[0043] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings.

[0044] like Figure 1 As shown, the processing method of the square bead of the present invention includes the following steps:

[0045] (1) Material cutting to obtain metal forming parts. This step includes: melting gold material and alloy in a certain proportion into a gold melting cup to form the first gold liquid, stirring with a first tool for a certain time and then pouring it into a graphite tank to form gold ingots, placing the gold ingots into a casting mold and heating to form the second gold liquid, stirring with a second tool for a certain time, and then starting to cast strips to form metal forming parts.

[0046] (2) The metal forming part is subjected to sheet pressing to obtain a first sheet. This step includes: using a sheet pressing machine to press the metal forming part into a first sheet of a specific size.

[0047] (3) The first sheet is subjected to a first annealing process to obtain the second sheet. This step includes: placing the first sheet into the first furnace for a first annealing process to obtain the second sheet.

[0048] (4) Cut the second sheet to obtain the target sheet. This step includes: using a cutting machine to cut the second sheet into target sheets of a specific size.

[0049] (5) The target sheet is subjected to pipe welding to obtain a hollow tube. This step includes: putting the target sheet into a pipe welding machine and welding the target sheet into a hollow tube with a specific aperture.

[0050] (6) The hollow tube is drawn to obtain a round tube. This step includes: passing the hollow tube through a specific mandrel to draw the hollow tube into a round tube with a specific aperture.

[0051] (7) Perform a second annealing process on the round tube to obtain the target round tube. This step includes: placing the round tube into a second furnace for a second annealing process to obtain the target round tube.

[0052] (8) The target round tube is subjected to bead hammering to obtain the first bead body. This step includes: using an automatic cutting bead die to hammer the target round tube to obtain the first bead body.

[0053] (9) The first bead is subjected to a third annealing process to obtain the second bead. This step includes: using a third furnace to perform a third annealing process on the first bead to obtain the second bead.

[0054] (10) The second bead is ground to obtain the third bead 1 (e.g. Figure 2 (As shown). This step includes: placing the second bead in a grinding disc for grinding to obtain the third bead 1.

[0055] (11) For the third bead 1 (e.g.) Figure 2The third bead 1 is subjected to a fourth annealing process (as shown) to obtain the fourth bead. This step includes: performing a fourth annealing process on the third bead 1 in a fourth furnace to obtain the fourth bead.

[0056] (12) The fourth bead is subjected to axial extrusion to obtain the fifth bead 2 (e.g. Figure 3 (As shown). This step includes: extruding the fourth bead through an extrusion deformation process to obtain the fifth bead 2.

[0057] (13) For the fifth bead 2 (as Figure 3 (As shown) undergo radial hammering to obtain the first square bead 3 (as shown). Figure 4 , Figure 5 (As shown). This step includes: performing radial hammering along the circumference of the fifth bead 2 to generate multiple planar portions 4 in the circumference of the fifth bead 2, thereby obtaining the first square bead 3.

[0058] In one specific embodiment, the first square bead 3 is subjected to an ice-batch treatment to obtain the target square bead 5 (e.g., 6). Figure 7 (As shown). Among them, the flat part 4 of the target square bead 5 has a mirror effect, which can effectively improve the brightness and neatness of the flat part 4.

[0059] In a specific embodiment, such as Figures 3-5 As shown, before the step of radially hammering the fifth bead 2 to obtain the first square bead 3, the method further includes: axially fixing the first and second ends of the fifth bead 2 along the axial direction, so that the axial dimension of the fifth bead 2 has no room for elongation during the radial hammering process. In this way, the axial dimension of the fifth bead 2 can be prevented from extending outward during the radial hammering process.

[0060] In a specific embodiment, such as Figure 3 As shown, the steps for axially fixing the first and second ends of the fifth bead 2 along the axial direction include: inserting a wire into the axial hole 6 of the fifth bead 2, using a laser machine to fix the wire to the first and second ends of the fifth bead 2 along the axial direction, and using a welding machine to weld the wire so that the wire at the first end and the second end of the fifth bead 2 along the axial direction both form solid beads. The diameter of the solid bead is larger than the diameter of the axial hole 6, which can effectively prevent the axial dimension of the fifth bead 2 from extending outward, and is simple and efficient.

[0061] In a specific embodiment, such as Figures 3-7As shown, after the step of radially hammering the fifth bead 2 to obtain the first square bead, and before the step of icing the first square bead 3 to obtain the target square bead 5, the process further includes: removing the solid beads at the first and second ends of the fifth bead 2 along the axial direction, as well as the thread inside the axial hole 6 of the fifth bead 2. This facilitates the icing process of the first square bead 3 to obtain the target square bead 5. For example, the axial hole 6 facilitates the stringing of the first square beads 3 together.

[0062] In a specific embodiment, such as Figures 3-5 As shown, the step of performing radial hammering on the fifth bead 2 to obtain the first square bead 3 includes: performing radial hammering on the fifth bead 2 along its circumference to generate multiple planar parts 4 in the circumference of the fifth bead 2, thereby obtaining the first square bead 3. This method is simple, efficient, and aesthetically pleasing.

[0063] In a specific embodiment, such as Figures 4-7 As shown, the steps of performing ice-on treatment on the first square bead 3 to obtain the target square bead 5 include: using a specific tool to string together multiple first square beads 3 to form a square bead string, performing ice-on treatment on the square bead string to obtain the target square bead 5, which facilitates the ice-on treatment of multiple square beads and the ice-on treatment of each square bead.

[0064] In one specific embodiment, the tool includes an adhesive strip that is elastic, making it easy to fix the square bead string to the outer surface of the carving barrel in subsequent steps. It also has a simple structure and is easy to use.

[0065] In one specific embodiment, the step of performing an ice-brush treatment on the square bead string to obtain the target square bead 5 includes:

[0066] The first step is to determine the ice-cold bread machine. The ice-cold bread machine includes a compressor, a stencil barrel, and a blade body. The blade body is located outside the stencil barrel. The stencil barrel is connected to the power output end and is used to rotate under the drive of the power output end. The stencil barrel is filled with refrigerant, and the compressor is used to cool the outer surface of the stencil barrel through the refrigerant.

[0067] The second step is to attach the square bead string to the outer surface of the carving barrel. The two ends of the adhesive strip are used to fix the square bead string to the outer surface of the carving barrel along its circumference. Depending on the actual needs, multiple positioning holes can be spaced out along the circumference of the carving barrel's outer surface, and the two ends of the adhesive strip can be placed in two different positioning holes.

[0068] The third step involves placing liquid on the outer surfaces of the square bead string and the carving barrel. A compressor uses refrigerant to freeze the liquid into a solid, which then secures the square bead string to the outer surface of the carving barrel. Using a solid material facilitates further fixation of the square bead string to the outer surface of the carving barrel, improving its stability and reliability, and also facilitating subsequent use of the cutting tool to work on the flat surface 4 (such as...). Figure 4 , Figure 5 (As shown) Performing serration processing and machining to a predetermined depth can avoid the vibration caused by friction between the cutter body and the serration surface, resulting in tool marks and effectively improving the brightness and cleanliness of the serration surface.

[0069] The fourth step involves using the blade to work on one of the flat surfaces 4 of the first square bead 3 on the square bead string (as shown). Figure 4 , Figure 5 (As shown) Perform machining on the surface and machine to the predetermined depth to achieve a mirror finish.

[0070] The fifth step involves machining the other flat surfaces 4 of the first square bead 3 on the square bead string to a predetermined depth, thereby obtaining the target square bead 5 (e.g., ...). Figures 4-7 (As shown). In this process, after one of the flat surfaces 4 of the first square bead 3 on the square bead string is engraved to a predetermined depth, the two ends of the adhesive strip are released from the positioning hole, and the first square bead 3 on the square bead string is rotated at a certain angle. This allows for engraving of the other flat surface 4 of the first square bead 3 on the square bead string to be engraved to a predetermined depth. This process is repeated for all flat surfaces 4 of the first square bead 3 on the square bead string, resulting in the target square bead 5. Then, the solid on the outer surface of the engraving barrel is melted, and the square bead string is removed and dried.

[0071] In one specific embodiment, there are multiple square bead strings arranged circumferentially along the embroidery barrel, which facilitates the icing process of multiple square bead strings.

[0072] In one specific embodiment, the liquid is water, which is convenient to use and economical. The solid is ice.

[0073] In one specific embodiment, the first, third, and fourth furnace bodies all include intermediate annealing furnaces, which soften the metal material, facilitating subsequent processing and preventing oxidation.

In another specific embodiment, the second furnace body includes a welded chain tunnel furnace, which facilitates the annealing of round tubes, providing rapid annealing speed and ensuring simultaneous heating of the inner and outer surfaces of the tube, resulting in high temperature uniformity, no deformation, no discoloration, and stable quality.

[0074] In one specific embodiment, the temperature of the first annealing is 600-650 degrees Celsius, and the time of the first annealing is 5-10 minutes. This can reduce the hardness of the second sheet, improve machinability, reduce residual stress, stabilize dimensions, reduce deformation and crack tendency, refine grains, adjust microstructure, eliminate microstructural defects, homogenize material microstructure and composition, improve material properties, or prepare microstructure for subsequent heat treatment.

[0076] In one specific embodiment, the third annealing temperature is 600–650 degrees Celsius, and the annealing time is 25–30 minutes. This reduces the hardness of the second beads, improves machinability, reduces residual stress, stabilizes dimensions, reduces deformation and cracking tendency, refines grains, adjusts the microstructure, eliminates microstructural defects, homogenizes the material microstructure and composition, and improves material properties or prepares the microstructure for subsequent heat treatment. Furthermore, the use of direct water cooling and compressed air drying in the third annealing process further improves the metallic quality and heat treatment effect of the second beads.

[0077] In one specific embodiment, the fourth annealing temperature is 600-650 degrees Celsius, and the fourth annealing time is 25-30 minutes. This can reduce the hardness of the fourth bead, improve machinability, reduce residual stress, stabilize dimensions, reduce deformation and crack tendency, refine grains, adjust microstructure, eliminate microstructural defects, homogenize material microstructure and composition, and improve material properties.
