A pipe production flat mouth machine

Abstract

This invention relates to the field of pipe-ending machine technology, specifically to a pipe-ending machine, comprising a worktable with an isolation frame on its surface. The worktable is hollow with an open bottom, and the isolation frame has a through groove at its top. A top frame is provided above the isolation frame, and a support frame is provided on the side of the worktable away from the isolation frame. A pulley table is provided on the surface of the support frame, and limiting components are provided on both sides of the pulley table. After the pipe-ending cutting operation is completed, the output end of the control rotating motor drives the lead screw to rotate in the opposite direction. When the lead screw rotates, it drives the moving seat to move away from the pipe. At this time, the pull rope wrapped around the surface of the collecting roller gradually loosens, and the traction force on the moving rod decreases, thereby causing the moving rod to drive the baffle to slowly move downward in the vertical direction. During the downward movement of the baffle, the waste material generated by pipe cutting is pushed by the pipe-ending blade to coil around the inner wall of the isolation frame, causing the waste material to fall below the isolation frame, thereby improving the efficiency of the pipe-ending cutting operation.

Description

Technical Field

[0001] This invention relates to the field of pipe finishing machine technology, and in particular to a pipe finishing machine for pipe production. Background Technology

[0002] Pipe finishing machines can process the ends of thin-walled metal pipes into weldable cuts without burrs. They are used to cut the end of stainless steel pipes that needs processing, creating a smooth cut and making the pipe more aesthetically pleasing. Pipe finishing machines are now widely used for this processing operation.

[0003] There are many existing technologies for edge finishing machines, such as:

[0004] Chinese invention patent CN218745178U discloses a pipe-end finishing machine, including a frame; a mounting base is provided at one end of the frame; a first motor is provided above the mounting base at the end away from the frame; the first motor is fixedly mounted on the mounting base via a motor bracket; the first motor is connected to a fixed bearing via a first coupling; the fixed bearing is fixedly connected to the motor bracket via a sliding rod bracket; a reducer mounting base is provided at the end of the frame away from the first motor; a reducer is mounted on the reducer mounting base; the reducer is fixedly connected to a second motor; a fixed shaft is provided on the surface of the reducer adjacent to the second motor; the fixed shaft is fixedly connected via a second coupling; multiple blades are provided on the surface of the fixed shaft; in this device, the pipe is clamped by grippers, and the motor drives the lead screw to rotate, realizing the approach or distance between the pipe and the blades, thereby achieving pipe end finishing.

[0005] However, some problems still exist in actual use:

[0006] 1. The existing pipe end flat cutting operation requires manual operation by the operator. During the cutting operation, the waste generated will be at a high temperature. The operator is likely to come into contact with the high temperature waste during operation, which may cause burn accidents and pose a serious threat to the personal safety of the operator.

[0007] 2. During pipe end cutting, the waste generated at the pipe end is prone to entanglement and accumulation inside the isolation frame of the cutting equipment, which cannot be automatically discharged. This not only interferes with the smooth progress of subsequent end cutting operations, affecting cutting accuracy and work continuity, but also requires operators to stop work for manual cleaning, which greatly increases the labor intensity of operators and reduces overall production efficiency. Summary of the Invention

[0008] In order to overcome the above-mentioned defects in the prior art, the present invention provides a pipe-making flat-end machine.

[0009] To achieve the above objectives, the present invention provides a pipe end-cutting machine, comprising a worktable, an isolation frame on the surface of the worktable, the worktable being hollow with an open bottom, a through groove on the top of the isolation frame, a top frame above the isolation frame, a support frame on the side of the worktable away from the isolation frame, a pulley table on the surface of the support frame, and limiting components on both sides of the pulley table for limiting the pipe placed on the pulley table surface to be centered on the pulley table. A feeding component is provided on the top of the support frame for pushing the pipe to move on the pulley table surface and fixing it when it moves below the through groove. A pipe end-cutting component is provided inside the isolation frame, which moves horizontally inside the isolation frame to control the pipe end's end-cutting feed size. A waste removal component is provided below the through groove for positioning the pipe end to keep the pipe end position consistent during the pipe end-cutting process. Simultaneously, after the pipe end-cutting is completed, as the pipe end-cutting component moves away from the pipe, it drives the waste removal component to remove pipe debris entangled in the isolation frame.

[0010] Furthermore, the limiting component includes column barrels disposed on both sides of the pulley table, a sliding rod is slidably disposed on the inner wall of the column barrel, an elastic element is disposed between the column barrel and the sliding rod, and a limiting plate is disposed at the end of the elastic element.

[0011] Furthermore, the feeding assembly includes an electric telescopic rod located on the top of the support frame. The end of the electric telescopic rod passes through the support frame and has a support plate at the end. The support plate has a drive wheel inside. The electric telescopic rod is controlled to drive the support plate to move in the vertical direction. When the drive wheel inside the support plate is in contact with the outer wall of the pipe, the drive wheel is controlled to rotate, causing the pipe to move horizontally on the surface of the pulley table.

[0012] Furthermore, cylinders are provided on both sides of the support plate, and a pressure plate is provided on the piston rod at the end of the cylinder. When the pipeline moves to the designated position, the piston rod at the end of the cylinder is controlled to drive the pressure plate to move down and press and fix the pipeline.

[0013] Furthermore, the flat-end cutting assembly includes a rotary motor located on one side of the workbench, a lead screw at the output end of the rotary motor, a movable seat on the surface of the lead screw, and the movable seat moving on its surface when the lead screw rotates. The movable seat moves inside the isolation frame, and a flat-end blade is provided at the end of the movable seat. The flat-end blade is used to perform flat-end cutting operations on the end of the pipe.

[0014] Furthermore, the top of the movable seat is provided with a rack, which extends through the isolation frame into the interior of the top frame. Above the rack is a waste removal component, which is used to position the end of the pipe so that the end position of the pipe remains the same during the flat-end cutting process.

[0015] Furthermore, the waste removal assembly includes a hollow barrel located at the top of the top frame, a movable rod slidably disposed on the inner wall of the hollow barrel, a telescopic spring disposed between the hollow barrel and the movable rod, and a baffle disposed at the end of the movable rod, the baffle being in the shape of a cutter disc.

[0016] Furthermore, a gear rod is provided at the bottom of the top frame, and a collecting roller is provided on the surface of the gear rod. When the rack moves, it drives the gear rod to mesh and rotate. A pull rope is provided at the end of the moving rod away from the baffle. The free end of the pull rope is fixed to the surface of the collecting roller. A fixed pulley group is provided at the top of the top frame, and the pull rope moves along the surface of the fixed pulley group.

[0017] Furthermore, hollow grooves are provided on both sides of the baffle, and a support rod is provided inside the hollow groove. A rotating plate is rotatably provided on the surface of the support rod, and a torsion spring is provided between the support rod and the rotating plate. The rotating plate is subjected to the force of the torsion spring and forms a 30° angle with the horizontal.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0019] 1. In this pipe-making end-cutting machine, when the pipe is being fed, the moving rod slides against the inner wall of the hollow barrel under the force of the telescopic spring. The moving rod drives the baffle to move to the center of the isolation frame. Through the friction of the drive wheel, the pipe moves horizontally on the surface of the pulley table. When the pipe end moves to the end of the baffle, it is blocked, so that all pipes are in the same position during the end-cutting operation. The feed length of the end-cutting blade is controlled to perform the end-cutting operation, thereby ensuring that the pipe ends are the same size after end-cutting and improving the dimensional accuracy of the pipe products after end-cutting.

[0020] 2. In this pipe-making flat-end cutting machine, after the flat-end cutting is completed, the output end of the control rotating motor drives the lead screw to rotate in the opposite direction. When the lead screw rotates, it drives the moving seat to move away from the pipe. At this time, the pull rope wrapped around the surface of the collecting roller gradually loosens, and the traction force on the moving rod decreases, so that the moving rod drives the baffle to move slowly downward in the vertical direction. During the downward movement of the baffle, the waste generated by pipe cutting is pushed by the flat-end cutter to coil around the inner wall of the isolation frame, so that the waste falls through the bottom of the isolation frame, thereby improving the efficiency of the flat-end cutting operation.

[0021] 3. In this pipe-making flat-end machine, when the moving rod drives the baffle to move vertically upward, the rotating plate is squeezed and rotates on the surface of the support rod by the isolation frame, which reduces the distance between the arms of the rotating plates. When the moving rod drives the baffle to move vertically downward, the arms between the rotating plates are in an unfolded state due to the force of the torsion spring. When the rotating plate cooperates with the baffle, the waste cleaning area increases, which improves the waste cleaning efficiency. Attached Figure Description

[0038] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0039] A pipe-ending machine, according to Figure 1-9 As shown, the system includes a workbench 100, with an isolation frame 101 on its surface. The workbench 100 is hollow with an open bottom. A through slot 102 is formed at the top of the isolation frame 101. A top frame 103 is provided above the isolation frame 101. A support frame 104 is provided on the side of the workbench 100 away from the isolation frame 101. A pulley table 105 is provided on the surface of the support frame 104. Limiting components 200 are provided on both sides of the pulley table 105. The limiting components 200 are used to limit the pipes placed on the surface of the pulley table 105 so that they are located at the center of the pulley table 105. A feeding component 300 is provided at the top of the support frame 104. The feeding component 300 is used to push... The moving pipe moves on the surface of the pulley table 105 and is fixed when it moves below the through groove 102. A flat-end cutting component 400 is provided inside the isolation frame 101. The flat-end cutting component 400 moves horizontally inside the isolation frame 101 to control the flat-end feed size of the pipe end. A waste removal component 500 is provided below the through groove 102. The waste removal component 500 is used to position the pipe end so that the pipe end position remains the same during the flat-end cutting process. At the same time, after the flat-end cutting of the pipe is completed, when the flat-end cutting component 400 moves away from the pipe, it drives the waste removal component 500 to remove the pipe waste debris wrapped in the isolation frame 101.

[0040] During the flat-end cutting of pipes, in order to prevent the pipes from slipping and thus affecting the pipe feeding efficiency, the limiting component 200 includes column barrels 201 on both sides of the pulley table 105. A sliding rod 202 is slidably provided on the inner wall of the column barrel 201. An elastic element 203 is provided between the column barrel 201 and the sliding rod 202. A limiting plate 204 is provided at the end of the elastic element 203. When the pipe is flat-end cut, it is placed on the surface of the pulley table 105. The outer wall of the pipe is in contact with the end face of the limiting plate 204 and is squeezed. When the limiting plate 204 is under pressure, the sliding rod 202 at its end slides on the inner wall of the column barrel 201 and squeezes the elastic element 203. At this time, the pipe is pushed to move horizontally. The pipe is limited by the limiting plate 204 and is centered, preventing the pipe from slipping on the surface of the pulley table 105, thereby improving the pipe feeding efficiency.

[0041] Considering that during the mass production of pipes, operators need to load multiple pipes, which increases the labor intensity of the operators, the loading component 300 includes an electric telescopic rod 301 located on the top of the support frame 104. The end of the electric telescopic rod 301 passes through the support frame 104 and has a support plate 302 at its end. The support plate 302 has a drive wheel 303 inside. By controlling the electric telescopic rod 301, the support plate 302 is moved vertically. When the drive wheel 303 inside the support plate 302 is in contact with the outer wall of the pipe, the drive wheel 303 is rotated to move the pipe horizontally on the surface of the pulley table 105. By controlling the electric telescopic rod 301, the support plate 302 is moved vertically downward. When the drive wheel 303 is in contact with the top of the pipe, the drive wheel 303 consists of a servo motor and a friction roller located at its output end. The servo motor drives the friction roller to rotate, and the rotation of the friction roller drives the pipe to move horizontally for loading operations, thereby reducing the labor intensity of the operators.

[0042] When the pipe is loaded, it is necessary to ensure the stability of the pipe and the smoothness of the pipe end during the flat cutting operation. Therefore, cylinders 304 are provided on both sides of the support plate 302, and pressure plates 305 are provided on the piston rods at the ends of the cylinders 304. When the pipe moves to the designated position, the piston rods at the ends of the cylinders 304 on both sides of the electric telescopic rod 301 are controlled to drive the pressure plates 305 to move down and press and fix the pipe. When the pipe loading is completed, the piston rods at the ends of the cylinders 304 are controlled to drive the pressure plates 305 to move down vertically until the pressure plates 305 move down to fit tightly against the pipe surface. The pressure plates 305 press and fix the pipe, ensuring the stability of the pipe during the flat cutting, thereby keeping the pipe at the flat cutting position smooth and improving the flat cutting quality.

[0043] When performing a flat-end cutting on the pipe end, operators are required to perform the cutting operation. During the cutting process, the waste chips are at a high temperature, which can easily cause burns. Therefore, the flat-end cutting assembly 400 includes a rotary motor 401 located on one side of the workbench 100. The output end of the rotary motor 401 is equipped with a lead screw 402, and a movable seat 403 is provided on the surface of the lead screw 402. When the lead screw 402 rotates, it drives the movable seat 403 to move on its surface. The movable seat 403 moves inside the isolation frame 101. A flat-end cutting blade 404 is provided at the end of the movable seat 403. The flat-end cutting blade 404 is used to cut the pipe end... The pipe end is subjected to flat-edge cutting. The output of the rotating motor 401 drives the lead screw 402 to rotate. When the lead screw 402 rotates, it drives the moving seat 403 on its surface to move horizontally. The end of the moving seat 403 is equipped with a flat-edge cutter 404. When the flat-edge cutter 404 approaches and fits against the end of the pipe, the feed parameters are set, and the moving seat 403 is controlled to drive the flat-edge cutter 404 to move horizontally to perform automatic flat-edge cutting on the end of the pipe. At the same time, the isolation frame 101 blocks the waste generated by the flat-edge cutting to prevent it from splashing, thereby ensuring the safety of the pipe production process.

[0044] In the pipeline production process, to ensure the consistency of pipeline dimensions after the end-cutting operation, it is necessary to set the feed length for end-cutting to improve the accuracy of end-cutting. A rack 405 is provided on the top of the moving seat 403, penetrating the isolation frame 101 to the interior of the top frame 103. A waste removal component 500 is provided above the rack 405. The waste removal component 500 is used to position the pipeline end, ensuring that the end position of the pipeline remains consistent during end-cutting. The waste removal component 500 includes a hollow barrel 501 located on the top of the top frame 103. A moving rod 502 is slidably mounted on the inner wall of the hollow barrel 501, and a telescopic spring 503 is provided between the hollow barrel 501 and the moving rod 502. The end of the moving rod 502 is provided with a baffle 504, which is shaped like a cutter disc. When feeding the pipe, the moving rod 502 slides on the inner wall of the hollow barrel 501 under the force of the telescopic spring 503. The moving rod 502 drives the baffle 504 to move to the center of the isolation frame 101. The pipe moves horizontally on the surface of the pulley table 105 through the friction of the drive wheel 303. When the flat end of the pipe moves to the end of the baffle 504, it is blocked, so that all pipes are in the same position during the flat end operation. The feed length of the flat end cutter 404 is controlled to perform the flat end cutting operation, thereby ensuring that the pipes are the same size after flat end cutting and improving the dimensional accuracy of the pipe products after flat end cutting.

[0045] When cutting pipes, waste generated from the flat-end cutting of the pipe ends easily gets tangled inside the isolation frame 101, affecting subsequent flat-end cutting operations. This requires cleaning by operators, reducing production efficiency. Therefore, a gear rod 507 is provided at the bottom of the top frame 103, and a collecting roller 508 is provided on the surface of the gear rod 507. When the rack 405 moves, it drives the gear rod 507 to mesh and rotate. A pull rope 505 is provided at the end of the moving rod 502 away from the baffle 504, and the free end of the pull rope 505 is fixed to the collecting roller 508. On the surface of the 08, a fixed pulley group 506 is provided on the top of the top frame 103. The pull rope 505 moves along the surface of the fixed pulley group 506. When it is necessary to perform a flat-end cutting operation on the pipe, the output end of the control rotation motor 401 drives the lead screw 402 to rotate. The movable seat 403 provided on the surface of the lead screw 402 drives the flat-end cutter 404 to move horizontally. During the movement of the movable seat 403, it drives the rack 405 to move. When the rack 405 moves, it drives the gear rod 507 to mesh and rotate. When the gear rod 507 rotates, it drives the collecting roller. When the collecting roller 508 rotates coaxially, it winds the pull rope 505. The pull rope 505, under tension, causes the moving rod 502 to slide against the inner wall of the hollow barrel 501. During its movement, the moving rod 502 moves the baffle 504 away from the interior of the isolation frame 101, thus preventing it from obstructing the flat-edge cutting operation of the flat-edge cutter 404 and ensuring the normal operation of the flat-edge cutting. After cutting is completed, the output of the control motor 401 drives the lead screw 402 to rotate in the opposite direction. When rod 402 rotates, it drives moving seat 403 away from the pipe. At this time, the pull rope 505 wrapped around the surface of collecting roller 508 gradually loosens, and the traction force on moving rod 502 decreases. As a result, moving rod 502 drives baffle 504 to move slowly downward in the vertical direction. During the downward movement of baffle 504, the waste generated by pipe cutting is pushed by flat blade 404 to coil around the inner wall of isolation frame 101, so that the waste falls below isolation frame 101, thereby improving the efficiency of flat cutting operation.

[0046] To improve cleaning efficiency when cleaning waste generated during flat-edge cutting, hollow grooves 509 are provided on both sides of the baffle 504. Support rods 510 are installed inside the hollow grooves 509, and rotating plates 511 are rotatably mounted on the surface of the support rods 510. A torsion spring 512 is installed between the support rods 510 and the rotating plates 511. The rotating plates 511 are at a 30° angle to the horizontal due to the force exerted by the torsion spring 512. Under normal circumstances, when the moving rod 502 moves the baffle 504 vertically, the rotating plates 511 are squeezed and rotated on the surface of the support rods 510 by the isolation frame 101, reducing the distance between the arms of the rotating plates 511. When the moving rod 502 moves the baffle 504 vertically downward, the arms between the rotating plates 511 are extended due to the force exerted by the torsion spring 512. The area for cleaning waste increases when the rotating plates 511 cooperate with the baffle 504, thus improving the waste cleaning efficiency.

[0047] In practical use, the pipe is placed on the surface of the pulley table 105, and the outer wall of the pipe is pressed against the end face of the limiting plate 204. When the limiting plate 204 is under pressure, the sliding rod 202 at its end slides on the inner wall of the column barrel 201 and presses the elastic element 203. At this time, the pipe is pushed to move horizontally. The pipe is limited by the limiting plate 204 and is centered, which prevents the pipe from sliding on the surface of the pulley table 105, thereby improving the efficiency of pipe feeding. By controlling the electric telescopic rod 301 to drive the support plate 302 to move downward in the vertical direction, when the drive wheel 303 is in contact with the top of the pipe, the drive wheel 303 is controlled to rotate to drive the pipe to move horizontally for feeding operations, thereby reducing the labor intensity of the operators.

[0048] When the pipe feeding is completed, the piston rod at the end of the control cylinder 304 drives the pressure plate 305 to move down in the vertical direction until the pressure plate 305 moves down to fit tightly against the pipe surface. The pressure plate 305 presses and fixes the pipe to ensure the stability of the pipe during flat cutting, thereby keeping the pipe cutting position smooth and improving the quality of flat cutting.

[0049] The output of the control motor 401 drives the lead screw 402 to rotate. When the lead screw 402 rotates, it drives the movable seat 403 on its surface to move horizontally. The end of the movable seat 403 is equipped with a flat blade 404. When the flat blade 404 approaches and fits against the end of the pipe, the feed parameters are set, and the movable seat 403 is controlled to drive the flat blade 404 to move horizontally to perform a flat cutting operation on the end of the pipe, thereby ensuring safety in the pipe production process.

[0050] When feeding the pipe, the moving rod 502 slides on the inner wall of the hollow barrel 501 under the force of the telescopic spring 503. The moving rod 502 drives the baffle 504 to move to the center of the isolation frame 101. The driving wheel 303 drives the pipe to move horizontally on the surface of the pulley table 105 through friction. When the flat end of the pipe moves to the end of the baffle 504, it is blocked, so that all pipes are in the same position when the flat end is operated. The feed length of the flat end cutter 404 is controlled to perform the flat end cutting operation, thereby ensuring that the pipes are the same size after the flat end is cut and improving the dimensional accuracy of the pipe products after the flat end is cut.

[0051] When a pipe needs to be cut at the flat end, the output of the control motor 401 drives the lead screw 402 to rotate. The movable seat 403 on the surface of the lead screw 402 drives the flat-end cutter 404 to move horizontally. During the movement of the movable seat 403, the rack 405 moves. When the rack 405 moves, it drives the gear rod 507 to mesh and rotate. When the gear rod 507 rotates, it drives the collecting roller 508 to rotate coaxially. When the collecting roller 508 rotates, it winds the pull rope 505. The pull rope 505 is under tension, which causes the movable rod 502 to slide on the inner wall of the hollow barrel 501. During the movement of the movable rod 502, it moves the baffle 504 away from the interior of the isolation frame 101, thereby preventing the flat-end cutter 404 from being blocked by the baffle 504 during the flat-end cut, ensuring the flat end is cut. The cutting operation proceeds normally. After the cutting is completed, the output of the control motor 401 drives the lead screw 402 to rotate in the opposite direction. When the lead screw 402 rotates, it drives the moving seat 403 to move away from the pipe. At this time, the pull rope 505 wrapped around the surface of the collecting roller 508 gradually loosens, and the traction force on the moving rod 502 decreases. As a result, the moving rod 502 drives the baffle 504 to slowly move down in the vertical direction. During the downward movement of the baffle 504, the waste generated by the pipe cutting is pushed by the flat blade 404 to coil around the inner wall of the isolation frame 101, so that the waste falls through the bottom of the isolation frame 101, thereby improving the efficiency of the flat cutting operation. At the same time, the isolation frame 101 blocks the waste generated by the flat cutting to prevent it from splashing and improve the safety of the operation.

[0052] When the moving rod 502 drives the baffle 504 to move vertically, the rotating plate 511 is squeezed and rotated on the surface of the support rod 510 by the isolation frame 101, which reduces the distance between the arms of the rotating plates 511. When the moving rod 502 drives the baffle 504 to move vertically downward, the arms between the rotating plates 511 are in an unfolded state due to the force of the torsion spring 512. The rotating plates 511 cooperate with the baffle 504 to increase the area for cleaning waste and improve the efficiency of cleaning waste.
