Description

Technical Field

[0001] The utility model relates to the technical field of painting equipment for cast iron parts, in particular to a painting device for cast iron parts. Background Art

[0002] Cast iron parts are a kind of metal parts, which are mainly cast by casting water. They have the properties of wear resistance, corrosion resistance, thermal shock resistance, fatigue and shock absorption. They are widely used in the machinery industry. In order to improve the use of cast iron parts, a painting device is generally used to paint the cast iron parts. The painting device is mainly divided into two types, one is a smearing type and the other is a spraying type. The smearing type, as the name implies, is to smear the paint on the cast iron parts to achieve the painting of the cast iron parts, while the spraying type is to spray the paint on the cast iron parts by spraying to achieve the painting of the cast iron parts. The painting devices in the prior art are as follows:

[0003] For example, the patent publication number CN220371357U discloses a paint spraying device. The utility model includes a steel seat, a base and a support rod. A gantry is fixedly installed on the top of the steel seat, a paint spray gun is installed on the top of the gantry, and a base is fixedly connected to the right side of the steel seat. The upper part of the base has a groove inside, and the groove has two shear plates. The right ends of the bottom of the two shear plates are rotatably connected to the inner walls on both sides of the groove respectively, and the left ends of the bottom of the shear plates are rotatably connected to the sliding rod, and the sliding rod is rotatably connected to the left inner wall of the groove. A fixed block is fixedly installed on the outer wall of the sliding rod, and an electric lifting rod is fixedly installed on the outer wall of the fixed block. The utility model can make the processed objects rise and fall and rotate at a uniform speed during the painting process, so as to improve work efficiency, control coating thickness, ensure safe production, improve paint quality, reduce equipment loss and other optimization effects during the spraying process of the processed objects, while reducing the manual burden and safety risks of the staff;

[0004] Although the utility model can spray cast iron parts, there are still the following problems:

[0005] 1. First, when the shape of the cast iron part is tubular, although the equipment can spray the surface of the cast iron part, when the inner wall of the filling needs to be sprayed, the spray gun in the equipment cannot be extended to the inner wall of the pipe, resulting in the inside of the pipe cannot be sprayed, so that subsequent personnel are required to spray the inner wall of the pipe, which will bring unnecessary trouble to the personnel and reduce the spraying efficiency of the pipe cast iron parts.

[0006] 2. Secondly, in the utility model, one end of the pipe needs to be placed on a rotating placement disk. When spraying the pipe, not only the outer surface and the inside of the pipe need to be sprayed, but also the surfaces at both ends of the pipe need to be sprayed to achieve the anti-rust effect. If one end of the pipe is attached to the rotating placement disk, the surface cannot be sprayed smoothly, and personnel will need to turn the pipe over to spray the other side, which will greatly increase the labor of personnel and reduce the efficiency of pipe spraying.
