machine:

a) This is for accommodating changing width of H Beam flange;
b) It works in the way of manual handwheel for mechanical motorized I H Beam Straightening Machine,
c) And oil cylinder drive for hydraulic drive I H Beam Straightening Machine;

3) Shaft Box in the I H Beam Straightening Machine:

a) This is the mounting base for the 2 pieces of upper straightening rollers, and sliding channel of straightening driving force transmission;
b) There are 2 pieces of shaft boxes in a set of I H Beam Straightening Machine;

4) Machine Base Bed in I H Beam Flange Straightening Machine:

a) This consists of slotting table for adjusting distance between the 2 pieces of upper straightening rollers at bottom;
b) All the above mentioned working elements of the I H Beam Straightening Machine are installed on it.

 

2. Straightening Force Driving Source in I H Beam Flange Straightening Machine:

1) In mechanical motor drive I H Beam Straightening Machine, this is 2 sets of 1.5kW A.C. motor;
2) In hydraulic drive I H Beam Straightening Machine, this is 2 pieces of custom-made oil cylinder;
3) Either the A.C. motors or oil cylinders are installed right above the shaft boxes.
 

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

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

1. Usage and Technical Features of Mechanical Motor Drive Vertical I H Beam Flange Straightening Machine:

1) Vital Importance: HYJ series takes majority application of I H Beam Flange Straightening Machine, over 60% in practical use;

2) Straightening Capacity of Mechanical Motor Drive I H Beam Flange 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 motor drive I H Beam Flange Straightening Machine. The difference between the two models is straightening speed: 17m/min. versus 9m/min.

2. Technical Parameters of HYJ Series Mechanical Motor Drive Vertical I H Beam Flange Straightening Machine:

1. Capability and Technical Characteristics of Hydraulic Drive Vertical I H Beam Flange Straightening Machine:

1) Heavy duty: YTJ series hydraulic oil cylinder drive I H Beam Flange Straightening Machine has over 2 times straightening capacity compared with HYJ mechanical motor drive type;

2) Straightening Capacity of Hydraulic Oil Cylinder Drive I H Beam Flange 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, which is really heavy duty I H Beam Straightening Machine;
3) 4 Standard Models: YTJ-40/ YTJ-50/ YTJ-60, and YTJ-80 hydraulic drive I H Beam Flange Straightening Machine, differed based on the largest straightening thickness: 40mm/ 50mm/ 60mm/ 80mm respectively.

2. Technical Parameters of YTJ Series Hydraulic Drive Vertical I H Beam Flange Straightening Machine:

1. Specialty and Working Mode of Horizontal I H Beam Flange Straightening Machine:

1) Uniqueness of WJ Series Horizontal I H Beam Straightening Machine:

a) Workpiece Orientation: H Beam laying flat, instead of standing upright;
b) Workpiece Quantity: 2 pieces of H Beam being straightened at the same time, instead of 1 piece at any time;

2) Application Volume of WJ Series Horizontal I H Beam Flange Straightening Machine:

Takes much less share than HYJ and YTJ series vertical type. The reason may lie in:
a) Obviously Higher Price: It has double times straightening efficiency compared with HYJ and YTJ series vertical type, and 40%~ 50% higher quotation than HYJ and YTJ series I H Beam Straightening Machine;
b) No Need Higher Productivity: However, straightening speed is already much quicker than assembly and welding working station in H Beam Production Line. So, this is not a plus for selecting proper model of I H Beam Straightening Machine;
3) Straightening Capacity of Horizontal I H Beam Flange Straightening Machine is lighter than YTJ series hydraulic drive vertical type: Up to 40mm thickness for Q235 material;
4) 2 Standard Models: WJ25 and WJ40 Horizontal I H Beam Flange Straightening Machine.

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

1. Applicable Workpieces and Working Mode of HJ Series I H Beam Horizontal Press Straightening Machine:

1) Suitable for All Steel Structure Members: Not only H Beam, but also BOX Beam/ Section Steels, and any other structure members with square or rectangular cross section can be straightened in I H Beam Horizontal Press Straightening Machine. The lefthand 2^nd photo shows a piece of BOX Beam being straightened;
2) Workpiece Position: During work, workpiece lay in horizontal position in the I H Beam Horizontal Press Straightening Machine, as shown in the 1^st photo;
3) Working Theory: In essence, I H Beam Horizontal Press Straightening Machine is a hydraulic drive Press. This is the reason its model is distinguished on the max. straightening force delivered, instead of workpiece specifications;
4) Straightening Capacity: Meanwhile, there is rule of thumb on operating the I H Beam Horizontal Press Straightening Machine, indicating the relationship between output straightening force and related H Beam specifications;
5) 4 Models: HJ20/ HJ100/ HJ200/ HJ300 I H Beam Horizontal Press Straightening Machine.
