AI Technical Summary
Existing cooling devices cannot be adapted to different types of hollow shafts, resulting in uneven spraying, especially insufficient cooling at both ends of long shafts, making it impossible to achieve uniform cooling of the inner and outer surfaces.
A cooling device was designed, which includes a spray frame, an inner spray pipe, and various adjustable components. Through the cooperation of an angle ring and a sliding plate, the nozzle angle and position can be flexibly adjusted. Combined with the threaded shaft driving the spray pipe to slide, it ensures uniform spraying of the inner and outer surfaces.
It achieves uniform spray cooling of the inner and outer surfaces of hollow shafts, adapts to hollow shafts of different shapes and lengths, ensures consistent cooling rates at both ends of long shafts, and improves cooling efficiency.
