[0002] Nondestructive testing refers to the premise that the internal structure of the detected object is not damaged, the changes of heat, sound, light, electricity, magnetism and other reactions caused by the existence of internal structure abnormalities or defects are utilized, and the structure, state and defects of the inside and surface of the test piece are checked and tested by equipment.

[0003] The existing nondestructive testing equipment is mostly used for the detection of hard workpieces. When the hard workpieces are detected, they will be subjected to different forces of action of different detection mechanisms. The hard workpieces are detected by pushing or extruding. However, these forces of action will change the state of some soft workpieces such as steel wires, causing the soft workpieces to deform or even be damaged. The soft workpieces cannot be well nondestructively tested. How to optimize the detection equipment to realize the nondestructive testing of soft workpieces is a technical problem to be solved at present. SUMMARY

It utilizes the difference between the magnetic permeability of the surface and near-surface defects (such as cracks, slag inclusion, grain lines, etc.) of steel products and the magnetic permeability of steel. After magnetization, the magnetic field at the discontinuous place of these materials will be distorted, forming a part of the magnetic flux leakage. The workpiece surface produces a leakage magnetic field, so as to be detected.

[0015] By adopting the technical scheme, the locking bolt is tightened to abut against the sliding rail, thereby locking and fixing the sliding seat on the sliding rail through friction, so as to reduce the possibility of movement of the sliding seat during use, and improve the stability of the soft workpiece positioning.

[0016] Preferably, the feeding roller and the collecting roller are rotatably arranged on the machine body in a detachable manner, the machine body is provided with a collecting motor, and the rotating shaft of the collecting motor is detachably connected with the collecting roller.

[0017] By adopting the technical scheme, the collecting motor drives the collecting roller to rotate, thereby driving the soft workpiece to move and feed, and the collecting roller and the feeding roller are detachably installed, so as to facilitate the feeding before the detection of the soft workpiece and the collection after the detection, and improve the convenience of use.

[0018] Preferably, the machine body is provided with a demagnetization mechanism and a marking mechanism, the demagnetization mechanism is used for demagnetizing the soft workpiece, and the marking mechanism is used for marking the soft workpiece according to the detection result.
