The attached is a set of PHJ20 General Purpose 3 in 1 I H Beam Fabrication Machine working on site

A. Usage and Put in Work of PHJ20 I H Beam Fabrication Machine on Site:

1. Finished Workpiece from PHJ Series 3 in 1 I H Beam Welding Machine:

1) Output: PHJ20 I H Beam Assembly Weld Straighten Integral Machine produces welding H Beam/ I Beam/ T Beam of symmetric and asymmetric section shape steel structure members with max. height up to 2,000mm;

2) The below sketch shows illustration of workpiece made with the PHJ model 3 in 1 I H Beam Welding Machine;

3) Welding Mode: It adopts welding mode of SAW--- Submerged arc welding. It is widely used in steel structure facilities because of its wide versatility:

2. Operating on PHJ20 Model 3 in 1 SAW I H Beam Welding Equipment:

1) Raw Materials: As can be seen from the 1^st photo, there is a heap of its raw materials (The long strip steel plates cut from CNC Strip Plate Cutting Machine) cumulated right next to the input conveyor of this Automatic H Beam Manufacture Machine. And a piece of strip plate was being put on the input conveyor, which would be taken as flange of workpiece;

2) The operating station of this 3 in 1 I H Beam Welding Equipment is at the right hand of its main body, please check the 2^nd photo;

 3) It is composed of the operating panel of the 3 in 1 I H Beam Fabrication Machine, and the 2 control consoles of the SAW power supply;

4) Operating Way: On the control console, welding current/ voltage/ wire feeding speed of the SAW I H Beam Welding Equipment can be adjusted before working, and observed during working;

3. Supplementary Welding Units in 3 in 1 I H Beam Fabrication Machine:

The welding support unit of the I H Beam Fabrication Machine: 

1) Sintered SAW welding flux recovery unit;

2) SAW welding flux hopper;

3) Diameter 3.2mm to 4.0mm SAW welding wire feeder;

4) SAW welding wire spool;...

 Are installed on themain body of the 3 in 1 I H Beam Fabrication Machine;

Sometimes customer have their welding wire spool put on the ground, as is shown in the 3^rd photo. The function units of the Automatic SAW H Beam Welding Machine (I H Beam Welding Machine), including control board/ pump station/ SAW welding power supplies, are put on the workshop ground close to machine main body. As is shown in the 1^st photo.

B. Technical View on PHJ20 Automatic SAW I H Beam Welding Machine:

1.  Central Working Zone of 3 in 1 I H Beam Fabrication Machine:

 1) The 4^th photo shows central working area of the 3 in 1 I H Beam Welding Machine;

2) It was taken at assembling side (Workpiece flowing in side);

3) In the order of installation are assembling unit/ welding unit/ straightening unit of the PHJ15 I H Beam Assembly Weld Straighten Integral Machine;

2. Assembly Unit of 3 in 1 I H Beam Assembly Weld Straighten Integral Machine: 

1) The assembling unit is for fitting flange and web into the shape of “┷” (When making T Beam) or “工” (When making H Beam/ I Beam);

2) The fitting up flanges and web is realized by means of totally 6 pairs of rollers:

--- 3 pairs for clamping web (High up);

--- And 3 pairs for clamping flange (Low position);

3) The driving of these rollers in the 3 in 1 I H Beam Welding Equipment, as can be seen in the 4^th photo, are made with guiding brackets and bushings, which, for the flange alignment rollers, the left side is driven with manual leadscrew, and the right side is driven with hydraulic cylinders; 

4) The driving way for web alignment rollers are reversed with that of the flange alignment rollers;

3. SAW Welding Torches of PHJ 3 in 1 I H Beam Welding Machine:

1) The 2 sets of SAW welding torches are execution mechanism for welding operation in the I H Beam Welding Machine (I H Beam Fabrication Machine), which are controlled with SAW power supplies for its critical parameters of welding current and voltage;

2) Its operation is assisted supporting units of flux recovery unit and wire feeder;

3) The position of the welding torch can be precisely managed by means of cross slides and 45° gliding bracket, to aim at welding seam all the time during welding;

4. Straightening Unit in 3 in 1 I H Beam Fabrication Machine:

1) The straightening unit of the 3 in 1 SAW I H Beam Welding Equipment can be checked in the 5^th photo;

2) It utilizes the principle of three points squeezing, which, during passing through of the H Beam/ T Beam through the I H Beam Fabrication Machine, exert force onto the flange by means of the two pieces of downward straightening rollers (Driven with hydraulic cylinder), thus making the workpiece sent out of this Automatic H Beam Manufacture Machine in straight surface;

3) To adapt to varying flange width of the workpiece to be fabricated in I H Beam Fabrication Machine, the span of the two straightening rollers can be adjusted by means of handwheels, which is shown in the 5^th photo;

5. Wuxi JACK Batch Production on 3 in 1 I H Beam Welding Machine:

1) The 6^th photo shows WIP (Work in process) area of Wuxi JACK I H Beam Assembly Weld Straighten Integral Machine;

2) Due to its extensive applicability and large selling volume, the PHJ15 SAW I H Beam Welding Equipment are always made in volume production.
