Open the protective door by operating the handle, hang the placement hole plate on the support hanging rod through the support buckle rod on the connecting vertical rod and close the protective door. Control the output end of the driving motor to drive the synchronous rotating rod to rotate. The synchronous rotating rod drives the two rotating shaft rods located in the upper position to rotate synchronously and reversely through two active steering gears and two passive steering gears. Then, drive the mutually approaching ends of the lifting chains on the left and right sides of the inner cavity of the equipment box to move upward synchronously through the lifting sprockets. Thus, the flange on the placement hole plate connected to the support hanging rod moves upward to correspond to the position of the heating plate. Turn on the heating plate to heat the flange. After the flange is heated, introduce the liquid for quenching into the bottom of the inner cavity of the equipment box through the liquid inlet valve pipe. Control the output end of the driving motor to rotate in the reverse direction to drive the flange to be quenched on the placement hole plate to move downward into the liquid at the bottom of the inner cavity of the equipment box for quenching operation. After the flange is quenched, control the output end of the driving motor to rotate to drive the flange on the placement hole plate to move upward to align with the placement opening. At this time, the protective door can be opened to take out the flange through the placement hole plate. The above operations are simple and practical, with a reasonable and compact structure, reducing the number of manual transfers of the flange by the staff and avoiding the staff's contact with the high-temperature flange, improving the work efficiency and safety of the staff.

[0017] 2. The quenching device for flange processing, by setting up a protective baffle. When the placement hole plate drives the flange to move downward to the bottom of the inner cavity of the placement hole plate for quenching, the protective baffle moves downward synchronously with the placement hole plate and forms a shield for the top of the placement hole plate to prevent the water vapor generated during quenching from contacting the heating plate and causing damage, improving the service life of the equipment.
