Used for produce diameter of 60mm carbon steel and alloy steel pipe
hot induction tube expander
The total distance of the tube expander is 10-14.5 meters. The
feeding and unloading mechanism of the tube expander adopts rollers
to drive the steel tube forward to finish feeding.If power supply
is installed in the front end of the tube expander, if coil is
placed on the adjustment rack of if coil, the core reamer mold is
put in place, the original tube is put in, the water pump and if
power supply are turned on, and if power is adjusted, the core of
the tube can be adjusted
Mould and tube heating.Start the tube machine again, you can
officially expand the tube.The intermediate frequency coil,
compensation resonant capacitor, reactor and other components of
the tube expander need to be cooled by circulating water.The
electrical control part of the tube expanding machine is installed
in the electric control box, and the travel switch is installed at
both ends of the tube expanding machine.
Special equipment for steel tube hot hole enlargement, mainly for
domestic large diameter steel pipe production cannot meet the
demand of market and all kinds of steel pipe specification is not
complete, meet the needs of small batch more varieties of steel
pipe production, can satisfy the different material steel pipe hole
enlargement and various non-standard steel tube expanding needs, is
currently the main production process of large diameter steel
pipe.It has been widely used in military industry, power plant
construction, aerospace industry and Marine industry equipment
manufacturing industry, making a great contribution to China's
steel pipe industry and energy construction.
The equipment is used in the production of seamless steel pipe,
straight seam welded pipe, coil pipe and so on.Expandable steel
tube varieties are: various carbon steel, alloy steel, stainless
steel and so on.
The expanding equipment mainly includes: the frame, the main oil
cylinder support plate (including the main oil cylinder), the
movable push plate, the front support plate, the automatic feeding
mechanism, the discharging roller table, the mold support, the
intermediate frequency coil adjustment frame (including the
intermediate frequency heating coil), the intermediate frequency
power supply, the electrical control system and so on.

Work flow of tube expanding machine
When expanding the pipe of the expanding machine, the movement of
the pipe adopts the translation mode, which is stable and accurate
and does not damage the pipe.This machine adopts the heating mode
of hot air circulation and is double-heating, and each heating
furnace is equipped with multi-grade heating furnace core.The
forming method adopts the qualitative method of shaping the inside
of the reaming head and adding external pressure, and the size of
the tube mouth is accurate. The machine is equipped with the
transfer switch of expanding solvent-based socket (straight port)
and expanding elastic seal ring type socket socket (R port) on the
control panel.And the R mouth is divided into the way of rising
block first and rising block after rising.The choice of tube
expanding mode is very convenient and the process is adaptable.
