CNC POLE SHUT- WELDING MACHINE,
Model: HM2500/13000
Designed for Monopole, highmast pole, 5G communication pole
Diameter range:500~2500mm, Thickness:normally , 6~20mm,
Length:13000mm
Note: the machine also can do more thickness, if thickness 18~25mm,
suggestion process : do first shut welding , then do surface
welding.
double arc three wire welding machine
Scope of application: suitable for large length medium size pole
longitudinal automatic closing welding, like 5G pole, monopole,
highmast pole
CNC POLE SHUT-WELDING MACHINE , it is suitable for one shell or two
shell type polygonal and circle taper pole(Conical pole). it is
automatic welding line, the gantry type structure is fixed and with
welding system, V-shaped fully pole length dolly(worktable) with
servo motor for speed adjustable moving , The hydraulic cylinder
push the clamping wheel to close the pole and do welding at same
time.
For two seam pole, when first seam welding finished, the bottom
roller will rise and rotate the pole to another seam position to
start second seam welding.
Proprietary features:
1.CNC automatic adjustment, CNC system, with the change of pole
diameter, automatically adjust the pressure, automatically adjust
the presser foot position, automatically match the feeding speed
and position, keep the welding seam always in the closed state, to
ensure the smooth welding.
2.Special CNC control system makes the left and right side of the
foot synchronization performance is very good
3.On the basis of the qualification of the previous process, after
welding, there is no torsion of the pole weld, and there is no need
for personnel to pry and twist the rod at the back of the machine
to center the weld.
4.The pole is on the V-shaped worktable, and its motion is servo
controlled to ensure the stability of head and tail welding.
Welding from head to tail greatly reduces the length of the tail
that is not welded.
5.The number of clamping roller is 3 sets, the advantage is reduce
the roller pressure to the pole surface , and reduce the scratch on
the surface . It is suitable for the production of octagonal pole,
polygonal pole and conical pole. It can be equal diameter or
conical.
6.The V-shaped worktable(dolly) with motorized fast returning back
function, and it reduces the labor intensity of operators.
7.Submerged arc welding function
8.With pole back guiding device,it can be adjusted adaptively. In
practical operation, the position of welding seam is seldom
adjusted, which reduces the labor intensity of operators.
9.Through the camera installed on the machine head, the welding
seam is reflected on the screen of main control panel, making the
tracking of the welding seam simple and easy, and reducing the
labor intensity of the operator for monitoring of the welding..
10.The self-developed oil pressure and CNC system, making the
welded pole round and deformation small.
11.For two seam pole, when first seam welding finished, the bottom
roller will rise and rotate the pole to another seam position to
start second seam welding
12.loading and unloading in the front position
13.The inner copper blocks, which greatly improves the welding
penetration rate. Copper block contains cooling water
14.Operator: 1 person.
15.Optional items:
15.1 for plate thickness greater than 10mm, adopt double arc and
double wire (or double electric and three wire) submerged arc
welding, DC + AC, DC welding adopts high current and low voltage,
DC arc obtains large penetration, AC adopts relatively small
current and high arc voltage, increases fusion width, and obtains
beautiful weld formation. Double the welding speed, improve the
weld performance and reduce the power consumption..
15.2networked system
Function: timely update the software to obtain the best and latest
software and experience data, which can assist customers in remote
fault diagnosis and remote parameter adjustment. It is convenient
for customers to quickly resume production.15.3Spare parts with
