[0031] The output end of the second hydraulic cylinder 8 of this utility model will drive the second U-shaped bracket 9 to move to the inside of the support plate 12 above the corresponding punch 14. Then, the output end of the third hydraulic cylinder 16 can drive the third U-shaped bracket 17 to move to the outside of the connecting block 13 fixedly connected to the top of the corresponding punch 14. At this time, the output end of the fourth hydraulic cylinder 18 will drive the insert plate 20 to be inserted into the corresponding slot 21 through the second connecting plate 19, and the electromagnet 22 will be energized and work, and will be attracted and fixed to the metal connecting block 13, so as to facilitate the automatic selection of punch 14 that meets the processing requirements.
[0032] Specifically,
[0033] An electromagnet 22 is installed inside the plug plate 20, and the connecting block 13 is a metal part.
[0034] Specifically, after the electromagnet 22 is energized, it can be attracted and fixed to the connecting block 13, thereby fixing the connecting block 13 to the inside of the third U-shaped bracket 17.
[0035] Multiple limiting holes 15 are provided on the inner side of the support plate 12, and the multiple limiting holes 15 correspond one-to-one with multiple punches 14.
[0036] Specifically, by opening a limiting hole 15 on the inner side of the support plate 12, the limiting hole 15 has a certain limiting effect on the punch 14, thereby improving the stability of the punch 14 placed on the inner side of the support plate 12.
[0037] A guide rail 11 is provided on the outer side of the punching table 1, and a slider 10 is fixedly connected to the bottom of the second U-shaped bracket 9. The slider 10 is slidably connected to the guide rail 11.
[0038] Specifically, when the second U-shaped bracket 9 is powered to move, because the bottom of the second U-shaped bracket 9 is fixedly connected to the slider 10, and the slider 10 matches the guide rail 11, the slider 10 will slide on the guide rail 11 and improve the stability of the second U-shaped bracket 9 when it moves.

The output end of the first hydraulic cylinder 4 drives the fixed frame 6 to move downward through the first connecting plate 5 and presses and fixes the bathroom cabinet shelf shell on the top of the punching platform 1, so as to facilitate the subsequent stable punching operation of the bathroom cabinet shelf shell.
[0041] A through groove 2 is provided on the inner side of the punching platform 1, and a collection box 23 is fixedly connected to the bottom of the punching platform 1. The collection box 23 is connected to the through groove 2.
[0042] Specifically, the waste generated when the punch 14 punches holes in the outer shell of the bathroom cabinet shelf will enter the collection box 23 through the through groove 2, making it convenient to collect and process the waste generated when punching holes in the outer shell of the bathroom cabinet shelf.
[0043] A sealing plate 24 is provided on one side of the collection box 23.
[0044] Specifically, a sealing plate 24 is provided on one side of the collection box 23. The sealing plate 24 has a sealing effect on the collection box 23. After opening the sealing plate 24, it is convenient to discharge the waste accumulated inside the collection box 23.
[0045] Working principle:
[0046] When punching holes in the outer shell of a bathroom cabinet shelf, the outer shell of the bathroom cabinet shelf is first placed on the corresponding position on the top of the punching platform 1. Then, the first hydraulic cylinder 4, which is fixedly installed on the top of the first U-shaped bracket 3, is activated. The output end of the first hydraulic cylinder 4 drives the fixed frame 6 to move downward through the first connecting plate 5 and presses and fixes the outer shell of the bathroom cabinet shelf on the top of the punching platform 1, which facilitates the subsequent stable punching operation of the outer shell of the bathroom cabinet shelf.
[0047] Next, the output end of the second hydraulic cylinder 8 will drive the second U-shaped bracket 9 to move to the inside of the support plate 12 above the corresponding punch 14. Then, the output end of the third hydraulic cylinder 16 can drive the third U-shaped bracket 17 to move to the outside of the connecting block 13 fixedly connected to the top of the corresponding punch 14. At this time, the output end of the fourth hydraulic cylinder 18 will drive the insert plate 20 to be inserted into the corresponding slot 21 through the second connecting plate 19, and the electromagnet 22 will be energized and attracted and fixed to the metal connecting block 13, so as to facilitate the automatic selection of punch 14 that meets the processing requirements.
[0048] Subsequently, the output end of the third hydraulic cylinder 16 will drive the connecting block 13 and the punch 14 to move upward and separate from the support plate 12. The output end of the second hydraulic cylinder 8 will drive the second U-shaped bracket 9 and the punch 14 inside the second U-shaped bracket 9 to move above the through groove 2. Then, the output end of the third hydraulic cylinder 16 will drive the third U-shaped bracket 17 and the punch 14 to move downward, facilitating the punching operation on the bathroom cabinet shelf shell at the top of the punching table 1.
[0049] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
