Abstract

The utility model discloses a T-shaped steel structure machining device which comprises a rack, a straightening roller, a first limiting conveying roller, a second limiting conveying roller, a straightening detection mechanism and a synchronous driving mechanism. A plurality of straightening rollers, first limiting conveying rollers and second limiting conveying rollers are arranged on the two opposite sides of the rack at intervals in the length direction of the rack correspondingly, and the first limiting conveying rollers and the second limiting conveying rollers are sequentially arranged from top to bottom in the vertical direction. Limiting grooves matched with the T-shaped steel are coaxially formed in a roller body of the first limiting conveying roller and a roller body of the second limiting conveying roller in a sunken mode. The device overcomes the defects that in the prior art, a device does not detect the straightened steel plate, whether the T-shaped steel plate meets the straightening threshold value or not cannot be known by naked eyes, and therefore the steel plate meeting the specification cannot be obtained. Therefore, the T-shaped steel structure machining device can detect straightened steel plates so as to screen out T-shaped steel plates which do not meet the straightening specification.

Description

Technical Field

[0001] This utility model relates to the field of steel processing technology, specifically to a T-shaped steel structure processing device. Background Technology

[0002] Steel is a malleable material. During the production process, residual stress exists, which is irregularly distributed. This can cause the produced steel to deform or bend. The steel usually needs to be straightened and aligned before leaving the factory. In the process of cutting H-beams directly into T-beams along the center of the web, the cut T-beams are easily bent and deformed, so the cut T-beams need to be straightened.

[0003] Chinese Patent No. CN211247816U discloses a straightening device for processing T-shaped steel. When straightening steel, the first hydraulic cylinder pushes the pressure plate to hold the bottom sides of the steel, and the second hydraulic cylinder pushes the push block so that the stop block on the other side of the push block holds the sides of the middle wing of the steel, thus straightening the steel. The device has a simple structure and is easy to operate. At the same time, the position of the stop block can be adjusted by pushing it up and down during the straightening operation, so that the stop block and the middle wing of the steel can always be kept in a horizontal state. Therefore, it can straighten steel of different sizes, improve applicability, work efficiency and straightening quality.

[0004] The applicant discovered the following technical problems when implementing the above-mentioned technical solution:

[0005] However, the device does not inspect the straightened steel plate, and it is impossible to determine whether the T-shaped steel plate meets the straightening threshold by visual inspection alone, thus making it impossible to obtain a steel plate that meets the specifications.

[0006] Therefore, providing a T-shaped steel structure processing device that can inspect straightened steel plates to screen out T-shaped steel plates that do not meet the straightening specifications is a problem that this utility model urgently needs to solve. Utility Model Content

[0007] To address the aforementioned technical problems, the purpose of this utility model is to overcome the fact that existing devices do not inspect the straightened steel plates, making it impossible to determine whether the T-shaped steel plates meet the straightening threshold by visual inspection alone, thus failing to obtain steel plates that meet specifications. Therefore, this invention provides a T-shaped steel structure processing device capable of inspecting the straightened steel plates to screen out T-shaped steel plates that do not meet the straightening specifications.

[0008] To achieve the above objectives, this utility model provides a T-shaped steel structure processing device. The device includes: a frame, straightening rollers, a first limiting conveyor roller, a second limiting conveyor roller, a straightening and detection mechanism, and a synchronous drive mechanism. The frame has a plurality of straightening rollers, first limiting conveyor rollers, and second limiting conveyor rollers spaced apart along its length on opposite sides.

The bodies of the first and second limiting conveyor rollers are coaxially recessed with limiting grooves adapted to the T-shaped steel. The synchronous drive mechanism is mounted on the frame to drive each first and second limiting conveyor roller to rotate synchronously. The straightening and testing mechanism is located on one side of the frame for detecting the flatness of the T-shaped steel sidewall. The straightening and testing mechanism includes a first movable frame, a first elastic element, and distance sensors. The first movable frame is horizontally movable towards the T-shaped steel on one side of the frame, and its rod is fitted with the first elastic element. Several limiting and engaging rollers capable of abutting against one side of the T-shaped steel are spaced apart at the end of the first movable frame away from the frame. One end of the first elastic element abuts against or is fixed to the frame, and the other end abuts against or is fixed to the first movable frame. Several distance sensors are located inside the frame, and a Hall element corresponding to each distance sensor is located on the side of the first movable frame closest to the frame.

[0009] Preferably, a plurality of first guide rods are movably provided on one side of the first movable frame, penetrating the side wall of the frame.

[0010] Preferably, the frame is provided with a second movable frame that can be raised and lowered on both sides of the frame. A rotating screw is provided vertically and rotatably threaded through the frame at the middle of the upper surface of the second movable frame, and a second guide rod is provided movably through the frame on both sides of the second movable frame. The second limiting conveying roller is provided horizontally and rotatably on the corresponding second movable frame at both ends.

[0011] Preferably, each of the second guide rods is fitted with a third elastic element, one end of which abuts against or is fixed to the upper surface of the second movable frame, and the other end abuts against or is fixed to the inner side of the frame.

[0012] Preferably, the limiting snap-fit ​​roller is coaxially sleeved with a second elastic element and a limiting ring, the upper end of the second elastic element is fixed to the first movable frame, and the lower end is fixed to the limiting ring.

[0013] Preferably, the synchronous drive mechanism includes: a first synchronous gear, a second synchronous gear, a synchronous drive assembly, and a telescopic frame assembly. The first synchronous gear is coaxially disposed at one end of each second limiting conveyor roller. A second cross shaft is coaxially disposed at one end of each second limiting conveyor roller. A plurality of second synchronous gears meshing with each first synchronous gear are rotatably disposed on one side of the frame. A first cross shaft is coaxially disposed on the side of each second synchronous gear near the second cross shaft. The telescopic frame assembly is hinged at opposite ends to the first cross shaft and the second cross shaft, respectively. The synchronous drive assembly is disposed on the frame and is capable of driving each first synchronous gear to rotate synchronously.

[0014] Preferably, the synchronous drive assembly includes: a drive motor, a synchronous pulley, and a synchronous belt. Each first synchronous gear has a synchronous pulley coaxially arranged on one side. The two ends of the synchronous belt are respectively sleeved on the two synchronous pulleys that are furthest apart. The drive motor is mounted on the frame and can drive the second limiting conveyor roller at one end of the synchronous belt to rotate. The frame is also provided with a number of tensioning pulleys for tensioning the synchronous belt.

[0015] Preferably, the telescopic frame assembly includes: a first telescopic frame and a second telescopic frame.

[0016] According to the above technical solution, the beneficial effects of this utility model compared with the prior art are as follows: This application inserts the T-shaped steel into the limiting groove on the first limiting conveying roller and the second limiting conveying roller, and then starts the synchronous drive mechanism to drive each of the first limiting conveying roller and the second limiting conveying roller to rotate synchronously, so as to convey the T-shaped steel through the straightening roller for straightening. When the T-shaped steel is straightened, one side of it will be engaged with the limiting clamping roller. Then the first limiting conveying roller and the second limiting conveying roller continue to convey the T-shaped steel. During the continued conveying process, if the T-shaped steel is not straightened properly, the first moving frame will compress the first elastic element and move back and forth in the horizontal direction. At this time, the distance measuring sensor will detect the change in the distance of the Hall element, thereby determining whether the T-shaped steel is straightened properly. The limiting clamping roller is rotatably set on the first moving frame, which can convert sliding friction into rolling friction, thereby reducing wear and extending service life. By setting multiple distance measuring sensors and Hall elements, the detection accuracy is improved.

[0029] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments.

[0030] Reference Figures 1-3A T-shaped steel structure processing device includes: a frame 1, straightening rollers 2, first limiting conveying rollers 3, second limiting conveying rollers 4, a straightening and detection mechanism 6, and a synchronous drive mechanism 5. The frame 1 has a plurality of straightening rollers 2, first limiting conveying rollers 3, and second limiting conveying rollers 4 spaced apart along its length on opposite sides. The first limiting conveying rollers 3 and 4 are arranged vertically from top to bottom. The roller bodies of the first and second limiting conveying rollers 3 and 4 are coaxially recessed with limiting grooves 401 adapted to the T-shaped steel. The synchronous drive mechanism 5 is mounted on the frame 1 to drive each first limiting conveying roller 3 and second limiting conveying roller 4 to rotate synchronously. The straightening and detection mechanism 6 is located on one side of the frame 1 for straightening and detecting the T-shaped steel. The flatness of the sidewall of the steel section is inspected; wherein, the straightening and inspection mechanism 6 includes: a first movable frame 601, a first elastic element 602 and a distance sensor 603. The first movable frame 601 is arranged on one side of the frame 1 and can reciprocate horizontally toward the T-shaped steel, and its rod is fitted with the first elastic element 602. A number of limiting and engaging rollers 60101 that can abut against one side of the T-shaped steel are arranged at intervals on the end of the first movable frame 601 away from the frame 1. One end of the first elastic element 602 abuts or is fixed to the frame 1, and the other end abuts or is fixed to the first movable frame 601. A number of distance sensors 603 are arranged on the inner side of the frame 1. A Hall element 60102 corresponding to each distance sensor 603 is arranged on the side of the first movable frame 601 near the frame 1.

[0031] This application involves inserting a T-shaped steel beam into the limiting groove 401 on the first limiting conveying roller 3 and the second limiting conveying roller 4, and then activating the synchronous drive mechanism 5 to drive each of the first limiting conveying roller 3 and the second limiting conveying roller 4 to rotate synchronously, so as to convey the T-shaped steel beam through the straightening roller 2 for straightening. After the T-shaped steel beam is straightened, one side of it will engage with the limiting clamping roller 60101. Then the first limiting conveying roller 3 and the second limiting conveying roller 4 continue to convey the T-shaped steel beam. During the continued conveying process, if the T-shaped steel beam is not straightened properly, the first moving frame 601 will compress the first elastic element 602 and move it back and forth in the horizontal direction. At this time, the distance measuring sensor 603 will detect the change in the distance of the Hall element 60102, thereby determining whether the T-shaped steel beam is straightened properly. The limiting clamping roller 60101 is rotatably set on the first moving frame 601, which can convert sliding friction into rolling friction, thereby reducing wear and extending service life. By setting multiple distance measuring sensors 603 and Hall elements 60102, the detection accuracy is improved.

[0032] Reference Figure 3 A number of first guide rods 60103 are movably provided on one side of the first movable frame 601, penetrating the side wall of the frame 1.

[0033] This application uses this design to ensure that the first moving frame 601 can move horizontally back and forth stably without deviation or jamming.

[0034] Reference Figure 2 The frame 1 is provided with a second movable frame 101 that can be raised and lowered on both sides. A rotating screw 102 is provided vertically and rotatably threaded through the frame 1 at the middle of the upper surface of the second movable frame 101, and a second guide rod 103 is provided movably through the frame 1 on both sides of the second movable frame 101. The second limiting conveying roller 4 is horizontally and rotatably mounted on the corresponding second movable frame 101 at both ends.

[0035] This application adjusts the distance between the second limit conveying roller 4 and the first conveying roller by synchronously rotating the rotating screw 102 on each second moving frame 101 to drive the second moving frame 101 to rise and fall, thereby adapting to T-shaped steel of different thicknesses.

[0036] Reference Figure 2 Each of the second guide rods 103 is fitted with a third elastic element 104. One end of the third elastic element 104 abuts against or is fixed to the upper surface of the second movable frame 101, and the other end abuts against or is fixed to the inner side of the frame 1.

[0037] This application uses this design to ensure that the entire second mobile frame 101 can be raised and lowered stably without deviation or jamming.

[0038] Reference Figure 4 The limiting clamping roller 60101 is coaxially sleeved with a second elastic element 60104 and a limiting ring 60105. The upper end of the second elastic element 60104 is fixed to the first moving frame 601, and the lower end is fixed to the limiting ring 60105.

[0039] This application uses this design to ensure that T-shaped steel of different thicknesses can be held in place by the limiting ring 60105 and the limiting clamping roller 60101.

[0040] Reference Figure 2 and Figure 3The synchronous drive mechanism 5 includes a first synchronous gear 501, a second synchronous gear 502, a synchronous drive assembly 504, and a telescopic frame assembly 503. The first synchronous gear 501 is coaxially disposed at one end of each second limiting conveyor roller 4. A second cross shaft 301 is coaxially disposed at one end of each second limiting conveyor roller 4. A plurality of second synchronous gears 502 meshing with each first synchronous gear 501 are rotatably disposed on one side of the frame 1. A first cross shaft 50201 is coaxially disposed on the side of the second synchronous gear 502 near the second cross shaft 301. The telescopic frame assembly 503 is hinged at opposite ends to the first cross shaft 50201 and the second cross shaft 301, respectively. The synchronous drive assembly 504 is disposed on the frame 1 and can drive each first synchronous gear 501 to rotate synchronously.

[0041] This application activates the synchronous drive assembly 504 to drive each of the first synchronous gears 501 and the second limiting conveyor roller 4 to rotate synchronously, thereby driving the second synchronous gear 502 to rotate synchronously. Then, through the action of the first cross shaft 50201, the second cross shaft 301 and the telescopic frame assembly 503, the first limiting conveyor roller 3 is driven to rotate synchronously. The telescopic frame assembly 503 is telescopic, so when the second limiting conveyor roller 4 is raised and lowered under the drive of the second moving frame 101, the first limiting conveyor roller 3 and the second limiting conveyor roller 4 can also rotate synchronously to convey T-shaped steel.

[0042] Reference Figure 3 and Figure 5 The synchronous drive assembly 504 includes a drive motor 50401, a synchronous pulley 50402, and a synchronous belt 50403. Each first synchronous gear 501 has a synchronous pulley 50402 coaxially arranged on one side. The two ends of the synchronous belt 50403 are respectively sleeved on the two synchronous pulleys 50402 that are furthest apart. The drive motor 50401 is mounted on the frame 1 and can drive the second limiting conveyor roller 4 at one end of the synchronous belt 50403 to rotate. The frame 1 is also provided with a plurality of tensioning pulleys 50404 for tensioning the synchronous belt 50403.

[0043] This application starts the drive motor 50401 to drive each synchronous pulley 50402 and the second limit conveyor roller 4 to rotate synchronously via the synchronous belt 50403. The tensioning wheel 50404 can ensure that the wrap angle between the synchronous belt 50403 and each synchronous pulley 50402 is greater than 120 degrees.

[0044] Reference Figure 6The telescopic frame assembly 503 includes a first telescopic frame 50301 and a second telescopic frame 50302. One end of the first telescopic frame 50301 is hinged to the second cross joint 301, and the other end is provided with a telescopic rod 5030101. The telescopic rod 5030101 has a plurality of spline blocks 5030102 coaxially arranged on its body. One end of the second telescopic frame 50302 is hinged to the first cross joint 50201, and the other end is provided with a spline hole 5030201 adapted to the spline block 5030102. The telescopic rod 5030101 is telescopically arranged in the spline hole 5030201.

[0045] This application uses this design to ensure that the first telescopic frame 50301 and the second telescopic frame 50302 can extend and retract stably, while also ensuring that the second synchronous gear 502 and the first limit conveying roller 3 rotate synchronously.

[0046] In use, the device provided by this utility model involves inserting a T-shaped steel into the limiting groove 401 on the first limiting conveying roller 3 and the second limiting conveying roller 4, and then activating the synchronous drive mechanism 5 to drive each of the first limiting conveying roller 3 and the second limiting conveying roller 4 to rotate synchronously, so as to convey the T-shaped steel through the straightening roller 2 for straightening. After the T-shaped steel is straightened, one side of it will engage with the limiting clamping roller 60101. Then the first limiting conveying roller 3 and the second limiting conveying roller 4 continue to convey the T-shaped steel. During the continued conveying process, if the T-shaped steel is not straightened properly, the first moving frame 601 will compress the first elastic element 602 and move it back and forth in the horizontal direction. At this time, the distance sensor 603 will detect the change in the distance of the Hall element 60102, thereby determining whether the T-shaped steel is straightened properly. The limiting clamping roller 60101 is rotatably set on the first moving frame 601, which can convert sliding friction into rolling friction, thereby reducing wear and extending service life. By setting multiple distance sensors 603 and Hall elements 60102, the detection accuracy is improved.
