The cold air in the cold air cavity 14 and a part of the hot air in the hot air cavity 15 enter the mixed air outlet pipe 12 from the first air hole 20, and mixed to form cooling air with proper temperature, and then the cooling air is conveyed into the cooling bin 1 by the air blowing fan 2, cooling the heat-treated rivet, discharging redundant hot air in the hot air cavity 15 from the multi-residual heat air discharge pipe 11 through the second air hole 21, the temperature of the cooling air entering the cooling bin 1 is monitored by the first temperature sensor 5, the temperature of the hot air entering the hot air cavity 15 is monitored by the third temperature sensor 7, when the temperature of the cooling air or the temperature of the hot air deviates from the preset temperature value, the proportion of the cold air and the hot air entering the mixed air outlet pipe 12 is adjusted by the cold air and hot air proportion adjusting mechanism, so that the temperature of the cooling air entering the cooling bin 1 is maintained in a proper range, and the specific adjusting steps of the ratio of the cold air to the hot air are as follows: when the temperature monitored by the first temperature sensor 5 or the third temperature sensor 7 is lower than a preset temperature value, the motor 38 of the translation mechanism drives the rotating shaft 37 and the first gear 39 to rotate, the first gear 39 drives the second gear 40 and the threaded sleeve 36 to rotate, the threaded sleeve 36 drives the screw 35 and the baffle 10 to move towards the left direction in fig. 2, so that the hot air entering the mixed air outlet pipe 12 from the hot air cavity 15 is gradually increased, the hot air discharged into the redundant hot air discharge pipe 11 from the hot air cavity 15 is gradually decreased, and the cold air entering the mixed air outlet pipe 12 from the cold air cavity 14 is gradually decreased, so that the proportion of the hot air is increased, the proportion of the cold air is decreased, and the temperature of the cooling air entering the cooling bin 1 is increased; when the temperature monitored by the first temperature sensor 5 or the third temperature sensor 7 is higher than a preset temperature value, the translation mechanism drives the baffle 10 to move rightwards, so that the hot air entering the mixed air-out pipe 12 from the hot air cavity 15 is gradually reduced, the hot air discharged into the redundant hot air discharge pipe 11 from the hot air cavity 15 is gradually increased, and the cold air entering the mixed air-out pipe 12 from the cold air cavity 14 is gradually increased, so that the proportion of the hot air is reduced, the proportion of the cold air is increased, the temperature of the cooling air entering the cooling bin 1 is further reduced, and the temperature of the cooling air entering the cooling bin 1 is always maintained in a proper range. When the cold and hot air control mechanism of the constant temperature system for heat treatment is started, the temperature of the hot air entering the hot air cavity 15 from the hot air inlet 17 is still low, so that the cooling air entering the cooling bin 1 needs to be preheated by the heating wire 4, the temperature of the cooling air entering the cooling bin 1 after the start reaches the required temperature as soon as possible, and when the temperature reaches the required value, the heating wire 4 is closed.
