High Quality Z Series I Beam Assembly Machine with Spot Welding

1. Application of Z series Automatic H Beam Assembly Machine:

1) Background: The attached first photo represents typical application site of I Beam Assembly and Tack Welding Machine: Highly automatic H Beam Production Line;

2) Related H Beam Production Machine:

As you can find from the first photo, the other H Beam Production Machine following the H Beam Assembly Machine: 

a) 90° Steel Structure Overturning Rack;

b) LHC H Beam Submerged Arc Welding Machine.

2. Manual versus Automatic CO₂ Welding in Automatic I Beam Assembly Machine:

1) Advantage of Automatic CO₂ Welding in H Beam Assembly Machine:

a) Raising Productivity: For producing the same size of H Beam, Automatic I Beam Assembly and Tack Welding Machine has 15% higher producing efficiency than that of Manual models equipment;

b) Advantages of Automatic Mode for Running of H Beam Assembly Machine:

For these reasons, we recommend Automatic I Beam Assembling Machine to customer when they purchase this H Beam Production Machine, because of the below several reasons:

(1) Labor Cost Saving: One set of Automatic H Beam Assembly Machine needs only one operator to take care production process, instead of two operators in the manual H Beam Assembly Machine;

(2) More Easy to Find Eligible Operator: Requirement on operator capability in manual I Beam Assembly Machine is much more strict than operator of automatic equipment, in view of welding skill and experience;

(3) Quality Assurance: The H Beam Production Machine of Automatic H Beam Assembly Machine delivers finished H Beam with quality more stable and consistent than that of the manual equipment, so that less inspection work involved;

(4)  Flexible on Process Technology Upgrade: More flexible in terms of control logic of the Automatic I Beam Assembly and Tack Welding Machine: For future expansion or update, because of PLC soft control, instead of hard wired relay circuit;

In this sense, from customer point of view, the Automatic H Beam Assembly Machine can pay for itself more quickly than manual equipment;

2) Advantage of Manual CO₂ Welding in H Beam Assembly Machine: 

Operator work on CO₂ spot welding in H I Beam Assembly Machine: (Fig.4)

a) Better utilization rate on CO₂ welding power source: Customer can use the existing power sources of their own, instead of two sets of brand new as in the case of Automatic I Beam Assembling Machine;

b) Minimize Negative Affect of Mal-Operation: If there exists problem with PLC program, one batch of unqualified H Beam may have already been produced from automatic H Beam Assembly Machine, compared with possibly only one or two pieces in manual I Beam Assembly Machine: The loss is much less;

c) Single Mode First: This is the reason we suggest customer to have trial run in Single mode first before transferring to AUTO cycle, at initiation of H Beam Assembly Machine work.

3. Hydraulic System in I Beam Assembly and Tack Welding Machine:

1) Importance of Hydraulic System in H Beam Assembly Machine:

a) Working Principle: From the perspective of control and power, the Z15~Z20 H Beam Assembly Machine with Tack Welding is essentially controlled with electric PLC and A.C. inverter for its working logic management and speed control, and powered with hydraulic cylinder for its assembling job;

b) Importance: So, hydraulic system of the H Beam Production Machine I Beam Assembling Machine is of vital importance, as driving energy source of H Beam fitting up;

2) Composition of Hydraulic system in H Beam Assembly Machine:  

Hydraulic pump station of H Beam Assembly Machine: (Fig.5)

a) Composition: In H Beam Assembly Machine, hydraulic system is composed of pump station, cylinders and piping;

b) Functions: In Z15~Z20 H Beam Production Machine of I Beam Assembling Machine, downward pressing roller, web/ flange positioning and clamping unit, web/flange terminal alignment unit, pulling rod system, arc guiding unit are all controlled with hydraulic system;

c) Start Up Way: Downward pressing roller, alignment unit and arc guiding unit are all started with hydraulic cylinder directly;

d) Advantage: The hydraulic cylinder for driving the downward pressing roller has long stroke;

e) Extension Shaft: To cater for pressing down H Beam web of various specifications in the H Beam Assembly Machine, usually it is necessary to add an extension shaft at the front end of piston rod of the oil cylinder.
