Description

Technical Field

[0001] This application belongs to the field of bending processing technology, and specifically relates to a rapid pipe bending device. Background Technology

[0002] Pipe bending is an important process in metal processing, widely used in industries such as machinery manufacturing and building decoration. Traditional pipe bending equipment typically uses a simple lifting mechanism to drive bending dies to extrude and shape the pipe. However, this method has the following problems in practical applications:

[0003] Firstly, there is interference between the bending and conveying processes. To simplify the structure, some equipment links the bending and conveying mechanisms, which can cause the conveyor belt to operate unexpectedly during the pipe extrusion and bending stage, resulting in pipe displacement and severely affecting bending accuracy. After bending, the conveyor belt may fail to deliver the pipe smoothly and in a timely manner due to insufficient power or structural limitations, reducing work efficiency.

[0004] Secondly, there is significant frictional damage during the conveying process. In traditional equipment, the conveyor belt is flush with or recessed on the bending platform surface, and the pipes are in direct contact with the platform during conveying. This results in high frictional resistance, which not only easily causes scratches on the pipe surface but may also lead to conveying blockages due to uneven resistance, affecting the continuity of processing.

[0005] In summary, existing pipe bending equipment still has room for improvement in terms of stability, conveying efficiency, and operation. There is an urgent need for a new type of bending equipment that can optimize multiple aspects. Summary of the Invention

[0006] To achieve the above objectives, this application provides a pipe rapid bending device, including a base plate, a fixed column fixedly mounted on the base plate, a connecting seat slidably mounted on the fixed column, a bending mechanism fixedly mounted on the connecting seat, and a top platform fixedly mounted on the end of the fixed column away from the base plate;

[0007] The bending mechanism includes a base with mounting chambers on both sides. Two pulleys are symmetrically and rotatably arranged on the inner wall of the mounting chambers. A connecting groove is opened through the mounting chambers at the top of the base. Two adjusting components are symmetrically arranged on the inner wall of the connecting groove. A conveyor belt is fitted onto the pulleys and the adjusting components. A bending groove is opened on the central axis of the base.

[0008] In one embodiment, the bending mechanism further includes a ratchet, the inner shaft of which is coaxially fixedly mounted on the pulley near the fixed post, and a gear is fixedly sleeved on the outer shaft of the ratchet, the gear meshing with a rack, the rack being fixedly mounted on the side of the fixed post near the base.

[0009] In one embodiment, the adjusting component includes a chute fixedly disposed on the inner wall of the connecting groove, an adjusting roller slidably disposed on the chute, the surface of the roller contacting the conveyor belt, and a compression spring disposed between the adjusting roller and the bottom of the chute.

[0010] In one embodiment, the adjusting slide roller includes a slider, which is slidably disposed within the slide groove, and a rotating roller is rotatably disposed on the slider.

[0011] In one embodiment, the conveyor belt protrudes 2mm-3mm above the connecting groove.

[0012] In one embodiment, a drive mechanism is also installed on the base plate. The drive mechanism includes an adjustment seat and a fixed shaft seat installed on the base plate. An electric telescopic rod is fixedly installed on the adjustment seat. A triangular seat is rotatably installed at the telescopic end of the electric telescopic rod. One end of a second connecting rod is rotatably installed at the end of the triangular seat near the base plate. The other end of the second connecting rod is rotatably connected to the fixed shaft seat.

[0013] One end of the first connecting rod is rotatably mounted on the other end of the triangular seat, and the other end of the first connecting rod is rotatably mounted on the connecting seat.

[0014] In one embodiment, a storage box is also provided on the base plate.

[0015] Compared with the prior art, the beneficial effects of this application are:

[0016] 1. Significantly improved operational stability and safety: The drive mechanism, through the electric telescopic rod, links the triangular seat, the first link, and the second link, causing the connecting seat to rise and fall smoothly along the fixed column, ensuring stable operation of the bending mechanism during the lifting process; at the same time, it avoids burns to workers caused by heat accumulation due to pipe deformation, thus enhancing operational safety.

[0017] 2. Dual optimization of bending accuracy and efficiency: The ratchet and gear rack design ensures that when the bending mechanism moves upward (during the pipe extrusion bending stage), the ratchet is in an unlocked state, the gear rotates without driving the pulley, and the conveyor belt remains stationary, avoiding interference with bending accuracy; when the bending mechanism slides down to reset, the ratchet locks, the gear drives the pulley and conveyor belt to rotate, smoothly delivering the bent pipe, greatly improving work efficiency.

[0018] 3. Smooth conveying process: The adjustment component ensures stable and unbiased operation of the conveyor belt through the dynamic cooperation of the compression spring and the adjustment roller. After bending, the adjustment roller rebounds with the compression spring, lifting the pipe and detaching it from the base surface. At the same time, the conveyor belt (designed to protrude 2mm-3mm from the connecting groove) continues to run, avoiding friction between the pipe and the base and ensuring the smoothness of the conveying process.

Detailed Implementation

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application are described clearly and completely below. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are also within the scope of protection of this application.

[0027] See Figures 1 to 5 As shown, the pipe quick bending equipment provided in this application includes a base plate 1, a fixing column 2 fixedly disposed on the base plate 1, a connecting seat 4 slidably disposed on the fixing column 2, a bending mechanism 5 fixedly disposed on the connecting seat 4, a top platform 6 fixedly disposed at the end of the fixing column 2 away from the base plate 1, and a storage box 7 disposed on the base plate 1.

[0028] When bending the pipe, first place the pipe on the bending mechanism 5. After the pipe is accurately positioned, the drive mechanism 3 drives the preset bending mechanism 5 to slide upward along the fixed column 2. As the bending mechanism 5 moves upward, it works in conjunction with the top platform 6 to squeeze the pipe, gradually bending it to a predetermined angle. Subsequently, the drive mechanism 3 controls the bending mechanism 5 to reset. As the bending mechanism 5 moves downward along the fixed column 2, it smoothly pushes the bent pipe into the storage box 7 for collection.

[0029] The bending mechanism 5 includes a base 51, with mounting chambers 52 on both sides of the base 51. Two pulleys 57 are symmetrically and rotatably arranged on the inner wall of the mounting chambers 52. A connecting groove 53 is formed through the top of the base 51 and the mounting chambers 52. Two adjusting components 55 are symmetrically arranged on the inner wall of the connecting groove 53. A conveyor belt 54 is fitted on the pulleys 57 and the adjusting components 55. A bending groove 510 is formed on the central axis of the base 51.

[0030] During the bending operation, the pipe is placed above the bending groove 510, and the base 51 lifts it up. The base 51 slides upward, bringing the pipe into contact with the top platform 6. The bending groove 510 and the top platform 6 work together to compress the pipe, gradually bending it to a predetermined angle. During the bending process, the adjusting component 55 slides downward under pressure into the connecting groove 53. After the pipe is bent, the base 51 begins to slide downward, and the adjusting component 55 protrudes out of the connecting groove 53, lifting the bent pipe and detaching it from the surface of the base 51. Simultaneously, as the base 51 slides down, the conveyor belt 54 moves the pipe smoothly until it is completely detached from the bending groove 510 and finally falls smoothly into the storage box 7, completing the entire bending operation.

[0031] Optionally, the bending mechanism 5 further includes a ratchet 58, the inner shaft of which is coaxially fixed on the pulley 57 near the fixed post 2, and a gear 56 is fixedly sleeved on the outer shaft of the ratchet 58. The gear 56 meshes with a rack 59, which is fixedly disposed on the side of the fixed post 2 near the base 51.

[0032] In this embodiment, when the base 51 slides upward on the fixed column 2 to bend the pipe, the gear 56 rotates under the drive of the rack 59. At this time, since the ratchet 58 is in an unlocked state, the rotation of the gear 56 cannot drive the pulley 57 to rotate, thereby ensuring that the conveyor belt 54 remains stationary during the pipe bending process, avoiding interference with bending accuracy. When the base 51 returns to its original position and slides down, the ratchet 58 locks, and the gear 56 drives the pulley 57 and the conveyor belt 54 to rotate, ensuring that the pipe is delivered smoothly and improving work efficiency.

[0033] Optionally, the adjusting component 55 includes a slide 551, which is fixedly disposed on the inner wall of the connecting groove 53. An adjusting slide roller 552 is slidably disposed on the slide 551. The surface of the slide roller 552 contacts the conveyor belt 54. A compression spring 553 is disposed between the adjusting slide roller 552 and the bottom of the slide 551.

[0034] In this embodiment, under the action of the compression spring 553, the adjusting roller 552 always maintains close contact with the conveyor belt 54, ensuring stable and unbiased operation of the conveyor belt. When the pipe is bent and the base 51 slides down, the adjusting roller 552 moves upward, and the compression spring 553 gradually rebounds, smoothly lifting the bent pipe and preventing friction with the base 51. At the same time, the conveyor belt 54 continues to operate smoothly, ensuring that the pipe is successfully transferred to the storage box 7. The coordinated operation of each component precisely controls the bending angle and conveying speed, significantly improving the stability and efficiency of the bending operation.

[0035] The adjusting slide roller 552 includes a slider, which is slidably disposed within the slide groove 551, and a rotating roller is rotatably disposed on the slider.

[0036] The conveyor belt 54 protrudes 2mm-3mm from the connecting groove 53. The height difference ensures that the pipe maintains close contact with the conveyor belt 54 during the bending process, which avoids interference with the bending action. At the same time, after the pipe is bent, it ensures that the conveyor belt 54 can quickly and smoothly deliver the pipe, avoiding friction between the pipe and the base 51.

[0037] Optionally, a drive mechanism 3 is also included on the base plate 1. The drive mechanism 3 includes an adjusting seat 31 and a fixed shaft seat 32 mounted on the base plate 1. An electric telescopic rod 33 is fixedly mounted on the adjusting seat 31. A triangular seat 34 is rotatably mounted on the telescopic end of the electric telescopic rod 33. One end of a second connecting rod 36 is rotatably mounted on one end of the triangular seat 34 near the base plate 1. The other end of the second connecting rod 36 is rotatably connected to the fixed shaft seat 32. One end of a first connecting rod 35 is rotatably mounted on the connecting seat 4 at the other end of the triangular seat 34.

[0038] In this embodiment, by adjusting the electric telescopic rod 33, the triangular seat 34 drives the first connecting rod 35 and the second connecting rod 36 to move in tandem, causing the connecting seat 4 to rise and fall smoothly along the fixed column 2. This structure enables the bending mechanism 5 to simultaneously achieve stable transport of the bent pipe while completing the pipe bending operation. This not only significantly improves bending efficiency but also effectively prevents workers from being burned by the heat accumulated due to deformation after the pipe is bent, significantly enhancing the overall safety and reliability of the operation.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
