[0002] A magnetic tile is a type of permanent magnet primarily used in permanent magnet motors. Below the Curie temperature, numerous small regions with their own spontaneous magnetic moments, arranged in pairs, exist within ferromagnetic or ferrimagnetic materials. These regions are arranged in disordered directions, and without a magnetic field, their overall magnetic moment is zero. These small regions are called magnetic tiles.

[0003] The existing Chinese utility model patent with reference publication number CN216706102U discloses a magnetic tile cutting device that is easy to fix, comprising a base, a cutting mechanism, and a positioning mechanism. The base is provided with a support column, and a top plate is provided on top of the support column. The cutting mechanism includes a telescopic cylinder, a cutting plate, a cutting disc, and a drive motor. The cutting plate is located below the telescopic head of the telescopic cylinder. Two mounting plates are provided at the bottom of the cutting plate. The positioning mechanism includes a cutting table, a clamping plate, a clamping block, and a limit assembly. The cutting table is located below the cutting disc. Two clamping plates and two clamping blocks are provided. The two clamping plates are located on either side of the cutting table. A clamping groove that matches the clamping block is provided on the side of the clamping plate facing the cutting table. The clamping groove is located above the cutting table. A return spring is provided between the clamping block and the clamping groove. The utility model provides a magnetic tile cutting device that is easy to fix.

At the same time, the existing cutting device cannot be adjusted according to the curvature of the magnetic tile during use, and the scope of application is small. Utility Model Content
