Intermediate frequency heating tube expander

Principle of tube expansion: the use of electromagnetic induction, the steel tube heating, resulting in deformation;

Process of tube expansion: the inner wall of the steel tube to be expanded is brushed with lubricant the steel tube (with fixed mandrel) is fixed on the corresponding platform heating mandrel, push the steel tube to the mandrel the steel tube meets high temperature mandrel, easy to deform, with the size of the radius of the mandrel finally fixed shape;

The main components of the machine: frame motor cone punch chuck hydraulic system;

Scope of application: diameter range of steel tube: 21mm -- 1620mm;The thickness range of steel tube wall: 3mm -- 100mm;

The advantages and disadvantages:

Advantages: save manpower, protect the internal structure of steel tube, steel tube has a wide range of materials, suitable for large steel tube, convenient machine operation;

Disadvantages: not suitable for small steel tube, forming time is longer, smear lubrication is not convenient;
