Description

Technical Field

[0001] The utility model relates to the technical field of metallurgical engineering equipment, in particular to a vacuum melting furnace used for the production of iron-cobalt alloys. Background Art

[0002] Vacuum melting furnaces can provide a high-purity, oxide-free melting environment to improve material quality when producing iron-cobalt alloy materials. They are widely used in aerospace, automobile manufacturing, electronic equipment and other fields. During the alloy production process, it may be necessary to add alloying elements or other additives to the furnace at a specific time to control the chemical composition and properties of the final alloy. Additives are added at specific melting stages to ensure that the alloy meets the required specifications and quality standards. However, when adding quantitative materials, existing vacuum melting furnaces need to repeatedly flip the internal filling pot. During the flipping of the filling pot, the violent movement of the material may cause sputtering, scattering and even increased loss of the material. Utility Model Content

[0003] Purpose of the utility model: In view of the above shortcomings, the utility model provides a vacuum melting furnace for the production of iron-cobalt alloy to solve the above problems existing in the prior art.

[0004] Technical solution: A vacuum melting furnace for producing iron-cobalt alloys, comprising a vacuum chamber, a grinding tool and a filling pot arranged in the vacuum chamber, and also comprising:

[0005] The turning mechanism comprises a connecting rod connected to the outer periphery of the filling pot, and a self-resetting handle fixedly connected to the connecting rod;

[0006] A limiting ring is fixed on the self-resetting handle, and a plurality of limiting grooves are provided on the limiting ring;

DETAILED DESCRIPTION

[0018] In the following description, a large number of specific details are given to provide a more thorough understanding of the utility model. However, it is obvious to those skilled in the art that the utility model can be implemented without one or more of these details. In other examples, in order to avoid confusion with the utility model, some technical features known in the art are not described.

[0019] Reference Figure 1 to Figure 2The utility model provides a vacuum melting furnace for the production of iron-cobalt alloy, the vacuum melting furnace comprises a vacuum chamber 1, a mold 2 is arranged in the vacuum chamber 1, a stuffing pot 3, a flip mechanism 4, a limit ring 5, a connecting plate 6 and a clamping block 7 are also arranged in the vacuum chamber 1. Among them, the flip mechanism 4 comprises a connecting rod 401 connected to the outer periphery of the stuffing pot 3, and a self-resetting handle 402 fixedly connected to the connecting rod 401; the self-resetting handle 402 is a prior art, and a reset device is arranged therein, and after the handle is released, it can automatically return to the initial position. The limit ring 5 is fixed on the self-resetting handle 402, and a plurality of limit grooves 501 are arranged on the limit ring 5; the connecting plate 6 is arranged at the side end of the limit ring 5, and the connecting plate 6 protrudes from one side of the limit ring 5 to form a connecting portion 601; the clamping block 7 is rotatably connected to the connecting portion 601, and a limit end 701 is arranged on the clamping block 7, and when the clamping block 7 is turned, the limit end 701 is in contact with the limit groove 501.

[0020] After the stuffing pot 3 is turned over by the turning mechanism 4, the material is poured into the mold 2 to fill the mold 2. During the filling process, the self-resetting handle 402 rotates the stuffing pot 3. After the filling is completed, the self-resetting handle 402 is released and automatically resets in the reverse direction. The block 7 is set on one side of the limit ring 5 through the connecting plate 6. The block 7 can be rotated at any angle. When in use, the block 7 can be rotated at a certain angle, and the block 7 is close to the limit ring 5. The setting direction and the abutment position of the block 7 are opposite to the flipping and dumping direction of the stuffing pot 3. Then, the force of the reverse reset of the self-resetting handle 402 acts on the limit end 701, and the block 7 blocks the reset of the self-resetting handle 402, and the self-resetting handle 402 will not automatically drive the stuffing pot 3 to flip. After the stuffing pot 3 is filled once, the block 7 abuts against the limit ring 5, and the stuffing pot 3 remains in an inclined state, so that the subsequent stuffing pot 3 can be directly dumped without flipping too much angle, thereby improving the stuffing efficiency.

[0021] The self-resetting handle 402 is arranged inside and outside the vacuum chamber 1, and the limiting ring 5 and the clamping block 7 are arranged outside the vacuum chamber 1. The self-resetting handle 402 passes through the vacuum chamber 1 and is connected to the internal connecting rod 401. The limiting ring 5 and the clamping block 7 both work outside the vacuum chamber 1. According to the working conditions inside the vacuum chamber 1, manual filling can be performed, and the clamping block 7 can be manually pushed to rotate to limit and fix the self-resetting handle 402.

[0022] The block 7 is connected to the limit ring 5 by a connecting shaft 8, and one end of the connecting shaft 8 extends to be fixedly connected to the outer wall of the vacuum chamber 1. The block 7 is limited by the connecting shaft 8 to prevent it from rotating together with the self-resetting handle 402. The block 7 can rotate arbitrarily around the connecting shaft 8. A certain friction coefficient is set between the block 7 and the rotating shaft. When the block 7 is manually pushed to rotate, the block 7 rotates and abuts against the limit ring 5, and the block 7 remains fixed. In addition, the reset force of the self-resetting handle 402 is calculated and customized according to the friction coefficient and the friction between the limit groove 501 and the limit end 701.

[0023] The clamping block 7 includes a top 702 with an arc-shaped curved surface, a curved surface portion 703 recessed toward the middle of the limiting end 701, and a hook-shaped limiting end 701 formed between the curved surface portion 703 and the top 702. The top 702 and one of the curved surface portions 703 facilitate manual pushing of the clamping block 7, and when the limiting end 701 of the other curved surface portion 703 abuts against the limiting groove 501, the other parts of the clamping block 7 are kept away from the limiting ring 5 to avoid interference.

[0024] When the limiting end 701 is located in the limiting groove 501, the limiting groove 501 fits with the limiting end 701. The limiting groove 501 is triangular in shape. When the limiting end 701 is located in the limiting groove 501, the limiting end 701 forms a surface contact with the inner wall of the limiting groove 501 to increase the friction resistance. The limiting end 701 and the connecting shaft 8 have a certain friction coefficient, and then the friction resistance between the limiting end 701 and the connecting shaft 8 is superimposed, which effectively prevents the limiting end 701 from reversing itself under the thrust of the self-resetting handle 402.

[0025] Working principle: Raw materials are added into the filling pot 3, the vacuum chamber 1 is closed, and the materials are heated and melted. The self-reset handle 402 is manually turned, the filling pot 3 is flipped, and the material is added. After adding a certain amount of raw materials, the self-reset handle 402 stops rotating, the block 7 is manually turned, and the limit end 701 of the block 7 extends into the limit groove 501. Release the self-reset handle 402, and under the action of the reset device of the self-reset handle 402, the limit groove 501 and the limit end 701 fit tightly, and the flipping angle of the filling pot 3 is fixed. Push the block 7 in the reverse direction to flip the filling pot 3 again for adding materials. Repeat this process, and when the filling pot 3 is completely flipped, all the raw materials are added, and the feeding work is completed.

[0026] As described above, although the present invention has been shown and described with reference to specific preferred embodiments, it should not be interpreted as limiting the present invention itself. Various changes can be made to it in form and detail without departing from the spirit and scope of the present invention defined in the appended claims.
