[0033] Working principle: When the workpiece needs to be tempered, the material table 6 is lifted to the top of the water cooling tank 2 and matched with the first stroke switch 12 through the lifting device 5, and then the workpiece is placed on the material table 6 through an external material cart, and then the material table 6 is lifted to the second stroke switch 13 through the lifting device 5.

[0034] When the workpiece needs water cooling, open the lifting sealing door 3, start the push chain device 7 to drive the high-temperature push head 8 to push the tempered workpiece to the material table 6. After the workpiece is in place, the lifting device 5 will first drive the material table 6 to rise to the second stroke switch 13 position, and the push chain device 7 will pull back the high-temperature push head 8. Then the lifting device 5 drives the material table 6 to quickly descend into the water cooling tank 2 to achieve rapid cooling of the workpiece, and the position is set by the lower limit device 11. Start the stirring device 10 and the cooling device 9, and stir with the stirring devices 10 on both sides. The coolant is quickly cooled to the workpiece through the guide device 15 to ensure the uniformity of the cooling of the workpiece. After the water cooling is completed, the lifting device 5 drives the material table 6 and the workpiece to rise to the first stroke switch 12 position, and the workpiece after water cooling is pulled out by the material cart.
