Description

Technical Field

[0001] This utility model relates to the field of pipe processing equipment technology, specifically to a pipe cutting device. Background Technology

[0002] In industrial production and construction, pipe cutting is an indispensable processing step. Currently, most pipe cutting equipment on the market is equipped with fixed limiting devices to hold the pipe in place and complete the cutting operation. However, this traditional fixing method has significant limitations. When processing pipes of different diameters, special clamps must be changed to fit the specific pipe specifications. This process is not only cumbersome but also significantly reduces production efficiency and increases labor and time costs. Furthermore, existing pipe cutting equipment lacks flexibility and adaptability when facing diverse processing needs, especially in scenarios requiring frequent changes in pipe specifications, greatly limiting the equipment's versatility and practicality. Summary of the Invention

[0003] The technical problem to be solved by this utility model is how to enable the pipe cutting device to adapt to various specifications of pipes when cutting pipes.

[0004] The technical solution adopted by this utility model is as follows: a pipe cutting device, including a worktable, the top surface of the worktable is provided with a first sliding groove and a cutting through hole, the cutting through hole is located in the center of the top surface of the worktable, one end of the first sliding groove is provided with a first motor mounting compartment, a first motor is installed in the first motor mounting compartment, a first lead screw is connected in the first sliding groove, the first lead screw and the first motor are connected by a first gear set, an mounting plate is slidably connected to the first sliding groove, a first slider is provided on the bottom surface of the mounting plate, the first slider is connected to the first lead screw, a first arc plate is connected in the middle of the mounting plate, and "L"-shaped sliding parts for fixing the pipe are provided on both sides of the first arc plate.

[0005] The above structure has the following beneficial effects:

[0006] (1) The cutting through hole is located in the center of the top surface of the workbench, which facilitates pipe cutting operations, ensures that chips can be discharged smoothly, avoids clogging the workbench surface, thereby improving work efficiency and keeping the device clean.

[0007] (2) The first slide groove provides a stable sliding guide for the mounting plate, while the first lead screw achieves precise linear motion under the drive of the first motor. The power of the first motor is efficiently transmitted to the first lead screw through the first gear set, which not only improves the stability and efficiency of power transmission, but also effectively reduces energy loss, thereby extending the service life of the device. In addition, the first slider at the bottom of the mounting plate and the first lead screw form a lead screw pair structure. This connection method not only ensures the smooth movement of the mounting plate, but also significantly improves the positioning accuracy, allowing the mounting plate to be flexibly adjusted on the worktable according to the pipe size to meet different cutting needs.

[0008] (3) The first arc plate is fixed in the middle of the mounting plate. Its shape fits the outer wall of the pipe, providing initial support for the pipe, enhancing the stability of the device, and laying the foundation for subsequent fixing operations. The "L"-shaped sliding parts on both sides of the first arc plate are used to fix the pipe. By sliding and adjusting the position, it can adapt to pipes of different diameters, improving the versatility and flexibility of the device.

[0009] Preferably, the mounting plate is provided with a second sliding groove, which is symmetrically arranged on both sides of the first arc-shaped plate, and the second sliding groove is slidably connected to the "L"-shaped sliding member.

[0010] By symmetrically setting second sliding grooves on both sides of the first arc-shaped plate, a stable sliding guide is provided for the "L"-shaped sliding component, which facilitates the adjustment of the fixed position according to the pipe diameter, improves the adaptability of the device, and enables it to adapt to pipes of different specifications.

[0011] Preferably, the bottom of the "L"-shaped slider is provided with a second slider, which is slidably connected to the second groove.

[0012] The cooperation between the second slider and the second groove ensures that the "L"-shaped slider does not deviate in direction during the sliding process, improving the accuracy and stability of the fixing operation. Furthermore, the sliding connection between the two effectively reduces friction, making the "L"-shaped slider smoother during the adjustment process.

[0013] Preferably, the bottom sides of the "L"-shaped sliding member are provided with locking plates, and locking bolts are threadedly connected to the locking plates.

[0014] The locking plate can fix the "L"-shaped sliding component in any position. After the "L"-shaped sliding component is adjusted to the appropriate position, it can be locked by the locking bolt connected to the locking plate thread, which prevents the sliding component from loosening or shifting due to vibration during pipe cutting, thus improving the safety and reliability of the device and ensuring the stability of the cutting process.

[0015] Preferably, the end of the "L"-shaped slider away from the mounting plate is connected to an adjusting plate. The adjusting plate has a circular through hole, and an adjusting rod is slidably connected inside the circular through hole. One end of the adjusting rod has an external thread, and the other end is connected to a second arc-shaped plate.

[0016] The design of the adjusting plate provides a base for the installation of the adjusting rod, which facilitates the fixing of the pipe. The sliding connection between the circular through hole and the adjusting rod allows the adjusting rod to flexibly adjust its extension length to accommodate pipes of different diameters. The design of the second arc plate fits the outer wall of the pipe, providing a stable clamping force.

[0017] Preferably, the adjusting rod is threaded with a locking knob.

[0018] The locking knob design enables quick adjustment of the extension length of the adjusting rod. When cutting pipes of different specifications, the position of the adjusting rod can be changed by adjusting the position of the locking knob, so that the second arc plate connected to the adjusting rod can quickly abut against the pipe, making the operation convenient and quick.

[0019] Preferably, a baffle is provided at the end of the adjusting rod away from the locking knob, and an elastic element is installed on the adjusting rod, with the two ends of the elastic element abutting against the top surface of the baffle and the bottom surface of the adjusting rod, respectively.

[0020] The use of elastic elements can absorb the vibration and shaking generated by the pipe during the cutting process. Even if the pipe deviates slightly, the elastic elements can ensure that the second arc plate always fits tightly against the outer wall of the pipe, which improves the cutting accuracy and ensures the stability of the cutting effect.

[0021] Preferably, the worktable is provided with a cutting blade fixing rod, the cutting blade fixing rod is provided with a groove, a second motor and a second lead screw are installed in the groove, one end of the second lead screw is connected to the output end of the second motor, and the other end is connected to the cutting blade fixing rod.

[0022] By installing a second motor and a second lead screw inside the groove, space can be effectively saved. The second motor drives the cutting blade moving frame through the lead screw, realizing the longitudinal adjustment of the cutting blade and improving cutting efficiency and accuracy.

[0023] Preferably, a cutting blade moving component is slidably connected within the groove. One end of the cutting blade moving component is provided with a third slider, which is connected to the second lead screw. The end of the cutting blade moving component away from the second lead screw is provided with a cutting blade mounting compartment and a third motor mounting compartment. A cutting blade is rotatably connected within the cutting blade mounting compartment. A third motor and a third lead screw are installed within the third motor mounting compartment. One end of the third lead screw is connected to the output end of the third motor, and the other end is connected to the rotating shaft of the cutting blade via a second gear set.

[0024] The cooperation between the third slider and the second lead screw ensures the smooth movement of the cutting blade. When the third motor rotates, it will drive the second lead screw to rotate, which in turn causes the third slider connected to the second lead screw to move, and at the same time drives the cutting blade to move. This effectively reduces vibration and error during operation. Furthermore, setting the cutting blade and motor in different mounting compartments facilitates the maintenance and replacement of components and prevents cutting chips from splashing onto the third motor and the second lead screw during pipe cutting.

[0025] Preferably, a water tank is provided on one side of the cutting blade fixing rod, and a telescopic pipe is connected to the top of the water tank.

[0026] By channeling coolant from the water tank to the cutting blade and pipe through a telescopic tube, the high temperatures generated during cutting can be effectively reduced, extending the lifespan of the cutting blade. Furthermore, the use of coolant can reduce chip splashing, improve the working environment, and enhance cutting quality, making it particularly suitable for cutting metal pipes.

[0034] Example

[0035] The following description, in conjunction with specific embodiments, provides further details. Figure 1-3As shown, this embodiment is a pipe cutting device, including a worktable 1, a first motor 103, a first lead screw 104, and a first gear set 105. A first sliding groove 101 and a cutting through hole 107 are provided on the top surface of the worktable 1. The cutting through hole 107 is located in the center of the top surface of the worktable 1 and is used to realize the pipe cutting operation; the first sliding groove 101 is symmetrically arranged on both sides of the cutting through hole 107 to provide guidance for the moving parts of the device. A first motor mounting compartment 102 is provided at one end of the first slide groove 101, and the first motor 103 is installed in this compartment. The first lead screw 104 is arranged in the first slide groove 101 by a rotatable connection, and a first gear set 105 is assembled at the end near the first motor 103, through which the power of the first motor 103 is transmitted to the first lead screw 104. A mounting plate 2 is slidably connected to the first slide groove 101, and a first slider 201 is provided on the bottom surface of the mounting plate 2. The first slider 201 has a threaded hole, so that the first slider 201 and the first lead screw 104 are connected by a lead screw pair. The connection is as follows: A first arc-shaped plate 203 is fixed to the center of the mounting plate 2 by bolts. Second sliding grooves 202 are symmetrically arranged on both sides of the first arc-shaped plate 203. An "L"-shaped sliding member 3 is slidably connected to the second sliding grooves 202. To prevent the "L"-shaped sliding member 3 from deviating during sliding, a second slider 301 is provided at the bottom of the "L"-shaped sliding member 3, allowing the second slider 301 to slidably connect to the second sliding groove 202. Furthermore, locking plates 302 are provided on both sides of the bottom of the "L"-shaped sliding plate, with locking bolts threaded onto the locking plates 302. When the "L"-shaped sliding member 3 slides to the engagement position... After positioning, the "L"-shaped sliding member 3 can be locked by rotating the locking bolt. An adjusting plate 4 is welded to the end of the "L"-shaped sliding member 3 furthest from the mounting plate 2. The adjusting plate 4 has a circular through hole, through which an adjusting rod 501 is slidably connected. This adjusting rod 501 is part of the adjusting member 5. One end of the adjusting rod 501 has an external thread, and a locking knob 6 is threadedly connected to it. By adjusting the position of the locking knob 6, the extension length of the adjusting rod 501 towards the pipe can be determined. The other end of the adjusting rod 501 is welded to a second arc-shaped plate 503. 503 is used to fix the pipe, and a silicone pad is provided on the side of the second arc plate 503 facing the pipe to avoid damage to the pipe surface and improve the fixing effect. In addition, a baffle 502 is provided at the end of the adjusting rod 501 away from the locking knob 6. The two ends of the elastic element 7 installed on the adjusting rod 501 abut against the top surface of the baffle 502 and the bottom surface of the adjusting plate 4, respectively. This design can effectively prevent the pipe from shaking during the cutting process, resulting in an unsatisfactory cutting effect, and ensure that even if the pipe position is slightly offset, the second arc plate 503 can still fit tightly against the outer wall of the pipe, thereby ensuring the stability and accuracy of the cutting.

The third lead screw 904 is connected to the rotating shaft of the cutting blade 10. A second gear set 905 is provided between the third lead screw 904 and the rotating shaft of the cutting blade 10. The second gear set 905 is a bevel gear set. The power transmitted from the third motor 903 through the third lead screw 904 is transmitted to the rotating shaft of the cutting blade 10 through the second gear set 905, thereby driving the cutting blade 10 to rotate and achieving precise cutting of the pipe.

[0037] In addition, a water tank 11 is provided on one side of the cutting blade fixing rod 8. A telescopic pipe 12 is connected to the top of the water tank 11. The water tank 11 and the telescopic pipe 12 can cool down the pipe and the cutting blade 10 when the pipe cutting device cuts the metal pipe. A slide rail 106 is also provided at the bottom of the workbench 1. A scrap box 13 is slidably connected to the slide rail 106.

[0038] Working principle:

[0039] When the pipe needs to be cut, the position of the mounting plate 2 is first adjusted by the first motor 103. Then, the "L" sliding member that is slidably connected to the mounting plate 2 is pushed to both ends of the mounting plate 2. Then, the pipe is placed on the first arc plate 203. Then, the position of the "L" sliding member 3 is adjusted so that the adjusting member 5 installed on the "L" sliding member 3 is located on the left and right sides above the pipe. At this time, the length of the adjusting rod 501 that needs to be extended is determined by adjusting the locking bolt on the adjusting rod 501 so that the second arc plate 503 connected to the adjusting rod 501 fits against the outer wall of the pipe.

[0040] After completing the above-described pipe fixing operation, the second motor 802 is started, driving the second lead screw 803 to rotate. This causes the cutting blade moving part 9 to move along the second lead screw 803, aligning the cutting blade with the cutting point of the pipe. Then, the third motor 903 is started, driving the cutting blade 10 to rotate at high speed through the third lead screw 904 and the second gear set 905. Simultaneously, the position of the cutting blade moving part 9 continues to move, allowing the cutting blade 10 to gradually cut into the pipe, completing the pipe cutting operation. After cutting, the above steps are reversed to reset the cutting blade 10, release the pipe, and remove the cut pipe.
