PHJ ZHJ Three in One H Beam Assembly Weld Straighten Integral Machine

Quantity:

As the name of Three in One H Beam Assembly Weld Straighten Integral machine implies, the essence of the machine is its integration of the three critical steps (hence traditionally three individual machines) of welding H Beam production into one equipment: H Beam Assembly, H Beam Welding, and H Beam Straightening. This brings along all the benefits of this Three in One H Beam Fabrication machine, including great margin of less equipment investment, less workshop area occupied, less operator needed, and hence less machine maintenance workload as well as running cost.

 

Structure Characteristics of Three in One H Beam Assembly Welding Straightening Integral machine:

  1. The conventional H Beam Assembly& Tack Welding machine, H Beam SAW machine, and H Beam Straightening machine share the similar structure of machine body with input conveyor at its front side, and output conveyor at its rear side. The machine body incorporates sole function of Assembling, SAW, Straightening respectively;

  2. Comparatively, at first glance, the structure of this Three in One H Beam Assembly Welding Straightening machine resembles that of H Beam Assembly& Tack Welding machine: A fixed gantry style main body equipped with conveyors, with the function units installed at the gantry& base machine body;

  3. Different from H Beam Assembly machine, besides Assembly unit, to attain target of welding H Beam production with one machine, structure of this Three in One H Beam Assembly Weld Straighten Integrated machine integrates the corresponding three function units of assembly, welding and straightening into one gantry& base machine body, making it a compact H Beam Assembly Weld Straighten Integral machine;

  4. The original two steps of welding (First step: CO2 tack welding; Second step: SAW welding) performed at H Beam Assembly machine and H Beam SAW machine respectively are now combined into one step of either SAW (Submerged Arc welding, most majority) or CO2 welding (Minority, for light duty welding H Beam only) for this Three in One H Beam Assembly Weld Straighten machine;

  5. In the direction of workpiece going forward, sequence of function units deployed at main body of this compact H Beam Fabrication machine are Assembly unit, Welding unit and Straightening unit. Below is its brief summary:

      i. Assembly unit of Three in One Automated H Beam Fabrication Machine:

       - Includes 3 sets of manipulators (Pulling rod system, hydraulic driven) among input conveyors of the 

          equipment, for rough aligning and positioning of flange and web;

      -  And 2 sets of accurate positioning units (Alignment rollers, also hydraulic driven) for flange and web each;

     ii.  Welding unit of Three in One Automated H Beam Fabrication Machine:

      - SAW (for Light and medium duty welding H Beam, most majority): Includes 2 sets of either China-brand 

        HUAYUAN/ AOTAI, or U.S. brand Lincoln welding source; And 2 sets of automatic flux recycling system;

      - CO2 Welding (for Light duty welding H Beam only, minority): Includes 2 sets of either China-brand 

         HUAYUAN/ AOTAI, or J.P. brand Panasonic welding source;

      iii. Straightening unit of Three in One Automated H Beam Fabrication Machine:

      - Deformation happens at the flanges post welding. To eliminate it, at exit side of the machine following 

        welding unit is straightening unit. It is a powerful down-stroke straightening roller of hydraulic-drive, with heavy 

        force and convenient control.
