Description

Technical Field

[0001] This utility model belongs to the technical field of rubber processing equipment, and specifically relates to a sealing ring punching machine. Background Technology

[0002] Rubber sealing rings, as key sealing components, are widely used in various types of mechanical equipment and can withstand the corrosion of various petroleum-based oils and chemical media. Their processing typically involves: extruding rubber raw materials and placing them on a lower die, then pressing down with an upper die to close the lower die, forming multiple sealing rings as a single piece. After mold opening, the formed rubber part remains integrated with the surrounding waste material, forming a single sealing ring plate. The sealing ring needs to be separated from the edge material, a process currently largely done manually, which is not only labor-intensive but also difficult to guarantee in terms of cutting accuracy and efficiency.

[0028] Through the above technical solution, the second stamping plate 23 and the first stamping plate 14 of this utility model are installed vertically aligned, and the two work together to complete the punching operation. During assembly, the through hole 16 of the support column 15 of the first stamping plate 14 is aligned with the axis of the first punching column 25 of the second stamping plate 23. During operation, the sealing ring plate is placed on the template 9, so that the sealing ring on the sealing ring plate is aligned with the die hole 10 of the template 9. The translation mechanism 3 is activated, and the translation motor 5 drives the belt 7 to move the moving table 6 along the slide rail 8, transferring the template 9 and the sealing ring plate on it to the bottom of the second stamping plate 23, so that the axis of the die hole 10 of the template 9 is aligned with the axis of the through hole 16 and the axis of the first punching column 25.

The second stamping mechanism 19 is activated again, driving the third stamping plate 24 downwards, causing the second punching post 26 to insert into the die hole 10 of the template 9. The side wall of the second punching post 26 forms a shearing action with the inner wall of the die hole 10, cutting and separating the sealing ring from the sealing ring plate, quickly completing the cutting operation of the sealing ring and improving work efficiency.

[0029] Example 2:

[0030] In this embodiment, a worktable 2 is fixedly mounted on the frame 1. A translation mechanism 3 and a first stamping mechanism 4 are fixedly mounted on the worktable 2. The translation mechanism 3 includes a translation motor 5 and a moving platform 6. The drive end of the translation motor 5 is driven by the moving platform 6 via a belt 7. The worktable 2 is slidably connected to the moving platform 6 via a slide rail 8, allowing the moving platform 6 to move smoothly along the slide rail 8. A template 9 is fixedly mounted on the moving platform 6. The template 9 has mold holes 10 for placing sealing ring plates.

[0031] The first stamping mechanism 4 includes a first motor 11 and a first lifting platform 12. The drive end of the first motor 11 is connected to the first lifting platform 12 via a telescopic mechanism 13. The telescopic mechanism 13 consists of a screw and a nut. The linear movement of the nut is achieved by rotating the screw. The nut is fixedly connected to the first lifting platform 12, thereby driving the first lifting platform 12 to rise and fall. A first stamping plate 14 is fixedly installed on the first lifting platform 12. A support column 15 is fixedly connected to the first stamping plate 14. The support column 15 has a through hole 16 for supporting the sealing ring during the stamping process.

[0032] The workbench 2 is fixedly mounted with a support platform 18 via a column 17, and a second stamping mechanism 19 is fixedly mounted on the support platform 18. The second stamping mechanism 19 includes a second motor 20 and a second lifting platform 21. The drive end of the second motor 20 is driven by the second lifting platform 21 via a lead screw 22. A second stamping plate 23 and a third stamping plate 24 are fixedly mounted on the second lifting platform 21. A first punching column 25 is fixedly connected to the second stamping plate 23, and a second punching column 26 is fixedly connected to the third stamping plate 24, which are used for punching operations at different stages.

[0033] During the punching process, the sealing ring plate is first placed on the template 9, aligning the sealing ring on the plate with the die hole 10 of the template 9. The translation mechanism 3 is activated, and the translation motor 5 drives the moving table 6 along the slide rail 8 via the belt 7, transferring the template 9 and its sealing ring plate below the second stamping plate 23, aligning the axis of the die hole 10 of the template 9 with the through hole 16 of the support column 15 and the axis of the first punching column 25. The first stamping mechanism 4 is activated, and the first motor 11 drives the first lifting platform 12 upward via the telescopic mechanism 13, causing the first stamping plate 14 and its support column 15 to support the sealing ring located at the die hole 10. The second stamping mechanism 19 is then activated, and the second motor 20 drives the second lifting platform 21 downward via the lead screw 22, causing the second stamping plate 23 and its first punching column 25 to insert into the through hole 16 of the support column 15. The side wall of the first punching column 25 forms a shearing action with the inner wall of the through hole 16, cutting off the edge material in the central area of ​​the sealing ring.

[0034] After the center edge material is removed, the first stamping mechanism 4 and the second stamping mechanism 19 are reset. The translation mechanism 3 is activated again, moving the template 9 and its sealing ring plate below the third stamping plate 24, aligning the axis of the die hole 10 of the template 9 with the axis of the second punching post 26. The second stamping mechanism 19 is activated again, driving the third stamping plate 24 downward, causing the second punching post 26 to insert into the die hole 10 of the template 9. The side wall of the second punching post 26 forms a shearing action with the inner wall of the die hole 10, cutting and separating the sealing ring from the sealing ring plate. The entire process, through two punching operations, quickly completes the cutting of the sealing ring, improving work efficiency and cutting accuracy.

[0035] Example 3:

[0036] In this embodiment, the workbench 2 is fixedly mounted on the frame 1. The translation mechanism 3 includes a translation motor 5 and a moving platform 6. The drive end of the translation motor 5 is connected to the moving platform 6 via a belt 7. The workbench 2 is slidably connected to the moving platform 6 via a slide rail 8. A template 9 is fixedly mounted on the moving platform 6, and the template 9 has a die hole 10. The first stamping mechanism 4 includes a first motor 11 and a first lifting platform 12. The drive end of the first motor 11 is connected to the first lifting platform 12 via a telescopic mechanism 13. The telescopic mechanism 13 consists of a screw and a nut. The linear movement of the nut is achieved by rotating the screw. The nut is fixed to the first lifting platform 12, thereby driving the first lifting platform 12 to rise and fall. A first stamping plate 14 is fixedly mounted on the first lifting platform 12. A support column 15 is fixedly connected to the first stamping plate 14, and the support column 15 has a through hole 16. The workbench 2 is fixedly mounted with a support platform 18 via a column 17. A second stamping mechanism 19 is fixedly mounted on the support platform 18. The second stamping mechanism 19 includes a second motor 20 and a second lifting platform 21. The drive end of the second motor 20 is connected to the second lifting platform 21 via a lead screw 22. A second stamping plate 23 and a third stamping plate 24 are fixedly mounted on the second lifting platform 21. A first punching column 25 is fixedly connected to the second stamping plate 23, and a second punching column 26 is fixedly connected to the third stamping plate 24.

[0037] In this embodiment, the support post 15 is provided with an annular groove 27, the size of which is approximately the same as that of the sealing ring, for fixing the sealing ring. When the support post 15 supports the sealing ring located at the die hole 10, the lower half of the sealing ring is embedded in the annular groove 27, achieving the purpose of fixing, thereby improving the cutting accuracy of the sealing ring. The design of the annular groove 27 ensures that the sealing ring remains stable during the punching process, avoiding cutting errors caused by displacement or deformation, and ensuring that the sealing ring has neat edges and accurate dimensions.

[0038] The working principle of this embodiment is as follows: First, the sealing ring plate is placed on the template 9, aligning the sealing ring on the sealing ring plate with the die hole 10 of the template 9. The translation mechanism 3 is activated, and the translation motor 5 drives the belt 7, moving the moving table 6 along the slide rail 8, transferring the template 9 and the sealing ring plate on it below the second stamping plate 23, aligning the axis of the die hole 10 of the template 9 with the through hole 16 of the support column 15 and the axis of the first punching column 25. The first stamping mechanism 4 is activated, and the first motor 11 drives the first lifting platform 12 upward through the telescopic mechanism 13, moving the first stamping plate 14 and the support column 15 upward, so that the support column 15 supports the sealing ring located at the die hole 10. At this time, the lower half of the sealing ring is embedded in the annular groove 27 of the support column 15, achieving fixation. The second stamping mechanism 19 is activated, and the second motor 20 drives the second lifting platform 21 to move downwards via the lead screw 22, causing the second stamping plate 23 and the first punching column 25 to move downwards. The first punching column 25 is inserted into the through hole 16 of the supporting column 15. The side wall of the first punching column 25 forms a shearing action with the inner wall of the through hole 16, cutting off the edge material in the center area of ​​the sealing ring. After the first stamping mechanism 4 and the second stamping mechanism 19 are reset, the translation mechanism 3 is activated again, transferring the template 9 and the sealing ring plate on it to below the third stamping plate 24, aligning the axis of the die hole 10 of the template 9 with the axis of the second punching column 26. The second stamping mechanism 19 is activated again, driving the third stamping plate 24 to move downwards, causing the second punching column 26 to insert into the die hole 10 of the template 9. The side wall of the second punching column 26 forms a shearing action with the inner wall of the die hole 10, cutting and separating the sealing ring from the sealing ring plate, quickly completing the sealing ring cutting operation and improving work efficiency.

[0039] The design of the annular groove 27 ensures that the sealing ring is firmly fixed during the punching process, preventing displacement or deformation caused by punching force, ensuring the flatness and dimensional accuracy of the cut edges, and improving production efficiency and product quality. The entire punching process is highly automated, reducing manual intervention and making it suitable for industrial applications involving mass production of sealing rings.

[0040] Example 4:

[0041] In this embodiment, both the second stamping plate 23 and the third stamping plate 24 are movably mounted with a clamping plate 29 via guide posts 28. A spring 30 is fixedly installed between the clamping plate 29 and the second stamping plate 23 or the third stamping plate 24. During the punching process, when the second stamping plate 23 or the third stamping plate 24 moves downward, the clamping plate 29 first contacts the sealing ring plate, and a uniform clamping force is applied through the compression action of the spring 30 to ensure that the sealing ring plate is stably fixed before punching. The clamping plate 29 is provided with insertion holes corresponding to the first punching post 25 and the second punching post 26. The positions of these insertion holes are precisely aligned with the axis of the punching post, allowing the punching post to pass smoothly.

[0042] When the second stamping plate 23 moves downward to perform the punching operation, the clamping plate 29 first presses against the sealing ring plate. The spring 30 is compressed, generating a reaction force that keeps the clamping plate 29 tightly against the surface of the plate, preventing the plate from shifting or deforming during the punching process. Subsequently, the second stamping plate 23 continues to move downward, and the first punching post 25 passes through the insertion hole of the clamping plate 29 and engages with the die hole 10 of the template 9 to complete the shearing of the edge material in the central area. The guide post 28 guides the vertical movement of the clamping plate 29, ensuring that the clamping plate 29 remains parallel under the action of the spring 30, avoiding precision loss caused by tilting.

[0043] Similarly, during the final cutting as the third stamping plate 24 moves down, the clamping plate 29 first clamps the sealing ring plate, with the spring 30 providing cushioning and clamping force. The second cutting post 26 then passes through the insertion hole and forms a shearing action with the inner wall of the die hole 10 in the template 9, separating the sealing ring from the plate. Throughout the process, the clamping action of the clamping plate 29 precedes the punching operation. Through the synergistic action of the guide post 28 and the spring 30, the vibration and displacement of the plate are effectively suppressed, thereby improving the punching accuracy and finished product quality.

[0044] This design principle is based on a staged punching mechanism. The clamping plate 29 stabilizes the sheet before punching, the spring 30 absorbs part of the impact force, and the guide post 28 ensures the straightness of the motion trajectory, thereby reducing error accumulation. The precise fit between the insertion hole of the clamping plate 29 and the punching post further enhances the stability of the shearing process, making it suitable for mass production of high-precision sealing rings and improving overall processing efficiency and reliability.

[0045] Example 5:

[0046] In this embodiment, the workbench 2 is fixedly mounted on the frame 1. The translation mechanism 3 is disposed on the workbench 2 and includes a translation motor 5 and a moving platform 6. The translation motor 5 drives the moving platform 6 to translate along the slide rail 8 on the workbench 2 via a belt 7. A template 9 is fixedly mounted on the moving platform 6. The template 9 has a die hole 10 for placing the sealing ring plate to be punched. The first stamping mechanism 4 includes a first motor 11 and a first lifting platform 12. The first motor 11 drives the first lifting platform 12 to move up and down via a telescopic mechanism 13. The telescopic mechanism 13 consists of a screw and a nut. The nut is fixed to the first lifting platform 12. The rotation of the screw drives the nut to move linearly, thereby realizing the lifting and lowering of the first lifting platform 12. A first stamping plate 14 is fixedly mounted below the first lifting platform 12. The first stamping plate 14 is connected to a support column 15, and the support column 15 has a through hole 16. The workbench 2 is fixedly mounted with a support platform 18 via a column 17. A second stamping mechanism 19 is mounted on the support platform 18, including a second motor 20 and a second lifting platform 21. The second motor 20 drives the second lifting platform 21 to move up and down via a lead screw 22. A second stamping plate 23 and a third stamping plate 24 are fixedly mounted on the second lifting platform 21. The second stamping plate 23 is connected to a first cutting column 25, and the third stamping plate 24 is connected to a second cutting column 26. The through hole 16 of the support column 15 of the first stamping plate 14 is aligned with the axis of the first cutting column 25 of the second stamping plate 23, ensuring precise cooperation between the two during the stamping process.

[0047] In this embodiment, a first collecting hopper 31 is fixedly installed on the first lifting platform 12 and below the first stamping plate 14. A first material inlet 32 ​​is fixedly installed on the first collecting hopper 31. The first collecting hopper 31 is used to collect the edge material from the center area of ​​the cut sealing ring. The first material inlet 32 ​​can be connected to a negative pressure device to quickly suck away the edge material. In specific operation, the sealing ring plate is placed on the template 9 so that the sealing ring is aligned with the die hole 10. The translation mechanism 3 is activated, and the translation motor 5 drives the belt 7 to move the moving platform 6 along the slide rail 8, transferring the template 9 and the sealing ring plate on it to the area below the second stamping plate 23, so that the axis of the die hole 10 of the template 9 is aligned with the through hole 16 of the support column 15 and the axis of the first punching column 25. The first stamping mechanism 4 is activated, and the first motor 11 drives the first lifting platform 12 to move upward through the telescopic mechanism 13, causing the first stamping plate 14 and the support column 15 to support the sealing ring located at the die hole 10. The second stamping mechanism 19 is activated, and the second motor 20 drives the second lifting platform 21 to move downwards via the lead screw 22, causing the second stamping plate 23 and the first punching column 25 to press down, so that the first punching column 25 is inserted into the through hole 16 of the support column 15. The side wall of the first punching column 25 forms a shearing action with the inner wall of the through hole 16, cutting off the edge material in the central area of ​​the sealing ring. The cut edge material falls into the first collecting hopper 31 and is quickly sucked away by the negative pressure device connected to the first material interface 32, preventing the edge material from accumulating and affecting subsequent operations.

[0048] After the first stamping mechanism 4 and the second stamping mechanism 19 are reset, the translation mechanism 3 is restarted, transferring the template 9 and its sealing ring plate to below the third stamping plate 24, aligning the axis of the die hole 10 of the template 9 with the axis of the second punching post 26. The second stamping mechanism 19 is restarted, driving the third stamping plate 24 downward, so that the second punching post 26 is inserted into the die hole 10 of the template 9. The side wall of the second punching post 26 forms a shearing action with the inner wall of the die hole 10, cutting and separating the sealing ring from the sealing ring plate, completing the final punching of the sealing ring. Throughout the process, the first collecting hopper 31 continuously collects the edge material in the central area and sucks it away by negative pressure, ensuring the cleanliness of the punching area and improving work efficiency and product quality.

[0049] This embodiment, through the design of the first collecting hopper 31 and the first material interface 32, achieves rapid collection and removal of edge material, avoiding the tediousness and errors of manual cleaning and improving the degree of automation. Simultaneously, the fixed installation of the first collecting hopper 31 ensures its stability during the punching process, preventing displacement due to vibration or impact and guaranteeing punching accuracy. The negative pressure suction method further optimizes the working environment, reducing the impact of dust and waste on the equipment and extending its service life. The overall structure is compact, operation is simple, and it is suitable for mass production of sealing rings, significantly improving processing efficiency and product consistency.

[0050] Example 6:

[0051] In this embodiment, the workbench 2 has a discharge port 33 below the third stamping plate 24. A second collecting hopper 34 is fixedly installed on the discharge port 33, and a second discharge port 35 is fixedly installed on the second collecting hopper 34. The punched single sealing rings fall into the second collecting hopper 34 through the discharge port 33. The second discharge port 35 can be connected to negative pressure to quickly suck the sealing rings away. This structure is reasonably designed and can effectively collect and quickly transfer the punched sealing rings, improving production efficiency.

[0052] During the operation of the sealing ring punching machine, when the second punching mechanism 19 drives the third punching plate 24 to move downward, the second punching column 26 is inserted into the die hole 10 of the template 9. The side wall of the second punching column 26 forms a shearing action with the inner wall of the die hole 10, cutting and separating the sealing ring from the sealing ring plate. The punched single sealing ring falls out of the die hole 10 of the template 9. Since the worktable 2 has a discharge port 33 below the third punching plate 24, the sealing ring falls naturally into the discharge port 33 by gravity. The discharge port 33 is fixedly installed with a second collection hopper 34, which can collect the fallen sealing rings to prevent them from scattering or accumulating on the worktable 2, ensuring that the working area is clean and orderly. The second collection hopper 34 is fixedly installed with a second discharge port 35, which can be connected to a negative pressure system. The negative pressure suction will quickly suck the sealing rings away from the second collection hopper 34, realizing the automatic collection and transfer of the sealing rings.

[0053] In this embodiment, the location of the discharge port 33 precisely corresponds to the punching area of ​​the third stamping plate 24, ensuring that the punched sealing rings can accurately fall into the discharge port 33. The fixed installation method of the second collection hopper 34 ensures its stability and sealing performance, preventing the sealing rings from getting stuck or leaking during the collection process. The design of the second discharge port 35 facilitates connection to external negative pressure equipment, enabling rapid discharge of the sealing rings through negative pressure suction, avoiding manual intervention and improving the degree of production automation. The entire collection and transfer process is continuous and smooth, effectively reducing the processing time of the sealing rings after punching and improving the overall processing efficiency.

[0054] Through the implementation of this embodiment, the sealing ring punching machine can automatically collect and transfer the finished sealing rings to the next process after completing the punching operation, eliminating the need for manual picking and sorting, significantly reducing labor intensity, and ensuring the integrity and cleanliness of the sealing rings. This structure is simple, practical, and easy to maintain, suitable for large-scale production environments, and has good application prospects.

[0055] Example 7:

[0056] In this embodiment, a control panel 36 is fixedly installed on the workbench 2, and buttons 37 are fixedly installed on the control panel 36. The control panel 36 is located at the front of the workbench 2, facilitating operation while standing. The control panel 36 is made of metal plate with a non-slip surface. The buttons 37 are arranged on the inclined panel of the control panel 36 and are divided into multiple functional areas, including start, stop, emergency stop, and speed adjustment. The buttons 37 are waterproof and dustproof, ensuring long-term reliable use in rubber processing environments. By observing the positions of the template 9 and the sealing ring plate, the worker directly presses the corresponding button 37 to control the operation of the translation mechanism 3 and the punching mechanism, thereby completing the entire punching process. The design of the control panel 36 allows the worker to easily monitor and adjust the equipment without frequent movement, improving operational convenience and safety.

[0057] During the punching process, the worker first places the sealing ring plate on the template 9, ensuring that the sealing ring is aligned with the die hole 10. Then, the worker activates the translation mechanism 3 via button 37 on the operating table 36. The translation motor 5 drives the moving table 6 along the slide rail 8 via belt 7, transferring the template 9 and the sealing ring plate on it below the second stamping plate 23. At this time, the axis of the die hole 10 of the template 9 is aligned with the axis of the through hole 16 of the support column 15 of the first stamping plate 14 and the axis of the first punching column 25 of the second stamping plate 23. The worker presses button 37 again to activate the first stamping mechanism 4. The first motor 11 drives the first lifting platform 12 via telescopic mechanism 13, causing the first stamping plate 14 to move upward, so that the support column 15 supports the sealing ring located at the die hole 10. Next, the worker operates button 37 to activate the second stamping mechanism 19. The second motor 20 drives the second lifting platform 21 via lead screw 22, causing the second stamping plate 23 to move downward, so that the first punching column 25 is inserted into the through hole 16 of the support column 15. The sidewall of the first punching post 25 forms a shearing action with the inner wall of the through hole 16, cutting off the edge material in the central area of ​​the sealing ring. After this step is completed, the worker resets the first punching mechanism 4 and the second punching mechanism 19 by pressing button 37.

[0058] Subsequently, the worker continues to operate button 37, activating the translation mechanism 3 to move the template 9 and its sealing ring plate below the third stamping plate 24, aligning the axis of the die hole 10 of the template 9 with the axis of the second punching column 26. The worker presses button 37 again to activate the second stamping mechanism 19, driving the third stamping plate 24 downwards, causing the second punching column 26 to insert into the die hole 10 of the template 9. The side wall of the second punching column 26 forms a shearing action with the inner wall of the die hole 10, cutting and separating the sealing ring from the sealing ring plate. Throughout the process, the worker only needs to control each step in front of the operating table 36 via button 37, without manual intervention in the punching action, greatly reducing labor intensity while ensuring cutting accuracy and efficiency. The fixed installation of the operating table 36 and the reasonable layout of the buttons 37 make the equipment operation intuitive and simple, allowing even novice workers to quickly get started, effectively improving the overall automation level of the production line.

[0059] Furthermore, the design of the control panel 36 incorporates ergonomic principles, with the buttons 37 arranged in a clear sequence and displaying their functions, minimizing the possibility of misoperation. During extended production runs, workers can easily adjust punching parameters, such as translation speed or punching pressure, via the control panel 36 to accommodate the processing needs of different specifications of sealing rings. This design not only optimizes the workflow but also reduces the complexity of equipment maintenance, as the buttons 37 are directly connected to the control system, making troubleshooting and replacement more convenient. Overall, the integration of the control panel 36 and buttons 37 enables the sealing ring punching machine to achieve both high-efficiency production and user-friendly, reliable operation, making it suitable for large-scale industrial applications.

[0060] Example 8:

[0061] In this embodiment, a protective housing 38 is fixedly installed on the frame 1. The protective housing 38 has an inlet / outlet 39, and safety light curtains 40 are fixedly installed on both sides of the inlet / outlet 39. The protective housing 38 completely covers the punching area, forming a closed operating space, effectively isolating the external environment and preventing operators from accidentally contacting moving parts or splashing materials. The inlet / outlet 39 is designed to facilitate the installation and removal of sealing ring plates by operators. The safety light curtains 40 use photoelectric sensing technology to form an invisible beam barrier at the inlet / outlet 39. When an operator or foreign object enters the beam area, the light curtain immediately detects the obstruction signal and transmits the signal to the control system. The system then interrupts the execution of the punching program, ensuring timely shutdown of the equipment in dangerous situations. This protective structure is particularly suitable for high-speed punching operations, ensuring the continuity of the processing while minimizing safety hazards.

[0062] In practical implementation, the protective housing 38 is made of sheet metal, its structural strength capable of withstanding accidental impacts. The surface of the housing is treated with rust prevention to adapt to the humid environment of rubber processing sites. The dimensions of the inlet / outlet 39 are designed based on the maximum external shape of the sealing ring plate to ensure smooth material flow. The installation position of the safety light curtain 40 is precisely calculated so that its beam can completely cover the cross-section of the inlet / outlet 39, effectively identifying intrusion attempts from any direction. The light curtain system has a self-testing function, periodically checking the working status of the beam emitter and receiver to ensure the reliability of safety protection. When the light curtain triggers protection, the equipment will issue an audible and visual alarm, prompting operators to troubleshoot the abnormality. After the safety hazard is eliminated, the equipment can only be restarted via a dedicated reset button.

[0063] This protective device works in conjunction with other components of the punching machine. When the translation mechanism 3 moves the moving table 6 and template 9 into and out of the processing area, the protective housing 38 provides a safe operating path for the moving parts. When the first punching mechanism 4 and the second punching mechanism 19 perform punching operations, the protective housing 38 completely isolates the high-pressure punching area, preventing operators from accidentally entering the dangerous area. The response time of the safety light curtain 40 is precisely set, enabling it to interrupt the program at any time before the punching operation begins, providing comprehensive safety protection for the operator. This protective design not only meets the safety specifications for mechanical equipment but also significantly reduces the burden of manual monitoring through automated protection.

[0064] In practical applications, this protective system demonstrates significant safety benefits. Operators can conveniently load and unload materials through the inlet / outlet 39 without worrying about injury from sudden equipment startup. The sensitive detection of the safety light curtain 40 ensures that even the fastest intrusion is promptly identified, effectively preventing workplace accidents. Simultaneously, the protective enclosure 38 also provides sound insulation and noise reduction, improving the working environment. The entire protective system is deeply integrated with the punching machine's control system, achieving a unified approach to safety and production, ensuring both operator safety and stable production efficiency and product quality.
