Description

Technical Field

[0001] This utility model relates to the field of steel pipe positioning and cutting technology, and in particular to a steel pipe cutting and positioning device. Background Technology

[0002] During the steel pipe cutting process, the kinetic energy generated by the cutting machine blade is applied to the steel pipe. When the steel pipe comes into contact with the cutting blade, it is subjected to vibration and centrifugal force from the cutting blade. The user is also affected by vibration and centrifugal force when controlling the pipe fitting. Since manual control of the pipe fitting is unstable, the steel pipe is still subject to vibration, which causes errors in the cutting angle. This results in an uneven end face of the cut steel pipe, which greatly affects subsequent connection with other steel pipes and welding of joints. Large gaps will appear at the joints, reducing the sealing performance of the pipe fitting, reducing the strength of the pipe joint, and shortening the service life of the pipe fitting.

[0003] To address the aforementioned problems, this utility model provides improvements. Summary of the Invention

[0004] This utility model proposes a steel pipe cutting and positioning device, which solves the above-mentioned problems existing in the use of the prior art.

[0005] The technical solution of this utility model is implemented as follows: A steel pipe cutting and positioning device includes a base, a workbench is fixedly installed at one end of the top of the base, and a support frame is fixedly installed at one end of the bottom of the workbench. A motor is fixedly installed at one end of the top of the support frame, and a cutting blade is fixedly installed at the output end of one side of the motor. A placement plate is movably installed at one end of the top of the workbench, and a fixing block is fixedly installed at one end of the bottom of the placement plate. A rotating shaft is rotatably installed inside the fixing block, and a first gear is fixedly installed at both ends of the rotating shaft. Threads are provided on both sides of the rotating shaft surface, and sliders are movably installed on both sides of the rotating shaft. A positioning block is fixedly installed at one end of the top of the slider, and a limiting groove matching the steel pipe is opened on the inner side of the positioning block. A first rack matching the first gear is fixedly installed on both sides of the bottom of the workbench.

[0006] The present invention, as described above, is used for a steel pipe cutting and positioning device. Further, a second rack is fixedly installed on one side of the bottom of the placement plate, support plates are fixedly installed on both sides of the top of the workbench, and a first rotating rod is movably installed inside the support plate. A second gear matching the second rack is movably installed on the outer side of the first rotating rod. A second rotating rod is movably installed on the inner side of the top of the support plate, and a baffle is fixedly installed at one end of the second rotating rod. A hinge cover is fixedly installed at one end of the second rotating rod to restrict its movement.

[0007] The present invention provides a steel pipe cutting and positioning device as described above, further comprising: a pulley fixedly installed at one end of both the first rotating rod and the second rotating rod, a belt sleeved at one end of the pulley, and the second rotating rod and the first rotating rod connected by the belt.

[0008] The present invention provides a steel pipe cutting and positioning device as described above, further comprising: the baffle is made of chlorinated polyether and the interior of the baffle is hollow.

[0009] The present invention provides a steel pipe cutting and positioning device as described above, further comprising: a second movable groove for moving a slider is symmetrically provided at one end of the worktable; a first movable groove for moving a slider is provided inside the placement plate; and a placement groove is provided inside the placement plate.

[0010] The present invention provides a steel pipe cutting and positioning device as described above, further comprising: a connecting block fixedly installed at one end of the placement plate, and a handle fixedly installed at one end of the bottom of the connecting block; and a cutting groove for moving the connecting block is provided in the middle of the workbench.

[0011] The present invention provides a steel pipe cutting and positioning device as described above, further comprising: the slider having a threaded groove matching the thread, and the two sets of threads being arranged in opposite directions.

[0012] In summary, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model, by setting a clamping and positioning structure, has two sets of positioning blocks that move in opposite directions to clamp, position, and fix the horizontally placed pipe. When subjected to vibration, the positioning blocks can ensure that they provide clamping force to the steel pipe and maintain sufficient stability under vibration, thereby ensuring that the cut surface of the steel pipe is flush after cutting. This helps the finished steel pipe and the welded parts to fit better, improves the sealing performance of the pipe fitting during installation and use, increases the strength of the welded joint of the pipe fitting, and extends the service life of the pipe fitting.

[0014] 2. This utility model effectively ensures that the second rotating rod will not be affected by the gravity of the cover itself and thus will not be angularly offset. The placement plate provides support and fixation for the second rack. At the same time, the placement plate and the second rack provide a power source for the rotation of the second gear. The rotation of the cover causes its angle to change and move closer to the cutting position, thereby blocking the waste generated by cutting to a certain extent and ensuring the safety of the working environment.

[0015] 3. By setting a belt and pulley, this utility model makes the transmission effect more stable, and at the same time can control the baffle to ensure that the baffle does not occupy extra space when it is not in use, which facilitates the placement of steel pipes.

[0016] 4. The chlorinated polyether material baffle of this utility model can withstand higher temperatures and will not deform even after being exposed to high-temperature waste for a long time. At the same time, the hollow baffle can limit the direction and distance of waste splashing to a greater extent, thus effectively protecting workers.

[0017] 5. This utility model provides a certain space for the slider to move inside the worktable through the second movable groove, while restricting it to ensure that it can move along a predetermined route during the movement. The opening of the first movable groove provides space for the slider to move inside the placement plate, ensuring that the slider has enough position to move when driven by the rotating shaft, thereby ensuring that the positioning block can properly restrict the pipe to be fixed.

[0018] 6. This utility model provides a certain space for the connecting block to move inside the worktable through the cutting groove, while restricting it to ensure that its movement direction will not deviate.

[0019] 7. This utility model uses a threaded design, allowing the slider to move a certain distance via the thread. The opposing threads allow two sets of positioning blocks to move in opposite directions and converge towards the center, thereby achieving the purpose of fixing the pipe.

[0028] The following will refer to the appendix in the embodiments of this utility model. Figure 1-5 The technical solutions in the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model. Example

[0029] A steel pipe cutting and positioning device includes a base 1, a workbench 2 fixedly installed at one end of the top of the base 1, a support frame 3 fixedly installed at one end of the bottom of the workbench 2, a motor 4 fixedly installed at one end of the top of the support frame 3, and a cutting blade 5 fixedly installed at one output end of the motor 4. A placement plate 6 is movably installed at one end of the top of the workbench 2, and a fixing block 8 is fixedly installed at one end of the bottom of the placement plate 6. A rotating shaft 9 is rotatably installed inside the fixing block 8, and a first gear 10 is fixedly installed at both ends of the rotating shaft 9. Threads 11 are provided on both sides of the surface of the rotating shaft 9, and sliders 12 are movably installed on both sides of the rotating shaft 9. A positioning block 13 is fixedly installed at one end of the top of the slider 12, and a limiting groove matching the steel pipe is opened on the inner side of the positioning block 13. A first rack 17 matching the first gear 10 is fixedly installed on both sides of the bottom of the workbench 2.

[0030] Specifically, by setting up a clamping and positioning structure, two sets of positioning blocks 13 move in opposite directions to clamp, position and fix the horizontally placed pipe. When subjected to vibration, the positioning blocks 13 can ensure that they provide clamping force for the steel pipe and can be stable enough when subjected to vibration, thereby ensuring that the cut surface of the steel pipe is flat after cutting, which helps to better fit between the finished steel pipe and the welded parts.

[0031] A second rack 18 is fixedly installed on one side of the bottom of the placement plate 6. Support plates 19 are fixedly installed on both sides of the top of the workbench 2. A first rotating rod 20 is movably installed inside the support plate 19. A second gear 21 matching the second rack 18 is movably installed on the outside of the first rotating rod 20. A second rotating rod 23 is movably installed on the inside of the top of the support plate 19. A cover 25 is fixedly installed at one end of the second rotating rod 23. A hinge cover 28 restricting the second rotating rod 23 is fixedly installed at the other end of the second rotating rod 23.

[0032] Specifically, the hinge cover 28 effectively ensures that the second rotating rod 23 will not be affected by the gravity of the cover 25 itself, thus preventing angular displacement. The placement plate 6 provides support and fixation for the second rack 18. At the same time, the placement plate 6 and the second rack 18 provide a power source for the rotation of the second gear 21. The rotation of the cover 25 causes its angle to change, moving it closer to the cutting position, thereby blocking the waste generated during cutting to a certain extent and ensuring a safe working environment.

[0033] Both the first rotating rod 20 and the second rotating rod 23 have a pulley 24 fixedly installed at one end. A belt 22 is fitted onto one end of the pulley 24, and the second rotating rod 23 is connected to the first rotating rod 20 via the belt 22.

[0034] Specifically, by setting the belt 22 and pulley 24, the transmission effect is made more stable, and the baffle 25 can be controlled to ensure that the baffle 25 does not occupy extra space when it is not in operation, which facilitates the placement of steel pipes.

[0035] The baffle 25 is made of chlorinated polyether and has a hollow interior.

[0036] Specifically, the baffle 25 made of chlorinated polyether material can withstand higher temperatures and will not deform even after being exposed to high-temperature waste for a long time. At the same time, the hollow design of the baffle 25 can limit the direction and distance of waste splashing to a greater extent, effectively protecting workers.

[0037] The workbench 2 has a second movable groove 15 symmetrically provided at one end for the slider 12 to move, the placement plate 6 has a first movable groove 14 provided for the slider 12 to move, and the placement plate 6 has a placement groove 7 provided inside.

[0038] Specifically, the second movable groove 15 provides a certain space for the slider 12 to move inside the worktable 2, while restricting it to ensure that it can move along a predetermined route during the movement. The opening of the first movable groove 14 provides space for the slider 12 to move inside the placement plate 6, ensuring that the slider 12 has enough position to move when driven by the rotating shaft 9, thereby ensuring that the positioning block 13 can properly restrict the fixed pipe.

[0039] A connecting block 27 is fixedly installed at one end of the placement plate 6, and a handle 26 is fixedly installed at one end of the bottom of the connecting block 27. A cutting groove 16 for the connecting block 27 to move is provided in the middle of the workbench 2.

[0040] Specifically, the cutting groove 16 provides a certain space for the connecting block 27 to move inside the worktable 2, while restricting it to ensure that its movement direction will not deviate.

[0041] The slider 12 has a threaded groove inside that matches the thread 11, and the two sets of threads 11 are oriented in opposite directions.

[0042] Specifically, through the thread 11, the slider 12 can move a certain distance through the thread 11. The opposing threads 11 allow the two sets of positioning blocks 13 to move in opposite directions and move towards the center, thereby achieving the purpose of fixing the pipe.

[0043] Working Principle: When using this invention, the motor 4 drives the cutting blade 5 to rotate. The user places the pipe to be cut into the placement plate 6 through the placement groove 7, causing it to fall between the two sets of positioning blocks 13. The worker pushes the handle 26, and the movement of the handle 26 causes the connecting block 27 to move, thereby moving the overall position of the placement plate 6. During the movement, the first gear 10 at both ends of the rotating shaft 9 contacts the first rack 17. When the rotating shaft 9 moves, the first gear 10 contacts the first rack 17 and rotates, causing the rotating shaft 9 to rotate. Under the action of the thread 11, the rotation causes the slider 12 to move towards the center, thereby causing the positioning blocks 13 to move towards the center. At this time, the two sets of positioning blocks 13 clamp and fix the pipe. Continue pushing the handle 26... The slider 12 has moved to the end of the inner cavity of the first movable groove 14 and no longer moves. At this time, the cutting work begins. At the same time, during the movement of the placement plate 6, the second rack 18 at one end will contact the second gear 21. When the second rack 18 moves, under the action of meshing, it drives the first rotating rod 20 to rotate. Then, through the belt 22 and the pulley 24, it drives the second rotating rod 23. When the second rotating rod 23 rotates, the baffle 25 rotates around the second rotating rod 23, causing the baffle 25 to flip down, which can effectively prevent the waste generated during cutting from flying and provide a certain degree of protection for the workers. After the cutting is completed, the worker pulls the handle 26 to reset it, and the positioning block 13 releases the restriction on the pipe, making it convenient for the worker to pick up the cut pipe.

[0044] Furthermore, this utility model, through the setting of a clamping and positioning structure, allows two sets of positioning blocks to move in opposite directions, clamping, positioning, and fixing the horizontally placed pipe. When subjected to vibration, the positioning blocks ensure sufficient clamping force for the steel pipe, maintaining sufficient stability during vibration. This ensures that the cut surface of the steel pipe is flush after cutting, thus facilitating better fit between the finished steel pipe and the welded parts. The hinge cover 28 effectively prevents the second rotating rod 23 from shifting due to the weight of the baffle 25 itself. The placement plate 6 provides support and fixation for the second rack 18, while the placement plate 6 and the second rack 18 provide the power source for the rotation of the second gear 21. The rotation of the baffle 25 changes its angle, moving it closer to the cutting position, thereby blocking the cutting debris to a certain extent and ensuring a safe working environment. The belt 22 and pulley 24 make the transmission effect more stable and allow control of the baffle 25, ensuring that it does not occupy extra space when not in use, facilitating the placement of the steel pipe. The material is chlorinated polyether. The baffle 25 can withstand higher temperatures and will not deform even after prolonged exposure to high-temperature waste. The hollow design of the baffle 25 further restricts the direction and distance of waste splashing, effectively protecting workers. The second movable groove 15 provides space for the slider 12 to move within the workbench 2, while also restricting its movement to ensure it follows a predetermined path. The first movable groove 14 provides space for the slider 12 to move within the placement plate 6, ensuring sufficient position for movement when driven by the rotating shaft 9. This allows the positioning block 13 to properly restrict the fixed pipe. The cutting groove 16 provides space for the connecting block 27 to move within the workbench 2, while also restricting its movement to prevent deviation. The slider 12 moves a certain distance via the threaded 11. The opposing threads 11 allow the two sets of positioning blocks 13 to move in opposite directions, converging towards the center to achieve the purpose of fixing the pipe.

[0045] It should be noted that the functions to be achieved by each hardware component in this utility model are supported by a large number of mature technologies and belong to the prior art. The essence of this utility model lies in optimizing and combining existing hardware and its connection methods for specific application scenarios to meet the adaptation requirements of specific application scenarios and solve the problems raised in the background technology without involving improvements to the internal software of the hardware.

[0046] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
