[0020] Referring to Figures 1-4 , an embodiment of a tunnel-type spring constant temperature tempering furnace of the present utility model includes: a furnace body. The furnace body includes a support plate 1. The upper surface of the support plate 1 is fixedly connected with a top plate 4. The top plate 4 is fixed. The side surface of the top plate 4 is fixedly connected with a baffle plate 16 to prevent heat dissipation. Two fixed plates 2 are fixedly connected to the side surface of the furnace body. A rotating shaft 7 is rotatably connected to the fixed plate 2 to facilitate the rotation of the rotating shaft 7. A sprocket 14 is fixedly connected to the side surface of the rotating shaft 7 to drive the sprocket 14 to rotate. A chain 8 is arranged on the side surface of the sprocket 14. A mesh conveyor belt 9 is fixedly connected to the side surface of the chain 8 to drive the mesh conveyor belt 9 to rotate. A stop block 10 is fixedly connected to the mesh conveyor belt 9 to block the spring.

[0021] A motor 3 is fixedly connected to the side surface of the fixed plate 2. The output end of the motor 3 is fixedly connected to one end of the rotating shaft 7 to drive the rotating shaft 7 to rotate. An exhaust port is provided on the top plate 4. A fan 15 is arranged in the exhaust port to suck out the flue gas in the furnace body. An air purification box 5 is fixedly connected to the upper surface of the top plate 4. The air purification box 5 is located directly above the fan 15 to purify the flue gas. An exhaust duct 6 is fixedly connected to the side surface of the air purification box 5 to discharge the purified flue gas. A heating pipe 12 is fixedly connected to the side surface of the support plate 1. A temperature sensor 13 is arranged below the heating pipe 12 to detect the temperature. The temperature sensor 13 is fixedly connected to the side surface of the support plate 1 and is electrically connected to the heating pipe 12 to facilitate controlling the temperature of the heating pipe 12.

[0022] Working principle: During use, place the spring between two stoppers 10 on the mesh conveyor belt 9. The motor 3 drives the rotating shaft 7 to rotate, causing the mesh conveyor belt 9 to rotate. The spring enters the furnace body, and the heating tube 12 heats and tempers the spring. The temperature sensor 13 detects the temperature. When the temperature is too high, it controls the heating tube 12 to stop heating. After heating, the spring falls into the collection box 11 for collection when it continues to move on the mesh conveyor belt 9. The harmful flue gas in the furnace body is transported to the air purification box 5 by the blower 15 for purification and finally discharged through the exhaust duct 6.
