[0052] In some specific embodiments, please refer to the attached Figure 1 , Fig.11 The rotating column 11 is a tubular structure, and the two ends of the rotating column 11 are respectively connected to the inside of the container 2 and the outside of the container 2. The rotating column 11 is provided with a valve 34, and the valve stem of the valve 34 is connected with a gear 35. One side of the first cover body 3 and the second cover body 4 are respectively connected with a gear ring 36 meshing with the gear 35.

[0053] The specific usage is as follows:

[0054] By turning on the electric hoist 12, the bracket 13 can be driven to rise, and then the lifting plate 10 can be driven to rise, and the first lifting plate 10 and the second support plate 20 can be adjusted to rise. The electric hoist 12 can also stop pulling the lifting plate 10 to release it, and the lifting plate 10 can be lowered by the gravity of the container 2;

[0055] The cooling pool 1 contains cooling water that can circulate and cool the parts that need annealing and cooling.

[0056] If the part is large in size, the lifting plate 10 is lifted, and the container 2 is lifted in cooperation with the first lifting plate 10 and the second supporting plate 20. The sliding plate 17 is driven to slide by opening the first electric push rod 14, and the second supporting plate 20 is horizontally slid in cooperation with the slider 16 to separate the first cover 3 and the second cover 4. The second electric push rod 32 is controlled according to the size of the part to adjust the frame 33 to a roughly appropriate position (when the first cover 3 and the second cover 4 are close, a clamping area can be formed to preliminarily limit the range of the metal part). The metal part to be annealed and cooled is placed between the two frames 33 through an external clamp, and the second cover 4 is moved closer to the first cover 3. When the first cover body 3 and the second cover body 4 are about to be attached, the clamp is taken out. At this time, the metal parts are limited to the inner side of the frame bodies 33 on both sides. At this time, the second rotating ring 28 or the first rotating ring 27 is manually rotated to align the positions of the fixing groove 29 and the fixing column 31. As the first cover body 3 and the second cover body 4 continue to move closer, the fixing column 31 is inserted into the fixing groove 29, so that the first rotating ring 27 and the second rotating ring 28 are linked and fixed together. The guide plate 24 is manually pushed to slide the first curved plate 6 and the second curved plate 7 to open the through hole 37, so as to facilitate the observation of the fixing of the parts. At this time, the frame body 33 can be firmly clamped with the metal parts by opening the second electric push rod 32;

[0057] If the volume of the part is small, when the first cover body 3 and the second cover body 4 are fixed together, when the guide plate 24 is manually pushed to open the through hole 37 of the first curved plate 6 and the second curved plate 7, the metal part to be annealed and cooled can be directly placed between the frames 33 at the position of the through hole 37 by a clamp, and the second electric push rod 32 can be opened to enable the frame 33 to firmly clamp the metal part;

[0058] The container 2 is lowered and completely immersed in the cooling liquid. At this time, the liquid cannot enter the interior of the container 2. At this time, the cooling method is selected according to the type of parts;

[0059] Step (1) When the metal parts in the container 2 are insensitive to the coolant with a large temperature difference, they can be directly cooled quickly by the liquid. The rotation of the drive motor 18 is turned on to drive the rotation of the shaft 19, and the bevel gear 1 21 and the bevel gear 2 22 are cooperated to drive the rotation of the rotating column 11. According to the principle of inertia, the first arc plate 6 is driven to rotate relatively on the first cover body 3. Because the fixing column 31 is inserted into the fixing groove 29, the first rotating ring 27 and the second rotating ring 28 are cooperated to make the second arc plate 7 relatively rotate on the second cover body 4, thereby opening the through hole 37 until the guide is The flow plate 24 and the inner wall of the through hole 37 are against each other, and the magnetic force of the first permanent magnet 25 and the second permanent magnet 26 is overcome at the same time. When the through hole 37 is opened, cooling water enters the container 2 from all sides and from the top and bottom at the same time, and each surface of the metal parts can be almost simultaneously exposed to the cooling liquid, so that different positions of the metal parts are evenly annealed and cooled, and the cooling is more uniform. At the same time, as the rotating column 11 rotates continuously, the container 2 rotates continuously, and the liquid is continuously guided into the container 2 through the function of the flow guide plate 24 to anneal and cool the metal parts, and the metal parts can also be cleaned at the same time.

[0060] In addition, when the first arc plate 6 rotates relatively on the first cover body 3, the gear 35 rotates on the gear ring 36, thereby automatically opening the valve 34. When the cooling liquid continuously enters the container 2, it can continuously flow out through one end of the rotating column 11, forming a circulation effect of the liquid, and continuously allowing the cooling liquid to enter the container 2 to anneal and cool the metal parts, so that the annealing and cooling effect of the metal parts is better;

[0061] Step (2) When the metal parts in the container 2 are sensitive to the coolant with a large temperature difference, when the container 2 is lowered into the coolant, the drive motor 18 is first rotated in the opposite direction to that in the above scheme, driving the rotating column 11 to rotate in the opposite direction. At this time, the guide plate 24 is magnetically attracted to the first cover body 3 or the second cover body 4 through the first permanent magnet 25 and the second permanent magnet 26. When the rotating column 11 rotates, the through hole 37 and the valve 34 will not be opened. As the container 2 rotates, the coolant first cools the cover body and the air inside the cover body, and then indirectly performs preliminary cooling on the metal parts. This process is accelerated as the cover body rotates. After the metal parts are initially cooled, the temperature difference between the metal parts and the external coolant is greatly reduced. The drive motor 18 is rotated in the opposite direction to repeat the process of cooling the coolant entering the container 2 in step 1. By adding an indirect cooling process, cracks caused by rapid cooling of the metal parts can be avoided, and the metal parts can also be cleaned.

[0062] When the metal parts are cooled, the rotation of the container 2 can be stopped temporarily, and the container 2 can be lifted off the liquid surface, and the container 2 can continue to rotate. At this time, the through hole 37 is opened, and air enters the container 2 through the guide plate 24, so as to dry the liquid on the surface of the metal parts.

[0063] After the liquid on the surface of the metal part is blown dry, the second cover body 4 is separated from the first cover body 3, and the part after cooling and annealing is taken out.

[0064] The standard parts used in the present invention can all be purchased from the market, and special-shaped parts can be customized according to the description in the specification and the drawings. The specific connection methods of each part adopt conventional means such as mature bolts, rivets, welding, etc. in the prior art. Machinery, parts and equipment all adopt conventional models in the prior art, and the circuit connection adopts the conventional connection method in the prior art, which will not be described in detail here. The content not described in detail in this specification belongs to the prior art known to professional and technical personnel in this field.

[0065] The present invention and its embodiments are described above, and such description is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if ordinary technicians in the field are inspired by it, without departing from the purpose of the invention, they can design a structure and embodiment similar to the technical solution without creativity, which should belong to the protection scope of the present invention.
