Description

Technical Field

[0001] This invention relates to the field of jewelry processing technology, and in particular to a high-precision rotatable structure for gold jewelry. Background Technology

[0002] "Lulu Tong" is a type of auspicious jewelry, typically featuring round, hollow, and freely sliding beads, widely used in bracelet and necklace designs. Its origins can be traced back to the Neolithic Age, sharing close cultural ties with ancient jade tube ornaments and jade beads. Modern gold Lulu Tong are primarily produced using casting techniques to create a single piece, incorporating traditional auspicious elements such as the Pixiu (mythical creature), auspicious clouds, and the six-syllable mantra, making them highly popular among consumers.

[0003] However, most gold-plated bouncy beads currently on the market are produced using a casting process, which has certain shortcomings in terms of precision, hardness, and durability.

[0004] Simple structure: Most existing products adopt a one-piece casting method, which lacks a precise movable structure, resulting in limited decoration and functionality.

[0005] Quality issues: During the casting process, defects such as porosity and inclusions may occur, affecting the overall purity and visual appeal of the product.

[0006] Insufficient density and hardness: Compared to forging, cast metal has a lower density, and its strength and hardness are relatively lower, making it more prone to wear and deformation due to long-term wear.

[0007] Limited rotational performance: Due to the structural limitations of the one-piece casting, the existing Lulutong may not rotate smoothly enough, affecting the wearing experience.

[0008] To address this issue, we propose a high-precision rotatable structure for the Golden Road Connector. Summary of the Invention

[0009] The purpose of this invention is to address the problems existing in the background art by proposing a high-precision rotatable structure for the Golden Roadway.

[0010] To achieve the above objectives, the present invention provides the following technical solution: a high-precision rotatable structure gold road toy, comprising a main structure, which is a hollow ring, assembled from multiple independent components. The main structure is made of precious metal materials, including but not limited to gold, platinum or other precious metal alloys, which can achieve excellent wearing comfort while maintaining structural strength.

[0011] The rotating mechanism is composed of two contact surfaces on both sides of the main structure, which allows the main structure to rotate freely around the central axis. The friction between the contact surfaces is optimized to ensure smooth and uninterrupted rotation, while reducing wear caused by long-term wear and improving durability.

[0012] A fixed chain structure is provided inside the main structure, including a coin-shaped component with a through hole for the chain to pass through. The fixed chain structure is provided with a size adjustment to provide stable support for the chain, thereby preventing the main structure from sliding left and right when worn and improving the stability and comfort of wearing.

[0013] The manufacturing process involves using a die-casting process to create an initial blank for the main structure. This process involves injecting liquid metal into a mold under high pressure to form a highly dense blank, thereby improving material hardness and structural integrity. Subsequently, the main structure is machined by CNC computer numerical control to further enhance precision, achieving a seamless assembly effect. Finally, it is assembled as a whole using a seamless welding method to ensure that there are no visible weld points on the product surface, thus improving its aesthetics.

[0014] The surface decoration technique combines inlay and brocade gold techniques to create patterns and auspicious decorations on the surface of the main structure.

[0015] Preferably, the alloy melting temperature, mold temperature, and injection speed of the die-casting process are precisely controlled so that the product hardness reaches 80HV0.1 Vickers hardness, ensuring that it is not easily deformed or worn during long-term wear.

[0016] Preferably, the wall thickness of the main structure is controlled at 0.32mm to ensure that the product is lightweight and to reduce the amount of material used while maintaining sufficient strength, thereby improving wearing comfort and economy.

[0017] Preferably, the contact surface of the rotating mechanism is machined with high precision CNC and subjected to ultra-fine grinding and polishing processes to achieve a surface finish of Ra0.1 or less, thereby further optimizing the smoothness of rotation and reducing frictional resistance during long-term use.

[0018] Preferably, the copper coin component of the fixed chain structure is formed by CNC precision machining, and its shape and size are precisely calculated to ensure that it fits precisely with the main structure, so that the wearing chain remains fixed inside without affecting the overall rotation function, thereby improving the stability and safety of the wearing experience.

[0019] Preferably, the surface of the main structure is inlaid with gemstones, diamonds and other precious metal ornaments by means of reserved grooves and spot welding, so as to enhance the decorative and artistic value of the product.

[0020] Preferably, the surface of the main structure is made using the Yunjin Gold process. This process can be carried out by micro-carving, laser etching, and high-temperature sintering to form a three-dimensional relief and delicate textured decorative pattern on the metal surface. The pattern includes, but is not limited to, auspicious clouds, mythical beasts, the six-syllable mantra, and traditional auspicious symbols, to enhance the artistic beauty and cultural connotation of the product, while also improving the wearer's visual and tactile experience.

[0021] Preferably, the seamless welding process employs high-precision laser welding technology, using a laser beam to perform micron-level welding on the assembled components to ensure that the weld points are invisible, while simultaneously improving structural strength and giving it higher impact resistance and durability.

[0022] Preferably, the inner wall of the main structure and the contact surface of the rotating mechanism are treated with a nano-level coating. The coating may be a high wear-resistant ceramic coating, a diamond-like carbon coating, or a precious metal anti-oxidation coating, in order to reduce friction loss, improve rotational smoothness, and extend the product's service life.

[0023] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0024] This invention addresses the shortcomings of existing gold-plated roadblocks by proposing a novel gold-plated roadblock with a high-precision rotatable structure, offering the following technical advantages and improvements:

[0025] Die casting and CNC processes are used to improve precision and hardness: the initial blank is prepared by die casting, which increases the density and hardness of the product, so that the finished product reaches a Vickers hardness of 80HV0.1, enhancing wear resistance and deformation resistance. CNC precision machining of each part ensures that its surface is smooth and its fit is high, achieving a tight assembly effect.

[0026] High-precision rotatable structure: The multi-part assembly method enables the Lulutong to rotate smoothly. The rotating contact surface is only distributed on both sides, and the middle is hollow to reduce friction and make the rotation smoother.

[0027] Ultra-thin and lightweight design enhances wearing comfort: Through the use of high-hardness materials, an ultra-thin wall thickness of 0.32mm is achieved, making it lighter to wear while maintaining sufficient strength;

[0028] Innovative fixed chain structure: An internal copper coin fixing structure is added to effectively prevent the beads from sliding left and right during wearing, improving the stability and comfort of wearing;

[0029] Combining traditional craftsmanship to enhance aesthetics and cultural value: Employing inlay and brocade gold techniques makes the products more exquisite and endows them with richer cultural connotations.

[0030] Based on the traditional gold-plated tumbler, this invention improves the processing technology and structural design, giving the product advantages such as high precision, high hardness, rotatability, and lightweight comfort. It also enhances the wearing experience and visual aesthetics, making it highly competitive in the market and valuable for application. Attached Figure Description

[0036] 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.

[0037] Example 1

[0038] like Figure 1-5 As shown in the figure, the high-precision rotatable structure for gold-plated circuits proposed in this invention includes the following steps:

[0039] Step 1: Initial blank manufacturing

[0040] Material selection

[0041] High-purity gold or gold alloys are selected to ensure that the material has sufficient mechanical strength and wear resistance; the selected gold alloys have high corrosion resistance and excellent ductility, which can maintain their appearance and structural stability during long-term wear.

[0042] By employing appropriate casting formulas and optimizing metal fluidity and density, porosity and impurities can be reduced, thereby improving the quality of the final product. Precise control of casting temperature and pressure ensures the internal density of the metal, preventing casting defects from affecting the overall performance of the product.

[0043] Die casting process

[0044] Heating gold to above its melting point (e.g., above 1064°C) creates a highly fluid molten metal, which is beneficial for filling precision molds. This process ensures that the metal is completely melted through high-temperature heating, avoiding product defects caused by incomplete melting.

[0045] Under high-pressure injection (e.g., 100-200 MPa), molten metal is injected into a precision mold to form an initial blank, ensuring the compactness of the blank and minimizing porosity and impurities. The high-pressure injection process can effectively reduce the probability of bubble formation, ensure a smooth and flawless blank surface, and reduce the difficulty of subsequent processing.

[0046] Cool and remove the blank, remove burrs and flash, and ensure that the product dimensions meet the design requirements. The cooling process needs to be precisely controlled to prevent the metal from deforming due to uneven cooling.

[0047] This process ensures the internal density of the metal, increases the hardness of the final product to 80HV0.1, and provides a good physical basis for subsequent processing. This hardness ensures that the product has strong wear resistance during wear and use, and enhances its long-term stability.

[0048] Step 2: Precision CNC Machining

[0049] Precision engraving and size optimization

[0050] The initial blank is precisely sculpted using CNC machining to form the main structure of the "Lulu Tong" (a type of sculpted slab). This process uses high-precision CNC equipment to ensure that every detail accurately reproduces the design requirements.

[0051] The machining accuracy is controlled to ±0.01mm to ensure a tight fit between components and improve assembly precision. Such fine precision guarantees a perfect fit between components, ensuring that the final product has a high degree of precision and stability.

[0052] Further optimize the contact surface of the rotating mechanism to achieve a surface finish of Ra0.1 or lower, reducing friction and improving rotational smoothness. Through meticulous surface treatment, the coefficient of friction is reduced, ensuring smooth and unobstructed rotation and preventing wear problems caused by friction.

[0053] Internal copper coin structure processing

[0054] To enhance stability and comfort, CNC machining meticulously processes the internal structure of the main body, creating a coin-shaped fixing structure. This design ensures the chain can pass through smoothly while effectively preventing lateral slippage, thus enhancing stability during wear. The precision cutting technology of this structure guarantees a tight fit between the coin structure and the main body, improving both security and aesthetics. This precision cutting technology ensures a seamless connection between the coin structure and the main body, preventing gaps or looseness, thereby improving both stability and comfort when wearing.

[0055] The CNC high-precision cutting process is used to ensure that the copper coin structure fits tightly with the main body.

[0056] Step 3: Rotational Structure Optimization

[0057] Construction of the rotating mechanism

[0058] The design of the two contact surfaces of the Lulutong (a type of rotary connector) ensures that they only make contact at specific locations, reducing friction during rotation. This design avoids the friction and wear problems caused by excessively large contact surfaces in traditional structures, thus significantly extending its service life.

[0059] The micro-boob structure optimizes rotational smoothness and improves wear resistance. This structure allows for precise control of the contact area of ​​the rotating mechanism, reducing unnecessary friction and enhancing smoothness and durability during rotation.

[0060] Coating treatment

[0061] To improve durability, especially to reduce wear during long-term wear, a nanoscale coating can be applied to the rotating contact surface.

[0062] These coatings, such as diamond-like carbon (DLC) coatings or highly wear-resistant ceramic coatings, possess extremely high hardness and oxidation resistance, effectively preventing surface damage caused by friction. Furthermore, precious metal anti-oxidation coatings prevent discoloration, ensuring the jewelry always looks new.

[0063] Step 4: Seamless Welding and Surface Treatment

[0064] Seamless welding technology

[0065] Laser welding is used to weld multiple CNC-machined components together to form a complete main structure.

[0066] Laser welding offers precise energy control, allowing weld points to be perfectly concealed within the structure, avoiding visible weld marks that can occur in traditional welding and enhancing overall aesthetics and durability. The welded surface is flawless, with no noticeable gaps at the joint, providing a solid foundation for subsequent fine finishing. By precisely controlling energy output, weld points are less likely to be exposed, thus avoiding visual defects that can occur in traditional welding processes.

[0067] Polishing and finishing

[0068] Following seamless welding, the product surface undergoes ultra-fine grinding and polishing technology to achieve a mirror-like finish. This process not only enhances the product's visual appeal but also effectively reduces surface imperfections, improving its smoothness and tactile feel. Simultaneously, precision machining ensures the rotating mechanism's surface treatment reaches its optimal state.

[0069] Further optimize the surface treatment of the rotating mechanism to ensure smooth and frictionless rotation.

[0070] Step 5: Yunjin Gold Craftsmanship and Decoration

[0071] Application of Yunjin Gold Craft

[0072] The Yunjin gold craft uses techniques such as micro-carving, laser etching, or high-temperature sintering to carve exquisite three-dimensional relief or concave-convex texture designs onto the main structure, which not only increases the cultural value of the product but also greatly enhances its artistic sense, giving each product a unique aesthetic charm.

[0073] Patterns can include auspicious clouds, mythical beasts, the six-syllable mantra, or other traditional auspicious symbols to enhance the product's cultural value and artistic appeal.

[0074] Inlay technique

[0075] To further enhance the decorative appeal of a product, setting grooves can be pre-drilled into the surface, and gemstones, diamonds, or other precious metal ornaments can be set in appropriate positions using hand-setting or spot welding techniques. This process not only increases the product's luxurious feel but also enhances its market competitiveness, securing its place in the luxury market. Carefully selected gemstones or diamonds can elevate the value of jewelry, making it a highly sought-after piece in the luxury market.

[0076] Step Six: Product Assembly and Final Testing

[0077] Final assembly

[0078] After undergoing the aforementioned processing, the various components are precisely assembled. The assembly of the rotating mechanism and chain fixing structure, in particular, ensures smooth and secure operation of each component. During assembly, all parts are meticulously fitted together to ensure overall structural stability, perfect execution of the rotating function and chain connection. At this point, the overall product's stability and durability are fully guaranteed. Each product undergoes rigorous testing to ensure it can withstand various usage conditions in daily wear.

[0079] Quality Inspection

[0080] After final assembly, the product will undergo a series of rigorous quality tests:

[0081] Rotation test: Ensure that the rotation mechanism is smooth and without jamming, and meets the design requirements. Through rigorous rotation testing, ensure that the rotation function fully meets the design requirements and avoid unnecessary jamming or friction during use.

[0082] Wearing stability test: Check whether the copper coin structure can effectively fix the chain and ensure that it is stable and comfortable to wear. This test ensures that the product is stable when worn and that the chain will not become loose or unstable due to movement during the wearing process.

[0083] Visual inspection: Inspect the product's appearance to ensure there are no solder joints, scratches, or oxidation spots, meeting precision machining standards. Visual inspection is a crucial step in ensuring the product reaches a perfect level of craftsmanship, aiming to eliminate any defects that may affect its aesthetics and quality.

[0084] Implementation effect

[0085] By combining high-precision die casting with CNC precision machining, the product's hardness and durability have been significantly improved. In particular, the Vickers hardness of 80HV0.1 gives the product high wear resistance, making it suitable for prolonged wear. The optimized design of the rotating mechanism not only ensures smooth rotation but also avoids friction and wear issues. The precision machining of the internal copper coin structure effectively enhances wearing stability. Through the combination of seamless welding and Yun Jin gold craftsmanship, the product not only possesses a high-end appearance and exquisite craftsmanship but also rich cultural connotations, greatly enhancing its market competitiveness.

[0086] This embodiment fully leverages the advantages of combining modern precision manufacturing technology with traditional craftsmanship to provide users with high-quality, durable, and culturally valuable high-end jewelry.
