[0026] In order to make the objectives, technical solutions and advantages of the embodiments of the present disclosure more clear, the embodiments of the present disclosure are further described in detail below in combination with the embodiments and drawings. The schematic implementation methods of the embodiments of the present disclosure and their descriptions are only used to explain the embodiments of the present disclosure and are not intended to limit the embodiments of the present disclosure.

[0027] First, refer to Figure 1 , describes a bending device for silver jewelry processing of the present application. Figure 1 As shown, a bending device for silver jewelry processing according to the present application includes a base 1, a drive motor 2, a first rotating shaft 3, a bending roller 4, a shock-absorbing spring device 5, and a workbench 6 for adjusting the preload of the shock-absorbing spring device 5. The drive motor 2 is mounted on the base 1 to drive the first rotating shaft 3 to rotate. The bending roller 4 is fixed to the first rotating shaft 3 and is designed to contact the silver jewelry to accurately bend it. The shock-absorbing spring device 5 is disposed between the first rotating shaft 3 and the base 1. Specifically, the shock-absorbing spring device 5 is rotationally connected to the first rotating shaft 3, effectively improving the stability and bending accuracy of the device during operation by reducing vibration caused by the operation of the drive motor 2. The workbench 6 is equipped with an adjustment mechanism, which allows the tightening state of the shock-absorbing spring device 5 to be manually or automatically adjusted as needed to adapt to different processing conditions. Specifically, for example, the workbench can be split, and the shock-absorbing spring device 5 is configured to apply pressure to its periphery through the split workbench 6, thereby allowing the tightening state of the shock-absorbing spring device 5 to be changed. In this case, the workbench 6 is set on the guide rail on the base 1, and the split workbench 6 clamps the outer periphery of the shock-absorbing spring device 5, and then the shock-absorbing spring device 5 is given different clamping states by adjusting the distance between the split workbench 6.

[0028] In the application embodiment of the present application, when the device is started, the drive motor 2 starts working to drive the first rotating shaft 3 and the bending roller 4 mounted thereon to start rotating; during this process, since the shock-absorbing spring device 5 is cleverly placed between the combined system of the drive motor 2 and the first rotating shaft 3 and the base 1, it can provide a buffer when the equipment vibrates, thereby reducing or isolating the vibration energy transmitted by the motor rotation; and the workbench 6 is equipped with a special adjustment mechanism, through which the shock-absorbing spring device 5 connected between the first rotating shaft 3 and the base 1 can be adjusted accordingly according to the actual bending situation, so as to ensure that the surface of the silver jewelry will not be scratched, twisted or other defects caused by deviations caused by vibration during the entire bending process. This innovative structure not only greatly optimizes the quality of the finished silver jewelry, but also effectively improves the operating experience and efficiency level of the production line.

[0029] In one embodiment, Figure 2 As shown, the drive motor 2 of a silver jewelry bending device according to the present application is equipped with a sound-insulating and noise-reducing housing 21 specifically designed to reduce noise and isolate vibrations. This design effectively suppresses the sound produced during motor operation, preventing excessive noise from being heard by the outside world. Made of a composite material with excellent sound absorption and balanced stiffness, the sound-insulating and noise-reducing housing 21 not only absorbs some of the sound wave energy transmitted by the motor itself and its driving components during operation, but also reduces any interference from the external environment with the motor's operating stability.

[0030] To further prevent motor vibration from destabilizing the entire structure of the press brake and ensure the machining accuracy and service life of the entire system, this device mounts the drive motor 2 on the equipment base 1 via a flexible connection. This flexible connection is typically made of rubber or other similar materials with excellent elasticity and cushioning properties. This not only blocks ground vibrations transmitted to the motor, but also reduces vibrations that propagate to other components of the equipment during operation due to factors such as unbalanced rotor rotation. This approach not only enhances the system's dynamic performance but also optimizes the operator's working environment.

[0031] In one embodiment, a bending device for silver jewelry processing employs a specialized rubber material to wrap a bending roller 4. Specifically, the exterior of the bending roller 4 is encased in a rubber sleeve 41. This specialized rubber sleeve 41 not only provides excellent cushioning during the bending process, effectively mitigating the rebound of the workpiece after application of force, thereby improving machining stability and control accuracy, but also exhibits excellent wear resistance and resilience, ensuring the device's long-term operation under high-intensity operating conditions and reducing scratches or other surface damage caused by direct metal contact. This design is crucial for ensuring the precise processing and surface quality of silver jewelry.

[0032] For example, a rubber material with a specific formula can be used to make a sleeve of appropriate thickness and size, which can then be heat-shrunk or tightly fixed to the surface of the bending roller 4 by other means. When selecting the rubber material, it is necessary to consider the material's elastic modulus, friction coefficient, and wear resistance under long-term use, so as to ensure that it meets both the buffering requirements and the durability for long-term use. In addition, the thermal conductivity of the rubber material and its stability to the chemical reaction of silverware can also be considered to prevent potential situations that affect product quality. In this way, the rubber sleeve 41 can be used to improve the ergonomics and processing accuracy of the entire processing system.

[0033] In one embodiment, a bending device for silver jewelry processing of the present application is provided with multiple anti-slip support feet 7 below the base 1, which not only provide stable support but also have the function of height adjustment. Each anti-slip support foot 7 is built into a leveling nut 8. During use, the height of each anti-slip support foot 7 can be independently adjusted by rotating the leveling nut 8, so that the base 1 can adapt to work surfaces of different flatness and achieve the effect of horizontal placement in complex use environments. This independently adjustable support design effectively improves the overall stability and accuracy of the equipment, reduces the resonance effect caused by the instability of the equipment, and further improves the accuracy and safety of the equipment during processing.

[0034] To achieve this, the leveling nut 8 typically features an external thread structure, with matching internal threads located inside the non-slip support legs 7. To adjust the height, the user simply uses an appropriate tool, such as a hexagonal wrench, or manually rotates the leveling nut 8, located at the outer end of the support legs, to move it up or down until all legs are properly positioned and the entire device is in ideal working condition. This approach is both simple and practical, helping to improve work efficiency.

[0035] In one embodiment, Figure 4 As shown, in the present application, a silver jewelry bending device is mounted on a specially designed vibration-damping structure to reduce the impact of lateral vibration caused by motor operation during the bending process on the overall stability and accuracy of the device. Specifically, buffer pads 9 are arranged on both sides of the base 1 of the drive motor 2. These buffer pads 9 are typically selected based on the damping properties of materials science and can effectively reduce mechanical vibration from the side, thereby improving the stability of the device and extending its service life.

[0036] To achieve these characteristics, a buffer gasket 9 made of a highly shock-absorbing composite material or a specific rubber can be selected to complement the motor base. These materials, due to their unique characteristics of high internal damping and rapid deformation recovery, absorb significant amounts of kinetic energy when subjected to external compression, converting it into heat and dissipating it. This effectively suppresses lateral vibration and ensures motor stability throughout the entire silver jewelry bending process. Furthermore, selecting the appropriate thickness and hardness of the buffer gasket 9 is crucial for optimizing system performance.

[0037] In one embodiment, a bending device for silver jewelry processing according to the present application incorporates a rubber ring gasket 10 within the inner bore of the bending roller 4. This rubber ring gasket 10 provides a flexible connection during device operation, significantly reducing shock. This reduces the potential adverse effects of external dynamic shock on the silver jewelry being bent, effectively preventing unnecessary deformation, damage, and other potential defects during processing, and improving the quality of the silver jewelry.

[0038] To achieve the aforementioned purpose of providing the rubber ring gasket 10 within the bending roller 4, a rubber ring made of a polymer material with high strength and excellent elasticity can be selected as a shock-absorbing component during the specific design, and tightly installed at the junction between the bending roller 4 and the drive mechanism. The inner diameter of the rubber ring should be slightly smaller than the diameter of the connecting piece of the drive mechanism, or it can be compressed and deformed to fit the bending roller 4 through appropriate design. This can form a stable and flexible contact surface, ensuring effective absorption of vibration energy while maintaining good force transmission performance.

[0039] In one embodiment, Figure 3 As shown, to effectively absorb and mitigate the adverse effects of mechanical vibration on overall system performance, the shock-absorbing spring device 5 utilizes a combination of multiple concentrically arranged coiled shock-absorbing springs 11. These concentrically arranged coiled shock-absorbing springs can adjust their spring stiffness coefficients according to varying vibration frequency requirements. This allows for more precise adaptation to or offsetting of vibrations on the workbench 6, thereby improving dynamic balancing during the silver jewelry processing process and significantly enhancing the stability and operational safety of the equipment.

[0040] For example, in a specific technical implementation plan, a multi-stage composite shock absorption system can be formed by selecting multiple shock-absorbing springs made of materials with good elastic recovery properties and with different diameters and numbers of turns, and installing them in parallel or in series; by calculating and analyzing the vibration spectrum characteristics of the workbench 6 under different working conditions, the corresponding spring parameter combination is selected to ensure that when the machine is started, it can automatically enter the optimal shock absorption state, effectively suppressing various potential risks caused by vibration, such as excessive noise and deterioration of workpiece quality, and at the same time it is also beneficial to improve the service life of the overall mechanical equipment.

[0041] In one embodiment, a bending device for silver jewelry processing of the present application is provided with sound insulation and shock absorption pads 12 on the four edges of the base 1. In order to achieve effective sound insulation and shockproof effects, the sound insulation and shock absorption pad uses polyurethane foam material as the outer edge protection layer. This layer of material can effectively absorb sound energy and convert it into heat energy due to its unique porous structure, thereby preventing the noise generated by the high-speed movement of the device during the processing from propagating outward. At the same time, the polyurethane foam material also has excellent shock absorption performance, which can buffer the effects of external forces during the operation of the equipment, reduce the impact of vibration on the system, and ensure that the equipment maintains good working condition and structural integrity even under the impact of external forces through its excellent mechanical strength. This design not only improves the quietness of the operating environment of the equipment, but also enhances the safety and reliability of the entire device when operating in harsh environments, reduces maintenance costs, and extends the service life of mechanical equipment.

[0042] In terms of specific technical implementation, the sound insulation and shock absorption pads can be installed on the edge of the base 1 by gluing or mechanical fixing. The specific density and thickness of the polyurethane foam material can be optimized and customized according to the expected sound absorption and shock absorption performance. In actual production, these shock absorption pad components can be manufactured through a pre-forming process to make them fit the shape of the base 1 tightly and achieve ideal functional performance. In addition, to improve the reliability of bonding or simplify the installation process, the design can also consider adding auxiliary fixing methods such as buckles and clamping mechanisms to ensure that the sound insulation and shock resistance effects will not be weakened during long-term use.

[0043] During actual operation, when this device is used, the silver jewelry is first placed under the bending roller 4 in preparation for the bending process. Subsequently, the drive motor 2 is started to drive the first rotating shaft 3, causing the bending roller 4 fixed thereto to rotate and contact the silver jewelry to apply force, causing it to bend and deform, completing the basic bending operation of the silver jewelry. At the same time, to reduce the vibration generated by the operation of the drive motor 2 throughout the entire processing process, a shock-absorbing spring device 5 is specially provided on the bending system. During the specific operation process, the pre-load of each shock-absorbing spring is finely adjusted and corrected through an adjustment structure pre-installed on the workbench 6 at the bottom of the device to ensure that it can effectively mitigate the negative impact of vibration during high-speed operation of the motor and further stabilize the device, thereby improving the overall operational stability of the device and the accuracy of the bending process, ensuring that the silver jewelry obtained after each processing is not only precisely shaped but also has a smooth and delicate outer surface, without any scratches or damage caused by vibration. The purpose of this design is to effectively overcome the problems of low finished product qualification rate and unstable product quality caused by vibration during device operation in traditional technical means. The design concept of the entire device fully takes into account practicality and precision control, which not only makes it have high production efficiency but also ensures the high quality results of silver jewelry in each process.

[0044] The above are only specific embodiments of the present application, but the scope of protection of the present application is not limited thereto. Any person skilled in the art can easily conceive of various modifications or substitutions within the technical scope disclosed in this application, and such modifications or substitutions should be included in the scope of protection of the present application. Therefore, the scope of protection of the present application should be based on the scope of protection of the claims.
