Medium frequency pipe bender is traditional equipment

Medium frequency pipe bender is a kind of traditional equipment used for bending metal pipes. It uses the heating effect of a mid-frequency current to soften metal pipes and bend them into the desired shape by mechanical force. The following will introduce the principle, structure, working process and application field of the medium frequency pipe bending machine in detail.

I. Principle

The working principle of the medium frequency pipe bending machine is based on the principle of electromagnetic induction heating. By passing a medium frequency current through the metal pipe, a strong eddy current can be generated on the surface of the pipe. These eddies create frictional heat on the surface of the pipe, heating up the metal pipe rapidly. When a metal reaches a certain temperature, it becomes soft and can be bent by mechanical force.

Ii. Structure

Medium frequency pipe bending machine is mainly composed of power supply system, induction coil, mechanical device and control system.

1. Power supply system: medium frequency pipe bender usually uses medium frequency generator as power supply to convert electrical energy into medium frequency current. This intermediate frequency current has a higher frequency and a smaller voltage to meet the heating needs of metal pipes.

2. Induction coil: Induction coil is the core part of the medium frequency pipe bending machine, which is used to generate electromagnetic induction field. It usually consists of a set of coils wound into a circular ring and fixed to the work table of the machine. When an intermediate frequency current passes through the induction coil, it creates a strong magnetic field around the coil, which creates eddy currents.

3. Mechanical devices: Mechanical devices are used to apply force and control the bending process. It usually consists of a hydraulic system, a bending head and a clamp. The hydraulic system provides the force needed to bend, the bending head is responsible for applying force on the metal pipe, and the clamp is used to hold the metal pipe in place to maintain its stability.

4. Control system: The control system is used to monitor and regulate the working process of the medium frequency pipe bender. It can control the temperature, adjust the bending Angle and control the motion of the mechanical device.

Third, the working process

The working process of medium frequency pipe bending machine generally includes the following steps:

1. Place the metal pipe on the fixture of the mechanical device and fix it.

2. Turn on the power system to make the medium frequency current pass through the induction coil and generate a strong magnetic field.

3. The medium frequency current generates eddy currents on the surface of the metal pipe, causing the metal pipe to heat up.

4. When the metal pipe reaches a soft temperature, start the mechanical device and apply force on the pipe.

5. Through the control system, the movement of the mechanical device is adjusted to bend the metal pipe into the desired shape.

6. After bending, turn off the power system and stop the heating of the intermediate frequency current.

4. Application field

Medium frequency pipe bending machine is widely used in the manufacturing industry, especially in the field of pipe processing, pipe installation and metal structure manufacturing. It can be used to bend various metal pipes, such as steel pipes, copper pipes, aluminum pipes, etc., so as to meet the needs of different industries. Common applications include piping systems, HVAC systems, petrochemical equipment, ship construction, automobile manufacturing, etc.

To sum up, an intermediate frequency pipe bender is a conventional device that uses the heating effect of an intermediate frequency current to soften a metal pipe and bend it into the desired shape by mechanical force. It has the characteristics of simple structure, stable work and easy operation, and plays an important role in the fields of pipeline processing and metal structure manufacturing.
