DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] Reference Figure 1 - Figure 3 , the utility model provides an embodiment: a cooling device for multi-alloy steel castings, including a box body 1, which serves as the outer shell of the entire cooling device and provides installation and accommodation space for internal components such as a fan 3, a cooling mechanism, a support assembly and a limit assembly. The lower side of the box body 1 is set as a water storage tank, which can collect water flowing down during the spraying process to achieve partial recycling of water resources. The front and rear inner walls of the box body 1 are provided with fans 3, and two groups are provided. By generating airflow, the flow of air around the casting is accelerated. The air flow can take away the heat from the surface of the casting. Combined with spray cooling, it can accelerate the volatilization of water vapor, enhance the cooling effect, and make the cooling more comprehensive and efficient. The inner wall of the box body 1 is provided with a cooling mechanism, which includes a spray assembly and a drive assembly. The drive assembly includes a drive motor 2, which serves as a power source. The rotation of the output shaft of the drive motor 2 drives the placement frame 21 to rotate, so that the casting placed therein can be in full contact with the spray liquid, ensuring that all parts of the casting have the opportunity to be evenly cooled, avoiding local overheating, and improving the cooling quality. The drive motor 2 is arranged on the inner wall of the box body 1.

[0033] Furthermore, a placement frame 21 is provided on the upper side of the output shaft of the driving motor 2 for placing alloy castings of different specifications for cooling. The spray assembly includes a plug-in rod 41 for providing support and positioning. The plug-in rod 41 is plugged into the inner wall of the box body 1. A connecting rod 45 is provided on the outside of the plug-in rod 41 for connecting the plug-in rod 41 with the water pipe 42 to improve the stability of the water pipe 42. At the same time, it is fixed by screws for easy disassembly. The left side of the connecting rod 45 is fixedly connected to the water pipe 42, and the right side is provided with a delivery pipe for delivering external cooling water. The water pipe 45 is provided on the right side for delivering cooling water to the outside. An annular pipe 43 is fixedly connected to the lower side of the casting to transport cooling water. It evenly distributes the cooling water transported from the water pipe 42 to each nozzle 44, so that the cooling water can be sprayed onto the bottom of the casting in a more dispersed and uniform manner, increasing the contact area between the cooling water and the casting and improving the cooling efficiency. A nozzle 44 is provided on the outside of the annular pipe 43 and on the left side of the water pipe 42 to spray cooling water. The cooling effect can be improved by setting the angle of the nozzle 44. Two groups of water pipes 42 are provided, and the other group of water pipes 42 is provided on the left side of the annular pipe 43.

[0034] Reference Figure 2 - Figure 4The driving assembly further comprises a connecting bolt 22 which is slidably arranged in the inner wall of the placing frame 21 and is threadedly connected to the inner wall of the upper side of the output shaft of the driving motor 2, thereby connecting the output shaft of the driving motor 2 and the placing frame 21, which can be quickly disassembled when the device is maintained. The spray head 44 is provided in multiple groups, and the spray head 44 arranged on the outer side of the annular pipe 43 is arranged in an inclined manner, which can increase the spraying area of the bottom surface of the casting, thereby improving the spraying effect of the bottom surface. The upper side of the water pipe 42 is arranged in an inclined manner, which can spray the upper side of the casting, so that the cooling water can better cover different parts of the casting, thereby improving the uniformity of cooling. The connecting rod 45 is provided in multiple groups, and the multiple connecting rods 45 are arranged on the lower side of the annular pipe 43 and are inserted into the inner wall of the box body 1, which are used for fixing the annular pipe 43 and improving the stability of the annular pipe 43.

[0035] Further, the inner wall of the box body 1 is provided with a supporting assembly, which comprises a supporting block 51 for supporting the placing frame 21 and reducing the influence of the weight of the casting on the device. The supporting block 51 is fixedly connected to the inner wall of the box body 1, and the upper inner wall of the supporting block 51 is slidably connected with a ball 52, which can reduce the wear of the parts and prolong the service life of the device. The upper side of the ball 52 is slidably arranged on the outer wall of the lower part of the placing frame 21.

[0036] Referring to Figure 3 Figure 5 The inner wall of the box body 1 near the insertion rod 41 is provided with a limiting assembly, which comprises a pull rod 61 which cooperates with the limiting groove 63 on the right side of the insertion rod 41 to limit the insertion rod 41. The pull rod 61 is slidably connected to the inner wall of the box body 1, and the limiting groove 63 is formed on the right side of the insertion rod 41 and cooperates with the pull rod 61 to limit the insertion rod 41. The pull rod 61 is inserted into the inner wall of the limiting groove 63.

[0037] Further, the pull rod 61 and the box body 1 are elastically connected through a compression spring 62, which connects the outer side of the pull rod 61 and the inner wall of the box body 1 to provide elastic restoring force for the pull rod 61. In the normal state, the compression spring 62 keeps the pull rod 61 inserted into the limiting groove 63 to limit the insertion rod 41. When the insertion rod 41 needs to be operated, an external force overcomes the spring force to move the pull rod 61, thereby facilitating the quick maintenance or replacement of the spraying assembly and improving the maintenance efficiency of the device. The left side and the upper part of the pull rod 61 are arranged in an inclined manner, which facilitates the insertion rod 41 to smoothly push the pull rod 61 to compress the compression spring 62 when the insertion rod 41 is installed. A pull ring is arranged on the right side of the pull rod 61, which facilitates the operator to pull the pull rod 61 and facilitates the installation, disassembly or maintenance operation of the spraying assembly.

[0038] ​Working principle: in use, first in the placing frame 21 for placing the multi-alloy steel casting to be cooled, then start the drive motor 2, while conveying cooling water to the water pipe 42, a group of water pipes 42 conveying cooling water to the annular pipe 43, and then through a plurality of spray heads 44 evenly spraying cooling water to the outside of the casting, so that the cooling water better covers different parts of the casting, ensuring the uniformity of cooling.

[0039] During the cooling process, the two groups of fans 3 arranged on the front and rear sides of the box body 1 work simultaneously, the fans 3 generate air flow to accelerate the flow of air around the casting, and the air flow not only carries away the heat on the surface of the casting, but also can be combined with the spray cooling to accelerate the evaporation of water vapor, further enhance the cooling effect, and make the cooling more comprehensive and efficient.

[0040] At the same time, the upper side of the plurality of support blocks 51 is provided with the ball 52 in contact with the outer wall of the lower side of the upper part of the placing frame 21, and the ball 52 reduces the friction when the placing frame 21 rotates through rolling friction, which not only ensures the stability of the placing frame 21 during rotation, but also reduces the wear of the parts, prolongs the service life of the device, and reduces the influence of the weight of the casting on the device.

[0041] When it is necessary to maintain or replace the spray assembly, the operator can pull the pull ring on the right side of the pull rod 61 to overcome the elastic force of the compression spring 62 to move the pull rod 61, and release the limiting of the plug-in rod 41, so as to facilitate the quick maintenance or replacement of the spray assembly, and improve the maintenance efficiency of the device.

[0042] Finally, it should be pointed out that: the above only for the preferred embodiments of the present application, and not for limiting the present application, although the present application has been described in detail with reference to the foregoing embodiments, for those skilled in the art, it still can modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement for part of the technical features, any modification, equivalent replacement, improvement, etc. within the spirit and principles of the present application, should be included in the protection scope of the present application.
