|2||Suitable workpieces||The maximum diameter can reach 2300mm, and the maximum length can
1. This machine is a gantry type single-arm submerged arc welding
machine, which can be used to weld longitudinal seam and outer ring
seam of cylinder body (real-time adjustment of welding gun by
manual adjusting electric cross).
2. The machine is equipped with two lifting arms, which can be used
for electric lifting and transverse movement. One is equipped with
submerged arc welding head for submerged arc welding and the other
is used for submerged arc welding.
3. The machine is equipped with an automatic flux recovery machine,
which can recover the residual flux around the weld.
|4||Equipment composition||This machine is mainly composed of gantry frame (1 set), submerged
arc welding arm slide mechanism (1 set), submerged arc welding
lifting arm working platform (1 set), submerged arc welding machine
(1 set), electric cross fine tuning (1 set, submerged arc welding),
flux recovery machine (1 set) and electric control system (1 set).|
1. Gantry frame is the skeleton part of the machine. It bears all
the load of the equipment and is mainly responsible for the
vertical movement of the load.
2, the gantry rack is mainly composed of the left and right walking
mechanism, the upper platform and supporting columns. The left and
right walking mechanism is at the bottom of the gantry frame, and
the gantry frame is formed by connecting the supporting column with
the upper platform.
3. The left and right walking mechanism adopts double-motor reducer
to drive the two rollers synchronously to ensure the stable
operation of gantry frame. The gantry drive motor adopts frequency
converter to adjust speed to meet the speed requirement of
submerged arc welding process.
4. One side of gantry frame is provided with guide rail guide
wheel, which can effectively prevent gantry frame from derailing
during operation. Rubber collision blocks are arranged in front and
back of gantry frame to prevent the trolley from rushing out of the
guide rail under the condition of out of control due to limit and
5. A rectangular guide rail is machined on the front side of the
upper platform, and the sliding mechanism can slide freely across
the guide wheel. Auxiliary equipment for laying or installing wire
feeder, flux recovery machine, etc. on the platform.
The slide mechanism (1 set) of submerged arc welding arm and the
working platform (1 set) of submerged arc welding lifting arm all
contain the slide mechanism. The lift arm (or welding arm) of the
slide mechanism is mainly used to satisfy the transverse direction
of the accessories installed on the slide plate through the
transverse slide which can be transversely moved electronically in
front of the gantry frame. Demand for up and down movement.As
|7||submerged arc welding system|
1. There is only one set of submerged arc welding system in this
machine. The degree of welding torch deviation from the weld is
observed manually on the platform of lifting arm, and the deviation
of the welding torch is corrected manually by adjusting the
electric cross fine-tuning manually through the manual box, so as
to track the weld.
2. Submerged arc welding system consists of submerged arc welding
arm slide mechanism (1 set), submerged arc welding machine (1 set),
wire feeder (including welding gun, 1 set), electric cross fine
adjustment mechanism (1 set), wire pad (1 set), flux recovery
machine (1 set), welding control box (1 set).
3. Submerged arc welding arm slide mechanism is used for submerged
arc welding slide mechanism, which is equipped with electric cross
fine-tuning mechanism, wire feeder (with welding gun), flux tube,
flux hopper, etc.
4. The machine adopts Shanghai HUGONG MZ-1000 submerged arc welding
5. When submerged arc welding, adjust the sliding plate mechanism
of submerged arc welding arm and electric cross fine-tuning to
align the welding torch with the weld seam, adjust the upgraded
working platform to make the operator easy to observe, adjust the
welding current, power supply, the walking speed of the gantry,
etc., and then start the gantry, welding machine and recovery
machine for submerged arc welding.
|8||Layout of cables and routes||This machine has more cables to ensure beautiful, welding arm
(lifting arm) lifting using tow chain wiring, portal frame
longitudinal movement using pulley.|

tempering. The tooth surface is quenched and durable.
3. The guide wheel is made of 45 steel and quenched and tempered.
4. All shafts are made of 45 steel after quenching and tempering.
They are durable and reliable..
|10||Electronic control system|

electronic control box and the remote control box, each with a
panel, which is responsible for the control and remote control
2. The electronic control box is made up of CNC system, contactor,
relay, etc. The main key electrical components adopt well-known
