Used for manufacturing of large diameter carbon steel pipe
expanding machine
The main components of the tube expanding machine include: stand,
main oil cylinder support plate, movable push plate, front support
plate, automatic feeding mechanism, discharging roller table, mold
support, intermediate frequency coil adjusting frame, (including
intermediate frequency heating coil) intermediate frequency power
supply, electrical control system.
Operating process of the expanding machine: the rinsed pipe is sent
to the rotary idler device on the center line of the expanding
machine.Using this rotating idler device, combined with the camera
system, the tube weld is precisely rotated to the 12 o 'clock
position to ensure that the weld can enter the groove of the upper
sector of the tool during subsequent diameter enlargement.The
lifting cone roller way lifts the pipe to the center line of the
reaming machine and the position is controlled by the displacement
sensor in the lifting hydraulic cylinder.The clamping trolley moves
forward and is controlled by a metal detector to detect the end of
the tube and to secure it. At the same time, a signal is sent to
start the feeding roller of the clamping trolley. The position is
controlled by an encoder.The pipe length is combined with the
reaming head to automatically calculate the optimal reaming
steps.The clamp jaws can be rotated to avoid damaging the tube
wall.During the advance, the height of the clamp can be adjusted to
compensate for the pipe straightening deviation and optimize the
straightening effect of the reamer.

Compared with manual heating of steel pipe, the intermediate
frequency tube expander simplifies the process and reduces labor
cost and time.Increased production efficiency.
The equipment consists of the main engine of the hydraulic pusher,
the automatic feeding and discharging mechanism, the hydraulic pump
station, the tube adjusting device, the operating platform, the
motor control cabinet, the intermediate frequency power supply, the
compensation capacitor, the water cable, the intermediate frequency
coil adjusting frame, the reactor and other components.Medium
frequency tube expanding machine has an advantage is the
intelligent constant temperature system, can effectively avoid due
to human factors caused by the temperature is too high to pull down
the quality of the steel tube and die scrap, or the temperature is
too low to cause the rod and die fracture phenomenon, put an end to
the unsafe factors.
