Description

TECHNICAL FIELD

[0002] The application relates to an automatic feeding device for drilling, in particular to an aluminum alloy structure bending equipment for bridge construction. BACKGROUND

[0004] In the field of bridge construction, aluminum alloy structures are widely used in decorative components, auxiliary structures and part of load-bearing structures of bridges due to their light weight, high strength, corrosion resistance and other excellent properties. The processing quality of the aluminum alloy structure directly affects the overall performance and aesthetics of the bridge. The bending process, as one of the key links in the processing of the aluminum alloy structure, plays a decisive role in the shape accuracy and structural strength of the final product. The traditional aluminum alloy structure bending equipment and process have many limitations and cannot meet the demand for efficient and accurate processing of aluminum alloy structures in bridge construction. Since a fixed bending die is used, the aluminum alloy structure needs to be manually removed from the equipment after each bending operation, and the position needs to be adjusted before the next bending. This operation method is not only inefficient, but also in large-scale bridge construction, frequent manual intervention can easily lead to processing error accumulation, affecting the overall dimensional accuracy and assembly quality of the aluminum alloy structure. Since there is no continuous bending function, the processing process becomes tedious and time-consuming for some complex aluminum alloy structures that need to be bent multiple times, which cannot meet the requirements of rapid progress of bridge construction. In summary, the existing aluminum alloy structure bending equipment has many deficiencies in conveying and positioning, and cannot meet the demand for efficient, accurate and safe processing of aluminum alloy structures in bridge construction. Therefore, it is urgent and necessary to develop a new type of aluminum alloy structure bending equipment for bridge construction. SUMMARY

[0008] As a further further scheme of the present application: the placing assembly comprises a rotating column and an L-shaped plate, the L-shaped plate is fixed to the outer wall of the top of the workbench, the rotating column is movably connected to the inner wall of the through hole on the surface of the L-shaped plate, a rotating plate is welded to the outer wall of the top of the rotating column, and the slide assembly is installed on the top of the rotating plate.

[0009] As a further further scheme of the present application: the slide assembly comprises two pads and a guide plate, the two pads are fixed to the outer wall of the top of the rotating plate, the guide plate is fixed between the two pads, and a support is movably connected to the outer wall of the guide plate.

[0010] As a further further scheme of the present application: a bidirectional threaded rod is movably connected between the two pads, and the bidirectional threaded rod is threadedly connected with the support.

[0011] As a further further scheme of the present application: a vertical plate is fixed to the outer wall of the top of the workbench, a hydraulic cylinder is fixed to one side of the outer wall of the vertical plate, a rack is fixed to the output end of the hydraulic cylinder through a pin, and a gear meshing with the rack is connected to the circumferential outer wall of the rotating column through a key.

[0012] As a further further scheme of the present application: a vertical rod is fixed to the outer wall of the top of the workbench, a support disc is fixed to the outer wall of the top of the vertical rod, a ratchet ring is movably connected to the top of the support disc, an upper plate is fixed to the outer wall of the top of the ratchet ring, and a placing table is fixed to the outer wall of the top of the upper plate.

[0013] As a further further scheme of the present application: an electric telescopic rod is fixed to the outer wall of the top of the support, and a cutter is fixed to the output end of the electric telescopic rod through a pin.

[0014] As a further further scheme of the present application: an installation block is fixed to the circumferential outer wall of the rotating column, a mounting bracket is welded to the side wall of the installation block, a T-shaped rod is movably connected to the through hole formed in one end of the mounting bracket, and a ratchet tooth cooperating with the ratchet ring is fixed to one end of the T-shaped rod.

[0015] As a further further scheme of the present application: a spring is sleeved to the circumferential outer wall of the T-shaped rod, and the spring is fixed to the inner wall of one side of the T-shaped rod and the inner wall of one side of the mounting bracket.

[0016] As a further further scheme of the present application: a positioning hole is formed in the surface of the placing table, and a conical positioning column cooperating with the positioning hole is fixed to the inner wall of the top of the cutter.

[0017] Compared with the prior art, the present application provides a kind of aluminium alloy structure bending equipment for bridge construction, with the following beneficial effects: 1, by the threaded connection of bidirectional threaded rod and support, and the guiding effect of guide plate, only need to drive bidirectional threaded rod to rotate, the interval distance between the two supports can be easily adjusted, so that it is quickly adapted to different outer diameter of aluminium alloy structure, greatly simplifies the preparation work before feeding.

[0018] 2. By setting the bending roller and the bracket to be rotatably connected, the bending roller can rotate relative to the aluminum alloy structure during the bending process, which effectively reduces the friction between the bending roller and the surface of the aluminum alloy structure and avoids surface scratches and wear caused by friction.

[0019] 3. The rotating placement table design with ratchet teeth and ratchet ring is adopted. After the aluminum alloy structure is cut, the ratchet teeth drive the ratchet ring to rotate in one direction, so that the placement table moves the cut aluminum alloy structure away from the cutter for unloading. This avoids contact between the manual or mechanical parts and the cutter during unloading, reducing the safety risks in the unloading process.

[0020] 4. After the aluminum alloy structure is cut, the conveyor roller is driven by the drive motor to rotate, which can quickly transport the remaining part of the aluminum alloy structure to the bending point for re-bending. At the same time, the placement table can be kept at the unloading position after unloading, so as not to affect the continuous bending processing of the remaining aluminum alloy structure.

[0021] 5. When bending the aluminum alloy structure, the electric telescopic rod drives the tapered positioning pin on the cutter to move down and insert into the positioning hole on the surface of the placement platform, effectively limiting the placement platform in the lateral direction and preventing the placement platform from shaking during the bending process, thereby ensuring the stability of the aluminum alloy structure during bending.

[0033] An aluminum alloy structure bending device for bridge construction, designed to facilitate continuous bending, such as... Figures 1 to 7 As shown, the workbench 1 is rotatably connected to the top of the workbench 1. A placement assembly is mounted on the placement assembly, and two sets of brackets 12 are slidably connected to the slide assembly. A conveying roller 24 is rotatably connected between the top and bottom of the bracket 12. A drive motor 23 is fixed to the outer wall of the top of the bracket 12 by bolts, and the output end of the drive motor 23 is connected to the top of the conveying roller 24 by a coupling. The conveying roller 24 is used to convey the aluminum alloy structure 5. A bracket 3 is fixed to the outer wall of the top of the workbench 1 by bolts, and a bending roller 9 is rotatably connected to the inner wall of the top of the bracket 3. When the aluminum alloy structure 5 needs to be bent, the spacing between the conveying rollers 24 on the two supports 12 is first adjusted to match the outer diameter of the aluminum alloy structure 5. When the conveying rollers 24 and the outer wall of the aluminum alloy structure 5 are in contact, the drive motor 23 drives the conveying rollers 24 to rotate, so that the aluminum alloy structure 5 is conveyed under the action of friction. The aluminum alloy structure 5 is loaded during the movement. In the initial state, the aluminum alloy structure 5 is set on one side of the bending roller 9. When the aluminum alloy structure 5 is conveyed to the set distance, the placement component is rotated along the top of the worktable 1, so that the aluminum alloy structure 5 rotates relative to the bending roller 9. Since the bending roller 9 limits the aluminum alloy structure 5, the aluminum alloy structure 5 bends during the rotation. By setting the bending roller 9 and the support 3 to be rotatably connected, the bending roller 9 rotates relative to the aluminum alloy structure 5 during the bending process, reducing the friction of the bending roller 9 on the surface of the aluminum alloy structure 5.

[0034] The placement assembly includes a rotating column 7 and an L-shaped plate 15. The L-shaped plate 15 is fixed to the top outer wall of the workbench 1 by bolts, and the rotating column 7 is rotatably connected to the inner wall of the through hole opened on the surface of the L-shaped plate 15. A rotating plate 28 is welded to the top outer wall of the rotating column 7, and the slide assembly is installed on the top of the rotating plate 28. The slide assembly comprises two pads 25 and a guide plate 26, the two pads 25 are fixed on the top outer wall of the rotating plate 28 by bolts, the guide plate 26 is fixed between the two pads 25 by bolts, the support 12 is slidingly connected to the outer wall of the guide plate 26, a bidirectional threaded rod 27 is rotatably connected between the two pads 25, and the bidirectional threaded rod 27 is threadedly connected with the support 12; Since the bidirectional threaded rod 27 is provided with forward and reverse threads, when the bidirectional threaded rod 27 is driven to rotate, the two supports 12 move in opposite directions under the guidance of the guide plate 26, so that the spacing distance between the conveying rollers 24 on the two supports 12 can be adjusted.

[0035] The top outer wall of the workbench 1 is fixed with a vertical plate 20 by bolts, one side outer wall of the vertical plate 20 is fixed with a hydraulic cylinder 30 by bolts, an output end of the hydraulic cylinder 30 is fixed with a rack 18 by a pin, and the circumferential outer wall of the rotating column 7 is connected with a gear 8 engaged with the rack 18 by a key; The tapered positioning column 19 can drive the rack 18 to move transversely, the rack 18 drives the gear 8 to rotate in the moving process, and the aluminum alloy structure 5 is bent by the bending roller 9 in the rotating process.

[0036] The top outer wall of the workbench 1 is fixed with a vertical plate 20 by bolts, one side outer wall of the vertical plate 20 is fixed with a hydraulic cylinder 30 by bolts, an output end of the hydraulic cylinder 30 is fixed with a rack 18 by a pin, and the circumferential outer wall of the rotating column 7 is connected with a gear 8 engaged with the rack 18 by a key; The placement table 2 can support the aluminum alloy structure 5 when the aluminum alloy structure 5 is bent.

[0037] The top outer wall of the support 3 is fixed with an electric telescopic rod 4 by bolts, and the output end of the electric telescopic rod 4 is fixed with a cutter 29 by a pin; When the aluminum alloy structure 5 is bent, the cutter 29 is driven to move down by the electric telescopic rod 4, and the cutter 29 cuts off the bent aluminum alloy structure 5 in the moving-down process, since the placement table 2 supports the aluminum alloy structure 5, it is convenient for the cutter 29 to exert pressure on the surface of the aluminum alloy structure 5 after moving down, and the remaining part of the aluminum alloy structure 5 is conveyed by the conveying roller 24 driven by the driving motor 23, so as to be bent again.

[0038] The circumferential outer wall of the rotating column 7 is fixed with a mounting block 17 through screws, and the side wall of the mounting block 17 is welded with a mounting rack 16, and the through hole opened at one end of the mounting rack 16 is slidably connected with a T-shaped rod 21, and the circumferential outer wall of the T-shaped rod 21 is sleeved with a spring 22, and the two ends of the spring 22 are respectively fixed to the inner wall of one side of the T-shaped rod 21 and the inner wall of one side of the mounting rack 16, and the one end of the T-shaped rod 21 is fixed with a ratchet tooth 11 matched with the ratchet ring 13 through screws; When the aluminum alloy structure 5 is cut off, the cut-off part will be left on the placing table 2. In order to facilitate the cutting of the cut-off aluminum alloy structure 5, when the ratchet tooth 11 and the ratchet ring 13 are in the state of mutual engagement, when the hydraulic cylinder 30 drives the rack 18 to move transversely, the rack 18 can drive the rotating column 7 and the gear 8 to rotate, and the rotating column 7 indirectly drives the ratchet tooth 11 to rotate in the process of rotation. Since the ratchet tooth 11 can only drive the ratchet ring 13 to rotate in one direction, when the ratchet tooth 11 drives the ratchet ring 13 to rotate in one direction, it can drive the placing table 2 on which the cut-off aluminum alloy structure 5 is left to rotate. The placing table 2 transports the cut-off aluminum alloy structure 5 in the process of rotation, so as to facilitate the subsequent manual or mechanical removal of the cut-off aluminum alloy structure 5. By setting the placing table 2 as a rotating type, when the cut-off aluminum alloy structure 5 needs to be unloaded, it can be away from the cutter 29, thereby ensuring the safety of personnel in the unloading process; When the ratchet tooth 11 transports the placing table 2 to the unloading position and then reversely rotates, the ratchet tooth 11 cannot drive the ratchet ring 13 to reversely rotate, so that the placing table 2 remains at the unloading position to facilitate subsequent unloading, and the rotating column 7 drives the remaining part of the aluminum alloy structure 5 to return to the bending point position again for bending again.

[0039] The surface of the placing table 2 is provided with a positioning hole 6, and the top inner wall of the cutter 29 is fixed with a conical positioning column 19 matched with the positioning hole 6 through screws; In order to ensure the stability of the placing table 2 during bending of the aluminum alloy structure 5, avoid shaking of the placing table 2, use the electric telescopic rod 4 to drive the conical positioning column 19 to move downward and insert into the positioning hole 6, but keep a certain distance between the cutter 29 and the aluminum alloy structure 5. The conical positioning column 19 and the positioning hole 6 limit the placing table 2 in the transverse direction, thereby ensuring the stability of the aluminum alloy structure 5 during bending.

[0040] Working principle: the interval distance between the conveying rollers 24 on the two supports 12 is adjusted, the two supports 12 are moved in opposite directions under the guidance of the guide plates 26 by rotating the bidirectional threaded rod 27, and the feeding preparation is completed when the conveying rollers 24 and the outer wall of the aluminum alloy structure 5 are mutually attached, the driving motor 23 drives the conveying rollers 24 to rotate, under the action of friction, the aluminum alloy structure 5 is conveyed and moved to realize feeding, the initial state of the aluminum alloy structure 5 is arranged on one side of the bending roller 9, when the aluminum alloy structure 5 is conveyed to the set distance, the hydraulic cylinder 30 drives the rack 18 to move transversely, the rack 18 drives the gear 8 to rotate, the rotating column 7 drives the rotating plate 28 to rotate, and the placing assembly is rotated along the top of the workbench 1, the aluminum alloy structure 5 is rotated relative to the bending roller 9, the aluminum alloy structure 5 is bent during rotation, when the aluminum alloy structure 5 is bent, the electric telescopic rod 4 drives the cutter 29 to move downward, the cutter 29 cuts the aluminum alloy structure 5 during downward movement, when the aluminum alloy structure 5 is cut, the cut part is left on the placing table 2, the hydraulic cylinder 30 drives the rack 18 to move transversely, the rack 18 drives the gear 8 to rotate, the rotating column 7 indirectly drives the ratchet tooth 11 to rotate through the mounting block 17 and the mounting frame 16, the ratchet tooth 11 drives the ratchet ring 13 to rotate in one direction, the placing table 2 where the cut aluminum alloy structure 5 is left is driven to rotate, the cut aluminum alloy structure 5 is conveyed, and it is convenient for subsequent manual or mechanical removal, when the aluminum alloy structure 5 is bent, the electric telescopic rod 4 drives the tapered positioning column 19 to move downward and insert into the positioning hole 6 on the surface of the placing table 2, the placing table 2 is limited in the transverse direction by the tapered positioning column 19 and the positioning hole 6, and the stability of the aluminum alloy structure 5 during bending is ensured.
