Description

Technical Field

[0001] The present invention relates to the field of metallurgical annealing, and specifically refers to a cleaning, annealing and cooling device for metal parts. Background Art

[0002] Annealing is a treatment process that slowly heats metal to a certain temperature and then slowly cools it, which can adjust the metal structure and eliminate structural defects.

[0003] Currently, when annealing and cooling parts in a liquid manner, although using a liquid with a lower temperature for annealing and cooling can increase the cooling speed of metal parts, for some parts with high hardness, thin walls, and complex shapes, they are more sensitive to temperature difference changes. Therefore, when using a liquid with a lower temperature for annealing and cooling, it is easy for metal parts to deform or crack. Therefore, it is necessary to design a device that can not only quickly cool metal parts that are not sensitive to large cooling temperature differences, such as thick-walled, low-carbon steel, and stainless steel parts, but also meet the situation where parts with high sensitivity to temperature differences do not want metal parts to deform and crack due to large temperature differences, such as parts with high hardness, thin walls, and complex shapes;

[0004] In addition, currently, when putting metal parts into the cooling liquid, the lower end of the metal part is first put into the liquid, and then the upper end of the metal part is gradually put into the cooling liquid, which easily causes uneven cooling of the upper and lower parts of the metal part.

[0051] In some specific embodiments, the fixing assembly 5 includes a second electric push rod 32 and a frame 33. The inner sides of the first cover 3 and the second cover 4 are respectively connected with a frame 33 through the second electric push rod 32.

[0052] In some specific embodiments, please refer to the attached Figure 1 , Figure 11 , the rotating column 11 is of a tubular structure. The two ends of the rotating column 11 are respectively communicated with the inside and the outside of the container 2. A valve 34 is provided on the rotating column 11. A gear 35 is connected to the valve rod of the valve 34. Tooth rings 36 that mesh with the gear 35 are respectively connected to one side of the first cover 3 and the second cover 4.

[0053] The specific usage method is as follows:

[0054] By turning on the electric hoist 12, the support 13 can be driven to rise, and then the lifting plate 10 can be driven to rise. In cooperation with the first lifting plate 10 and the second support plate 20 for adjustment and rising, it is also possible to stop the traction of the lifting plate 10 by the electric hoist 12 for release, and the lifting plate 10 descends due to the gravity of the container 2;

[0055] The cooling pool 1 contains cooling water that can circulate and cool. When parts that need annealing and cooling need to be placed;

[0056] If the part is relatively large in volume, as the lifting plate 10 rises, the container 2 is driven to rise in cooperation with the first lifting plate 10 and the second support plate 20. By activating the first electric push rod 14 to drive the sliding of the sliding plate 17, the horizontal sliding of the second support plate 20 is achieved in cooperation with the slider 16, separating the first cover body 3 and the second cover body 4. The second electric push rod 32 is controlled according to the size of the part to adjust the frame body 33 to a roughly appropriate position (when the first cover body 3 and the second cover body 4 are close, a clamping area can be formed to initially limit the range of the metal part). The metal part to be annealed and cooled is placed between the two frame bodies 33 by an external clamp. As the second cover body 4 approaches the first cover body 3, when the first cover body 3 and the second cover body 4 are about to fit, the clamp is removed. At this time, the metal part is limited to the inner sides of the two frame bodies 33. Then, by manually rotating the second rotating ring 28 or the first rotating ring 27, the positions of the fixing groove 29 and the fixing column 31 are aligned. As the first cover body 3 and the second cover body 4 continue to approach, the fixing column 31 is inserted into the fixing groove 29, and the first rotating ring 27 and the second rotating ring 28 are linked and fixed together. By manually pushing the guide plate 24, the first arc-shaped plate 6 and the second arc-shaped plate 7 slide to open the through hole 37, facilitating the observation of the fixing situation of the part. At this time, by activating the second electric push rod 32, the frame body 33 can firmly clamp the metal part;

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

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

[0059] Step (1) When the metal parts in the container 2 are not sensitive to the coolant with a large temperature difference, they can be directly cooled rapidly by the liquid. By turning on the driving motor 18 to drive the rotation of the rotating shaft 19, and cooperating with the first bevel gear 21 and the second bevel gear 22 to drive the rotation of the rotating column 11. According to the inertia principle, the first arc-shaped plate 6 is driven to rotate relatively on the first cover 3. Due to the fact that the fixed column 31 is inserted into the fixed groove 29, and cooperating with the first rotating ring 27 and the second rotating ring 28, the second arc-shaped plate 7 also rotates relatively on the second cover 4, thus opening the through hole 37 until the guide plate 24 abuts against the inner wall of the through hole 37, and at the same time overcoming the magnetic force between the first permanent magnet 25 and the second permanent magnet 26. When the through hole 37 is opened, cooling water enters simultaneously around, above and below the container 2, and each surface of the metal parts can be almost simultaneously contacted by the cooling liquid, enabling the metal parts to be annealed and cooled evenly at different positions, with more uniform cooling. At the same time, as the rotating column 11 rotates continuously, the container 2 rotates continuously, and through the action of the guide plate 24, the liquid is continuously guided into the container 2 to anneal and cool the metal parts, and at the same time, the purpose of cleaning the metal parts can also be achieved;

[0060] In addition, when the first arc-shaped plate 6 rotates relatively on the first cover 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 flow out continuously from one end of the rotating column 11, forming a circulating action of the liquid, and continuously making the cooling liquid enter the container 2 to anneal and cool the metal parts, making the annealing and cooling effect of the metal parts 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 descends into the coolant body, first, the driving motor 18 rotates in the opposite direction to the above-mentioned 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 3 or the second cover 4 through the action of 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 and the air inside the cover, and then indirectly cools the metal parts preliminarily. This process is accelerated as the cover rotates. After the metal parts are preliminarily cooled and the temperature difference between the metal parts and the external coolant is greatly reduced, reverse the driving motor 18 and repeat the process of cooling by the coolant entering the container 2 in step 1. By adding an indirect cooling process, cracks generated when the metal parts are cooled rapidly can be avoided, and at the same time, the purpose of cleaning the metal parts can also be achieved;

[0062] After the metal part is cooled, the rotation of the container 2 can be briefly stopped, the container 2 is lifted out of the liquid surface, and the rotation of the container 2 is continued. At this time, the through hole 37 is opened, and air enters the container 2 through the flow guide plate 24 to dry the liquid on the surface of the metal part;

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

[0064] The standard parts used in the present invention can all be purchased from the market. The special-shaped parts can be customized according to the description in the specification and the drawings. The specific connection methods of each part all adopt conventional means such as bolts, rivets, and welding that are mature in the prior art.

What is shown in the drawings is only one of the implementation manners of the present invention, and the actual structure is not limited thereto. Generally speaking, if those of ordinary skill in the art are inspired by it and design similar structural manners and embodiments without creative work without departing from the purpose of the present invention, they shall fall within the protection scope of the present invention.
