Description

Technical Field

[0001] This utility model relates to the field of switch panel punching technology, specifically a switch panel punching device. Background Technology

[0002] Switch panels are electrical switches and sockets installed on walls. They are also classified by size, such as 86, 118, 120, and 146 types, with 86 being the standard panel size in my country and the most widely used. The most common installation methods are surface-mounted and recessed. Surface-mounted switches have exposed wiring, with the junction box exposed on the outside of the wall; recessed switches have concealed wiring, with the junction box embedded in the wall. Switch panels are often manufactured using stamping and injection molding. During stamping, a punching device is needed to drill holes in the surface of the switch panel. However, existing punching devices cannot fix the material or press the sides to prevent the panel from warping, which would affect the stamping effect. Utility Model Content

[0003] The purpose of this invention is to provide a punching device for switch panels to solve the problem mentioned in the background art that the sides of the material cannot be pressed to prevent the sides of the panel from warping up and affecting the punching effect.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a punching device for a switch panel, comprising a worktable configured as an I-shaped structure, and a lower mold fixedly connected to the surface of the worktable;

[0005] A support frame is fixedly connected to the surface of the workbench, and a cylinder is fixedly connected to the surface of the support frame. The end of the cylinder is configured as a pressing structure, and the pressing structure includes: a connecting plate is fixedly connected to the end of the output shaft of the cylinder, and an upper mold is fixedly connected to the bottom of the connecting plate. A limit plate is embedded in the surface of the lower mold, and a spring is connected to the bottom of the limit plate through the bottom of the lower mold. The end of the spring is connected to the surface of the workbench.

[0006] Preferably, the workbench surface is provided with an extrusion structure, and the extrusion structure includes: a moving plate fixedly connected to the surface of the connecting plate; an airbag installed on the surface of the support frame; a pipe installed on the surface of the airbag; a nozzle installed at the other end of the pipe; two springs symmetrically connected to the surface of the support frame; a pressure plate connected to the other end of the two springs; a feed inlet embedded in the interior of the workbench; and a collection box installed inside the workbench.

[0007] The above technical solution includes a compression mechanism that can move the stamped fragments downwards, causing the debris to fall into the collection box.

[0008] Preferably, the lower mold and the upper mold are positioned correspondingly, and the lower mold and the limiting plate are slidably connected, with the limiting plate being embedded inside the lower mold.

[0009] Using the above technical solution, the upper mold moves downwards and then moves to the surface of the lower mold to press the panel.

[0010] Preferably, the lower mold has a cavity inside, and a limiting plate is disposed outside the cavity of the lower mold, and the limiting plate and the cavity of the lower mold are staggered.

[0011] By adopting the above technical solution, the limiting plate moves downward and clamps the panel, thereby increasing the stability of the panel.

[0012] Preferably, the position of the concave mold of the lower mold corresponds to the position of the feed port, and the feed port is located at the bottom of the lower mold.

[0013] Using the above technical solution, the material falls through the lower mold and enters the inside of the feed inlet.

[0014] Preferably, the end of the pipe is inserted into the inside of the feed inlet, and the nozzle is disposed inside the feed inlet.

[0015] Using the above technical solution, gas enters the pipeline through the nozzle and then enters the interior of the airbag through the pipeline.

[0016] Preferably, the bottom of the pressure plate is in contact with the surface of the airbag, and the positions of the pressure plate and the moving plate are correspondingly arranged, and the pressure plate and the support frame are slidably connected.

[0017] Using the above technical solution, the moving plate moves downward, causing it to press down on the pressure plate, which in turn compresses the airbag.

[0018] Compared with the prior art, the beneficial effects of this utility model are: the punching device for the switch panel:

[0019] 1. A downward pressing structure is set up to fix the position of the panel and prevent the side of the panel from lifting up during extrusion. The connecting plate presses down on the pressure plate, and the bottom of the pressure plate presses down on the limiting plate, so that the limiting plate presses the panel and fixes the side of the panel to the surface of the lower mold to prevent the panel from moving during extrusion.

[0020] 2. An extrusion mechanism is provided to facilitate the falling of debris after stamping. When the stamping is completed, the extrusion of the airbag disappears, and the pressure plate moves upward. The extrusion of the airbag disappears, and the airbag absorbs the air at the nozzle. At this time, a negative pressure is formed at the feed inlet, which can adsorb the material falling from the lower mold into the inside of the feed inlet, improving the practicality of the device.

[0030] 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.

[0031] Please see Figure 1-6 This utility model provides a technical solution: a punching device for a switch panel, including a worktable 10, a lower mold 20, a support frame 30, a cylinder 40, a connecting plate 401, an upper mold 402, a limiting plate 403, a first spring 404, a moving plate 50, an airbag 501, a pressure plate 502, a second spring 503, a pipe 504, a nozzle 505, a feed inlet 506, and a collection box 507;

[0032] This switch panel punching device facilitates panel fixation and prevents panel movement during punching. The specific implementation method is as follows:

[0033] The workbench 10 is configured with an I-shaped structure, and a lower mold 20 is fixedly connected to the surface of the workbench 10; a support frame 30 is fixedly connected to the surface of the workbench 10, and a cylinder 40 is fixedly connected to the surface of the support frame 30. The end of the cylinder 40 is configured with a pressing structure, and the pressing structure includes: a connecting plate 401 fixedly connected to the end of the output shaft of the cylinder 40, and an upper mold 402 fixedly connected to the bottom of the connecting plate 401; a limit plate 403 is embedded in the surface of the lower mold 20, and a spring 4 is connected to the bottom of the limit plate 403 through the bottom of the lower mold 20. 04, and the end of spring 404 is connected to the surface of workbench 10. The lower mold 20 and the upper mold 402 are positioned correspondingly, and the lower mold 20 and the limiting plate 403 are slidably connected. The limiting plate 403 is embedded inside the lower mold 20. The lower mold 20 has a cavity inside, and the limiting plate 403 is positioned outside the cavity of the lower mold 20. The limiting plate 403 and the cavity of the lower mold 20 are staggered. The cavity of the lower mold 20 is positioned corresponding to the feed port 506, and the feed port 506 is positioned at the bottom of the lower mold 20.

[0034] like Figure 1 The panel is placed on the surface of the lower mold 20. At this time, the cylinder 40 is activated to drive the connecting plate 401 to move downward. At the same time, the connecting plate 401 drives the upper mold 402 to move downward, moving the upper mold 402 above the lower mold 20. This causes the upper mold 402 to press the panel on the surface of the lower mold 20, and the panel is stamped by the upper mold 402 and the lower mold 20. During the stamping of the panel, the connecting plate 401 presses down the limiting plate 403, pushing the limiting plate 403 to move downward inside the lower mold 20. At this time, the limiting plate 403 pushes the spring 404 to contract, so that the bottom of the limiting plate 403 is in contact with the surface of the panel. At this time, the limiting plate 403 can press the panel to prevent the four sides of the panel from lifting up during stamping, and prevent the debris generated during stamping from entering the cavity of the lower mold 20.

[0035] The punching device for this switch panel can easily clean the debris generated during punching. The specific implementation method is as follows:

[0036] The workbench 10 has an extrusion structure on its surface, which includes: a moving plate 50 fixedly connected to the surface of the connecting plate 401; an airbag 501 mounted on the surface of the support frame 30; a pipe 504 mounted on the surface of the airbag 501; a nozzle 505 mounted at the other end of the pipe 504; two springs 503 symmetrically connected to the surface of the support frame 30; a pressure plate 502 connected to the other end of the springs 503; a feed inlet 506 embedded inside the workbench 10; a collection box 507 installed inside the workbench 10; the end of the pipe 504 inserted into the feed inlet 506; the nozzle 505 located inside the feed inlet 506; the bottom of the pressure plate 502 abutting against the surface of the airbag 501; the pressure plate 502 and the moving plate 50 being positioned correspondingly; and the pressure plate 502 and the support frame 30 being slidably connected.

[0037] When the starting cylinder 40 moves the connecting plate 401 downward, the connecting plate 401 moves the shifting plate 50 downward, causing the shifting plate 50 to push the pressure plate 502 downward. This causes the pressure plate 502 to move downward on the surface of the support frame 30. At this time, the pressure plate 502 presses down on the airbag 501 and simultaneously presses down on the second spring 503, causing the spring 503 to contract. This allows the gas inside the airbag 501 to enter the pipe 504 and be ejected through the nozzle 505. After the stamping is completed, the cylinder 40 moves the connecting plate 401 upward, which in turn moves the shifting plate 50 upward. The shifting plate 50 then presses down on the pressure plate 502. When the compression disappears, the pressure on spring 503 disappears, causing pressure plate 502 to move upward and return to its original position. At this time, the pressure of pressure plate 502 on airbag 501 disappears, causing airbag 501 to absorb external gas and expand. At this time, airbag 501 absorbs air from nozzle 505 through pipe 504. Gas from inlet 506 enters the interior of airbag 501 through nozzle 505 and pipe 504, creating negative pressure at inlet 506. At this time, debris inside the concave mold of lower mold 20 enters the interior of inlet 506 due to negative pressure and falls into collection box 507 through inlet 506 for collection.

[0038] Working principle: When using this switch panel punching device, a limit plate 403 and a spring 404 are set to fix the panel and prevent it from moving during punching. A pipe 504, a nozzle 505, a feed port 506 and a collection box 507 are set to facilitate the cleaning of the debris generated during punching, which increases the overall practicality.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
