Abstract

The invention belongs to the field of automobile production, and particularly discloses a spraying method for an automobile spare part. The method comprises the following steps of oil removing, rust removing, drying, dust removing, spraying, drying and curing, checking and warehousing; in the spraying step, spraying equipment is adopted for finishing rough spraying on the inner wall of a workpiece and fine spraying on the outer wall of the workpiece at a time, during spraying, the workpiece and a spraying head are kept to relatively move at the constant speed, and a coating is evenly distributed and is full. The scheme is adopted for spraying the workpiece, spraying can be conducted on the inner wall and the outer wall of the workpiece at a time, the spraying efficiency is higher, the production cost is saved, and the production period is shortened; and according to the scheme, the workpiece outer wall coating uniformity can be improved, the surface quality of the workpiece obtained after machining is high, the coating is smooth, uniform and high in brightness, and the qualification rate of the workpiece is increased.

Description

technical field [0001] The invention belongs to the field of automobile production, and in particular relates to a spraying process for accessories. Background technique [0002] Many auto parts need to be sprayed during processing, some auto parts only need to be sprayed on the outer wall, and some auto parts need to be sprayed on the inner and outer walls, such as metal auto parts, for this kind of car that needs to be sprayed on the inner and outer walls For accessories, people have higher requirements on the uniformity of spraying on the outer wall of auto parts, but only rough spraying on the inner wall of the car to achieve the purpose of preventing the workpiece from rusting. [0003] The current spraying method used for auto parts is to use a spraying equipment to spray the inner wall of the auto parts, and then send the workpiece to the next spraying equipment to spray the outer wall of the workpiece after completing the spraying and drying of the inner wall. The e...
