Description

Technical Field

[0001] The utility model relates to the technical field of stainless steel bar flaw detection, in particular to an off-line surface eddy current flaw detection machine for stainless steel bars. Background Art

[0002] Offline eddy current flaw detectors for stainless steel bars are essential equipment for material quality control in modern industry. These high-precision devices utilize the principle of electromagnetic induction to identify surface and near-surface defects by detecting eddy current variations in the material. This equipment is suitable not only for stainless steel but also for a wide range of metals, including aluminum, copper, titanium, and other alloys. Eddy current testing is based on the principle of electromagnetic induction. When alternating current passes through one or more coils of wire, it generates an alternating magnetic field. When a probe is placed near a conductive material, such as a metal bar, this alternating magnetic field induces eddy currents in the material. These eddy currents themselves generate a magnetic field, which interacts with the original magnetic field, altering the electrical impedance of the coil. Therefore, any surface or near-surface discontinuity or characteristic change, such as a crack or thickness variation, alters the distribution of the eddy currents, which in turn affects the magnetic field and ultimately changes the electrical impedance of the measuring coil. Using this principle, eddy current flaw detection equipment can detect tiny defects in materials.

[0003] Based on the above, the inventors have found the following problem: the existing offline eddy current flaw detection machine for stainless steel bars does not have an automatic feeding function when in use, resulting in low detection efficiency and affecting user use.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and an offline surface eddy current flaw detection machine for stainless steel bars is provided, in order to achieve the purpose of having more practical value. Utility Model Content
