[0022] Reference Figure 1 and Figure 2 This utility model provides an embodiment of a rapid sample preparation device for performance testing of rare earth permanent magnet materials, comprising a fixed plate 1, a base 11 fixedly connected to the lower surface of the fixed plate 1, a motor 2 fixedly connected inside the fixed plate 1, a rotating column 3 fixedly provided at the output end of the motor 2, a rotating block 4 fixedly connected to the outer wall of the rotating column 3, a first connecting shaft 5 fixedly connected to the outer wall of the rotating block 4, a connecting piece 6 rotatably connected to the outer wall of the first connecting shaft 5, a second connecting shaft 7 rotatably connected inside the connecting piece 6, a sliding plate 8 fixedly connected to the outer wall of the second connecting shaft 7, a slide rail 9 slidably connected to the outer wall of the sliding plate 8, the outer wall of the slide rail 9 fixedly connected to the outer wall of the fixed plate 1, and a support assembly provided on the outer wall of the sliding plate 8 for auxiliary support.
[0023] Specifically, the fixing plate 1 provides fixed support for the motor 2, which in turn drives the rotating column 3 to rotate the rotating block 4. The rotation of the rotating block 4 simultaneously drives the first connecting shaft 5 to rotate, which in turn drives the connecting piece 6 to move. The connecting piece 6 drives the second connecting shaft 7, which in turn drives the sliding plate 8 to slide on the outer wall of the slide rail 9. The slide rail 9 limits the sliding plate 8. The fixing plate 1 provides fixed support for the slide rail 9. The sliding plate 8 drives the connecting block 10, which in turn drives the fixing box 12 to move. This allows the shaping block 20 to press and shape the rare earth permanent magnet material. The base 11 holds the rare earth permanent magnet material.
[0024] Reference Figure 1 The support component includes a connecting block 10, the outer wall of which is fixedly connected to the outer wall of the sliding plate 8, and a fixing box 12 is fixedly connected to the outer wall of the connecting block 10.
[0025] Specifically, the sliding plate 8 provides fixed support for the connecting block 10, the connecting block 10 provides fixed support for the fixed box 12, and the connecting block 10 connects the sliding plate 8 and the fixed box 12.
[0026] Reference Figure 1 and Figure 3 A fixing plate 13 is fixedly connected to the inner wall of the fixing box 12. A fixing shaft 14 is fixedly connected inside the fixing plate 13. A limit block 15 is rotatably connected to the outer wall of the fixing shaft 14. A pressure block 16 is fixedly connected to the outer wall of the limit block 15. A spring 17 is fixedly connected to the upper surface of the pressure block 16. The outer wall of the spring 17 is fixedly connected to the inner wall of the fixing box 12.

A shaping block 20 is fixedly connected to the lower surface of the fixing block 19.
[0027] Specifically, the molding block 20 drives the fixing block 19, which in turn drives the extrusion column 18 to compress the limiting block 15. The limiting block 15 drives the pressure block 16 to compress the spring 17. The fixing box 12 provides fixed support for the fixing plate 13 and the spring 17. The limiting block 15 rotates on the outer wall of the fixing shaft 14 to allow for quick installation and removal of the molding block 20. The fixing shaft 14 inside the fixing plate 13 limits the position of the limiting block 15.
[0028] Working principle: When the device is needed, the rare earth permanent magnet material is placed on the upper surface of the base 11.

The rotation of the rotating block 4 drives the first connecting shaft 5 to rotate, which in turn drives the connecting piece 6. The connecting piece 6 drives the second connecting shaft 7, which in turn drives the sliding plate 8 to slide on the outer wall of the slide rail 9. The sliding plate 8 drives the connecting block 10, which in turn drives the fixing box 12. This allows the shaping block 20 to press and shape the rare earth permanent magnet material. The shaping block 20 drives the fixing block 19, which in turn drives the extrusion column 18 to extrude the limiting block 15. The limiting block 15 drives the pressure block 16 to extrude the spring 17. The positioning block 15 rotates on the outer wall of the fixed shaft 14, allowing for quick installation and removal of the molding block 20. This device not only ensures uniform pressure and density distribution during sample preparation but also rapidly and effectively presses and shapes rare earth permanent magnet materials, significantly shortening sample preparation time. The efficient pressing process enables the preparation of a large number of samples in a short time, improving overall work efficiency. Furthermore, since pressing and shaping rare earth permanent magnet materials requires molds of different shapes and sizes to prepare samples of different specifications, this device makes mold and component replacement easier, allowing for rapid adjustment of equipment configuration according to testing needs. This helps meet diverse testing requirements and improves the flexibility and adaptability of the equipment.
