Symmetric Beam ZHJ18 Model 3 in 1 Vertical H Beam Welder Machine

A. Product Brief on ZHJ8018 Model 3 in 1 H Beam Fabrication Machine:

1.  Characteristic:

1)  ZHJ8018 is the medium model of ZHJ series symmetric welded H Beam production purpose Automatic 3 in 1 Vertical H Beam Welder Machine. The largest web height of welded H Beam fabricated from this model is 1800mm. Please check attached picture and below:

2) Wuxi JACK ZHJ18 model machine fabricates on T Beam, as commissioning process before painting: (Fig.1)

2. Major Working Steps in Sequence in 3 in 1 H Beam Welder Machine:

1) 3 Core Units: Checking from workpiece (Flange and web) incoming side, and in the direction of workpiece going forward, the three main working units in this machine is Assembly/ Welding/ Straightening units, which are installed and combined into an integral main body without dividing line;

2) Nomination: This is where the other name of the machine: 3 in 1 H Beam Assembly Weld Straighten Machine got from:

3) From top to bottom, 3 consecutive function units of: Assembly – Welding- Straightening, which work as an integral group but operate separately: (Fig.2)

3. Primary Process Technology of 3 in 1 H Beam Welding Machine:

1) Workpieces Feeding In: The raw materials for making welded H Beam in the machine: One piece of web and two pieces of flanges, which are long strip shaped steel plates, cut from CNC Strip Plate Cutting machine, are sent into the machine by way of its input conveyor roller tables 2 rounds:

The fabricated T Beam is hoisted onto input conveying roller table of the 3 in 1 H Beam Welder Machine: (Fig.3)

2) T Beam and H Beam 3 in 1 Fabrication: The flanges and web are assembled/ welded /straightened into finished T Beam/ H Beam, with one time pass through the machine: The first round into ┷ shape (T Beam), and the second round into 工 shape (H Beam), thus being processed into the final workpiece (welded H Beam). This is the other name of the machine: 3 in 1 H Beam Fabrication Machine got from:

3) Finished Workpiece (T Beam/ H Beam) Sent Out: At the completion of these steel structure parts manufacture, the welded T Beam/ H Beam will be conveyed out of the 3 in 1 H Beam Welder Machine. Considering heat effect on welded H Beam after SAW, the first segment of output conveying roller table has uplift function, which is driven with powerful hydraulic oil cylinders:

B. Technical Comparison on PHJ Versus ZHJ Series 3 in 1 Vertical H Beam Welder Machine:

1. We introduced Structure/ Main units/ Supporting units/ Welding Mode of PHJ and ZHJ series machine in previous sections of PHJ15, PHJ18, and ZHJ15 model machines, please check;

2. Comparison between PHJ and ZHJ Series Automatic 3 in 1 H Beam Welding Machine:

1) Primary Common: These two sub groups of machine share the basic same structure and working principle;

2) Differs in H Beam Assembly Section: The main difference lies in assembly unit of the machine:

This sketch gives one glimpse on difference between finished H Beam from PHJ and ZHJ machine: (Fig.6)

a) PHJ series machine has semi-automatic mode: One side of its assembling unit with hydraulic drive, and the other side with manual handwheel turning. This is for the purpose of acquiring outcome assembling on asymmetric cross section T Beam and H Beam:

b) ZHJ series machine has its both sides of assembling unit fully automatic running: H Beam are fit up under hydraulic driven in phase:

This gives the reason, why PHJ models machine can produce both symmetric and asymmetric welded H Beam and T Beam, while ZHJ series machine can only produce symmetric welded H Beam and T Beam, but in higher assembling efficiency.

C. Quality Control on PHJ and ZHJ Series 3 in 1 H Beam Assembly Weld Straighten Machine:

1. Overall View: Wuxi JACK has comprehensive quality managing system on all of our products, covering all aspect of quality control: 1^st operation, fabrication, heat treatment, assembly and performance test, coating and painting, contamination Control, etc., and has full time engineer to manage it;

2. Internal Process Control: We set up series of IPV (Internal Process Validation) for self inspection by operators on their jobs, and QG (Quality Gate) by inspectors, on the critical assembling line of our products, including PHJ and ZHJ series automatic 3 in 1 H Beam Fabrication Machine

3. After Sale Service Promise: We have full time customer service quality assurance engineer to deal with all the feedback issues from customers. If ever issues happened with our products, including PHJ and ZHJ series 3 in 1 H Beam Welding Machine, we give feedback within 4 hours upon reception of notice from customers. First is ECA (Emergent Corrective Action), then upon investigation, give customer on formal analysis report covering Root Cause Analysis and PCA (Permanent Corrective Action);

4. One of the core legacies of our company is CI (Continuous improvement). With years of experience on PHJ and ZHJ series SAW 3 in 1 H Beam Welder Machine, we maintain the always improved status of this widely applied equipment, making it rendering better service for customers.
