Technical Field

[0001] This invention relates to a plastic pipe cutting device, and more particularly to a high-precision pipe cutting device that can adjust the cutting environment according to environmental changes to achieve high-precision cutting. Background Technology

[0002] Plastic pipe cutting devices use mechanical or electric drives to cut tools (such as blades or saw blades) to cut plastic pipes. Existing cutting devices cut pipes to the appropriate length, and common cutting methods include manual cutting and cutting with a pipe cutting machine. Regardless of whether it's manual or machine cutting, the pipe is measured first, and then cut using tools like pipe cutters. This method has precision limitations; it cannot adapt cutting parameters to different pipe materials and environmental parameters, resulting in insufficient mechanical precision at the cut end of different pipes, leading to uneven cross-sections, cut deformation, and cracking. Summary of the Invention

[0003] This invention provides a high-precision pipe cutting device to solve the aforementioned technical problems, specifically adopting the following technical solution:

[0004] A high-precision pipe cutting device includes: a fixed clamping plate; a first bracket for supporting one end of a pipe fixedly disposed on one side of the fixed clamping plate; a slide rod fixedly disposed on the fixed clamping plate, the slide rod having a scale; a cutting clamping plate movably disposed on the slide rod; the fixed clamping plate having a first through hole for the pipe to pass through; the cutting clamping plate having a second through hole horizontally aligned with the first through hole, and a second bracket for supporting the other end of the pipe fixedly disposed on the side of the second through hole facing the fixed clamping plate; a limiting member for limiting the position of the end of the pipe disposed in the first through hole; a cutting assembly disposed within a cavity structure formed by the cutting clamping plate; the cutting assembly including: a rotating cutting blade and a cutting motor for driving the cutting blade; a humidity sensor for detecting the humidity within the cavity and a temperature sensor for detecting the temperature within the cavity disposed within the cavity; a humidity regulating structure for regulating the humidity within the cavity and a temperature regulating structure for regulating the temperature within the cavity. The temperature control structure is configured to regulate the temperature of the pipe fittings. A controller for controlling the operation of the aforementioned electrical components is installed within the cavity of the fixed clamp. The cutting motor, humidity sensor, temperature sensor, humidity control structure, and temperature control structure are all communicatively connected to the controller. The controller adjusts the cutting parameters for the corresponding pipe fittings based on the detection values ​​from the humidity and temperature sensors. The controller has a data storage unit and a data processing unit. The data storage unit stores optimal cutting parameters for various pipe fitting materials, namely, optimal temperature parameters, optimal humidity parameters, and optimal cutting speed. The controller controls the humidity control structure to adjust the humidity based on the detection values ​​from the humidity sensor until the optimal humidity parameters are reached. The controller controls the temperature control structure to adjust the temperature based on the detection values ​​from the temperature sensor until the optimal humidity parameters are reached. When the cavity has optimal humidity and optimal temperature, the controller controls the cutting blade to cut the corresponding pipe fitting at the optimal cutting speed.

[0005] Furthermore, when either the temperature or humidity inside the cavity deviates from the optimal cutting parameter by an increase, or both deviate from the optimal cutting parameter by an increase simultaneously, the controller controls the cutting blade's rotation speed to increase accordingly; when either the temperature or humidity inside the cavity deviates from the optimal cutting parameter by a decrease, or both deviate from the optimal cutting parameter by a decrease simultaneously, the controller controls the cutting blade's rotation speed to decrease accordingly.

[0006] Furthermore, the formulas used by the controller to calculate the optimal temperature and humidity parameters are as follows:

[0007] T 目标 =T 基准 +k1*(T 环境 -T 基准 )

[0008] H 目标 =H 基准 +k2*(H 环境 -H 基准 )

[0009] Among them, T 目标 and H 目标 The target temperature and humidity are T, respectively. 基准 and H 基准 These are the reference temperature and humidity for the plastic pipe fitting material, T 环境 and H 环境 Here, k1 and k2 represent the current ambient temperature and humidity, respectively, and k1 and k2 are adjustment coefficients.

[0010] Furthermore, the controller generates a first cutting speed curve based on different temperature values ​​and the corresponding hardness value of the pipe at those temperatures; the controller generates a second cutting speed curve based on different humidity values ​​and the corresponding hardness value of the pipe at those humidity values; when the temperature and humidity inside the cavity increase or decrease, the controller calculates the average speed value of the sum of the cutting speed value corresponding to the temperature value of the current node and the cutting speed value corresponding to the humidity value of the current node, and controls the cutting blade to cut at the average speed value.

[0011] Furthermore, a guide plate is fixed to the lower end of the fixed clamping plate; a screw and a drive motor for driving the screw to rotate are rotatably mounted on the guide plate; the two sides of the cutting clamping plate are threaded onto the outer circumference of the screw.

[0012] Furthermore, a conductive element is provided in the sleeve hole of the cutting clamp that is fitted around the outer periphery of the slide rod; the conductive element is electrically connected to a signal transmitter; the scale lines are conductive wires that can conduct the conductive element; the controller is communicatively connected to the signal transmitter to confirm the measured length of the pipe fitting based on the number of signal transmissions from the signal transmitter.

[0013] Furthermore, the hollow structure formed by the cutting clamp contains two sets of cutting components; the two cutting blades are positioned opposite each other on both sides of the pipe fitting inserted into the second through hole, and move in an arc around the circumference of the pipe fitting.

[0014] Furthermore, the fixed clamp is equipped with a length measuring instrument for detecting the length of the pipe fitting passing through the first through hole; the limiting member is slidably inserted into the fixed clamp to slide open or slide close the first through hole; the first bracket and the second bracket are equipped with clamping members for limiting the cutting position of the pipe fitting.

[0015] Furthermore, a circular guide rail is formed on the cutting clamp; a matching arc-shaped tooth condition is provided inside the circular guide rail; the arc-shaped tooth condition is rotatably disposed within the circular guide rail; one side of the cutting clamp has a gear on the guide plate for meshing with the external teeth of the arc-shaped tooth condition and a motor for driving the gear; two cutting components are respectively installed at both ends of the arc-shaped tooth condition and are arranged opposite each other about the pipe fitting axis; mounting cavities are formed at both ends of the arc-shaped tooth condition; the cutting motor is slidably disposed in the mounting cavity along the cavity wall; a cylinder for connecting to the cutting motor to adjust the radial position of the cutting blade relative to the second through hole is provided in the mounting cavity; a pressure sensor is provided between the extension end of the cylinder and the cutting motor; the controller controls the extension and retraction of the cylinder according to the detection value of the pressure sensor so that when cutting the corresponding pipe fitting, the cutting blade and the pipe fitting always maintain a preset cutting pressure.

[0016] Furthermore, the lower end of the cutting clamp is open, and a dust collection box is detachably installed at the opening; the integrated box is connected to a device equipped with a negative pressure device.

[0017] The advantage of this invention is that the high-precision pipe cutting device can adjust environmental parameters according to the characteristics of different pipe materials, thereby adjusting the cutting parameters according to the adaptability of different pipes. This ensures high mechanical precision of the cutting end face when cutting different pipes. Cutting is performed under highly adaptable cutting parameter conditions, making the cross-section of different pipes flat enough and the cut not easily deformed or cracked, thus achieving high-precision cutting for different pipes.

[0020] Figure 2 yes Figure 1 An enlarged schematic diagram of a portion of the high-precision pipe cutting device.

[0021] A high-precision pipe cutting device 10 includes a fixed clamping plate 11, a first through hole 111, a first bracket 12, a slide rod 13, a cutting clamping plate 14, a second through hole 141, a circular guide rail 142, a cutting motor 15, a humidity sensor 16, a temperature sensor 17, a humidity regulating structure 18, a temperature regulating structure 19, a controller 20, a guide plate 21, a screw 22, a drive motor 23, a cylinder 24, a clamping component 25, a motor 26, a dust collection box 27, a negative pressure device 28, a limiting component 29, a second bracket 30, a cutting blade 31, a length measuring instrument 32, a circular arc tooth conditioner 33, a mounting cavity 331, a gear 34, and a signal transmitter 35. Detailed Implementation

[0022] Embodiments of the present invention are described in detail below. Examples of these embodiments are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0023] like Figures 1 to 2 The diagram illustrates a high-precision pipe cutting device 10 according to this application. It includes: a fixed clamping plate 11, with a first bracket 12 fixedly mounted on one side of the fixed clamping plate 11, supporting one end of a pipe fitting. A sliding rod 13 is fixedly mounted on the fixed clamping plate 11, with a scale 131 on the sliding rod 13. A cutting clamping plate 14 is also movably mounted on the sliding rod 13. By sliding the cutting clamping plate 14 along the sliding rod 13 to adjust its position corresponding to the scale 131, the distance between the cutting clamping plate 14 and the fixed clamping plate 11 is adjusted, thus the distance between the two clamping plates is the length of the pipe fitting to be cut. The fixed clamping plate 11 has a first through hole 111 for the pipe fitting to pass through, and the cutting clamping plate 14 has a second through hole 141 horizontally aligned with the first through hole 111. A second bracket 30 is fixedly mounted on the side of the second through hole 141 facing the fixed clamping plate 11 to support the other end of the pipe fitting. A limiting member is provided within the first through hole 111 to limit the position of the pipe fitting end. When it is necessary to cut the pipe fitting, one end of the pipe fitting is passed through the second through hole 141 until it is inserted into the first through hole 111. The limiting plate limits the end of the pipe fitting. Then, the cutting clamp 14 is slid to the specified scale 131 position, and the cutting length of the pipe fitting can be measured.

[0024] Furthermore, the cutting clamp 14 has a cavity structure, and a cutting assembly is provided inside the cavity structure. The cutting assembly includes a cutting blade 31 and a cutting motor 15. The cutting blade 31 is rotatably mounted on the drive end of the cutting motor 15. When the cutting motor 15 is started, it drives the cutting blade 31 to rotate so as to cut the pipe.

[0025] Furthermore, a temperature sensor 17 and a humidity sensor 16 are installed inside the cavity. The humidity sensor 16 detects the humidity inside the cavity, and the temperature sensor 17 detects the temperature inside the cavity. A humidity regulating structure 18 and a temperature regulating structure 19 are also installed inside the cavity. The humidity regulating structure 18 regulates the humidity inside the cavity, and the temperature regulating structure 19 regulates the temperature inside the cavity. A controller 20 is installed inside the fixed clamping plate 11 to control the operation of the aforementioned electrical components. The cutting motor 15, humidity sensor 16, temperature sensor 17, humidity regulating structure 18, and temperature regulating structure 19 are all communicatively connected to the controller 20. Then, the controller 20 adjusts the cutting parameters for the corresponding pipe fitting based on the detection values ​​of the humidity sensor 16 and the temperature sensor 17. Specifically:

[0026] The controller 20 is equipped with a data storage unit and a data processing unit. The data storage unit stores optimal cutting parameters for various pipe fitting material types, namely optimal temperature parameters, optimal humidity parameters, and optimal cutting speed. During pipe cutting, the corresponding material type is input. The controller 20, based on the optimal cutting parameters stored in the data storage unit, controls the humidity adjustment structure 18 to adjust the humidity according to the detection value of the humidity sensor 16 until the optimal humidity parameter is reached. The controller 20 also controls the temperature adjustment structure 19 to adjust the temperature according to the detection value of the temperature sensor 17 until the optimal humidity parameter is reached. Finally, when the cavity has optimal humidity and optimal temperature, the controller 20 controls the cutting motor 15 to start with the optimal cutting parameters, thereby controlling the cutting blade 31 to cut the corresponding pipe fitting at the optimal cutting speed.

[0027] Through the above-described technical solution, the high-precision pipe cutting device 10 provided by the application can adjust environmental parameters according to the characteristics of different pipe materials, thereby adjusting the cutting parameters according to the adaptability of different pipes. This ensures high mechanical precision of the cutting end face when cutting different pipes. Cutting under highly adaptable cutting parameter conditions results in a smooth cross-section for different pipes, and the cut is less prone to deformation and cracking, thus achieving high-precision cutting for different pipes. In other words, this device can not only adopt the optimal cutting parameters based on the material characteristics of the pipe itself to improve the cutting accuracy of the pipe and reduce the probability of burrs, deformation, and gaps on the cutting surface, but also reduce energy consumption and avoid continuously using high-power cutting to maximize cutting force.

[0028] In one specific implementation, when either the temperature or humidity within the cavity deviates significantly from the optimal cutting parameters, or both deviate significantly from the optimal cutting parameters simultaneously, the controller 20 controls the cutting blade 31 to increase its rotational speed. In other words, this device is suitable for pipe materials that are generally plastic. The hardness of plastic pipes changes with environmental factors (humidity, temperature). When either humidity or temperature is excessive, or both are excessive, the hardness of the pipe decreases. This decrease in hardness increases the adaptability of the cutting speed, thus reducing the likelihood of burrs, unevenness, and deformation at the pipe cut. Conversely, when either the temperature or humidity within the cavity deviates significantly from the optimal cutting parameters, or both deviate significantly from the optimal cutting parameters simultaneously, the controller 20 controls the cutting blade 31 to decrease its rotational speed. In other words, this device is generally suitable for pipe materials made of plastic. The hardness of plastic pipes changes with environmental factors (humidity and temperature). When either humidity or temperature is low, or both are low, the hardness of the pipe increases. Increased hardness reduces the adaptability of the cutting speed, thus decreasing the likelihood of cracking or deformation due to excessive impact force at the cut edge. Therefore, this solution adjusts the cutting speed according to the softening or hardening of the corresponding pipe material. This ensures cutting accuracy while achieving effective energy saving, reducing dust and burrs, and improving the cutting quality of the pipe.

[0029] Specifically, the formulas used by controller 20 to calculate the optimal temperature and humidity parameters are as follows:

[0030] T 目标 =T 基准 +k1*(T 环境 -T 基准 )

[0031] H 目标 =H 基准 +k2*(H 环境 -H 基准 )

[0032] Among them, T 目标 and H 目标 The target temperature and humidity are T, respectively. 基准 and H 基准 These are the reference temperature and humidity for the plastic pipe fitting material, T 环境 and H 环境 These represent the current ambient temperature and humidity, respectively, with k1 and k2 being adjustment coefficients.

[0033] Furthermore, the data processing unit of controller 20 generates a first cutting speed curve based on different temperature values ​​and the corresponding hardness values ​​of the pipe material at those temperatures, and a second cutting speed curve based on different humidity values ​​and the corresponding hardness values ​​of the pipe material at those humidity values. In this way, the optimal cutting speeds corresponding to different temperatures and humidity levels are stored graphically in the data storage unit for easy reference. When the temperature and humidity inside the cavity increase or decrease due to sudden changes in the environment, controller 20 calculates the average speed value of the sum of the cutting speed values ​​corresponding to the current node's temperature value and the current node's humidity value, and controls the cutting blade 31 to cut at the average speed value, thereby ensuring timely and precise cutting with the most accurate cutting parameters. This cutting state is real-time and dynamic, with cutting parameters changing with the real-time changes in the environment, resulting in higher cutting accuracy.

[0034] The humidity control structure in the above scheme can be an atomizer, and the temperature control structure can be a resistance heater. Both the atomizer and the resistance heater are existing structures and can be directly installed and used.

[0035] In one specific implementation, a guide plate 21 is fixed to the lower end of the fixed clamping plate 11. A screw 22 and a drive motor 23 are rotatably mounted on the guide plate 21. The two sides of the cutting clamping plate 14 are threaded onto the outer periphery of the screw 22. The drive motor 23 drives the screw 22 to rotate, thereby driving the cutting clamping plate 14 to automatically adjust its position, and then automatically measuring the cutting position of the pipe according to the actual cutting length of the pipe.

[0036] Furthermore, the cutting clamp 14 is fitted onto the outer periphery of the slide rod 13 through a sleeve hole, and a conductive element is provided inside the sleeve hole. The conductive element is electrically connected to a signal transmitter 35. The scale lines of the scale 131 are conductive wires that can conduct the conductive element. The controller is communicatively connected to the signal transmitter 35 to determine the measured length of the pipe fitting based on the number of signal transmissions and the time intervals of the signal transmitter 35. That is, in the initial state of cutting, the cutting clamp 14 is in the initial position. When the position of the cutting clamp 14 needs to be adjusted, the drive motor 23 drives the screw 22 to rotate, thereby driving the cutting clamp 14 to automatically adjust its position. The conductive element conducts once each time it passes a conductive wire, and at this time, it sends an electrical signal to the controller 20. When the number of electrical signals received by the controller 20 reaches the preset number, the controller 20 controls the drive motor 23 to stop running. The measured length of the pipe fitting at this time is the length to be cut. In this way, not only can the cutting position be automatically adjusted, but the cutting length of the pipe fitting can also be accurately measured, which can meet the application scenarios with high accuracy in pipe cutting length and cutting surface.

[0037] In one specific implementation, the hollow structure of the cutting clamp 14 contains two sets of cutting components. Two cutting blades 31 are positioned opposite each other on both sides of the pipe fitting inserted into the second through hole 141, and move in an arc around the circumference of the pipe fitting. In this way, the relative pressing force of the two cutting blades 31 can ensure that the cutting pressure on both sides of the pipe fitting is balanced. Then, the arc-shaped movement of the two cutting blades 31 can prevent the cutting pressure from deforming the cut end of the pipe fitting.

[0038] The arc-shaped movement of the cutting blade 31 described above can be achieved by driving the cutting assembly to move in an arc shape via a connecting rod and a guide rail. Alternatively, the arc-shaped movement of the cutting blade 31 can be achieved by setting an arc-shaped rack inside the guide rail, and then driving the arc-shaped rack to rotate around the axis of the pipe within the guide rail via a gear.

[0039] As a specific embodiment of this application, a circular guide rail 142 is formed on the cutting clamp, and a matching arc-shaped tooth condition 33 is provided inside the circular guide rail 142. The arc-shaped tooth condition 33 is rotatably disposed within the circular guide rail 142. A gear 34 and a motor 26 are provided on one side of the cutting clamp 14. The motor 26 drives the gear 34, thereby causing the arc-shaped tooth condition 33 to rotate around the central axis of the second through hole 141. Two cutting components are respectively installed at both ends of the arc-shaped tooth condition 33 and are arranged opposite to each other about the central axis of the second through hole 141. Mounting cavities are formed at both ends of the arc-shaped tooth condition 33. The cutting motor 15 is slidably disposed in the mounting cavity along the cavity wall, thereby ensuring the cutting stability of the cutting components. The cutting components can adjust the cutting position along the radial direction of the arc-shaped tooth condition 33 to adapt to pipes with different wall thicknesses. Specifically, the relative distance between the two cutting blades 31 can be adjusted by extending and retracting the cylinder 24. A pressure sensor is installed between the telescopic end of the cylinder 24 and the cutting motor 15. The controller 20 controls the extension and retraction of the cylinder based on the detection value of the pressure sensor to maintain a preset cutting pressure when cutting the corresponding pipe fitting. Different pipe fittings have different cutting pressure values, which can be stored in the storage unit of the controller 20. Thus, when cutting pipe fittings of different materials, the controller controls the cylinder to apply pressure to the cutting motor according to the corresponding pressure value.

[0040] Specifically, the outer periphery of the arc-shaped tooth condition 33 is provided with an arc-shaped T-shaped protrusion, and the inner periphery of the circular guide rail 142 is formed with an annular T-shaped groove. The arc-shaped tooth condition 33 is stably rotatably mounted within the circular guide rail 142 through the cooperation of the T-shaped protrusion and the T-shaped groove. Multiple ball bearings are also provided between the T-shaped protrusion and the T-shaped groove to reduce the rotational friction between the T-shaped protrusion and the T-shaped groove.

[0041] In one specific implementation, the fixed clamping plate 11 is equipped with a length measuring instrument 32, which is used to detect the length of the pipe fitting passing through the first through hole 111. Therefore, when cutting a long pipe fitting, if the long pipe fitting exceeds the value range of the scale 131 on the slide rod 13, the length exceeding the first through hole 111 can be measured by the length measuring instrument 32. This allows for the measurement and cutting of various long pipe fittings. The first bracket 12 and the second bracket 30 are equipped with clamping members 25 for limiting the pipe fitting, thereby ensuring the stability of the pipe fitting's cutting position. In this solution, the limiting member 29 is slidably inserted into the fixed clamping plate 11 to slide open or slide close the first through hole 111. When cutting a long pipe fitting, it slides out of the first through hole 111; when cutting a short pipe fitting, it inserts into the first through hole 111 to directly block the first through hole 111, limiting the end of the pipe fitting. After the limiting member 29 is pulled upward out of the first through hole 111, its position is limited by its own limiting pin.

[0042] In one specific implementation, an air knife assembly 26 is provided on one side of the first through hole 111. The air knife assembly 26 can be used to remove burrs and dust from the cut surface of the pipe fitting. The air knife assembly 26 includes a first air knife ring 261 and a second air knife ring 262. The first air knife ring 261 is used to clean the inner circumference of the end face of the pipe fitting cut, and the second air knife ring 262 is used to clean the outer circumference of the end face of the pipe fitting cut. After the pipe fitting is cut, it can be pulled outward along the first through hole 111, thereby cleaning burrs and dust from the inner and outer edges of the cut end face of the pipe fitting. Generally, air knife cleaning is performed after cutting to avoid the high-pressure airflow affecting the cutting accuracy.

[0043] Furthermore, the lower end of the cutting clamp 14 is designed to be open, and a dust collection box 27 is detachably installed at the opening. The integrated box is connected to a negative pressure device 28, which collects and sucks up the cutting dust inside the cutting cavity. Generally, dust collection is performed after cutting to avoid the negative pressure airflow affecting the cutting accuracy.

[0044] When cutting short pipe fittings, the pipe fittings are first inserted into the second through hole 141 and the first through hole 111 in sequence. Then, the position of the pipe fitting is limited by the limiting member 29 inserted into the first through hole 111. At this time, the clamping member 25 clamps both ends of the pipe fitting under the drive of the cylinder. Next, the drive motor 23 drives the screw 21 to move the cutting clamp to the preset cutting position. The controller controls the temperature adjustment structure 19 and the humidity adjustment structure 18 according to the detection data of the temperature sensor 17 and the humidity sensor 16 to adjust the temperature and humidity inside the cavity of the cutting clamp 14 to the target value. Then, the controller controls the cutting blade 31 to cut with the optimal cutting parameters. During this process, if the ambient temperature or humidity suddenly changes, the controller controls the cutting blade to adjust the cutting speed in real time according to the changed temperature and humidity values. During the cutting process, the gear 34 drives the arc gear condition 33 to rotate, thereby driving the two cutting blades 31 to also make circular motion. This not only improves the cutting efficiency but also improves the cutting accuracy.

[0045] When cutting long pipe fittings, the cutting operation process is the same as that for short pipe fittings. The only difference is that when inserting the pipe fitting at the beginning, the first through hole 111 is opened, and then the pipe fitting is passed through the first through hole 111. The length of the pipe fitting passing through the first through hole 111 can be measured by the length measuring instrument 32. When the length measuring instrument 32 detects that the length of the pipe fitting end protruding reaches the preset length, it sends a signal to the controller 20. The controller 20 controls the cylinder to drive the clamping part 25 to clamp the pipe fitting. Then, the same operation as the cutting process for short pipe fittings is used to cut the pipe fitting.

[0046] Based on this technical solution, the corresponding clamping member and the first bracket, as well as the corresponding clamping member and the second bracket, can all be designed as arc-shaped. The corresponding clamping member and the first bracket can move relative to each other, and the corresponding clamping member and the second bracket can also move relative to each other. This allows for the cutting of pipes of different diameters through the relative movement of the corresponding clamping member and the first bracket, and the relative movement of the corresponding clamping member and the second bracket. When inserting pipes of different diameters, the pipes are clamped by the relative movement of the corresponding clamping member and the first bracket, and the relative movement of the corresponding clamping member and the second bracket, ensuring that the central axes of the pipes and the first and second through holes coincide. The relative movement of the corresponding clamping member and the first bracket, and the relative movement of the corresponding clamping member and the second bracket, can be controlled by the limited stroke extension and retraction of a cylinder, thereby ensuring that the central axes of the pipes and the first and second through holes coincide. Furthermore, the cutting blade can be replaced to adapt to different types of pipes.

[0047] In existing technologies, cutting devices cut pipes to appropriate lengths. Common cutting methods include manual cutting or using pipe cutting machines. Regardless of the method, the pipe is measured before cutting with tools like pipe cutters. This approach suffers from precision deficiencies, failing to adapt cutting parameters to different pipe materials and environmental conditions. Consequently, the mechanical precision of the cut end face is insufficient for different pipes, leading to uneven cross-sections, cut deformation, and cracking. The technical solution described in this application solves these problems, effectively improving cutting precision, saving energy, and increasing production efficiency. It is suitable for applications requiring high pipe cutting precision. Therefore, using the high-precision pipe cutting device of this application can significantly improve the economic efficiency of the production line.

[0048] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the above embodiments do not limit the present invention in any way, and all technical solutions obtained by equivalent substitution or equivalent transformation fall within the protection scope of the present invention.
