Z15 Self Alignment H Beam Assembly Machine with Automatic Tack Welding

Application and Working Site of Z15 I H Beam Assembly Machine:

Background: The Z15 model Automatic H Beam Assembly and Tack Welding Machine in the attached first photo was taken on an exported automatic I H Beam Production Line produced by Wuxi JACK.

1.  The Usage of Z15 Automatic H Beam Assembly Machine:

1) Application: Z15 model machine is the basic, indispensable, and the most widely used H Beam Production Machine;

2) Process Step: This machine initiates on the first step in the process of welding H Beam production:  

Process technology route of Wuxi JACK Z15 model automatic machine: (Fig.1)

a)  T Beam Assembly: Assembles one piece of flange and one piece of web into “ ┷” Beam, or inversed T Beam;

b) H Beam Assembly: Flip the assembled T Beam 180°, and assembles the second piece of flange, making the workpiece into a piece of H Beam;

3) “Complicated” Electric Logic Control in Automatic H Beam Assembly Machine:

Of all the three basic steps of H Beam Production: 

a) Z models H Beam Assembly Machine; 

b) LHC/ LHA/ LHT models H Beam Submerged Arc Welding Machine;

c) HYJ/ YTJ models H Beam Flange Straightening Machine, 

The H Beam Assembly Machine is the most complicated one in terms of logic control of machine working steps, which utilizes PLC (Programmable Logic Controller) as its core control unit;

4) Assembly Style of H Beam Assembly Machine:

As introduced in the product category of Z series H Beam Assembly Machine, on the aspect of alignment style of web and flange (Which in essence is assembling way of the machine), it has two types of:

a) Self alignment (Automatic control);

b) Manual alignment;

5) Characteristics of Z15 H Beam Assembly and Tack Welding Machine:

Z15 automatic control can be viewed as “Standard” model of H Beam Assembly Machine, because of below two factors:

a) Max. H Beam Web Height: One is because the max. allowable H Beam size of 1500mm web height produced from the Z15 model machine, is the most popular dimension of H Beam Production Machine in Steel Structure Industry;

b) Control Way: The second reason is working mode of automatic assembling and automatic CO₂ welding is the most preferred configuration by customers.

2.  Working Process Feature of Z15 Automatic H Beam Assembly and Tack Welding Machine:

2) Accurately assembling H Beam in Z15 model Self Alignment Machine: (Fig.3)

3) Assembly Style: In the automatic welding period of the Z15 model machine, when the H Beam is clamped with symmetrical arranged rollers driven with hydraulic unit, two sets of CO₂ welding power supply perform tack welding at both sides of H Beam simultaneously:

4) PLC Control: The whole process of workpiece Feeding, Assembly and Tack welding are all controlled with PLC in the electric control system of Z15 model I Beam Assembly Machine, featuring in good precision and high automation:

Welding torch motion is controlled with PLC in the machine: (Fig.6)

5) Process Parameters: Besides, the process control parameter of the machine, such as length of each segment of CO₂ welding seam, welding velocity, etc. can be modulated by editing program of the PLC, based on practical working site of this H Beam Production Machine;
