Next, the coolant constant temperature unit in the water storage tank maintains the temperature of the coolant that has absorbed heat. Then, the constant temperature coolant is transported to the upper part of the adjacent region and sprayed by the spray plate. In this process, since the coolant has cooled the cast steel part once before being constant temperature, the temperature difference between the coolant and the cast steel part in the adjacent region is not large after absorbing heat.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] This utility model provides a technical solution: a cooling device for machining high-strength cast steel automotive cylinder blocks. (Please refer to...) Figure 1 , Figure 2 , Figure 3 , Figure 4 The system includes a conveyor belt 12, with guard plates 1 on both sides of the conveyor belt 12. A partition 9 is installed inside the guard plate 1, dividing the guard plate 1 into four areas. A guide bucket 2 is installed below the conveyor belt 12, and a water storage tank 3 is connected to the lower end of the guide bucket 2. A coolant temperature control unit 4 is installed in the water storage tank 3. A conveying pipe 5 is connected to one side of the coolant temperature control unit 4, and a spray plate 6 is installed at the upper end of the conveying pipe 5. A cooling pool 7 is installed behind the guard plate 1, and a conveying pump 8 is installed in the cooling pool 7.

[0025] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 The upper port of the guide bucket 2 is connected to the guard plate 1. The coolant after spraying can return to the water storage tank 3 through the guide bucket 2. The guide bucket 2 is connected to the water storage tank 3 and is located below the adjacent guide bucket 2. The coolant in the water storage tank 3 is then transported to the spray plate 6 above the adjacent area for use. In this way, when the cast steel part passes through the area between the first and last areas of the guard plate 1, the coolant sprays and cools the cast steel part. The coolant that absorbs heat enters the water storage tank 3 connected to the guide bucket 2 at the bottom of the corresponding area and then stores water. The coolant temperature control unit 4 in tank 3 maintains the temperature of the coolant that has absorbed heat, and then transports the temperature-controlled coolant to the upper part of the adjacent area for use through the spray plate 6. During this process, since the coolant has been cooled once before being temperature controlled, the temperature difference between the coolant and the cast steel parts in the adjacent area is not significant after absorbing heat. It is worth mentioning that the coolant circulation in each area between the two areas of the guard plate 1 is from low to high. Therefore, this structure reduces the temperature difference during the cooling process of each area.

[0026] Please see Figure 5The inner side of the guard plate 1 is provided with a limiting sleeve 101, and the end of the partition plate 9 facing the limiting sleeve 101 is equipped with a limiting rod 10. The partition plate 9 is rotatably connected to the limiting sleeve 101 through the limiting rod 10, so that the partition plate 9 has a rotatable effect. The upper port of the limiting sleeve 101 is provided with a movable groove 102. A return coil spring 11 is wound on the limiting rod 10. One end of the inner layer of the return coil spring 11 is connected to the limiting rod 10, and one end of the outer layer of the return coil spring 11 is connected to the inner wall of the movable groove 102. When the cast steel part pushes the partition plate 9 into the area inside the guard plate 1, the partition plate 9 returns to its blocking effect, thereby dividing and blocking each area to prevent coolant from splashing during spraying.

[0027] In the cooling device for machining cast steel cylinder parts of automobile cylinders in this utility model, a cooling device is installed on the conveyor belt 12. The cooling device includes a guard plate 1, and a partition 9 is installed in the guard plate 1. The guard plate 1 is divided into four areas by the partition 9. The number of areas is not limited to four and can be increased or decreased according to the temperature requirements. A guide bucket 2 is installed in each area. A water storage tank 3 is installed at the bottom of the guide bucket 2. A coolant constant temperature unit 4 is installed in the water storage tank 3. The core components of the coolant constant temperature unit 4 include a pump, a water tank, a power supply, a control board, and a heat exchanger. A delivery pipe 5 is connected to the coolant constant temperature unit 4, and a spray plate 6 is installed at the upper end of the delivery pipe. The spray plate 6 is located above the partition area of ​​the guide bucket 2.

[0028] When the cast steel parts are conveyed from one end of the conveyor belt 12 to the other end, the cast steel parts enter the guard plate 1. When the cast steel parts are conveyed from one side of the guard plate 1 to the other side, the conveying mechanism in the coolant constant temperature unit 4 draws the coolant from the water storage tank 3 and conveys it through the conveying pipe 5 to the spray plate 6 to spray the cast steel parts with coolant to cool them down.

[0029] In each region between the two areas of the guard plate 1, the water storage tank 3 connected to the guide bucket 2 is located below the guide bucket 2 on the adjacent side, and the coolant in the water storage tank 3 is transported to the spray plate 6 above the adjacent region for use. In this way, when the cast steel part passes through the region between the two areas of the guard plate 1, the coolant sprays and cools the cast steel part, and the coolant that has absorbed heat enters the water storage tank 3 connected to the guide bucket 2 at the bottom of the corresponding region. Then, the coolant constant temperature unit 4 in the water storage tank 3 performs constant temperature operation on the coolant that has absorbed heat, and then transports the constant temperature coolant to the top of the adjacent region for use through the spray plate 6. In this process, since the coolant has cooled the cast steel part once before being constant temperature, after absorbing heat, the temperature difference between the coolant and the cast steel part in the adjacent region is not much. It is worth mentioning that the coolant circulation in each region between the two areas of the guard plate 1 is from low to high. Therefore, through this structure, the temperature difference in the cooling process of each region is reduced, thereby reducing the power requirement of the coolant constant temperature unit 4.

[0030] In the two areas at the beginning and end of the guard plate 1, the guide bucket 2 in one area is connected to the cooling pool 7. The area connected to the cooling pool 7 can be used as the area for the first cooling of the steel casting. The cooled coolant is transported to the cooling pool 7 through the guide bucket 2. A delivery pump 8 is set at the other end of the cooling pool 7, and the spray plate 6 connected to the delivery pump 8 is set above the other end area away from the cooling pool 7. The cooled coolant performs the final stage of spray cooling on the steel casting. Then, the coolant after the final spray cooling begins to be circulated in multiple areas.

[0031] A limiting sleeve 101 is installed on the inner side of the guard plate 1. A limiting rod 10 is installed on one side of the partition 9 provided on one side of the limiting sleeve 101. The partition 9 is rotatably connected to the limiting sleeve 101 through the limiting rod 10. An movable groove 102 is provided at the upper end of the limiting sleeve 101. A reset coil spring 11 is installed on the limiting rod 10. After the limiting rod 10 is inserted into the limiting sleeve 101, the inner end of the reset coil spring 11 is connected to the limiting rod 10, and the outer end of the reset coil spring 11 is connected to the inner wall of the movable groove 102, so that the partition 9 has a reset effect. When the cast steel part pushes the partition 9 into the area inside the guard plate 1, the partition 9 returns to the blocking effect, thereby dividing and blocking each area to prevent coolant from splashing during spraying.
