Description

Technical Field

[0001] This invention relates to the field of steel structure production technology, specifically to a steel plate straightening device for steel structure production and processing. Background Technology

[0002] Steel structures are mainly composed of steel beams, steel columns, and steel trusses made of shaped steel and steel plates. These components are typically connected by welds, bolts, or rivets. The flatness and quality of the steel plates directly affect the overall performance and stability of the steel structure. Therefore, during the production and processing of steel structures, precise straightening of the steel plates is necessary to meet the usage requirements.

[0003] With advancements in rolling and online heat treatment technologies, the strength and performance of steel plates produced by steel enterprises are continuously improving. Currently, existing equipment, when handling steel plates of varying thicknesses and heights, cannot adjust the degree of plastic deformation in segments in real time, resulting in low leveling quality and efficiency. Furthermore, some equipment can only perform roll forming on steel plates, offering poor extrusion and straightening effects on the rolled edges of the steel plates. Summary of the Invention

[0004] To achieve the above objectives, the present invention is implemented through the following technical solution: a steel plate straightening device for steel structure production and processing, comprising: a guiding assembly, which is used for smooth conveying of steel plates during straightening; a support rod is fixedly installed on the side of the bottom of the guiding assembly; two sets of support rods are provided; a reinforcing frame is fixedly installed between the adjacent surfaces of the two sets of support rods; and a base frame is fixedly installed at the bottom of each support rod. A roll forming assembly is used for straightening and flattening steel plates. The roll forming assembly has fixed frames on both sides of its top. A hydraulic cylinder is fixed on the top of the fixed frame. The hydraulic cylinder extends through the fixed frame to the top of the roll forming assembly. The roll forming assembly is mounted above the guide assembly via the hydraulic cylinder drive. A collection component is used to collect metal shavings scattered during the straightening process. This collection component is fixedly installed at the bottom of the guide component and positioned between the opposite faces of the support rods. During steel plate straightening, the worker first adjusts the distance between the straightening component and the guide component according to the plate thickness, and then places the steel plate on the guide component. As the guide component rotates, it transports the steel plate below the straightening component. The worker then activates the straightening component, moving it above the guide component. The moving straightening component rolls the steel plate above the guide component, applying repeated bending forces through alternating flattening rollers, causing elastoplastic deformation and eliminating uneven internal stress and surface roughness. As the straightening component moves, the steel plate slides on the guide component to the other side, completing the straightening process. Metal shavings scattered on the steel plate during straightening fall into the collection component for subsequent recycling and processing.

[0005] Preferably, the roll forming assembly includes a guide limiting frame, inside which a lifting frame is movably installed. Two lifting frames are provided, each with a guide groove inside. A crossbeam is positioned between the opposing faces of the lifting frames. An inner plate is fixedly installed inside the crossbeam, and a sliding rod is fixedly installed on the outer surface of the inner plate. A pressure roller assembly is slidably installed on the outer surface of the crossbeam. The operator adjusts the distance between the lifting frame and the rotating roller according to the steel plate thickness using a hydraulic cylinder. Then, the operator conveys the steel plate between the rotating roller and the pressure roller assembly using a guide roller. The operator starts the motor, which drives the pressure roller assembly to run, causing the sliding rod to move the pressure roller assembly within the guide groove. Roll forming forces the bent steel plate between the rotating roller and the pressure roller assembly to bend in the opposite direction to its original deformation, causing the internal fibers of the steel plate to undergo tensile and compressive plastic deformation. The pressure roller assembly is designed as an adjustable structure, allowing adjustment according to the steel plate thickness during straightening. This enables segmented roll forming for variations in steel plate thickness, thereby improving the accuracy of roll forming.

[0006] Preferably, the lifting frame is fixedly installed at the bottom of the hydraulic cylinder, the lifting frame is movably installed inside the guide limit frame via the hydraulic cylinder, the slide rod extends through the guide groove to the outside of the lifting frame, and the slide rod is slidably installed inside the guide groove.

[0007] Preferably, the pressure plate roller assembly includes two extension plates. Each extension plate has a sleeve block fixedly installed on its top and a mounting frame fixedly installed on its bottom. Each mounting frame has a rotating groove inside, and there are five sets of rotating grooves. Each of the five sets of rotating grooves has a flattening roller rotatably installed inside. A connecting pad is fixedly installed on the outer surface of the mounting frame, and a pressure plate arc block is fixedly installed at the bottom of the connecting pad.

[0008] Preferably, the sleeve block is slidably mounted on the outer surface of the crossbeam, the connecting pad is fixedly mounted between adjacent surfaces of the flattening roller, and both the flattening roller and the pressure plate arc block are frictionally adapted to the surface of the steel plate. When the crossbeam and the slide rod drive the extension plate to move, the flattening roller and the rotating roller cooperate to perform roll pressing and straightening on the steel plate. The pressure plate arc blocks set on both sides of the mounting frame are positioned between the two flattening rollers, increasing the contact area with the side of the steel plate during roll pressing, thereby improving the effect of squeezing and straightening the rolled edge of the steel plate.

[0009] Preferably, the guiding assembly includes two beams, with a rotating roller rotatably mounted between the opposing surfaces of the two beams. Connecting plates are fixedly mounted on both sides of the outer surface of each beam, and two sets of connecting plates are provided. Side-mounted arc plates are fixedly mounted on the outer surfaces of both sets of connecting plates, and guide rollers are rotatably mounted between the opposing surfaces of the side-mounted arc plates. The operator places the steel plate above the guide rollers and then pushes the steel plate to rotate the guide rollers. The steel plate is conveyed above the rotating rollers through the coordinated operation of multiple sets of guide rollers. The guide rollers are arranged in an arc shape on both sides of the beams according to the shape of the side-mounted arc plates. For coiled steel plates, the curved surface design of the arc-shaped guide rollers matches the curvature of the coil, facilitating stable placement and gradual unrolling of the coil. The arc structure disperses the weight of the steel plate, preventing it from directly pressing against the inlet end of the straightening equipment under gravity. This buffered feeding method replaces the traditional flat feeding rack, reducing hard friction between the coil and the rack, and preventing deformation or scratches on the edges of the coil due to uneven stress.

[0010] Preferably, the beam frame is fixedly installed on the top of the support rod, the beam frame is fixedly installed on the bottom of the guide limit frame, and the beam frame is fixedly installed on both sides of the outer surface of the collecting assembly.

[0011] Preferably, the collecting component includes mounting plates, and two mounting plates are provided. Each mounting plate has a chip guide groove on its surface. Swinging components are fixedly mounted on both sides of the outer surface of the mounting plates, and an arc-shaped chip receiving plate is movably mounted between the opposing surfaces of the swinging components. During steel plate straightening, impurities such as metal shavings, oxide scale, and iron filings are generated. If these metal shavings remain on the surface of the steel plate or on the working parts of the straightening machine, they may cause the steel plate surface to be crushed or scratched, affecting the appearance and surface quality of the finished product. Furthermore, the metal shavings can cause uneven force on the straightening machine rollers, leading to steel plate misalignment or jamming during straightening, reducing straightening accuracy, and even causing secondary deformation. Therefore, when the roller pressing assembly and the conveying assembly work together to straighten the steel plate, the roller pressing compresses the metal chips attached to the steel plate and scatters them into the arc-shaped chip collecting plate. The inside of the arc-shaped chip collecting plate is made of magnetic material, and the bottom of the arc-shaped chip collecting plate is set in an arc shape to facilitate the discharge of scattered metal chips to both sides. The chip collecting can remove these impurities in time, ensuring that the contact surface between the steel plate and the equipment is smooth, and ensuring the flatness and surface integrity of the straightened steel plate. At the same time, the recovered metal chips can be remelted and processed to achieve resource recycling and reduce production costs.

[0012] Preferably, the mounting plate is disposed on the side of the outer surface of the beam frame, and the mounting plate is fixedly installed between adjacent surfaces of the beam frame. The swinging member is fixedly installed at the bottom of the beam frame, and the arc-shaped chip receiving plate is supported between opposite surfaces of the mounting plate by the swinging member.

[0013] Preferably, the swinging component includes a positioning plate, an expansion plate fixedly installed on the outer surface of the positioning plate, a support block fixedly installed on the outer surface of the expansion plate, the support block fixedly installed at the bottom of the beam frame, a connecting block fixedly installed at the middle of the outer surface of the support block, a spring band fixedly installed on the outer surface of the connecting block, and the spring band fixedly installed on the outer surface of the arc-shaped chip collecting plate. During steel plate straightening, the location and scattering range of metal chips are often not fixed. When the metal chips are rolled and scattered, they are adsorbed into the arc-shaped chip collecting plate made of magnetic material. At this time, the arc-shaped chip collecting plate experiences uneven force due to the accumulation of metal chips on both sides. The arc-shaped chip collecting plate then swings under the rotating roller. The high efficiency of swinging collection reduces chip accumulation, extends the continuous operating time of the equipment, reduces the frequency of downtime for cleaning, and indirectly improves production efficiency. Simultaneously, it avoids blind spots in metal chip collection, preventing chip residue in corners and gaps. The elastic band is made of elastic material. When the elastic band swings, it will stretch or contract due to the force. It absorbs and releases energy through elastic deformation, which plays a buffering role. When the arc-shaped chip plate swings, the elasticity of the elastic band can offset part of the impact force during the swing process, making the swing more stable and avoiding damage to the arc-shaped chip plate from collision with the beam frame.

[0014] This invention provides a steel plate straightening device for steel structure production and processing. It has the following beneficial effects: I. The steel plate straightening equipment used in this steel structure production process involves operators adjusting the distance between the lifting frame and the rotating rollers using hydraulic cylinders based on the steel plate thickness. The steel plate is then conveyed between the rotating rollers and the pressure roller assembly via guide rollers. The motor is then activated, driving the pressure roller assembly to slide within the guide groove. The rolling pressure forces the bent steel plate between the rotating rollers and the pressure roller assembly to bend in the opposite direction to its original deformation, causing tensile and compressive plastic deformation of the steel plate's internal fibers. The pressure roller assembly is adjustable, allowing for segmented rolling pressure to address variations in steel plate thickness, thereby improving the accuracy of the rolling straightening process.

[0015] 2. The steel plate straightening equipment for steel structure production and processing, when the extension plate is moved by the cross frame and slide bar, the flattening roller and the rotating roller cooperate to perform roll pressing and straightening of the steel plate. The pressure plate arc blocks set on both sides of the mounting frame are set between the two flattening rollers, which increases the contact area with the side of the steel plate during roll pressing, so as to improve the effect of squeezing and straightening the rolled edge of the steel plate.

[0016] III. The steel plate straightening equipment used in the steel structure production process involves workers placing the steel plate above the guide rollers, then pushing the plate to rotate the guide rollers. Multiple sets of guide rollers work together to transport the steel plate to the top of the rotating rollers. The guide rollers are arranged in an arc shape on both sides of the beam frame according to the shape of the side-mounted curved plates. For rolled steel plates, the curved surface design of the guide rollers matches the curvature of the rolled plate, facilitating stable placement and gradual unrolling. The arc structure distributes the weight of the steel plate, preventing it from directly pressing against the inlet of the straightening equipment under gravity. Buffer-type feeding replaces the traditional flat feeding rack, reducing hard friction between the rolled plate and the frame, and preventing deformation or scratches on the edges of the rolled plate due to uneven stress.

[0017] IV. The steel plate straightening equipment used in the production and processing of this steel structure uses a combination of roller pressing components and a guide component to straighten the steel plate. The roller pressing compresses the metal chips attached to the steel plate and scatters them into the arc-shaped chip collecting plate. The interior of the arc-shaped chip collecting plate is made of magnetic material, and the bottom of the arc-shaped chip collecting plate is set in an arc shape to facilitate the discharge of scattered metal chips to both sides. The chip collecting can remove these impurities in a timely manner, ensuring a smooth contact surface between the steel plate and the equipment, and guaranteeing the flatness and surface integrity of the straightened steel plate. At the same time, the recovered metal chips can be remelted and processed to achieve resource recycling and reduce production costs.

[0018] V. The steel plate straightening equipment used in the production and processing of this steel structure utilizes the high efficiency of oscillating collection to reduce debris accumulation, extend continuous operation time, decrease downtime for cleaning, and indirectly improve production efficiency. It also avoids blind spots in metal shavings collection, preventing debris residue in corners and crevices. The elastic band is made of elastic material; during oscillation, it stretches or contracts under stress, absorbing and releasing energy through elastic deformation, thus providing a buffer. When the curved chip receiving plate oscillates, the elasticity of the band can offset some of the impact force during the oscillation, making the oscillation smoother and preventing damage from collisions between the curved chip receiving plate and the beam frame.

[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 13 As shown, the present invention provides a technical solution: a steel plate straightening device for steel structure production and processing, comprising: a guide assembly 4, which is used for smooth conveying of steel plates during straightening; a support rod 6 is fixedly installed on the side of the bottom of the guide assembly 4; two sets of support rods 6 are provided; a reinforcing frame 7 is fixedly installed between the adjacent surfaces of the two sets of support rods 6; and a base frame 1 is fixedly installed at the bottom of each support rod 6. The guiding assembly 4 includes two beam frames 41. A rotating roller 44 is rotatably mounted between the opposing surfaces of the two beam frames 41. Connecting plates 45 are fixedly mounted on both sides of the outer surface of each beam frame 41. Two sets of connecting plates 45 are provided, and side-mounted arc plates 42 are fixedly mounted on the outer surfaces of both sets of connecting plates 45. Guide rollers 43 are rotatably mounted between the opposing surfaces of the side-mounted arc plates 42. The operator places a steel plate above the guide rollers 43 and then pushes the steel plate to rotate the guide rollers 43. The steel plate is conveyed above the rotating rollers 44 through the coordinated action of multiple sets of guide rollers 43. Guide rollers 43 are arranged in an arc shape on both sides of beam frame 41 according to the shape of side connecting arc plate 42. For rolled steel plates, the curved surface design of the arc-shaped guide rollers 43 can match the curvature of the rolled plate, which facilitates the smooth placement and gradual unfolding of the rolled plate. The arc structure can distribute the weight of the steel plate and prevent the steel plate from being directly pressed against the inlet end of the straightening equipment under the action of gravity. The buffer feeding replaces the traditional flat feeding rack, reduces the hard friction between the rolled plate and the frame, and prevents the edge of the rolled plate from being deformed or scratched due to uneven force.

[0023] The beam frame 41 is fixedly installed on the top of the support rod 6, the beam frame 41 is fixedly installed on the bottom of the guide limit frame 81, and the beam frame 41 is fixedly installed on both sides of the outer surface of the collecting assembly 5.

[0024] Roller pressing assembly 8 is used for straightening and flattening steel plates. Fixing frames 2 are fixedly installed on both sides of the top of the roller pressing assembly 8. A hydraulic cylinder 3 is fixedly installed on the top of the fixing frame 2. The hydraulic cylinder 3 extends through the fixing frame 2 to the top of the roller pressing assembly 8. The roller pressing assembly 8 is installed above the guide assembly 4 through the hydraulic cylinder 3. A collection component 5 is used to collect metal shavings scattered during the straightening rolling process. The collection component 5 is fixedly installed at the bottom of the guide component 4 and positioned between the opposite faces of the support rods 6. During steel plate straightening, the worker first adjusts the distance between the rolling component 8 and the guide component 4 according to the steel plate thickness, and then places the steel plate on the guide component 4. As the guide component 4 rotates, it transports the steel plate below the rolling component 8. The worker then activates the rolling component 8, moving it above the guide component 4. The moving rolling component 8 rolls the steel plate above the guide component 4, applying repeated bending force through alternating flattening rollers 875, causing elasto-plastic deformation and eliminating uneven internal stress and surface roughness. As the rolling component 8 moves, the steel plate slides on the guide component 4 to the other side, completing the straightening work. Metal shavings scattered on the steel plate during the straightening process fall into the collection component 5 for subsequent recycling and processing.

[0025] The second embodiment is based on the first embodiment; please refer to [link / reference]. Figures 6 to 8As shown, the collecting component 5 includes two mounting plates 51. Each mounting plate 51 has a chip guide groove 53 on its surface. Swinging members 54 are fixedly mounted on both sides of the outer surface of each mounting plate 51. An arc-shaped chip receiving plate 52 is movably mounted between the opposing surfaces of the swinging members 54. During steel plate straightening, impurities such as metal shavings, oxide scale, and iron filings are generated. If these metal shavings remain on the surface of the steel plate or on the working parts of the straightening machine, they may cause the steel plate surface to be crushed or scratched, affecting the appearance and surface quality of the finished product. Furthermore, the metal shavings can cause uneven force on the straightening machine rollers, leading to steel plate displacement or jamming during straightening, reducing straightening accuracy, and even causing secondary deformation. Therefore, when the roller pressing assembly 8 and the guiding assembly 4 work together to straighten the steel plate, the roller pressing causes the metal chips attached to the steel plate to be squeezed and scattered into the arc-shaped chip receiving plate 52. The interior of the arc-shaped chip receiving plate 52 is made of magnetic material, and the bottom of the arc-shaped chip receiving plate 52 is set in an arc shape to facilitate the scattered metal chips to be discharged to both sides. The chip collection can remove these impurities in time, ensuring that the contact surface between the steel plate and the equipment is smooth, ensuring the flatness and surface integrity of the straightened steel plate. At the same time, the recovered metal chips can be remelted and processed to realize resource recycling and reduce production costs.

[0026] The mounting plate 51 is disposed on the side of the outer surface of the beam frame 41, and the mounting plate 51 is fixedly installed between adjacent surfaces of the beam frame 41. The swing member 54 is fixedly installed at the bottom of the beam frame 41, and the arc-shaped chip receiving plate 52 is supported between opposite surfaces of the mounting plate 51 by the swing member 54.

[0027] The swinging component 54 includes a positioning plate 542, an expansion plate 541 is fixedly installed on the outer surface of the positioning plate 542, a support block 543 is fixedly installed on the outer surface of the expansion plate 541, the support block 543 is fixedly installed at the bottom of the beam frame 41, a connecting block 545 is fixedly installed at the middle of the outer surface of the support block 543, a spring band 544 is fixedly installed on the outer surface of the connecting block 545, and the spring band 544 is fixedly installed on the outer surface of the arc-shaped chip receiving plate 52. During steel plate straightening, the location and scattering range of metal chips are often unpredictable. When the metal chips are rolled and scattered, they are attracted to the magnetically-coated arc-shaped chip-collecting plate 52. At this time, the accumulation of metal chips on both sides of the arc-shaped chip-collecting plate 52 causes uneven force distribution. The arc-shaped chip-collecting plate 52 then swings below the rotating roller 44. The high efficiency of this swinging collection reduces chip accumulation, extends the continuous operating time of the equipment, reduces the frequency of downtime for cleaning, and indirectly improves production efficiency. It also avoids blind spots in chip collection, preventing chip residue in corners and gaps. The elastic band 544 is made of elastic material. When swinging, the elastic band 544 stretches or contracts under force, absorbing and releasing energy through elastic deformation, thus acting as a buffer. When the arc-shaped chip-collecting plate 52 swings, the elasticity of the elastic band 544 can offset some of the impact force during the swing, making the swing more stable and preventing damage from collisions between the arc-shaped chip-collecting plate 52 and the beam frame 41.

[0028] The third embodiment is based on embodiments one and two; please refer to [link / reference]. Figures 9 to 13 As shown, the roller pressing assembly 8 includes a guide limiting frame 81, and a lifting frame 82 is movably installed inside the guide limiting frame 81. There are two lifting frames 82, and each of the two lifting frames 82 has a guide groove 83 inside. A cross frame 84 is provided between the opposite faces of the lifting frames 82. An inner connecting plate 85 is fixedly installed inside the cross frame 84. A sliding rod 86 is fixedly installed on the outer surface of the inner connecting plate 85. A pressure roller group 87 is slidably installed on the outer surface of the cross frame 84. Workers adjust the distance between the lifting frame 82 and the rotating roller 44 using hydraulic cylinder 3 according to the steel plate thickness. Then, workers use guide roller 43 to transport the steel plate between the rotating roller 44 and the pressure roller assembly 87. The motor is then started, driving the pressure roller assembly 87 to slide within the guide groove 83, caused by sliding rod 86. The rolling pressure forces the bent steel plate between the rotating roller 44 and the pressure roller assembly 87 to bend in the opposite direction to its original deformation, causing plastic deformation of the internal fibers of the steel plate through stretching and compression. The pressure roller assembly 87 is designed as an adjustable structure, allowing adjustment according to the steel plate thickness during straightening. This segmented rolling pressure is then applied to variations in steel plate thickness, improving the accuracy of the rolling straightening process.

[0029] The lifting frame 82 is fixedly installed at the bottom of the hydraulic cylinder 3. The lifting frame 82 is movably installed inside the guide limit frame 81 through the hydraulic cylinder 3. The slide rod 86 extends through the guide groove 83 to the outside of the lifting frame 82. The slide rod 86 is slidably installed inside the guide groove 83.

[0030] The pressure plate roller assembly 87 includes two extension plates 872. Each extension plate 872 has a sleeve block 871 fixedly installed on its top. Each extension plate 872 has a mounting frame 873 fixedly installed on its bottom. Each mounting frame 873 has a rotating groove 877 inside. There are five sets of rotating grooves 877. Each set of rotating grooves 877 has a flattening roller 875 rotatably installed inside. A connecting pad 876 is fixedly installed on the outer surface of the mounting frame 873. A pressure plate arc block 874 is fixedly installed at the bottom of the connecting pad 876.

[0031] The sleeve block 871 is slidably mounted on the outer surface of the cross frame 84, and the connecting pad 876 is fixedly mounted between adjacent surfaces of the flattening roller 875. Both the flattening roller 875 and the pressure plate arc block 874 are frictionally adapted to the surface of the steel plate. When the cross frame 84 and the slide rod 86 drive the extension plate 872 to move, the flattening roller 875 cooperates with the rotating roller 44 to perform roll pressing and straightening on the steel plate. The pressure plate arc blocks 874 set on both sides of the mounting frame 873 are positioned between the two flattening rollers 875, increasing the contact area with the side of the steel plate during roll pressing, thereby improving the effect of squeezing and straightening the rolled edge of the steel plate.

[0032] During operation, when straightening steel plates, the factory workers first adjust the distance between the roller pressing assembly 8 and the guide assembly 4 according to the thickness of the steel plate, and then place the steel plate on the guide assembly 4. As the guide assembly 4 rotates, it transports the steel plate to below the roller pressing assembly 8. The workers then activate the roller pressing assembly 8, causing it to move above the guide assembly 4. At this time, the moving roller pressing assembly 8 rolls the steel plate above the guide assembly 4, applying repeated bending force through the alternating flattening rollers 875, causing it to undergo elasto-plastic deformation, thereby eliminating uneven internal stress and surface unevenness. As the roller pressing assembly 8 moves, the steel plate slides on the guide assembly 4 to the other side, thus completing the straightening work. Metal shavings scattered on the steel plate during roller straightening fall into the collection assembly 5 for subsequent recycling and processing.

[0033] Workers place the steel plate above the guide roller 43 and then push the steel plate to make it rotate the guide roller 43. The steel plate is conveyed to the top of the rotating roller 44 by the cooperation of multiple sets of guide rollers 43. The guide rollers 43 are arranged in an arc shape on both sides of the beam frame 41 according to the shape of the side arc plate 42. For coiled steel plates, the curved surface design of the arc-shaped guide rollers 43 can match the curvature of the coil, which facilitates the stable placement and gradual unfolding of the coil. The arc structure can distribute the weight of the steel plate and prevent the steel plate from pressing directly against the inlet end of the straightening equipment under the action of gravity. The buffered feeding replaces the traditional flat feeding rack, reducing the hard friction between the coil and the frame and preventing deformation or scratches on the edge of the coil due to uneven force.

[0034] Workers adjust the distance between the lifting frame 82 and the rotating roller 44 using hydraulic cylinder 3 according to the steel plate thickness. Then, workers use guide roller 43 to transport the steel plate between the rotating roller 44 and the pressure roller assembly 87. The motor is then started, driving the pressure roller assembly 87 to slide within the guide groove 83, caused by sliding rod 86. The rolling pressure forces the bent steel plate between the rotating roller 44 and the pressure roller assembly 87 to bend in the opposite direction to its original deformation, causing plastic deformation of the internal fibers of the steel plate through stretching and compression. The pressure roller assembly 87 is designed as an adjustable structure, allowing adjustment according to the steel plate thickness during straightening. This segmented rolling pressure is then applied to variations in steel plate thickness, improving the accuracy of the rolling straightening process.

[0035] When the cross frame 84 and the slide bar 86 move the extension plate 872, the flattening roller 875 and the rotating roller 44 cooperate to roll-press and straighten the steel plate. The pressure plate arc blocks 874 set on both sides of the mounting frame 873 are set between the two flattening rollers 875 to increase the contact area with the side of the steel plate during rolling, so as to improve the effect of squeezing and straightening the rolled edge of the steel plate.

[0036] During steel plate straightening, impurities such as metal shavings, oxide scale, and iron filings are generated. If these metal shavings remain on the surface of the steel plate or on the working parts of the straightening machine, they may cause the steel plate surface to be crushed or scratched, affecting the appearance and surface quality of the finished product. Furthermore, the metal shavings can cause uneven force on the straightening machine rollers, leading to steel plate misalignment or jamming during straightening, reducing straightening accuracy, and even causing secondary deformation. Therefore, when the roller pressing assembly 8 and the guiding assembly 4 work together to straighten the steel plate, the roller pressing compresses the metal shavings attached to the steel plate, causing them to scatter within the arc-shaped chip collecting plate 52. The interior of the arc-shaped chip collecting plate 52 is made of magnetic material, and the bottom of the arc-shaped chip collecting plate 52 is designed with an arc shape to facilitate the scattering of metal shavings to both sides. The chip collecting plate can promptly remove these impurities, ensuring a smooth contact surface between the steel plate and the equipment, guaranteeing the flatness and surface integrity of the straightened steel plate. Simultaneously, the recovered metal shavings can be remelted and processed, achieving resource recycling and reducing production costs.

[0037] During steel plate straightening, the location and scattering range of metal chips are often unpredictable. When the metal chips are rolled and scattered, they are attracted to the magnetically-coated arc-shaped chip-collecting plate 52. At this time, the accumulation of metal chips on both sides of the arc-shaped chip-collecting plate 52 causes uneven force distribution. The arc-shaped chip-collecting plate 52 then swings below the rotating roller 44. The high efficiency of this swinging collection reduces chip accumulation, extends the continuous operating time of the equipment, reduces the frequency of downtime for cleaning, and indirectly improves production efficiency. It also avoids blind spots in chip collection, preventing chip residue in corners and gaps. The elastic band 544 is made of elastic material. When swinging, the elastic band 544 stretches or contracts under force, absorbing and releasing energy through elastic deformation, thus acting as a buffer. When the arc-shaped chip-collecting plate 52 swings, the elasticity of the elastic band 544 can offset some of the impact force during the swing, making the swing more stable and preventing damage from collisions between the arc-shaped chip-collecting plate 52 and the beam frame 41.
