Description

Technical Field

[0001] This utility model relates to the field of pipe fitting processing technology, specifically a pipe fitting cutting and processing device. Background Technology

[0002] In modern industry, pipelines serve as the core carriers for fluid transport and energy transmission, with applications spanning multiple key sectors such as petrochemicals, municipal water supply, building heating, and shipbuilding. As industries increasingly demand higher standards for the safety, sealing, and adaptability of pipeline systems, the processing precision and production efficiency of pipeline fittings (such as elbows, tees, flanges, and clamps) have become crucial factors restricting the overall quality of pipeline projects. Cutting and machining, as the core process in pipeline fitting manufacturing, directly determines the subsequent assembly precision and performance of the fittings.

[0003] Currently, the cutting and processing of pipe fittings mainly relies on two technical solutions: one is the traditional manual cutting mode, in which operators manually cut according to pre-marked dimensions using tools such as angle grinders and plasma cutting guns. Although this method has low equipment investment costs and high operational flexibility, it has significant drawbacks: on the one hand, the stability of manual operation is greatly affected by the operator's experience and physical condition, which can easily lead to problems such as tilted cut surfaces and excessive dimensional deviations, resulting in misalignment and uneven gaps during subsequent welding of fittings, thus causing leakage risks; on the other hand, during manual cutting, operators need to be in close contact with high-speed rotating cutting parts, and there is serious metal shavings and sparks flying, which not only results in high labor intensity but also poses safety hazards such as cuts and burns. In addition, the daily processing capacity of a single person is only 30-50 pieces, which is difficult to meet the needs of large-scale production. Furthermore, in scenarios such as municipal engineering and emergency repairs, pipe fittings often need to be processed on-site to fit the actual installation dimensions. However, existing cutting equipment is generally bulky and has poor mobility, making it difficult to meet the needs of rapid on-site processing. At the same time, some equipment lacks effective debris collection and protection devices. The metal dust generated during the cutting process not only pollutes the working environment but also damages the respiratory system of operators, which does not meet the green environmental protection and occupational health requirements of modern industrial production.

[0004] In summary, current pipe fitting cutting and processing technology faces multiple challenges, including low precision, poor versatility, insufficient efficiency, and deficiencies in safety and environmental protection. It cannot meet the needs of various industries for high-quality, large-scale, and diversified processing of pipe fittings. Therefore, developing a pipe fitting cutting and processing device with automatic feeding, precise cutting, strong adaptability, and safety and environmental protection has become a key direction for solving the pain points of existing technologies.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figures 1-4 This utility model provides a technical solution: a pipe fitting cutting and processing device, including a device housing 1 and a motor 2. The motor 2 is disposed on the side of the device housing 1, and a processing mechanism is disposed on the inner side of the device housing 1. The processing mechanism includes a feeding unit and a cutting unit. The feeding unit is installed on the inner side of the device housing 1, and the cutting unit is installed on the inner side of the device housing 1. The feeding unit includes a bevel gear transmission assembly 3, which is connected to the output shaft of motor 2. A transmission shaft 4 is connected to the other side of the bevel gear transmission assembly 3. A movable wheel 5 is provided on the outer surface of the transmission shaft 4, located inside the device housing 1. A transmission gear 6 is connected to the outer surface of the transmission shaft 4, located outside the device housing 1. A connecting gear 7 is connected to the side of the transmission gear 6. A driven gear 8 is connected above the connecting gear 7. A movable groove 9 is provided inside the device housing 1. A rotating shaft 10 is connected to the inner side of the driven gear 8. A gear transmission assembly 11 is connected to the other end of the rotating shaft 10. A rotating shaft 12 is connected to the side of the gear transmission assembly 11. A movable wheel 13 is provided on the outer surface of the rotating shaft 12. A fixing block 14 is provided on the side of the device housing 1. An electric motor is located below the fixing block 14. The output shaft of the telescopic rod 15 is connected to the rotating shaft 10. By setting up a feeding unit, for pipes of different sizes, the electric telescopic rod 15 is activated, causing the rotating shaft 10 to move up and down, so that the second moving wheel 13 and the first moving wheel 5 come into contact with the upper and lower surfaces of the pipe. Then, the motor 2 is activated, which drives the transmission shaft 4 to rotate through the bevel gear transmission assembly 3, thereby causing the first moving wheel 5 to rotate. When the transmission shaft 4 rotates, the transmission gear 6, the connecting gear 7, and the driven gear 8 drive the rotating shaft 10 to rotate. Then, after being driven by the gear transmission assembly 11, the rotating shaft 12 drives the second moving wheel 13 to rotate, so that the second moving wheel 13 and the first moving wheel 5 rotate in opposite directions, thereby feeding the pipe.

[0018] The outer surfaces of the first movable wheel 5 and the second movable wheel 13 are provided with a protective layer, and the outer surface of the protective layer is provided with anti-slip texture. By providing the protective layer, the damage to the pipeline during material feeding is reduced. At the same time, by providing the anti-slip texture, the friction between the material and the pipeline is increased, thereby ensuring that the pipeline can be transported normally.

[0019] A side limiting component 16 is provided on the side of the device housing 1. A limiting wheel 17 is provided on the inner side of the side limiting component 16. A spring is provided inside the side limiting component 16. The position of the limiting wheel 17 can be changed by the extension and contraction of the spring during transportation of pipes of different sizes, thereby providing auxiliary limiting on both sides of the pipe.

[0020] The cutting unit includes a transmission belt assembly 18, which is connected to the outer surface of the transmission shaft 4. The other end of the transmission belt assembly 18 is connected to a central shaft 19. A rotating disk 20 is provided on the side of the central shaft 19 and inside the device housing 1. A connecting shaft 21 is provided on the other side of the rotating disk 20. A connecting rod 22 is movably connected to the outer surface of the connecting shaft 21. A placement plate 23 is movably connected to the other end of the connecting rod 22. A cutting assembly 25 is provided on the top of the placement plate 23. A limit rod 24 is provided inside the device housing 1. The placement plate 23 moves on the outer surface of the limit rod 24. Thus, when the cutting unit is installed and the transmission shaft 4 rotates, the transmission belt assembly 18 drives the central shaft 19 to rotate, which in turn drives the rotating disk 20 to rotate. This causes the connecting shaft 21 to move the placement plate 23 up and down on the outer surface of the limit rod 24, thereby further cutting the pipe by activating the cutting assembly 25.

[0021] The cutting assembly 25 consists of an output motor and a cutting blade. The output motor is located above the placement plate 23, and the cutting blade is mounted on the output shaft of the output motor. By starting the output motor, the cutting blade is rotated, thereby assisting in the cutting of the pipe.

[0022] An auxiliary pad 26 is provided on the upper inner side of the device housing 1. An arc-shaped surface is provided on the upper part of the auxiliary pad 26, so that when the pipe is located on the auxiliary pad 26, it provides auxiliary support when the pipe is cut through the auxiliary pad 26.

[0023] Rotating shaft 10 and rotating shaft 12 move inside the moving groove 9.

[0024] Working principle: Starting motor 2, its output shaft drives transmission shaft 4 to rotate via bevel gear transmission assembly 3. Transmission shaft 4 drives inner movable wheel 5 to rotate and outer transmission gear 6 to rotate. Transmission gear 6 drives rotating shaft 10 to rotate via connecting gear 7 and driven gear 8. Rotating shaft 10 then drives rotating shaft 12 and outer movable wheel 13 to rotate via gear transmission assembly 11. The rotating shaft 10 can also move up and down within the moving groove 9 via the electric telescopic rod 15 below the fixing block 14 on the side of the starting device housing 1, thereby adjusting the distance between movable wheel 13 and movable wheel 5, so that they contact the upper and lower surfaces of pipes of different sizes and rotate in opposite directions to achieve pipe loading. Simultaneously, the side limiting assembly 16 on the side of the device housing 1 utilizes an internal spring... The position of the inner limiting wheel 17 is adjusted by telescopic adjustment to provide auxiliary limiting for both sides of the pipeline during transportation. The protective layer and anti-slip texture on the outer surface of the moving wheel 1 5 and the moving wheel 2 13 respectively protect the pipeline and increase friction. When the drive shaft 4 rotates, it also drives the central shaft 19 to rotate through the drive belt assembly 18. The central shaft 19 drives the rotating disk 20 to rotate. The connecting shaft 21 on the rotating disk 20 drives the placement plate 23 to move up and down on the limiting rod 24 inside the device housing 1 through the connecting rod 22. The cutting assembly 25, which consists of an output motor and a cutting blade, moves accordingly at the top of the placement plate 23. The output motor is started to drive the cutting blade to rotate, and the pipeline located on the auxiliary pad 26 (the arc-shaped surface structure plays an auxiliary support role) located on the upper inner side of the device housing 1 is cut to achieve the coordinated operation of pipeline loading and cutting.
