[0035] Working principle:

[0036] First, start the lifting drive motor 21, wind the lifting rope 24, and pull the lifting and placing component 5 to lift it. After placing the parts that need to be tempered on the top of the storage plate 53, control the lifting drive motor 21 to reverse and make the lifting and placing component 5 slowly descend, and make the process smoother by slowing down the fixing component 22 and the sliding block 23. Then turn on the heating to evenly distribute the heating outer cylinder 52 to make the tempering effect of the parts uniform. After the heating is completed, control the lifting drive motor 21 again to make the lifting rope 24 pull the lifting and placing component 5. After the lifting and placing component 5 is lifted, the heating outer cylinder 52 is connected to the ventilation slot 43. Turn on the cooling fan 1 to transfer the cooling airflow to the parts through the ventilation slot 43 for cooling. After cooling, take it out.
