A. The Subject of this Page on Wuxi JACK H Beam Production Line:

1. This thematic page is for exploring technical strong points of Wuxi JACK Z15/ Z18/ Z20 T Beam H Beam Assembly and Tack Welding Machine, so that you can have a quick impression on this advanced product, which is applied as the first set of central machines in H Beam Production Line;

 

2. The Usage of T Beam H Beam Assembly and Tack Welding Machine:

1) Function: As its name suggest, this is an automatic running equipment for assembling steel strip plates into T Beam and H Beam, and strengthening the assembled workpieces by means of CO2 stitch welding (tack welding);
2) The banner of this page reflects a set of T Beam H Beam Assembly and Tack Welding Machine, at BOL (Beginning of line) at a Wuxi JACK exported to Russia HB1500 automatic H Beam Production Line;
3) Importance: This T Beam H Beam Assembly Machine is the first set of central equipment in H Beam Production Line, and the “most complicated” one in terms of mechanical structure and working logic: Its performance directly determines the integral output level of the entire H Beam Production Line;

4) Assembling and CO2 Tack Welding in Wuxi JACK T Beam H Beam Assembly Machine: (Fig.1)

C. Technical View on Wuxi JACK T Beam H Beam Assembly and Tack Welding Machine:

Slides 1: The Highly Reliable and Accurate Central Function of T Beam H Beam Assembly Machine:

1. The Two Main Functions in T Beam H Beam Assembly Machine are:

1) Assembly: Fitting up steel strips into T Beam and H Beam, making it central aligned in accurate position;
2) Stitch Welding: To prevent the assembled T Beam H Beam from falling apart, implement CO2 welding on the workpiece;
 

2. This slides elaborates on how does the Wuxi JACK T Beam H Beam Assembly and Tack Welding Machine completes the above two main functions in High Quality and Efficiency:

1) Assembly in the T Beam H Beam Assembly Machine:
 

a) There are 8 pairs of symmetric arranged alignment rollers which are used for pushing and securing the flanges and web into correct position;
b) To fully guarantee tight and firm clamping of workpiece, movement of these alignment rollers are driven with hydraulic oil cylinders, and guided with high precision bushings;
c) These alignment rollers are all eccentric type, which have ability of inching adjustment, delivering the most accurate fitting up in the T Beam H Beam Assembly Machine;

2) Stitch Welding in the T Beam H Beam Assembly and Tack Welding Machine:

a) As shown this slides, in one set of the T Beam H Beam Assembly Machine, there are 2 sets of CO2 welding torch in 45° mirror installation, for welding the 2 seams at the same time;
b) The position of these 2 welding torches can be adjusted precisely, based on specification of fabricated H Beam, by means of handwheels and precise linear guiderails on cross slides at its back side.

Slides 2: The Powerful Function Supporting Elements in Wuxi JACK T Beam H Beam Assembly and Tack Welding Machine:

The successful completion of central tasks can not be fulfilled without the support from function assistant elements. And this slides is for discussing this topic:
 

1. Hydraulic System in T Beam H Beam Assembly Machine:

1) As mentioned previously, to guarantee sufficient driving force, the fitting up of flange and web in the T Beam H Beam Assembly Machine is driven with hydraulic oil cylinders;
2) Hydraulic system has its independent oil pump station, which has good radiation;
3) Fine filters on oil pump station makes sure long term reliable working of electro-magnetic valves, which are critical working elements in hydraulic system of the T Beam H Beam Assembly Machine;
 

2. PLC Control in T Beam H Beam Assembly Machine:

1) T Beam H Beam Assembly Machine is the only equipment in H Beam Production Line, which has its electric control system equipped with PLC (Programmable logic controller), due to relative complicated control logic;
2) With the control of PLC, the length of stich welding seam and interval can be set up by customers, based on process technology requirement of T Beam H Beam fabrication in H Beam Production Line;

 

3. Inverter Control on Working Speed of the T Beam H Beam Assembly and Tack Welding Machine:

To have a precise and smooth management on Assembling/ Tack welding/ And sending forward of workpiece, working speed of this critical equipment in H Beam Production Line is controlled with A.C. inverter.

Slides 3: The 2 Stages Assembling in Wuxi JACK T Beam H Beam Assembly Machine:

1. This slides gives panorama view on the T Beam H Beam Assembly and Tack Welding Machine. Input conveyor is at its left back side;
2. As can be seen from its photo, considering the long length of workpieces and correspondingly assembling zone, the solitary precise assembling step discussed before is not sufficient to have a firm fitting up of flange with web;
 

3. For this reason, the T Beam H Beam Assembly Machine has double assurance mechanism of “2 Stages Assembling”:

1) Shown in the slides, there are 3 pairs of yellow color pulling rod boxes deployed in regular interval along input conveyor of the T Beam H Beam Assembly Machine, for preliminary positioning and clamping on flanges with web;
2) Same as the central zone precise alignment rollers, these pulling rod boxes are also driven with hydraulic oil cylinders, considering the necessary heavy and reliable driving force;

3) Hydraulic drive pulling rod boxes (Manipulators) in Wuxi JACK T Beam H Beam Assembly Machine: (Fig.2)

Slides 4: The Smooth and Precise Guiding of Downward Pressing Roller in Wuxi JACK T Beam H Beam Assembly and Tack Welding Machine:

1. As we know, during working of the T Beam H Beam Assembly and Tack Welding Machine, the workpiece T Beam H Beam is in the position of vertical orientation. So, its reliable and accurate positioning is of vital importance;
2. This job is performed by means of the overhead downward stroke pressing roller, which is installed on the U frame of the T Beam H Beam Assembly Machine, and moves downward for holding the workpieces firmly;
3. As shown in this slides, the downward movement of this pressing roller is also driven with hydraulic oil cylinders, and guided with precise linear guiderail, fully guaranteeing its reliable and smooth movement.
