Intermediate frequency tube expanding machine

Tube expander is a special equipment for hot diameter expansion of steel tubes. It is designed for the production of large diameter seamless steel tubes and the specification is not enough to meet the domestic and foreign market demand.It is the main production technology of large diameter steel tube at present.The main power source of the equipment is the parallel equal-speed push machine with two or four oil cylinders. The valve platform of the pump station adopts the integrated form. The power of the medium-frequency heating power supply, the thrust and stroke of the oil cylinder are set according to the outer diameter and length of the steel tube to be expanded.

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.

In addition, compared with manual heating of steel pipe, the intermediate frequency tube expander simplifies the process and reduces labor cost and time.Increased production efficiency
