Description

Technical Field

[0001] This utility model relates to the field of precious metal processing technology, and in particular to a weld-free one-piece necklace structure based on precious metal 3D printing. Background Technology

[0002] Jewelry such as necklaces that use clasps and links traditionally relies on welding techniques to connect the chain links, mainly including two methods: manual welding and automatic welding by chain-making machines.

[0003] Manual welding is further divided into solderless welding and solder welding. Solderless welding requires attaching and welding each link one by one, which is not only inefficient, but also highly dependent on the operator's skill in terms of finished product quality, which can easily lead to problems such as shape differences, structural deformation, and unsightly welds. Solder welding, on the other hand, may affect the purity of precious metals due to the mixing of solder, which can damage product quality and even lead to consumer disputes.

[0004] On the other hand, although the automatic welding technology of chain making machine is highly efficient, the shape of its chain links is pre-set by the chain making machine and the mold, which leads to serious limitations in product design. This technology is limited by the function of the equipment and the mold, resulting in a single style, lack of innovation, and difficulty in realizing other complex ring structure designs.

[0005] Therefore, in order to further improve the quality of existing necklace processing and expand the space for creative design and personalized customization of necklaces, we propose a weld-free one-piece necklace structure based on precious metal 3D printing. Utility Model Content

[0006] The purpose of this invention is to address the aforementioned shortcomings in the existing technology by proposing a weld-free, one-piece necklace structure based on precious metal 3D printing.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] Design a weld-free, one-piece necklace structure based on precious metal 3D printing. It is formed in a spiral structure on the platform of a precious metal 3D printing device and includes several chain links that are interlocked in sequence. A main support column is formed between the chain links and the platform, and a secondary support column is also formed inside the chain links.

[0009] The main support column includes a single-plant support column and an umbrella frame support column, wherein the umbrella frame support column has at least two support points below the chain link.

[0010] Furthermore, the chain segment has a ring-like structure;

[0011] The link is bent along its middle to form a fastening space, and the two ends of the link are attached to form a fastening part. The fastening parts of two adjacent links are fastened to the fastening space.

[0012] Furthermore, the gap between the fastening part and the fastening space is not less than 0.15mm.

[0013] Furthermore, each of the chain links has multiple individual support columns below it;

[0014] The plurality of the single-plant support columns are configured as cylinders with a diameter of not less than 0.4 mm and / or cones with an upper diameter of not less than 0.3 mm and a lower diameter of not less than 0.4 mm.

[0015] Furthermore, the umbrella frame support column includes a main rod and at least one support rod formed on the outer wall of the main rod. The main rod and the support rod are respectively connected below the chain link to form a support point.

[0016] Furthermore, the main rod is a cylinder with a diameter of not less than 0.4 mm, and the plurality of support rods are cylinders and / or tubular bodies with a diameter of not less than 0.2 mm.

[0017] Furthermore, the tilt angle of the support rod 222 is 45°-60° with the laser sintered layer.

[0018] Furthermore, the spacing between the single-plant support column and the umbrella frame support column is between 0.4 and 0.8 mm.

[0019] Furthermore, the secondary support column includes;

[0020] A front post formed inside the bent side of a single link and connecting the upper and lower parts of the single link;

[0021] And two rear columns respectively formed on the inner sides of the upper and lower parts of a single link;

[0022] The two rear columns are supported on the upper and lower walls of the fastening part of the chain link to which they are fastened, and the front column of a single chain link is located in front of the fastening part of the chain link to which it is fastened and is at least 0.15 mm apart.

[0023] Furthermore, both the front column and the rear column are configured as tubular bodies with a diameter of not less than 0.15 mm.

[0024] This invention proposes a weld-free, one-piece necklace structure based on precious metal 3D printing. The advantages are as follows: This invention uses precious metal 3D printing equipment to print the necklace structure in one step, achieving both the shape and functional movement of a necklace or similar clasp-like jewelry. Furthermore, the absence of solder ensures the purity of the metal. It also provides more space for innovative and personalized design of such products. The use of single-link support columns and umbrella-frame support columns effectively and stably supports each link above the equipment platform, ensuring the reliability of link forming and subsequent processing.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0032] Reference Figure 1-5 As one embodiment of this utility model, it discloses a weld-free one-piece necklace structure based on precious metal 3D printing. The necklace is formed in a spiral structure on the platform of the precious metal 3D equipment. By adopting a spiral structure arrangement, the working surface of the printing equipment can be fully utilized to achieve optimal space utilization.

[0033] Specifically, the necklace structure includes several chain links 1 that are linked together in sequence, a main support column 2 is formed between the chain links 1 and the platform, and a secondary support column 3 is also formed inside the chain links 1.

[0034] The main support column 2 includes a single plant support column 21 and an umbrella frame support column 22, wherein the umbrella frame support column 22 has at least two support points below the chain link 1.

[0035] In this invention, the necklace structure is printed in one step using a precious metal 3D printing device, which realizes the shape and function of a necklace or similar clasp-like jewelry. Since there is no solder, the metal color of the jewelry is guaranteed. At the same time, it provides more space for innovative and personalized design of such products. By adopting the support design of single support column 21 and umbrella frame support column 22, each link 1 can be stably supported above the equipment platform to ensure the reliability of the link 1 forming and subsequent processing.

[0036] In some embodiments, the chain link 1 in this invention has a ring structure;

[0037] The link 1 is bent along its middle to form a fastening space 11. The two ends of the link 1 are attached to form a fastening part 12. The fastening parts 12 of two adjacent links 1 are fastened to the fastening space 11.

[0038] In other words, the link 1 described in this utility model is designed with a central bending structure. After bending in the middle, the two ends are connected to fit together. The purpose of this design is to form a fastening space 11 in the middle of the link 1, and to form a fastening part 12 after the two ends are fitted together. When multiple links 1 are connected in sequence, they can be fastened in the fastening space 11 through the fastening part 12, thus completing the multi-connection ring-type connection.

[0039] It should be noted that the gap between the fastening part 12 and the fastening space 11 in this utility model is not less than 0.15mm. In this embodiment, a gap of 0.15mm is designed between the fastening part 12 and the fastening space 11 to enable a movable space to be formed between the two links 1, while avoiding adhesive connection during the 3D printing process.

[0040] Based on the above embodiments, in this utility model, there are multiple single-plant support columns 21 below each link 1. Preferably, in this utility model, two single-plant support columns 21 are arranged below each link 1, and the two single-plant support columns 21 are respectively arranged below the two bent parts of the link 1.

[0041] Optionally, in this utility model, the plurality of single-plant support columns 21 are configured as cylinders with a diameter of not less than 0.4 mm and / or cones with an upper diameter of not less than 0.3 mm and a lower diameter of not less than 0.4 mm.

[0042] In some embodiments, the umbrella frame support column 22 of the present invention includes a main rod 221 and at least one support rod 222 formed on the outer wall of the main rod 221. The main rod 221 and the support rod 222 are respectively connected to the lower part of the chain link 1 to form a support point.

[0043] In other words, by forming a support rod 222 on the outside of the main rod 221, the bottom of the chain link 1 is supported respectively, thus forming at least two support points. The design of this structure can further improve the stability of the support for the chain link 1.

[0044] In addition, such as Figure 5 As shown, the support rod 222 in this utility model can also be configured as multiple rods. Multiple support rods 222 can be circumferentially distributed on the outside of the main rod 221 to construct a multiple support point design structure. The support rod 222 is inclined on the outside of the main rod 221. Preferably, the inclination angle of the support rod 222 in this utility model is 45°-60° with the laser sintering layer.

[0045] In an optional embodiment, the main rod 221 of this utility model is a cylinder with a diameter of not less than 0.4 mm, and the plurality of support rods 222 are cylinders and / or tubular bodies with a diameter of not less than 0.2 mm. Their specific structures can be selected by those skilled in the art, and no further restrictions are imposed here.

[0046] It should be noted that the interval between the single plant support column 21 and the umbrella frame support column 22 in this embodiment of the present invention is between 0.4-0.8 mm.

[0047] Specifically, in this utility model, there are two individual plant support columns 21 and two umbrella frame support columns 22, and the two individual plant support columns 21 and the two umbrella frame support columns 22 are distributed in a matrix structure. The spacing between two adjacent support columns is configured in the interval range of 0.4-0.8mm, so as to ensure that each support column can stably support the chain link 1 on the platform of the printing equipment.

[0048] In some embodiments, the secondary support column 3 of this utility model includes;

[0049] A front post 31 is formed inside the bent side of a single link 1 and connects the upper and lower parts of the single link 1;

[0050] And two rear columns 32 respectively formed on the inner sides of the upper and lower parts of a single link 1;

[0051] The two rear columns 32 are supported on the upper and lower walls of the fastening part 12 of the link 1 that is fastened to them, and the front column 31 of a single link 1 is located on the front side of the fastening part 12 of the link 1 that is fastened to it and is at least 0.15 mm apart.

[0052] In other words, in this utility model, the connection between each link 1 is also set as a secondary support column 3 to improve the connection strength and ensure the molding stability during the 3D printing process. Specifically, in this utility model, the design of two rear columns 32 is used to achieve the connection support of the fastening part 12 of the link 1. That is, in this utility model, the front column 31 and the rear column 32 play the role of supporting the printing and molding at the position, ensuring that the upper link at the position can be formed.

[0053] In an optional embodiment, both the front column 31 and the rear column 32 of this invention are tubular bodies with a diameter of not less than 0.15 mm. In addition, the front column 31 and the rear column 32 of this invention can be configured as cylindrical or arc-shaped structures, and their specific shapes can be selected by those skilled in the art, without limitation.

[0054] During specific processing;

[0055] First, a three-dimensional auxiliary design for jewelry is adopted to integrate the product shape and set the connection relationship between the chain links or clasps. Before the precious metal 3D printing is formed, the feasibility and wearability of simulating the necklace or clasp structure jewelry are realized. The necklace is arranged in a spiral shape to make full use of the printing equipment's working surface.

[0056] Using precious metal 3D printing equipment, the designed three-dimensional model of the necklace is printed into a physical object. A special tool is used to remove the workpiece from the operating platform, and a necklace is formed as a whole.

[0057] After the main support column 2 and the secondary support column 3 are removed, the workpiece is processed by subsequent processes such as mold making, polishing, and electroplating.
