1. Calculation on pressing tonnage necessary for straightening designated specification of workpiece: The standard Max. output pressing force in standard models of the H Beam Longitudinal Straightening Machine is from 20Ton to 300 Ton;
2. Make general layout of H Beam Length Direction Straightening Machine based on customer facility surroundings;
3. Make process route for producing and validating Beam Longitudinal Straightening Machine;
4. Have machining on core acting elements, including pressing head, oil cylinder and its guiding bush, ejectors, main beds, pressing beam, etc.;
5. Make sub assembly and final assembly on all the above main units of the H Beam Lengthwise Straightening Machine, control it within stipulated tolerance.

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 |
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”.
