Description

Technical Field

[0001] The invention relates to the technical field of pipe cutting machines, in particular to a rotary cutting pipe cutting machine. Background Art

[0002] Pipe cutting is one of the important processes in pipeline processing. Its purpose is to cut the pipe body into the required length or shape by cutting to meet the requirements of subsequent processing or use. Pipe cutting is usually applicable to pipe bodies of various materials, such as metal pipes, plastic pipes, composite pipes, etc., which are widely used in construction, machinery manufacturing, petrochemical and other fields. The efficiency and quality of pipe cutting directly affect the processing accuracy and production cost of the product. Therefore, the optimization and improvement of pipe cutting technology has always been the focus of research in related fields.

[0003] At present, pipe cutting machines on the market usually use two cutting methods: one is to fix the tube body and rotate the cutter, which is suitable for cutting small-diameter tubes, such as metal tubes or plastic tubes with a diameter between 10mm and 50mm. This method gradually completes the cutting by rotating the cutter to ensure that the cutting path is accurate and uniform, but because the cutter needs to pass through the tube completely, the cutting efficiency is limited, and it is not suitable for tubes with larger diameters. The other is a circular cutting method with the tube body rotating and the cutter fixed. This method is more suitable for thin-walled tubes, such as aluminum alloy tubes or stainless steel tubes with a wall thickness of 1mm to 3mm. By rotating the tube body, the cutter can achieve uniform circular cutting, but when the tube body diameter is large or the material is thicker, the stability and processing accuracy of the rotating tube body will be affected to a certain extent.

[0004] How to organically integrate the method of fixing the tube body and rotating the cutter with the method of circular cutting with rotating tube body and fixed cutter, so as to achieve both precise cutting of small-diameter tubes and efficient circular cutting of thin-walled tubes, has become a key issue in current tube cutting technology research.

DETAILED DESCRIPTION

[0036] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] In addition, the term "and / or" in this article is only a description of the association relationship between the associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0038] like Figures 1 to 12 As shown, the rotary tube cutting machine comprises: a machine body 1, a tube rotating mechanism 3 and a tube cutting mechanism 2. The tube rotating mechanism 3 and the tube cutting mechanism 2 are both mounted on the machine body 1 to form an integral structure.

[0039] The pipe rotating mechanism 3 includes a fixing plate 31, a first driving assembly 32 and a clamping assembly 33. The fixing plate 31 is arranged on the machine body 1 to provide mounting support for the clamping assembly 33; the clamping assembly 33 is connected to the fixing plate 31 by rotation to clamp the pipe body 4. The first driving assembly 32 is also installed on the machine body 1 and connected to the clamping assembly 33 to drive the clamping assembly 33 to rotate the pipe body 4. The clamping assembly 33 can achieve stable clamping of pipes of different diameters or materials through adjustment, thereby meeting various pipe cutting requirements.

[0040] The tube cutting mechanism 2 includes a rotatable cutter 23 , and the cutter 23 is used to cut the tube body 4 .

[0041] When in use, the operator first places the pipe body 4 at the clamping position on the machine body 1, and clamps the pipe body 4 through the clamping assembly 33 to prevent the pipe body from deflecting or loosening during rotation. Then, the first drive assembly 32 is started, so that the clamping assembly 33 drives the pipe body 4 to rotate at a preset speed. Then, the second drive assembly is started to control the cutter assembly to move along the guide rail and gradually contact the rotating pipe body 4 to cut it. Since the pipe body 4 continues to rotate during the cutting process, the cutting efficiency is significantly improved, while ensuring the flatness and accuracy of the cutting surface.

[0042] The rotary cutting tube cutting machine of the present invention realizes efficient cutting of small-caliber and thin-walled tubes through the cooperation of tube rotation and fixed cutting knife, and at the same time has both versatility and ease of operation, and is particularly suitable for tube cutting scenarios requiring high-precision processing.

[0043] In this embodiment, the machine body 1 is provided with a guide channel steel 12, and the guide channel steel 12 is provided with a first support assembly 11 along its length direction, and the first support assembly 11 can slide along the guide channel steel 12 to support and guide the movement of the tube body 4. During operation, the tube body 4 is placed on the first support assembly 11, and the first support assembly 11 is moved along the guide channel steel 12 by the driving device, thereby driving the tube body 4 to move along a predetermined direction.

[0044] like Figure 3 and Figure 4As shown, the structure of the first support assembly 11 is designed as follows: it includes a base 111, two rollers 112, a bending plate 113, an arc seat 114, a first adjustment screw 115 and two first support wheels 116. The base 111 is slidably arranged on the guide channel steel 12, and its bottom is in contact with the guide channel steel 12 through a guide rail or a roller to achieve stable sliding movement. The two rollers 112 are rotatably connected to the base 111 and contact the upper surface of the guide channel steel 12. The rotation of the rollers 112 ensures that the first support assembly 11 can move smoothly along the guide channel steel 12. The bending plate 113 is slidably connected to the base 111, and its position can be adjusted by an adjustment device. The arc seat 114 is fixedly connected to the bending plate 113, and is used to install and support the first support wheel 116. The first adjustment screw 115 is threadedly connected to the base 111, and one end is rotatably connected to the bending plate 113. When the first adjusting screw 115 is rotated, the bending plate 113 can be driven to slide along the inclined surface of the base 111, thereby adjusting the position of the arc seat 114. The two first support wheels 116 are rotatably connected to the arc seat 114, used to support the tube body 4 and form a limited space for the tube body 4. While supporting the tube body 4, the first support wheel 116 allows the tube body 4 to rotate freely around its own axis. In actual use, the tube body 4 is first placed in the limited space between the two first support wheels 116. By driving the first support assembly 11 to move along the guide channel steel 12, the two rollers 112 rotate accordingly, thereby driving the entire support assembly to move smoothly. In order to adapt to tubes 4 of different diameters, the position of the bending plate 113 can be adjusted by rotating the first adjusting screw 115, so that the height of the arc seat 114 and the first support wheel 116 changes accordingly. Since the upper surface of the base 111 is inclined, when the bending plate 113 moves in the horizontal direction, the arc seat 114 will rise and fall accordingly, thereby accurately adjusting the supporting height of the tube body 4 .

[0045] The above design ensures that the pipe body 4 can remain stable during the support process, and at the same time realizes its free rotation around the axis, meeting the operational requirements of rotary cutting. Through the highly adjustable support structure, the device can adapt to pipes of different diameters and materials, improving the versatility and processing accuracy of the pipe cutting equipment.

[0046] like Figure 5 and Figure 6 As shown, in this embodiment, a second support assembly 13 is further provided on the machine body 1 for stably supporting and adjusting the height of the end of the tube body 4 to meet the cutting requirements of tubes with different diameters.

[0047] The structure of the second support assembly 13 includes: a mounting plate 131 , a first cylinder 132 , two connecting plates 133 , a second support wheel 134 , two first supporting arms 135 , two second supporting arms 136 , a first connecting shaft 137 , a second connecting shaft 138 and a second adjusting screw 139 .

[0048] The structure of the second support assembly 13 includes: a mounting plate 131, a first cylinder 132, two connecting plates 133, a second supporting wheel 134, two first arms 135, two second arms 136, a first connecting shaft 137, a second connecting shaft 138 and a second adjusting screw 139. The mounting plate 131 is fixedly mounted on the machine body 1, and is provided with two mounting parts 1311, each of which is provided with a first slide groove 1312. The second adjusting screw 139 passes through the mounting plate 131 and is threadedly connected thereto, and the height adjustment of the assembly is achieved by rotating the second adjusting screw 139. One end of the two first arms 135 is hingedly mounted between the two mounting parts 1311, and the other end thereof is slidably connected to the second slide groove 1331 through the first connecting shaft 137. The two second arms 136 are arranged crosswise with the first arms 135, and the intersection is hingedly connected. One end of the second arm 136 is connected to the connecting plate 133 through the second connecting shaft 138, and the other end is inserted into the first slide groove 1312 through the third connecting shaft 1351. The two connecting plates 133 are slidably connected to the first connecting shaft 137 through the second slide groove 1331, and are fixed to each other through the second connecting shaft 138. A second support wheel 134 is also installed on the connecting plate 133, and the second support wheel 134 is used to support the end of the tube body 4, while allowing the tube body to rotate freely in its axial direction to meet the working requirements of peeling. The first cylinder 132 is fixedly mounted on the mounting plate 131, and its output end passes through the mounting plate 131 and is connected to a positioning block 1321. By controlling the extension and contraction of the first cylinder 132, the positioning block 1321 can rise or fall to limit the end of the tube body 4 to ensure the stability of the tube body during the cutting process.

[0049] In actual use, by controlling the output end of the first cylinder 132 to extend, the positioning block 1321 rises accordingly, effectively limiting the end of the tube body 4 to prevent the tube body from axial displacement during the cutting process. For tube bodies 4 of different diameters, the support height is adjusted by rotating the second adjusting screw 139. When the second adjusting screw 139 is rotated, the screw drives the connecting plate 133 to rise or fall along the vertical direction of the mounting plate 131. The movement of the connecting plate 133 simultaneously drives the synchronous movement of the first connecting shaft 137 and the second connecting shaft 138. During the movement of the connecting plate 133, the intersection angle of the first support arm 135 and the second support arm 136 changes accordingly. The first connecting shaft 137 slides in the second slide groove 1331, and the third connecting shaft 1351 slides in the first slide groove 1312. The change in the intersection angle further drives the second support wheel 134 to rise or fall accordingly. Through the above adjustment, the second support wheel 134 can be accurately adjusted to an appropriate height according to the diameter of the tube body 4, thereby providing stable support. At the same time, the rotation connection design of the second supporting wheel 134 allows the tube body 4 to rotate freely around its axis during the cutting process to meet the requirements of the rotary cutting operation.

[0050] like Figure 7 , Figure 8 , Fig. 9 , Fig.10 and Fig.11 As shown, in this embodiment, the structure of the clamping assembly 33 is designed as follows, including two rotating disks 331, two guide plates 332 and three clamping blocks 333. Through the clamping assembly 33, the tube body 4 can be firmly clamped, and the first driving assembly 32 can be used to rotate the tube body 4.

[0051] The two rotating disks 331 are rotatably mounted on both sides of the fixed plate 31, and each rotating disk 331 is provided with a circular hole for the tube body 4 to pass through. The diameter of the circular hole is designed to be slightly larger than the outer diameter of the tube body 4, so that the tube body 4 can smoothly pass through the rotating disk 331. The two guide plates 332 are respectively arranged on both sides of the two rotating disks 331, and the two guide plates 332 are fixedly connected by three fourth connecting shafts 3321 to form an integral structure. Each fourth connecting shaft 3321 is provided with a first rolling bearing 3322, and the first rolling bearing 3322 contacts the inner wall of the circular hole of the rotating disk 331 to ensure that the rotating disk 331 can rotate freely relative to the guide plate 332. The three clamping blocks 333 are equidistantly arranged between the two rotating disks 331, and one end of each clamping block 333 is connected to the rotating disk 331 by a rotating connection. The rotating disk 331 is provided with an arc groove 3311, and the other end of the clamping block 333 passes through the arc groove 3311 and is slidably connected to the arc groove 3311 through a pin shaft 3331. In addition, a guide groove 3323 is provided on the guide plate 332, and the pin shaft 3331 also passes through the guide groove 3323 and is slidably connected to the guide groove 3323. The rotating disk 331 is connected to the first driving assembly 32, and the first driving assembly 32 drives the rotation of the rotating disk 331 to drive the corresponding movement of the clamping block 333 and the tube body 4.

[0052] Pass the tube body 4 through the circular hole on the rotating disk 331 so that it is placed in the middle of the three clamping blocks 333. At this time, the tube body 4 is preliminarily aligned with the clamping assembly 33. Start the first drive assembly 32 to drive the rotating disk 331 to rotate at a set speed. The rotation of the rotating disk 331 drives the three clamping blocks 333 to rotate. Since the pin shaft 3331 of the clamping block 333 is slidably connected with the guide groove 3323, and the pin shaft 3331 also slides in the arc groove 3311 of the rotating disk 331, the clamping block 333 will produce a swinging motion. During the swinging process, the three clamping blocks 333 gradually approach and clamp the tube body 4 to complete the clamping action. After the clamping block 333 clamps the tube body 4, the first drive assembly 32 continues to drive the rotating disk 331 to rotate. At this time, the clamping block 333 will drive the tube body 4 to rotate together through its clamping contact with the tube body 4. Since the guide plate 332 is in a stationary state or rotates at a speed lower than that of the rotating disk 331, the pin 3331 of the clamping block 333 continues to slide in the guide groove 3323, pushing the guide plate 332 to move relative to the rotating disk 331. As the rotating disk 331 continues to rotate, the guide plate 332 is finally driven by the swing of the clamping block 333 and rotates at a speed synchronized with the rotating disk 331. The entire clamping assembly 33 achieves a stable clamping and rotation drive of the pipe body 4 through the power input of the first drive assembly 32, ensuring stability and accuracy during the cutting process. The clamping block 333 swings under the drive of the rotating disk 331, thereby automatically adapting to pipe bodies 4 of different diameters and achieving efficient and reliable clamping.

[0053] In this embodiment, the two rotating disks 331 are fixedly connected by a plurality of fifth connecting shafts 3312 to form an integral structure. The fifth connecting shafts 3312 are distributed in an annular equidistant array, and each fifth connecting shaft 3312 is sleeved with a second rolling bearing 3313. The second rolling bearing 3313 contacts the inner wall of the circular hole of the fixed plate 31 to ensure that the rotating disk 331 can rotate smoothly relative to the fixed plate 31. The fifth connecting shaft 3312 is designed in an annular equidistant array and is evenly distributed between the two rotating disks 331 to ensure that the rotating disk 331 is evenly stressed during the rotation process. The second rolling bearing 3313 is sleeved on the fifth connecting shaft 3312 and forms a relative rotation connection structure between the rotating disk 331 and the fixed plate 31 by contacting the inner wall of the circular hole of the fixed plate 31. This design reduces the rotation resistance and improves the rotation stability. Through the rolling contact between the second rolling bearing 3313 and the inner wall of the circular hole of the fixed plate 31, the rotating disk 331 can rotate freely relative to the fixed plate 31 while maintaining the overall rigidity of the structure.

[0054] The first drive assembly 32 includes a first motor 321 and a driving wheel 322. The output end of the first motor 321 is connected to the driving wheel 322, and a plurality of shifting teeth 3221 are evenly arranged on the driving wheel 322 for engaging with the second rolling bearing 3313. When the first motor 321 is started, its output end drives the driving wheel 322 to rotate. The shifting teeth 3221 on the driving wheel 322 shift the second rolling bearing 3313 engaged therewith one by one. As the second rolling bearing 3313 is shifted, the fifth connecting shaft 3312 rotates accordingly, thereby driving the two rotating disks 331 to rotate synchronously. Through the engagement drive of the shifting teeth 3221 and the second rolling bearing 3313, the rotational power is transmitted from the first motor 321 to the fifth connecting shaft 3312, and then the fifth connecting shaft 3312 drives the two rotating disks 331 to rotate. This driving method utilizes a simple and efficient mechanical transmission structure, avoids a complex transmission mechanism, and improves the reliability and maintainability of the equipment.

[0055] like Figure 7 and Figure 8 As shown, in this embodiment, the coil mechanism 3 further includes a brake assembly 34, which includes a second cylinder 341 and a gate 342. The gate 342 is rotatably connected to the fixed plate 31. The output end of the second cylinder 341 is connected to the gate 342 to drive the gate 342 to swing. A brake ring 3324 is provided on the guide plate 332, and the brake ring 3324 is located between the two gates 342. The second cylinder 341 is started, and the output end of the second cylinder 341 is controlled to extend. The output end of the second cylinder 341 will drive the two gates 342 to approach each other until the gate 342 contacts the brake ring 3324, and the brake ring 3324 is braked or fixed by means of the friction between the gate 342 and the brake ring 3324.

[0056] like Figure 1 and Fig.12 As shown, in this embodiment, the structure of the pipe cutting mechanism 2 is designed as follows, including a mounting frame 21, two knife seats 22, a cutter 23, two third cylinders 24 and a second drive assembly 25. Through the cooperation of these components, accurate cutting of the pipe body 4 is achieved. The mounting frame 21 is fixedly mounted on the machine body 1, and is used to support and connect other components of the pipe cutting mechanism 2. The two knife seats 22 are rotatably connected to the mounting frame 21, respectively, and the knife seats 22 can rotate relative to the mounting frame 21 under the restriction of the mounting frame 21, providing mobile support for the cutter 23. The cutter 23 is rotatably mounted on the knife seat 22, and the driving assembly provides rotational power for cutting the pipe body 4. The output ends of the two third cylinders 24 are rotatably connected to the knife seats 22, respectively, and the other ends thereof are rotatably connected to the machine body 1. By controlling the extension and contraction of the third cylinder 24, the knife seat 22 can be driven to rotate relative to the mounting frame 21, thereby adjusting the position of the cutter 23.

[0057] The second driving assembly 25 is used to drive the cutter 23 to rotate, and its specific structure includes a third motor 251, a driving pulley 252, two driven pulleys 253, a transmission belt 254, a tensioning wheel assembly 255, two first guide wheels 256 and two second guide wheels 257.

[0058] The third motor 251 is fixedly mounted on the machine body 1, and its output end is connected to the driving pulley 252. The driving pulley 252 is connected to two driven pulleys 253 through a transmission belt 254, and the two driven pulleys 253 are respectively connected to the two cutters 23. The transmission belt 254 passes around the driving pulley 252 and the driven pulley 253 to form a transmission chain. The transmission belt 254 also passes around the tensioning wheel of the tensioning wheel assembly 255 and contacts the first guide wheel 256 and the second guide wheel 257. The tensioning wheel assembly 255 is used to adjust the tension of the transmission belt 254 to ensure transmission efficiency and stability; the first guide wheel 256 and the second guide wheel 257 provide guide support for the transmission belt 254 to ensure the accuracy of the transmission path. When the third motor 251 is started, its output end drives the driving pulley 252 to rotate, and the driving pulley 252 drives the driven pulley 253 to rotate through the transmission belt 254, and the driven pulley 253 further drives the cutter 23 to rotate, thereby realizing the high-speed cutting function of the cutter 23. During the cutting process, by controlling the output ends of the two third cylinders 24 to extend or retract, the knife holder 22 is driven to rotate relative to the mounting frame 21, and the two cutters 23 gradually approach the pipe body 4 as the knife holder 22 moves. The approach and rotation of the cutter 23 are combined to complete the cutting of the pipe body 4.

[0059] Through the multi-wheel transmission system of the second drive assembly 25, the cutter 23 can achieve stable high-speed rotation, thereby improving cutting efficiency and accuracy. The third cylinder 24 drives the rotation of the cutter seat 22, so that the cutter 23 can flexibly adjust its position to meet the cutting requirements of pipes 4 of different diameters and materials. The coordination of the tensioning wheel assembly 255 and the guide wheel system ensures that the transmission belt 254 maintains appropriate tension and guidance during operation, prevents transmission slippage or deviation, and improves the operating stability of the equipment. The power is transmitted to the cutter 23 through the transmission belt 254, which reduces the complex mechanical transmission mechanism, optimizes the spatial layout of the pipe cutting mechanism 2, and facilitates maintenance and adjustment.

It should be understood by those skilled in the art that various modifications, combinations, sub-combinations and substitutions can be made according to design requirements and other factors. Any modification, equivalent substitution and improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
