Description

Technical Field

[0001] This utility model relates to the field of power distribution cabinet processing technology, specifically a power distribution cabinet punching processing equipment. Background Technology

[0002] As one of the important pieces of equipment in the power system, the distribution cabinet is used to distribute, control and protect electrical energy. In the manufacturing process of the distribution cabinet, punching is a key process. Its quality and efficiency directly affect the overall performance and production cycle of the distribution cabinet. The accuracy of punching determines the installation accuracy and stability of the internal components of the distribution cabinet, which in turn affects the operational reliability of the power system. For example, if the punching position is deviated by a large margin, it may lead to the inaccurate installation of electrical components, or the connection after installation may be loose, resulting in safety hazards such as loosening and arcing during operation.

[0003] An investigation revealed that a Chinese utility model discloses a punching device for sheet metal processing of power distribution cabinet panels (Publication No.: CN221848380U). The device includes a punching platform with a punching machine on its surface, a chute and a discharge port within the punching platform, a slide block within the chute, a collection hole and a collection trough within a truncated cone, a flexible hose with a guide tube on its surface, and a filter plate and guide tube on the surface of the collection machine. The beneficial effects are: the truncated cone absorbs metal powder from the top of the power distribution cabinet panel, preventing the powder from dispersing into the air; the flexible hose transports the metal powder; the collection machine absorbs the powder promptly; the filter plate guides the waste material, preventing blockages; the collection box stores the metal powder and waste material; and the slide block ensures the stability of the collection box structure.

[0004] While the aforementioned patent achieves the function of storing metal powder and waste through the setting of the collection machine, and the slide ensures the stability of the collection box structure, the large number and varying positions of the holes on the distribution cabinet mean that punching from a single angle is far from meeting the actual installation and usage requirements. This is because the distribution cabinet needs to accommodate various electrical components, and the installation methods and wiring routes of these components are different, requiring the cabinet panel to have holes in different positions to match them. Punching from a single angle will inevitably lead to some components not being able to be installed smoothly, or the wiring layout being obstructed, affecting the overall functionality and stability of the distribution cabinet.

[0005] Therefore, this utility model provides a punching equipment for power distribution cabinets to solve the above problems. Utility Model Content

[0006] (a) Technical problems to be solved

[0007] This utility model provides a punching equipment for power distribution cabinets, which aims to solve the problems mentioned in the background art.

[0008] (II) Technical Solution

[0026] 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.

[0027] This utility model provides a punching processing equipment, such as Figures 1 to 5 As shown, the device includes a motor back box 1. Locking blocks 2 are bolted to the top and bottom of the front of the motor back box 1. A synchronous pulley 3 is movably connected to the center of one side surface of the locking block 2. A guide rail 4 is fixedly installed between the two synchronous pulleys 3 near the motor back box 1. A slider 5 is slidably engaged on one side surface of the guide rail 4. A connecting plate 6 is bolted to one side of the slider 5. A fixing plate 7 is bolted to one side of the connecting plate 6. The fixing plate 7 and the slider 5 are placed horizontally. A limiting plate is provided on the top of one side surface of the fixing plate 7. A support plate 8 is bolted to one side of the fixing plate 7. One side of the support plate 8 is connected to the fixing plate 7 through a hole. The plates 7 are connected together. The side of the support plate 8 away from the hole has an arc-shaped groove 801. The inner arc surface of the arc-shaped groove 801 has a rack 802. The inner arc surface of the arc-shaped groove 801 is slidably engaged with a gear tooth 9. The outer arc surface of the gear tooth 9 is meshed with the rack 802. A shaft 901 is fixedly installed in the middle of one side surface of the gear tooth 9. A hinge plate 10 is fixedly installed at one end of the shaft 901 on one side. A threaded hole is opened on the end face of the hinge plate 10 facing the shaft 901. A connecting base 11 is fixedly installed on the hinge plate 10 through the threaded hole on one side. A drive motor 12 is connected through the upper surface of the connecting base 11.

[0028] The motor is installed inside the motor housing 1, with one end fixedly connected to the synchronous pulley 3. When the motor is powered on and started, it drives the synchronous pulley 3 to rotate by its own torque output, thereby driving the synchronous belt sleeved on the surface of the synchronous pulley 3 to rotate smoothly. A connecting plate 6 is installed on the synchronous belt, and the connecting plate 6 is fixedly connected to the slider 5 that moves smoothly on the guide rail 4. In this way, as the synchronous belt moves steadily along a predetermined trajectory, the connecting plate 6 can move up and down within the path defined by the guide rail 4. The front end of the connecting plate 6 is connected to a support plate 8. The support plate 8 is an irregular plate with an arc-shaped profile at the bottom. An arc-shaped groove 801 is opened on the bottom surface, and a rack 802 is installed inside the arc-shaped groove 801. The rack 802 provides meshing space when the gear teeth 9 interact with it, ensuring that the gear teeth 9 can mesh and abut against each other under normal conditions without moving freely inside the arc groove 801, thus improving the reliability and stability of the connection between the two. Especially when it is necessary to flexibly change and adjust the drilling position in the front connecting base 11, the gear teeth 9 can slide along the inner wall of the arc groove 801 to be positioned to the desired ideal position. After the position is properly adjusted, the entire device is locked in the current state and kept fixed by tightening the nut on the adjusting shaft 901. Moreover, thanks to the connection between the teeth, even if vibration occurs during the punching process, it can effectively avoid loosening, displacement and other adverse conditions caused by vibration.

[0029] One end of the drive motor 12 extends through the connecting base 11 and is fixedly mounted with an upper bushing 13. The inner arc surface of the upper bushing 13 is movably connected to a punch connecting rod 14. The lower surface of the upper bushing 13 is provided with a punch guide sleeve 15. The outer arc surface of the punch guide sleeve 15 is fitted with a spring 16. One end of the spring 16 is fixedly mounted with a lower bushing 17. The lower surface of the lower bushing 17 is fixedly mounted with a guide sleeve seat 18. The lower surface of the guide sleeve seat 18 is connected through a die sleeve 19. The die sleeve 19 is connected to the lower bushing 17. A sealing ring 20 is provided at the connection between the die sleeve 19 and the lower bushing 17. The outer arc surface of the die sleeve 19 is provided with a protrusion 191. A guide groove 192 is provided between the protrusions 191. The guide groove 192 is adapted to the punch connecting rod 14. The inner arc surface of the die sleeve 19 is movably connected with a protective sleeve 21. The protective sleeve 21 is placed on the outer arc surface of the punch connecting rod 14.

[0030] In the critical process of punching, the punching stage is prone to causing the tricky problem of waste chips or aluminum wires flying everywhere. This not only makes the work area messy, but also adds a lot of inconvenience to the subsequent material recycling. Therefore, a guide sleeve seat 18 is installed at the bottom of the punch connecting rod 14. The lower surface of the guide sleeve seat 18 is stably connected to the die sleeve 19 by the lower bushing 17. The outer arc surface of the die sleeve 19 is provided with protrusions 191. Guide grooves 192 are provided between each pair of these protrusions 191. When the punch connecting rod 14 punches downward, the aluminum wires generated will rebound upward under the impact force. At this time, the protective sleeve 21 can concentrate and guide the upward rebounding aluminum wires smoothly into its internal space, avoiding aluminum wires flying. As the punching operation continues, the length of the aluminum wires in the protective sleeve 21 gradually increases. Due to the limited space at the bottom, the aluminum wires will be embedded into the pre-opened guide grooves 192, achieving orderly storage and effectively avoiding the situation of aluminum wires flying around.

[0031] Meanwhile, the outer protective sleeve 21 ensures that it will not obstruct the normal punching operation of the punch rod 14 throughout the punching process. On the contrary, thanks to the connection of the top spring 16, when the punch rod 14 initially contacts the cabinet plate, the protective sleeve 21 can cover the hole to be punched, forming the first protective barrier. Then, when the punch rod 14 continues to penetrate deeper into the hole, the protective sleeve 21 will only compress the spring 16, but it will still be placed around the hole, continuing to play a protective role, ensuring the smooth progress of the punching operation in all aspects, preventing waste chips from flying and ensuring that the punching is not affected.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
