Description

Technical Field

[0001] This utility model relates to the field of metal heat treatment technology, and in particular to a cooling device for normalizing treatment. Background Technology

[0002] Normalizing is an important heat treatment process for steel materials. It involves heating the steel above its critical point, holding it at that temperature for a period of time, and then cooling it in air to obtain the desired microstructure, thereby improving the material's mechanical and processing properties. Normalized steel exhibits refined grains, a uniform microstructure, and higher hardness, which is crucial for improving the material's strength and toughness. The cooling process, as a key step in normalizing, has a decisive impact on the final product's performance due to its cooling rate and uniformity.

[0003] In the application of cooling equipment for normalizing treatment, traditional cooling methods often have many limitations. Especially in the processing of workpieces requiring rapid and uniform cooling, existing cooling devices are increasingly revealing their limitations. Taking a novel normalizing heat treatment cooling device disclosed in utility model patent CN208395226U as an example, this device includes components such as a hydraulic press, a universal moving fan, an atomizing frame, and a heat treatment loading trolley. Its operation is relatively simple. By introducing cooling into the normalizing process through air mist cooling, it significantly improves the cooling speed while ensuring the normalized metallographic structure, saving time, meeting the production turnover needs of the heat treatment process, and improving the stability and efficiency of heat treatment quality.

[0004] However, while the device improves cooling speed and production efficiency to some extent, it still has some shortcomings in practical use. Specifically, the existing normalizing cooling device lacks a rotation adjustment mechanism for the atomizing frame, making operation inconvenient when rotating the frame. This results in operators needing to spend considerable time and effort adjusting the atomizing frame angle to accommodate workpieces of different shapes or sizes, reducing work efficiency and potentially affecting the uniformity and effectiveness of cooling due to improper adjustments.

[0005] Therefore, given the shortcomings of existing normalizing cooling devices, we urgently need a new normalizing cooling device to address this problem. This device should be able to easily adjust the angle of the atomizing frame to adapt to the processing requirements of different workpieces, while maintaining a high cooling rate and good cooling uniformity, providing strong support for the normalizing treatment of steel materials and further improving the quality and efficiency of heat treatment. Utility Model Content

[0006] The purpose of this invention is to provide a normalizing cooling device that solves the problem that existing normalizing cooling devices do not have a rotation adjustment structure for the atomizing frame, making operation inconvenient when rotating the atomizing frame.

[0007] To achieve the above objectives, this utility model provides a normalizing cooling device, including a base and a heat treatment loading trolley disposed at the center of the top of the base;

[0008] The base has rotating slots on both sides of its top, and each rotating slot has a rotating plate rotatably connected to it through an auxiliary rotating structure.

[0009] Each of the rotating plates is detachably connected to an atomizing frame on its top. One side of the atomizing frame is provided with a mounting frame that is connected to the rotating plate. A movable rod is provided inside the mounting frame. Both ends of the movable rod are slidably connected to the inner wall of the mounting frame. A sliding block is slidably connected to the top of the movable rod. The bottom of the movable rod is connected to the bottom of the inner cavity of the mounting frame through a vertical lifting structure. A fan is provided on the top of the sliding block. The fan is rotatably connected to the top of the sliding block through a mounting sleeve.

[0010] The rotating plate has positioning blocks fixedly connected to both sides of its top, and the atomizing frame has positioning blocks detachably connected to both sides of its bottom.

[0011] The fan is bolted to the inner wall of the mounting sleeve, and the bottom of the mounting sleeve is rotatably connected to the top of the sliding block via a rotating shaft.

[0012] The top of the positioning block has a positioning groove, and the bottom of the atomizing frame is fixedly connected to the inner wall of the positioning groove by a positioning screw.

[0013] The auxiliary rotating structure includes a mounting ring connected to the bottom of the inner cavity of the rotating groove. The top of the mounting ring is connected to several rotating seats, and each rotating seat has a support wheel rotatably connected inside.

[0014] The mounting frame has movable slots on both sides that are adapted to the ends of the movable rods. The vertical lifting structure includes a lifting cylinder connected to the bottom of the inner cavity of the mounting frame. The output end of the lifting cylinder is connected to the bottom of the movable rod.

[0015] This utility model discloses a normalizing cooling device that, by introducing an auxiliary rotating structure, makes the angle adjustment of the rotating plate and the atomizing frame easy and quick, greatly saving the operator's time and effort.

[0023] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0024] Example 1

[0025] Please see Figure 1-5 As shown, a normalizing cooling device according to this embodiment includes a base 1 and a heat treatment loading trolley 3 located at the top center of the base 1. Rotating slots are provided on both sides of the top of the base 1, and a rotating plate 2 is rotatably connected to the inside of each rotating slot through an auxiliary rotating structure. An atomizing frame 4 is detachably connected to the top of each rotating plate 2. An installation frame 5 connected to the rotating plate 2 is provided on one side of the atomizing frame 4. A moving rod 9 is provided inside the installation frame 5. Both ends of the moving rod 9 are slidably connected to the inner wall of the installation frame 5. A sliding block 13 is slidably connected to the top of the moving rod 9. The bottom of the moving rod 9 is connected to the bottom of the inner cavity of the installation frame 5 through a vertical lifting structure. A fan 11 is provided on the top of the sliding block 13. The fan 11 is rotatably connected to the top of the sliding block 13 through an installation sleeve 12.

[0026] First, the steel material requiring normalizing is placed on the heat treatment loading trolley 3 at the center of the top of the base 1. Next, depending on the shape and size of the workpiece, the operator can easily adjust the angle of the rotating plate 2 using an auxiliary rotating structure. This auxiliary rotating structure is located in rotating slots on both sides of the top of the base 1, allowing the rotating plate 2 to rotate flexibly within the slots, thereby adjusting the angle of the detachably connected atomizing frame 4 at its top.

[0027] The adjustment of the atomizing frame 4 is to better adapt to the workpiece and ensure that the mist during the cooling process can evenly cover the workpiece surface. Inside the mounting frame 5, the movable rod 9 plays a crucial supporting and adjusting role. The two ends of the movable rod 9 are slidably connected to the inner wall of the mounting frame 5. This design allows the movable rod 9 to slide up and down within the frame to adjust the relative position between the fan 11 and the atomizing frame 4, further optimizing the cooling effect.

[0028] The sliding block 13 is slidably connected to the top of the moving rod 9, and it supports the fan 11. The fan 11 is rotatably connected to the top of the sliding block 13 via the mounting sleeve 12. This design not only ensures the stable operation of the fan 11, but also allows the fan 11 to adjust its blowing direction when needed, further enhancing the flexibility and uniformity of cooling. When the fan 11 is started, it blows the mist generated by the atomizing frame 4, evenly spraying the cooling medium onto the workpiece to achieve rapid and uniform cooling.

[0029] Meanwhile, the bottom of the moving rod 9 is connected to the bottom of the inner cavity of the mounting frame 5 through a vertical lifting structure. This structure allows the entire fan 11 and atomizing frame system to be adjusted vertically to accommodate workpieces of different heights and ensure maximum cooling effect.

[0030] Throughout the normalizing process, the operator can adjust the angle of the atomizing frame 4, the position and direction of the fan 11, and the height of the moving rod 9 as needed to achieve the best cooling effect.

[0031] Example 2

[0032] Please see Figure 1-5 As shown in this embodiment, a normalizing cooling device has positioning blocks 6 fixedly connected to both sides of the top of the rotating plate 2, and the bottom sides of the atomizing frame 4 are detachably connected to the positioning blocks 6. Specifically, through the structural arrangement of the positioning blocks 6 and the bottom of the atomizing frame 4, operators can use bolts or other connectors to fix the atomizing frame 4 to the positioning blocks 6, achieving quick installation and removal. When it is necessary to replace or clean the atomizing frame 4, the operator only needs to loosen the connectors to remove the atomizing frame 4 from the positioning blocks 6; during installation, the atomizing frame 4 is aligned with the positioning blocks 6 and the connectors are tightened. This achieves the effect of quick replacement and installation of the atomizing frame 4, improving the maintenance efficiency and applicability of the device.

[0033] The top of the positioning block 6 has a positioning groove 7. The bottom of the atomizing frame 4 is fixedly connected to the inner wall of the positioning groove 7 by a positioning screw. Specifically, the positioning groove 7 on the positioning block 6 and the positioning screw at the bottom of the atomizing frame 4 cooperate to achieve precise fixation of the atomizing frame 4 on the positioning block 6. When installing the atomizing frame 4, align the positioning screw with the positioning groove 7 and tighten the screw to firmly fix the atomizing frame 4 on the positioning block 6; when disassembling, simply loosen the bolt and pull out the positioning screw. This achieves the effect of stable installation and accurate positioning of the atomizing frame 4, improving the stability and reliability of the device.

[0034] Example 3

[0035] Please see Figure 1-5 As shown in this embodiment, a normalizing cooling device has a fan 11 bolted to the inner wall of a mounting sleeve 12. The bottom of the mounting sleeve 12 is rotatably connected to the top of a sliding block 13 via a rotating shaft. Specifically, through the cooperative structure of the fan 11, mounting sleeve 12, and sliding block 13, the fan 11 is firmly fixed inside the mounting sleeve 12, while the mounting sleeve 12 can rotate on the sliding block 13 via the rotating shaft. When it is necessary to adjust the airflow direction of the fan 11, the operator only needs to gently rotate the mounting sleeve 12 to drive the fan 11 to rotate as well, thereby adjusting the airflow direction. This achieves the effect of flexible adjustment of the airflow direction of the fan 11, enhancing the uniformity and flexibility of cooling.

[0036] The auxiliary rotation structure includes a mounting ring 15 connected to the bottom of the inner cavity of the rotation groove. Several rotating seats are connected to the top of the mounting ring 15, and each rotating seat has a support wheel 8 rotatably connected inside. Specifically, through the cooperative structure of the mounting ring 15, the rotating seats, and the support wheels 8, the rotating plate 2 can rotate flexibly within the rotation groove. When the angle of the rotating plate 2 needs to be adjusted, the operator only needs to gently push the rotating plate 2, and the support wheels 8 will rotate flexibly within the rotating seats, causing the rotating plate 2 to rotate together. This achieves easy and flexible angle adjustment of the rotating plate 2, improving the convenience and work efficiency of the operator.

[0037] Both sides of the mounting frame 5 are provided with movable slots 10 that are adapted to the ends of the movable rod 9. The vertical lifting structure includes a lifting cylinder 14 connected to the bottom of the inner cavity of the mounting frame 5. The output end of the lifting cylinder 14 is connected to the bottom of the movable rod 9. Specifically, through the cooperation structure of the movable slots 10 on the mounting frame 5 and the lifting cylinder 14, the movable rod 9 can slide up and down within the mounting frame 5. When it is necessary to adjust the relative position between the fan 11 and the atomizing frame 4, the operator only needs to control the extension and retraction of the lifting cylinder 14 to drive the movable rod 9 to slide up and down within the movable slots 10. This achieves the effect of flexible adjustment of the relative position between the fan 11 and the atomizing frame 4, further optimizing the cooling effect and improving the applicability and flexibility of the device.

[0038] This solution includes the following workflow:

[0039] First, the steel material requiring normalizing is placed on the heat treatment loading trolley 3 at the top center of the base 1. Next, depending on the shape and size of the workpiece to be treated, the operator can easily adjust the angle of the rotating plate 2 by pushing the rotating plate 2, causing the support wheel 8 to rotate flexibly within the rotating seat. This, in turn, adjusts the angle of the detachably connected atomizing frame 4 on top of the plate to better accommodate the workpiece.

[0040] Then, the operator can control the extension and retraction of the lifting cylinder 14, causing the moving rod 9 to slide up and down within the moving slot 10 to adjust the relative position between the fan 11 and the atomizing frame 4, further optimizing the cooling effect. Simultaneously, if needed, the operator can also gently rotate the mounting sleeve 12 to rotate the fan 11, adjusting its airflow direction to enhance the uniformity and flexibility of cooling.

[0041] When the fan 11 is started, it blows the mist generated by the atomizing frame 4, evenly spraying the cooling medium onto the workpiece to achieve rapid and uniform cooling. Throughout the normalizing process, the operator can adjust the angle of the atomizing frame 4, the position and direction of the fan 11, and the height of the moving rod 9 as needed to achieve the best cooling effect.

[0042] The beneficial effects are as follows:

[0043] This device, through the cooperation of positioning block 6 and positioning groove 7, enables the rapid installation and disassembly of the atomizing frame 4, improving the maintenance efficiency and applicability of the device. The cooperative structure of mounting ring 15, rotating seat, and support wheel 8 allows for flexible rotation of the rotating plate 2, improving operator convenience and work efficiency. The cooperative structure of moving rod 9, sliding block 13, and lifting cylinder 14 enables flexible adjustment of the relative position of fan 11 and atomizing frame 4, further optimizing the cooling effect. The rotating connection structure of fan 11, mounting sleeve 12, and sliding block 13 allows for flexible adjustment of the fan 11's blowing direction, enhancing the uniformity and flexibility of cooling. In summary, this device has advantages such as reasonable structure, convenient operation, and good cooling effect, and is widely used in the normalizing treatment field.

[0044] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
