ZHJ8020 H Beam Assembly Weld Straighten Integral Machine for Beam Manufacture

Quantity:

ZHJ-series High Efficiency H Beam Assembly Welding Straighten Integral machine is a kind of advanced and high-efficient H beam manufacture machine, applicable for producing light-duty and medium-duty H beam of single pass fillet welding seam height 12mm and less.

ZHJ8020 is the largest one of standard ZHJ-series High Efficiency H Beam Assembly Weld Straighten Integral machine, for manufacturing welding H Beam of web height 200~ 2000mm (Other parameters are same as that of ZHJ8015 and ZHJ8018).

 

1. Main specification of ZHJ8020 Automatic H Beam Assembly Weld Straighten Integral machine lists below:

1) Welding:                                     SAW (Submerged Arc Welding) and or GMAW CO2

2) Weld-toe size of single pass:       8~12 mm

3) Input conveyor:       Total length 10m, into 3 segments,of which one is motor-driven

4) Output conveyor:                        Total length around 10m, of which two can be elevated

5) Assembly, welding and straightening speed:  Same of 0.2~ 1.2m/min

6) Total power:                                Main machine is 20KW (two welding power is 140KVA)

7) Machine size:                              Length × width × height =32m×4m×4.2m

 

2. Main Units of ZHJ8020 Automatic H Beam Assembly Welding Straighten Integral machine:

1) Welding system:                    

  - SAW: Lincoln DC-1000 Twinarc SAW welding system (or China Huayuan made ZD7-1000IGBT PRO type SAW welding system, or China AOTAI)

 - Gas Shielded CO2 welding: Panasonic 500GL5, or HUAYUAN NB5

2) A.C. Variable Frequency drive system: Mitsubishi

3) Reducer:                                          Chinese-made

4) Hydraulic system:                            Chinese-made  

3. Technical features of ZHJ8020 H Beam Assembly Weld Straighten Integrated machine:

  As can be check from attached picture:

  1) Assembly: With the first step rough positioning of web and flange with the 3 sets of yellow-color manipulators

    (pulling rod system) deployed along the input conveyor, and the second step (precise) positioning of web and 

    flange with the alignment rollers at working unit, the H beam is assembled into shape;

  2) Welding: This set of ZHJ8020 Automated H Beam Assembly Weld Straighten Integral machine adopts with 

     SAW (Submerged arc welding). The welding power supply is Chinese HUAYUAN;

  3) Straightening: This unit is installed closely following assembly& welding units, and straighten the welded 

      flange with the downward straightening roller;

  4) Operation: The operating panel of this whole set of Automatic H Beam Fabrication machine is put together 

     with consoles of 2 sets of welding power supply, alongside column of machine gantry body. In this way, 

    operation of the H Beam Fabrication machine is easy and convenient. With the set up of welding parameters on

    its console, the entire working process of this automated H Beam Fabrication machine is highly effective and 

    fluent. Labor intensity is reduced to minimum;

  5) Application: With the above-mentioned strong points, this high efficiency H Beam Fabrication machine sees

       more and more demand in steel structure industry both in China and overseas.
