Description

Technical Field

[0001] The utility model belongs to the technical field of steel structure columns and beams, in particular to a straightening device used for the production of steel structure columns and beams. Background Art

[0002] Steel structure is a structure made of steel materials and is one of the main types of building structures. The structure is mainly composed of steel beams, steel columns, steel trusses and other components made of steel sections and steel plates, and adopts rust removal and rust prevention processes such as silanization, pure manganese phosphating, water washing and drying, and galvanizing. The components or parts are usually connected by welds, bolts or rivets. Because of its light weight and simple construction, it is widely used in large factories, venues, super high-rise buildings, bridges and other fields. Steel structures are prone to rust. Generally, steel structures need to be rust-free, galvanized or painted, and maintained regularly.

[0003] After searching, a patent number of CN217251730U is found, which is a straightening device for steel structure column and beam production. It specifically discloses: a limit seat is arranged above the fixed seat, and fixed plates are fixedly connected to both sides of the top of the limit seat. A limit screw is arranged inside the fixed plate, and an outer wall of the limit screw is provided with an external thread, and an inner wall of the fixed plate is provided with an internal thread matching the external thread. An adjusting handle is fixedly connected to one side of the limit screw, and the other side of the limit screw is fixedly connected to the limit plate. The adjusting handle is rotated, and under the action of the adjusting handle, the limit screw is driven to move horizontally, thereby changing the limit plate to move toward each other. After the limit plate and the side of the component are aligned, the adjusting handle is continued to be rotated to clamp the component. Although the above-mentioned device can realize the clamping of the bent component, the bent component will extend to different degrees around during the flattening process of the hydraulic cylinder. At this time, the bent component is still in a clamped state, which may cause damage to the clamping component and is not conducive to the flattening of the bent component. Therefore, we propose a straightening device for steel structure column and beam production to solve this problem. Utility Model Content

[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0027] See also Figure 1-3 As shown, the utility model is a straightening device for steel structure column beam production, including a press platform 2 and support feet 1 evenly distributed and installed on the lower end surface of the press platform 2, and also includes:

[0028] The lateral moving module 4 is fixed at the center of the upper end surface of the pressing platform 2, and a driving motor is fixed at one end thereof, and the driving motor can drive the internal screw rod to rotate;

[0029] The moving block 8 is fixed just above the transverse moving module 4, and the moving block 8 is divided into two groups. The moving block 8 can move left and right along the linear direction of the transverse moving module 4, so that the staff can load materials from both sides.

[0030] Support columns 3 are fixed on the upper end surface of the press platform 2 in a rectangular distribution. A top plate 5 is fixed on the upper end surface of the support columns 3. The support columns 3 are used to support the top plate 5.

[0031] The clamping assembly is arranged just above the moving block 8 and is used to clamp the bending member. The clamping assembly includes a placing table 9, a sliding plate 13, a threaded rod 14, a limiting column 15 and a clamping plate 17. The placing table 9 is fixed at the central position of the upper end surface of the moving block 8, the sliding plate 13 is arranged on the left and right sides of the placing table 9, the threaded rod 14 is threadedly connected to the inside of the sliding plate 13, the clamping plate 17 is symmetrically arranged just above the placing table 9, and one end of the threaded rod 14 is rotatably connected to the clamping plate 17, and the limiting column 15 is connected to the clamping plate 17. 15 is fixed on the outside of the clamping plate 17, and the limiting column 15 runs through the inside of the clamping plate 17. A rotating handle 18 is fixed on the end of the threaded rod 14 away from the placement table 9. By rotating the rotating handle 18, the threaded rod 14 can be driven to rotate, and then the clamping plate 17 can be driven to move inward along the linear direction of the limiting column 15. The two groups of clamping plates 17 move towards each other to clamp the intermediate curved member, and the set limiting column 15 can support the clamping plate 17 and prevent the clamping plate 17 from rotating.

[0032] A flattening assembly is fixed at the center of the upper end surface of the top plate 5 and is used to flatten the bent member. The flattening assembly includes a hydraulic cylinder 6 and a pressing plate 7. The hydraulic cylinder 6 is fixed at the center of the upper end surface of the top plate 5. The pressing plate 7 is fixed at the output end of the hydraulic cylinder 6. The cross section of the pressing plate 7 is a perfect circular structure. The hydraulic cylinder 6 can drive the pressing plate 7 to move up and down, thereby flattening the bent member directly below.

[0033] The rebound component is arranged inside the clamping component, and is used to cooperate with the flattening component to flatten the bent member, ensure the rebound of the clamping component, and avoid damage to the clamping component. The rebound component includes a slide bar 10, a linear bearing 11 and a spring 12. The slide bar 10 is symmetrically fixed on the left and right sides of the placement table 9, and the slide bar 10 is penetrated into the inside of the clamping plate 17. The linear bearing 11 is slidably connected to the outside of the slide bar 10, and the linear bearing 11 is fixedly connected to the outside of the clamping plate 17. The linear bearing 11 can guide the slide bar 10 and make the rebound process structure more stable. The spring 12 is sleeved on the outside of the slide bar 10, and one end of the spring 12 is in contact with the linear bearing 11, and the slide bar 10 is symmetrically fixed on the left and right sides of the placement table 9, and the slide bar 10 is penetrated into the inside of the clamping plate 17. The linear bearing 11 is slidably connected to the outside of the slide bar 10, and the linear bearing 11 is fixedly connected to the outside of the clamping plate 17. The linear bearing 11 can guide the slide bar 10 and make the rebound process structure more stable. A mounting plate 16 is fixed to one end of the rod 10 away from the anti-placement table 9, and the inner side of the mounting plate 16 is in contact with one end of the spring 12. The mounting plate 16 limits the spring 12 and prevents the spring 12 from sliding off the slide rod 10. The spring 12 can generate a certain thrust on the sliding plate 13, thereby ensuring that the sliding plate 13 is in contact with the left and right sides of the placement table 9 in the clamping state. When the hydraulic cylinder 6 drives the pressure plate 7 to flatten the bending member, the clamping plate 17 is pushed during the extension of the bending member, and the sliding plate 13 can move oppositely along the linear direction of the slide rod 10. The spring 12 can be deformed, thereby avoiding damage to the clamping component when the bending member is extended, thereby extending its service life.

[0034] Working principle: First, place the press platform 2 horizontally, and the support foot 1 is used to support the press platform 2. The transverse moving module 4 is fixed at the central position of the upper end surface of the press platform 2, and a driving motor is fixed at one end thereof. The driving motor can drive the internal screw rod to rotate. The moving block 8 is fixed directly above the transverse moving module 4, and the moving block 8 is divided into two groups. The moving block 8 can move left and right along the linear direction of the transverse moving module 4, which is convenient for the staff to load materials from both sides.

[0035] When in use, the bent member is placed on the upper end surface of the placing table 9, and the threaded rod 14 can be driven to rotate by turning the rotating handle 18, thereby driving the clamping plate 17 to move inward along the linear direction of the limiting column 15. The two groups of clamping plates 17 move toward each other to clamp the middle bent member, and the limiting column 15 can support the clamping plate 17 and prevent the clamping plate 17 from rotating. The hydraulic cylinder 6 can drive the pressing plate 7 to move up and down, thereby flattening the bent member directly below.

[0036] At this time, the set spring 12 can generate a certain thrust on the sliding plate 13, which can ensure that the sliding plate 13 is fitted on the left and right sides of the placement table 9 in the clamping state. When the hydraulic cylinder 6 drives the pressure plate 7 to flatten the bending member, the clamping plate 17 is pushed during the extension of the bending member. The sliding plate 13 can move in the linear direction of the slide rod 10 and the spring 12 can be deformed, which can avoid damage to the clamping component when the bending member is extended, thereby extending its service life.

[0037] The above are only preferred embodiments of the present invention and do not limit the present invention. Any modification to the technical solutions recorded in the aforementioned embodiments and any equivalent replacement of some of the technical features therein, any modification, equivalent replacement, and improvement made are all within the protection scope of the present invention.
