A seamless steel pipe cutting device

Abstract

This invention provides a seamless steel pipe cutting device, comprising: a frame, a clamping mechanism, a mounting base, an abutment base, a cutting mechanism, a control mechanism, a deburring mechanism, and a driving mechanism. After the cutting mechanism completes the cutting, the control mechanism applies a force that moves the two abutment bases away from each other, pushing the two cut seamless steel pipe segments to separate along the axial direction. After the two steel pipe segments are separated, the two deburring mechanisms mounted on the mounting base abut against the inner and outer sides of the cut ends of the two steel pipe segments respectively. The driving mechanism then drives the abutment bases to rotate around the steel pipe, realizing the annular deburring of the deburring mechanism. This rotational linkage design can completely remove burrs from the inner and outer sides of the cut, avoiding manual repair and improving the end processing quality. The entire process, through the coordinated action of each mechanism, forms an integrated operation process of clamping and positioning, precise cutting, end separation, and comprehensive deburring.

Description

Technical Field

[0001] This invention relates to the field of seamless steel pipe cutting technology, and more specifically to a seamless steel pipe cutting device. Background Technology

[0002] Seamless steel pipes are made from a single piece of metal and have no seams on their surface. They are mainly used as oil and gas drilling pipes, cracking pipes for petrochemicals, boiler tubes, bearing tubes, and high-precision structural steel pipes for automobiles, tractors, and aviation. They are widely used in the manufacture of structural components and mechanical parts.

[0003] Currently, seamless steel pipes are generally cut using a cutting device during processing.

[0004] However, in the existing technology, when cutting seamless steel pipes with a cutting disc, due to the high-speed rotation cutting characteristics of the cutting disc, the toughness of the steel pipe material, and the lack of effective edge restraint and grinding mechanism during the cutting process, burrs are easily generated on the end face of the cut steel pipe, and the flatness of the end face is poor. These defects not only affect the subsequent assembly accuracy of the seamless steel pipe, but may also cause safety hazards during handling or processing, becoming a key technical problem restricting the cutting quality of seamless steel pipes and the efficiency of subsequent processes.

[0016] Compared with the prior art, the present invention has at least the following advantages: 1. In this invention, the entire process is integrated into a single operation flow through the coordinated action of various mechanisms, including clamping and positioning, precise cutting, separation of ports, and comprehensive deburring. This significantly improves processing efficiency and precision while reducing manual intervention and ensuring the stability of processing quality.

[0017] 2. In this invention, the meshing transmission between the gear ring and the drive gear ensures high rotational accuracy and stable torque transmission, enabling the rotating seat to operate at a uniform speed. This not only ensures a regular cutting trajectory and a smooth cut, but also achieves comprehensive and uniform deburring. At the same time, the single power source design driven by the first motor simplifies the transmission chain and reduces the failure rate of the mechanism. The coaxial layout of the ring part and the seamless steel pipe further avoids processing errors caused by rotational offset, thus improving the overall processing quality.

[0018] 3. In this invention, the extension action of the active telescopic component achieves precise control of the contact of the abutment seat, and remains stationary after cutting to avoid interfering with the release of force of the elastic telescopic component. The storage and release of force of the elastic telescopic component not only plays a buffering role to avoid damage to the steel pipe or the abutment seat by rigid contact, but also provides sufficient power for the separation of the abutment seat.

[0019] 4. In this invention, the threaded transmission between the lead screw and the nut seat, and the meshing transmission between the control rack and the control gear ensure that the inner blade rotates smoothly and at a precise angle until the inner blade fits against the inner wall of the steel pipe, so that the V-shaped structure can adapt to the thickness of the seamless steel pipe; the V-shaped blade structure can fully cover the burrs on the inside and outside of the port, and in conjunction with the rotation around the pipe, it greatly improves the comprehensiveness and uniformity of deburring. The coordinated action and transmission of the whole effectively ensure the stability and processing quality of the deburring operation.

[0020] 5. In this invention, the contact between the inner blade and the inner wall of the slot enables precise triggering and locking of the spiral spring's energy storage, preventing premature release of the stored energy. The meshing transmission of the transmission rack and gear ensures a stable transition from the sliding action of the contact seat to the energy storage action. The energy storage and release of the spiral spring provide reliable power for the rotation of the lead screw. The sliding connection between the square rod and the lead screw not only ensures power transmission but also adapts to the sliding stroke of the extended housing. The coordinated operation of the entire transmission chain makes the energy storage, locking, release, and subsequent inner blade rotation and positioning actions smooth and controllable, further improving the accuracy and consistency of the deburring mechanism's actions and laying the foundation for stable and efficient deburring operations.

[0021] 6. In this invention, after the seamless steel pipe is transported to the cutting station, two opposing clamping components synchronously approach the seamless steel pipe. The clamping seat of each clamping unit slides radially towards the steel pipe along the annular seat until multiple clamping rollers are in close contact with the outer wall of the seamless steel pipe. The sliding distance of the clamping seat can be adjusted according to the diameter of the steel pipe so that the clamping rollers can be adapted to steel pipes of different specifications. At the same time, multiple clamping rollers distributed in a circular array uniformly wrap around the steel pipe from the circumference to achieve stable centering clamping. The clamping rollers can effectively restrict the seamless steel pipe from rotating in the circumferential direction and can slide in the axial direction. Attached Figure Description

[0029] The embodiments of the technical solution of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the technical solution of the present invention and are therefore intended to limit the scope of protection of the present invention.

They are used only for the convenience of describing this invention and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0031] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0032] See Figures 1-5The present invention provides an embodiment of a seamless steel pipe cutting device, comprising: a frame 1, a clamping mechanism 2, a mounting base 3, abutment seats 4, a cutting mechanism 5, a control mechanism 6, a deburring mechanism 7, and a driving mechanism 8; the clamping mechanism 2 clamps the seamless steel pipe to restrict its rotation in the circumferential direction and allows it to slide in the axial direction; the mounting base 3 is disposed on the outer side of the seamless steel pipe to be cut; two abutment seats 4 are slidably mounted on the mounting base 3 along the axial direction of the seamless steel pipe; the cutting mechanism 5 is mounted on the mounting base 3 and located between the two sliding seats; the control mechanism 6 pushes the two abutment seats 4 to abut against the outer wall of the seamless steel pipe. The cutting mechanism 5 cuts the seamless steel pipe; the control mechanism 6 applies a force to the two abutment seats 4 to push the two sections of the cut seamless steel pipe away from each other; there are two deburring mechanisms 7 facing each other, both of which are mounted on the mounting base 3, and after the two sections of the cut seamless steel pipe are separated, the two deburring mechanisms 7 abut against the inner and outer sides of both ends of the cut seamless steel pipe to deburr the seamless steel pipe; and the driving mechanism 8 drives the two abutment seats 4 to rotate around the seamless steel pipe to realize the annular cutting of the seamless steel pipe by the cutting mechanism 5 and the annular deburring of the deburring mechanism 7.

[0033] In practice, the clamping mechanism 2 first clamps the seamless steel pipe. Its design, which restricts the circumferential rotation of the seamless steel pipe, ensures the stability of the positioning reference for subsequent cutting and deburring operations, preventing the steel pipe from shifting during operation and affecting processing accuracy. At the same time, the characteristic of allowing the steel pipe to slide along the axial direction provides the necessary conditions for the separation of the two sections of the steel pipe after cutting. Then, the control mechanism 6 pushes the two abutment seats 4 to abut against the outer wall of the seamless steel pipe, achieving precise positioning of the cutting position and ensuring that the cutting mechanism 5, installed on the mounting base 3 and located between the two abutment seats 4, can be aligned with the preset cutting trajectory. Next, the drive mechanism 8 drives the two abutment seats 4 to rotate around the seamless steel pipe, driving the cutting mechanism 5 to complete the circular cut. This linkage rotation design ensures a regular cutting trajectory and uniform cutting depth, improving the cutting quality. After cutting, the control mechanism 6 clamps the two abutment seats 4. The receiving seat 4 applies a force that pushes the two seamless steel pipes after cutting away from each other along the axial direction, effectively avoiding the problem that the two steel pipes sticking together would prevent the subsequent deburring mechanism 7 from operating smoothly, thus ensuring the continuity of the operation. After the two steel pipes are separated, the two deburring mechanisms 7 installed on the mounting seat 3 abut against the inner and outer sides of the cut ends of the two steel pipes respectively. The driving mechanism 8 drives the receiving seat 4 to rotate around the steel pipe again, realizing the annular deburring of the deburring mechanism 7. This rotation linkage design can completely remove burrs on the inner and outer sides of the cut, avoiding manual repair and improving the end processing quality. The whole process forms an integrated operation process of clamping and positioning, precise cutting, end separation, and comprehensive deburring through the coordinated action of each mechanism, which greatly improves the processing efficiency and processing accuracy, while reducing manual intervention and ensuring the stability of processing quality.

[0034] Furthermore, multiple rotating rollers 41 are rotatably mounted on the side of the abutment seat 4 near the seamless steel pipe; the axes of the multiple rotating rollers 41 are arranged parallel to the axis of the seamless steel pipe; during the process of the abutment seat 4 moving toward the seamless steel pipe and completing the positioning, the abutment seat 4 first abuts against the outer wall of the seamless steel pipe through the multiple rotating rollers 41, and the drive mechanism 8 drives the abutment seat 4 to rotate around the seamless steel pipe. At this time, the rotating rollers 41 roll along the outer wall of the seamless steel pipe, and the rolling friction replaces the sliding friction, which greatly reduces the frictional resistance between the abutment seat 4 and the steel pipe, and avoids scratches or damage to the outer wall of the steel pipe due to friction.

[0035] See Figures 1-5 In other embodiments, the drive mechanism 8 includes: an annular component 81, a rotating seat 82, a gear ring 83, a drive gear 84, and a first motor; the annular component 81 is mounted on the frame 1 and is coaxially arranged with the seamless steel pipe; the rotating seat 82 is rotatably mounted on the annular component 81; two abutment seats 4 are mounted on the rotating seat 82 via a control mechanism 6; the gear ring 83 is coaxially fixed on the annular component 81; the drive gear 84 is rotatably mounted on the rotating seat 82 and meshes with the gear ring 83; the first motor drives the drive gear 84 to rotate. In practice, after the first motor starts, it drives the drive gear 84 to rotate. Because the drive gear 84 meshes with the gear ring 83, the rotation of the drive gear 84 is converted into a revolution along the circumference of the gear ring 83, which in turn drives the rotating seat 82 to rotate synchronously around the annular part 81 and the seamless steel pipe. The two abutment seats 4 linked with the rotating seat 82 also rotate around the seamless steel pipe. Finally, the cutting mechanism 5 completes the annular cutting of the seamless steel pipe, and the deburring mechanism 7 completes the annular deburring of the cut of the steel pipe. In this transmission process, the meshing transmission between the gear ring 83 and the drive gear 84 ensures high rotational accuracy and stable torque transmission, so that the rotating seat 82 rotates at a uniform speed. This ensures that the cutting trajectory is regular and the cut is flat, and also achieves comprehensive and uniform deburring. At the same time, the single power source design driven by the first motor simplifies the transmission link and reduces the failure rate of the mechanism. The coaxial layout of the annular part 81 and the seamless steel pipe further avoids the processing error caused by rotational offset and improves the overall processing quality.

[0036] See Figures 1-5In other embodiments, the control mechanism 6 includes: an active telescopic member 61, an elastic telescopic member 62, and a connecting rod 63; the active telescopic member 61 and the elastic telescopic member 62 are arranged along the radial direction of the annular member 81 and are coaxially arranged; one end of the active telescopic member 61 is mounted on the rotating seat 82, and the other end of the telescopic member is fixed to one end of the elastic telescopic member 62; the connecting rod 63 and the abutment seat 4 are arranged in a one-to-one correspondence; the end of the elastic telescopic member 62 away from the rotating seat 82 is hinged to one end of the two connecting rods 63, and the other end of the connecting rod 63 is hinged to the corresponding abutment seat 4. In practical implementation, the active telescopic component 61 can be a structure capable of active linear movement, such as a hydraulic cylinder, pneumatic cylinder, or electric actuator, while the elastic telescopic component 62 can be a structure capable of elastic extension and retraction, such as an elastic telescopic rod. When it is necessary for the abutment seat 4 to abut against the outer wall of the seamless steel pipe, the active telescopic component 61 extends radially along the annular component 81, pushing the coaxially arranged elastic telescopic component 62 to move synchronously and store force. The elastic telescopic component 62 transmits the thrust to the corresponding abutment seat 4 through two hinged connecting rods 63, driving the two abutment seats 4 to move closer to the seamless steel pipe and abut tightly, providing stable positioning for the cutting operation. After the cutting is completed, the active telescopic component 61 remains stationary, and the elastic telescopic component 62, after storing force, releases its elastic force and applies a counterforce to the two abutment seats 4 through the connecting rod 63, pushing the two abutment seats 4 away from each other, thereby causing the two cut seamless steel pipe sections to separate. During this process, the extension action of the active telescopic component 61 achieves precise control of the abutment seats 4, and the stationary state after cutting avoids interference with the release of force by the elastic telescopic component 62. The storage and release of force by the elastic telescopic component 62 not only plays a buffering role to avoid rigid contact damage to the steel pipe or abutment seats 4, but also provides sufficient power for the separation of the abutment seats 4.

[0037] Furthermore, a connecting gear 64 is coaxially fixed at one end of the connecting rod 63 that is hinged to the elastic telescopic member 62, and the two connecting gears 64 mesh with each other; by setting the two connecting gears 64, it can be effectively ensured that the two connecting rods 63 rotate at the same angle.

[0038] See Figures 1-5In other embodiments, the deburring mechanism 7 includes: an extension housing 71, a compression spring 72, a lead screw 73, a nut seat 74, a control gear 75, a control rack 76, an outer blade 77, an inner blade 78, and a power storage assembly 9; a slot 31 is provided on the side of the mounting base 3 near the seamless steel pipe; one end of the extension housing 71 is slidably inserted into the slot 31, and the compression spring 72 applies a spring force toward the seamless steel pipe to the extension housing 71; the lead screw 73 is arranged along the sliding direction of the extension housing 71, and the lead screw 73 is rotatably mounted in the extension housing 71; the nut seat 74 is slidably mounted in the extension housing 71 along the length direction of the lead screw 73, and the nut seat 74 is threadedly connected to the lead screw 73; the power storage gear is rotatably mounted on the nut seat 74, and the axis of the power storage gear is perpendicular to the axis of the lead screw 73; the control rack 75... One end of the control rack 76 is fixed inside the extension housing 71, and the other end of the control rack 76 slides through the nut seat 74. The control rack 76 and the control gear 75 are meshed with each other. The outer blade 77 is fixed outside the power storage housing, and the working surface of the outer blade 77 is inclined. One end of the inner blade 78 is fixed on the control gear 75. The extension housing 71 is provided with a clearance groove 79 for the inner blade 78 to pass through, so that the inner blade 78 rotates through the clearance groove 79 to the outside of the extension housing 71, forming a V-shaped structure with the outer blade 77. When the nut seat 74 moves upward, the control rack 76 and the control gear 75 drive the inner blade 78 to rotate to the outside of the extension housing 71. The sliding of the abutment seat 4 on the mounting seat 3 drives the power storage component 9 to store power, so that after the extension housing 71 slides to the outside of the slot 31, the screw 73 is driven to rotate, which drives the nut seat 74 to move upward.

[0039] In practice, as the abutment seat 4 moves toward the seamless steel pipe, the extension shell 71 first abuts against the seamless steel pipe. The abutment seat 4 continues to move, pushing the extension shell 71 toward the slot 31, causing the compression spring 72 to compress and store energy. After cutting is completed, the abutment seat 4 slides on the mounting seat 3, causing the two sections of seamless steel pipe to separate, and simultaneously driving the energy storage component 9 to store energy. Subsequently, the extension shell 71 separates from the seamless steel pipe, and the compression spring 72 releases its stored energy, pushing the extension shell 71 to slide outside the slot 31 until the outer blade 77 abuts against the outer side of the seamless steel pipe. At this time, the energy storage component 9 releases energy to drive the lead screw 73 to rotate. Because the nut seat 74 is threadedly connected to the lead screw 73, the rotation of the lead screw 73 drives the nut seat 74 to move upward along the length of the lead screw 73. During the movement of the nut seat 74, the control rack 76, which is fixed to the extension shell 71, slides through the nut seat 74 and drives the control gear 75 through meshing with the control gear 75. 5. The control gear 75 rotates, which in turn drives the inner blade 78 fixed thereon to rotate through the clearance groove 79 to the outside of the extension housing 71, forming a V-shaped structure with the outer blade 77, until the inner blade 78 abuts against the inner wall of the seamless steel pipe; then the drive mechanism 8 drives the abutment seat 4 to rotate around the seamless steel pipe, and the inner and outer blades 77 of the V-shaped structure rotate around the steel pipe synchronously, deburring the inner and outer sides of the cut end of the steel pipe; during this process, the threaded transmission of the lead screw 73 and the nut seat 74, and the meshing transmission of the control rack 76 and the control gear 75 ensure that the inner blade 78 rotates smoothly and at a precise angle, until the inner blade 78 fits against the inner wall of the steel pipe, so that the V-shaped structure can adapt to the thickness of the seamless steel pipe; the V-shaped blade structure can fully cover the burrs on the inner and outer sides of the end, and with the rotation action around the pipe, it greatly improves the comprehensiveness and uniformity of deburring. The overall action and transmission coordination effectively ensures the stability and processing quality of the deburring operation.

[0040] See Figures 1-5In other embodiments, the power storage component 9 includes: a square rod 91, a transmission gear 92, a transmission rack 93, and a spiral spring; the square rod 91 is coaxially arranged with the lead screw 73, and one end of the square rod 91 is rotatably mounted on the mounting base 3, while the other end of the square rod 91 is slidably inserted into the lead screw 73; the transmission gear 92 is rotatably mounted on the square rod 91; the transmission rack 93 is arranged along the sliding direction of the abutment seat 4, and the transmission rack 93 is fixedly connected to the abutment seat 4, with the transmission rack 93 meshing with the transmission gear 92; the spiral spring is arranged at the connection between the transmission gear 92 and the square rod 91, with one end of the spiral spring mounted on the square rod 91 and the other end of the spiral spring mounted on the transmission gear 92. In practice, during the sliding process of the abutment seat 4, the transmission rack 93 fixed thereto moves synchronously. The transmission rack 93 drives the transmission gear 92 to rotate through meshing with the transmission gear 92. At this time, because the inner blade 78 has a tendency to rotate, the inner blade 78 will abut against the inner wall of the slot 31. Under the action of the control rack 76 and the control gear 75, the nut seat 74 cannot move, which in turn causes the lead screw 73 to not rotate. The rotation of the transmission gear 92 will cause the spiral spring set at its connection with the square rod 91 to deform and store force. After the extension housing 71 slides to the outside of the slot 31 and the abutment state between the inner blade 78 and the inner wall of the slot 31 is released, the spiral spring releases the stored force and drives the transmission gear 92 to rotate in the opposite direction. Through the sliding insertion and cooperation of the square rod 91 and the lead screw 73, the lead screw 73 rotates synchronously. The rotation of the lead screw 73 drives the nut seat 74 threadedly connected to it to rotate along the lead screw 71. 3. Moving upwards along the length direction, the subsequent linkage control rack 76 and control gear 75 cause the inner blade 78 to rotate until it forms a V-shaped structure with the outer blade 77 and fits against the inner wall of the steel pipe. During this process, the contact between the inner blade 78 and the inner wall of the slot 31 achieves precise triggering and locking of the coil spring's energy storage, preventing premature release of the stored energy. The meshing transmission of the transmission rack 93 and transmission gear 92 ensures the stable conversion of the sliding action of the contact seat 4 into the energy storage action. The energy storage and release of the coil spring provide reliable power for the rotation of the lead screw 73. The sliding connection between the square rod 91 and the lead screw 73 not only ensures power transmission but also adapts to the sliding stroke of the extended housing 71. The coordinated operation of the entire transmission chain makes the energy storage, locking, release, and subsequent rotation and positioning actions of the inner blade 78 smooth and controllable, further improving the accuracy and consistency of the deburring mechanism 7's actions and laying the foundation for stable and efficient deburring operations.

[0041] Furthermore, it also includes a return spring; the return spring applies a sliding return force to the abutment seat 4; after the deburring operation is completed, the return spring releases its stored force and applies a sliding return force to the abutment seat 4, causing the abutment seat 4 to slide back to its original position. At the same time, the abutment seat 4 drives the transmission rack 93 to move in the opposite direction. Through the cooperation of the transmission gear 92 and the spiral spring, the lead screw 73 is driven to rotate in the opposite direction. The reverse rotation of the lead screw 73 causes the nut seat 74 to move down. Then, through the meshing transmission of the control rack 76 and the control gear 75, the inner blade 78 rotates in the opposite direction and retracts into the extension housing 71, completing the entire operation cycle. In this process, the setting of the return spring realizes the automatic reset of the abutment seat 4 and related mechanisms without the need for additional power drive, which improves the automation level and operation continuity of the device and facilitates the next cutting of seamless steel pipes.

[0042] See Figures 1-5 In other embodiments, the cutting mechanism 5 includes a cutting disc 51 and a second motor. The cutting disc 51 is rotatably mounted on the mounting base 3, and the second motor drives the cutting disc 51 to rotate. In specific implementation, the second motor starts and drives the cutting disc 51 to rotate at high speed. At the same time, the driving mechanism 8 drives the abutment seat 4 to rotate around the seamless steel pipe. When the abutment seat 4 drives the mounting base 3 to move to the designated cutting position and completes the positioning of the seamless steel pipe, the high-speed rotating cutting disc 51 moves in a circular motion around the steel pipe synchronously with the mounting base 3, gradually cutting into the wall of the seamless steel pipe until the entire pipe is cut off.

[0043] See Figures 1-5 In another embodiment, the clamping mechanism 2 includes two opposing clamping assemblies; the clamping assembly includes: an annular seat 21 and a plurality of clamping units; the annular seat 21 is mounted on the frame 1; the plurality of clamping units are arranged in a circular array with the circumference of the annular seat 21 as the center; the clamping unit includes: a clamping seat 22 and a clamping roller 23; the clamping seat 22 is slidably mounted on the annular seat 21 along the radial direction, and the sliding distance of the clamping seat 22 is adjustable; the clamping roller 23 is rotatably mounted on one end of the clamping seat 22 near the axis of the annular seat 21, and the axis of the clamping roller 23 is perpendicular to the axis of the annular seat 21. In practice, after the seamless steel pipe is transported to the cutting station, two opposing clamping components synchronously approach the seamless steel pipe. The clamping seat 22 of each clamping unit slides radially towards the steel pipe along the annular seat 21 until multiple clamping rollers 23 are in close contact with the outer wall of the seamless steel pipe. The sliding distance of the clamping seat 22 can be adjusted according to the diameter of the steel pipe so that the clamping rollers 23 can be adapted to steel pipes of different specifications. At the same time, multiple clamping rollers 23 distributed in a circular array uniformly wrap around the steel pipe from the circumference to achieve stable centering clamping. The setting of the clamping rollers 23 can effectively restrict the seamless steel pipe from rotating in the circumferential direction and allow it to slide in the axial direction.
