Description

Technical Field

[0001] This application relates to the field of cutting technology, and in particular to a metal pipe shearing machine. Background Technology

[0002] In fields such as engineering machinery, automobile manufacturing, building decoration, and home appliance production, fixed-length shearing of metal pipes is a core process in pipe processing. Its processing accuracy and efficiency directly affect the quality and production rhythm of subsequent assembly, welding, and other processes. With the upgrading of manufacturing towards automation and large-scale production, and the increasing demand for high-precision components, more stringent requirements are being placed on the consistency of length shearing and continuous processing capabilities of metal pipes.

[0003] Traditional metal pipe shearing machines typically require manual placement of long pipes at the shearing station, manual adjustment of positioning, and shearing with a single blade. After shearing, the cut section must be manually removed, the long pipe repositioned, and its position recalibrated, repeating the shearing operation. However, manual positioning is labor-intensive, cumbersome, and prone to significant positioning errors after multiple operations. Furthermore, continuous processing is not possible during shearing, resulting in low efficiency. Summary of the Invention

[0015] Compared with the prior art, the beneficial effects of this application are as follows: (1) The present invention proposes a metal pipe shearing machine tool, which is provided with an installation ring 1, several insertion rods 1, several rotating rollers, several clamping plates, several buffer springs, a limiting ring, several protrusions 1, a baffle, an installation frame 1, an installation ring 2, a deflecting plate 1, a limiting plate, a support frame 1, a hydraulic rod, a cutter, a support plate 1, a support plate 2, the aforementioned toothed plate 1, and a gear 1. The installation ring 2 is driven to rotate by a drive assembly, which synchronously drives the deflecting plate 1 to deflect the baffle, so that the limiting ring drives the protrusions 1 to rotate, thereby pushing the rotation. The roller, insert rod 1, and clamping plate approach and stably clamp the pipe body. At the same time, the drive assembly drives gear 1 to mesh with toothed plate 1 through the linkage assembly. In conjunction with sliding assembly 1 and sliding assembly 2, support plate 1 and support plate 2 push the pipe body. Then, the hydraulic rod drives the cutter to complete the shearing. After shearing, the drive assembly continues to run to realize the cycle of clamping assembly releasing and pipe body pushing, clamping, and shearing again. This realizes the automatic clamping and fixing of metal pipes while positioning and pushing them. The processing is continuous and efficient, with low manual labor intensity and convenient operation.

[0016] (2) The present invention proposes a metal pipe shearing machine tool, which is equipped with a sliding groove plate, a collection box, a second mounting frame, a third support plate, a mounting plate, a second protrusion, and a second actuating plate. After the shearing assembly cuts the pipe body, the resulting pipe segments will fall onto the sliding groove plate. With the help of the inclined setting of the sliding groove plate, the segments will slide down naturally under the action of gravity and fall into the collection box. The collection box adopts a plug-in design, which is convenient to remove, empty and reuse. At the same time, the rotating rod drives the mounting plate and the second protrusion with a continuous and smooth gradient in radial height to rotate. The second protrusion is in continuous contact with the second actuating plate, and applies different thrusts to the second actuating plate according to the change of its own radial height. This pushes the sliding groove plate to cyclically adjust the tilt angle around the torsion spring shaft at the top of the third support plate, so that the falling position of the segments is evenly distributed in the collection box. No manual adjustment is required to avoid stacking and congestion in a single position, and smooth and efficient uniform collection is achieved. Attached Figure Description

[0026] The present application will be further described below with reference to specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0027] In the description of this application, it should be noted that the terms "center", "lateral", "longitudinal", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc., which indicate the orientation and positional relationship based on the orientation or positional relationship shown in the accompanying drawings, are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and should not be construed as limiting the specific protection scope of this application.

[0028] It should be noted that the terms "first," "second," etc., in the specification and claims of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0029] One preferred embodiment of this application, such as Figures 1 to 8As shown, a metal pipe shearing machine includes: a worktable 1, and further includes: a pipe body 10, a support assembly, a clamping assembly, a drive assembly, a linkage assembly, a shearing assembly, and a collection assembly; the pipe body 10 is horizontally positioned directly above the top of the worktable 1; the support assembly is installed on one side of the top of the worktable 1 to support one side of the pipe body 10; the clamping assembly is installed on the other side of the top of the worktable 1 to clamp the other side of the pipe body 10; the drive assembly is installed on the other side of the top of the worktable 1 to drive the clamping assembly to perform the clamping operation on the other side of the pipe body 10; the linkage assembly is installed between the drive assembly and the support assembly to drive the support assembly through the linkage assembly to push the pipe body 10 horizontally; the shearing assembly is positioned directly above the other side of the top of the worktable 1 to shear the pipe body 10; and the collection assembly is positioned on the other side of the top of the worktable 1 to collect multiple parts cut off from the pipe body 10.

[0030] First, one side of the pipe body 10 is placed on the support assembly, and the other side passes through the clamping assembly. Then, the drive assembly is activated, which drives the clamping assembly to firmly clamp the other side of the pipe body 10. At this time, the shearing assembly cuts the corresponding part of the pipe body 10 from top to bottom. The cut parts are collected by the collection assembly on the other side of the top of the worktable 1. After the shearing is completed, the drive assembly is activated again. The drive assembly first drives the clamping assembly to release the clamping assembly on the pipe body 10. At the same time, the drive assembly drives the support assembly to move horizontally on the worktable 1 through the linkage assembly, thereby pushing the pipe body 10 forward to a preset distance. When the drive assembly drives the clamping assembly from the fully open state to gradually approach and begin to contact the pipe body 10, and then slowly clamps it to the fully clamped state, the linkage assembly stops driving the support assembly to move, and the pipe body 10 is positioned. Then, the shearing assembly is activated again to perform the next shearing. This cycle is repeated to realize the continuous automatic shearing of metal pipes. It realizes the automatic clamping and fixing of metal pipes while positioning and pushing them, making the processing continuous and efficient, with low manual labor intensity and convenient operation.

[0031] Further reference Figures 1-7The clamping assembly includes: a mounting ring 201, several insert rods 202, several rotating rollers 203, several clamping plates 204, several buffer springs 205, a limiting ring 206, several protrusions 207, a baffle 208, a mounting bracket 209, a mounting ring 2010, a toggle plate 2011, and a limiting plate 2012. The mounting ring 201 is fitted onto the other side of the pipe fitting body 10. Several insertion slots are equidistantly opened on the outer circumference of the mounting ring 201. Several insert rods 202 are respectively inserted into several insertion slots. Several rotating rollers 203 are respectively rotatably mounted on one end of several insert rods 202. The clamping plates 204 are arc-shaped and are respectively fixedly installed. At the other end of several insertion rods 202, several buffer springs 205 are respectively fixedly installed between one end of several insertion rods 202 and the outer circumference of the mounting ring 201. A limiting ring 206 is sleeved around several rotating rollers 203. Several protrusions 207 are respectively arranged at equal intervals and fixedly installed on the inner circumference of the limiting ring 206. The two sides of the protrusions 207 are symmetrically inclined, and the middle position of the protrusions 207 is set in an open concave arc shape. The middle position of the protrusions 207 is concentric with the mounting ring 201. Several baffles 208 are respectively fixedly installed on one side of the outer circumference of the limiting ring 206. The inner circumference of the mounting bracket 209 is rotatably mounted to the other side of the outer circumference of the limiting ring 206 via bearings. The mounting ring 2010 is fitted over the limiting ring 206. Several actuating plates 2011 are hinged to one side of the inner circumference of the mounting ring 2010 via torsion spring shafts. The other side of the inner circumference of the mounting ring 2010 is rotatably mounted to the outer circumference of the mounting frame 209 via a shaft. Several limiting plates 2012 are equidistantly arranged and fixedly installed on the inner circumference of the mounting ring 2010. The limiting plates 2012 are located at one end of the actuating plates 2011. The shearing assembly includes: a support frame 901, a hydraulic rod 902, and a cutter 903. The support frame 901 is positioned directly above the mounting frame 209. The hydraulic rod 902 is vertically fixedly installed at the bottom of the support frame 901. 03 Vertically fixedly installed at the bottom of hydraulic rod 902, the support assembly includes: support plate one 904 and support plate two 905. The bottom of support plate one 904 is slidably installed on the top of worktable 1 through sliding assembly one. Support plate two 905 is arc-shaped and horizontally fixedly installed on the top of one side of support plate one 904. A toothed plate one 906 is slidably installed on the top of worktable 1 through sliding assembly two. One side of one end of toothed plate one 906 is fixedly installed with the bottom of one end of support plate one 904. A gear one 907 is rotatably installed on one end of the top of worktable 1. Several tooth blocks on gear one 907 are divided into several gear tooth groups. The several gear tooth groups are arranged at intervals. Gear one 907 meshes with toothed plate one 906.

[0032] First, the other side of the pipe body 10 is passed through the mounting ring 201, and one side of the pipe body 10 is placed on the support plate 905 for support. Then, the drive assembly is started, which drives the mounting ring 2010 to rotate. The actuating plate 2011, which is hinged to the inner wall of the mounting ring 2010, rotates synchronously with it. Under the limiting action of the limiting plate 2012, the actuating plate 2011 contacts the baffle 208 on the outer circumference of the limiting ring 206 and actuates the baffle 208, thereby driving the limiting ring 206 to rotate around the mounting bracket 209. When the limiting ring 206 rotates, the protrusions 207, which are equidistantly arranged on its inner wall, rotate synchronously. In the initial state, the protrusions 207 are in contact with the rotating roller 203 with one inclined surface. As they rotate, they gradually pass through... A thrust is applied to the inclined plane, pushing the rotating roller 203 to move the insertion rod 202 closer to the pipe body 10 along the insertion port of the mounting ring 201. Simultaneously, the buffer spring 205 at one end of the insertion rod 202 is compressed until the concave arc-shaped part in the middle of the protrusion 207 rolls into contact with the rotating roller 203. At this point, the arc-shaped clamping plate 204 at the other end of the insertion rod 202 is tightly fitted to the outer circumference of the pipe body 10. Because the middle part of the protrusion 207 is concentric with the mounting ring 201, the distance between the rotating roller 203 and the mounting ring 201 remains constant. The clamping plate 204 provides stable clamping to the pipe body 10. The clamping plate 204 is made of elastic material, which can buffer compression during clamping. Then, the hydraulic rod 902 at the bottom of the support frame 901 is activated. 02 extends vertically downwards, causing the cutter 903 at its bottom to move downwards synchronously, cutting the pipe body 10 protruding from the corresponding position of the mounting ring 201. After cutting, the drive assembly continues to run, causing the mounting ring 2010, the limit ring 206, and the protrusion 207 to rotate continuously. At this time, the rotating roller 203 contacts the other inclined surface of the protrusion 207. As the rotating roller 203 rolls along the other inclined surface, the buffer spring 205 gradually returns to its original position, causing the insertion rod 202 and the clamping plate 204 to move away from the pipe body 10 until the clamping plate 204 is completely separated from the circumferential outer wall of the pipe body 10. During this process, the gear 907 initially engages with the toothed plate 906 with its toothless part, without moving the toothed plate 906. When the clamping plate 201... 4. After completely disengaging from the pipe body 10, the gear teeth on gear 907 begin to mesh with gear plate 906, causing gear plate 906 to slide on the top of worktable 1 via sliding assembly 2. This, in turn, causes support plate 904, which is fixedly connected to gear plate 906, to move horizontally synchronously via sliding assembly 1. Support plate 905 on top of support plate 904 then pushes the pipe body 10 outward. As the drive assembly continues to drive, the next protrusion 207 rotates to contact the rotating roller 203, and again pushes the rotating roller 203, insertion rod 202, and clamping plate 204 closer to the pipe body 10 via a side inclined surface. When clamping plate 204 is about to contact the outer circumference of the pipe body 10, the toothless part of gear 907 engages with gear plate 906 again.The engagement of the toothed plate 906 is stopped, and the support plates 904 and 905 cease pushing the pipe body 10. Then, the concave arc-shaped portion in the middle of the protrusion 207 rolls into contact with the rotating roller 203, and the clamping plate 204 again forms a stable clamp on the pipe body 10. At this time, the hydraulic rod 902 again drives the cutter 903 to move downwards for shearing. This cycle repeats, achieving continuous automatic shearing of the metal pipe. No frequent manual operation is required throughout the process, significantly improving processing continuity and efficiency. After all the pipe bodies 10 have been cut, the drive assembly only needs to be started in reverse. The drive assembly drives the mounting ring 2010 to rotate in the opposite direction. The actuating plate 2011 on the inner wall of the pipe fitting 10 rotates synchronously in the opposite direction. At this time, without the obstruction of the stop plate 2012, the actuating plate 2011 rotates flexibly around the torsion spring shaft, without effectively contacting the baffle 208 on the limit ring 206. Therefore, it cannot drive the limit ring 206 and the protrusion 207 to rotate. The buffer spring 205 remains in the reset state. The insertion rod 202 drives the clamping plate 204 to continuously move away from the circumferential outer wall of the pipe fitting body 10. The clamping assembly remains in the released and reset state throughout the process, facilitating the replacement of a new pipe fitting body 10. This achieves automatic clamping and fixing while positioning and pushing the metal pipe fitting, resulting in continuous and efficient processing, low manual labor intensity, and convenient operation.

[0033] Further reference Figures 1-7 The drive assembly includes: gear 2 301, gear 3 302, a rotary motor 303, and a rotating rod 304. Gear 2 301 is fitted onto the outer circumferential wall of mounting ring 2 2010. Gear 3 302 is vertically mounted on the other side of one end of the top of the worktable 1. Gear 3 302 meshes with gear 2 301. Rotary motor 303 is fixedly mounted on one side of one end of the top of the worktable 1. One side of rotating rod 304 is horizontally fixedly mounted on the output shaft of rotary motor 303. The other side of rotating rod 304 passes through the side of gear 3 302 away from rotary motor 303. The linkage assembly includes: bevel gear 1 305 and bevel gear 2 306. Bevel gear 1 305 is fixedly mounted on the other side of rotating rod 304. Bevel gear 2 306 is fixedly mounted on the top of gear 1 907 via a connecting rod. Bevel gear 1 305 meshes with bevel gear 2 306.

[0034] When the rotating motor 303 is started, its output shaft synchronously drives the horizontally mounted rotating rod 304 to rotate. The rotating rod 304 passes through the gear 302 and drives the gear 302 to rotate synchronously. Since the gear 302 meshes with the gear 2 301 sleeved on the outer circumference of the mounting ring 2010, the rotation of the gear 302 drives the gear 2 301 to rotate through tooth transmission, thereby driving the mounting ring 2010 to rotate synchronously, providing power for the clamping or releasing action of the clamping assembly. At the same time, the bevel gear 305 fixedly mounted on the other side of the rotating rod 304 rotates together with the rotating rod 304. Since the bevel gear 305 meshes with the bevel gear 306 fixed to the top of the gear 907 through a connecting rod, the rotation of the bevel gear 305 drives the bevel gear 306 to rotate, thereby driving the gear 907 to rotate on the top of the worktable 1 through the connecting rod, providing power for the support assembly to push the pipe body 10 to move horizontally, realizing the synchronous linkage transmission between the drive assembly and the linkage assembly.

[0035] Further reference Figures 1-3 and Figure 6 The collection components include: a sliding groove plate 401, a collection box 402, and a second mounting bracket 403. The sliding groove plate 401 is located on the side of the first mounting bracket 209 away from the first support plate 904. The end of the sliding groove plate 401 away from the rotating motor 303 is inclined downward. A slot is provided on the other side of the top of the other end of the worktable 1. The second mounting bracket 403 is fixedly installed between the bottom inner walls on both sides of the slot. The collection box 402 is located in the slot.

[0036] After the shearing assembly cuts the pipe body 10, the resulting pipe segments will fall directly onto the sliding groove plate 401. Since the end of the sliding groove plate 401 away from the rotating motor 303 is inclined downwards, the pipe segments will slide naturally down the inclined surface of the sliding groove plate 401 under the action of gravity, and finally fall precisely into the collection box 402 in the top slot at the other end of the worktable 1. The collection box 402 is a plug-in type and is placed on the mounting bracket 403 fixed between the inner walls of the bottom of the slot through the slot. When the collection box 402 is full of pipe segments, the collection box 402 can be directly removed from the mounting bracket 403 for emptying. After emptying, the collection box 402 can be reinserted into the mounting bracket 403 in the slot to continue the collection operation of pipe segments.

[0037] Further reference Figure 1 , Figure 3 , Figure 4 as well as Figure 6A support plate 3 501 is vertically fixed on the other side of the top of the workbench 1. The top of the support plate 3 501 is rotatably mounted to the bottom outer wall of the sliding groove plate 401 via a torsion spring shaft. A mounting plate 502 is sleeved on one side of the rotating rod 304. A protrusion 2 503 is fixedly mounted on the outside of the mounting plate 502. The radial height of the protrusion 2 503 is set to gradually increase in a continuous and smooth manner along the circumference of the mounting plate 502. The protrusion 2 503 forms a closed, gradually changing circumferential profile. A toggle plate 2 504 is fixedly mounted on the bottom outer wall of the sliding groove plate 401 near the end of the rotating motor 303. The toggle plate 2 504 contacts the protrusion 2 503.

[0038] When the drive assembly is running, the rotating rod 304 synchronously drives the mounting plate 502 fitted on one side to rotate. The second protrusion 503 fixed to the outside of the mounting plate 502 moves in a circular motion along with the mounting plate 502. The radial height of the second protrusion 503 increases continuously and smoothly in a gradual manner along the circumference of the mounting plate 502, forming a closed gradual circumferential profile. Since the bottom outer wall of the sliding groove plate 401 is fixed with the second actuating plate 504 near the rotating motor 303, and the second actuating plate 504 keeps in contact with the second protrusion 503, during the rotation of the second protrusion 503, it will apply different degrees of thrust to the second actuating plate 504 as its own radial height changes. When the radial height of the second protrusion 503 is small, the thrust on the second actuating plate 504 is small. Under the elastic action of the torsion spring shaft, the sliding groove plate 401 maintains a small tilt angle. At this time, the cut pipe segments slide down the groove plate and fall into the collection box 402 at the end away from the support plate 501. As the second protrusion 503 continues to rotate, its radial height gradually increases, and the thrust on the second actuating plate 504 increases synchronously. This pushes the sliding groove plate 401 to rotate around the torsion spring shaft at the top of the third support plate 501, and the tilt angle gradually increases. Consequently, the falling point of the pipe segment shifts towards the end of the collection box 402 closer to the third support plate 501. When the second protrusion 503 rotates to its maximum radial height, its radial height gradually decreases as it continues to rotate, and the thrust on the second actuating plate 504 weakens. The torsion spring shaft drives the sliding groove plate 401 to rotate in the opposite direction and reset, and the tilt angle returns to its initial state. The falling point returns to the end of the collection box 402 away from the third support plate 501. In this way, as the rotating rod 304 continues to rotate, the tilt angle of the sliding groove plate 401 changes cyclically, and the falling position of the pipe segment is evenly distributed in the collection box 402. This achieves even distribution and collection of the segments without manual adjustment, avoiding congestion caused by stacking in a single location.

[0039] Further reference Figures 1-4 and Figure 8 An installation opening is provided on the top of one side of the support plate 904. An electric telescopic rod 601 is horizontally fixed to the inner wall of the installation opening via a bracket. A push plate 602 is vertically fixed to one side of the electric telescopic rod 601. An elastic pad 603 is fixed to one side of the push plate 602.

[0040] When the pipe body 10 is cut to its last section, and the last remaining section cannot fall into the sliding groove plate 401 by the conventional push of the support assembly, the electric telescopic rod 601 is activated. The electric telescopic rod 601 extends and retracts horizontally through the bracket, driving the push plate 602, which is vertically fixed on one side, to move towards the pipe body 10. The elastic pad 603 on one side of the push plate 602 first contacts the last section of the pipe body 10. Under the buffer protection of the elastic pad 603, damage to the outer wall of the pipe is avoided during the push. Then the electric telescopic rod 601 continues to extend, and the push plate 602 and the elastic pad 603 jointly apply the pushing force to smoothly push the last section of the pipe body 10 onto the sliding groove plate 401. Under the action of gravity, the pipe slides down the inclined surface of the sliding groove plate 401 and finally falls into the collection box 402 to complete the collection.

[0041] Further reference Figure 1 and Figure 3 Mounting bracket 1 209 is provided with mounting housing 1 701. The top outer wall of mounting housing 1 701 is fixedly installed with the bottom of support bracket 1 901. Gear 1 907 is provided with mounting housing 2 702.

[0042] The mounting housing 701 is installed outside the mounting frame 209, and its top outer wall is fixedly connected to the bottom of the support frame 901. At the same time, the inner circumferential or side inner walls of the mounting housing 701 are fixed to the mounting ring 201 through connecting plates, shafts and other connecting parts, so that the mounting ring 201 remains stable during operation, avoiding positional displacement caused by shearing vibration or pushing action, and improving the overall operational stability of the structure. The mounting housing 702 is installed outside the gear 907, forming a closed protection for the gear 907. The two together can prevent external dust, debris and other impurities from entering the gaps of the clamping components, gear transmission and other core components, avoiding impurities from affecting the rotational flexibility and fitting accuracy of the components, and preventing external collisions from damaging the internal components, effectively protecting all moving parts and transmission structures, and extending the overall service life of the equipment.

[0043] Further reference Figure 2 The first sliding component includes a slide rail 801 and a slider 802. The slide rail 801 is fixedly installed on one side of the top of the worktable 1, and the slider 802 is slidably installed on the slide rail 801. The slider 802 is fixedly installed on the bottom of the support plate 904. The second sliding component includes a slide rail 803 and two sliders 804. The slide rail 803 is fixedly installed on one end of the top of the worktable 1, and the sliders 804 are slidably installed on the slide rail 803. The two sliders 804 are fixedly installed on both sides of the bottom of the toothed plate 906.

[0044] Support plate 904 slides stably on slide rail 801 via slider 802, ensuring smooth horizontal movement when support plate 904 drives support plate 905 to push the pipe body 10. Tooth plate 906 slides stably on slide rail 803 fixed at one end of the top of worktable 1 via two sliders 804 fixed on both sides of the bottom, ensuring precise and smooth movement when tooth plate 906 drives support plate 904, avoiding deviation and jamming.

[0045] Further reference Figure 5 The top edge of the baffle 208 away from the toggle plate 2011 is a smooth curved surface, and the bottom edge of the toggle plate 2011 away from the baffle 208 is a curved surface.

[0046] When the drive assembly rotates the mounting ring 2010, the actuating plate 2011 on the inner wall of the mounting ring 2010 rotates with it and contacts the baffle 208 on the limiting ring 206. Since the top edge of the baffle 208 away from the actuating plate 2011 and the bottom edge of the actuating plate 2011 away from the baffle 208 are both smooth curved surfaces, they can smoothly slide against each other when in contact, and the actuating plate 2011 can smoothly complete the actuating action of the baffle 208, thereby driving the limiting ring 206 to rotate and realize the clamping of the clamping assembly. When rotating in the opposite direction, the two separate more smoothly. The advantage of this design is that it can greatly reduce the frictional resistance when in contact, avoid jamming and sticking, ensure the smoothness of the transmission linkage, reduce wear at the edges, extend the service life of the baffle 208 and the actuating plate 2011, and avoid stress concentration caused by sharp edge contact, protect the structural integrity of the components, and ensure stable and reliable clamping action.

[0047] Further reference Figure 6 The edge of the top of the second toggle plate 504 away from the collection box 402 is curved, the cross section of the collection box 402 is trapezoidal, and the top of the end of the collection box 402 near the support plate 3 501 is inclined towards the support plate 3 501.

[0048] When the rotating rod 304 drives the mounting plate 502 and the second protrusion 503 to rotate, the second protrusion 503 smoothly contacts and slides against the curved edge of the top of the second actuating plate 504 away from the collection box 402. This smoothly pushes the second actuating plate 504 to adjust the tilt angle of the sliding groove plate 401. The cut pipe segments slide down the sliding groove plate 401 and finally fall into the collection box 402, which has a trapezoidal cross-section. The top of the end of the collection box 402 closest to the third support plate 501 tilts towards the third support plate 501. To further guide the cut segments smoothly into the box, the curved edge of the second actuating plate 504 can reduce the frictional resistance with the second protrusion 503, avoiding jamming during contact and ensuring the stability of the angle adjustment of the sliding groove plate 401. The trapezoidal cross-section and inclined top of the collection box 402 enlarge the feed opening, preventing the pipe segments from accumulating or getting stuck at the box opening, making collection smoother and more efficient. At the same time, the trapezoidal structure can also help the segments to distribute naturally in the box, and together with the angle change of the sliding groove plate 401, uniform collection can be achieved, improving the collection effect.

[0049] Working principle: First, place one side of the pipe body 10 on the support plate 905 of the support assembly, and pass the other side through the mounting ring 201. Then, start the rotating motor 303. The output shaft of the rotating motor 303 drives the rotating rod 304 to rotate. The rotating rod 304 drives the gear 302 to rotate. The gear 302 meshes and drives the gear 301 and the mounting ring 2010 to rotate. The actuating plate 2011 on the inner wall of the mounting ring 2010 rotates synchronously with it. Under the limiting action of the limiting plate 2012, the actuating plate 2011 contacts the baffle 208 on the limiting ring 206 and actuates the baffle 208, causing the limiting ring 206 to rotate around the mounting bracket 209. The protrusion 207 on the inner wall of the limiting ring 206 rotates synchronously. One side of the protrusion 207... The inclined plane contacts the rotating roller 203 and applies a thrust, pushing the rotating roller 203 to drive the insertion rod 202 to move closer to the pipe body 10 along the insertion port of the mounting ring 201. The buffer spring 205 is compressed until the concave arc-shaped part in the middle of the protrusion 207 rolls into contact with the rotating roller 203. The clamping plate 204 at the other end of the insertion rod 202 fits tightly against the outer circumference of the pipe body 10 to form a stable clamp. Then, the hydraulic rod 902 of the shearing assembly is activated. The hydraulic rod 902 extends and retracts vertically downward, driving the cutter 903 to move downward and shear the pipe body 10 protruding from the corresponding position of the mounting ring 201. After shearing, the drive assembly continues to run, and the mounting ring 2010, the limit ring 206, and the protrusion 207 continue to rotate. 03 contacts the other inclined surface of protrusion 207, and buffer spring 205 gradually returns to its original position, driving insertion rod 202 and clamping plate 204 to move away from the pipe body 10 until clamping plate 204 completely disengages from the outer circumference of pipe body 10. During this process, gear 907 initially engages with toothed plate 906 with its toothless portion. After clamping plate 204 completely disengages, rotating rod 304 drives bevel gear 305 to rotate. Bevel gear 305 meshes and drives bevel gear 306 and gear 907 to rotate. The gear teeth on gear 907 mesh with toothed plate 906. Toothed plate 906 slides on slide rail 803 via slider 804 of sliding assembly 2, driving support plate 904 via slider 802 of sliding assembly 1. The slide rail 801 moves horizontally synchronously, and the support plate 905 pushes the pipe body 10 outward. As the drive assembly continues to drive, the next protrusion 207 rotates to contact the rotating roller 203, pushing the clamping plate 204 closer to the pipe body 10. When the clamping plate 204 is about to contact the pipe body 10, the toothless part of the gear 907 engages with the toothed plate 906 again, stopping the push. The middle part of the protrusion 207 contacts the rotating roller 203, and the clamping plate 204 clamps stably again. The hydraulic rod 902 drives the cutter 903 to cut again. This cycle repeats to achieve continuous automatic cutting. After all the pipe bodies 10 have been cut, the rotating motor 303 is started in reverse, and the mounting ring 2010 rotates in reverse.The actuating plate 2011 is blocked by the limit plate 2012 and rotates around the torsion spring shaft, without effectively contacting the baffle 208. The limit ring 206 and the protrusion 207 do not rotate, the buffer spring 205 remains in the reset position, the clamping plate 204 continues to move away from the pipe body 10, and the clamping assembly is in the released reset state for easy replacement of new pipe fittings. The pipe cuttings generated by shearing fall onto the sliding groove plate 401. With the help of the inclined setting of the sliding groove plate 401, they slide down into the collection box 402 under the action of gravity. When the collection box 402 is full, it can be removed from the mounting bracket 403 for emptying. When reinserted and used, and the drive assembly is running, the rotating rod 304 drives the mounting plate 502 and the second protrusion 503 to rotate. The second protrusion 503 contacts the second actuating plate 504 and applies different thrusts to the second actuating plate 504 according to its own radial height change. This pushes the sliding groove plate 401 to cyclically adjust its tilt angle around the torsion spring shaft at the top of the support plate 3 501, so that the pipe segments are evenly distributed in the collection box 402, avoiding stacking and congestion. When the pipe body 10 is cut to the last segment, the electric telescopic rod 601 is activated. The electric telescopic rod 601 extends and retracts horizontally to push the pipe segment. Plate 602 and elastic pad 603 move towards the last section of pipe body 10, smoothly pushing it onto sliding groove plate 401, and finally falling into collection box 402. Housing 1 701 and Housing 2 702 block external dust and debris, prevent external collisions, protect moving parts and transmission structures, and extend the overall service life of the equipment. Support plate 1 904 slides stably on slide rail 1 801 via slider 1 802, and toothed plate 1 906 slides stably on slide rail 2 803 via slider 2 804, ensuring precise, smooth, and uninterrupted movement. When the actuating plate 2011 contacts the smooth curved edge of the baffle 208, it slides smoothly and closely, reducing frictional resistance, preventing jamming, reducing wear, protecting the structural integrity of the components, and ensuring stable and reliable clamping action. The protrusion 503 smoothly contacts the curved edge of the actuating plate 504, ensuring stable angle adjustment of the sliding groove plate 401. The trapezoidal cross-section and inclined top guide the cutting segment of the collection box 402 to smoothly enter, preventing accumulation and jamming at the box opening, achieving uniform and efficient collection. The entire process requires no frequent manual operation, resulting in continuous and efficient processing, low labor intensity, and convenient operation.
