Technical points of medium frequency pipe bending machine

Medium frequency pipe bending machine is a kind of equipment commonly used for metal pipe bending processing, it adopts the principle of medium frequency induction heating, under the premise of not changing the physical properties of the pipe, by controlling the heating and cooling process, so that the pipe can be bent into the desired shape. The following are the technical points of the medium frequency pipe bender:

1. Structural design: The main components of the medium frequency pipe bending machine include frame, pipe bending shaft, hydraulic system, medium frequency induction heating system, control system, etc. The frame needs to have sufficient stiffness and stability to withstand the forces and vibrations of the bending process. The bending shaft needs to have sufficient torsional stiffness and precision to ensure the accuracy of the bending.

2. Medium frequency induction heating system: medium frequency induction heating is the key technology of medium frequency pipe bending machine. The principle is to convert electrical energy into thermal energy through electromagnetic induction, so that the local heating of the pipe to the plasticity temperature, so as to achieve bending. The medium frequency induction heating system includes induction coil, induction power supply and cooling system. Induction coils need to be designed according to the size and shape of the pipe to ensure heating uniformity and efficiency.

3. Pipe bending process control: The control system of the medium frequency pipe bending machine needs to achieve accurate control of the bending process. It includes the control of heating power, heating time, cooling time, bending speed and other parameters. By setting these parameters reasonably, the Angle, curvature radius and quality of the bending pipe can be controlled.

4. Pipe bending mold design: medium frequency pipe bending machine needs to design the corresponding pipe bending mold according to different pipe sizes and shapes to ensure the accuracy and quality of pipe bending. Pipe bending dies are usually made of alloy steel and need to have sufficient hardness and wear resistance. The design of the bending mold should take into account the force and thermal deformation during the bending process to ensure the life of the mold and processing accuracy.

5. Stability protection measures: The medium frequency pipe bending machine needs to take into account the safety of the operator during the operation. Because the heating process will produce high temperature and radiation, it is necessary to set up the corresponding stable protection facilities, such as safety doors, protective covers, temperature monitoring and alarm systems.

6. Mechanical transmission system: The mechanical transmission system of the medium frequency pipe bending machine needs to ensure the movement accuracy and smoothness of the bending pipe. Common transmission methods include hydraulic drive, mechanical gear drive and servo motor drive. The design of the transmission system should take into account the stress of the bending pipe and the working environment to ensure the reliability and stability of the transmission.

In summary, the medium frequency pipe bender has important technical points in structural design, medium frequency induction heating system, bending process control, bending mold design, safety protection measures and mechanical transmission system. As long as these aspects are well designed and controlled, in order to ensure the efficient, accurate and stable operation of the medium frequency pipe bender.
