[0003] Imitation copper brushed aluminum sheets can be used as exterior and interior wall decoration materials and indoor ceilings for new buildings and renovation of old houses. They are particularly suitable for some large public buildings with high population density and high requirements for fire resistance, such as conference centers, exhibition halls, gymnasiums, theaters, etc. At the same time, the installation and construction of imitation copper brushed aluminum sheets are convenient and quick. The aluminum sheets are formed in the factory and do not need to be cut at the construction site. They can be fixed on the frame.

[0004] In order to increase the aesthetics of the imitation copper-aluminum plate, etching is generally used to perform wire drawing on the imitation copper-aluminum plate. However, existing technologies, such as using a left-right swing etching machine, cause more severe side etching and cannot evenly etch the imitation copper-aluminum plate at one time. Summary of the Invention

[0005] In view of this, the present invention provides a method for processing an imitation copper-aluminum plate, which can solve the problem that the imitation copper-aluminum plate cannot be uniformly etched in one go.

[0006] The present invention is achieved in that:

[0007] The present invention provides a method for processing an imitation copper aluminum plate, which comprises the following steps:

[0008] S01: smelting aluminum alloy ingot;

[0009] S02: performing homogenization heat treatment on the aluminum alloy ingot;

[0010] S03: hot rolling the aluminum alloy ingot to obtain an aluminum alloy rolled plate;

[0011] S04: cold rolling the aluminum alloy rolled plate;

[0012] S05: performing annealing treatment on the aluminum alloy rolled plate;

[0013] S06: cold rolling the aluminum alloy rolled plate again;

[0014] S07: Using a positioner to calibrate the aluminum alloy rolled plate to a required size;

[0015] S08: using a cutting machine to cut the aluminum alloy rolled plate along the line calibrated by the positioner;

[0016] S09: spraying a copper-like fluorocarbon paint on the surface of the aluminum alloy rolled plate using an electrostatic sprayer to form a copper-like fluorocarbon paint coating;

[0017] S10: drying and curing the imitation copper-colored fluorocarbon paint coating to obtain an imitation copper-colored aluminum plate;

[0018] S11: using a wind-assisted etching device to perform wire drawing processing on the imitation copper aluminum plate.

[0019] The technical effects of the processing method of the imitation copper aluminum plate provided by the present invention are as follows: by using an electrostatic sprayer to spray the imitation copper-colored fluorocarbon paint, the color difference of a single imitation copper aluminum plate is small, and the plate has strong resistance to fading, blooming, corrosion, ultraviolet radiation, and cracking.

[0020] On the basis of the above technical solution, a method for processing an imitation copper aluminum plate of the present invention can also be improved as follows:

[0021] Wherein, the wind-assisted etching device in step S11 includes a clamping mechanism, an etching mechanism, an etching liquid tray and a blowing mechanism, the clamping mechanism is used to clamp the imitation copper-aluminum plate downward, the etching mechanism is located directly below the clamping mechanism, the blowing mechanism is located below the side of the etching mechanism, the wind direction of the blowing mechanism is toward the surface of the imitation copper-aluminum plate clamped by the clamping mechanism, the etching liquid tray is located directly below the etching mechanism, and the etching liquid tray contains etching liquid;

[0022] The etching mechanism includes a wire frame, an etching line and a lifting rod. The wire frame is a square frame. The area of ​​the wire frame is larger than the area of ​​the clamping mechanism. The etching line arranged according to the drawing pattern is passed through the wire frame. The lifting rod is fixed on the side of the wire frame and is used to lift the wire frame to the etching liquid tray to immerse the etching line and enable the etching line to adhere to the surface of the imitation copper aluminum plate. The etching line can be immersed in the etching liquid.

[0023] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: by using a wind-assisted etching device, the wind blowing mechanism blows the etching line onto the imitation copper-aluminum plate, so that the etching liquid on the etching line is evenly covered on the etching part, and the imitation copper-aluminum plate can be accurately etched, ensuring that the same imitation copper-aluminum plate can be evenly etched at one time, avoiding the accumulation of etching solution on the imitation copper-aluminum plate.

[0024] Furthermore, if the etching lines need to form complex etching wire drawing patterns, the etching lines are connected by acid-resistant non-stick materials, such as polytetrafluoroethylene;

[0025] Optionally, the clamping mechanism has a flip axis, which is convenient for flipping and removing the imitation copper-aluminum plate after etching is completed. The clamping mechanism is mounted above the etching mechanism through a bracket; the clamping mechanism has clamping arms, and the distance between the clamping arms is adjusted by a spring mechanism to clamp imitation copper-aluminum plates of different sizes with quartz; the wire frame is fixed to the lifting rod through the step bracket, and the step bracket has a stepped structure, which is used to avoid the frame of the etching liquid tray and immerse the etching mechanism in the etching liquid of the etching liquid tray.

[0026] Furthermore, the etching wire is a cord twisted from glass fiber material, and the surface of the etching wire has a scale structure.

[0027] The beneficial effect of adopting the above-mentioned improvement scheme is: by using etching lines with fine scales on the surface, the etching lines can be fully immersed in the etching liquid without accumulation, and the imitation copper aluminum plate can be accurately etched to avoid uneven etching.

[0028] Optionally, the etching wire is twisted into a wire using asbestos material.

[0029] Furthermore, the hair dryer structure has a plurality of air outlet heads in a uniform array, and the air outlet heads are connected to a hair dryer via an air duct.

[0030] The beneficial effect of adopting the above-mentioned improvement scheme is that by using a blower mechanism with multiple air outlets, the wind can be blown out evenly and the present invention can still be in a usable state when one of the air outlets fails and leaks air, thereby improving stability.

[0031] Furthermore, the angle between the blowing direction of the air outlet and the clamping mechanism is 20°~45°, and the air blowing mechanism is symmetrically arranged on both sides of the clamping mechanism.

[0032] Furthermore, the blower of the blower mechanism blows inert gas, and the wind speed of the blower is controlled between 0.2 and 0.9 m / s.

[0033] After step S07, the dimensions need to be reviewed. The review method is as follows:

[0034] Step 1: Check whether the aluminum alloy rolled plate after cutting is consistent with the required size. If the size is consistent, proceed to step S08; if the size is not consistent, proceed to the next step;

[0035] Step 2: Adjust the locator so that the calibrated line is closer to the required size, and then proceed to the first step;

[0036] The error between the cut aluminum alloy rolled plate and the required size is less than 1.0 mm.

[0037] The aluminum alloy ingot comprises Al, Mg, Fe and Si, wherein Al is 4.8-6.5wt.%, Mg is 0.5-0.95wt.%, Fe is 0.1-0.8wt.%, Si is 0.06-0.2wt.%, and the content of other trace elements is controlled at 0.1wt.% or less.

[0038] Among them, after the step S11, the imitation copper-aluminum plate is cut according to the position of the design drawing using a corner punching machine, and after cutting, the imitation copper-aluminum plate is bent according to the design.

[0039] In the step S09, the entire process of "spraying the imitation copper-colored fluorocarbon paint with an electrostatic sprayer" requires spraying the imitation copper-colored fluorocarbon paint at least three times.

[0040] Compared with the prior art, the beneficial effects of the method for processing imitation copper aluminum plates provided by the present invention are: by using a wind-assisted etching device, a blower mechanism blows the etching line onto the imitation copper aluminum plate, allowing the etching liquid on the etching line to evenly cover the etching part, and accurately etching the imitation copper aluminum plate, ensuring that the same imitation copper aluminum plate can be evenly etched at one time, avoiding the accumulation of etching solution on the imitation copper aluminum plate; by using an electrostatic sprayer to spray imitation copper-colored fluorocarbon paint, the color difference of a single imitation copper aluminum plate is small, and the plate has strong resistance to fading, frosting, corrosion, ultraviolet radiation, and cracking; by using a blower mechanism with multiple air outlets, the wind can be blown out evenly and the present invention can still be in a usable state when one of the air outlets fails and leaks air, thereby improving stability.

[0055] like Figure 1 FIG. 1 is a first embodiment of a method for processing an imitation copper aluminum plate provided by the present invention. In this embodiment, the method comprises the following steps:

[0056] S01: smelting aluminum alloy ingot;

[0057] S02: homogenizing heat treatment of the aluminum alloy ingot;

[0058] S03: hot rolling the aluminum alloy ingot to obtain an aluminum alloy rolled plate;

[0059] S04: cold rolling the aluminum alloy rolled plate;

[0060] S05: annealing the aluminum alloy rolled plate;

[0061] S06: cold rolling the aluminum alloy rolled plate again;

[0062] S07: Use the positioner to calibrate the aluminum alloy rolled plate to the required size;

[0063] S08: Use a cutting machine to cut the aluminum alloy rolled plate along the line marked by the locator;

[0064] S09: Use an electrostatic sprayer to spray the imitation copper-colored fluorocarbon paint on the surface of the aluminum alloy rolled plate to form the imitation copper-colored fluorocarbon paint coating;

[0065] S10: drying and curing the imitation copper-colored fluorocarbon paint coating to obtain an imitation copper-colored aluminum plate;

[0066] S11: Use wind-assisted etching equipment to perform wire drawing processing on the imitation copper aluminum plate.

[0067] The solution temperature of the homogenous heat treatment is controlled at 540°C to 575°C, the solution time is 40 seconds to 60 minutes, and low quenching rate quenching is adopted, and the rate is controlled at 30 to 80°C / s.

[0068] After multiple cold rolling processes, the aluminum coil is cold rolled to a predetermined thickness of 1 mm and then completely recrystallized and annealed at 400° C. The annealed aluminum coil is cold rolled to a finished thickness of 0.75 mm, with a work hardening rate of 25%.

[0069] The total rolling rate of step S04 is 50-80%, and the coiling temperature of the final pass is below 100°C. The annealing of step 05 includes a heating process at above 100°C / min, a process of maintaining at 380-550°C for less than 10 minutes, and a process at above 100°C / min.

[0070] Before step S11, the non-etched position on the surface of the imitation copper-aluminum plate needs to be protected. The specific method is A1. coating the non-etched position on the surface of the imitation copper-aluminum plate with a photosensitive material; masking and developing the imitation copper-aluminum plate with a film to expose the etched position of the workpiece.

[0071] Homogenization, also known as homogenization, is the process of micronizing and homogenizing the dispersed matter in the suspension (or emulsion) system. This treatment simultaneously reduces the size of the dispersed matter and improves the uniformity of the dispersed matter distribution.

[0072] Fluorocarbon paint refers to a coating with fluororesin as its primary film-forming substance; it is also known as fluorocarbon paint, fluorine coating, or fluororesin coating. Among various coatings, fluororesin coatings possess exceptionally superior properties due to the high electronegativity of the introduced fluorine element and the strong carbon-fluorine bond energy. These properties include weather resistance, heat resistance, low-temperature resistance, chemical resistance, and unique non-stick and low-friction properties. After decades of rapid development, fluororesin coatings have found widespread application in various fields including construction, the chemical industry, electrical and electronics, machinery, aerospace, and household products. They have become the coating brand with the highest overall performance, following high-performance coatings such as acrylic, polyurethane, and silicone coatings. The three most widely used fluororesin coatings are PTFE, PVDF, and FEVE.

[0073] Wherein, in the above technical solution, in step S11, the wind-assisted etching device includes a clamping mechanism 01, an etching mechanism 02, an etching liquid tray 03 and a blowing mechanism 04, the clamping mechanism 01 is used to clamp the imitation copper-aluminum plate downward, the etching mechanism 02 is located directly below the clamping mechanism 01, the blowing mechanism 04 is located below the side of the etching mechanism 02, and the wind direction of the blowing mechanism 04 is toward the surface of the imitation copper-aluminum plate clamped by the clamping mechanism 01, the etching liquid tray 03 is located directly below the etching mechanism 02, and the etching liquid tray 03 contains etching liquid;

[0074] The etching mechanism 02 includes a wire frame 021, an etching line 022 and a lifting rod 023. The wire frame 021 is a square frame. The area of ​​the wire frame 021 is larger than the area of ​​the clamping mechanism. The wire frame 021 is provided with etching lines 022 arranged according to the drawing pattern. The lifting rod 023 is fixed on the side of the wire frame 021 and is used to lift the wire frame 021 to the etching liquid tray 03 to immerse the etching line 022 and enable the etching line 022 to fit onto the surface of the imitation copper-aluminum plate. The etching line 022 can be immersed in the etching liquid.

[0075] like Figure 2-5 As shown, when in use, the imitation copper-aluminum plate is buckled on the clamping mechanism 01, the lifting rod 023 is lowered, and the etching line 022 in the wire frame 021 is immersed in the etching liquid in the etching liquid tray 03, the lifting rod 023 is lifted to press the etching line 022 against the surface of the imitation copper-aluminum plate, and the air blowing mechanism 04 is turned on to blow the etching liquid on the etching line 022 to the surface of the imitation copper-aluminum plate for etching; after the etching molding is completed, the lifting rod 023 is lowered and evacuated from the surface of the imitation copper-aluminum plate. At this time, the air pressure of the air blowing mechanism 04 can be adjusted to ensure that the etching liquid leaves the workpiece surface in time to avoid the consequences of excessive etching of multiple workpieces; and after the etching liquid is removed, the workpiece is post-processed, which at least includes alkali washing, water washing, polishing and other processes to ensure that the etching liquid and photosensitive material on the workpiece are completely removed and the workpiece is more shiny after post-processing, so as to facilitate subsequent processes.

[0076] Etching fluid is a raw material used in copperplate engraving. It erodes the material's properties to create the engraving. Theoretically, any reagent that oxidizes steel to produce soluble copper salts can be used to etch copper-clad boards. However, considerations must be taken into account, including damage to the resist, etching speed, etching coefficient, copper dissolving capacity, solution regeneration and copper recovery, environmental protection, and economic benefits.

[0077] Furthermore, in the above technical solution, the etching wire 022 is a rope twisted from a glass fiber material, and the surface of the etching wire 022 has a hair scale structure.

[0078] Fiberglass is an inorganic, non-metallic material with excellent properties. Available in a wide variety of materials, it offers excellent insulation, heat resistance, corrosion resistance, and mechanical strength. It is manufactured from six minerals: pyrophyllite, quartz sand, limestone, dolomite, colemanite, and magnesiaite, through processes such as high-temperature melting, drawing, winding, and weaving. The diameter of a single fiber ranges from a few microns to more than 20 microns, equivalent to 1 / 20 to 1 / 5 the diameter of a human hair. Each fiber strand is composed of hundreds or even thousands of individual filaments. Fiberglass is commonly used as a reinforcing material in composite materials, as an electrical and thermal insulation material, and in circuit boards, among other applications in the national economy.

[0079] Asbestos, also known as "asbestos," is a commercial term for silicate mineral products that exhibit high tensile strength, flexibility, chemical and thermal resistance, electrical insulation, and spinnability. It is a general term for naturally occurring fibrous silicate minerals. It falls into two categories, encompassing a total of six minerals (including serpentine, hornblende, actinolite, anthophyllite, amosite, and tremolite). Asbestos is composed of fiber bundles, which are in turn composed of very long, thin, separable fibers.

[0080] Furthermore, in the above technical solution, the hair dryer structure 04 has a plurality of air outlets in a uniform array, and the air outlets are connected to the hair dryer through air ducts.

[0081] like Figure 6 As shown, specifically, each air outlet is connected to an on-off valve, which is used to control the opening and closing of the air outlet, so that the staff can start the corresponding number and position of air outlets to work according to needs, so that the etching liquid can not only be blown in the direction away from the blower mechanism 04, but also prevent the etching liquid from splashing in places where etching is not required.

[0082] Furthermore, in the above technical solution, the angle between the blowing direction of the air outlet and the clamping mechanism 01 is 20°~45°, and the air blowing mechanism 04 is symmetrically arranged on both sides of the clamping mechanism 01.

[0083] Furthermore, in the above technical solution, the hair dryer of the hair dryer structure 04 blows inert gas, and the wind speed of the hair dryer is controlled between 0.2 and 0.9 m / s.

[0084] Among them, in the above technical solution, the size needs to be reviewed after step S07, and the review method is:

[0085] Step 1: Check whether the cut aluminum alloy rolled plate is consistent with the size. If the size is consistent, proceed to step S08; if the size is not consistent, proceed to the next step;

[0086] Step 2: Adjust the locator so that the calibrated line is closer to the required size, and then proceed to step 1;

[0087] Among them, the size error of the aluminum alloy rolled plate after cutting is less than 1.0mm.

[0088] Among them, in the above technical solution, the components of the aluminum alloy ingot include: Al, Mg, Fe, and Si, among which Al: 4.8~6.5wt.%, Mg: 0.5~0.95wt.%, Fe: 0.1~0.8wt.%, Si: 0.06~0.2wt.%, and the content of other individual trace elements is controlled at 0.1wt.% or below.

[0089] Among them, in the above technical solution, after step S11, the imitation copper-aluminum plate is cut according to the position of the design drawing using a corner punching machine, and after cutting, the imitation copper-aluminum plate is bent according to the design.

[0090] Imitation copper-aluminum plates cannot be bent repeatedly to avoid fatigue damage. They can be bent at most twice, with an allowable size error of +1.0mm. After bending, use the back of a wallpaper knife to lightly scratch the protective film of the bent composite board. Be careful not to scratch the board surface. The position should be about 4mm away from the bend, and then tear off the protective film.

[0091] In the above technical solution, in step S09, the entire process of "spraying the imitation copper-colored fluorocarbon paint with an electrostatic sprayer" requires spraying the imitation copper-colored fluorocarbon paint at least three times.

[0092] Finally, the imitation copper-aluminum plates are assembled and reinforced:

[0093] Use an isopropyl alcohol / water mixture (1:1) or xylene to clean the copper-aluminum plate, the frame, the reinforcement and the 3M tape.

[0094] First, bond the 3M tape to the attached frame and reinforcement ribs. During operation, do not touch the 3M tape after the film is removed or the cleaned surface with your hands or other objects;

[0095] Place the attached frame with 3M tape into the imitation copper-aluminum plate box, tap the attached frame with your hands or glue to make the bent edge of the composite plate enter the hook groove of the attached frame, so that the 3M tape and the composite plate are firmly bonded, and the gap between the folded edge of the composite plate is less than 0.4mm;

[0096] Drill holes using a drilling template according to the design drawing. The distance between blind rivets is 350mm. The holes are arranged from both ends to the middle. Install self-tapping screws or blind rivets.

[0097] The reinforcement ribs should be tightly fitted to the composite board. Self-tapping screws or blind rivets should be used at the intersection of the two ends of the reinforcement ribs and the folded edges of the composite board. Be careful not to damage the board surface.

[0098] The allowable deviation of the length and width of the assembled plate is 1.5mm; the allowable deviation of the diagonal size is ≤2.5mm; the plate thickness is 0.5mm; the allowable deviation of the corner plate angle is 0.5, and the product will be unqualified if it exceeds this data

[0099] Review whether each processing step is carried out as required and whether the processing results are qualified.

[0100] After passing the inspection, the imitation copper and aluminum plates are placed opposite each other and tilted 80 degrees to the horizontal on the designated finished product rack. Note the temperature requirements for using 3M tape:

[0101] 1. T>10°C, use 4950 tape;

[0102] 2. 0°C≤T≤10°C, use 4951 tape:

[0103] 3. When the ambient temperature is below 0°C, 3M tape bonding is not allowed.

[0104] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any modifications or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
