AI Technical Summary
Existing sponge drilling equipment has low heat dissipation efficiency of the drill bit, which causes sponge deformation and affects processing accuracy. It also requires frequent shutdowns for heat dissipation and tool sharpening, which affects production efficiency.
A cooler is integrated into the air-cooled pipe. The vortex tube cooler generates a low-temperature airflow to cool the drilling tool assembly. The airflow is blown onto the drilling tool assembly through the air outlet on the air-cooled pipe, resulting in an even lower cooling airflow temperature and improved cooling effect.
It effectively avoids frequent shutdowns for heat dissipation and tool sharpening, improves processing efficiency and product accuracy, reduces downtime frequency, and ensures that the drilling tool set operates at a lower temperature.
