Description

Technical Field

[0001] This utility model relates to the field of steel structure component manufacturing, and more specifically, to a steel component welding deformation correction device. Background Technology

[0002] Steel structures are typically composed of columns, beams, trusses, and plates made of steel plates and structural steel. These components are joined together by welding, riveting, or bolting to form the main framework of the building. Compared to building structures made of other materials, steel structures offer advantages such as high strength, light weight (lower self-weight under the same load), the ability to construct structures with larger spans, and good seismic performance. However, during the welding process, there is a certain probability that the welded joints of steel structural components may bend, resulting in substandard quality of the rectangular steel structural components. Therefore, a welding deformation correction device for steel structural components is needed to correct these deformations.

[0003] A search revealed a Chinese patent publication number: CN222447784U, which provides a welding deformation correction device for steel structure components. Specifically, it relates to the field of steel structure component manufacturing technology, including a correction component. A limiting component is provided above the correction component. The correction component includes a correction plate. A clamping plate is fixedly installed on the front side of the correction plate. A clamping groove is provided on the top surface of the clamping plate.

[0004] Although the aforementioned patent can straighten the bent parts of steel structure components, the aforementioned steel structure component welding deformation correction device still has the following problems: since a large amount of round steel materials such as steel pipes are usually used in construction materials, the device can only correct rectangular steel components and cannot correct round steel materials, so the device has great limitations.

[0005] Therefore, we made improvements and proposed a steel component welding deformation correction device. Utility Model Content

[0006] The purpose of this invention is to solve the problem that the current device cannot straighten round steel materials, which is a significant limitation.

[0008] As a preferred technical solution of this application, the convenient disassembly device includes a sliding rod, which is slidably connected to the inside of a sliding groove. The sliding rod has an "L" shaped cross-section. A connecting rod is fixedly connected to one side of the sliding rod, and a handle is provided on one side of the connecting rod. A first fixing rod is fixedly connected to the bottom of the sliding rod, and the first fixing rod is inserted into the inside of the first fixing groove.

[0009] As a preferred technical solution of this application, a second tension spring is fixedly connected to one end of the sliding rod near the sliding groove, and the other end of the second tension spring away from the sliding rod is fixedly connected to the inner wall of the sliding groove.

[0010] As a preferred technical solution of this application, the top of the correction base is provided with a first limiting groove, and the rotating block is inserted into the inside of the first limiting groove.

[0011] As a preferred technical solution of this application, the inside of the correction base is provided with a transmission groove, the inside of the transmission groove is connected to the inside of the first limiting groove, and the cross-section of the transmission groove is "I-shaped".

[0012] As a preferred technical solution of this application, the transmission groove is slidably connected to a fixing frame, the fixing frame has an "I" shaped cross section, and a protrusion extending to the outside of the correction base is fixedly connected to the top of the fixing frame. The fixing frame is inserted into the inside of the first fixing groove.

[0013] As a preferred technical solution of this application, a spring is fixedly connected to one end of the fixing frame, and the end of the spring away from the fixing frame is fixedly connected to the inner wall of the transmission groove.

[0014] As a preferred technical solution of this application, the power block has a power groove extending to its outside inside, a movable rod is slidably connected inside the power groove, and a second fixed rod is fixedly connected to the end of the movable rod away from the power groove. The cross-section of the second fixed rod is "L-shaped" and a handle is provided on the second fixed rod.

[0015] As a preferred technical solution of this application, a first tension spring is fixedly connected to the end of the moving rod near the power groove, and the end of the first tension spring away from the moving rod is fixedly connected to the inner wall of the power groove.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] In the scheme of this application:

[0019] 1. By placing the steel pipe inside the arc-shaped groove between the upper and lower straightening plates, the steel pipe can be straightened. When it is necessary to straighten a rectangular steel component, the operator can fix the lower straightening plate to the upper straightening plate. The bottom of the lower straightening plate limits the top of the steel component, which to a certain extent makes the device have a wider range of straightening for the workpiece.

[0020] 2. By sliding the limiting block out of the second limiting groove, the staff can easily replace the upper and lower straightening plates according to the different sizes of steel pipes to adapt to the size of the steel pipes and better correct the steel pipes. This effectively reduces the limitation that the upper and lower straightening plates cannot be used to correct steel pipes of different sizes due to the fixed size of the arc grooves on the upper and lower straightening plates.

[0032] Example 1

[0033] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4The steel component welding deformation straightening equipment includes a straightening base 1, a straightening groove 12 on the top of the straightening base 1, a bracket 2 fixedly connected to the top of the straightening base 1, the bracket 2 having a "U" shaped cross-section, a cylinder mounted on the bracket 2 (the cylinder is an existing structure and will not be described in detail), a limit plate 3 fixedly connected to the output end of the cylinder, a power block 5 fixedly connected to the top of the limit plate 3, a second limit groove 22 on the bottom of the limit plate 3, the second limit groove 22 having a trapezoidal cross-section, and a limit block 8 slidably connected inside the second limit groove 22, the limit block 8 having the same cross-section as... The sample is trapezoidal. A second fixing groove 24 is provided on one side of the limiting block 8. An upper straightening plate 14 is fixedly connected to the bottom of the limiting block 8. A lower straightening plate 15 is provided at the bottom of the upper straightening plate 14. Arc-shaped grooves are provided on opposite sides of the upper straightening plate 14 and the lower straightening plate 15 for straightening the circular steel pipe. Two sets of rotating blocks 11 are rotatably connected to both sides of the lower straightening plate 15. A first fixing groove 18 extending to the outside is provided inside the rotating block 11. Two sets of sliding grooves 20 are provided on both sides of the upper straightening plate 14. A convenient disassembly device is provided inside the sliding groove 20.

[0034] Furthermore, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, the convenient disassembly device includes a sliding rod 7, which is slidably connected to the inside of the sliding groove 20. The sliding rod 7 has an "L" shaped cross-section. A connecting rod 9 is fixedly connected to one side of the sliding rod 7, and a handle is provided on one side of the connecting rod 9. A first fixing rod 10 is fixedly connected to the bottom of the sliding rod 7. The first fixing rod 10 is inserted into the inside of the first fixing groove 18. A second tension spring 21 is fixedly connected to the end of the sliding rod 7 near the sliding groove 20. The end of the second tension spring 21 away from the sliding rod 7 is fixedly connected to the inner wall of the sliding groove 20. By sliding the sliding rod 7, the second tension spring 21 can be stretched and reset.

[0035] By pulling the handle on the connecting rod 9, the worker can slide the sliding rod 7, stretching the second tension spring 21. The sliding rod 7 drives the first fixing rod 10 to slide out of the first fixing groove 18, releasing the fixation of the upper straightening plate 14 and the lower straightening plate 15. By releasing the fixation of the upper straightening plate 14 and the lower straightening plate 15, the worker can easily place the lower straightening plate 15 inside the straightening groove 12, and then place the steel pipe inside the arc-shaped groove on the lower straightening plate 15 to straighten the steel pipe. At the same time, by disassembling the lower straightening plate 15, damaged lower straightening plates 15 can be repaired and replaced in a timely manner.

[0036] Example 2

[0037] The steel component welding deformation correction equipment provided in Example 1 has been further optimized, specifically, as follows: Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, the top of the correction base 1 is provided with multiple first limiting grooves 13. The rotating block 11 is inserted into the interior of the first limiting groove 13. The interior of the correction base 1 is provided with a transmission groove 16, which communicates with the interior of the first limiting groove 13. The cross-section of the transmission groove 16 is "I-shaped". A fixing frame 17 is slidably connected inside the transmission groove 16. The cross-section of the fixing frame 17 is "I-shaped". A protrusion extending to the outside of the correction base 1 is fixedly connected to the top of the fixing frame 17. The fixing frame 17 is inserted into the interior of the first fixing groove 18. Two symmetrical springs 26 are fixedly connected to one end of the fixing frame 17. The end of the spring 26 away from the fixing frame 17 is fixedly connected to the inner wall of the transmission groove 16. By sliding the fixing frame 17, the springs 26 can be compressed and reset.

[0038] The operator rotates the rotating block 11 so that the first fixing groove 18 is located at the bottom. Then, the lower straightening plate 15 is placed inside the straightening groove 12. The first fixing groove 18 slides into the first limiting groove 13 and is inserted. Then, the operator moves the protrusion so that the fixing frame 17 slides. The spring 26 is compressed and the rotating block 11 slides into the bottom of the first limiting groove 13. The operator releases the protrusion, the spring 26 returns to its original position, and the fixing frame 17 slides in the opposite direction and is inserted into the first fixing groove 18, which can fix the lower straightening plate 15. By placing the steel pipe inside the arc-shaped groove between the upper straightening plate 14 and the lower straightening plate 15, the steel pipe can be straightened. When it is necessary to straighten a rectangular steel component, the operator can fix the lower straightening plate 15 to the upper straightening plate 14. The bottom of the lower straightening plate 15 limits the top of the steel component, which to a certain extent makes the device have a wider range of workpiece straightening.

[0039] Furthermore, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, the power block 5 has a power groove 25 extending to its outside. A movable rod 4 is slidably connected inside the power groove 25. A second fixed rod 6 is fixedly connected to the end of the movable rod 4 away from the power groove 25. The cross-section of the second fixed rod 6 is "L-shaped" and a handle is provided on the second fixed rod 6.

[0040] Furthermore, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, a first tension spring 19 is fixedly connected to one end of the moving rod 4 near the power groove 25, and the other end of the first tension spring 19 away from the moving rod 4 is fixedly connected to the inner wall of the power groove 25. By sliding the moving rod 4, the first tension spring 19 can be stretched and reset.

[0041] Furthermore, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, the limiting plate 3 has a connecting groove 23 extending to its outside. The inside of the connecting groove 23 communicates with the inside of the second limiting groove 22. The second fixing rod 6 is slidably connected to the inside of the connecting groove 23, and the second fixing rod 6 is inserted into the inside of the second fixing groove 24.

[0042] By pulling the handle on the second fixed rod 6, the worker can slide the second fixed rod 6 out of the second fixed groove 24. At the same time, the second fixed rod 6 drives the moving rod 4 to slide, and the first tension spring 19 is stretched. Then, the worker can push the upper straightening plate 14 or the lower straightening plate 15, which can make the limiting block 8 slide out of the second limiting groove 22. By sliding the limiting block 8 out of the second limiting groove 22, the worker can easily replace the upper straightening plate 14 and the lower straightening plate 15 according to the size of the steel pipe, so as to adapt to the size of the steel pipe and better straighten the steel pipe. This effectively reduces the limitation that the arc groove size on the upper straightening plate 14 and the lower straightening plate 15 is fixed and cannot straighten steel pipes of different sizes.

[0043] Working principle: For this type of steel component welding deformation correction equipment, the worker first pulls the handle on the second fixed rod 6 to make the second fixed rod 6 slide out of the second fixed groove 24, releasing the limit block 8. Then the worker pushes the upper correction plate 14 or the lower correction plate 15 to make the limit block 8 slide out of the second limit groove 22, which makes it convenient for the worker to disassemble the upper correction plate 14 and the lower correction plate 15 as a whole.

[0044] The worker pulls the handle on the connecting rod 9 to slide the sliding rod 7. The sliding rod 7 drives the first fixing rod 10 to slide out of the first fixing groove 18, releasing the fixing of the upper straightening plate 14 and the lower straightening plate 15. The worker rotates the rotating block 11 so that the first fixing groove 18 is at the bottom. Then, the lower straightening plate 15 is placed inside the straightening groove 12. The first fixing groove 18 slides into the first limiting groove 13 and is inserted. Then, the worker moves the protrusion to make the fixing frame 17 slide. The spring 26 is compressed and the rotating block 11 slides into the bottom of the first limiting groove 13. The worker releases the protrusion, the spring 26 returns to its original position, the fixing frame 17 slides in the opposite direction and is inserted into the first fixing groove 18, which can fix the lower straightening plate 15. Then, the worker places the steel pipe in the arc groove on the lower straightening plate 15 to straighten the steel pipe.
