Description

Technical Field

[0001] The invention relates to the technical field of silver ornament production, in particular to a process for producing one-piece engraved and woven silver ornaments. Background Art

[0002] The traditional silver jewelry making process usually requires multiple steps to complete, including pre-treatment, molding, engraving, weaving and post-processing. These steps are often carried out separately, which is not only inefficient but also difficult to ensure the consistency and precision of each step.

[0003] The existing process methods have many defects in quality control and detail processing, especially in the process of fine engraving and weaving, which are prone to problems such as inadequate details and weak structure. In addition, the existing technology has deficiencies in the following aspects:

[0004] 1. In traditional processes, the purity and treatment methods of silver materials are not refined enough, resulting in unstable quality of finished products. The cleaning and annealing of silver materials are not thorough enough, which affects the effect of subsequent processes. The existing smelting technology has deficiencies in temperature control and impurity removal, which makes it difficult to completely remove impurities in silver materials, affecting the purity and beauty of silver jewelry;

[0005] 2. In the traditional casting process, the drying and cooling process of the mold is not scientific enough, which easily leads to bubbles and cracks in the finished product, affecting the quality of the finished product. The control of temperature and pressure during the forging process is not precise enough, resulting in unstable shape and strength of the silver parts;

[0006] 3. In the engraving process, the tools and methods for preliminary engraving and detailed engraving are relatively primitive, and it is difficult to achieve high-precision patterns and texture effects;

[0007] 4. During the weaving process, the cleaning and polishing of the silver parts were not detailed enough, which affected the weaving effect and the glossiness of the finished product.

[0008] 5. In the traditional silver jewelry manufacturing process, the engraved part and the woven part are usually made separately and then connected by welding. This method has the following problems: (1) The welding position is prone to form a weak link, affecting the overall strength and service life of the product; (2) The texture and pattern of the welding point are difficult to achieve a natural transition, affecting the overall aesthetics; (3) The welding process increases the production steps, reduces production efficiency, and increases product costs; (4) The welding position is prone to oxidation and discoloration, affecting the overall quality of the product.

[0009] As consumers' requirements for the quality and craftsmanship of silver jewelry increase, how to improve the efficiency and quality of silver jewelry production has become an urgent problem to be solved in the industry. In view of this, an integrated engraving and weaving silver jewelry production process is designed. Summary of the invention

[0111] S15. Quality Inspection

[0112] High-precision testing equipment is used to conduct comprehensive testing on the final silver jewelry.

[0113] Specifically, the present invention provides an integrated engraved and woven silver jewelry production process, which improves the efficiency and quality of silver jewelry production through systematic step integration.

[0115] Cleaning (S11): using an ultrasonic cleaning machine for cleaning, the cleaning time is 5 to 10 minutes.

[0116] Annealing treatment (S12): Annealing treatment is performed in an annealing furnace, the annealing temperature is controlled at 600° C. to 700° C., and the annealing time is 20 to 30 minutes.

[0117] Specifically, ultrasonic cleaning effectively removes impurities on the surface of silver through high-frequency vibration, making it less likely for impurities to be included in the silver during the smelting and forging process. It also selects high-purity silver to improve the purity of the final silver jewelry. Annealing treatment controls the annealing temperature and time to make the internal structure of the silver more uniform, improves its ductility and plasticity, and provides a good physical property foundation for subsequent processing, thereby improving the final quality of the silver jewelry and reducing the occurrence of defects.

[0118] The silver material smelting step (S2) specifically includes:

[0119] Melting (S21): The silver material is melted in a high temperature electric arc furnace, the melting temperature is controlled at 1000° C. to 1200° C., and the melting time is 15 to 20 minutes.

[0120] Impurity removal (S22): During the smelting process, an appropriate amount of borax is added to remove impurities.

[0121] Specifically, a high-temperature electric arc furnace is used to melt silver to ensure its full melting and uniformity. An appropriate amount of borax is added to remove impurities to make the molten silver purer. The melting temperature is controlled between 1000°C and 1200°C to ensure that the silver can be completely melted without overheating and decomposition. The melting time is controlled to ensure that the silver is fully melted without excessively extending the melting time, avoiding energy waste and material degradation. The addition of borax during the impurity removal process further removes oxides and other impurities in the silver, thereby improving the purity of the silver.

[0122] The casting step (S3) specifically includes:

[0125] Specifically, the molding quality of the silver parts is ensured by strictly controlling the casting process and cooling time. The molten silver material is injected into a dry graphite mold to avoid interference from moisture and impurities, ensuring the molding accuracy and surface quality of the silver parts. The silver parts are cooled at room temperature for 10 to 15 minutes to gradually cool down the silver parts, reduce the generation of internal stress, and avoid deformation and cracks of the silver parts.

[0126] The forging step (S4) specifically includes:

[0127] Forging heating (S41): The silver piece is heated to 800°C to 900°C in a heating furnace.

[0128] Forging operation (S42): Forging is performed using a hydraulic forging machine with a pressure of 30 to 50 tons and a forging time of 5 to 10 minutes.

[0129] Specifically, the physical properties of the silver parts are further improved by controlling the forging heating and forging pressure. The forging heating in the heating furnace allows the silver parts to be fully heated between 800°C and 900°C, which improves the ductility and plasticity of the silver parts. A hydraulic forging machine is used for forging. By controlling the pressure (30 to 50 tons) and adjusting the forging time (5 to 10 minutes), the density and hardness of the silver parts are improved, the internal stress is reduced, and the durability and stability of the silver parts are enhanced.

[0130] The tableting step (S5) specifically includes:

[0131] Press heating (S51): preheating the silver piece to 400°C to 500°C to ensure that the silver material has good ductility.

[0132] Tablet pressing operation (S52): a tablet press is used for progressive pressing, with the pressing force gradually increasing from 20 tons to 35 tons, so that the silver sheet forms a thickness gradient structure, ensuring that the thickness at the engraved part is greater than 0.6 mm and the thickness at the woven part is less than 0.3 mm.

[0133] Specifically, in the sheeting step (S5), the present application adopts an innovative integrated processing technology, and through the sheeting process, the silver piece is formed into a thickness gradient structure, and the natural transition between the woven part and the engraved part is achieved through precision cutting. Compared with the traditional welding process, the thickness gradient structure formed by the sheeting process ensures the perfect combination of the engraved part and the woven part, and avoids the structural weakness problem in the traditional welding process; the precision cutting technology is used to achieve the natural transition between the woven pattern and the engraved pattern, thereby improving the overall beauty of the product; the integrated processing technology reduces additional processes such as welding, improves production efficiency, and reduces production costs; avoids oxidation discoloration problems at welding points, and ensures the overall quality of the product; by controlling the accuracy of the pressing thickness and cutting width, the engraved part and the woven part can maintain their respective process characteristics while achieving seamless connection, thereby improving the artistic value and practicality of the product.

[0134] The preliminary engraving step (S6) specifically includes:

[0135] Pattern design (S61): Draw basic patterns and textures on the surface of the silver piece.

[0136] Electric chiseling (S62): Use an electric chiseling tool to perform preliminary chiseling according to the design.

[0137] Specifically, drawing basic patterns and textures on the surface of the silver pieces provides a clear reference for subsequent engraving, avoiding blind processing.

[0140] Re-inspection (S72): The refined silver piece is inspected to ensure that the pattern and texture are clear and accurate.

[0141] Specifically, the use of fine chisels and magnifying glasses for engraving allows every detail to be fully displayed, improving the fineness and quality of the silver jewelry. Inspection then ensures that there are no omissions or errors in the refined silver pieces, ensuring the accuracy and beauty of the final effect.

[0142] The fine engraving step (S8) specifically includes:

[0143] Fine inspection (S81): Use a high-power magnifying glass to inspect the details of patterns and textures.

[0147] Ultrasonic cleaning (S91): The engraved silver piece is cleaned using an ultrasonic cleaning machine for 5 to 10 minutes.

[0148] Preliminary polishing (S92): Use a polishing machine to perform preliminary polishing to make the surface of the silver piece smooth, and the polishing time is 5 to 10 minutes.

[0149] Specifically, ultrasonic cleaning is used to effectively remove impurities and dirt remaining in the engraving process, making the silver parts less susceptible to contamination during the weaving process. The initial polishing makes the surface of the silver parts smoother, providing a good foundation for subsequent weaving and forming, ensuring the surface quality and weaving effect of the silver jewelry, and improving the quality and aesthetics of the final product.

The weaving molding gives the silver jewelry a unique structural beauty and artistic value, thereby improving the overall quality of the silver jewelry.

[0151] Specifically, in the alum boiling step (S12), oxides and impurities on the surface of the silver ornaments are removed by alum boiling treatment, thereby improving the brightness and aesthetics of the silver ornaments.

[0152] Specifically, in the polishing step (S13), the silver ornaments after being boiled with alum are polished using a fine-bristled brush and a special polishing paste to ensure the smoothness and brightness of the surface of the silver ornaments.

[0153] Specifically, in the washing and drying step (S14), residual alum and impurities are removed through the combination of washing and drying, thereby improving the cleanliness and quality of the silver jewelry.
