[0025] The connecting portion 6222 is provided with a mounting platform at the rear of the mounting portion 6223, and the round core member 621 is provided above the mounting platform. The round core member 621 is installed on the mounting portion 6223 through a limiting column (not shown) extending forward and backward, and the round core member 621 can move forward and backward relative to the limiting column; the driving method of the forward and backward movement of the round core member 621 is not limited, and it can be conventional such as cylinder drive or the like. A notch groove 6224 is provided on the left side of the top of the mounting portion 6223. In this embodiment, the top surface of the mounting portion 6223 is flush with the top surface of the round core member 621. A round core shaft 6225 extending in the forward and backward direction is provided in the middle of the top surface of the round core member 621, and the front side end of the round core shaft 6225 extends out of the mounting portion 6223 to be used for forming the inner ring 201.

[0026] The core assembly 61 includes a core 611, a core mounting block 612 and a core drive (not shown). The mounting block 612 is provided with a limit hole 615 that runs through the front and back, and the cross-sectional shape of the limit hole 615 is consistent with the hollow hole 204 of the product. The core 611 is inserted into the limit hole 615, and its front end extends out of the mounting block 612. The rear end of the core 611 is installed on the core drive device, and the core drive device is used to drive the core 611 to move forward and backward. The core 611 is arranged in the shape of a long strip, and the shape of its end face is consistent with the shape and size of the hollow hole 204 of the product. A support base 614 is also provided on the rear side of the bottom of the core mounting block 612, and an overhead portion is formed on the front side of the bottom; so that when it is used in conjunction with the round core assembly 62, the space required is smaller. The bottom end surface of the limiting hole 615 extends forward from the side wall of the overhead portion to form a limiting block 616, the cross-section of the limiting block 616 is arc-shaped, and the top surface thereof is flush with the bottom surface of the limiting hole 615; the outer end surface of the limiting block 616 is used to limit the inner surface of the product.

[0027] The first side molding device 40 is arranged on one side of the feeding device 20. The first side molding device 40 includes a side driving device 41, a side push rod 42 and a side molding head 43. The side molding head 43 is arranged at the free end of the side push rod 42. The side push rod 42 is installed on the side driving device 41. The side driving device 41 drives the side push rod 42 to move forward and backward. The side molding head 43 is arranged in a direction corresponding to the core molding device 60. The side molding head 43 includes a main body 431 and a molding protrusion 432 arranged on the outer surface of the main body 431.

In this embodiment, the main body 431 of the side molding head 43 is thicker, and the molding protrusion 432 is thinner. Preferably, the inner surface of the main body 431 contacts the outer surface of the bottom plate 31. Since the product is extremely delicate, the double guidance of the side drive device 41 and the bottom plate 31 can avoid the problem of poor positioning accuracy after long-term use.

[0028] The structure of the second side forming device 50 is substantially the same as that of the first side forming device 40, and also includes a side driving device 51, a side push rod 52 and a side forming head 53. The difference lies in that the shape of the forming groove on the first side forming device 40 matches the bottom arc of the product outer edge 202 and the bottom arc of the inner ring 201, while the shape of the forming groove 54 on the second side forming device 50 is consistent with the bottom arc shape of the right outer edge 201.

[0029] The upper forming device 70 includes an upper core member 71, an upper limit block 72 and an upper driving device 73. The upper limit block 72 is installed on the outer side of the upper core member 71 and extends downward from the bottom end of the upper core member 71. The driving device 73 is used to drive the upper core member 71 to move up and down. An upper forming groove 711 is provided on the bottom surface of the upper core member 71. The shape of the groove bottom surface of the upper forming groove 711 is consistent with the shape of the upper surface of the outer edge 202 of the product. In addition, a storage table 80 is also provided on the frame 10 below the forming device 40. The storage table 80 can be used to place the finished product box to receive the blanked product.

[0030] When working, the feeding device 20 feeds the material toward the core forming device 60, feeds the gold wire horizontally to the top of the core 611, and then stops feeding. The front end of the gold wire is limited in the feeding device 20. The upper top core 71 of the upper forming device 70 moves downward rapidly, and the upper top core 71 and the core 611 clamp the gold wire. The front side end wall of the upper top core 71 is a vertical surface. In the process of rapid downward movement, a cutting action is formed with the outer end surface of the wire feeding nozzle 21, and the gold wire can be cut off. After cutting, the upper forming groove 711 of the gold wire cooperates with the core 611 to form the upper part of the outer edge 202, and the two ends of the gold wire segment extend downward. Then, the second side molding device 50 moves forward and upward, and bends the gold wire extending downward on the right side toward the left side; the round core piece 621 moves upward and cooperates with the bottom surface of the mold core 611 to press the gold wire to form the upper half of the inner ring 201, and the gold wire is then bent downward from the left side of the round core piece 621. Thereafter, the first side molding device 40 moves forward and upward, and bends the left and right ends of the gold wire toward the right side to form the lower left part of the outer edge 202 and the lower part of the inner ring 201. After molding, the mold core 611 and the round core shaft 6225 move backward, and the product is ejected and falls downward into the finished product box, thereby realizing the automated processing of the entire product.

[0031] In summary, the utility model is provided with a fully automatic feeding device 20 and a molding device 30, wherein the feeding device 20 performs fully automatic feeding to the molding device 30, and the molding device comprises a first side molding device 40, a second side molding device 50, a mold core molding device 60 and an upper molding device 70; the first side molding device 40, the second side molding device 50, the mold core molding device 60 and the upper molding device 70 cooperate with each other to process the gold wire into the desired product, with a high degree of automation, good product consistency and high precision. In addition, the overall design layout of the molding device 30 of the utility model is reasonable, does not need to occupy too much space, is highly practical, and has a strong promotion significance.
