Description

Technical Field

[0001] This invention relates to the field of metal stamping technology, and in particular to a manufacturing equipment for a wave deflector for oil tankers. Background Technology

[0002] As a core structural component of tank trucks, wave deflectors are typically made of sheet metal and installed inside the tank. They separate and buffer the liquid within the tank during vehicle movement, reducing the wave impact caused by liquid sloshing and thus playing a role in stabilizing the flow. This helps reduce the risk of traffic accidents such as rollovers and rear-end collisions caused by liquid inertia. Wave deflectors are usually designed with various circular holes, including manholes, oil passages, and vents. The flanged structure at the manhole helps enhance the local rigidity of that location, reducing deformation and cracking.

[0003] However, the manufacturing process of wave-damping plates often employs a stamping process on metal sheets. Because wave-damping plates have numerous and complexly distributed holes, the metal sheet requires multiple positioning and repetitive operations during stamping. This not only increases the complexity of the process but also restricts processing efficiency, affecting the manufacturing quality and consistency of the wave-damping plates. Summary of the Invention

[0004] To address the aforementioned problems, this application provides a manufacturing equipment for wave deflectors used in oil tankers.

[0005] This application provides a manufacturing equipment for wave deflectors for oil tankers, which adopts the following technical solution:

[0006] A manufacturing equipment for a wave deflector for an oil tanker includes:

[0007] A first stamping device is used to stamp and flange a metal plate to form a first hole and a flange structure. The first stamping device has a first state and a second state.

[0008] The second stamping device is used to stamp the metal plate to form a second hole, the second hole being distributed circumferentially with the central axis of the first hole as the axis;

[0009] Wherein, when the first stamping device is in the first state, it is used to stamp and flang the metal plate, and when it is in the second state, the metal plate can rotate relative to the first stamping device.

[0011] Preferably, the grinding mechanism includes a cutting component for scraping the edges of the flange structure when the metal plate rotates relative to the first stamping device.

[0012] Preferably, the cutting assembly includes a blade holder and at least two oppositely arranged cutting blades that enclose a cutting space;

[0013] When the first stamping device is in the second state, at least a portion of the flange structure is located within the cutting space and is in contact with the cutter.

[0014] The cutter is slidably disposed on the blade holder, and a first elastic element is provided between the blade holder and the cutter. The first elastic element is used to make the cutter tend to move toward the cutting space.

[0015] Preferably, the polishing mechanism further includes a friction component, which is used to perform friction polishing on the flange structure when the metal plate rotates.

[0016] Preferably, the friction assembly includes a housing and an inflatable bladder disposed within the housing, wherein the outer wall of the inflatable bladder is provided with a sandpaper layer;

[0017] The housing is provided with a grinding cut. When the first stamping device is in the second state, at least a portion of the flange structure is located within the grinding cut, and the inflatable bladder covers the flange structure when it is inflated.

[0018] Preferably, the inflatable bladder is movably disposed within the housing and can move within the housing when sliding and rubbing against the flange structure.

[0019] Preferably, it also includes a frame, the first stamping device includes an upper die and a lower die, the frame is disposed on the upper die, the grinding mechanism is movably disposed on the frame, and a second elastic member is provided between the frame and the grinding mechanism, the second elastic member being used to make the grinding mechanism tend to move toward the lower die.

[0020] Preferably, the frame is connected to a connecting rod, the connecting rod is slidably engaged with the upper mold, and a third elastic element is provided between the connecting rod and the upper mold, the third elastic element being used to give the connecting rod a tendency to move towards the lower mold side;

[0021] The connecting rod is configured to contact the lower die when the first stamping device is in a first state, so as to separate the grinding mechanism from the flanging structure; when the first stamping device is in a second state, the connecting rod moves towards the lower die side under the action of the third elastic member, so as to contact the grinding mechanism with the flanging structure.

[0022] Preferably, it also includes a frame, and a compression bladder is provided between the frame and the grinding mechanism, and the compression bladder and the inflatable bladder are connected by a pipe;

[0023] The compression bladder is configured such that, when the first stamping device is in the second state, gas inside the compression bladder enters the inflation bladder under the push of the grinding mechanism, so that the inflation bladder can cover the flange structure when the first stamping device is in the second state.

[0024] The present invention has the following advantages and beneficial effects:

[0025] By rotating the metal plate while the first stamping device is in its second state, different areas of the metal plate can be sequentially aligned with the second stamping device, thereby forming a second hole on the metal plate based on the first hole. Thus, only one positioning operation is required when machining the first hole, and the machining of the second hole can be completed by rotating the metal plate based on this positioning, eliminating the need for repeated positioning operations during subsequent hole machining. This simplifies the stamping process, maintains the continuity of the process, and helps to reduce process complexity, improve processing efficiency, and contribute to achieving a more stable and consistent manufacturing effect.

[0038] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be described in detail below. Obviously, the described embodiments are merely some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0039] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0040] Reference Figure 1 , Figure 2This application provides an apparatus for manufacturing a baffle plate for oil tankers, used to stamp a metal plate 10 to manufacture a baffle plate for the inside of an oil tanker. The apparatus includes a first stamping device 100 and a second stamping device 200. In some embodiments, the first stamping device 100 is used to stamp a first hole 11 and a corresponding flange structure 13 on the metal plate 10 (in conjunction with...). Figure 9 As shown, the flange structure 13 can increase the local stiffness at the location of the first hole 11 to a certain extent, making the area more suitable for resisting deformation and reducing the risk of cracking during use. The second stamping device 200 is used to stamp the second hole 12 on the metal plate 10.

[0041] For example, refer to Figure 9 The first hole 11 can be a manhole, typically used for maintenance and operation inside tank trucks. Manholes are relatively large and are fitted with a flanged structure 13 to improve the strength and stability around the hole. The second hole 12 can be an oil passage or a vent. The oil passage provides a channel for liquid flow between the two sides of the baffle plate, while the vent helps to balance the internal pressure distribution of the tank. By distributing oil passages or vents circumferentially around the manhole, the baffle plate can meet structural strength requirements while also accommodating the needs of liquid flow and gas exchange.

[0042] It should be understood that the "flanged structure 13" refers to the flange structure formed integrally with the hole wall after the metal plate 10 is punched through a stamping process. The presence of this structure helps to improve the structural strength around the hole.

[0043] In some embodiments, the first stamping device 100 has a first state and a second state. When the first stamping device 100 is in the first state, it is used to stamp and flang the metal plate 10. When it is in the second state, the metal plate 10 can rotate relative to the first stamping device 100.

[0044] In the first state, the metal plate 10 can be fixed in position with the first stamping device 100 for stamping and flanging to form the first hole 11 and the flanging structure 13. When the first stamping device 100 switches to the second state, the metal plate 10 can rotate relative to the first stamping device 100, and different areas of the metal plate 10 can be rotated sequentially to the corresponding positions of the second stamping device 200. Through this relative rotation, the second stamping device 200 can process multiple second holes 12 on the metal plate 10 based on the central axis of the first hole 11 as a reference.

[0045] In some embodiments, refer to Figure 9The second holes 12 are distributed circumferentially with the central axis of the first hole 11 as the axis. Therefore, during processing, the metal plate 10 only needs to be positioned once when forming the first hole 11. When forming multiple second holes 12, the corresponding stamping can be completed by rotating based on this positioning, without needing to reposition for each stamping. This processing method helps to reduce the complexity of the process caused by multiple positioning, making the stamping process more continuous, and also helps to improve processing efficiency and obtain a more consistent wave-damping plate manufacturing effect.

[0046] It should be understood that the terms "first state" and "second state" are used to characterize the functional changes of the first stamping device 100 under different operating conditions. The first state corresponds to the metal plate 10 being fixed for stamping and flanging, while the second state corresponds to the condition where the metal plate 10 can rotate relative to the device. The definitions of these terms provide a clearer understanding of the structure and processing method in this embodiment.

[0047] For example, the first stamping device 100 may include an upper die 110 and a lower die 120. When the first stamping device 100 is in a first state, the upper die 110 and the lower die 120 are closed, thereby stamping the metal plate 10 to form a first hole 11 and a flange structure 13. When the first stamping device 100 is in a second state, the upper die 110 moves a certain distance away from the lower die 120 relative to the lower die 120, so that the upper die 110 and the lower die 120 are kept apart. At this time, the upper die 110 and the lower die 120 are not completely separated, but the flange structure 13 of the metal plate 10 is constrained between the upper die 110 and the lower die 120 in a clamping manner. Since the upper die 110 and the lower die 120 are in a relatively separated state, no excessive clamping force is applied to the metal plate 10, thereby allowing the metal plate 10 to rotate relative to the first stamping device 100 while maintaining its positioning. During the rotation of the metal plate 10, the cooperation between the flange structure 13 and the upper mold 110 and lower mold 120 helps to maintain positioning accuracy and makes the progress control of the metal plate 10 during rotation more stable.

[0048] It should be understood that when the first stamping device 100 is in the second state, the upper die 110 moves a certain distance away from the lower die 120 relative to the lower die 120, so as to allow the metal plate 10 to rotate relative to it while clamping it. The moving distance can be determined according to specific process requirements and structural conditions, and this application does not limit it.

[0049] In some embodiments, refer to Figure 1 , Figure 3It also includes a grinding mechanism 300, which is configured to contact the flanging structure 13 when the first stamping device 100 is in the second state, and to grind the flanging structure 13 when the metal plate 10 rotates. By providing the grinding mechanism 300 during rotation, the edge of the hole wall of the flanging structure 13 can be processed to remove burrs or sharp protrusions formed at the edge due to the plastic deformation of the material during the stamping process.

[0050] It is understandable that during the process of forming the flange structure 13 by the first stamping device 100, burrs or uneven edges are often generated at the edge area of ​​the flange structure 13 due to the local compression and stretching of the metal material. If these burrs are not treated, they may pose safety hazards during subsequent use. By setting a grinding process simultaneously during the stamping process, the need for subsequent additional deburring processes can be reduced to a certain extent, making the overall processing steps more compact and improving the continuity and efficiency of the manufacturing process.

[0051] In some embodiments, the grinding mechanism 300 includes a cutting assembly 310 for scraping the edges of the flanging structure 13 when the metal plate 10 rotates relative to the first stamping device 100. Exemplarily, the cutting assembly 310 may include a blade holder 311 and at least two opposing cutters 312, the cutters 312 forming a cutting space 313. When the flanging structure 13 enters the cutting space 313 during rotation, its edges contact the cutting edges of the cutters 312, thereby gradually removing burrs or sharp edges formed during stamping.

[0052] By setting the cutting component 310, the sharp edges of the flange structure 13 can be trimmed, making its edges gradually smoother. This reduces the risk of scratches to operators or installers during subsequent use. Simultaneously, because the flange edges are scraped, their surface is relatively smoother, which improves installation efficiency during the installation of the wave-damping plate.

[0053] It should be understood that the "scraping" mentioned in this application does not refer to the complete removal of the edge of the flange structure 13 in one go, but rather that the cutter 312 remains in contact with the edge of the flange structure 13 during the rotation of the metal plate 10, so that the edge is gradually reduced under the action of rotational motion. Specifically, when the metal plate 10 rotates around its center, the edge of the flange structure 13 will undergo relative friction and cutting action with the cutting edge of the cutter 312 in each revolution, thereby removing local protrusions or burrs on the flange edge layer by layer.

[0054] This gradual scraping method helps to improve the flatness of the flanged edge to a certain extent, making the flanged structure 13 less prone to local bulges caused by burr residue. On the other hand, the gradual reduction process can also reduce the impact of a single force on the flanged structure 13 to a certain extent, thereby reducing irregular deformation that may be caused by excessive force concentration.

[0055] Thus, after the first hole 11 is processed, the metal plate 10 can be positioned using a single positioning process. During the processing of the second hole 12, different areas of the metal plate 10 can be rotated sequentially under the second stamping device 200, thereby achieving the stamping forming of multiple second holes 12. Simultaneously, during the rotation of the metal plate 10, the flanging structure 13 remains in contact with the cutting assembly 310, thereby gradually scraping the edges of the flanging structure 13 under rotational motion. This not only reduces the complexity of the process caused by repeated positioning to a certain extent but also improves the edge condition of the flanging structure 13 to a certain extent, thereby improving both processing efficiency and processing quality.

[0056] In some embodiments, refer to Figure 3 , Figure 4 The cutting assembly 310 includes a blade holder 311 and at least two opposing cutters 312, the cutters 312 forming a cutting space 313; when the first stamping device 100 is in the second state, at least a portion of the flange structure 13 is located in the cutting space 313 and in contact with the cutters 312; the cutters 312 are slidably disposed on the blade holder 311, and a first elastic member 314 is provided between the blade holder 311 and the cutters 312, the first elastic member 314 being used to give the cutters 312 a tendency to move toward the cutting space 313.

[0057] With this structure, the cutter 312 can continuously adhere to the edge of the flange structure 13 under the elastic force of the first elastic element 314, and gradually scrape the edge as the metal plate 10 rotates. This facilitates the removal of burrs from the flange edge to a certain extent, improving the flatness of the flange edge; on the other hand, the elastic force provided by the elastic element can buffer the force between the cutter 312 and the flange structure 13 to a certain extent, reducing irregular deformation caused by excessive force concentration.

[0058] In some embodiments, refer to Figure 4 , Figure 5The contact area between the cutter 312 and the flange structure 13 can be designed as a bevel or an arc. When the flange structure 13 enters the cutting space 313 and contacts the cutter 312, the bevel or arc can guide the cutter 312 to move away from the flange structure 13 to a certain extent, causing a certain separation tendency between the relatively arranged cutters 312. Through this design, the cutter 312 can automatically adjust its position according to the specific shape and position of the flange structure 13, thereby improving the adaptability between the cutter 312 and the flange structure 13. At the same time, the first elastic element 314 generates a restoring force after the cutter 312 moves away, causing the cutter 312 to move back towards the cutting space 313, achieving the functions of fitting and following. This is beneficial in maintaining a stable scraping state during the continuous contact between the flange structure 13 and the cutter 312, and can also reduce the possibility of rigid collisions to a certain extent, thereby reducing the risk of damage to the cutting edge of the cutter 312 or the flange structure 13.

[0059] In some embodiments, refer to Figure 6 , Figure 7 The grinding mechanism 300 also includes a friction component 320, which is used to perform friction grinding on the flange structure 13 when the metal plate 10 rotates. When the first stamping device 100 is in the second state, the metal plate 10 can rotate relative to the first stamping device 100. During the rotation of the metal plate 10, the flange structure 13 comes into contact with the friction component 320 along with the movement of the metal plate 10, thereby generating relative friction. Through this relative movement, the friction component 320 can gradually grind the surface of the flange structure 13, making the surface of the flange structure 13 smoother and more even. By removing the small burrs or protrusions formed during the stamping and flangening process through friction, it is beneficial to improve the processing quality of the flange edge on the one hand, and on the other hand, it reduces the risk of personnel being scratched by the flange edge during subsequent installation or use to a certain extent.

[0060] In some embodiments, refer to Figure 7 , Figure 8 The friction assembly 320 includes a housing 321 and an inflatable bladder 322 disposed within the housing 321. The outer wall of the inflatable bladder 322 is provided with a sandpaper layer. The housing 321 is provided with a sanding cut 323. When the first stamping device 100 is in the second state, at least a portion of the flange structure 13 is located within the sanding cut 323, and the inflatable bladder 322 covers the flange structure 13 when it is inflated.

[0061] When the first stamping device 100 is in the second state, the metal plate 10 can rotate relative to the first stamping device 100. During the rotation, the flange structure 13 enters the grinding cut 323 and contacts the outer wall of the inflatable bladder 322. When the inflatable bladder 322 is inflated, its outer wall can deform to a certain extent, thereby covering the outer surface of the flange structure 13. Through this covering contact, the sandpaper layer can adhere tightly to the flange structure 13 and continuously rub and grind its surface. Because the inflatable bladder 322 has a certain degree of flexibility and deformability, it can adapt to the shape and size differences of the flange structure 13 to a certain extent, thereby making the grinding process more uniform and reducing the risk of damage caused by excessive local pressure. In this way, burrs or irregular protrusions on the surface of the flange structure 13 can be effectively reduced, making the surface more flat and smooth, which is beneficial for subsequent installation and reduces the risk of scratches to personnel from the flange edge during use to a certain extent.

[0062] In some embodiments, the sandpaper polishing layer is detachably fixed to the outer wall of the inflatable bladder 322, for example, by means of an adhesive layer or Velcro. Since the sandpaper polishing layer gradually wears down or fails due to prolonged friction during use, a detachable structure allows for replacement after the polishing layer wears out, without requiring the replacement of the entire inflatable bladder 322. This not only facilitates maintenance and reduces costs but also allows for flexible replacement of sandpaper polishing layers with different grits according to processing needs, thereby improving the adaptability of polishing and processing quality to a certain extent.

[0063] In some embodiments, refer to Figure 7 , Figure 8 The inflatable bladder 322 is movably disposed within the housing 321 and can move within the housing 321 during sliding friction with the flange structure 13. "Movable" means that the inflatable bladder 322 is not fixed within the housing 321, but can change position within a certain range under the action of friction, for example, by slightly sliding along the inner wall of the housing 321. When the metal plate 10 rotates relative to the first stamping device 100, the flange structure 13 enters the grinding cut 323 and contacts the outer wall of the inflatable bladder 322. During continuous friction, the inflatable bladder 322 can gradually move within the housing 321, allowing the flange structure 13 to sequentially contact different areas of the outer wall of the inflatable bladder 322. In this way, it can, to a certain extent, avoid the situation where only the same fixed area of ​​the inflatable bladder 322 contacts the flange structure 13, leading to excessively rapid local wear, thereby extending the overall service life of the inflatable bladder 322. Simultaneously, the grinding surfaces of different areas can work alternately, making the grinding effect relatively uniform and stable, which is beneficial to improving processing quality.

[0064] In some embodiments, refer to Figure 5 , Figure 7 The housing 321 can be integrally formed with the tool holder 311, meaning the housing 321 is a component of the tool holder 311. The housing 321 encloses the inflatable bladder 322 within it, thereby restricting the deformation direction of the inflatable bladder 322. This ensures that the inflatable bladder 322 expands and deforms only in the direction towards the grinding cut 323, allowing it to cover the flange structure 13 when the metal plate rotates. Specifically, the housing 321 is a housing structure with an opening, which is the grinding cut 323. When the inflatable bladder 322 is inflated, because the housing 321 provides constraint in directions other than the grinding cut 323, the expansion of the inflatable bladder 322 tends to concentrate at the grinding cut 323. Therefore, during the process of the flange structure 13 entering the grinding cut 323, the inflatable bladder 322 can adhere to the surface of the flange structure 13 in a certain degree of covering manner, achieving uniform friction grinding.

[0065] Through this structure, the shell 321 can effectively guide the deformation direction of the inflatable bladder 322, so that the grinding force is concentrated on the flange structure 13, avoiding the deformation of the inflatable bladder 322 in unnecessary directions, thus improving the stability and consistency of the grinding process to a certain extent.

[0066] In some embodiments, refer to Figure 1 , Figure 8 It also includes a frame 400. The first stamping device 100 includes an upper die 110 and a lower die 120. The frame 400 is disposed on the upper die 110. The grinding mechanism 300 is movably disposed on the frame 400, and a second elastic element 500, such as a compression spring or an elastic washer, is provided between the frame 400 and the grinding mechanism 300. The second elastic element 500 is used to give the grinding mechanism 300 a tendency to move toward the lower die 120.

[0067] When the first stamping device 100 is in the second state, the flanging structure 13 contacts the grinding mechanism 300. The presence of the second elastic element 500 allows the grinding mechanism 300 to generate a certain elastic displacement during the contact process, thereby maintaining an adaptive contact relationship between the grinding mechanism 300 and the flanging structure 13. In this way, on the one hand, overly rigid collisions between the two can be avoided, and on the other hand, the contact force can be buffered and adjusted to a certain extent, which is beneficial to stabilizing the grinding process and improving the uniformity and reliability of grinding.

[0068] In some embodiments, refer to Figure 4 , Figure 5The frame 400 is connected to a connecting rod 600, which slides in conjunction with the upper die 110. A third elastic element 700 is provided between the connecting rod 600 and the upper die 110, which is used to give the connecting rod 600 a tendency to move towards the lower die 120. Specifically, the connecting rod 600 is configured to contact the lower die 120 when the first stamping device 100 is in a first state, so that the grinding mechanism 300 separates from the flanging structure 13; when the first stamping device 100 is in a second state, the connecting rod 600 moves towards the lower die 120 under the action of the third elastic element 700, so that the grinding mechanism 300 contacts the flanging structure 13.

[0069] The movement of the connecting rod 600 can be divided into two situations: When the first stamping device 100 is in the first state, the upper die 110 and the lower die 120 are in the mold-closed position, and the connecting rod 600 is in contact with the lower die 120. Under the blocking action of the lower die 120, the connecting rod 600 is forced to move away from the lower die 120, and through its connection with the frame 400, it drives the grinding mechanism 300 away from the flanging structure 13. At this time, the metal plate 10 is stamped and formed in the first stamping device 100, and the grinding mechanism 300 will not come into contact with the metal plate 10, thereby avoiding damage to the grinding mechanism 300 and the metal plate 10 due to rigid collision to a certain extent.

[0070] When the first stamping device 100 is in the second state, the upper die 110 moves upward relative to the lower die 120 by a certain distance, causing the connecting rod 600 to separate from the lower die 120. Under the action of the third elastic element 700, the connecting rod 600 is pushed towards the lower die 120, and further drives the grinding mechanism 300 to move closer to the lower die 120, thereby causing the grinding mechanism 300 to contact the flanging structure 13. In this state, the metal plate 10 can rotate relative to the first stamping device 100, and the flanging structure 13 contacts and is processed by the grinding mechanism 300 during the rotation.

[0071] Through the cooperation of the connecting rod 600 and the third elastic element 700, the grinding mechanism 300 can automatically switch between different working stages: the grinding mechanism 300 is separated in the stamping stage, and can contact the flanging structure 13 in the rotary grinding stage. This structural design is conducive to improving the working reliability and processing efficiency of the equipment.

[0072] For example, the first elastic element 314, the second elastic element 500, and / or the third elastic element 700 can be spring structures, such as compression springs or tension springs. Utilizing the compressible or stretchable characteristics of the springs, the cutter 312, the grinding mechanism 300, and the connecting rod 600 can generate a tendency to move in a predetermined direction under stress, thereby achieving contact or separation with the flange structure 13.

[0073] In practical applications, other components with elastic recovery characteristics can also be selected as needed, such as elastic gaskets, rubber blocks, or air bladders. This application does not limit the specific form of the elastic component.

[0074] In some embodiments, refer to Figure 4 , Figure 8 It also includes a frame 400, a compression bladder 800 disposed between the frame 400 and the grinding mechanism 300, and a connection between the compression bladder 800 and the inflation bladder 322 via a pipe 810. The compression bladder 800 is configured such that, when the first stamping device 100 is in the second state, the gas inside the compression bladder 800 enters the inflation bladder 322 under the push of the grinding mechanism 300, so that the inflation bladder 322 can cover the flange structure 13 when the first stamping device 100 is in the second state.

[0075] The compression bladder 800 can be structurally a flexible bag, forming a deformable gas space inside. When the first stamping device 100 is in the second state, the flanging structure 13 contacts the grinding mechanism 300, and the flanging structure 13 pushes the grinding mechanism 300 to move towards the upper mold 110. During this process, the grinding mechanism 300 compresses the compression bladder 800, causing the gas inside the compression bladder 800 to be transmitted to the inflatable bladder 322 via the pipe 810. Thus, when the first stamping device 100 is stably maintained in the second state, the inflatable bladder 322 has been replenished with gas and is in an inflated state. Therefore, during the process of the flanging structure 13 entering the grinding cut 323, the inflatable bladder 322 contacts the flanging structure 13 in a certain degree of covering manner, which facilitates relatively uniform friction grinding when the metal plate 10 rotates.

[0076] Through this structure, the compression and recovery of the compression bladder 800 during the movement of the grinding mechanism 300 enables passive gas transfer and replenishment, allowing the inflatable bladder 322 to maintain its inflated state without the need for an additional independent gas source. This simplifies the overall structure of the device to a certain extent, and is beneficial to improving the system's integration and processing efficiency. This application does not limit the specific material and shape of the compression bladder 800, and it can be made of rubber, silicone, or other materials with elasticity and airtightness.

[0077] In some embodiments, refer to Figure 8The inflatable bladder 322 is connected to the pipe 810 via a ball joint, allowing the inflatable bladder 322 to rotate relative to the shell 321. This structure allows the inflatable bladder 322 to rotate at a certain angle when the flange structure 13 contacts the sandpaper-polished layer of the inflatable bladder 322 during rotation, thus continuously changing the surface position of the inflatable bladder 322. This avoids the problem of excessively rapid localized wear caused by the same contact area always participating in polishing. This can extend the service life of the inflatable bladder 322 and the sandpaper-polished layer to a certain extent and helps maintain the uniformity of the polishing effect.

[0078] In some embodiments, refer to Figure 1 , Figure 2 The distance between the first stamping device 100 and the second stamping device 200 is adjustable. Through this adjustable structural design, the relative positions of the first stamping device 100 and the second stamping device 200 can be adjusted according to the size of different metal plates 10 or the processing requirements of different wave-damping plates. In this way, during processing, after the first stamping device 100 completes the processing of the first hole 11 and the flange structure 13, the metal plate 10 can rotate more smoothly to the processing position of the second stamping device 200, thus facilitating the stamping of the second hole 12 in the target area of ​​the metal plate 10. This adjustable distance design, on the one hand, is beneficial for adapting to the manufacturing needs of wave-damping plates of different specifications, and on the other hand, improves the applicability and flexibility of the device in actual production applications.

Any changes or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of protection of the present invention.
