[0003] As shown in the prior art disclosed in CN217877135U, although this prior art allows the sealing cover to move to one side of the vertical furnace body by setting a lead screw, a guide rod, a sliding plate, and a cylinder, and allows the two L-shaped hanging plates to penetrate into the interior of the vertical furnace body by setting a second lead screw, a second guide rod, a second sliding plate, and a second cylinder, and the distance between the two L-shaped hanging plates can be adjusted by setting a bidirectional screw, a guide rod, and a sliding plate, thus enabling the U-shaped placement plate to be removed from the interior of the vertical furnace body, making it less likely to bump into the sintered utensils and reducing the probability of damage to the utensils, and the setting of a fixing block, a sleeve, a pad, and a second spring can play a shock absorption role, thereby improving the safety of the device. However, the length of the L-shaped hanging plates in this prior art is fixed, and the second cylinder is required to improve the extraction efficiency, which increases the size of the equipment and also results in a fixed downward movement distance of the L-shaped hanging plates, making it unsuitable for larger vacuum sintering furnaces.

[0021] 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.

[0022] Refer to the instruction manual appendix Figure 1-5 This utility model provides a vertical vacuum sintering furnace for alloy sintering, including a base 1 and a furnace body 2 located on top of the base 1. The base 1 is provided with auxiliary components for convenient loading and unloading of workpieces inside the furnace body 2. The auxiliary components include an adjustment seat 3 located on top of the furnace body 2. Two spaced-apart fixed plates 4 are installed at the bottom of the adjustment seat 3. A winding wheel 5 is installed between the two fixed plates 4 via a rotating shaft. A connecting rope 6 is wound around the outside of the winding wheel 5. The bottom end of the connecting rope 6 extends into the interior of the furnace body 2, and a sealing cylinder 7 is installed at the bottom end of the connecting rope 6. An electromagnetic ring 8 is installed inside the bottom end of the sealing cylinder 7. A magnetic column 9 is provided inside the electromagnetic ring 8, and a shelf 10 for placing workpieces is installed at the bottom end of the magnetic column 9. A servo motor 11 for driving the winding wheel 5 is installed on the side of one of the fixed plates 4 away from the winding wheel 5.

[0023] When using the aforementioned furnace body 2 for alloy sintering, the furnace body 2 needs to be sealed. Therefore, support frames 12 are installed at the top of both ends of the base 1. An adjusting rod 13 is installed between the top ends of the two support frames 12 via a bearing, and an adjusting seat 3 is threaded to the outside of the adjusting rod 13. An adjusting plate 14 is threaded to one end of the adjusting rod 13. A U-shaped fixing frame 15 is installed at the bottom of the adjusting plate 14. A cover plate 16 for sealing the furnace body 2 is provided at the bottom of the fixing frame 15, and an electric push rod 17 for adjusting the height of the cover plate 16 is installed at the top of the fixing frame 15. A drive motor 18 is installed on the side of one of the support frames 12 away from the adjusting rod 13. The output shaft of the drive motor 18 passes through the support frame 12 and is fixed together with the adjusting rod 13.

[0024] In this way, the drive motor 18 can drive the adjusting rod 13 to rotate, and the adjusting rod 13 can then drive the adjusting plate 14 to move to the top of the furnace body 2, and make the cover plate 16 on the fixed frame 15 correspond vertically with the furnace body 2. Then, the electric push rod 17 can push the cover plate 16 down to contact the furnace body 2, and the cover plate 16 can seal and close the furnace body 2 to ensure the sealing and stability of the furnace body 2 during the sintering of alloys.

[0025] After the sintering of the alloy in furnace body 2 is completed, the workers need to remove the sintered alloy. This can be done by adjusting rod 13 to move adjusting seat 3 and adjusting plate 14, aligning adjusting seat 3 with furnace body 2 and moving adjusting plate 14 away from furnace body 2. Then, servo motor 11 drives winding wheel 5 to release connecting rope 6, thus placing electromagnetic ring 8 from the encapsulation cylinder 7 into furnace body 2 and fitting it onto the outside of magnetic post 9 on shelf 10. Finally, electromagnetic ring 8 is energized and attracts magnetic post 9, thus connecting encapsulation cylinder 7 and shelf 10 as one unit. Servo motor 11 then drives winding wheel 5 to wind connecting rope 6, achieving the effect of gradually removing shelf 10 from furnace body 2. The connecting rope 6 can be adapted to furnace bodies 2 of different depths, improving the convenience of picking up and placing workpieces.

[0026] To ensure that the encapsulation cylinder 7 can be accurately fitted onto the magnetic post 9, it is necessary to limit the positioning of the encapsulation cylinder 7. Therefore, a connecting plate 20 is installed at the top of the encapsulation cylinder 7, which is sleeved on the outside of the connecting rope 6. Guide rods 21 are installed at both the front and rear tops of the connecting plate 20, and the tops of the guide rods 21 pass through the adjusting seat 3 and extend to the top of the adjusting seat 3. In this way, the connecting plate 20 can be limited by the guide rods 21, ensuring the stability of the connecting plate 20 and the encapsulation cylinder 7 when they move up and down, so that the encapsulation cylinder 7 can be accurately fitted onto the outside of the magnetic post 9.

[0027] Meanwhile, to ensure the stability of the adjusting seat 3 and adjusting plate 14 during displacement, it is necessary to limit their movement. Therefore, positioning rods 19 are provided on both the front and rear sides of the adjusting rod 13. The two ends of the positioning rods 19 are fixed to the two support frames 12 respectively, and the front and rear ends of the adjusting seat 3 and the adjusting plate 14 are respectively sleeved on the outside of the two positioning rods 19. In this way, the two positioning rods 19 can limit the movement of the adjusting seat 3 and adjusting plate 14, ensuring the stability of the adjusting plate 14 and adjusting seat 3 during displacement and preventing the adjusting plate 14 and adjusting seat 3 from tilting during the displacement process.

[0028] To ensure the stability of the furnace body 2 during operation, an directional shell 22 is fitted on the outside of the bottom of the base 1. Multiple spaced spring damping shock absorbers 23 are installed inside the directional shell 22, and the top of the spring damping shock absorber 23 is fixed to the bottom of the base 1. In this way, the spring damping shock absorber 23 can be used to absorb the vibration of the furnace body 2 during operation, so as to avoid excessive impact and affect the use effect of the furnace body 2.

[0029] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
