[0021] Please see Figure 1-4 This utility model provides the following technical solution: a tempering device for an ultra-large carbide saw blade substrate, comprising a main body box 1, a sealing frame 2 fixedly installed on the front of the main body box 1, a movable shaft 15 movably installed on the right side of the sealing frame 2, an external box door 3 movably installed on the surface of the movable shaft 15, a protective box 12 fixedly installed on the top of the main body box 1, a blower fixedly installed inside the protective box 12, a first diverter pipe 7 fixedly installed at the outlet of the blower, an inlet pipe 6 fixedly installed on the left side of the first diverter pipe 7, an inlet port 16 fixedly installed at the bottom of the inlet pipe 6, and a return port 17 fixedly installed at the inlet of the blower.

A push-pull plate 24 is fixedly installed on the right side of the tension rod 23. A first reinforcing plate 26 is fixedly installed on the left side of the tension rod 23. A return spring 25 is installed on the outside of the push-pull plate 24 and is fixedly connected to the fixing plate 22. A second reinforcing plate 27 is fixedly installed inside the left side of the fixing plate 22.

[0022] Working principle: A sealing frame 2 is installed on the surface of the main body box 1. A movable shaft 15 is installed on the right side of the sealing frame 2. An outer box door 3 is movably installed on the outside of the movable shaft 15. A handle 28 is fixedly installed on the right side of the outer box door 3. The handle 28 is cylindrical in shape, thicker at the top and thinner at the bottom. An inner box door 5 is installed on the left side of the outer box door 3. A sealing ring 4 is installed on the inner box door 5. Through the movable shaft 15 and the ergonomic handle 28, the heavy-duty door can be easily operated with one hand. Through the double-door design, the sealing ring 4 forms a dynamic airtight barrier by self-expansion at high temperature, which can simultaneously block radiant heat. A protective box 12 is installed on the top of the main body box 1. A second cover plate 14 is installed on the top of the protective box 12. The top of the second cover plate 14 is fixed. A blower is fixedly installed inside the protective box 12 with fixing screws 13. A first diverter pipe 7 is fixedly installed at the blower's outlet. An air inlet pipe 6 is fixedly installed on the left side of the first diverter pipe 7. An air inlet 16 is fixedly installed at the bottom of the air inlet pipe 6. An air return port 17 is fixedly installed at the blower's air inlet. An air return pipe 8 is fixedly installed on the left side of the air return port 17. Arc-shaped air guide plates 10 are fixedly installed on both sides of the isolation layer 9. The protective box 12 integrates a blower circulation system. The first diverter pipe 7 / air inlet pipe 6 / air return pipe 8 can physically isolate the blower from high temperature corrosion. At the same time, it can force hot air to penetrate the gap of the saw blade base through a directional airflow circulation path. It also works in conjunction with the air return pipe 8 to achieve efficient recovery of waste heat. Plate 10 forms a turbulent, uniform circulating field, which can effectively eliminate local overheating and cold zones, thereby ensuring the consistency of tempering performance of the ultra-large saw blade substrate and significantly reducing the overall energy consumption of the equipment. The main body box 1 is fixedly installed with a first insulation layer 18, and a second insulation layer 19 is installed on the first insulation layer 18. The double-layer insulation structure can significantly enhance the heat insulation effect, thereby effectively suppressing heat loss and reducing the temperature of the equipment shell, ensuring operational safety and achieving energy saving and consumption reduction. An isolation layer 9 is installed inside the main body box 1, and an electric heating tube 21 is installed inside the isolation layer 9. A first cover plate 11 is installed on the front of the isolation layer 9, and rivets 20 are riveted to the surface of the first cover plate 11. This riveting structure can achieve rapid connection of the first cover plate 11. The quick disassembly significantly improves maintenance efficiency while ensuring operational safety. A fixing plate 22 is fixedly installed at the bottom of the inner wall of the main body box 1. A hole is formed on the right side surface of the fixing plate 22, and a tension rod 23 is movably installed inside the hole. A push-pull plate 24 is fixedly installed on the right side of the tension rod 23, and a first reinforcing plate 26 is fixedly installed on the left side of the tension rod 23. A return spring 25 is installed on the outside of the push-pull plate 24 and is fixedly connected to the fixing plate 22. A second reinforcing plate 27 is fixedly installed inside the left side of the fixing plate 22. This structure adopts a two-way clamping design, ensuring the saw blade remains stable during tempering, effectively preventing displacement and deformation, and solving the problem of insecure fixing in traditional processes. All electrical equipment in this device is powered by an external power source.

[0023] In one aspect of this embodiment, a handle 28 is fixedly installed on the right side of the outer door 3. The cylindrical handle 28, which is thicker at the top and thinner at the bottom, is ergonomically designed to facilitate the operator's application of force, while also enhancing grip stability and improving the efficiency of opening and closing the door. An inner door 5 is fixedly installed on the left side of the outer door 3. Sealing rings 4 are fixedly installed around the inner door 5. The double-layer door structure, together with the sealing rings 4, forms multiple sealing barriers, which can effectively reduce heat loss and thus ensure the temperature uniformity and stability of the tempering chamber.

[0024] In one aspect of this embodiment, a second cover plate 14 is installed on the top of the protective box 12, and a fixing screw 13 is fixedly installed on the top of the second cover plate 14. The modular design of the second cover plate 14 can be quickly disassembled and assembled by the fixing screw 13, which facilitates the maintenance and repair of the blower and pipeline, and reduces the difficulty of equipment maintenance. A first insulation layer 18 is fixedly installed inside the main body box 1, and a second insulation layer 19 is fixedly installed inside the first insulation layer 18. The double-layer insulation structure significantly improves the heat insulation performance, reduces heat loss, and can reduce the temperature of the outer wall of the equipment, thereby ensuring operational safety and saving energy.

[0025] In one aspect of this embodiment, a first cover plate 11 is installed on the front of the isolation layer 9. Rivets 20 are riveted to the surface of the first cover plate 11. The first cover plate 11, which is fixed by the rivets 20, has a stable structure, which makes it resistant to high temperature deformation and facilitates the maintenance and replacement of the heating element 21, thereby extending the service life of the core heating component. Arc-shaped air guide plates 10 are fixedly installed on both sides of the isolation layer 9. The arc-shaped air guide plates 10 can optimize the airflow path, so that hot air circulates evenly on the surface of the saw blade substrate, effectively eliminating the tempering dead zone and improving the consistency of heat treatment.

[0026] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model.
