Description

Technical Field

[0001] The present invention relates to the technical field of steel structure correction, in particular to correction equipment for steel structure processing and a use method thereof. Background Art

[0002] Steel structure correction is a key process that aims to lengthen or shorten steel fibers through external force or heating, thereby eliminating deformations such as bending and warping, and ensuring that components are straight and meet technical standards. Correction methods mainly include mechanical correction, flame correction, manual correction and mixed correction methods.

[0003] Typically, mechanical straightening is applied to general panels and components, using stamping to straighten them.

[0004] The existing patent (publication number: CN115430735B) discloses a straightening machine for steel structure processing, including a base, a straightening mechanism installed on the base, a guide mechanism connected to the straightening mechanism, a sliding mechanism installed on the straightening mechanism, a protective mechanism installed on the straightening mechanism, a locking mechanism installed on the straightening mechanism, and a lubricating mechanism installed on the straightening mechanism; through the cooperation of the straightening mechanism and the sliding mechanism, it is convenient to flatten and correct the steel structure, and through the protective mechanism, it is convenient to protect the two ends of the straightening mechanism and subsequent disassembly and assembly, which is beneficial to support and correct steel structures of different shapes, and through the guide mechanism, it is beneficial to lift and move the steel structure, and through the driving of the locking mechanism by the guide mechanism, it is beneficial to limit the position of the straightening mechanism during operation, and through the work of the guide mechanism, it is beneficial to inject air into the lubricating mechanism so that the lubricating oil can be discharged. In the above-mentioned equipment, the steel structure is corrected by pressing down to make the surface of the steel structure in the same plane. However, during the correction process, due to the different bulge ranges in different areas of the steel structure surface, the force may be uneven during correction. If the size of the pressed correction part is too long, the clamping force in the middle part will be insufficient, causing the steel structure to warp, affecting the subsequent correction effect.

[0005] In view of this, we propose a correction device for steel structure processing and a method of using the same. Summary of the invention

[0013] A method for using a correction device for steel structure processing comprises the following steps: S1. The steel structure to be corrected is placed on the surface of the correction base. The clamping jaw cylinder pushes and pulls the push-pull inclined block, driving the clamping jaw connection blocks on both sides to move away from or close to each other, driving the synchronous clamping jaws to clamp the steel structure when they are close at the same time; S2. Start the driving cylinder to drive the lifting platform to descend, driving the correction contact seat of the vertical movable rod in contact with the steel structure to adapt to the contour shape of the steel structure surface. When the adaptation is completed, the secondary downward pressure shell presses down the rotating mounting column on the surface of the vertical movable rod, and presses down the rotating mounting column from high to low in sequence until all the rotating mounting columns are at the same height. The driven gear will mesh with the fixed rack to drive the track mounting column to rotate. The track mounting columns are sleeved with friction tracks. When they contact the friction wheels on the rotating mounting columns, the friction wheels and the rotating mounting columns will be driven to rotate by friction. The rotating mounting columns are connected to the correction contact seat through the vibration connecting rod. During the rotation of the rotating mounting column, the correction contact seat will be continuously lifted and lowered, and the buffer spring will press the correction contact seat down after it is lifted, so that it keeps moving up and down to generate vibration, and continuously vibrates and knocks on the surface of the steel structure. S3. In the process of the secondary pressing shell being pressed down, the connection between the articulated connecting rod and the gear connecting rod is bent at the initial state. As the pressing angle of the secondary pressing shell gradually increases until it reaches 180 degrees, the articulated connecting rod and the gear connecting rod are in line with each other. The force of the steel structure to push up the secondary pressing shell will be parallel to the articulated connecting rod and the gear connecting rod. The angle is zero and the articulated connecting rod and the gear connecting rod cannot be bent. When the rotating control plug block is lowered, the one-way rotating teeth cannot rotate upward. When the lifting platform rises, the one-way rotating teeth cannot rotate downward, and the meshing gears will be moved to rotate. The meshing gears mesh with the meshing gears of the same group to rotate. The rising of the secondary pressing shell will cause the articulated connecting rod and the gear connecting rod to bend, thereby no longer blocking the articulated connecting rod and the gear connecting rod from rising. S4. When the lifting platform descends, the vertical connecting arm will be driven down, so that the active downward pressure column at the bottom of the vertical connecting arm will descend in the vertical area of ​​the rotating path groove on the driven rotating column, without playing a flipping role, and the toggle protrusion will push out the blocking block so as not to affect the descent of the toggle protrusion in the vertical area of ​​the rotating path groove. When the lifting platform rises, the toggle protrusion will also rise when the vertical connecting arm is pulled up, and will no longer push up the blocking block, and can only rise in the inclined area of ​​the rotating path groove, driving the driven rotating column to rotate, and using the active bevel gear and the driven bevel gear to change the rotating path, and by rotating the connecting shaft to rotate the clamp mounting plate, the clamped steel structure can be flipped 180 degrees when the lifting platform is folded.

[0014] Compared with the prior art, the present invention has the following beneficial effects: In the present invention, through the cooperation of the correction process mechanism and the correction vibration mechanism, when correcting the steel structure, the part that is pressed down to correct is firstly made to fit the surface of the steel structure to adapt to the steel structure with different surface finishes, so as to prevent warping due to uneven force in different areas during the pressing process, and in the pressing process, the articulated rod is used to clamp the descending part after the correction is completed to lock the height and prevent the steel structure from rebounding.

[0015] In the present invention, through the setting of the correction vibration mechanism, during the downward pressure correction process, the linear descent is converted into reciprocating up and down vibration, so that during the downward pressure correction process, the surface of the steel structure is hammered, the force is increased, and the correction effect is improved.

[0016] In the present invention, through the setting of the linkage flipping mechanism, during use, when pressing down for correction does not work, after one side correction is completed, the clamped steel structure will be driven to flip, correcting different sides of the steel structure, thereby increasing the correction effect.

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technical personnel in this field without creative work are within the scope of protection of the present invention.

[0020] See also Figures 1 to 14The present invention provides a technical solution: a correction device for steel structure processing and a method of using the same, comprising a device housing 1, a driving cylinder 11 is fixedly connected to the top surface of the device housing 1, a base limiting column 12 is fixedly connected to the bottom surface of the device housing 1, a base supporting spring 121 is sleeved on the outer surface of the base limiting column 12, a correction base 122 is slidably connected to the outer surface of the base limiting column 12, a base supporting cylinder 123 is fixedly connected to the outer surface of the device housing 1, a base supporting wedge 1231 is fixedly connected to the output end of the base supporting cylinder 123, and a base supporting spring 121 is arranged on the output end of the driving cylinder 11. There is a correction process mechanism 2, the outer surface of the correction process mechanism 2 is provided with a correction vibration mechanism 3, the outer surface of the correction process mechanism 2 is provided with a linkage flip mechanism 4, the device housing 1 is used to install and protect the remaining components, the top driving cylinder 11 presses down and drives the correction process mechanism 2, the correction process mechanism 2 drives the correction vibration mechanism 3 to contact with the surface of the steel structure to adapt to the surface contour to prevent warping, and corrects the steel structure by vibrating while pressing down twice, the linkage flip mechanism 4 clamps the steel structure, and does not work when the driving cylinder 11 drives to press down, and flips the clamped steel structure after retracting; The number of the driving cylinders 11 is two, and the two driving cylinders 11 are symmetrically distributed with the central axis of the device housing 1 as the symmetry axis. The number of the base limiting columns 12 and the base supporting springs 121 are both two, and the two base limiting columns 12 and the two base supporting springs 121 are symmetrically distributed with the central axis of the device housing 1 as the symmetry axis. The base limiting column 12 penetrates the inner surface of the correction base 122 and is slidably connected to the inner wall thereof. The number of the base supporting cylinders 123 is two, and the two base supporting cylinders 123 are symmetrically distributed with the central axis of the device housing 1 as the symmetry axis. The surface of the base supporting wedge block 1231 is an inclined surface, and the base supporting wedge block 123 1 is slidably connected to the bottom surface of the correction base 122, and the symmetrical driving cylinders 11 are driven simultaneously on both sides of the correction process mechanism 2 to increase the downward pressure. The steel structure to be corrected is placed on the surface of the correction base 122. The correction base 122 can slide on the base limiting column 12 and be lifted up by the base supporting spring 121. The base limiting column 12 limits the moving path of the correction base 122 so that it can only move vertically but cannot rotate. The base supporting cylinder 123 changes the height of the supporting correction base 122 by pushing and pulling the base supporting wedge block 1231 to adapt to steel structures of different sizes and adapt to the diagonal size during rotation when the steel structure is flipped.

[0021] The correction process mechanism 2 includes a lifting platform 21, which is fixedly connected to the output end of the driving cylinder 11, a platform sliding column 211 is fixedly connected to the bottom surface of the lifting platform 21, a secondary pressing plate 212 is fixedly connected to the outer surface of the lifting platform 21, a driven lifting platform 22 is slidably connected to the outer surface of the platform sliding column 211, a downward pressure limit column 221 is fixedly connected to the inner surface of the driven lifting platform 22, a correction sliding groove 222 is provided on the outer surface of the driven lifting platform 22, a secondary pressing shell 23 is slidably connected to the outer surface of the driven lifting platform 22, a meshing gear 24 is rotatably connected to the outer surface of the meshing gear 24, a gear connecting rod 241 is fixedly connected to the outer surface of the gear connecting rod One end of 241 is hingedly connected to an articulated connecting rod 242, and the other end of the articulated connecting rod 242 is hingedly connected to a connecting base 243. The outer surface of the lifting platform 21 is fixedly connected to a rotation control plug block 244, and the inner surface of the rotation control plug block 244 is provided with a rack rotation groove 2441, and the inner surface of the rack rotation groove 2441 is rotatably connected with a one-way rotating tooth 2442. Through the setting of the correction process mechanism 2, during use, the driving cylinder 11 drives the lifting platform 21 to move up and down. While moving down, the driven lifting platform 22 is located at the bottom of the platform sliding column 211 until it drives the correction vibration mechanism 3 to contact the surface of the steel structure. The correction vibration mechanism 3 will use the surface contour of the steel structure until the highest point will be lowered twice. The pressure shell 23 is lifted up. At this time, the driven lifting platform 22 cannot continue to move downward, but the lifting platform 21 can still be connected by the sliding connection at the platform sliding column 211, and the driven lifting platform 22 continues to move downward, and presses down the secondary pressing shell 23 through the secondary pressing plate 212. The secondary pressing shell 23 presses down the correction vibration mechanism 3 that has adapted to the surface contour of the steel structure from high to low, and finally makes the surface contour horizontal to achieve the correction effect. In the process of the secondary pressing shell 23 pressing down, the secondary pressing shell 23 pulls the hinged connecting rod 242 and the gear connecting rod 241 through the connecting base 243. In the initial state, the connection between the hinged connecting rod 242 and the gear connecting rod 241 is bent, and as the secondary pressing shell 23 presses down the angle The secondary pressing shell 23 gradually tends to 180 degrees. When the secondary pressing shell 23 reaches the bottom limit position, the hinge connecting rod 242 and the gear connecting rod 241 are in the same line. The force of the steel structure to push up the secondary pressing shell 23 will be parallel to the hinge connecting rod 242 and the gear connecting rod 241. The angle is zero and the hinge connecting rod 242 and the gear connecting rod 241 cannot be bent, which plays the role of locking the current height of the secondary pressing shell 23 in each section to prevent the steel structure from rebounding and bending again due to the insufficient clamping force provided in the middle of the secondary pressing shell 23 being too long. The rotating control plug block 244 will rise and fall synchronously with the lifting platform 21. When descending, the one-way rotating tooth 2442 will contact the meshing gear 24, but the internal rack rotating groove 2441 allows it to rotate upward.At this time, the one-way rotating tooth 2442 does not work when it rotates upward. When the lifting platform 21 rises, the one-way rotating tooth 2442 cannot rotate downward, and will move the meshing gear 24 to make it rotate. The meshing gear 24 meshes with the meshing gear 24 of the same group to make it rotate. At this time, the angle between the hinged connecting rod 242 and the gear connecting rod 241 is no longer 180 degrees. The secondary downward pressure on the shell 23 will cause the hinged connecting rod 242 and the gear connecting rod 241 to bend, so as to no longer block the hinged connecting rod 242 and the gear connecting rod 241 from rising. This realizes that the driving cylinder 11 first uses the correction vibration mechanism 3 that can slide up and down to adapt to the complete contour of the steel structure surface in the process of driving the correction process mechanism 2 to descend, and uses the secondary downward pressure plate 212 to press the shell 23 again for the second time, and corrects the raised part of the steel structure surface from high to low to the horizontal, and after the correction is completed, uses the hinged connecting rod 242 and the gear connecting rod 241 to lock the current state to prevent rebound.

[0022] There are two lifting platforms 21, and the two lifting platforms 21 are symmetrically distributed with the central axis of the device shell 1 as the symmetry axis. The downward pressure limit column 221 penetrates the secondary downward pressure shell 23 and is slidably connected to its inner wall. The bottom surface of the secondary downward pressure plate 212 is slidably connected to the top surface of the secondary downward pressure shell 23. The meshing gears 24 are meshed with each other in groups of two. The gear connecting rods 241 and the hinged connecting rods 242 are grouped in groups of two, and the inner surface of each connecting base 243 is hingedly connected to two hinged connecting rods 242. The connecting base 243 is fixedly connected to the top surface of the secondary downward pressure shell 23, and the one-way rotating teeth 2442 are meshed with the meshing gears 24 to correct the sliding grooves 22. 2 are evenly distributed on the outer surface of the driven lifting platform 22. The lifting platform 21 drives the middle driven lifting platform 22 to move up and down on both sides, disperses the force and increases the downward pressure effect. The downward pressure limit column 221 limits the moving path of the secondary downward pressure shell 23 so that it can only move vertically. The secondary downward pressure plate 212 is used to press the secondary downward pressure shell 23 down after the lifting platform 21 stops to correct the surface of the steel structure from high to low. The meshing gear 24, the gear connecting rod 241 and the hinged connecting rod 242 form a group of two each. Each group supports a length of the secondary downward pressure shell 23 when pressing down to prevent the strength of the middle downward pressure from being insufficient and maintain the height of the secondary downward pressure shell 23 and the correction vibration mechanism 3.

[0023] The vibration correction mechanism 3 includes a vertical movable rod 31, the vertical movable rod 31 is slidably connected to the inner surface of the driven lifting platform 22, the outer surface of the vertical movable rod 31 is rotatably connected to a rotating mounting column 32, the outer surface of the rotating mounting column 32 is fixedly connected to a friction wheel 321, driving the outer surface of the rotating mounting column 32 to be rotatably connected to a vibration connecting rod 322, the bottom surface of the vertical movable rod 31 is slidably connected to a correction contact seat 323, the inner surface of the correction contact seat 323 is fixedly connected to a buffer spring 324, the outer surface of the device housing 1 is fixedly connected to a rack mounting frame 33, and the outer surface of the rack mounting frame 33 is fixedly connected to A fixed rack 331 is connected, and a driven gear 332 is meshed on the outer surface of the fixed rack 331. A track mounting column 333 is fixedly connected to the outer surface of the driven gear 332. A friction track 334 is sleeved on the outer surface of the track mounting column 333. Through the setting of the correction vibration mechanism 3, during use, each vertical movable rod 31 can be independently lifted and lowered in the driven lifting platform 22, so that the correction contact seat 323 in contact with the steel structure adapts to the surface contour of the steel structure. When the adaptation is completed, the secondary downward pressing shell 23 presses down the rotating mounting column 32 on the surface of the vertical movable rod 31, and presses down the rotating mounting column 32 from high to low in sequence. Until all the rotating mounting columns 32 are at the same height, since the steel structure surfaces in different areas are all wrapped to prevent the steel structure surface from rising when pressing down, during the descent of the lifting platform 21, the driven gear 332 on the secondary pressing shell 23 will mesh with the fixed rack 331 to convert the direct motion into rotation, and the driven gear 332 drives the track mounting column 333 at the bottom to rotate. Multiple track mounting columns 333 are installed inside, and they are connected and rotated synchronously through the friction track 334. In this way, the friction track 334 will rotate during the descent of the secondary pressing shell 23. When the friction track 334 contacts the friction wheel 32 on the rotating mounting column 32, the friction track 334 will rotate. 1, friction will be used to drive the friction wheel 321 and the rotating mounting column 32 to rotate. The rotating mounting column 32 is connected to the correction contact seat 323 through the vibration connecting rod 322. During the rotation of the rotating mounting column 32, the correction contact seat 323 will be continuously lifted and lowered, and the buffer spring 324 will press the correction contact seat 323 down after it is lifted, so that it moves up and down to generate vibration. In this way, when the rotating mounting column 32 is driven down for the second time by the downward pressure shell 23, the correction contact seat 323 whose bottom is in contact with the surface of the steel structure will continuously vibrate and hit the surface of the steel structure, so that when the raised part of the steel structure is pressed down, the correction effect is improved by a greater force.

At this time, it is similar to a cylindrical cam driving the driven rotating column 43 to rotate, and the driven rotating column 43 drives the active bevel gear 44 to rotate, and the vertical rotation is converted into horizontal rotation through the driven bevel gear 441. The clamping claw mounting plate 46 is rotated by rotating the connecting shaft 45 to achieve a 180-degree flip of the clamped steel structure when the lifting platform 21 is retracted. The clamping claw mounting plate 46 pushes and pulls the push-pull inclined block 462 through the clamping claw cylinder 461, driving the clamping claw connecting blocks 463 on both sides to move away from or approach each other, and driving the synchronous clamping claw 464 to clamp the steel structure when they are close at the same time.The rotating connecting shaft 45 is U-shaped and will not contact the clamping jaw cylinder 461, but still maintains the synchronous rotation of the clamping jaw mounting plate 46 and the driven bevel gear 441.

[0027] In this embodiment, Figure 1 , Figure 2 As shown, the device housing 1 is used to install and protect the remaining components. The driving cylinder 11 at the top presses down and drives the correction process mechanism 2. The base support cylinder 123 changes the height of the support correction base 122 by pushing and pulling the base support wedge 1231 to adapt to steel structures of different sizes. In this embodiment, Figure 3 As shown, the driving cylinder 11 drives the lifting platform 21 to move up and down. While moving downward, the driven lifting platform 22 can slide on the platform sliding column 211, and the secondary pressing plate 212 is used to press down the secondary pressing shell 23; In this embodiment, Figure 4 , Figure 5 As shown, during the process of the secondary pressing shell 23 pressing down, the hinged connecting rod 242 and the gear connecting rod 241 are in line, self-locking and locking the current height of the secondary pressing shell 23. When the lifting platform 21 rises, the one-way rotating tooth 2442 cannot rotate downward, and will move the meshing gear 24 to rotate, and the meshing gear 24 meshes with the meshing gear 24 of the same group to rotate; In this embodiment, Figure 6 , Figure 7As shown, each vertical movable rod 31 can be independently lifted and lowered in the driven lifting platform 22, so that the correction contact seat 323 in contact with the steel structure adapts to the surface contour of the steel structure. During the descent process, the lifting platform 21 presses down the rotating mounting columns 32 from high to low in sequence until all the rotating mounting columns 32 are at the same height, and the driven gear 332 on the secondary pressing housing 23 will mesh with the fixed rack 331 to convert the direct motion into rotation. In this embodiment, Figure 8 , Fig. 9 As shown, the friction track 334 contacts the friction wheel 321 on the rotating mounting column 32, and through the vibration connecting rod 322, during the rotation of the rotating mounting column 32, the correction contact seat 323 is continuously moved up and down to generate vibration; In this embodiment, Fig.10 As shown, when the lifting platform 21 descends, it drives the vertical connecting arm 41 to descend, so that the active downward pressing column 42 at the bottom of the vertical connecting arm 41 is pressed downward in the driven rotating column 43; In this embodiment, Fig.11 , Fig.12 As shown, the toggle protrusion 421 descends in the vertical area of ​​the rotation path groove 431, and the toggle protrusion 421 pushes out the blocking block 433. When returning, the toggle protrusion 421 rises along the oblique edge, driving the driven rotating column 43 to rotate; In this embodiment, Fig.13 , Fig.14 As shown, the driven rotating column 43 rotates, and the driving bevel gear 44 and the driven bevel gear 441 are used to change the rotation path. The clamping claw mounting plate 46 is rotated by rotating the connecting shaft 45. When the lifting platform 21 is folded, the clamped steel structure is flipped 180 degrees. The clamping claw cylinder 461 pushes and pulls the push-pull inclined block 462, driving the clamping claw connecting blocks 463 on both sides to move away from or approach each other, and driving the synchronous clamping claw 464 to clamp the steel structure when they are close at the same time.

[0028] A method for using a correction device for steel structure processing comprises the following steps: S1. The steel structure to be corrected is placed on the surface of the correction base 122. The clamping jaw cylinder 461 pushes and pulls the push-pull inclined block 462, driving the clamping jaw connecting blocks 463 on both sides to move away from or approach each other, and driving the synchronous clamping jaws 464 to clamp the steel structure when they are close to each other at the same time. S2, start the driving cylinder 11 to drive the lifting platform 21 to descend, drive the vertical movable rod 31 to contact the correction contact seat 323 of the steel structure to adapt to the surface contour of the steel structure. When the adaptation is completed, the secondary downward pressing shell 23 presses down the rotating mounting column 32 on the surface of the vertical movable rod 31, and presses down the rotating mounting column 32 from high to low in sequence until all the rotating mounting columns 32 are at the same height, and the driven gear 332 will mesh with the fixed rack 331 to drive the crawler mounting column 333 to rotate, and the crawler mounting column 333 When the friction track 334 is sleeved and contacts the friction wheel 321 on the rotating mounting column 32, the friction wheel 321 and the rotating mounting column 32 are driven to rotate by friction. The rotating mounting column 32 is connected to the correction contact seat 323 through the vibration connecting rod 322. During the rotation of the rotating mounting column 32, the correction contact seat 323 is continuously lifted and lowered, and the buffer spring 324 presses the correction contact seat 323 down after it is lifted, so that it moves up and down continuously to generate vibration, and continuously vibrates and knocks the surface of the steel structure; S3. In the process of the secondary pressing shell 23 pressing down, the connection between the hinged connecting rod 242 and the gear connecting rod 241 bends in the initial state. As the pressing angle of the secondary pressing shell 23 gradually increases until it reaches 180 degrees, the hinged connecting rod 242 and the gear connecting rod 241 are in line with each other. The force of the steel structure to push up the secondary pressing shell 23 will be parallel to the hinged connecting rod 242 and the gear connecting rod 241. The angle is zero and the hinged connecting rod 242 and the gear connecting rod 241 cannot be bent. When the rotating control plug block 244 descends, the one-way rotating tooth 2442 does not rotate upward. When the lifting platform 21 rises, the one-way rotating tooth 2442 cannot rotate downward, and will move the meshing gear 24 to rotate it. The meshing gear 24 meshes with the meshing gear 24 of the same group to rotate it. The rising of the secondary pressing shell 23 will cause the hinged connecting rod 242 and the gear connecting rod 241 to bend, thereby no longer blocking the hinged connecting rod 242 and the gear connecting rod 241 from rising. S4. When the lifting platform 21 descends, the vertical connecting arm 41 will be driven to descend, so that the active downward pressure column 42 at the bottom of the vertical connecting arm 41 will descend in the vertical area of ​​the rotating path groove 431 on the driven rotating column 43, without playing a flipping role, and the toggle protrusion 421 will push out the blocking block 433 so as not to affect the descent of the toggle protrusion 421 in the vertical area of ​​the rotating path groove 431. When the lifting platform 21 rises, the vertical connecting arm 41 is pulled up and the toggle protrusion 421 will also rise, and will no longer push up the blocking block 433, and can only rise in the inclined area of ​​the rotating path groove 431, driving the driven rotating column 43 to rotate, and using the active bevel gear 44 and the driven bevel gear 441 to change the rotating path, and the clamping claw mounting plate 46 is rotated by the rotating connecting shaft 45, so that the clamped steel structure is flipped 180 degrees when the lifting platform 21 is retracted.
