Description

Technical Field

[0001] The utility model relates to the technical field of sheet metal processing, and specifically relates to a sheet metal processing device for electrical cabinets. Background Technique

[0002] An electrical cabinet is a cabinet made of steel materials to protect components from normal operation. Electrical cabinets are widely used in the chemical industry, environmental protection industry, power system, metallurgical system, industry, nuclear power industry, fire safety monitoring, transportation industry, etc. Electrical cabinets need to be processed by welding and assembling multiple sheet metals.

[0003] A series of preparatory work needs to be carried out before the sheet metal is processed into an electrical cabinet. These pretreatment steps are designed to ensure that the surface of the sheet metal is clean and flat. The treatment usually includes cleaning the surface of the sheet metal to remove dust, dirt, and grease; sanding the surface to remove uneven parts.

[0004] When the existing sheet metal is polished, it is necessary for workers to use a clamping plate to fix the sheet metal. However, during the process of clamping and fixing the sheet metal, due to the high hardness of the sheet metal, it is not easy to unfold and lay flat on the operating table, and it is easy to shift during grinding, affecting the flatness of the sheet metal. At the same time, workers use a sander to polish the surface of the sheet metal, which is time-consuming and laborious, and the processing efficiency is low. A large amount of debris generated falls into the gaps of the operating table and is not easy to clean. Content of the Utility Model

[0005] Based on this, the purpose of the utility model is to provide a sheet metal processing device for electrical cabinets to solve the technical problems proposed in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A sheet metal processing device for electrical cabinets, including an operating table and a connecting frame. One end of the connecting frame is movably installed with a connecting rod, and both ends of the connecting rod are movably installed with extrusion rods. One end of the extrusion rod is movably installed with a first clamping plate, and a spring is connected between the extrusion rod and the first clamping plate. Limiting grooves matched with the extrusion rods are opened at both ends of the connecting frame, guiding grooves matched with the first clamping plate are opened at both ends of the connecting frame, and a second clamping plate matched with the first clamping plate is movably installed at one end of the guiding groove.

[0007] By adopting the above technical solution, during the downward movement of the extrusion rod, the first clamping plate cooperates with the second clamping plate to clamp and fix both ends of the sheet metal. At the same time, the extrusion rod is limited by the limiting groove, so that both ends of the clamped sheet metal are stretched outwards along the guiding groove by the first clamping plate and the second clamping plate, enabling the sheet metal to be fully unfolded and laid flat on the operating table, thus solving the problem that the sheet metal is not easy to unfold and lay flat on the operating table and is easy to shift during grinding, affecting the flatness of the sheet metal, simplifying the operation steps, and facilitating the use of workers.

[0008] The utility model is further arranged such that first guide rails are fixedly installed at both ends of the operating table, and a second guide rail is movably installed at one end of the first guide rail. A support leg is fixedly installed at one end of the operating table, and multiple groups of support legs are provided. A control panel is fixedly installed at one end of the operating table.

[0009] By adopting the above technical solution, by installing the support legs, the device obtains better support force and is more stable when the device is running and in use.

[0010] The utility model is further arranged such that a dust removal box is movably installed at one end of the second guide rail, a fixed box is movably installed at one end of the dust removal box, a hydraulic rod is installed between the dust removal box and the fixed box. Guide rods are fixedly installed at both ends of the fixed box, and a connecting plate is movably installed at one end of the guide rod. A grinding plate is fixedly installed at one end of the connecting plate, and dust suction holes are formed at one end of the grinding plate.

[0011] By adopting the above technical solution, by forming the dust suction holes, the dust suction holes are evenly distributed on the surface of the grinding plate, so that the adsorption force generated by the rotation of the fan blades is evenly distributed on the sheet metal surface in contact with the grinding plate, thereby increasing the dust suction range and chip removal effect and improving the working efficiency.

[0012] The utility model is further arranged such that a driving motor is fixedly installed at one end of the dust removal box, and a limiting wheel disc matched with the connecting plate is fixedly installed at the output end of the driving motor. The fixed box and the connecting rod are connected through a fixed sleeve.

[0013] By adopting the above technical solution, by installing the limiting wheel disc, under the limiting action of the limiting wheel disc on the connecting plate, the rotation is converted into linear motion, thereby reducing energy loss, improving the stability of the device, and improving the sheet metal processing quality to a certain extent.

[0014] The utility model is further arranged such that the connecting plate and the dust removal box are connected through a dust suction pipe. A rotating shaft is movably installed at one end of the dust removal box, and a fan blade is fixedly installed at one end of the rotating shaft. The rotating shaft and the driving motor are connected through a belt.

[0015] By adopting the above technical solution, through the connection of the belt between the rotating shaft and the driving motor, the various parts of the device can be better linked, and the structure composition of the device is improved.

[0016] In summary, the utility model mainly has the following beneficial effects:

[0017] 1. The utility model is provided with a connecting frame, a pressing rod, a first clamping plate, a second clamping plate, etc. The hydraulic rod drives the fixed box to move vertically downward, so that the fixed box drives the connecting rod to move through the fixed sleeve, and the pressing rod pushes the first clamping plate to move through the compression spring. When the pressing rod moves downward, the first clamping plate cooperates with the second clamping plate to clamp and fix both ends of the sheet metal. At the same time, the pressing rod is limited by the limiting groove, so that the first clamping plate and the second clamping plate stretch the clamped ends of the sheet metal outward along the guiding groove, making the sheet metal fully unfold and lay flat on the operating table, thus solving the problem that the sheet metal is not easy to unfold and lay flat on the operating table, and is easy to shift during grinding, affecting the flatness of the sheet metal, simplifying the operation steps, and facilitating the use of the staff.

[0018] 2. The utility model is provided with a dust suction hole, a dust suction pipe, a fan blade, etc. The driving motor drives the limiting wheel disc to rotate at a high speed, so that the connecting plate makes a high-speed reciprocating motion along the guiding rod under the limiting action of the limiting wheel disc, so that the grinding plate grinds and polishes the sheet metal. At the same time, the driving motor drives the fan blade to rotate at a high speed through the belt-driven rotating shaft, so that the dust removal box generates an adsorption force, and sucks the generated debris, dust and impurities into the dust removal box through the dust suction pipe from the dust suction hole for unified collection operation, thus simplifying the operation steps, improving the work efficiency, ensuring the cleanliness of the device, improving the practicability, and reducing the work intensity of the staff to a certain extent.

The embodiments described below by referring to the accompanying drawings are exemplary and are only used to explain the present utility model, and should not be construed as a limitation to the present utility model.

[0025] Next, according to the overall structure of the present utility model, its embodiments will be described.

[0026] An electrical cabinet sheet metal processing device, as Figures 1-4 shown, includes an operating table 1 and a connecting frame 7. One end of the connecting frame 7 is movably installed with a connecting rod 9, and both ends of the connecting rod 9 are movably installed with extrusion rods 14. One end of the extrusion rod 14 is movably installed with a first clamping plate 16, and a spring 15 is connected between the extrusion rod 14 and the first clamping plate 16. Limiting grooves 11 matching the extrusion rods 14 are opened at both ends of the connecting frame 7, and guiding grooves 12 matching the first clamping plate 16 are opened at both ends of the connecting frame 7. And a second clamping plate 17 matching the first clamping plate 16 is movably installed at one end of the guiding groove 12. The extrusion rod 14 pushes the first clamping plate 16 to move through the extrusion spring 15, so that when the extrusion rod 14 moves downward, the first clamping plate 16 cooperates with the second clamping plate 17 to clamp and fix both ends of the sheet metal. At the same time, the extrusion rod 14 is limited by the limiting groove 11, so that both ends of the clamped sheet metal by the first clamping plate 16 and the second clamping plate 17 are stretched outwards along the guiding groove 12, so that the sheet metal is fully unfolded and laid flat on the operating table 1.

[0027] Please refer to Figure 1 , first guide rails 4 are fixedly installed at both ends of the operating table 1, and a second guide rail 5 is movably installed at one end of the first guide rail 4. A support foot 2 is fixedly installed at one end of the operating table 1, and the support foot 2 is provided in multiple groups. A control panel 3 is fixedly installed at one end of the operating table 1. By installing the support foot 2, the device obtains better support force and is more stable when the device is running and in use.

[0028] Please refer to Figure 4 , a dust removal box 8 is movably installed at one end of the second guide rail 5. A fixed box 6 is movably installed at one end of the dust removal box 8, and a hydraulic rod 19 is installed between the dust removal box 8 and the fixed box 6. Guide rods 21 are fixedly installed at both ends of the fixed box 6, and a connecting plate 22 is movably installed at one end of the guide rod 21. A polishing plate 13 is fixedly installed at one end of the connecting plate 22, and a dust suction hole 18 is opened at one end of the polishing plate 13. By opening the dust suction holes 18, the dust suction holes 18 are evenly distributed on the surface of the polishing plate 13, so that the adsorption force generated by the rotation of the fan blades 25 is evenly distributed on the sheet metal surface in contact with the polishing plate 13, thereby increasing the dust suction range and chip removal effect and improving work efficiency.

[0029] Please refer to Figure 4, one end of the dust removal box 8 is fixedly installed with a driving motor 20, and the output end of the driving motor 20 is fixedly installed with a limiting wheel disc 26 that cooperates with the connecting plate 22. The fixed box 6 and the connecting rod 9 are connected through a fixed sleeve 10. By installing the limiting wheel disc 26, the rotation is converted into linear motion under the limiting action of the limiting wheel disc 26 on the connecting plate 22, thereby reducing energy loss, improving the stability of the device, and improving the quality of sheet metal processing to a certain extent.

[0030] Please refer to Figure 4 , the connecting plate 22 and the dust removal box 8 are connected through a suction pipe 23. One end of the dust removal box 8 is movably installed with a rotating shaft 24, and one end of the rotating shaft 24 is fixedly installed with a fan blade 25. The rotating shaft 24 and the driving motor 20 are connected through a belt. By connecting the rotating shaft 24 and the driving motor 20 through a belt, the various parts of the device can be better linked, and the structure of the device can be improved.

[0031] The working principle of the present utility model is as follows: When in use, first place the sheet metal to be processed on the operating table 1, and then adjust the cooperation between the second guide rail 5 and the first guide rail 4 to move to the required grinding position through the control panel 3. At this time, the hydraulic rod 19 drives the fixed box 6 to move vertically downward, so that the fixed box 6 pulls the connecting rod 9 to move through the fixed sleeve 10, so that the pressing rod 14 pushes the first clamping plate 16 to move through the compression spring 15, so that the first clamping plate 16 cooperates with the second clamping plate 17 to clamp and fix both ends of the sheet metal during the downward movement of the pressing rod 14. At the same time, the pressing rod 14 is limited by the limiting groove 11, so that the first clamping plate 16 and the second clamping plate 17 stretch the clamped ends of the sheet metal outward along the guide groove 12, so that the sheet metal is fully unfolded and laid flat on the operating table 1. Then start the driving motor 20, so that the driving motor 20 drives the limiting wheel disc 26 to rotate at a high speed, so that the connecting plate 22 makes a high-speed reciprocating motion along the guide rod 21 under the limiting action of the limiting wheel disc 26, so that the grinding plate 13 grinds and polishes the sheet metal. At the same time, the driving motor 20 drives the fan blade 25 to rotate at a high speed through the belt transmission of the rotating shaft 24, so that the dust removal box 8 generates an adsorption force, and the debris, dust and impurities generated by grinding are sucked into the dust removal box 8 through the suction pipe 23 from the suction holes 18 for unified collection operation. After the grinding of the required grinding position of the sheet metal is completed, it is okay.
