Description

Technical Field

[0001] This invention relates to steel structure processing technology, and more specifically to a flipping device for steel structure processing. Background Technology

[0002] During the production and processing of steel structures, workpieces such as steel profiles, steel beams, and steel frames usually need to be flipped so that welding, grinding, painting, and inspection can be carried out on each side of the workpiece in sequence.

[0003] Currently, steel structure flipping mainly employs the following methods: First, overhead cranes combined with chain hoisting are used. The steel frame is secured with chains and then lifted by an overhead crane, which drives the chains to rotate and flip the frame. This method is slow, inefficient, and the workpiece swings significantly during hoisting, posing a safety hazard of falling from height. Furthermore, direct contact between the chains and the workpiece surface can easily cause scratches, and collisions and deformations are common during flipping. Second, dedicated flipping machines are used. Most existing flipping machines clamp the short ends of the workpiece and flip it around the long axis, making flipping operations with the long side as the rotation axis relatively convenient. However, in actual production, many processes (such as H-beam flange welding, end face processing, and end drilling) require flipping with the short side as the rotation axis. Existing flipping equipment cannot directly meet the short-side flipping requirements, often necessitating re-clamping and repositioning, which is cumbersome and inefficient. Thirdly, there is the roller conveyor side-turning type, which uses inclined roller conveyors or side-pushing mechanisms to make the workpiece roll on the roller conveyor. It is only suitable for small steel sections with simple cross-sections. For large-sized or complex cross-section steel frames, it is easy to deviate or get stuck during the turning process, and the turning angle is difficult to control precisely.

[0004] In summary, the main technical problems with existing steel structure turning equipment are: turning operations with the short side as the rotation axis are inconvenient; chain hoisting turning methods are slow, unsafe, and prone to damaging workpieces; and dedicated turning machines have limited functionality and cannot meet the needs of turning both long and short sides, resulting in low steel structure processing efficiency and high costs. Therefore, there is an urgent need to develop a turning device for steel structure processing that can easily achieve short-side turning, has high turning efficiency, is safe and reliable, and provides stable clamping.

Detailed Implementation

[0021] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0022] Example: Please see Figures 1-7 A flipping device for steel structure processing is used to flip steel structures. It includes a machine base 1, which is a cuboid frame structure. A bearing part 11 is provided in the middle of the machine base 1 for bearing the steel structure. Roller grooves 12 are symmetrically opened on both sides of the bearing part 11. The length direction of the roller grooves 12 is parallel to the width direction of the machine base 1. Several electrically driven rollers 13 are installed in the roller grooves 12 along their length direction. Two sets of electrically driven rollers 13 are symmetrically distributed on both sides of the rotating seat 22.

[0023] The machine 1 is equipped with a flipping mechanism, which includes a drive unit and a clamping unit. The clamping unit is used to cover and clamp the two ends of the long side of the steel structure.

[0024] An auxiliary unit is provided in the middle of the bearing section 11. The auxiliary unit includes a bearing frame 2 fixedly installed at the bottom of the inner wall of the machine base 1. A support seat 21 is slidably connected to the inner wall of the bearing frame 2 in the vertical direction. A rotating seat 22 is rotatably installed on the top of the support seat 21. The rotating seat 22 is driven by a rotating motor. A lifting cylinder 23 is installed at the bottom of the bearing frame 2. The top of the extension end of the lifting cylinder 23 is fixedly connected to the support seat 21.

[0025] In this embodiment, the drive unit includes a linear guide rail 3 installed at the bottom of the machine base 1. The linear guide rail 3 is arranged along the length of the machine base 1. Two slide blocks 31 are slidably connected to the linear guide rail 3. A bidirectional screw 32 is rotatably mounted on the linear guide rail 3, and the bidirectional screw 32 is arranged along the length of the linear guide rail 3. The two slide blocks 31 are symmetrically threaded to the two ends of the bidirectional screw 32. The bidirectional screw 32 is driven by an adjustable motor. When the bidirectional screw 32 rotates, it can drive the two slide blocks 31 to slide towards or away from each other along the linear guide rail 3, thereby adjusting the distance between the two clamping units to accommodate steel structures of different lengths.

[0026] A support frame 33 is mounted on the top of the machine base 1. A lifting screw 34 is rotatably mounted between the support frame 33 and the slide 31. The lifting screw 34 is externally threaded to a lifting seat 35. The lifting screw 34 is driven by a lifting motor. When the lifting screw 34 rotates, it can drive the lifting seat 35 to move up and down vertically, thereby adjusting the height of the clamping unit to accommodate steel structures of different heights. At the same time, it can also lift the steel structure to a sufficient height during the flipping process, thus ensuring the smooth operation of the flipping process. A flipping seat 36 is rotatably mounted on the opposite side surface of the two lifting seats 35. The flipping seat 36 is driven by a flipping motor and can rotate around a horizontal axis.

[0027] In this embodiment, the clamping unit includes clamping seats 4 fixedly installed on the surface of the flipping seat 36. Vertical guide grooves are symmetrically opened on the left and right sides of the surface of the two clamping seats 4 facing each other. Guide blocks 41 are symmetrically slidably connected at the upper and lower ends inside the vertical guide grooves. The same clamping plate 42 is fixedly installed between the two guide blocks 41 on the same horizontal plane. Anti-slip rubber pads 43 are provided on the surface of the two clamping plates 42 facing each other to increase the clamping friction and prevent the steel structure from slipping during the flipping process.

[0028] The clamping base 4 has an internal cavity that communicates with the vertical guide groove. Synchronous racks 44 are mounted on both the upper and lower guide blocks 41. Synchronous gears 45 are rotatably mounted on the inner wall of the cavity. The two synchronous racks 44 mesh with the sides of the synchronous gears 45. A clamping cylinder 46 is fixedly mounted on the top of the clamping base 4. The bottom of the telescopic end of the clamping cylinder 46 is fixedly connected to the upper clamping plate 42. When the clamping cylinder 46 drives the upper clamping plate 42 to move downwards, the upper guide block 41 drives the upper synchronous rack 44 to move downwards. The upper synchronous rack 44 drives the synchronous gear 45 to rotate, and the synchronous gear 45 drives the lower synchronous rack 44 to move upwards. Thus, the lower clamping plate 42 moves upwards synchronously, achieving synchronous opening and closing of the upper and lower clamping plates 42.

[0029] Two clamping seats 4 have symmetrical guide grooves at both ends of their opposing surfaces. Guide plates are slidably connected to the inner sides of the guide grooves. A clamping plate 47 is fixedly connected between the two guide plates on the same clamping seat 4. Multiple sets of pressure springs 48 are installed at intervals between the side clamping plate 47 and the surface of the clamping seat 4. When the steel structure needs to be clamped, the two side clamping plates 47 contact the side ends of the steel structure and compress the pressure springs 48. The elastic force of the pressure springs 48 causes the side clamping plates 47 to press against the steel structure from the side. Then, the upper and lower clamping plates 42 on the upper and lower sides clamp the upper and lower sides of the steel structure, thereby achieving four-way clamping from top to bottom and left to right.

[0030] In this embodiment, an auxiliary rotation mechanism is provided on the rotating seat 22. The auxiliary rotation mechanism includes a rotating cavity opened inside the rotating seat 22. A drive disk 5 is rotatably installed inside the rotating cavity. The drive disk 5 is driven by an auxiliary motor. The surface of the drive disk 5 is provided with four drive arc grooves 51 equidistantly arranged in annular shape. The surface of the rotating seat 22 is provided with a straight guide groove 52 corresponding to the position of the drive arc grooves 51. The straight guide groove 52 is connected to the rotating cavity. A guide block 53 is slidably connected to the inner wall of the straight guide groove 52. A short column 54 is fixedly connected to the bottom of the guide block 53. The short column 54 is slidably connected to the inner wall of the drive arc groove 51. A positioning block 55 is installed on the top of the guide block 53. The top position of the positioning block 55 is lower than the top surface of the bearing part 11.

[0031] When the auxiliary motor drives the drive disc 5 to rotate, the side wall of the drive arc groove 51 pushes the short column 54 to move along the trajectory of the drive arc groove 51. Since the short column 54 is radially constrained by the linear guide groove 52, the short column 54 drives the guide block 53 to slide radially along the linear guide groove 52, thereby causing the four positioning blocks 55 to extend outward or retract inward synchronously. The synchronous movement of the four positioning blocks 55 can center and position the inner cavity of the steel structure.

[0032] The bearing section 11 has an internal accommodating groove, the inner diameter of which is adapted to the support base 21 and the rotating base 22. When the lifting cylinder 23 retracts, the support base 21 and the rotating base 22 can be housed in the accommodating groove, so that the top surface of the rotating base 22 is not higher than the top surface of the electric drive roller 13, thus not affecting the normal conveying of the steel frame.

[0033] In this embodiment, the top surface of the guide block 53 is provided with an embedded groove 62, the bottom of the inner wall of the embedded groove 62 is provided with a threaded groove 6, the bottom of the positioning block 55 is provided with an embedded block 63, the top of the positioning block 55 is provided with a stud groove that passes through the embedded block 63, a locking stud 61 is inserted into the stud groove, and the bottom end of the locking stud 61 passes through the stud groove and is threadedly connected to the threaded groove 6.

[0034] In use, the steel structure is conveyed to the top of the bearing section 11 by the electric drive roller 13. After reaching the flipping position, the electric drive roller 13 stops operating. Then, according to the length specifications of the steel frame, the bidirectional screw 32 rotates, driving the two slides 31 to move towards or away from each other along the linear guide rail 3, adjusting the distance between the clamping units on both sides to match the length of the steel frame. According to the height specifications of the steel frame, the lifting screw 34 rotates, driving the lifting seat 35 to move vertically, adjusting the height of the clamping unit so that the position of the clamping plate 42 is aligned with the upper and lower surfaces of the steel frame.

[0035] Subsequently, the bidirectional screw 32 continues to rotate, driving the side clamping plates 47 to contact both ends of the steel structure and compressing the pressure spring 48, allowing the side clamping plates 47 to clamp the steel structure from the side. Then, the clamping cylinder 46 is activated, driving the upper clamping plate 42 to move downwards. Through the transmission of the synchronous rack 44 and synchronous gear 45, the lower clamping plate 42 moves upwards synchronously, and the upper and lower clamping plates 42 clamp the steel frame from above and below, achieving four-sided clamping. At this time, the rotation of the flipping seat 36 can drive the steel structure to rotate around its long side as the axis of rotation.

[0036] When it is necessary to rotate the steel structure with the short side as the axis of rotation, it can be rotated with the long side as the axis of rotation first. Then, the steel structure can be rotated horizontally by the rotating seat 22, thereby achieving an equivalent flip with the short side as the axis of rotation, so as to meet the needs of steel structure processing and flipping.

[0037] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
