The Usage of H Beam Longitudinal Straightening Machine

 

1. The Function of HJ Series H Beam Lengthwise Straightening Machine:

1) At the completion of welding H Beam production, there are 2 kinds of deformation, which should be corrected with 2 types of H Beam Straightening Machine:
2) Flange Up Bend: This should be processed with H Beam Flange Straightening Machine;
3) Length Direction Winding: This should be straightened with HJ series H Beam Length Direction Straightening Machine;
 

The length direction winding welding H Beam that should be corrected with H Beam Longitudinal Straightening Machine:

   Fig1 H Beam Lengthways Straightening Machine
4) Besides H Beam, the HJ series H Beam Length Direction Straightening Machine can also be used for straightening other kinds of structure members with square or rectangular cross section, such as Section Steel, BOX Beam, Cross Beam, etc.

 

2. The Working Way and Advantage of Wuxi JACK HJ Series H Beam Lengthwise Straightening Machine:

1) During working, workpiece is laid on main body of the machine along longitudinal direction, got straightened segment by segment for its whole length.

Model Selection on HJ Series H Beam Length Direction Straightening Machine

1. Different from H Beam Flange Straightening Machine, which gives direct indication on available material and thickness of H Beam for straightening, in HJ series H Beam Longitudinal Straightening Machine, the specification and model are mainly on the basis of max. delivered straightening tonnage;
 

2. Below is rule of thumb on Applicable specifications of H Beam that corresponds with each of the standard model of the HJ Series H Beam Lengthwise Straightening Machine:

 
Model of H Beam Longitudinal Straightening Machine Max. Output 
Pressing Force
Max. Applicable Welding H Beam Specification
Web Height Web Thickness Flange Width Flange Thickness
HJ20 20 Ton 400 10 200 12
HJ100 100 Ton 500 12 400 20
HJ200 200 Ton 600 30 500 35
HJ300 300 Ton 800 32 600 40

 

Straightening Principle of H Beam Lengthwise Straightening Machine

The 1st handwriting sketch gives illustration on how does the HJ series H Beam Length Direction Straightening Machine straighten a piece of H Beam along its longitudinal way. You can check it together with the 2nd to 4th physical photos of the machine main frame:

 
1. The workpiece is straightened in H Beam Longitudinal Straightening Machine segment by segment, each segment has adjustable length of 1500mm to 2000mm;
2. For straightening current segment, the H Beam is pressed against pressing beam of the machine, with Point 1 and Point 2 (Please check the 1st sketch and 2nd photo) as touch points;
3. The other side of the H Beam is pressed on Point 3 (Please check the 1st sketch and 2nd / 3rd photos) by means of a piece of pressing head, which is driven with a piece of oil cylinder guided with bushing. In other words, during operation of the H Beam Lengthwise Straightening Machine, point 1 and point 2 are fixed points for holding H Beam, and point 3 is for acting and applying straightening force in the stroke of 700mm;
4. In this respect, we can say that H Beam Longitudinal Straightening Machine works in the theory of "Three Points Subjected to Force";
5. The 2 pieces of ejectors with 1335mm distance apart (The 2nd photo, point 4 and 5) are for pushing the workpiece away every time at the completion of straightening;
6. Upon completion of current segment straightening, the H Beam can be pushed forward by hand, for next segment of straightening. This is the reason that, in HJ series H Beam Length Direction Straightening Machine, both input and output conveyors are idle type.

Putting into Use of H Beam Longitudinal Straightening Machine

The Operation of HJ Series H Beam Lengthwise Straightening Machine is relatively plain and convenient:

1. The 1st photo gives operating pendant of the machine. The H Beam clamp, pressing head forward and retreating can all be managed with it;
2. The 2nd Photo: To precisely control forward stroke of the pressing head, which is the most critical process control parameter of the H Beam Longitudinal Straightening Machine, there is a piece of indicating ruler right above the pressing head and oil cylinder;
3. The 3rd photo: Depending on specifications of workpiece to be straightened, the distance between the 2 pressure points: Point 1 and point 2 can be adjusted within the range of around 1500mm to 2000mm (This depends on specific design of the H Beam Lengthwise Straightening Machine each time, here just as a rough guide), along guiding slot of the pressing beam, and secured firmly;
4. The 4th Photo: For small model of the H Beam Lengthwise Straightening Machine such as HJ20, its control board and operating panel are integrated onto main frame of the machine. The larger models (HJ100, and HJ200, and HJ300 H Beam Length Direction Straightening Machine) usually have separately installation of control board and operating panel;
5. For more information on preparation and operation of the machine, please check product “HJ20 H Beam Longitudinal Straightening Machine” and “HJ200 H Beam Length Direction Straightening Machine”.

 

Installation of Wuxi JACK H Beam Length Direction Straightening Machine

1. Layout of HJ Series H Beam Longitudinal Straightening Machine:


Below is on site arrangement of HJ300 H Beam Lengthwise Straightening Machine:
1) We can see that the total length of the machine is slight longer than 22m;
2) The suggested width for machine land occupation is 6m;
3) Height of input and output conveyor top surface is 720mm;
4) Hydraulic station and control board of the HJ300 Beam Length Direction Straightening Machine should be put alongside its main body.

2. Main Units of HJ Series H Beam Lengthwise Straightening Machine:

A set of Wuxi JACK HJ Model H Beam Longitudinal Straightening Machine is main composed of:
 

1) Main Frame: The 1st and 2nd photos. It is also working table of the machine. During work, workpiece is laid along longitudinal direction, go through the main frame; Main frame can be further disassembled into pressing head (The 3rd photo) and pressing beam (The 4th photo);
2) Pressing Head (The 3rd photo): This is the moving element in working unit of the H Beam Length Direction Straightening Machine. It is painted into red and black staggered stripe pattern for eye catching purpose. Driven with oil cylinder, the forward and backward movement of pressing head is guided with precisely machined bushing. The pressing head is made of 35 molybdenum complex, and went thru advanced heat treatment, guaranteeing sufficient strength to withstand repeat straightening job on daily basis. It has the same service life as the H Beam Longitudinal Straightening Machine itself;
3) Pressing Beam (The 4th photo): This is the fixed element in working unit of the H Beam Lengthwise Straightening Machine. The 2 pieces of pressure points (Point 1 and 2), as well as the pieces of workpiece ejectors are installed on its internal surface;
4) Input and Output Conveyor, Hydraulic Pump Station, and Control Board: Please check the 2nd photo, it reflects on site arrangement of the Wuxi JACK HJ300 H Beam Length Direction Straightening Machine.

Application and Related Equipment of H Beam Longitudinal Straightening Machine

1. H Beam Length Direction Straightening Machine does not have as large volume of application as H Beam Flange Straightening Machine, which is a requisite one in equipment of H Beam Production Line;
2. On the other hand, H Beam Longitudinal Straightening Machine is not confined to H Beam Production use. As we introduced at the beginning of this page, the machine can be used for straightening lengthways deformation of all working parts with regular cross section. So, it can be applied in other Steel Structure line, such as BOX Beam Production Line;
3. Another equipment which is often worked together with H Beam Lengthwise Straightening Machine is H Beam Fabrication Machine, which produces light duty to medium duty welding H Beam that sometimes need to be straightened along its length direction.
