[0002] Lamp processing involves multiple steps from design, manufacturing to final assembly of lamps. Lamps are not only lighting tools, but are often designed as interior decorations. Therefore, lamp processing needs to take into account both functionality and aesthetics. In order to facilitate the installation of screws, nuts or other fasteners and ensure that the lampshade can be firmly fixed on the lamp body, a punching device for lamp processing is required.

[0003] In the process of using the punching device for traditional lamp processing, a rotating tool or punch is driven by mechanical force or electric force to exert pressure on the surface of the workpiece, thereby forming a hole of the desired shape and size.

[0004] However, it did not solve the problem that after the punching of the lamp is completed, the waste generated by the punching is embedded in the lower mold, which requires the operator to use tools to lift it out and the machine needs to be stopped during the cleaning process, affecting the production efficiency of the punching device used for lamp processing. Utility Model Content

[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] Reference Figure 1 and Figure 2 The utility model provides an embodiment: a punching device for lamp processing, comprising a frame 1, a top plate 2 is fixedly connected to the top of the frame 1, a hydraulic rod 3 is fixedly connected inside the top plate 2, an upper mold 4 is fixedly connected to the output end of the hydraulic rod 3, a lower mold 5 is fixedly connected to the top of the frame 1, a limiting column 1 7 is fixedly connected inside the frame 1, a limiting column 2 8 is fixedly connected inside the frame 1, a top column 12 is slidably connected inside the limiting column 2 8, a support plate 9 is fixedly connected to the bottom of the top column 12, and the support plate 9 The inner part is slidably connected to the outer wall of the limit column 17, the top of the support plate 9 is fixedly connected to the connecting rod 10, the bottom of the upper mold 4 is fixedly connected to the connecting rod 16, the connecting rod 16 is embedded with one end of the connecting rod 10, and the outer wall of the limit column 17 is provided with a reset component, which is used to retract the top column 12 into the inside of the limit column 28, and the reset component includes a spring 11, the inner part of the spring 11 is sleeved on the outer wall of the limit column 17, one end of the spring 11 is fixedly connected to the inside of the frame 1, and the other end of the spring 11 is fixedly connected to the top of the support plate 9;

[0032] Specifically, the output end of the hydraulic rod 3 extends outward, thereby driving the upper mold 4 to move downward. When the upper mold 4 is precisely aligned with the lower mold 5, they will be tightly buckled together to perform a punching operation on the lamp. In this process, the waste generated by punching will be smoothly guided to the limiting column 2 8. After the punching operation is completed, the output end of the hydraulic rod 3 begins to retract, which causes the upper mold 4 to lift upward. In this process, the connecting rod 1 6 and the connecting rod 2 10 are buckled with each other, thereby driving the support plate 9 to move upward. The movement of the support plate 9 further drives the ejector column 12 to extend out of the limiting column 2 8 to eject the waste from the limiting column 2 8. In the subsequent punching process, the connecting rod 1 6 will drop, thereby releasing the connecting rod 2 10. At this time, the ejector column 12 is retracted into the limiting column 2 8 under the tension of the spring 11 to achieve automatic resetting. In this way, the entire punching operation is successfully completed.

[0033] Reference Figure 3 and Figure 4 , a fixing ring 13 is fixedly connected to the top of the lower mold 5, a motor 14 is fixedly connected to the outer wall of the fixing ring 13, a gear 15 is fixedly connected to the output end of the motor 14, a limiting ring 16 is rotatably connected to the top of the fixing ring 13, an arc groove 22 is provided inside the limiting ring 16, a tooth block 17 is fixedly connected to the outer wall of the limiting ring 16, the tooth block 17 is meshed with the outer wall of the gear 15, a positioning groove 18 is provided inside the fixing ring 13, a slider 19 is arranged inside the fixing ring 13, the outer wall of the slider 19 is slidably connected to the inside of the positioning groove 18, a limiting block 20 is fixedly connected to the top of the slider 19, the outer wall of the limiting block 20 is slidably connected to the inside of the arc groove 22, and a clamping plate 21 is fixedly connected to the top of the limiting block 20;

[0034] Specifically, first, place the lamp between the clamping plates 21. Next, the output end of the motor 14 starts working to drive the gear 15 to rotate. The function of the gear 15 is to transmit the power of the motor 14 and transmit it to the next component. Driven by the gear 15, the tooth block 17 starts to rotate. The tooth block 17 is connected to the limit ring 16. As the tooth block 17 rotates, the limit ring 16 also rotates. This step is to ensure that the lamp always maintains the correct position during the installation process. When the limit ring 16 rotates, it guides the slider 19 at the bottom of the limit block 20 to move through the arc groove 22. The slider 19 slides in the arc groove 22, so that the limit block 20 can closely follow the shape of the lamp to achieve all-round fixation of the lamp. Finally, the slider 19 is relatively closed by the positioning groove 18 in the fixing ring 13. This step is to ensure that the limit block 20 will not loosen during the installation process, so that the limit block 20 can firmly clamp the lamp.

[0035] Working principle: When the punching device for lamp processing is used, the lamp is first installed by placing it between the clamping plates 21, and then the output end of the motor 14 drives the gear 15 to rotate, and the gear 15 drives the limit ring 16 to rotate through the tooth block 17. When the limit ring 16 rotates, the slider 19 at the bottom of the limit block 20 is guided to move through the arc groove 22. The slider 19 is relatively closed through the positioning groove 18 in the fixing ring 13, so that the limit block 20 clamps and fixes the lamp, and then the output end of the hydraulic rod 3 extends to drive the upper mold 4 to move downward. The upper mold 4 and the lower mold 5 are engaged with each other to punch the lamp, and then the waste generated by the punching falls into the limiting column 8. When the output end of the hydraulic rod 3 retracts and drives the upper mold 4 to be lifted, the supporting plate 9 is driven to rise through the engagement of the connecting rod 1 6 and the connecting rod 2 10. The supporting plate 9 drives the top column 12 to extend out of the limiting column 2 8 to eject the waste in the limiting column 2 8. Then, in the next punching process, the connecting rod 1 6 descends to release the connecting rod 2 10, and the top column 12 is supported by the tension of the spring 11 and drives the top column 12 to retract into the limiting column 2 8 to reset.

[0036] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
