Description

Technical Field

[0001] This invention belongs to the field of metal semi-solid preparation technology, specifically relating to an aluminum alloy semi-solid slurry preparation device with vibration and angle adjustment functions. Background Technology

[0002] Since its discovery in the 1970s, semi-solid metal processing technology has been hailed as one of the most promising metal forming technologies of the 21st century. Its core lies in preparing high-quality slurries with a non-dendritic, spherical microstructure. Despite its enormous potential, existing slurry preparation methods (mechanical stirring, electromagnetic stirring, inclined cooling plate methods, etc.) all have significant limitations, hindering their industrial application.

[0003] Mechanical stirring utilizes shear force to break up primary dendrites and promote grain spheroidization. However, it easily attracts oxide inclusions, which can damage material properties. Furthermore, the equipment has high maintenance costs and a limited lifespan; continuous production is difficult to achieve, resulting in low production efficiency. Electromagnetic stirring induces eddy currents in the melt by applying an alternating magnetic field. The interaction between the eddy currents and the magnetic field generates electromagnetic force that drives the melt's movement. However, the initial investment in equipment is huge, and operating energy consumption is high; the complex electromagnetic field environment can interfere with other equipment and operators in the workshop.

[0004] To overcome the high cost and complexity of the aforementioned methods, the tilted cooling plate method has emerged. This method offers simple equipment, low cost, and no pollution; however, it suffers from weak controllability, poor process stability, and a lack of flexibility in its fixed tilt angle design, making it difficult to adapt to diverse process requirements. Therefore, overcoming these technical problems and shortcomings has become a key issue that needs to be addressed. Summary of the Invention

They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0021] Example 1: This embodiment discloses an aluminum alloy semi-solid slurry preparation device with vibration and angle adjustment functions. Through the ingenious design of the gear 5 and the limiting component 6, the angles of the base plate 3 and the flow channel plate 4 can be easily adjusted. In practical applications, the angle of the flow channel plate 4 can be precisely adjusted according to different preparation process requirements, thereby changing the slurry flow state and preparation environment to meet diverse production requirements. (Refer to...) Figures 1-5 The main components include a frame 1, characterized in that: a rotating shaft 2 is symmetrically rotatably connected to the upper middle part of the frame 1, a base plate 3 is fixedly installed between the two rotating shafts 2, and a cooling pipe 9 is installed inside the base plate 3; a flow channel plate 4 is detachably installed on the base plate 3, and a vibration pump 10 is detachably installed at the lower end of the base plate 3; a gear 5 is fixedly installed at one end of one of the rotating shafts 2, and a limiting component 6 for limiting the gear 5 is installed on the frame 1; the limiting component 6 includes a round rod 601, an adjusting frame, and a straight toothed plate 604, the round rod 601 is fixedly connected to the frame 1, and two adjusting frames are symmetrically slidably connected to both sides of the round rod 601, each adjusting frame being equipped with a straight toothed plate 604 that can mesh with the gear 5; through the cooperative design of the base plate 3 and the cooling pipe 9, the melt on the flow channel plate 4 can be solidified, thereby obtaining a semi-solid slurry.

[0022] In this embodiment, the base plate 3 and the flow channel plate 4 are connected by threaded bolts, which facilitates the installation or replacement of the flow channel plate 4.

[0023] In this embodiment, the lower end of the base plate 3 is provided with a plurality of mounting holes spaced apart, and the mounting holes are arranged in a matrix. The mounting holes are connected to the vibration pump 10 by screws. Through the plurality of mounting holes and the matrix arrangement of the mounting holes, the position of the vibration pump 10 can be adjusted as needed, so that the vibration energy can be "customized" according to the flow field and temperature field on the flow channel plate 4, effectively solving the problem of uneven effect caused by fixed-point vibration, thereby obtaining a semi-solid structure with overall uniformity and fine and rounded grains.

[0024] In this embodiment, refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 Each of the adjustment frames includes a sliding block 602, a handle 606, a shaped rod 603, and a limiting rod 605; each sliding block 602 is slidably connected to a round rod 601, a handle 606 is fixedly connected to the lower end of each sliding block 602, and a shaped rod 603 is fixedly connected to the upper end of each sliding block 602. The end of the shaped rod 603 away from the sliding block 602 is fixedly connected to the straight toothed plate 604. A limiting rod 605 is fixedly connected to the frame 1. One end of each sliding block 602... All are fitted onto the limiting rod 605. In actual use, the handle 606 is moved by hand, causing the sliding block 602 to slide on the round rod 601. The sliding block 602 moves the non-circular rod, which in turn moves the spur gear 604 until the spur gear 604 is no longer engaged with the gear 5. At this point, the rotating shaft 2 is rotated as needed. After rotating to the appropriate position, the handle 606 is moved in the opposite direction, and the above steps are repeated to make the spur gear 604 engage with the gear 5, thereby limiting the gear 5 and preventing it from rotating. This completes the locking of the rotating shaft 2.

[0025] Example 2: Based on Example 1, this example discloses an aluminum alloy semi-solid slurry preparation device with vibration and angle adjustment functions, referring to... Figure 1 , Figure 2 , Figure 3 and Figure 4 It mainly includes retaining rings 607 symmetrically fixedly connected to both sides of the round rod 601, and springs 608 sleeved on both sides of the round rod 601. One end of each spring 608 is fixedly connected to the retaining ring 607, and the other end of the spring 608 is fixedly connected to the sliding block 602. With the setting of the springs 608, when the handle 606 is released, the sliding block 602 is reset under the elastic action of the springs 608, thereby causing the spur plate 604 to mesh with the gear 5 and limit the position of the gear 5.

[0026] Example 3: Based on Embodiment 1, this embodiment discloses an aluminum alloy semi-solid slurry preparation device with vibration and angle adjustment functions. It mainly includes a circular rod 601 with threads on its surface (sliding blocks 602 can be slidably sleeved on the threads of the circular rod 601). Both ends of the circular rod 601 are threadedly connected to threaded cylinders that can compress the sliding blocks 602. Through the threaded cylinders, when the spur plate 604 meshes with the gear 5, the threaded cylinders on both sides compress the sliding blocks 602, causing the two sliding blocks 602 to compress each other. This allows the spur plate 604 to mesh with the gear 5, effectively limiting the gear 5 and preventing it from rotating.

[0027] Example 4: Based on Example 1, this example discloses an aluminum alloy semi-solid slurry preparation device with vibration and angle adjustment functions, referring to... Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 It mainly includes the cooling pipe 9 (the cooling pipe 9 is connected to the cooling box, which contains coolant, and a water pump is installed on the cooling pipe 9. In actual use, the water pump draws the coolant from the cooling box into the cooling pipe 9, and after passing through the cooling pipe 9, it finally flows into the cooling box. The cooling box and water pump are not shown in the figure. Since the cooling box and water pump are existing equipment, they will not be described in detail). The shape of the cooling pipe 9 is serpentine. It can extend the residence time of the coolant on the base plate 3, thereby making the cooling effect of the slurry on the flow channel plate 4 better.

[0028] Example 5: The similarities to the above embodiments will not be repeated here, the differences being: This embodiment discloses an aluminum alloy semi-solid slurry preparation device with vibration and angle adjustment functions, referring to... Figure 1 and Figure 2 It mainly includes a protractor 7 fixedly connected to one side of the frame 1, and a pointer 8 fixedly connected to the rotating shaft 2. The pointer 8 and the protractor 7 work together to measure the tilt angle of the rotating shaft 2. By setting the pointer 8 and the protractor 7, the measuring personnel can read the tilt angle of the rotating shaft 2 very intuitively and accurately, avoiding errors caused by estimation or indirect measurement, and obtaining more accurate angle data.

[0029] Example 6: The similarities to the above embodiments will not be repeated here, the differences being: This embodiment discloses an aluminum alloy semi-solid slurry preparation device with vibration and angle adjustment functions. It mainly includes a flow channel plate 4 made of stainless steel. Stainless steel contains alloying elements such as chromium, forming a dense chromium oxide protective film on the surface. This protective film can effectively prevent oxygen, moisture and other chemical substances from contacting the base metal of the flow channel plate 4, thereby preventing corrosion. In addition, stainless steel has high strength and hardness, and can withstand large external forces without deformation or breakage.

[0030] The working principle of the aluminum alloy semi-solid slurry preparation device with vibration and angle adjustment function of the present invention is as follows: When it is necessary to prepare aluminum alloy semi-solid slurry, the vibration pump 10 is installed in a suitable position of the flow channel plate 4 by screws as needed. Then, the two handles 606 are moved away from each other by hand. The handles 606 drive the sliding block 602 to slide, the sliding block 602 drives the irregular rod 603 to move, and the irregular rod 603 drives the straight tooth plate 604 to move until the straight tooth plate 604 is no longer meshed with the gear 5. At this time, the rotating shaft 2 is rotated as needed. The rotating shaft 2 drives the base plate 3 and the flow channel plate 4 to rotate. After adjusting the flow channel plate 4 to a suitable tilt angle, release the handle 606. Under the action of the spring force 608, the sliding block 602 resets, thereby causing the irregular rod 603 and the straight tooth plate 604 to reset, and then the straight tooth plate 604 meshes with the gear 5, thereby limiting the gear 5 and preventing the gear 5 from rotating. Start the vibration pump 10 to pour the aluminum alloy melt onto the surface of the flow channel plate 4. The melt solidifies under the coupling effect of tilting and vibration to obtain a semi-solid slurry.

[0031] In addition, it should be noted that a gear 5 is fixedly installed at one end of another rotating shaft 2, and a limiting component 6 that can limit the rotation of this rotating shaft 2 is installed on the frame. That is, the number of gears 5 and limiting components 6 can be set as needed.
