Intermediate frequency heating alloy steel tube expanding machine
The structure and principle of tube expanding machine
The tube expanding machine is a parallel equal-speed hydraulic
pusher with double cylinders. Pipe-expanding machine feeding by the
feeding winding machine, the stock moving wire rope, push the pipe
through the wire rope wheel, reciprocating operation, to expand the
primary pipe into the equipment.

The intermediate frequency power supply of the tube expanding
machine is installed at the front end of the equipment, and the
intermediate frequency induction coil is placed on the coil
adjusting frame, and the coil can be adjusted up and down, forward
and backward. After the core reamer dies and the core reamer, the
pump and the intermediate frequency power supply are opened and the
intermediate frequency power is adjusted, the core reamer dies and
the pipe can be heated and the pipe can be gradually pushed
forward. The pipe will rise to a certain temperature with the
heating temperature, resulting in plastic deformation. The pipe can
be expanded by pushing forward along the outside diameter of the
mandrel.
The controllable silicon, intermediate frequency coil, reactor and
other components of tube expander need circulating water cooling.
Some of the electrical control of the tube expanding machine is
installed in the total control cabinet, the tube expanding machine
is installed at both ends of the trip switch, push the plate in
place, active parking.
