The working principle of the invention is that the cooling liquid tank 2 is internally used for storing cooling liquid, the water pump 201 pumps the cooling liquid into the fixed pipe 203 through the first connecting pipe 202, the stamping of the previous material is switched to the stamping gap of the next material, the telescopic spraying component is controlled to start, the telescopic spraying component sprays the cooling liquid pumped into the fixed pipe 203 by the water pump 201 after atomizing, and sprays the cooling liquid to the upper die 102 and the lower die 101 at the same time, so that the cooling liquid is uniformly sprayed to the surfaces of the upper die 102 and the lower die 101 after atomizing, heat is recovered through sprayed cold area liquid, thereby being beneficial to rapidly and uniformly cooling the surfaces of the upper die 102 and the lower die 101, and avoiding the condition that the use is influenced due to overhigh temperature of the dies;
When the telescopic spraying assembly atomizes and sprays the cold area liquid, the atomized cold area is driven to diffuse to the periphery through the driving action of the airflow driving assembly, so that the atomized cold area is uniformly distributed on the surfaces of the upper die 102 and the lower die 101, and the flow and evaporation action of the atomized cooling liquid can be accelerated through the action of the airflow, so that the cooling effect of the cooling liquid on the die is improved, and the cooling efficiency is improved.
The foregoing has shown and described the basic principles, principal features and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, and that the above embodiments and descriptions are merely illustrative of the principles of the present invention, and various changes and modifications may be made therein without departing from the spirit and scope of the invention, which is defined by the appended claims.
