Principle and structure of medium frequency pipe bending machine

Medium frequency pipe bending machine is a kind of machine which uses medium frequency induction heating technology to process pipe bending. The machine has the advantages of compact structure, simple operation, high bending precision and high production efficiency.

The working principle of the medium frequency pipe bending machine is to use the principle of electromagnetic induction heating to put the metal pipe into the working coil, and the induction current generated by electromagnetic induction forms an induction electric field inside the pipe, so that the pipe generates heat. When the pipe reaches the desired temperature, the pipe is bent by mechanical force, and after reaching the desired shape, the pipe is cooled to room temperature by a cooling system.

The medium frequency pipe bender is mainly composed of induction heating system, pipe bending structure, control system and cooling system.

Induction heating system is the core part of medium frequency pipe bending machine, which is mainly composed of induction coil, medium frequency power supply and water cooling equipment. The induction coil is a metal ring installed in the working area of the machine to generate an electromagnetic field. Medium frequency power supply is a device that controls the electromagnetic wave generated by the coil, and it can adjust the frequency and current size of the electromagnetic wave generated by the induction coil to control the heating temperature and time of the pipe. Water cooling equipment is used to cool the induction coil cooling system, it can ensure that the induction coil for a long time continuous operation without overheating.

The pipe bending structure is another important part of the medium frequency pipe bending machine, which is mainly composed of the pipe bending frame, the pipe bending die, the pipe bending wheel and other parts. The bending frame is mainly used to support the structure of the bending pipe, the bending mold is a tool for shaping the pipe, and the bending wheel can keep the pipe in the bending process.

The control system is the automatic control part of the medium frequency pipe bender, which can realize the automatic control of the process of pipe heating, bending and cooling. The control system includes PLC controller, touch screen, electronic control element and so on. PLC controller is the core control equipment of medium frequency pipe bending machine, which can automatically control the whole process according to the preset program. The touch screen is an interactive interface between the operator and the control system, which can easily adjust and modify the machining parameters. The electronic control components include solenoid valves, relays, contactors and other electrical components, which are used to control the action of the bending structure.

The cooling system is the last component of the medium frequency pipe bending machine, which is mainly composed of cooling water tank, cooling pump, cooling pipeline, etc. The cooling system can quickly cool the pipe to room temperature to ensure that the shape of the pipe is not deformed after bending.

In short, the medium frequency pipe bending machine is an efficient and automatic pipe processing equipment. It uses electromagnetic induction heating technology, which can accurately process metal pipes, and is widely used in the manufacturing of automobiles, aviation, machinery, construction and other fields.
