POLES WELDING MACHINE
Adda Fer Meccanica has recently delivered two automatic poles welding machine for an important Mexican customer.
From 69 kV up to 400 kV, our customer manufacture a wide array of types and configurations, including single circuit, double circuit and overheadto-underground transitions, all with or without underbuilt circuit supports.
They routinely provide reliable solutions for complex base plate specifications, special crossarm requirements and multiple accessory configurations.
Over the years they have developed a well earned reputation in the challenging high-mast lighting pole sector, supplying poles in varying heights for diverse wind conditions and equipment requirements.
The machine is designed to process both poles in two shells or in one piece, in case of poles in two shells the machine after loading is able to assembly and process the long seam weld without tack weld.
- Max Thickness: 16 mm.
- Min Thickness: 3,2 mm.
- Max Outside Diameter at the Base: 1.900 mm.
- Min Outside Diameter at the Base: 600 mm.
- Max Finished Pole Length: 16.000 mm.
- Min Finished Pole Length: 6.000 mm.
- Max Pole Weight: 10.000 Kg.
- Welding Capacity: 1.250 A
- Positioning Carriage Speed: 0,3 - 2,0 m/min.
- Positioning Carriage Return Speed: 10 m/min.
• Loading system
It is composed by a fixed roller table with a “v” shape opened in the middle, able to support both the half shells or the poles in one piece. A series of tilting arm with rollers, allows the possibility to load the half shells by crane. After loading the shells can be handled by a remote control, to the correct position. Than the carriage by an hydraulic clamping device provide the feeding for welding. A series of mobile separators keep the two shells opened on the bottom.
• Positioning carriage
The carriage holds a clamping device controlled by a hydraulic cylinder, it is able to clamp both poles in one piece or in two pieces after loading, than move the pole from the loading position through the welding machine.
The carriage is driven by a servomotor with gearbox and pinion-rack system for the whole stroke.
This allow the possibility to program welding speed and pole positioning in automatic mode, or manually through a potentiometer.
After complete welding of the pole, if the pole is in one piece the carriage can return to its loading position by a fast return speed.
If the pole is composed in two shells, after the first welding the poles can be rotated 180° by a rotation device (not included) and then moved to the second welding machine.
