[0002] Cryogenic treatment is a new technology that places the workpiece in a specific, controlled low-temperature environment, causing changes in the microstructure of the material to improve its properties. Due to the altered microstructure at low temperatures, the treated material exhibits macroscopic improvements in wear resistance, dimensional stability, tensile strength, and residual stress. Numerous studies have been conducted by scholars both domestically and internationally on this topic. With the development of cryogenic technology and the improvement of testing methods, research on cryogenic treatment has deepened, extending beyond steel to include powder metallurgy, copper alloys, aluminum alloys, and other non-metallic materials (such as plastics and nylon). Applications span a wide range of industries, including aerospace, precision instruments, friction couples, molds, measuring tools, textile machinery parts, the automotive industry, and military science.

[0022] Please see Figure 1-5 This utility model provides a technical solution:

[0023] In this technical solution, a cooling device for deep cryogenic processing of metal materials includes a cooling box 1. A flexible connection 3 is installed at the top of the cooling box 1, and a frame 2 is installed at the top of the flexible connection 3. The frame 2 can sink into the interior of the frame under the action of power. The cross-sectional area of ​​the frame 2 is smaller than that of the cooling box 1. A bearing plate 10 is installed inside the frame 2. Three fixing rings 11 are equidistantly installed at the bottom of the bearing plate 10. A metal blank tube 9 is installed inside each fixing ring 11. Three fixing seats 8 are installed on the inner walls of both sides of the frame 2. Each fixing seat 8 corresponds to the position of the fixing ring 11. The end of the metal blank tube 9 is installed inside the fixing seat 8. Four telescopic rods 12 are equidistantly installed on the inner wall of the fixing ring 11. Springs 13 are sleeved on the outside of the telescopic rods 12. A support plate 14 is installed at the end of the telescopic rods 12. A cooling brush 15 is installed on the inner wall of the support plate 14. The cooling brush 15 is fitted to the outer wall of the metal blank tube 9.

[0024] In this technical solution, the cooling box 1 is filled with coolant. Three fixing rings 11 installed on the support plate 10 can be used to place the metal blank tube 9 inside the fixing rings 11. Both ends of the metal blank tube 9 are set in the fixing seat 8. The fixing rings 11 can move outside the metal blank tube 9, so that the surface of the tube can be cleaned by the cooling brush 15. The cooling brush 15 can be attached to the metal blank tube 9 by the arrangement of the telescopic rod 12, spring 13 and support plate 14.

[0025] In some technical solutions, the support plate 10 is driven by the drive device 4. There are two drive devices 4, which are symmetrically distributed on both sides with the center line of the support plate 10 as the center. The drive device 4 includes a U-shaped plate 401, two round holes 402, two bearings 403, a threaded rod 404, an L-shaped plate 405, a servo motor 406, a connecting plate 407, and a threaded hole 408.

[0026] U-shaped plate 401 is installed on the side wall of frame 2. Two round holes 402 are respectively opened on both sides of U-shaped plate 401. The outer ring of each bearing 403 is installed in one round hole 402. The two sides of threaded rod 404 are respectively installed in the inner ring of bearing 403. L-shaped plate 405 is installed on the side wall of U-shaped plate 401. Servo motor 406 is installed on L-shaped plate 405. The output shaft of servo motor 406 is installed on threaded rod 404. Threaded hole 408 is opened on connecting plate 407. Threaded rod 404 is sleeved in threaded hole 408. Connecting plate 407 is installed on the side wall of bearing plate 10.

[0027] In this technical solution, both the servo motor 406 and the electric push rod 6 are powered. The flexible connection 3 is made of rubber. The output shaft of the servo motor 406 drives the threaded rod 404 to rotate forward and backward in the U-shaped plate 401 through the bearing 403. The threaded rod 404 rotates forward and backward in the threaded hole 408 on the connecting plate 407, so that the connecting plate 407 drives the bearing plate 17 to move back and forth in the frame 2.

[0028] In some technical solutions, a drain pipe 5 is installed at the lower end of the outer wall of the cooling box 1;

[0029] In this technical solution, a valve is installed in the drain pipe 5 to drain the coolant from the cooling tank 1.

[0030] In some technical solutions, the flexible connection 3 and the cooling box 1 are connected by a snap-fit ​​structure. The snap-fit ​​structure includes snap-fit ​​blocks 16 installed around the bottom of the flexible connection 3. Slots 17 are provided around the top of the cooling box 1. The snap-fit ​​blocks 16 are installed in the slots 17. An elastic element 18 is installed inside the snap-fit ​​blocks 16.

[0031] In this technical solution, the flexible connection 3 is installed on the top of the cooling box 1 by inserting the card block 16 into the card slot 17.

[0032] Working principle: In use, first, place the metal blank tube 9 inside the fixing ring 11 and set both ends inside the fixing seat 8. Then, install the flexible connection to the top of the cooling box 1, control the electric push rod 6 to retract, and the frame 2 moves downward under the action of the flexible connection 3, thereby immersing the metal blank tube 9 in the coolant. After immersion, control the electric push rod 6 to extend, and the output shaft of the servo motor 406 drives the threaded rod 404 to rotate forward and backward in the U-shaped plate 401 through the bearing 403. The threaded rod 404 rotates forward and backward in the threaded hole 408 on the connecting plate 407, causing the connecting plate 407 to drive the bearing plate 10 to move back and forth in the frame 2. At this time, the fixing ring 11 on the bearing plate 10 can move outside the metal blank tube 9, and the burrs on its surface can be removed by the cooling brush 15.
