The expanding principle of medium frequency tube expander: the steel tube is heated by electromagnetic induction, which leads to deformation;

Pipe expansion process: (1) the inner wall of the steel pipe to be expanded with a lubricant (2) the steel pipe (with a fixed mandrel) is fixed on the corresponding platform (3) the heating mandrel, the steel pipe is pushed to the mandrel (4) the steel pipe meets the high temperature mandrel, easy to deform, and the size of the mandrel radius is finally fixed and formed;

The main components of the machine: ① frame ② motor cone punch ③ chuck ④ hydraulic system, etc.;

Scope of application: ① steel pipe diameter range: 21mm-1620mm;(2) steel tube wall thickness range: 3mm -- 100mm;

Advantages: save manpower, protect the internal structure of the steel pipe, the steel pipe material range is wide, suitable for large steel pipe, convenient operation of the machine;Energy saving, simple operation, high production efficiency, reduce the cost of workers, can do a person to operate more than one set of pipe expansion machine.

Disadvantages: not suitable for small steel pipe, forming time is longer, the application of lubrication is not convenient;

In the production process of the medium frequency pipe expander, the pipe material moves in the way of translation when the pipe expander expands, which is stable and accurate and will not hurt the pipe material.This machine adopts the heating mode of hot air and double heating, each heating furnace is equipped with a multi-step heating furnace core.The molding method adopts the qualitative way of the expansion pipe head and the external pressure, and the size of the nozzle is accurate. The machine is equipped with a transfer switch of expanding solvent type acceptance port (straight port) and expanding elastic sealing ring type socket socket (R port) on the control panel.And the R port is divided into the way that the block rises first and the block rises later.The selection of tube expanding mode is very convenient and the process is adaptable. The main electrical control components are all components. The system performance is stable and reliable.
