Pipe expanding machine manufacturers

The simple components of the pipe expander include: base, main cylinder, movable support plate, front support plate, automatic feeding structure, feeding roller table, mold bracket, intermediate frequency coil and intermediate frequency heating coil, intermediate frequency power supply, electrical control system and so on.

The pipe expanding machine and the pipe expanding machine can expand the diameter of the steel pipe from 60mm-1420mm, the wall thickness of 3mm-120mm, the length of the steel pipe above 3-24mm. The pipe expanding machine of our company can produce these expanded steel pipe models.

The advantages of pipe expanding machine and diameter expanding machine are: energy saving, simple operation, high production efficiency, reduce the cost of workers, and one person can operate more than one pipe expanding machine.

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

The advantages and disadvantages:

Advantages: save manpower, protect the internal structure of the steel pipe, a wide range of materials, suitable for large steel pipe, easy to operate the machine;

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