Description

Technical Field

[0001] This utility model relates to the field of high-strength steel processing technology, specifically a rapid cooling device for hot forming of high-strength steel. Background Technology

[0002] High-strength steel possesses excellent properties such as high strength and high toughness, and is widely used in automobiles, aerospace, and machinery manufacturing. Hot forming is a crucial step in the production of high-strength steel; after hot forming, the high-strength steel requires cooling to achieve the desired mechanical properties.

[0003] Currently, the commonly used cooling methods for high-strength steel are mainly natural cooling and forced cooling. Natural cooling is slow and inefficient, and cannot meet the needs of large-scale production. Forced cooling usually uses water spray cooling or air cooling, but existing cooling devices suffer from problems such as uneven cooling, low cooling efficiency, and water waste. For example, existing water spray cooling devices often can only cool one side of the high-strength steel, resulting in inconsistent cooling rates on the upper and lower surfaces, which can easily lead to deformation. At the same time, the working range of the cooling water spray is fixed and cannot be flexibly adjusted according to the size of the high-strength steel. For some small-sized high-strength steel workpieces, the working range of the cooling water spray is not concentrated enough, resulting in water waste. Furthermore, the airflow guidance is poor, and it cannot accurately act on the surface of the high-strength steel.

[0004] Therefore, developing a rapid cooling device for hot forming of high-strength steel that can achieve rapid and uniform cooling, improve cooling efficiency, save water resources, and has a more innovative structure is an urgent problem to be solved. Utility Model Content

[0029] Furthermore, an insulation layer is provided on the inner wall of the cooling box 1. The insulation layer can reduce the temperature loss inside the cooling box 1, improve the cooling efficiency, and at the same time prevent the external ambient temperature from affecting the cooling process inside the cooling box 1.

[0030] Furthermore, a limit block 5 is fixed at the inlet and outlet of the cooling box 1. A movable baffle 4 is provided inside the limit block 5. A through-threaded locking bolt 6 is connected to the limit block 5. The position of the movable baffle 4 on the limit block 5 is fixed by the locking bolt 6. A baffle curtain 3 is fixed on the limit block 5. The baffle curtain 3 is located outside the movable baffle 4. A water-cooling assembly 13 is provided inside the cooling box 1. A set of water-cooling assemblies 13 is provided above and below the conveyor belt 2 conveying high-strength steel. The movable baffle 4 can be adjusted up and down on the limit block 5, thereby adjusting the size of the inlet and outlet of the cooling box 1 to adapt to the size of the high-strength steel, so as to ensure the stability of the working environment inside the cooling box 1 and reduce the adverse effects of the external environment.

[0031] Furthermore, the water-cooling assembly 13 includes a fixed frame 1301, a slide rail 1302, a gear 1303, a slide block 1304, a water collection pipe 1305, a spray head 1306, a water guide hose 1307, an outer tie rod 1308, a sliding sleeve 1309, and a locking bolt 1310. The fixed frame 1301 is fixed at both ends inside the cooling box 1. A slide rail 1302 is provided inside the fixed frame 1301, and a slide block 1304 is slidably connected to the slide rail 1302. Two slide blocks 1304 are symmetrically arranged at the center of the inner side of the fixed frame 1301, and the two slide blocks 1304 are meshed with the same gear 1303. The gear 1303 is mounted on the fixed frame 1301 via bearings, and the slide blocks 1304 are... The system is equipped with a water collection pipe 1305, on which a spray head 1306 is installed. The water collection pipe 1305 is connected to an external cooling water source through a water guide hose 1307. This, along with the movement of the slide block 1304, ensures that the position adjustment of the slide block 1304 is not affected by the water pipe connection, allowing for normal water flow. An external pull rod 1308 is fixed to the end of the slide block 1304. The external pull rod 1308 passes through the cooling box 1, and a sliding sleeve 1309 is fixed at the position where the external pull rod 1308 passes through the cooling box 1. A second locking bolt 1310 is installed on the sliding sleeve 1309. The external pull rod 1308 and the sliding sleeve 1309 are fixed in position by the second locking bolt 1310, ensuring stable spraying operation. The displacement of the two slides 1304 inside the fixed frame 1301 is manually controlled by the external tie rod 1308. Under the transmission action of the gear 1303, the synchronous displacement of the two slides 1304 is ensured, thereby adjusting the working range of the spray head 1306 to make it suitable for high-strength steel of different sizes, ensuring that the cooling water can comprehensively and fully cool the high-strength steel and avoid the waste of water resources.

[0032] Furthermore, the outer tie rod 1308 is provided with a size scale to facilitate the determination of the combined working length of the water collection pipe 1305 on the two slides 1304 by the displacement of the outer tie rod 1308, so as to make it suitable for the size of high-strength steel.

[0033] The cooling box 1 is also equipped with an air-cooling component, which includes a filter screen 7, a ventilation pipe 8 and a fan 9. The cooling box 1 has a ventilation opening. One end of the ventilation pipe 8 is connected to the ventilation opening and the other end is connected to the fan 9. The fan 9 is installed inside the cooling box 1, and the filter screen 7 is installed on the ventilation opening.

[0034] Furthermore, two sets of air-cooling components are symmetrically arranged on the left and right sides of the cooling box 1. The fans 9 in the two sets of air-cooling components are a blower and an exhaust fan, respectively, and both fans 9 are inclined towards the conveyor belt 2 inside the cooling box 1. This enables air-cooling operation at the high-strength steel conveying position, improving cooling efficiency.

[0035] The bottom of the cooling tank 1 is provided with a water guide plate 12, which is set at an angle. The lowest point of the water guide plate 12 is provided with a sludge collection trough 14. The drain outlet 10 and the water outlet 11 are connected on both sides of the cooling tank 1.

[0036] Furthermore, the drain outlet 10 is connected to the bottom of the sludge collection tank 14, and the outlet 11 is located directly above the sludge collection tank 14. When collecting cooling wastewater, impurities carried in the wastewater settle into the sludge collection tank 14 under gravity. The wastewater discharge from the outlet 11 does not affect the solid impurities in the sludge collection tank 14, while the drain outlet 10 can discharge the solid impurities, ensuring efficient wastewater reuse.

[0037] Furthermore, the outlet 11 is connected to the cooling water source via a return water pipe, on which a filtration mechanism and a cooling mechanism are installed. The filtration mechanism includes a filter box, inside which coarse and fine filter screens are sequentially arranged from the inlet to the outlet, effectively filtering impurities in the cooling water and ensuring the cleanliness of the circulating cooling water. The cooling mechanism includes a plate cooler, which has advantages such as high heat transfer efficiency, compact structure, and small footprint, and can quickly reduce the temperature of the circulating water to ensure cooling effect.

[0038] Working principle: When using this high-strength steel hot forming rapid cooling device, the high-strength steel is first conveyed into the cooling box 1 on the conveyor belt 2. Before that, the position of the movable baffle 4 is adjusted according to the height of the high-strength steel on the conveyor belt 2 to determine the size of the inlet and outlet of the cooling box 1. After the position of the movable baffle 4 is determined, the position of the movable baffle 4 is fixed by locking bolt 6 to ensure the stability of the inlet and outlet size of the cooling box 1.

[0039] After the high-strength steel is fed into the cooling box 1 by the conveyor belt 2, it first passes through the water cooling component 13. The water cooling component 13 is installed on both the upper and lower sides of the high-strength steel. The external cooling water source is connected to the water collection pipe 1305 through the water guide hose 1307. The spray head 1306 on the water collection pipe 1305 sprays water on the upper and lower sides of the high-strength steel.

[0040] Simultaneously, based on the dimensions of the high-strength steel, the outer pull rod 1308 is manually pulled, causing the inner slide 1304 of the fixed frame 1301 to move on the slide rail 1302. Under the action of the gear 1303, the two slides 1304 are ensured to move synchronously, and the combined working dimensions of the two water collection pipes 1305 are adjusted to suit the dimensions of the high-strength steel. In this way, the cooling water sprayed from the spray head 1306 on the water collection pipe 1305 can be sprayed all over the high-strength steel, avoiding water waste. Meanwhile, the water sprayed from the water cooling component 13 in the conveyor belt 2 will act on the bottom of the high-strength steel. The conveyor belt 2 adopts a stainless steel mesh chain conveyor belt to ensure that the cooling water can pass through the conveyor belt 2 and act on the bottom of the high-strength steel for water cooling.

[0041] Then, as the high-strength steel is conveyed by the conveyor belt 2, it passes through the air-cooling components. The two sets of fans 9 form a circulating airflow that acts on the high-strength steel, accelerating the evaporation of moisture on the surface of the high-strength steel and improving the cooling efficiency. Finally, the conveyor belt 2 sends the high-strength steel out of the cooling box 1 to complete the cooling work.

[0042] The above describes the working process of the rapid cooling device. Any content not described in detail in this specification is existing technology known to those skilled in the art.

[0043] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
