[0037] See also Figure 2 and Figure 3In a feasible embodiment of the present invention, the coating liquid tank 3 is equipped with a circulation pump 31 for circulating the coating liquid. A 15KW heating pipe 21 is installed under the heating water tank 2 to heat the water in the heating water tank 2. Figure 5 , the transmission device is a slide 5. Air supply equipment is also provided on both sides of the coating liquid box 3 for blowing air to quickly dry the forging surface.

[0038] In a feasible implementation manner of the utility model, the air supply device is a floor fan. The bottom of the heating water tank 2 and the coating liquid tank 3 are both equipped with pulleys for easy movement.

[0039] The working process of the utility model is as follows:

[0040] (1) Use the heating pipe 21 below the heating water tank 2 to heat the 200kg water in the water tank to 95℃-100℃

[0041] (2) Workers hang forgings on the coating claws 4 at the starting position of the truss 1, hanging 4 pieces at a time;

[0042] (3) The lifting claw 4 moves the forging to the top of the heating water tank 2 and then sinks it into the water, where it remains for 50 seconds, and the hot water in the water tank is used to heat the forging.

[0043] (4) After 50 seconds, the forging is lifted up by the lifting claw and removed from the hot water. At this time, the surface temperature of the forging is about 80℃-85℃. After rising, it remains still for 10 seconds, and the heat of the forging itself allows the forging to dry naturally.

[0044] (5) After 10 seconds, use the lifting claw 4 to move the forging truss 1 to the position above the coating liquid box 3, sink it into the coating liquid, and hold it for 5 seconds. At this time, the coating liquid circulates through the circulation pump 31 equipped in the box, so that the coating liquid is evenly coated on the surface of the forging.

[0045] (6) After 5 seconds, the forging is separated from the coating liquid by using the lifting claw 4, and after rising, it remains stationary for 20 seconds. At this time, the fans on both sides of the coating liquid box 3 are started to dry the surface of the coating liquid, so that the coating liquid finally forms a uniform coating layer on the surface of the forging.

[0046] (7) After 20 seconds, the forging is returned to the starting position of the truss 1 by the lifting claw 4, and the coated and dried forging is placed in the chute 5 and transferred to the cold forging equipment 6. At this point, the entire coating process is completed.

[0047] Compared with the original coating process, the entire automatic coating line of the utility model occupies an area of ​​about 2.5 square meters, which is small. The labor intensity of workers is greatly reduced. With single-person operation, 4 forgings can be hung at a time. The production efficiency is high, the process steps are few, and a single person produces about 100 pieces per hour. Compared with the original process of 75 pieces per person per hour, the output is increased by 33%. After coating, the forgings are directly transferred to the cold forging equipment through the chute, eliminating the forklift transfer process and saving transfer time.

[0048] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
