Abstract
Description
Technical Field
[0001] This application relates to the field of cutting equipment, and more specifically, to a pipe cutting device. Background Technology
[0002] Pipes (such as metal pipes, plastic pipes, or composite material pipes) are widely used in processing and manufacturing, construction and installation, and the production of home appliances and automotive parts. In actual production processes, pipes typically need to be cut to specified lengths to meet the requirements of subsequent assembly or welding processes. Therefore, achieving rapid, stable, and safe cutting of pipes is an important issue in the field of related equipment.
[0003] Existing pipe cutting methods mainly include manual hand-held cutting with tools (such as angle grinders and handheld chainsaws) and cutting using a simple cutting table with a cutting blade. While these methods are relatively simple in structure, they still have the following shortcomings in practice:
[0004] Insufficient positioning and clamping adaptability
[0005] Some cutting tables only have fixed-size V-grooves or simple stops to support the pipe body, making it difficult to adapt to pipes with different outer diameters. When the pipe specifications change, it is often necessary to replace the clamps or readjust the tooling, resulting in poor versatility. Furthermore, when the clamping force is insufficient, the pipe body is prone to slipping or rotating during the cutting feed, leading to skewing of the cut, increased dimensional errors, and affecting the cutting quality and consistency.
[0006] The cutting blade is prone to interference with the work surface, causing damage.
[0007] In structures using pressure-type or oscillating cutting blades, if the blade stroke lacks sufficient clearance after the cutting action is completed, it is prone to collision or friction with the cutting table or support structure, which can cause blade wear, chipping, or even blade jamming, shortening the blade life and increasing maintenance costs.
[0008] Material discharge relies on manual labor, which limits safety and efficiency.
[0009] After cutting, existing equipment often requires operators to manually remove the cut pipe sections from the cutting area for collection or transport. Because of the presence of moving parts such as rotating blades and clamping mechanisms near the cutting area, manual removal poses safety risks such as cuts and pinches. Furthermore, manual handling increases the cycle time for each cutting operation, reduces continuous work efficiency, and is detrimental to automated production. Summary of the Invention
[0010] The summary section of this application is intended to provide a brief overview of the concepts, which will be described in detail in the detailed description section below. This summary section is not intended to identify key or essential features of the claimed technical solutions, nor is it intended to limit the scope of the claimed technical solutions.
[0011] To address the technical problems mentioned in the background section above, some embodiments of this application provide a pipe cutting device, including: a cutting table, a cutting blade, and a driving component; the cutting table has a limiting groove for accommodating the pipe to be cut and a clearance groove for inserting the cutting blade into; the driving component is used to drive the cutting path to move closer to and away from the pipe to be cut; a discharge hopper is provided on the cutting table; the discharge hopper is connected to the limiting groove and extends downward at an angle.
[0012] Furthermore, the cutting table includes: a support plate, a first clamping plate, and a second clamping plate; the first clamping plate and the second clamping plate are both located above the support plate; the first clamping plate, the second clamping plate, and the support plate form the limiting groove; the driving member is also used to drive the first clamping plate and the second clamping plate to move closer to or further away from each other above the support plate.
[0013] Furthermore, multiple slots are formed on both the first clamping plate and the second clamping plate.
[0014] Furthermore, a conveyor is provided on the support platform, which is used to transport the tube to be cut on the conveyor toward the discharge hopper.
[0015] Furthermore, the conveyor includes a drive motor and a spiral tube; the length direction of the spiral tube coincides with the axis of the tube to be cut; the drive motor is mounted on the support platform, and the output end of the drive motor is connected to the spiral tube; two sets of spiral tubes and two sets of drive motors are provided, and the tube to be cut is located between the two sets of spiral tubes; a spiral protrusion and a slot are formed on the spiral tube; the slot is used for the cutting blade to be inserted when cutting the tube, and the spiral protrusion is used to contact the outer wall of the tube to be cut.
[0016] Furthermore, a rubber pad is provided on the spiral protrusion, and the rubber pad is perfectly matched with the spiral protrusion.
[0017] Furthermore, a first clamping surface and a second clamping surface are formed on both the first clamping plate and the second clamping plate; both the first clamping surface and the second clamping surface are inclined to the support platform; wherein, the first clamping surface is close to the support platform, and the second clamping surface is in contact with the first clamping surface; the first clamping surface is inclined away from the tube to be cut, and the second clamping surface is inclined close to the tube to be cut.
[0018] Furthermore, both the first and second clamping surfaces are curved surfaces.
[0019] The beneficial effects of this application are as follows:
[0020] The limiting groove is formed by the bearing plate, the first clamping plate and the second clamping plate. The driving component drives the first clamping plate and the second clamping plate to move closer or further apart, so as to achieve adaptive clamping and positioning for pipes with different outer diameters. Compared with the fixed limiting structure, it has stronger versatility. At the same time, the clamping is more reliable, which can reduce the cut deviation and dimensional error caused by pipe slippage and rotation during the cutting process, and improve the consistency and quality of cutting.
[0021] The cutting table is equipped with a clearance groove. When the cutting blade completes the cut and continues to move downward, it can insert into the clearance groove to obtain clearance space, thereby reducing the possibility of collision or friction between the cutting blade and the cutting table, reducing the risk of chipping, wear, and jamming, improving equipment reliability and extending the service life of the cutting tool.
[0022] The cutting table is equipped with a downward-sloping discharge hopper connected to the limiting groove. The cut pipe section can automatically fall into the discharge hopper and be discharged under the action of gravity, reducing the frequency of operators manually picking up parts near the blade and reducing safety hazards such as cuts and pinches. At the same time, it shortens the material picking and unloading time, which is conducive to continuous cutting and cycle-based production, improving overall efficiency and automation level.

[0038] Reference Figures 1-5 ,
[0039] A pipe cutting device includes a cutting table 1, a cutting blade 2, and a driving component 3. The cutting table 1 has a limiting groove 14 for accommodating the pipe to be cut and a recess for the cutting blade 2 to insert into. The driving component 3 moves the cutting path closer to and away from the pipe to be cut. A discharge hopper 4 is provided on the cutting table 1; the discharge hopper 4 communicates with the limiting groove 14 and extends downwards at an angle. The driving component 3 moves the cutting blade 2 downwards, cutting the pipe. When the cutting blade 2 completely cuts the pipe, it partially lies below the pipe, thus embedding itself in the recess and preventing damage from contact with the cutting table 1. After cutting the pipe, the cut pipe falls into the discharge hopper 4 and is discharged outwards. Therefore, it can automatically cut the pipe and automatically output the cut pipe, thus avoiding the danger of manually handling the cut pipe. This greatly improves the automation level of pipe cutting and better protects the safety of workers. The cutting blade 2 is an electric saw that cuts the pipe through a rotating disc.
[0040] Specifically, the cutting table 1 includes: a support plate 11, a first clamping plate 12, and a second clamping plate 13; both the first clamping plate 12 and the second clamping plate 13 are located above the support plate 11; the first clamping plate 12, the second clamping plate 13, and the support plate 11 form the limiting groove 14; the driving member 3 is also used to drive the first clamping plate 12 and the second clamping plate 13 to move closer to or further away from each other above the support plate 11. The first clamping plate 12 and the second clamping plate 13 clamp the tube to be cut by moving closer to each other, which can clamp tubes of different sizes and has a wider range of applications. The driving member 3 includes a first cylinder 31 and a second cylinder 32. The first cylinder 31 is connected to the first clamping plate 12, and the second cylinder 32 is connected to the second clamping plate 13, so that the first cylinder 31 and the second cylinder 32 drive the first clamping plate 12 and the second clamping plate 13 to move closer to or further away from each other. The driving member 3 also includes a third cylinder 33, which is used to drive the cutting blade 2 to move. A mounting bracket is provided on the cutting table 1. The mounting bracket is used to install the third cylinder 33. The output end of the third cylinder 33 is connected to the cutting blade 2, thereby driving the cutting blade 2 to move up and down.
[0041] Specifically, multiple slots are formed on both the first clamping plate 12 and the second clamping plate 13. The slots are designed to increase the friction between the first clamping plate 12 and the second clamping plate 13 after clamping the tube to be cut, thus preventing the tube from slipping.
[0042] Specifically, a conveyor is installed on the support platform to transport the pipe body to be cut on the conveyor toward the discharge hopper 4. The purpose of the conveyor is to more automatically transport the cut pipe body to the discharge hopper 4 and to transport the pipe body that needs to be cut further to below the cutting blade 2, resulting in a higher degree of automation and simpler operation.
[0043] Specifically, the conveyor includes a drive motor and a spiral tube 5; the length direction of the spiral tube 5 coincides with the axis of the tube to be cut; the drive motor is mounted on the support platform, and the output end of the drive motor is connected to the spiral tube 5; two sets of spiral tubes 5 and drive motors are provided, and the tube to be cut is located between the two sets of spiral tubes 5; a spiral protrusion 51 and a slot 52 are formed on the spiral tube 5; the slot 52 is used for the cutting blade 2 to be inserted when cutting the tube to be cut, and the spiral protrusion 51 is used to contact the outer wall of the tube to be cut.
[0044] The spiral tube 5 is rotated by a drive motor, which in turn moves the tube to be cut in contact with it. This design saves space, simplifies installation, and facilitates the transport of the tube to be cut. The slot 52 is designed to prevent the cutting blade 2 from being damaged by contact with the spiral tube 5. The spiral tube 5 also provides support for the tube to be cut, positioned between two spiral tubes 5, thus achieving both support and transport of the tube.
[0045] Specifically, a rubber pad is provided on the spiral protrusion 51, and the rubber pad is perfectly matched with the spiral protrusion 51. The rubber pad is used to increase the friction between the spiral tube 5 and the tube body to be cut, so that it can be transported better.
[0046] In some embodiments, a first clamping surface and a second clamping surface are formed on both the first clamping plate 12 and the second clamping plate 13; both the first clamping surface and the second clamping surface are inclined to the support platform; wherein, the first clamping surface is close to the support platform, and the second clamping surface is in contact with the first clamping surface; the first clamping surface is inclined away from the tube to be cut, and the second clamping surface is inclined close to the tube to be cut. Both the first clamping surface and the second clamping surface are curved surfaces. By using the first clamping surface and the second clamping surface, the tube to be cut can be clamped in both left and right directions, and can also be limited in both up and down directions, thereby completely preventing the tube to be cut from shaking during cutting, avoiding errors caused by shaking, and better ensuring the cutting quality.
[0047] In other embodiments, both the first clamping plate 12 and the second clamping plate 13 are arc-shaped plates, with the curvature of the plates similar to that of the pipe to be cut. A rotating roller 6 is mounted on the first clamping plate 12, rotatably connected to it. When the first clamping plate 12 presses down on the pipe to be cut, the first clamping plate 12 presses against the pipe through the rotating roller 6. This allows the first clamping plate 12 and the second clamping plate 13 to press the cut pipe onto the threaded pipe. At this point, there is significant pressure between the threaded pipe and the cut pipe, making it easier to transport the cut pipe by rotating the threaded pipe. The first clamping plate 12 and the second clamping plate 13 can also press the pipe to be cut before cutting, facilitating transport and allowing for precise control of the transport distance. This avoids slippage due to insufficient friction.
[0048] In addition, an elastic bag 7 is provided on the first clamping plate 12. The elastic bag 7 is fixed on the first clamping plate 12. Preferably, the first clamping plate 12 is provided with an installation groove, and the elastic bag 7 is placed in the installation groove. The elastic bag 7 is externally connected to a water injection pipe 8 and a water injection pump 9. The water injection pump 9 is externally connected to a water source. The water injection pump 9 injects water into the elastic bag 7, causing the elastic bag 7 to expand and press against the pipe body to be cut, thereby also playing a role in fixing the pipe body to be cut.
