Description

Technical Field

[0001] This application relates to the field of busbar processing technology, and in particular to a CNC equipment for automatic punching, shearing and bending of busbars in busbars. Background Technology

[0002] Busbar trunking is an indispensable power distribution equipment in power transmission systems. The processing quality of its core conductive component—the busbar (copper or aluminum)—directly affects the safety and reliability of the entire power transmission and distribution system. In the electrical complete equipment manufacturing industry, busbars typically require multiple processes such as punching, shearing, and bending to be formed into the final product.

[0003] Currently, busbar processing is generally carried out using busbar processing machines. Although existing busbar processing equipment has processing units such as punching, shearing, and bending, each processing step is relatively independent. Material transfer between different workstations requires manual assistance or additional conveying devices, making it difficult to further improve processing efficiency. Meanwhile, during punching and shearing, copper and aluminum shavings and metal impurities easily adhere to the surface of the punching and shearing head. If not cleaned in time, this not only affects the accuracy and hole quality of subsequent punching and shearing but also accelerates the wear of the punching and shearing head and shortens the mold's lifespan. In existing technologies, cleaning the punching and shearing head mostly relies on manual operation after machine shutdown, which is inefficient and poses safety hazards. Therefore, this paper proposes an integrated CNC machine for automatic punching, shearing, and bending of busbar trunking to solve the above problems. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this application provides an integrated CNC equipment for automatic punching, shearing, and bending of busbar trunking, which has advantages such as self-cleaning and protection function of the punching and shearing head, thus solving the problem of inconvenient cleaning of the punching and shearing head mentioned above.

[0005] This application provides an integrated CNC equipment for automatic punching, shearing, and bending of busbar trunking, which adopts the following technical solution:

[0006] An integrated CNC equipment for automatic punching, shearing and bending of busbar trunking includes an integrated CNC equipment consisting of a frame, a base, a material conveyor, a material bundler, a bending structure and a punching and shearing structure. The bending structure is located at the output end of the material bundler, and the punching and shearing structure is located on one side of the material bundler.

[0007] The punching and shearing structure includes a slide block, a punching and shearing head, and a scraper sleeve. The slide block is provided with a linkage component connected to the scraper sleeve. One side of the slide block is provided with an abutment plate that abuts against the linkage component. The inner side of the scraper sleeve is provided with a scraping groove that matches the punching and shearing head. When the slide block retracts, the scraper sleeve moves upward through the abutment of the linkage component and the abutment plate. At this time, the scraping groove scrapes material from the punching and shearing head, and the scraper sleeve can shield and protect the punching and shearing head.

[0008] The punching and shearing structure also includes a pressurizing component and a valve pipe. The valve pipe is installed between the pressurizing component and the scraper sleeve. When the scraper sleeve cleans the punching and shearing head, the pressurizing component also pressurizes and blows air to further enhance the cleaning effect. The linkage component is also used in conjunction with the pressurizing component.

[0009] Optionally: the linkage component includes a lifting plate, one end of which is rotatably mounted with a roller, the roller rollingly engaging with the outer surface of the abutment plate, a pull rod fixed to the outer wall of the scraper sleeve is mounted on the outer wall of the lifting plate, and an inclined connecting rod is hinged between the lifting plate and the slide block.

[0010] Optionally, the linkage assembly further includes a rotating shaft connected to the end of the roller, with an eccentric wheel fixed at the other end of the rotating shaft. When the slide retracts, the roller contacts the abutment plate first. As the slide continues to retract, the slide will squeeze the connecting rod, causing it to rotate and push the lifting plate upward, thereby driving the scraper sleeve to move. At the same time, the roller drives the eccentric wheel to rotate, driving the pressurization assembly to further improve the cleaning and protection of the punching shear head.

[0011] Optional: A collection box is snapped onto the bottom side of the scraper sleeve to collect impurities from the scraper sleeve; a nozzle is installed at one end of the valve tube and the nozzle is fixed inside the scraper sleeve; there are two valve tubes, and the two valve tubes are connected.

[0012] Optionally, the pressurization assembly includes a pressurization cylinder with a hollow interior, a pressurization piston that is slidably sealed inside the pressurization cylinder, and a return spring that is wound around and installed outside the pressurization piston, wherein one of the valve tube ends is fixed to and communicates with the pressurization cylinder.

[0013] Optionally: one end of the booster piston extends to the outside of the booster cylinder, and the end extending outside the booster cylinder is equipped with an abutment block that abuts against the eccentric wheel, and the booster cylinder is fixed to the outer wall of the lifting plate.

[0014] Optionally: The scraper sleeve is provided with a lubricating component for use in lifting. The lubricating component includes a bonding plate, a guide plate one, and a guide plate two. The guide plate one is fixed to the top side of the bonding plate, and the guide plate two is fixed to the bottom side of the slide block. The guide plate one and the guide plate two are interference fit.

[0015] Optionally, the lubricant also includes a guide rod fixed to one side of the bonding plate. The guide rod passes through the inside of the scraper sleeve, and a second return spring is wound around the outer surface of the guide rod. When the scraper sleeve moves upward, the bonding plate and the punching head are pressed together by the interference fit between the first guide plate and the second guide plate, thereby achieving lubrication of the outer surface of the punching head.

[0016] Optionally, the bending structure includes a lifting platform, a hydraulic telescopic rod, a center seat, a rotating seat, a drive assembly, two limiting clamps, and a bending component. The lifting platform is slidably mounted on the side wall of the machine base, the hydraulic telescopic rod is fixed to the top side of the frame, and the output end of the hydraulic telescopic rod is fixed to the bottom side of the lifting platform. The rotating seat is rotatably mounted on the outer surface of the center seat, and the two limiting clamps are slidably mounted on the top side of the center seat. The drive assembly includes a drive motor and a transmission gear. The drive motor is mounted on the lifting platform, and the transmission gear is located on the output shaft of the drive motor and outside the rotating seat.

[0017] Optionally: The bending component includes a mold base with a flange mounted on the top side of the rotating seat. The mold base has several annularly distributed workpiece slots inside. Molds are detachably installed inside the several workpiece slots. An abutment wheel is provided on one side of the mold. An adjusting bolt penetrating the interior of the mold base is installed on one side of the abutment wheel.

[0018] In summary, this application includes at least one of the following beneficial technical effects:

[0019] 1. This invention, through the cooperation of the linkage component and the abutment plate, automatically drives the scraper sleeve to move upward when the slide retracts, to scrape and clean the punching shear head and protect it, without the need for manual intervention, thereby improving the safety and automation of the equipment and achieving the advantages of automatic cleaning and protection.

[0020] 2. In this invention, the pressurizing component and the linkage component work together to pressurize and blow air while the scraper is cleaning, blowing the scraped debris away from the surface of the punching and shearing head, which further enhances the cleaning effect and ensures the punching and shearing accuracy.

[0021] 3. In this invention, the lubricating component automatically lubricates the punching head during the lifting and lowering process of the scraper sleeve, reducing the wear of the punching head and extending its service life.

[0022] 4. The present invention enables the centralized collection of cleaning debris by setting up a collection box, thereby avoiding debris scattering and polluting the equipment and the environment. Attached Figure Description

Detailed Implementation

[0033] The following is in conjunction with the appendix Figures 1-8 This application will be described in further detail.

[0034] This application discloses an integrated CNC equipment for automatic punching, shearing, and bending of busbar trunking. Please refer to... Figures 1-8 The system includes a frame 1, a base 2, a material conveyor 3, a material bundling seat 4, a bending structure 5, and a punching and shearing structure 6. Specifically, the bending structure 5 includes a lifting platform 51, a hydraulic telescopic rod 52, a center seat 53, a rotating seat 54, a drive assembly, two limiting clamps 57, and a bending component 58. The lifting platform 51 is slidably mounted on the side wall of the base 2. The side wall of the base 2 is provided with a vertical guide rail or guide groove. The lifting platform 51 slides back and forth in the vertical direction through a slider or guide wheel that is slidably engaged with the guide rail. The hydraulic telescopic rod 52 is fixed to the top side of the frame 1, and the output end of the hydraulic telescopic rod 52 is fixed to the bottom side of the lifting platform 51. The extension and retraction of the hydraulic telescopic rod 52 can drive the lifting platform 51 to rise and fall in the vertical direction to meet the bending processing needs of busbars of different thicknesses.

[0035] It should be noted that the center seat 53 is fixedly installed above the lifting platform 51, and the center seat 53 has a cylindrical structure; the rotating seat 54 is rotatably installed on the outer surface of the center seat 53, and the rotating seat 54 has a ring structure, with its inner ring and the outer ring of the center seat 53 rotatingly engaged through bearings. Two limiting clamps 57 are slidably installed on the top side of the center seat 53. The limiting clamps 57 can slide along the radial direction of the center seat 53 to clamp the busbar to be bent. The two limiting clamps 57 are arranged opposite each other, and can clamp and position the busbar from both sides respectively to prevent the busbar from shifting during the bending process. The clamping surfaces of the limiting clamps 57 are provided with anti-slip textures or rubber pads to enhance clamping stability and avoid damage to the surface of the busbar.

[0036] The driving component includes a drive motor 55 and a transmission gear 56. The drive motor 55 is mounted on the lifting platform 51, and its output shaft extends vertically upwards. The transmission gear 56 is located on the outside of the output shaft of the drive motor 55 and the rotating seat 54. Specifically, the transmission gear 56 includes a driving gear fixed to the output shaft of the drive motor 55 and a driven gear fixed to the outer ring of the rotating seat 54; the driving gear and the driven gear mesh with each other. When the drive motor 55 rotates, it drives the rotating seat 54 to rotate around the central seat 53 via the transmission gear 56. The bending component 58 includes a mold base 581 with a flange mounted on the top side of the rotating seat 54. The mold base 581 is fixedly connected to the top side of the rotating seat 54 via the flange and rotates together with the rotating seat 54.

[0037] The mold base 581 has several annularly spaced workpiece slots 582 inside. Molds 583 are detachably installed inside each of the workpiece slots 582. The molds 583 in different workpiece slots 582 can have different bending angles or different bending shapes to meet the bending requirements of different specifications of busbars. When the rotating base 54 rotates, the molds 583 in different workpiece slots 582 can be sequentially switched to the bending position.

[0038] A stop wheel 584 is provided on one side of the mold 583. The stop wheel 584 is rotatably mounted on the side of the mold 583 and rolls in contact with the busbar during the bending process to reduce frictional resistance and prevent indentations from forming on the surface of the busbar.

[0039] An adjusting bolt 585 is installed on one side of the abutment wheel 584, penetrating the interior of the mold base 581. The end of the adjusting bolt 585 abuts against the mounting base of the abutment wheel 584. Rotating the adjusting bolt 585 adjusts the extension of the abutment wheel 584 relative to the mold 583, thereby fine-tuning the bending angle and bending depth. The setting of the adjusting bolt 585 allows for precise adjustment of the bending parameters of the mold 583, improving bending accuracy and equipment adaptability.

[0040] The busbar is fed into the bending structure 5 via a conveying mechanism. The busbar is then transported to the top of the center seat 53, where two limiting clamps 57 clamp and position it from both sides. According to the preset bending angle, the drive motor 55 drives the rotating seat 54 to rotate via the transmission gear 56, rotating the workpiece slot 582, which contains the corresponding angle mold 583, to the bending position. The hydraulic telescopic rod 52 extends, pushing the lifting platform 51 upwards, causing the mold 583 to contact the busbar and bend it. During bending, the abutment wheel 584 rolls against the busbar, reducing friction and preventing indentations. The adjusting bolt 585 allows for fine-tuning of the position of the abutment wheel 584 during equipment debugging or after mold 583 replacement, ensuring bending accuracy. After bending, the hydraulic telescopic rod 52 retracts, the lifting platform 51 descends, the limiting clamps 57 release, and the bent busbar is discharged by the unloading mechanism. To perform bending at different angles, simply rotate the drive motor 55 to switch to the corresponding mold 583. There is no need to manually change the mold 583, which greatly improves production efficiency.

[0041] The frame 1 is fixedly installed above the base 2. The frame 1 is welded from high-strength square steel pipes, possessing sufficient strength and rigidity. The feeder 3 is located on one side of the frame 1 and is used to receive the busbar raw materials conveyed from upstream. The bundled material seat 4 is located at the output end of the feeder 3. The bundled material seat 4 is equipped with guide rollers and limiting baffles to guide and limit the busbars entering the processing area, ensuring that the busbars are conveyed along the predetermined path.

[0042] The bending structure 5 is located at the output end of the material bundle holder 4, and the punching and shearing structure 6 is located on one side of the material bundle holder 4. After the busbar is fed into the material bundle holder 4 via the conveyor frame 3, it is bent by the bending structure 5. After bending, it is sheared and processed by the punching and shearing structure 6. It should be noted that the processing sequence of the punching and shearing structure 6 and the bending structure 5 can be uniformly controlled by the CNC system to realize the integrated automatic processing of punching, shearing and bending.

[0043] In this embodiment, the punching and shearing structure 6 includes a slide block 61, a punching and shearing head 62, and a scraper sleeve 63. Specifically, the slide block 61 is slidably mounted on the frame 1 and is driven by a hydraulic cylinder or a servo motor, allowing it to slide back and forth in the horizontal direction. The punching and shearing head 62 is fixedly mounted on the end of the slide block 61, and can be replaced with a shearing die as needed.

[0044] To protect the punching head 62 after punching and shearing, a linkage component 64 connected to the scraper sleeve 63 is provided on the slide 61. An abutment plate 65, which abuts against the linkage component 64, is provided on one side of the slide 61. The abutment plate 65 is fixedly installed on the frame 1, and its surface is a smoothly transitioning guide surface. Specifically, the scraper sleeve 63 is slidably sleeved on the outside of the punching head 62, and a scraping groove 631 adapted to the punching head 62 is opened on the inner side of the scraper sleeve 63. The cross-sectional shape of the scraping groove 631 matches the cross-sectional shape of the punching head 62, and a small gap is maintained between the inner wall of the scraping groove 631 and the outer surface of the punching head 62. This gap is smaller than the size of the adhering impurities, so that the impurities can be scraped off during relative movement.

[0045] When the slide block 61 extends to perform the punching and shearing operation, the scraper sleeve 63 moves forward together with the slide block 61. At this time, the scraper sleeve 63 is in a retracted state relative to the punching and shearing head 62, with the front end of the punching and shearing head 62 protruding beyond the scraper sleeve 63 to perform the punching and shearing action. When the slide block 61 retracts and moves away, the scraper sleeve 63 moves upward through the abutment engagement between the linkage component 64 and the abutment plate 65. At this time, the scraper groove 631 scrapes material from the punching and shearing head 62, while the scraper sleeve 63 provides shielding and protection for the punching and shearing head 62.

[0046] The linkage component 64 includes a lifting plate 641, with a roller 642 rotatably mounted on one end of the lifting plate 641. The roller 642 rolls against the outer surface of the abutment plate 65. The roller 642 converts sliding friction into rolling friction, reducing wear and running resistance, and improving the service life and operational sensitivity of the linkage component 64.

[0047] A pull rod 644, fixed to the outer wall of the scraper sleeve 63, is installed on the outer wall of the lifting plate 641. One end of the pull rod 644 is fixedly connected to the lifting plate 641, and the other end is fixedly connected to the outer wall of the scraper sleeve 63, thereby transmitting the lifting motion of the lifting plate 641 to the scraper sleeve 63. The pull rod 644 is slidably connected to the slide 61; an inclined connecting rod 643 is hinged between the lifting plate 641 and the slide 61. The upper end of the connecting rod 643 is hinged to the lifting plate 641, and the lower end is hinged to the slide 61. When the slide 61 slides horizontally, the horizontal motion is converted into the lifting motion of the lifting plate 641 through the connecting rod 643.

[0048] When the slide block 61 retracts, the roller 642 first contacts the abutment plate 65 and rolls along its surface. As the slide block 61 continues to retract, it presses against the connecting rod 643, causing it to rotate and push the lifting plate 641 upward, which in turn drives the scraper sleeve 63 upward via the pull rod 644. During the upward movement of the scraper sleeve 63, the scraping groove 631 on its inner side slides relative to the punching head 62, scraping away copper and aluminum debris and impurities adhering to the outer surface of the punching head 62.

[0049] When the slide block 61 extends again, the roller 642 rolls in the opposite direction along the abutment plate 65, the lifting plate 641 moves down under the action of gravity or the return spring, the scraper sleeve 63 returns to its original position, and the front end of the punching and shearing head 62 re-exposes, ready for the next punching and shearing operation.

[0050] The punching and shearing structure 6 also includes a pressurizing assembly 66 and a valve pipe 68. The valve pipe 68 is installed between the pressurizing assembly 66 and the scraper sleeve 63.

[0051] The pressurization assembly 66 includes a hollow pressurization cylinder 661, a pressurization piston 662 slidably sealed inside the pressurization cylinder 661, and a return spring 663 wound around and installed outside the pressurization piston 662. One end of the pressurization cylinder 661 has an air inlet or is connected to an external air source. When the pressurization piston 662 reciprocates inside the pressurization cylinder 661, it can compress and pressurize the gas inside the cylinder. One end of a valve pipe 68 is fixed to and connected to the pressurization cylinder 661.

[0052] One end of the booster piston 662 extends to the outside of the booster cylinder 661, and an abutment block 664 is installed at the end of the piston extending outside the booster cylinder 661 to abut against the eccentric wheel 646. The booster cylinder 661 is fixed to the outer wall of the lifting plate 641 and rises and falls together with the lifting plate 641.

[0053] The linkage assembly 64 also includes a rotating shaft 645 connected to one end of the roller 642, and an eccentric wheel 646 fixed to the other end of the rotating shaft 645. When the roller 642 rotates, the eccentric wheel 646 rotates synchronously through the rotating shaft 645.

[0054] When the slide block 61 retracts, the roller 642 first contacts the abutment plate 65. As the slide block 61 continues to retract, it presses against the connecting rod 643, causing it to rotate and push the lifting plate 641 upward, thereby driving the scraper sleeve 63 to move. Simultaneously, the roller 642 rotates along the abutment plate 65, driving the eccentric wheel 646 to rotate via the rotating shaft 645. During rotation, the eccentric wheel 646 periodically abuts against the abutment block 664, pushing the pressure boosting piston 662 to reciprocate within the pressure boosting cylinder 661, compressing and pressurizing the gas within the cylinder.

[0055] The pressurized gas is delivered to the inside of the scraper sleeve 63 via valve pipe 68. A nozzle 681 is installed at one end of valve pipe 68 and is fixed inside the scraper sleeve 63. Compressed gas is ejected through nozzle 681 to blow away debris scraped from the scraper head 62 by the surface of the scraper head 62, further enhancing the cleaning effect. There are two valve pipes 68 connected together, one of which is connected to the pressurizing cylinder 661. It should be noted that both valve pipe 68 and pressurizing cylinder 661 are equipped with check valves. When the scraper sleeve 63 cleans the scraper head 62, the pressurizing assembly 66 provides pressurized air, effectively enhancing the cleaning effect. The return spring 663 pushes the pressurizing piston 662 to reset when the eccentric wheel 646 disengages, preparing for the next pressurization.

[0056] To facilitate waste collection, a collection box 67 is snap-fitted to the bottom of the scraper sleeve 63. The collection box 67 has a box-shaped structure with an opening at the top, directly opposite the lower area of ​​the scraper sleeve 63. Debris scraped by the scraper trough 631 and impurities blown off by the nozzle 681 fall into the collection box 67 under gravity, thus centrally collecting the impurities generated during the scraper sleeve 63's cleaning process and preventing debris from scattering and contaminating the equipment and working environment. The collection box 67 is detachably connected to the scraper sleeve 63 via a snap-fit ​​or sliding groove, facilitating periodic removal and cleaning.

[0057] To further protect the shear head 62, the scraper sleeve 63 is internally equipped with a lubricating element 69 for lifting and lowering. The lubricating element 69 includes a mating plate 691, a first guide plate 692, and a second guide plate 693. The first guide plate 692 is fixed to the top side of the mating plate 691, and the second guide plate 693 is fixed to the bottom side of the slide block 61, with an interference fit between them. The contact surfaces of the first guide plate 692 and the second guide plate 693 are mutually mating inclined or arc-shaped surfaces. When the two interference-fitted surfaces move relative to each other, a component force perpendicular to the contact surface is generated.

[0058] The lubricating component 69 also includes a guide rod 694 fixed to one side of the bonding plate 691. The guide rod 694 passes through the interior of the scraper sleeve 63, and there is a sliding fit between the guide rod 694 and the scraper sleeve 63. A second return spring 695 is wound around the outer surface of the guide rod 694. One end of the second return spring 695 abuts against the bonding plate 691, and the other end abuts against the inner wall of the scraper sleeve 63, always providing the bonding plate 691 with a spring force away from the scraper sleeve 63.

[0059] When the scraper sleeve 63 moves upward, the interference fit between guide plate 1 692 and guide plate 2 693 causes guide plate 2 693 to exert an oblique thrust on guide plate 1 692, pushing the bonding plate 691 to move along the guide direction of guide rod 694, so that the bonding plate 691 is tightly bonded to the punch head 62. The side of the bonding plate 691 facing the punch head 62 is provided with a lubricating material layer, such as oil-impregnated graphite or a solid lubricating coating, to lubricate the outer surface of the punch head 62 during bonding; when the scraper sleeve 63 moves downward to reset, guide plate 1 692 and guide plate 2 693 disengage from the interference fit, and the bonding plate 691 resets under the action of reset spring 2 695, separating from the punch head 62. It should be noted that the lubricating component 69 enables the punching head 62 to be automatically lubricated after each cleaning action of the scraper sleeve 63, reducing friction and wear between the punching head 62 and the scraper sleeve 63, extending the service life of the punching head 62, and ensuring the smoothness of the lifting and lowering action of the scraper sleeve 63.

[0060] Combined with appendix Figures 1-8 The working principle of the above embodiments is as follows:

[0061] When the equipment is working, the busbars of the busbar trunking are automatically fed through the feeding frame 3, and the busbars to be processed are smoothly transported to the position of the binding seat 4. The binding seat 4 limits and tightens the busbars and accurately positions them to prevent the busbars from shifting or shaking during processing, thus ensuring the accuracy of the processing reference. The busbars are then transported to the bending structure 5 at the output end. The bending structure 5 completes the bending and forming of the busbars at multiple angles and in multiple specifications through multi-dimensional limiting, rotation, and bending adjustment mechanisms. After bending is completed, the lateral punching and shearing structure 6 is activated to perform CNC precision punching and shearing on the fixed busbars, completing the busbar length cutting, edge trimming and other processes. The processes are connected without interruption, realizing integrated automated processing.

[0062] During the punching and shearing operation, the slide block 61 extends forward, driving the punching and shearing head 62 to move forward to complete the punching and shearing of the busbar. After the processing is completed, the slide block 61 retracts and resets.

[0063] During the retraction displacement of the slide block 61, the linkage component 64 and the fixedly arranged abutment plate 65 form an abutment linkage cooperation. The roller 642 at the end of the lifting plate 641 of the linkage component 64 first rolls into contact with the surface of the abutment plate 65. As the slide block 61 continues to retract, the inclined hinged connecting rod 643 is squeezed and rotates, thereby vertically pushing the lifting plate 641 to move upward. The lifting plate 641 drives the outer fixed scraper sleeve 63 to move upward synchronously through the pull rod 644, so that the scraping groove 631 on the inner side of the scraper sleeve 63 slides against the outer wall of the punching and shearing head 62, automatically scraping off the iron filings, waste, burrs and impurities adhering to the surface of the punching and shearing head 62. At the same time, the scraper sleeve 63 after moving upward can completely cover the working end of the punching and shearing head 62, realizing protection in the idle state and avoiding the accumulation of dust and debris.

[0064] Meanwhile, as the roller 642 rolls, it drives the eccentric wheel 646 to rotate synchronously via the rotating shaft 645. The eccentric wheel 646 continuously abuts against the abutment block 664 of the pressurizing component 66, pushing the pressurizing piston 662 to slide and compress inside the pressurizing cylinder 661, compressing the internal gas to form a high-pressure airflow. The high-pressure airflow is delivered to the nozzle 681 inside the scraper sleeve 63 through two interconnected sets of valve pipes 68, performing high-pressure air blowing to clean the surface of the punching shear head 62. Combined with the mechanical scraping method of the scraper groove 631, it achieves a dual cleaning effect of mechanical cleaning and pneumatic cleaning, thoroughly removing fine impurities.

[0065] While the scraper sleeve 63 moves upward for cleaning, the internal lubrication components 69 work synchronously. Guide plate 1 692 and guide plate 2 693 are pressurized by an interference fit, pushing the contact plate 691 to contact the outer wall of the punching head 62. Combined with the elastic fit of guide rod 694 and return spring 2 695, uniform lubrication of the outer wall of the punching head 62 is achieved, reducing wear from the reciprocating motion of the punching head 62. The scraped-off impurities and iron filings can fall directly into the collection box 67, which is snapped into the bottom of the scraper sleeve 63, achieving centralized collection of impurities and preventing secondary contamination of the equipment. After a single cleaning and lubrication cycle, each structure automatically resets under the action of return spring 1 663 and return spring 2 695, awaiting the next punching and shearing operation.

[0066] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
