Description

Technical Field

[0001] This invention relates to the field of particle-reinforced aluminum matrix composites, specifically to a remelting and recycling device for high-performance particle-reinforced aluminum matrix composites for automobiles. Background Technology

[0002] Particle-reinforced aluminum matrix composites are the most mature type of metal matrix composites, and small-batch production has been carried out. The reinforcements used in the composites are mainly silicon carbide and aluminum oxide, and also contain a small amount of titanium oxide and titanium boride particles (the particle size is generally around 10 micrometers). The matrix can be pure aluminum, but most of them are various aluminum alloys (including high-performance aluminum-lithium alloys).

[0003] Particle-reinforced aluminum matrix composites have the function of remelting and recycling, and have the advantages of high strength, wear resistance and corrosion resistance during workpiece forming and processing, and have broad application prospects.

[0004] Chinese Patent Publication No. CN217600802U discloses a remelting and recycling device for high-performance particle-reinforced aluminum matrix composite materials for automobiles. Through the set melting mechanism, the material put into the remelting box can be melted by heating plate and stirred by stirring blades. The melting is thorough, and after melting, it can be poured into the cooling box. The remelting and recycling device for high-performance particle-reinforced aluminum matrix composite materials for automobiles, through the set recycling mechanism, can close the sealing plate for rapid cooling after the molten liquid is poured into the cooling box, which saves time.

[0005] Oxidation occurs during the remelting process of high-performance particle-reinforced aluminum matrix composites used in automobiles. Furthermore, a certain amount of gas enters the molten high-performance particle-reinforced aluminum matrix composite during stirring. Additionally, the particles within the molten particle-reinforced aluminum matrix composite, such as silicon carbide particles, have a greater mass than the molten aluminum matrix material, causing them to settle and resulting in uneven particle distribution. This leads to mechanical and physical differences within the same batch of products. Most existing technical solutions lack specific methods to address these issues. Therefore, a remelting and recycling device capable of removing internal gases and homogenizing particles during the remelting of particle-reinforced aluminum matrix composites urgently needs to be developed. Summary of the Invention

In addition, a certain amount of gas will enter the high-performance particle-reinforced aluminum matrix composites in the molten state during the stirring process. Furthermore, in the molten state of the particle-reinforced aluminum matrix composites, the internal particles, such as silicon carbide particles, have a larger mass than the aluminum matrix material in the molten state, so they will sink, resulting in uneven particle distribution and causing mechanical and physical differences in the same batch of products.

[0033] Please see Figure 1-7 This invention provides a technical solution: a remelting and recycling device for high-performance particle-reinforced aluminum matrix composite materials used in automobiles, comprising:

A sealing groove 62 is provided on the top of the sealing seat 61. A sealing ring 63 is slidably connected to the inner cavity of the sealing groove 62. The top of the sealing ring 63 is fixedly connected to the top cover 21. The sealing structure 6 provides a sealing function and improves the sealing ability between the working tank 1 and the top cover structure 2.

[0040] The inert gas conveying structure 7 includes a conveying pipe 71 that runs through the bottom of the inner cavity of the working tank 1. The surface of the conveying pipe 71 is rotatably connected to the working tank 1. The top of the conveying pipe 71 is connected to a diverter seat 72. The surface of the diverter seat 72 is connected to a plurality of discharge pipes 73 arranged in an equal-spaced ring. The top of the diverter seat 72 is rotatably connected to a support frame 74. The surface of the support frame 74 is fixedly connected to the working tank 1. The surface of the conveying pipe 71 is fixedly connected to a plurality of high-temperature resistant vibrating rods 75 arranged in an equal-spaced ring. A motor 76 is fixedly connected to one side of the bottom of the working tank 1. The output shaft of the motor 76 is provided with a transmission structure 77. The bottom of the conveying pipe 71 is rotatably connected to a connecting pipe 78.

[0041] In this invention, the high-temperature resistant vibrating rod 43 and the high-temperature resistant vibrating rod 75 have the same structure. Both the high-temperature resistant vibrating rod 43 and the high-temperature resistant vibrating rod 75 have a vibration generator inside. The bottom of both the high-temperature resistant vibrating rod 43 and the high-temperature resistant vibrating rod 75 have a spherical energy-generating part. By setting the high-temperature resistant vibrating rod 43 and the high-temperature resistant vibrating rod 75, the vibration generator inside both the high-temperature resistant vibrating rod 43 and the high-temperature resistant vibrating rod 75, and the spherical energy-generating part, can amplify the vibration and facilitate the discharge of air bubbles.

[0042] In this invention: a number of support columns 8 are fixedly connected to the bottom of the surface of the working tank 1 in an equally spaced ring.

[0043] In this invention: the air inlet pipe of the second air pump 24 extends to the bottom of the top cover 21 and is connected to a high-temperature resistant telescopic tube 26. The bottom of the high-temperature resistant telescopic tube 26 is connected to the annular absorption seat 41. The high-temperature resistant telescopic tube 26 serves to connect the second air pump 24 and the annular absorption seat 41.

[0044] In this invention: the output end of the electric telescopic rod 25 extends through to the bottom of the top cover 21 and is fixedly connected to the annular absorption seat 41.

[0045] In this invention: the output shaft of motor 22 passes through the inner cavity of the working tank 1 and is fixedly connected to the rotating rod 51.

[0046] In this invention, the bottom of the rotating rod 51 is rotatably connected to the support frame 74.

[0047] In this invention: a drain pipe 9 is connected to one side of the bottom of the working tank 1, and an opening and closing valve is provided on the surface of the drain pipe 9.

[0048] Working principle: When using this invention, the user opens the lifting cylinder 32. The output end of the lifting cylinder 32 drives the top cover 21 to move upward through the transmission seat 34. Then, molten particle-reinforced aluminum matrix composite material is added to the inner cavity of the working tank 1. At this time, the lifting cylinder 32 moves in the opposite direction, the top cover 21 moves downward, and the sealing ring 63 is embedded in the inner cavity of the sealing groove 62 to complete the seal. Then, the air pump 23 is started. The air pump 23 pumps out the air in the inner cavity of the working tank 1, so that the inner cavity of the working tank 1 presents a near-vacuum state, which prevents the particle-reinforced aluminum matrix composite material from oxidizing in the inner cavity of the working tank 1.

[0049] At this time, motor 2 76 starts and drives the conveying pipe 71 to rotate through the transmission structure 77. Inert gas enters the inner cavity of the conveying pipe 71 through the connecting pipe 78. The conveying pipe 71 continuously feeds the inert gas into the molten particle-reinforced aluminum matrix composite material through the diverter seat 72 and the discharge pipe 73. The gas forms bubbles in the molten metal. At this time, the high-temperature vibrating rod 2 75 vibrates and breaks the large bubbles into micro bubbles. The partial pressure of hydrogen in the bubbles is almost zero. Hydrogen atoms in the liquid metal diffuse into the bubbles and are discharged as the bubbles rise. At this time, motor 1 22 starts and the output shaft of motor 1 22 drives the rotating rod 51 to rotate. The rotating rod 51 drives the lifting ring 52 to rotate, which continuously churns the bottom molten metal upward.

[0050] Then the electric telescopic rod 25 is started. The output end of the electric telescopic rod 25 drives the annular absorption seat 41 to move downward and slightly insert into the composite material in the molten state. At this time, the high-temperature vibrating rod 43 vibrates simultaneously, which helps the bubbles to rise. The air pump 24 will start at the same time to form a certain negative pressure, which facilitates the gas to be discharged. Finally, the purpose of removing the air inside the composite material in the molten state and homogenizing the particles inside the composite material is achieved.
