Z15~Z20 Automatic H Beam Assembly Machine with Tack Welding

The Automatic H Beam Assembly and Tack Weld Machine in the first photo was taken on an automatic HB series H Beam Production Line exported to Russia.

1.     Application of Z15~ Z18 Automatic H Beam Assembly Machine:

1)      Z15~ Z20 is a product group covering Z15, Z18, and Z20 Automatic H Beam Assembly and Tack Welding Machine;

2)      For producing welding H Beam, the next equipment following it in the automatic H Beam Production Line is LHC H Beam Submerged Arc Welding Machine, as you can find from the first photo: (Fig.1) 

3)      This Z15~Z20 refers to product group of Automatic I Beam Assembly Machine with self alignment (Automatic assembly) and automatic CO₂ tack welding, realized in the fashion of two sets of CO₂ gas shielded welding power source, controlled with PLC and inverter in the control system of the H Beam Assembly Machine: (Fig.2,3) 

2.     Advantages of Automatic I Beam Assembly Machine:

As discussed in the previous section of Z15/Z18/Z20 manual H Beam Assembly Machine (synonym of welding H Beam Assembling machine), some of advantages with automatic machine are listed below but not limited to:

1)     Labor Cost Saving: Operation of the Automatic H Beam Assembling Machine involves only one operator instead of two operators in manual machine;

2)     Quality Assurance: Stable and consistent assembly and welding quality delivered compared with manual operation in the Automatic H Beam Assembly Machine;

3)     Less requirement on skill and experience of operator than manual H Beam Assembly Machine;

This is the reason nowadays Automatic H Beam Assembly Machine with tack welding takes more and more share in this H Beam production step.

3.     Electric Control System of Automatic H Beam Assembly Machine:

Electric system controls machine operation, and achieves automatic working mode. Below is brief on electric system of the Z15/Z18/Z20 Automatic H Beam Assembly and Tack Weld Machine:

1)     PLC in Control System of H Beam Assembly Machine:

a)       PLC is the core element of control system in the Automatic I Beam Assembly Machine: (Fig.4) 

b)      Its process flow is draft on the basis of process technology of the H Beam Assembly and Tack Welding Machine: (Fig.5) 

c)       PLC program is compiled on the basis of the above mentioned process flow in the automatic H Beam Assembly Machine;

d)      During work of the Automatic H Beam Assembling Machine, PLC sends out command in the form of digital signal, controlling function elements acts accordingly, fulfilling tasks of positioning H Beam web and flange, FOR/RVR of input and output drive conveyor, welding start, etc.;

e)      Change on H Beam Assembly Machine control logic involves only compiling PLC program, instead of reworking or replacing hard wired relay circuit. This is the most conspicuous merit with PLC;

2)     Inverter in Control system of H Beam Assembly Machine: (Fig.6)

a)       Main drive motor, input and output drive conveyor of the Automatic H Beam Assembly Machine are all controlled with inverter, in unified adjustable speed;

b)      Eight sets of frequency are set in the inverter ahead of time (preset), corresponding with eight segments of required motor revolve velocity for the Automatic H Beam Assembly and Tack Weld Machine;

c)       When this Automatic H Beam Assembly Machine works under Single Cycle or Auto Cycle, output frequency of inverter is controlled with PLC;

d)      When the Automatic H Beam Assembly Machine works under Manual mode, output frequency of the inverter is controlled with a DIP switch on the machine operating panel;

e)      Inverter used in these Z15/Z18/Z20 Automatic I Beam Assembly Machine has 0~400Hz output frequency range, 0.01Hz resolution, and consummate protection function;

f)        This makes sure that speed control of main drive and conveyor features in extensive range, smooth running and reliable work in the Automatic H Beam Assembly Machine.
