Sch80Medium Frequency Large Caliber Alloy Steel Pipe Pipe Expanding
Machine
I.Pipe Expanding Machine Features:
The patent product set cone die hole enlargement technology, medium
frequency induction heating technology, hydraulic technology in
one, with its reasonable technology, low construction investment,
wide range of raw materials and products specifications
suitability, flexible variable low input of production batch
adaptability to replace the traditional steel pipe industry tension
dial hole enlargement technology, became the resolve the shortage
of large diameter seamless pipe at home and abroad, a series of
large and medium diameter welded pipe specification is difficult to
complete an important and indispensable production capacity.
II. Pipe Expanding Machine advantages: intelligent constant
temperature system
1, the intelligent control of intermediate frequency power supply
at the time of expanding production will steel tube heated to the
required temperature and constant, effectively avoid the human
factors caused by the steel tube burnt (high temperature) to
produce the scrap quality decline and die for steel tube, at the
same time avoid the low temperature and the thermal expansion unit
thrust lever or die fracture is caused by the rising, to eliminate
the unsafe factors.
2. Compared with manual operation, heating the steel pipe is
energy-saving and environmental friendly, which simplifies the
operation procedure and reduces the labor cost, and enables one
operator to monitor the normal production of 10 pipe expanding
units at most at the same time
3, each unit set up two temperature measuring point intelligent
automatic temperature control, according to the different type of
preset steel pipe heating temperature, choice for expanding tube
heating and constant temperature, and the real-time display and
record, can print and save heating temperature parameters in real
time curve and history curve, which guarantees the traceability
data.

Iv. Pipe Expanding Machine composition
The equipment mainly consists of: machine stand, main oil cylinder
support plate (including main oil cylinder), movable push plate,
front support plate, automatic feeding mechanism, feeding roller
table, die bracket, intermediate frequency coil adjusting frame
(including intermediate frequency heating coil), intermediate
frequency power supply, electrical control system, etc.
First of all, the operation of the pipe expanding machine needs:
the pipe expanding machine has enough smooth operation space.
Before the operation of the pipe expanding machine, check whether
the surface of the power supply route is damaged, and then proceed
to the next process after confirming normal.
Select core bars, core heads and heaters according to the diameter
and thickness of the processed pipe and install them in order.
It is not allowed to fuel the material between the pipe and the
pipe mold, clear the dirt in the pipe, uniformly coated with lead
powder in the pipe.
The parts should be clamped, the steel tube and heater concentric
alignment.
Adjust the process parameters, turn on the power supply in order to
run the production.
During operation, please pay attention to check the temperature,
speed, size and surface quality of steel tube.
After the pipe expanding and pushing is completed, the machine is
in the state of waiting for production. The power should be turned
off, and the machine and surrounding environment should be cleaned,
and daily maintenance should be done.
The pipe expanding machine mainly includes: the frame, the main oil
cylinder support plate, the oil cylinder, the movable push plate,
the front support plate, the automatic feeding structure, the
feeding roller table, the mold support, the medium frequency coil
adjusting frame and the medium frequency heating coil, the medium
frequency power supply, the electrical control system and so on.
The pipe expanding machine is used in the production of thermal
expanding head and expanding pipe of seamless steel pipe, straight
seam steel pipe, straight seam welded pipe, coil pipe, etc.The
varieties to be expanded are: carbon steel, alloy steel, stainless
steel and so on.
We interchanged and enlarge head machines have advanced technology,
according to customer's specific requirements for each customer to
produce different models of expanding machine and hydraulic
pressure two-step expansion head machine, pipe equipment for
customers, ensure that customers in the market at a low price to
buy satisfaction of pipe equipment, for each customer to set foot
on the road of entrepreneurship, complete your wealth dream.
