[0022] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0023] like Figures 2 to 7As shown, it is a first embodiment of a gold ornament multi-angle hollow filigree automatic forming machine 100 of the utility model, comprising a frame 10 and a feeding assembly 20, a clamping assembly 30, a bending assembly 40, a forming assembly 50a, a carrying platform 60 and an automatic control system (not shown in the figure) installed on the frame 10, wherein the feeding assembly 20 and the clamping assembly 30 are both installed on the front side of the frame 10 and are arranged on the same horizontal line in the left and right directions, the bending assembly 40 is installed on the front side of the frame 10 and is located below the clamping assembly 30, the forming assembly 50a is installed on the front side of the frame 10 and surrounds the clamping assembly 30, the carrying platform 60 is installed on the front side of the frame 10 and is located below the bending assembly 40, and the automatic control system is installed inside the frame 10 and is connected to each component by signal. A material unloading tray (not shown in the figure) is also provided on the carrying platform 60, and the material unloading tray is located below the clamping assembly 30. The unloading tray can receive the polygonal filaments 70a that fall off the clamping assembly 30 after being formed.

[0024] The feeding assembly 20 includes a feeding frame 21 , a feeding clamp 22 , a clamping cylinder 23 , a feeding cylinder 24 , a fixing frame 25 , a threading rod 26 and a fixing cylinder 27 . The loading rack 21 is fixedly mounted on the frame 10 and is located on the left side of the clamping assembly 30. A feeding slide rail 211 is also provided on the loading rack 21. The feeding clamp 22 is mounted on the feeding slide rail 211 in a clamping manner. The clamping cylinder 23 is mounted on the feeding clamp 22 and can drive the feeding clamp 22 to open and close. The feeding cylinder 24 is mounted on the loading rack 21 and can drive the feeding clamp 22 to slide left and right along the feeding slide rail 211. The fixed frame 25 is fixedly mounted on the loading rack 21 and is located on the right side of the feeding clamp 22. The threading rod 26 is penetrated in the fixed frame 25 along the left and right direction. The fixed cylinder 27 is mounted on the upper end of the fixed frame 25 and can drive the threading rod 26 to open and close.

[0025] When loading, firstly, the gold thread is passed through the feeding clamp 22 along the loading frame 21, then the clamping cylinder 23 is started to clamp the gold thread, and then the feeding clamp 22 is pushed to the right by the feeding cylinder 24, and the clamped gold thread will also move to the right and pass through the threading rod 26 on the fixed frame 25 until it is fed into the clamping assembly 30. When the gold thread enters the clamping assembly 30 and the loading operation is completed, the fixed cylinder 27 will start to press down to make the threading rod 26 clamp the gold thread and fix it. At the same time, the cutter between the loading assembly 20 and the clamping assembly 30 will also cut the gold thread, so that the gold thread on the clamping assembly 30 is exactly the same as the length required for forming the polygonal filament 70a. The clamping cylinder 23 will rise again, and after the feeding clamp 22 releases the gold thread, it will be driven by the feeding cylinder 24 to move left to complete the reset.

[0026] The clamping assembly 30 includes a mold frame 31, a mold base 32, a mold pin 33, a telescopic cylinder 34, a push plate 35 and a clamping cylinder 36. The mold frame 31 is fixedly mounted on the frame 10. The mold base 32 is mounted on the mold frame 31 in a snap-fit ​​manner. The mold base 32 is provided with a mold pin through hole (not shown) that runs through the front and back. The mold pin 33 is inserted into the mold pin through hole. The cross section of the mold pin 33 is designed to be polygonal. Specifically, in this embodiment, the cross section of the mold pin 33 is designed to be triangular. The telescopic cylinder 34 is mounted in the frame 10 and is connected to the tail end of the mold pin 33 by power. The push plate 35 is mounted on the mold frame 31 in a snap-fit ​​manner and is located above the mold pin 33. The lower end of the push plate 35 is also provided with an arc-shaped notch 351. The clamping cylinder 36 is mounted on the mold frame 31 and is connected to the upper end of the push plate 35 by power.

[0027] The gold thread fed into the clamping assembly 30 is located between the mold pin 33 and the push plate 35. Once the clamping cylinder 36 is activated to push the push plate 35 downward, the gold thread will be clamped between the mold pin 33 and the push plate 35. Since the polygonal cross-section design of the mold pin 33 matches the arc-shaped notch 351 at the lower end of the push plate 35, the clamped gold thread will be bent into an "n" shape, thereby achieving the preliminary shaping of the polygonal filament 70.

[0028] The bending assembly 40 includes a lifting push plate 41 and a lifting cylinder 42. The lifting push plate 41 is mounted on the mold frame 31 and is located below the mold pin 33. The upper end of the lifting push plate 41 is also provided with a bending notch 411 corresponding to the bottom of the mold pin 33. The lifting cylinder 42 is installed on the frame 10 and is connected to the lower end of the lifting push plate 41 by power.

[0029] Although the golden wire used to form the polygonal filament 70a is initially shaped under the clamping and bending of the clamping assembly 30, its two ends are still in a relatively vertical structure, which is not convenient for the subsequent stamping and forming of the forming assembly 50a. Therefore, the lifting cylinder 42 can drive the lifting push plate 41 to punch upward, and after punching through the bending notch 411 at the upper end of the lifting push plate 41, the vertical structures at both ends of the golden wire will bend inward to form an arc structure, thereby facilitating the further stamping and forming of the forming assembly 50.

[0030] The molding assembly 50a includes a first molding push plate 51, a first molding cylinder 52, a second molding push plate 53 and a second molding cylinder 54. The first molding push plate 51 is mounted on the lower left side of the mold frame 31, the first molding push plate 51 is tilted, and a first molding notch 511 is provided at its upper end and points to the mold needle 33. The first molding cylinder 52 is fixedly mounted on the frame 10 and is connected to the first molding push plate 51 by power. The second molding push plate 53 is mounted on the lower right side of the mold frame 31, the second molding push plate 53 is tilted, and a second molding notch 531 is provided at its upper end and points to the mold needle 33. The second molding cylinder 54 is fixedly mounted on the mold frame 31 and is connected to the second molding push plate 53 by power.

[0031] During the final forming, it is only necessary to start the first forming cylinder 52 and the second forming cylinder 54 at the same time. The two groups of cylinders push the first forming push plate 51 and the second forming push plate 53 upward along the lower left side and the lower right side respectively. The forming notch on the upper end of the forming push plate can further stamp out the two ends of the inward-bent golden wire, and finally process the complete polygonal filament 70a.

[0032] like Figures 8 to 9 As shown, it is the second embodiment of a gold ornament multi-angle hollow filigree automatic forming machine 100 of the utility model. The structure of this embodiment is basically the same as the first embodiment, and the difference is that: the cross-section of the mold needle 33 is designed in a quadrangular shape, and the clamping assembly 30 also includes a limit baffle (not shown in the figure), which is fixedly installed on the front side of the lower end of the push plate 35. The limit baffle is provided with an auxiliary forming through hole (not shown) that runs through the front and back, and the auxiliary forming through hole is designed in a semicircular shape. The forming assembly 50b also includes an auxiliary forming frame 55, a third forming mold rod 56 and a third forming cylinder 57. The auxiliary forming frame 55 is fixedly installed on the mold frame 31 and is located in front of the mold needle 33. The third forming mold rod 56 is clamped and installed on the auxiliary forming frame 55 and can be inserted into the auxiliary forming through hole. The third forming cylinder 57 is fixedly installed on the auxiliary forming frame 55 and is connected to the third forming mold rod 56 in power.

[0033] Different from the final forming of the first embodiment, in the second embodiment, while the first forming cylinder 52 and the second forming cylinder 54 are started to push the first forming push plate 51 and the second forming push plate 53, the third forming cylinder 57 on the auxiliary forming frame 55 is also started at the same time, pushing the third forming mold rod 56 through the auxiliary forming through hole on the limit baffle until it is combined with the first forming notch 511 and the second forming notch 531 to extrude the two ends of the golden wire, so that it is finally processed into a complete polygonal filament 70b.

[0034] In summary, the beneficial effect of the utility model of the automatic forming machine 100 for gold ornaments with polygonal hollow filigree is that: by designing components for automated operation, the gold wire is fed, clamped, bent and finally formed into polygonal filigree, which greatly improves the production efficiency compared with the conventional manual processing method. At the same time, the automatic forming method is more stable and reliable, making the quality of the formed filigree more uniform. In addition, the overall structural layout of the utility model is reasonable, the space occupied is small, the practicability is strong, and it has a strong promotion significance.

[0035] The above-mentioned embodiment only expresses one implementation method of the utility model, and its description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
