[0028] 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

[0029] 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.

[0030] Please refer to Figures 1 to 7This utility model proposes a solid jewelry processing equipment. The preferred embodiment of this utility model includes a main shaft 1, a main shaft rotation drive mechanism, a lower mold 8, a product ejection mechanism, an upper mold 11, and an upper mold drive mechanism.

[0031] The top of the main shaft 1 is provided with a groove 2 for placing the lower mold 8. The center of the lower mold 8 is provided with a processing hole 9 for placing the jewelry to be processed. The main shaft rotation drive mechanism is used to drive the main shaft 1 to rotate, thereby driving the lower mold 8 and the jewelry to be processed inside the lower mold 8 to rotate. The jewelry to be processed is, for example, a solid ring, a bracelet, etc.

[0032] The upper mold 11 is located above the lower mold 8. The upper mold driving mechanism is used to drive the upper mold 11 to move up and down relative to the lower mold 8. During processing, the upper mold 11 extends into the center of the jewelry to be processed and presses the jewelry to be processed against the inner wall of the processing hole 9 of the lower mold 8.

[0033] The product ejection mechanism is used to eject the finished jewelry from the lower mold 8 after processing.

[0034] In this embodiment, before processing, a lower mold 8 of appropriate size (specifically, a lower mold 8 with a corresponding processing hole 9 size can be selected according to the size of the jewelry to be processed) is first placed into the groove 2 of the main shaft 1. Then, the jewelry to be processed is placed into the processing hole 9 of the lower mold 8. The main shaft rotation drive mechanism and the upper mold drive mechanism are then activated. At this time, the main shaft rotation drive mechanism drives the main shaft 1 to rotate, which in turn drives the lower mold 8 and the jewelry to be processed to rotate. At the same time, the upper mold drive mechanism drives the upper mold 11 to descend until it extends into the center of the jewelry to be processed, pressing the jewelry to be processed against the inner wall of the processing hole 9 of the lower mold 8. Under the action of the rotation of the lower mold 8 and the pressing force of the upper mold 11, the jewelry to be processed is extruded and shaped. After processing, the product ejection mechanism rises and resets, and the output shaft of the product ejection mechanism rises to eject the processed jewelry from the lower mold 8.

[0035] Therefore, this embodiment realizes the automated forming of jewelry to be processed, improving the production efficiency and yield of jewelry processing.

[0036] Furthermore, in this embodiment, the main shaft rotation drive mechanism includes: a drive motor 5, a main drive wheel 6, and a secondary drive wheel 7. The output shaft of the drive motor 5 is connected to the main drive wheel 6, and the secondary drive wheel 7 is connected to the main shaft 1. The main drive wheel 6 and the secondary drive wheel 7 are linked together.

[0037] Specifically, the main drive wheel 6 and the auxiliary drive wheel 7 can be connected by a timing belt. When the output shaft of the drive motor 5 rotates, it drives the main drive wheel 6 and the auxiliary drive wheel 7 to rotate synchronously, thereby driving the main shaft 1 to rotate.

[0038] Furthermore, in this embodiment, the main shaft 1 has a through hole 3 at its center, and the product ejection mechanism includes a lifting cylinder 10. The output shaft of the lifting cylinder 10 passes through the through hole 3 of the main shaft 1. After processing, the output shaft of the lifting cylinder 10 extends into the processing hole 9 of the lower mold 8 and ejects the processed jewelry from the lower mold 8.

[0039] Furthermore, in this embodiment, the upper mold driving mechanism includes an upper mold driving cylinder 12, a cylinder mounting plate 13, and a slider 14. The upper mold driving cylinder 12 is disposed on the top of the cylinder mounting plate 13, and the slider 14 is slidably disposed on the cylinder mounting plate 13. The output shaft of the upper mold driving cylinder 12 is connected to the top of the slider 14, and the upper mold 11 is fixedly connected to one side of the slider 14.

[0040] Furthermore, in this embodiment, the solid jewelry processing equipment also includes a spindle micro-adjustment mechanism for fine-tuning the horizontal position of the spindle 1.

[0041] This embodiment takes into account that there may be gaps between the upper mold 11 and the jewelry to be processed, and between the jewelry to be processed and the inner wall of the lower mold 8, which may lead to uneven clamping force during processing and reduce product yield. Therefore, this embodiment is provided with a spindle micro-adjustment mechanism for finely adjusting the horizontal position of the spindle 1.

[0042] Specifically, in this embodiment, a spindle bearing sleeve 4 is fitted around the outer periphery of the spindle 1, and the spindle micro-adjustment mechanism includes a micro-adjustment cylinder 15, the output shaft of which is horizontally connected to the spindle bearing sleeve 4.

[0043] In this embodiment, the main shaft micro-adjustment mechanism further includes a power dovetail plate 16, which has an elliptical adjustment groove. The main shaft 1 passes through the adjustment groove so that the output shaft of the micro-adjustment cylinder 15 can drive the micro-adjustment of the horizontal position of the main shaft 1, thereby adjusting the clamping force of the upper mold 11 and the lower mold 8 on the jewelry to be processed.

[0044] Furthermore, in this embodiment, a sealing plate 17 is provided on the power dovetail plate 16.

[0045] Furthermore, in this embodiment, the solid jewelry processing equipment also includes a frame 18, on which the main shaft 1, the main shaft rotation drive mechanism, the lower mold 8, the product ejection mechanism, the upper mold 11, and the upper mold drive mechanism are all mounted.

[0046] In summary, the beneficial effects of this utility model's solid jewelry processing equipment are:

[0047] 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 is used to drive the main shaft to rotate, thereby driving the lower mold and the jewelry to be processed inside the lower mold to rotate; the upper mold is located above the lower mold, and the upper mold drive mechanism is used to drive the upper mold to move up and down relative to the lower mold; during processing, the upper mold extends into the center of the jewelry to be processed, pressing the jewelry to be processed against the inner wall of the processing hole of the lower mold; the product ejection mechanism is used to eject the processed jewelry from the lower mold after processing, thereby improving the jewelry processing efficiency and yield.
