B. Major Steps and Related Equipment in HB Series Welding H Beam Production Line:
Process Technology of Welding H Beam Production Line: (Fig.5)
1. Step One: Plate Cutting with CNC-CG4000 CNC Strip Plate Cutting Machine:
1) Task: This step is for cutting carbon steel plate into strip plates, which will be used as flanges and web, in the subsequent steps of H Beam assembling/ welding and straightening:
2) Wuxi JACK CNC Strip Plate Cutting Machine and cut off strip plates: (Fig.6)
2. Step Two: H Beam Fitting Up and Tack Welding with Welding H Beam Assembly Machine:
1) Task: This step is the first crucial work station at Welding H Beam Production Line:
2) T Beam Assembly: First one piece of flange and one piece of web are assembled into T Beam, and strengthened with CO2 tack welding at the same time;
3) H Beam Assembly: Then, the T Beam is flipped 180°. The 2nd piece of flange is loaded into H Beam Assembly Machine. And the T Beam is assembled and tack welded into H Beam:
4) Wuxi JACK H Beam Assembly Machine works at H Beam Production Line: (Fig.7)
3. Step Three: H Beam SAW (Submerged Arc Welding) with Welding H Beam Welding Machine:
1) Task: This is the central step at Welding H Beam Production Line. The assembled H Beam will be performed with 45° SAW welding;
2) Welding Frequency: There are 4 passes of welding seam in one piece of H Beam. Consequently, there are 2 options of H Beam Welding Machine:
a) Automatic Line: 4 sets of LHC column structure H Beam Welding Machine runs at fully automatic H Beam Production Line: (Fig.8)
b) Semi-automatic Line: 1 set of LHA or LHT gantry frame at manual H Beam Production Line: (Fig.9)
4. Step Four: H Beam Flange Straightening with Welding H Beam Straightening Machine:
1) Why Need: Flange of H Beam has upward bend deformation after SAW welding, because of heat input. H Beam Straightening Machine is for flattening such deformation:
2) Working theory indication on H Beam Straightening Machine: (Fig.10)
3) Major Types of Wuxi JACK H Beam Straightening Machine:
Based on: Tensile strength/ thickness/ deformation position of H Beam flange, there are 3 major types of H Beam Straightening Machine:
(1) Mechanical for light to medium duty H Beam;
(2) Hydraulic for heavy duty H Beam;
(3) Longitudinal deflection H Beam:
(1) Wuxi JACK HYJ800 mechanical H Beam Straightening Machine, for straightening H Beam with material Q235 carbon steel up to 40mm thickness: (Fig.11)
(2) Wuxi JACK YTJ80 hydraulic H Beam Straightening Machine, for straightening H Beam with material Q345 carbon steel up to 80mm thickness: (Fig.12)
(3) Wuxi JACK HJ300 longitudinal H Beam Straightening Machine, for straightening steel structure workpieces along horizontal body: (Fig.13)
5. Step Five: H Beam End Face Milling with H Beam End Face Milling Machine:
1) Task: This step is closing station of Welding H Beam Production Line. It polishes end faces of welding H Beam/ T Beam, removing burr and dirt, making end faces of workpieces gloss and clean:
2) Wuxi JACK DX1520 H Beam End Face Milling Machine works at steel structure facility: (Fig.14)
6. Material Transfer: The WIP (Work in process) working parts transfer among all the above work stations of Welding H Beam Production Line, is implemented with Welding H Beam Turntable Machine.
