Description

Technical Field

[0001] The invention relates to the technical field of steel structure processing, and in particular to a bending device for producing assembled steel structures. 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 beams, steel columns, steel trusses and other components made of steel and steel pipes, 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 and other fields.

[0003] During the use of steel structure components, the steel pipes need to be processed first to make them into the desired shape. One of the methods is to bend the steel pipes. When existing assembled steel pipes are bent, the surface of the pipe column is relatively smooth, and the steel pipe is a hollow columnar structure. When it is fixed, the steel pipe is easy to move in the clamping mechanism, resulting in deformation of the steel pipe, affecting the bending effect. In addition, most bending equipment has a complex structure, is difficult to operate, and has a high cost. Summary of the invention

[0004] To achieve the above objectives, the present invention is implemented through the following technical solutions: A bending device for the production of assembled steel structures, comprising: a feeding table, support frames are fixedly installed on both sides of the bottom of the feeding table, and an assembly plate is fixedly installed on one side of the outer surface of the feeding table through the support frame; A guide assembly, which is used for anti-deviation conveying of steel pipes. The guide assembly is fixedly mounted on the top of the feeding platform, and a support assembly is fixedly mounted on one side of the outer surface of the guide assembly; A rocker arm assembly, which is used for adjusting the bending angle of the steel pipe. A positioning frame is rotatably mounted at the bottom of the rocker arm assembly, a motor is fixedly mounted at the bottom of the positioning frame, and the output end of the motor is fixedly connected to the axis of the rocker arm assembly; The positioning frame is fixedly installed on the outer surface of the assembly plate, and the guiding assembly is fixedly installed above the feeding platform through the supporting assembly, and the supporting assembly is arranged above the positioning frame; when the steel structure round tube is bent, the staff inserts the steel pipe into the guiding assembly. At this time, the steel pipe passes through the guiding assembly and extends into the rocker arm assembly, and then the staff starts the motor so that the output end of the motor drives the rocker arm assembly to rotate on the surface of the positioning frame. At this time, the steel pipe passing through the rocker arm assembly is bent as the rocker arm assembly rotates. When the steel pipe is bent, the bending part bulges outward, and the bulging steel pipe and the protective part are squeezed to protect the steel pipe.

[0005] Wherein, the rocker arm assembly includes a rotating frame, the rotating frame is rotatably mounted on the surface of the positioning frame, the top of the rotating frame is rotatably mounted with a shaft disc, the outer surface of the shaft disc is fixedly mounted with a frame block, the top side of the rotating frame is fixedly mounted with an adjustment block, and the surface of the adjustment block is threadedly mounted with a clamping block. The steel pipe passes through the guide assembly and extends to one side of the frame block. At this time, the staff rotates the threaded rod in the adjustment block so that the threaded rod drives the clamping block and the protective member to move, thereby adjusting the position of the protective member and the frame block. At this time, the steel pipe passes through the frame block and the protective member. The staff twists the threaded rod again so that the protective member moves to one side of the frame block to clamp and fix the steel pipe. Then the staff starts the motor so that the output end of the motor drives the rotating frame to rotate. At this time, the rotating frame drives the shaft disc, the frame block and the protective member to twist to bend the steel pipe. When the steel pipe is bent, the protective member is squeezed at the bend of the steel pipe. At this time, the protective member provides buffer protection for the steel pipe.

[0006] Preferably, a protective piece is fixedly mounted on the surface of the clamping block close to the frame block, and the protective piece is movably mounted on the top of the rotating frame through the clamping block.

When the steel pipe runs through the frame block and the protective member, the compression pad is squeezed and deformed, and the compression pad is squeezed to the side of the positioning ring and fits with the positioning ring, thereby protecting the steel pipe and preventing the bending position from being pushed outward with too much force when the hollow steel pipe is bent, causing the steel pipe to be dislocated and deformed.

[0008] Preferably, a compression pad is fixedly mounted on the surface of the positioning ring, the compression pad is extruded and adapted to the steel pipe, an extension pad is fixedly mounted in the middle of the outer surface of the positioning ring, and a side clamping pad is fixedly mounted on the surface of the extension pad.

[0009] Preferably, the guide assembly includes a positioning plate, which is fixedly mounted on the top of the feeding platform, and a slider is slidably mounted on the top of the positioning plate. Two sliders are provided, and a slide bar is slidably mounted between the opposite surfaces of the two sliders. The staff inserts the steel pipe into the through hole, and according to the length of the steel pipe, pushes the support block on the side away from the support assembly to drive the slide bar to slide on the surface of the slide bar, so that the steel pipe is mounted inside the two groups of support blocks, thereby positioning and guiding steel pipes of different lengths.

[0010] Preferably, a positioning block is fixedly mounted on the outer surface of the sliding block, a supporting block is fixedly mounted on the outer surface of the positioning block, a through hole is opened on the surface of the supporting block, and the through hole is sleeved on the surface of the steel pipe.

[0011] Preferably, the support assembly includes a mounting plate, the mounting plate is fixedly mounted on the outer surface of the support block, a circular hole is formed on the surface of the mounting plate, and blocks are fixedly mounted on both sides of the outer surface of the circular hole, and two blocks are provided, and the two blocks are symmetrically arranged with the circular hole as the center. The steel pipe passes through the two groups of through holes and extends between the two groups of receiving parts. At this time, the staff rotates the shaft to drive the extension plate and the receiving part to rotate in the connecting rod to adjust the position angle of the receiving part so that the receiving part fits on both sides of the steel pipe, and limits the steel pipe when the steel pipe is bent and pulled, so as to prevent the steel pipe from passing through the cylindrical steel pipe inside the through hole and rolling in the through hole, causing the steel pipe to deviate when it is bent, affecting the bending effect of the steel pipe.

[0012] Preferably, a clamping rod is fixedly installed inside the clamping block, a circular plate is fixedly installed on the outer surface of the clamping rod, a rotating shaft is rotatably installed at the axis of the circular plate, an extension plate is fixedly installed on the surface of the rotating shaft, a receiving part is fixedly installed on the outer surface of the extension plate, and the receiving part is arranged on both sides of the outer surface of the steel pipe.

[0013] Preferably, the receiving member comprises a mounting block, and the mounting blocks are provided in two groups, both groups of the mounting blocks are fixedly mounted on the outer surface of the extension plate, a round block is fixedly mounted on the outer surface of the mounting block, and an assembly sheet is fixedly mounted on the outer surface of the round block.

A clamping block is fixedly installed between the opposite surfaces of the two groups of elastic columns, and the clamping block is arranged in a curved shape, and the clamping block is frictionally adapted to the surface of the steel pipe. When the steel pipe passes through the clamping block, the curved clamping block fits and covers the surface of the steel pipe. At this time, the clamping block is affected by the shape of the steel pipe and drives the elastic columns on both sides to move. When the clamping block contacts the steel pipe, the elastic column is deformed along with the displacement of the clamping block, so that the clamping blocks arranged in multiple directions can adjust the fitting position according to the surface of the steel pipe.

[0015] The present invention provides a bending device for producing assembled steel structures. It has the following beneficial effects: 1. The bending equipment for the production of prefabricated steel structures extends to one side of the frame block through the steel pipe passing through the guide assembly. At this time, the staff rotates the threaded rod in the adjustment block so that the threaded rod drives the clamping block and the protective part to move, thereby adjusting the position of the protective part and the frame block. At this time, the steel pipe passes through the frame block and the protective part. The staff twists the threaded rod again to make the protective part move to one side of the frame block to clamp and fix the steel pipe. Then the staff starts the motor so that the output end of the motor drives the rotating frame to rotate. At this time, the rotating frame drives the shaft disc, frame block and protective part to twist to bend the steel pipe. When the steel pipe is bent, the protective part is squeezed at the bending part of the steel pipe. At this time, the protective part provides buffering protection for the steel pipe.

[0016] 2. When the bending equipment for the production of prefabricated steel structures passes through the steel pipe between the frame block and the protective part, the extrusion pad is squeezed and deformed. The extrusion pad is squeezed to be concave to the side of the positioning ring and fits with the positioning ring, thereby protecting the steel pipe and preventing the bending position from being pushed outward with excessive force when the hollow steel pipe is bent, causing the steel pipe to be dislocated and deformed.

[0017] 3. The bending equipment for the production of prefabricated steel structures passes the tube through two groups of through holes and extends to between two groups of receiving parts. At this time, the staff rotates the rotating shaft to drive the extension plate and the receiving part to rotate in the clamping rod to adjust the position angle of the receiving part so that the receiving part fits on both sides of the steel pipe. When the steel pipe is bent and pulled, the steel pipe is limited to prevent the steel pipe from passing through the through hole. The cylindrical steel pipe inside the through hole rolls in the through hole, causing the steel pipe to deviate when it is bent, affecting the bending effect of the steel pipe.

[0018] 4. The bending equipment for the production of prefabricated steel structures, when the steel pipe passes through the clamping block, the arc-shaped clamping block fits and covers the surface of the steel pipe. At this time, the clamping block is affected by the shape of the steel pipe and drives the displacement of the elastic columns on both sides. When the clamping block contacts the steel pipe, the elastic columns are deformed as the clamping block is displaced, so that the clamping blocks set in various directions can adjust the fitting position according to the surface of the steel pipe.

[0019] 5. The bending equipment for the production of prefabricated steel structures is used by the staff to insert the steel pipe into the through hole, and push the support block on the side away from the support assembly according to the length of the steel pipe to drive the slider to slide on the surface of the slide rod, so that the steel pipe is installed inside the two groups of support blocks, thereby positioning and guiding steel pipes of different lengths.

[0024] The rocker arm assembly 3 includes a rotating frame 35, which is rotatably mounted on the surface of the positioning frame 1, a shaft disc 31 is rotatably mounted on the top of the rotating frame 35, a frame block 32 is fixedly mounted on the outer surface of the shaft disc 31, an adjustment block 36 is fixedly mounted on the top side of the rotating frame 35, and a clamping block 34 is threadedly mounted on the surface of the adjustment block 36. The steel pipe extends through the guide assembly 5 to one side of the frame block 32. At this time, the staff rotates the threaded rod in the adjustment block 36, so that the threaded rod drives the clamping block 34 and the protective member 33 to move, thereby adjusting the position of the protective member 33 and the frame block 32. At this time, the steel pipe passes through the frame block 32 and the protective member 33. The staff twists the threaded rod again to make the protective member 33 move to one side of the frame block 32 to clamp and fix the steel pipe. Then the staff starts the motor 8 so that the output end of the motor 8 drives the rotating frame 35 to rotate. At this time, the rotating frame 35 drives the shaft disc 31, the frame block 32 and the protective member 33 to twist to bend the steel pipe. When the steel pipe is bent, the protective member 33 is squeezed at the bending point of the steel pipe. At this time, the protective member 33 provides buffering protection for the steel pipe.

[0025] A protective member 33 is fixedly mounted on the surface of the clamping block 34 close to the frame block 32 . The protective member 33 is movably mounted on the top of the rotating frame 35 through the clamping block 34 . Two groups of the protective members 33 are provided, and the two groups of the protective members 33 are adapted to the frame block 32 .

[0026] The protection member 33 includes a positioning groove 334, which is clamped on the outer surface of the clamping block 34. A positioning strip 335 is fixedly installed on the outer surface of the positioning groove 334. Side brackets 331 are fixedly installed on both sides of the outer surface of the positioning strip 335. A positioning ring 337 is fixedly installed on the surface of the side bracket 331. When the steel pipe runs through between the frame block 32 and the protection member 33, the compression pad 336 is squeezed and deformed. The compression pad 336 is squeezed and recessed toward the side of the positioning ring 337, and fits with the positioning ring 337, thereby protecting the steel pipe and preventing the bending position from being pushed outward with excessive force when the hollow steel pipe is bent, causing the steel pipe to be dislocated and deformed.

[0027] An extrusion pad 336 is fixedly installed on the surface of the positioning ring 337 , and the extrusion pad 336 is extruded and adapted to the steel pipe. An extension pad 332 is fixedly installed in the middle of the outer surface of the positioning ring 337 , and a side clamping pad 333 is fixedly installed on the surface of the extension pad 332 .

[0028] The second embodiment is based on the first embodiment. Figures 7 and 8 As shown, the guide assembly 5 includes a positioning plate 56, which is fixedly mounted on the top of the feeding platform 6. A slider 53 is slidably mounted on the top of the positioning plate 56. Two sliders 53 are provided, and a slide bar 54 is slidably mounted between the opposite surfaces of the two sliders 53. The staff inserts the steel pipe into the through hole 52, and pushes the support block 55 on the side away from the support assembly 4 according to the length of the steel pipe to drive the slider 53 to slide on the surface of the slide bar 54, so that the steel pipe is mounted inside the two groups of support blocks 55, thereby positioning and guiding steel pipes of different lengths.

[0029] A positioning block 51 is fixedly mounted on the outer surface of the sliding block 53 , a supporting block 55 is fixedly mounted on the outer surface of the positioning block 51 , a through hole 52 is opened on the surface of the supporting block 55 , and the through hole 52 is sleeved on the surface of the steel pipe.

[0030] The third embodiment is based on the first and second embodiments. Figures 9 and 10 As shown, the support assembly 4 includes a mounting plate 41, which is fixedly mounted on the outer surface of the support block 55. A circular hole 44 is formed on the surface of the mounting plate 41. Blocks 45 are fixedly mounted on both sides of the outer surface of the circular hole 44. Two blocks 45 are provided, and the two blocks 45 are symmetrically arranged with the circular hole 44 as the center. The steel pipe passes through the two groups of through holes 52 and extends between the two groups of receiving parts 43. At this time, the staff rotates the rotating shaft 48 to drive the extension plate 47 and the receiving part 43 to rotate in the clamping rod 42 to adjust the position angle of the receiving part 43, so that the receiving part 43 fits on both sides of the steel pipe, and limits the steel pipe when the steel pipe is bent and twitched, so as to prevent the steel pipe from passing through the cylindrical steel pipe inside the through hole 52 and rolling in the through hole 52, causing the steel pipe to deviate when bending and affecting the bending effect of the steel pipe.

[0031] A clamping rod 42 is fixedly installed inside the clamping block 45, a circular plate 46 is fixedly installed on the outer surface of the clamping rod 42, a rotating shaft 48 is rotatably installed at the axis of the circular plate 46, an extension plate 47 is fixedly installed on the surface of the rotating shaft 48, and a receiving member 43 is fixedly installed on the outer surface of the extension plate 47. The receiving member 43 is arranged on both sides of the outer surface of the steel pipe.

[0032] The receiving member 43 includes a mounting block 431 , and two groups of mounting blocks 431 are provided. Both groups of mounting blocks 431 are fixedly mounted on the outer surface of the extension plate 47 . A round block 432 is fixedly mounted on the outer surface of the mounting block 431 , and an assembly sheet 433 is fixedly mounted on the outer surface of the round block 432 .

[0033] Elastic columns 435 are fixedly installed on both sides of the outer surface of the assembly sheet 433. The elastic columns 435 are provided in two groups. A clamping block 434 is fixedly installed between the opposite surfaces of the two groups of elastic columns 435. The clamping block 434 is arranged in a curved shape, and the clamping block 434 is frictionally adapted to the surface of the steel pipe. When the steel pipe passes through the clamping block 434, the curved clamping block 434 fits and covers the surface of the steel pipe. At this time, the clamping block 434 is affected by the shape of the steel pipe and drives the elastic columns 435 on both sides to move. When the clamping block 434 contacts the steel pipe, the elastic columns 435 are deformed along with the displacement of the clamping block 434, so that the clamping blocks 434 arranged in multiple directions can adjust the fitting position according to the surface of the steel pipe.

[0034] During use, when bending the steel structure round tube, the staff inserts the steel tube into the guide assembly 5. At this time, the steel tube passes through the guide assembly 5 and extends into the rocker arm assembly 3. Then the staff starts the motor 8, so that the output end of the motor 8 drives the rocker arm assembly 3 to rotate on the surface of the positioning frame 1. At this time, the steel tube passing through the rocker arm assembly 3 is bent as the rocker arm assembly 3 rotates. When the steel tube is bent, the bending part bulges outward, and the bulging steel tube and the protective member 33 are squeezed to protect the steel tube.

[0035] The staff inserts the steel pipe into the through hole 52, and pushes the support block 55 away from the support assembly 4 according to the length of the steel pipe to drive the slider 53 to slide on the surface of the slide rod 54, so that the steel pipe is installed inside the two groups of support blocks 55, thereby positioning and guiding steel pipes of different lengths.

[0036] The steel pipe passes through the two groups of through holes 52 and extends between the two groups of receiving parts 43. At this time, the staff rotates the rotating shaft 48 to drive the extension plate 47 and the receiving part 43 to rotate in the clamping rod 42 to adjust the position angle of the receiving part 43 so that the receiving part 43 fits on both sides of the steel pipe and limits the position of the steel pipe when the steel pipe is bent and pulled to prevent the steel pipe from passing through the through hole 52. The cylindrical steel pipe inside the through hole 52 rolls in the through hole 52, causing the steel pipe to deviate when it is bent, affecting the bending effect of the steel pipe.

[0037] When the steel pipe passes through the clamping block 434, the curved clamping block 434 fits and covers the surface of the steel pipe. At this time, the clamping block 434 is affected by the shape of the steel pipe and drives the elastic columns 435 on both sides to move. When the clamping block 434 contacts the steel pipe, the elastic columns 435 are deformed as the clamping block 434 moves, so that the clamping blocks 434 set in various directions can adjust the fitting position according to the surface of the steel pipe.

[0038] The steel pipe extends through the guide assembly 5 to one side of the frame block 32. At this time, the staff rotates the threaded rod in the adjustment block 36 so that the threaded rod drives the clamping block 34 and the protective member 33 to move, thereby adjusting the position of the protective member 33 and the frame block 32. At this time, the steel pipe passes through between the frame block 32 and the protective member 33. The staff twists the threaded rod again to make the protective member 33 move to one side of the frame block 32 to clamp and fix the steel pipe. Then the staff starts the motor 8 so that the output end of the motor 8 drives the rotating frame 35 to rotate. At this time, the rotating frame 35 drives the shaft disc 31, the frame block 32 and the protective member 33 to twist to bend the steel pipe. When the steel pipe is bent, the protective member 33 is squeezed at the bending point of the steel pipe. At this time, the protective member 33 provides buffering protection for the steel pipe.

[0039] When the steel pipe passes through the frame block 32 and the protective member 33, the extrusion pad 336 is squeezed and deformed. The extrusion pad 336 is squeezed to be concave toward the side of the positioning ring 337 and fits with the positioning ring 337, thereby protecting the steel pipe and preventing the bending position from being pushed outward with excessive force when the hollow steel pipe is bent, causing the steel pipe to be dislocated and deformed.
