PHJ20 Fit Up Full H Beam Fabrication Machine for Heavy Industry

A. Applicable Workpiece of PHJ20 Fit Up Full H Beam Fabrication Machine:

1. Finished product of PHJ20 Automatic H Beam Welding Machine:

 Welding H Beam of:

1) Max. web height 2,000mm;

2) Cross section shape of finished H Beam: Both symmetric and asymmetric alignment of web respective to flanges;

3) Related product page: Attached picture on illustration of workpiece for PHJ and ZHJ series is demonstrated in H Beam Assembly Welding Straightening Integral Machine;

2. "Label": PHJ20 model 3 in 1 H Beam Welding Machine (H Beam Fabrication Machine) is the largest model among standard ones of its product group.

B. Configuration and Operation of PHJ20 Model 3 in 1 H Beam Welding Machine:

1. Configuration of the PHJ20 Model 3 in 1 H Beam Welding Machine:

1) We give brief introduction on:

a) Structure;

b) Working units: Assembly/ Welding/ Straightening;

c) supporting units: Input/ Output conveyor;

 d) Power units: Hydraulic station;

e) Control units of PHJ series Vertical H Beam Welder (H Beam Welding Machine) in the previous two product sections of PHJ15 H Beam Fabrication Machine and PHJ18 H Beam Fabrication Machine, please check;

2. Operation in the 3 in 1 H Beam Welding Machine:

1) As shown in the attached 6 pictures, operating panel of whole set of PHJ series Automatic H Beam Fabrication Equipment (H Beam Welding Machine) is put together with control consoles of its 2 sets of welding power supply, alongside column of machine gantry body;

2) In this way, operation of the H Beam Fabrication Machine is easy and convenient;

3) Strong Points: With the set up of welding parameters on control console of welding power supplies, the entire working process of PHJ series 3 in 1 H Beam Welding Machine is highly effective and fluent. Labor intensity is reduced to minimum;

3. Precondition on Proper Operation of PHJ series Vertical H Beam Welder (H Beam Welding Machine): 

Pay attention to relationship between flange thickness and width produced with PHJ series Automatic H Beam Welding Machine as below:

Thickness of flange that can be straightened see below table（tensile strength σb≈400MPa）：

C. Efficiency Raised with PHJ Series H Beam Fabrication Machine:

1. Working Speed Analysis: As introduced in produce section of H Beam Production Line, the working speed of H Beam Assembly Machine/ H Beam SAW Welding Machine, and H Beam Straightening Machine are:

Working Speed Comparison on 3 in 1 H Beam Welding Machine:

a) H Beam Assembly Machine for assembling and tack welding: 150 ~ 2,000 mm/min.;

b) H Beam SAW Welding Machine for submerged arc welding: 200 ~ 2,000 mm/min.;

c)  H Beam Straightening Machine: Based on specific model 6,000 / 9,000 /18,000 mm/min

2. Analysis on Working Speed of H Beam Fabrication Machine Versus H Beam Production Line: 

 1) Major Gap: We can see that there is large gap between working speed of assembling and welding with respect to straightening;

2) Which means, the conventional H Beam Straightening Machine have lots of time in idle condition, waiting for H Beam SAW Welding Machine completion operation;

3) The corresponded line balance is at worse condition for traditional H Beam Production Line than that of PHJ series 3 in 1 H Beam Welding Machine, which makes uniform speed of H Beam assembly/ welding and straightening;

4) Ideal Line Balance Rate Acquired from H Beam Fabrication Machine: This is the reason workshop installed with PHJ series Fit Up Full H Beam Fabrication Machine usually sees smooth running of manufacturing flow.
