Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-5 This utility model provides a technical solution: a high-frequency sintering device for soft magnetic ferrite materials, including a sintering furnace 1, a top cover 2, a sintering chamber 3, a gas chamber 4, a base 5, a self-locking wheel 6, a protective seat 7, a limiting block 8, a guide rod 9, a motor 10, an ignition port 11, a handle 12, a first connecting plate 13, a connecting bolt 14, a first reinforcing plate 15, a second connecting plate 16, a second reinforcing plate 17, a pressure relief pipe 18, a pressure relief valve 19, a sealing gasket 20, a connecting frame 21, a connecting bolt 22, a connecting rod 23, a locking rod 24, a stirring plate 25, a connecting seat 26, and a scraper 27.

[0026] Specific examples Figure 1 , Figure 2 , Figure 4 and Figure 5As shown, place the self-locking wheel 6 on the lower side of the base 5 on a horizontal surface, pull the handle 12 on the outside of the sintering furnace 1 to make the self-locking wheel 6 roll on the horizontal surface. When the base 5 and the connected whole on the upper side of the self-locking wheel 6 reach the appropriate position, stop pulling the handle 12. At this time, the self-locking wheel 6 is in a self-locking state. After placing the soft magnetic ferrite material to be sintered inside the sintering chamber 3, align the center of the connecting frame 21 with the upper opening of the sintering furnace 1 with the "U"-shaped longitudinal section. Press the connecting frame 21 so that the left and right sides of the connecting frame 21 rub against the inner wall of the sintering furnace 1, and the connecting frame 21 slides and connects with the sintering furnace 1.

[0027] Pressing the connecting frame 21 continues until the bottom end of the scraper 27 contacts the bottom end of the sintering chamber 3. At this time, the connecting frame 21 is engaged with the sintering furnace 1, and the bottom end of the connecting frame 21 contacts the top end of the sintering chamber 3. The connecting bolt 22 is screwed in horizontally. The connecting bolt 22 has a threaded structure on its outside. When the connecting bolt 22 is screwed in, the connection gap between the connecting frame 21 and the sintering furnace 1 is shortened. The connecting bolt 22 penetrates vertically through the inside of the connecting frame 21, so that the connecting frame 21 is fixed to the sintering furnace 1 by the connecting bolt 22.

[0028] Next, the center of the top cover 2 is aligned with the center of the sintering furnace 1 and pressed down, so that the sealing gasket 20 on the lower side of the top cover 2 extends into the interior of the sintering furnace 1 until the bottom end of the top cover 2 contacts the upper side of the sintering furnace 1. A first connecting plate 13 with a circular structure is provided on the outer side of the top cover 2. A first reinforcing plate 15 with equal angles is provided on the upper side of the first connecting plate 13. The first reinforcing plate 15 has a triangular structure to reinforce the connection between the first connecting plate 13 and the top cover 2. At the same time, a second connecting plate 16 is installed on the outer end of the sintering furnace 1. A second reinforcing plate with a triangular structure is provided on the lower side of the second connecting plate 16. 17 is used to reinforce the connection between the second connecting plate 16 and the sintering furnace 1. When the upper end of the sintering furnace 1 contacts the bottom end of the top cover 2, the lower end of the first connecting plate 13 contacts the upper side of the second connecting plate 16. The connecting bolt 14 is screwed in vertically. The connecting bolt 14 is perpendicular to the first connecting plate 13 and the second connecting plate 16. The connecting bolt 14 has a threaded structure on its outside. After the connecting bolt 14 is tightened, the connecting bolt 14 passes through the interior of the first connecting plate 13 and the second connecting plate 16. The first connecting plate 13 and the second connecting plate 16 are tightly connected, which facilitates the reinforcement and assembly of the high-frequency sintering device for soft magnetic ferrite materials.

[0029] Specific examples Figure 1 and Figure 4As shown, during the assembly of the high-frequency sintering device for soft magnetic ferrite materials, the gas chamber 4 is fitted inside the sintering furnace 1 and encloses the sintering chamber 3 inside the sintering furnace 1. The longitudinal section of the gas chamber 4 has a hollow "U"-shaped structure. The ignition ports 11 are evenly spaced on the gas chamber 4. When gas is introduced into the front of the gas chamber 4, it is ignited under the action of the ignition ports 11. The ignition ports 11 heat the edge of the sintering chamber 3. The pressure relief valve 19 installed inside the pressure relief pipe 18 can be opened to relieve pressure. The pressure relief pipe 18 is located on the upper side of the top cover 2. By setting the heat source of the sintering chamber 3 in multiple directions, the sintering efficiency of the high-frequency sintering device for soft magnetic ferrite materials is improved.

[0030] Specific examples Figure 1 and Figure 3 As shown, a connecting rod 23 is vertically arranged on the lower side of the connecting frame 21. Scrapers 27 are vertically arranged on both the left and right sides of the connecting rod 23. Parallel stirring plates 25 are installed on the upper and lower sides of the scrapers 27. The scraper 27 at the lower end of the connecting rod 23 has a "U" shaped structure. The motor 10 installed inside the protective seat 7 drives the guide rod 9 connected to the upper side to rotate after the motor 10 is powered on. The upper side of the guide rod 9 is connected to the bottom end of the sintering chamber 3, so that the sintering chamber 3 moves with the guide rod 9. The sintering chamber 3 rotates inside the sintering furnace 1. The protective seat 7 at the lower end of the sintering chamber 3 rubs against the limiting block 8. The diameter of the protective seat 7 is larger than that of the limiting block. The diameter of the sintering chamber 3 is 8. The protective seat 7 is slidably connected inside the limiting block 8. Under the action of the ignition port 11, the soft magnetic ferrite material placed inside the sintering chamber 3 is sintered. The stirring plate 25 stirs the sintered material. The stirring plate 25 is set on the outside of the connecting rod 24. The outside of the connecting seat 26 is equipped with a scraper 27. At the same time, the scraper 27 rubs against the inner wall of the sintering chamber 3. The scraper 27 scrapes the connecting rod 23 to prevent the soft magnetic ferrite material from remaining on the inner wall of the sintering chamber 3. This facilitates the scraping function of the high-frequency sintering device for soft magnetic ferrite material. This is the usage method of the high-frequency sintering device for soft magnetic ferrite material.
