Description

Technical Field

[0001] This invention relates to the field of steel structure building component processing technology, and more specifically, to a forming and processing equipment for steel structure building components. Background Technology

[0002] Horizontally curved corrugated sheets are metal sheet components with a continuous wavy cross-section and an overall arc-shaped profile along the horizontal direction. Due to their high bending and shear stiffness and lightweight advantages brought by their corrugated structure, they are widely used in engineering fields such as prefabricated houses, lightweight steel structure buildings, large warehouse roof cladding, and large steel structure factory walls. Among these, prefabricated houses and lightweight steel structure buildings extensively use profiled corrugated sheets as roof panels, wall panels, and corner curved panels, placing higher demands on the forming precision, surface quality, and bending processing performance of the sheets.

[0003] Currently, the industry uses a segmented continuous forming process for horizontally bent corrugated sheets. The processing equipment mainly consists of a combination of a corrugated forming machine and a bending machine arranged in series. During processing, the metal plate is first fed into the corrugated forming machine, so that the metal plate is gradually bent under continuous cold pressure to form a corrugated substrate with a fixed wave height and wave pitch. After corrugation is completed, the sheet is continued to be conveyed to the bending machine at the rear end to finally obtain the finished corrugated sheet.

[0004] However, during long-term cold pressing of metal sheets in corrugated forming machines, iron filings and oxide scale from the rolling process mix with lubricating oil and adhere to the roller surface, gradually forming hardened agglomerated impurities. As the forming rollers continue to rotate, these hardened impurities rotate synchronously with the rollers, periodically pressing against the sheet material and creating regularly spaced indentations on the surface. These indentations not only damage the appearance of the workpiece but also lead to problems such as color difference and pinholes in subsequent coating processes. Furthermore, the indentation locations create stress concentration areas, which can easily cause micro-cracks along the indentations or even sheet cracking when the sheet is conveyed to a bending machine for bending, resulting in product waste. For prefabricated houses and lightweight steel structure buildings, surface indentations and bending cracks directly affect the waterproofing, wind resistance, and aesthetics of the building envelope. Therefore, there is an urgent need for forming and processing equipment for steel structure building components to solve these problems. Summary of the Invention

[0005] This invention provides a forming and processing equipment for steel structure building components. By setting appropriately meshing auxiliary rollers at the gap between the lower rollers of adjacent forming roller groups, controlling the installation gap and assembly height, and combining this with a friction-bonding layer, the device combines roller surface impurity removal and sheet support and positioning functions. In continuous cold-pressing forming of corrugated sheets, this effectively reduces indentation and misalignment problems on the sheet metal, thereby solving the problems mentioned in the background art. Corrugated forming rollers are prone to adhering to hard impurities such as iron filings and oxide scale. When rolling the sheet material, they form indentations upon contact with the sheet material, which not only affects the appearance and coating quality, but also easily leads to cracking and scrapping of the sheet material during bending processing.

[0006] To achieve the above objectives, the forming and processing equipment for the steel structure building component includes a device body. The device body has a corrugated forming unit and a horizontal bending unit arranged sequentially along the plate conveying direction. The corrugated forming unit includes two lateral frames, which are connected by a transverse frame. Multiple sets of forming rollers are assembled between the two lateral frames. Each set of forming rollers includes an upper roller and a lower roller that cooperate with each other. An auxiliary mechanism is assembled in the installation gap of each set of forming rollers. When the flat sheet passes through each of the forming roller groups in sequence, the upper roller and the lower roller cooperate to continuously press and form the sheet to form a corrugated sheet. The auxiliary mechanism is set between the lower rollers of two adjacent forming roller groups. When the corrugated sheet is conveyed through the gap between two adjacent forming roller groups in the corrugated forming unit, the auxiliary mechanism can support the lower surface of the corrugated sheet and guide it at the same time. In addition, the auxiliary mechanism can cooperate with the surface of the lower roller to simultaneously clean the surface of the lower roller.

[0007] In the above technical solution, by using an auxiliary mechanism located in the gap between the rollers, the plate support and positioning and the surface cleaning of the forming roller can be realized simultaneously during the continuous forming and conveying of the corrugated plate, thereby reducing defects in the formed corrugated plate and improving the regularity of the corrugated pattern and the surface quality of the workpiece.

[0008] Based on this, the outer circumferential surfaces of the upper and lower rollers each have alternating concave and convex areas distributed along the axial direction. The convex areas of the upper roller are opposite to the concave areas of the lower roller, and the concave areas of the upper roller are opposite to the convex areas of the lower roller. A forming cavity matching the cross-sectional shape of the corrugated plate is formed between the upper and lower rollers. When the flat plate enters the forming cavity, the upper and lower rollers rotate relative to each other to cold press the plate to produce corrugations.

[0009] In addition, the auxiliary mechanism includes an auxiliary roller, the outer circumferential surface of which is provided with a plurality of rings spaced apart along the axial direction, the position of each ring corresponding axially to the concave part of the adjacent lower roller.

[0010] Preferably, the auxiliary roller is installed at a lower height than the lower roller, and the highest point of the ring body is on the same horizontal plane as the lowest point of the concave part of the adjacent lower roller; when the corrugated plate is conveyed through the gap between two adjacent forming roller groups, the lowest point of the trough on the lower surface of the corrugated plate is in contact with the top of the ring body.

[0011] Specifically, each of the ring bodies has an adhesive layer on its outer surface. The surface of the adhesive layer has frictional properties, which allows the auxiliary roller to be passively rotated when the corrugated plate comes into contact with the ring body.

[0012] Furthermore, the auxiliary roller is made of wear-resistant tool steel, and the surface hardness of the auxiliary roller is lower than that of the lower roller.

[0013] As a further improvement to this technical solution, when the auxiliary roller is installed in place, the ring body can be embedded in the recess of the lower roller, and the auxiliary roller and the adjacent lower roller are not in contact, and an installation gap is formed between the surface of the auxiliary roller and the adjacent lower roller.

[0014] The pre-reserved installation gap between the auxiliary roller and the lower roller can prevent hard contact between the auxiliary roller and the adjacent lower roller from causing movement jamming, ensuring the smooth operation of the forming roller group; after the hard impurities attached to the lower roller surface form protrusions, they can abut against the auxiliary roller, and the impurities can be peeled off by the relative rotation of the roller body, achieving the purpose of online impurity removal.

[0015] In another technical solution, the surface of the transverse frame is equipped with multiple air knife structures, which are arranged axially at intervals around the auxiliary roller; the air outlets of the air knife structures face the contact area between the auxiliary roller and the adjacent lower roller, and are used to blow away the debris scraped off the surface of the lower roller by the auxiliary roller in a timely manner.

[0016] The air blowing direction of the air knife structure is inclined upward relative to the horizontal plane, pointing towards the meshing outlet side between the auxiliary roller and the lower roller.

[0017] This technical solution, by arranging air knife structures inclined upward toward the roller body meshing outlet side at axial intervals on the auxiliary roller, can promptly blow away various debris and impurities scraped off by the auxiliary roller, effectively reducing the secondary adhesion of debris to the roller surface or contamination of the board, and ensuring the cleanliness of the roller surface and the forming quality of the board.

[0018] As a further improvement to this technical solution, the horizontal bending unit includes a bending frame, and one upper bending roller and two lower bending rollers installed in the bending frame. The two lower bending arc rollers are arranged side by side in the same horizontal plane, and the upper bending arc roller is arranged above the two lower bending arc rollers, and the axes of the three are parallel to each other; As the formed corrugated plate passes through the first lower bending roller, the upper bending roller, and the second lower bending roller in sequence, the upper bending roller applies downward pressure, causing the corrugated plate to bend horizontally.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. In the forming and processing equipment for this steel structure building component, an auxiliary roller is installed at the gap between the lower rollers of two adjacent forming roller groups. The ring body of the auxiliary roller and the concave and convex structure of the lower roller are adapted to each other to form an interlocking structure, and a small installation gap is reserved between the two. When hard impurities such as iron filings, oxide scale, and sludge adhere to the surface of the lower roller and form protrusions, the impurities will fill the gap and abut against the surface of the auxiliary roller. Relying on the active rotation of the lower roller and the passive rotation of the auxiliary roller to form a relative scraping, the impurities adhering to the surface of the lower roller can be continuously scraped off, reducing the occurrence of indentations caused by the lower roller pressing the plate during cold pressing, thereby improving the surface quality of the finished product.

[0020] 2. In the forming and processing equipment for this steel structure building component, by setting the overall installation height of the auxiliary roller to be lower than that of the lower roller, the highest point of the auxiliary roller ring is flush with the lowest point of the concave part of the lower roller. When the corrugated plate passes through the gap of the roller group, the trough can fit into the auxiliary roller ring. Moreover, the outer bonding layer of the ring has friction characteristics. The friction force of the plate conveying can drive the auxiliary roller to rotate synchronously and passively, forming a continuous contour-following moving support for the corrugated plate suspended in the gap. Relying on the friction force of the contact surface to constrain the lateral movement of the plate, the plate deviates in the gap section of the forming roller group. Attached Figure Description

[0023] 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.

[0024] When corrugated forming machines cold press metal building panels for extended periods, the iron filings and oxide scale that detach from the panels mix with the lubricating oil, forming hard, agglomerated impurities on the surface of the forming rollers. As the rollers continue to rotate, these impurities periodically crush the panels, creating regular indentations on their surface. This not only damages the appearance of the workpiece but also causes problems such as color difference in coating and pinholes. At the same time, stress concentration occurs at the indentations, making it easy for micro-cracks or even overall cracking to appear when the panels are subsequently bent in a bending machine, ultimately resulting in product scrap.

[0025] In view of this, the present invention provides a forming and processing equipment for steel structure building components, see reference. Figures 1-4 As shown, the device includes a main body 1, which has a corrugated forming unit 11 and a horizontal bending unit 12 arranged sequentially along the conveying direction of the sheet material. The corrugated forming unit 11 includes two side frames 112, which are connected by a transverse frame 113. Multiple sets of forming rollers 111 are assembled between the two side frames 112. Each set of forming rollers 111 includes an upper roller 21 and a lower roller 22 that cooperate with each other. An auxiliary mechanism 13 is assembled in the installation gap of each set of forming rollers 111. When the flat plate passes through each of the forming roller groups 111 in sequence, the upper roller 21 and the lower roller 22 cooperate to continuously press and form the plate to form a corrugated plate, ensuring that the corrugated forming size is consistent. The auxiliary mechanism 13 is located between the lower rollers 22 of two adjacent forming roller groups 111. When the corrugated plate is conveyed through the gap between the two adjacent forming roller groups 111 in the corrugated forming unit 11, the auxiliary mechanism 13 can support the lower surface of the corrugated plate and guide it at the same time, effectively reducing the deviation of the plate during the conveying process. In addition, the auxiliary mechanism 13 can cooperate with the surface of the lower roller 22 to clean the surface of the lower roller 22 simultaneously, reducing the defects of the plate caused by impurities on the roller surface.

[0026] It should be noted that the auxiliary mechanism 13 is located at the lower roller 22 because iron filings, oxide scale, and oil stains generated during the cold pressing of the sheet metal settle downwards due to gravity, making them more likely to accumulate and adhere to the surface of the lower roller 22, which is the main cause of indentation defects in the sheet metal. On the other hand, the upper roller 21 is located above the sheet metal, making it difficult for debris and oil stains to adhere and accumulate. Hard lumps of impurities will not form on the surface of the upper roller 21, and its impact on the forming quality of the sheet metal is relatively small. Therefore, the core problem can be solved by setting the auxiliary mechanism 13 on the lower roller 22 for impurity removal, while simplifying the equipment structure of the main body of the device 1.

[0027] In each of the forming roller groups 111, the upper roller 21 and the lower roller 22 are both long cylindrical rotary rollers, which are arranged vertically in opposite directions. The outer circumferential surfaces of the upper roller 21 and the lower roller 22 are processed with concave parts 25 and convex parts 24 that are evenly distributed along their own axial length. The concave parts 25 and convex parts 24 are continuously arranged in the circumferential direction to form a complete corrugated rotary surface.

[0028] See Figure 4 As shown, in the assembled state, the outer contour area of ​​each protrusion 24 of the upper roller 21 is directly aligned with the corresponding axially positioned concave area 25 of the lower roller 22. Simultaneously, the inner concave area of ​​each concave area 25 of the upper roller 21 is also aligned with the corresponding axially positioned protrusion 24 of the lower roller 22. The two sets of convex and concave structures are aligned and fitted together, forming a forming cavity 23 between the upper and lower rollers 22. The forming cavity 23 extends axially through the entire roller body, and its internal cross-sectional profile, wave height, and wave pitch parameters are consistent with the finished cross-sectional profile of the corrugated sheet to be processed, providing a forming reference for the cold pressing and shaping of the sheet.

[0029] Combination Figure 5 During the operation of the equipment, the upper roller 21 and the lower roller 22 are driven by an independent drive mechanism to rotate in opposite directions. During the rotation of the upper roller 21 and the lower roller 22, the flat plate is driven to move forward continuously along the preset conveying direction by the friction of the contact surface. While moving, the plate is subjected to the squeezing force applied by the roller to complete the shape change.

[0030] Because the metal plate itself has a certain structural rigidity, a single rolling action cannot complete the full-width corrugation shaping of the plate in one go, and a large deformation at one time will cause uneven stress distribution inside the plate. Therefore, the device body 1 is equipped with multiple forming roller groups 111 that can bend and shape the plate in stages, allowing the plastic deformation of the plate to be completed gradually, making the final corrugated structure more regular.

[0031] During operation, the original metal plate is smoothly fed into the first forming roller group 111 along the feeding direction of the equipment. The plate gradually enters the forming cavity 23 formed by the upper roller 21 and the lower roller 22. During this process, the upper roller 21 and the lower roller 22, which rotate in opposite directions, continuously apply radial extrusion force to the plate. Under the action of mechanical extrusion force, the plate gradually undergoes plastic deformation. The originally flat plate surface forms a preliminary corrugated structure according to the contour of the forming cavity 23. The plate with the preliminary corrugated shape will continue to be conveyed backward under the driving force of the roller friction and enter each subsequent forming roller group 111 in sequence. After continuous rolling and pressing by multiple sets of rollers, the corrugated shape of the plate is continuously corrected and shaped, and finally a corrugated plate with cross-sectional dimensions that meet the design requirements is formed, which is then continuously conveyed to the next process.

[0032] Combination Figure 6 and Figure 7 It can be seen that the core structure of the auxiliary mechanism 13 is the auxiliary roller 31. The auxiliary mechanism 13 is assembled in the installation gap between two adjacent forming roller groups 111, specifically in the area below the two lower rollers 22. The auxiliary roller 31 is also a long cylindrical rotating part, and its outer circumferential surface is machined with multiple rings 311 evenly distributed along the axial direction. The axial installation positions of all rings 311 correspond to the recesses 25 on the surface of the adjacent lower rollers 22, and as shown... Figure 8 As shown, the overall installation height of the auxiliary roller 31 is lower than that of the lower rollers 22 on both sides, so that the highest point of the outer circumference of the ring body 311 of the auxiliary roller 31 and the lowest point of the concave part 25 of the adjacent lower roller 22 are on the same horizontal reference plane.

[0033] When the corrugated plate, after initial shaping, is conveyed to the gap area between the two forming roller groups 111, the lowest trough area on the lower surface of the corrugated plate will adhere to the top surface of the ring 311, and the two will be in contact. The auxiliary roller 31 can support the corrugated plate, which is suspended in the gap area between the forming roller groups 111, and fill the support gap area between the two adjacent forming roller groups 111. Throughout the entire process of conveying the corrugated plate from one set of lower rollers 22 to another set of lower rollers 22, the trough on the lower side of the plate always remains in contact with the ring 311. The plate has a continuous and close support surface along the entire conveying path, which keeps the overall conveying posture of the plate stable and allows the corrugated structure to maintain its original shape in the transition area.

[0034] In addition, return Figure 7It can be seen that the outer surface of each ring 311 is covered with a bonding layer 312 (a high wear-resistant polyurethane friction coating material can be preferred). The bonding layer 312 material has stable friction properties. When the equipment is operating normally, the auxiliary roller 31 has no independent power source and remains stationary in the initial state. When the lower surface of the corrugated plate traveling at a constant speed comes into contact with the top surface of the ring 311, the linear motion of the plate will generate a contact force with the stationary ring 311. The friction force formed between the contact surfaces will continue to act on the ring 311. This force can drive the auxiliary roller 31 to follow the conveying rhythm of the plate and make circumferential rotation, realizing the passive rotation of the auxiliary roller 31.

[0035] The contact friction generated by the bonding layer 312 can not only drive the auxiliary roller 31 to rotate synchronously and passively, but also form a large-scale surface contact support with the trough of the corrugated plate. During the continuous conveying process, the plate will have a lateral displacement tendency due to factors such as the coaxiality deviation of the roller assembly, the residual stress inside the plate, and the conveying inertia. When the plate has a lateral displacement tendency, a corresponding lateral friction force will be formed between the trough and the contact surface of the ring 311. This lateral force can balance the lateral component force on the plate. At the same time, the plate and the rotating auxiliary roller 31 keep moving synchronously, and there will be no obvious relative sliding between them. The lateral position of the plate can be constrained, and the conveying trajectory can maintain the initial set direction.

[0036] Furthermore, the auxiliary roller 31 is made entirely of wear-resistant tool steel (such as Cr12MoV), possessing high overall structural strength, excellent wear resistance, and good impact resistance, enabling it to withstand long-term operation conditions involving frequent friction with metal scraping and the roller surface. In terms of surface hardness design, the surface hardness of the auxiliary roller 31 is set lower than that of the lower roller 22. When the surfaces of the auxiliary roller 31 and the lower roller 22 come into contact or scrape, the surface of the auxiliary roller 31, with its lower material hardness, will preferentially experience minor wear. As the core reference component for corrugated forming, the surface contour and dimensional accuracy of the lower roller 22 directly determine the quality of corrugated forming. The differentiated hardness design allows the surface morphology and dimensional parameters of the lower roller 22 to maintain their original state over a long period, preserving the overall forming benchmark of the equipment.

[0037] When the auxiliary roller 31 completes the overall assembly and is in the working position, refer to Figure 9It can be seen that the outer ring 311 extends into the recess 25 of the adjacent lower roller 22. There is no solid contact between the outer surface of the ring 311 and the inner wall of the recess 25 of the lower roller 22; both maintain uniform gaps in the radial and circumferential directions, forming an installation gap 33. During long-term operation, iron filings from the sheet metal and oxide scale from rolling will gradually adhere to the surface of the lower roller 22. These impurities, mixed with the lubricating oil, will gradually accumulate and form hard protrusions. When the roller area with these protrusions rotates to the installation gap 33, the protrusions extend into the gap and contact the surface of the auxiliary roller 31. The lower roller 22 is an active rotating component, and the auxiliary roller 31 is a passive rotating component. The difference in rotation speed between the two rollers creates relative motion, which continuously peels off the hard impurities adhering to the surface of the lower roller 22, reducing the phenomenon of these adhering impurities rotating synchronously with the lower roller 22 and repeatedly contacting and crushing the sheet metal.

[0038] Under the action of the drive mechanism, the lower roller 22 maintains continuous active circumferential rotation. Impurities such as iron filings, oxide scale, and sludge adhering to its surface will follow the roller body in circumferential circulation. When the area with hard, protruding impurities rotates to the corresponding recess 25 position of the ring body 311, the protruding part of the impurity enters the installation gap 33 and comes into close contact with the surface of the auxiliary roller 31. The relative rotation between the lower roller 22 and the auxiliary roller 31 generates a continuous scraping and shearing action, and the impurities originally adhered to the roller surface gradually fall off the surface of the lower roller 22. The peeled debris temporarily stays in the contact area between the two roller bodies, while the auxiliary roller 31 continues to maintain a passive rotation state, cooperating with the lower roller 22 to complete the continuous impurity peeling operation throughout the process.

[0039] Back Figure 4 and combined Figure 5 As shown, multiple sets of air knife structures 32 are assembled on the surface of the transverse frame 113 of the supporting side frame 112. The air knife structures 32 are arranged at equal intervals along the entire length of the auxiliary roller 31, with the axial centerline of the auxiliary roller 31 as the reference. The installation position of each set of air knife structures 32 corresponds to the contact area between a ring 311 and the lower roller 22. The air outlet of the air knife structure 32 faces the meshing contact area between the auxiliary roller 31 and the adjacent lower roller 22. Simultaneously, the air outlet direction of the air knife structure 32 is inclined upwards relative to the horizontal plane, causing the airflow to ultimately blow towards the discharge side of the meshing position of the two rollers. This creates a directional flow for the loose debris peeled off from the roller surface, changing the trajectory of the debris's natural fall and allowing it to detach from the working area of ​​the plate and the roller. Furthermore, during normal operation, the air knife structure 32 is connected to a stable external air source, continuously outputting a directional airflow with a uniform flow rate.

[0040] Finally, as Figure 10As shown, the horizontal bending unit 12 is arranged at the material output end of the corrugated forming unit 11, and mainly consists of a bending frame 122, an upper bending roller 41 and two lower bending rollers 42. The curved frame 122 serves as the overall load-bearing base, used to fix all the curved rollers and ensure the installation accuracy and operational stability of each roller. Two lower curved rollers 42 are installed side by side at a preset interval on the lower part of the curved frame 122, with their axes on the same horizontal plane. The roller spacing is designed to match the width of the corrugated plate and the finished curved radius. The upper curved roller 41 is mounted above the middle position of the two lower curved rollers 42, forming a complete three-point rolling bending structure.

[0041] The corrugated sheet, processed by the previous corrugated forming unit 11, is continuously conveyed to the horizontal bending unit 12. The bottom surface of the sheet is placed sequentially on the surfaces of two lower bending rollers 42. During operation, the lower bending rollers 42 drive the sheet forward. The upper bending roller 41 can apply constant downward pressure according to production requirements. The pressure acts on the upper surface of the corrugated sheet. Under the combined action of the conveying force of the lower roller and the pressure of the upper roller, a uniform force is generated inside the sheet, resulting in horizontal plastic deformation and gradually forming the arc-shaped profile required by the design.

[0042] Working principle: First, the metal plate to be processed is conveyed along the feeding direction to the corrugated forming unit 11 of the device body 1. The metal plate enters each of the forming roller groups 111 in sequence. The upper roller 21 and the lower roller 22 in each forming roller group 111 keep rotating in opposite directions under the action of an independent drive mechanism. The plate is driven to move forward continuously by the friction between the roller body and the plate. At the same time, the concave parts 25 and convex parts 24 distributed on the surface of the upper roller 21 and the lower roller 22 cooperate to form a molding cavity 23. During the rotation of the roller body, radial extrusion force is applied to the plate, causing the plate to gradually produce plastic deformation. When the corrugated plate is conveyed to the installation gap between two adjacent forming roller groups 111, the auxiliary roller 31 arranged between the two lower roller groups 22 uses its own height layout to form a complete support for the trough area on the lower surface of the corrugated plate, filling the support gap between the roller groups; the bonding layer 312 on the surface of the auxiliary roller 31 has friction characteristics. After the corrugated plate in motion comes into contact with the auxiliary roller 31, the friction of the contact surface drives the auxiliary roller 31 to rotate passively. The lateral force generated by the contact surface can constrain the lateral position of the plate and maintain the predetermined conveying trajectory of the plate.

[0043] Meanwhile, the ring 311 of the auxiliary roller 31 extends into the recess 25 of the lower roller 22. The installation gap 33 between the two continuously peels off the impurities adhering to the surface of the lower roller 22 through the relative motion formed by the active rotation of the lower roller 22 and the passive rotation of the auxiliary roller 31. After the impurities are peeled off, the air knife structure 32 arranged at intervals along the axial direction of the auxiliary roller 31 on the transverse frame 113 continuously outputs the inclined upward directional airflow. The airflow is aimed at the meshing discharge area of ​​the two rollers, directing the scattered debris and blowing it away from the working area. In addition, the air knife structure 32 can also directly blow away the unstable impurities adhering to the lower roller 22. After corrugated forming and roller surface cleaning, the corrugated plate continues to be conveyed to the rear horizontal bending unit 12. The corrugated plate continues to move under the drive of the lower bending roller 42, while the upper bending roller 41 applies constant pressure downward, causing the corrugated plate to undergo horizontal plastic deformation under the combined action of conveying force and pressure, gradually forming the arc profile required by the design.
