Description

Technical Field

[0001] This utility model relates to the field of jewelry processing equipment technology, and in particular to a solid jewelry processing device. Background Technology

[0002] Jewelry processing refers to all the processes that process various jewelry raw materials into finished products according to their various forms. Common precious metal jewelry processing usually adopts traditional hand processing techniques. Solid structure jewelry (such as solid rings, bracelets, etc.) is formed by hammering. This method is not only inefficient, but also has a low yield.

[0003] To solve this technical problem, existing technologies employ automated solid jewelry processing and forming equipment. However, current automated solid jewelry processing and forming equipment typically uses a lower mold 1 that is finely adjustable on a frame 3 via a main shaft 2. During operation, a cylinder 4 located below the frame 3 is used to finely adjust the main shaft 2, thereby adjusting the pressure of the upper mold 5 on the product placed in the lower mold 1, achieving extrusion molding of the product (e.g., ...). Figure 1 and Figure 2 (As shown).

[0004] However, this solution is prone to low product yield and low production efficiency due to equipment vibration during operation, since both the lower mold 1 and cylinder 4 are mounted on the frame and the lower mold and spindle are movable. Utility Model Content

[0005] The main purpose of this invention is to provide a solid jewelry processing device, which aims to improve the efficiency and yield of jewelry processing.

[0006] To achieve the above objectives, this utility model provides a solid jewelry processing device, including: a frame, a main shaft, a main shaft rotation drive mechanism, a lower mold, a product ejection mechanism, an upper mold, an upper mold drive mechanism, and an upper mold drive mechanism fine-tuning mechanism;

[0007] The main shaft is fixedly mounted on the frame. The top of the main shaft is provided with a groove for placing the lower mold, and the center of the lower mold is provided with a processing hole for placing the jewelry to be processed.

[0008] The spindle rotation drive mechanism is located below the frame and is used to drive the spindle to rotate, thereby driving the lower mold and the jewelry to be processed inside the lower mold to rotate.

[0009] The upper mold driving mechanism and the upper mold driving mechanism fine-tuning mechanism are disposed above the frame. The upper mold is connected to the upper mold driving mechanism. The upper mold driving mechanism is used to drive the upper mold to move up and down relative to the lower mold. The upper mold driving mechanism fine-tuning mechanism is used to fine-tune the upper mold driving mechanism to press the jewelry to be processed against the inner wall of the processing hole of the lower mold.

[0010] The product ejection mechanism is located below the frame and is used to eject the finished jewelry from the lower mold after processing.

[0011] A further technical solution of this utility model is that the main shaft rotation drive mechanism includes: a drive motor, a main drive wheel and a secondary drive wheel, the output shaft of the drive motor is connected to the main drive wheel, the secondary drive wheel is connected to the main shaft, and the main drive wheel and the secondary drive wheel are linked together.

[0012] A further technical solution of this utility model is that a through hole is provided in the center of the main shaft, and the product ejection mechanism includes a lifting cylinder. The output shaft of the lifting cylinder passes through the through hole of the main shaft. After processing, the output shaft of the lifting cylinder extends into the processing hole of the lower mold to eject the product.

[0013] A further technical solution of this utility model is that the upper mold driving mechanism includes an upper mold driving cylinder, a cylinder mounting plate and a slider. The upper mold driving cylinder is disposed on the top of the cylinder mounting plate, the slider is slidably disposed on the cylinder mounting plate, the output shaft of the upper mold driving cylinder is connected to the top of the slider, and the upper mold is fixedly connected to one side of the slider.

[0026] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0028] This utility model proposes a solid jewelry processing device, such as... Figures 3 to 8 As shown, a preferred embodiment of the solid jewelry processing device of this utility model includes: a frame 5, a main shaft 6, a main shaft rotation drive mechanism, a lower mold 7, a product ejection mechanism, an upper mold 8, an upper mold drive mechanism, and an upper mold drive mechanism fine adjustment mechanism.

[0029] The main shaft 6 is fixedly mounted on the frame 5. The top of the main shaft 6 is provided with a groove 9 for placing the lower mold 7. The center of the lower mold 7 is provided with a processing hole 10 for placing the jewelry to be processed.

[0030] The spindle rotation drive mechanism is located below the frame 5 and is used to drive the spindle 6 to rotate, thereby driving the lower mold 7 and the jewelry to be processed inside the lower mold 7 to rotate.

[0031] The upper mold driving mechanism and the upper mold driving mechanism fine-tuning mechanism are disposed above the frame 5. The upper mold 8 is connected to the upper mold driving mechanism. The upper mold driving mechanism is used to drive the upper mold 8 to move up and down relative to the lower mold 7. The upper mold driving mechanism fine-tuning mechanism is used to fine-tune the upper mold driving mechanism to press the jewelry to be processed against the inner wall of the processing hole 10 of the lower mold 7.

[0032] The product ejection mechanism is located below the frame 5 and is used to eject the finished jewelry from the lower mold 7 after processing.

[0033] In this embodiment, the spindle 6 is fixedly mounted on the frame 5, and the upper mold drive mechanism fine-tuning mechanism is located above the frame 5. It is used to fine-tune the upper mold drive mechanism to press the jewelry to be processed against the inner wall of the processing hole 10 of the lower mold 7. This can avoid product defects caused by the vibration of the spindle 6 during operation, thereby improving product yield and work efficiency.

[0034] In this embodiment, before processing, a lower mold 7 of appropriate size (specifically, a lower mold 7 with a corresponding processing hole 10 size can be selected according to the size of the jewelry to be processed) is first placed into the groove 9 of the main shaft 6. Then, the jewelry to be processed is placed into the processing hole 10 of the lower mold 7. Next, the main shaft rotation drive mechanism and the upper mold drive mechanism are activated. At this time, the main shaft rotation drive mechanism drives the main shaft 6 to rotate, thereby driving the lower mold 7 and the jewelry to be processed to rotate. Simultaneously, the upper mold drive mechanism drives the upper mold 8 to descend until it extends into the center of the jewelry to be processed, thus placing the jewelry to be processed... The jewelry is pressed against the inner wall of the processing hole 10 of the lower mold 7. Under the rotation of the lower mold 7 and the clamping force of the upper mold 8, the jewelry to be processed is extruded and formed. During the processing, the upper mold drive mechanism fine-tunes the upper mold drive mechanism to press the jewelry to be processed against the inner wall of the processing hole 10 of the lower mold 7, thereby avoiding product defects caused by the vibration of the spindle 6 during operation, thus improving product yield and work efficiency. After processing is completed, the output shaft of the product ejection mechanism rises and ejects the processed jewelry from the lower mold 7.

[0035] Furthermore, in this embodiment, the main shaft rotation drive mechanism includes: a drive motor 11, a main drive wheel 12 and a secondary drive wheel 13. The output shaft of the drive motor 11 is connected to the main drive wheel 12, and the secondary drive wheel 13 is connected to the main shaft 6. The main drive wheel 12 and the secondary drive wheel 13 are linked together.

[0036] Specifically, the main drive wheel 12 and the auxiliary drive wheel 13 can be connected by a timing belt. When the output shaft of the drive motor 11 rotates, it drives the main drive wheel 12 and the auxiliary drive wheel 13 to rotate synchronously, thereby driving the main shaft 6 to rotate.

[0037] Furthermore, in this embodiment, the main shaft 6 has a through hole 14 at its center, and the product ejection mechanism includes a lifting cylinder 15. The output shaft of the lifting cylinder 15 passes through the through hole 14 of the main shaft 6. After processing, the output shaft of the lifting cylinder 15 extends into the processing hole 10 of the lower mold 7 to eject the product.

[0038] Furthermore, in this embodiment, the upper mold driving mechanism includes an upper mold driving cylinder 16, a cylinder mounting plate 17, and a slider 18. The upper mold driving cylinder 16 is disposed on the top of the cylinder mounting plate 17, and the slider 18 is slidably disposed on the cylinder mounting plate 17. The output shaft of the upper mold driving cylinder 16 is connected to the top of the slider 18, and the upper mold 8 is fixedly connected to one side of the slider 18.

[0039] Furthermore, in this embodiment, the fine-tuning mechanism of the upper mold drive mechanism includes a fine-tuning cylinder 19 and an X-axis dovetail plate 20 disposed on the frame 5, the cylinder mounting plate 17 is slidably disposed on the X-axis dovetail plate 20, and the output shaft of the fine-tuning cylinder 19 is connected to the cylinder mounting plate 17.

[0040] During operation, the fine-tuning cylinder 19 makes fine adjustments to the cylinder mounting plate 17, thereby adjusting the pressure between the upper mold 8 and the inner wall of the processing hole 10 of the lower mold 7 to ensure a high processing yield.

[0041] In summary, the beneficial effects of this utility model's solid jewelry processing device are:

[0042] This utility model, through the above-described technical solution, includes: a main shaft, a main shaft rotation drive mechanism, a lower mold, a product ejection mechanism, an upper mold, and an upper mold drive mechanism. The top of the main shaft is provided with a groove for placing the lower mold, and the center of the lower mold is provided with a processing hole for placing the jewelry to be processed. The main shaft rotation drive mechanism drives the main shaft to rotate, thereby rotating the lower mold and the jewelry to be processed within it.
