Description

Technical Field

[0001] This utility model relates to the field of jewelry processing equipment, specifically to a ring-shaped jewelry forming and cutting equipment. Background Technology

[0002] In the traditional craftsmanship of chain bracelets, the process is primarily done by hand. The specific steps are as follows: A straight silver bar is cut, and a cylindrical rod is used as a shaping tool. The silver bar is manually wound around the rod, achieving the initial shape of the silver bar through manual operation. Depending on the size of the bracelet's inset, excess silver is manually trimmed with pliers, completing the initial size adjustment.

[0003] However, the process of hand-winding silver bars is greatly affected by the operator's experience and technique, making it difficult to ensure that the size of each linked bracelet is completely consistent, resulting in poor product consistency. When hand-cutting silver bars, the cuts are often uneven, causing numerous problems in subsequent welding processes. For example, more solder needs to be accumulated to fill the gaps in the cuts, which not only affects the purity of the silver material but also increases the workload and leads to increased silver loss. Furthermore, the entire hand-processing relies heavily on manual labor; each step, from winding and cutting to post-processing, takes a considerable amount of time, making it unsuitable for large-scale production and resulting in low processing efficiency. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a ring jewelry forming and cutting device suitable for automated processing of ring jewelry such as chain bracelets.

[0010] Furthermore, the ring-shaped jewelry forming and cutting equipment also includes: The gripper mechanism is rotatably mounted on the frame, and one end of the winding component is detachably mounted on the gripper mechanism.

[0011] Furthermore, the gripper mechanism includes a three-jaw chuck.

[0012] Furthermore, the ring-shaped jewelry forming and cutting equipment also includes: The drive motor is mounted on the frame, and its output end is connected to the gripper mechanism, which is used to drive the winding material to rotate through the gripper mechanism.

[0013] Furthermore, the ring-shaped jewelry forming and cutting equipment also includes: Pressure plate: A pressure plate is used to apply pressure to a metal wire in the radial direction of the winding during cutting.

[0014] Furthermore, the ring-shaped jewelry forming and cutting equipment also includes: Stretch wrap is used to wrap around the outer periphery of metal wire during cutting.

[0015] Due to the implementation of the above technical solutions, this utility model has the following technical effects compared with the prior art: This utility model discloses a ring-shaped jewelry forming and cutting device.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature.

[0020] Combination Figures 1 to 5 As shown, the embodiments of this utility model are specifically described using a bracelet as an example of a ring-shaped piece of jewelry. In other embodiments, the ring-shaped jewelry forming and cutting equipment of this utility model is not only suitable for bracelet processing, but can also be widely used in the automated production of various ring-shaped or ring-like jewelry such as rings, earrings, necklace pendants, and decorative rings (such as bracelets and armbands).

[0021] The ring-shaped jewelry forming and cutting equipment includes a frame 1, a winding component 2, a slide rail 3, and a cutting component 4. The winding component 2 is rotatably mounted on the frame 1 and is used to wind metal wire 10 into a spiral shape. The length direction of the slide rail 3 is parallel to the axial direction of the winding component 2. The cutting component 4 is mounted on the slide rail 3 and can move along the length direction of the slide rail 3 to sequentially cut each loop of metal wire 10 on the winding component 2. The metal wire 10 can be silver wire or silver bar.

[0022] Specifically, the frame 1 serves as the basic support structure of the equipment, providing an installation platform for other components, ensuring the accurate relative positions of each component, and guaranteeing the overall stability of the equipment. The winding member 2 is mounted on the frame 1, and its function is to wind the metal wire 10 into a spiral shape. The winding member 2 can be designed as a cylindrical structure, driven by a drive device (such as a motor or hand crank) to rotate. Under the rotation of the winding member 2, the metal wire 10 is wound around its outer circumference, forming a spiral layer of metal wire. The slide rail 3 is parallel to the axial direction of the winding member 2 and is fixedly mounted on the frame 1. The slide rail 3 provides a moving track for the cutting member 4, ensuring the accurate movement direction of the cutting member 4. The cutting member 4 is mounted on the slide rail 3 and can move along the length of the slide rail 3.

[0023] For example, the cutting element 4 includes a cutting blade, which may be a saw blade or the like. It is driven by a motor or other device to move along the slide rail 3, thereby sequentially cutting each loop of metal wire 10 on the winding element 2. Optionally, the cutting element 4 also includes a protective cover over the cutting blade to prevent material from splashing outwards during the cutting process. Optionally, the cutting element 4 is mounted on the slide rail 3 via a cutting mounting base. A hinge structure and a telescopic structure connect the cutting mounting base and the slide rail 3, allowing the angle between the cutting mounting base and the slide rail 3 to be adjustable, thereby adjusting the cutting angle and cutting depth of the cutting blade.

[0024] The aforementioned ring-shaped jewelry forming and cutting equipment automates the entire process of metal wire 10 from winding to cutting, improving processing efficiency compared to manual processing. The precise rotation of the winding component 2 and the accurate movement of the cutting component 4 ensure consistent dimensions of the cut ring-shaped jewelry, thus improving product precision.

[0025] In some embodiments, the winding member 2 includes a first positioning part 21 and a second positioning part 22, which are respectively used to fix the two ends of the metal wire 10. The first positioning part 21 and the second positioning part 22 can be designed according to the characteristics of the metal wire 10 and the processing requirements. For example, for a thinner silver wire, the first positioning part 21 can be a through hole with a diameter slightly larger than the diameter of the silver wire. One end of the silver wire passes through the through hole and is fixed to prevent it from slipping off one end during the winding process. The second positioning part 22 can be a raised cylindrical structure. The other end of the silver wire is wound around the cylinder and fixed to ensure that both ends are stably fixed. In this way, the two ends of the metal wire 10 are effectively fixed by the first positioning part 21 and the second positioning part 22. During the rotation and winding process of the winding member 2, the wire will not slip or loosen, ensuring the stability of the winding process and providing a reliable foundation for subsequent cutting.

[0026] In one specific embodiment, the first positioning part 21 is a positioning hole extending radially along the winding member 2, and the second positioning part 22 is a positioning post protruding on the winding member 2. The first positioning part 21, as the positioning hole extending radially along the winding member 2, penetrates the side wall of the winding member 2. One end of the metal wire 10 can be inserted into the positioning hole for automatic positioning, or it can be fixed to the winding member 2 by knotting, welding, or other methods after passing through the positioning hole, ensuring that one end of the wire is firmly fixed. The second positioning part 22, as the positioning post protruding on the winding member 2, can be cylindrical, with its axis parallel to the axis of the winding member 2. The other end of the metal wire 10 is wound around the positioning post, and fixed through friction and winding force. The positioning hole and positioning post have a simple structure, are easy to process and implement, and can effectively fix both ends of the metal wire 10. In addition, the differentiated fixing method is adapted to the stress characteristics of the metal wire 10 during the winding process. One end is fixed through a hole to provide strong tensile resistance, while the other end is fixed by winding through a column to facilitate the guidance and winding of the wire, thereby improving the reliability and convenience of fixing.

[0027] In one specific embodiment, the winding element 2 is designed as a hollow tubular structure, the wall thickness of which can be designed according to the equipment strength and processing requirements. The hollow structure reduces the weight of the winding element 2, lowering the load on the drive unit. The reduced weight of the hollow tubular structure means less power is required when the drive motor rotates it, saving energy and improving equipment operating efficiency. The internal space can also be used to integrate other functional components, making the equipment structure more compact and facilitating overall layout and optimization.

[0028] Furthermore, a cutting clearance groove 20 is provided on the winding component 2. The cutting clearance groove 20 penetrates the tube wall of the winding component 2, and its length extension direction is parallel to the axis of the winding component 2. The width of the cutting clearance groove 20 is slightly larger than the thickness of the cutting component 4 to ensure that the cutting component 4 can pass smoothly. During the cutting process, as the cutting component 4 moves along the slide rail 3, it cuts the metal wire 10 wound on the winding component 2 through the cutting clearance groove 20. The cutting clearance groove 20 provides a dedicated cutting path for the cutting component 4, avoiding interference between the cutting component 4 and the tube wall of the winding component 2, and ensuring the smooth progress of the cutting process. This ensures that the cutting component 4 can accurately cut the metal wire 10, avoiding uneven cuts or equipment damage due to cutting position deviations, thus improving cutting accuracy and equipment reliability.

[0029] In some embodiments, the ring-shaped jewelry forming and cutting equipment further includes a gripper mechanism 5, which is rotatably mounted on the frame 1. One end of the winding member 2 is detachably mounted on the gripper mechanism 5. The gripper mechanism 5 can use common clamping devices such as a three-jaw chuck to clamp and fix one end of the winding member 2 through the three jaws of the chuck. When it is necessary to change to a winding member 2 of a different specification, the gripper can be loosened to quickly remove and install the new winding member 2. The gripper mechanism 5 enables the detachable installation of the winding member 2, making it convenient to change to a winding member 2 of the appropriate diameter according to different ring-shaped jewelry specifications, thus improving the versatility and flexibility of the equipment.

[0030] The gripper mechanism 5 specifically employs a three-jaw chuck, which features automatic centering. When the three jaws move simultaneously, they can quickly and accurately clamp one end of the winding component 2 in the center position, ensuring that the axis of the winding component 2 coincides with the output shaft axis of the drive motor, thus improving rotational accuracy. The automatic centering function of the three-jaw chuck ensures the installation accuracy of the winding component 2, preventing uneven force on the metal wire 10 during winding due to installation deviations, which could affect the dimensional accuracy of the product. The clamping and releasing operations are simple and quick, improving the operating efficiency of the equipment and reducing downtime for changing parts.

[0031] Optionally, a set screw is provided at the end of the winding member 2 away from the gripper mechanism 5. The set screw has a cone head, which can play an auxiliary role in fastening. After the gripper mechanism 5 clamps the winding member, the cone head of the set screw presses against the free end of the winding member 2 to prevent loosening caused by torque during the winding process. It is especially suitable for high-speed rotation or large-diameter winding member conditions.

[0032] The ring-shaped jewelry forming and cutting equipment also includes a drive motor 6, which is mounted on the frame 1. Its output end is connected to a gripper mechanism 5 via a coupling or other transmission components, driving the winding component 2 to rotate. The drive motor 6 can be a speed-regulating motor, adjusting its speed according to the material of the metal wire 10 and the required winding speed, thus achieving flexible control of the winding process. The drive motor 6 provides the power source for the rotation of the winding component 2, automating the winding process of the metal wire 10, replacing manual winding, and improving winding efficiency.

[0033] In one specific embodiment, the ring-shaped jewelry forming and cutting equipment further includes a pressure plate 7, which is used to apply pressure to the metal wire 10 along the radial direction of the winding member 2 when the cutting part 4 is being cut. The pressure plate 7 can be moved up and down by a driving device such as a cylinder. After the metal wire 10 is wound on the winding member 2, the cylinder drives the pressure plate 7 to rise, so that the pressure plate 7 presses on the metal wire 10. The pressure is maintained on the metal wire 10 through contact with the metal wire 10 by an elastic material such as rubber.

[0034] In another embodiment, the ring-shaped jewelry forming and cutting equipment further includes a stretch film 8, which is used to wrap around the outer periphery of the metal wire 10 during the cutting of the workpiece 4. The stretch film 8 can be manually wrapped or automatically wrapped around the metal wire 10 by a dedicated wrapping device. The wrapping device may include a rotating spool with the stretch film 8 wound on it. After the metal wire 10 is wrapped, the spool rotates, evenly wrapping the stretch film 8 around the outer periphery of the metal wire 10 to form a protective layer. During cutting, the stretch film 8 tightly wraps around the metal wire 10, further preventing the wire from unraveling, ensuring the stability of the metal wire 10 during the cutting process, and improving the cutting quality. The stretch film 8 can be easily removed after cutting without damaging the ring-shaped jewelry blank, and it is low in cost and convenient for mass production.

[0035] This invention effectively solves many problems associated with the manual processing of linked bracelets through structural design and the synergistic effect of its components in a ring-shaped jewelry forming and cutting equipment. It transforms traditional manual processing from inefficiency, low precision, and high waste to automated winding, fixing, and cutting processes, achieving consistent dimensions, even cuts, and high-efficiency processing. Different structural designs and functional settings work together to form a complete and reliable ring-shaped jewelry forming and cutting equipment, demonstrating significant technological advancement and practical application value. This ring-shaped jewelry forming and cutting equipment can cover most ring-shaped products in the jewelry industry, improving processing efficiency and quality, and is especially suitable for small and medium-sized jewelry factories.

Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
