After the heating is completed, the part continues to move up and down. At the same time, the annular water-cooling part 106 sprays water on the part from the circumference to quickly cool it to complete the quenching. The cooling waste water generated by quenching passes through the support plate 1 The filter plate 103 on 02 flows into the water tank 101 for collection; after quenching is completed, the fixing frame 205 drives the parts to move to the top below the drying device, and slowly moves downward.
