Description

Technical Field

[0001] This utility model belongs to the field of nut processing technology, specifically relating to an anti-oxidation vacuum heat treatment furnace for electronic nuts. Background Technology

[0002] An anti-oxidation vacuum heat treatment furnace for electronic nuts is a device used to perform vacuum heat treatment on electronic nuts to prevent oxidation and improve their performance. A vacuum system extracts air from the furnace to create a vacuum environment, removing oxygen and nitrogen, thus preventing oxidation reactions with the electronic nuts. Simultaneously, electric heating elements generate heat to heat the nuts to a specific temperature, after which a cooling system cools them, giving the nuts the desired mechanical and physical properties.

[0003] For example, a Chinese patent discloses a vacuum heat treatment furnace (publication number CN221740358 U). This patented technology improves the cooling effect of the metal by installing a cooling device in which the air-cooling component blows outside air onto the metal on the placement plate through a fan. At the same time, the coolant in the coolant tank is sprayed out from the atomizing nozzle in the form of atomizing liquid. However, the fan blows outside air directly into the furnace, which will introduce impurities such as oxygen, moisture, and dust, destroying the vacuum environment and causing the metal workpiece to oxidize. Moreover, the airflow blown by the fan onto the workpiece can easily interfere with the movement trajectory of the atomized liquid droplets, resulting in uneven distribution of liquid on the surface of the workpiece.

[0004] Therefore, this utility model provides an anti-oxidation vacuum heat treatment furnace for electronic nuts. Utility Model Content

A shaft 12 is rotatably connected inside the first inner shell 2. Bearing seats 11 are rotatably connected to both ends of the shaft 12. The two sides of the bearing seats 11 are fixedly connected to the first inner shell 2 and the second inner shell 4, respectively. Three frames 9 are circumferentially connected to the outer side of the shaft 12. A positioning mechanism is provided on the inner side of the frames 9.

[0030] like Figures 5 to 7 As shown, the drive mechanism includes a servo motor 23. One end of the output shaft of the servo motor 23 passes through the interior of the second inner shell 4 and is connected to a first gear 15. The outer side of the first gear 15 is meshed with a second gear 24. The inner side of the second gear 24 is fixedly connected to the shaft 12. When the servo motor 23 is turned on, the connection between the first gear 15 and the second gear 24 facilitates the rotation of the shaft 12 and the three frames 9 distributed circumferentially on the outer side. This helps to ensure that the atomized liquid nitrogen is evenly covered on the surface of the electronic nut, further improving the cooling efficiency.

[0031] like Figures 5 to 7 As shown, the positioning mechanism includes a second wire mesh frame 14, which is fixedly connected to the back of the frame 9. Several positioning rods 19 are connected to the front of the second wire mesh frame 14. A pair of hinges 18 are rotatably connected to the front of the frame 9. A first wire mesh frame 13 is fixedly connected to the outside of the hinges 18. The first wire mesh frame 13 is opened to facilitate the insertion of the electronic nut into the outside of the positioning rods 19, and then the first wire mesh frame 13 is fixed.

[0032] like Figure 6 As shown, a pair of first sleeves 20 are connected to the front side of the frame 9 below the first wire mesh frame 13. A rod 21 is slidably connected inside the first sleeve 20, and a second sleeve 22 is slidably connected to the end of the rod 21. The second sleeve 22 is fixedly connected to the first wire mesh frame 13. By inserting the rod 21 into the first sleeve 20 and the second sleeve 22, the first wire mesh frame 13 can be easily fixed.

[0033] like Figures 5 to 7 As shown, the length of the positioning rod 19 is consistent with the distance between the first wire mesh frame 13 and the second wire mesh frame 14, which facilitates the fixing of the electronic nut.

[0034] like Figure 2 and Figure 4 As shown, a cooling mechanism is provided on the top surface of the inner wall of the vacuum heat treatment furnace body 1.

A rotatable first wire mesh frame 13 is set on the front side of the frame 9. The first wire mesh frame 13 is fixed by the cooperation between the first sleeve 20, the insertion rod 21 and the second sleeve 22, thereby achieving the effect of positioning the electronic nut. Then, the solenoid valve 7 is opened, and under the premise of maintaining vacuum, atomized liquid nitrogen is introduced into the furnace through the high-pressure nozzle 16. The cooling effect is achieved by utilizing the principle of liquid evaporation and heat absorption in a vacuum environment. At the same time, liquid nitrogen itself is an inert medium and does not react chemically with metal, thus eliminating oxidation at the source. At the same time, the servo motor 23 is turned on. Through the connection between the first gear 15 and the second gear 24, the drive shaft 12 and the three frames 9 distributed in the outer ring are easily rotated, which helps to ensure that the atomized liquid nitrogen is evenly covered on the surface of the electronic nut, further improving the cooling efficiency.
