Description

Technical Field

[0001] This invention relates to the field of pipe bending cutting technology, and in particular to a mechanical cutting device for pipe bending production. Background Technology

[0002] In the field of pipe processing, pipe bends are key components widely used in industries such as construction, chemical engineering, and machinery manufacturing. As industries increasingly demand higher precision and production efficiency in pipe forming, the integration of pipe bending and machining processes has become a core requirement.

[0003] Currently, the mainstream mechanical cutting devices for pipe bending production on the market have two major problems.

[0004] Firstly, the cutting accuracy is generally low: the cutting components of existing equipment mostly adopt fixed trajectories or manual adjustment structures, lacking real-time monitoring and dynamic correction mechanisms for cutting position and cutting depth. They are prone to deviations in cutting dimensions due to factors such as pipe deformation and equipment vibration, especially for irregularly shaped bends, resulting in a high scrap rate.

[0005] Secondly, the pipe bending and cutting operations are set up separately: most equipment requires the pipe to be bent by an independent pipe bending machine first, and then the bent pipe is transferred to a special cutting equipment for processing. This not only increases the time and labor costs of the intermediate transfer links, but may also further affect the accuracy of the final product due to collisions and positioning deviations during the transfer process. At the same time, the separate layout also results in a large footprint of the equipment, which is not suitable for the space requirements of small and medium-sized production scenarios.

[0006] Furthermore, the existing cutting equipment lacks sufficient safety protection and automation. Some devices lack emergency escape structures, making them prone to safety accidents when cutting components malfunction; and the adjustment of cutting parameters relies on manual experience, making it difficult to adapt to the bending needs of pipes of different specifications and materials, thus hindering the improvement of production efficiency and product consistency. Summary of the Invention

[0007] This invention provides a mechanical cutting device for pipe bending production.

[0008] A mechanical cutting device for pipe bending production includes: a pipe bending machine housing; vertical plates symmetrically arranged at the top front and back of the pipe bending machine housing; sheet metal cover plates on the top of the vertical plates on both sides; a main machine housing II fixedly mounted at the top center of the sheet metal cover plates; two sets of rollers I arranged at the top of the pipe bending machine housing; a motor I arranged inside the pipe bending machine housing at the bottom of the two sets of rollers I; a fixing component I arranged at the front of the pipe bending machine housing; a fixing seat arranged at the top of the fixing component I; a motor II fixedly mounted on the fixing seat; a pipe bending protrusion fixedly mounted on the shaft of the motor II; a roller II mounted on the pipe bending protrusion; a fixing seat II arranged at the upper right side of the pipe bending machine housing; a limit component fixedly mounted on the fixing seat II; a base plate I arranged at the bottom right side of the pipe bending machine housing; support plates arranged on the left and right sides of the base plate II; and support plates arranged on the left and right sides of the base plate II. The top and bottom of the side support plate are respectively equipped with connecting beam 1 and connecting beam 2. The middle of the support plate is fixed with a cutting chassis by bolts. The left support plate is fixed with a motor 3 by bolts. A lead screw is fixed in the center of the horizontal axis of the cutting chassis. A bearing 1 is fixed on the outside of the left support plate of the lead screw. A roller 1 is fixed on the bearing 1. The roller 1 is connected to the roller 2 on the shaft of the motor 3 by a belt. A cutting base is movably sleeved on the lead screw. A cutting component is set on the cutting base. A guide rail 1 is set on the top of the front and rear sides of the cutting chassis. A guide rail groove is set on the bottom of the front and rear sides of the cutting base. The guide rail groove mates with the guide rail 1. A main unit box 1 is fixed on the rear side of the cutting base by bolts. A linear motor is set in the center of the top of the main unit box 1.

[0009] Main unit 2 is electrically connected to motors 1, 2, and 3. Main unit 2 is used to control the operation of motors 1, 2, and 3. Two sets of rollers 1 are used to transport the unbent tube product to the bending protrusion by rotating rollers 1. The bending protrusion is used to bend the unbent tube product by contacting it with rollers 2. Motor 2 is used to control the position of the bending protrusion, thereby controlling the bending arc. The limiting component is used to limit the product after bending and support the completion of the next cutting operation. Motor 3 is used to drive roller 1 to rotate via belt, which in turn drives the lead screw to rotate. The rotation of the lead screw drives the cutting base to move left and right on the lead screw, and the cutting base in turn drives the cutting component to move.

[0010] Preferably, the cutting assembly includes: a base, a transmission pulley fixedly mounted on the base, a servo motor mounted on the left side shaft of the transmission pulley, a cutting disc mounted on the right side of the transmission pulley, a buffer rod and a safety assembly mounted at the bottom of the transmission pulley, the safety assembly including: a cylinder and a fixing rod, and multiple sets of guide rail recesses mounted at the bottom of the base. The safety assembly is used to rotate the transmission pulley through the front shaft under the action of the cylinder and the fixing rod, thereby transferring the cutting disc and avoiding danger.

[0011] Guide rails are fixedly installed on the left and right sides of the top of the cutting base. The top of the telescopic rod of the linear motor is fixedly connected to the center of the bottom of the base. Guide rails cooperate with guide rail recesses. The linear motor is used to drive the cutting base to move along the direction of guide rails, thereby moving the cutting disc. The cutting disc is used to cut the product after the pipe bending process.

[0012] Preferably, a triangular metal plate is fixedly installed on the side of the base, and a slide rod is fixedly installed on the side of the cutting base. A displacement sensor is movably installed on the slide rod. The displacement sensor is fixedly connected to the triangular metal plate. The displacement sensor is used to follow the movement of the base and sends the displacement data to the main unit.

[0013] Preferably, a slide rod 2 is fixedly installed on the bottom front side of the cutting base, and a displacement sensor 2 is movably installed on the slide rod 2. The displacement sensor 2 is fixedly connected to the bottom of the front side plate of the cutting base. The displacement sensor 2 is used to send displacement data to the main unit box 1 when the cutting base moves left and right.

[0014] The main unit is used to control the real-time movement of the cutting base and the base.

[0015] Preferably, the limiting component includes: a base plate two, with support columns on both the front and rear sides of the top center of the base plate two, bolt columns fixedly installed at the four corners of the top of the base plate two, U-shaped connectors fitted on the bolt columns on the left and right sides of one side, rotating shaft plates symmetrically arranged on the top of the U-shaped connectors, rotating shafts fixedly installed on the rotating shaft plates, rollers first fitted on the rotating shafts, and rollers second movably installed on the support columns on the front and rear sides. Rollers first and second are used to limit the product after the tube bending process, and also provide support for subsequent cutting processes.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] In the cutting assembly, displacement sensor one is fixedly connected to the triangular metal plate, which can monitor the up and down movement of the cutting assembly base along guide rail two in real time and transmit the data to the main unit one; displacement sensor two captures the left and right movement trajectory of the cutting base along the lead screw in real time. The dual displacement data provides the main unit one with a precise control basis, ensuring that the cutting head can dynamically correct the position deviation and avoid cutting dimension errors caused by pipe deformation and equipment vibration. It is especially suitable for high-precision irregular pipe bending processing.

[0018] The cutting assembly is equipped with a buffer rod and a safety component. The buffer rod can mitigate the impact force during the cutting process and reduce equipment wear. The safety component, through the cooperation of a cylinder and a fixed rod, can drive the transmission pulley to rotate around the front shaft in the event of equipment failure or emergency, quickly transferring the cutting disc and preventing the cutting disc from colliding with the pipe or equipment parts. This improves operational safety from a structural perspective and makes up for the shortcomings of existing devices in terms of safety protection.

[0019] The servo motor of the cutting assembly provides stable power to the transmission pulley, ensuring uniform rotation speed of the cutting disc. Combined with the dual drive structure of the linear motor driving the cutting assembly to move along the second guide rail and the lead screw driving the cutting base to move left and right, the cutting trajectory is automatically controlled. At the same time, the displacement sensor feeds real-time data back to the main unit, which can automatically adjust the cutting position and depth according to preset parameters. This eliminates the need for repeated manual calibration, reduces reliance on operator experience, and improves production efficiency and product consistency.

[0020] Through dynamic monitoring by displacement sensor 1 and displacement sensor 2 and real-time control by main unit 1, the cutting assembly can flexibly adjust the up-down and left-right positions of the cutting disc. Combined with the adjustment of the position of the bending protrusion by motor 2, the device can adapt to the bending requirements of pipes of different diameters and materials, and can also achieve precise cutting for pipes of different curvatures. This solves the problems of poor adaptability of existing devices and the need for frequent mold replacement or equipment adjustment.

[0021] The device integrates the pipe bending mechanism and the cutting mechanism into the same pipe bending machine box. After the pipe is bent, it can be directly positioned and supported by the limit component and enter the cutting stage without intermediate transfer. At the same time, the main machine box can coordinate the operation rhythm of motor one, motor two and motor three to achieve the matching of the cycle of pipe bending and cutting, which greatly shortens the production cycle and reduces transfer costs and positioning deviation risks.

The same reference numerals in the drawings denote elements that have the same or similar functions. Although various aspects of the embodiments are shown in the drawings, they are not necessarily drawn to scale unless specifically indicated otherwise.

[0033] The term “exemplary” as used herein means “serving as an example, embodiment, or illustration.” Any embodiment illustrated herein as “exemplary” is not necessarily to be construed as superior to or better than other embodiments.

[0034] Furthermore, to better illustrate this disclosure, numerous specific details are set forth in the following detailed description. Those skilled in the art will understand that this disclosure can be practiced without certain specific details. In some instances, methods, means, components, and circuits well known to those skilled in the art have not been described in detail in order to highlight the main points of this disclosure.

[0035] Reference Figures 1-9 As shown in this embodiment, a mechanical cutting device for pipe bending production integrates pipe bending and cutting functions, enabling integrated "pipe bending-cutting" operations and reducing intermediate transfer links. The device includes a pipe bending machine housing 1, which serves as an overall support frame, providing a mounting base for each component. Vertical plates 101 are symmetrically arranged at the front and back of the housing. Sheet metal cover plates 1011 are bolted to the top of the vertical plates 101 on both sides. This fixed connection method ensures the protective function of the sheet metal cover plates 1011 on the top of the vertical plates 101, while also providing stable support for the components above.

[0036] The top center of the sheet metal cover plate 1011 is fixedly connected to the main unit housing 102. The main unit housing 102 integrates a control module to provide control support for the subsequent coordinated operation of the motor. The top of the bending machine housing 1 is also equipped with two sets of rollers 103. The bottom of the two sets of rollers 103 extends into the interior of the bending machine housing 1 and is connected to the motor. This transmission connection method ensures that the motor can drive the rollers 103 to rotate stably, thereby transporting the unbent pipe products to the bending operation area.

[0037] A fixing component 104 is fixedly installed on the front side of the pipe bending machine housing 1 by welding. The top of the fixing component 104 is bolted to the fixing seat 105. This connection method facilitates the subsequent adjustment or maintenance of the position of the fixing seat 105. The fixing seat 105 is fixedly connected to the motor 106. The rotating shaft of the motor 106 is fixedly connected to the pipe bending protrusion 107. The pipe bending protrusion 107 is fitted with a roller shaft 2. The presence of the motor 106 allows the position of the pipe bending protrusion 107 to be controlled by adjusting the rotating shaft angle, thereby changing the contact angle between the roller shaft 2 and the pipe and realizing the adjustment of different pipe bending arcs.

[0038] The upper right side of the pipe bending machine housing 1 is bolted to the fixed base 201, and the fixed base 201 is fixedly connected to the limiting component 202. The limiting component 202 includes a base plate 2021, the top center of the base plate 2021 is welded to the support column base 2022 on both the front and rear sides, and the top four corners of the base plate 2021 are fixedly connected to bolt columns 2025. U-shaped connectors 2023 are fitted on the two bolt columns 2025 on one side. The top of the U-shaped connectors 2023 is symmetrically welded to the rotating shaft plate 2024. A rotating shaft is fitted on the rotating shaft, and a roller 2026 is fitted on the rotating shaft. Roller 2027 is movably installed on the support column bases 2022 on both the front and rear sides. The cooperation between roller 1026 and roller 2027 can limit the product after bending and provide stable support for subsequent cutting operations, avoiding pipe shaking that affects cutting accuracy.

[0039] The bottom right side of the pipe bending machine housing 1 is fixedly connected to the base plate 1012. The left and right sides of the base plate 1012 are welded to the support plate 401. The top and bottom of the left and right support plates 401 are bolted to the connecting beam 1 403 and connecting beam 2, respectively. This frame structure can enhance the stability of the support plate 401 and avoid severe vibration during cutting operations. The middle part of the support plate 401 is fixedly connected to the cutting chassis 402 by bolts. The left support plate 401 is fixedly connected to the motor 3 4067 by bolts. The center of the cutting chassis 402 in the horizontal direction is fixedly connected to the lead screw 404. The left end of the lead screw 404 extends to the outside of the left support plate 401 and is fixedly connected to the bearing 1. The bearing 1 is fixedly connected to the roller 405. The roller 1 405 is connected to the roller 2 on the shaft of the motor 3 4067 by belt drive. This transmission method ensures that the motor 3 4067 can drive the roller 1 405 to rotate, thereby driving the lead screw 404 to rotate.

[0040] A cutting base 408 is movably mounted on the lead screw 404. The top of the front and rear sides of the cutting base 402 is fixedly connected to the guide rail 407. Guide rail grooves are provided on the bottom of both the front and rear sides of the cutting base 408, and these grooves slide against the guide rail 407. This fit restricts the movement trajectory of the cutting base 408, ensuring smooth left and right movement along the lead screw 404. A cutting assembly 406 is mounted on the cutting base 408. The cutting assembly 406 includes a base 4062, which is fixedly connected to a transmission pulley 4063. The left side of the 063 is connected to the servo motor 4061, and the right side of the transmission pulley 4063 is fixedly connected to the cutting disc 4064. The servo motor 4061 can provide stable power to the transmission pulley 4063, thereby driving the cutting disc 4064 to rotate to achieve cutting operations. The bottom of the transmission pulley 4063 is also provided with a buffer rod 4065 and a safety component 4066. The safety component 4066 includes a cylinder and a fixed rod, which can drive the transmission pulley 4063 to rotate around the front shaft in an emergency to transfer the cutting disc 4064 to avoid danger.

[0041] The rear side of the cutting base 408 is fixedly connected to the main unit housing 409 by bolts. The top center of the main unit housing 409 is fixedly connected to the linear motor 410. The left and right sides of the top of the cutting base 408 are fixedly connected to the guide rail 412. The bottom of the base 4062 is provided with multiple sets of guide rail recesses 413. The guide rail 412 and the guide rail recesses 413 are slidably engaged. The top of the telescopic rod of the linear motor 410 is fixedly connected to the bottom center of the base 4062. This connection method allows the linear motor 410 to drive the base 4062 to move along the direction of the guide rail 412, thereby adjusting the vertical position of the cutting disc 4064. In addition, the side of the base 4062 is fixedly connected to the triangular metal piece 416, and the side of the cutting base 408 is fixedly connected to the slide rod 414. A displacement sensor 415 is movably mounted on the slide rod 414 and is fixedly connected to the triangular metal piece 416. The bottom front side of the cutting base 408 is fixedly connected to the slide rod 417. A displacement sensor 411 is movably mounted on the slide rod 417 and is fixedly connected to the bottom of the front side plate of the cutting base 408. The two displacement sensors can send real-time displacement data to the main unit 409, providing data support for the main unit 409 to accurately control the cutting component 406. At the same time, the main unit 102 is electrically connected to motor 1, motor 2 106, and motor 3 4067, which can coordinately control the operating rhythm of each motor to achieve the matching of the cycle time of pipe bending and cutting operations.

[0042] In some examples, both main unit chassis 1 (409) and main unit chassis 2 (102) have ventilation holes on their sides and are equipped with small cooling fans inside. The cooling fans are electrically connected to the internal temperature sensor. When the internal temperature exceeds the preset value, the cooling fans will start automatically to quickly dissipate the heat inside the chassis, preventing the control module from malfunctioning due to high temperature and ensuring the stable operation of the device.

[0043] In some examples, the cutting assembly 406 is provided with a removable protective cover on the outside. The protective cover is connected to the cutting base 408 by a snap-fit. This design can prevent metal chips from flying during cutting operations, protect the operator's safety, and also facilitate subsequent disassembly and cleaning of chips.

[0044] In some examples, the surface of guide rail 412 is engraved with positioning scale lines, which can help operators quickly calibrate the position when installing or adjusting the cutting component 406, reducing the time cost of manual calibration and improving debugging efficiency.

[0045] The working principle of this invention is:

[0046] When using this mechanical cutting device for pipe bending production, preliminary preparation and parameter setting are required. First, check the connection status of each core component of the device: confirm that the bolts connecting the top vertical plate 101 of the pipe bending machine housing 1 to the sheet metal cover plate 1011 are secure, the transmission relationship between motor 1, motor 2 106, motor 3 4067 and their corresponding transmission components is normal, the rollers 1 2026 and 2027 of the limit assembly 202 rotate flexibly, and the buffer rod 4065 and safety assembly 4066 of the cutting assembly 406 are not stuck. Then, set the core parameters through the main housing 2 102 on the top of the sheet metal cover plate 1011: preset the bending curvature according to the pipe diameter and material, input the cutting dimensions through the main housing 1 409, and simultaneously calibrate the initial zero points of displacement sensors 1 415 and 2 411 to ensure data feedback accuracy.

[0047] After preparation, the pipe bending operation begins. The main unit 102 starts motor 1, which drives two sets of rollers 103 to rotate, conveying the unbent pipe along the top of the bending machine 1 to the bending protrusion 107. At this time, the main unit 102 controls motor 106 to operate. The shaft of motor 106 drives the bending protrusion 107 to adjust to a preset angle, and roller 2 on the bending protrusion 107 contacts the pipe surface. As roller 103 continues to convey the pipe, roller 2 applies a lateral force during the pipe's movement, causing the pipe to bend along the arc of the bending protrusion 107. The bent pipe continues to be conveyed to the right-side limiting assembly 202. Roller 2026 and roller 2027 on the base plate 2021 form a bidirectional limiting mechanism, preventing pipe deviation and providing stable support for subsequent cutting operations, achieving a seamless connection from bending to support.

[0048] After the pipe bending operation is completed, the system automatically switches to the cutting operation stage. The main unit 102 synchronously starts motor 4067 (motor 3) and servo motor 4061 (cutting assembly 406). The shaft of motor 4067 drives roller 2 to rotate, which in turn drives roller 405 (outer side of left support plate 401) to rotate via belt drive. Roller 405 (roller 405) drives the lead screw 404 (center of cutting base 402) to rotate via bearing 1. When the lead screw 404 rotates, the cutting base 408 moves smoothly along the direction of the lead screw 404 to the position to be cut on the pipe through the sliding engagement of the bottom guide rail groove with guide rail 407. Simultaneously, servo motor 4061 drives transmission pulley 4063 to rotate, and the cutting disc 4064 (right side of transmission pulley 4063) rotates synchronously at high speed. The main unit 109 controls linear motor 410 to operate, and the extension rod of linear motor 410 drives the base 4062 (base of cutting assembly 406) to move up and down, adjusting the cutting depth of the cutting disc 4064. During this process, displacement sensor 415 moves with base 4062 and collects vertical displacement data in real time; displacement sensor 411 moves with cutting base 408 and captures horizontal displacement data. The two sets of data are transmitted synchronously to main unit 409. Main unit 409 dynamically adjusts the operating rhythm of linear motor 410 and motor 4067 according to preset parameters to ensure that cutting disc 4064 accurately removes excess parts of the pipe and avoids dimensional errors caused by pipe deformation and equipment vibration.

[0049] When equipment failure or emergency occurs, the device's safety protection mechanism is activated. After receiving a signal from the main unit 409, the safety component 4066 at the bottom of the cutting assembly 406 pushes the fixed rod to rotate the transmission pulley 4063 around the front shaft, quickly transferring the cutting disc 4064 to the non-working area to avoid collision between the cutting disc 4064 and the pipe or equipment components. At the same time, the buffer rod 4065 can alleviate the sudden impact force during cutting, reduce the wear of the connection between the transmission pulley 4063 and the base 4062, and ensure the safety of the core components of the equipment.
