Description

Technical Field

[0001] This invention relates to the field of punching equipment technology, and in particular to a punching device for high-voltage power components. Background Technology

[0002] In the process of upgrading the power system towards high-end and intelligent systems, high-voltage power components, as the core basic components of high-voltage power supply systems, are widely used in transmission lines, power distribution equipment, and power terminal facilities at voltage levels of 10kV and above. Their processing quality directly determines the safety, stability, operational reliability, and service life of the power system. They play an irreplaceable role in ensuring the normal power supply for industrial production, urban infrastructure, and large public buildings. High-voltage power components cover a wide range, including busbar components such as copper and aluminum busbars, copper blocks in high-voltage switch boxes, insulator connection hardware, and tower connection components. During the assembly and use of these components, specific specifications and hole types of mounting holes or connection holes must be processed through punching technology to achieve precise docking, fixing, and conductive connection between components, meeting the assembly accuracy and electrical performance requirements of high-voltage power systems.

[0003] Chinese patent CN120772348A discloses a punching device for stainless steel parts. By driving the punch and grinding plate to reciprocate up and down, the hole wall can be ground multiple times. Through multiple grinding operations, the manual grinding process can be reduced, thus lowering labor costs.

[0004] The above-mentioned methods can reduce manual grinding, lower labor costs, and improve punching quality. However, high-voltage power components have higher requirements for punching quality. Without a stable and flexible fixation, the components may be bent and deformed during punching, resulting in poor punching quality. Metal chips are easily scattered during punching operations, posing safety hazards and potentially affecting the operator's real-time observation of the process. Furthermore, the lack of precise pre-pressure fixation around the punching position may cause edge warping. After punching, the workpiece is prone to sticking, making it difficult to remove the punch head, resulting in poor work efficiency and quality. Die-changing operations are cumbersome, with long working intervals, making it impossible to guarantee the continuity of punching operations and leading to low work efficiency. Summary of the Invention

[0005] To solve the above technical problems, the present invention provides the following technical solution: A punching device for high-voltage power components, comprising a workbench, a base fixedly connected to the top of the workbench, a punching device fixedly connected to the top of the base, a punching platform fixedly connected to the top of the workbench on one side of the base via a bracket, connecting brackets symmetrically fixedly connected to the top of the punching platform, a clamping device fixedly connected to the inner wall of the connecting brackets, an opening provided in the top of the punching platform between the connecting brackets, and a lower die box slidably connected to the top of the workbench below the punching platform. A collection box is slidably connected to one side of the punching table. Buffer pads are fixedly connected to the bottom diagonally of the workbench via brackets. The punching device includes a frame, with support plates fixedly connected to both sides of the frame. A fixed end of a punching cylinder is fixedly connected to the top of the support plate. The movable end of the punching cylinder passes through the top of the support plate and is fixedly connected to a connecting beam. A punching mechanism is fixedly connected to the bottom of the connecting beam. Linkage components are fixedly connected to both ends of the connecting beam. The linkage components are parallel linkage mechanisms. The middle of the linkage component's connecting rod is rotatably connected to the connecting bracket. The frame is fixedly connected to the top of the base.

[0006] Preferably, the lower mold box includes a box body, the top of the box body has a punched opening, the side of the box body has a discharge port, the inner walls of the discharge port are fixedly connected to both sides of the discharge port with inclined guide plates, the sides of the box body are fixedly connected to synchronous connecting rods, the portions of the sides of the box body above the synchronous connecting rods are fixedly connected to lifting plates, the bottom of the box body is fixedly connected to guide rods at opposite corners, one end of the synchronous connecting rod is fixedly connected to the end of the linkage assembly away from the connecting crossbeam, and the guide rod passes through the top of the worktable and is slidably connected to the worktable.

[0007] Preferably, the clamping device includes a ring frame with a placement groove at the top. Synchronous fixing components are rotatably connected to both sides of the inner wall of the ring frame. A guide shaft is passed through and fixedly connected to the side of the ring frame. A positive and negative ball screw is passed through and rotatably connected to the portion of the side of the ring frame away from the guide shaft. A handle is fixedly connected to one end of the positive and negative ball screw. A sliding plate is passed through and threadedly connected to the positive and negative ball screw. A clamping plate is fixedly connected to the top of the sliding plate. The side of the sliding plate is slidably connected to the guide shaft. Both the sliding plate and the clamping plate are provided with two sets of parallel... Symmetrically distributed on both sides of the ring frame, both sides of the ring frame are fixedly connected to the connecting bracket. The opening of the ring frame corresponds to the movable opening. The stamping cylinder drives the connecting beam to move the punching mechanism downward to perform the punching operation. At the same time, the linkage component pulls the synchronous connecting rod synchronously, causing the lower die box to move upward and the punching opening to move upward synchronously, forming a bidirectional stamping effect, reducing the deformation and cracking of the parts. The clamping device can put the parts into the placement slot. Turning the handle drives the positive and negative ball screws to rotate, driving the clamping plates to move towards each other, initially positioning the parts laterally, reducing the labor intensity of manual hand positioning.

[0008] Preferably, the synchronous fixing assembly includes a rotating plate, a fixing plate fixedly connected to the top side of the rotating plate, and first springs evenly fixedly connected to the bottom of the fixing plate. An elastic pad is fixedly connected to the end of the first spring away from the fixing plate. Guide grooves are evenly formed on the side of the rotating plate away from the fixing plate. A slider is slidably connected to the inner wall of the guide groove. A synchronous sliding rod is rotatably connected to the side of the slider away from the guide groove via a bracket. Both sides of the rotating plate are rotatably connected to the inner wall of the annular frame. The synchronous sliding rod passes through the top of the punching platform and is fixedly connected to the top of the lifting plate. When the punching device moves downward, the lower die box moves upward, causing the lifting plate to rise synchronously. The lifting plate pushes the synchronous slide bar to slide, and the linkage rotating plate drives the fixed plate to rotate towards the part. With the help of the first spring and elastic pad, the part is elastically fixed longitudinally. The synchronous fixation in both the horizontal and vertical directions can avoid the deformation and bending caused by the part shifting or uneven force during punching, thus improving the punching accuracy. The elastic structure can also buffer and protect against scratches and indentations on the surface of the part. After the punching waste falls into the box, it is guided by the inclined guide plate to enter the collection box from the discharge port. No manual cleaning is required. The collection box can be directly pulled out for processing without affecting subsequent operations.

[0009] Preferably, the punching mechanism includes a connecting cylinder, an mounting assembly fixedly connected to the top of the inner wall of the connecting cylinder, symmetrical sliding grooves on the side of the connecting cylinder, a connecting block slidably connected to the inner wall of the sliding groove, a first threaded groove and a second threaded groove respectively on one side of the inner wall of the sliding groove, a movable groove on one side of the inner wall of the connecting cylinder, the movable groove communicating with the first threaded groove, a second spring fixedly connected to one side of the inner wall of the movable groove, an adjusting rod fixedly connected to one end of the second spring, an adjusting screw threadedly connected through and to the side of the connecting block, the inner walls of both the first threaded groove and the second threaded groove being threadedly connected to the adjusting screw, a connecting ring fixedly connected to the bottom of the connecting block, and a series of evenly fixedly connected components at the bottom of the connecting ring. A buffer spring is provided, with a transparent protective cover fixedly connected to its bottom. A flexible annular pad is fixedly connected to the bottom of the transparent protective cover. A positioning slot is provided on the inner wall of the connecting cylinder. The top of the connecting cylinder is fixedly connected to the bottom of the connecting beam. The connecting block is fixed to the second threaded groove of the sliding groove by an adjusting screw. The transparent protective cover covers the punching head. When the punching mechanism is driven to move down by the punching cylinder, the flexible annular pad at the bottom of the protective cover first contacts the surface of the part. As the mechanism continues to move down, the buffer spring is compressed, and the flexible annular pad fits tightly against the part. This achieves pre-compression fixation, prevents the part from lifting off locally, and buffers vibration. At the same time, the transparent protective cover blocks metal debris generated by punching, preventing it from flying and injuring people, and does not affect the real-time observation of the punching situation.

[0010] Preferably, the mounting assembly includes a mounting base with a mounting slot at its bottom. A mounting post is slidably connected to the inner wall of the mounting slot. A connecting post is fixedly connected to the bottom of the mounting post. A punch head is fixedly connected to the bottom of the connecting post. A positioning rod is fixedly connected to the side of the connecting post. A limit groove is formed on the side of the mounting post. An unlocking groove is formed on one side of the inner wall of the mounting slot. An adjusting plate is rotatably connected to the inner wall of the unlocking groove. A first unlocking rod and a second unlocking rod are rotatably connected to both sides of the adjusting plate via brackets. A limit rod is fixedly connected to one end of the first unlocking rod, and the side of the limit rod is slidably connected to the inner wall of the limit groove. A transmission block is fixedly connected to one end of the second unlocking rod, and both sides of the transmission block are slidably connected to the inner wall of the unlocking groove. A positioning rod is fixedly connected to one side of the adjusting plate. A return spring is provided, with one end of the return spring away from the adjusting plate fixedly connected to one side of the inner wall of the unlocking groove. A positioning groove is provided on one side of the inner wall of the unlocking groove. The top of the mounting base is fixedly connected to the top of the inner wall of the connecting cylinder. Both sides of the positioning rod are slidably connected to the inner wall of the positioning slot. The inner wall of the positioning groove is slidably connected to the side of the adjusting rod. When changing punch heads of different specifications, loosen the adjusting screw, pull the connecting block to move the transparent protective cover to the top of the sliding groove, and screw the adjusting screw into the first threaded groove for fixation. At this time, the protective cover does not affect the disassembly and assembly of the punch head, and the adjusting screw will squeeze the structure to unlock the punch head limit, so the old punch head can be directly removed. When replacing the new punch head, align the mounting post with the slot and insert it. Ensure the positioning rod is installed accurately, then move the protective cover down and fix the adjusting screw to complete the punch head limit locking simultaneously.

[0011] The beneficial effects of the technical solution provided by this invention include: 1. This punching equipment for high-voltage power components, through bidirectional punching and lateral positioning, improves punching efficiency while ensuring punching quality. Bidirectional punching causes the punching mechanism and the lower die box to move synchronously in opposite directions, resulting in uniform force distribution, effectively improving punching accuracy, reducing punching impact, and minimizing deformation and cracking of high-voltage power components due to uneven force distribution, thus ensuring punching quality. Lateral clamping and positioning, driven by positive and negative ball screws, allows for rapid initial positioning of components, replacing manual hand-held positioning, reducing operator workload, minimizing positioning time, accelerating the punching operation, and achieving simultaneous improvement in quality and efficiency.

[0012] 2. This punching equipment for high-voltage power components ensures punching quality through bidirectional linkage elastic fixing. The synchronous fixing component is activated in conjunction with the downward pressing action of the punching mechanism, forming a bidirectional elastic fixing with the clamping plate below. This achieves stable positioning of the components from multiple directions, preventing punching deviation. At the same time, the elastic buffer structure prevents scratches and indentations on the surface of the components, ensuring the integrity of the appearance and punching accuracy. Punching waste automatically falls into the box and is guided to the collection box by the inclined guide plate. No manual shutdown for cleaning is required, avoiding waste accumulation that may affect subsequent operations. The pull-out collection box facilitates quick and unified waste disposal, reducing workload and ensuring continuous and efficient punching operations, thereby improving punching quality and work efficiency.

[0013] 3. This punching equipment for high-voltage power components utilizes protective buffering and precise pre-pressure. During punching operations, a transparent protective cover encloses the punch head, and a flexible annular pad contacts and pre-presses the component to prevent it from warping during punching. A buffer spring reduces vibration transmission, preventing component deformation and blocking metal debris from splashing without affecting real-time observation, ensuring punching accuracy and operational safety. Furthermore, the protective and unlocking states can be easily switched according to actual punching needs and punch head replacement requirements without additional steps. After punching, the transparent protective cover and flexible annular pad gently push out the punched component, preventing adhesion to the punch head and further improving punching quality and efficiency.

[0014] 4. This punching equipment for high-voltage power components features convenient mold changing and precise installation. When changing the punching head, no additional tools are needed. Simply move the transparent protective cover to expose the punching head for easy removal, and simultaneously unlock and fix the punching head. The process is smooth and seamless, allowing for quick switching between different specifications of punching heads to meet diverse hole diameter requirements. This significantly reduces mold changing time and improves work continuity. During installation, the positioning rod and positioning slot work together to ensure accurate installation of the punching head, avoiding impact on punching quality due to installation deviations. At the same time, the convenient mold changing design reduces work intervals, improves the overall continuity of punching operations, and further enhances punching efficiency.

Detailed Implementation

[0017] For the first embodiment, please refer to... Figures 1-4This invention provides a punching device for high-voltage power components. Through the cooperation of the punching device 3 and the lower die box 8, while the punching cylinder 33 drives the connecting beam 34 to move the punching mechanism 35 downwards for punching, the linkage component 36 simultaneously pulls the synchronous connecting rod 85, causing the lower die box 8 to move upwards. The upward movement of the lower die box 8 synchronously moves the punching opening 82 upwards, creating a bidirectional punching effect. This not only improves the punching accuracy but also effectively reduces the impact force on the high-voltage power components during the punching process, minimizing deformation caused by uneven stress on the components. In the event of deformation or cracking, the clamping device 6 allows the high-voltage electrical components to be placed in the placement slot 62 of the ring frame 61. Rotating the handle 66 drives the forward and reverse ball screws 65 to rotate, which in turn drives the two sets of sliding plates 67 to slide towards each other along the guide shaft 64. This causes the clamping plates 68 on both sides to move synchronously, achieving initial lateral positioning of the components. This reduces the labor intensity of manual hand-held positioning and punching. After positioning, when the punching device 3 moves downwards, the lower die box 8 moves upwards, causing the lifting plate 86 to move upwards synchronously. The lifting plate 86 pushes the synchronous slide rod 637 upwards. 637, through the sliding of slider 636 within guide groove 635, drives rotating plate 631 to rotate around the inner wall of annular frame 61, causing fixed plate 632 at the top of rotating plate 631 to rotate towards the accessory. This, combined with the first spring 633 and elastic pad 634, achieves elastic fixation of the accessory longitudinally, providing synchronous fixation in both the lateral and longitudinal directions. This prevents accessory displacement during punching and also prevents deformation and bending caused by unstable fixation and uneven force on both sides during punching, further improving punching accuracy. Furthermore, the combination of elastic pad 634 and first spring 633 also enhances the fixing... The timed buffering mechanism prevents hard clamps from scratching or indenting the surface of the components, ensuring the appearance integrity of the high-voltage power components. After punching, the waste material falls directly into the housing 81, and then slides out from the discharge port 83 through the inclined guide plate 84, falling directly into the collection box 9 on the side. There is no need for manual cleaning of the waste material inside the housing 81, which reduces the workload of the operators and avoids the accumulation of waste material affecting the subsequent punching operation. When it is necessary to uniformly process the waste material in the collection box 9, simply pull the collection box 9 out from the top of the workbench 1.

[0018] For the second embodiment, please refer to... Figures 1-10By providing a punching mechanism 35, during punching operations, the connecting block 354 is located on one side of the second threaded groove 356 within the sliding groove 353, and the connecting block 354 is threadedly fixed to the second threaded groove 356 via the adjusting screw 3510. At this time, the transparent protective cover 3513 is located outside the punching head 3525, enclosing the punching head 3525 inside. When the punching cylinder 33 drives the connecting beam 34 to move the punching mechanism 35 downward, the flexible annular pad 3514 at the bottom of the transparent protective cover 3513 will first contact the surface of the high-voltage power accessory. As the punching mechanism 35 continues to move downward, the buffer spring 3512 is compressed, and the flexible annular pad 3514 tightly adheres to the surface of the accessory, which can pre-press and fix the surface of the accessory before punching, avoiding... During the punching process, the parts partially lift up, which also acts as a buffer and protector, reducing the transmission of vibration generated when the punch head 3525 is pressed down to other parts of the parts. At the same time, the transparent protective cover 3513 can effectively block metal debris generated during the punching operation, preventing debris from flying and injuring people, without affecting the real-time observation of the punching process. When it is necessary to change to a different size punch head 3525, simply loosen the adjusting screw 3510, pull the connecting block 354 to move the transparent protective cover 3513 upward to the top of the sliding groove 353, and screw the adjusting screw 3510 into the first threaded groove 355 to complete the fixation. At this time, the transparent protective cover 3513 moves up to a position that does not affect the disassembly and assembly of the punch head 3525, and as the adjusting screw 3510 is screwed in... When the first threaded groove 355 enters the movable groove 357, the adjusting screw 3510 compresses the second spring 358, causing the adjusting rod 359 to slide into the positioning groove 35215. The end of the adjusting rod 359 pushes the transmission block 35213 to slide in the unlocking groove 3528. The transmission block 35213 pushes the adjusting plate 3529 to rotate through the second unlocking rod 35211. On the other side of the adjusting plate 3529, the first unlocking rod 35210 drives the limiting rod 35212 to disengage from the limiting groove 3527, releasing the limiting fixation on the mounting post 3523. At this time, the punch head 3525 can be pulled down directly, causing the mounting post 3523 to be pulled out from the mounting slot 3522, completing the disassembly of the old punch head 3525 and replacing it with a new punch head 3525. At 25 o'clock, align the mounting post 3523 with the mounting slot 3522 and insert it. Simultaneously, engage the positioning rod 3526 in the positioning slot 3515 on the inner wall of the connecting cylinder 351, ensuring the punch head 3525 is accurately positioned. After inserting the mounting post 3523 into the mounting slot 3522 and aligning the positioning groove 35215 with the movable groove 357, loosen the adjusting screw 3510 and allow the connecting block 354 to slide back into the second threaded groove 356 within the sliding groove 353. Secure it to the second threaded groove 356 using the adjusting screw 3510. During this process, after the adjusting rod 359 loses the pushing force of the adjusting screw 3510, it is pulled back to its initial position by the restoring force of the second spring 358, and the transmission block 35213 loses its thrust.The adjusting plate 3529 rotates in the reverse direction under the reset action of the return spring 35214, driving the limiting rod 35212 to re-engage into the limiting groove 3527 via the first unlocking rod 35210, thus completing the limiting and fixing of the newly installed post 3523. The entire replacement process requires no additional tools; the unlocking and fixing of the punch head 3525 can be completed simultaneously with the movement of the transparent protective cover 3513. The steps are smooth and seamless, the operation is convenient and efficient, and it can quickly switch between different specifications of punch heads 3525 to meet the punching needs of different hole diameters, improving the efficiency of punching operations.
