Description

Technical Field

[0001] This invention relates to the field of pipe bending machine technology, specifically to a pipe bending machine with adaptive spacing. Background Technology

[0002] Pipe bending machines can be broadly categorized into CNC pipe bending machines, hydraulic pipe bending machines, etc. They are mainly used for pipeline laying and repair in power construction, railway and highway construction, boilers, bridges, ships, furniture, decoration, and other fields. They have advantages such as multiple functions, reasonable structure, and simple operation. In the maintenance of steam turbines in thermal power plants, when laying pipelines on-site, disconnecting and welding at corner bends is cumbersome and carries the risk of leakage. In such cases, pipe bending machines are needed to pre-bend the pipelines. Thermal power plants, also known as coal-fired power plants, are factories that use coal, oil, and natural gas as fuels to produce electricity. Their basic production process involves burning fuel in a boiler to heat water to produce steam, converting the chemical energy of the fuel into heat energy. As the heat energy accumulates, the steam pressure increases, thereby driving the steam turbine to rotate. At this point, the heat energy is converted into mechanical energy, and then the steam turbine drives the generator to rotate, converting the mechanical energy into electrical energy.

[0003] In thermal power plants, steam turbines require steam to operate, which is then transported through pipelines. These pipelines need to be bent during on-site installation and maintenance. Existing bending machines consist of a machine body, power unit, worktable, and bending assembly. During bending, the pipeline is placed on the worktable, and the operator manually adjusts the distance between the limit block and the pipeline. After adjustment, the power unit drives the bending assembly to bend the pipeline. This manual adjustment of the bending spacing and repeated changing of bending tools is cumbersome and inconvenient. Therefore, we propose a pipe bending machine with adaptive bending spacing. Summary of the Invention

[0004] The purpose of this invention is to provide a pipe bending machine with adaptive spacing to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a pipe bending machine with adaptive spacing, comprising a pipe bending machine body, an operating platform, and a pipe bending motor.

[0006] An operating platform is provided on the upper side of the pipe bending machine body. A pipe bending motor is installed inside the pipe bending machine body. A control component is provided at the bottom of the pipe bending motor. An installation plate and a clamping plate are installed on the upper side of the pipe bending machine body via an electric telescopic rod. A first adjustment groove is provided on the inner side of both the clamping plate and the operating platform. An abutment column is provided inside the first adjustment groove. The first adjustment groove and the adjustment column are slidably connected. A rotating disk is provided inside and on the top of the pipe bending machine body.

[0007] Preferably, the middle of both rotating disks is connected to the telescopic adjustment rod at the top of the bending motor, and a second adjustment groove is provided inside the rotating disk, which is inserted into the adjustment column.

[0008] Preferably, an electric adjusting rod is installed on one side of the mounting plate, and a pressure sensor is installed on the side of the electric adjusting rod near the adjusting column. The two rotating disks are slidably connected to the slots opened inside the pipe bending machine body and the clamping plate through sliding limiting layers.

[0009] Preferably, an adjusting motor is installed at one end of the mounting plate. The adjusting motor is connected to a threaded adjusting rod via an output shaft. Both ends of the threaded adjusting rod are rotatably mounted to the mounting plate, and the outer side of the threaded adjusting rod is threadedly connected to a threaded adjusting block.

[0010] Preferably, the upper side of the threaded adjusting block is rotatably connected to the bottom of the clamping plate via a support rod, and an inner insertion rod is threadedly installed on one side of the threaded adjusting block. An inner support mechanism is provided on the side of the inner insertion rod away from the threaded adjusting block.

[0011] Preferably, the inner support mechanism consists of a support motor, an adjusting disc, a guide groove, a connecting column, a support column, a guide layer, an abutment block, and a rubber layer. The inner insertion rod has a support motor installed inside. The top of the support motor is connected to the adjusting disc via a rotating shaft. The adjusting disc is inserted into the connecting column via a guide groove.

[0012] Preferably, the bottom of the connecting column is connected to one end of the support column, the other end of the support column is connected to an abutment block, the outer side of the support column is inserted into the guide layer, and the outer side of the abutment block is connected to a rubber layer.

[0013] Preferably, a brake gear is mounted on the upper side of the regulating motor via a rotating shaft, the outer side of the brake gear is inserted into one end of the telescopic brake rod, and the bottom of the telescopic brake rod is installed with an inner connecting rod.

[0014] Preferably, the tube bending machine body is provided with a heating mechanism, which consists of a heating wire, a shaped heating plate and a heating column.

[0015] Preferably, heating columns are installed inside the abutting columns and adjusting columns, heating wires are installed inside the four abutting blocks, and irregularly shaped heating plates are installed inside the operating platform and the clamping plate.

[0016] Compared with the prior art, the beneficial effects of the present invention are: the electric adjusting rod of this pipe bending machine with adaptive spacing pushes the adjusting column to the side where the pipe is located until the electric adjusting rod can no longer push the pipe, and after the pressure sensor at the top of the electric adjusting rod senses a stable pressure signal, it transmits the signal to the control component to control the electric adjusting rod to stop. This solves the problem of cumbersome operation and inconvenience caused by manually adjusting the bending spacing and repeatedly changing the bending tools.

[0017] 1. This adaptive pipe bending machine has the advantages of multiple functions, reasonable structure, and simple operation. To quickly limit the bending of the pipe, place the pipe on the upper side of the operating platform, start the electric adjusting rod, and the electric adjusting rod will push the adjusting column to the side where the pipe is located until the electric adjusting rod can no longer push the pipe. After the pressure sensor at the top of the electric adjusting rod senses a stable pressure signal, it will transmit the signal to the control component to control the electric adjusting rod to be turned off. At this time, start the electric telescopic rod, which will drive the mounting plate to descend and slightly clamp the upper side of the pipe to prevent the pipe from deviating during the bending process. This adaptive pipe bending machine is equipped with an adaptive spacing structure, which can automatically clamp the pipe and adjust the bending angle according to the pipe size, making it easy to operate.

[0018] 2. This adaptive pipe bending machine is simple and convenient to operate. Existing pipe bending machines do not have an internal support mechanism, which can easily lead to excessive bending of the pipe. By starting the support motor inside the internal support mechanism, the support motor drives the adjusting plate to rotate through the output shaft. During the rotation of the adjusting plate, the connecting column is driven forward through the guide groove, pushing the support column and causing the abutment block at the top of the support column to abut against the inner wall of the pipe. This adaptive pipe bending machine is equipped with an internal support mechanism, which can support the inside of the pipe, reduce the deformation rate during the bending process, and facilitate the bending operation.

[0019] 3. This adaptive pipe bending machine offers excellent bending performance. To enhance the deformation force during pipe bending and prevent breakage, the pipe needs to be preheated during the bending process. This is achieved by activating the heating wires inside the contact block, the shaped heating plates inside the operating platform and clamping plate, and the heating columns inside the contact and adjusting columns to heat the four sides and interior of the pipe. The bending point is further heated by the heating wires inside the contact block. This adaptive pipe bending machine is equipped with a heating mechanism that heats the bending area of ​​the pipe, enhancing its deformation capacity and improving the bending effect.

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Please see Figures 1-4 This invention provides a technical solution: a pipe bending machine with adaptive spacing, comprising a pipe bending machine body 1, an operating platform 2, and a pipe bending motor 3.

[0031] An operating platform 2 is provided on the upper side of the pipe bending machine body 1. A pipe bending motor 3 is installed inside the pipe bending machine body 1. A control component 11 is provided at the bottom of the pipe bending motor 3. An installation plate 41 and a clamping plate 42 are installed on the upper side of the pipe bending machine body 1 via an electric telescopic rod 4. A first adjustment groove 43 is provided on the inner side of both the clamping plate 42 and the operating platform 2. An abutment post 44 is provided inside the first adjustment groove 43. The first adjustment groove 43 is slidably connected to the adjustment post 45. A rotating disk 5 is provided inside and on the top of the pipe bending machine body 1.

[0032] The two rotating disks 5 are connected in the middle to the telescopic adjustment rod 31 at the top of the bending motor 3. The rotating disk 5 has a second adjustment groove 51 inside, which is inserted into the adjustment column 45. An electric adjustment rod 52 is installed on one side of the mounting plate 41. A pressure sensor 53 is installed on the side of the electric adjustment rod 52 near the adjustment column 45. The two rotating disks 5 are slidably connected to the slots opened inside the bending machine body 1 and the clamping plate 42 through the sliding limit layer 54.

[0033] In practice, to quickly limit the bending of the pipeline, the pipeline is placed on the upper side of the operating platform 2, and the electric adjusting rod 52 is activated. The electric adjusting rod 52 pushes the adjusting column 45 to the side where the pipeline is located until the electric adjusting rod 52 can no longer push the pipeline. After the pressure sensor 53 at the top of the electric adjusting rod 52 senses a stable pressure signal, it transmits the signal to the control component 11 to control the electric adjusting rod 52 to be turned off. At this time, the electric telescopic rod 4 is activated. The electric telescopic rod 4 drives the mounting plate 41 to descend and slightly clamp the upper side of the pipeline to prevent the pipeline from shifting during the bending process.

[0034] Start the pipe bending motor 3. The pipe bending motor 3 drives the two rotating disks 5 to rotate through the top drive shaft and telescopic adjustment rod 31. During the rotation of the rotating disks 5, they push the abutment column 44 and adjustment column 45 to one side, thus driving the pipe to bend. After the complete bend, start the pipe bending motor 3 to reverse the direction. The operator can then push the adjustment column 45 back to its original position. The telescopic adjustment rod 31 at the top of the pipe bending motor 3 facilitates the electric telescopic rod 4 to push the clamping plate 42 upward. The sliding limit layer 54 at the bottom of the rotating disk 5 is used to ensure the smooth sliding of the rotating disk 5. This spacing adaptive pipe bending machine has the advantages of multiple functions, reasonable structure, and simple operation. It is equipped with a spacing adaptive structure, which can automatically clamp the pipe and adjust the bending angle according to the pipe size, making operation convenient.

[0035] See Figures 4-7It is known that an adjusting motor 6 is installed at one end of the mounting plate 41. The adjusting motor 6 is connected to the threaded adjusting rod 61 through the output shaft. The two ends of the threaded adjusting rod 61 are rotatably installed with the mounting plate 41. The outer side of the threaded adjusting rod 61 is threadedly connected to the threaded adjusting block 62. The upper side of the threaded adjusting block 62 is rotatably connected to the bottom of the clamping plate 42 through the support rod. An inner insertion rod 63 is threadedly installed on one side of the threaded adjusting block 62. An inner support mechanism 7 is provided on the side of the inner insertion rod 63 away from the threaded adjusting block 62.

[0036] The inner support mechanism 7 consists of a support motor 71, an adjusting disc 72, a guide groove 721, a connecting column 73, a support column 74, a guide layer 75, an abutment block 76, and a rubber layer 77. The support motor 71 is installed inside the inner insertion rod 63. The top of the support motor 71 is connected to the adjusting disc 72 via a rotating shaft. The adjusting disc 72 is inserted into the connecting column 73 via the guide groove 721. The bottom of the connecting column 73 is connected to one end of the support column 74. The other end of the support column 74 is connected to the abutment block 76. The outside of the support column 74 is inserted into the guide layer 75. The outside of the abutment block 76 is connected to the rubber layer 77. A brake gear 8 is installed on the upper side of the adjusting motor 6 via a rotating shaft. The outside of the brake gear 8 is inserted into one end of the telescopic brake rod 81. The bottom of the telescopic brake rod 81 is installed with the inner insertion rod 63.

[0037] In practice, the existing pipe bending mechanism does not have an internal support mechanism, which can easily lead to excessive bending of the pipe. The internal support mechanism 7 is activated by the support motor 71 inside. The support motor 71 drives the adjustment plate 72 to rotate through the output shaft. During the rotation of the adjustment plate 72, the connecting column 73 is driven forward through the guide groove 721 to push the support column 74, so that the abutment block 76 at the top of the support column 74 abuts against the inner wall of the pipe.

[0038] After the contact is completed, the telescopic brake lever 81 is activated. The telescopic brake lever 81 extends forward and engages with the brake gear 8, strengthening the contact effect of the contact block 76. The guide layer 75 on the outside of the support column 74 can guide and limit the movement direction of the support column 74, allowing the support column 74 to move smoothly along the guide layer 75. The contact block 76 is arc-shaped, which can avoid affecting the pipe bending process. The rubber layer 77 is installed on the outside of the contact block 76, which protects the outside of the contact block 76 and the inner wall of the pipe while reserving a certain amount of bending deformation space, which is conducive to the bending process. The inner insertion rod 63 is threadedly connected to the threaded adjustment block 62. The adjustment motor 6 is started, and the threaded adjustment rod 61 is rotated through the rotating shaft to adjust the position of the inner insertion rod 63 according to the pipe size. This self-adaptive pipe bending machine is simple and convenient to operate. It is equipped with an internal support mechanism 7, which can support the inside of the pipe, reduce the deformation rate during the bending process, and facilitate the bending operation.

[0039] See Figure 3 and Figure 6 and Figure 8 It is known that the pipe bending machine body 1 is equipped with a heating mechanism 9, which consists of a heating wire 91, a shaped heating plate 92 and a heating column 93. The heating column 93 is installed inside the abutting column 44 and the adjusting column 45. The heating wire 91 is installed inside the four abutting blocks 76. The shaped heating plate 92 is installed inside the operating platform 2 and the clamping plate 42.

[0040] In practice, to enhance the deformation force during pipe bending and prevent pipe breakage, the pipe needs to be preheated during bending. This involves activating the heating wire 91 inside the abutment block 76, the shaped heating plate 92 inside the operating platform 2 and clamping plate 42, and the heating column 93 inside the abutment column 44 and adjusting column 45 to heat the four sides and interior of the pipe. The bending point is further heated by the heating wire 91 inside the abutment block 76. When heated, the molecular motion inside the pipe increases, thereby enhancing its deformation capacity and improving bending performance. This adaptive pipe bending machine has a good bending effect and is equipped with a heating mechanism 9 to heat the bending area of ​​the pipe, enhancing its deformation capacity and improving the bending effect.

[0041] In summary, when using this adaptive pipe bending machine, the machine body 1 is moved to the work site via the brake casters at the bottom of the machine body 1. The pipe is placed on the upper side of the operating platform 2. The electric adjusting rod 52, electric telescopic rod 4, adjusting motor 6, and support motor 71 are activated by the control component 11 to move the adjusting column 45, clamping plate 42, and inner insertion rod 63 to the appropriate positions, and the inner support mechanism 7 is activated to support the inside of the pipe. When the pressure sensor 53 at the top of the electric adjusting rod 52 senses a stable pressure signal, it transmits the signal to the control component 11 to control the electric adjusting rod 52 to be turned off. The pipe bending motor 3 is activated to drive the two rotating disks 5 to rotate through the top drive shaft and telescopic adjusting rod 31. During the rotation, the abutment column 44 and adjusting column 45 are pushed to one side, causing the pipe to bend. The contents not described in detail in this description are existing technologies known to those skilled in the art.

[0042] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
