Horizontal H beam Production Line

This is a special line used to assemble and weld H beam. Compared with normal vertical line, it has the advantages of higher productivity and less deformation, and is suitable for producing light H beams. The line is composed of end assembly machine, front welding machine, overturning machine, back welding machine, and their conveying roller. This line can make H beam assembly, welding, overturning and transmission.

Main technical parameters

Suitable H beam section size:
Web height： 300-1500 mm
Web thickness： 4-16 mm
Flange width： 150-500 mm
Flange thickness： 5～20 mm
Suitable work piece length： 4000～15000 mm
Work piece maximum weight： 4000 kg
Cross section drift angle： ≤8°

Main technical feature

When assemble, just needed to do spot welding of H beam end, then can go into the welding process, welding machine will re-position the three plate, thus increase assemble speed.
Work piece is put horizontally (web is horizontal and flange is vertical), and beam will move during welding, and can weld two seam at the same time to reduce deformation caused by welding heat.
Machine is equipped with Lincoln DC-1000 welders, which used single arc twin wire welding mode, wire diameter is 1.6 mm, and welding speed can reach 1200 mm/m, the welding seams are well formed and look beautiful.
This line is more automatic then traditional ones, so can reduce the labor intensity, and reduce operator to 4-5
It is suitable to weld variable cross section H beam ≤8°

Technical illustrations

1.End assembly machine

End assembly machine is used to combine right plates to H shape, and then doing spot welding at plate end. End assembly machine is composed by main machine, conveying roller, hydraulic system and electrical control system.

Main machine is made up of web elevate device, end aligning device and conveying device, all of their motions are drive by hydraulic.

Roller is rotated by motor and reducer, thus conveys work piece to main machine. There are hydraulic tilt device on both sides of roller, which can turn and adsorb the flange plates to magnetic guide roller to form plates to H shape.

1.1 Main parameters

Conveying speed： 9.3 m/min
Roller motor power： 0.75×2 kW
Hydraulic station power： 5.5 kW

1.2 Supply range

One set of main machine
Conveying roller 3.4m * 4pcs
Tile device 2 sets (16pcs)
Hydraulic system: one set of station, cylinder and oil pipes
Electrical control system: one set of control box

1.3 Working process

Put one piece of web plate to middle of roller → put two pieces of flange plate to both sides of roller → roller conveys web and flange plates to main machine → flange tile device makes flanges vertically → tilt device reset → web elevating device raises web plate to right position → align end of three plates → manual spot welding of end → web elevating device falls → roller conveys work piece to welding machine

2. Front welding machine

3 (2)

The front welding machine combines mechanical, electrical, hydraulic and pneumatic technology into one body, it welds and forms the H beam.

2.1 Main feature

Welding speed： 0.3～1.9 m/min
Roller conveying speed： 9.3 m/min
Main motor power： 0.55 kWx2
Roller motor power： 0.75×4 kW
Flux recover power：3 kW×2
Hydraulic station power： 5.5 kW

2.2 Supply range

One set of main machine
One piece of assistant position device
Conveying roller 3.4m * 8pcs
Flux recovery system, which includes 2 sets of recover, tank, bucket, conveying pipe, and valve
SAW welder: 2 sets of Lincoln DC-1000
Hydraulic system: one set of pump, cylinder and oil pipes
Electrical control system: one set of control box

2.3 Working process

Roller sends the assembled H beam to assist position device → assist position device raises web plate → feed into welding main machine → flange clamp device of main machine clamps the flange plates → elevating device of main machine adjusts web height → side press device of main machine presses H beam flange plate → web press device of main machine presses the web plate → adjust position of welding torch → start flux convey switch → start flux recover switch → start welding → stop welding → cut flux convey switch → cut flux recover switch

3.Double 90°overturning machine

Double 90°overturning machine has three pieces, and is controlled by one individual hydraulic station and electrical control box. This machine is used to turn H beam in 180° after two seams are welded, in order to weld another two seams.

3.1 Main parameters

Overturning capacity: ≤ 5 T
Hydraulic station power: 15 kW
Hydraulic system working pressure: 16 MPa

3.2 Supply range

Overturning frame: one set (3 pieces)
Hydraulic system: one set of hydraulic station, cylinder, and pipes.
Electrical system: one set of electrical control box

3.3 Working process

Move H beam to overturning machine after front welding machine→front overturning machine turns H beam in 90°→back overturning machine turns H beam in 90°→send H beam to back welding machine by conveying roller

4. Back welding machine

The back welding machine combines mechanical, electrical, hydraulic and pneumatic technology into one body, it welds and forms the H beam.

4.1 Main feature

Welding speed： 0.3～1.9 m/min
Roller conveying speed： 9.3 m/min
Main motor power： 0.55 kWx2
Roller motor power： 0.75×4 kW
Flux recover power：3 kW×2
Hydraulic station power： 5.5 kW
