Abstract

The invention discloses a specialized automobile hub spraying process, which comprises the following steps of: 1) plugging a valve hole of an automobile hub by using a plugging tool, placing the automobile hub on a tray, then positioning the automobile hub on the tray by using the match of a positioning pin and a PCD hole of the automobile hub, finally driving the bottom of the tray to rotate by a power source, and spraying a web plate surface by adopting a spraying manipulator; 2) baking paint on the web plate surface of the automobile hub fixed on the tray; and 3) covering a pressing plate matched with the web plate surface of the automobile hub on the web plate surface, driving the bottom of the tray to rotate by the power source, and spraying an LIP surface by the spraying manipulator so as to finish secondary spraying. The spraying color of the web plate surface is different from that of the LIP surface. The spraying process solves the problem of single hub spraying color, is uniform to spray, does not produce asymmetry or discordance, and has the advantages of simple process, convenient operation and low cost.

Description

technical field

[0001] The invention relates to a special two-color spraying process for automobile wheel hubs. Background technique

[0002] At present, the panel spraying and LIP surface spraying of large-scale mechanized production of automobile wheels on the market are mostly monochrome spraying, with a single color, and there are valve holes on the LIP surface, which may cause uneven spraying due to air pressure problems during spraying, resulting in paint thickness. Uneven, affecting appearance. On November 26, 2008, the State Intellectual Property Office of China disclosed an invention patent called a processing technology for partitioned electroplating and coating wheel hubs and special protective gear. The publication number is 101311324. The invention combines electroplating and spraying processes , the surface treatment of non-pure spraying partitions, and the purpose is not to solve the problem of single color.
