How to measure the rebound number of the pipe when sharing the CNC pipe bender: When the external force is removed, the part of the pipe that was bent returns to its original condition, and the bending angle of the measured pipe is smaller than the required bending angle. This is what it is usually said. The rebound of the tube. When bending and forming, the metal material is deformed by force and is bent into an angle. There are many factors that affect the receipt, and this is a more complicated issue. Bending different materials, different diameters, different bending radii, and using different tooling and adjusting the process parameters of the pipe bender will affect the rebound of the pipe. But after the machine tool is adjusted, the process parameters (bending radius, bending speed, clamping force, etc.) have been determined, and in the case of bending a certain batch of material pipes, the relationship between the bending angle and the springback is measured, thus simplifying Some factors that affect the springback can be regarded as a linear relationship between the angle of the bending arm of the pipe bender and the bending angle of the pipe. This is a simple and practical way to determine the springback.
