Description

Technical Field

[0001] This invention belongs to the field of semi-solid metal processing technology, specifically relating to a modular and replaceable semi-solid slurry cooling channel device. Background Technology

[0002] In the field of semi-solid slurry preparation technology, the cooling trough method is favored due to its common use and low cost. However, traditional cooling troughs mostly adopt an integral structure, which has obvious limitations;

[0003] The material, morphology, and cooling characteristics of the flow channel surface in this integral structure are fixed. When dealing with different alloy systems, such as aluminum alloys, magnesium alloys, and copper alloys, each alloy system has unique thermophysical properties, such as solidification range, heat capacity, and thermal conductivity. Traditional cooling sloping channels cannot select the optimal cooling conditions and interface characteristics for each alloy system based on these differences.

[0004] Specifically, while high thermal conductivity materials are beneficial for nucleation, they may lead to excessively rapid cooling, resulting in a solidified shell. Certain surface shapes can enhance shear forces, but they can also increase flow resistance. Furthermore, when a monolithic structure experiences wear or blockage in the flow channels, the entire device must be replaced, which is not only costly to replace but also extremely inconvenient and inflexible to maintain. Therefore, overcoming these technical problems and shortcomings is a key issue that needs to be addressed. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the prior art where the integral structure must be replaced when the flow channel is worn or blocked. This not only results in high replacement costs and inconvenience in maintenance, but also lacks flexibility. The invention aims to realize a modular and replaceable semi-solid slurry cooling flow channel device.

The end of the U-shaped rod away from the fastener is provided with a thread, and a nut is threadedly connected to the U-shaped rod, with the nut distributed on both sides of the mounting shaft.

[0018] The modular replaceable semi-solid slurry cooling channel device of the present invention will be described in more detail below with reference to the accompanying drawings and specific embodiments.

[0019] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. 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.

[0020] This embodiment discloses a modular, replaceable semi-solid slurry cooling channel device. Through the ingenious design of the fastener 7, connecting plate 3, rotating frame 4, mounting shaft 5, and U-shaped rod 6, a detachable connection between the channel plate 2 and the base plate 1 is achieved. When the working surface of the channel plate 2 is worn or blocked, it is not necessary to replace the entire device; only the channel plate 2 needs to be replaced, significantly reducing operating costs and downtime. (Refer to...) Figures 1-6The main components include a base plate 1, characterized in that: a cooling pipe 8 is installed inside the base plate 1 (the cooling pipe 8 is connected to an external cooling box, and a liquid pump is installed on the cooling pipe 8. During use, the coolant in the cooling box is drawn into the cooling pipe 8, and the coolant flows back into the cooling box after passing through the cooling pipe 8. Since the cooling box and the liquid pump are existing equipment, they will not be described in detail). A flow channel plate 2 is provided at the upper end of the base plate 1. Several fasteners 7 are fixedly connected at even intervals on both sides of the flow channel plate 2. Several connecting plates 3 are fixedly connected at even intervals on both sides of the upper end of the base plate 1. A rotating frame 4 is rotatably installed at the upper end of each connecting plate 3. An installation shaft 5 is rotatably installed on the rotating frame 4. U-shaped rods 6 that can be fastened to the corresponding fasteners 7 are detachably installed at both ends of the installation shaft 5. A limit component 9 is fixedly installed at the upper end of the connecting plate 3 for limiting the rotating frame 4.

[0021] By setting the limiting component 9, the rotating frame 4 can be limited, effectively preventing the base plate 1 and the flow channel plate 2 from shaking due to vibration, causing the U-shaped rod 6 to disengage from the fastener 7, thereby further enhancing the stability of the flow channel plate 2 installation.

[0022] In this embodiment, refer to Figure 1 and Figure 3 The base plate 1 has a groove at the upper middle part that is adapted to the flow channel plate 2 for placing the flow channel plate 2; the side wall of the groove can provide lateral constraint on the flow channel plate 2 to prevent the flow channel plate 2 from rotating at will. The groove provides a reference for repeated positioning of the flow channel plate 2. The operator only needs to put the flow channel plate 2 back into the groove to quickly and accurately restore it to its original installation position, ensuring the consistency of each installation and helping to maintain the stable operation of the device and the stability of the cooling effect. At the same time, the groove design increases the contact area between the flow channel plate 2 and the base plate 1 and makes the contact tighter, which is beneficial for the cooling pipes 8 inside the base plate 1 to cool the slurry well.

[0023] In this embodiment, the cooling pipe 8 is serpentine in shape; this allows the coolant to have a longer contact time with the base plate 1 when flowing in the cooling pipe 8, thus providing more opportunities for heat exchange.

[0024] In this embodiment, the upper surface of the flow channel plate 2 is planar, wavy, or serrated; the base plate 1 and the flow channel plate 2 are both made of copper alloy, mold steel, high thermal conductivity ceramic, or ceramic composite material; by replacing the flow channel plate 2 with different materials and different surface shapes, the cooling rate, nucleation density, shear strength, and flow state of the melt can be precisely controlled, making it widely applicable to the preparation of semi-solid slurries of various metal materials such as aluminum alloy, magnesium alloy, and copper alloy.

[0025] In this embodiment, refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 The end of the U-shaped rod 6 away from the buckle 7 is slidably connected to the mounting shaft 5 through a through hole. The end of the U-shaped rod 6 away from the buckle 7 is threaded, and nuts are threadedly connected to the U-shaped rod 6, with the nuts distributed on both sides of the mounting shaft 5. The design of the nuts and threads allows the U-shaped rod 6 to be disassembled, thus facilitating its periodic replacement. At the same time, the length of the U-shaped rod 6 to the buckle 7 can be adjusted as needed, so that the U-shaped rod 6 can be better fastened to the buckle 7.

[0026] In this embodiment, refer to Figure 1 , Figure 4 , Figure 5 and Figure 6 The limiting component 9 includes a limiting cylinder 901, a limiting rod 902, a sliding plate 903, a spring 904, and a sliding port 905. The limiting cylinder 901 is fixedly connected to the connecting plate 3. A partition is fixedly connected to the center of the limiting cylinder 901. The two ends of the limiting cylinder 901 are slidably connected to the limiting rods 902. A sliding plate 903 is fixedly connected to the end of each limiting rod 902 near the partition. A spring 904 is fixedly connected to the end of each sliding plate 903 near the partition. The end of the spring 904 away from the sliding plate 903 is fixedly connected to the partition. The two ends of the limiting cylinder 901 are provided with sliding ports 905 for the sliding plates 903 to slide left and right. The rotating frame 4 is provided with limiting holes for the limiting rods 902 to be inserted. In practical use, the sliding plate 903 is moved, which drives the limiting rod 902 to move until the limiting rod 902 moves out of the limiting hole. At this time, the rotating frame 4 is rotated as needed. When the rotating frame 4 is reset, the sliding plate 903 is released. Under the action of the spring 904, the sliding plate 903 and the limiting rod 902 are reset, so that the limiting rod 902 is inserted into the limiting hole, limiting the rotating frame 4. This effectively prevents the base plate 1 and the flow channel plate 2 from shaking due to vibration, causing the U-shaped rod 6 to disengage from the fastener 7, thereby further enhancing the stability of the flow channel plate 2 installation.

[0027] In this embodiment, a first magnetic strip is fixedly installed on the buckle 7, and a second magnetic strip that can attract the first magnetic strip is fixedly installed on the U-shaped rod 6. The cooperative design of the first and second magnetic strips further improves the stability of the U-shaped rod 6 on the buckle 7. Simultaneously, the magnetic attraction between the first and second magnetic strips provides automatic guidance and positioning. The operator only needs to bring the U-shaped rod 6 close to the buckle 7; under the magnetic attraction, the U-shaped rod 6 will quickly and accurately adhere to the buckle 7, greatly shortening the installation time and improving installation efficiency.

[0028] The working principle of the modular replaceable semi-solid slurry cooling channel device of the present invention is as follows: When in use, the slurry is placed on the upper end of the channel plate 2 and flows downward. During the flow, the slurry on the channel plate 2 can be solidified by the cooling effect of the cooling pipe 8. When the flow channel plate 2 needs to be replaced, first move the sliding plate 903. The sliding plate 903 drives the limiting rod 902 to move until the limiting rod 902 slides out of the limiting hole. At this time, rotate the rotating frame 4. The rotating frame 4 drives the mounting shaft 5 to move. The mounting shaft 5 drives the U-shaped rod 6 to move, so that the U-shaped rod 6 disengages from the fastener 7, and the flow channel plate 2 is removed from the base plate 1. After removal, place the flow channel plate 2 to be replaced in the groove of the base plate 1, and move the sliding plate 903 in the opposite direction until the limiting hole is reached. Rod 902 does not interfere. Then, rotate the rotating frame 4. With the cooperation of the mounting shaft 5 and the U-shaped rod 6, the U-shaped rod 6 is fastened to the fastener 7. Release the sliding plate 903. Under the action of the spring force of the spring 904, the sliding plate 903 and the limiting rod 902 are reset. The limiting rod 902 is inserted into the limiting hole on the rotating frame 4. At this time, the replacement of the flow channel plate 2 can be completed. It is convenient and quick. There is no need to replace the entire device. Only the flow channel plate 2 needs to be replaced, which greatly reduces the operating cost and downtime.
