The fan 203 generates airflow to quickly air dry the metal parts in the bottom box 401. Then, the servo motor 4031 is started. The servo motor 4031 drives the second rotating rod 402 to rotate, thereby driving the bottom box 401 and the top box 4011 to rotate. During the rotation of the bottom box 401, the water stains thrown away are blocked by the rectangular frame 202 and fall into the water tank 103, and the air drying of the metal parts is further accelerated by the rotation.

[0036] The lifting assembly 300 includes a first rotating rod 301, which is rotatably connected to one side of the inside of the base 101, and a rotating handle 302 is fixedly connected to one end of the first rotating rod 301. The surface of the first rotating rod 301 is rotatably connected to a driving gear 303, and the surface of the driving gear 303 is meshed with a driven gear 304. A screw 305 is fixedly connected above the driven gear 304, and a first connecting block 306 is threadedly connected to the surface of the screw 305. When in use, the rotating handle 302 drives the first rotating rod 301 to rotate, so that the driving gear 303 drives the meshed driven gear 304 to rotate, thereby rotating the screw 305.

[0040] Furthermore, a top box 4011 is detachably connected to the top of the bottom box 401, and water-permeable grooves 4012 are provided on the bottom box 401 and the top box 4011. The metal parts are clamped and fixed by the bottom box 401 and the top box 4011, and the cooling liquid can enter through the water-permeable grooves 4012 to quickly cool the metal parts.

[0041] Furthermore, the other side of the bottom box 401 is rotatably connected to a second connecting block 4021 via a second rotating rod 402, and a through hole is provided on the second connecting block 4021. When the second rotating rod 402 on one side of the bottom box 401 drives it to rotate, the second rotating rod 402 on the second connecting block 4021 rotates at the same time, making the rotation of the bottom box 401 smoother.

[0044] Then, the servo motor 4031 is started, and the servo motor 4031 drives the second rotating rod 402 to rotate, and the second rotating rod 402 drives the bottom box 401 to rotate, and the bottom box 401 rotates to turn over the internal metal parts, and at the same time, the fluidity of the coolant in the water tank 103 is increased, so that the cooling effect of the metal parts is better;

[0045] Finally, turn off the servo motor 4031, rotate the handle 302 in the opposite direction to drive the screw 305 to rotate in the opposite direction, so that the fixing component 400 moves up to the rectangular frame 202, and start the fan 203. The fan 203 generates an airflow to quickly dry the metal parts in the bottom box 401, and then start the servo motor 4031. The servo motor 4031 drives the second rotating rod 402 to rotate, thereby driving the bottom box 401 and the top box 4011 to rotate. The water stains thrown away during the rotation of the bottom box 401 are blocked by the rectangular frame 202 and fall into the water tank 103, and the drying of the metal parts is further accelerated by the rotation.

[0046] It is worth noting that the entire device is controlled by a controller. Since the controller is a commonly used device and belongs to the existing mature technology, its electrical connection relationship and specific circuit structure will not be described in detail here.
