Description

Technical Field

[0001] The present application relates to the technical field of pipe cutting, and more specifically, to a material discharging and slag removal device, a pipe cutting machine, and a control method for the pipe cutting machine. Background Art

[0002] During the pipe cutting process, impurities such as cutting slag and cutting dust usually adhere to the inner wall of the pipe. Some pipes have high requirements for the smoothness of the inner wall of the pipe. Therefore, after the pipe cutting is completed, the inner wall of the pipe needs to be cleaned. However, after the pipe cutting is completed, the slag adhered to the inner wall of the pipe will cool down quickly. The cooled slag is difficult to handle and the cleaning speed is slow. Even after the slag is removed, the inner wall of the pipe has been damaged by the slag, resulting in poor smoothness of the inner wall of the pipe.

[0003] At present, a common solution is to insert an exhaust pipe into the inner cavity of the pipe to be cut, and use the exhaust pipe to extract impurities such as slag and dust that fall during the cutting process, so as to prevent the slag from damaging the inner wall of the pipe. However, when cutting a long pipe, using this exhaust pipe to extract slag requires inserting the exhaust pipe into the pipe from the side of the pipe to be cut until the exhaust pipe is moved to the part of the pipe to be cut. This will make the exhaust pipe move back and forth for too long, resulting in low cutting efficiency. Summary of the invention

[0036] In summary, the control method of the pipe cutting machine provided in the present application can control the first exhaust pipe to retract when the second exhaust pipe is close to the cutting station or is in the process of removing slag, so that the pipe on the first exhaust pipe falls off to realize unloading.

[0050] First embodiment

[0051] like Figures 1 to 3 As shown, this embodiment provides a material unloading and slag removal device, including a controller, a conversion part 200, and a conversion drive part 110 connected to the conversion part 200. The conversion part 200 is sequentially installed with a first telescopic drive part 310 and a second telescopic drive part 410 along the first direction. The first telescopic drive part 310 is connected to a first exhaust pipe 320, and the second telescopic drive part 410 is connected to a second exhaust pipe 420. The controller is respectively connected to the conversion drive part 110, the first telescopic drive part 310, and the second telescopic drive part 410. The controller is used to control the conversion drive part 110 to drive the conversion part 200 to move along the first direction, so that the first exhaust pipe 320 or the second exhaust pipe 420 is opposite to the cutting station 11 on the pipe cutting machine in the second direction. The controller is also used to control the first telescopic drive part 310 to drive the first exhaust pipe 320 to approach or move away from the cutting station 11 along the second direction, and control the second telescopic drive part 410 to drive the second exhaust pipe 420 to approach or move away from the cutting station 11 along the second direction, and the first direction and the second direction are set at an angle. Optionally, the conversion drive unit 110, the first telescopic drive unit 310 and the second telescopic drive unit 410 may be specifically a cylinder, a linear motor or other linear drive structure, which is not limited here. Optionally, the controller may include a numerical control unit or other structure capable of controlling the conversion drive unit 110, the first telescopic drive unit 310 and the second telescopic drive unit 410 to work, which is not limited here.

[0052] In an embodiment of the present application, the controller may be disposed in the conversion section 200, or may also be disposed in other structures in the unloading and slag removal device. In one example, the unloading and slag removal device further includes a base plate 100, and the controller may be disposed in the base plate 100. When the unloading and slag removal device is applied to a pipe cutting machine, the controller may be disposed in other structures of the pipe cutting machine. Exemplarily, the pipe cutting machine includes a frame 10, and the controller is specifically disposed in the frame 10. It is worth noting that the signal connection in the embodiment of the present application may specifically be realized by wireless signal connection through a wireless communication device, or may also be realized by a data line.

[0053] In the embodiment of the present application, the first direction and the second direction can be set at any angle greater than 0 degrees. Optionally, the first direction and the second direction can be set at a 90-degree angle. For ease of description, the following text is described by taking the first direction and the second direction as an example of a 90-degree angle. In the drawings of the embodiments of the present application, the first direction is shown as the direction indicated by the AA arrow, and the second direction is shown as the direction indicated by the BB arrow.

[0054] The material removal and slag removal device provided in the embodiment of the present application can be applied to a pipe cutting machine, which has a cutting station 11 for cutting the pipe to be cut. In the embodiment of the present application, the second direction is specifically parallel to the length direction of the pipe to be cut, so that the first exhaust pipe 320 and the second exhaust pipe 420 can be inserted into the pipe to be cut when approaching the cutting station 11 along the second direction. It is worth noting that the cutting station 11 is specifically an area in the pipe cutting machine. Figure 3 The area enclosed by the circular dotted frame pointed by the dotted arrow is the cutting station 11, in which a cutting head (not shown in the figure) is arranged, that is, the cutting station 11 is specifically an area in the pipe cutting machine where a cutting head is arranged. The part to be cut of the pipe to be cut is moved to the cutting station 11, so that the part to be cut of the pipe to be cut is opposite to the cutting head of the cutting station 11, and the pipe to be cut is cut off from the original pipe body by the cutting head.

[0055] In the embodiment of the present application, the first exhaust pipe 320 and the second exhaust pipe 420 are both connected to an exhaust device, and exhaust is performed through the exhaust device to generate negative pressure in the first exhaust pipe 320 and the second exhaust pipe 420. When the first exhaust pipe 320 or the second exhaust pipe 420 moves to the cutting station 11, the first exhaust pipe 320 or the second exhaust pipe 420 can extract impurities such as slag or dust dropped during the cutting process to prevent the slag or dust from contaminating the inner wall of the pipe to be cut, thereby maintaining the smoothness of the inner wall of the pipe to be cut. Specifically, the first exhaust pipe 320 moves to the cutting station 11, which specifically refers to the end of the first exhaust pipe 320 away from the first telescopic drive unit 310 moves to the cutting station 11. Similarly, the second exhaust pipe 420 moves to the cutting station 11, which specifically refers to the end of the second exhaust pipe 420 away from the second telescopic drive unit 410 moves to the cutting station 11.

[0056] When the unloading slag removal device is applied to a pipe cutting machine, since the first telescopic driving part 310 and the second telescopic driving part 410 are sequentially installed on the conversion part 200 along the first direction, and the first telescopic driving part 310 is connected to the first exhaust pipe 320, and the second telescopic driving part 410 is connected to the second exhaust pipe 420, during the process of the pipe cutting machine cutting the pipe to be cut, the conversion part 200 can be driven to move forward along the first direction by the conversion driving part 110 under the control of the controller, so that the first exhaust pipe 320 is opposite to the cutting station 11, and the first telescopic driving part 310 drives the second exhaust pipe 420 to move forward along the first direction ... An exhaust pipe 320 is extended so that the first exhaust pipe 320 moves along the second direction to the cutting station 11 and extracts impurities dropped during the cutting process (this is the slag removal process); when the pipe to be cut is cut off from the original pipe body, the conversion drive unit 110 drives the conversion unit 200 to move in the opposite direction along the first direction, so that the second exhaust pipe 420 is opposite to the cutting station 11, and the second exhaust pipe 420 is driven to extend through the second telescopic drive unit 410, so that the second exhaust pipe 420 moves along the second direction to the cutting station 11 and extracts impurities dropped during the next cutting process. The first telescopic driving unit 310 can drive the first exhaust duct 320 to retract when the second exhaust duct 420 approaches the cutting station 11 along the second direction or when the second exhaust duct 420 is removing slag, that is, when the second exhaust duct 420 approaches the cutting station 11 along the second direction or when the second exhaust duct 420 is removing slag, the first exhaust duct 320 can be driven to move away from the cutting station 11 along the second direction so that the pipe on the first exhaust duct 320 falls off and prepare for slag removal for the next cutting process, and vice versa.

[0057] In summary, the material unloading and slag removal device provided in the embodiment of the present application can control the first exhaust pipe 320 to retract when the second exhaust pipe 420 is close to the cutting station 11 or is in the process of slag removal, so that the pipe on the first exhaust pipe 320 falls off to realize unloading. Similarly, the second exhaust pipe 420 can be controlled to retract when the first exhaust pipe 320 is close to the cutting station 11 or is in the process of slag removal, so that the pipe on the second exhaust pipe 420 falls off to realize unloading. In this way, the unloading time is saved and the cutting efficiency is effectively improved.

[0058] In one possible design, Figure 1 or Figure 2As shown, the first exhaust pipe 320 is connected to the first stopper 330, and the second exhaust pipe 420 is connected to the second stopper 430. The material removal device also includes a first limit drive 610 and a second limit drive 710, the first limit drive 610 is connected to the first limit end 620, and the second limit drive 710 is connected to the second limit end 720. Optionally, the first limit drive 610 and the second limit drive 710 can be a cylinder, a linear motor or other linear drive structure, which is not limited here. In this embodiment, the first stopper 330 on the first exhaust pipe 320 can move synchronously along the second direction with the first exhaust pipe 320, and the second stopper 430 on the second exhaust pipe 420 can move synchronously along the second direction with the second exhaust pipe 420.

[0059] The first limit drive part 610 and the second limit drive part 710 are both connected to the controller signal, and the controller is also used to control the first limit drive part 610 to drive the first limit end 620 to move to the side of the first stop part 330 close to the cutting station 11 in the second direction, and control the second limit drive part 710 to drive the second limit end 720 to move to the side of the second stop part 430 close to the cutting station 11 in the second direction.

[0060] Optionally, when the unloading and slag removal device is applied to the pipe cutting machine, such as Figure 1 or Figure 2 As shown, the first limit end 620 can be opposite to the first stop portion 330 in the second direction, and the first limit end 620 is located on the side of the first stop portion 330 close to the cutting station 11 in the second direction, and the first limit drive portion 610 is used to drive the first limit end 620 to move along the second direction toward the side close to the first stop portion 330, and the first limit end 620 is used to limit the shortest distance between the first stop portion 330 and the cutting station 11 in the second direction, thereby limiting the shortest distance between the first exhaust pipe 320 and the cutting station 11 in the second direction. The second limit end 720 can be opposite to the second stop portion 430 in the second direction, and the second limit end 720 is located on the side of the second stop portion 430 close to the cutting station 11 in the second direction, and the second limit driving portion 710 is used to drive the second limit end 720 to move along the second direction toward the side close to the second stop portion 430, and the second limit end 720 is used to limit the shortest distance between the second stop portion 430 and the cutting station 11 in the second direction, thereby limiting the shortest distance between the second exhaust pipe 420 and the cutting station 11 in the second direction.

[0061] With such arrangement, when the first exhaust pipe 320 approaches the cutting station 11 along the second direction or is removing slag, the controller can control the second telescopic driving part 410 to drive the second exhaust pipe 420 to move along the second direction toward the side close to the cutting station 11 until the second stop part 430 contacts the second limit end 720, so that the second exhaust pipe 420 is first located close to the cutting station 11. After the pipe to be cut into which the first exhaust pipe 320 is inserted is cut, the conversion drive unit 110 drives the conversion unit 200 to move in the opposite direction along the first direction, so that the second exhaust pipe 420 is opposite to the cutting station 11 in the second direction. Since the second exhaust pipe 420 is already located close to the cutting station 11, the controller only needs to control the second limit drive unit 710 to drive the second limit end 720 to move along the second direction toward the side away from the second stop unit 430, and then control the second telescopic drive unit 410 to drive the second exhaust pipe 420 to move a shorter distance along the second direction toward the side close to the cutting station 11, so that the second exhaust pipe 420 can be moved to the cutting station 11. In this way, the time for the second exhaust pipe 420 to move to the cutting station 11 after being opposite to the cutting station 11 in the second direction is shortened, thereby improving the cutting efficiency. Similarly, when the second exhaust pipe 420 is approaching the cutting station 11 along the second direction or when slag removal is being performed, the controller can control the first telescopic driving part 310 to drive the first exhaust pipe 320 to move along the second direction toward the side close to the cutting station 11 until the first stop part 330 contacts the first limit end 620, so that the first exhaust pipe 320 is located close to the cutting station 11. In this way, the time when the first exhaust pipe 320 and the cutting station 11 are relative to each other in the second direction and move to the cutting station 11 can be shortened, thereby effectively improving the cutting efficiency.

[0062] Optionally, the first limit end 620 may not be opposite to the first stop portion 330 in the second direction. Specifically, when the unloading slag removal device is applied to the pipe cutting machine, in the second direction, the first limit end 620 is located between the first stop portion 330 and the cutting station 11, and the first limit end 620 and the first stop portion 330 are spaced apart in the third direction, and the second direction is set at an angle to the third direction. The first limit drive portion 610 is used to drive the first limit end 620 to move along the third direction, so that the first limit end 620 is opposite to the first stop portion 330 in the second direction, and the first limit end 620 is located on the side of the first stop portion 330 close to the cutting station 11 in the second direction, so that the shortest distance between the first stop portion 330 and the cutting station 11 in the second direction can also be limited by the first limit end 620. Optionally, the third direction can be set perpendicular to the second direction. In one example, the third direction can be set parallel to the first direction. Optionally, the second limit end 720 may not be opposite to the second stop portion 430 in the second direction. Specifically, when the unloading slag removal device is applied to the pipe cutting machine, in the second direction, the second limit end 720 is located between the second stop portion 430 and the cutting station 11, and the second limit end 720 and the second stop portion 430 are spaced apart in the third direction. The second limit drive portion 710 is used to drive the second limit end 720 to move along the third direction, so that the second limit end 720 and the second stop portion 430 are opposite in the second direction, and the second limit end 720 is located on the side of the second stop portion 430 close to the cutting station 11 in the second direction. In this way, the shortest distance between the second stop portion 430 and the cutting station 11 in the second direction can also be limited by the second limit end 720.

[0063] In one possible design, Figure 1 or Figure 2As shown, the material unloading and slag removal device also includes a first sensing mechanism 510 and a second sensing mechanism 520. The first sensing mechanism 510 is arranged corresponding to the first stopper 330, and the first sensing mechanism 510 is configured to sense the position of the first stopper 330 in the second direction. The second sensing mechanism 520 is arranged corresponding to the second stopper 430, and the second sensing mechanism 520 is configured to sense the position of the second stopper 430 in the second direction. The first sensing mechanism 510 and the second sensing mechanism 520 are respectively connected to the controller signal. The first sensing mechanism 510 is used to feed back the position information of the first stopper 330 to the controller, and the second sensing mechanism 520 is used to feed back the position information of the second stopper 430 to the controller. The controller is also used to control the first telescopic drive unit 310 or the second telescopic drive unit 410 to move, or control the first telescopic drive unit 310 and the second telescopic drive unit 410 to move according to the information fed back by the first sensing mechanism 510 and the second sensing mechanism 520. It is worth noting that the action of the first telescopic driving unit 310 specifically refers to the first telescopic driving unit 310 driving the first exhaust pipe 320 to move along the second direction, and the action of the second telescopic driving unit 410 specifically refers to the second telescopic driving unit 410 driving the second exhaust pipe 420 to move along the second direction. In this embodiment, the first sensing mechanism 510 and the second sensing mechanism 520 are both installed on the conversion unit 200, and the first sensing mechanism 510 is corresponding to the first stopper 330 on the first exhaust pipe 320, and the second sensing mechanism 520 is corresponding to the second stopper 430 on the second exhaust pipe 420.

[0064] According to the above technical solution, the positions of the first stop portion 330 and the second stop portion 430 in the second direction are respectively sensed by the first sensing mechanism 510 and the second sensing mechanism 520 to monitor the positions of the first exhaust pipe 320 and the second exhaust pipe 420 in the second direction, so that the first exhaust pipe 320 and the second exhaust pipe 420 can alternately remove slag and discharge materials efficiently and orderly. Exemplarily, during operation, when the first exhaust pipe 320 is opposite to the cutting station 11 in the second direction, and the end of the first exhaust pipe 320 away from the first telescopic drive unit 310 is not at the cutting station 11, the controller controls the second telescopic drive unit 410 to drive the second exhaust pipe 420 to move along the second direction toward the side away from the cutting station 11; when the second exhaust pipe 420 moves along the second direction toward the side away from the cutting station 11 to the first predetermined position, it indicates that the pipe to be cut on the second exhaust pipe 420 has been successfully unloaded, and the second sensing mechanism 520 feeds back the current position of the second stop portion 430 on the second exhaust pipe 420 to the controller; after receiving the information fed back by the second sensing mechanism 520, the controller can control the first telescopic drive unit 310 to drive the first exhaust pipe 320 to move along the second direction to the cutting station 11, so that the first exhaust pipe 320 can remove slag. Similarly, during operation, when the second exhaust pipe 420 is opposite to the cutting station 11 in the second direction, and the end of the second exhaust pipe 420 away from the second telescopic drive unit 410 is not at the cutting station 11, the controller controls the first telescopic drive unit 310 to drive the first exhaust pipe 320 to move along the second direction toward the side away from the cutting station 11; when the first exhaust pipe 320 moves to the second predetermined position along the second direction toward the side away from the cutting station 11, it indicates that the pipe to be cut on the first exhaust pipe 320 has been successfully unloaded, and the first sensing mechanism 510 feeds back the current position of the first stopper 330 on the first exhaust pipe 320 to the controller; after receiving the information fed back by the first sensing mechanism 510, the controller can control the second telescopic drive unit 410 to drive the second exhaust pipe 420 to move along the second direction to the cutting station 11, so that the first exhaust pipe 320 can remove slag.

[0065] Optionally, the first sensing mechanism 510 and the second sensing mechanism 520 may include a laser distance sensor, a photoelectric sensor, or other structures that can be used to sense the position of a component. In one example, the first sensing mechanism 510 includes a plurality of first photoelectric sensors spaced apart along the second direction, and the plurality of first photoelectric sensors are respectively connected to the controller signal. Figure 4As shown, the first stop portion 330 includes a first body and a first shading sheet 332 that are interconnected. The first shading sheet 332 is arranged parallel to the second direction. The first body is installed on the first exhaust pipe 320. The first body is used to contact the first limit end 620. The first shading sheet 332 can move along the second direction synchronously with the first body and the first exhaust pipe 320. The first shading sheet 332 moves between multiple first photoelectric sensors driven by the first exhaust pipe 320. When the first shading sheet 332 moves to different first photoelectric sensors, the first shading sheet 332 will block the light in the current first photoelectric sensor so that the first photoelectric sensor can feed back a signal to the controller, thereby realizing the function of the first sensing mechanism 510 sensing the position of the first stop portion 330 in the second direction. The second sensing structure includes multiple second photoelectric sensors spaced apart along the second direction, and the multiple second photoelectric sensors are respectively connected to the controller signal. As shown Figure 2 As shown, the second stopper 430 includes a second body and a second light shielding sheet 432 connected to each other, the second light shielding sheet 432 is arranged parallel to the second direction, the second body is mounted on the second exhaust pipe 420, the second body is used to contact the second limit end 720, the second light shielding sheet 432 can move synchronously along the second direction with the second body and the second exhaust pipe 420, and the second light shielding sheet 432 moves between the plurality of second photoelectric sensors driven by the second exhaust pipe 420. When the second light shielding sheet 432 moves to a different second photoelectric sensor, the second light shielding sheet 432 will shield the light in the second photoelectric sensor currently located, so that the second photoelectric sensor feeds back a signal to the controller, thereby realizing the function of the second sensing mechanism 520 sensing the position of the second stopper 430 in the second direction.

[0066] In a specific embodiment, Figure 1 and Figure 3As shown, the number of first photoelectric sensors is three, and the three first photoelectric sensors are respectively the first photoelectric sensor a511, the first photoelectric sensor b512 and the first photoelectric sensor c513. The first photoelectric sensor a511, the first photoelectric sensor b512 and the first photoelectric sensor c513 are spaced apart along the second direction. The first photoelectric sensor a511 is located on the side of the first photoelectric sensor b512 close to the cutting station 11, and the first photoelectric sensor c513 is located on the side of the first photoelectric sensor b512 away from the cutting station 11. When one end of the first exhaust pipe 320 away from the first telescopic drive part 310 is located at the cutting station 11, the first shading sheet 332 just moves to the first photoelectric sensor a511; when the first limit drive part 610 drives the first limit end 620 to move to the side of the first stop part 330 close to the cutting station 11 in the second direction, and the first main body 331 of the first stop part 330 contacts the first limit end 620, the first shading sheet 332 just moves to the first photoelectric sensor b512; when the first exhaust pipe 320 moves to the second predetermined position along the second direction toward the side away from the cutting station 11, the first shading sheet 332 just moves to the first photoelectric sensor c513.

[0067] In a specific embodiment, Figure 1 and Figure 3 As shown, the number of second photoelectric sensors is three, and the three second photoelectric sensors are respectively a second photoelectric sensor d521, a second photoelectric sensor e522 and a second photoelectric sensor f523. The second photoelectric sensor d521, the second photoelectric sensor e522 and the second photoelectric sensor f523 are spaced apart along the second direction. The second photoelectric sensor d521 is located on the side of the second photoelectric sensor e522 close to the cutting station 11, and the second photoelectric sensor f523 is located on the side of the second photoelectric sensor e522 away from the cutting station 11. When one end of the second exhaust pipe 420 away from the second telescopic drive part 410 is located at the cutting station 11, the second shading sheet 432 just moves to the second photoelectric sensor d521; when the second limit drive part 710 drives the second limit end 720 to move to the side of the second stop part 430 close to the cutting station 11 in the second direction, and the second main body 431 of the second stop part 430 contacts the second limit end 720, the second shading sheet 432 just moves to the second photoelectric sensor e522; when the second exhaust pipe 420 moves to the first predetermined position along the second direction toward the side away from the cutting station 11, the second shading sheet 432 just moves to the second photoelectric sensor f523.

[0068] In one possible design, Figure 1 , Figure 3 and Figure 5As shown, a first notch 321 is provided at one end of the first exhaust pipe 320 away from the first telescopic driving part 310, and the first notch 321 is communicated with the inner cavity of the first exhaust pipe 320. The controller is used to control the first telescopic driving part 310 to drive the first exhaust pipe 320 to approach the cutting station 11 along the second direction, so that the first notch 321 is opposite to the cutting head in the cutting station 11. In this embodiment, when the end of the first exhaust pipe 320 away from the first telescopic driving part 310 moves to the cutting station 11, the first notch 321 is opposite to the cutting head, so that the first exhaust pipe 320 can extract impurities generated during the cutting process.

[0069] In one possible design, Figure 1 and Figure 3 As shown, the second exhaust pipe 420 is provided with a second notch at one end away from the second telescopic drive unit 410, and the second notch is connected to the inner cavity of the second exhaust pipe 420. The controller is used to control the second telescopic drive unit 410 to drive the second exhaust pipe 420 to approach the cutting station 11 along the second direction, so that the second notch is opposite to the cutting head in the cutting station 11. Similarly, in this embodiment, when the second exhaust pipe 420 moves to the cutting station 11 away from the end of the second telescopic drive unit 410, the second notch is opposite to the cutting head, so that the second exhaust pipe 420 can extract impurities generated during the cutting process. It is worth noting that this embodiment can be implemented on the premise that the first exhaust pipe 320 is provided with a first notch 321 at one end away from the first telescopic drive unit 310 in the above embodiment. That is to say, when the first exhaust pipe 320 is provided with the first notch 321, the second exhaust pipe 420 can be provided with a second notch, or it can be provided with no second notch, which is not limited to this.

[0070] In one possible design, Figures 1 to 3 As shown, the material unloading and slag removal device also includes a bottom plate 100 and a linear guide rail 120 installed on the bottom plate 100, the conversion drive unit 110 is installed on the bottom plate 100, and the conversion unit 200 is slidably installed on the linear guide rail 120 along the first direction. In this arrangement, by providing the linear guide rail 120, a guiding effect is played for the movement of the conversion unit 200 along the first direction, which is conducive to improving the smoothness of the movement of the conversion unit 200 along the first direction.

[0071] In a specific embodiment, Figure 4As shown, the conversion part 200 includes a mounting plate 210 and a slider 220, the slider 220 is mounted on a side of the mounting plate 210 facing the bottom plate 100, the slider 220 and the linear guide 120 slide in cooperation along the first direction, and the first telescopic drive part 310, the second telescopic drive part 410, the first limit drive part 610, the second limit drive part 710, the first sensing mechanism 510 and the second sensing mechanism 520 are all mounted on a side of the mounting plate 210 away from the bottom plate 100. Optionally, the number of the sliders 220 and the linear guide 120 are both multiple, and the multiple linear guides 120 are installed on the bottom plate 100 at intervals along the second direction, and the multiple sliders 220 are arranged one-to-one with the multiple linear guides 120, and each slider 220 is slidably installed on the corresponding linear guide 120 along the first direction. In an example, the number of the sliders 220 and the linear guide 120 are both two.

[0072] In one possible design, Figure 2 and Figure 4 As shown, the conversion part 200 is connected to a baffle 130 on one side close to the cutting station 11 in the second direction, and the baffle 130 is penetrated by a first through hole 131 and a second through hole 132 along the second direction. The first exhaust pipe 320 is penetrated through the first through hole 131, and the second exhaust pipe 420 is penetrated through the second through hole 132. The material unloading and slag removal device is applied to the pipe cutting machine. When the first telescopic driving part 310 drives the first exhaust pipe 320 to approach the cutting station 11 along the second direction, it is specifically manifested as follows: at least part of the structure of the first exhaust pipe 320 extends through the first through hole 131 to the side of the baffle 130 close to the cutting station 11; when the first telescopic driving part 310 drives the first exhaust pipe 320 to move away from the cutting station 11 along the second direction, it is specifically manifested as follows: at least part of the structure of the first exhaust pipe 320 retracts through the first through hole 131 to the side of the baffle 130 away from the cutting station 11, and the pipe to be cut on the first exhaust pipe 320 stays on the side of the baffle 130 close to the cutting station 11 under the blocking action of the baffle 130, so that the pipe to be cut slides off the first exhaust pipe 320. Similarly, the second exhaust pipe 420 can be moved along the second direction under the drive of the second telescopic driving part 410, so as to extend through the second through hole 132 to the side of the baffle 130 close to the cutting station 11, and retract to the side of the baffle 130 away from the cutting station 11. The pipe to be cut on the second exhaust pipe 420 stays on the side of the baffle 130 close to the cutting station 11 under the blocking effect of the baffle 130, so as to facilitate the pipe to be cut to slide off the second exhaust pipe 420.

[0073] Second embodiment

[0074] This embodiment provides a pipe cutting machine, such as Figure 3As shown, the pipe cutting machine includes a frame 10 and a material unloading and slag removal device provided in any of the above embodiments, a cutting station 11 is provided on the frame 10, a conversion drive unit 110 is installed on the frame 10, and a conversion unit 200 is slidably installed on the frame 10 along a first direction. Since the pipe cutting machine provided in this embodiment includes the material unloading and slag removal device provided in any of the above embodiments, it has at least all the above beneficial effects, which will not be repeated here.

[0075] Optionally, the conversion drive unit 110 can be directly or indirectly connected to the frame 10, so that the conversion drive unit 110 is installed on the frame 10. In one example, when the lower material slag removal device further includes a bottom plate 100, the conversion drive unit 110 is specifically installed on the frame 10 through the bottom plate 100. In another example, when the lower material slag removal device does not include a bottom plate 100, the conversion drive unit 110 can be directly installed on the frame 10.

[0076] In some embodiments, the pipe cutting machine further includes a cutting head, which is mounted on the frame 10, and at least a portion of the structure of the cutting head is located at the cutting station 11. The cutting head is connected to the controller signal, and the controller controls the cutting head to cut the pipe to be cut at the cutting station 11. The cutting head can be a laser cutting head or other cutting heads that can be used for cutting pipes, which is not limited here.

[0077] In some embodiments, the pipe cutting machine further comprises a feeding mechanism, which is mounted on the frame 10. The feeding mechanism is used to clamp the pipe and convey the pipe to the cutting station 11, and is also used to drive the pipe to rotate around its own length direction. It is worth noting that the pipe located at the cutting station 11 and the structure on the side of the cutting station 11 away from the feeding mechanism is the pipe to be cut, and the pipe located at the side of the cutting station 11 close to the feeding mechanism and the structure located in the feeding mechanism are the original pipe body. It is worth noting that when the first exhaust pipe 320 is already located near the cutting station 11, and the conversion drive unit 110 drives the conversion unit 200 to move forward along the first direction, so that the first exhaust pipe 320 and the cutting station 11 are opposite in the second direction, the pipe in the pipe cutting machine moves along the second direction to the direction close to the first exhaust pipe 320 under the drive of the feeding mechanism, and is sleeved on the outer periphery of the first exhaust pipe 320, so that the first exhaust pipe 320 is inserted into the pipe to be cut. When the second exhaust pipe 420 is first located near the cutting station 11, and the conversion drive unit 110 drives the conversion unit 200 to move in the opposite direction along the first direction, so that the second exhaust pipe 420 and the cutting station 11 are opposite to each other in the second direction, the pipe in the pipe cutting machine is driven by the feeding mechanism to move along the second direction toward the second exhaust pipe 420 and is sleeved on the outer periphery of the second exhaust pipe 420, so that the second exhaust pipe 420 is inserted into the pipe to be cut.

[0078] Third embodiment

[0079] This embodiment provides a control method for a pipe cutting machine, which is applicable to the pipe cutting machine provided by any of the above embodiments. The control method for the pipe cutting machine includes:

[0080] S10, controlling the conversion driving unit 110 to drive the conversion unit 200 to move forward along the first direction, so that the first exhaust pipe 320 and the cutting station 11 are opposite to each other in the second direction.

[0081] S20, controlling the first telescopic driving part 310 to drive the first exhaust pipe 320 to approach the cutting station 11 along the second direction until the first exhaust pipe 320 is inserted into the pipe to be cut on the frame 10 and moves to the cutting station 11.

[0082] S30, controlling the cutting head in the cutting station 11 to cut the pipe to be cut, and controlling the first exhaust pipe 320 to extract impurities dropped during the cutting process.

[0083] S40, after the pipe to be cut is cut, the conversion drive unit 110 is controlled to drive the conversion unit 200 to move in the opposite direction along the first direction, so that the second exhaust pipe 420 and the cutting station 11 are opposite to each other in the second direction.

[0084] S50, controlling the first telescopic driving part 310 to drive the first exhaust pipe 320 to move away from the cutting station 11 along the second direction, so that the first exhaust pipe 320 is moved out from the cut pipe to be cut.

[0085] S60, controlling the second telescopic driving part 410 to drive the second exhaust pipe 420 to approach the cutting station 11 along the second direction until the second exhaust pipe 420 is inserted into the pipe to be cut on the frame 10 and moves to the cutting station 11.

[0086] S70, controlling the cutting head in the cutting station 11 to cut the pipe to be cut on the frame 10, and controlling the second exhaust pipe 420 to extract impurities dropped during the cutting process.

[0087] S80, after the pipe to be cut is cut, the conversion drive unit 110 is controlled to drive the conversion unit 200 to move forward along the first direction, so that the first exhaust pipe 320 and the cutting station 11 are opposite to each other in the second direction.

[0088] S90, controlling the second telescopic driving part 410 to drive the second exhaust pipe 420 to move away from the cutting station 11 along the second direction, so that the second exhaust pipe 420 is moved out from the cut pipe to be cut.

[0089] The control method of the pipe cutting machine provided in the embodiment of the present application is as follows: during the process of the pipe cutting machine cutting the pipe to be cut, the conversion part 200 is driven by the conversion drive part 110 to move forward along the first direction, so that the first exhaust pipe 320 is opposite to the cutting station 11, and the first exhaust pipe 320 is driven to extend by the first telescopic drive part 310, so that the first exhaust pipe 320 is moved to the cutting station 11 along the second direction, and impurities dropped during the cutting process are extracted (this is the slag removal process); when the pipe to be cut is cut off from the original pipe body, the conversion part 200 is driven by the conversion drive part 110 to move in the opposite direction along the first direction, so that the second exhaust pipe 420 is opposite to the cutting station 11, and the second exhaust pipe 420 is driven to extend by the second telescopic drive part 410, so that the second exhaust pipe 420 is moved to the cutting station 11 along the second direction, and impurities dropped during the next cutting process are extracted. The first telescopic driving unit 310 can drive the first exhaust duct 320 to retract when the second exhaust duct 420 approaches the cutting station 11 along the second direction or when the second exhaust duct 420 is removing slag, that is, when the second exhaust duct 420 approaches the cutting station 11 along the second direction or when the second exhaust duct 420 is removing slag, the first exhaust duct 320 can be driven to move away from the cutting station 11 along the second direction so that the pipe on the first exhaust duct 320 falls off and prepare for slag removal for the next cutting process, and vice versa.

[0090] In summary, the control method of the pipe cutting machine provided in the embodiment of the present application can control the first exhaust pipe 320 to retract when the second exhaust pipe 420 is close to the cutting station 11 or is in the process of removing slag, so that the pipe on the first exhaust pipe 320 falls off to achieve unloading. Similarly, the second exhaust pipe 420 can be controlled to retract when the first exhaust pipe 320 is close to the cutting station 11 or is in the process of removing slag, so that the pipe on the second exhaust pipe 420 falls off to achieve unloading. In this way, the unloading time is saved and the cutting efficiency is effectively improved.

[0091] In some embodiments, steps S10 to S90 may be performed cyclically. Optionally, step S50 may be performed simultaneously with step S40 or step S60, and step S90 may be performed simultaneously with step S80 or step S20. In this way, the cutting efficiency may be further improved.

[0092] In some embodiments, when the pipe cutting machine further includes a feeding mechanism, the feeding mechanism is connected to the controller signal, and the control method of the pipe cutting machine further includes:

[0093] The feeding mechanism is controlled to drive the pipe to move along the second direction, so as to move the pipe section to be cut to the cutting station 11 and the side of the cutting station 11 away from the feeding mechanism. This step can be performed after step S40 or step S80.

[0094] In a possible design, when the first exhaust pipe 320 is connected to the first stopper 330, the second exhaust pipe 420 is connected to the second stopper 430, and the material removal and slag removal device further includes a first limit drive 610 and a second limit drive 710, the first limit drive 610 is connected to the first limit end 620, and the second limit drive 710 is connected to the second limit end 720, the control method further includes:

[0095] When the first exhaust pipe 320 is opposite to the cutting station 11 in the second direction, the second limit driving part 710 is controlled to drive the second limit end 720 to extend, so that the second limit end 720 moves to the side of the second stop part 430 close to the cutting station 11 in the second direction, and the second telescopic driving part 410 is controlled to drive the second exhaust pipe 420 to approach the cutting station 11 along the second direction until the second stop part 430 contacts the second limit end 720. It is worth noting that the second limit driving part 710 drives the second limit end 720 to extend, which specifically refers to the second limit driving part 710 driving the second limit end 720 to move in the direction close to the second stop part 430. For example, the second limit driving part 710 drives the second limit end 720 to move in the second direction or the third direction to the side close to the second stop part 430, so that the second limit end 720 can contact the second stop part 430. In this way, when the first exhaust pipe 320 approaches the cutting station 11 along the second direction or is removing slag, the second exhaust pipe 420 can be moved to a position close to the cutting station 11 first, so that after the pipe to be cut on the first exhaust pipe 320 is cut off from the original pipe body, the second exhaust pipe 420 can be quickly moved to the cutting station 11, thereby effectively improving the cutting efficiency.

[0096] When the second exhaust pipe 420 is opposite to the cutting station 11 in the second direction, the first limit driving part 610 is controlled to drive the first limit end 620 to extend, so that the first limit end 620 moves to the side of the first stop part 330 close to the cutting station 11 in the second direction, and the first telescopic driving part 310 is controlled to drive the first exhaust pipe 320 to approach the cutting station 11 along the second direction until the first stop part 330 contacts the first limit end 620. It is worth noting that the first limit driving part 610 drives the first limit end 620 to extend, which specifically refers to the first limit driving part 610 driving the first limit end 620 to move in the direction close to the first stop part 330. For example, the first limit driving part 610 drives the first limit end 620 to move in the second direction or the third direction to the side close to the first stop part 330, so that the first limit end 620 can contact the first stop part 330. In this way, when the second exhaust pipe 420 approaches the cutting station 11 along the second direction or is removing slag, the first exhaust pipe 320 can be moved to a position close to the cutting station 11 first, so that after the pipe to be cut on the second exhaust pipe 420 is cut off from the original pipe body, the first exhaust pipe 320 can be quickly moved to the cutting station 11, thereby effectively improving the cutting efficiency.

[0097] In a possible design, when the unloading slag removal device further includes a first sensing mechanism 510 and a second sensing mechanism 520, the first sensing mechanism 510 is arranged corresponding to the first stopper 330, and the first sensing mechanism 510 is arranged corresponding to the first stopper 330; and the first sensing mechanism 510 is configured to sense the position of the first stopper 330 in the second direction, and the second sensing mechanism 520 is configured to sense the position of the second stopper 430 in the second direction, the control method further includes:

[0098] When the first exhaust pipe 320 is opposite to the cutting station 11 in the second direction, the second telescopic driving part 410 is first controlled to drive the second exhaust pipe 420 away from the cutting station 11 in the second direction until the second exhaust pipe 420 moves to the first predetermined position, and the second exhaust pipe 420 moves out of the cut pipe to be cut. According to the position information of the second stopper 430 fed back by the second sensing mechanism 520, the second telescopic driving part 410 is controlled to drive the second exhaust pipe 420 to approach the cutting station 11 in the second direction until the second stopper 430 contacts the second limit end 720, and the first limit driving part 610 is controlled to drive the first limit end 620 to retract, and the first telescopic driving part 310 is controlled to drive the first exhaust pipe 320 to move to the cutting station 11 in the second direction. It can be understood that the second stopper 430 contacts the second limit end 720, indicating that the second exhaust pipe 420 and the cutting station 11 are spaced apart in the first direction, and the second exhaust pipe 420 is located at a position relatively close to the cutting station 11 in the second direction. It is worth noting that the first limit drive 610 drives the first limit end 620 to retract, which specifically means that the first limit drive 610 drives the first limit end 620 to move in a direction away from the first stopper 330. For example, the first limit drive 610 drives the first limit end 620 to move in the second direction or the third direction to a side away from the first stopper 330. When the pipe to be cut into which the second exhaust pipe 420 is inserted is cut, the conversion drive 110 drives the conversion part 200 to move forward in the first direction, so that after the first exhaust pipe 320 and the cutting station 11 are opposite in the second direction, the first exhaust pipe 320 can move to the cutting station 11 in a shorter time. Therefore, such an arrangement can ensure that the pipe to be cut on the second exhaust pipe 420 can be unloaded smoothly, and then the first limit end 620 can be retracted, so that the first exhaust pipe 320 can be driven by the first telescopic drive part 310 to move to the cutting station 11, and then the cutting head is controlled to cut, and the first exhaust pipe 320 is controlled to remove slag.

[0099] When the second exhaust pipe 420 is opposite to the cutting station 11 in the second direction, the first telescopic driving part 310 is first controlled to drive the first exhaust pipe 320 away from the cutting station 11 in the second direction until the first exhaust pipe 320 moves to the second predetermined position, and the first exhaust pipe 320 is removed from the cut pipe to be cut. According to the position information of the first stopper 330 fed back by the first sensing mechanism 510, the first telescopic driving part 310 is controlled to drive the first exhaust pipe 320 to approach the cutting station 11 in the second direction until the first stopper 330 contacts the first limit end 620, and the second limit driving part 710 is controlled to drive the second limit end 720 to retract, and the second telescopic driving part 410 is controlled to drive the second exhaust pipe 420 to move to the cutting station 11 in the second direction. It can be understood that the first stopper 330 contacts the first limit end 620, indicating that the first exhaust pipe 320 and the cutting station 11 are spaced apart in the first direction, and the first exhaust pipe 320 is located relatively close to the cutting station 11 in the second direction. It is worth noting that the second limit drive 710 drives the second limit end 720 to retract, which specifically means that the second limit drive 710 drives the second limit end 720 to move in a direction away from the second stopper 430. For example, the second limit drive 710 drives the second limit end 720 to move in the second direction or the third direction to a side away from the second stopper 430. When the pipe to be cut into which the first exhaust pipe 320 is inserted is cut, the conversion drive 110 drives the conversion part 200 to move in the opposite direction in the first direction, so that after the second exhaust pipe 420 and the cutting station 11 are opposite in the second direction, the second exhaust pipe 420 can move to the cutting station 11 in a relatively short time in the second direction. Therefore, such an arrangement can ensure that the pipe to be cut that is cut off on the first exhaust pipe 320 can be unloaded smoothly, and then the second limit end 720 can be retracted, so that the second exhaust pipe 420 can be driven by the second telescopic drive part 410 to move to the cutting station 11, and then the cutting head is controlled to cut, and the second exhaust pipe 420 is controlled to remove slag.

[0100] It can be seen from the above that, through the above-mentioned arrangement, the first exhaust duct 320 and the second exhaust duct 420 can alternately remove slag and discharge materials efficiently and orderly, which not only improves the safety and reliability of the working process, but also improves the cutting efficiency.

[0101] The above description is only an optional embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
