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.

[0023] Example 1:

[0024] This utility model provides a sealing ring punching device, including a worktable 1. A translation mechanism 2 and a first punching mechanism 3 are fixedly installed on the worktable 1. A template 4 is fixedly installed at the drive end of the translation mechanism 2, and the template 4 has a die hole 5. A first punching plate 6 is fixedly installed at the drive end of the first punching mechanism 3. A support column 7 is fixedly connected to the first punching plate 6, and the support column 7 has a through hole 8. A support platform 10 is fixedly installed on the worktable 1 via a column 9. A second punching mechanism 11 is fixedly installed on the support platform 10. A second punching plate 12 and a third punching plate 13 are fixedly installed at the drive end of the second punching mechanism 11. A first punching column 14 is fixedly connected to the second punching plate 12, and a second punching column 15 is fixedly connected to the third punching plate 13. The support column 7 has an annular groove 16. A clamping plate 17 is movably installed on both the second punching plate 12 and the third punching plate 13 via a guide column 22. A spring 18 is fixedly installed between the second punching plate 12, the third punching plate 13, and the clamping plate 17. The first stamping plate 6 is fixedly installed with the first collecting hopper 19. The worktable 1 is provided with a discharge port 20, and the discharge port 20 is fixedly installed with the second collecting hopper 21.

[0025] Through the above technical solution, in this utility model, the second stamping plate 12 and the first stamping plate 6 are installed vertically aligned, and the two work together to complete the punching process. During assembly, it is necessary to ensure that the through hole 8 of the support column 7 of the first stamping plate 6 is precisely aligned with the axis of the first punching column 14 of the second stamping plate 12. During operation, the sealing ring plate is first placed on the template 4, aligning the sealing ring with the die hole 5 of the template 4. Then, the translation mechanism 2 is activated, moving the template 4 and the sealing ring plate below the second stamping plate 12, at which point the axes of the die hole 5, the through hole 8, and the first punching column 14 are aligned. Next, the first stamping mechanism 3 drives the first stamping plate 6 upward, and the support column 7 supports the sealing ring at the die hole 5; the second stamping mechanism 11 then drives the second stamping plate 12 downward, and the first punching column 14 inserts into the through hole 8 of the support column 7, its sidewall shearing against the inner wall of the through hole 8, cutting off the edge material in the central area of ​​the sealing ring. Subsequently, the first stamping mechanism 3 and the second stamping mechanism 11 are reset, and the translation mechanism 2 is restarted, moving the template 4 and the sealing ring plate to below the third stamping plate 13, aligning the axis of the die hole 5 with the axis of the second punching post 15. The second stamping mechanism 11 drives the third stamping plate 13 to move downward, and the second punching post 15 is inserted into the die hole 5. Its sidewall forms a shearing action with the inner wall of the die hole 5, cutting and separating the sealing ring from the sealing ring plate, thereby quickly completing the cutting operation of the sealing ring and significantly improving work efficiency.

[0026] Example 2:

[0027] In this embodiment, a translation mechanism 2 and a first stamping mechanism 3 are fixedly installed on the workbench 1. The drive end of the translation mechanism 2 is firmly connected to a template 4, which has multiple die holes 5 for placing the sealing ring plate. The drive end of the first stamping mechanism 3 is fixedly installed with a first stamping plate 6, which cooperates with the template 4 through a support column 7. The support column 7 has through holes 8 inside to facilitate subsequent punching operations. The workbench 1 is supported by a support platform 10 by a column 9. A second stamping mechanism 11 is installed on the support platform 10. The drive end of the second stamping mechanism 11 simultaneously fixes a second stamping plate 12 and a third stamping plate 13. The second stamping plate 12 is connected to a first punching column 14 for cutting off the edge material in the center area of ​​the sealing ring; the third stamping plate 13 is connected to a second punching column 15 for cutting and separating the sealing ring from the plate. The entire device has a compact structure, and all components work together to ensure a precise and efficient punching process.

[0028] During operation, the sealing ring plate is first placed on the template 4, aligning it with the die hole 5. The translation mechanism 2 is activated, moving the template 4 and the plate below the second stamping plate 12. At this point, the axes of the die hole 5, the through hole 8 of the support column 7, and the first punching column 14 are precisely aligned. The first stamping mechanism 3 drives the first stamping plate 6 upwards, and the support column 7 lifts the sealing ring at the die hole 5, providing support. Subsequently, the second stamping mechanism 11 drives the second stamping plate 12 downwards, and the first punching column 14 inserts into the through hole 8 of the support column 7. Its sidewall and the inner wall of the through hole 8 generate shearing force, effectively removing the edge material in the central area of ​​the sealing ring, completing the initial punching.

[0029] After the initial punching is completed, the first punching mechanism 3 and the second punching mechanism 11 are reset, and the translation mechanism 2 is restarted, moving the template 4 and the sealing ring plate below the third punching plate 13, aligning the axis of the die hole 5 with the axis of the second punching post 15. The second punching mechanism 11 drives the third punching plate 13 to move downward, and the second punching post 15 inserts into the die hole 5. Its sidewall forms a shearing action with the inner wall of the die hole 5, cutting and separating the sealing ring from the sealing ring plate. The entire process is highly automated, requiring no manual intervention, and significantly improving cutting accuracy and efficiency.

[0030] This embodiment achieves fully automated sealing ring punching through the coordinated operation of the translation mechanism 2 and multiple stamping mechanisms. The drive ends of the first stamping mechanism 3 and the second stamping mechanism 11 respectively control different stamping plates, ensuring the accuracy and stability of the punching action. The design of the cooperation between the support column 7 and the punching column effectively utilizes the shearing principle, avoiding the shortcomings of traditional manual cutting. The overall structure of the device is reasonable, the operation is simple, it is suitable for mass production environments, and it can significantly reduce labor intensity and improve product quality consistency.

[0031] Example 3:

[0032] In this embodiment, the support column 7 is provided with an annular groove 16, the size of which is similar to that of the sealing ring, and is used to fix the sealing ring during the punching process. When the support column 7 supports the sealing ring located at the die hole 5, the lower half of the sealing ring will be embedded in the annular groove 16, thereby achieving a firm fixation and effectively preventing the sealing ring from shifting or deforming during the punching process, thereby improving the cutting accuracy and overall processing quality of the sealing ring.

[0033] In the specific operation, the sealing ring plate is first placed on the template 4, ensuring that the sealing ring is precisely aligned with the die hole 5 of the template 4. Then, the translation mechanism 2 is activated, moving the template 4 along with the sealing ring plate below the second stamping plate 12. At this point, the axis of the die hole 5, the axis of the through hole 8 of the support column 7, and the axis of the first punching column 14 are completely aligned. Next, the first stamping mechanism 3 drives the first stamping plate 6 to move upward, and the support column 7 rises accordingly, supporting the sealing ring at the die hole 5. During this process, the lower half of the sealing ring is embedded in the annular groove 16 of the support column 7. The size of the annular groove 16 matches the sealing ring, tightly wrapping it and providing stable support and positioning. This ensures that the sealing ring maintains a fixed posture during subsequent punching operations, preventing displacement or twisting due to external forces, thereby significantly improving cutting accuracy.

[0034] Subsequently, the second stamping mechanism 11 drives the second stamping plate 12 to move downwards, and the first cutting post 14 is inserted into the through hole 8 of the support post 7. A shearing action is generated between the side wall of the first cutting post 14 and the inner wall of the through hole 8, precisely cutting off the edge material in the center area of ​​the sealing ring. Because the sealing ring is effectively fixed by the annular groove 16, the shearing process is more stable and precise, reducing cutting errors caused by the shaking of the sealing ring. After the center edge material is removed, the first stamping mechanism 3 and the second stamping mechanism 11 are reset, and the translation mechanism 2 is restarted, moving the template 4 and the sealing ring plate below the third stamping plate 13, aligning the axis of the die hole 5 with the axis of the second cutting post 15.

[0035] Finally, the second stamping mechanism 11 drives the third stamping plate 13 to move downwards, and the second punching post 15 inserts into the die hole 5. Its sidewall forms a shearing action with the inner wall of the die hole 5, cutting and separating the sealing ring from the sealing ring plate. Throughout the process, the design of the annular groove 16 ensures that the sealing ring remains stable when supported by the support post 7, avoiding the offset problem commonly found in traditional manual cutting. This achieves efficient and high-precision sealing ring punching operation, significantly improving production efficiency and product quality.

[0036] Example 4:

[0037] In this embodiment, both the second stamping plate 12 and the third stamping plate 13 are movably mounted with a clamping plate 17 via guide posts 22. A spring 18 is fixedly installed between the clamping plate 17 and the second stamping plate 12 or the third stamping plate 13. During the punching process, when the second stamping plate 12 or the third stamping plate 13 moves downward, the clamping plate 17 first contacts the surface of the sealing ring plate. The preload of the spring 18 stably presses the plate onto the template 4, preventing the plate from shifting or deforming during punching. The clamping plate 17 is provided with insertion holes corresponding to the first punching post 14 and the second punching post 15. The size of the insertion holes is slightly larger than the diameter of the punching post to ensure that the punching post can pass through smoothly. After the clamping plate 17 clamps the plate 17, the second stamping plate 12 or the third stamping plate 13 continues to move downward. The spring 18 is compressed, and the first punching post 14 or the second punching post 15 passes through the insertion holes and cooperates with the die hole 5 on the template 4 or the through hole 8 of the support post 7 to complete the shearing operation. The guide post 22 guides the clamping plate 17 to move smoothly in the vertical direction, preventing the clamping plate 17 from tilting or shaking during clamping and releasing. The spring 18 provides continuous pressure to ensure that the clamping plate 17 always remains in contact with the plate until the punching is completed. This structure, through the clamping and punching sequence of the clamping plate 17, effectively improves the punching accuracy and ensures the neatness and dimensional consistency of the sealing ring edge.

[0038] In specific operation, when the second stamping plate 12 moves down to cut off the center edge material, the clamping plate 17 first presses down on the sealing ring plate, fixing the plate to the surface of the template 4 and preventing the plate from sliding during the punching process. Subsequently, the second stamping plate 12 continues to move down, the spring 18 is compressed, and the first punching post 14 passes through the insertion hole of the clamping plate 17 and inserts into the through hole 8 of the support post 7, cutting off the center edge material through the side wall shearing action. Similarly, when the third stamping plate 13 moves down to cut the sealing ring, the clamping plate 17 first clamps the plate 17, and then the third stamping plate 13 moves down, the spring 18 is compressed, and the second punching post 15 passes through the insertion hole and enters the die hole 5 of the template 4, completing the separation of the sealing ring from the plate. The guide post 22 ensures the straightness and stability of the movement of the clamping plate 17, while the spring 18 automatically adjusts the clamping force according to the thickness of the plate to adapt to different working conditions. This design not only improves the stability of the punching process, but also reduces errors caused by plate movement, thereby significantly improving the processing quality and production efficiency of the sealing ring.

[0039] During operation, the clamping plate 17, through the coordinated action of the guide post 22 and the spring 18, dynamically clamps and releases the sealing ring plate. In the initial downward movement of the second stamping plate 12 or the third stamping plate 13, the clamping plate 17 quickly clamps the sealing ring plate, forming a stable support base. As the stamping plate continues to move downward, the spring 18 provides buffering and adaptive pressure, ensuring that the clamping plate 17 maintains effective contact throughout the punching process. The design of the insertion hole allows the punching post to pass through unobstructed, avoiding interference between the punching post and the clamping plate 17. Simultaneously, the guiding function of the guide post 22 prevents lateral displacement of the clamping plate 17, further enhancing punching accuracy. This structure is particularly suitable for punching rubber sealing rings, effectively handling the elastic deformation of rubber materials and ensuring that the punched sealing ring has precise dimensions and smooth edges, meeting high-precision sealing requirements.

[0040] Example 5:

[0041] In this embodiment, the first stamping plate 6 is fixedly mounted with a first collecting hopper 19, which is used to collect the edge material from the center area of ​​the cut sealing ring. The first collecting hopper 19 is provided with a first material inlet, which can be connected to a negative pressure system. The edge material is quickly sucked away by the negative pressure adsorption, ensuring that the edge material is cleaned up in time during the punching process and avoiding accumulation that affects subsequent operations.

[0042] During device operation, the sealing ring plate is first placed on the template 4 and moved below the second stamping plate 12 by the translation mechanism 2. At this time, the first stamping mechanism 3 drives the first stamping plate 6 to move upward, and the support column 7 supports the sealing ring at the die hole 5. Simultaneously, the second stamping mechanism 11 drives the second stamping plate 12 to move downward, and the first cutting column 14 inserts into the through hole 8 of the support column 7. Its side wall and the inner wall of the through hole 8 generate a shearing action, cutting off the edge material in the central area of ​​the sealing ring. The cut edge material falls into the first collection hopper 19 and is quickly sucked away by the negative pressure system connected to the first material interface, realizing the automatic collection and cleaning of edge material, improving operating efficiency and cleanliness.

[0043] Subsequently, the first stamping mechanism 3 and the second stamping mechanism 11 reset, and the translation mechanism 2 restarts, moving the template 4 and the sealing ring plate below the third stamping plate 13. The second stamping mechanism 11 drives the third stamping plate 13 downward, and the second cutting column 15 inserts into the die hole 5. Its sidewall forms a shearing action with the inner wall of the die hole 5, cutting and separating the sealing ring from the sealing ring plate. Throughout the process, the first collecting hopper 19 continues to work to ensure timely processing of edge material and avoid residue affecting cutting accuracy and equipment operation.

[0044] The design of the first hopper 19 not only optimizes the edge material collection process but also enhances the cleaning effect through negative pressure adsorption, reducing manual intervention and improving the automation level and production efficiency of the device. This embodiment, by integrating the first hopper 19, effectively solves the problem of inconvenient edge material handling in traditional manual cutting, achieving efficient and precise operation of the sealing ring punching.

[0045] Example 6:

[0046] In this embodiment, the workbench 1 is equipped with a discharge port 20, on which a second collection hopper 21 is fixedly installed. The second collection hopper 21 is designed as a funnel, with its upper opening tightly connected to the discharge port 20 and its lower portion having an interface for connecting to a negative pressure system. During the punching process, after the sealing ring is cut and separated from the sealing ring plate, each individual sealing ring falls naturally under gravity and enters the second collection hopper 21 through the discharge port 20. The negative pressure interface of the second collection hopper 21 is connected to an external suction device, generating a continuous negative pressure airflow. This airflow creates suction inside the second collection hopper 21, rapidly drawing in the falling sealing rings and transporting them to a designated collection location. This design effectively avoids the accumulation or blockage of sealing rings during the discharge process, ensuring that the punched sealing rings can be transferred quickly and orderly, thereby improving overall production efficiency.

[0047] During the operation of the punching device, the negative pressure suction function of the second collecting hopper 21 works in conjunction with the punching action. When the second punching mechanism 11 drives the third punching plate 13 to move downward, the second punching column 15 inserts into the die hole 5 of the template 4. Its side wall forms a shearing action with the inner wall of the die hole 5, cutting and separating the sealing ring from the sealing ring plate. At this time, the separated sealing ring loses its support and immediately falls out of the die hole 5. Since the second collecting hopper 21 is located below the discharge port 20 and the internal negative pressure environment has been pre-established, once the sealing ring enters the second collecting hopper 21, it is captured by the negative pressure airflow and quickly sucked away. This continuous suction mechanism not only shortens the residence time of the sealing ring in the device, but also reduces the need for manual intervention, making the punching process more automated.

[0048] The structural design of the second collecting hopper 21 takes into account the size and shape characteristics of the sealing ring. Its internal channels have smooth transitions, avoiding sharp corners or narrow sections to prevent the sealing ring from getting stuck during transportation. Simultaneously, the intensity of the negative pressure suction is rationally configured to ensure that the sealing ring is reliably sucked away without causing deformation or damage due to excessive suction. Furthermore, the installation position of the second collecting hopper 21 is precisely calculated to ensure a seamless connection with the discharge port 20, guaranteeing an unobstructed path for the sealing ring to fall. Through this design, the punching device achieves efficient cutting while simultaneously realizing the automatic collection and transfer of the sealing ring, greatly improving operational continuity and ease of operation.

[0049] In practical applications, the negative pressure system of the second collecting hopper 21 can be flexibly adjusted to adapt to the punching requirements of sealing rings of different specifications. For example, for smaller or lighter sealing rings, the negative pressure suction can be appropriately increased to ensure effective removal; while for larger or heavier sealing rings, the suction parameters can be adjusted to avoid over-adsorption. This adaptive design enables the punching device to handle various types of sealing ring products, enhancing the equipment's versatility and practicality. Overall, the combination of the second collecting hopper 21 and the discharge port 20 not only optimizes the material handling process after punching but also significantly reduces manual labor intensity, providing a reliable guarantee for the large-scale production of sealing rings.
