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

Design sketch on straightening unit working way of steel Beam BOX H Beam Horizontal Press Straightening Machine: (Fig.1)

Fig1 Steel H Beam Horizontal Press Straightening Machine 103
The below 1st handwriting sketch gives illustration on how does the HJ series steel BOX H Beam Longitudinal Straightening Machine straighten on a piece of H Beam along its lengthways direction. You can check it together with the below 2nd to 4th physical photos of the machine mechanical main frame:
1. Straightening Form: The workpiece is straightened in the steel BOX H Beam Longitudinal Straightening Machine segment by segment. Each segment of the workpiece for straightening has adjustable length of 1500 mm to 2000 mm;
2. 3 Points Acting Straightening Theory: The H Beam is pressed against pressing beam of the Horizontal Press Straightening Machine, under the working way of 3 points acting: Point 1 and Point 2 (Please check the 1st sketch and 2nd photo) as subject force points;
3. Straightening Acting Point: The opposing 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 in turn driven with a piece of oil cylinder guided with gloss bushing;
4. Summary on Longitudinal Straightening: In other words, during operation of the steel BOX H Beam Longitudinal Straightening Machine, point 1 and point 2 are fixed positioning points for firmly holding on 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 steel BOX H Beam Lengthways Straightening Machine works in the principle of "Three Points Subjected to Force";
6. Workpiece Release: The 2 pieces of ejectors with 1335 mm distance apart (Shown in the 2nd photo, point 4 and 5) are for pushing the workpiece away from the pressing beam, every time at the completion of lateral acting straightening. In this way, the workpiece is straightened along its length direction segment by segment, until the entire piece going thru straightening unit of the steel structure BOX H Beam Horizontal Press Straightening Machine, and acquire longitudinal straightened workpiece (H Beam here);
7. Workpiece Sending Way: Upon completion of current segment straightening, the H Beam can be pushed forward by hand, and proceed on the next segment of straightening. This explains the reason that, for HJ series steel BOX H Beam Longitudinal Straightening Machine, both input and output conveyors are manual acting type, without motor drive.

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

Operating on Wuxi JACK steel BOX H Beam Horizontal Press Straightening Machine is relatively plain and convenient:

2) During work, operator takes this operating pendant for managing and monitoring on straightening process. He/ she can go to any proper location within certain area to select proper location, acquiring optimum operating status;
3) Al the related actions, the workpiece (H Beam) clamp/ pressing head forward and retreating can all be managed conveniently with this pendant;

2. The 2nd Photo: Precise Straightening Stroke Management in the Steel 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 operating the steel BOX H Beam Longitudinal Straightening Machine, there is a piece of indicating ruler being installed right above the pressing head and oil cylinder;
2) During straightening operation, the indicating index moves to the related indication on the ruler, corresponding to actual straightening stroke of pressing head at that moment, thus acquiring correct negative feedback on straightening stroke control;

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

1) Depending on specifications of workpiece to be straightened, the distance between the 2 pressure subject points: Point 1 and point 2 can be adjusted within the range of around 1500 mm to 2000 mm;
2) This depends on exact design of the steel BOX H Beam Longitudinal Straightening Machine for every customer. Here it just serves as a rough guide on operating the machine properly. In all, the pressure subject points 1 and 2 can be adjusted along guiding slot of the pressing beam flexibly, and secured firmly when finished position adjustment;

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

1) Integral Design: For compact size HJ20 model, its electric control board and operating panel are integrated onto mechanical main frame of the machine;
2) Split Design: The larger models (HJ100 / HJ200, and HJ300) steel BOX H Beam Longitudinal Straightening Machine usually have split type overall structure: Installation of control board and operating panel are separated from mechanical main frame (Including straightening unit) of the machine.
