Intermediate frequency tube expanding machine

Intermediate frequency expanding machine is a kind of expansion pipe unit period of intermediate frequency heating method and device, its period of intermediate frequency heating method is: when the steel tube on the expansion unit is fed into the spiral induction coil within and between mandrel, consists of three independent of intermediate frequency power supply for three spiral induction coil to provide the power and temperature control of steel pipe in the spiral induction coil current under the action of heating, the heating temperature is divided into preheating section, thermal expansion and sizing, steel pipe by the driving of the power unit forward direction, core mold close to the steel tube wall, and decide the final steel pipe diameter size, to suit the requirements of processing.The multi-stage intermediate frequency heating device of the tube expanding unit consists of three spiral inductors independently installed on the tube expanding unit with different diameters. The three spiral inductors are divided into the preheating spiral inductor, the thermal expanding spiral inductor and the sizing spiral inductor. Each spiral inductor is equipped with an independent intermediate frequency power supply.

Equipment advantage: intelligent constant temperature system.In addition to the intermediate frequency tube expanding machine, aocheng machinery equipment co., LTD also produces three-way machine, elbow push machine, intermediate frequency tube bending machine, four-column gantry press, etc., exported to the world, including the United States, Malaysia, India and other countries.
