Description
Technical Field
[0001] The present invention belongs to the technical field of pipe fitting processing, and specifically relates to an intelligent multi-angle stamping pipe bender. Background Art
[0002] A pipe is a steel material with a hollow cross-section, and its length is much greater than the diameter or circumference. Steel pipes are not only used for transporting fluids and powdered solids, exchanging heat energy, manufacturing mechanical parts and containers, but also an economical steel material. Using steel pipes to manufacture building structure grids, supports, and mechanical brackets can reduce the weight, save 20-40% of metal, and can achieve factory mechanized construction. Using steel pipes to manufacture highway bridges can not only save steel, simplify construction, but also greatly reduce the area of the protective layer, saving investment and maintenance costs. During on-site use, it is necessary to bend the steel pipe according to the actual use requirements.
[0003] The existing pipe bending process has low precision, and it is difficult to perform small-angle pipe bending processing on pipes. During processing, it may be over-bent, resulting in the scrapping of the pipes. Moreover, different pipes have different mechanical properties. If the pipes are bent uniformly, some relatively fragile pipes are likely to break due to over-bending during the pipe bending process, and may even snap directly in severe cases, not only causing damage to the pipes, but also the flying debris posing a risk of injury. Summary of the Invention
[0004] Aiming at the deficiencies of the prior art, the present invention provides an intelligent multi-angle stamping pipe bender, which solves the problem that the pipe is prone to break due to excessive bending angle during pipe processing.
[0005] The technical solution adopted by the present invention to solve its technical problems is: An intelligent multi-angle stamping pipe bender of the present invention includes a large base plate. The front part of the upper surface of the large base plate is symmetrically provided with steering devices. The rear part of the upper surface of the large base plate is fixedly connected with a positioning base table. The upper part of the inner wall of the positioning base table is fixedly connected with an outer fixed cylinder. Through grooves are symmetrically opened on the upper and lower sides of the inner wall of the outer fixed cylinder. A double-layer clamping plate is slidably connected to the upper part of the inner wall of the outer fixed cylinder. The upper surface of the double-layer clamping plate is fixedly connected with a stamping motor. Before using this device for the pipe bending process, it is necessary to first insert the pipe to be processed into the inside of the outer fixed cylinder, and then extend one end of the pipe from the front end of the outer fixed cylinder. The front part of the outer surface of the pipe is clamped by the steering devices on both sides to complete the preparatory work.
[0006] Preferably, the steering device includes a fixed column, the top of the fixed column is fixedly connected with a small press, one side of the output port of the small press is fixedly connected with a hollow telescopic plate, one end of the hollow telescopic plate is fixedly connected with a thrust bending plate, the lower part of the outer surface of the thrust bending plate is fixedly connected with a vertical connecting plate, one side of the outer surface of the vertical connecting plate is fixedly connected with an adjusting spring group, and one end of the adjusting spring group is fixedly connected with a slide rail frame. When bending a pipe, according to the direction of bending required, select the steering device in the corresponding direction, start the corresponding small press, the small press pressurizes the inside of the hollow telescopic plate, the top of the hollow telescopic plate slides outwards, and then pushes the thrust bending plate to move in a direction perpendicular to the pipe. At this time, the spring structure inside the adjusting spring group is stretched. At this time, one side of the pipe is bent under the pushing action of the thrust bending plate. When the pipe bending is completed, the small press stops working, the pressure inside the hollow telescopic plate decreases, and under the combined action of the external air pressure and the adjusting spring group, the vertical connecting plate resets, and the thrust bending plate resets, thus completing the pipe bending process.
[0007] Preferably, the positioning base platform includes a trapezoidal housing, the middle part of the inner wall of the trapezoidal housing is fixedly connected with a hollow fixing plate, through grooves are symmetrically arranged on the left and right sides of the inner wall of the hollow fixing plate, and an alarm device is rotatably connected to the left and right sides of the inner wall of the hollow fixing plate through the through grooves, and an upper pressing device is fixedly connected to the middle part of the inner wall of the hollow fixing plate.
[0008] Preferably, the alarm device includes a push-button alarm, the middle part of the front surface of the push-button alarm is fixedly connected with a force-bearing soft plate, the central part of the bottom of the inner wall of the trapezoidal housing is fixedly connected with a fixed shaft rod, the middle part of the outer surface of the fixed shaft rod is rotatably connected with a connecting gear disc, external pressure rods are symmetrically arranged on the back of the upper surface of the connecting gear disc, transfer tooth columns are symmetrically arranged on the left and right sides of the outer surface of the connecting gear disc, an extension rod is fixedly connected to the top of the upper surface of the transfer tooth column, an elastic connecting arm is fixedly connected to the lower part of the outer surface of the extension rod, an indicating needle is fixedly connected to the front part of the upper surface of the elastic connecting arm, and angle dials are symmetrically arranged on the front surface of the trapezoidal housing. Taking the steering device on the left as an example, when the thrust bending plate is performing the pipe bending process, the vertical connecting plate slides towards the middle of the slide rail frame under the traction of the thrust bending plate. At this time, the vertical connecting plate rotates the elastic connecting arm with the extension rod as the center, and the elastic connecting arm gradually elongates. If the bending angle of the pipe is small, at this time, the elastic connecting arm has not yet separated from the inner wall of the angle dial, and the indicating needle rotates with the rotation of the elastic connecting arm, thereby indicating the reading of the angle dial. The user can control the bending angle of the pipe according to the reading. When the angle reaches the standard, the small press stops working, and the pipe bending processing is completed.
[0009] Preferably, the number of the steering devices is two. The bottom end of the fixed column is fixedly connected to the inner wall of the large bottom plate through a notch. The top end of the fixed column is fixedly connected to the lower surface of the small press. The lower surface of the slide rail frame is fixedly connected to the center of the upper surface of the large bottom plate. The inner wall of the slide rail frame is slidably connected to the lower part of the outer surface of the vertical connecting plate. One end of the adjusting spring group is fixedly connected to one side of the inner wall of the slide rail frame, and the other end of the adjusting spring group is fixedly connected to the inner cavity of the vertical connecting plate.
[0010] Preferably, a transverse cutting groove is formed in the front part of the inner wall of the trapezoidal housing. The front end of the elastic connecting arm extends to the outside of the trapezoidal housing through the transverse cutting groove. The front end of the elastic connecting arm is fixedly connected to the back of the outer surface of the vertical connecting plate. The front part of the outer surface of the elastic connecting arm is movably connected to the inner cavity of the trapezoidal housing through the transverse cutting groove. The upper surface of the indicating needle is slidably connected to the upper part of the inner wall of the angle dial. The lower part of the outer surface of the elastic connecting arm is slidably connected to the lower part of the inner wall of the angle dial. The outer surface of the extension rod is rotatably connected to the inner cavity of the hollow fixing plate through a through rotating groove. The lower surface of the connecting gear column is rotatably connected to the lower part of the inner wall of the trapezoidal housing. The middle part of the outer surface of the connecting gear column is meshed with the outer surface of the connecting gear disk. The upper surface of the fixed shaft rod is fixedly connected to the middle part of the lower surface of the hollow fixing plate. The back of the outer surface of the push-button alarm is fixedly connected to the back of the inner wall of the trapezoidal housing. The outer surface of the force-bearing soft plate is movably connected to the top end of the outer surface of the external pressure rod. If the bending angle of the pipe is too large, at this time the elastic connecting arm disengages from the inner wall of the angle dial. The bottom end of the elastic connecting arm controls the connecting gear column to rotate counterclockwise through the extension rod. When the connecting gear column rotates, it controls the connecting gear disk to rotate clockwise through meshing connection. During the process of the connecting gear disk rotating clockwise, the left external pressure rod gradually comes into contact with the outer surface of the force-bearing soft plate. As the rotation angle of the connecting gear disk continuously increases, the left external pressure rod presses the force-bearing soft plate. At this time, the button of the push-button alarm on the other side of the outer surface of the force-bearing soft plate is pressed, and the push-button alarm starts to work and emits an alarm sound, prompting the user that no further bending can be performed, otherwise the pipe may break.
[0011] Preferably, the number of the external pressure rods is two. The external pressure rods are symmetrically arranged on both sides of the upper surface of the fixed shaft rod. The included angle between the external pressure rod and the vertical plane is °.
[0012] Preferably, the upper pressing device includes a power device. A through hole is provided at the center of the upper part of the inner wall of the hollow fixing plate. A threaded sleeve is fixedly connected to the middle of the upper surface of the hollow fixing plate. The upper surface of the threaded sleeve is movably connected to a plug pusher. The top end of the plug pusher is fixedly connected to a lower clamping plate. After inserting the pipe into the outer fixing cylinder of the device, the user controls the stamping motor to press the double-layer clamping plate downward. The lower surface of the double-layer clamping plate presses the upper surface of the pipe tightly. Then the torque rotator is started and rotated clockwise. The output shaft of the torque rotator drives the external thread insert to rotate clockwise through the vertical slide bar. Since the outer surface of the external thread insert is bolted to the inner wall of the threaded sleeve, the external thread insert spirally ascends along the inner wall of the threaded sleeve, gradually pushing the plug pusher upward. The plug pusher then pushes the lower clamping plate upward to cooperate with the double-layer clamping plate to clamp the pipe tightly.
[0013] Preferably, a slot is provided in the middle of the upper part of the inner wall of the trapezoidal housing. The outer surface of the plug pusher is slidably connected to the inner cavity of the trapezoidal housing through the slot. The top end of the plug pusher extends to the outside of the trapezoidal housing through the slot.
[0014] Preferably, the power device includes a torque rotator. Vertical slide bars are evenly fixedly connected to the outer surface of the output shaft of the torque rotator. An external thread insert is slidably connected to the outer surface of the output shaft of the torque rotator through the vertical slide bars. A buffer end is fixedly connected to the top end of the external thread insert.
[0015] The beneficial effects of the present invention are as follows: 1. The diameters of the pipes inserted into the inner part of the outer fixing cylinder are different. Therefore, the inner diameter of the outer fixing cylinder is relatively large to accommodate pipes with larger diameters. However, the outer fixing cylinder cannot fix pipes with smaller diameters. During bending, the pipes will become loose, resulting in a worse bending effect. In severe cases, the pipes will be scrapped due to unqualified bending angles. The pipe orifice of this device can adjust and clamp the processed pipe fittings to prevent the bent pipes from loosening.
[0016] 2. Because the inner diameter of the fixing cylinder of this device is relatively large, this device can process more different types and sizes of bent pipes, making the device more adaptable and more compatible with pipes.
[0017] 3. If the bending angle of the pipe is small, at this time, the elastic connecting arm has not yet separated from the inner wall of the angle dial. The indicating needle rotates with the rotation of the elastic connecting arm, thereby indicating the reading of the angle dial. The user can control the bending angle of the pipe according to the reading and relatively accurately complete the bending work with a small angle.
[0018] 4. If the bending angle of the pipe is too large, as the rotation angle of the connecting gear disc continuously increases, the external pressure rod on the left side presses the force-bearing flexible plate. At this time, the button of the pressing-type alarm on the other side of the outer surface of the force-bearing flexible plate is pressed, and the pressing-type alarm starts to work and emits an alarm sound, thereby reminding the user that the bending angle may be too large during the bending operation and the pipe may break. After hearing the alarm sound, the user stops the bending operation to prevent the pipe from breaking due to excessive bending.
[0019] 5. If a relevant pusher is used to directly push the plug pusher upward, the same effect can be achieved. However, because the stroke between the lower clamping plate and the pipe fitting is too short, and there is a buffer distance during the start and stop of a general pusher, the pipe is very likely to be deformed due to excessive extrusion, causing deformation and indentation on the extruded part of the pipe, and may even be deformed severely. When using this device for pipe extrusion, there is no need to worry about the over-rotation of the torque rotator because the stroke between the lower clamping plate and the pipe fitting can be extended through the thread, allowing sufficient buffer time between the upper surface of the lower clamping plate and the lower surface of the pipe fitting, thereby effectively avoiding the adverse effects of the pipe being likely to be deformed due to excessive extrusion, generating indentation, and even being deformed severely.
[0020] 6. In the present invention, the slide rail frame and the adjustment spring group are respectively used to limit the two sides of the thrust bending plate. After the thrust bending plate is processed, the adjustment spring group resets, and then the thrust bending plate is pulled back to its original position through the vertical connecting plate, thereby ensuring that the thrust bending plate can accurately return to its original position after each operation, preventing deviation in the caliber between the steering device and the outer fixing cylinder, and thus affecting the bending effect of the subsequent pipe bending.

Before using the device for pipe bending, it is necessary to insert the pipe to be processed into the interior of the outer fixed tube 4, and then extend one end of the pipe from the front end of the outer fixed tube 4, and the front part of the outer surface of the pipe is clamped by the steering devices 2 on both sides to complete the preliminary preparation work. Because the inner diameter of the fixed tube 4 of the device is relatively large, the device can process more bent pipes of different models and sizes, thereby making the device more adaptable and more compatible with pipes.

One side of the outer surface of the vertical connecting plate 25 is fixedly connected to an adjusting spring group 27. One end of the adjusting spring group 27 is fixedly connected to a slide rail frame 26. When bending a pipe, according to the direction of bending required, select the corresponding steering device 2, start the corresponding small press 22. The small press 22 pressurizes the inside of the hollow telescopic plate 23, and the top of the hollow telescopic plate 23 slides outwards, thereby pushing the thrust bending plate 24 to move in a direction perpendicular to the pipe. At this time, the spring structure inside the adjusting spring group 27 is stretched. At this time, one side of the pipe is bent under the pushing action of the thrust bending plate 24. When the pipe bending is completed, the small press 22 stops working, the pressure inside the hollow telescopic plate 23 decreases, and under the combined action of the external air pressure and the adjusting spring group 27, the vertical connecting plate 25 resets, and the thrust bending plate 24 resets, thereby completing the pipe bending process. In the present invention, by setting the slide rail frame 26 and the adjusting spring group 27 to limit the two sides of the thrust bending plate 24 respectively, when the thrust bending plate 24 is processed, the adjusting spring group 27 resets, and then the thrust bending plate 24 is pulled back to its original position through the vertical connecting plate 25, thereby ensuring that the thrust bending plate 24 can accurately return to its original position after each operation, preventing deviation in the caliber between the steering device 2 and the outer fixed cylinder 4, and thus affecting the bending effect of the subsequent pipe bending.
[0026] The positioning base 3 includes a trapezoidal housing 31. The middle part of the inner wall of the trapezoidal housing 31 is fixedly connected to a hollow fixing plate 32. Through slots are symmetrically opened on the left and right sides of the inner wall of the hollow fixing plate 32. The left and right sides of the inner wall of the hollow fixing plate 32 are rotatably connected to an alarm device 7 through the through slots.

[0027] The alarm device 7 includes a push-button alarm 71. In the middle of the front surface of the push-button alarm 71, a stress soft plate 72 is fixedly connected.

At the top of the upper surface of the transfer tooth column 76, an extension rod 79 is fixedly connected. At the lower part of the outer surface of the extension rod 79, an elastic connecting arm 77 is fixedly connected. At the front part of the upper surface of the elastic connecting arm 77, an indicating needle 78 is fixedly connected. On the front surface of the trapezoidal housing 31, an angle dial 710 is symmetrically arranged. Taking the steering device 2 on the left as an example, when the thrust bending plate 24 is performing the pipe bending process, the vertical connecting plate 25 slides towards the middle of the slide rail frame 26 under the traction of the thrust bending plate 24. At this time, the vertical connecting plate 25 rotates the elastic connecting arm 77 with the extension rod 79 as the center, and the elastic connecting arm 77 gradually elongates. If the bending angle of the pipe is small, at this time, the elastic connecting arm 77 has not yet separated from the inner wall of the angle dial 710, and the indicating needle 78 rotates with the rotation of the elastic connecting arm 77, thereby indicating the reading of the angle dial 710. The user can control the bending angle of the pipe according to the reading and relatively accurately complete the pipe bending work with a small angle.
[0028] The number of the steering devices 2 is two. The bottom end of the fixed column 21 is fixedly connected to the inner wall of the large bottom plate 1 through a notch. The top end of the fixed column 21 is fixedly connected to the lower surface of the small pressurizing machine 22. The lower surface of the slide rail frame 26 is fixedly connected to the center of the upper surface of the large bottom plate 1. The inner wall of the slide rail frame 26 is slidably connected to the lower part of the outer surface of the vertical connecting plate 25. One end of the adjustment spring group 27 is fixedly connected to one side of the inner wall of the slide rail frame 26, and the other end of the adjustment spring group 27 is fixedly connected to the inner cavity of the vertical connecting plate 25.
[0029] A transverse cutting groove is formed in the front part of the inner wall of the trapezoidal housing 31. The front end of the elastic connecting arm 77 extends to the outside of the trapezoidal housing 31 through the transverse cutting groove. The front end of the elastic connecting arm 77 is fixedly connected to the back of the outer surface of the vertical connecting plate 25. The front part of the outer surface of the elastic connecting arm 77 is movably connected to the inner cavity of the trapezoidal housing 31 through the transverse cutting groove. The upper surface of the indicating needle 78 is slidably connected to the upper part of the inner wall of the angle dial 710. The lower part of the outer surface of the elastic connecting arm 77 is slidably connected to the lower part of the inner wall of the angle dial 710. The outer surface of the extension rod 79 is rotatably connected to the inner cavity of the hollow fixing plate 32 through a through rotation groove. The lower surface of the transfer tooth column 76 is rotatably connected to the lower part of the inner wall of the trapezoidal housing 31. The middle part of the outer surface of the transfer tooth column 76 is meshed with the outer surface of the connecting gear disk 74. The upper surface of the fixed shaft rod 73 is fixedly connected to the middle part of the lower surface of the hollow fixing plate 32. The back of the outer surface of the push-button alarm 71 is fixedly connected to the back of the inner wall of the trapezoidal housing 31. The outer surface of the force-bearing soft plate 72 is movably connected to the top of the outer surface of the external pressure rod 75. If the bending angle of the pipe is too large, at this time, the elastic connecting arm 77 disengages from the inner wall of the angle dial 710. The bottom end of the elastic connecting arm 77 controls the transfer tooth column 76 to rotate counterclockwise through the extension rod 79. When the transfer tooth column 76 rotates, it controls the connecting gear disk 74 to rotate clockwise through meshing connection. During the process of the connecting gear disk 74 rotating clockwise, the left external pressure rod 75 gradually comes into contact with the outer surface of the force-bearing soft plate 72. As the rotation angle of the connecting gear disk 74 continuously increases, the left external pressure rod 75 presses the force-bearing soft plate 72. At this time, the button of the push-button alarm 71 on the other side of the outer surface of the force-bearing soft plate 72 is pressed, and the push-button alarm 71 starts to work and emits an alarm sound, prompting the user that no further bending can be carried out, otherwise the pipe may break.
[0030] The number of the external pressure rods 75 is two. The external pressure rods 75 are symmetrically arranged on both sides of the upper surface of the fixed shaft rod 73. The included angle between the external pressure rod 75 and the vertical plane is 45°.
[0031] The upper pressing device 8 includes a power device 9. At the axis of the upper part of the inner wall of the hollow fixing plate 32, a through hole is provided. In the middle of the upper surface of the hollow fixing plate 32, a threaded sleeve 81 is fixedly connected. On the upper surface of the threaded sleeve 81, a plug pusher 82 is movably connected. At the top of the plug pusher 82, a lower clamping plate 83 is fixedly connected. After inserting the pipe into the outer fixing cylinder 4 of the device, the user controls the stamping motor 5 to press the double-layer clamping plate 6 downward. The lower surface of the double-layer clamping plate 6 presses the upper surface of the pipe tightly. Subsequently, the torque rotator 91 starts and rotates clockwise. The output shaft of the torque rotator 91 drives the external thread insert 93 to rotate clockwise through the vertical slide bar 92. Since the outer surface of the external thread insert 93 is bolted to the inner wall of the threaded sleeve 81, the external thread insert 93 spirally ascends along the inner wall of the threaded sleeve 81, gradually pushing the plug pusher 82 upward. The plug pusher 82 then pushes the lower clamping plate 83 upward to cooperate with the double-layer clamping plate 6 to clamp the pipe. If a relevant pusher is used to directly push the plug pusher 82 upward, the same effect can also be achieved. However, because the stroke between the lower clamping plate 83 and the pipe fitting is too short, and there is a buffer distance during the start and stop of a general pusher, the pipe is very likely to be deformed due to excessive extrusion, causing deformation and indentation on the extruded part of the pipe, and may even be deformed severely in serious cases.
[0032] In the middle of the upper part of the inner wall of the trapezoidal housing 31, a slot is provided. The outer surface of the plug pusher 82 is slidably connected to the inner cavity of the trapezoidal housing 31 through the slot, and the top of the plug pusher 82 extends to the outside of the trapezoidal housing 31 through the slot.
[0033] The power device 9 includes a torque rotator 91. On the outer surface of the output shaft of the torque rotator 91, vertical slide bars 92 are uniformly fixedly connected. The outer surface of the output shaft of the torque rotator 91 is slidably connected with an external thread insert 93 through the vertical slide bars 92. At the top of the external thread insert 93, a buffer end 94 is fixedly connected. When using this device for pipe extrusion, there is no need to worry about the over-rotation of the torque rotator 91, because the stroke between the lower clamping plate 83 and the pipe fitting can be extended by the thread, so that there is enough buffer time between the upper surface of the lower clamping plate 83 and the lower surface of the pipe fitting, thus effectively avoiding the adverse effects that the pipe is very likely to be deformed due to excessive extrusion, resulting in indentation and even being deformed severely in serious cases.
[0034] The specific working process is as follows: Before using this device for the pipe bending process, it is necessary to first insert the pipe to be processed into the inner part of the outer fixing cylinder 4, and then extend one end of the pipe out of the front end of the outer fixing cylinder 4. The front part of the outer surface of the pipe is clamped by the steering devices 2 on both sides, completing the preparatory work.
[0035] When bending a pipe, according to the direction of bending required, select the steering device 2 in the corresponding direction, start the corresponding small press 22, the small press 22 pressurizes the inside of the hollow telescopic plate 23, the top of the hollow telescopic plate 23 slides outwards, and then pushes the thrust bending plate 24 to move in a direction perpendicular to the pipe. At this time, the spring structure inside the spring group 27 is stretched. At this time, one side of the pipe is bent under the pushing action of the thrust bending plate 24. When the pipe bending is completed, the small press 22 stops working, the pressure inside the hollow telescopic plate 23 decreases, and under the combined action of the external air pressure and the spring group 27, the vertical connecting plate 25 resets, and the thrust bending plate 24 resets, thus completing the pipe bending process. In the present invention, by providing the slide rail frame 26 and the spring group 27 to limit the two sides of the thrust bending plate 24 respectively. After the thrust bending plate 24 is processed, the spring group 27 resets, and then the thrust bending plate 24 is pulled back to its original position through the vertical connecting plate 25, so as to ensure that the thrust bending plate 24 can accurately return to its original position after each operation, preventing deviation in the diameters of the steering device 2 and the outer fixing cylinder 4, and thus affecting the bending effect of the subsequent pipe bending.
[0036] Taking the steering device 2 on the left as an example, when the thrust bending plate 24 is performing the pipe bending process, the vertical connecting plate 25 slides towards the middle of the slide rail frame 26 under the traction of the thrust bending plate 24. At this time, the vertical connecting plate 25 rotates the elastic connecting arm 77 with the extension rod 79 as the center, and the elastic connecting arm 77 gradually elongates. If the bending angle of the pipe is small, at this time, the elastic connecting arm 77 has not yet separated from the inner wall of the angle dial 710, and the indicating needle 78 rotates with the rotation of the elastic connecting arm 77, thereby indicating the reading of the angle dial 710. The user can control the bending angle of the pipe according to the reading. When the angle reaches the standard, the small press 22 stops working, and the pipe bending process is completed. If the bending angle of the pipe is too large, at this time, the elastic connecting arm 77 separates from the inner wall of the angle dial 710, and the bottom end of the elastic connecting arm 77 controls the transfer tooth column 76 to rotate counterclockwise through the extension rod 79. When the transfer tooth column 76 rotates, it controls the connecting gear disk 74 to rotate clockwise through meshing connection. During the process of the connecting gear disk 74 rotating clockwise, the left external pressure rod 75 gradually contacts the outer surface of the force-bearing soft plate 72. As the rotation angle of the connecting gear disk 74 continuously increases, the left external pressure rod 75 presses the force-bearing soft plate 72. At this time, the button of the push-button alarm 71 on the other side of the outer surface of the force-bearing soft plate 72 is pressed, and the push-button alarm 71 starts to work and emits an alarm sound, prompting the user that no further bending can be performed, otherwise the pipe may break. After hearing the alarm sound, the user stops the pipe bending work to prevent the pipe from breaking due to excessive bending.
[0037] The diameters of the pipes inserted into the inner part of the external fixing cylinder 4 are different. Therefore, the inner diameter of the external fixing cylinder 4 is relatively large to accommodate pipes with larger diameters. However, the external fixing cylinder 4 cannot fix pipes with smaller diameters. During bending, the pipes will become loose, resulting in a worse bending effect. In severe cases, the pipes will be scrapped due to unqualified bending angles. After inserting the pipe into the external fixing cylinder 4 of the device, the user controls the stamping motor 5 to press the double-layer clamping plate 6 downward. The lower surface of the double-layer clamping plate 6 presses tightly against the upper surface of the pipe. Subsequently, the torque rotating machine 91 is started and rotates clockwise. The output shaft of the torque rotating machine 91 drives the external thread insert 93 to rotate clockwise through the vertical sliding bar 92. Since the outer surface of the external thread insert 93 is bolted to the inner wall of the threaded pipe sleeve 81, the external thread insert 93 spirally ascends along the inner wall of the threaded pipe sleeve 81, gradually pushing the plug pushing member 82 upward. The plug pushing member 82 then pushes the lower clamping plate 83 upward to cooperate with the double-layer clamping plate 6 to clamp the pipe.
[0038] If a relevant pusher is directly used to push the plug pushing member 82 upward, the same effect can be achieved. However, because the stroke between the lower clamping plate 83 and the pipe fitting is too short, and there is a buffer distance during the start and stop of a general pusher, the pipe is very likely to be deformed due to excessive extrusion, causing deformation and indentation on the extruded part of the pipe. In severe cases, it may even be pressed out of shape. When using this device for pipe extrusion, there is no need to worry about the over-rotation of the torque rotating machine 91 because the stroke between the lower clamping plate 83 and the pipe fitting can be extended through the thread, providing sufficient buffer time between the upper surface of the lower clamping plate 83 and the lower surface of the pipe fitting. Thus, the adverse effects of the pipe being likely to be deformed due to excessive extrusion, resulting in indentation and even being pressed out of shape in severe cases, are effectively avoided.
