Description

Technical Field

[0001] This utility model relates to a jewelry processing equipment, and more particularly to a figure-6 circular filigree forming machine. Background Technology

[0002] Filigree is a decorative technique that uses threads of metal or other materials, bent into specific shapes and patterns, and then extensively applied to the surface of ornaments to significantly enhance their aesthetic appeal. For example... Figure 1 As shown, it is a 200-type filigree piece with a figure-6 shape, which is a type of gold filigree jewelry made by shaping gold wire into the shape of a figure-6.

[0003] Current filigree forming methods typically involve manually bending gold wire into shape using forming molds. This manual processing method is not only inefficient but also results in inconsistent quality of the formed filigree pieces, severely impacting the final decorative effect. Furthermore, the tiny size of the filigree makes manual processing quite challenging. Utility Model Content

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of the utility model.

[0027] like Figures 2 to 13 As shown, this utility model provides a figure-six circular filigree forming machine 100, which includes a mounting plate 10, a feeding assembly 20, a cutting assembly 30, a fixing assembly 40, a bending assembly 50, and a forming assembly 60. The feeding assembly 20, cutting assembly 30, fixing assembly 40, bending assembly 50, and forming assembly 60 are all mounted on the mounting plate 10. The feeding assembly 20, cutting assembly 30, and fixing assembly 40 are arranged horizontally in sequence. The bending assembly 50 is arranged around the fixing assembly 40, and the forming assembly 60 is located in front of the fixing assembly 40. A support plate 11 is provided on the mounting plate 10, and the support plate 11 is located below the fixing assembly 40 and the forming assembly 60. It is understood that this utility model also includes several power supply, air supply, and sensor structures, as well as an automated control system. Since these are all conventional technologies in this field, they will not be described in detail.

[0028] The feeding assembly 20 includes a feeding slide rail 21, a feeding carriage 22, a clamping frame 23, a clamping cylinder 24, a pushing cylinder 25, and a clamping cylinder 26. The feeding slide rail 21 is fixedly mounted on the mounting plate 10 in a left-right direction. The feeding carriage 22 is snapped onto the feeding slide rail 21 and can slide left and right. The feeding carriage 22 is also provided with a clamping through hole 221 extending left and right. The clamping frame 23 is fixedly mounted on the right side of the feeding slide rail 21. The clamping frame 23 is also provided with a clamping through hole 231 extending left and right. The clamping cylinder 24 is mounted on the upper end of the feeding carriage 22 and extends into the clamping through hole 221. The pushing cylinder 25 is mounted on the left side of the feeding slide rail 21 and is poweredly connected to the feeding carriage 22. The clamping cylinder 26 is mounted on the clamping frame 23 and extends into the clamping through hole 231.

[0029] The metal wire is sequentially threaded through the clamping through-hole 221 of the feeding slide 22 and the clamping through-hole 231 of the clamping frame 23. During feeding, the feeding slide 22 is initially located at the leftmost position of the feeding slide rail 21. The clamping cylinder 24 clamps and fixes a section of the metal wire in the clamping through-hole 221. Then, the pushing cylinder 25 is activated to push the feeding slide 22 to slide to the right, and the metal wire is also clamped and moved to the right. When the feeding slide 22 slides to the right side of the feeding slide rail 21, the clamping cylinder 24 releases the clamping of the metal wire, and the clamping cylinder 26 clamps and fixes a section of the metal wire located in the clamping through-hole 231. Then, the pushing cylinder 25 drives the clamping cylinder 24 to slide to the left to reset it.

[0030] The feeding assembly 20 also includes a guide block 27, which is fixedly mounted on the mounting plate 10 and located on the left side of the feeding slide rail 21. The guide block 27 is also provided with a through hole 271 extending from left to right. The guide block 27 with the through hole 271 can straighten the metal wire before feeding, thereby avoiding bending and knotting of the metal wire during the feeding process, which would ultimately affect the feeding and even subsequent filigree forming processing.

[0031] The cutting assembly 30 includes a cutting slide 31, a cutting blade 32, and a cutting cylinder 33. The cutting slide 31 is engaged with the right side of the clamping frame 23 and can be moved up and down. The cutting blade 32 is fixedly mounted on the cutting slide 31 and extends downward. The cutting cylinder 33 is mounted on the top of the clamping frame 23 and located above the cutting slide 31. The cutting cylinder 33 is poweredly connected to the cutting slide 31. When the metal wire is simultaneously clamped and fixed by the clamping cylinder 26 and the fixing assembly 40, the cutting cylinder 33 will start working, driving the cutting slide 31 and the cutting blade 32 to cut the metal wire into small segments of fixed length, so that the subsequent components can bend and shape these small segments of wire.

[0032] The fixing assembly 40 includes a fixing plate 41, a fixing rod 42, a fixing pin 43, a first fixing cylinder 44, and a second fixing cylinder 45. The fixing plate 41 is fixedly mounted on the mounting plate 10. The fixing rod 42 passes through the fixing plate 41 and the mounting plate 10 in the front-to-back direction. The fixing rod 42 has a crescent-shaped cross-section. The fixing pin 43 is engaged with the fixing plate 41 in the vertical direction and is located below the fixing rod 42. The first fixing cylinder 44 is mounted on the rear side of the mounting plate 10 and is poweredly connected to the fixing rod 42. The second fixing cylinder 45 is mounted on the bottom of the fixing plate 41 and is poweredly connected to the fixing pin 43.

[0033] During the feeding process, the metal wire is transferred between the fixed clamping rod 42 and the fixed clamping pin 43. When it is necessary to clamp and fix the metal wire, the fixed clamping rod 42 is pushed forward by the first fixed cylinder 44, while the fixed clamping pin 43 is pushed upward and extended outward by the second fixed cylinder 45, thus clamping and fixing the metal wire together with the fixed clamping rod 42. After the metal wire is clamped and formed into a filigree product by the bending component 50 and the forming component 60, the first fixed cylinder 44 drives the fixed clamping rod 42 to retract backward, and at the same time, the second fixed cylinder 45 also drives the fixed clamping pin 43 to descend and retract inward to reset. Then the filigree product will automatically fall off the fixed clamping pin 43 and be unloaded.

[0034] The bending assembly 50 includes a first bending push plate 51, a second bending push plate 52, a first push-pull cylinder 53, and a second push-pull cylinder 54. The first bending push plate 51 is latched onto the right side of the fixed plate 41 in a left-right direction and can slide left and right. The second bending push plate 52 is latched onto the lower left side of the fixed plate 41 at an angle and can slide at an angle. One end of both the first and second bending plates points towards the fixed clamping rod 42. The first push-pull cylinder 53 is fixedly mounted on the right side of the fixed plate 41 and is poweredly connected to the first bending push plate 51. The second push-pull cylinder 54 is fixedly mounted on the mounting plate 10 and is poweredly connected to the second bending push plate 52. Driven by their respective push-pull cylinders, the two sets of bending push plates can pre-bend the clamped metal wire, allowing the forming assembly 60 to better guide the wire for further bending and shaping. After the filigree product is formed, the two sets of bending push plates can bend the outer side of the product again to solidify it, so as to ensure that the shape of each filigree product remains highly uniform.

[0035] The molding assembly 60 includes a molding slide rail 61, a molding carriage 62, a molding shaft 63, a rotary motor 64, a cylinder mounting bracket 65, and a molding cylinder 66. The molding slide rail 61 is fixedly mounted on the mounting plate 10 in a front-to-back direction. The molding carriage 62 is engaged with the molding slide rail 61 and can slide back and forth. The molding shaft 63 and the rotary motor 64 are both mounted on the molding carriage 62, and the molding shaft 63 is poweredly connected to the rotary motor 64. The cylinder mounting bracket 65 is fixedly mounted on the mounting plate 10 and extends forward. The molding cylinder 66 is mounted on the cylinder mounting bracket 65 and located in front of the molding carriage 62, and the molding cylinder 66 is poweredly connected to the molding carriage 62. One end of the molding shaft 63 is also provided with a molding protrusion 631.

[0036] In the process of bending the metal wire into a filigree product, the forming cylinder 66 first pushes the forming carriage 62 to slide backward along the forming slide rail 61. At the same time, the forming shaft 63 gradually approaches the fixing clamp 42, the fixing clamp 43, and the metal wire clamped and fixed by the two. When the forming protrusion 631 at the end of the forming shaft 63 is on the same vertical plane as the metal wire, the rotary motor 64 will start to drive the forming shaft 63 to rotate. Under the action of the forming protrusion 631 on the forming shaft 63, the metal wire will bend continuously until a spiral figure-6 circular filigree product 200 is formed.

[0037] In summary, the beneficial effects of this utility model's 6-shaped circular filigree forming machine 100 are as follows: by designing automated components to feed, clamp, bend, and finally form the metal wire into a 6-shaped circular filigree 200, it not only greatly improves production efficiency compared to conventional manual processing methods, but also makes the automatic forming method more stable and reliable, resulting in more uniform filigree quality. This utility model is highly practical and has significant promotional value.

[0038] The embodiments described above illustrate only one implementation of the utility model, and while the description is relatively specific and detailed, it should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the inventive concept, and these all fall within the protection scope of the utility model. Therefore, the protection scope of the utility model patent should be determined by the appended claims.
