Abstract
Description
Technical Field
[0001] This application belongs to the field of pipe processing, and in particular relates to a chipless rapid cutting device. Background Technology
[0002] Traditional pipe cutting processes typically employ methods such as flame cutting, abrasive wheel cutting, or saw blade cutting. During operation, workers fix the pipe to a cutting platform, and the pipe is separated by mechanical or thermal action applied through a high-speed rotating cutting tool or a high-temperature flame. In this process, the intense friction or melting between the cutting tool and the metal pipe instantly generates a large amount of high-temperature metal debris and molten slag particles. These particles are flung outwards under centrifugal force and cutting impact, creating widespread and rapid debris pollution. This debris not only pollutes the air in the work area but also reduces visibility, forcing workers to frequently stop to clean equipment and work surfaces. More seriously, the splashing molten metal particles can burn workers' skin or ignite nearby combustibles. Furthermore, long-term inhalation of this fine metal dust can cause respiratory illnesses and even pose a potential risk of metal dust explosions. Therefore, it is necessary to solve these technical problems. Utility Model Content

At this time, the circular cutter, rigidly connected to the cutter seat, feeds radially, cutting into the target pipe wall in a pure extrusion manner instead of the grinding action of a traditional grinding wheel, fundamentally eliminating the generation of metal chips. Simultaneously, the support plate drives the follower sleeve, pressure block, and the entire circular cutting assembly to rotate synchronously, causing the circular cutter to move continuously along the circumference of the pipe under extrusion, forming a circular cutting trajectory. During this process, the rotational extrusion and radial feed of the circular cutter work together to completely cut the pipe under pure plastic deformation without high-temperature friction or material peeling. Therefore, the chip-free rapid cutting device provided in this application can completely solve the problem of flying chip pollution, which is far superior to the prior art.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.
[0037] Please refer to the following: Figures 1 to 4 The present application provides a chip-free rapid cutting device according to an embodiment. This chip-free rapid cutting device includes a support 100, a support plate 200, a follower sleeve 300, a drive mechanism, and a circular cutting assembly. Wherein:
[0038] The support plate 200 is mounted on the support 100 and can rotate around its own central axis; the follower sleeve 300 is coaxially mounted on the support plate 200; the drive mechanism is connected to the support plate 200 and the follower sleeve 300 respectively and is used to drive the support plate 200 and the follower sleeve 300 to rotate synchronously, and also to drive the follower sleeve 300 to move relative to the support plate 200 along the axial direction of the support plate 200; the circular cutting assembly includes a cutter holder 401 and a circular cutter connected to the cutter holder 401. The cutter 402 also includes a pressure block 403 connected to the follower sleeve 300 and a roller 404 rotatably mounted on the cutter holder 401. The cutter holder 401 is slidably connected to the support disk 200 and can move radially along the support disk 200. The axial direction of the circular cutter 402 is parallel to the axial direction of the support disk 200. A slope 405 is formed on the pressure block 403 that is inclined relative to the axial direction of the support disk 200. The roller 404 abuts against the slope 405 and can roll on the slope 405. In this embodiment, the drive mechanism can adopt a structure commonly used in the art, such as a motor 505 drive or a cylinder drive, which will not be described in detail here.
[0039] According to the structure provided in this embodiment, in the chip-free rapid cutting device provided in this embodiment, when the drive mechanism pushes the follower sleeve 300 to move axially along the support plate 200, the pressure block 403 fixed on it can also move forward synchronously. In this way, the inclined slope 405 formed on the pressure block 403 can force the cutter seat 401 to slide radially inward along the support plate 200 by continuously squeezing the roller 404 on the cutter seat 401. At this time, the circular cutter 402, which is rigidly connected to the cutter seat 401, feeds radially and cuts into the target pipe wall in a pure extrusion manner instead of the grinding action of the traditional grinding wheel, fundamentally eliminating the generation of metal chips. At the same time, the support plate 200 drives the follower sleeve 300, the pressure block 403 and the entire circular cutting assembly to rotate synchronously, so that the circular cutter 402 moves continuously along the circumference of the pipe under the extrusion state, forming a circular cutting trajectory. In this process, the rotational extrusion and radial feed of the circular cutter 402 work together to completely cut the pipe under pure plastic deformation without high temperature friction and material peeling. Therefore, the chip-free rapid cutting device provided in this embodiment can completely solve the problem of flying chip pollution, which is far superior to the existing technology.
[0040] In another embodiment of this application, please refer to [the relevant document / reference]. Figures 1 to 4 The circular cutting assembly also includes a cutting shaft 406 connected to the cutting blade holder 401; the circular cutter 402 is coaxially arranged with the cutting shaft 406 and can rotate freely around the cutting shaft 406. According to the structure provided in this embodiment, when the support disk 200 drives the entire circular cutting assembly to revolve around the target pipe, the circular cutter 402 generates tangential friction at the contact point where it compresses the pipe wall. This friction can drive the circular cutter 402 to rotate around the cutting shaft 406. This rotation causes the various parts of the cutting edge of the circular cutter 402 to continuously and alternately contact the cutting area. This not only effectively improves the cutting speed, but also significantly extends the service life of the circular cutter 402 because the wear of the cutting edge is dynamically distributed across the entire circumference rather than concentrated at a single position.
[0041] In another embodiment of this application, please refer to [the relevant document / reference]. Figures 1 to 4The circular cutting assembly also includes a blade holder 407, a pressure blade sleeve 408, and a radial thrust bearing 409. The blade holder 407 is coaxially arranged with the cutting shaft 406, and the pressure blade sleeve 408 is detachably connected to the blade holder 407. The circular cutter 402 is clamped between the pressure blade sleeve 408 and the blade holder 407 in the axial direction of the cutting shaft 406. The radial thrust bearing 409 is coaxially spaced between the blade holder 407 and the cutting shaft 406. According to the structure provided in this embodiment, the pressure blade sleeve 408 can be detachably connected to the blade holder 407 by threads or snaps, which can tightly constrain the circular cutter 402 in the cavity. This not only ensures that the cutter does not move axially during high-speed rotation, but also facilitates quick replacement after wear. The radial thrust bearing 409, located between the blade holder 407 and the cutting shaft 406, allows the circular cutter 402 to rotate more smoothly and freely on the surface of the target pipe, which is beneficial to further improve the cutting speed of the chipless rapid cutting device in this embodiment.
[0042] In another embodiment of this application, please refer to [the relevant document / reference]. Figures 1 to 4 The circular cutting assembly also includes a cutting guide 410 connected to the support disk 200; the cutting guide 410 is arranged radially along the support disk 200, and the cutter holder 401 is slidably connected to the cutting guide 410. According to the structure provided in this embodiment, the cutting guide 410 connected to the support disk 200 can effectively improve the movement stability of the cutter holder 401, which is beneficial to further improve the cutting speed of the chipless rapid cutting device in this embodiment.
[0043] In another embodiment of this application, please refer to [the relevant document / reference]. Figures 1 to 4 The circular cutting assembly also includes a wear-resistant anti-friction layer 411 disposed at the edge of the support disk 200, through which the support disk 200 abuts against the follower sleeve 300. In this embodiment, the anti-friction layer 411 can be made of wear-resistant materials commonly used in the art, such as Teflon or nylon. According to the structure provided in this embodiment, the more wear-resistant anti-friction layer 411 can significantly reduce frictional loss when the support disk 200 and the follower sleeve 300 rotate or move relative to each other; on the other hand, it can ensure that the follower sleeve 300 and the support disk 200 always maintain a tight and stable fit, ensuring more accurate force transmission when the pressure block 403 pushes the roller 404, which is beneficial to further improve the cutting speed of the chipless rapid cutting device in this embodiment.
[0044] In another embodiment of this application, please refer to [the relevant document / reference]. Figures 1 to 4The drive mechanism includes a hollow main shaft 501, a drive sleeve 502, a rotating seat 503, a pulley 504, and a motor 505. The main shaft 501 is mounted on a support 100. The drive sleeve 502 is coaxially fitted on the main shaft 501 and can rotate around the main shaft 501. The rotating seat 503 is keyed to the drive sleeve 502 and can rotate with the drive sleeve 502. It can also move relative to the drive sleeve 502 along the axial direction of the drive sleeve 502. The support plate 200 is coaxially connected to the end of the drive sleeve 502. The follower sleeve 300 is connected to the rotating seat 503. The pulleys 504 are respectively connected to the power shafts of the drive sleeve 502 and the motor 505, and the pulleys 504 are connected to each other by a belt. According to the structure provided in this embodiment, after the motor 505 starts, it can drive the pulley 504 on its power shaft to rotate. The pulley 504 connected to the active sleeve 502 is driven by the belt, so that the active sleeve 502, which is coaxially mounted on the main shaft 501, rotates around the main shaft 501. At this time, the end of the active sleeve 502 directly drives the support disk 200 to rotate synchronously. At the same time, the rotating seat 503, which is keyed to the active sleeve 502, rotates with the active sleeve 502. The rotating seat 503 can slide along the axial direction of the active sleeve 502. The follower sleeve 300, which is fixed to the rotating seat 503, thus simultaneously obtains the same rotational motion as the support disk 200 and the linear movement along the axial direction of the support disk 200. This is beneficial to further improve the cutting speed of the chipless rapid cutting device in this embodiment.
[0045] In another embodiment of this application, please refer to [the relevant document / reference]. Figures 1 to 4 The drive mechanism also includes a radial thrust bearing assembly 506, a pressure cap 507, a first push sleeve 508, a push rod 509, and a first hydraulic cylinder 510. The inner ring of the radial thrust bearing assembly 506 is mounted on the rotating seat 503. The pressure cap 507 is detachably connected to the first push sleeve 508 and is used to cooperate with the first push sleeve 508 to clamp the outer ring of the radial thrust bearing assembly 506. The two ends of the push rod 509 are respectively connected to the power ends of the first push sleeve 508 and the first hydraulic cylinder 510. The output direction of the first hydraulic cylinder 510 and the axial direction of the push rod 509 are both parallel to the axial direction of the main shaft 501. In this embodiment, the radial thrust bearing assembly 506 may include at least two radial thrust bearings 409 commonly used in the art, which will not be described in detail here.
[0046] According to the structure provided in this embodiment, the first hydraulic cylinder 510 can drive the push rod 509 to advance linearly along the main shaft 501 and push the first push sleeve 508 forward. At this time, the pressure cover 507 and the first push sleeve 508 jointly clamp the outer ring of the radial thrust bearing assembly 506, causing it to generate axial displacement. Since the inner ring of the bearing assembly is mounted on the rotating seat 503, the axial thrust of the outer ring is transmitted to the inner ring through the bearing raceway, thereby pushing the rotating seat 503 to slide along the axial direction of the active sleeve 502. Since the inner and outer rings of the radial thrust bearing assembly 506 can rotate independently, the linear advancement of the hydraulic cylinder and the rotational motion of the rotating seat 503 can be completely decoupled, thereby realizing independent and precise control of the rotation and axial movement of the rotating seat 503, which is beneficial to further improve the cutting speed of the chipless rapid cutting device in this embodiment.
[0047] In another embodiment of this application, please refer to [the relevant document / reference]. Figures 1 to 4 The drive mechanism also includes a pressure plate 511 vertically mounted on the main shaft 501, and multiple push rods 509 evenly arranged around the main shaft 501 and all connected to the pressure plate 511. The push rods 509 also pass through the support 100. The drive mechanism also includes a guide sleeve 512 connected to the support 100 and used to guide the movement of the push rods 509. According to the structure provided in this embodiment, since multiple push rods 509 evenly arranged around the main shaft 501 are simultaneously connected to the pressure plate 511, and since the guide sleeve 512 connected to the support 100 can guide the movement of the push rods 509, the axial thrust on the rotating seat 503 can be evenly distributed, ensuring a smooth and reliable movement process, thereby further improving the cutting speed of the chipless rapid cutting device in this embodiment.
[0048] In another embodiment of this application, please refer to [the relevant document / reference]. Figures 1 to 4The chipless rapid cutting device also includes a pipe clamping device for supporting the target pipe; the pipe clamping device includes a base 601, a guide tube 602, a second hydraulic cylinder 603, a second push sleeve 604, a plane bearing 605, a sliding sleeve 606, an end pressure plate 607, and a clamping claw 608; the guide tube 602 is horizontally placed on the base 601 and forms a feeding channel 609 coaxial with the support plate 200, the feeding channel 609 forms a flared mouth 610 at the end away from the support plate 200, the second hydraulic cylinder 603 is connected to the base 601 and its output direction is parallel to the axial direction of the feeding channel 609, the second push sleeve 604 is fitted on the sliding sleeve 606 and its outer circle is connected to the power end of the second hydraulic cylinder 603, and the plane bearing 605 is placed on the second push sleeve 604 and the sliding sleeve 606. Between the sliding sleeves 606, the end pressure plate 607 is detachably connected to the sliding sleeve 606 and cooperates with the sliding sleeve 606 to form an annular groove 611 for clamping the second push sleeve 604 and the plane bearing 605. The sliding sleeve 606 has a T-shaped inclined groove 612 formed on the inner wall near the guide tube 602. The claw 608 is accommodated in the T-shaped inclined groove 612 and can be driven by the sliding sleeve 606 to extend radially into the feed channel 609 along the guide tube 602 during the axial movement of the sliding sleeve 606. Here, it can be understood that the hollow part of the main shaft 501 is coaxially adapted with the feed channel 609. The target tube enters from the feed channel 609, and after extending and passing through the main shaft 501 for a set length, it is clamped by the tube clamping device, and then the circular cutting assembly completes the cutting.
[0049] According to the structure provided in this embodiment, when the pipe clamping device is working, the target pipe can enter the feeding channel 609 from the flared opening 610 of the guide tube 602 away from the support plate 200. After reaching the set length, the second hydraulic cylinder 603 can push the second push sleeve 604 to move axially along the feeding channel 609. Thus, the second push sleeve 604 can also drive the sliding sleeve 606 to move forward synchronously through the plane bearing 605. When the sliding sleeve 606 moves forward, the inclined surface of its T-shaped groove 612 presses against the back of the jaw 608, forcing the jaw 608 housed in the T-shaped groove 612 to retract radially inward along the guide tube 602, thereby stably clamping the target pipe. After cutting is completed, the second hydraulic cylinder 603 retracts, and the sliding sleeve 606 moves backward, which can cause the T-shaped groove 612 to drive the jaw 608 to retract radially, thereby forcibly resetting and opening the jaw 608. This is beneficial to further improve the cutting speed of the chipless rapid cutting device in this embodiment.
[0050] In another embodiment of this application, please refer to [the relevant document / reference]. Figures 1 to 4The chipless rapid cutting device also includes a frame 700, a horizontal slide rail 800 mounted on the frame 700, and a base plate 900 slidably connected to the horizontal slide rail 800; the support 100, the drive mechanism, and the pipe clamping device are all connected to the base plate 900. According to the structure provided in this embodiment, during the cutting process of the current target pipe, since the pipe clamping device clamps the target pipe, the entire chipless rapid cutting device can continue to move along the horizontal slide rail 800 with the target pipe, and the cutting of the target pipe is completed synchronously during the movement. After the cutting action is completed, the base plate 900 can be driven by the linear drive device (not shown) located below the base plate 900, which drives the seat 100, the drive mechanism and the pipe clamping device to reverse and reset along the horizontal slide rail 800 relative to the direction of the target pipe's advance, waiting for the subsequent target pipe to extend into the set length of the pipe clamping device and be clamped and cut again. This cycle repeats. The linear drive device can be a cylinder, linear drive module, rope traction device, etc., as in the prior art. This is beneficial to further improve the cutting efficiency of the chipless rapid cutting device in this embodiment. It is understood that a typical application scenario is that this chipless rapid cutting device is installed in a cold storage room. At the output end of the tube rolling mill, since the cold rolling mill continuously outputs during the cold rolling process, after the target tube of the set length is passed through the feeding channel 609 and the main shaft 100, it is clamped by the tube clamping device, and the circular cutting component begins to cut. The target tube is simultaneously pushed forward along the horizontal slide rail 800 by the tube clamping device. At this time, the target tube and the circular cutting component are relatively stationary axially, allowing for precise cutting. After cutting, the tube clamping device is released, and the linear drive device drives the base plate 900, which in turn drives the seat 100, the drive mechanism, and the tube clamping device to reverse and reset along the horizontal slide rail 800 relative to the direction of the target tube's advance. The next target tube then extends into the feeding channel 609 and the main shaft 100, pushing the tail end of the previous target tube from the main shaft 100. This continues until the next target tube enters the feeding channel 609 to the set length, after which the tube clamping device clamps the current target tube again and begins another cutting action.
[0051] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
