Overhang Beam Production Line Use LHC H Beam SAW Machine

As its name suggests, the LHC I Beam Gantry Welding Equipment is applied to be used in automatic H Beam Production line, as you can observe from the attached photos.  (Fig.1)

1.     Preparation Work for Installation of LHC Column H Beam Welding Machine:

As closure of introduction on LHC model H Beam Gantry Welding Machine for H Beam submerged arc welding, there are some points for attention for its installation, usage and maintenance (This is true for the LHA gantry type column I Beam SAW Machine, and LHT T type I Beam Submerged Arc Welding Machine also):

1)     Workshop Electricity Power Specification for LHC Column I Beam SAW Machine:

For maintaining good quality SAW of the LHC column H Beam Welding Machine, the electricity utility in workshop should meet the requirement of:

a)       Voltage fluctuation under rated frequency should be equal to or less than ±10%;

b)      Frequency fluctuation under rated voltage should be equal to or less than ±2%;

2)    Machine Foundation and Installation for LHC H Beam Gantry Welding Machine:

a)       We provide foundation drawing for the LHA gantry type, LHT T style, and LHC column style H Beam Welding Machine;

b)      For such kind of SAW H Beam Gantry Welding Machine, reliable and firm fitness of the rail for trolley travel is very important. They should be secured onto workshop floor with anchor bolts;

3)    Check Points for Machine Installation and Assembly of the LHC Column I Beam Submerged Arc Welding Machine:

a)      Make sure rail joints are located on the lining boards of machine foundation. Adjust level and distance between rails, no clearance between joints: (Fig.2) 

b)      Levelness of rail on the trolley platform should be kept within≤0.5mm for the whole length of the LHC Column H Beam Welding Machine;

c)      Adjust clearance of rail joints at transverse carriage, welding arm and moving trolley, making clearance between eccentric rollers and rail equal to and or less than 0.3mm，with flexible motion of no blockage;

d)      Adjust clearance between rail of floating unit and cross-slides, making it flexible and with no looseness. Then adjust spring pressure on the floating unit to proper tightness;

e)      Adjust clearance between the two pairs of eccentric rollers and traveling rail of the LHC H Beam Welding Machine, guaranteeing flexible travel of trolley, no blockage or crawling.

2.     Put into Operation of LHC Column H Beam Welding Machine:

1)      Consumables of the LHC Column I Beam SAW Machine:

a)     For these LHC H Beam Gantry Welding Machine (As well as LHT and LHA gantry H Beam Welding Machine), during its daily operation, there are two kinds of consumables of high volume consumption:

       i.           Welding flux of the SAW process;

      ii.           Welding wire --- For submerged arc welding, it is solid wire of size φ3.2～φ5mm; 

b)     For wire spool replacement and welding flux replenish in the LHC I Beam Gantry Welding Equipment, please drive the welding arm transversely to the location close to column, and perform the replace work on the platform. (This is for the purpose of keep balance of this Column I Beam Submerged Arc Welding Machine to the best degree): (Fig.3)

2)      All the above-mentioned is very important for precise management of the SAW LHC H Beam Gantry Welding Machine with stable performance;
