Description

Technical Field

[0001] The utility model relates to the technical field of preventing devices, in particular to a device for preventing bending of a flaw detection wire. Background Art

[0002] Magnetic flux leakage testing refers to the use of magnetic traces to display the defects of ferromagnetic materials and their products. Magnetic particle testing can detect tiny defects that are exposed on the surface and cannot be directly observed with the naked eye or with the help of a magnifying glass. It can also detect near-surface defects that are not exposed on the surface but buried a few millimeters below the surface. The principle of flaw detection is that when the ferromagnetic steel pipe is fully magnetized, the magnetic lines of force in the pipe wall are blocked by defects on its surface or near the surface, and the magnetic lines of force at the defects are distorted. Part of the magnetic lines of force leak out of the inner and outer surfaces of the steel pipe to form a leakage magnetic field. The electromagnetic detection method that uses detection elements to detect leakage magnetic fields to find defects is called magnetic flux leakage testing. When the detection element located on the surface of the steel pipe and moving relative to the steel pipe picks up the leakage magnetic field and converts it into a defect electrical signal, a signal reflecting the defect can be obtained through the probe, thereby determining and processing the defect. The flaw detection sensitivity is the highest on the outer surface of the steel pipe, and decreases with the increase of wall thickness from the outer surface to the inner surface. When the defect is perpendicular to the direction of the magnetic lines of force, the leakage magnetic field intensity at the defect is the largest, and the flaw detection sensitivity is also the highest. As the defect direction deviates, the leakage magnetic field strength gradually decreases until the two directions are consistent, and the leakage magnetic field strength is close to zero. Therefore, when using longitudinal and transverse flaw detection equipment, it is not very sensitive to oblique defects and is prone to forming blind corners.

[0003] However, during the use of existing flaw detection equipment, the leakage magnetic flaw detection wire probe needs to be close to the surface of the bar, and the probe rotates 360° around the steel. In order to avoid damaging the probe, which may lead to production accidents and loss of flaw detection equipment, the flaw detection wire has a high bending requirement. Although it undergoes a straightening process before flaw detection, it is still possible that the steel that exceeds the standard may be bent and enter the flaw detection equipment, resulting in production accidents. Therefore, technical personnel in this field provide a flaw detection wire bending prevention device to solve the problems raised in the above background technology. Utility Model Content
