Description

Technical Field

[0001] This utility model relates to the field of pipe processing equipment technology, and in particular to a beveling pipe cutting machine. Background Technology

[0002] During the operation of a beveling pipe cutter, the front and rear chucks need to move along guide rails to clamp the pipe.

Detailed Implementation

[0015] To more clearly illustrate the technical solutions in the embodiments of this utility model, the drawings used in the description of the embodiments have been briefly explained above. Obviously, the described drawings are only a part of the embodiments of this utility model, and not all of them. Those skilled in the art can obtain other design schemes and drawings based on these drawings without creative effort.

[0016] The following will clearly and completely describe the concept, specific structure, and technical effects of this utility model in conjunction with embodiments and accompanying drawings, so as to fully understand the purpose, features, and effects of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are all within the scope of protection of this utility model. Furthermore, all connections / linkages mentioned herein do not simply refer to direct contact between components, but rather to the ability to form a better connection structure by adding or reducing connecting accessories according to specific implementation conditions. The various technical features in this utility model can be combined interactively without contradicting each other.

[0017] During the operation of a beveling pipe cutter, the front and rear chucks need to move along the guide rails to clamp the pipe. However, during the movement of the chucks, human error or abnormal control program can easily cause the two chucks to get too close together and collide. This can not only damage the chucks themselves but also affect the normal operation of the entire beveling pipe cutter, reducing the equipment's lifespan and processing accuracy.

[0018] Therefore, this utility model proposes a beveling pipe cutting machine, referring to... Figures 1-5It includes a frame 100, a first guide rail 110, a front chuck assembly 200, a rear chuck assembly 300, a cutting assembly 400, a first anti-collision unit 510, and a second anti-collision unit 520. The first guide rail 110 is disposed on the top of the frame 100 and extends along the length of the frame 100. The front chuck assembly 200 is slidably connected to the first guide rail 110 and can be translated along the first guide rail 110 for clamping one end of the pipe. The rear chuck assembly 300 is slidably connected to the first guide rail 110 and can be translated along the first guide rail 110 for clamping one end of the pipe. The guide rail 110 is slidably connected and can be translated along the first guide rail 110. The rear chuck assembly 300 is disposed opposite to the front chuck assembly 200 and is used to clamp the other end of the pipe. The cutting assembly 400 is disposed on the frame 100 and is used to cut the pipe. The first anti-collision unit 510 includes a first limiting groove 511, a first limiting switch 512, a first telescopic rod 513 and a first sensing block 514. The first limiting switch 512 and the first telescopic rod 513 are disposed on the frame. On frame 100, the first limit switch 512 is electrically connected to the first telescopic rod 513. The first sensing block 514 is disposed on the rear chuck assembly 300 near the front chuck assembly 200 and is used to abut against the first limit switch 512. The first limiting groove 511 is disposed on the rear chuck assembly 300 and is used for the insertion of the first telescopic rod 513. The second anti-collision unit 520 includes a second limiting groove 521, a second limit switch 522, a second telescopic rod 523, and a second sensing block 524. The second limit switch 522 and the second telescopic rod 523 are disposed on frame 100. The second limit switch 522 is electrically connected to the second telescopic rod 523. The second sensing block 524 is disposed on the front chuck assembly 200 near the rear chuck assembly 300 and is used to abut against the second limit switch 522. The second limiting groove 521 is disposed on the front chuck assembly 200 and is used for the insertion of the second telescopic rod 523.

[0019] The frame 100 provides basic support; the first guide rail 110 provides guidance for the translation of the front chuck assembly 200 and the rear chuck assembly 300; the front chuck assembly 200 cooperates with the rear chuck assembly 300 to keep the pipe stable, transport the pipe and ensure that the pipe is fixed in position during cutting; the cutting assembly 400 performs the task of cutting the pipe, processing the pipe into bevels and other shapes according to the set requirements; the first limit switch 512 is electrically connected to the first telescopic rod 513. When it abuts against the first sensing block 514 on the rear chuck assembly 300, the first telescopic rod 513 is inserted into the first limit groove 511, restricting the movement of the rear chuck assembly 300 by mechanical blocking; the second limit switch 522 is electrically connected to the second telescopic rod 523. When it abuts against the second sensing block 524 on the front chuck assembly 200, the second telescopic rod 523 is inserted into the second limit groove 521, restricting the movement of the front chuck assembly 200 by mechanical blocking. By setting up the first anti-collision unit 510 and the second anti-collision unit 520, after the chuck assembly moves into position, the telescopic rod is driven to insert into the limit slot by the cooperation of the sensing block and the limit switch, which restricts the chuck assembly from continuing to move and prevents the chuck assembly from colliding due to excessive proximity. This protects the equipment, avoids damage to parts caused by collisions, ensures that the pipe cutting machine can operate stably and normally, improves the safety and reliability of equipment operation, extends the service life of the equipment, and helps to ensure the accuracy and quality of pipe processing.

[0020] When the beveling pipe cutter is working, the rear chuck assembly 300 feeds the pipe to the cutting assembly 400 along the first guide rail 110, and the front chuck assembly 200 clamps the pipe during cutting. When the rear chuck assembly 300 moves along the first guide rail 110 toward the front chuck assembly 200 until the first sensing block 514 abuts against the first limit switch 512, the first limit switch 512 receives a sensing signal and triggers the first telescopic rod 513 to insert into the first limit groove 511, thereby restricting the rear chuck assembly 300 from moving closer to the front chuck assembly 200. Similarly, when the front chuck assembly 200 moves toward the rear chuck assembly 300, causing the second sensing block 524 to abut against the second limit switch 522, the second limit switch 522 triggers the second telescopic rod 523 to insert into the second limit groove 521, restricting the front chuck assembly 200 from moving closer to the rear chuck assembly 300. When the chuck assembly needs to move in the reverse direction, such as when the pipe is released after processing, the sensing block separates from the limit switch as the chuck assembly moves in the reverse direction, and the corresponding telescopic rod leaves the limit groove, allowing the chuck assembly to move normally. Specifically, the laser cutting assembly 400 includes a Y-axis slide slidably mounted on the frame 100, a Y-axis drive mechanism for driving the Y-axis slide to move along the Y-axis direction, a Z-axis slide slidably mounted on the Y-axis slide, a Z-axis drive mechanism for driving the Z-axis slide to move along the Z-axis direction, and a laser cutting head mounted at the lower end of the Z-axis slide. A B-axis swing mechanism is provided between the Z-axis slide and the laser cutting head, and the angle range of the B-axis swing mechanism driving the laser cutting head to deflect is ±45°. The specific structure and working principle of the front chuck assembly 200 and the rear chuck assembly 300 are existing technologies and will not be described in detail here.

[0021] During the use of the beveling pipe cutting machine, the front chuck assembly 200 and the rear chuck assembly 300 may move excessively away from and disengage from the guide rail due to misoperation, control program malfunction, or other reasons. Therefore, in one embodiment, a first limiting unit 530 and a second limiting unit 540 are also included. The first limiting unit 530 includes a third limiting groove 531, a third limiting switch 532, a third telescopic rod 533, and a third sensing block 534. The third limiting switch 532 and the third telescopic rod 533 are mounted on the frame 100. The third limiting switch 532 is electrically connected to the third telescopic rod 533. The third sensing block 534 is located on the rear chuck assembly 300 at one end away from the front chuck assembly 200 and is used to abut against the third limiting switch 532. The third limiting groove 531 is located on the rear chuck assembly 300. The first limiting unit 530 is used for inserting the third telescopic rod 533. The second limiting unit 540 includes a fourth limiting groove 541, a fourth limiting switch 542, a fourth telescopic rod 543, and a fourth sensing block 544. The fourth limiting switch 542 and the fourth telescopic rod 543 are mounted on the frame 100. The fourth limiting switch 542 is electrically connected to the fourth telescopic rod 543. The fourth sensing block 544 is mounted on the front chuck assembly 200 at one end away from the rear chuck assembly 300 and is used to abut against the fourth limiting switch 542. The fourth limiting groove 541 is mounted on the front chuck assembly 200 and is used for inserting the fourth telescopic rod 543. By setting the first limiting unit 530 and the second limiting unit 540, and by using the cooperation of the sensing block and the limiting switch to drive the telescopic rod into the limiting groove, it is possible to effectively prevent the front and rear chuck assemblies 300 from falling off the guide rail due to excessive distance. This further ensures the stability and safety of equipment operation, ensuring that the chuck assembly is always in the normal working position throughout the entire pipe processing process, maintaining reliable clamping of the pipe. This helps improve the accuracy and quality of pipe cutting, reduces equipment failures caused by abnormal chuck assembly position, lowers maintenance costs, and increases the overall service life of the equipment and the efficiency of production and processing.

[0022] During the cutting operation of the beveling pipe cutter, a large number of sparks generated during cutting may fall onto the guide rail. Prolonged exposure to the high temperature of these sparks can easily lead to a deterioration in the material properties of the guide rail. Therefore, in one embodiment, a second guide rail 120 and two front chuck protective plates 210 are also included. The second guide rail 120 is disposed on one side of the frame 100 and parallel to the first guide rail 110. The front chuck assembly 200 and the rear chuck assembly 300 are slidably connected to the second guide rail 120. The two front chuck protective plates 210 are respectively disposed at both ends of the front chuck assembly 200 to cover the side of the second guide rail 120 near the cutting assembly 400. The second guide rail 120 works in conjunction with the first guide rail 110 to allow the front chuck assembly 200 and the rear chuck assembly 300 to move smoothly along the length of the frame 100. By setting two front chuck protection plates 210, during the cutting process, whether the front chuck assembly 200 moves along the first guide rail 110 to the upstream or downstream of the cutting assembly 400, the two front chuck protection plates 210 can move synchronously and always cover the side of the second guide rail 120 near the cutting assembly 400. This effectively prevents sparks generated during cutting from splashing onto the second guide rail 120, avoiding damage to the guide rail due to high temperatures and other factors. This maintains the good structural condition and guiding accuracy of the guide rail, extends its service life, ensures that the chuck assembly can move smoothly and steadily on the guide rail, guarantees the smooth progress of pipe cutting, improves the overall stability and reliability of the equipment, and reduces maintenance costs and equipment downtime caused by guide rail damage.

[0023] For long or heavy pipes, relying solely on the chuck assemblies at both ends is insufficient to ensure stability throughout the cutting process, leading to pipe sagging and bending due to gravity. Therefore, in one embodiment, a follow-up support assembly 600 is included. This assembly comprises a fixed bracket 610, a third slider 620, a clamping device 630, a support device 640, a third drive device 650, and a third guide rail 660. The fixed bracket 610 is mounted on the frame 100, and the third guide rail 660 is vertically mounted on the fixed bracket 610. The third slider 620 is slidably connected to the third guide rail 660. The third drive device 650 is mounted on the fixed bracket 610 and drives the third slider 620 to reciprocate along the third guide rail 660. The support device 640 is located on the top surface of the third slider 620 and supports the bottom of the pipe. The clamping device 630 includes a fourth drive device... The device comprises a third slider 620, a horizontal bar 631, a fourth guide rail 633, a fifth guide rail 634, two clamping blocks 635, and two connecting rods 636. The fourth guide rail 633 is vertically mounted on the third slider 620, and the fifth guide rail 634 is mounted on the third slider 620 and perpendicular to the fourth guide rail 633. The horizontal bar 632 is slidably connected to the fourth guide rail 633, and both clamping blocks 635 are slidably connected to the fifth guide rail 634. One end of each connecting rod 636 is hinged to a clamping block 635, and the other end of each connecting rod 636 is hinged to the center of the horizontal bar 632. A fourth driving device 631 is mounted on the third slider 620, and the output end of the fourth driving device 631 is fixedly connected to the horizontal bar 632. The third driving device 650 drives the support device 640 and the clamping device 630 to move up and down to change the support state of the follow-up support assembly 600; the fourth driving device 631 drives the crossbar 632 to move along the fourth guide rail 633, and drives the clamping block 635 to slide along the fifth guide rail 634 through the connecting rod 636, so as to realize the clamping or release of the pipe; the support device 640 always provides stable support for the pipe, ensuring the stability and accuracy of cutting, while the clamping device 630 can firmly clamp the pipe, preventing the pipe from shifting during the cutting process and improving the cutting quality. Specifically, the third driving device 650 in this embodiment is a gear and rack drive device, or it can also be set as a linear motor, a lead screw drive device, or a linear cylinder; the fourth driving device 631 in this embodiment is a linear motor, or it can also be set as a gear and rack drive device, a lead screw drive device, or a linear cylinder; the specific structure and working principle of the support device 640 are all existing technologies and will not be described in detail here.

[0024] For long, heavy, or unevenly weighted pipes, a small number of support components are insufficient to provide sufficiently uniform and effective support. Therefore, in one embodiment, at least three sets of follow-up support components 600 are provided. All follow-up support components 600 are distributed along the length of the frame 100 between the front chuck assembly 200 and the rear chuck assembly 300, with unequal spacing between adjacent follow-up support components 600. Providing at least three sets of follow-up support components 600 allows for support at more points on the pipe, resulting in more uniform force distribution along the entire length of the pipe. This further reduces the possibility of instability such as swaying or sinking during cutting, significantly improving support stability and ensuring smooth and high-quality cutting. The unequal spacing between adjacent follow-up support components 600 allows for flexible adaptation to a wider range of pipe specifications. Pipes of different lengths and weight distributions can find a suitable support layout, enabling the equipment to handle various pipe processing tasks, no longer limited to specific pipe specifications, thus enhancing the versatility and practicality of the beveling pipe cutter.

[0025] Rust or other foreign objects from the pipe may enter the mating area between the third guide rail 660 and the third slider 620, and between the fifth guide rail 634 and the corresponding slider, causing jamming or uneven movement. Therefore, in one embodiment, each set of follower support components 600 further includes a first guard plate 670 and a second guard plate 680. The first guard plate 670 is disposed on top of the third guide rail 660, and the second guard plate 680 is disposed on top of the fifth guide rail 634. The first guard plate 670 and the second guard plate 680 can effectively prevent rust or other foreign objects from falling into the corresponding guide rail and slider mating area, keeping these critical mating parts clean, maintaining good sliding mating conditions, ensuring that each component of the follower support component 600 can operate smoothly according to design requirements, and ensuring stable equipment operation.

[0026] Relying on manual estimation or imprecise positioning methods can easily lead to significant deviations in the length of the cut pipe. Therefore, in one embodiment, a positioning component 700 is also included. The positioning component 700 includes a first sensor 710, a first cylinder 720, and a mounting bracket 730. The first cylinder 720 is mounted on the rear chuck assembly 300, and its driving direction is parallel to the extension direction of the first guide rail 110. The mounting bracket 730 is mounted on the driving end of the first cylinder 720, and the first sensor 710 is mounted on the mounting bracket 730. The first sensor 710 is electrically connected to the rear chuck assembly 300, and its detection end faces the end face of the pipe. The first cylinder 720 drives the mounting bracket 730 and the first sensor 710 to move, enabling the first sensor 710 to accurately detect the pipe end face and generate a zero-position signal. This signal is transmitted to the controller of the rear chuck assembly 300, providing a precise and reliable reference for subsequent cutting length control. This effectively improves the accuracy of the cutting length, ensuring that the processed pipe length meets design requirements and satisfies the stringent dimensional accuracy requirements of various projects. The first cylinder 720 facilitates manual zero-point calibration by the operator. The operator can flexibly adjust the sensor position according to the actual situation to accurately align it with the pipe end face to determine the zero position, enhancing the adaptability and operability of the equipment in different processing scenarios and reducing the possibility of cutting errors due to inaccurate positioning. The reversible feature of the measurement process ensures that the positioning assembly 700 will not interfere with subsequent cutting operations after completing the positioning operation, ensuring smooth cutting. This achieves both precise positioning and smooth cutting process, improving the overall working efficiency and practicality of the equipment.

[0027] Due to factors such as uneven cylinder piston movement and vibrations generated during equipment operation, the mounting bracket 730 may experience unstable movement such as swaying or offset. Therefore, in one embodiment, the positioning assembly 700 further includes a bushing 740 and a guide rod 750. The bushing 740 is fixed to the rear chuck assembly 300, and the guide rod 750 is fixed to the mounting bracket 730. The guide rod 750 and the bushing 740 are slidably connected. The guide rod 750 cooperates with the bushing 740 to provide reliable guidance for the sliding of the mounting bracket 730. When the first cylinder 720 drives the mounting bracket 730 to move, it can limit unnecessary displacement of the mounting bracket 730 in other directions, ensuring that it moves strictly in the predetermined direction. This reduces swaying and offset caused by external interference or cylinder malfunctions, making the movement of the mounting bracket 730 more stable. This ensures the overall stability of the positioning assembly 700, improves the working accuracy of the positioning assembly 700, and helps improve the dimensional accuracy of the entire beveling pipe cutter when cutting pipes, ensuring that the processed pipes meet high-quality requirements.

Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present invention, and these equivalent modifications or substitutions are all included within the scope defined by the claims of this application.
