Description

Technical Field

[0001] This utility model relates to the field of pipeline processing technology, and in particular to a pipeline feeding device. Background Technology

[0002] Currently, pipelines refer to pipes used to transport fluids (liquids, gases) or sometimes solid slurries (such as coal slurry). Pipelines are often used in conjunction with other devices to form a complete set of equipment. Pipelines are typically cut to different lengths as needed to accommodate different conveying devices. The specific process involves pushing the pipeline, stopping when one end touches a limit switch, and then a cutting machine cuts the pipeline. The limit switch is used to determine the length of the cut pipeline and to start and stop the cutting machine. However, a current problem is that because the cut end of the pipeline often has burrs or flash, the determination of the cut pipeline length is based on the limit switch. Therefore, when determining the required cut length, burrs or flash may be included in the pipeline length calculation, leading to errors in the cut pipeline length.

[0003] For example, Chinese utility model patent application number CN202421878136.8, filed on August 5, 2024, describes a steel pipe cutting device, including a worktable; an intermittent moving mechanism horizontally mounted on the worktable, with a rotating mechanism connected to the drive end of the intermittent moving mechanism, and a clamping mechanism mounted on the rotating mechanism, the clamping end of which clamps a steel pipe; and a guiding mechanism mounted on the worktable along the direction perpendicular to the intermittent moving mechanism, with a cutting mechanism connected to the drive end of the guiding mechanism, which drives the cutting end of the cutting mechanism to abut against the outer circumferential wall of the steel pipe. This solution makes it easy to control the cutting length of the steel pipe, enabling the cutting of a single steel pipe into multiple segments of the same length without manual segmentation, thus increasing efficiency. However, this prior art does not include a device for treating burrs on the cut pipe. Due to the presence of burrs, the burr length is factored into the determination of the pipe length, leading to significant errors in the cut pipe length. Therefore, a pipe cutting device is needed to address this problem. Utility Model Content

[0004] This invention aims to solve the problems existing in the prior art by providing a pipeline cutting device that can automatically grind burrs or flash on the pipeline cutting end before cutting the pipeline, so as to reduce the error caused by burrs or flash when determining the pipeline length.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: This pipeline feeding device includes a base, a positioning base plate for mounting a cutting machine and a support plate for supporting the pipeline, a grinding component corresponding to the end of the pipeline and which can be pushed by the pipeline, a driving component that drives the grinding component to rotate and grind the end of the pipeline when the grinding component is pushed, and a limiting component for adjusting the moving distance of the grinding component.

[0006] To further improve the design, a positioning channel that matches the outer diameter of the pipeline is provided on the positioning base plate.

[0007] Further improvements include the addition of a support channel on the support plate that matches the outer diameter of the pipeline, with the axis of the support channel coinciding with the axis of the positioning channel.

[0008] Further improvements include a grinding component comprising a mounting plate connected to the drive component and a grinding layer fixed to the side of the mounting plate facing the pipeline.

[0009] Further improvements include a mounting plate fixed to the base, a drive cylinder fixed to the mounting plate and extending along the axis, a drive rod slidably connected inside the drive cylinder and fixedly connected to the mounting plate, and a linkage component that drives the drive rod to rotate when the drive rod slides.

[0010] Further improvements include a spiral groove on the outside of the drive rod, a locking block fixed to the inner wall of the drive cylinder and located inside the spiral groove, a return spring installed between the drive cylinder and the mounting plate, and the locking block driving the drive rod to rotate by sliding along the spiral groove when the drive rod slides inside the drive cylinder.

[0011] Further improvements include a limiting plate fixed to the base and a screw threaded onto the limiting plate. The screw can extend into the drive cylinder to limit the sliding distance of the drive rod.

[0012] Further improvements include the addition of chip grooves on the base that correspond to the grinding parts.

[0013] The beneficial effects of this utility model are: This utility model solves the fundamental problem of inaccurate measurement of the actual length of pipelines caused by burrs or flash, making the final determined pipeline length closer to the theoretical value or design requirements, greatly reducing the dimensional error caused by burrs, improving product quality and assembly accuracy, avoiding the need for additional manual or equipment grinding after cutting, significantly shortening the time of the entire material cutting process, and reducing labor costs.

[0016] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0017] See attached document Figures 1-4 In this embodiment, the pipeline feeding device includes a base 1, on which a positioning base plate 2 for mounting a cutting machine and a support plate 3 for supporting the pipeline are mounted. The positioning base plate 2 has a positioning channel 2a that matches the outer diameter of the pipeline, and the support plate 3 has a support channel 3a that matches the outer diameter of the pipeline. The axis of the support channel 3a coincides with the axis of the positioning channel 2a. The pipeline is fed through the support channel 3a and then passes through the positioning channel 2a, completing the feeding process. The cutting machine on the positioning base plate 2 can cut the pipeline through the positioning channel 2a. The pipeline in positioning channel 2a is cut. A grinding component 4 is provided above the base 1. The grinding component 4 corresponds to the end of the pipeline. The pipeline can push the grinding component 4. A driving component 5 that cooperates with the grinding component is provided behind the grinding component 4. The driving component 5 is used to drive the grinding component 4 to rotate when the grinding component 4 is pushed. The grinding component 4 grinds the end of the pipeline by rotating. A limiting component 6 that can adjust the moving distance of the grinding component 4 is provided behind the driving component 5. A chip groove 7 corresponding to the grinding component 4 is provided on the base 1 to receive the chips that fall during grinding.

[0018] See attached document Figures 1-4 The grinding component 4 includes a mounting plate 4-1 and a grinding layer 4-2. The grinding layer 4-2 is located on the side of the mounting plate 4-1 near the pipeline. The grinding layer 4-2 is a grinding wheel. The grinding layer 4-2 grinds away the burrs and flash at the end of the pipeline by rotating. The mounting plate 4-1 is connected to the drive component 5.

[0019] See attached document Figures 1-4The driving component 5 includes a mounting plate 5-1, a driving cylinder 5-2, a driving rod 5-3, and a linkage 5-4. The mounting plate 5-1 is fixed on the base 1 and corresponds to the positioning base plate 2. The driving cylinder 5-2 passes through and is fixed on the mounting plate 5-1. The driving cylinder 5-2 is configured to be axially continuous, and the axis of the driving cylinder 5-2 coincides with the axis of the pipeline. The driving rod 5-3 slides inside the driving cylinder 5-2, and one end of the driving rod 5-3 extends out of the driving cylinder 5-2 and is fixedly connected to the mounting plate 4-1. The linkage 5-4 is disposed on the driving cylinder 5-2 and the driving rod 5-3. The linkage 5-4 is used to drive the driving rod 5-3 to rotate when it slides. Specifically, the linkage 5-4 includes three parts: a spiral groove 5-4-1, a locking block 5-4-2, and a return spring 5-4-3. The spiral groove 5-4-1 is formed in the driving rod 5-2. 3. On the outside, the locking block 5-4-2 is fixed to the inner wall of the drive cylinder 5-2. The locking block 5-4-2 is located inside the spiral groove 5-4-1. The return spring 5-4-3 is installed between the end of the drive cylinder 5-2 and the mounting plate 4-1 and surrounds the outside of the drive rod 5-3. The return spring 5-4-3 is used to push the mounting plate 4-1 to press against the end of the pipeline. Since the mounting plate 4-1 will be in a rotating state, the two ends of the return spring 5-4-3 are not fixedly connected to the mounting plate 4-1 and the drive cylinder 5-2. When the drive rod 5-3 slides inside the drive cylinder 5-2, the locking block 5-4-2 drives the drive rod 5-3 to rotate by sliding along the spiral groove 5-4-1. The rotation of the drive rod 5-3 drives the mounting plate 4-1 to rotate. The rotation of the mounting plate 4-1 drives the grinding layer 4-2 to rotate. The rotation of the grinding layer 4-2 grinds the burrs and flash at the end of the pipeline.

[0020] See attached document Figures 1-4 The limiting component 6 includes a limiting plate 6-1 and a screw 6-2. The limiting plate 6-1 is fixed on the base 1 and located behind the mounting plate 5-1. The screw 6-2 is threaded onto the limiting plate 6-1. The axis of the screw 6-2 coincides with the axis of the drive rod 5-3. The screw 6-2 can enter the drive cylinder 5-2 from the rear end. The position of the screw 6-2 within the drive cylinder 5-2 can be adjusted by rotation to limit the maximum sliding distance of the drive rod 5-3.

[0021] In use, the cutting machine is installed on the positioning base plate 2. The pipeline is then passed through the support channel 3a and the positioning channel 2a, and presses against the grinding layer 4-2 on the mounting plate 4-1. The pipeline pushes the mounting plate 4-1 to move by feeding. The mounting plate 4-1 drives the drive rod 5-3 to slide inside the drive cylinder 5-2. When the drive cylinder 5-2 slides, it drives the mounting plate 4-1 to rotate through the spiral groove 5-4-1 and the locking block 5-4-2. The rotation of the mounting plate 4-1 drives the grinding layer 4-2 to rotate. The grinding layer 4-2 grinds the burrs and flash at the end of the pipeline, making the end of the pipeline flat. The debris generated by grinding falls into the debris groove 7. When the drive rod 5-3 presses against the screw 6-2, the drive rod 5-3 stops sliding, the grinding layer 4-2 stops rotating, the pipeline feed stops, and then the cutting machine cuts the pipeline. By rotating the screw 6-2, the position of the screw 6-2 inside the drive cylinder 5-2 can be adjusted to adjust the length of the pipeline to be cut.

Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model.
