Usage of BOX H Beam Longitudinal Straightening Machine

A. What Can BOX H Beam Longitudinal Straightening Machine do for Customers:

1. Problem Solved with BOX I H Beam Straightening Machine:

a) At the completion of welding BOX/ I / H Beam production, there are 2 major types of deformation happened on these workpieces;
b) These deformations are caused from SAW/ GMAW welding heat input, and should be corrected with corresponding structures of I H Beam Straightening Machine, so that workpieces BOX/ I / H Beams can be eligible for next step processing:

1) I H Beam Flange Up Bend: This should be straightened with Flange I H Beam Straightening Machine: (Fig.1)

Fig1 H Beam Straightening Machine 2

2) BOX H Horizontal Direction Deflection: This should be straightened with HJ series BOX H Beam Horizontal Press Straightening Machine: (Fig.2)

Straightening Principle of Steel Structure BOX H Beam Horizontal Press Straightening Machine

The 1st handwriting sketch gives illustration on how does the HJ series BOX H Beam Longitudinal 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. General Steps: The workpiece is straightened in BOX H Beam Longitudinal Straightening Machine segment by segment, each segment has adjustable length of 1500 mm to 2000 mm;
2. For straightening current segment, the H Beam is pressed against pressing beam of the BOX H Beam Horizontal Press Straightening Machine, with Point 1 and Point 2 (Please check the 1st sketch and 2nd photo) as touching points;
3. The other side of the H Beam is pressed on Point 3 (As indicated in 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;
4. In other words, during operation of the BOX H Beam Longitudinal Straightening Machine, point 1 and point 2 are fixed points for holding H Beam, and point 3 is for acting and applying straightening force within the stroke of 700 mm;
5. Straightening Theory: In this respect, we can say that BOX H Beam Longitudinal Straightening Machine works in the theory of "Three Points Subjected to Force";
6. Workpiece Release: The 2 pieces of ejectors with 1335 mm distance apart (The 2nd photo, point 4 and 5) are for pushing the workpiece away every time at the completion of straightening, going thru the BOX H Beam Horizontal Press Straightening Machine;
7. Workpiece Sending Way: Upon completion of current segment straightening, the H Beam can be pushed forward by hand, and begin on next segment of straightening. This is the reason that, in HJ series BOX H Beam Longitudinal Straightening Machine, both input and output conveyors are idle type, without motor drive.

Putting into Use on Wuxi JACK BOX H Beam Longitudinal Straightening Machine

 

Operation on HJ Series H Beam Straightening Machine is relatively plain and convenient:

 

1. The 1st Photo: Operating Pendant of the BOX H Beam Horizontal Press Straightening Machine:

The H Beam clamp/ pressing head forward and retreating can all be managed with this pendant;

2. The 2nd Photo: Straightening Management in the BOX H Beam Horizontal Press Straightening Machine:

1) To precisely control forward stroke of the pressing head, which is the most critical process control parameter of the BOX H Beam Longitudinal Straightening Machine;
2) There is a piece of indicating ruler right above the pressing head and oil cylinder;

3. The 3rd Photo: Catering on Different Specifications of Workpieces in BOX H Beam Horizontal Press Straightening Machine:

1) 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 1500 mm to 2000 mm;
2) This depends on specific design of the BOX H Beam Longitudinal Straightening Machine each time, here just as a rough guide, along guiding slot of the pressing beam, and secured firmly;

4. The 4th Photo: Small Model HJ20 BOX H Beam Horizontal Press Straightening Machine:

1) Its control board and operating panel are integrated onto main frame of the machine;
2) The larger models (HJ100 / HJ200, and HJ300 BOX H Beam Longitudinal Straightening Machine usually have separately installation of control board and operating panel.
