Description

Technical Field

[0001] This invention relates to the field of carving technology, and in particular to the application of Yunjin goldwork in fine lines and relief carving. Background Technology

[0002] Yunjin, originating from the traditional Chinese brocade weaving technique and born from kesi (silk tapestry), is renowned for its intricate and ornate patterns and unique textures. The magnificent brocade texture of Yunjin has gradually been applied to jewelry design, combining with various production techniques to form the "Yunjin Gold" gold craftsmanship. This technique creates a beautiful, brocade-like fabric texture, adding unique aesthetic appeal and traditional cultural value to the jewelry. The Yunjin Gold craftsmanship involves using CNC machining combined with traditional patterns to carve brocade-like designs onto a smooth gold surface. Through intricate carving, it creates a visual effect of immense value, or the texture can be directly pressed out using a hydraulic pressing process.

[0003] Previously, the Yunjin gold carving technique could only be used to carve on a large gold surface, resulting in a product that lacked a strong three-dimensional effect and sufficient visual impact.

[0004] The original Yunjin gold craftsmanship employed techniques such as hydraulic pressing, lost-wax casting, and hand engraving to achieve a brocade effect on both flat and curved surfaces. Hydraulic pressing involves vertically pressing and stretching the metal, offering advantages such as rapid forming and clear texture. However, the vertical pressing process can cause a blurred visual effect on the sides of curved gold jewelry. Lost-wax casting can lead to stretching and shrinkage of the wax piece during production, resulting in deformation. Hand engraving, with its drawing and chiseling processes, can result in irregular lines and a lack of three-dimensionality.

[0005] This invention avoids the drawbacks of the original process, making the entire gold jewelry product have a clear and smooth brocade effect from any angle.

[0006] Therefore, we propose to apply the Yunjin gold technique to fine lines and relief carving to solve the existing problems. Summary of the Invention

[0007] The purpose of this invention is to address the problems existing in the background art by proposing the application of Yunjin goldwork in fine lines and relief carving.

[0008] To achieve the above objectives, the present invention provides the following technical solution: the application of Yunjin gold craftsmanship in relief carving, including fine carving using a 0.2mm carving knife to carve 0.2mm fine lines on the surface of the gold blank. This method is relief carving. Then, a 0.08R ball-head carving knife is used to carve the curved surface of the gold blank. By adjusting the angle of the 0.08R ball-head carving knife, each angle of the curved surface is carved at a 90-degree angle with the carving knife. This breaks through the original process bottleneck, so that the entire gold jewelry product has a clear and smooth brocade effect from any angle.

[0009] The application of the brocade gold process on thin wires. After carving out 0.2MM thin wires from the gold embryo, a 0.08R ball-nose engraving tool is used to engrave bright and sanded surfaces on the 0.2MM thin wires through staggered adjustment at a 45-degree angle, thus forming a double-layer visual effect combining brocade gold and the Chinese character "Fu".

[0010] Preferably, the fine engraving preparation of the gold embryo includes design drawing, material preparation and preliminary engraving. The design drawing includes drawing detailed drawings according to requirements, including the shape, size, pattern and required engraving details of the jewelry. The material preparation includes a 0.2mm engraving tool, a 0.08R ball-nose engraving tool and a magnifying lens. The preliminary engraving uses rough engraving tools such as files and saws to engrave the material into a rough designed shape.

[0011] Preferably, the method for engraving 0.2mm thin wires: Fix the preliminarily engraved gold embryo on the engraving table, design a pattern on the gold embryo through the design drawing, and then use a 0.2mm engraving tool to engrave out the 0.2mm thin wires along the outline of the designed pattern.

[0012] Preferably, the fixing method of the gold embryo includes temporarily fixing it on the engraving table with fixing glue. After fixing the material, adjust its position to ensure that the material is in a position easily accessible by the engraving tool while maintaining the stability of the material. Before starting engraving, gently shake the material to check for looseness.

[0013] Preferably, the arc surface engraving method designs a pattern on the gold embryo through the design drawing, uses a 0.08R ball-nose engraving tool to start the preliminary contour engraving on the gold surface. At this time, adjust the angle of the engraving tool so that the tool tip forms a 90-degree angle with the engraving surface, move the engraving tool slowly and steadily, and engrave according to the designed pattern. When engraving the arc surface, it is necessary to continuously adjust the angle of the engraving tool to ensure that each point can be precisely engraved. On the basis of the preliminary engraving, further refine the details of the pattern, carefully carve each arc surface, and continuously adjust the angle of the engraving tool to ensure that each angle can reach 90 degrees, so as to achieve a uniform engraving effect.

[0014] Preferably, the thin wire engraving includes drawing a preliminary design pattern of brocade gold and the Chinese character "Fu" on the gold embryo, using an erasable marker or a slight scratch to outline the design contour, and using a 0.08R ball-nose engraving tool to perform staggered engraving at a 45-degree angle on the already engraved 0.2mm thin wires. During the 45-degree angle engraving process, by adjusting the engraving depth and strength, two different textures of bright and sanded surfaces are presented on the thin wires.

[0015] Preferably, after the fine line is engraved, the details of the engraving are carefully inspected to ensure that all the lines are in accordance with the design pattern. Minor adjustments are made to the unsatisfactory parts until the ideal effect is achieved. Finally, the finished product is polished.

[0016] Preferably, the polishing includes, after the engraving is completed, using abrasive papers of different thicknesses to polish the surface of the jewelry to remove the burrs and unevenness generated during the engraving process. Finally, a polishing cloth wheel and polishing paste are used to polish the jewelry to make its surface present a mirror-like luster.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0018] The application and combination of the brocade gold process of the present invention on the fine line and the relief have the following:

[0019] Improve clarity and fineness: By carving on the 0.2MM relief fine line, the technology of the present invention significantly improves the clarity and fineness of the brocade gold process. The precise engraving of the fine line makes the pattern on the surface of the jewelry more delicate and the details more abundant;

[0020] Enhance the three-dimensional sense: By using the precision carving process to carve on the arc surface and the relief, the technology of the present invention makes the gold jewelry products present a clear and smooth brocade effect at any angle, greatly enhancing the three-dimensional sense and visual impact of the products;

[0021] Optimize the visual effect: By staggering and adjusting at a 45-degree angle, a bright surface and a sand surface are engraved on the 0.2MM fine line, forming a double-layer visual effect of the combination of brocade gold and the Chinese character "Fu". The use of this visual difference makes the jewelry pattern more vivid and has a sense of hierarchy;

[0022] Improve the product quality: The technology of the present invention avoids the disadvantages in the traditional process, such as the blurred visual effect of the oil pressure process, the deformation problem of the lost wax method, and the irregular lines of the manual chasing process, thereby improving the overall quality and stability of the product;

[0023] Improve the market competitiveness: The brocade gold jewelry produced by the technology of the present invention has stronger competitiveness and attractiveness in the market due to its unique beauty and high quality, and can meet the pursuit of consumers for high-quality jewelry; [[ID=​​​​​​​​

[0026] Figure 1 This is a schematic diagram of the structure of the present invention;

[0027] Figure 2 This is a schematic diagram of the actual product of the present invention. Detailed Implementation

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Example 1

[0030] like Figure 1 As shown, the application of the Yunjin gold craftsmanship proposed in this invention in fine lines and relief carving includes fine carving using a 0.2mm carving knife to carve 0.2mm fine lines on the surface of the gold blank. This method is relief carving. Then, a 0.08R ball-head carving knife is used to carve the curved surface of the gold blank. By adjusting the angle of the 0.08R ball-head carving knife, every angle of the curved surface is carved at a 90-degree angle with the carving knife. This breaks through the original process bottleneck, so that the entire gold jewelry product has a clear and smooth brocade effect from any angle.

[0031] Based on Example 1: The fine carving preparation of the gold blank includes design drawings, material preparation and preliminary carving. The design drawings include detailed drawings drawn according to the requirements, including the shape, size, pattern and carving details required for the jewelry. The material preparation includes a 0.2mm carving knife, a 0.08R ball-end carving knife and a magnifying lens. The preliminary carving uses rough carving tools, such as files and saws, to carve the material into the approximate design shape. This stage mainly removes excess material and forms a basic outline.

[0032] The pre-carved gold blank is then fixed on the carving table. The design is then drawn on the gold blank according to the design drawings. Using a 0.2mm carving knife, fine lines of 0.2mm are carved along the outline of the design. These lines will form the basic framework of the design. Keep your hand steady and apply even pressure to ensure that the depth of the lines is consistent, so as to ensure the accuracy and consistency of the lines.

[0033] The gold blank is fixed by using adhesive to temporarily fix it to the engraving table. The method of fixing with adhesive is as follows: Select a suitable adhesive: Based on the characteristics of gold, select a suitable adhesive. This adhesive should be non-toxic, non-corrosive to gold, and provide sufficient adhesion after curing;

[0034] Clean the surface of the material: Use alcohol or other suitable cleaner to clean the surface of the gold material to ensure that there is no oil or dust so that the adhesive can bond better;

[0035] Prepare tools: Prepare a small brush or dropper for applying the fixative;

[0036] Apply the fixing adhesive: Use a brush or dropper to apply a thin layer of fixing adhesive to the areas of the gold material that need to be fixed. Be careful not to use too much, as this may affect the engraving.

[0037] Material placement: Place the gold material, coated with adhesive, in the correct position on the engraving table;

[0038] Press to secure: Gently press the material to ensure it adheres firmly to the countertop;

[0039] Wait for curing: Follow the instructions on the adhesive to allow it to cure. This step may take anywhere from a few minutes to several tens of minutes, depending on the type of adhesive.

[0040] Check for secure fixation: After the adhesive has cured, gently shake the material to check if it is securely fixed. If necessary, add more adhesive and press it back in place.

[0041] After securing the material, adjust its position to ensure it is easily accessible to the carving tool while maintaining its stability. Before starting carving, gently shake the material to check for any looseness. If any looseness is found, readjust the securing tool until the material is completely stable. During carving, if slight movement of the material is observed, pause carving and make minor adjustments to secure it.

[0042] Steps to remove the adhesive after carving:

[0043] Softening the fixing adhesive: Use a suitable solvent (such as acetone) to soften the fixing adhesive. Be careful to choose a solvent that will not damage the gold material.

[0044] Careful removal: Use a small tool (such as a needle or tweezers) to carefully remove the adhesive.

[0045] Clean residue: Use a cleaning agent and a soft cloth to clean the material surface and remove all adhesive residue.

[0046] The arc surface engraving method designs patterns on the gold blank according to the design drawings. Using a 0.08R ball nose engraving tool, start the preliminary contour engraving on the gold surface. At this time, adjust the angle of the engraving tool so that the tool tip forms a 90-degree angle with the engraving surface. This can ensure the engraving depth and the clarity of the lines. Move the engraving tool slowly and steadily and engrave according to the designed pattern. When engraving the arc surface, continuously adjust the angle of the engraving tool to ensure that each point can be precisely engraved. On the basis of the preliminary engraving, further refine the details of the pattern, carefully carve each arc surface, and continuously adjust the angle of the engraving tool to ensure that each angle can reach 90 degrees, so as to achieve a uniform engraving effect.

[0047] Embodiment 2

[0048] As Figure 1 shown, the application of the brocade cloud gold process proposed by the present invention in thin lines and reliefs includes that after carving out 0.2MM thin lines on the gold blank, using a 0.08R ball nose engraving tool to engrave bright surfaces and sand surfaces on the 0.2MM thin lines through staggered adjustments at a 45-degree angle, thereby forming a double-layer visual effect combining brocade cloud gold and the character "Fu".

[0049] Based on Embodiment 2: The thin line engraving includes drawing the preliminary design patterns of brocade cloud gold and the character "Fu" on the gold blank, using erasable marks or slight scratches to outline the design contours, and using a 0.08R ball nose engraving tool to perform staggered engraving at a 45-degree angle on the already engraved 0.2mm thin lines, that is, engraving from different directions on the same thin line to form crossed textures. During the engraving at a 45-degree angle, by adjusting the engraving depth and strength, two different textures of bright surfaces and sand surfaces are presented on the thin lines.

[0050] Make some lines present bright surfaces (smooth and reflective), while the other part presents sand surfaces (rough and non-reflective). The bright surfaces are usually achieved by gentle engraving to make the line surfaces smooth, and the sand surfaces are achieved by slightly increasing the force to make the line surfaces have slight roughness. Subsequently, carefully check the details of the engraving to ensure that all lines are in accordance with the design patterns, and make minor adjustments to the unsatisfactory parts until the ideal effect is achieved. Finally, polish the finished product.

[0051] The polishing includes, after the engraving is completed, using abrasive papers of different thicknesses to polish the surface of the jewelry.

[0052] The specific steps of the polishing are as follows:

[0053] Select the appropriate abrasive paper: According to the roughness of the jewelry surface, select abrasive papers of appropriate thicknesses, usually starting from the coarser ones and gradually transitioning to the finer ones;

[0054] Preliminary polishing: Use coarse sandpaper (such as 400-600 grit) to polish the surface of the jewelry to remove obvious burrs and uneven areas;

[0055] Gradually refine: As the surface gradually becomes smoother, switch to finer sandpaper (such as 800-1200 grit) and continue sanding to reduce scratches and roughness;

[0056] Fine polishing: Finally, use very fine sandpaper (such as 2000 grit or higher) to finely polish the jewelry to make its surface smoother. Finally, check the surface of the jewelry under different lighting conditions to ensure that there are no burrs or scratches that have been missed. Polishing removes burrs and uneven areas generated during the carving process.

[0057] Finally, polish the jewelry using a polishing wheel and polishing compound. The polishing steps are as follows:

[0058] Prepare polishing tools: Prepare a polishing wheel and polishing compound. The polishing compound can be a metal polishing compound containing an oxidizing agent or a polishing compound suitable for precious metals;

[0059] Install the polishing cloth wheel: Install the polishing cloth wheel on the polishing machine and ensure that it runs smoothly. Apply an appropriate amount of polishing paste to the polishing cloth wheel and distribute it evenly on the surface of the cloth wheel.

[0060] Polishing: Hold the jewelry in the appropriate position and gently touch the surface of the polishing wheel to begin polishing. Keep the jewelry moving evenly on the wheel and avoid lingering in one spot for too long to prevent overheating or damage.

[0061] Gradually increase pressure: As the polishing process progresses, the pressure between the jewelry and the cloth wheel can be appropriately increased to improve the polishing effect;

[0062] Cleaning and Inspection: After polishing, use a clean cloth to clean the jewelry to remove any polishing residue and give it a mirror-like shine. Inspect the surface of the jewelry under good light to ensure that it has a uniform mirror-like shine.

[0063] After all the carving and polishing steps are completed, the jewelry is carefully inspected to ensure that it is clear and smooth from every angle, without any missed flaws. If necessary, the jewelry is cleaned and further surface treated, such as plating or adding a protective film.

[0064] The above specific embodiments are merely several preferred embodiments of the present invention. Based on the technical solutions of the present invention and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.

[0065] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention.
