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.
