Description

Technical Field

[0001] This utility model relates to the field of steel structure processing technology, and in particular to a straightening device for steel structure processing. Background Technology

[0002] Steel structures are structures made of steel materials and are one of the main types of building structures. They are primarily composed of steel beams, columns, and trusses made of shaped steel and steel plates. These components are typically connected by welds, bolts, or rivets. Due to their light weight and simple construction, steel structures are widely used in large factories, stadiums, and high-rise buildings. Steel structures are prone to damage and deformation during use, therefore a straightening device is needed to correct any damage or bending.

[0021] See Figures 1-4 This utility model relates to a straightening device for steel structure processing, comprising an L-shaped frame 1, which is movably mounted above a processing table 2. The processing table 2 has two movable holes 3 on its top surface. The processing table 2 is a hollow structure, and both movable holes 3 are connected to the interior of the processing table 2. A PLC controller 4 (Siemens S7-200) is fixed to the front of the processing table 2. Two U-shaped frames 5 are movably mounted inside the processing table 2, each movably mounted within one of the two movable holes 3. Threaded holes are provided on the right side of each U-shaped frame 5. 6. A motor 7 is fixed on the right side of the outer wall of the processing table 2. The output shaft of the motor 7 passes through the processing table 2 and is fixed with a double-acting lead screw 8. The threaded end of the double-acting lead screw 8 is connected to the internal thread of the threaded hole 6. The front and rear sides of the outer walls of the two U-shaped frames 5 are fixed with first cylinders 9. One end of the telescopic rod of the two first cylinders 9 passes through the U-shaped frame 5 and is fixed with a clamping plate 10. A second cylinder 11 is movably arranged below the L-shaped frame 1. One end of the telescopic rod of the second cylinder 11 is provided with a pressure seat 12. The motor 7, the first cylinder 9 and the second cylinder 11 are all electrically connected to the PLC controller 4.

[0022] In this embodiment, the inner walls of the two movable holes 3 are respectively provided with sliding grooves 13 on the front and rear sides, and the inner walls and outer walls of the two U-shaped frames 5 are fixed with sliding blocks 14. The two sliding blocks 14 are respectively slidably arranged in the two sliding grooves 13.

[0023] In this embodiment, the top surface of the processing table 2 is provided with a fixing groove 15. The bottom surface of the fixing groove 15 is fixed with a first guide rail 16. The first guide rail 16 is electrically connected to the PLC controller 4. The top surface of the slider of the first guide rail 16 is fixedly connected to the bottom surface of the L-shaped frame 1. The top surface of the L-shaped frame 1 is fixed with a second guide rail 17. The second guide rail 17 is electrically connected to the PLC controller 4. The bottom surface of the slider of the second guide rail 17 is fixed with a pad 18. The bottom surface of the pad 18 is fixedly connected to the second cylinder 11. One end of the telescopic rod of the second cylinder 11 is fixed with a connecting plate 19. Several buffer springs 20 are fixed between the connecting plate 19 and the pressure seat 12.

[0024] In this embodiment, the top surface of the connecting plate 19 is provided with several limiting holes 21, and limiting posts 22 are slidably inserted into the interior of the several limiting holes 21. The several limiting posts 22 are fixed to the top surface of the pressure seat 12. Several buffer springs 20 are respectively wrapped around the several limiting posts 22. Rubber pads 23 are fixed to the inner sides of the two clamping plates 10. The surface of the rubber pads 23 is provided with anti-slip textures 24.

[0025] In use, the operator first places the steel structure to be straightened on the top surface of the processing table 2. Then, the operator controls the first cylinder 9 on the two U-shaped frames 5 through the PLC controller 4. The telescopic rods of the first cylinder 9 extend synchronously, pushing the two clamping plates 10 closer together, applying clamping force from the front and rear sides of the steel structure simultaneously to achieve a stable fixation. Since the clamping position of the clamping plates 10 can be flexibly adjusted, this device can adapt to steel structures of different sizes. After the fixing operation is completed, the operator again starts the second cylinder 11 through the PLC controller 4. The telescopic rod of the second cylinder 11 drives the pressure seat 1. 2. Move downwards until it is pressed tightly against the steel structure. Straighten the steel structure by applying appropriate pressure. When it is necessary to straighten the end area of ​​the steel structure, the operator only needs to cancel the fixed state of the clamp 10 through the PLC controller 4, and then start the motor 7. The motor 7 drives the bidirectional lead screw 8 to rotate, so that the two U-shaped frames 5 move closer to each other and away from the end area of ​​the steel structure, making room for the end straightening operation. After that, the steel structure is fixed again by the first cylinder 9 and the clamp 10. Finally, the end area of ​​the steel structure is pressed and straightened by the second cylinder 11 and the pressure seat 12.

[0026] By using the L-shaped frame 1, processing table 2, movable hole 3, PLC controller 4, U-shaped frame 5, threaded hole 6, motor 7, double-acting lead screw 8, first cylinder 9, clamping plate 10, second cylinder 11 and pressure seat 12 together, it can not only fix and straighten steel structures of different sizes, but also flexibly meet the straightening requirements of the ends of steel structures, thus improving the flexibility and practicality of the device.

[0027] In use, when the U-shaped frame 5 moves inside the movable hole 3 via the bidirectional lead screw 8, the sliding block 14 slides left and right inside the slide groove 13, which can limit the U-shaped frame 5 and ensure that the U-shaped frame 5 will not shake or deviate during left and right movement, thus improving stability.

[0028] The operator activates the first guide rail 16 via PLC controller 4, enabling the slider on it to move left and right. This causes the L-shaped frame 1, the second cylinder 11, and the pressure seat 12 to move and adjust synchronously left and right. Then, by activating the second guide rail 17, the slider on it can move back and forth, further enabling the pad 18, the second cylinder 11, and the pressure seat 12 to move back and forth for adjustment. This facilitates straightening of different positions on the steel structure and further improves the flexibility of the device. When the second cylinder 11 moves the connecting plate 19 downwards, the pressure seat 12 applies pressure to the steel structure for straightening. At this time, several buffer springs 20 automatically adjust their compression degree according to the pressure changes when the pressure seat 12 contacts the steel structure, playing a buffering role. This buffering effect effectively prevents the pressure seat 12 from applying excessive instantaneous pressure to the steel structure, preventing deformation or damage due to excessive impact. It reduces the impact and damage to the steel structure during straightening, improving the processing quality of the steel structure.

[0029] When the pressure seat 12 presses and straightens the steel structure, the limiting post 22 slides inside the limiting hole 21. The tight fit between the limiting post 22 and the limiting hole 21 effectively prevents the pressure seat 12 from shifting due to the influence of the buffer spring 20 during the straightening process, ensuring uniform distribution of straightening pressure and accuracy of straightening effect. When the clamping plate 10 clamps and fixes the steel structure, the rubber pad 23 fixed on the inner side of the clamping plate 10 will be in close contact with the surface of the steel structure. The rubber pad 23 has good elasticity and softness, which can effectively protect the surface of the steel structure from scratches. At the same time, the anti-slip texture 24 can further increase the friction between the clamping plate 10 and the steel structure, preventing the steel structure from sliding or loosening during the clamping process.
