Automatic Production Steel Structure H Beam Machine for Fabrication

A. The Task and Finished Product of Automatic Production Steel Structure H Beam Machine:

1. Just as its name suggests, this Steel Structure H Beam Machine is used for output welding H Beam/ T Beam with the conventional dimensions of:

1) Height (Web) is from 200mm to 1500mm/ 1800mm/ 2000mm;

2) Width (Flanges) is from 200mm to 800mm;

3) Wall thickness (Flange and web) is from 6mm to 40mm;

2. Wuxi JACK Competitive Edge on Automatic H Beam Production Machine:

1) You can even make cross section of H Beam/ T Beam in asymmetric structure with Wuxi JACK H Beam Fabrication Machine, as shown in below sketch: (Fig.1)

2) The finished product: Welding T Beam delivered from Wuxi JACK 3 in 1 Steel Structure H Beam Machine: (Fig.2)

2) The finished working parts: Welding H Beam delivered from Wuxi JACK Integral Function H Beam Welding Machine: (Fig.3)

B. The Function and General Working Steps in PHJ and ZHJ series 3 in 1 Automatic H Beam Production Machine:

To produce finished product of welding H Beam/ T Beam from strip plates, 3 major steps need to be completed in sequence:

1. The First Step: Assembling in the PHJ and ZHJ H Beam Assembly Welding Straightening Integral Machine:

1) Function: This step completes fitting up 2 pieces of flange and 1 piece of web into the constructure of H Beam;

2) Acting Sequence: The fitting up of flanges with web involves action of: Working parts positioning Alignment → Clamping, which needs heavy force of hydraulic drive;

3) Working Manner: Considering the long length of raw materials (Flange and web) and relative long time for its feeding in and assembly, which should be reliable and accurate, there are 2 stages of assembling in this H Beam Fabrication Machine:

a) The first stage: Hydraulic Manipulators deployed at input conveyor of the Three in One H Beam Fabrication Machine: (Fig.4)

b) The second stage: Hydraulic drive 6 pairs of alignment rollers at central zone of the Steel Structure H Beam Machine: (Fig.5)

4) Role Playing: This assembling step in H Beam Assembly Welding Straightening Integral Machine is counterpart of Z15/18/20 H Beam Assembly and Tack Welding Machine, but remove the CO₂ tack welding step, contributing outstanding cost down brough along with the PHJ&ZHJ H Beam Fabrication Machine;

2. The Second Step: Welding in the H Beam Assembly Welding Straightening Integral Machine:

1) Task: In this step, 2 pieces of mirror arranged welding torches implement finished welding on both sides of workpiece;

2) Importance: This step determines welding seam quality of finished product. This is the why this Steel Structure H Beam Machine is often called “Integral Function H Beam Welding Machine”;

3) Welding Mode in the PHJ and ZHJ Series Integral Function H Beam Welding Machine:

a) Majority SAW: Most of the welding is in the form of SAW (Submerged arc welding), which accounts for over 95% in application of the 3 in 1 Automatic H Beam Production Machine;

b) Sometimes GMAW: In minority conditions, to produce small size and thickness H Beam, such as web has thin wall of 6~10mm only, large current SAW is not applicable. By this time, you should make choice on GMAW CO₂ gas shielded welding in this Automatic H Beam Production Machine instead;

4) Role Playing of Welding in PHJ and ZHJ H Beam Assembly Welding Straightening Integral Machine:

a) Welding cell in 3 in 1 Steel Structure H Beam Machine is counterpart of LHA and LHT&LHC series H Beam Welding Machine;

b) The difference is, in LHA/ LHT/LHC series H Beam Welding Machine, welding torch moves back and forth several times to deliver large size welding seam;

c) While in this PHJ and ZHJ Integral Function H Beam Welding Machine, welding torch only performs one pass welding. This is the reason why PHJ and ZHJ series Steel Structure H Beam Machine only produces small to medium duty H Beam, with welding seam not exceeding 12mm;

d) Welding torch distribution and operation in Wuxi JACK Automatic Production Steel Structure H Beam Machine: (Fig.6)

3. The Third Step: Straightening in the H Beam Assembly Welding Straightening Integral Machine:

1) Task: In this step, the upper and lower pieces of flange will be flattened out to eliminate the deformation made from heat deformation;

2) Role Play: This unit finishes the task of HYJ&YTJ series H Beam Flange Straightening Machine;

3) Wuxi JACK Competitive Edge: The straightening capacity of Wuxi JACK H Beam Fabrication Machine is 40mm, compared with only 20mm by competitors;

4) Straightening system and its operation in Wuxi JACK Automatic Production Steel Structure H Beam Machine: (Fig.7)
