LHC Column Type Automatic H Beam Submerged Arc Welding Machine

1.     Working Manner of LHC Column H Beam SAW Welding Machine in Automatic Line:

Working as one of the core equipment in an automatic H Beam production line, the LHC product is a typical automatic Column I Beam Submerged Arc Welding Machine (I Beam is synonym of H Beam) in terms of:

1)     Machine control and operation;

2)     Workpiece H Beam feeding in, flipping and sending out;

3)     Linkage control with other H Beam Production machine in the line.

2.     Uniqueness of LHC Column H Beam Gantry Welding Machine:

Sharing the same SAW (Submerged arc welding) working principle and equipment with LHT and LHA gantry type H Beam Gantry Welding Machine, the LHC Column H Beam Welding Machine has its obvious uniqueness on the aspect of:

1)      Body structure --- The one side working overhanging trolley compared with double side working gantry frame in LHT and LHA H Beam Gantry Welding Machine: (Fig.1) 

2)      Quantity of welding unit --- One set in LHC versus two sets in the case of LHA and LHT T type H Beam Welding Machine);

3)      Therefore Productivity --- One piece of H Beam one time welded from LHC Column H Beam Gantry Welding Machine compared with two piece a time in LHA and LHT H Beam SAW Welding Machine.

3.     Technical Aspect of LHC Column H Beam Welding Machine:

Supplement on LHC Column H Beam Gantry Welding Machine:

1)     Control board of the LHC column H Beam SAW Welding Machine:

It is put inside column of the traveling trolley, which means it is invisible from outside. This is different from LHA and LHT H Beam Gantry Welding Machine. Such kind of design can make machine body of LHC H Beam Welding Machine has plain, open and shut structure: (Fig.2) 

2)     Rail span of LHC Column H Beam Welding Machine:

This specification in LHC is far less than in LHA and LHT H Beam SAW Welding Machine: 1150mm of LHC column H Beam Gantry Welding Machine compared with 4000~ 5500mm in LHA and LHT. This is determined by specialty of its body structure;

3)     Rail length of a set of standard LHC I Beam Submerged Arc Welding Machine:

a)       In LHC Column H Beam Welding Machine, It is 3m shorter than IN LHA and LHT (15m in LHC versus 18m in LHA and LHT H Beam SAW Welding Machine), and hence finished H Beam length produced shorter(12m versus 15m);

b)      Of course, this specification can be special made;

4)     Linkage Control of LHC Column H Beam SAW Welding Machine:

a)       Interlock with 90° /180° Overturning rack and steel conveyor at the front of and back of each set of LHC Column H Beam Welding Machine is made with pushbuttons and switches integrated on its operating panel (LHC); 

(Fig.3)

b)      This means, working as part of an automatic H Beam Production line, LHC H Beam Gantry Welding Machine not only has function of control itself, but also that of auxiliary equipment of the line;

4.     Welding Arc Tracing Unit Applied in LHC Column H Beam Welding Machine: 

(Fig.4)

1)      This is designed and made by Wuxi JACK ourselves. It is a detecting and tracing unit for managing welding process in the I Beam Submerged Arc Welding Machine;

2)      This unit is mechanical type, for controlling movement of welding torch in three axis(X, Y, Z). Please check the above picture on its structure;

3)      Motion control in Arc Tracing unit of H Beam SAW Welding Machine:

a)       The vertical direction is pneumatic type (driven with air cylinder);

b)      Horizontal and revolving direction is floating type;

4)      This unit makes welding torch of the H Beam Gantry Welding Machine aiming at welding seam throughout the entire welding process:

a)       When welding seam deflects leftward or rightward, the arc tracing rack will adjust automatically along the transverse carriage of the H Beam SAW Welding Machine under action of spring;

b)      When welding seam deflects up and down, control roller will adjust welding torch along vertical direction by means of air cylinder.
