[0028] The working principle of a hot forging die cooling device provided by the utility model is as follows: when working, firstly, the cooling table 1 and the bracket 2 and other mechanisms are stably placed in the horizontal working area. After being placed stably, the personnel realize the operation of the front and rear two motors 7 by controlling the switch group 19. The rotation of the output shaft of the motor 27 drives the transmission roller 6 adjacent to the horizontal side to rotate, and then drives the driving wheel 8 adjacent to the horizontal side to rotate. Under the transmission action of the corresponding transmission belt, the driven wheel 9 adjacent to the longitudinal side is driven to rotate. The rotation of the driven wheel 9 drives the transmission roller 6 adjacent to the horizontal side to rotate. The personnel place the hot forging die to be cooled in the rear The hot forging die to be cooled is transferred to the cooling working area by the upper end between the three conveyor rollers 6 at the end, and the hot forging die to be cooled is stationary at the upper end of the two support plates 10. Then, the personnel realize the operation of the motor 31 by controlling the switch group 19.

After the hot forging die is cooled, the staff controls the switch group 19 to realize the reverse operation of the motor 1 31, so that the sliding frame 5 moves up, thereby driving the evenly distributed nozzles and the baffle to move up. When the nozzle returns to the initial position, the staff controls the switch group 19 to turn off the motor 1 31 and realize the operation of the motor 3 12. When the motor 3 12 runs, the output shaft of the motor 3 12 rotates to drive the conveyor roller 2 11 to rotate, thereby conveying the cooled hot forging die to the upper end of the three conveyor rollers 1 6 at the front end, and then conveying the conveyor roller 1 6 at the front end to the next working area.
