Description

Technical Field

[0001] The utility model relates to the technical field of pipe cutting, in particular to an automatic continuous pipe cutting device. Background Art

[0002] Using a laser pipe cutting machine to cut pipes can not only provide extremely high precision, but also the cutting edge is smooth and burr-free, without the need for subsequent grinding or trimming work. In order to further improve the level of automated production and enable one person to control and manage multiple devices simultaneously, a laser pipe cutting machine is generally equipped with a loading rack and a receiving rack to work together. Since the weight of small-diameter pipes is relatively light and the cutting task is large, it is urgent to develop an automatic continuous pipe cutting device. It is hoped that with the mutual cooperation of the laser pipe cutting machine and the automatic loading rack, the pipes in the material storage can be transported to the laser pipe cutting machine one by one in an orderly manner to achieve batch automatic continuous cutting. However, when using the existing automatic loading rack for auxiliary loading, it is particularly prone to jamming. The automatic loading rack can neatly arrange multiple pipes placed in the material placing component on the discharging component in sequence. Through the lifting component, one pipe can be separated from multiple pipes, and then the pushing component can push the pipe to the subsequent laser pipe cutting machine. The jamming mainly occurs when the pipes are transported to the discharging component for arrangement. When jamming occurs, the staff needs to stop the machine for debugging to solve the problem, which seriously affects the production rhythm and efficiency of automated production.

[0026] The present utility model provides an automatic continuous pipe cutting device. To make the objectives, technical solutions and effects of the present utility model clearer and more definite, the following further describes the present utility model in detail with reference to the accompanying drawings and by way of examples. It should be understood that the specific examples described herein are only used to explain the present utility model and are not used to limit the protection scope of the present utility model.

[0027] Please refer to Figures 1-6 , the present utility model provides an automatic continuous pipe cutting device, including a side hanging rack 1, a gantry 2 arranged beside the side hanging rack 1, a laser cutting assembly 3 arranged on the gantry 2 and movable along the X-axis and Z-axis, a rear chuck assembly 4 and a front chuck assembly 5 slidably arranged along the Y-axis on the side hanging rack 1, an automatic loading rack 6 arranged upstream of the gantry 2 and beside the side hanging rack 1, and a receiving rack 7 arranged downstream of the gantry 2 and beside the side hanging rack 1. The front chuck assembly 5 is arranged adjacent to the gantry 2. A centering support mechanism 8 is arranged on the side hanging rack 1. The automatic loading rack 6 includes at least three groups of spaced-apart rack modules 61. Each rack module 61 includes a bottom rack 611, a corner rack 612 arranged on the bottom rack 611, a material distribution station 613 arranged at the top corner of the corner rack 612, a first material blocking assembly 62 for intercepting and releasing the pipes at the material distribution station 613, a material distribution assembly 63 for screening out single pipes from multiple pipes at the material distribution station 613, and a material library pulling and feeding assembly 64 for serving as a pipe material library and pulling multiple pipes to the material distribution station 613. An inlet inclined bar 614 for guiding the pipes to slide into the material distribution station 613 and an outlet inclined shaft 615 for guiding the pipes at the material distribution station 613 to slide forward are arranged on the corner rack 612. A to-be-fed station 653 is arranged at the tail end of the outlet inclined shaft 615. The to-be-fed station 653 intercepts and releases the pipes through a second material blocking assembly 65. An upper loading station 682 is arranged downstream of the to-be-fed station 653. The upper loading station 682 intercepts the sliding pipes through a positioning stop block 681. The material distribution assembly 63 includes a pushing slide plate 631 slidably arranged on the corner rack 612, a pushing driving mechanism 632 for driving the pushing slide plate 631 to move, a lifting slide plate 633 slidably arranged on the pushing slide plate 631, a lifting driving mechanism 634 for driving the lifting slide plate 633 to lift and lower, a pushing bar 635 arranged on the end face of the lifting slide plate 633 facing the material distribution station 613, a stacking pushing block 636 slidably arranged on the lifting slide plate 633, and a pushing and stacking driving mechanism 637 for driving the stacking pushing block 636 to move. The centering support mechanism 8 is used to transfer the pipes at the upper loading station 682 and lift the pipes to a set height after centering.

[0028] Taking the example of three groups of rack modules 61, the staff stores a certain number of small tubes in the material storage area 641 of the material storage pulling assembly 64. The pull belt 642 of the material storage pulling assembly 64 of the leftmost rack module 61 supports the tube, the pull belt 642 of the material storage pulling assembly 64 of the middle rack module 61 supports the middle part of the tube, and the pull belt 642 of the material storage pulling assembly 64 of the rightmost rack module 61 supports the right end part of the tube. With the support of three contact points, the tube can be ensured to be straight and the middle part of the tube will not sink. When the pull belt 642 is wound, the pull belt 642 will drive the pipes in the material storage area 641 to rise, and under the guidance of the inlet bevel bar 614, multiple pipes will flow into the material distribution station 613 and fall on the outlet bevel shaft 615, and these pipes are temporarily stored in the material distribution station 613 under the interception of the first material blocking assembly 62. It can be understood that at this time, the pipes on the material distribution station 613 are irregularly arranged front and back and stacked together up and down under the action of gravity.

[0029] Then the material dividing assembly 63 screens the part of the pipes. Specifically, the material dividing assembly 63 is located downstream of the material dividing station 613, and the lifting drive mechanism 634 drives the lifting slide 633 to rise, so that the pushing strip 635 and the stacking pushing block 636 are higher than the output inclined shaft 615. Then the pushing drive mechanism 632 pushes the pushing slide 631 toward the material dividing station 613, so that the pushing strip 635 drives the multiple pipes to move backward, and then pushes the pipes arranged at the back away from the output inclined shaft. The shaft 615 falls back into the material storage area 641, and the pipe in the front (i.e., close to the pushing bar 635) remains on the material dividing station 613, and then the stacking drive mechanism 637 drives the stacking push block 636 to extend backward. If there is stacking at the material dividing station 613 at this time, the stacking push block 636 will push the stacked pipes on it into the material storage area 641. Therefore, after screening by the material dividing assembly 63, only one pipe to be processed is left at the material dividing station 613.

[0030] The lifting drive mechanism 634 drives the lifting slide 633 to descend and reset. As the pushing bar 635 and the stacking pushing block 636 descend and withdraw, the pipe to be processed will move downward along the smooth lead-out inclined axis 615 to the first blocking assembly 62 under the action of gravity, and then the first blocking assembly 62 releases the pipe. The pipe slides forward to the feeding station 653 and is intercepted by the second blocking assembly 65. When the laser pipe cutting machine is ready for loading and processing, the second blocking assembly 65 will release the pipe, allowing the pipe to continue to slide forward to the loading station 682.

[0031] The centering support mechanism 8 centers and positions the pipe at the loading station 682 and lifts the pipe to be coaxial with the front chuck assembly 5 and the rear chuck assembly 4. The pipe will be clamped by the front chuck assembly 5 and the rear chuck assembly 4, and the rear chuck assembly 4 will push the pipe forward towards the laser cutting assembly 3 to achieve cutting feed. The laser cutting assembly 3 emits laser downward to cut the pipe fittings. The cut pipe segments will be received by the receiving rack 7 and slide into the finished product storage tray to achieve unloading.

[0032] The automatic continuous pipe cutting equipment provided by the present invention realizes the batch continuous supply and cutting of pipes through the efficient cooperation of the automatic loading rack 6 and the laser pipe cutting machine, avoids manual intervention, and significantly improves the production efficiency and automation level. Through the improvement of the automatic loading rack 6, the cooperation of the export inclined shaft 615 and the first material blocking assembly 62 forms an open feeding station 613. The material storage pulling assembly 64 only needs to pull multiple pipes to the feeding station 613. The pushing bar 635 and the stacking pushing block 636 of the feeding assembly 63 work together to accurately screen out single pipes from the irregularly arranged multiple pipes in the feeding station 613, and the excess pipes fall back into the material storage area 641, fundamentally solving the problem of material jamming caused by the need to regularly arrange pipes in the traditional pipe loading rack, ensuring the smooth process of the pipe from loading to cutting, and significantly improving the production efficiency and automation level of the laser pipe cutting machine. One worker can simultaneously control and manage multiple automatic continuous pipe cutting equipment, greatly reducing the manpower requirement and lowering the labor intensity.

[0033] In this embodiment, a material storage area 641 is formed upstream of the angle bracket 612, and a very large number of pipes to be processed are stored in the material storage area 641. The material storage pulling assembly 64 includes a pulling belt 642, a second rotating shaft 643 rotatably connected to the bottom frame 611, a winding wheel 644 sleeved on the second rotating shaft 643, and a transition wheel 645 rotatably connected to the angle bracket 612. One end of the pulling belt 642 is fixed to the bottom frame 611, and after winding around the transition wheel 645, the other end of the pulling belt 642 is connected to the winding wheel 644. During loading, the winding wheel 644 winds the pulling belt 642 to lift the pipes in the material storage area 641 upward by the pulling belt 642, so that a part of the pipes flow into the feeding station 613. The winding action of the winding wheel 644 can be accurately controlled. By adjusting the rotation speed and amplitude of the winding wheel 644, the tension of the pulling belt 642 can be controlled, thereby controlling the conveying speed and quantity of the pipes, improving the automation level and the controllability of the operation.

[0034] Further, the second rotating shafts 643 of two adjacent rack modules 61 are drivingly connected through a second synchronizing shaft 646, and the second rotating shaft 643 of one of the rack modules 61 is drivingly connected to a second reduction motor 647. By using one second reduction motor 647, the second rotating shafts 643 of multiple rack modules 61 can be driven, reducing the number of required motors, simplifying the control system, and lowering the initial investment and long-term operating costs of the equipment. The second synchronizing shaft 646 ensures the synchronous operation of adjacent rack modules 61 when winding the pulling belt 642, making the pulling process of the pipes in the pipe storage area 641 smoother and more coordinated, and avoiding uneven stress or jamming of the pipes caused by asynchronous operation.

[0035] Specifically, a first guide rail 6381 with the same slope as the export inclined shaft 615 is provided on the back of the pushing slide plate 631, and a first slider 6382 slidably connected to the first guide rail 6381 is fixed on the side surface of the angle bracket 612, ensuring the linear movement of the pushing slide plate 631 during the pushing operation, improving the stability and accuracy of the pushing process, and avoiding the position deviation of the pipes caused by the offset of the slide plate.

[0036] Further, the pushing driving mechanism 632 includes a rack provided on the pushing slide plate 631 and parallel to the first guide rail 6381, a first rotating shaft 6322 rotatably provided on the angle bracket 612, and a pushing gear 6323 sleeved on the first rotating shaft 6322. The pushing gear 6323 is in meshing transmission with the pushing rack 6321. By adopting the meshing transmission mode of the pushing rack 6321 and the pushing gear 6323, the power of the pushing driving mechanism 632 is efficiently and accurately transmitted to the pushing slide plate 631.

[0037] It can be understood that when the pipe on the material distribution station 613 breaks away from the export inclined shaft 615 and crosses over the apex angle of the angle bracket 612, the pipe will slide back into the pipe storage area 641 again. Therefore, the moving stroke of the pushing slide plate 631 determines the distance between the pushing bar 635 and the apex angle of the angle bracket 612, and the distance between the pushing bar 635 and the apex angle should be determined according to the cross-sectional size of a single pipe. Generally, the distance between the pushing bar 635 and the apex angle should be slightly larger than the width of a single pipe, ensuring the precise separation of the pipes arranged behind during the material distribution process and avoiding the phenomenon of multiple pipes being sent out simultaneously due to improper distance. The moving stroke of the pushing slide plate 631 is controlled by a travel switch assembly. During actual processing, the moving stroke size of the pushing slide plate 631 can be adjusted according to the type and width of the pipes, ensuring the compatibility of the equipment with various specifications of pipes and improving the applicable range and production flexibility of the automatic pipe loading rack 6.

[0038] The first rotating shafts 6322 of two adjacent rack modules 61 are drivingly connected through a first synchronizing shaft 6324, and the first rotating shaft 6322 of one of the rack modules 61 is drivingly connected to a first reduction motor 6325. By using only one first reduction motor 6325, the first rotating shafts 6322 of multiple rack modules 61 can be driven, greatly simplifying the design of the control system, reducing the number of motors required, ensuring the synchronization of all rack modules 61 during the pusher operation, and this high degree of coordination avoids the disorder of pipe conveying caused by non-synchronization, improving the smoothness and efficiency of the entire loading process.

[0039] Furthermore, a second guide rail 6383 perpendicular to the export inclined shaft 615 is provided on the back surface of the lifting slide plate 633, and a second slider 6384 slidably connected to the second guide rail 6383 is fixed on the pusher slide plate 631. The sliding fit of the second guide rail 6383 and the second slider 6384 ensures the precise movement of the lifting slide plate 633 in the vertical direction, avoids tilting or deviation, ensures the stable lifting of the pusher bar 635 and the stacking pusher block 636, and is conducive to accurately screening pipes.

[0040] In this embodiment, the lifting drive mechanism 634 includes a cylinder bracket 6341 provided on the pusher slide plate 631 and a first cylinder 6342 provided on the cylinder bracket 6341. The end of the piston rod of the first cylinder 6342 is drivingly connected to the lifting slide plate 633. When the piston rod of the first cylinder 6342 extends and retracts, it can quickly drive the pusher bar 635 and the stacking pusher block 636 on the lifting slide plate 633 to quickly rise or fall, improving the efficiency and control accuracy of screening pipes and ensuring the smoothness of the production process.

[0041] Specifically, a third guide rail 6385 with the same slope as the export inclined shaft 615 is provided on the back surface of the stacking pusher block 636, and a third slider 6386 slidably connected to the third guide rail 6385 is fixed on the lifting slide plate 633. The design of the third guide rail 6385 having the same slope as the export inclined shaft 615 ensures the linearity and stability of the stacking pusher block 636 during the pushing and stacking operation, and can accurately push the stacked pipes back to the material storage area 641, avoiding accidental deviation or jamming of the pipes. The stacking drive mechanism 637 includes a second cylinder 6371. The cylinder body of the second cylinder 6371 is hinged to the lifting slide plate 633, and the end of the piston rod of the second cylinder 6371 is connected to the third guide rail 6385 through an adapter block 6372, making the stacking drive mechanism 637 compact. When the piston rod of the second cylinder 6371 extends and retracts, it can drive the stacking pusher block 636 to reciprocate towards the material distribution station 613 to push down the stacked pipes, so that the stacked pipes are finally pushed into the material storage area 641. To ensure effective screening and removal of the stacked materials, the second cylinder 6371 should drive the stacking pusher block 636 to reciprocate more than twice.

[0042] In fact, the position of the lifting slide plate 633 at its highest point directly affects the pushing height of the stacking pusher block 636, which is crucial for whether the stacked pipes can be toppled. Therefore, a limit block 6343 is provided at the bottom of the lifting slide plate 633, and a limit screw 6344 is threadedly connected to the limit block 6343 and is oriented towards the bottom surface of the pushing slide plate 631. A scale 6345 extending in the lifting direction of the lifting slide plate 633 is provided on the pushing slide plate 631, and a reading tip 6346 cooperating with the scale 6345 is provided on the lifting slide plate 633. The cooperation between the limit screw 6344 and the limit block 6343 allows the user to precisely adjust the maximum rising position of the lifting slide plate 633 according to the stacking height of the pipes, ensuring that the stacking pusher block 636 can effectively topple the stacked pipes, avoiding pushing failure caused by insufficient height. The combination of the scale 6345 and the reading tip 6346 provides intuitive visual feedback, and the operator can easily read the real-time position of the lifting slide plate 633, simplifying the height adjustment process and improving the operation accuracy and efficiency.

[0043] Preferably, a transition arc surface 616 and transition pulleys 617 located on both sides of the transition arc surface 616 are provided at the top of the guiding inclined bar 614. By providing the transition arc surface 616, it helps the pipes to smoothly transition from the guiding inclined bar 614 to the guiding inclined shaft 615 when flowing into the material distribution station 613, avoiding pipe jamming or scratching caused by sudden angle changes, reducing the collision and friction of the pipes during the guiding process, lowering the risk of surface damage to the pipes, and improving the integrity rate of the pipes. The transition pulleys 617 on both sides play a guiding role, helping the pipes to maintain the correct direction when entering the material distribution station 613, avoiding the pipes deviating from the track or tipping over, enhancing the stability of the pipes when entering the material distribution station 613, and conversely, also helping the pipes in the material distribution station 613 to be screened and smoothly fall back into the material storage area 641.

[0044] In this embodiment, the guiding inclined shaft 615 is inclined downward and chrome-plated, so that a chrome-plated layer is formed on the guiding inclined shaft 615. The chrome-plated layer has the characteristics of being bright, wear-resistant and having a high hardness, and its friction coefficient is small, especially the dry friction coefficient. Whether the pipes are round pipes, square pipes or special-shaped pipes, they can all smoothly slide and complete the transfer. The guiding inclined bar 614 is inclined upward and is made of wear-resistant material to prevent the pipes from rigidly rubbing against the angle frame 612.

[0045] Specifically, the first material blocking assembly 62 includes a third cylinder 621 and a first flip baffle 622 pivotally connected to the angle bracket 612, the piston rod end of the third cylinder 621 is connected to the first flip baffle 622, and the cylinder body of the third cylinder 621 is hinged to the angle bracket 612; under normal working conditions, the piston rod of the third cylinder 621 is extended, and the first flip baffle 622 is in a blocking state, preventing the pipe from sliding forward; when the piston rod of the third cylinder 621 is retracted, the first flip baffle 622 is pulled from the blocking state to the avoidance state, and the action is simple and quick.

[0046] Similarly, the second material blocking assembly 65 includes a fourth cylinder 652 and a second flip baffle 651 pivotally connected to the angle bracket 612, the piston rod end of the fourth cylinder 652 is connected to the second flip baffle 651, and the cylinder body of the fourth cylinder 652 is hinged to the angle bracket 612; under normal working conditions, the piston rod of the fourth cylinder 652 is extended, and the second flip baffle 651 is in a blocking state, preventing the pipe from sliding forward. When the piston rod of the fourth cylinder 652 is retracted, the second flip baffle 651 is pulled from the blocking state to the avoidance state, and the action is simple and quick.

[0047] The automatic continuous pipe cutting system controls the operation of all mechanisms through the pipe cutting control system. The angle frame 612 is provided with a first sensor 661 for detecting whether there are pipes at the material distribution station 613 and a second sensor 662 for detecting whether there are pipes at the material feeding station 653. The first sensor 661 and the second sensor 662 automatically detect whether there are pipes at the material distribution station 613 and the material feeding station 653, and feedback signals to the pipe cutting control system, so that the material feeding work can be carried out in an orderly manner intelligently.

[0048] A positioning reference plate 67 is provided on the outer side of the leftmost rack module 61 , and one end of the pipe can be pressed against the positioning reference plate 67 to achieve positioning.

[0049] For details, see Figure 1 and Figure 9 As shown, the side bracket 1 includes an upper longitudinal beam 11, a lower longitudinal beam 13 arranged below the upper longitudinal beam 11 and parallel to the upper longitudinal beam 11, a plurality of vertical beams 12 connecting the upper longitudinal beam 11 and the lower longitudinal beam 13, and a support 14 fixed to the lower longitudinal beam 13 and the vertical beam 12. The vertical beams 12 are arranged at intervals. The side of the upper longitudinal beam 11 is penetrated by a dust exhaust port 15 facing the laser cutting component 3, and the dust exhaust port 15 is connected to the exhaust pipe of the exhaust dust removal mechanism. During the cutting process, when the exhaust dust removal mechanism is started, the airflow in the cutting area is sucked into the dust exhaust port 15 by negative pressure, thereby sucking the metal dust generated during the laser cutting process, effectively reducing the spread of dust in the workshop, improving the working environment, and protecting the health of operators.

[0050] In this embodiment, the centering support mechanism 8 is arranged on the support 14, and a variable-diameter wheel support mechanism 9 for supporting the pipe in a follow-up manner is also arranged on the support 14. The centering support mechanism 8 and the variable-diameter wheel support mechanism 9 are both prior arts and will not be elaborated here.

[0051] See Figure 9 As shown, the laser cutting assembly 3 includes an X-axis sliding mechanism 31 arranged on the gantry 2, a transverse sliding bracket 32 arranged on the X-axis sliding mechanism 31, a Z-axis sliding mechanism 33 arranged on the longitudinal sliding bracket, a vertical sliding bracket 34 arranged on the Z-axis sliding mechanism 33, and a laser cutting head 35 arranged at the bottom of the vertical sliding bracket 34. The laser cutting head 35 can move flexibly and quickly under the drive of the X-axis sliding mechanism 31 and the Z-axis sliding mechanism 33 to perform straight cutting on the pipe.

[0052] A Y-axis guide rail 16 extending in the front-rear direction is arranged on the upper longitudinal beam 11. The front chuck assembly 5 includes a first side sliding plate 51, a front chuck body 52 arranged on the first side sliding plate 51, and a displacement cylinder 53 fixed on the side hanging bracket 1. The first side sliding plate 51 is slidably connected to the Y-axis guide rail 16 through a Y-axis slider, and the displacement cylinder 53 is drivingly connected to the first side sliding plate 51 to drive the front chuck body 52 to be located in front of or behind the laser cutting assembly 3. It can be understood that when the length of the pipe fitting is reduced after slitting processing, due to the limitation of the combined clamping of the rear chuck assembly 4 and the front chuck assembly 5, there will still be a relatively long tail stock, which is difficult to further cut. Then the front chuck body 52 releases the pipe, the laser cutting assembly 3 rises, and the displacement cylinder 53 drives the front chuck body 52 on the first side sliding plate 51 to move to the front of the laser cutting head 35, so that the rear chuck assembly 4 can continue to move forward and approach the laser cutting assembly 3 without being blocked by the front chuck assembly 5. At this time, the laser cutting assembly 3 is located between the front chuck assembly 5 and the rear chuck assembly 4, and the laser cutting assembly 3 further cuts the tail stock, thereby realizing short tail stock cutting.

[0053] In this embodiment, the rear chuck assembly 4 includes a second side sliding plate, a rear chuck body arranged on the second side sliding plate, a Y-axis driving motor arranged on the second side sliding plate, and a first gear arranged on the output end of the Y-axis driving motor. The second side sliding plate is slidably connected to the Y-axis guide rail 16 through a Y-axis slider. A Y-axis rack 17 extending in the front-rear direction is arranged on the upper longitudinal beam 11, and the first gear is in meshing transmission with the Y-axis rack 17. Driven by the Y-axis driving motor, the rear chuck body on the second side sliding plate can smoothly move horizontally and stably clamp the tail of the pipe fitting to achieve movement.

[0054] Specifically, see Figure 1 and Figure 8As shown, the material receiving frame 7 includes a T-shaped support plate 71 fixed on the side hanging frame 1, a first material receiving plate 72, a second material receiving plate 73 hinged to the first material receiving plate 72, a lifting vertical plate 74 fixed to the bottom of the first material receiving plate 72, a lifting rack 75 and a lifting guide rail 76 vertically arranged on the lifting vertical plate 74, and a material unloading cylinder 77 arranged on the lifting vertical plate 74, the piston rod end of the material unloading cylinder 77 is hinged to the second material receiving plate 73 through a joint, the T-shaped support plate 71 is located below the first material receiving plate 72, the T-shaped support plate 71 is provided with a fixed slider 78 slidably connected to the lifting guide rail 76, the T-shaped support plate 71 is provided with a lifting driver 79, and the output end of the lifting driver 79 is provided with a transmission gear meshing with the lifting rack 75.

[0055] The lifting driver 79 drives the transmission gear to rotate, thereby driving the lifting rack 75, the lifting vertical plate 74 and the lifting guide rail 76 to move up and down as a whole. Under the limit guidance of the lifting guide rail 76 and the fixed slider 78, it is ensured that the lifting vertical plate 74 maintains a vertical movement direction, thereby driving the first material receiving plate 72 and the second material receiving plate 73 on the lifting vertical plate 74 to move up and down. When the first material receiving plate 72 and the second material receiving plate 73 are in the material receiving state, the first material receiving plate 72 and the second material receiving plate 73 are spliced ​​to form a material receiving plane parallel to the horizontal plane. The lifting height can be dynamically raised and lowered according to the data of the pipe or fixed at a suitable height. The optimal material receiving height is that the material receiving plane just supports the bottom of the pipe. The cut pipe sections cut by the pipe cutting machine fall directly on the second material receiving plate 73 to reduce the collision and impact between the cut pipe sections and the material receiving frame 7. Then the unloading cylinder 77 drives the second material receiving plate 73 to flip downward to form an angle with the horizontal plane, so that under the action of gravity, the short pipe sections on the second material receiving plate 73 slide downward along the second material receiving plate 73 to the finished product storage tray to realize unloading.

[0056] In this embodiment, the lifting driver 79 includes a reducer 791 and a driving motor 792, the output end of the driving motor 792 is in transmission connection with the input end of the reducer 791, and the transmission gear is arranged on the output end of the reducer 791. By using the driving motor 792 as the driving source, the driving motor 792 automatically controls the components on the lifting vertical plate 74 to move up and down under the control of the control system, and dynamically adjusts the distance between the second receiving plate 73 and the pipe material, so that the second receiving plate 73 can avoid the rotation of the cut pipe section, and the second receiving plate 73 can also abut against the bottom surface of the cut pipe section to connect the pipe material after the pipe material is cut.
