The mounting frame 210 is a rectangular frame, and the mounting frame 210 is welded on the quenching tank 100. The plurality of sprockets 230 are rotatably mounted on the mounting frame 210. Specifically, a sprocket 230 is rotatably mounted on each of the four corners of the mounting frame 210. The chain 220 is sleeved on all the sprockets 230. Under the support of all the sprockets 230, the chain 220 also has a rectangular structure, and the lower side of the chain 220 spans across both ends of the length direction of the quenching tank 100. All the hooks 300 are arranged in sequence on the lower side of the chain 220, the upper end of the hook 300 is hung on the lower side of the chain 220, the lower end is connected to the parts to be quenched, and the parts can be immersed in the quenching tank 100. Under the drive of the chain 220, all the hooks 300 move from one end of the quenching tank 100 to the other end.

[0034] By adopting the above technical solution, when the parts are heated to a certain temperature, the staff can use the hook 300 to hang the parts on the chain 220 and immerse the parts in the quenching pool 100; and the driving motor 240 can drive the chain 220 to move at a preset speed through the sprocket 230, so as to drive the parts from one end of the quenching pool 100 to the other end through the hook 300; when the parts move to the end of the quenching pool 100, external equipment (such as a manipulator, an electric hoist, etc.) is used to act on the hook 300, and the parts can be removed from the chain 220 through the hook 300; because the chain 220 is continuously running, the staff can continuously and uninterruptedly hang the heated parts on the chain 220, so that multiple parts can be immersed in the quenching pool 100 for cooling. This design can not only improve the quenching cooling efficiency, but also improve the quenching cooling quality.

[0035] In this embodiment, the quenching and cooling device also includes a transfer mechanism, which can transfer the heated parts from the heating device to the chain 220. The transfer mechanism includes an electric slide rail 410, a hanging movable frame 420 and an electric hoist 430. The electric slide rail 410 is provided in two, which are arranged on both sides of the quenching pool 100 respectively. Two sliders 421 are installed on the bottom side of the hanging movable frame 420, and the two sliders 421 are slidably installed on the two electric slide rails 410 respectively.

[0036] By adopting the above-mentioned technical solution, before the parts are heated, they are first connected to the lower end of the hook 300; when the parts are heated to a certain temperature, the upper end of the hook 300 is connected by the hook 432 to take out the parts; then the hanging movable frame 420 is moved to one end of the quenching pool 100 by the electric slide rail 410; then the lifting rope 431 is lowered by the electric hoist 430 so that the upper end of the hook 300 can contact the lower side of the chain 220; finally, the staff can easily transfer the hook 300 to the lower side of the chain 220, so that the parts are immersed in the quenching pool 100.

[0037] It should be noted that the electric slide rail 410 and the electric hoist 430 are both electric control mechanisms, and their principles and structures are all prior art, which will not be described in detail in this embodiment. The staff can control the operation of the electric slide rail 410 and the electric hoist 430 through an external remote control panel.
