[0030] Several preferred embodiments or application examples are listed below to help those skilled in the art better understand the technical content of the present invention and the technical contribution made by the present invention relative to the prior art: Preferred embodiment one: like Figure 1 As shown, the present invention provides a method for processing curved surface relief based on a metal sheet, comprising the following steps: S1. Select a metal sheet within a preset thickness range, cut the metal sheet according to the preset image contour, and obtain a first metal sheet after cutting; in this embodiment, the preset thickness range in step S1 is 3mm-6mm, preferably 5mm. After a large number of experiments, it is found that the metal sheet with a thickness within the above parameter range can have a certain flexibility while meeting the structural strength, and can complete bending deformation and embossing stamping. The cutting in step S1 uses high-precision laser equipment. Using high-precision laser equipment for cutting can improve product consistency.

[0031] Specifically, the Christmas tree enclosure adopts the iron plate integral cutting process to ensure the size accuracy and shape consistency of each part. This cutting method provides high-quality basic components for subsequent assembly and processing, ensuring the overall quality and stability of the tree enclosure.

[0032] S2. Perform hydraulic or stamping treatment on the edge position of one side of the first metal sheet to form a convex portion or a concave portion at the edge position; perform strengthening treatment on the other side edges of the first metal sheet except the one side; wherein the pressure value range in the hydraulic or stamping treatment is 150t-200t, preferably 200t.

[0033] The strengthening treatment in step S2 includes one or more of folding treatment, welding wire treatment, edging wire treatment, curling treatment and welding cold strip treatment.

[0034] Specifically, the edges of the iron plate are folded left and right to increase the strength and stability of the iron plate. The structure is further reinforced by welding iron wires. The distribution and welding positions of the iron wires are carefully designed to ensure that the tree enclosure will not be easily deformed when subjected to external forces. Thickened cold plate strips are used in some key parts to further enhance the overall strength of the tree enclosure so that it can better maintain its shape. Among them, in the left and right folding process, the 10mm-15mm distance from the edge is folded inward to form a folded edge.

[0035] Bottom edging wire / round tube treatment: The bottom is treated with edging wire or round tube treatment, which not only enhances the bearing capacity and stability of the bottom, but also makes the tree fence more stable and not easy to fall when placed on the ground. This design can effectively protect the integrity of the tree fence during use and extend its service life; specifically, the bottom is 8mm-12mm away from the edge for edging wire or round tube treatment.

[0036] Top pressed texture lines: The top is made of texture lines to form raised or sunken lines. This design has a dual purpose. On the one hand, these lines can significantly strengthen the strength of the iron plate, so that the top of the tree enclosure will not be easily deformed when subjected to external forces (such as the weight of decorative items, collisions, etc.); on the other hand, these texture lines can make it easier to carry out mechanized / efficient surface color effects such as silk screen printing, printing, and water transfer printing while maintaining the flatness of the plane and the integrity of the outline of the tree enclosure, providing better conditions for the appearance decoration of the tree enclosure. Among them, the distance between the top and the line is not less than 5 mm, and generally 8 mm is used.

[0037] A preset area inside the first metal sheet is subjected to hydraulic or stamping treatment to form a relief pattern in the preset area to obtain a second metal sheet; in this embodiment, the relief pattern is a Christmas tree pattern; wherein the pressure value range of the hydraulic or stamping treatment is 150t-200t, preferably 200t.

[0038] It should be noted that the two hydraulic treatments can be performed simultaneously or in steps.

[0039] Furthermore, step S2 further includes: The outer surface of the second metal sheet is cleaned and polished in sequence, and then the outer surface of the second metal sheet is primed and printed in sequence, and then the process proceeds to step S3.

[0040] S3, bending the second metal sheet obtained in step S2 to obtain a curved metal sheet monomer with a relief pattern.

[0041] After step S3, the following steps are also included: Two or more curved metal sheet monomers with embossed patterns are sequentially connected end to end to form a ring-shaped target product. In this embodiment, the target product is a Christmas tree ring.

[0042] In this embodiment, the manufacturing process is as follows: 1. Iron plate preparation According to the design requirements, iron plates of suitable thickness and material are selected, and high-precision laser cutting equipment is used to cut and cut materials according to the predetermined size. The precision is strictly controlled during the cutting process to ensure that the dimensional error of each iron plate component is within the allowable range.

[0043] 2. Structural processing The cut iron plate is folded on the left and right sides, and the folding angle and length are precisely controlled according to the design requirements. Then, the iron wire is welded at a specific position according to the design plan. The welding quality is guaranteed during the welding process to avoid problems such as cold welding. For the parts that need to use thickened cold strips, the cold strips are accurately installed and fixed.

[0044] The main iron plate is hydraulically / stamped to enhance the strength of the iron plate and the relief pattern effect. Professional embossing equipment is used to press out the relief texture lines according to the design pattern and depth to ensure the clarity and uniformity of the lines. The bottom of the iron plate is treated with edging wire or curling effect. The edging wire is tightly around the edge of the iron plate, and the round tube is firmly combined with the bottom of the iron plate to ensure the stability of the bottom structure.

[0045] 3. Surface preparation After completing the above structural processing, the tree enclosure is prepared for surface treatment, including cleaning and polishing, to ensure that the surface is flat and smooth, creating good conditions for subsequent surface color effect processing such as silk screen printing, printing, and water transfer printing.

[0046] 4. Surface color effect processing The key lies in the positioning of the top (in the direction of the special-shaped edge).

[0047] 5. Plane concave / molding / direct assembly of 8 / 12 / 16 pieces, etc., docking, proofreading and assembly of three-dimensional tree enclosures.

[0048] How to use: Splice and assemble the formed grouped embryos into a tree fence. Wrap around the trunk of the Christmas tree, and because of the stable design of its bottom, it can be placed directly on the ground. If multiple tree fences are needed, they can be spliced ​​according to actual needs to form a larger tree fence decoration. During use, the tree fence can maintain good stability and appearance integrity with its unique structural design, providing a long-lasting and beautiful decorative effect for the Christmas tree.
