Description

Technical Field

[0001] This utility model relates to a shell processing equipment, specifically a high-temperature resistant axial flow fan shell processing equipment, belonging to the field of axial flow fan component processing technology. Background Technology

[0002] Axial flow fans have a wide range of applications. They are airflows that run in the same direction as the fan blades' axis, such as electric fans and air conditioner outdoor unit fans. They are called "axial flow" fans because the gas flows parallel to the fan's axis. Axial flow fans are usually used in applications where high flow rate and low pressure are required. Axial flow fans are fixed in position and move air. To prevent the fan casing from rusting, anti-rust paint is sprayed on the surface of the parts to isolate the metal surface from the external moisture environment.

[0003] Chinese Patent Publication No. CN217450837U discloses a primer spraying device for plastic parts, which includes a housing, a suction fan, a blower, and a heating assembly. The housing includes a processing box and support plates fixedly installed on both sides of the lower surface of the processing box. The suction fan is embedded in one side surface of the processing box. The blower is embedded in the other side surface of the processing box. The heating assembly is fixedly installed on the other side surface of the processing box and located outside the blower. The heating assembly includes a heating frame, a plurality of electric heating tubes symmetrically fixedly installed on the inner side of the heating frame and facing away from the blower, and an air inlet penetrating through one side of the heating frame and facing away from the other side surface of the processing box.

[0004] However, the inventor of the above-mentioned device believes that there are certain defects. During the process of rotating and spraying paint on the fan housing, the device lacks a fixing component to fix the workpiece, which makes it easy to deviate during rotation, affecting the spraying effect. In addition, the external clamping and fixing method leads to the phenomenon that the clamping part is not sprayed in place. Therefore, this utility model provides a high-temperature resistant axial flow fan housing processing equipment. Utility Model Content
