Description

Technical Field

[0001] This utility model relates to the field of pipe cutting machines, and in particular to an automatic pipe cutting machine. Background Technology

[0002] In the pipe processing industry, traditional pipe cutting methods rely on manual operation, such as using manual saws or simple cutting equipment. However, this method has several drawbacks: 1. Cutting accuracy: It is greatly affected by human factors, such as the operator's skill level, individual differences in the state of operation, and the difficulty in ensuring the consistency of each action in manual operation, which makes the cutting accuracy unstable and difficult to meet the requirements of high-precision pipe processing. 2. Cutting efficiency: Manual operation has limited speed. From feeding and fixing the pipe to unloading after cutting, each step is done manually, which takes a long time and cannot meet the needs of large-scale, high-efficiency production. 3. Cost aspect: High labor costs, with rising labor costs increasing the burden on enterprises; 4. Safety: During the cutting process, debris will fly around. When operating manually, the operator is close to dangerous parts such as the cutting tool. Manual operation is prone to misoperation, such as incorrect handling after the saw blade jams, which poses a significant safety hazard. Utility Model Content

[0003] To address the aforementioned problems, this utility model provides an automatic pipe cutting machine that, through the cooperation of a positioning system and a pipe conveying system, solves the problems of low precision, low efficiency, high cost, and poor safety in the existing pipe cutting process, and can achieve automation, high precision, and high efficiency in pipe cutting.

[0004] According to one aspect of the present invention, an automatic pipe cutting machine is provided, including a frame, on which a pipe conveying mechanism, a rotating mechanism, a cutting mechanism and a control system are mounted. The pipe conveying mechanism and the rotating mechanism are respectively mounted at both ends of the frame, and the cutting mechanism is located above and between the pipe conveying mechanism and the rotating mechanism. The pipe conveying mechanism includes a servo motor, a horizontally arranged transmission screw, and a pipe clamp. The servo motor is connected to the transmission screw, and the pipe clamp is mounted on the transmission screw and used to clamp the pipe. The rotating mechanism is installed at the other end of the frame. The rotating mechanism includes a rotating motor and a rotating head. The rotating motor and the rotating head are connected by a drive. The rotating head is at the same height as the drive screw and is used to install the pipe. The cutting mechanism includes a lifting mechanism, a cutting motor, and a cutting blade. The cutting motor is mounted on the lifting mechanism, and the cutting blade is connected to the bottom of the cutting motor and located above the pipe. The control system is connected to the pipe conveying mechanism, the rotating mechanism, and the cutting mechanism.

[0005] In some embodiments, an outer cover is provided above the frame, and the pipe conveying mechanism, the rotating mechanism, and the cutting mechanism are all located inside the outer cover. The advantage of this is that the outer cover creates a closed structure, reducing the splashing of cutting debris and operator contact with the cutting tools, thus lowering safety risks.

[0006] In some embodiments, the outer casing is provided with multiple door panels, and the frame is equipped with multiple door-opening gas springs, each of which can be easily connected to each of the door panels. The advantage is that each door-opening gas spring can automatically open and close the door panels.

[0007] In some embodiments, a control panel is provided on the outer casing, and the control panel is connected to the control system. The advantage of this is that the operation of each mechanism can be controlled through the control panel.

[0008] In some embodiments, the pipe clamp employs an adjustable clamping structure. Its advantage lies in its ability to accommodate pipes of different diameters and materials, ensuring pipe stability during transport.

[0009] In some embodiments, multiple pipe conveying mechanisms are arranged sequentially. This is advantageous because it enables the conveying of pipes over longer distances to meet processing needs.

[0010] In some embodiments, the rotary motor is driven to the rotary head via a transmission mechanism. The advantage is that the specific structure of the rotary mechanism is further described.

[0011] In some implementations, the control system is based on an industrial computer or programmable logic controller, coupled with a human-machine interface. Its advantage lies in describing the specific structure of the control system.

[0012] In some implementations, the control system can set the cutting length, speed, and tool parameters through the human-machine interface. Its advantage lies in further describing the functionality of the control system.

[0013] In some embodiments, a positioning photoelectric sensor is also installed on the frame, located between the pipe conveying mechanism and the rotating mechanism and facing the pipe. Its advantage is that it can monitor the pipe conveying length in real time. When the pipe is conveyed to the set length, the positioning photoelectric sensor sends a signal for precise pipe positioning, ensuring the accuracy of the cutting length.

[0016] The present invention will now be described in further detail with reference to the accompanying drawings.

[0017] like Figure 1-5 As shown, the automatic pipe cutting machine includes a frame 1, and other mechanisms, mainly including at least one pipe conveying mechanism 2, a rotating mechanism 3, a cutting mechanism 4, and a control system (not shown in the figure), are all installed on the frame 1.

[0018] An outer cover 11 is installed above the frame 1 to form a closed structure. The pipe conveying mechanism 2, the rotating mechanism 3, and the cutting mechanism 4 are all installed inside the outer cover 11, which can reduce the splashing of cutting debris and the contact between the operator and the cutting tool, thereby reducing safety risks.

[0019] Preferably, the outer cover 11 is provided with a plurality of doors 12 that can be opened, and a plurality of door opening air rods 13 are installed on the frame 1. Each door opening air rod 13 is connected to each door 12 and can automatically open and close the door 12.

[0020] Preferably, a control panel 14 is installed on the outer cover 11. The control panel 14 is connected to the control system and has structures such as rotation and display screen, which can control the operation of each mechanism.

[0021] like Figure 3 As shown, the pipe conveying mechanism 2 is installed at one end of the frame 1. The pipe conveying mechanism 2 mainly includes a servo motor 21, a horizontally arranged transmission screw 22, and a pipe clamp 23. The servo motor 21 is connected to the transmission screw 22, and the pipe clamp 23 is installed on the transmission screw 22. The pipe clamp 23 can clamp the pipe 6 being fed, and the operation of the servo motor 21 can drive the transmission screw 22, so that the pipe clamp 23 and the pipe 6 on it move along the guide rail, realizing the precise conveying of the pipe 6.

[0022] Preferably, the clamp 23 for the pipe 6 adopts an adjustable clamping structure, which can adapt to pipes 6 of different diameters and materials, ensuring the stability of the pipe 6 during transportation.

[0023] Preferably, there can be multiple pipe conveying mechanisms 2 arranged in sequence, which can convey the pipes 6 over a longer distance to meet processing needs.

[0024] like Figure 4 As shown, the rotating mechanism 3 is installed at the other end of the frame 1. The rotating mechanism 3 mainly includes a rotating motor 31, a rotating head 32, and a transmission mechanism 33. The rotating motor 31 and the rotating head 32 are connected by the transmission mechanism 33, and the rotating head 32 is at the same height as the transmission screw 22. The rotating head 32 can receive the pipe 6 transmitted by the screw 22. The operation of the rotating motor 31 can cause the rotating head 32 to rotate through the transmission mechanism 33 to cooperate with the processing.

[0025] like Figure 5 As shown, the cutting mechanism 4 is located above the pipe conveying mechanism 2 and the rotating mechanism 3 on the frame 1. The cutting mechanism 4 mainly includes a lifting mechanism 41, a cutting motor 42, and a cutting blade 42. The cutting motor 42 is mounted on the lifting mechanism 41, and the cutting blade 42 is connected to the bottom of the cutting motor 42 and located above the pipe 6. The cutting blade lifting mechanism 41 is electrically or hydraulically driven. The operation of the lifting mechanism 41 causes the cutting motor 42 to rise and fall accordingly, and the operation of the cutting motor 42 causes the cutting blade 42 to move and cut the pipe 6. Thus, the lifting and lowering of the cutting blade 42 can be precisely controlled according to the thickness of the pipe 6 and the cutting requirements, achieving fast and stable cutting.

[0026] The control system is connected to the pipe conveying mechanism 2, the rotating mechanism 3, and the cutting mechanism 4. It can coordinate and control the operation of each mechanism according to the set parameters and sensor feedback signals to realize an automated cutting process. The control system is based on an industrial computer or programmable logic controller (PLC) and is equipped with a human-machine interface (HMI). Operators can set the cutting length, speed, tool parameters, etc. through the HMI on the control system.

[0027] In addition, a positioning photoelectric sensor 5 is installed between the pipe conveying mechanism 2 and the rotating mechanism 3 on the frame 1. The positioning photoelectric sensor 5 faces the pipe 6 and can monitor the conveying length of the pipe 6 in real time. When the pipe 6 is conveyed to the set length, the positioning photoelectric sensor 5 sends a signal to accurately position the pipe 6 and ensure the cutting length accuracy.

[0028] The automatic pipe cutting machine of this utility model has the following beneficial effects: 1. High-precision cutting: With the positioning system and pipe conveying system working together, the cutting accuracy can reach ±0.5mm, meeting the processing needs of various high-precision pipes; 2. High-efficiency production: Automated operation significantly reduces manual intervention time, and the cutting speed is 3-5 times faster than traditional methods, effectively improving production efficiency and reducing production costs; 3. Enhanced safety: The fully or semi-enclosed design of the equipment reduces the splashing of cutting debris and contact between operators and the cutting tools, thus lowering safety risks; 4. High adaptability: The pipe clamps and cutting system are adjustable, which can adapt to the cutting of pipes of various diameters and materials, thus expanding the application range of the equipment.

[0029] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and all such modifications and improvements fall within the protection scope of this utility model.
