Z15~Z20 Automatic H Beam Assembly Machine with Tack Welding

Background: The Automatic H Beam Assembly and Tack Weld Machine in the first photo was taken on an automatic Wuxi JACK HB series H Beam Production Line exported to East Europe.

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

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

2) Purpose: For producing semi-finished workpiece of welding H Beam: Assembled and tack welded. The next equipment following the H Beam Assembly Machine in the automatic H Beam Production Line is LHC H Beam Submerged Arc Welding Machine, as you can find from the first photo:

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) Requirement on Operator:  Less requirement on skill and experience of operator than manual H Beam Assembly Machine, so it is more easy to find eligible operators;

This is the reason nowadays Automatic H Beam Assembly Machine with tack welding takes more and more share in the field of H Beam production in Steel Structure industry.

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 Electric Control System of H Beam Assembly Machine:

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

PLC in electric control system of H Beam Assembly Machine: (Fig.4) 

b) PLC program controlling on H Beam fitting up is compiled on the basis of process technology of the H Beam Assembly and Tack Welding Machine:

Process technology flow of H Beam assembly in I Beam Assembly 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) Control Logic: 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) Upgrade Conveniently: 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) A.C. Inverter for Controlling Working Speed of H Beam Assembly Machine: (Fig.6)

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

b) Working Velocity Adjustment: There are eight sets of frequency are set in the A.C. 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) Single Cycle Working Mode: When this Automatic H Beam Assembly Machine works under Single Cycle or Auto Cycle, output frequency of A.C. inverter is controlled with PLC;

d) Manual Working Mode: 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) Process Parameters: A.C. inverter used in these Z15/Z18/Z20 Automatic H I Beam Assembly Machine has 0~400Hz output frequency range, 0.01Hz resolution, and consummate protection function;

f) Advantages: 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.
