Description

Technical Field

[0001] This utility model relates to the field of steel casting processing technology, and in particular to a rapid cooling device for steel castings. Background Technology

[0002] In the production process of cast steel parts, the cooling process is crucial. Rapid and uniform cooling can effectively improve the quality and performance of cast steel parts and reduce defects such as cracks and deformation caused by improper cooling.

[0003] Currently, most existing cooling equipment for large ring-shaped castings has a relatively simple structure and low cooling efficiency, making it difficult to meet the needs of large-scale production. For example, some equipment only uses a single air-cooling or water-cooling method, which cannot achieve multi-directional and efficient cooling; in other equipment, the castings are heated unevenly during the cooling process, resulting in unstable quality of the cooled castings. Therefore, there is an urgent need to design a casting cooling equipment that can achieve rapid and uniform cooling.

[0004] Therefore, this application provides a rapid cooling device for cast steel parts to meet the requirements. Utility Model Content

[0031] As one implementation method in this embodiment, to adapt to the cooling needs of annular castings of different heights, such as Figure 4 , Figure 5 As shown, three sets of sliders 23 are evenly arranged on the inner wall of the cover 2, and a stop block 24 is provided at the bottom of the slider 23.

[0032] As one implementation method in this embodiment, to facilitate the docking of the bottom shell 1 and the cover shell 2 to form a sealed cavity, such as Figures 1 to 4 As shown, the bottom shell 1 has a lower mating plate 11 at the top edge and the cover 2 has an upper mating plate 21 at the bottom edge, with the lower mating plate 11 abutting against the upper mating plate 21.

[0033] As one implementation method in this embodiment, to facilitate the docking of the bottom shell 1 and the cover shell 2 and avoid motion interference, such as Figure 1 , Figure 3 , Figure 5 As shown, the end of the first heat dissipation pipe 4 extends laterally through the side wall of the bottom shell 1, and the top of the cover 2 is provided with a through groove 22, through which the end of the second heat dissipation pipe 5 extends vertically.

[0034] As one implementation method in this embodiment, to ensure uniform heat dissipation of the annular casting 9, such as... Figure 1 As shown, the first ventilation pipe 71 is arranged tangentially along the heat sink 10, and the second ventilation pipe 72 is arranged tangentially along the bottom shell 1.

[0035] As one implementation method in this embodiment, to enhance the air-cooling heat dissipation effect, such as Figure 3 As shown, an air guide column 12 is provided in the hollow slot in the middle of the heat sink 10.

[0036] As one implementation method in this embodiment, to facilitate the hoisting and installation / removal of the cover 2, such as... Figures 1 to 3 As shown, the top of the cover 2 is provided with three sets of evenly arranged hanging rings 25.

[0037] The working principle of this practical device is as follows: First, the annular casting 9 is hoisted onto the heat sink 10. Then, the cover 2 is hoisted above the bottom shell 1 and lowered. During this process, with the cooperation of the slider 23 and the slide groove 32, the stop 24 abuts against the lower part of the slide 31 for limiting the movement. The heat sink ring 3 moves with the cover 2 and is placed onto the annular casting 9. Afterward, the cover 2 continues to fall, the stop 24 separates from the slide 31, and the slider 23 slides downward along the slide groove 32. The second heat sink ring 3... The end of the heat pipe 5 passes through the through groove 22 until the upper connecting plate 21 and the lower connecting plate 11 abut against each other, and the bottom shell 1 and the cover shell 2 form a sealed cavity. Then, the first water inlet multi-port 41 and the second water inlet multi-port 51 are connected to the outlet of the water pump through the tee 6. The first drain multi-port 42 and the second drain multi-port 52 are connected to the water storage tank through the tee 6. The water inlet of the water pump is connected to the water storage tank. Then, the air inlet tee 7 is connected to the air pump to complete the assembly of the equipment.

[0038] When the water pump and air pump are started, cooling water passes through the tee joint 6 and then through the first inlet multi-way joint 41 and the second inlet multi-way joint 51 into the first heat dissipation pipe 4 and the second heat dissipation pipe 5, respectively. The cooling water then passes through the heat dissipation base 10 and the heat dissipation ring 3 to cool the bottom and top of the annular casting 9. After absorbing heat, the cooling water flows back to the water storage tank through the first drain multi-way joint 42 and the second drain multi-way joint 52 for further cooling, achieving water circulation cooling. Simultaneously, air enters the first ventilation pipe 71 and the second ventilation pipe 72 through the air inlet tee 7. The first ventilation pipe 71, tangentially arranged along the heat dissipation base 10, draws air from the first air inlet. Air is fed into the empty slot in the middle of the heat sink 10 through the air guide column 12, the first air guide vane 13, and the second air guide vane 14. The air flows spirally in the empty slot, and the inner side of the annular casting 9 is cooled evenly by air. The second ventilation pipe 72, which is tangentially arranged along the bottom shell 1, sends air from the second air inlet 102 into the gap between the bottom shell 1 and the heat sink 10. Under the guidance of the third air guide vane 15, the air flows spirally and cools the outer side of the annular casting 9. The air that has absorbed heat is discharged from the equipment through the hole 30 in the middle of the heat sink ring 3 and the exhaust pipe 20 on the top of the cover 2.

[0039] When moving the equipment, it can be lifted and moved using the lifting rings 25 evenly distributed on the top of the cover 2, which is convenient to operate.
