Description

Fully automatic CNC pipe cutting machine Technical Field

[0001] This invention relates to the field of pipe cutting machine technology, and in particular to a fully automatic CNC pipe cutting machine. Background Technology

[0002] Pipe cutting machines, as a common industrial processing equipment, are widely used for cutting metal and plastic pipes to a fixed length. In the production of products such as fitness equipment handles, furniture fittings, and industrial equipment support pipes, it is necessary to cut long pipes that are continuously supplied into sections.

[0003] Currently, for small-batch or specific workpiece pipe cutting, manual operation or semi-automatic equipment is commonly used. A typical operating procedure is as follows: the operator manually feeds the long pipe into a simple clamping fixture for positioning, then starts the cutting device (such as an abrasive wheel saw or band saw) to cut it. After completion, the workpiece is manually removed, and measurements are taken to prepare for the next section of cutting. This method has the following significant drawbacks and shortcomings: low automation and low production efficiency, poor positioning accuracy and unstable product quality, high labor intensity and safety hazards, harsh working environment and difficulty in waste collection.

[0004] To address these issues, some highly automated pipe cutting equipment has emerged in the market. However, these equipment are typically complex in structure, expensive, or fail to effectively solve the problems of rigid support and vibration suppression of pipes during the cutting process. In particular, they are still insufficient in achieving synchronization with the upstream production line and efficient continuous operation.

[0005] Therefore, there is an urgent need in this field for a CNC pipe cutting machine that can achieve fully automatic, high-precision, and high-efficiency cutting, seamlessly connect with upstream production equipment, and improve the working environment. Summary of the Invention

[0006] Therefore, it is necessary to provide a fully automatic CNC pipe cutting machine to address the technical problems of insufficient automation and precision in existing pipe cutting equipment.

[0007] A fully automatic CNC pipe cutting machine includes a housing, a traction device, a pipe clamping device, a positioning device, a sawing device, and a discharge device. The traction device, pipe clamping device, positioning device, sawing device, and discharge device are all installed inside the housing.

[0008] The box body is equipped with a working chamber, which is located at the top of the box body to form an installation and processing space with a certain volume; the discharge device is installed at the bottom of the working chamber; the positioning device, traction device and clamping device are located on the top side of the discharge device, and the clamping device, traction device and positioning device are arranged in sequence from one end of the working chamber to the other end.

[0009] The positioning device includes a first guide rail module and a positioning structure. The first guide rail module extends along the conveying direction of the pipe, and the positioning structure is installed on the movable end surface of the first guide rail module corresponding to the conveying path of the pipe.

[0010] In one embodiment, the positioning structure includes a first connecting seat and a positioning member. The first connecting seat is connected to the movable end surface of the first guide rail module. One end of the positioning member is hinged to the side surface of the first connecting seat facing away from the first guide rail module, and the other end of the positioning member extends a predetermined distance away from the first guide rail module, so that the positioning member can be correspondingly set with the traction end of the traction device and the clamping end of the clamping device.

[0011] In one embodiment, the end of the positioning member facing away from the first connecting seat is configured as a sleeve positioning structure that corresponds to and cooperates with the end of the pipe.

[0012] In one embodiment, the first guide rail module described above is configured as an electric slide.

[0013] In one embodiment, the traction device includes a second guide rail module and a cylinder gripper. The second guide rail module extends along a preset pipe conveying direction and is disposed on the top side of the first guide rail module. The cylinder gripper is connected to the movable end surface of the second guide rail module to clamp and traction the incoming pipe material.

[0014] In one embodiment, the aforementioned cylinder gripper is connected to the slide surface of the second guide rail module via a second connecting seat.

[0015] In one embodiment, the second guide rail module described above is configured as an electric slide.

[0016] In one embodiment, the above-mentioned pipe clamping device includes a clamp and a guide wheel. The clamp is disposed on the other side of the cylinder jaw relative to the positioning element, and the clamp, cylinder jaw, and positioning element are arranged along the pipe conveying direction. The guide wheel is rotatably disposed on the adjacent side of the clamp, so that the guide wheel can guide the pipe.

[0017] In one embodiment, the aforementioned clamp is connected to drive a cylinder to obtain clamping power.

[0018] In one embodiment, the guide wheel is configured as a guide rubber wheel to achieve a rolling connection between the guide wheel and the pipe contact surface.

[0019] In one embodiment, the sawing device includes a third guide rail module, a drive assembly, and a saw blade. The third guide rail module extends perpendicularly to the pipe conveying direction and is disposed between the cylinder gripper and the clamp. The drive assembly and the saw blade are connected to the slide surface of the third guide rail module. The saw blade is connected to the output end of the drive assembly.

[0020] In one embodiment, the drive assembly includes a drive motor and a transmission belt. The drive motor is mounted on the slide surface of the third guide rail module, and the output end of the drive motor is connected to the saw blade via the transmission belt.

[0021] In one embodiment, the above-mentioned discharge device includes a conveyor belt and a storage structure. The conveyor belt is disposed on the bottom side of the traction device, the pipe clamping device, the positioning device and the sawing device; the storage structure is disposed on the bottom side of the conveyor belt.

[0022] In one embodiment, the aforementioned fully automatic CNC pipe cutting machine further includes a dust extraction and slag removal device, which is located at the bottom of the housing and on the bottom side of the storage structure.

[0023] In one embodiment, the aforementioned fully automatic CNC pipe cutting machine further includes a human-machine interface, which is disposed on the surface of the housing.

[0024] The aforementioned fully automatic CNC pipe cutting machine uses a first guide rail module to drive the positioning structure to move precisely along a preset path. It can directly and digitally set the length of each cut, eliminating visual and operational errors caused by manual line drawing and tool setting. This ensures that each cut pipe section has a highly consistent length, resulting in stable and reliable product quality. The automated cycle of traction device clamping and conveying → positioning device and pipe clamping device working together for positioning and clamping → sawing device descending and cutting → cut pipe output via discharge device can be performed continuously and at a stable pace, significantly shortening the processing time per unit and increasing production efficiency by orders of magnitude compared to traditional manual operation. The system improves efficiency and, during the sawing process, the pipe is simultaneously fixed by the positioning device and the clamping device, forming a stable "two-end support" structure. This effectively suppresses the vibration and deformation of the pipe under the impact of the saw blade, resulting in a smoother, burr-free cut surface. It also prevents the saw blade from getting stuck or damaged due to pipe movement, extends the service life of the saw blade, and reduces cutting noise. Furthermore, the cut pipe falls directly onto the discharge device below under gravity and is immediately and automatically conveyed out, seamlessly connecting the "processing" and "collection" stages. This avoids the accumulation of workpieces in the processing area and eliminates the need for manual workpiece retrieval inside the equipment. Attached Figure Description

[0032] Please refer to Figures 1 and 2. This invention discloses a fully automatic CNC pipe cutting machine 1. The fully automatic CNC pipe cutting machine 1 includes a housing 10, a traction device 20, a pipe clamping device 30, a positioning device 40, a sawing device 50, and a discharge device 60. The traction device 20, pipe clamping device 30, positioning device 40, sawing device 50, and discharge device 60 are all installed inside the housing 10. Specifically, a working cavity a is provided inside the housing 10, and the working cavity a is located at the top of the housing 10, forming an installation and processing space with a certain volume. The discharge device 60 is installed at the bottom of the working cavity a. The positioning device 40, traction device 20, and pipe clamping device 30 are located on the top side of the discharge device 60, and the clamping device, traction device 20, and positioning device 40 are arranged sequentially from one end of the working cavity a to the other end. The pipe to be cut is sequentially conveyed to the positioning device 40 via the clamping device and the traction device 20. During this process, the traction device 20 clamps the side surface of the pipe and pulls it toward one end of the positioning device 40. When the pipe is in place, the positioning device 40 positions the front end of the pipe, while the clamping device 30, in conjunction with the positioning device 40, clamps the rear end of the pipe, thereby achieving the positioning and clamping of the pipe. The sawing device 50 is movably arranged in the top space between the traction device 20 and the clamping device 30. When the traction device 20 pulls the pipe into place, the positioning device 40, in conjunction with the clamping device 30, completes the positioning and clamping of the pipe. Then, the sawing device 50 descends and saws the pipe to obtain the target length of pipe. The pipe falls into the discharge device 60 on the bottom side for discharge, thus completing the pipe cutting process of the fully automatic CNC pipe cutting machine 1. More specifically, the positioning device 40 includes a first guide rail module 41 and a positioning structure 42. The first guide rail module 41 extends along the conveying direction of the pipe. The positioning structure 42 is installed on the movable end surface of the first guide rail module 41 corresponding to the conveying path of the pipe, so that the first guide rail module 41 can drive the positioning structure 42 to reciprocate along the conveying path of the pipe. Then, according to the target length of the pipe, the positioning structure 42 moves relative to the pipe clamping device 30 to a preset position and cooperates with the front end of the pipe, thereby limiting the cutting position of the pipe and achieving the purpose of fixed-length cutting of the pipe.Based on the above settings, the fully automatic CNC pipe cutting machine 1 of this solution drives the positioning structure 42 to move precisely on a preset path through the first guide rail module 41. It can directly and digitally set the length of each cut, thereby eliminating visual and operational errors caused by manual drawing and tool setting. This ensures that the length of each cut pipe segment is highly consistent, resulting in stable and reliable product quality. The automated cycle of traction device 20 clamping and conveying → positioning device 40 and pipe clamping device 30 coordinating positioning and clamping → sawing device 50 descending and cutting → cut pipe output through discharge device 60 can be performed continuously with a stable rhythm, greatly shortening the processing time of a single product and significantly increasing production efficiency compared to traditional methods. The manual operation is improved by orders of magnitude; and at the moment of sawing, the pipe is simultaneously fixed by the positioning device 40 and the pipe clamping device 30, forming a stable "two-end support" structure. This effectively suppresses the vibration and deformation of the pipe under the impact of the saw blade, thereby obtaining a smoother, burr-free cut surface, preventing the saw blade from getting stuck or damaged due to the shaking of the pipe, extending the service life of the saw blade, and reducing cutting noise. In addition, the cut pipe falls directly onto the discharge device 60 below under the action of gravity and is immediately and automatically conveyed out, so that the "processing" and "collection" links are seamlessly connected, avoiding the accumulation of workpieces in the processing area and eliminating the need for manual workpiece retrieval inside the equipment.

[0033] Furthermore, the positioning structure 42 includes a first connecting seat 421 and a positioning member 422. The first connecting seat 421 is connected to the movable end surface of the first guide rail module 41. One end of the positioning member 422 is hinged to the side surface of the first connecting seat 421 facing away from the first guide rail module 41, and the other end of the positioning member 422 extends a predetermined distance away, so that the positioning member 422 can be correspondingly set with the traction end of the traction device 20 and the clamping end of the pipe clamping device 30, thereby ensuring the fit between the positioning member 422 and the traction device 20 and the pipe clamping device 30, and thus improving the positioning accuracy of the pipe. Specifically, in one embodiment, the end of the positioning member 422 facing away from the first connecting seat 421 is set as a sleeve positioning structure 42 that corresponds to the end of the pipe, thereby ensuring the stability of the fit of the positioning member 422 in the pipe positioning process. Specifically, in another embodiment, the first guide rail module 41 is set as an electric slide, thereby driving the positioning structure 42 to reciprocate along a predetermined direction.

[0034] Furthermore, the traction device 20 includes a second guide rail module 21 and a cylinder gripper 22. The second guide rail module 21 extends along a preset pipe conveying direction and is positioned on the top side of the first guide rail module 41. The cylinder gripper 22 is connected to the movable end surface of the second guide rail module 21 to clamp and traction the incoming pipe material. Thus, the second guide rail module 21 can drive the cylinder gripper 22 to reciprocate between the positioning member 422 and the pipe clamping device 30, thereby traction the incoming pipe material to the positioning member 422 to complete the positioning process. Specifically, in one embodiment, the cylinder gripper 22 is connected to the slide surface of the second guide rail module 21 via a second connecting seat 23 to ensure the connection stability between the cylinder gripper 22 and the second guide rail module 21. Specifically, in another embodiment, the second guide rail module 21 is configured as an electric slide.

[0035] Furthermore, the pipe clamping device 30 includes a clamp 31 and a guide wheel 32. The clamp 31 is disposed on the other side of the cylinder jaw 22 relative to the positioning member 422, and the clamp 31, cylinder jaw 22, and positioning member 422 are arranged along the pipe conveying direction. The guide wheel 32 is rotatably disposed on the adjacent side of the clamp 31, thereby guiding the pipe. While ensuring stable pipe conveying, the guide wheel 32, in conjunction with the traction device 20, limits the pipe conveying path. When the pipe groove is conveyed into place and the positioning member 422 completes its positioning, the clamp 31 clamps the side surface of the pipe. Specifically, in one embodiment, the clamp 31 is connected to a drive cylinder (not shown) to obtain clamping power. Specifically, in another embodiment, the guide wheel 32 is configured as a guide rubber wheel to achieve rolling connection between the guide wheel 32 and the pipe contact surface. Furthermore, the guide wheel 32, through connection to a suitable motor (not shown), can cooperate with the traction device 20 to drive the pipe.

[0036] Furthermore, the sawing device 50 includes a third guide rail module 51, a drive assembly 52, and a saw blade 53. The third guide rail module 51 extends perpendicularly to the pipe conveying direction and is disposed between the cylinder gripper 22 and the clamp 31. The drive assembly 52 and the saw blade 53 are connected to the slide surface of the third guide rail module 51. The saw blade 53 is connected to the output end of the drive assembly 52. ​​Thus, the third guide rail module 51 can cause the drive assembly 52 to reciprocate up and down relative to the pipe. During this process, the drive assembly 52 can drive the saw blade 53 to rotate. Thus, the saw blade 53 completes the cutting of the pipe at a preset cutting angle during the descent and then rises to reset. Specifically, in one embodiment, the drive assembly 52 includes a drive motor 521 and a transmission belt 522. The drive motor 521 is mounted on the slide surface of the third guide rail module 51, and the output end of the drive motor 521 is connected to the saw blade 53 through the transmission belt 522, thereby realizing the power input of the saw blade 53.

[0037] Furthermore, the discharge device 60 includes a conveyor belt 61 and a storage structure 62. The conveyor belt 61 is located on the bottom side of the traction device 20, the pipe clamping device 30, the positioning device 40, and the sawing device 50; the storage structure 62 is located on the bottom side of the conveyor belt 61. Thus, after the pipe is cut, the positioning member 422 disengages from the end of the pipe, the cylinder gripper 22 releases the pipe, and the pipe of the preset length falls into the conveyor belt 61. The conveyor belt 61 transports the pipe to the storage structure 62, thereby completing the discharge process.

[0038] Furthermore, the fully automatic CNC pipe cutting machine 1 also includes a dust collection and slag removal device 70, which is located at the bottom of the housing 10 and on the bottom side of the storage structure 62, to collect the dust and slag generated during the cutting process, so as to ensure the cleanliness of the production environment.

[0039] Furthermore, the fully automatic CNC pipe cutting machine 1 also includes a human-machine interface 80, which is set on the surface of the housing 10 to facilitate the operator's operation control, program calling and parameter input of the fully automatic CNC pipe cutting machine 1.

[0040] In summary, the fully automatic CNC pipe cutting machine disclosed in this invention drives the positioning structure to move precisely along a preset path via the first guide rail module. It can directly and digitally set the length of each cut, thereby eliminating visual and operational errors caused by manual line drawing and tool setting. This ensures that the length of each cut pipe segment is highly consistent, resulting in stable and reliable product quality. The automated cycle of traction device clamping and conveying → positioning device and pipe clamping device working together for positioning and clamping → sawing device descending and cutting → cut pipe output via discharge device can be performed continuously and at a stable pace, greatly shortening the processing time of a single product and significantly increasing production efficiency compared to traditional manual operation. This results in an order-of-magnitude improvement. Furthermore, during the sawing process, the pipe is simultaneously fixed by the positioning device and the clamping device, forming a stable "two-end support" structure. This effectively suppresses the vibration and deformation of the pipe under the impact of the saw blade, thereby obtaining a smoother, burr-free cut surface, preventing the saw blade from getting stuck or damaged due to pipe shaking, extending the service life of the saw blade, and reducing cutting noise. In addition, the cut pipe falls directly onto the discharge device below under the action of gravity and is immediately and automatically conveyed out, making the "processing" and "collection" stages seamlessly connected, avoiding the accumulation of workpieces in the processing area, and eliminating the need for manual workpiece retrieval inside the equipment.

[0041] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0042] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
