Description

Technical Field

[0001] This utility model relates to the field of precious metal jewelry technology, and in particular to a device for winding precious metal jewelry. Background Technology

[0002] In the processing of precious metal jewelry (such as gold, silver, and platinum jewelry), it is often necessary to wind fine wires of precious metal material onto a specific base or mold to create complex parts or overall shapes of jewelry such as necklaces, bracelets, and earrings. This process is called wire winding.

[0003] Currently, the winding process for precious metal jewelry mainly relies on operators using hand tools and their own experience. While this method offers high flexibility, it is extremely inefficient, and product quality depends entirely on the operator's skill level. It is difficult to guarantee consistency in winding spacing, number of turns, and tension, resulting in a low product qualification rate. Furthermore, prolonged operation can easily lead to worker fatigue, further affecting product quality. In addition, some general-purpose winding machines exist on the market, which typically use a simple motor to drive the spindle for winding. However, most of these machines lack a precise wire guiding mechanism and cannot control the uniform distribution of the metal wire along the workpiece axis while winding. Manual intervention is still required for guidance, making them inconvenient for winding processing and thus failing to meet customer needs.

[0004] Therefore, those skilled in the art have provided a device for winding precious metal jewelry to solve the problems mentioned in the background art. Utility Model Content

A turntable 9 is fixedly connected to the top of the rotating shaft 8. A drive assembly 10 is arranged at the bottom of the inner cavity of the concave frame 1 and to the right of the rotating shaft 8. An electric cylinder 11 is fixedly installed on the left side of the top of the concave frame 1. The telescopic end of the electric cylinder 11 passes through the concave frame 1 and is rotatably connected to the pressure plate 12 through a bearing. A guide plate 13 is fixedly connected to the right side of the rectangular plate 3. A guide groove 14 is opened on the right side of the inner cavity of the concave frame 1 to cooperate with the guide plate 13. The outer surface of the guide plate 13 is slidably connected to the inner surface of the guide groove 14. A first anti-slip pad is provided on the top of the turntable 9, and the connection between the first anti-slip pad and the turntable 9 is bonded. A second anti-slip pad is fixedly connected to the bottom of the pressure plate 12, and the second anti-slip pad is circular. A rubber pad 15 is fixedly connected to the bottom of the concave frame 1. The rubber pad 15 is rectangular. An identification sticker 16 is provided on the right side of the concave frame 1, and the identification sticker 16 is bonded to the connection between the concave frame 1 and the concave frame 1.

[0033] In this embodiment: By setting up a concave frame 1, a rotating shaft 8, a turntable 9, a drive assembly 10, an electric cylinder 11, and a pressure plate 12, this utility model can press and limit the precious metal workpiece, and facilitate its rotation. By setting up a screw 2, a rectangular plate 3, a concave frame 4, a convex wire feeding rod 5, a wire guide nozzle 6, and a servo motor 7, the metal wire can be moved up and down and wound evenly. By setting up the above structure, it is convenient for winding processing, thereby meeting the needs of customers.

[0034] Example 2:

[0035] Reference Figure 2 and Figure 3 The drive assembly 10 includes a rotary motor 101. The bottom of the rotary motor 101 is fixedly connected to the connection point of the concave frame 1. A main helical gear 102 is fixedly connected to the output end of the rotary motor 101. A driven helical gear 103 is fixedly connected to the outer surface of the rotating shaft 8. The main helical gear 102 and the driven helical gear 103 mesh.

[0036] In this embodiment: By setting a rotary motor 101, a main helical gear 102 and a driven helical gear 103, the present invention can easily drive the rotating shaft 8 to rotate.

[0037] The implementation principle of this utility model is as follows: When in use, the operator connects the device to the mains power. Then, the operator places the precious metal jewelry base or mold mandrel to be wound on the first anti-slip pad on the top of the turntable 9. Next, the operator starts the electric cylinder 11, which causes the telescopic end of the electric cylinder 11 to drive the pressure plate 12 to move downward, so that the second anti-slip pad at the bottom of the pressure plate 12 is in close contact with the precious metal jewelry base or mold mandrel, thereby achieving the pressing and limiting of the workpiece.

[0038] Next, the operator places the wire roller with the precious metal wire wound on the convex feed rod 5. Then, the end of the precious metal wire is led out from the wire roller, passed through the wire guide nozzle 6, and fixed to one end of the workpiece. The operator then activates the external controller of the rotary motor 101 and servo motor 7, causing the output of the rotary motor 101 to drive the main helical gear 102 to rotate. The main helical gear 102 drives the driven helical gear 103 to rotate, which in turn drives the rotating shaft 8 to rotate. This causes the rotating shaft 8 to rotate the turntable 9, the workpiece, and the pressure plate 12 together, thus causing the workpiece to begin winding the precious metal wire around itself. Simultaneously, the output of the servo motor 7 drives the screw 2 on the rectangular plate 3. The inner surface thread rotates, causing the rectangular plate 3 to slide vertically along the concave frame 4. Simultaneously, the concave frame 4 drives the convex wire feeding rod 5 and the wire guide nozzle 6 to move vertically in sync, thus ensuring that the precious metal wire is tightly and evenly wound around the workpiece surface. After the winding is completed, the operator cuts the precious metal wire. Then, the operator restarts the external controller of the electric cylinder 11, causing the telescopic end of the electric cylinder 11 to move the pressure plate 12 upwards, causing the second anti-slip pad at the bottom of the pressure plate 12 to move away from the workpiece and release the limit, thus facilitating the operator to remove and unload the finished product from the winding process. This device is simple to operate and convenient for winding processing, thus meeting the needs of customers.

[0039] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
