The upper right side of the base 1 is connected to the heat treatment furnace 2, the upper rear side of the heat treatment furnace 2 is rotatably connected to the rotary cover 3, and the front side of the heat treatment furnace 2 is connected to the vacuum The air suction port 4 is connected to the upper left side of the base 1 in a sliding manner with a sealed door 5, and the left side of the sealed door 5 is connected to a placement rack 6, which is slidably connected to the heat treatment furnace 2. The left and right front sides of the rotating cover 3 are connected to the first limiting rack 7, and the left and right front sides of the heat treatment furnace 2 are connected to a group of support rods 8, each group consisting of two left and right support rods 8, and the support rods 8 are rotatably connected with screws 9, and the screws 9 are threadedly connected with nuts 10, and the nuts 10 are provided with handles for easy rotation. The nut 10 is in contact with the adjacent first limiting frame 7, and the left side of the base 1 is connected to the motor 11. The output shaft of the motor 11 is connected to the screw rod 12. The screw rod 12 is rotatably connected to the base 1, and the screw rod 12 is threadedly connected to the sealing door 5. The front of the base 1 is connected to the guide rod 13, and the sealing door 5 is slidingly connected to the guide rod 13. The upper sides of the front and rear parts of the sealing door 5 are connected to the extrusion frame 14, and the upper left side of the rotating cover 3 is connected to the support frame 15. The middle part of the support frame 15 of the base 1 is connected to the electric push rod 16. The lower side of the electric push rod 16 is connected to the base 1, and the telescopic end of the electric push rod 16 is connected to the second limiting frame 17. The second limiting frame 17 is slidingly connected to the support frame 15. The front and rear parts of the second limiting frame 17 are connected to the support frame 15 with a telescopic spring 18. The second limiting frame 17 is extruded and matched with the extrusion frame 14. The second limiting frame 17 is clamped with the extrusion frame 14. The right part of the extrusion frame 14 is a conical structure, which is convenient for extrusion with the second limiting frame 17. The second limiting frames 17 are all arc-shaped structures, which are convenient for positioning and fixing the extrusion frame 14 .
[0020] When using the present invention, first move the base 1 to the medical nickel-titanium alloy anti-oxidation treatment area, then start the motor 11 to rotate the screw 12, so that the sealing door 5 moves to the left on the guide rod 13, driving the placement rack 6 to move to the left out of the heat treatment furnace 2, and then place the medical nickel-titanium alloy to be treated on the placement rack 6, and then start the motor 11 again to move the placement rack 6 to the right, so that the medical nickel-titanium alloy moves to the inside of the heat treatment furnace 2, and at the same time close the heat treatment furnace 2 through the sealing door 5. After the sealing door 5 is sealed, the heat treatment furnace 2 is closed. The inside of the heat treatment furnace 2 is drawn into a vacuum state through the vacuum suction port 4, and then the medical nickel-titanium alloy is heated in the heat treatment furnace 2 to prevent the medical nickel-titanium alloy from being oxidized during the heat treatment process. When the motor 11 is started and the sealing door 5 moves in the right direction, the extrusion frame 14 moves to the right, and the second limiting frame 17 is squeezed by the extrusion frame 14, so that the second limiting frame 17 moves upward on the support frame 15, and the telescopic spring 18 is squeezed and contracted. When the sealing door 5 contacts and closes with the heat treatment furnace 2, the telescopic spring 18 rebounds, driving the second limiting frame 17 to move upward on the support frame 15. The limiting frame 17 moves downward to engage the extrusion frame 14, thereby fixing the sealing door 5. After the heat treatment of the medical nickel-titanium alloy is completed, the electric push rod 16 is started, so that the telescopic end of the electric push rod 16 is pushed upward, so that the second limiting frame 17 moves upward and separates from the extrusion frame 14. Then, the motor 11 is started to move the sealing door 5 and the placement frame 6 to the left, and the processed medical nickel-titanium alloy is taken out, thereby facilitating the loading and unloading of the medical nickel-titanium alloy and preventing the sealing door 5 from being opened by mistake during the heating process. When cleaning the heat treatment furnace 2, rotate the nut 10 to disengage the screw 9, then rotate the screw 9 outward to disengage the screw 9 from the first limiting frame 7, and then open the rotating cover 3 to clean the inside of the heat treatment furnace 2. After cleaning, rotate the rotating cover 3 to close the heat treatment furnace 2 again, then rotate the screw 9 to reset, re-tighten the nut 10, and fix the rotating cover 3 on the heat treatment furnace 2, thereby facilitating the cleaning and maintenance of the inside of the heat treatment furnace 2, improving the anti-oxidation treatment effect of nickel-titanium alloy, and increasing the service life of the equipment.
