Description

Technical Field

[0001] This invention relates to the field of copper tube cutting technology, specifically a copper tube cutter for processing refrigeration components. Background Technology

[0002] In the field of refrigeration component processing, the traditional method of cutting copper pipes from the outside has many limitations, which makes the demand for cutting from the inside to the outside increasingly prominent.

[0003] On the one hand, some refrigeration components have unique structures, such as copper tube assemblies with multi-layered nesting and complex internal walls. External cutting makes it difficult to accurately cut specific parts and may damage surrounding structures. However, internal cutting allows for deep penetration into the copper tube, enabling precise severing at designated locations, meeting the processing requirements of complex components, and improving product precision and adaptability. On the other hand, external cutting results in uneven force on the cutting tool, easily generating significant vibration and noise, affecting cutting quality and accelerating tool wear. Internal cutting, on the other hand, provides relatively uniform force on the cutting tool, effectively reducing vibration and noise, extending tool life, and decreasing tool replacement frequency and costs. Furthermore, some copper tubes are prone to burrs and deformation at the ends after external cutting, requiring additional grinding and shaping processes. Internal cutting allows for better control of the cut shape during the cutting process, reducing burrs and deformation, lowering subsequent processing costs and time, and improving production efficiency. More importantly, as refrigeration equipment develops towards miniaturization and integration, the requirements for cutting precision and surface quality of copper tubes are becoming increasingly stringent. Internal cutting better meets these stringent standards, ensuring the sealing and stability of the refrigeration system and improving the overall performance and quality of the refrigeration equipment. Summary of the Invention

[0004] The purpose of this invention is to address the problems of traditional copper tube cutting equipment in the prior art, such as difficulty in achieving internal cutting of copper tubes, poor cutting accuracy, easy equipment failure caused by debris, and difficulties in maintenance. This invention proposes a copper tube cutter for processing refrigeration components. This cutter achieves precise cutting from the inside out by placing the entire structure inside the copper tube, thus meeting the processing requirements of special refrigeration components. It improves cutting accuracy and stability by utilizing an expansion sensing mechanism and an adjustable cutting mechanism. A closed debris collection mechanism and intelligent chip removal design prevent damage to the equipment from debris. Simultaneously, the optimized equipment structure facilitates the disassembly and repair of key components, reducing maintenance difficulty and costs, thereby comprehensively improving the processing quality, equipment reliability, and production efficiency of copper tube cutting.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a copper tube cutter for processing refrigeration parts, comprising a mounting sleeve, wherein an expansion sensing mechanism is provided on the outer wall of the mounting sleeve, the expansion sensing mechanism includes four transmission mounting seats, one of the transmission mounting seats is equipped with an adjustable cutting mechanism, and the other three transmission mounting seats are interconnected with a debris collection mechanism, and a rotating component is rotatably connected to the tail of the mounting sleeve.

[0006] Preferably, the expansion sensing mechanism includes a sliding sleeve, a set of rotating seats is fixedly installed on the outer wall of the sliding sleeve, a set of transmission arms is rotatably connected to the outer wall of each rotating seat, the internal rotation shaft of each transmission arm is rotatably connected to the inside of the transmission mounting seat, a set of pressure sensor mounting seats is fixedly installed inside each transmission mounting seat, and a set of pressure sensor mounting seats is rotatably connected to the inside of each set of pressure sensor mounting seats via a shaft. The characteristic feature is that the outer wall of each set of rotation pressure sensors cooperates with the pipe to be cut, enabling distance measurement and control of the expansion range of the transmission mounting seats in all directions, thereby reducing the friction force on the inner wall of the pipe during cutting.

[0007] Preferably, the adjustable cutting mechanism includes a first mounting groove, a second electric telescopic rod is fixedly installed inside the first mounting groove, a mounting plate is fixedly connected to the output end of the second electric telescopic rod, a cutting blade is fixedly installed on the outer surface of the mounting plate, a set of third limiting sliding grooves is fixedly opened on the inner wall of the first mounting groove, a dust cover is fixedly installed inside the first mounting groove by screws, a set of second limiting sliding blocks is fixedly connected to the outer surface of the mounting plate, a through hole is opened inside the dust cover, and the outer wall of the cutting blade and the inside of the through hole cooperate with each other.

[0008] Preferably, the debris collection mechanism includes a set of second mounting slots, each of which is equipped with a dust collection chamber. Each dust collection chamber is interconnected by a first connecting pipe. A retractable hose is fixedly connected to the surface flange of one of the dust collection chambers. The outer wall of the retractable hose is inserted into the interior of one of the transmission mounting seats, and one end of the retractable hose is fixedly connected to a sliding connecting seat. One end of the sliding connecting seat is fixedly connected to a second connecting pipe. One end of the second connecting pipe is fixedly connected to a collection chamber. A mesh is fixedly connected to the bottom of the collection chamber, and a miniature gate is fixedly connected to the outer wall of the collection chamber.

[0009] Preferably, a fixed rotating ring is fixedly connected to the outer surface of the mounting sleeve, a limiting rotating ring is rotatably connected to the outer wall of the fixed rotating ring, a protective sleeve is fixedly connected to the outer surface of the limiting rotating ring, an integrated pipe is connected to one end flange of the protective sleeve, a mounting disc is fixedly connected to the inside of the protective sleeve, a motor mounting base is fixedly connected to the outer surface of the mounting disc, the output end of the motor is rotatably engaged with the inside of the mounting disc, and a gear is fixedly connected to the output end of the motor, a gear ring meshes with the outer wall of the gear, and the input end of a powerful fan is fixedly connected to the output end of the motor.

[0010] Preferably, a first mounting base is fixedly connected inside the mounting sleeve, a mounting base for a first electric telescopic rod is fixedly mounted on the outer surface of the first mounting base, a set of first limiting sliding strips is fixedly connected to the outer surface of the mounting sleeve, a cross sliding seat is fixedly mounted on the outer surface of the mounting sleeve, and a second sliding limiting groove is opened inside the cross sliding seat.

[0012] Preferably, the inner wall of the second sliding limiting groove of the cross sliding seat is slidably engaged with the first limiting sliding block provided on the outer wall of the transmission mounting seat, and a self-lubricating wear-resistant coating is embedded at the contact point between the first limiting sliding block and the second sliding limiting groove to reduce sliding friction loss.

[0013] Preferably, the output end of the first electric telescopic rod is fixedly connected to the inner wall of the sliding sleeve. By extending and retracting the first electric telescopic rod, the sliding sleeve is driven to move axially along the mounting sleeve, thereby driving the arm to bend and release, thus realizing the expansion and contraction of the transmission mounting seat.

[0014] Preferably, the miniature gate is an electromagnetically controlled gate that is linked to the equipment's electrical control system. When the amount of debris accumulated in the collection chamber needs to be discharged, the gate opens to discharge the debris, ensuring the continuity of debris collection.

[0015] Preferably, in the debris collection mechanism, the dust collection chamber, the first connecting pipe, the retractable hose, the sliding connecting seat, the second connecting pipe and the collection chamber are connected in sequence to form a closed airflow channel.

A mesh is set on the side of the collection chamber near the powerful fan to intercept dust and prevent it from entering the fan chamber.

[0016] Preferably, the sliding connector is slidably disposed inside the sliding groove. A limiting protrusion is provided on the side of the sliding connector, and a limiting groove adapted to the limiting protrusion is correspondingly formed on the inner wall of the sliding groove. When the sliding connector slides within the sliding groove, the limiting protrusion and the limiting groove cooperate to restrict the movement direction of the sliding connector, preventing it from shifting under negative pressure suction. Simultaneously, the length of the retractable hose connected to the sliding connector is reserved to accommodate the sliding stroke of the sliding connector, ensuring that the pipeline connectivity of the debris collection mechanism is not affected during the adjustment of the expansion sensing mechanism.

[0017] Compared with the prior art, the advantages and positive effects of the present invention are as follows:

[0018] 1. In this invention, by using the rotational pressure sensor in the expansion sensing mechanism to measure distance in conjunction with the inner wall of the copper tube to be cut, the expansion range of the transmission mounting base can be automatically adjusted according to the tube diameter. Compared with traditional fixed clamps or manual positioning methods, this significantly improves the adaptability and positioning accuracy of copper tubes of different specifications, and reduces cutting errors caused by positioning deviations. It is especially suitable for the diverse copper tube cutting needs in the processing of refrigeration parts.

[0019] 2. In this invention, the adjustable cutting mechanism uses a second electric telescopic rod to drive the cutting blade, and with the guide structure of the third limiting sliding groove and the second limiting sliding block, it ensures that the cutting blade's movement trajectory is accurate. Combined with the circumferential cutting achieved by the rotating component, compared with traditional straight cutting, it not only improves cutting efficiency, but also makes the cut surface smoother and flatter, reduces subsequent processing costs, and reduces tool wear, extending tool life.

[0020] 3. In this invention, the chip collection mechanism and the powerful fan form a closed airflow channel, and the chip generated by cutting is collected in real time by negative pressure suction. The miniature gate and the electronic control system are linked to automatically remove chips. Compared with the simple chip cleaning method in existing cutting equipment, this invention effectively avoids chip accumulation from affecting cutting quality and equipment operation, maintains a clean working environment, reduces the risk of equipment failure, and ensures the continuity of cutting operations.

[0021] 4. In this invention, the limiting fit between the sliding connecting seat and the sliding groove, as well as the allowance design of the telescopic hose, ensure that the debris collection pipeline remains connected during the adjustment of the expansion sensing mechanism, thus ensuring stable suction. At the same time, the cross sliding seat cooperates with the first limiting sliding block at the bottom of the transmission mounting seat and is equipped with a self-lubricating wear-resistant coating, which reduces frictional loss during mechanism movement and improves the overall stability and reliability of the equipment. Compared with the complex and easily jammed mechanical structure of existing cutters, this invention is more flexible to operate and easier to maintain. Attached Figure Description

Figure 1 Appendix Figure 2 Appendix Figure 3 Appendix Figure 5 Appendix Figure 7 Appendix Figure 9As shown: A copper tube cutter for processing refrigeration parts includes a mounting sleeve 1. An expansion sensing mechanism 2 is fitted onto the outer wall of the mounting sleeve 1. The expansion sensing mechanism 2 includes four transmission mounting seats 204. One transmission mounting seat 204 houses an adjustable cutting mechanism 3, and the other three transmission mounting seats 204 are interconnected with a debris collection mechanism 4. A rotating assembly 5 is rotatably connected to the tail of the mounting sleeve 1. The expansion sensing mechanism 2 includes a sliding sleeve 201. A set of rotating seats 202 is fixedly mounted on the outer wall of the sliding sleeve 201. A set of transmission bending arms 203 is rotatably connected to the outer wall of each rotating seat 202. The internal rotating shafts of the transmission bending arms 203 are rotatably connected to the interior of the transmission mounting seats 204. A set of pressure sensor mounting seats 205 is fixedly mounted inside each transmission mounting seat 204. A set of pressure sensor mounting seats 205 is rotatably connected to the interior of each set of pressure sensor mounting seats 205 via a shaft. The characteristic feature is that the outer wall of the set of rotation pressure sensors 206... The wall of the device cooperates with the pipe to be cut to measure distance and control the range of expansion of the transmission mounting seat 204 in all directions. This reduces the friction of the inner wall of the pipe during cutting. The expansion sensor mechanism 2 achieves precise positioning through a unique design, laying the foundation for subsequent work. The sliding sleeve 201 moves axially along the mounting sleeve 1 under the drive of the first electric telescopic rod 12, driving the rotating seat 202 and the transmission bending arm 203 to expand or contract the four transmission mounting seats 204. The rotating pressure sensor 206 contacts the outer wall of the copper pipe to measure distance and feeds the data back to the control system to precisely adjust the position of the transmission mounting seat 204 to ensure that the copper pipe is in the optimal cutting position. During this process, the first limiting sliding strip 13 on the outer surface of the mounting sleeve 1 cooperates with the cross sliding seat 14 to provide guidance and stable support for the movement of the transmission mounting seat 204, ensuring the accuracy of positioning. This precise positioning makes subsequent cutting operations more efficient and accurate, reducing cutting errors and material waste caused by positioning deviations. Example

[0034] Please see the appendix Figure 1 Appendix Figure 2 Appendix Figure 3 Appendix Figure 4 Appendix Figure 5 Appendix Figure 7 and attached Figure 9As shown: The adjustable cutting mechanism 3 includes a first mounting groove 301, a second electric telescopic rod 302 fixedly mounted inside the first mounting groove 301, a mounting plate 303 fixedly connected to the output end of the second electric telescopic rod 302, a cutting blade 304 fixedly mounted on the outer surface of the mounting plate 303, a set of third limiting sliding grooves 306 fixedly opened on the inner wall of the first mounting groove 301, a dust cover 305 fixedly mounted inside the first mounting groove 301 by screws, a set of second limiting sliding blocks 307 fixedly connected to the outer surface of the mounting plate 303, a through hole 308 opened inside the dust cover 305, the outer wall of the cutting blade 304 and the inside of the through hole 308 cooperate with each other. Embodiment 2 focuses on the adjustable cutting mechanism 3, which works closely with the expansion sensing mechanism 2 to complete the cutting task. After the expansion sensing mechanism 2 completes the positioning of the copper tube, the second electric telescopic rod 302 is activated, pushing the mounting plate 303 to move smoothly along the third limiting sliding groove 306, driving the cutting blade 304 to pass through the through hole 308 of the dust cover 305 to cut the copper tube. During this process, the movement path of the cutting blade 304 is precisely limited by the second limiting sliding block 307 and the third limiting sliding groove 306 to ensure cutting accuracy. At the same time, the motor 505 in the rotating assembly 5 drives the cutter to rotate through the meshing of the gear 507 and the gear ring 508 to achieve multi-angle cutting. The expansion sensing mechanism 2 maintains the stable positioning of the copper tube, providing a stable cutting object for the cutting blade 304, while the adjustable cutting mechanism 3 performs precise actions according to the cutting requirements. The two work together to greatly improve the flexibility and applicability of cutting. Example

[0035] Please see the appendix Figure 1 Appendix Figure 2 Appendix Figure 3 Appendix Figure 5 and attached Figure 6As shown: The debris collection mechanism 4 includes a set of second mounting slots 401, each of which has a dust collection chamber 402 inside. Each dust collection chamber 402 is interconnected by a first connecting pipe 403. A retractable hose 404 is fixedly connected to the surface flange of one of the dust collection chambers 402. The outer wall of the retractable hose 404 is inserted into the interior of one of the transmission mounting seats 204, and one end of the retractable hose 404 is fixedly connected to a sliding connecting seat 405. One end of the sliding connecting seat 405 is fixedly connected to a second connecting pipe 406. One end of the second connecting pipe 406 is fixedly connected to a collection chamber 407. A mesh 408 is fixedly connected to the bottom of the collection chamber 407, and a miniature gate 409 is fixedly connected to the outer wall of the collection chamber 407. The debris generated by the cutting operation will affect the working environment and equipment operation, and this mechanism effectively solves this problem. To solve this problem, the powerful fan 509 generates negative pressure suction under the drive of the motor 505. The dust collection chamber 402, the first connecting pipe 403, the retractable hose 404, the sliding connecting seat 405, the second connecting pipe 406, and the collection chamber 407 form a closed airflow channel. Under the action of negative pressure, debris is quickly sucked into the collection chamber 407. The screen 408 prevents debris from entering the powerful fan 509 and avoids equipment damage. The miniature gate 409 is linked with the equipment's electronic control system. When the amount of debris accumulated in the collection chamber 407 reaches the preset value, it automatically opens to discharge debris, ensuring the continuity of debris collection. During this process, the flexible sliding of the sliding connecting seat 405 in the sliding groove 21, combined with the reserved length of the retractable hose 404, ensures that the debris collection pipeline remains connected during the adjustment of the expansion sensor mechanism 2, and the suction is transmitted stably, effectively collecting debris. Example

[0036] Please see the appendix Figure 1 Appendix Figure 2 Appendix Figure 3 Appendix Figure 7 Appendix Figure 8 and attached Figure 9As shown: A fixed rotating ring 504 is fixedly connected to the outer surface of the mounting sleeve 1. A limiting rotating ring 503 is rotatably connected to the outer wall of the fixed rotating ring 504. A protective sleeve 502 is fixedly connected to the outer surface of the limiting rotating ring 503. An integrated pipe 501 is connected to one end flange of the protective sleeve 502. A mounting disc 506 is fixedly connected inside the protective sleeve 502. A mounting base for a motor 505 is fixedly connected to the outer surface of the mounting disc 506. The output end of the motor 505 rotates and engages with the interior of the mounting disc 506. A gear 507 is fixedly connected to the output end of the motor 505. A gear ring 508 meshes with the outer wall of the gear 507. The input end of a powerful fan 509 is fixedly connected to the output end of the motor 505. The rotating assembly 5 works in conjunction with other components. To enhance efficiency, the gear 507 at the output end of motor 505 meshes with the gear ring 508, driving the cutter to rotate as a whole, achieving multi-angle cutting. During rotation, the expansion sensor mechanism 2 continuously positions and fixes the copper tube, ensuring the stability of the copper tube's position during rotational cutting and providing a reliable foundation for cutting. The adjustable cutting mechanism 3 precisely controls the feed and cutting force of the cutting blade 304 according to cutting requirements, ensuring cutting quality. At the same time, the debris collection mechanism 4, under the action of the powerful fan 509, synchronously collects the debris generated during cutting, maintaining a clean working environment and preventing debris from interfering with the rotating parts and the cutting process. This collaborative work of multiple components enables the cutter to meet the cutting tasks of copper tubes with different shapes and angles, greatly expanding the application range of the equipment. Example

[0037] Please see the appendix Figure 1 Appendix Figure 2 Appendix Figure 5 and attached Figure 6As shown: In the debris collection mechanism 4, the dust collection chamber 402, the first connecting pipe 403, the retractable hose 404, the sliding connecting seat 405, the second connecting pipe 406, and the collection chamber 407 are sequentially connected to form a closed airflow channel. This, combined with the negative pressure suction of the powerful fan 509, constructs a dust transport path from the cutting area to the collection chamber 407. A mesh 408 is positioned on the side of the collection chamber 407 near the powerful fan 509 to intercept dust and prevent it from entering the fan chamber. The sliding connecting seat 405 is slidably disposed inside the sliding groove 21. A limiting protrusion is provided on the side of the sliding connecting seat 405, and a limiting groove corresponding to the limiting protrusion is provided on the inner wall of the sliding groove 21. When the sliding connecting seat 405 slides within the sliding groove 21, the limiting protrusion and the limiting groove cooperate to restrict the movement direction of the sliding connecting seat 405, preventing it from shifting under negative pressure suction. Simultaneously, the retractable hose connected to the sliding connecting seat 405... The 404 length is reserved to accommodate the sliding stroke of the sliding connecting seat 405, ensuring that the pipeline connectivity of the debris collection mechanism 4 is not affected during the adjustment of the expansion sensing mechanism 2. The first mounting seat 11 and the first electric telescopic rod 12 inside the mounting sleeve 1, and the first limit sliding strip 13 and the cross sliding seat 14 on the outer surface, provide a stable mounting base and motion guide for other functional mechanisms. The self-lubricating wear-resistant coating reduces the friction loss between the transmission mounting seat 204 and the cross sliding seat 14, improving the service life of the equipment. In terms of functional coordination, the electric control handle 6 and the tail grip handle 61 facilitate the operator's control of the equipment operation. Under the coordination of the control system, the expansion sensing mechanism 2, the adjustable cutting mechanism 3, the debris collection mechanism 4, and the rotating component 5 complete the copper pipe positioning, cutting, debris collection, and multi-angle operation in an orderly manner. The components are interconnected and support each other, ensuring that the equipment can operate stably and efficiently under various working conditions. Example

[0038] Please see the appendix. Figure 1 - Appendix Figure 9As shown: A first mounting base 11 is fixedly connected inside the mounting sleeve 1. A mounting base for a first electric telescopic rod 12 is fixedly mounted on the outer surface of the first mounting base 11. A set of first limiting sliding strips 13 are fixedly connected to the outer surface of the mounting sleeve 1. A cross sliding seat 14 is fixedly mounted on the outer surface of the mounting sleeve 1. A second sliding limiting groove 15 is opened inside the cross sliding seat 14. A sliding groove 21 is opened on the outer wall of the sliding sleeve 201. An electric control handle 6 is fixedly connected to the outer wall of the integrated tube 501. The tail of the integrated tube 501... Each transmission mounting base 204 is fixedly connected to a tail grip handle 61. A first limiting sliding block 207 is fixedly connected to the bottom of each transmission mounting base 204. The inner wall of the second sliding limiting groove 15 of the cross sliding base 14 slides in cooperation with the first limiting sliding block 207 on the outer wall of the transmission mounting base 204. A self-lubricating wear-resistant coating is embedded at the contact point between the first limiting sliding block 207 and the second sliding limiting groove 15 to reduce sliding friction loss. The output end of the first electric telescopic rod 12 is fixedly connected to the inner wall of the sliding sleeve 201. The first electric telescopic rod... The telescopic rod 12 extends and retracts, driving the sliding sleeve 201 to move axially along the mounting sleeve 1, which in turn links the transmission arm 203 to realize the expansion and contraction of the transmission mounting base 204. The miniature gate 409 is an electromagnetically controlled gate, linked with the equipment's electrical control system. When the accumulated debris in the collection bin 407 needs to be discharged, it opens to discharge debris, ensuring the continuity of debris collection. The first electric telescopic rod 12 provides power to the expansion sensing mechanism 2, driving the sliding sleeve 201 to move, thereby realizing the expansion and contraction of the transmission mounting base 204. The second electric telescopic rod 302 provides power to the adjustable cutting mechanism 3 and controls the feed of the cutting blade 304. Under the control of the control system, the two precisely adjust their actions according to the diameter of the copper tube and the cutting requirements. At the same time, the motor 505 serves as the power source for the rotating component 5 and the powerful fan 509. On the one hand, it drives the cutter to rotate, and on the other hand, it provides suction for debris collection. These power components work closely with the various functional mechanisms. Through precise power transmission and adjustment, the equipment can complete the copper tube cutting work efficiently and accurately.

[0039] Usage and working principle of this device: Usage: Device placement: Carefully place the entire cutter into the copper tube to be cut, ensuring the device is positioned on the central axis of the copper tube to lay the foundation for subsequent operations. Parameter setting: The operator uses the electric control handle 6 on the outer wall of the integrated tube 501 to set the extension parameters of the first electric telescopic rod 12 and the second electric telescopic rod 302, as well as the operating parameters such as the speed of the motor 505, according to the copper tube diameter and cutting length requirements. Start operation: Press the start button; the device begins operation, sequentially completing a series of operations including positioning, cutting, and debris collection. Cutting completion: After the cutting operation is finished, the device automatically stops. Turn off the power using the electric control handle 6, remove the cutter from the copper tube, and collect the debris in the collection chamber 407. The debris can be discharged and cleaned through the miniature gate 409. The working principle involves intelligent positioning and adaptive expansion: After the equipment starts, the first electric telescopic rod 12 begins operation, its output end pushing the sliding sleeve 201 to move axially along the mounting sleeve 1. The rotating seat 202 on the outer wall of the sliding sleeve 201 drives the transmission arm 203 to rotate, causing the four transmission mounting seats 204 to gradually expand outwards. When the rotational pressure sensor 206 inside the transmission mounting seat 204 is tightly fitted against the inner wall of the copper tube, the sensor senses the tube wall pressure and distance in real time and feeds the data back to the control system. Based on this data, the control system precisely adjusts the expansion degree of the transmission mounting seats 204, ensuring the cutter is stably positioned inside the copper tube, while optimizing the cutting position and reducing friction between the cutter and the tube wall during cutting, ensuring... The accuracy and stability of the cutting operation, efficient rotary cutting: After positioning, the adjustable cutting mechanism 3 and the rotating component 5 work together. The second electric telescopic rod 302 pushes the mounting plate 303. The second limiting sliding block 307 on the outer surface of the mounting plate 303 cooperates with the third limiting sliding groove 306 of the first mounting groove 301 for guidance, driving the cutting blade 304 to move smoothly and pass through the through hole 308 of the dust cover 305, contacting the inner wall of the copper tube. At the same time, the motor 505 starts, and the gear 507 at its output end meshes with the gear ring 508, driving the cutter to rotate inside the copper tube. As the equipment rotates, the cutting blade 304 moves in a circular motion along the inner wall of the copper tube, achieving 360° continuous cutting and ensuring that the copper tube is completely cut off. This rotary cutting method not only It can reduce the accumulation of cutting errors, making the cutting surface smoother, and can also evenly distribute the force on the cutting blade, reduce cutting resistance, reduce equipment load, and extend the service life of the blade and equipment. Simultaneous debris collection: During the cutting process, the motor 505 in the rotating assembly 5 simultaneously drives the powerful fan 509 to operate, generating negative pressure suction. The dust collection chamber 402, the first connecting pipe 403, the retractable hose 404, the sliding connecting seat 405, the second connecting pipe 406, and the collection chamber 407 form a closed airflow channel. The debris generated during cutting is dispersed in all directions due to the centrifugal force and airflow disturbance caused by rotation. Under the action of negative pressure suction, it is quickly sucked into the collection chamber 407. The mesh 408 at the bottom of the collection chamber 407 effectively blocks debris, preventing it from entering the powerful fan 509 and causing damage.When the amount of debris accumulated in the collection chamber 407 reaches a preset value, the electromagnetically controlled miniature gate 409, linked to the equipment's electrical control system, automatically opens to discharge the debris. During this process, the sliding connecting seat 405 slides flexibly within the sliding groove 21. Its side limiting protrusions cooperate with the limiting groove to ensure accurate movement. Simultaneously, the extended length of the telescopic hose 404 ensures that the debris collection pipeline remains connected regardless of changes in the copper pipe diameter during the cutting process, maintaining stable suction transmission and efficiently completing the debris collection work. This keeps the inside of the pipe clean, ensuring continuous cutting operations. Precise control and coordinated operation: Operators control the system via electrical... Handle 6 and tail grip handle 61 are used to operate the equipment from outside the copper tube. The electric control handle 6 can remotely send commands to precisely control the extension and retraction of the first electric telescopic rod 12 and the second electric telescopic rod 302, as well as the speed and start / stop of the motor 505, achieving precise operation.
