[0016] In addition, if the terms "first", "second" are only used for description purposes, and cannot be understood as indicating or suggesting relative importance or implicitly indicating the number of technical features. Therefore, the "first", "second" features can be explicitly or implicitly included one or more features, and in the description of the utility model, the meaning of "several", "several" is two or more than two, unless otherwise explicitly specified.

[0017] Referring to Figure 1 And Figure 2 Further illustrate the utility model.

[0018] A tempering furnace cooling device, comprising a bracket mounted on the side of the furnace body 1, the bracket is provided with an air blower 2, the air outlet of the air blower 2 is connected with a first air pipe 3, the first air pipe 3 is connected with a hose 4, the hose 4 is connected with a second air pipe 5, and the second air pipe 5 is located above the furnace body 1 and communicates with the inside of the furnace body 1.

[0019] As 1 and Figure 2 When the furnace body 1 needs to be cooled, the air blower 2 is started, and the normal temperature air in the furnace body 1 is blown into the outside through the first air pipe 3, the hose 4 and the second air pipe 5, so that the inside of the furnace body 1 is rapidly cooled, the cooling efficiency is improved, and the time cost is reduced.

[0020] Specifically, the gas is blown inward from the top of the furnace body 1, which can more effectively exchange heat with the hot air at the top of the inner cavity of the furnace body 1, so as to realize rapid cooling.

[0021] Specifically, a temperature sensor such as a thermocouple is arranged in the furnace body 1, and a controller or a computer device outside the furnace body 1 is connected to the thermocouple and the air blower 2, so that the air blower 2 can be automatically stopped when the temperature in the furnace body 1 decreases to a required temperature, thereby avoiding excessive temperature decrease.

[0022] Specifically, the hose 4 is elastic and can expand and shrink, so that the air pressure in the hose can be automatically adjusted when the air blower 2 blows air, and the vibration of the air blower 2 can be reduced when the air blower 2 operates, thereby ensuring the sealing connection between the second air pipe 5 and the furnace body 1.

[0023] As shown in Figure 1 , in the preferred embodiment, the second air pipe 5 is located at the center of the length direction of the furnace body 1, i.e. the center of the width direction of the furnace body 1, so that the temperature decrease is more uniform.

[0024] As shown in Figure 1 , in the preferred embodiment, the first air pipe 3 is provided with an adjusting valve 6, and the air volume entering the furnace body 1 can be controlled by the adjusting valve 6, so as to control the temperature decrease speed.

[0025] Specifically, the adjusting valve 6 can be an electric control valve, which is automatically controlled by a controller.

[0026] Specifically, the first air pipe 3 or the second air pipe 5 is provided with an air volume sensor for detecting the air volume entering the furnace body 1.

[0027] As shown in Figure 1 , in the preferred embodiment, the second air pipe 5 is provided with an air outlet pipe 7, and the air outlet pipe 7 is provided with an air valve 8 at the pipe opening, so that when the air blower 2 is not used for temperature decrease, the air valve 8 can be opened to automatically discharge the hot air in the furnace body 1 through the second air pipe 5 and the air outlet pipe 7, thereby finely adjusting the temperature in the furnace body 1 and ensuring the stability of the temperature in the furnace body 1.

[0028] Specifically, the inner diameter of the air outlet pipe 7 is smaller than the inner diameter of the second air pipe 5.

[0029] As shown in Figure 1 , in the preferred embodiment, the hose 4 is horizontally arranged.

[0030] As shown in Figure 1 , in the preferred embodiment, the two ends of the hose 4 are respectively connected to the first air pipe 3 and the second air pipe 5 through flanges 9.

[0031] As shown in Figure 1As shown, preferably in the present example, the temperature reducing device is provided with several, and is concentrated in the middle position of the length direction of the furnace body 1, away from the inlet and outlet of the furnace body 1, and a part of the external air will also enter the inlet and outlet of the furnace body 1, so the temperature of the inlet and outlet of the furnace body 1 is lower than that of the middle region of the furnace, and the setting away from the inlet and outlet can more effectively reduce the temperature of the furnace, and ensure the uniformity of the temperature reduction.
