Description
Technical Field
The invention relates to the technical field of automobile spraying tools, in particular to a spraying tool for a car body opening cover.
Background
With the requirement of light weight of automobiles, more and more lightweight materials are gradually replacing steel plate materials, and PPE-PA (thermoplastic material) car body covers (such as fuel tank covers) are one of the applications and are widely popular in various major host factories. Because the car body covering cap is an appearance piece, the car body covering cap is used relatively frequently, and a user can perceive the appearance quality of the car body covering cap obviously. Several spray patterns, such as fuel tank caps, are as follows:
1. and (3) coating the finished product on the vehicle door of the body-in-white by welding, and finishing the finished product together with the whole vehicle body. The scheme is subjected to a complete coating process, which means that electrophoresis baking is required, and the baking temperature is generally 180 ℃ and 200 ℃. The main problems to be overcome are: the heat resistance of the material of the fuel tank opening cover is basically close to the thermal deformation temperature limit of most materials of PPO/PA, and the material has large deformation after being heated and is difficult to control.
2. And (3) spraying paint on the coated upper piece on line along with the whole vehicle body without electrophoresis and electrophoresis baking and on the middle coating line. Compared with the scheme 1, the electrophoresis baking with the highest baking temperature is skipped, and the piece is still baked at two high temperatures before the middle coating, namely the middle coating baking (the temperature is 170-180 ℃) and the finish baking (the temperature is 90-120 ℃); the temperature of the middle coating baking is relatively high, but the thermal deformation temperature of the material is not reached, in the heating process, due to the expansion and contraction characteristics of the material, the material expands when heated, and after the room temperature is recovered, the material has relatively stable size change, through early-stage process pre-adjustment, the material can easily meet the requirement of appearance matching, and the material is painted with the vehicle body together, almost has no color difference with the vehicle body, and is favored by vast host factories. However, due to the on-line spraying scheme for coating the upper part, the baking temperature is still high, in the baking process of the middle coating (the middle coating primer is also called as a secondary primer, which is a construction process), due to the difference of the expansion coefficients of the plastic fuel tank cap and the metal tool, the fuel tank cap is easy to be mutually constrained with the existing tool to generate a relative acting force in the high-temperature expansion process, the material softened at the high temperature is easy to deform, and when the temperature is restored to the room temperature, the permanent deformation is generated, so that the appearance matching problem is caused, and the rejection rate is high.
3. And (4) off-line spraying, namely, after the individual oil tank caps are painted at a paint spraying supplier, the individual oil tank caps are delivered to a host factory to be assembled into a whole vehicle. Compared with the schemes 1 and 2, the scheme has the advantages that the deformation of the material is very small because the scheme only needs to be baked by a finish (90-120 ℃); but because the oil tank port cover is independently painted, the problem that the cost is high, the color difference between the oil tank port cover and the color of the automobile body is easy to exist, and the rejection rate is relatively high.
