[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Embodiment 1:

[0025] like Figures 1 to 4 As shown, this embodiment proposes a sintering furnace for the production of NdFeB strong magnets, the device mainly includes a box body 1, a screw rod 6 and a moving platform 10, wherein the box body 1 is a square shell, a rotating structure 2 is arranged at the middle of the lower part, a box cavity 3 is arranged inside the box body 1, and the rotating structure 2 is located below the box cavity 3, and at the same time, a base 4 is arranged at the bottom end of the box cavity 3, and the two can be used in conjunction with each other, and a furnace door 5 used in conjunction with the box cavity 3 is arranged at the front end of the box body 1; a control part 17 is arranged at the rear part of one side of the box body 1, and heat dissipation parts 18 are arranged at the lower parts of both sides of the box body 1.

[0026] Next, the above-mentioned screw rod 6 is arranged on both sides of the top of the base 4, and the front and rear ends of the screw rod 6 are rotatably connected to the rod seat 7, the rod seat 7 is fixedly connected to the base 4, and the screw rods 6 on both sides are threadedly connected with threaded blocks 8, and the separated sides of the screw rods 6 on both sides are provided with support feet 9, and the support feet 9 are fixedly connected to the top of the base 4; behind the screw rod 6 is a motor 26 located outside the box body 1, the output shaft of the motor 26 passes through the box body 1 and is fixedly connected to the screw rod 6, the bottom end of the motor 26 is fixedly connected to a motor seat 27, and the motor seat 27 is fixedly connected to the box body 1.

[0027] Finally, the rear end of the above-mentioned mobile platform 10 is fixedly connected to the threaded block 8, and the front parts of both sides of the bottom end of the mobile platform 10 are rotatably connected with the support legs 11, and the bottom ends of the support legs 11 are provided with running wheels 12. Therefore, when the mobile platform 10 is located inside the box cavity 3, the support legs 11 are parallel to the mobile platform 10. At this time, they are stored between the mobile platform 10 and the bottom platform 4. When the motor 26 drives the screw rod 6 to rotate, under the influence of the threaded connection, the threaded block 8 begins to move from the back to the front, thereby driving the mobile platform 10 thereon to start moving. When the part of the mobile platform 10 connected to the support legs 11 moves out of the box body 1, it is naturally lowered vertically under the influence of gravity, and the running wheels 12 are abutted against the ground, thereby supporting the mobile platform 10. The middle bearing of the mobile platform 10 is connected with a rotating shaft 13, and the top and bottom ends of the rotating shaft 13 are respectively fixedly connected with a rotating platform 14 and a turntable 15, and the bottom end of the turntable 15 is provided with a recess 16.

[0028] Embodiment 2:

The bottom end of the bearing portion 20 is fixedly connected with a trapezoidal gear 1 22, and a trapezoidal gear 2 23 meshing with the trapezoidal gear 1 22 is provided at the lower rear end thereof, and a motor 2 24 is fixedly connected to the rear end of the trapezoidal gear 2 23, and the motor 2 24 and the bottom wall of the cavity 19 are connected to each other through a motor seat 25.

[0031] Therefore, when the movable table 10 is located inside the box cavity 3 of the box body 1, the protrusion 21 is engaged with the recess 16. At this time, the motor 24 is started, driving the trapezoidal gear 23 to rotate. Under the influence of the meshing, the trapezoidal gear 1 22 rotates, thereby driving the bearing 20 and the protrusion 21 thereon to rotate, and finally driving the rotating table 14 to rotate, so that the material placed thereon can be heated evenly, thereby improving the sintering quality.

[0032] It should be specially noted here that the components described and identified in the text and drawings of the utility model are the key components constituting the utility model, and the remaining non-key components or obvious prior art components, such as screws, nuts and other connecting components, and technical features similar to the prior art are not shown.

[0033] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
