Description

Technical Field

[0001] This utility model belongs to the field of casting steel cooling technology, specifically relating to a casting steel cooling device. Background Technology

[0002] In the production and manufacturing process of cast steel parts, the cooling process is one of the key steps to ensure the quality of cast steel parts. After the cast steel parts are cast and molded, they need to be cooled down by special cast steel parts cooling equipment to ensure that their mechanical properties and dimensional accuracy meet the design requirements.

[0003] Existing cooling equipment for cast steel parts typically relies on natural cooling or simple water immersion cooling. While these methods achieve cooling, their efficiency is low and cannot meet the demands of large-scale, high-efficiency production. Even when some equipment employs a stirring structure to accelerate the flow of cooling water, the stirring direction is unidirectional, often resulting in localized circulation of the cooling water within the cooling tank. This leads to uneven temperature distribution in the cooling water, with the water temperature rising faster in areas close to the cast steel parts, while other areas cannot receive timely replenishment of cold water, thus affecting the cooling speed and uniformity of the cast steel parts. Utility Model Content

[0004] In view of this, the present invention provides a cooling device for cast steel parts, which can more efficiently agitate the cooling water through the cooperation of a stirring mechanism and a heat exchange component, making the temperature distribution in the cooling water more uniform, avoiding local overheating of the water and affecting the cooling effect of the cast steel parts. At the same time, it can continuously exchange heat with the cooling water, promptly removing the heat absorbed by the cooling water, ensuring that the cooling water always maintains a low temperature, preventing the cold water from rising in temperature due to the inability to exchange heat quickly, and ensuring the continuity of the cooling effect.

[0005] To solve the above-mentioned technical problems, this utility model provides a cooling device for cast steel parts, including a cooling tank, a stirring mechanism, and a heat exchange component disposed within the stirring mechanism. The stirring mechanism includes rotating disks symmetrically rotatably connected to the lower sides of both ends of the inner cavity of the cooling tank. Several connecting rods are provided between the two rotating disks on the same side, and stirring plates are provided on the outer arc surfaces of the connecting rods. This allows for more efficient stirring of the cooling water, resulting in a more uniform temperature distribution in the cooling water. This avoids localized excessively high water temperatures that could affect the cooling effect of the cast steel parts, ensuring rapid cooling of the cast steel parts. It also enables continuous heat exchange of the cooling water, promptly removing the heat absorbed by the cooling water and ensuring that the cooling water always maintains a low temperature. This prevents the cold water from overheating due to insufficient heat exchange, thus ensuring the continuity of the cooling effect.

[0006] Several mixing plates on the same side form a set of mixing components. The mixing directions of the two sets of mixing components are opposite, which ensures the mixing effect.

[0007] The heat exchange assembly includes a transmission head rotatably connected to the outer end of the rotating disk. The rotating disk has a flow distribution cavity, which is connected to the transmission head on the rotating disk. The connecting rod has a transmission cavity, and the two ends of the transmission cavity are connected to the adjacent flow distribution cavity on the same side. The stirring plate has a flow cavity, which is connected to the transmission cavity on the connecting rod. This assembly achieves rapid heat exchange.

[0008] It also includes a drive assembly, which includes a fixed plate located at one end of the cooling box. Both ends of the fixed plate are rotatably connected to rotating rods. The outer ends of the rotating rods are provided with bevel gears. The outer ends of the rotating disks on the cooling box near the bevel gears are provided with bevel gear rings. The bevel gear rings are respectively meshed with the adjacent bevel gears on the same side, that is, the drive rotating disks and their auxiliary mechanisms rotate synchronously in opposite directions.

[0009] The drive assembly also includes a dual-head motor located in the middle of the fixed plate. The output shafts of the dual-head motors are fixedly connected to the inner ends of the adjacent rotating rods on the same side, thus providing synchronous drive.

[0010] It also includes a feeding assembly, which includes a U-shaped frame installed on the cooling box. An electric telescopic rod is installed on the U-shaped frame, and a support frame is provided at the lower end of the telescopic end of the electric telescopic rod, which facilitates the placement of the cast steel parts into the cooling box.

[0011] The feeding assembly also includes guide rods respectively set at both ends of the upper side of the support frame. The guide rods are slidably connected to the corresponding sliding holes on the U-shaped frame, which serve as guides and supports for movement.

[0012] The beneficial effects of the above-mentioned technical solution of this utility model are as follows:

[0013] 1. When the dual-head motor starts, its output shaft drives the rotating rod to rotate. The bevel gear on the rotating rod meshes with the bevel gear ring on the outer side of the rotating disk, thereby driving the symmetrically arranged rotating disk to rotate at both ends of the lower side of the inner cavity of the cooling box. When the rotating disk rotates, the connecting rod and stirring plate on it rotate accordingly. Since several stirring plates on the same side form a group of stirring components and the stirring directions of the two groups of stirring components are opposite, the cooling water can be stirred more efficiently, making the temperature distribution in the cooling water more uniform, avoiding local water temperature being too high and affecting the cooling effect of the cast steel parts, and ensuring rapid cooling of the cast steel parts.

[0014] 2. Connect the inlet of the external heat exchange network to the adjacent transmission head on the same side. The external cooling medium enters the distribution chamber in the rotating disk through the transmission head at one end, and then enters the flow chamber of the stirring plate through the transmission chamber in the connecting rod. During the flow process, the cooling medium exchanges heat with the cooling water and is discharged through the transmission head at the other end. This can continuously exchange heat with the cooling water, remove the heat absorbed by the cooling water in time, ensure that the cooling water always maintains a low temperature, and prevent the temperature of the cold water from rising due to the inability to exchange heat quickly, thus ensuring the continuity of the cooling effect.

[0015] 3. Fill the cooling tank with cooling water, then place the cast steel parts to be cooled onto the support frame. The electric telescopic rod then extends and retracts, causing the support frame to move downwards and place the cast steel parts into the cooling water in the cooling tank. The guide rod on the support frame slides into the sliding hole of the U-shaped frame to ensure that the support frame moves smoothly and facilitates the placement of the cast steel parts into the cooling tank. After cooling, the support frame can reverse and reset, and then continue to drain water. Attached Figure Description

Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the following will be described in conjunction with the accompanying drawings of the embodiments of this utility model. Figure 1-4 The technical solutions of the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.

[0022] This embodiment provides a cooling device for cast steel parts, such as... Figure 1-4 As shown: It includes a cooling box 100, a stirring mechanism, and a heat exchange component disposed within the stirring mechanism. The stirring mechanism includes rotating disks 200 symmetrically rotatably connected to the lower sides of both ends of the inner cavity of the cooling box 100. Several connecting rods 201 are provided between the two rotating disks 200 on the same side. The outer arc surface of the connecting rods 201 is provided with stirring plates 202. Several stirring plates 202 on the same side constitute a set of stirring components. The stirring directions of the two sets of stirring components are opposite.

[0023] Cooling water is poured into the cooling tank 100, and then the cast steel parts to be cooled are placed into the cooling water in the cooling tank 100. The rotating disk 200 rotates, and the connecting rod 201 and the stirring plate 202 on it rotate accordingly. Since several stirring plates 202 on the same side form a group of stirring components and the stirring directions of the two groups of stirring components are opposite, the cooling water can be stirred more efficiently, making the temperature distribution in the cooling water more uniform, avoiding local water temperature being too high and affecting the cooling effect of the cast steel parts, and ensuring that the cast steel parts are cooled quickly.

[0024] like Figure 1-4 As shown, the heat exchange assembly includes a transmission head 300 rotatably connected to the outer end of the rotating disk 200. The rotating disk 200 is provided with a flow distribution cavity 301, which is connected to the transmission head 300 on the rotating disk 200. The connecting rod 201 is provided with a transmission cavity 302, and the two ends of the transmission cavity 302 are connected to the adjacent flow distribution cavity 301 on the same side. The stirring plate 202 is provided with a flow cavity 303, which is connected to the transmission cavity 302 on the connecting rod 201.

[0025] The inlet of the external heat exchange network is connected to the adjacent transmission head 300 on the same side. The external cooling medium enters the diversion chamber 301 in the rotating disk 200 through the transmission head 300 at one end, and then enters the flow chamber 303 of the stirring plate 202 through the transmission chamber 302 in the connecting rod 201. The cooling medium exchanges heat with the cooling water during the flow process and is discharged through the transmission head 300 at the other end. This can continuously exchange heat with the cooling water, remove the heat absorbed by the cooling water in time, ensure that the cooling water always maintains a low temperature, avoid the cold water temperature from rising due to the inability to exchange heat quickly, and ensure the continuity of the cooling effect.

[0026] like Figure 1-3 As shown, it also includes a drive assembly, which includes a fixed plate 400 disposed at one end of the cooling box 100. Both ends of the fixed plate 400 are rotatably connected to rotating rods 401. The outer ends of the rotating rods 401 are provided with bevel gears 402. The outer ends of the rotating disks 200 on the cooling box 100 near the bevel gears 402 are provided with bevel gear rings 403. The bevel gear rings 403 are respectively meshed with the adjacent bevel gears 402 on the same side. The drive assembly also includes a dual-head motor 404 disposed in the middle of the fixed plate 400. The output shafts of the dual-head motor 404 are respectively fixedly connected to the inner ends of the adjacent rotating rods 401 on the same side.

[0027] When the dual-head motor 404 of the drive assembly starts, its output shaft drives the rotating rod 401 to rotate. The bevel gear 402 on the rotating rod 401 meshes with the bevel gear ring 403 on the outer side of the rotating disk 200, thereby driving the symmetrically arranged rotating disk 200 to rotate at both lower sides of the inner cavity of the cooling box 100. When the rotating disk 200 rotates, the connecting rod 201 and the stirring plate 202 on it rotate accordingly, thereby causing the rotating disk 200 and its auxiliary mechanisms to rotate synchronously in opposite directions.

[0028] like Figure 1-2 As shown, it also includes a feeding assembly, which includes a U-shaped frame 500 mounted on the cooling box 100. An electric telescopic rod 501 is mounted on the U-shaped frame 500. A support frame 502 is provided at the lower end of the telescopic end of the electric telescopic rod 501. The feeding assembly also includes guide rods 503 respectively mounted on both ends of the upper side of the support frame 502. The guide rods 503 are slidably connected to the corresponding sliding holes on the U-shaped frame 500.

[0029] The cast steel part to be cooled is placed on the support frame 502. Then, the electric telescopic rod 501 extends and retracts, causing the support frame 502 to move downwards, placing the cast steel part into the cooling water in the cooling box 100. The guide rod 503 on the support frame 502 slides and engages with the sliding hole of the U-shaped frame 500 to ensure that the support frame 502 moves smoothly.

[0030] The working principle of the casting steel cooling device provided by this utility model is as follows: First, cooling water is filled into the cooling tank 100. Then, the casting steel part to be cooled is placed on the support frame 502. Afterward, the electric telescopic rod 501 extends and retracts, driving the support frame 502 to move downward, placing the casting steel part into the cooling water in the cooling tank 100. The guide rod 503 on the support frame 502 slides with the sliding hole of the U-shaped frame 500 to ensure that the support frame 502 moves smoothly. At the same time, the dual-head motor 404 of the drive component starts, and its output shaft drives the rotating rod 401 to rotate. The bevel gear 402 on the rotating rod 401 meshes with the bevel gear ring 403 on the outer side of the rotating disk 200, thereby driving the symmetrically arranged rotating disk 200 to rotate at both lower sides of the inner cavity of the cooling tank 100. When the rotating disk 200 rotates, the connecting rod 201 and the stirring plate 202 on it rotate accordingly. Several stirring plates 202 form a set of stirring components, and the stirring directions of the two sets of stirring components are opposite, which can more efficiently stir the cooling water, make the temperature distribution in the cooling water more uniform, avoid the local water temperature being too high and affecting the cooling effect of the cast steel parts, and ensure the rapid cooling of the cast steel parts. At the same time, the inlet end of the external heat exchange network is connected to the adjacent transmission head 300 on the same side. The external cooling medium enters the diversion chamber 301 in the rotating disk 200 through the transmission head 300 at one end, and then enters the flow chamber 303 of the stirring plate 202 through the transmission chamber 302 in the connecting rod 201. The cooling medium exchanges heat with the cooling water during the flow process and is discharged through the transmission head 300 at the other end. It can continuously exchange heat with the cooling water, remove the heat absorbed by the cooling water in time, ensure that the cooling water always maintains a low temperature, and prevent the temperature of the cold water from rising due to the inability to exchange heat quickly, thus ensuring the continuity of the cooling effect.

[0031] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0032] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
