Medium frequency pipe expanding machine is an important equipment widely used in the field of pipeline processing, mainly used to expand the diameter of the pipeline, so that it can better adapt to various engineering needs. Before we understand the frequency of an intermediate frequency tube expanding machine, we need to understand its working principle, application field, and the effect of frequency on its performance.
First, the working principle of medium frequency tube expanding machine
The core principle of intermediate frequency pipe expanding machine is to use the electromagnetic field generated by the intermediate frequency current through the inductor to act on the metal pipe. Through electromagnetic induction heating, the metal material is plastic deformed at high temperature, so as to achieve the expansion of the pipe. This process usually involves the following steps:
1. ** Heating ** : intermediate frequency power supply converts mains power into intermediate frequency current through the transformer, and the current passes through the induction coil to produce an alternating magnetic field. The heated metal pipe generates eddy currents inside, which causes the material inside the pipe to heat up rapidly.
2. ** Expanding ** : After the pipeline reaches a certain temperature, the mechanical device is used to apply expanding force to the heated pipeline. At this time, the metal material has good plasticity and can be deformed under the action of external forces.
3. ** Cooling ** : After the expansion is completed, the pipe needs to be cooled to solidify its new shape. The speed and way of cooling will directly affect the effect of pipe expansion and the internal stress state of the pipe.
Two, the frequency of medium frequency tube expanding machine
The frequency of the medium frequency pipe expanding machine is usually between 1kHz and 10kHz. The choice of frequency has an important impact on the heating efficiency, forming quality and the service life of the equipment.
### 1. Effect of frequency on heating efficiency
The higher the frequency, the higher the efficiency of induction heating, but at the same time, it also has an impact on the heating of the material. The high frequency current will cause eddy currents to concentrate on the surface of the material, resulting in excessive surface temperature and insufficient internal temperature. Therefore, choosing the right frequency is crucial.
#### 2. Influence of frequency on forming quality
Forming quality is one of the important indexes to evaluate the performance of medium frequency tube expanding machine. The change of frequency will directly affect the heating uniformity of the pipeline. If the frequency is too low, it may lead to uneven heating of the material, which will affect the shape and dimensional accuracy of the expanded tube.
#### 3. The influence of frequency on the service life of equipment
The choice of frequency will also affect the service life of the equipment. Too high a frequency may cause the device to heat up too quickly, thus accelerating the wear of the device. If the frequency is too low, it may cause the equipment to work inefficiently, increase the working time and energy consumption. Therefore, when choosing the frequency, it is necessary to take into account the processing effect, and take into account the economy and durability of the equipment.
3. Application field of medium frequency tube expanding machine
