H Beam Straightening Machine , H Beam Welding Line Integrated Machine
1. Machine introduction
PHJ series H beam
fabrication machine is a highly efficient equipment for
manufacturing welding structure H beam, which can finish the job of
accurate “I” shape assembly, SAW, flange straightening of light
duty H beam with the weld toe below 8mm.This equipment has the
merit of compact appearance while integrating the function of
assembly, welding and straightening, so as to leaving out transfer
of work-piece among different process, which is a cost efficient
equipment of good technology.
2. Technical parameters
● Work-piece dimension
No. | Parameters | PHJ15 |
1 | Flange thickness | 6-32mm |
2 | Flange width | 180-800mm |
3 | Web thickness | 6-25mm |
4 | Web width | 200-1500mm |
5 | H-beam length | 4000-15000mm |
● Machine parameters
- Welding: twin arc tack SAW
- Maximum weld toe size of single pass: 8mm
- Input conveyor: total length 10m, into 3 segments, of which one
is motor-driven 3 sets conveyor
- Output conveyor: total length around 10m, of which two can be
elevated 4 sets conveyor
- Assembly, welding and straightening speed: 0.2-2m/min
- Total power: 11KW (two welding power is 180KVA)
- Machine size: length × width × height = 28m × 4m × 4.2m
- Color: depend on customer demand
2. Assembly unit
There are 3 sets of
manipulator among input conveyors of the equipment, for rough
aligning and positioning of flange and web. When sheets are hoisted
onto the equipment, these manipulators can support the sheets and
align them, preventing the sheets from dumping, making operation
safe and reliable.
There are 2 sets of positioning units for flange and web each, with the positioning style of one side lead-screw, the other side hydraulic cylinder, making accurate positioning of the work-piece. The lead-screw positioning units (2 for flange, 2 for web) are joint together thru coupling shaft of reducer, guaranteeing in-phase working of the units, as well as simple and quick adjustment for different size of H-beam.
After web and flange are
sent into the equipment, the tail aligning unit will be raised
automatically, making sure alignment of face of flanges and web.
3. Welding unit
2 sets of U.S. LINCOLN
DC1000 SAW system is used for welding the 2 seams alongside both
sides of H-beam, of Twin arc fashion(TWIN, Ø1.6 wire), featuring in
high efficiency and good quality.
Position of welding torch can be adjusted and observed easily
during welding.
2 sets of automatic flux
recycling system are used for conveying flux to the welding seam
and screening and recycling un-sintered flux by way of the suction
hole at the rear side of torch, and sucking the flux back into flux
barrel for re-use.
5. Straightening unit
Deformation happens at the flanges post welding. For this reason, 1 set of flange straightening unit is equiped at the output side of the equipment. It is mechanic down stroke style, of strong force and easy control.
Thickness of flange that can be straightened see below table (tensile strength σb≈400MPa):
Flange thickness (mm) | 6-12 | 12-18 | 18-22 | 22-26 | 26-32 |
Flange width (mm) | 180-800 | 450-800 | 580-800 | 650-800 | 720-800 |
After welding, one side
of web will be subjected to heat input, making H-beam expanding and
bending upward. For this reason, 2 sets of elevating conveyor are
used for supporting H-beam.
The equipment has the same speed for assembly, welding and
straightening which is VF controlled and displayed in digit,
adapting to manufacture of H-beam of various specification.
