The methods include: The first bending wheel is driven to rise by the first lifting component so that the first bending wheel and the positioning wheel are at the same height. The second bending wheel is driven to descend by the second lifting component so that the upper surface of the second bending wheel is lower than the lower surface of the first bending wheel; Install the aviation pipe onto the pipe support assembly and insert the aviation pipe between the positioning wheel and the first bending wheel; The bending component is driven by the linear drive component to move along the length of the base, thereby driving the positioning wheel and the first bending wheel to move to the preset bending position of the aviation tube. The turntable is driven to rotate by a rotary drive assembly. When the turntable rotates, it drives the first bending wheel to rotate around the axis of the turntable. When the first bending wheel rotates, it applies pressure to the air tube to cause the air tube to bend. Record the rotation angle of the turntable and detect the bending status of the bend in the aviation tube; When the rotation angle reaches the first angle, based on the bending state of the aviation pipe bending part, the positions of the first bending wheel and the second bending wheel are adjusted, and the second bending wheel is driven to rise through the second lifting component so that the second bending wheel and the positioning wheel are at the same height; The air pipe is bent by applying pressure to it using a second bending wheel, or by applying pressure to it simultaneously using a first bending wheel and a second bending wheel.

Pressure is applied to the air tube using a second bending wheel to cause it to bend, specifically including: The turntable is driven to rotate by a rotary drive assembly. When the turntable rotates, it drives the second bending wheel to rotate around the axis of the turntable. When the second bending wheel rotates, it applies pressure to the air tube to make the air tube bend. Alternatively, by controlling the drive speed of the lateral drive mechanism and the longitudinal drive mechanism, the second bending wheel is controlled to apply pressure to the air tube according to a preset trajectory to make the air tube bend.

[0013] In one embodiment of the present invention, the bending assembly further includes a third bending wheel group and a fourth bending wheel group. The third bending wheel group includes a third lifting component and a third bending wheel.

The fourth lifting component is mounted on the turntable and is used to drive the fourth bending wheel to perform lifting and lowering movements. When the rotation drive component drives the turntable to rotate, the turntable drives the first bending wheel group, the second bending wheel group, the third bending wheel group, and the fourth bending wheel group to rotate around the axis of the turntable. The linear drive assembly includes a first driver, a front end seat, a rear end seat, a rotating lead screw, and two guide rods. The two ends of the rotating lead screw and the guide rods are connected to the front end seat and the rear end seat, respectively. The two guide rods are located on both sides of the rotating lead screw. The first driver and the rotating lead screw are connected by a transmission. The base is threadedly engaged with the rotating lead screw, and the base is slidably engaged with the guide rod. The base is provided with an annular surrounding plate, and the bending component is set inside the annular surrounding plate. The turntable and the annular surrounding plate are coaxially arranged, and the projection of the axis of the aviation tube on the upper surface of the base is offset from the center of the annular surrounding plate. The upper surface of the seat is provided with a first counterweight cylinder and a second counterweight cylinder. The first counterweight cylinder and the second counterweight cylinder are located on the front side of the seat. The first counterweight cylinder and the positioning wheel are located on both sides of the aviation tube.

The first and second lifting components are used to control the first and second bending wheels to descend, respectively, and the third lifting component is used to control the third bending wheel to rise. The rotary drive assembly drives the turntable to rotate, and when the turntable rotates, it drives the third bending wheel to rotate around the axis of the turntable. When the third bending wheel rotates, it applies pressure to the air tube to make the air tube bend. When the rotation angle reaches the third angle, the position of the fourth bending wheel is adjusted based on the bending state of the aircraft tube bending part. The first, second and third bending wheels are lowered by the first lifting assembly, the second lifting assembly and the third lifting assembly respectively, and the fourth bending wheel is raised by the fourth lifting assembly.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: In the above-described solution of this application, firstly, supporting the aviation tube with a pipeline support assembly makes installation and positioning of the aviation tube more convenient and improves the stability of the aviation tube during bending. Secondly, the linear drive assembly can drive the bending assembly to move along the length direction of the base, allowing the bending assembly to move to the designated bending position. Simultaneously, the linear drive assembly can fine-tune the positions of the first and second bending wheels, improving the positioning accuracy of the first and second bending wheels. Furthermore, the bending assembly in this application includes a base, a turntable, a rotary drive assembly, a positioning wheel group, a first bending wheel group, and a second bending wheel group. The turntable has a central hole, and the lower end of the positioning rod is fixedly connected to the base, while the upper end extends through the central hole and connects to the positioning wheel. Thus, when the turntable rotates, it does not drive the positioning wheel to rotate, allowing the aviation tube to bend around the positioning wheel. When the rotary drive assembly drives the turntable to rotate, it can drive the first and second bending wheel groups to rotate around the positioning wheel, thereby applying pressure to the aviation tube using the first and / or second bending wheels, enabling the aviation tube to bend around the positioning wheel. In this process, when bending the aircraft tube, the second bending wheel can be lowered first via the second lifting assembly to prevent it from limiting the tube's movement. Then, the first bending wheel applies pressure to the tube, causing it to bend. When the tube bends to a preset angle or experiences abnormal stress, the position of the second bending wheel can be adjusted via the linear drive assembly and turntable, and then raised again via the second lifting assembly. The tube can then be bent using either the second bending wheel alone or simultaneously using both the first and second bending wheels. With this structure, the distances between the first and second bending wheels and the positioning wheel differ. By employing three bending methods—bending with the first bending wheel alone, bending with the second bending wheel alone, and bending with both wheels working in tandem—the bending torque can be adjusted. This allows for adjustments to the bending state of the aircraft tube when it is at a stress concentration point, by changing the bending method and torque, thereby reducing the likelihood of dents and improving the yield rate.

Detailed Implementation

[0018] The present invention will be further described in detail below with reference to specific embodiments, but the implementation of the present invention is not limited thereto.

[0019] Example 1: Please see Figures 1 to 12This invention provides a bending device for aero-tube 5 components to prevent dents, including a base 1, a pipe support assembly 2, a linear drive assembly 3, and a bending assembly 4. Both the pipe support assembly 2 and the linear drive assembly 3 are mounted on the base 1. The pipe support assembly 2 supports the aero-tube 5, and the linear drive assembly 3 drives the bending assembly 4 to move along the length of the base 1. The bending assembly 4 includes a seat 41, a turntable 42, a rotary drive assembly, a positioning wheel set 43, a first bending wheel set 44, and a second bending wheel set 45. The seat 41 is mounted on the linear drive assembly 3, and the turntable 42 is rotatably connected to the seat 41. The rotary drive assembly drives the turntable 42 to rotate. The positioning wheel set 43 includes a positioning rod and positioning wheels. The turntable 42 has a central hole, and the lower end of the positioning rod... Fixedly connected to the base 41, the upper end extends through the central hole and is connected to the positioning wheel; the first bending wheel group 44 includes a first lifting component and a first bending wheel. The first lifting component is mounted on the turntable 42 and is used to drive the first bending wheel to perform lifting and lowering movements. The second bending wheel group 45 includes a second lifting component and a second bending wheel. The second lifting component is mounted on the turntable 42 and is used to drive the second bending wheel to perform lifting and lowering movements. When the rotation drive component drives the turntable 42 to rotate, the turntable 42 drives the first bending wheel group 44 and the second bending wheel group 45 to rotate around the axis of the turntable 42. The distances between the first bending wheel and the second bending wheel and the positioning wheel are different. The aviation tube 5 is located between the positioning wheel and the first bending wheel, and / or, the aviation tube 5 is located between the positioning wheel and the second bending wheel.

[0020] In some embodiments of this application, such as Figure 1 , Figure 2 and Figure 3 As shown, the base 1 has a cuboid structure, and the linear drive assembly 3 is installed on the upper surface of the base 1. Both sides of the base 1 are provided with mounting strips, and the mounting strips are provided with multiple mounting holes. The mounting holes are elongated holes to facilitate the adjustment of the mounting position of the base 1.

[0021] In some embodiments of this application, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the pipeline support assembly 2 includes a frame, which is mounted on the front end seat 32 of the linear drive assembly 3. The upper part of the frame is provided with a through hole, an outer tube is sleeved inside the through hole, and an inner tube is sleeved inside the outer tube. The aviation pipe 5 is inserted into the inner tube, and a pad is also provided in the inner tube. The pad is located between the outer wall of the aviation pipe 5 and the inner wall of the inner tube to improve the stability of the aviation pipe 5 installation.

[0022] In some embodiments of this application, such as Figure 2 and Figure 3As shown, the base 41 is provided with an annular surrounding plate, and the turntable 42 is located inside the annular surrounding plate. The turntable 42 is rotatably connected to the annular surrounding plate. A rotating rod is fixed below the turntable 42, and the rotating rod and the turntable 42 are coaxially arranged. The rotating rod and the base 41 are rotatably connected by bearings. The rotary drive assembly includes a rotary motor, a worm gear, and a worm. The rotary motor is fixed on the base 1, the worm gear is sleeved on the rotating rod, and the worm gear is fixedly connected to the rotating rod. The worm gear and the worm mesh, and the worm is driven by the rotary motor. When the rotary motor drives the worm to rotate, the worm drives the worm gear to rotate, and when the worm gear rotates, it drives the turntable 42 to rotate through the rotating rod. The rotating rod has a central shaft hole that runs through it along its axial direction. The central shaft hole corresponds to the central hole on the turntable 42. A positioning rod passes through the central hole and the central shaft hole and is fixedly connected to the base 1.

[0023] In some embodiments of this application, both the first lifting assembly and the second lifting assembly are common existing lifting structures. Specifically, both the first and second lifting assemblies in this application include a lifting motor, a lifting screw, and a lifting sleeve. The lifting motor is fixed on the turntable 42, and the lifting screw and the lifting motor are connected by a coupling. The lifting sleeve is sleeved on the outside of the lifting screw, and the inner wall of the lifting sleeve is provided with internal threads. The lifting screw and the lifting sleeve are threaded together. When the lifting motor drives the lifting screw to rotate, the lifting screw drives the lifting sleeve to move along its axial direction to achieve lifting, thereby driving the first or second bent wheel to perform lifting motion. The lifting motor in this embodiment can be a circular motor.

[0024] In some embodiments of this application, the positioning wheel is rotatably connected to the positioning rod, and the positioning wheel can rotate freely on the positioning rod to further reduce the probability of denting when the aviation tube 5 is bent. The first bending wheel is rotatably connected to the sleeve of the first lifting assembly, and the first bending wheel can rotate freely on the sleeve of the first lifting assembly to further reduce the probability of denting when the aviation tube 5 is bent. The second bending wheel is rotatably connected to the sleeve of the second lifting assembly, and the second bending wheel can rotate freely on the sleeve of the second lifting assembly to further reduce the probability of denting when the aviation tube 5 is bent.

[0025] In some embodiments of this application, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the outer circumferential surfaces of the positioning wheel, the first bending wheel, and the second bending wheel are all concave arc surfaces. These arc surfaces match the outer circumferential surface of the aviation tube 5 to further reduce the probability of the aviation tube 5 denting when bending, thereby improving the yield and quality of the aviation tube 5.

[0026] In some embodiments of this application, such as Figures 7 to 9 As shown, Figure 7This diagram shows the aviation tube 5 in its unbent state. Figure 8 A schematic diagram is shown showing the bending of the aircraft tube 5 using only the first bending wheel. Figure 9 A schematic diagram is shown showing the bending of the aircraft tube 5 using only the second bending wheel. Figure 10 A schematic diagram is shown showing the simultaneous use of a first bending wheel and a second bending wheel to bend the aircraft tube 5. When bending the aircraft tube 5, the operator can adjust the bending method according to the bending state of the aircraft tube 5 to reduce the probability of dents occurring during bending.

[0027] In the above-described scheme of this application, firstly, by supporting the aviation pipe 5 with the pipeline support assembly 2, it is easier to install and position the aviation pipe 5, and the stability of the aviation pipe 5 when bending is improved. Secondly, the linear drive assembly 3 can drive the bending assembly 4 to move along the length direction of the base 1, so that the bending assembly 4 can move to the designated bending position. At the same time, the linear drive assembly 3 can also fine-tune the positions of the first bending wheel and the second bending wheel, improving the positioning accuracy of the first bending wheel and the second bending wheel. Furthermore, the bending assembly 4 in this application includes a base 41, a turntable 42, a rotary drive assembly, a positioning wheel group 43, a first bending wheel group 44, and a second bending wheel group 45. The turntable 42 has a central hole. The lower end of the positioning rod is fixedly connected to the base 41, and the upper end extends through the central hole and is connected to the positioning wheel. In this way, when the turntable 42 rotates, it will not drive the positioning wheel to rotate, and the aviation tube 5 can be bent around the positioning wheel. When the rotary drive assembly drives the turntable 42 to rotate, it can drive the first bending wheel group 44 and the second bending wheel group 45 to rotate around the positioning wheel. Thus, pressure can be applied to the aviation tube 5 using the first bending wheel and / or the second bending wheel, so that the aviation tube 5 can be bent around the positioning wheel. When the air pipe 5 is bent, the second bending wheel can be driven to descend first through the second lifting assembly to avoid the second bending wheel limiting the air pipe 5. Then, the first bending wheel applies pressure to the air pipe 5 to cause it to bend. When the air pipe 5 bends to a preset angle or when the air pipe 5 experiences abnormal force, the position of the second bending wheel can be adjusted through the linear drive assembly 3 and the turntable 42, and the second bending wheel can be driven to rise through the second lifting assembly. Then, the second bending wheel can be used alone to bend the air pipe 5, or the first bending wheel and the second bending wheel can be used simultaneously to bend the air pipe 5. When the above structure is adopted, the distance between the first bending wheel and the second bending wheel and the positioning wheel is different. By using three bending methods—bending with the first bending wheel alone, bending with the second bending wheel alone, and bending with the first bending wheel and the second bending wheel working together—the bending torque of the aircraft tube 5 can be adjusted. This allows the aircraft tube 5 to bend in a stress concentration position when it is prone to denting. By changing the bending method and the magnitude of the torque, the bending state of the aircraft tube 5 can be adjusted, thereby reducing the probability of the aircraft tube 5 denting and improving the yield of the aircraft tube 5.

[0028] In some embodiments of this application, such as Figure 2 , Figure 3 and Figure 5As shown, the first bending wheel assembly 44 also includes a first linear drive assembly, which is mounted on the upper surface of the turntable 42. A first lifting assembly is mounted on the first linear drive assembly. The first linear drive assembly drives the first lifting assembly to move in a direction perpendicular to the axis of the aircraft tube 5, thereby driving the first bending wheel closer to or further away from the aircraft tube 5. With this structure, the first linear drive assembly can drive the first lifting assembly to move in a direction perpendicular to the axis of the aircraft tube 5, thereby adjusting the distance between the first bending wheel and the aircraft tube 5. This avoids the aircraft tube 5 and the first bending wheel being mutually restricted when the first lifting assembly drives the first bending wheel to rise or fall, and also adjusts the torque applied by the first bending wheel to the aircraft tube 5, further reducing the probability of the aircraft tube 5 denting and improving the yield of the aircraft tube 5.

[0029] In one alternative approach, such as Figure 2 , Figure 3 and Figure 5 As shown, the distance between the first bending wheel and the positioning wheel is smaller than the distance between the second bending wheel and the positioning wheel. The second bending wheel assembly 45 also includes a second linear drive assembly, which is mounted on the upper surface of the turntable 42. A second lifting assembly is mounted on the second linear drive assembly. The second linear drive assembly is used to drive the second lifting assembly to move in a direction perpendicular to the axis of the aircraft tube 5, thereby driving the second bending wheel closer to or away from the aircraft tube 5. With this structure, the second linear drive assembly can drive the second lifting assembly to move in a direction perpendicular to the axis of the aircraft tube 5, thereby adjusting the distance between the second bending wheel and the aircraft tube 5. This avoids the aircraft tube 5 and the second bending wheel being mutually restricted when the second lifting assembly drives the second bending wheel to rise or fall, and also adjusts the magnitude of the torque applied by the second bending wheel to the aircraft tube 5, further reducing the probability of the aircraft tube 5 being dented and improving the yield of the aircraft tube 5.

[0030] In some embodiments of this application, both the first linear drive assembly and the second linear drive assembly include a motor, a slider, and a lead screw. A guide rail is provided on the turntable 42, the slider and the guide rail are slidably connected, the motor and the lead screw are drivenly connected, the slider and the lead screw are threadedly engaged, and the first lifting assembly or the second lifting assembly is mounted on the slider. When the motor drives the lead screw to rotate, the slider moves in a direction perpendicular to the axis of the aviation tube 5 to move closer to or away from the aviation tube 5.

[0031] In another alternative approach, such as Figure 11As shown, the bending device also includes a variable trajectory drive assembly, which comprises a lateral drive mechanism and a longitudinal drive mechanism. The lateral drive mechanism is arranged along the axial direction of the air tube 5, and the longitudinal drive mechanism is arranged along a direction perpendicular to the axial direction of the air tube 5. The lateral drive mechanism is mounted on the upper surface of the turntable 42, and the longitudinal drive mechanism is mounted on the lateral drive mechanism. The second lifting assembly is mounted on the longitudinal drive mechanism. With this structure, the second lifting assembly can be driven to move along a non-circular trajectory, such as an elliptical trajectory, through the lateral and longitudinal drive mechanisms. This further optimizes the bending method of the air tube 5, adjusts the torque applied to the air tube 5 by the first bending wheel in real time, further reduces the probability of the air tube 5 denting, and improves the yield of the air tube 5.

[0032] In some embodiments of this application, both the lateral drive mechanism and the longitudinal drive mechanism are common linear drive mechanisms. In this embodiment, both the lateral drive mechanism and the longitudinal drive mechanism include a motor, a lead screw, and a slider. The motor and the lead screw are connected by a transmission, and the lead screw and the slider are threaded together. When the motor drives the lead screw to rotate, it can drive the second bent wheel to move along a non-circular trajectory.

[0033] In some embodiments of this application, such as Figures 1 to 11As shown, the bending assembly 4 also includes a third bending wheel group 46 and a fourth bending wheel group 47. The third bending wheel group 46 includes a third lifting assembly and a third bending wheel. The third lifting assembly is mounted on the turntable 42 and is used to drive the third bending wheel to move up and down. The fourth bending wheel group 47 includes a fourth lifting assembly and a fourth bending wheel. The fourth lifting assembly is mounted on the turntable 42 and is used to drive the fourth bending wheel to move up and down. When the rotation drive assembly drives the turntable 42 to rotate, the turntable 42 drives the first bending wheel to move up and down. The first bending wheel group 44, the second bending wheel group 45, the third bending wheel group 46, and the fourth bending wheel group 47 rotate around the axis of the turntable 42; the first bending wheel, the second bending wheel, the third bending wheel, and the fourth bending wheel are distributed sequentially along the circumference of the turntable 42, the distance between the second bending wheel and the positioning wheel is less than the distance between the third bending wheel and the positioning wheel; the distance between the third bending wheel and the positioning wheel is less than the distance between the fourth bending wheel and the second bending wheel and the positioning wheel, and the distance between the third bending wheel and the positioning wheel is greater than the outer diameter of the aviation tube 5. With this structure, the distances between the first bending wheel group 44, the second bending wheel group 45, the third bending wheel group 46, and the fourth bending wheel group 47 and the positioning wheel are all different. The third bending wheel is driven to rise and fall by the third lifting component, and the fourth bending wheel is driven to rise and fall by the fourth lifting component. In this way, when the aircraft tube 5 is bent to different angles, the third and fourth bending wheels can be used to bend the aircraft tube 5, thereby adjusting the bending torque of the aircraft tube 5. When the aircraft tube 5 is in a stress concentration position, the bending state of the aircraft tube 5 can be adjusted by changing the bending method and the magnitude of the torque, thereby reducing the probability of the aircraft tube 5 denting and improving the yield of the aircraft tube 5. This application, through the coordinated operation of the first bending wheel, the second bending wheel, the third bending wheel and the fourth bending wheel, can fully optimize the bending method of the aviation tube 5. When the aviation tube 5 is in different bending states, different bending wheels can be used to bend the aviation tube 5, further reducing the probability of the aviation tube 5 denting and improving the yield of the aviation tube 5.

[0034] In some embodiments of this application, the third lifting assembly and the fourth lifting assembly have the same structure as the first lifting assembly, and the third bending wheel and the fourth bending wheel have the same structure as the first bending wheel.

[0035] In some embodiments of this application, the linear drive assembly 3 includes a first driver 31, a front end seat 32, a rear end seat 33, a rotating lead screw 34, and two guide rods 35. The two ends of the rotating lead screw 34 and the guide rods 35 are respectively connected to the front end seat 32 and the rear end seat 33. The two guide rods 35 are respectively located at the two ends of the rotating lead screw 34. The first driver 31 and the rotating lead screw 34 are connected by transmission. The seat body 41 is threadedly engaged with the rotating lead screw 34 and slidably engaged with the guide rods 35. The seat body 41 is provided with an annular surrounding plate. The bending assembly 4 is disposed inside the annular surrounding plate. The turntable 42 and the annular surrounding plate are coaxially arranged. The projection of the axis of the aviation tube 5 onto the upper surface of the seat body 41 is offset from the center of the annular surrounding plate. The upper surface of the seat body 41 is provided with a first counterweight cylinder 7 and a second counterweight cylinder 8. The first counterweight cylinder 7 and the second counterweight cylinder 8 are located on the front side of the seat body 41. The first counterweight cylinder 7 and the positioning wheel are respectively located on both sides of the aviation tube 5. The first counterweight cylinder 7 and the second counterweight cylinder 8 are each provided with a counterweight block. With this structure, when the first driver 31 drives the lead screw to rotate, the bending assembly 4 can move along the length of the base 1. Because the distances between the first bending wheel group 44, the second bending wheel group 45, the third bending wheel group 46, and the fourth bending wheel group 47 and the positioning wheel are all different, and the rotation center of the turntable 42 is misaligned with the aviation tube 5, a shift in the center of gravity occurs when different bending wheels are used to bend the aviation tube 5, affecting the bending effect of the aviation tube 5. This application uses counterweights in the first and second counterweight cylinders 7 and 8 to adjust the center of gravity of the bending assembly 4, thereby further improving the yield and quality of the aviation tube 5.

[0036] In some embodiments of this application, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 as well as Figure 12As shown, the bending device also includes an internal support assembly 6, which includes a mounting frame, a second driver, a lead screw, a sleeve, a connecting rod, and a multi-section core ball assembly 61. The mounting frame is fixed to the base 1, and the second driver is fixed to the mounting frame. The second driver and the lead screw are connected by a transmission. The sleeve is sleeved on the outside of the lead screw, and the lead screw and the sleeve are threaded together. One end of the connecting rod is connected to the sleeve, and the other end is connected to the multi-section core ball assembly 61. The end of the sleeve extends into the aviation tube 5. The lead screw, the sleeve, and the aviation tube 5 are coaxially arranged. The multi-section core ball assembly 61 includes multiple spheres, and a hinge rod is connected between two adjacent spheres. The two ends of the hinge rod are respectively hinged to two adjacent spheres. A pressure sensor is provided on the outer circumference of the spheres. With this structure, the interior of the aviation tube 5 can be supported by the spheres, further preventing the aviation tube 5 from denting and improving the yield of the aviation tube 5. Furthermore, the pressure sensor can detect the stress state of the aviation tube 5, thereby enabling the real-time adjustment of different bending methods based on different pressure values. This means using different bending wheels to bend the aviation tube, further improving the yield and quality of the aviation tube 5.

The turntable is driven to rotate by a rotary drive assembly. When the turntable rotates, it drives the first bending wheel to rotate around the axis of the turntable. When the first bending wheel rotates, it applies pressure to the air tube to cause the air tube to bend. Record the rotation angle of the turntable and detect the bending state of the bend in the aviation tube. Specifically, an angle sensor can be installed on the turntable to detect the rotation angle of the turntable. When the rotation angle reaches the first angle, based on the bending state of the aviation pipe bending part, the positions of the first bending wheel and the second bending wheel are adjusted, and the second bending wheel is driven to rise through the second lifting component so that the second bending wheel and the positioning wheel are at the same height; The air pipe is bent by applying pressure to it using a second bending wheel, or by applying pressure to it simultaneously using a first bending wheel and a second bending wheel.
