Description

Technical Field

[0001] This utility model relates to the field of pipe processing equipment, and in particular to a pipe cutting machine. Background Technology

[0002] In the important field of metal processing, pipe cutting machines play a crucial role, with wide applications in the process of cutting pipes to length. Currently, industrial demands are trending towards larger diameters and thicker walls. When using traditional pipe cutting machines to process pipes with large length-to-diameter ratios, additional support and clamping mechanisms are often required to effectively support and hold the pipes.

[0003] However, the support and clamping mechanisms currently used are usually arranged separately, making it difficult to ensure that they are at the same level. This has a negative impact on the overall support effect and fails to meet the requirements of industrial production for stable support during pipe cutting. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide at least one beneficial option or create conditions to solve one or more technical problems existing in the prior art.

[0005] The solution to the technical problem of this utility model is: a pipe cutting machine, which includes a frame and a pushing assembly, a chuck assembly, a cutting assembly and a follower support assembly, all of which are arranged on the frame.

The cutting assembly is used to cut the material. The follower support assembly is arranged between the pushing assembly and the chuck assembly. The follower support assembly is used to clamp and support the material.

[0006] The beneficial effects of this utility model are as follows: the frame provides the mounting reference surface for each component, and its internal wiring channels for the electrical control system and hydraulic / pneumatic pipelines are integrated; the cutting component can feed vertically along the radial direction of the pipe, achieving precise and stable cutting operations; the pushing component pushes the pipe along the first slide rail to feed the material to the cutting component, realizing material conveying and improving production efficiency; the chuck component clamps the outer wall of the pipe to prevent axial movement of the pipe due to thrust or vibration during cutting; the follow-up support component forms a three-point stable support at the pushing end, support point, and chuck end during pipe cutting, reducing sagging or swaying caused by the pipe's own weight or cutting vibration, keeping the material in a straight state. By setting up the follow-up support component and placing it between the pushing component and the chuck component for clamping and supporting the material, the previous situation where the separate arrangement of the support mechanism and clamping mechanism made it difficult to ensure horizontality is changed. The follow-up support component can work in conjunction with components such as the pusher and chuck to better ensure that the support for the pipe is in a stable and appropriate horizontal state during the pipe cutting process. It effectively enhances the support effect for the pipe and meets the requirements of industrial production for stable support during pipe cutting.

[0025] In the important field of metal processing, pipe cutting machines play a crucial role, with wide applications in the process of cutting pipes to length. Currently, industrial demands are trending towards larger diameters and thicker walls. When using traditional pipe cutting machines to process pipes with large length-to-diameter ratios, additional support and clamping mechanisms are often required to effectively support and hold the pipes.

[0026] However, the support and clamping mechanisms currently used are usually arranged separately, making it difficult to ensure that they are at the same level. This has a negative impact on the overall support effect and fails to meet the requirements of industrial production for stable support during pipe cutting.

[0027] Therefore, this utility model proposes a pipe cutting machine, referring to... Figures 1-6 It includes a frame 100 and a feeding assembly 500, a chuck assembly 600, a cutting assembly 300, and a follow-up support assembly 700, all mounted on the frame 100. The frame 100 is provided with a first slide rail 110. The feeding assembly 500 is slidably connected to the first slide rail 110, and the chuck assembly 600 is slidably connected to the first slide rail 110. The cutting assembly 300 is used to cut the material. The follow-up support assembly 700 is disposed between the feeding assembly 500 and the chuck assembly 600, and is used to clamp and support the material.

[0028] The frame 100 provides a mounting reference surface for all components and integrates wiring channels for the electrical control system and hydraulic / pneumatic pipelines. The cutting assembly 300 can feed vertically along the radial direction of the pipe, achieving precise and stable cutting operations. The pusher assembly 500 pushes the pipe along the first slide rail 110, feeding it to the cutting assembly 300 to achieve material conveying and improve production efficiency. The chuck assembly 600 clamps the outer wall of the pipe to prevent axial movement of the pipe due to thrust or vibration during cutting. The follower support assembly 700 forms a three-point stable support at the pusher end, support point, and chuck end during pipe cutting, reducing sagging or swaying caused by the pipe's own weight or cutting vibration, keeping the material in a straight line. By setting the follower support assembly 700 and placing it between the pusher assembly 500 and the chuck assembly 600 for clamping and supporting the material, the previous situation where separate arrangement of the support and clamping mechanisms made it difficult to ensure horizontality is changed. The follow-up support component 700 can work in conjunction with components such as pushers and chucks to better ensure that the support for the pipe is in a stable and appropriate horizontal state during the pipe cutting process. It effectively enhances the support effect for the pipe and meets the requirements of industrial production for stable support during pipe cutting. It is especially suitable for pipes with a large length-to-diameter ratio, so that the cutting accuracy will not be affected by swaying due to unstable support.

[0029] During pipe cutting, the pipe to be cut is placed at a suitable position on one side of the pusher assembly 500, accurately positioned in the pushing direction. The pusher assembly 500 is then activated, pushing the pipe along the first slide rail 110 towards the chuck assembly 600. As the pipe is pushed, the follow-up support assembly 700 adjusts its support height and clamping force to provide reliable support and clamping for the pipe. Together with the pusher assembly 500 and the chuck assembly 600, they form a three-point stable support structure, preventing the pipe from sagging or swaying due to its own weight or slight vibrations during the pushing process. This ensures the pipe remains in an ideal straight state, preparing it for subsequent cutting. When one end of the pipe reaches the chuck assembly 600, the chuck assembly 600 clamps the outer wall of the pipe to prevent loosening due to unforeseen circumstances, ensuring the pipe is stably clamped and ready for cutting. Cutting state; the cutting assembly 300 is started, and the cutting blade begins to cut the pipe. During the cutting process, the cutting assembly 300 feeds vertically along the radial direction of the pipe along the gantry frame, ensuring the flatness and perpendicularity of the cut surface. When the pipe reaches the tail section, the chuck assembly 600 releases the pipe, the cutting assembly 300 rises, and the chuck assembly 600 moves along the first slide rail 110 to the side of the cutting assembly 300 away from the pusher assembly 500, so that the cutting assembly 300 is located between the pusher assembly 500 and the chuck assembly 600. The pusher assembly 500 pulls the tail section closer to the cutting assembly 300, the chuck assembly 600 re-clamps the tail section, and the cutting assembly 300 cuts the tail section. This allows materials that would otherwise be unusable due to the obstruction of the chuck assembly 600 to be cut, improving material utilization and achieving tailless cutting.

[0030] During pipe cutting, an unstable pushing speed can lead to deviations in the cutting point position, resulting in uneven cut surfaces that fail to meet the precise dimensions required for fixed-length cutting and reduce the quality of the finished product. Therefore, in one embodiment, the pushing assembly 500 includes a first fixed plate 510, a first bracket 520, a first motor 530, a clamp 540, a first rack 550, and a first gear. The first rack 550 is mounted on the frame 100, the clamp 540 is mounted on one side of the first fixed plate 510, the first bracket 520 is mounted on the other side of the first fixed plate 510, the first bracket 520 has a first slider 521 that cooperates with the first slide rail 110, the first motor 530 is mounted on the first bracket 520, the first gear is coaxially rotatable with the output end of the first motor 530, and the first rack 550 meshes with the first gear. When the feeding operation is started, the first motor 530, mounted on the first support 520, begins to operate. Its output gear meshes with the first rack 550, which is positioned along the length of the frame 100. The motor's rotation drives the first gear to move linearly along the rack 550, converting the motor's rotational motion into linear motion along the first slide rail 110. The clamp 540 applies a pushing force to the pipe placed at the starting position. Under this pushing force, the pipe moves smoothly along the first slide rail 110 towards the chuck assembly 600. During this process, the rack and pinion drive, with its constant transmission ratio, ensures uniform pipe feeding speed and precise feed rate. Regardless of changes in the pipe's length, weight, or other factors, it maintains a stable feeding state, accurately delivering the pipe to the appropriate position for subsequent cutting operations.

[0031] It should be noted that the specific structure and working principle of the fixture 540 are existing technologies and will not be described in detail here.

[0032] When the pusher assembly 500 pushes the tail material, the chuck device 640 blocks the pushing path, preventing the tail material from being cut and resulting in waste of pipe material. Therefore, in one embodiment, the chuck assembly 600 includes a second fixing plate 610, a second bracket 620, a second motor 630, a chuck device 640, a second rack, and a second gear. The chuck device 640 is mounted on one side of the second fixing plate 610, and the second bracket 620 is mounted on the other side of the second fixing plate 610. The second bracket 620 is provided with a second slider 621 that cooperates with the first slide rail 110. The second motor 630 is mounted on the second bracket 620, and the second gear is coaxially rotatable with the output end of the second motor 630. The second rack meshes with the second gear. When the position of the chuck device 640 needs to be adjusted, the second gear at the output end of the second motor 630 meshes with the first rack 550 set along the length of the frame 100. As the second motor 630 rotates, it drives the second gear to make linear motion along the first rack 550. The rotational motion of the second motor 630 is converted into linear motion along the slide rail, so that the chuck device 640 moves along the first slide rail 110 on the frame 100, avoiding the pushing path of the pusher assembly 500. Then the pusher assembly 500 continues to push the tail material, and the chuck device 640 moves to the appropriate position to clamp the tail material. The cutting assembly 300 continues to cut the tail material, so that its position can be flexibly adjusted to meet the requirements of the clamping position of the pipe in different cutting scenarios.

[0033] It should be noted that the specific structure and working principle of the chuck device 640 are existing technologies and will not be described in detail here.

[0034] When faced with pipes with a large length-to-diameter ratio or when subjected to lateral forces during cutting, the pipe's position may shift, leading to a decrease in cutting quality. Therefore, in one embodiment, the first slide rail 110 is disposed on the top surface of the frame 100. A second slide rail 120, parallel to the first slide rail 110, is also disposed on the side of the frame 100 near the chuck assembly 600. The pusher assembly 500 has a first guide slider that cooperates with the second slide rail 120, and the chuck assembly 600 has a second guide slider that cooperates with the second slide rail 120. By disposing of the first slide rail 110 on the top surface of the frame 100 and the second slide rail 120 on the side of the frame 100 near the chuck assembly 600, the pusher assembly 500 and the chuck assembly 600 can obtain support and guidance from different directions. During the feeding and cutting process, the weight of the pipe, the pushing force, and the various forces generated during cutting can be more evenly distributed on the two different slide rails. This avoids the excessive local load on the slide rail caused by the force being concentrated on a single slide rail, thereby reducing problems such as slide rail deformation and wear, improving the stability of the equipment during operation, and ensuring the accuracy of pipe cutting and the movement of each component.

[0035] For pipes of different shapes and sizes, such as large diameter pipes, pipes with large length-to-diameter ratios, or irregular shapes, it may be difficult to reach all the parts that need to be cut, resulting in the inability to complete a comprehensive cutting task. Therefore, in one embodiment, the cutting assembly 300 includes a third slider 330, a third motor 340, a third gear, a linear module 350, a laser cutting head 360, and a third rack 310 and a third slide rail 320, all of which are mounted on the frame 100. The third slider 330 is slidably connected to the third slide rail 320. The third motor 340 drives the third slider 330. The linear module 350 is mounted on the third slider 330, and the laser cutting head 360 is mounted on the linear module 350. The linear module 350 drives the laser cutting head 360 to move. The third gear is coaxially rotatable with the output end of the third motor 340, and the third rack 310 meshes with the third gear. In actual pipe cutting, the two axes work together in coordination. First, the linear module 350 drives the laser cutting head 360 to move vertically to the precise cutting height. Then, the third gear at the output end of the third motor 340 meshes with the third rack 310. As the third motor 340 rotates, it drives the third gear to move linearly along the third rack 310, causing the laser cutting head 360 to move horizontally for cutting. Through this synergistic effect, the laser cutting head 360 has a greater range of motion and flexibility, allowing it to quickly and accurately adjust to the appropriate cutting position and angle according to the shape and size of different pipes and the specific cutting task requirements.

[0036] The pipe cutting process generates a large amount of dust, which permeates the cutting area and fills the entire workspace. Therefore, in one embodiment, the pipe cutting machine further includes a dust removal component 400, which comprises a dust suction hood 410, an exhaust pipe 420, and an exhaust fan. The dust suction hood 410 is mounted on the frame 100 and positioned below the cutting component 300. The exhaust fan is connected to the dust suction hood 410 via the exhaust pipe 420. When the cutting component 300 begins cutting the pipe, the exhaust fan is simultaneously activated. The exhaust fan creates a negative pressure environment within itself. Since the exhaust fan is connected to the dust suction hood 410 below the cutting component 300 via the exhaust pipe 420, the pressure difference causes the air around the cutting area to carry the dust and harmful gases generated during cutting towards the dust suction hood 410, thus ensuring that the cutting area remains relatively clean and effectively preventing the accumulation of dust and harmful gases, creating a favorable environment for the entire cutting process.

[0037] In actual industrial production, it is often necessary to cut pipes of various lengths. Therefore, in one embodiment, multiple follower support components 700 are provided, all of which are positioned between the pusher component 500 and the chuck component 600. By placing multiple follower support components 700 between the pusher component 500 and the chuck component 600, the number and layout of the support components can be flexibly adjusted according to the actual length of the pipe. For longer pipes, multiple follower support components 700 work together to form multiple reliable support points at different locations on the pipe, forming a more stable multi-point support structure together with the pusher end and the chuck end, effectively preventing the pipe from sagging, bending, or swaying due to its own weight or cutting vibration. Since different pipes have significantly different lengths, by selecting multiple or single follower support components 700 to operate according to the pipe length, the pipe cutter can well adapt to the cutting needs of pipes of various lengths.

[0038] In actual production, the specifications and dimensions of pipes vary. In one embodiment, the follower support assembly 700 includes a fourth fixed plate 710, a fourth slider 720, a fourth bracket 730, a clamping device 740, a support device 750, a fourth motor 760, a fourth gear, and a fourth slide rail 711 and a fourth rack 712 disposed on the fourth fixed plate 710. The fourth fixed plate 710 is disposed on the frame 100, the fourth motor 760 is disposed on the fourth slider 720, the fourth gear is coaxially rotatably disposed with the output end of the fourth motor 760, the fourth rack 712 meshes with the fourth gear, the fourth motor 760 drives the fourth slider 720 to reciprocate along the fourth slide rail 711, the support device 750 is disposed on the top surface of the fourth slider 720, the fourth bracket 730 is disposed on the side of the fourth slider 720 away from the fourth fixed plate 710, and the clamping device 740 is disposed on the fourth bracket 730. When the pipe enters the cutting area under the push of the pusher assembly 500, the fourth gear at the output end of the fourth motor 760 meshes with the fourth rack 712 on the fourth fixed plate 710. As the fourth motor 760 rotates, the fourth gear moves linearly along the fourth rack 712, driving the fourth slider 720 to reciprocate along the fourth slide rail 711. In this way, the support device 750 mounted on the fourth slider 720 and the clamping device 740 connected to the fourth slider 720 via the fourth bracket 730 also move together, achieving vertical position adjustment and enabling them to quickly and accurately reach the position where the pipe needs support and clamping. The support device 750 rises to a suitable height, providing stable support to the pipe from below, while the clamping device 740 rises simultaneously to a suitable position, clamping and fixing the pipe from the side, ensuring that the pipe maintains a stable position and posture during the cutting process.

[0039] During the cutting process, the pipe experiences force changes due to uneven weight distribution and cutting vibrations. These forces are directly transmitted to the entire support device 750 and the connected equipment structure, leading to increased overall equipment vibration. Therefore, in one embodiment, the support device 750 includes a roller 751 and two buffer devices 752. The buffer devices 752 are disposed between the roller 751 and the fourth fixed plate 710. The buffer devices 752 are used to buffer the up-and-down movement of the roller 751. Each buffer device 752 includes a locking screw 7521 and a spring 7522. The locking screw 7521 and the spring 7522 correspond one-to-one. The roller 751 is fixed to the fourth fixed plate 710 by the locking screw 7521. The spring 7522 is sleeved on the locking screw 7521. One end of the spring 7522 is connected to the roller 751, and the other end of the spring 7522 is connected to the fourth fixed plate 710. When the fourth motor 760 drives the support device 750 to rise, the roller 751 contacts the surface of the pipe, and the pipe exerts a reverse force on the roller 751. This force is transmitted to the buffer device 752 through the roller 751. At this time, the spring 7522 begins to be compressed, and the stop screw 7521 acts as a guide and limiter, ensuring that the spring 7522 can only be compressed and deformed along the axial direction of the stop screw 7521. During compression, spring 7522 stores elastic potential energy, absorbing and converting the impact force generated when roller 751 contacts the pipe into elastic potential energy, thus playing a buffering and shock-absorbing role and avoiding hard collisions between roller 751 and the pipe. As roller 751 continuously supports the pipe, due to factors such as uneven weight distribution of the pipe and cutting vibration, roller 751 will be subjected to constantly changing forces. When the force increases, spring 7522 will be further compressed to increase the buffering force to adapt to the greater impact force. When the force decreases, spring 7522 will gradually recover part of its deformation, release elastic potential energy, maintain the supporting force on roller 751, and ensure that roller 751 always maintains good contact with the pipe, while continuously buffering and absorbing vibrations to maintain the stability of the support.

[0040] When faced with external forces such as cutting vibration, the clamping block 744 may loosen due to insufficient clamping force or structural instability, causing the pipe to lose effective fixation and affecting the normal progress of the cutting operation. Therefore, in one embodiment, the clamping device 740 includes a mounting plate 741, a fifth motor 742, a crossbar 743, a fifth slide rail 7411, a sixth slide rail 7412 perpendicular to the fifth slide rail 7411, two clamping blocks 744, and two connecting rods 745. The mounting plate 741 is mounted on the fourth bracket 730. The fifth slide rail 7411 and the sixth slide rail 7412 are mounted on the mounting plate 741. The crossbar 743 is slidably connected to the fifth slide rail 7411. All the clamping blocks 744 are slidably connected to the sixth slide rail 7412. One end of each connecting rod 745 is hinged to a clamping block 744, and the other end of each connecting rod 745 is hinged to the center of the crossbar 743. The fifth motor 742 is mounted on the mounting plate 741, and the output end of the fifth motor 742 is fixedly connected to the crossbar 743. When the pipe needs to be clamped, the piston of the fifth motor 742 pushes the crossbar 743, which is fixedly connected to it, to move linearly along the fifth slide rail 7411 on the mounting plate 741. Since one end of the connecting rod 745 is hinged to the clamping block 744 and the other end is hinged to the center of the crossbar 743, when the crossbar 743 moves under the drive of the fifth motor 742, the connecting rod 745 will rotate and drive the clamping block 744 to slide along the sixth slide rail 7412, which is perpendicular to the fifth slide rail 7411. When the crossbar 743 is pulled downwards, the connecting rod 745 will drive the two clamping blocks 744 to move closer to each other along the sixth slide rail 7412, gradually clamping the pipe; when the crossbar 743 is pushed upwards, the connecting rod 745 will drive the two clamping blocks 744 to move further apart along the sixth slide rail 7412, thereby releasing the pipe, realizing fast and stable pipe clamping and releasing actions; when dealing with pipes of different specifications, only the stroke of the fifth motor 742 needs to be controlled to make the clamping blocks 744 adjust the clamping distance according to the actual diameter of the pipe, so as to effectively clamp pipes of different diameters.
