[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Reference Figure 1-6 A constant temperature heating furnace for heat treatment of nickel-titanium wire includes a rectangular constant temperature heating furnace 1. Bottom support columns 3 are fixed at both ends of the bottom of the rectangular constant temperature heating furnace 1. A rectangular sliding seat 4 is slidably connected inside the bottom support column 3. A rectangular sealing door 2 is fixed at the top of one side of the rectangular sliding seat 4. A rectangular embedding box 8 is provided at the bottom of the interior of the rectangular constant temperature heating furnace 1. The rectangular embedding box 8 is close to the rectangular sealing door 2 and fixedly connected to the rectangular sealing door 2. Rotatable vertical rotating columns 6 are provided at both ends of the top of the rectangular embedding box 8. Multiple shelves 7 are provided on the outside of the vertical rotating columns 6. A rotating mechanism for rotating the vertical rotating columns 6 is provided inside the rectangular embedding box 8.

[0023] Both ends of the rectangular sliding seat 4 are fixed with dovetail sliders. The bottom support column 3 has a dovetail groove adapted to the dovetail slider. The rectangular sliding seat 4 and the bottom support column 3 are slidably connected by the cooperation of the dovetail slider and the dovetail groove. By setting the dovetail slider and the dovetail groove, the rectangular sliding seat 4 can slide inside the bottom support column 3, thereby allowing the rectangular sealing door 2 to move to one side of the rectangular constant temperature heating furnace 1. When the rectangular sealing door 2 moves, the shelf 7 can move out of the interior of the rectangular constant temperature heating furnace 1, making it easy to take out the nickel-titanium wire on the top of the shelf 7.

[0024] The rotating mechanism includes a drive motor 5. The drive motor 5 is bolted to one side of the rectangular sealing door 2. A longitudinal rotating column 9 is fixed to the output end of the drive motor 5. A first bevel gear 10 is fixed to the side of the longitudinal rotating column 9 away from the drive motor 5. A second bevel gear 11 is meshed with both ends of one side of the first bevel gear 10. A transverse threaded rod 12 is fixed to one end of the second bevel gear 11.

[0025] The longitudinal rotating column 9 passes through the interior of the rectangular sealing door 2 and is rotatably connected to the rectangular sealing door 2 via a bearing. The bearing allows the longitudinal rotating column 9 to rotate inside the rectangular sealing door 2, and the rotation of the longitudinal rotating column 9 causes the first bevel gear 10 to rotate.

[0026] The two transverse threaded rods 12 have the same thread direction. The transverse threaded rod 12 is close to one end of the rectangular embedded box 8 and is rotatably connected to the rectangular embedded box 8 through a bearing. The rotation of the first bevel gear 10 causes the two second bevel gears 11 to rotate in opposite directions, thereby causing the two transverse threaded rods 12 to rotate in opposite directions.

[0027] Here, the operation of the drive motor 5 causes the longitudinal rotating column 9 to rotate, the rotation of the longitudinal rotating column 9 causes the first bevel gear 10 to rotate, the rotation of the first bevel gear 10 causes the two second bevel gears 11 to rotate in opposite directions, and the rotation of the two second bevel gears 11 causes the transverse threaded rod 12 to rotate, and the two transverse threaded rods 12 rotate in opposite directions.

[0028] The rotating mechanism also includes a transverse moving block 13. The outer side of the transverse threaded rod 12 is threaded with the transverse moving block 13. One side of the transverse moving block 13 is rotatably connected to a transverse rotating plate 14. One end of the transverse rotating plate 14 is rotatably connected to a rectangular rotating plate 15. The rectangular rotating plate 15 is sleeved on the outside of the vertical rotating column 6 and is fixedly connected to the vertical rotating column 6.

[0029] The rectangular insert box 8 has a rectangular slide groove inside. The transverse moving block 13 is located inside the rectangular slide groove and is slidably connected to the rectangular insert box 8 through the rectangular slide groove. The rectangular slide groove allows the transverse moving block 13 to move laterally inside the rectangular insert box 8, so that the rotation of the transverse threaded rod 12 can drive the transverse moving block 13 to move inside the rectangular insert box 8.

[0030] Here, the rotation of the transverse threaded rod 12 allows the transverse moving block 13 to move inside the rectangular embedded box 8. The movement of the transverse moving block 13 causes the rectangular rotating plate 15 to drive the vertical rotating column 6 to rotate through the transverse rotating plate 14. This allows the vertical rotating column 6 to rotate after moving out of the rectangular constant temperature heating furnace 1, so that the shelf 7 can rotate, facilitating the loading and unloading of the nickel-titanium wire at the top of the shelf 7.

[0031] Through a series of designs, the rectangular sealed door 2 can be moved easily, which in turn allows the shelf 7 to be moved out of the interior of the rectangular constant temperature heating furnace 1. The rotation of the vertical rotating column 6 facilitates the neat placement and reasonable classification of the nickel-titanium wires on the top of the shelf 7, making reasonable use of the vertical space of the equipment, avoiding space waste, and improving space utilization.

[0032] Working principle: When the rectangular sliding seat 4 slides inside the bottom support column 3, the vertical rotating column 6 and the shelf 7 can move out of the rectangular constant temperature heating furnace 1. The operation of the drive motor 5 causes the longitudinal rotating column 9 to rotate. The rotation of the longitudinal rotating column 9 causes the first bevel gear 10 to rotate. The rotation of the first bevel gear 10 causes the two second bevel gears 11 to rotate in opposite directions. The rotation of the two second bevel gears 11 causes the transverse threaded rod 12 to rotate, and the two transverse threaded rods 12 rotate in opposite directions.

[0033] The rotation of the transverse threaded rod 12 allows the transverse moving block 13 to move inside the rectangular embedded box 8. The movement of the transverse moving block 13 causes the rectangular rotating plate 15 to rotate through the transverse rotating plate 14, thereby allowing the vertical rotating column 6 to rotate after it moves out of the rectangular constant temperature heating furnace 1. This allows the shelf 7 to rotate, facilitating the loading and unloading of the nickel-titanium wire at the top of the shelf 7.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
