Description

Technical Field

[0001] This invention relates to the field of metal pipe processing technology, and in particular to a highly practical metal pipe cutting device and its processing method. Background Technology

[0002] Metal pipe cutting is a material removal forming method in metal forming processes, and it still accounts for a large proportion in today's mechanical manufacturing. The metal pipe cutting process is a process of interaction between the workpiece and the cutting tool. The cutting tool removes excess metal from the workpiece and, under the premise of controlling productivity and cost, enables the workpiece to obtain geometric accuracy, dimensional accuracy and surface quality that meet the design and process requirements. To achieve this process, metal pipe cutting processing equipment is required.

[0003] Patent CN117798421B discloses a metal pipe cutting processing device and its processing method, including a base plate with two mounting plates fixedly connected to the upper end of the base plate; a positioning mechanism located in one of the mounting plates; a pipe feeding mechanism located in the other mounting plate; a duct mechanism located on the surface of the base plate; an adjustment mechanism located on the surface of the base plate; and a crossbar connected to the adjustment mechanism.

[0004] In the above case, the metal pipe is transported by a pipe feeding mechanism, and one end of the metal pipe is clamped by a positioning mechanism. The metal pipe is then cut by a cutting component. At the same time, a duct mechanism is used to absorb the chips and dust generated during cutting, and a cooling component is used to cool the cutting blade. However, in actual operation, only one end of the metal pipe is fixed, resulting in unstable clamping. The duct structure is also unable to absorb all the splashing chips, and the coolant discharged from the cooling component will scatter, affecting the cutting operation and reducing the practicality of the device. Summary of the Invention

[0005] The purpose of this invention is to provide a highly practical metal pipe cutting device and its processing method to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a highly practical metal pipe cutting device, comprising a cutting seat, side seats fixedly connected to both sides of the cutting seat, a fixing component rotatably connected to the inner side of the side seats, elastic cloths fixedly connected to the outer sides of adjacent ends of the two fixing components, two elastic cloths respectively fixedly connected to the two ends of the inner side of the cutting seat, the elastic cloths including a plurality of sleeves fixedly connected to the inner side, a common inner sleeve slidably connected between two adjacent sleeves, a cutting component fixedly connected to one side of the cutting seat located between the two elastic cloths, a bottom pipe fixedly connected to the middle end of the bottom of the cutting seat, and a top cover hinged to the top end of the cutting seat.

[0007] In a preferred embodiment, the fixing component includes a rotating seat rotatably connected to the inner side of the side seat. Both ends of the inner side of the rotating seat are rotatably connected to turntables. The two turntables on the same side are fixedly connected to the same connecting frame. The rotating seat has a rotating groove inside for the connecting frame to rotate. The bottom of the side seat is fixedly connected to a bracket.

[0008] In a preferred embodiment, an arc-shaped rack is fixedly connected to the top of the connecting frame, and a forward and reverse motor is fixedly connected to the inner side of the rotating seat near the arc-shaped rack. A first gear is fixedly connected to the output end of the motor, and the bottom end of the first gear meshes with the arc-shaped rack on the same side.

[0009] In a preferred embodiment, the turntable has several arc-shaped grooves on its inner side, and several drive frames are slidably connected to the turntable through the arc-shaped grooves. Each drive frame includes an inner rod near the rotating seat, and the inner rod is located inside the corresponding arc-shaped groove. Several drive frames are slidably in contact with both sides of the rotating seat.

[0010] In a preferred embodiment, there are three drive frames on the outer side of the same turntable, arranged in a ring. A clamping roller is rotatably connected to the outer side of the drive frame away from the cutting seat. A clamping plate is fixedly connected to the outer side of the drive frame at the other end of the turntable. The ferrule is fixedly connected to the outside of the clamping plate on the same side.

[0011] In a preferred embodiment, both ends of the rotary seat are fixedly connected to a limiting frame adapted to the inner rod. The inner rod is slidably connected to the inner side of the corresponding limiting frame. A drive motor is fixedly connected to the outer side of the drive frame at the end of the rotary seat away from the cutting seat and located below it. Its output end is fixedly connected to the corresponding clamping roller.

[0012] In a preferred embodiment, a gear ring is fixedly connected to the side of the rotary seat away from the cutting seat, and a rotary motor is fixedly connected to the outer side of the side seat, with a second gear fixedly connected to its output end. The second gear meshes with the gear ring on the same side.

[0013] In a preferred embodiment, the cutting assembly includes a side seat fixedly connected inside the cutting seat, a telescopic frame slidably connected inside the side seat, a mounting frame fixedly connected to one end of the telescopic frame located inside the cutting seat, the mounting frame including a mounting shaft rotatably connected to the other end, a blade bolted to one side of the mounting shaft, a waterproof motor fixedly connected to the outside of the mounting frame, and its output motor fixedly connected to the end of the mounting shaft away from the blade.

[0014] In a preferred embodiment, a nozzle is fixedly connected to one end of the telescopic frame near the mounting frame, which is obliquely opposite the end of the blade away from the telescopic frame. A water pipe is fixedly connected to the outside of the nozzle, and its other end passes through a side seat. An electric cylinder is fixedly connected to the side of the side seat away from the cutting seat, and its output end is fixedly connected to the end of the telescopic frame away from the mounting frame.

[0015] This invention also provides a processing method for a highly practical metal pipe cutting device, comprising the following steps: Step 1: Open the top cover of the cutting seat, pass the metal pipe to be processed through the two fixed components, and place the two ends of the pipe between the clamping rollers and clamping plates distributed in a ring on both sides. Start the two forward and reverse motors, drive the No. 1 gear to mesh and drive the arc rack to move, push the connecting frame and the turntable to rotate. The turntable squeezes the inner rod through the arc groove, driving multiple sets of drive frames to synchronously retract radially, so that the clamping rollers and clamping plates are tightly attached to the outer wall of the pipe, completing the double-end clamping and fixing of the pipe. At the same time, the clamping plates drive the ferrule to move. Utilize the sliding extension and contraction of the ferrule and the inner sleeve to completely cover the two ends of the cutting area of ​​the pipe with elastic cloth on both sides, forming a closed shielding structure. Close the top cover to complete the pre-processing preparation. Step 2: Connect coolant to the water pipe to ensure that the coolant is precisely sprayed from the nozzle to the cutting contact point between the blade and the pipe, thus pre-cooling and lubricating the cutting point. Start the waterproof motor to drive the blade to rotate at high speed, and at the same time start the electric cylinder to push the telescopic frame forward, so that the high-speed rotating blade contacts the rotating metal pipe and cuts the pipe. The metal chips and waste coolant generated during the cutting process are completely blocked by the elastic cloth and the cutting seat cavity, and fall to the bottom of the cutting seat under the action of gravity, and are discharged and collected through the bottom pipe. Step 3: Simultaneously start the rotating motors on both sides, drive the gear ring and the rotating seats on both sides to rotate synchronously through the second gear, and drive the pipe to rotate, so that the blade makes a circular cut on the pipe until the pipe is cut off. Then turn off the waterproof motor and the nozzle, and drive the two drive motors in the opposite direction to drive the clamping rollers to rotate, and transport the two ends of the cut pipe from the two side seats respectively to complete the cutting work.

[0016] Compared with the prior art, the beneficial effects of the present invention are: This invention, by setting a fixing component, can simultaneously clamp and position both ends of a metal pipe fitting, changing the traditional single-end fixing clamping method and realizing double-end limiting and fixing of the pipe fitting. This greatly improves the stability of the pipe fitting during the cutting process, effectively avoids pipe fitting shaking and displacement, ensures a flat cutting surface and accurate dimensions, and significantly improves the pipe fitting cutting precision.

[0017] This invention utilizes a flexible enclosed structure composed of an elastic cloth, a clamping sleeve, and an inner sleeve. After the pipe is clamped, it can provide all-around protection to the cutting area. Metal chips generated during the cutting process are enclosed inside the cutting seat, preventing them from flying everywhere. At the same time, the bottom tube can collect and discharge the chips uniformly, completely solving the problems of incomplete chip adsorption and poor dust removal in traditional equipment, thus optimizing the processing environment.

[0018] This invention, by setting up a ring-shaped three-point synchronous centering clamping structure, combined with the precise limiting constraint of the drive structure by the limiting frame, enables multiple clamping points to extend and retract synchronously and be subjected to uniform force. This effectively ensures the coaxiality and centering of the metal pipe after clamping, and eliminates problems such as unilateral force deviation and loosening. During the high-speed rotation and cutting of the pipe, it can maintain a high-strength clamping state, greatly improving the structural stability under cutting conditions, fundamentally avoiding the micro-vibration of the pipe, and further ensuring the high-precision machining effect of the pipe cutting.

[0019] This invention features an adaptively adjustable clamping structure that can not only clamp and fix metal pipe fittings of different diameters within an adjustable range, but also drive the pipe fittings to rotate at a uniform speed. This, combined with the blade, enables uniform annular cutting, reduces cutting resistance, and improves cutting efficiency and surface smoothness. The equipment has a wide range of adaptability, a high degree of automation, and is extremely practical. Attached Figure Description

[0024] Please see Figures 1-6 This invention provides a highly practical metal pipe cutting device, including a cutting seat 1. The cutting seat 1 is the core processing cavity of the device, providing a closed processing space for pipe cutting, effectively shielding debris and coolant, and avoiding pollution of the working environment. Side seats 2 are fixedly connected to both sides of the cutting seat 1. The side seats 2 are used to support and install fixing components, ensuring the stable operation of the clamping and rotating structure. Fixing components are rotatably connected to the inner side of the side seats 2, used for centering, clamping, limiting, and rotating the ends of the metal pipe. Elastic cloths 18 are fixedly connected to the outer sides of adjacent ends of the two fixing components. The two elastic cloths 18 are respectively fixedly connected to the two ends of the inner side of the cutting seat 1. The elastic cloths 18 have extensible deformation characteristics, can adaptively expand and contract with the clamping of the pipe, and always wrap around the outer side of the cutting area. 8 includes several ferrules 14 fixedly connected on the inner side. The same inner sleeve 15 is slidably connected between two adjacent ferrules 14. Through the sliding cooperation between the ferrules 14 and the inner sleeve 15, the elastic cloth 18 can be adaptively stretched and opened and closed to adapt to the sealing and shielding requirements of pipe fittings of different diameters. The number of ferrules 14 and inner sleeves 15 on the same side is the same and they are distributed in a ring staggered manner. The cutting seat 1 is fixedly connected to a cutting component on one side between two elastic cloths 18 to complete the automatic feeding and cutting operation of metal pipe fittings. The bottom middle of the cutting seat 1 is fixedly connected to a bottom pipe 28 for unified collection and discharge of cutting chips and waste coolant. The top of the cutting seat 1 is hinged to a top cover 19, which can be opened and closed freely to facilitate the loading, inspection and maintenance of pipe fittings. After closing, it further improves the sealing performance of the cavity.

[0025] Please see Figures 1-6 The fixed component includes a rotating seat 3 rotatably connected to the inner side of the side seat 2. The rotating seat 3 is the main support of the clamping structure and can rotate as a whole, driving the pipe to rotate synchronously. Both ends of the inner side of the rotating seat 3 are rotatably connected to turntables 4. The two turntables 4 on the same side are fixedly connected to the same connecting frame 5. The connecting frame 5 is used to link the turntables 4 on both sides to rotate synchronously. The rotating seat 3 has a rotating groove 6 inside for the connecting frame 5 to rotate, providing space for the swing adjustment of the connecting frame 5. The bottom of the side seat 2 is fixedly connected to a bracket 32, which provides stable support for the overall structure and ensures stable operation of the equipment.

[0026] Please see Figures 1-6An arc-shaped rack 7 is fixedly connected to the top of the connecting frame 5. The arc-shaped rack 7 swings synchronously with the connecting frame 5. A forward and reverse motor 16 is fixedly connected to the inner side of the rotating seat 3 near the arc-shaped rack 7. A first gear 8 is fixedly connected to its output end. The bottom end of the first gear 8 meshes with the arc-shaped rack 7 on the same side.

Each drive frame 10 includes an inner rod 11 near the rotating seat 3. The inner rod 11 is located inside the corresponding arc-shaped groove 9. When the turntable 4 rotates, it squeezes the inner rod 11 through the arc-shaped grooves 9, causing the drive frame 10 to move radially. Several drive frames 10 slide in contact with both sides of the rotating seat 3 to ensure stable sliding.

[0028] Please see Figures 1-6 There are three drive frames 10 on the outer side of the same turntable 4, which are arranged in a ring. The three-point ring clamping structure has a good centering effect and uniform force, effectively ensuring the coaxiality of the pipe fittings.

The clamping roller 12 can rotate to realize the feeding and discharging of the pipe fittings. The drive frame 10 at the other end of the rotating seat 3 is fixedly connected to the clamping plate 13. The clamping plate 13 works with the clamping roller 12 to complete the clamping and positioning of the outer wall of the pipe fittings. The ferrule 14 is fixedly connected to the outside of the clamping plate 13 on the same side and moves synchronously with the clamping plate 13, driving the elastic cloth 18 to stretch and adjust.

[0029] Please see Figures 1-6 Both ends of the rotary seat 3 are fixedly connected to a limiting frame 17 adapted to the inner rod 11. The inner rod 11 is slidably connected to the inner side of the corresponding limiting frame 17. The limiting frame 17 slides and limits the inner rod 11 to ensure that the drive frame 10 only performs radial extension and retraction movements and avoids offset and jamming. The end of the rotary seat 3 away from the cutting seat 1 and located below the drive frame 10 is fixedly connected to a drive motor 33. Its output end is fixedly connected to the corresponding clamping roller 12 to provide power for the clamping roller 12 to rotate and feed and discharge materials.

A rotary motor 30 is fixedly connected to the outer side of the side seat 2. A second gear 31 is fixedly connected to its output end. The second gear 31 meshes with the gear ring 29 on the same side. Through gear meshing, the rotary seat 3 is driven to rotate as a whole, which in turn drives the clamped and fixed pipe to rotate at a uniform speed, thus realizing the ring cutting process.

[0031] Please see Figures 1-6The cutting assembly includes a side seat 20 fixedly connected inside the cutting seat 1. The side seat 20 is the mounting carrier for the cutting feed structure. A telescopic frame 21 is slidably connected inside the side seat 20. The telescopic frame 21 can stably extend and retract for feeding. A mounting frame 22 is fixedly connected to one end of the telescopic frame 21 located inside the cutting seat 1. The mounting frame 22 includes a mounting shaft rotatably connected to the other end. A blade 23 is bolted on one side of the mounting frame 22. The blade 23 is detachable and replaceable, making maintenance convenient. A waterproof motor 24 is fixedly connected to the outside of the mounting frame 22. Its output end is fixedly connected to the end of the mounting shaft away from the blade 23, driving the blade 23 to rotate at high speed to complete the cutting operation.

[0032] Please see Figures 1-6 A nozzle 25 is fixedly connected to one end of the telescopic frame 21 near the mounting frame 22. The nozzle is angled opposite the end of the blade 23 away from the telescopic frame 21, which can accurately spray coolant at the cutting point to achieve point cooling and lubrication. A water pipe 26 is fixedly connected to the outside of the nozzle 25, and its other end passes through the side seat 20 for connecting to an external coolant supply device. An electric cylinder 27 is fixedly connected to the side of the side seat 20 away from the cutting seat 1. Its output end is fixedly connected to the end of the telescopic frame 21 away from the mounting frame 22 to provide stable feed power for the blade 23 to feed and cut.

[0033] This invention also provides a processing method for a highly practical metal pipe cutting device, comprising the following steps: Step 1: Open the top cover 19 of the cutting seat 1, pass the metal pipe to be processed through the two fixed components, and place the two ends of the pipe between the clamping rollers 12 and the clamping plates 13 distributed in a ring on both sides. Start the two forward and reverse motors 16, drive the first gear 8 to mesh and drive the arc rack 7 to move, push the connecting frame 5 and the turntable 4 to rotate. The turntable 4 squeezes the inner rod 11 through the arc groove 9, and drives multiple sets of drive frames 10 to synchronously retract radially, so that the clamping rollers 12 and the clamping plates 13 are tightly attached to the outer wall of the pipe, and complete the double-end clamping and fixing of the two ends of the pipe. At the same time, the clamping plates 13 drive the ferrule 14 to move. By using the sliding extension and retraction of the ferrule 14 and the inner sleeve 15, the elastic cloth 18 on both sides completely covers the two ends of the cutting area of ​​the pipe, forming a closed shielding structure. Close the top cover 19 to complete the pre-processing preparation. Step 2: Connect coolant to water pipe 26 to spray coolant precisely from nozzle 25 to the cutting contact position between blade 23 and pipe fitting, thus completing the cooling and lubrication of the cutting point in advance. Start waterproof motor 24 to drive blade 23 to rotate at high speed. At the same time, start electric cylinder 27 to push telescopic frame 21 forward, so that the high-speed rotating blade 23 contacts the rotating metal pipe fitting and cuts the pipe fitting. The metal chips and waste coolant generated during the cutting process are completely blocked by elastic cloth 18 and the cavity of cutting seat 1, and fall to the bottom of cutting seat 1 under the action of gravity, and are discharged and collected through bottom pipe 28. Step 3: Simultaneously start the two rotating motors 30, which drive the gear ring 29 and the two rotating seats 3 to rotate synchronously through the second gear 31, and drive the pipe to rotate, so that the blade 23 performs a ring cut on the pipe until the pipe is cut off. Then turn off the waterproof motor 24 and the nozzle 25, and drive the two drive motors 33 in the opposite direction to drive the clamping roller 12 to rotate, and transport the two ends of the cut pipe from the two side seats 2 respectively, completing the cutting work.
