Description

Technical Field

[0001] The utility model belongs to the technical field of demagnetization machines, and in particular relates to a demagnetization machine for non-destructive testing. Background Art

[0002] Demagnetizers are generally used for demagnetizing permanent magnetic materials and low coercive force materials (hardware, mold steel, etc.), and can be divided into pulse demagnetization and AC demagnetization. Demagnetization is to place the workpiece in an alternating amplitude that gradually decreases, and the trajectory of the hysteresis loop becomes smaller and smaller. When the magnetic field intensity drops to zero, the residual magnetism Br in the workpiece is close to zero. During demagnetization, the changes in the direction and magnitude of the current and magnetic field must be "commutation attenuation at the same time".

[0003] However, the existing demagnetization machine does not have the function of adjusting the height of the demagnetization ring. The demagnetization ring is located above the conveyor belt, and the distance between the demagnetization ring and the conveyor belt is often fixed. Therefore, when the height of the workpiece is greater than the distance between the demagnetization ring and the conveyor belt, the workpiece cannot be demagnetized by the demagnetization ring, resulting in the inconvenience of using the demagnetization machine. Therefore, a demagnetization machine for non-destructive testing is urgently needed to solve the above problem. Utility Model Content
