Description

Technical Field

[0001] This utility model relates to the technical field of bending devices for building steel structures, and in particular to a bending device for building steel structures. Background Technology

[0002] In recent years, the rapid development of my country's large-scale infrastructure construction, energy industry, real estate industry, petrochemical industry and shipbuilding industry has greatly driven the development of my country's heavy machinery manufacturing industry. Among them, steel structure is one of the main building structure types and one of the more common structural forms in modern construction engineering.

[0003] Existing angle steel bending devices for steel structure processing are simple in structure, mostly relying on manual bending, with small bending torque and limited bending angle. Furthermore, manual bending cannot effectively fix the steel structure, resulting in inaccurate angles and poor bending effects, making them unsuitable for installation requirements with certain precision. Therefore, a new steel structure bending device for building was designed.

[0004] This existing patent (publication number: CN220739280U) relates to the field of building technology and discloses a steel structure bending device, including a base. Four support legs are fixedly arranged on the bottom surface of the base and evenly distributed around its perimeter. A bending mechanism is fixedly arranged on the top surface of the base, and a conveying mechanism is arranged on the left side of the base. The bending mechanism includes a bending section and a power section, with the top surface of the power section and the bottom surface of the bending section fixedly connected. The power section includes a motor A, with the top surface of motor A fixedly connected to the bottom surface of the base. This steel structure bending device, through its bending structure and the coordinated operation of motor A and a rotating rod, allows two bending rods to bend the steel plate according to the actual situation. It is convenient to use, simple and quick to operate, and can quickly achieve the desired bending effect, saving time, effort, and labor, without requiring manual assistance in bending.

[0005] To address the aforementioned issues, existing patents offer solutions. However, most existing bending devices for steel structures are not suitable for bending U-shaped steel structures because most existing bending structures are cylindrical. When bending a U-shaped cylinder, they cannot fit snugly against the U-shaped steel, which may cause deformation of the U-shaped steel during bending.

[0006] To address this, a bending device for building steel structures is proposed. Utility Model Content

This is because most existing bending structures are cylindrical, and when bending a U-shaped cylinder, they cannot fit closely to the U-shaped steel, which may cause deformation of the U-shaped steel during bending.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-5 The present invention provides the following technical solution:

[0028] A steel structure bending device for buildings includes a top plate 1, a limit assembly 2 fixedly connected to the top of the top plate 1, a fixing block 3 fixedly connected to the top of the top plate 1, a first electric telescopic rod 4 fixedly connected inside the fixing block 3, a pressing block 5 fixedly connected to the left side of the first electric telescopic rod 4, and a support assembly 6 fixedly connected to the bottom of the top plate 1.

[0029] The limiting component 2 includes a first adjusting block 201, a connecting block 202 fixedly connected to the top of the first adjusting block 201, a second adjusting block 203 fixedly connected to the top of the connecting block 202, adjusting discs 204 threadedly connected to the surfaces of both the first adjusting block 201 and the second adjusting block 203, a frame 205 movably connected to the surface of the connecting block 202, a bearing 206 fixedly connected to the left side of the connecting block 202, a first threaded rod 207 bolted to the inner wall of the bearing 206, and the surface of the first threaded rod 207 threadedly connected to the frame 205.

[0030] In this embodiment: The top plate 1 supports the fixing block 3 and places the U-shaped steel. After the U-shaped steel is engaged with the limiting component 2 via the fixing block 3, the first electric telescopic rod 4, and the pressing block 5, the first electric telescopic rod 4 is activated to adjust the pressing block 5, causing the pressing block 5 to bend the U-shaped steel. The support component 6 allows for height adjustment of the top plate 1 as needed. The top plate 1 is equipped with a first adjusting block 201, a connecting block 202, a second adjusting block 203, two adjusting discs 204, a frame 205, a bearing 206, and a first threaded rod 207. The user first adjusts the height of the U-shaped steel according to the following parameters: The inner diameter of the steel is adjusted, and then the distance between the two adjusting discs 204 on the surfaces of the first adjusting block 201 and the second adjusting block 203 is manually adjusted to fit the shape of the U-shaped steel. Then, the user manually operates the first threaded rod 207 to rotate it. When the first threaded rod 207 rotates, the frame 205 will move on the surface of the connecting block 202. When the first threaded rod 207 moves, it works with the bearing 206 to move the position of the frame 205 while keeping the position of the first threaded rod 207 unchanged. Then, the frame 205 contacts the inner diameter of the U-shaped steel to achieve a fit with the U-shaped steel so that it can be bent.

[0031] Specifically, such as Figure 4 As shown, a sliding groove 7 is provided on the top of the top plate 1. A second threaded rod 8 is rotatably connected to the front side of the inner wall of the sliding groove 7. A sliding block 9 that cooperates with the sliding groove 7 is threadedly connected to the surface of the second threaded rod 8. The first adjusting block 201 is fixedly connected to the top of the sliding block 9.

[0032] Specifically, such as Figure 4 As shown, an adjustment knob 10 is fixedly connected to the rear side of the second threaded rod 8, and an anti-slip block 11 is fixedly connected to the surface of the adjustment knob 10.

[0033] Specifically, such as Figure 1 As shown, a soft pad 12 is fixedly connected to the surface of the frame 205. The soft pad 12 is made of silicone.

[0034] In this embodiment: by setting a sliding groove 7, a second threaded rod 8, a sliding block 9, an adjusting knob 10, and an anti-slip block 11, the user manually contacts the anti-slip block 11, which works in conjunction with the adjusting knob 10. Then, the user manually adjusts the anti-slip block 11, so that the adjusting knob 10 adjusts the second threaded rod 8, and the second threaded rod 8 adjusts the sliding block 9 on the inner wall of the sliding groove 7, so that the sliding block 9 moves and adjusts the position of the limiting component 2, which facilitates the adjustment of the bending angle. By setting a soft pad 12, the problem of U-shaped steel damaging the frame 205 can be reduced.

[0035] Specifically, such as Figure 1 , Figure 4 As shown, a support frame 13 is fixedly connected to the top of the top plate 1, a second electric telescopic rod 14 is fixedly connected inside the support frame 13, and a lower pressure plate 15 is bolted to the bottom of the second electric telescopic rod 14.

[0036] Specifically, such as Figure 5 As shown, a splicing groove 16 is provided on the rear side of the lower pressure plate 15, and a splicing block 17 is snapped into the inside of the splicing groove 16. A limit plate 18 is fixedly connected to the bottom of the splicing block 17.

[0037] In this embodiment: a support frame 13, a second electric telescopic rod 14, a lower pressure plate 15, and a limiting plate 18 are provided. The support frame 13 supports the second electric telescopic rod 14, and the height of the second electric telescopic rod 14 is adjusted to adjust the height of the lower pressure plate 15 to adjust the height of the limiting plate 18, so that the limiting plate 18 contacts the top of the U-shaped steel and limits the top of the U-shaped steel to facilitate bending. A splicing groove 16 and a splicing block 17 are provided, and the splicing block 17 is spliced ​​with the inner wall of the splicing groove 16 to facilitate the disassembly, replacement, and maintenance of the limiting plate 18.

[0038] Specifically, such as Figure 1 , Figure 3 As shown, the support assembly 6 includes a third electric telescopic rod 601, an auxiliary frame 602 is fixedly connected to the bottom of the third electric telescopic rod 601, and four storage racks 603 are fixedly connected to the surface of the auxiliary frame 602.

[0039] Specifically, such as Figure 1 , Figure 3 As shown, extension rods 604 are slidably connected to the inner walls of the four storage racks 603. The four extension rods 604 are fixedly connected to the bottom of the top plate 1. The bottom of the four storage racks 603 is fixedly connected to the bottom plate 605. The bottom of the bottom plate 605 is fixedly connected to the caster wheel 606.

[0040] In this embodiment, a third electric telescopic rod 601, an auxiliary frame 602, four storage racks 603, four extension rods 604, a base plate 605, and casters 606 are provided. The base plate 605 supports the four storage racks 603, and the extension rods 604 inside the four storage racks 603 are all in contact with the bottom of the top plate 1. Subsequently, the user can adjust the height of the third electric telescopic rod 601 on the top of the auxiliary frame 602 to adjust the height of the third electric extension rod relative to the top plate 1. As the height of the top plate 1 is adjusted, the extension rods 604 are adjusted on the inner wall of the storage racks 603, thereby achieving the height adjustment of the top plate 1. This allows users of different heights to easily operate the structure.

[0041] Working principle: In use, firstly, according to the operator's height requirement, activate the third electric telescopic rod 601. Adjust the height of the top plate 1 by sliding the extension rod 604 within the storage rack 603. First, manually rotate the adjusting disc 204 according to the inner diameter of the U-shaped steel to adjust the distance between the first adjusting block 201, the second adjusting block 203, and the frame 205, ensuring they fit the shape of the U-shaped steel. Then, rotate the first threaded rod 207 to move the frame 205 on the surface of the connecting block 202 until the frame 205 is tightly fitted against the inner wall of the U-shaped steel. Finally, manually rotate the adjusting disc... Button 10 drives the sliding block 9 to move laterally in the sliding groove 7 via the second threaded rod 8, adjusting the position of the limiting component 2 to determine the bending point. Then, the second electric telescopic rod 14 is activated, driving the lower pressure plate 15 to descend through the limiting plate 18 connected by the splicing block 17, limiting the top of the U-shaped steel. Finally, the first electric telescopic rod 4 is activated, pushing the extrusion block 5 to apply bending force to the U-shaped steel, completing the bending operation. During the process, the silicone pad 12 on the surface of the frame 205 can reduce the wear on the U-shaped steel, and the bottom universal wheel 606 facilitates the movement and adjustment of the device.

[0042] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model.
