Description

Technical Field

[0001] The invention relates to the technical field of steel pipe cutting, and in particular to a cutting device for producing seamless steel pipes. Background Art

[0002] Steel pipe cutting is an important part of steel pipe processing. Its main purpose is to accurately cut the steel pipe according to the predetermined size to meet different engineering and process requirements. Steel pipe cutting is not only related to the utilization rate of materials, but also affects the quality and production efficiency of the final product. Therefore, it is crucial to choose the right cutting method and equipment. There are various methods for steel pipe cutting, mainly including manual cutting, mechanical cutting, flame cutting, plasma cutting, etc. The most commonly used method is mechanical cutting, which uses special mechanical equipment for cutting, such as steel pipe cutting machines, band saws, etc. Mechanical cutting has high efficiency and high precision, and is suitable for batch cutting and large steel pipe cutting.

[0003] A Chinese patent with authorization announcement number CN116140690B discloses a fixed-length cutting device for the production of small-diameter steel pipes, including: a positioning plate, the positioning plate is vertically connected to a mounting beam, a cutting machine is arranged on the mounting beam; a mounting groove is arranged on the side wall of the mounting cylinder, and a fixing part is arranged on the inner wall of the mounting cylinder; wherein, the elastic telescopic rod is adapted to the mounting beam, and the positioning plate is adapted to the mounting cylinder. The patent firstly rotates the motor to drive the cutting piece to cut, and first cuts the pipe body located on the front side. After cutting, the cutting piece is controlled to reverse and cut the pipe body on the rear side, thereby realizing fixed-length cutting of the small-diameter steel pipe; the cut pipe body is located on a buffer mechanism, thereby realizing the reception of the cut small-diameter steel pipe, and the connecting shaft is driven to rotate through a conveyor belt, so that the dividing plate rotates, thereby realizing the classified discharge of the cut small-diameter steel pipe.

[0004] When batch processing steel pipes, because the number of single cuts is large, more chips will fall into the gaps between adjacent steel pipes, and as the cutting time increases, the closer the steel pipe is to the bottom, the more chips there are in the gap. During the saw cutting process, not only will the saw wear be aggravated, but the chips will also affect the cutting effect of the steel pipe end face, resulting in cuts or burrs on the steel pipe end face, reducing the dimensional accuracy of the steel pipe. Summary of the invention

[0005] The present invention provides a cutting device for seamless steel pipe production, aiming to solve the technical problems in the related art that when batch processing steel pipes, due to a large number of single cuts, a large amount of chips will fall into the gaps between adjacent steel pipes. Moreover, as the cutting time increases, the more chips there are in the gaps of the steel pipes closer to the bottom. During the cutting process of the saw blade, it will not only increase the wear of the saw blade, but also the chips will affect the cutting effect of the end face of the steel pipe, resulting in cut marks or burrs on the end face of the steel pipe, reducing the dimensional accuracy of the steel pipe.

[0006] A cutting device for seamless steel pipe production according to the present invention includes: a base, a positioning module and a cutting module provided on the base. The cutting module includes a cutting frame vertically slidably assembled on the base, a driving wheel provided on the cutting frame, and a saw blade. A cleaning module is also provided on the cutting frame; the cleaning module includes two mounting seats fixed to the front side of the cutting frame on the left and right. A connecting plate is vertically elastically slidably connected inside the mounting seat. A through hole is provided at the rear side of the connecting plate, and a pushing plate is provided on the mounting seat at a position corresponding to the through hole; a front bearing seat and a rear bearing seat are vertically slidably matched inside the mounting seat. The front bearing seat and the rear bearing seat are vertically elastically slidably connected, and the through hole corresponds to the rear bearing seat. The front bearing seat has through avoiding long holes on both sides. A cleaning roller is rotatably installed inside the front bearing seat. The two sides of the cleaning roller are provided with rotating shafts passing through the avoiding long holes through a one-way rotation structure. A rotating seat elastically connected to the front bearing seat is rotatably installed on the rotating shafts. The rear bearing seat has an abutting portion for pushing the rotating seat to slide forward and a material pushing portion for pushing the cut steel pipe forward. A transmission structure for driving the rotating shaft to rotate is provided between the rotating shaft on one side and the mounting seat. A sliding seat slides back and forth inside the front bearing seat, and a power storage member connected to the cleaning roller is provided on the sliding seat.

[0007] Beneficial effects: As the saw blade cuts downward, the cleaning roller remains in place, causing the connecting spring to be compressed. The cleaning roller abuts against the steel pipe, which can ensure the stability of the cut part and prevent it from being pulled by the saw blade. After the steel pipe falls, the connecting spring will quickly release its elastic force, causing the connecting plate to push the rear bearing seat and the front bearing seat downward. During this process, the rear bearing seat and the front bearing seat complete their reset. The reset spring pushes the rotating shaft and the cleaning roller to move backward and reset. After the rotating shaft moves to the rear side, the gear meshes with the rack, and the gear drives the rotating shaft to rotate. At this time, the rotating shaft will drive the cleaning roller to rotate together and store power for the power storage member at the same time. When the cleaning roller reaches the lowest position, the gear reaches below the rack and disengages from it. Then the power storage member releases its elastic force to drive the cleaning roller to rotate. The cleaning roller can clean the debris that has fallen between two adjacent steel pipes on the left and right. In this way, the cutting of all steel pipes is completed in a cycle. When the steel pipe is almost cut through, the cleaning roller abuts against the steel pipe, preventing the steel pipe from being directly torn off the almost cut part due to the pulling of the saw blade, thus avoiding the steel pipe from being thrown out and the cut end face from being uneven. At the same time, it can clean the debris between two adjacent steel pipes, effectively improving the cutting effect of the end face of the steel pipe.

[0008] Preferably, through holes penetrating left and right are provided near the bottom of the mounting seat, connecting springs are arranged in the through holes, the connecting springs are arranged vertically, and the lower ends of the connecting springs are fixedly connected with the connecting plates, and the bottoms of the connecting plates abut against the upper surfaces of the front bearing seat and the rear bearing seat.

[0009] The effect is that the through holes can ensure that both ends of the front bearing seat and the rear bearing seat penetrate, so that the bottom of the connecting plate abuts against the upper surfaces of the front bearing seat and the rear bearing seat.

[0010] Preferably, the lower end of the pushing plate extends into the through hole of the mounting seat, the pushing plate is slidably matched with the mounting seat, a fixing hole is arranged on the pushing plate, and a jack is arranged at a position corresponding to the fixing hole on the mounting seat.

[0011] The effect is that the pushing plate can move up and down to adjust the length penetrating into the through hole, so as to adjust the distance that the rear bearing seat moves after being pushed.

[0012] Preferably, the pushing part is of a right-angled triangle structure, the pushing part is horizontally arranged in the left-right direction, the pushing part has two adjacent right-angled faces and an inclined face, the two adjacent right-angled faces are respectively located above and at the rear side, its inclined face is located at the front side, and the inclined face gradually slopes downward from front to back.

[0013] The effect is that the pushing part can be inserted downward into the gap formed after the steel pipe is cut, so as to push the cut steel pipe forward and make it fall off.

[0014] Preferably, the one-way rotation structure is a one-way gear.

[0015] Preferably, the energy storage member is a coil spring installed on the sliding seat, one end of the coil spring is connected with the sliding seat, and the other end of the coil spring is connected with the cleaning roller.

[0016] The effect is that the coil spring can store energy, and when the cleaning roller reaches the lower side, the coil spring drives the cleaning roller to rotate.

[0017] Preferably, the rotating seat is of a square structure, a reset spring extending in the front-rear direction is fixedly connected to the rotating seat, and the end of the reset spring far away from the rotating seat is connected with the front bearing seat.

[0018] Preferably, a discharge rack is fixedly installed on the front side of the base, and an adjusting plate is slidably installed on the discharge rack in the left-right direction.

[0019] Preferably, two fixing plates are arranged at intervals in the left-right direction on the cutting rack, grooves penetrating left and right are formed at the bottoms of the fixing plates, and the saw blade passes through the grooves of the two fixing plates, and the mounting seat is fixedly arranged on the fixing plates.

[0020] Preferably, a conveying rack is provided at the rear side of the base, and a plurality of rotating rollers are arranged on the conveying rack at intervals in the front-rear direction and rotating about an axis in the left-right direction.

[0021] With the above technical solution, the beneficial effects of the present invention are as follows: As the saw blade cuts downwards, the cleaning roller remains in place, causing the connecting spring to be compressed. The cleaning roller abuts against the steel pipe, which can ensure the stability of the cut part and prevent it from being pulled by the saw blade. After the steel pipe falls, the connecting spring will quickly release its elastic force, causing the connecting plate to push down the rear bearing seat and the front bearing seat. During this process, the rear bearing seat and the front bearing seat are reset, and the reset spring pushes the rotating shaft and the cleaning roller to move backward and reset. After the rotating shaft moves to the rear side, the gear meshes with the rack, and the gear drives the rotating shaft to rotate. At this time, the rotating shaft will drive the cleaning roller to rotate together and simultaneously charge the energy storage member. When the cleaning roller reaches the lowest position, the gear reaches below the rack and disengages from it, and then the energy storage member releases its elastic force to drive the cleaning roller to rotate. The cleaning roller can clean the debris falling between two adjacent steel pipes on the left and right. In this way, the cutting of all steel pipes is completed in a cycle. When the steel pipe is almost cut through, the cleaning roller abuts against the steel pipe, preventing the steel pipe from being pulled by the saw blade and directly tearing off the almost cut part, thus avoiding the steel pipe from being thrown out and the cut end face being uneven. At the same time, it can clean the debris between two adjacent steel pipes, effectively improving the cutting effect of the steel pipe end face. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0034] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings. The embodiments described below by referring to the drawings are exemplary and are intended to explain the present invention, and should not be construed as a limitation to the present invention.

[0035] As Figures 1 to 11 shown, a specific embodiment of a cutting device for seamless steel pipe production according to the present invention includes a bearing module, a positioning module, a cutting module, a blanking module and a cleaning module.

[0036] As Figure 1 and Figure 2 shown, the bearing module includes a base 10, a bracket 11, a conveying rack 30 and a rotating roller 31.

[0037] The base 10 is of a rectangular structure, and the length direction extends along the left-right direction. The bracket 11 is fixedly installed on the upper surface of the base 10, and the bracket 11 is of an L-shaped structure. The conveying rack 30 is installed at the rear side of the base 10. The conveying rack 30 is also of a rectangular structure, and the length direction of the conveying rack 30 extends along the front-rear direction. A plurality of rotating rollers 31 are arranged at intervals along the front-rear direction on the conveying rack 30. The axis of the rotating roller 31 extends along the left-right direction, and the rotating roller 31 can convey the steel pipe.

[0038] The positioning module includes a vertical positioning unit and a horizontal positioning unit.

[0039] As Figure 2As shown, the vertical positioning unit includes a clamping cylinder 12 fixedly mounted on the upper surface of the bracket 11, and a pressing plate 13 is fixedly mounted on the telescopic portion of the clamping cylinder 12. The clamping cylinder 12 can drive the pressing plate 13 to move up and down, thereby clamping and positioning the steel pipe in the vertical direction.

[0040] like Figure 3 As shown, the horizontal positioning unit includes a positioning plate 14 mounted on the base 10 for horizontal sliding along the left-right direction, and the positioning plate 14 corresponds to the vertical surface of the bracket 11. A positioning cylinder 15 is fixedly mounted on the base 10, and the telescopic part of the positioning cylinder 15 is fixedly connected to the positioning plate 14, so that the positioning plate 14 can be driven to slide horizontally, and the steel pipe can be clamped on the vertical surface of the bracket 11. The steel pipe is positioned by the clamping and positioning of the steel pipe in the vertical direction by the pressing plate 13 and the clamping and positioning of the steel pipe in the horizontal direction by the positioning plate 14.

[0041] like Figure 1 , Figure 2 , Figure 4 As shown, the cutting module includes a slide column 40 , a cutting frame 41 , a lifting cylinder 42 , a carrying box 43 , a driving wheel 44 , a saw blade 45 and a fixing plate 46 .

[0042] A sliding column 40 is fixedly installed on the base 10, and the sliding column 40 is vertically arranged. A cutting frame 41 is vertically slidably installed on the sliding column 40. A lifting cylinder 42 is also fixedly installed on the base 10. The telescopic part of the lifting cylinder 42 is fixedly connected to the cutting frame 41. The lifting cylinder 42 is used to drive the cutting frame 41 to rise and fall along the sliding column 40.

[0043] The cutting frame 41 is symmetrically provided with a carrying box 43 on both sides. The carrying box 43 is fixedly connected to the cutting frame 41, and the two carrying boxes 43 are tilted. In this embodiment, the carrying boxes 43 gradually tilt upward from front to back. The two carrying boxes 43 are rotatably mounted with driving wheels 44, one of which is driven by a motor. The saw blade 45 is transmission-mounted on the outside of the two driving wheels 44, so that when the two driving wheels 44 rotate, the saw blade 45 can be driven to rotate, and at the same time, the lifting cylinder 42 drives the cutting frame 41 to rise and fall, thereby completing the cutting of the steel pipe.

[0044] Two fixing plates 46 are arranged at intervals along the left-right direction on the cutting frame 41, and the two fixing plates 46 are fixedly mounted on the cutting frame 41. A square groove is provided at the bottom of each fixing plate 46, and the groove is through the left and right sides, and the saw blade 45 passes through the grooves of the two fixing plates 46, which can limit the saw blade 45, improve the stability of the saw blade 45 when cutting, and at the same time, keep the part cut by the saw blade 45 in a vertical state, that is, the part of the saw blade 45 located between the left and right fixing plates 46 is in a vertical state. It is particularly emphasized that the above structure and principle belong to the prior art and will not be elaborated here.

[0045] Continue to return to Figure 1 The blanking module includes a discharge rack 20 fixedly installed on the front side of the base 10. The discharge rack 20 is of a U-shaped structure and has a bottom plate and two vertical plates. The bottom plate of the discharge rack 20 is inclined, and the bottom plate slopes upward gradually from front to back, so as to facilitate the discharged steel pipes cut off to be discharged outside the device. The two vertical plates are distributed at intervals in the left-right direction, and each vertical plate is vertically arranged. The vertical plates can play a role in blocking to prevent the steel pipes during the cutting process from being thrown out.

[0046] An adjusting plate 21 is slidably installed on the discharge rack 20 in the left-right direction. The adjusting plate 21 is slidably matched with the bottom plate of the discharge rack 20, and bolts for fixing the adjusting plate 21 are provided on the discharge rack 20, so that the position of the adjusting plate 21 can be moved left and right to adapt to different numbers of steel pipes.

[0047] The cleaning module includes a carrying unit and a cleaning unit. The carrying unit includes a mounting seat 50, a connecting spring 51, a connecting plate 52 and a pushing plate 54.

[0048] As Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 and Figure 9 shown, there are two mounting seats 50, which are respectively fixedly installed on the front sides of the two fixing plates 46, and the two mounting seats 50 are horizontally arranged in the left-right direction. Through holes penetrating left and right are provided at positions near the bottom of the two mounting seats 50, and connecting springs 51 are arranged in the through holes. The connecting springs 51 are vertically arranged. The upper ends of the connecting springs 51 are fixedly connected to the top walls of the through holes, and the lower ends of the connecting springs 51 are fixedly provided with a connecting plate 52. The connecting plate 52 slides up and down in the through hole. A through hole 53 penetrating up and down is provided in the middle and near the rear side of the connecting plate 52.

[0049] A pushing plate 54 is vertically slidably installed in each mounting seat 50, and the lower end of the pushing plate 54 extends into the through hole. The pushing plate 54 has a handle, and there is an opening on the front side of the mounting seat 50. The handle of the pushing plate 54 passes through the opening on the mounting seat 50 and extends to the outside, so as to facilitate manually adjusting the height of the pushing plate 54. Fixing holes 55 are provided on the pushing plate 54, and a plurality of jacks 56 are vertically spaced on the front side of the mounting seat 50. By manually adjusting the position of the pushing plate 54, the fixing holes 55 are made to correspond to the jacks 56, and then the pins are passed through the jacks 56 and into the fixing holes 55 to fix the pushing plate 54.

[0050] As Figure 6 、 Figure 7 、 Figure 8 、 Figure 9 、 Figure 10 and Figure 11As shown, the cleaning unit includes a rear bearing seat 60, a material pushing part 61, an abutting part 62, a front bearing seat 70, a supporting part 71, a cleaning roller 73, a rotating shaft 74, a rotating seat 75, a reset spring 76, a side plate 77, a gear 80, a rack 81, a sliding seat 82, and an energy storage part 83.

[0051] On the inner sides of the two mounting seats 50, there are arranged a rear bearing seat 60 and a front bearing seat 70, both of which are slidably fitted in the through holes of the two mounting seats 50. The rear bearing seat 60 is located at the rear side of the front bearing seat 70, and the two are vertically elastically slidably fitted, and they are slidably fitted up and down in the manner of a slider and a chute. At the same time, a spring (not shown in the figure) is arranged between them.

[0052] Supporting parts 71 are arranged on the left and right sides of both the rear bearing seat 60 and the front bearing seat 70, and the supporting parts 71 are all rectangular structures. The upper surfaces of the rear bearing seat 60 and the front bearing seat 70 are flush, and the upper surfaces of the supporting parts 71 of the two are also in a flush state. The supporting parts 71 on both sides of the rear bearing seat 60 and the front bearing seat 70 respectively penetrate into the through holes of the two side mounting seats 50. That is, the supporting parts 71 on the left side of the rear bearing seat 60 and the front bearing seat 70 all penetrate into the through hole of the left mounting seat 50, and the supporting parts 71 on the right side of the rear bearing seat 60 and the front bearing seat 70 all penetrate into the through hole of the right mounting seat 50.

[0053] The supporting parts 71 are all vertically slidably fitted with the through holes of the mounting seats 50. That is, the supporting parts 71 on the rear bearing seat 60 are in contact with and slidably fitted with the rear side wall of the through hole of the mounting seat 50, and the front bearing seat 70 is in contact with and slidably fitted with the front side wall of the through hole of the mounting seat 50, so as to ensure the stability of the rear bearing seat 60 and the front bearing seat 70, and enable them to only move up and down.

[0054] In the initial state, the connecting spring 51 is in a released state, and the lower surface of the connecting plate 52 abuts against the upper surface of the supporting part 71 to fix the rear bearing seat 60 and the front bearing seat 70 to prevent them from shaking.

[0055] A material pushing part 61 is arranged at the bottom of the rear bearing seat 60. The material pushing part 61 is a right-angled triangle structure, and the material pushing part 61 is horizontally arranged in the left-right direction. The material pushing part 61 has two adjacent right-angled surfaces and an inclined surface. The two adjacent right-angled surfaces are respectively located above and at the rear side, and its inclined surface is located at the front side, and the inclined surface slopes downward gradually from front to back.

[0056] Abutting parts 62 are arranged on the left and right sides of the rear bearing seat 60. The front side of the abutting part 62 is an inclined surface, and the inclined surface of the abutting part 62 slopes downward gradually from front to back.

[0057] Avoidance long holes 72 that penetrate left and right are opened on the left and right side walls of the front bearing seat 70. The avoidance long holes 72 are strip-shaped structures, and their length directions extend in the front-rear direction (such asFigure 11 ). A cleaning roller 73 is rotatably installed inside the front bearing seat 70. The axis of the cleaning roller 73 is horizontally arranged in the left - right direction, and the cleaning roller 73 is covered with bristles. In this embodiment, the bristles are made of nylon.

[0058] It should be particularly emphasized that the lower end of the material pushing part 61 is higher than the horizontal plane where the axis of the cleaning roller 73 is located, so as to reserve enough space for the descent of the material pushing part 61.

[0059] Rotating shafts 74 are arranged on both the left and right sides of the cleaning roller 73. The rotating shafts 74 are connected to the cleaning roller 73 through one - way rotating structures (not shown in the figure). The one - way rotating structures are one - way gears, and the rotating shafts 74 on both sides respectively pass through the avoidance long holes 72 on the left and right sides. It should be particularly emphasized that the height of the avoidance long holes 72 is the same as the diameter on the rotating shafts 74, so that the rotating shafts 74 can slide back and forth in the avoidance long holes 72.

[0060] Rotating seats 75 are rotatably installed on the rotating shafts 74 on both the left and right sides. The rotating seats 75 can rotate around the axis of the rotating shafts 74. In this embodiment, the rotating seats 75 are square structures. Reset springs 76 are arranged on the front sides of the rotating seats 75. Side plates 77 are fixedly arranged on both sides of the front bearing seat 70. One end of the reset spring 76 away from the rotating seat 75 is fixedly connected to the side plate 77 on this side.

[0061] When the rear bearing seat 60 descends along the front bearing seat 70, the inclined surface of the abutting part 62 of the rear bearing seat 60 will push the rotating seat 75, causing the rotating seat 75 to drive the cleaning roller 73 to slide forward. At this time, the reset spring 76 will be compressed. When the rear bearing seat 60 rises and resets, the reset spring 76 releases, causing the cleaning roller 73 to slide backward and reset.

[0062] A gear 80 is arranged on the rotating shaft 74 on the right side, and a rack 81 is arranged at a position corresponding to the gear 80 in the through - hole on the right - hand mounting seat 50. In the initial state, the gear 80 is located below the rack 81 and the two are not meshed.

[0063] As Figure 8 shown, a sliding seat 82 is slidably installed on the inner right - hand side wall of the front bearing seat 70 in the front - rear direction. The sliding seat 82 has an opening for the rotating shaft 74 to pass through. A power - storing member 83 is arranged on the sliding seat 82. In this embodiment, the power - storing member 83 is a torsion spring, and one end of the torsion spring is connected to the sliding seat 82 and the other end is connected to the cleaning roller 73. When the rotating shaft 74 drives the cleaning roller 73 to rotate, the torsion spring can be wound up.

[0064] During operation, multiple rows of vertically stacked steel pipes are sent to the inner side of the support 11 through the conveying frame 30. The steel pipes are positioned by clamping and positioning them vertically through the pressing plate 13 and horizontally through the positioning plate 14. Then, the lifting cylinder 42 drives the cutting frame 41 to descend, and the saw blade 45 starts to cut the steel pipes. When the saw blade 45 touches the steel pipe, the cleaning roller 73 also abuts against the steel pipe at this time. As the saw blade 45 cuts downward, the cleaning roller 73 will stay in place. As the mounting seat 50 continues to descend, the connecting plate 52 abuts against the supporting portion 71, causing the connecting spring 51 to be compressed. The cleaning roller 73 abuts against the steel pipe, which can ensure the stability of the cut part and prevent it from being pulled by the saw blade 45. That is, when the steel pipe is almost cut through, it can prevent the steel pipe from being pulled by the saw blade 45 and directly tearing off the almost cut part, which would cause the steel pipe to be thrown out and the end face to be uneven. During the descent of the mounting seat 50, the gear 80 meshes with the rack 81, causing the rotating shaft 74 to rotate. However, since the rotating shaft 74 is connected to the cleaning roller 73 through a one-way rotating structure, the rotating shaft 74 will not drive the cleaning roller 73 to rotate at this time.

[0065] When the saw blade 45 is about to finish cutting a row of steel pipes being cut, the pushing plate 54 will pass through the through-hole 53 and abut against the rear bearing seat 60, thereby pushing the rear bearing seat 60 to descend. The rear bearing seat 60 will descend along the front bearing seat 70. When the abutting portion 62 on the rear bearing seat 60 abuts against the rotating seat 75, the row of steel pipes being cut is just cut off. As the saw blade 45 continues to descend and starts to cut the next row of steel pipes, it will cause the rear bearing seat 60 to descend, and the abutting portion 62 will push the rotating seat 75 to slide forward. The rotating seat 75 drives the cleaning roller 73 to slide forward, and the cleaning roller 73 will push the cut-off part at the front end of the steel pipe forward. At the same time, the pushing portion 61 will also be inserted into the gap at the cutting position of the steel pipe, and the inclined surface on the front side of the pushing portion 61 will also push the cut-off part at the front end of the steel pipe forward until the cut-off steel pipe is pushed off. It should be noted that when the saw blade 45 continues to descend and starts to cut the next row of steel pipes, since the debris falls into the gap between the two steel pipes, the saw blade 45 needs to cut to a certain depth before it contacts the debris. The saw blade 45 does not contact the debris when it first starts cutting the steel pipe.

[0066] After the steel pipe falls, the connecting spring 51 will quickly release its elastic force, causing the connecting plate 52 to push downwards, and then pushing the rear bearing seat 60 and the front bearing seat 70. During this process, the rear bearing seat 60 and the front bearing seat 70 are reset, that is, the rear bearing seat 60 will rise relative to the front bearing seat 70. The reset spring 76 pushes the rotating shaft 74 and the cleaning roller 73 to move backward for reset. After the rotating shaft 74 moves to the rear side, the gear 80 meshes with the rack 81, and the gear 80 drives the rotating shaft 74 to rotate. At this time, the rotation of the rotating shaft 74 will drive the cleaning roller 73 to rotate together, and at the same time, the energy storage member 83 is charged. When the cleaning roller 73 reaches the lowest position, that is, the cleaning roller 73 abuts against a row of steel pipes being cut, the gear 80 reaches below the rack 81 and disengages from it, and then the energy storage member 83 releases its elastic force, driving the cleaning roller 73 to rotate. The cleaning roller 73 can clean the debris that has fallen between two adjacent steel pipes on the left and right. In this cycle, the cutting of all steel pipes is completed.
