[0002] NdFeB magnets can be divided into bonded NdFeB and sintered NdFeB. Bonding is actually injection molding, while sintering is vacuum molding through high-temperature heating. NdFeB magnets are permanent magnets with the strongest magnetic force at room temperature so far. At absolute zero, their magnetic force is second only to holmium magnets, but at room temperature, their magnetic force is much stronger than all currently known permanent magnets. This magnet has an extremely high magnetic energy product and is the permanent magnet with the second highest magnetic force after holmium magnets at absolute zero.

[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0025] Please refer to Figures 1 - 5 , the present invention provides the following technical solutions: A double-headed punching device for processing neodymium iron boron magnets, including a substrate 1, a movable drilling mechanism 2, a workbench 3, a base 4 and a hopper 5. The movable drilling mechanism 2 is installed on the upper surface of the substrate 1, the workbench 3 is installed on the upper surface of the substrate 1, the base 4 is installed on the top of the workbench 3, the hopper 5 is installed on the top of the base 4, a cylinder pushing mechanism 6 is installed on one side of the base 4, and the telescopic end of the cylinder pushing mechanism 6 is connected to a pushing slide plate 7;

[0026] On the other side of the base 4, there is an end plate 8. The mounting bracket 9 is installed on the upper surface of the end plate 8. The telescopic cylinder 10 is connected through the top of the mounting bracket 9. The telescopic end of the telescopic cylinder 10 is connected to a baffle 11. The baffle 11 is inserted into the inside of the end plate 8. The first guiding slide rail 12 is connected to the side surface of the baffle 11, and the first guiding chute 13 is opened on the side surface of the end plate 8 close to the first guiding slide rail 12.

[0027] Preferably: A hydraulic telescopic structure is formed between the baffle 11 and the telescopic cylinder 10. The first guiding slide rail 12 and the first guiding chute 13 are symmetrically arranged on both sides of the central axis of the baffle 11. The first guiding slide rail 12 is slidably connected to the end plate 8 through the first guiding chute 13.

[0028] During specific use, when the telescopic cylinder 10 operates, it can extend. When the telescopic cylinder 10 extends, it can drive the baffle 11 to generate a force. When the baffle 11 receives the force, it can drive the first guiding slide rail 12 to slide downward inside the first guiding chute 13. When the baffle 11 moves to the upper surface, at this time, the cylinder pushing mechanism 6 squeezes the pushing slide plate 7 to move horizontally and squeezes the neodymium iron boron magnet raw material. The neodymium iron boron magnet raw material can move in the direction close to the baffle 11 under the extrusion. When the neodymium iron boron magnet raw material moves horizontally to one side surface of the baffle 11, the position of the neodymium iron boron magnet raw material can be fixed at this time, and the two sides of the neodymium iron boron magnet raw material can be drilled simultaneously through the movable drilling mechanism 2. After the drilling is completed, the movable drilling mechanism 2 can be reset. At this time, the telescopic cylinder 10 drives the baffle 11 to move upward. When the bottom end of the baffle 11 moves to the upper surface of the neodymium iron boron magnet raw material, at this time, the cylinder pushing mechanism 6 pushes the pushing slide plate 7 to move horizontally and pushes the neodymium iron boron magnet raw material to the end of the base 4 and fall on the workbench 3. Then, the cylinder pushing mechanism 6 pulls the pushing slide plate 7 to reset;

[0029] Preferably, a second guiding slide rail 14 is connected to the inner wall of the end plate 8. A second guiding chute 15 is provided on the side surface of the base 4 close to the second guiding slide rail 14. A threaded hole 16 is provided on the surface of the end plate 8. A threaded rod 17 penetrates through the inside of the threaded hole 16. A first bearing 18 is installed between the threaded rod 17 and the base 4. A driven bevel gear 19 is connected to the end of the threaded rod 17. A second bearing 20 is installed inside the base 4. A rotating rod 21 penetrates through and is connected inside the second bearing 20. A driving bevel gear 22 is connected to the surface of the rotating rod 21.

[0030] Preferably, the second guiding slide rail 14 and the second guiding chute 15 are symmetrically arranged on both sides of the central axis of the base 4. The second guiding slide rail 14 and the base 4 form a sliding connection through the second guiding chute 15. The threaded rod 17 and the first bearing 18 form a rotating structure. The threaded rod 17 and the threaded hole 16 are in a threaded connection. The rotating rod 21 and the second bearing 20 form a rotating structure. The driving bevel gear 22 and the driven bevel gear 19 form a meshing structure.

[0031] During specific use, rotating the rotating rod 21 can drive the driving bevel gear 22 to rotate. When the driving bevel gear 22 rotates, it can generate a force on the driven bevel gear 19. When the driven bevel gear 19 receives the force, it can drive the threaded rod 17 to rotate inside the first bearing 18. When the threaded rod 17 rotates, it can drive the end plate 8 to move horizontally through the threaded hole 16. When the end plate 8 moves horizontally, it can drive the baffle 11 to move horizontally through the telescopic cylinder 10, so that the position of the baffle 11 can be adjusted. In this way, the neodymium iron boron magnet raw material can be fixed at different positions, and thus drilling can be performed on different positions of the neodymium iron boron magnet raw material.

[0032] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or perform equivalent replacements on some of the technical features. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
