Description

Technical Field

[0001] This utility model belongs to the field of power distribution cabinet production technology, and specifically relates to a power distribution cabinet plate cutting device. Background Technology

[0002] In the field of power distribution cabinet manufacturing, plate cutting is a key process.

[0003] Traditional power distribution cabinet plate cutting devices often suffer from unreasonable structural design and limited functionality. Some devices lack effective guiding mechanisms during plate transport, causing the plates to easily shift, severely affecting cutting accuracy and resulting in significant plate waste. Other devices have independent positioning and cutting functions, which not only increases equipment costs and space requirements but also makes operation cumbersome and production inefficient.

[0004] As the requirements for product quality and production efficiency in the power distribution cabinet manufacturing industry continue to increase, existing sheet metal cutting devices are no longer able to meet actual production needs. Therefore, another type of power distribution cabinet sheet metal cutting device is provided to solve the above-mentioned technical problems. Utility Model Content

[0005] In view of the shortcomings of the prior art described above, the purpose of this utility model is to provide a power distribution cabinet plate cutting device to solve the problems of existing power distribution cabinet plate cutting devices, which affect cutting accuracy, have independent positioning and cutting functions, and occupy a large space.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A power distribution cabinet plate cutting device includes a base frame, a lifting platform fixedly installed inside the base frame, and multiple driven rollers rotatably installed at equal intervals inside the base frame. Two protrusions are symmetrically fixedly installed on the upper surface of the base frame, and a drive mechanism is rotatably installed between the two protrusions. An inverted U-shaped lifting frame is fixedly installed on the upper surface of the base frame, the lifting frame is located to the right of the protrusions, and a positioning and cutting integrated mechanism is installed inside the lifting frame, located directly above the lifting platform. Three guide mechanisms with adjustable guide spacing are installed inside the base frame, one of the guide mechanisms is located to the left of the drive mechanism, and the other two guide mechanisms are located on the left and right sides of the lifting frame, respectively.

[0008] In the above technical solution, the guiding mechanism includes a square rod, which is fixedly installed in the seat and offset from the driven roller. Two square sleeve blocks are slidably sleeved on the outer surface of the square rod. A shaft is fixedly installed on the upper surface of each square sleeve block. A sleeve shaft is rotatably sleeved on the outer surface of each shaft. The lower surface of the sleeve shaft is on the same transverse plane as the upper surface of the driven roller. A tightening bolt is threaded through the upper surface of the shaft. The lower surface of the tightening bolt is in contact with the upper surface of the square rod, and a handle is welded and fixedly installed on the upper surface of the tightening bolt.

[0009] In the above technical solution, two retaining rings are fixedly installed on the outer surface of the shaft, and the two retaining rings are respectively located at the upper and lower ends of the sleeve shaft.

[0010] In the above technical solution, the positioning and cutting integrated mechanism includes two hydraulic telescopic rods, which are fixedly installed inside the hoisting frame. A tool hanging plate is fixedly installed between the lower surfaces of the two hydraulic telescopic rods, and a tool is fixedly installed on the lower surface of the tool hanging plate.

[0013] The present invention provides a power distribution cabinet plate cutting device, which, compared with the prior art, has the following advantages:

[0014] This invention features an adjustable guide mechanism that allows for flexible adjustment based on the width of the sheet material, precisely guiding the material and effectively preventing deviation during transport. This significantly improves cutting accuracy and reduces material waste. Furthermore, by integrating positioning and cutting functions into a single integrated positioning and cutting mechanism, the equipment structure is simplified, reducing space requirements.

[0020] 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.

[0021] In this embodiment, front, back, left, right, top, and bottom are... Figure 1 Describe the reference plane. See [link / reference] Figures 1-4 This utility model provides a technical solution:

[0022] A power distribution cabinet plate cutting device includes a base frame 1, a lifting platform 11 fixedly installed inside the base frame 1, and multiple driven rollers 12 rotatably installed inside the base frame 1 via bearings at equal intervals. Two protrusions 13 are symmetrically fixedly installed on the upper surface of the base frame 1, and a drive mechanism 2 is rotatably installed between the two protrusions 13. An inverted U-shaped lifting frame 14 is fixedly installed on the upper surface of the base frame 1, the lifting frame 14 is located to the right of the protrusions 13, and a positioning and cutting integrated mechanism 3 is installed inside the lifting frame 14. The positioning and cutting integrated mechanism 3 is located directly above the lifting platform 11. Three guide mechanisms 4 with adjustable guide spacing are installed inside the base frame 1. Any one of the guide mechanisms 4 is located to the left of the drive mechanism 2, and the other two guide mechanisms 4 are located on the left and right sides of the lifting frame 14, respectively.

[0023] The guiding mechanism 4 is used to position the power distribution cabinet panels during the conveying process, preventing them from shifting and ensuring stability and cutting accuracy during cutting. In actual panel cutting production, panels are prone to shifting during conveying due to various factors. Once shifted, it not only leads to a decrease in cutting accuracy but may also cause panel waste and equipment damage. This device, by incorporating the guiding mechanism 4, can precisely guide the panels, greatly reducing the risk of panel shifting and ensuring smooth cutting operations, providing a reliable guarantee for producing high-quality power distribution cabinet panels.

[0024] In use, the power distribution cabinet plate to be cut is placed on the driven roller 12 from the left. With the cooperation of the drive mechanism 2 and the driven roller 12, the power distribution cabinet plate is conveyed towards the positioning and cutting integrated mechanism 3. After being conveyed to the cutting position, the positioning and cutting integrated mechanism 3, together with the lifting platform 11, completes the cutting of the power distribution cabinet plate. After cutting, the uncut part of the power distribution cabinet plate is pushed to the right by the drive mechanism 2. The cut plate moves to the right under the push of the uncut plate, thus completing the cutting of the remaining part of the plate.

[0025] It should be noted that, in combination Figure 1 and Figure 4 As shown, the guide mechanism 4 includes a square rod 41, which is fixedly installed in the base frame 1 and offset from the driven roller 12. Two square sleeve blocks 42 are slidably sleeved on the outer surface of the square rod 41. A shaft 43 is welded and fixedly installed on the upper surface of each square sleeve block 42. A sleeve shaft 44 is rotatably sleeved on the outer surface of the shaft 43. The lower surface of the sleeve shaft 44 is on the same transverse plane as the upper surface of the driven roller 12. The two sleeve shafts 44 work together to provide precise guidance for the distribution cabinet plate between them. A tightening bolt 45 is threaded through the upper surface of the shaft 43. After the lower surface of the tightening bolt 45 is pressed against the upper surface of the square rod 41, the square sleeve block 42 is fixed. A handle 46 is welded and fixedly installed on the upper surface of the tightening bolt 45. By operating the handle 46, the tightening bolt 45 can be rotated, thereby completing the locking or unlocking operation of the square sleeve block 42.

[0026] By incorporating an adjustable square sleeve 42, the device can be flexibly adjusted to accommodate plates of varying widths during actual use, greatly enhancing its versatility and adaptability. Simultaneously, the design of the clamping bolt 45 and handle 46 makes operation more convenient, allowing workers to quickly adjust the guide mechanism 4 and improving work efficiency.

[0027] In practical use, the distance between the two square sleeves 42 can be adjusted after unlocking the fixed square sleeve 42 according to the width of the distribution cabinet plate to be cut, so as to adapt to the guiding work of distribution cabinet plates of different widths. This adjustable feature breaks the limitations of the traditional fixed guiding mechanism 4, enabling the device to meet diverse production needs. Whether it is a narrow plate or a wide plate, it can achieve precise guidance, further improving the utilization rate of the equipment and production efficiency.

[0028] In addition, to ensure the stability of the sleeve shaft 44 during rotation, two retaining rings 431 need to be welded and fixedly installed on the outer surface of the shaft 43. The two retaining rings 431 are located at the upper and lower ends of the sleeve shaft 44, respectively. The two retaining rings 431 can be used to limit the upper and lower positions of the sleeve shaft 44 and prevent it from moving up and down during rotation.

[0029] In addition, combined Figure 1 , Figure 2 and Figure 3 As shown, the positioning and cutting integrated mechanism 3 includes two hydraulic telescopic rods 31, which are fixedly installed inside the hoisting frame 14. A tool hanging plate 32 is fixedly installed between the lower surfaces of the two hydraulic telescopic rods 31. A tool 33 is fixedly installed on the lower surface of the tool hanging plate 32. Two positioning telescopic rods 34 are fixedly installed on both the left and right sides of the tool hanging plate 32. A pressure plate 35 is fixedly installed between the lower surfaces of the front and rear tool hanging plates 32. Two springs 36 are fixedly installed between the pressure plate 35 and the tool hanging plate 32. The springs 36 are located on the outside of the corresponding positioning telescopic rods 34.

[0030] When the positioning and cutting integrated mechanism 3, in conjunction with the lifting platform 11, cuts the power distribution cabinet material, the hydraulic telescopic rod 31 extends and drives the tool 33 downward through the tool lifting plate 32 to cut the power distribution cabinet material. During the cutting process, the pressure plate 35 is first driven downward by the tool lifting plate 32 to contact the power distribution cabinet material. The spring 36 then presses and positions the power distribution cabinet material, further improving the stability of the cutting process. This positioning-then-cutting working mode fully considers the importance of the material's stability during the cutting process. Through the elastic buffering and pressing effect of the spring 36, the vibration generated during the cutting process can be effectively absorbed, reducing damage to the material and the tool, and extending the service life of the equipment.

[0031] To improve the stability of the positioning and cutting integrated mechanism 3, two directional rods 321 need to be fixedly installed on the upper surface of the tool hanging plate 32. The directional rods 321 pass through the lifting frame 14 and are slidably connected to the lifting frame 14.

[0032] Finally, combining Figure 1As shown, the drive mechanism 2 includes a drive motor 21 fixedly mounted on the front surface of the base 1 and a drive roller 22 rotatably mounted between two protrusions 13. The drive motor 21 is a servo motor, and the front end of the drive roller 22 is fixedly connected to the output end of the drive motor 21 via a coupling. The drive roller 22 is a rubber roller. The drive mechanism 2, using a combination of a servo motor and a rubber drive roller 22, can provide a stable and adjustable driving force, precisely controlling the conveying speed and position of the sheet metal according to production needs. The rubber drive roller 22 has good friction, which can effectively prevent the sheet metal from slipping during conveying, ensuring the stability and accuracy of the sheet metal conveying.
