Spraying technology for automobile parts

Abstract

The invention provides a spraying technology for automobile parts. The spraying technology comprises the following steps of S100, pretreatment on the surfaces of the parts, S200, jig mounting, S300, automatic spraying, S400, nanometer heating leveling, S500, UV curing, S600 appearance inspection and S700, protective film pasting, wherein at S100, the surfaces of the parts are subjected to polishing with fine sand, primary electrostatic dust removal, oil removal and decontamination, and secondary electrostatic dust removal; at S200, the parts are put into corresponding tooling jigs, with the spacing between the parts being 5 cm; at S300, to-be-sprayed surfaces of the parts are sprayed through a spray gun; at S400, the parts are transported to a nanometer heating leveling area, and the nanometer heating leveling area can heat the parts from inside to outside with a heating temperature being 45-55 DEG C and the leveling time being 160-360 s; at S500, the parts are subjected to UV curing by UV curing equipment for 35-45 s; at S600, appearance inspection is performed on the parts; and at S700, the surfaces of the parts are sprayed with static films. Therefore, the appearance of high-gloss parts is met, at the same time the one-time qualified rate of products is raised, the waste of resources is reduced and the effects of energy saving and emission reduction are facilitated.

Description

technical field [0001] The invention relates to the technical field of auto parts production, in particular to a spraying process for auto parts. Background technique [0002] At present, the use of automobiles is constantly increasing, and large and small automobiles can be seen everywhere on the road, and auto parts are the units that constitute the whole of the car and the products that serve the car; Heating pipeline type heating structure, its heating principle is through air conduction, heat dissipation in all directions, and conduction from the surface of the accessories inwards. In the application of spraying of auto parts, the paint is first dried from the surface layer to the inner layer. This heating method It is easy to cause orange peel and light loss defects on the sprayed surface of the accessories. Since the inside of the accessories is dried after the surface layer, and the UV oil is still in the leveling process, it is easy to cause fat edges and sagging de...

Problems solved by technology

[0003] The main purpose of the present invention is to provide a spraying process for auto parts, which overcomes the deficiencies of the prior art, and can effectively solve the problems in the prior art that the parts are prone to fat edges and sagging defects during the spraying process, so that the produced parts Good quality accessories and high pass rate

[0004] Another object of the present invention is to provide a spraying process for auto parts, which can effectively solve the problem of orange peel and loss of light defects on the surface of the parts sprayed by heating during the traditional parts spraying process, so that the surface saturation of the produced parts is high , good gloss
