Description

Technical Field

[0001] This invention relates to the field of rail transit technology, and more specifically to an aluminum profile bending device for rail transit construction. Background Technology

[0002] Lightweighting of rail transit is a crucial measure to reduce carbon emissions, and the properties of aluminum alloys make them an inevitable choice for lightweighting transportation vehicles. Aluminum profiles are widely used in rail transit, for example, to make roofs, floors, luggage racks, doors, and window frames. Some aluminum profiles are bent during processing to create shaped components, such as window frames for vehicles.

[0003] In existing aluminum profile bending machines, before operation, a worker needs to insert a long, straight aluminum profile into the clamping mechanism. The profile moves with the clamping mechanism into the bending mechanism and is bent. After removing the bent profile, the worker inserts another profile into the clamping mechanism. Because this manual, sequential feeding of aluminum profiles is impossible, the automation level of such bending machines is low, severely impacting the bending efficiency. Therefore, we propose an aluminum profile bending device for rail transit construction. Summary of the Invention

A rotating plate is fixed to each of the two cylindrical shafts, and a vertical rod is rotatably mounted on each of the two rotating plates. A common swing plate is fixed to the other end of each of the two vertical rods. Multiple feeding groups are spaced apart at the top of the swing plate. A motor for driving one of the cylindrical shafts to rotate is mounted on the support plate. Each feeding group includes a bracket fixed to the swing plate, with a feeding plate rotatably mounted within the bracket. Multiple tension springs are fixed between the feeding plate and the swing plate. The transmission assembly includes pulleys sleeved and fixed to the two cylindrical shafts, with a transmission belt sleeved between the two pulleys.

[0007] Preferably, the mobile clamping system includes a moving part and a clamping part. The clamping part includes a clamping frame with two openings, and two hydraulic rods are mounted on the clamping frame. A contact plate is fixed to the movable end of each hydraulic rod. Support rods are symmetrically fixed inside the clamping frame, and a rotating shaft is rotatably mounted on each support rod. Gears are symmetrically fitted and fixed on the rotating shaft, and gears mesh with toothed rods fixed to the contact plates. Rotating rods are symmetrically fitted and fixed on the rotating shaft, and a top plate is fixed to the other end of each rotating rod. The moving part includes a moving block slidably mounted on a slide rail. A slide block fixed to the top of the moving block and to the clamping frame is fixed. A screw threaded onto the moving block and rotatably connected to a work cabinet is mounted on the moving block. A motor for driving the screw rotation is mounted on the work cabinet. Two slide grooves are provided on the slide block, and a slide bar slidably mounted on the slide grooves is fixed on the work cabinet.

[0008] Preferably, the bending system includes a cylindrical shell with a notch fixed to a work cabinet, a rotating column rotatably mounted on the cylindrical shell, a bending die fixed on the rotating column, a connecting frame fixed on the rotating column, a housing first fixed on the connecting frame, a sliding block first slidably mounted on the housing first, a support frame fixed on the sliding block first, a clamping plate first fixed on the support frame, a hydraulic rod second for driving the sliding block first installed inside the housing first, a gear ring sleeved and fixed on the rotating column, a gear plate slidably mounted on the gear ring and the work cabinet, and a hydraulic rod first for driving the gear plate installed inside the work cabinet.

[0009] Preferably, the anti-deformation system includes a housing two fixed to the work cabinet, a sliding block two slidably mounted on the housing two, and a hydraulic rod three for driving the sliding block two installed inside the housing two. A support frame is fixed on the sliding block two, a sliding plate is slidably mounted inside the support frame, a clamping plate two is fixed on the sliding plate, and an electric push rod one for driving the sliding plate is installed inside the support frame.

[0010] Preferably, the work cabinet is provided with a top support, which includes an electric push rod II installed on the work cabinet, and a guide roller is installed on the movable end of the electric push rod II.

[0011] Preferably, the work cabinet is further provided with an alignment system, which includes a hydraulic rod five installed on the work cabinet, an alignment plate fixed to the movable end of the hydraulic rod five, and a guide rod fixed to the work cabinet slidably installed on the alignment plate.

[0012] (III) This invention provides an aluminum profile bending device for rail transit construction, which has the following beneficial effects:

[0013] 1. By incorporating a feeding system, a bending system, and a moving clamping system, the feeding system is controlled to feed the aluminum profile into the moving clamping system. The moving clamping system clamps the aluminum profile and pushes it into the bending system for bending. After bending, the feeding system can feed the next aluminum profile into the moving clamping system, repeating the above process to achieve automated feeding and bending of aluminum profiles. This process has a high degree of automation and improves the bending efficiency of aluminum profiles.

[0014] 2. By adding a moving clamping system, after the aluminum profile is fed into the clamping frame, the hydraulic rod four is activated, and the abutment plate moves down to clamp the aluminum profile. When the abutment plate moves down, the rotating rod and the top plate on it can be driven to rotate through the transmission of gears and racks until the top plate abuts against the side of the aluminum profile, thus clamping the aluminum profile from multiple directions, improving the clamping effect of the aluminum profile, and the structure is compact and the linkage is also good.

[0015] 3. By adding an anti-deformation system, after clamping the aluminum profile with clamping plate one, before bending, control hydraulic rod three to drive clamping plate two to abut against the aluminum profile. During the bending process of the bending system, start electric push rod one, clamping plate two and aluminum profile move together, and always abut against the straight section of the aluminum profile near the bend, which can prevent the straight section of the aluminum profile from being bent due to force.

[0016] 4. By adding an alignment system, workers can pre-arrange multiple aluminum profiles on the worktable. During the arrangement, one end of the aluminum profile can be directly abutted against the alignment plate. In this way, multiple aluminum profiles can be aligned, reducing the offset error when the aluminum profiles enter the moving clamping system, and thus reducing the error during bending.

[0031] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0032] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0033] Example 1

[0034] like Figures 1-13 As shown, an aluminum profile bending device for rail transit construction includes a work cabinet 1, which has a notch 1a and a slide 1b. The work cabinet 1 is equipped with a movable clamping system 4 for clamping and moving the aluminum profile, a bending system 2 for bending the aluminum profile, an anti-deformation system 3 for preventing the aluminum profile from deforming during bending, and a feeding system 5 for automatically feeding the aluminum profile. In this process, the feeding system 5 controls the aluminum profile to be fed into the moving clamping system 4. The moving clamping system 4 clamps the aluminum profile and moves it towards the bending system 2 until the aluminum profile enters the bending system 2. Before bending, the anti-deformation system 3 controls the aluminum profile to support and constrain it, preventing the straight section of the aluminum profile from bending due to stress. Then, the bending system 2 controls the bending of the aluminum profile. After bending is completed and the aluminum profile is removed, the feeding system 5 can be controlled to feed the next aluminum profile into the moving clamping system 4. The above process is repeated to realize the automated feeding and bending of aluminum profiles. The degree of automation is high, which also improves the bending efficiency of aluminum profiles.

[0035] The feeding system 5 includes a workbench 51, on which a support plate 52 is fixed. Two round shafts 53 are rotatably mounted on the support plate 52. A transmission assembly 54 is provided between the two round shafts 53, and a rotating plate 55 is fixed on each of the two round shafts 53. A vertical rod 56 is rotatably mounted on each of the two rotating plates 55. The other end of each of the two vertical rods 56 is fixed to the same swing plate 58. Multiple feeding groups 59 are spaced apart at the top of the swing plate 58. A motor 57 is mounted on the support plate 52 to drive one of the round shafts 53 to rotate. The operator can arrange multiple aluminum profiles to be bent on the workbench 51 in advance, start the motor 57, and through the transmission assembly 54, drive the two round shafts 53 to rotate simultaneously, which in turn drives the two rotating plates 55 to rotate. Through the transmission of the vertical rod 56, the swing plate 58 moves, which in turn moves the multiple feeding groups 59, thus feeding the aluminum profiles into the mobile clamping system 4.

[0036] The specific movement path of the feeding group 59 is as follows (indicated by...). Figure 5 Taking the orientation determination (up, down, left, right) as an example: The feeding group 59 moves from bottom to top and extends between the spaced aluminum profiles. Then, the feeding group 59 moves from right to left, feeding the aluminum profile that abuts against the leftmost feeding group 59 into the moving clamping system 4. Afterward, the feeding group 59 moves from top to bottom and disengages from the aluminum profile. Subsequently, the feeding group 59 moves from bottom to top and extends between the spaced aluminum profiles again, repeating the above operation. All the aluminum profiles arranged on the worktable 51 will move a distance to the left. In this way, the aluminum profile on the leftmost side will be fed into the moving clamping system 4 by the feeding group 59, realizing automated feeding of aluminum profiles. The degree of automation is high, and the bending efficiency of aluminum profiles is also improved. The feeding group 59 moves according to the above path, and its movement path is roughly circular.

[0037] Specifically, the feeding assembly 59 includes a bracket 591 fixed to the swing plate 58. A feeding plate 592 is mounted inside the bracket 591 with damping rotation. Multiple tension springs 593 are fixed between the feeding plate 592 and the swing plate 58. The top of the feeding plate 592 abuts against the aluminum profile and feeds it into the moving clamping system 4. After the aluminum profile abuts against the clamping frame 421 (here, the feeding plate 592 is located within the opening 421a), the feeding assembly 59 continues to move downwards in an arc. At this time, due to the reaction force of the aluminum profile, the feeding plate 592 flips. During the continued downward movement, the feeding plate 592 can detach from the aluminum profile. Finally, under the tension of the tension springs 593, the feeding plate 592 rotates back and returns to its original position. The notch 1a is provided for the swing plate 58 and the feeding assembly 59 to pass through. The transmission assembly 54 includes pulleys 541 fixed on two round shafts 53, and a transmission belt 542 is sleeved between the two pulleys 541. Under the transmission of the pulleys 541 and the transmission belt 542, the two round shafts 53 can be driven to rotate simultaneously.

[0038] In this embodiment, the movable clamping system 4 includes a movable part 41 and a clamping part 42. The clamping part 42 includes a clamping frame 421. The clamping frame 421 has a first opening 421a and a second opening 421b. Two hydraulic rods 422 are installed on the clamping frame 421. An abutment plate 423 is fixed to the movable end of the hydraulic rod 422. Support rods 424 are symmetrically fixed inside the clamping frame 421. A rotating shaft 425 is rotatably installed on the support rod 424. Gears 426 are symmetrically sleeved and fixed on the rotating shaft 425. A toothed bar 427 fixed to the abutment plate 423 is meshed on the gear 426. A rotating rod 428 is symmetrically sleeved and fixed on the rotating shaft 425. A top plate 429 is fixed to the other end of the rotating rod 428. In this process, the feeding system 5 feeds the aluminum profile into the clamping frame 421, and after the profile abuts against the clamping frame 421, the hydraulic rod 422 is activated, causing the abutment plate 423 to move downwards to clamp the aluminum profile. During the downward movement of the abutment plate 423, the gear 427 moves downwards, which in turn drives the gear 426 meshing with the gear 427 to rotate. This, in turn, drives the rotating shaft 425 fixed to the gear 426 to rotate, which in turn drives the rotating rod 428 and its top plate 429 to rotate until the top plate 429 abuts against the side of the aluminum profile. Figure 8 As shown, it can clamp aluminum profiles from multiple angles, improving the clamping effect of aluminum profiles, and the structure is compact with good linkage.

[0039] In this embodiment, the moving part 41 includes a moving block 412 slidably mounted on the slide rail 1b. A slide base 411, fixed to the top of the moving block 412 and fixed to the clamping frame 421, is specifically provided on the slide base 411. A slide bar slidably mounted on the slide rail is fixed to the work cabinet 1. The slide bar and slide rail are dovetail-shaped, improving the stability of the slide base 411 during movement. A screw 413, rotatably connected to the work cabinet 1, is threaded onto the moving block 412. A motor 414 for driving the screw 413 to rotate is mounted on the work cabinet 1. When the motor 414 is started, it drives the screw 413, fixed to its output end, to rotate, thereby moving the moving block 412 and its slide base 411 towards the bending system 2. This, in turn, moves the clamping frame 421 and its aluminum profile towards the bending system 2, achieving automatic feeding of the aluminum profile.

[0040] In this embodiment, the bending system 2 includes a cylindrical shell 21 with a notch fixed to the work cabinet 1. A rotating column 22 is rotatably mounted on the cylindrical shell 21. A bending die 27 is fixed on the rotating column 22, and a connecting frame 26 is fixed on the rotating column 22. A housing 28 is fixed on the connecting frame 26. A sliding block 29 is slidably mounted on the housing 28. A support frame 211 is fixed on the sliding block 29. A clamping plate 212 is fixed on the support frame 211. A hydraulic rod 210 for driving the sliding block 29 is installed inside the housing 28. A gear ring 23 is sleeved and fixed on the rotating column 22. A toothed plate 24 that is slidably mounted on the work cabinet 1 is engaged on the gear ring 23. A hydraulic rod 25 for driving the toothed plate 24 is installed inside the work cabinet 1. The mobile clamping system 4 feeds the aluminum profile onto the device. When one end of the aluminum profile passes through the bending die 27, the hydraulic rod 510 is activated, which moves the sliding block 29 fixed to its movable end. This moves the support frame 211, which in turn moves the clamping plate 212, pressing the aluminum profile between the clamping plate 212 and the bending die 27. Then, the hydraulic rod 25 is controlled to move the toothed plate 24, which gradually extends out of the work cabinet 1. This causes the toothed ring 23, which meshes with the toothed plate 24, to rotate. Consequently, the rotating column 22 and the bending die 27 rotate (during this process, the clamping plate 212 also rotates), thus bending the aluminum profile.

[0041] Example 2

[0042] refer to Figures 9-10 and Figure 13 The system is basically the same as in Embodiment 1, but with an optimization in that the anti-deformation system 3 includes a housing 31 fixed to the work cabinet 1, a sliding block 33 slidably mounted on the housing 31, and a hydraulic rod 32 for driving the sliding block 33 installed inside the housing 31. A support frame 34 is fixed on the sliding block 33, a sliding plate 35 is slidably mounted inside the support frame 34, a clamping plate 37 is fixed on the sliding plate 35, and an electric push rod 36 for driving the sliding plate 35 is installed inside the support frame 34. When clamping plate 212 clamps the aluminum profile, before bending, hydraulic rod 32 is controlled to move sliding block 33 towards the aluminum profile. This causes support frame 34, sliding plate 35, electric push rod 36 and clamping plate 37 to move towards the aluminum profile until clamping plate 37 abuts against the aluminum profile. During the bending process of bending system 2, electric push rod 36 is activated to move sliding plate 35 and clamping plate 37 on it towards the bending direction, constantly abutting against the straight section of the aluminum profile near the bend, which can prevent the straight section of the aluminum profile from being bent and deformed due to bending.

[0043] Example 3

[0044] refer to Figure 11Similar to Embodiment 1, but with an improvement: the work cabinet 1 is provided with a top support 7, which includes an electric push rod 71 mounted on the work cabinet 1. A guide roller 72 is mounted on the movable end of the electric push rod 71. During the movement of the aluminum profile, the electric push rod 71 is activated, causing the guide roller 72 to move upward until the top of the guide roller 72 contacts the bottom of the aluminum profile, thus providing support for the aluminum profile.

[0045] Example 4

[0046] refer to Figures 1-3 Similar to Embodiment 1, but with an improvement, the work cabinet 1 is further equipped with an alignment system 6. The alignment system 6 includes a hydraulic rod 61 mounted on the work cabinet 1, with an alignment plate 62 fixed to the movable end of the hydraulic rod 61. A guide rod 63, fixed to the work cabinet 1, is slidably mounted on the alignment plate 62. When multiple aluminum profiles are pre-arranged on the worktable 51, one end of each profile can be directly placed against the alignment plate 62 during arrangement. This aligns the multiple profiles, reducing the offset error when they enter the moving clamping system 4, and thus reducing bending errors. Furthermore, controlling the hydraulic rod 61 adjusts the position of the alignment plate 62, making it suitable for aligning aluminum profiles of various lengths and better meeting practical needs.

Those skilled in the art can readily grasp the spirit of the present invention based on the above embodiments and make different extensions and variations, but as long as they do not depart from the spirit of the present invention, they are all within the protection scope of the present invention.
