Description

Technical Field

[0001] This utility model relates to the technical field of waste heat normalizing devices, specifically a waste heat normalizing device for ductile iron castings. Background Technology

[0002] During residual heat isothermal normalizing, the red-hot iron products are typically spread out one by one, and a fan is used to forcefully cool the castings, increasing the cooling rate and significantly improving the surface hardness while refining the grains. Once the castings have cooled to the isothermal temperature, they are transferred to a heat-insulating device for heat preservation. After a period of heat preservation, the device is opened for air cooling. The metallographic structure and hardness meet the technical requirements. In contrast, during residual heat isothermal normalizing, after the products have cooled, tools such as pliers are needed to transfer them to the heat-insulating device, and then they are removed from the device for natural cooling. This requires a second transfer of the castings, making the operation more cumbersome. Utility Model Content

[0003] The purpose of this invention is to provide a waste heat normalizing device for ductile iron castings to solve the problems mentioned in the background art.

[0006] The insulated box has a heat insulation layer installed inside the side walls, and a support frame is fixedly installed at the bottom of the insulated box.

[0007] The mounting component is installed inside the insulation box. Telescopic rods are installed at the top corners of the support frame. The four telescopic rods are used to support the four top corners of the mounting component and to drive the mounting component to move up and down. A bearing plate is rotatably installed at the middle position of the mounting component to support the casting. A heat insulation plate is rotatably installed on both sides of the bottom surface of the mounting component to shield the area below the bearing plate.

[0008] Ventilation fan one is installed inside the insulation box and located below the mounting component. The ventilation fan one is used to blow air onto the support plate.

[0009] There are two rocker arms, which are rotatably mounted on both sides of the mounting component. The top of each rocker arm has a vertical part, on which multiple ventilation fans are mounted. A heat insulation plate is rotatably mounted on the bottom surface of the vertical part, which can shield the vertical part.

[0010] Furthermore, one end of the insulation plate is rotatably connected to the middle position of the mounting component, and a connecting rod is rotatably installed at the middle position of the other end of the insulation plate. One end of the connecting rod is rotatably installed to the inner wall of the insulation box.

[0011] Furthermore, the insulation plate is semi-circular, and the radius of the insulation plate is greater than the radius of the supporting plate.

[0012] Furthermore, a drive assembly is installed on one side of the mounting component, and the drive assembly is used to drive the support plate to rotate.

By setting up the support plate, when strong cooling is required, the telescopic rod drives the mounting part to rise, the first insulation plate releases its cover on the support plate, and when the rocker arm unfolds, the second insulation plate releases its cover on the second ventilation fan. The second and first ventilation fans are then activated to air-cool the castings on the support plate. When heat preservation is required, the mounting part is moved down, and the two first insulation plates work together to cover the bottom of the support plate. The second insulation plate, pushed by the second connecting rod, covers the vertical part, thus preserving the space between the two rocker arms. When natural cooling is required, the mounting part is moved up, and the second and first ventilation fans are turned off. This device can achieve air cooling, heat preservation, and air cooling of castings without the need for frequent handling of castings. Attached Figure Description

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0025] Please see Figures 1-4 In this embodiment of the present invention, a waste heat normalizing device for ductile iron castings includes an insulation box 100, a ventilation fan 200, a mounting component 300, and a rocker arm 400. The side walls of the insulation box 100 are each provided with a heat insulation layer. A support frame 110 is fixedly installed at the bottom of the insulation box 100. The mounting component 300 is disposed inside the insulation box 100. Telescopic rods 350 are installed at the top corners of the support frame 110, providing support for the four top corners of the mounting component 300. The telescopic rods 350 are used to move the mounting component 300 up and down. A bearing plate 310 is rotatably installed at the middle position of the mounting component 300, serving to support the casting. Insulation plates 340 are rotatably mounted on both sides of the bottom surface of the mounting component 300. The insulation plates 340 are used to shield the area below the support plate 310. A ventilation fan 200 is installed inside the insulation box 100 and located below the mounting component 300. The ventilation fan 200 can blow air onto the support plate 310. There are two rocker arms 400, which are rotatably mounted on both sides of the mounting component 300. A vertical part 410 is provided at the top of the rocker arm 400. Multiple ventilation fans 430 are mounted on the vertical part 410. An insulation plate 420 is rotatably mounted on the bottom surface of the vertical part 410. The insulation plate 420 is used to shield the vertical part 410.

[0026] Specifically, when strong cooling is required, the telescopic rod 350 drives the mounting component 300 to rise, moving it above the insulation box 100. As the mounting component 300 moves upward, the insulation plate 340, pulled by the connecting rod 341, moves upward and deflects downward, releasing its obstruction of the support plate 310. Using a tool, the rocker arms 400 are moved to the sides, causing them to deflect outward and unfold. When the rocker arms 400 unfold, they cause the insulation plate 420 to deflect towards the rocker arms 400, releasing its obstruction of the ventilation fan 430, thus activating the cooling mechanism. The second ventilation fan 430 and the first ventilation fan 200 provide air cooling for the castings on the support plate 310. When heat preservation is required, the mounting part 300 is moved down, and the two insulation plates 340 cooperate to shield the bottom of the support plate 310. The second insulation plate 420, pushed by the second connecting rod 440, shields the vertical part 410, thereby achieving heat preservation of the space between the two rocker arms 400. When natural cooling is required, the mounting part 300 is moved up, and the second ventilation fan 430 and the first ventilation fan 200 are turned off. This device can achieve air cooling, heat preservation and air cooling of the castings without the need for frequent handling of the castings.

[0027] Example 1

[0028] like Figures 4-5 As shown, in this embodiment, one end and the middle position of the insulation plate 340 are rotatably connected to the mounting component 300. A connecting rod 341 is rotatably mounted at the middle position of the other end of the insulation plate 340. One end of the connecting rod 341 is rotatably mounted to the inner wall of the insulation box 100. The insulation plate 340 is semi-circular, and its radius is larger than that of the bearing plate 310. A driving assembly 320 is mounted on one side of the mounting component 300. The driving assembly 320 is used to drive the bearing plate 310 to rotate. 310 includes a drive motor 321 installed at one of the top corners of the mounting component 300. The top of the output end of the drive motor 321 extends upward through the mounting component 300 and is fitted with a gear 322. A gear ring 323 is fixedly installed on the support plate 310. The gear ring 323 meshes with the gear 322. Both sides of one end of the vertical part 410 are rotatably connected to the second connecting rod 440. One end of the second connecting rod 440 is rotatably connected to the mounting component 300. One of the four telescopic rods 350 is an electric lifting rod.

[0029] In this embodiment, when the mounting component 300 moves upward, the insulation plate 340 is pulled by the connecting rod 341. At the same time, the insulation plate 340 moves upward and deflects downward, so that the insulation plate 340 can release its shielding of the support plate 310. During air cooling, the drive motor 321 drives the support plate 310 to rotate through the gear 322 and the gear ring 323, thereby facilitating the ventilation fan 430 to cool the casting around its perimeter, making the cooling of the casting surface more uniform.
