Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of steel structure production, in particular to a steel plate correcting equipment for steel structure production and processing. BACKGROUND

[0002] Steel structure is mainly composed of steel beams, steel columns and steel trusses and other components made of shaped steel and steel plates, and the components or parts are usually connected by welding, bolts or rivets. The flatness and quality of the steel plate directly affect the overall performance and stability of the steel structure, so in the production and processing of steel structure, the steel plate needs to be accurately corrected to meet the use requirements of the steel structure.

[0003] With the progress of rolling and online heat treatment technology, the strength performance of steel plates produced by steel enterprises is continuously improved. At present, the existing equipment cannot adjust the plastic deformation degree of the steel plate in sections in real time when adapting to different thickness and height steel plate operations, resulting in low leveling quality and efficiency. Some equipment can only roll the steel plate, and the effect of extrusion correction on the edge of the steel plate is poor. SUMMARY

[0004] To achieve the above purpose, the present application is realized by the following technical scheme: a steel plate correcting equipment for steel structure production and processing, comprising: a guide and conveying assembly for smooth conveying during steel plate correction, a support rod is fixedly installed at the edge of the bottom of the guide and conveying assembly, the support rod is provided with two groups, a reinforcing frame is fixedly installed between the adjacent surfaces of the two groups of support rods, and a bottom frame is fixedly installed at the bottom of the support rod;

[0005] a roller assembly for steel plate correction and flattening, a fixed frame is fixedly installed on both sides of the top of the roller assembly, a hydraulic cylinder is fixedly installed on the top of the fixed frame, the hydraulic cylinder extends through the fixed frame to the top of the roller assembly, and the roller assembly is driven and installed above the guide and conveying assembly by the hydraulic cylinder;

[0006] The collecting assembly is fixedly installed at the bottom of the guiding assembly and is arranged between the opposite surfaces of the supporting rod. When the factory corrects the steel plate, the workers first adjust the distance between the rolling assembly and the guiding assembly according to the thickness of the steel plate, and then place the steel plate on the guiding assembly. After the steel plate is conveyed to the lower side of the rolling assembly by rotating the guiding assembly, the workers start the rolling assembly to move the rolling assembly above the guiding assembly. At this time, the moving rolling assembly rolls the steel plate above the guiding assembly. The alternating arrangement of the flattening rollers applies repeated bending force to the steel plate to cause elastic-plastic deformation, so as to eliminate internal stress unevenness and surface unevenness. As the rolling assembly moves, the steel plate slides on the guiding assembly to the other side, thereby completing the correction work. The metal chips scattered on the steel plate during rolling correction fall into the collecting assembly for subsequent recycling and processing.

[0007] Preferably, the rolling assembly comprises a guide limiting frame, a lifting frame movably installed in the inside of the guide limiting frame, two lifting frames, a guide groove opened in the inside of each of the two lifting frames, a cross frame arranged between the opposite surfaces of the lifting frame, an inner connecting plate fixedly installed in the inside of the cross frame, a sliding rod fixedly installed on the outer surface of the inner connecting plate, and a pressure plate roller group slidingly installed on the outer surface of the cross frame. Workers adjust the distance between the lifting frame and the rotating roller through the hydraulic cylinder according to the thickness of the steel plate. Then, the workers convey the steel plate to the space between the rotating roller and the pressure plate roller group through the guide roller. The workers start the motor to drive the pressure plate roller group to run, so that the sliding rod drives the pressure plate roller group to slide in the guide groove. Rolling forces the steel plate between the rotating roller and the pressure plate roller group to bend in the direction opposite to the original deformation direction, causing the fibers in the steel plate to stretch and compress plastically. The pressure plate roller group is arranged in an adjustable structure, which can be adjusted according to the thickness of the steel plate during the correction of the steel plate, so as to segmentally roll the steel plate according to the thickness change of the steel plate, thereby improving the accuracy of the rolling correction.

[0008] Preferably, the lifting frame is fixedly installed at the bottom of the hydraulic cylinder, the lifting frame is movably installed in the inside of the guide limiting frame through the hydraulic cylinder, the sliding rod extends to the outside of the lifting frame through the guide groove, and the sliding rod is slidingly installed in the inside of the guide groove.

[0009] Preferably, the pressure plate roller group comprises an extension plate, two extension plates, a sleeve block fixedly installed on the top of each of the two extension plates, an installation frame fixedly installed on the bottom of each of the two extension plates, a rotating groove opened in the inside of each of the installation frames, five groups of rotating grooves, a flattening roller rotatably installed in the inside of each of the five groups of rotating grooves, a connecting pad fixedly installed on the outer surface of the installation frame, and a pressure plate arc block fixedly installed on the bottom of the connecting pad.

[0010] Preferably, the sleeve block is slidingly mounted on the outer surface of the cross frame, the connecting pad is fixedly mounted between the adjacent surfaces of the flattening roller, and the flattening roller and the pressing plate arc block are frictionally matched with the surface of the steel plate. When the cross frame and the sliding rod drive the extension plate to move, the flattening roller cooperates with the rotating roller to roll and correct the steel plate, and the pressing plate arc blocks arranged on both sides of the mounting frame are arranged between the two flattening rollers, which increases the contact area with the side edges of the steel plate during rolling, thereby improving the effect of extrusion correction of the curled edges of the steel plate.

[0011] Preferably, the guide assembly comprises two beam frames, rotating rollers are rotatably mounted between the opposite surfaces of the two beam frames, connecting plates are fixedly mounted on the outer surfaces of the two beam frames, the connecting plates are provided in two groups, side-connection arc plates are fixedly mounted on the outer surfaces of the two groups of connecting plates, and guide rollers are rotatably mounted between the opposite surfaces of the side-connection arc plates. The worker places the steel plate above the guide rollers, and then pushes the steel plate to drive the guide rollers to rotate, and the steel plate is conveyed above the rotating rollers through the cooperation between the multiple guide rollers. The guide rollers are arranged in an arc shape on the two sides of the beam frame according to the shape of the side-connection arc plates, and for the coiled steel plate, the curved surface design of the arc-shaped guide rollers can match the curvature of the coiled plate, so that the coiled plate can be conveniently and stably placed and gradually unfolded, and the arc-shaped structure can disperse the weight of the steel plate, so that the steel plate is not directly pressed to the inlet end of the correction equipment under the action of gravity, the buffer type feeding is replaced, the hard friction between the coiled plate and the frame body is reduced, and deformation or scratches of the edge of the coiled plate due to uneven stress are avoided.

[0012] Preferably, the beam frame is fixedly mounted on the top of the supporting rod, the beam frame is fixedly mounted on the bottom of the guide limiting frame, and the beam frame is fixedly mounted on the outer surfaces of the two sides of the collecting assembly.

[0013] Preferably, the collecting assembly comprises mounting plates, surfaces of the two mounting plates are provided with chip guiding grooves, outer surfaces of the mounting plates are fixedly provided with swing members on both sides, and the arc-shaped chip receiving plates are movably arranged between opposite surfaces of the swing members. During the correction of the steel plate, metal chips, scale, iron filings and other impurities are generated. If these metal chips remain on the surface of the steel plate or the working parts of the correction machine, the surface of the steel plate can be pressed and scratched, affecting the appearance and surface quality of the finished product, and the metal chips can cause uneven stress on the rollers of the correction machine, causing the steel plate to deviate and jam during the correction process, reducing the correction accuracy, and even causing secondary deformation. Therefore, when the rolling assembly and the guiding assembly cooperate to correct and process the steel plate, the rolling causes the metal chips attached to the steel plate to be extruded and scattered in the arc-shaped chip receiving plate. The interior of the arc-shaped chip receiving plate is made of magnetic material, and the bottom of the arc-shaped chip receiving plate is provided in an arc shape, so that the scattered metal chips are guided to both sides. The collected chips can remove these impurities in time, ensure the smooth contact between the steel plate and the equipment, ensure the flatness and surface integrity of the corrected steel plate, and the recycled metal chips can be reprocessed, realizing resource recycling and reducing production costs.

[0014] Preferably, the mounting plates are arranged at the side of the outer surface of the beam frame, and the mounting plates are fixedly arranged between adjacent surfaces of the beam frame. The swing members are fixedly arranged at the bottom of the beam frame, and the arc-shaped chip receiving plates are arranged between opposite surfaces of the mounting plates through the swing members.

[0015] Preferably, the swing member comprises a positioning plate, an outer expansion plate is fixedly arranged on the outer surface of the positioning plate, a support block is fixedly arranged on the outer surface of the outer expansion plate, the support block is fixedly arranged at the bottom of the beam frame, an adapter block is fixedly arranged at the middle of the outer surface of the support block, an elastic band is fixedly arranged on the outer surface of the adapter block, and the elastic band is fixedly arranged on the outer surface of the arc-shaped chip receiving plate. During the correction of the steel plate, the position and scattering range of the metal chips are often not fixed. When the metal chips are extruded and scattered, the metal chips are adsorbed in the arc-shaped chip receiving plate made of magnetic material. At this time, the arc-shaped chip receiving plate is unevenly stressed due to the accumulation of metal chips on both sides. At this time, the arc-shaped chip receiving plate will swing below the rotating roller. The efficiency of swinging collection can reduce the accumulation of chips, prolong the continuous operation time of the equipment, reduce the cleaning frequency during shutdown, indirectly improve the production efficiency, and avoid the existence of collection blind area during the collection of metal chips, so that the chips remaining in the corners and gaps are collected.

[0016] The present application provides a steel plate correction equipment for steel structure production and processing.

[0017] I. The steel plate straightening equipment for steel structure production and processing adjusts the distance between the lifting frame and the rotating roller through the hydraulic cylinder according to the thickness of the steel plate, and then the worker sends the steel plate to the rotating roller and the pressure plate roller group through the guide roller, and then the worker starts the motor to drive the pressure plate roller group to run, so that the sliding rod drives the pressure plate roller group to slide in the guide groove. The rolling forces the bent steel plate between the rotating roller and the pressure plate roller group to bend in the opposite direction of the original deformation direction, causing the internal fibers of the steel plate to stretch and compress. The pressure plate roller group is adjustable, so it can be adjusted according to the thickness of the steel plate during straightening, so that the steel plate can be rolled in sections according to the thickness, thereby improving the accuracy of the rolling straightening.

[0018] II. The steel plate straightening equipment for steel structure production and processing moves the extension plate through the cross frame and the sliding rod, and the flattening roller and the rotating roller cooperate to roll and straighten the steel plate. The pressure plate arc blocks on both sides of the mounting frame are arranged between the two flattening rollers to increase the contact area with the side edges of the steel plate during rolling, thereby improving the effect of extrusion straightening of the curled edges of the steel plate.

[0019] III. The steel plate straightening equipment for steel structure production and processing places the steel plate above the guide roller, and then the worker pushes the steel plate to drive the guide roller to rotate. The steel plate is transported to the top of the rotating roller through the cooperation of multiple guide rollers. The guide rollers are arranged in an arc shape on both sides of the beam frame according to the shape of the side arc plate. For coiled steel plates, the curved surface design of the arc-shaped guide rollers can match the curvature of the coiled plate, making it easy to place and gradually expand the coiled plate. The arc structure can disperse the weight of the steel plate, avoiding direct pressure on the inlet end of the straightening equipment under the action of gravity. The buffer type feeding replaces the traditional flat feeding frame, reduces the hard friction between the coiled plate and the frame, and avoids deformation or scratches on the edges of the coiled plate due to uneven stress.

[0020] IV. When the steel plate is straightened and processed by the rolling assembly and the guide assembly, the metal chips attached to the steel plate are extruded and scattered in 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 bent to facilitate the diversion of the scattered metal chips to both sides. The chip collector can remove these impurities in time, ensuring the smoothness of the contact surface between the steel plate and the equipment, and ensuring the flatness and surface integrity of the straightened steel plate. At the same time, the recovered metal chips can be reprocessed, realizing resource recycling and reducing production costs.

[0021] 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.

[0036] 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.

[0037] 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.

[0038] The guide assembly 4 comprises two beam frames 41, the opposite surfaces of the two beam frames 41 are rotatably connected with rotating rollers 44, the outer surfaces of the beam frames 41 are fixedly connected with two connecting plates 45, the outer surfaces of the two connecting plates 45 are fixedly connected with side arc plates 42, and the opposite surfaces of the side arc plates 42 are rotatably connected with guide rollers 43. The staff places the steel plate above the guide rollers 43, and then pushes the steel plate to drive the guide rollers 43 to rotate, and the steel plate is conveyed to above the rotating rollers 44 through the cooperation between the guide rollers 43. The guide rollers 43 are arranged in an arc shape on the two sides of the beam frame 41 according to the shape of the side arc plate 42. For the rolled steel plate, the curved surface design of the arc-shaped guide rollers 43 can match the curvature of the rolled plate, which facilitates the stable placement and gradual expansion of the rolled plate. The arc-shaped structure can disperse the weight of the steel plate, so that the steel plate is not directly pressed to the inlet end of the correction equipment under the action of gravity, and the traditional flat feeding frame is replaced, the hard friction between the rolled plate and the frame body is reduced, and the deformation or scratching of the edge of the rolled plate due to uneven stress is avoided.

[0039] The beam frame 41 is fixedly connected to the top of the supporting rod 6, fixedly connected to the bottom of the guide limiting frame 81, and fixedly connected to the outer surfaces of the collecting assembly 5.

[0040] The roller pressing assembly 8 is used for steel plate correction and flattening, two fixed frames 2 are fixedly connected to the top of the roller pressing assembly 8, a hydraulic cylinder 3 is fixedly connected to the top of the fixed frame 2, the hydraulic cylinder 3 extends through the fixed frame 2 to the top of the roller pressing assembly 8, and the roller pressing assembly 8 is driven by the hydraulic cylinder 3 and arranged above the guide assembly 4.

[0041] The collecting assembly 5 is used for collecting the metal scraps scattered during the correction and roller pressing, and is fixedly connected to the bottom of the guide assembly 4 and arranged between the opposite surfaces of the supporting rod 6. When the factory corrects the steel plate, the staff first adjusts the distance between the roller pressing assembly 8 and the guide assembly 4 according to the thickness of the steel plate, places the steel plate on the guide assembly 4, and then drives the roller pressing assembly 8 to move above the guide assembly 4 after the steel plate is conveyed to below the roller pressing assembly 8 by the rotation of the guide assembly 4. At this time, the moving roller pressing assembly 8 rolls the steel plate above the guide assembly 4, and the alternately arranged flattening rollers 875 apply repeated bending force to the steel plate to cause elastic-plastic deformation, so as to eliminate the internal stress unevenness and surface unevenness. With the movement of the roller pressing assembly 8, the steel plate slides on the guide assembly 4 to the other side, so as to complete the correction work. The metal scraps scattered on the steel plate during the roller pressing correction fall into the collecting assembly 5 for subsequent recycling and processing.

[0042] The second embodiment is based on the first embodiment, please refer toFigures 6 to 8 As shown, the collecting assembly 5 comprises two installation plates 51, the surfaces of the two installation plates 51 are provided with chip guide grooves 53, the outer surfaces of the installation plates 51 are fixedly installed with swing members 54, and the opposite surfaces of the swing members 54 are movably installed with arc-shaped chip receiving plates 52. When the steel plate is corrected, metal chips, oxide scales, iron chips and other impurities are generated. If these metal chips remain on the surface of the steel plate or the working parts of the correction machine, the surface of the steel plate can be pressed and scratched, which affects the appearance and surface quality of the finished product, and the metal chips can cause the correction machine roller to be unevenly stressed, which causes the steel plate to deviate and be stuck during the correction process, reduces the correction accuracy, and even causes secondary deformation. Therefore, when the rolling assembly 8 and the guiding assembly 4 cooperate to correct and process the steel plate, the rolling causes the metal chips attached to the steel plate to be extruded and scattered in the arc-shaped chip receiving plate 52, the inside 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 provided in an arc shape, so that the scattered metal chips are guided to the two sides, the collected chips can remove these impurities in time, ensure the smooth contact surface of the steel plate and the equipment, protect the flatness and surface integrity of the corrected steel plate, and the recycled metal chips can be reprocessed, realize resource recycling, and reduce production cost.

[0043] The installation plate 51 is arranged at the side of the outer surface of the beam frame 41, and the installation plate 51 is fixedly installed between the 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 arranged between the opposite surfaces of the installation plate 51 through the swing member 54.

[0044] The swing piece 54 comprises a positioning plate 542, the outer surface of the positioning plate 542 is fixedly installed with an outward expansion plate 541, the outer surface of the outward expansion plate 541 is fixedly installed with a support block 543, the support block 543 is fixedly installed at the bottom of the beam frame 41, the outer surface of the support block 543 is fixedly installed with a link block 545, the outer surface of the link block 545 is fixedly installed with an elastic band 544, and the elastic band 544 is fixedly installed on the outer surface of the arc-shaped scrap collecting plate 52. When the steel plate is corrected, the position and scattering range of the metal scraps are often not fixed. When the metal scraps are rolled and scattered, the metal scraps are adsorbed in the arc-shaped scrap collecting plate 52 of the magnetic material. At this time, the arc-shaped scrap collecting plate 52 on both sides is affected by the uneven force of the metal scrap accumulation and appears uneven force. At this time, the arc-shaped scrap collecting plate 52 will swing below the rotating roller 44. The efficiency of swing collection can reduce the accumulation of scraps, prolong the continuous operation time of the equipment, reduce the cleaning frequency of the stop, indirectly improve the production efficiency, and at the same time can avoid the existence of the collection blind area when the metal scraps are collected, so as to cause the residual scraps in the corners and gaps. The elastic band 544 is made of elastic material. When the elastic band 544 swings, it will stretch or shrink due to stress. The elastic deformation absorbs and releases energy, plays a buffering role, and when the arc-shaped scrap collecting plate 52 swings, the elasticity of the elastic band 544 can offset part of the impact force in the swinging process, so that the swing is more stable, and the arc-shaped scrap collecting plate 52 is prevented from being damaged by collision with the beam frame 41.

[0045] In the third embodiment, on the basis of the first and second embodiments, referring to Figures 9 to 13 As shown in the figure, the roller pressing assembly 8 comprises a guide limiting frame 81, the inside of the guide limiting frame 81 is movably installed with a lifting frame 82, the lifting frame 82 is provided with two, the inside of the two lifting frames 82 is provided with a guide groove 83, the opposite surfaces of the lifting frame 82 are provided with a cross frame 84, the inside of the cross frame 84 is fixedly installed with an inner connecting plate 85, the outer surface of the inner connecting plate 85 is fixedly installed with a sliding rod 86, and the outer surface of the cross frame 84 is slidably installed with a pressing plate roller group 87. The staff adjusts the distance between the lifting frame 82 and the rotating roller 44 through the hydraulic cylinder 3 according to the thickness of the steel plate, then the staff conveys the steel plate to the position between the rotating roller 44 and the pressing plate roller group 87 through the guide roller 43, starts the motor, drives the pressing plate roller group 87 to run through the motor, makes the sliding rod 86 drive the pressing plate roller group 87 to slide in the guide groove 83, and the roller pressing will force the curved steel plate between the rotating roller 44 and the pressing plate roller group 87 to bend in the direction opposite to the original deformation direction, so that the internal fibers of the steel plate produce tensile and compressive plastic deformation. The pressing plate roller group 87 is provided in an adjustable structure, which can be adjusted according to the thickness of the steel plate during the correction of the steel plate, so as to segmentally roll according to the thickness change of the steel plate, thereby improving the accuracy of the roller correction.

[0046] The lifting frame 82 is fixedly installed at the bottom of the hydraulic cylinder 3, and is movably installed in the guide limiting frame 81 through the hydraulic cylinder 3. The slide rod 86 extends to the outside of the lifting frame 82 through the guide groove 83, and is slidably installed in the guide groove 83.

[0047] The pressing plate roller set 87 comprises two extension plates 872, the top of each of the two extension plates 872 is fixedly installed with a sleeve block 871, the bottom of each of the extension plates 872 is fixedly installed with a mounting frame 873, the inside of each of the mounting frames 873 is provided with a rotating groove 877, the rotating groove 877 is provided with five groups, and each of the rotating grooves 877 is rotatably installed with a flattening roller 875. The outer surface of the mounting frame 873 is fixedly installed with a connecting pad 876, and the bottom of the connecting pad 876 is fixedly installed with a pressing plate arc block 874.

[0048] The sleeve block 871 is slidably installed on the outer surface of the cross frame 84, and the connecting pad 876 is fixedly installed between the adjacent surfaces of the flattening roller 875. The flattening roller 875 and the pressing plate arc block 874 are adapted to the friction of 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 roll and correct the steel plate. The pressing plate arc blocks 874 arranged on both sides of the mounting frame 873 are arranged between the two flattening rollers 875, which increases the contact area with the side edges of the steel plate during rolling, thereby improving the effect of extrusion correction of the curled edges of the steel plate.

[0049] In use, when the factory corrects the steel plate, the staff first adjusts the distance between the rolling assembly 8 and the conveying assembly 4 according to the thickness of the steel plate, and places the steel plate on the conveying assembly 4. After the steel plate is conveyed to the lower side of the rolling assembly 8 by the rotation of the conveying assembly 4, the staff starts the rolling assembly 8, and the rolling assembly 8 moves above the conveying assembly 4. At this time, the moving rolling assembly 8 rolls the steel plate above the conveying assembly 4, and the flattening rollers 875 arranged alternately apply repeated bending force to the steel plate to cause elastic-plastic deformation, thereby eliminating internal stress unevenness and surface unevenness. As the rolling assembly 8 moves, the steel plate slides on the conveying assembly 4 to the other side, thereby completing the correction work. The metal scraps scattered on the steel plate during rolling and correction fall into the collecting assembly 5 for subsequent recycling and processing.

[0050] The worker places the steel plate above the guide rollers 43, and then pushes the steel plate to drive the guide rollers 43 to rotate, and the steel plate is conveyed to above the rotating roller 44 through the cooperation between the multiple groups 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-joined arc plate 42. For the rolled steel plate, the curved surface design of the arc-shaped guide rollers 43 can match the curvature of the rolled plate, which facilitates the stable placement and gradual expansion of the rolled plate. The arc-shaped structure can disperse the weight of the steel plate, so as to avoid the direct pressure of the steel plate on the inlet end of the straightening equipment under the action of gravity. Through the buffer type feeding, the traditional plane feeding frame is replaced, the hard friction between the rolled plate and the frame body is reduced, and the deformation or scratching of the edge of the rolled plate due to uneven stress is avoided.

[0051] The worker adjusts the distance between the lifting frame 82 and the rotating roller 44 through the hydraulic cylinder 3 according to the thickness of the steel plate, and then the worker conveys the steel plate to between the rotating roller 44 and the pressure plate roller group 87 through the guide rollers 43. Then the worker starts the motor to drive the pressure plate roller group 87 to run, so that the slide rod 86 drives the pressure plate roller group 87 to slide in the guide groove 83. The roller pressing forces the curved steel plate between the rotating roller 44 and the pressure plate roller group 87 to bend in the direction opposite to the original deformation direction, so as to produce plastic deformation of stretching and compression of the internal fibers of the steel plate. The pressure plate roller group 87 is arranged in an adjustable structure, which can be adjusted according to the thickness of the steel plate during the straightening of the steel plate, so as to segmentally press the steel plate according to the thickness change of the steel plate, thereby improving the accuracy of the roller pressing straightening.

[0052] When the cross frame 84 and the slide rod 86 drive the extension plate 872 to move, the flattening rollers 875 cooperate with the rotating roller 44 to press and straighten the steel plate. The pressure plate arc blocks 874 arranged on both sides of the mounting frame 873 are arranged between the two flattening rollers 875, which increase the contact area with the side edges of the steel plate during roller pressing, so as to improve the effect of extrusion and straightening of the curled edges of the steel plate.

[0053] During the straightening of the steel plate, metal chips, oxide scales, iron chips and other impurities are generated. If these metal chips remain on the surface of the steel plate or the working parts of the straightening machine, the surface of the steel plate may be pressed and scratched, which affects the appearance and surface quality of the finished product. The metal chips will also cause uneven stress on the roller shaft of the straightening machine, resulting in deviation and jamming of the steel plate during the straightening process, reducing the straightening accuracy, and even causing secondary deformation. Therefore, when the roller pressing assembly 8 and the guide conveying assembly 4 cooperate to straighten and process the steel plate, the roller pressing causes the metal chips attached to the steel plate to be extruded and scattered in the arc-shaped chip collecting plate 52. The inside 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 arranged in a curved shape, so as to facilitate the scattered metal chips to be guided to both sides. The collected chips can remove these impurities in time, ensure the smooth contact surface between the steel plate and the equipment, and ensure the flatness and surface integrity of the straightened steel plate. At the same time, the recovered metal chips can be re-melted and processed, realizing resource recycling and reducing production cost.

[0054] When the steel plate is corrected, the position and the scattering range of the metal chips are often not fixed. When the metal chips are rolled and scattered, the metal chips are adsorbed in the arc-shaped chip receiving plate 52 made of magnetic material. At this time, the arc-shaped chip receiving plate 52 will swing under the rotating roller 44, and the high efficiency of swinging collection can reduce the accumulation of chips, prolong the continuous operation time of the equipment, reduce the cleaning frequency of shutdown, indirectly improve the production efficiency, and at the same time, can avoid the existence of collection blind area when collecting the metal chips, resulting in the residual chips in the corners and gaps. The elastic band 544 is made of elastic material. When the elastic band 544 swings, it will stretch or contract due to stress. Through elastic deformation, energy can be absorbed and released, and a buffering effect is achieved. When the arc-shaped chip receiving plate 52 swings, the elasticity of the elastic band 544 can offset part of the impact force in the swinging process, so that the swinging is more stable, and the arc-shaped chip receiving plate 52 is prevented from being damaged by collision with the beam frame 41.
