Technical Field

[0001] This invention relates to the field of sheet metal bending technology, specifically to a sheet metal bending machine for processing stainless steel sheets. Background Technology

[0002] Sheet metal bending machines typically combine mechanical, hydraulic, electrical, and computer control technologies. The operator first places the stainless steel sheet on the worktable, positions it using the back gauge, selects the appropriate die according to processing requirements, and installs it on the slide block and worktable. Then, the operator inputs bending parameters, such as bending angle and depth, into the CNC system. The CNC system generates control commands to start the hydraulic pump, and hydraulic oil enters the hydraulic cylinder, driving the slide block to move the upper die downwards, applying pressure to the sheet metal and causing it to undergo plastic deformation under the action of the lower die. After bending is complete, the slide block returns to its initial position.

[0003] Currently, existing stainless steel sheet bending machines tend to leave metal shavings on the surface of the equipment during operation, which affects the efficiency of subsequent operations. Therefore, a new design has been developed to address this issue. Summary of the Invention

[0004] To address the above problems, the present invention provides the following technical solution: a sheet metal bending machine for processing stainless steel sheets, comprising a bending device, wherein a pushing mechanism is fixedly connected inside the bending device; The bending device includes a bending base, a support frame fixedly connected to the top of the bending base, a bending frame body fixedly connected to the edge of the top of the support frame, and a bending table fixedly connected to the middle of the top of the support frame. A bearing mechanism is fixedly connected to the bottom of the groove inside the bending table. The bearing mechanism acts as a buffer during the downward compression process, thereby reducing the impact of external pressure on the components, dispersing compressive stress, protecting the core structure of the support table, preventing "bottom crushing" or "local deformation" of the workpiece, reducing bending springback and angular deviation, improving equipment stability, reducing safety hazards, and suppressing vibration and noise, thereby reducing mechanical stress between components. Wear and tear are reduced, and rigid collisions between components are minimized, thus providing a certain degree of protection. After prolonged operation, debris easily accumulates on the equipment surface. The top center of the bending table is fixedly connected to the bottom of the pushing mechanism. The pushing mechanism pushes the bent sheet metal to remove the material, reducing manual disassembly, lowering safety hazards associated with manual operation, improving equipment efficiency, preventing severe wear on components after prolonged operation, preventing impact on component performance, avoiding damage to critical components from manual material handling, preventing collision deformation, scratches, or contamination, avoiding abnormal load caused by manual intervention, eliminating the "high-risk operation risk" of manual material handling, avoiding the risk of "mold clamping," and keeping it away from high-pressure operating areas to reduce "sheet metal falling" and "scratches." To mitigate risks, stabilize the material handling process, shorten the work cycle, reduce equipment downtime, avoid interference from manual material handling with subsequent processing, and prevent positioning deviations caused by manual touch, a pneumatic device is fixedly connected to one side of the top of the bending table. This device flushes one side of the protective table, cleaning impurities from the component surface, reducing debris buildup, and preventing damage to the sheet metal during extrusion, thus ensuring the integrity of the sheet metal. This also removes impurities from the worktable, ensures bending accuracy, avoids the risk of "workpiece crushing," protects equipment components, extends service life, reduces "die wear," reduces "mechanical jamming" problems, improves the operating environment, reduces safety hazards, prevents "spatial debris" injuries, and reduces hazards caused by "oil buildup." A hydraulic column is fixedly connected to the middle of the top of the bending frame, and a buffer mechanism is fixedly connected to the bottom of the hydraulic column. This buffer mechanism acts as a shock absorber, reducing the compressive force, preventing excessive compression of components, preventing excessive damage to components, buffering instantaneous impacts, protecting core components of the equipment, reducing the load on the transmission system, optimizing the bending process, improving workpiece quality, avoiding "overpressure damage" to the workpiece, reducing "springback error," reducing the risk of equipment malfunctions, ensuring operational safety, preventing "overload protection false triggering," reducing the risk of "component detachment," and thus extending the service life of the equipment. An auxiliary rod is slidably connected to the top of the bending frame near the hydraulic column. When the sheet metal is placed on the bending table, the hydraulic column drives the buffer mechanism to compress the auxiliary rod.The auxiliary rod drives the bending block to press against the bearing mechanism, thereby bending the sheet metal. The bending block is fixedly connected to the outer side of the auxiliary rod near the bending table.

[0005] Preferably, the buffer mechanism includes a buffer housing, a sliding block slidably connected to the inner side of the buffer housing, a groove formed on the inner side of the buffer housing, and an outer block fixedly connected to the outer side of the sliding block. The outer side of the outer block is slidably connected to the inner wall of the groove, thereby limiting the sliding range of the component, preventing excessive sliding of the component, and providing a certain protective effect on the component. The buffer pad increases the wear resistance of the component, thereby reducing wear between components and extending the service life of the component. A buffer pad is fixedly connected to the outer side of the buffer housing near the bending block, and a first spring is fixedly connected to the bottom of the inner wall of the buffer housing, thereby playing a shock absorption and buffering role, reducing the squeezing force, preventing excessive squeezing of the component, preventing excessive damage to the component, buffering instantaneous impact, protecting the core components of the equipment, reducing the load on the transmission system, optimizing the bending process, improving the quality of the workpiece, avoiding "overpressure damage" to the workpiece, reducing "springback error", reducing the risk of equipment malfunction, ensuring operational safety, preventing "overload protection false triggering", reducing the risk of "component detachment", and thus extending the service life of the equipment. The outer side of the first spring is fixedly connected to the outer side of the sliding block.

[0006] Preferably, the bearing mechanism includes a bearing housing, with a damping rod slidably connected inside the bearing housing to provide shock absorption and buffering, thereby reducing the impact of external pressure on the components, dispersing compressive stress, protecting the core structure of the bearing platform, and preventing the bending platform from causing "bottom crushing" or "local deformation" of the workpiece, as well as body deformation and cracking. A cylindrical groove is formed in the middle of the interior of the bearing housing, and a protective mechanism is fixedly connected to the inner wall of the cylindrical groove. The protective mechanism reduces "bending springback" and "angle deviation", improves equipment stability, reduces safety hazards, and suppresses "vibration and noise", thereby reducing mechanical wear between components and reducing rigid collisions between components, thus providing a certain degree of protection for the components.

[0007] Preferably, the protective mechanism includes a second spring, which serves as a shock absorber and buffer, thereby reducing the impact of external pressure on the components, dispersing compressive stress, protecting the core structure of the bearing platform, preventing the workpiece from being "crushed at the bottom" or "locally deformed" on the bending platform, reducing "bending springback" and "angle deviation", improving equipment stability, reducing safety hazards, and suppressing "vibration and noise", thereby reducing mechanical wear between components and reducing rigid collisions between components, thus providing a certain protective effect on the components. One side of the second spring is fixedly connected to the bottom of the inner wall of the cylindrical groove, and the other side of the second spring is fixedly connected to a connecting rod. The outer side of the connecting rod is slidably connected to the inner side of the cylindrical groove, and a protective plate is fixedly connected to the outer side of the connecting rod away from the second spring.

[0008] Preferably, the pneumatic device includes a pneumatic frame, with a fan fixedly connected to the inner side of the frame and a grating plate fixedly connected to the outer side of the frame to prevent external impurities from entering, avoiding impurities from settling on the fan surface, preventing excessive accumulation of impurities, avoiding affecting the fan rotation, and preventing affecting the operating efficiency of the components. A grating cover is fixedly connected to the outer side of the frame away from the grating plate, and a rotating mechanism is fixedly connected to the inner wall of the grating cover. The air force washes the surface of the bending table, thereby cleaning impurities on the surface of the components, reducing debris retention, preventing debris from damaging the sheet metal during the extrusion process, thus ensuring the integrity of the sheet metal, removing impurities from the worktable, ensuring bending accuracy, avoiding the risk of "workpiece crushing", protecting equipment components, extending service life, reducing "die wear", reducing "mechanical jamming" problems, improving the operating environment, reducing safety hazards, avoiding "scratching debris" injuries, and reducing the hazards caused by "oil accumulation".

[0010] Preferably, the rotating mechanism includes a fixed frame, the outer side of which is fixedly connected to the inner wall of the grille cover. A connecting shaft is rotatably connected to the inner side of the fixed frame. A fan is fixedly connected to one side of the connecting shaft, and a scraper is fixedly connected to the side of the connecting shaft away from the fan. This achieves the function of cleaning impurities from the component surface, promoting the outward discharge of impurities, preventing excessive accumulation of impurities, preventing blockage of surface holes in the component, avoiding affecting airflow, restoring ventilation channels, ensuring the "exhaust efficiency" of the fan, removing "physical blockages" from the grille gaps, preventing airflow attenuation, removing "sticky contaminants" from the grille surface, preventing airflow turbulence, protecting core components, and extending equipment life. To reduce pollutants entering the fan, decrease internal dirt accumulation and corrosion, ensure safety and protection, avoid risks to personnel and equipment, prevent grille deformation and breakage, prevent accidental contact, prevent accelerated grille corrosion, and prevent structural failure, a silicone block is fixedly connected to the outer side of the scraper near the grille cover.

[0011] Preferably, the pushing mechanism includes a slide rail, with a pushing housing slidably connected to the top of the slide rail.

This reduces manual disassembly, lowers the safety hazards of manual operation, and improves the operating efficiency of the equipment. A support block is inserted into the inner side of the pushing housing, and a pushing plate is inserted into the outer side of the support block away from the pushing housing. This facilitates disassembly and installation, prevents severe wear of components after prolonged operation, avoids affecting the operating effect of components, avoids damage to key components of the equipment caused by manual material handling, prevents collision deformation, scratches, or contamination, avoids abnormal load caused by manual intervention, eliminates the "high-risk operation risk" of manual material handling, avoids the risk of "mold clamping," keeps away from high-pressure operating areas, reduces the risk of "sheet metal falling" and "scratching," stabilizes the material handling process, shortens the operation cycle, reduces equipment downtime, avoids interference of manual material handling with subsequent processing, and avoids positioning deviation caused by manual touch.

[0012] Preferably, a soft rubber block is fixedly connected to the side of the push plate away from the support block to increase the wear resistance and cushioning effect of the component surface, thereby reducing rigid collisions between components, reducing wear between components, extending the service life of the components, and reducing damage to the push components. The soft rubber block has a cutout on the side away from the push plate to further improve the cushioning effect of the component. Secondly, the cutout increases the surface texture of the component, thereby providing a certain protective effect and improving the pushing effect of the component.

[0013] Preferably, the inner side of the support block has a groove, and a third spring is fixedly connected to the inner wall of the groove. A protrusion is fixedly connected to one side of the third spring. Protrusions are provided on both sides of the support block. The support block is inserted into the inner side of the push housing. The protrusions are squeezed and contracted by the surface of the component. The protrusions are connected to the outer housing to fix the component. The outer side of the protrusions is slidably connected to the inner side of the groove. The two sides of the push housing are fixedly connected to the outer housing. A square block is slidably connected to the inner side of the outer housing. The square block slides on the inner side of the outer housing to squeeze and contract the protrusions, which facilitates the disassembly of the component.

[0014] This invention provides a sheet metal bending machine for processing stainless steel sheets. It has the following beneficial effects: I. This stainless steel sheet bending machine, through its bending device design, places the sheet metal on the bending table. A hydraulic column drives a buffer mechanism to compress an auxiliary rod, causing the auxiliary rod to push the bending block towards the bearing mechanism, thus achieving the bending effect. A pushing mechanism then pushes the bent sheet metal to remove the material. This reduces manual disassembly, lowers the safety hazards of manual operation, improves equipment efficiency, prevents severe wear of components after prolonged operation, avoids affecting component performance, prevents damage to critical components from manual material handling, prevents collision deformation, scratches, or contamination, avoids abnormal load caused by manual intervention, eliminates the "high-risk operation risk" of manual material handling, avoids the risk of "die clamping," and is located away from high-pressure operating areas, reducing the risk of "sheet metal falling" and "scratches." Risk control and stable material handling process shorten the operation cycle, reduce equipment downtime, avoid interference from manual material handling to subsequent processing, and prevent positioning deviation caused by manual touch. The buffer mechanism plays a shock absorption and cushioning role, thereby reducing the extrusion force, preventing excessive extrusion of parts, preventing excessive damage to parts, buffering instantaneous impact, protecting the core components of the equipment, reducing the load on the transmission system, optimizing the bending process, improving workpiece quality, avoiding "overpressure damage" to the workpiece, reducing "springback error", reducing the risk of equipment malfunction, ensuring operational safety, preventing "overload protection false triggering", reducing the risk of "parts falling off", and thus extending the service life of the equipment. Secondly, the bearing mechanism plays a buffering role during the downward compression process, thereby reducing the impact of external pressure on the parts, dispersing the extrusion stress, protecting the core structure of the bearing platform, and preventing "bottom crushing" or "local deformation" of the workpiece on the bending table. The device reduces deformation and cracking of the main body, minimizes bending springback and angular deviation, improves equipment stability, reduces safety hazards, and suppresses vibration and noise. This reduces mechanical wear and rigid collisions between components, providing a certain degree of protection. After prolonged operation, debris easily accumulates on the equipment surface. A pneumatic device flushes one side of the protective platform to clean impurities from the component surface, reducing debris buildup and preventing damage to the sheet metal during compression, thus ensuring the integrity of the sheet metal. It also removes impurities from the worktable, ensures bending accuracy, avoids the risk of workpiece crushing, protects equipment components, extends service life, reduces mold wear, reduces mechanism jamming, improves the operating environment, reduces safety hazards, prevents injury from flying debris, and reduces hazards caused by oil accumulation.

[0015] II. This stainless steel plate bending machine, through its buffer mechanism design, pushes a sliding block to slide inside the buffer housing, compressing and contracting the first spring. This serves as a shock absorber, reducing the compressive force, preventing excessive compression of components, preventing excessive damage to components, buffering instantaneous impacts, protecting core components of the equipment, reducing the load on the transmission system, optimizing the bending process, improving workpiece quality, avoiding "overpressure damage" to the workpiece, reducing "springback error," lowering the risk of equipment malfunctions, ensuring operational safety, preventing "overload protection false triggering," reducing the risk of "component detachment," and thus extending the service life of the equipment. During the sliding process, the sliding block drives the outer block to slide on the inner wall of the slide groove, thereby limiting the sliding range of the components and preventing excessive sliding, providing a certain degree of protection for the components. The buffer pad increases the wear resistance of the components, thereby reducing wear between components and extending their service life.

[0016] Third, the stainless steel plate bending machine, through its load-bearing mechanism design, ensures that when the bending block presses against the protective mechanism, the protective mechanism drives the load-bearing shell to press against the damping rod, thereby playing a role in shock absorption and buffering. This reduces the impact of external pressure on the components, disperses the compressive stress, protects the core structure of the load-bearing platform, and prevents the workpiece from being "crushed at the bottom" or "deformed locally," thus preventing deformation and cracking. The protective mechanism also reduces "bending springback" and "angle deviation," improves equipment stability, reduces safety hazards, and suppresses "vibration and noise," thereby reducing mechanical wear between components and reducing rigid collisions between components, thus providing a certain degree of protection for the components.

[0017] IV. This stainless steel sheet bending machine features a pneumatic design. The grating and grating cover prevent external impurities from entering, avoiding their accumulation on the fan surface and preventing excessive buildup that could affect fan rotation and component operating efficiency. The fan generates airflow to flush the bending table surface, cleaning impurities and reducing debris buildup. This prevents damage to the sheet metal during pressing, ensuring sheet integrity, removing impurities from the worktable, guaranteeing bending accuracy, avoiding workpiece damage, protecting equipment components, extending service life, reducing die wear, minimizing mechanism jamming, improving the operating environment, reducing safety hazards, preventing debris splashing injuries, and reducing oil buildup hazards. An electric push rod controls the lifting of the connecting frame, adjusting the component angle to meet different operational needs and providing space for sheet metal movement.

[0018] V. This stainless steel plate bending machine, through its rotating mechanism design, uses a fan to generate airflow. This airflow acts on the fan surface, causing the fan to rotate the connecting shaft. The connecting shaft then controls a scraper to rub against the inner wall of the grille, thereby cleaning impurities from the component surface. This promotes the outward discharge of impurities, preventing excessive accumulation and blockage of surface pores, thus avoiding impurity buildup, restoring airflow efficiency, ensuring the fan's exhaust efficiency, removing physical blockages from the grille gaps, preventing airflow attenuation, removing sticky contaminants from the grille surface, preventing airflow turbulence, protecting core components, and extending equipment lifespan. This reduces pollutants entering the fan, lowers internal dirt accumulation and corrosion, ensures safety and protection, avoids risks to personnel and equipment, prevents grille deformation and breakage, prevents accidental contact, prevents accelerated grille corrosion, and avoids structural failure. The silicone blocks are made of silicone material to prevent bidirectional damage between components, prevent component scratches, deformation or coating peeling, reduce wear, extend service life, adapt to grille gaps, penetrate deep into gaps, remove stubborn blockages, enhance frictional fit, avoid cleaning dead corners, improve the adaptability and operational stability of the friction process, reduce vibration and noise, improve operational safety and environmental friendliness, and avoid secondary damage from metal debris.

Detailed Implementation

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] First embodiment, such as Figures 1 to 5 As shown, the present invention provides a technical solution: a sheet metal bending machine for processing stainless steel sheets, including a bending device 1, and a pushing mechanism 3 is fixedly connected inside the bending device 1; The bending device 1 includes a bending base 11, a support frame 12 fixedly connected to the top of the bending base 11, a bending frame body 13 fixedly connected to the edge of the top of the support frame 12, a bending table 18 fixedly connected to the middle of the top of the support frame 12, a support mechanism 19 fixedly connected to the bottom of the groove inside the bending table 18, a push mechanism 3 fixedly connected to the bottom of the middle of the top of the bending table 18, a pneumatic device 2 fixedly connected to one side of the top of the bending table 18, a hydraulic column 14 fixedly connected to the middle of the top of the bending frame body 13, a buffer mechanism 15 fixedly connected to the bottom of the hydraulic column 14, an auxiliary rod 16 slidably connected to the side of the top of the bending frame body 13 near the hydraulic column 14, and a bending block 17 fixedly connected to the outside of the auxiliary rod 16 near the bending table 18.The sheet metal is placed on the bending table 18. The hydraulic column 14 drives the buffer mechanism 15 to press the auxiliary rod 16, causing the auxiliary rod 16 to push the bending block 17 towards the bearing mechanism 19, thus bending the sheet metal. The pushing mechanism 3 then pushes the bent sheet metal to remove the material. This reduces manual disassembly, lowers safety hazards associated with manual operation, improves equipment efficiency, prevents severe wear on components after prolonged operation, avoids affecting component performance, prevents damage to critical components during manual material handling, prevents collision deformation, scratches, or contamination, avoids abnormal load caused by manual intervention, eliminates the "high-risk operation risk" of manual material handling, avoids the risk of "mold clamping," and keeps the equipment away from high-pressure operating areas, reducing the risk of "sheet metal falling" and "scratches." To mitigate risks, stabilize the material handling process, shorten the work cycle, reduce equipment downtime, avoid interference from manual material handling with subsequent processing, and prevent positioning deviations caused by manual touch, the buffer mechanism 15 acts as a shock absorber, thereby reducing the extrusion force, preventing excessive extrusion of components, preventing excessive damage to components, buffering instantaneous impacts, protecting core equipment components, reducing the load on the transmission system, optimizing the bending process, improving workpiece quality, avoiding "overpressure damage" to workpieces, reducing "springback error," reducing equipment malfunction risks, ensuring operational safety, preventing "overload protection false triggering," reducing the risk of "component detachment," and thus extending the service life of the equipment. Secondly, the bearing mechanism 19 acts as a buffer during the downward compression process, thereby reducing the impact of external pressure on components, dispersing extrusion stress, protecting the core structure of the bearing platform, and preventing the bending table 18 from "bottom crushing" or "localized" damage to the workpiece. The deformation and cracking of the main body reduces bending springback and angular deviation, improves equipment stability, reduces safety hazards, and suppresses vibration and noise. This reduces mechanical wear between components and rigid collisions, thus providing a certain degree of protection. After prolonged operation, debris easily accumulates on the surface of the equipment. The pneumatic device 2 flushes one side of the bending table 18 to clean impurities from the component surface, reducing debris retention and preventing damage to the sheet metal during extrusion, thereby ensuring the integrity of the sheet metal. It also removes impurities from the worktable, ensures bending accuracy, avoids the risk of workpiece damage, protects equipment components, extends service life, reduces mold wear, reduces mechanism jamming, improves the operating environment, reduces safety hazards, prevents injury from flying debris, and reduces hazards caused by oil accumulation.

[0023] The buffer mechanism 15 includes a buffer housing 151, a sliding block 152 slidably connected to the inner side of the buffer housing 151, a groove 154 formed on the inner side of the buffer housing 151, an outer block 153 fixedly connected to the outer side of the sliding block 152, the outer side of the outer block 153 slidably connected to the inner wall of the groove 154, a buffer pad 156 fixedly connected to the outer side of the buffer housing 151 near the bending block 17, a first spring 155 fixedly connected to the bottom of the inner wall of the buffer housing 151, and the outer side of the first spring 155 fixedly connected to the outer side of the sliding block 152. During the compression process of the hydraulic column 14, the sliding block 152 is pushed to slide inside the buffer housing 151 to compress and contract the first spring 155, thereby playing a role in shock absorption and buffering. This reduces the compression force, avoids excessive compression of components, prevents excessive damage to components, buffers instantaneous impact, protects the core components of the equipment, reduces the load on the transmission system, optimizes the bending process, improves the quality of the workpiece, avoids "overpressure damage" to the workpiece, reduces "springback error", reduces the risk of equipment malfunction, ensures operational safety, prevents "overload protection false triggering", reduces the risk of "component detachment", and thus extends the service life of the equipment. During the sliding process of the sliding block 152, it drives the outer block 153 to slide on the inner wall of the slide groove 154, thereby limiting the sliding range of the component and avoiding excessive sliding of the component, which provides a certain protective effect on the component. The buffer pad 156 increases the wear resistance of the component, thereby reducing wear between components and extending the service life of the component.

[0024] The bearing mechanism 19 includes a bearing housing 191, with a damping rod 192 slidably connected inside the bearing housing 191. A cylindrical groove 194 is formed in the middle of the bearing housing 191, and a protective mechanism 193 is fixedly connected to the inner wall of the cylindrical groove 194. When the bending block 17 presses against the protective mechanism 193, the protective mechanism 193 drives the bearing housing 191 to press against the damping rod 192, thereby playing a role in shock absorption and buffering. This reduces the impact of external pressure on the components, disperses the compressive stress, protects the core structure of the bearing platform, and prevents the bending platform 18 from "bottom crushing" or "local deformation" of the workpiece, thus preventing deformation and cracking. The protective mechanism 193 reduces "bending springback" and "angle deviation", improves equipment stability, reduces safety hazards, and suppresses "vibration and noise", thereby reducing mechanical wear between components and reducing rigid collisions between components, thus providing a certain degree of protection for the components.

[0025] The protective mechanism 193 includes a second spring 1931. One side of the second spring 1931 is fixedly connected to the bottom of the inner wall of the cylindrical groove 194. A connecting rod 1932 is fixedly connected to the other side of the second spring 1931. The outer side of the connecting rod 1932 is slidably connected to the inner side of the cylindrical groove 194. A protective plate 1933 is fixedly connected to the outer side of the connecting rod 1932 away from the second spring 1931. The protective plate 1933 drives the connecting rod 1932 to compress the second spring 1931 inside the cylindrical groove 194, thereby playing a role in shock absorption and buffering. This reduces the impact of external pressure on the components, disperses the compressive stress, protects the core structure of the bearing platform, prevents the bending platform 18 from "bottom crushing" or "local deformation" of the workpiece, avoids body deformation and cracking, reduces "bending springback" and "angle deviation", improves equipment stability, reduces safety hazards, and suppresses "vibration and noise". This reduces mechanical wear between components and reduces rigid collisions between components, thus providing a certain degree of protection for the components.

[0026] The second embodiment is based on the first embodiment; please refer to [link / reference]. Figures 6 to 7 As shown, the pneumatic device 2 includes a pneumatic frame 21, a fan 23 is fixedly connected to the inner side of the pneumatic frame 21, a grid plate 22 is fixedly connected to one side of the outer side of the pneumatic frame 21, a grid cover 24 is fixedly connected to the outer side of the pneumatic frame 21 away from the grid plate 22, and a rotating mechanism 27 is fixedly connected to the inner wall of the grid cover 24. The grating plate 22 and grating cover 24 serve to block external impurities from entering, preventing impurities from settling on the surface of the fan 23, preventing excessive accumulation of impurities, avoiding affecting the rotation of the fan 23, and preventing impact on the operating efficiency of the components. Secondly, the fan 23 generates airflow, which washes the surface of the bending table 18, thereby cleaning impurities from the component surface, reducing debris retention, and preventing debris from damaging the sheet metal during the extrusion process, thus ensuring the integrity of the sheet metal, removing impurities from the worktable, ensuring bending accuracy, avoiding the risk of "workpiece crushing", protecting equipment components, extending service life, reducing "die wear", reducing "mechanical jamming" problems, improving the operating environment, reducing safety hazards, preventing "scratching debris" injuries, and reducing the hazards caused by "oil accumulation".

[0027] The pneumatic frame 21 has connecting frames 25 fixedly connected to both sides of the side closest to the grating plate 22. An electric push rod 26 is fixedly connected to the inner side of the connecting frame 25. The connecting frame 25 is raised by controlling the electric push rod 26, thereby adjusting the angle of the components to meet different subsequent operation requirements. By adjusting the angle of the components, the movement of the plate is avoided, thus providing space for the plate to move.

[0028] The rotating mechanism 27 includes a fixed frame 271. The outer side of the fixed frame 271 is fixedly connected to the inner wall of the grille cover 24. A connecting shaft 272 is rotatably connected to the inner side of the fixed frame 271. A fan 273 is fixedly connected to one side of the connecting shaft 272. A scraper 274 is fixedly connected to the outer side of the connecting shaft 272 away from the fan 273. A silicone block 275 is fixedly connected to the outer side of the scraper 274 near the grille cover 24. The fan 23 generates airflow, which acts on the surface of the fan 273. The fan 273 drives the connecting shaft 272 to rotate, causing the connecting shaft 272 to control the scraper 274 to rub against the inner wall of the grille cover 24. This cleans impurities from the surface of the components, promotes the outward discharge of impurities, prevents excessive accumulation of impurities, prevents blockage of the surface holes of the components, avoids affecting the airflow effect, restores the ventilation channel, ensures the "exhaust efficiency" of the fan, removes "physical blockages" from the grille gaps, prevents airflow attenuation, removes "sticky pollutants" from the grille surface, prevents airflow turbulence, protects the core components of the components, extends the service life of the equipment, and reduces pollutants. Entering the fan 23, it reduces internal dirt and corrosion, ensures safety protection, avoids risks to personnel and equipment, prevents grille deformation and breakage, prevents accidental contact, prevents accelerated grille corrosion, and avoids structural failure. The silicone block 275 is made of silicone material to avoid bidirectional damage between components, prevents component scratches, deformation or coating peeling, reduces its own wear, extends service life, adapts to grille gaps, penetrates deep into gaps, removes stubborn blockages, enhances frictional fit, avoids cleaning dead corners, improves the adaptability and operational stability of the friction process, reduces vibration and noise, improves operational safety and environmental friendliness, and avoids secondary damage from metal debris.

[0029] The third embodiment is based on embodiments one and two; please refer to [link / reference]. Figures 8 to 9As shown, the pushing mechanism 3 includes a slide rail 301, a pushing housing 302 is slidably connected to the top of the slide rail 301, a support block 303 is inserted into the inner side of the pushing housing 302, and a pushing plate 304 is inserted into the outer side of the support block 303 away from the pushing housing 302. By pushing the housing 302 to slide on the slide rail 301, the support block 303 drives the push plate 304 to push the bent sheet material, thereby removing the material. This reduces manual disassembly, lowers the safety hazards of manual operation, and improves the operating efficiency of the equipment. The support block 303 and the push plate 304 are connected by a plug-in joint for easy disassembly and installation. This avoids severe wear of components after long-term operation, prevents the impact on the operating effect of components, avoids damage to key components of the equipment caused by manual material handling, prevents collision deformation, scratches or contamination, avoids abnormal load caused by manual intervention, eliminates the "high-risk operation risk" of manual material handling, avoids the risk of "mold clamping", keeps away from high-pressure operating areas, reduces the risk of "sheet material falling" and "scratching", stabilizes the material handling process, shortens the operation cycle, reduces equipment downtime, avoids interference of manual material handling with subsequent processing, and avoids positioning deviation caused by manual touch.

[0030] A soft rubber block 305 is fixedly connected to the side of the push plate 304 away from the support block 303. A cutout 306 is formed on the side of the soft rubber block 305 away from the push plate 304. The soft rubber block 305 is made of soft rubber to increase the wear resistance and cushioning effect of the component surface, thereby reducing rigid collisions between components, reducing wear between components, extending the service life of the component, and reducing damage to the pushing component. Secondly, the cutout 306 enhances the deformation performance of the component, further improving the cushioning effect. Thirdly, the cutout adds surface texture to the component, providing a certain degree of protection and improving the pushing effect of the component.

[0031] The support block 303 has a groove 307 on its inner side. A third spring 308 is fixedly connected to the inner wall of the groove 307. A protrusion 309 is fixedly connected to one side of the third spring 308. The outer side of the protrusion 309 is slidably connected to the inner side of the groove 307. An outer housing 310 is fixedly connected to both sides of the outer side of the push housing 302. A square block 311 is slidably connected to the inner side of the outer housing 310. The support block 303 is provided with protrusions 309 on both sides of its outer side. The support block 303 is inserted into the inner side of the push housing 302. The protrusions 309 are compressed by the surface of the component, which compresses and contracts the third spring 308. The protrusions 309 mate with the outer housing 310, thereby fixing the component. The square block 311 slides inside the outer housing 310, compressing and contracting the protrusions 309, which facilitates the disassembly of the component.

[0032] In use, the sheet metal is placed on the bending table 18. The hydraulic column 14 drives the buffer mechanism 15 to press the auxiliary rod 16, causing the auxiliary rod 16 to push the bending block 17 towards the bearing mechanism 19, thus bending the sheet metal. The pushing mechanism 3 then pushes the bent sheet metal to remove the material. This reduces manual disassembly, lowers safety hazards associated with manual operation, improves equipment efficiency, prevents severe wear on components after prolonged operation, avoids affecting component performance, prevents damage to critical components during manual material handling, prevents collision deformation, scratches, or contamination, avoids abnormal load caused by manual intervention, eliminates the "high-risk operation risk" of manual material handling, avoids the risk of "mold clamping," and keeps the equipment away from high-pressure work areas to reduce "sheet metal falling" and "scratches." To mitigate risks, stabilize the material handling process, shorten the work cycle, reduce equipment downtime, avoid interference from manual material handling with subsequent processing, and prevent positioning deviations caused by manual touch, the buffer mechanism 15 acts as a shock absorber, thereby reducing the extrusion force, preventing excessive extrusion of components, preventing excessive damage to components, buffering instantaneous impacts, protecting core equipment components, reducing the load on the transmission system, optimizing the bending process, improving workpiece quality, avoiding "overpressure damage" to workpieces, reducing "springback error," reducing equipment malfunction risks, ensuring operational safety, preventing "overload protection false triggering," reducing the risk of "component detachment," and thus extending the service life of the equipment. Secondly, the bearing mechanism 19 acts as a buffer during the downward compression process, thereby reducing the impact of external pressure on components, dispersing extrusion stress, protecting the core structure of the bearing platform, and preventing the bending table 18 from "bottom crushing" or "localized" damage to the workpiece. The deformation and cracking of the main body reduces bending springback and angular deviation, improves equipment stability, reduces safety hazards, and suppresses vibration and noise. This reduces mechanical wear between components and rigid collisions, thus providing a certain degree of protection. After prolonged operation, debris easily accumulates on the surface of the equipment. The pneumatic device 2 flushes one side of the bending table 18 to clean impurities from the component surface, reducing debris retention and preventing damage to the sheet metal during extrusion, thereby ensuring the integrity of the sheet metal. It also removes impurities from the worktable, ensures bending accuracy, avoids the risk of workpiece damage, protects equipment components, extends service life, reduces mold wear, reduces mechanism jamming, improves the operating environment, reduces safety hazards, prevents injury from flying debris, and reduces hazards caused by oil accumulation.
