The bending formula of medium frequency pipe bender

Medium frequency pipe bending machine is an advanced equipment for twisting metal pipes, often used in the manufacture of automotive exhaust pipes, air conditioning pipes and other applications. In the process of pipe bending, it is necessary to determine the appropriate bending radius, Angle and bending force to ensure the quality and accuracy of the pipe bending.

The bending formula of medium frequency pipe bender is closely related to mechanical parameters, material properties and technological requirements. Here are some common bending formulas:

1. Bending radius formula:

The bending radius (R) is related to the outer diameter (D) and bending Angle (θ) of the pipe. In general, the bending radius can be calculated by the following formula:

R = D/(2 * sin(θ/2))

2. Bending force formula:

The bending force (F) is related to the material properties (such as elastic modulus), outer diameter (D), wall thickness (t), and bending Angle (θ) of the pipe. The bending force can be calculated by the following formula:

F = (E * I * κ)/(R * t)

Where, E is the elastic modulus of the tube, I is the moment of inertia of the tube section, and κ is the bending coefficient.

3. Bending Angle formula:

The bending Angle (θ) is related to the material properties (such as yield strength), outer diameter (D), wall thickness (t), and bending force (F) of the pipe. The bending Angle can be calculated by the following formula:

θ = (F * R * t)/(E * I)

4. Bending force formula:

Bending strength refers to the degree of stress on the pipe during bending. The bending force is related to the material properties, bending radius, bending Angle and the outside diameter of the pipe.

The above formulas are only some common pipe bending formulas, and other factors need to be considered in practical application, such as the bending deformation of the pipe and the mechanical parameters of the pipe bending machine. In addition, there may be differences between different types of intermediate frequency pipe bending machines, so the specific formula may be different.

In short, the bending formula of medium frequency pipe bender is a complicated problem, which needs to consider many factors. In practical applications, it is also necessary to adjust and optimize according to the actual situation to ensure the quality and accuracy of the bending pipe.
