Description
Technical Field
The invention relates to the field of aluminum decorative plate processing, in particular to a processing method of a metal single-side precise embossing texture.
Background
At present, the commonly used metal embossing process in the market is double-sided embossing which is commonly called bump printing. However, due to technical limitations, the embossing process in the prior art is still a plate pressing method, the processing area is small, continuous production cannot be realized, and the requirement on the output pressure of equipment is high. Such as that disclosed in chinese patent publication No. CN201720352400.8 entitled embossing apparatus for sheet processing.
The metal aluminum plate produced by the plate pressing method has thinner material requirements, and the single-side texture effect cannot be realized due to warping and double-side imprinting in the imprinting process. In addition, most embossing equipment adopts a low-precision laser etching or chemical etching method for manufacturing the roller, so that the embossed texture is thick, and the texture fineness can only reach about 0.2 mm. In view of the above, there is no mature supply of mass-produced precision single-sided metal embossed texture products.
Disclosure of Invention
The invention aims to provide a processing method capable of realizing single-side embossing on a metal aluminum plate.
In order to solve the technical problem, the invention is solved by the following technical scheme:
a processing method of metal single-side precise embossing textures comprises the following steps:
s1, engraving an embossing roll shaft, engraving the roll shaft into the embossing roll shaft through high-precision laser etching, and installing the processed embossing roll shaft in a rolling device, wherein the roll shafts which are mutually rolled in the rolling device comprise an upper roll shaft and a lower roll shaft, the lower roll shaft is a smooth surface, and the upper roll shaft is the embossing roll shaft; wherein the high-precision laser engraving machine is a LASERTEC laser engraving machine.
S2, leveling and cleaning the metal plate;
s3, passivating the metal plate;
s4, single-side embossing of the metal plate, namely putting the metal plate passivated in the step S3 into a rolling device in the step S1 for single-side embossing;
s5, spraying the embossing surface of the metal plate, and coating the surface of the metal plate processed and formed in the step S4 with a coating; by adopting a surface coating method, the surface of the embossed metal plate is coated with a layer of coating with the thickness of 15-30um, so that the physical properties of bending resistance and easy forming can be improved. Wherein the coating adopts pure epoxy powder coating.
And S6, leveling the surface of the metal plate, and putting the metal plate processed and formed in the step S5 into a leveling roller group for rolling and leveling.
The method is further optimized as follows: in step S1, the surface of the embossing roller shaft is processed into the embossing roller shaft with the concave depth of 60-70um and the line diameter width of 0.08-0.12 mm.
The method is further optimized as follows: in step S2, after the metal sheet is leveled, the metal sheet is degreased by an alkaline degreasing solution at 55 to 60 ℃, and then cleaned by RO pure water.
The method is further optimized as follows: in step S3, a weak base or weak acid passivator is uniformly coated on the surface of the metal plate through a coating roller, and a chemical passivation film layer with the thickness of 0.5-1um is formed. The passivation pretreatment film can enable the aluminum plate to be placed in an environment with the temperature of 25 +/-3 ℃ and the relative humidity of below 60 percent, and the corrosion resistance can still reach 7-14 days.
The method is further optimized as follows: the weak base or weak acid passivating agent comprises a silylation agent or a fluorination treatment agent.
The method is further optimized as follows: the coating roller shaft is continuously supplemented with the passivating agent by a circulating spraying process. The weak base/weak acid passivation pretreatment reagent can be recycled, so that a circulating spraying process is adopted, and the circulating spraying process basically belongs to a zero-emission process.
The method is further optimized as follows: the metal plate conveying speed in the step S4 is 1 to 6m/min, and the pressing force of the rolling device is 50T. The embossing roll shaft can form a strong meshing and extruding action with the surface of the metal plate, and the surface of the metal plate with softer hardness can be pressed into embossing textures with the shape corresponding to the embossing roll shaft and the depth of the embossing textures being 40-50 um.
Due to the adoption of the technical scheme, the invention has the remarkable technical effects that:
1. the processing of precise embossing textures on the metal sheet can be realized through 50T small-sized rolling equipment without using an ultra-large rolling machine of more than 200T, and the problem of rapid industrialization is effectively solved.
2. The embossing roller shaft precision laser engraving process is adopted, engraving process simulation operation is realized through a computer, the continuity problem of the seam position is effectively solved, the processing length of the roller shaft can reach 1.2-1.5 m, the processing requirement of parts with conventional sizes can be met, and the problem of continuity production stability which troubles the flat plate embossing process is solved.
3. By adopting the method of rolling first and then coating, the problems of scratch, coating damage and the like in the rolling process due to the processes of spraying first and rolling second can be avoided, partial extremely tiny defects can be covered, and the processing yield can be improved by more than 20-30%.

The aluminum plate 3 is first cleaned, degreased by an alkaline degreasing fluid at 55-60 ℃, and then cleaned by RO pure water. Then, the metal plate is passivated by a coating roll shaft (not shown in figure 1 and positioned before an embossing station) and a circulating spraying process, a silanization agent is uniformly coated on the surface of the metal plate, and a chemical passivation film layer with the thickness of 0.5-3um is formed; then, enabling the aluminum plate with the passivation film to pass through 50T hydraulic embossing equipment with hexagonal lines, and forming lines meshed with an embossing roll shaft on the upper surface of the aluminum plate under the action of continuous and uniform pressure; and then, passing the embossed aluminum plate through a coating roller shaft 4 with staining ink at the speed of 3-6m/min, and baking for 10-15min in an oven at the temperature of 150-.
