[0023] Embodiment:

[0024] As shown in the attached Figure 1 to the attached Figure 5 figure:

[0025] The utility model provides a bending mechanism for gold jewelry processing, including a base 1. The top of the base 1 is fixedly connected with a fixed box body 2. A placement groove is opened at the top of the fixed box body 2. An elastic component 3 is arranged inside the fixed box body 2. The top of the elastic component 3 is connected with a lower die 4. The lower die 4 is slidably installed in the placement groove. The top of the base 1 is fixedly connected with a mounting frame 5. A hydraulic cylinder 6 is fixedly installed at the top of the mounting frame 5. The telescopic end of the hydraulic cylinder 6 is connected with a fixed block 7. The fixed block 7 is connected with an upper die 9 through a mounting component 8.

[0026] Among them, the mounting component 8 includes L-shaped frames 802 fixedly installed on the left and right sides of the fixed block 7. A locking rod 803 is horizontally penetrated and installed at the vertical end of the L-shaped frame 802. One end of the locking rod 803 is fixedly connected with a pull ring 806 outside the L-shaped frame 802. An installation groove is arranged at the bottom side of the fixed block 7. Through holes for the locking rod 803 to penetrate are correspondingly arranged on the left and right sides of the installation groove. The top of the upper die 9 is provided with a connecting block matching the installation groove. Locking holes 801 connected with the locking rod 803 are arranged on the left and right sides of the connecting block, so as to quickly lock the connecting block of the upper die 9, and it has high disassembly and assembly convenience.

[0027] Among them, a limiting ring 804 is fixedly installed on the outer side of the locking rod 803. A first spring 805 is sleeved on the outer side of the locking rod 803. Both ends of the first spring 805 are abutted against the limiting ring 804 and the L-shaped frame 802, so as to push the locking rod 803 to stably lock the connecting block under the action of the first spring 805 to ensure stable bending operation.

[0028] Among them, the elastic component 3 includes a mounting cylinder body 301 fixedly installed at the center inside the fixed box body 2. One end of the mounting cylinder body 301 is connected with a support shaft 302. A second spring 303 is arranged between the mounting cylinder body 301 and the support shaft 302. Through the arrangement of the second spring 303, after the bending is completed, the jewelry can be quickly pushed out, so as to facilitate the operator to quickly take the material. The top of the support shaft 302 is fixedly connected with a connecting plate 304. The top of the connecting plate 304 is fixedly connected with a limiting column 305. A connecting hole inserted with the limiting column 305 is arranged at the bottom end of the lower die 4, so as to quickly disassemble and replace the lower die 4.

[0029] Among them, two groups of sliding rods 306 are connected to both sides of the connecting plate 304. Two groups of through grooves are arranged on both side walls of the fixed box body 2. One ends of the sliding rods 306 all penetrate through the through grooves and extend to the outside of the fixed box body 2 to improve the smoothness of the up and down movement of the connecting plate 304 and improve the bending efficiency.

[0030] Wherein, both sides of the top end of the fixed box body 2 are slidably connected with limit blocks 10. A chute is formed at the top end of each limit block 10, and a fastening bolt 11 is connected in the chute. Threaded holes connected with the fastening bolts 11 are arranged at the top ends of the fixed box bodies 2, so that the position of the limit block 10 can be quickly adjusted during use, and the ornament strip can be quickly positioned before bending, thereby improving the accuracy of bending.

[0031] Wherein, a plurality of support legs 12 are fixedly installed at the bottom of the base 1, and anti-slip rubber pads are arranged on the support legs 12 to ensure high stability during the operation of the whole device.

[0032] The working principle of this embodiment:

[0033] During use, place the gold ornament to be bent on the top end of the fixed box body 2 and use the limit blocks 10 for positioning. Then start the hydraulic cylinder 6, and the hydraulic cylinder 6 drives the upper die 9 to move downward. When the gold ornament is bent to an appropriate radian, the hydraulic cylinder 6 can be retracted. While the hydraulic cylinder 6 is retracting, the lower die 4 moves upward to the top end of the placement groove under the elastic action of the second spring 303, facilitating material taking. When the upper die 9 needs to be replaced, pull the locking rod 803 outward through the pull ring 806, thereby driving the limit ring 804 to compress the first spring 805, and moving one end of the locking rod 803 out of the locking hole 801 to cancel the limit on the upper die 9, then the upper die 9 can be taken off from below the fixed block 7. During installation, under the elastic action of the first spring 805, one end of the locking rod 803 is inserted into the locking hole 801 to complete the installation of the upper die 9. When the lower die 4 needs to be replaced, just lift it upward for disassembly. After disassembly, another set of lower die 4 can be installed. During installation, only need to align the connecting hole at the bottom end of the lower die 4 with the limit post 305 and insert it.
