Description

Technical Field

[0001] The utility model relates to the technical field of glass fiber reinforced plastic pipe processing, in particular to a pipe chamfering and cutting device. Background Art

[0002] FRP pipes are made of glass fiber reinforced plastic. They have the advantages of being lightweight, high-strength, and corrosion-resistant. They are widely used in chemical, petroleum, sewage treatment, desalination, and other fields. Currently, mechanical methods, adhesive bonding methods, and threaded connections are commonly used to connect high-pressure FRP pipes. Since both mechanical and adhesive bonding methods have different disadvantages, threaded connections are often used for high-pressure FRP pipes. For small-diameter FRP pipes, the method of bonding threads using a ring die is usually used. However, due to the deviation of the taper grinding at the end of the FRP pipe, the bonded threads do not start from the pipe end, resulting in a gap between the pipe end and the thread starting point. In order to meet the requirements of relevant standards, the blank part of the pipe needs to be cut and chamfered at the cut end.

[0003] Currently, there are two main methods for pipe chamfering: manual cutting and CNC lathe cutting. However, manual cutting often has problems such as low precision, large dimensional deviation, and hand cuts caused by hand-held cutting tools. Although CNC lathe chamfering has high precision, the clamping and positioning process is complicated, time-consuming and labor-intensive, and inefficient, and cannot meet the needs of mass production.

The pipe chamfering cutting device is used to cut the blank part of the pipe 100 and cut the chamfer, including a base 1, a feeding and clamping mechanism 2, a chamfering cutting mechanism 3 and a protective cover 5; wherein a guide rail 4 is provided on the base 1 along the conveying direction of the pipe 100; the feeding and clamping mechanism 2 is provided on the base 1, and the pipe 100 can pass through the feeding and clamping mechanism 2, and the feeding and clamping mechanism 2 can automatically clamp and fix the pipe 100; the chamfering cutting mechanism 3 is provided on the base 1, and the chamfering cutting mechanism 3 can slide on the guide rail 4 in the direction close to or away from the feeding and clamping mechanism 2, and the chamfering cutting mechanism 3 can selectively slide on the guide rail 4 or maintain a fixed position, so that the chamfering cutting mechanism 3 can automatically measure the cutting position of the pipe 100, cut the pipe 100 and cut the chamfer; the protective cover 5 is provided on the base 1, and can cover the feeding and clamping mechanism 2 and the chamfering cutting mechanism 3 to prevent cutting debris from splashing.

[0032] The loading and clamping mechanism 2 and the chamfering and cutting mechanism 3 can automatically complete the clamping, fixing and cutting of the pipe 100, avoiding the repetitive labor in manual operation. The chamfering and cutting mechanism 3 can automatically measure the position of the pipe 100 before cutting. The operator can control the chamfering and cutting mechanism 3 to slide on the guide rail 4 in the direction closer to or away from the loading and clamping mechanism 2, and flexibly adjust the specific position of the chamfering and cutting mechanism 3 according to the actual position of the pipe 100.

It is suitable for large-scale processing and production of pipe 100 and can be used on uninterrupted, long-term running production lines, greatly reducing manual intervention and improving production stability and continuity.

[0033] like Figure 1 As shown, in order to improve the safety of the pipe chamfering cutting device, in some embodiments, a transparent inspection door 51 that can be opened and closed is provided on the side of the protective cover 5. An audible and visual warning light 52 is provided on the protective cover 5. The audible and visual warning light 52, the inspection door 51, and the chamfering cutting mechanism 3 are electrically connected. The transparent inspection door 51 allows the operator to observe the cutting condition inside the device without opening the protective cover 5. When the device needs to be repaired, the inspection door 51 can be opened directly for quick repair, saving time. The inspection door 51 can be opened and closed by magnetic induction. The protective cover 5 is also provided with an audible and visual warning light 52. When the pipe chamfering cutting device is in operation and the inspection door 51 is open, the audible and visual warning light will sound an alarm, reminding the operator to close the inspection door 51 to ensure personnel safety.

[0034] like Figure 2As shown, in order to improve the cutting accuracy, in some embodiments, the chamfer cutting mechanism 3 includes a chamfer cutting frame 31 and a chamfer cutting assembly 32, and the chamfer cutting frame 31 is slidably connected to the guide rail 4; the chamfer cutting assembly 32 includes a slide module 321, a cutting motor 322 and a chamfer cutting disc 323; the slide module 321 is arranged on the side of the chamfer cutting frame 31 facing the feeding clamping mechanism 2, and the chamfer cutting disc 323 is arranged on the side of the slide module 321 facing the feeding clamping mechanism 2, and the cutting motor 322, the slide module 321 and the chamfer cutting disc 323 are connected to the guide rail 4. Electrical connection; utilizing the high motion accuracy and repeatability of the slide module 321, the position of the chamfer cutting disc 323 can be precisely controlled, so that the chamfer cutting disc 323 can be accurately aligned with the part to be cut, ensuring the stability and accuracy of the cutting position; at the same time, the slide module 321 is electrically connected to the cutting motor 322, realizing synchronous control, so that the position of the chamfer cutting disc 323 can be adjusted at any time during the cutting process, ensuring smooth cutting, and the cutting motor 322 can control the slide module 321 so that the chamfer cutting disc 323 can rotate forward or reverse. In order to ensure the stability of the installation of the chamfer cutting assembly 32, a slide module 321 mounting plate can be provided on the side of the chamfer cutting frame 31 facing the feeding clamping mechanism 2, and the slide module 321 is fixed to the slide module 321 mounting plate by bolts; a cutting motor 322 mounting seat can be provided on the side of the slide module 321 facing the feeding clamping mechanism 2 for installing the cutting motor 322, so that the overall installation of the chamfer cutting assembly 32 is more stable.

[0035] Continue as Figure 2As shown, in order to improve the stability of the chamfer cutting disc 323 during rotation, in some embodiments, the chamfer cutting assembly 32 further includes a rotary motor 324, a rotary support 325, and a rotary drive gear 326. The rotary support 325 is disposed between the slide module 321 and the chamfer cutting frame 31; the rotary drive gear 326 is disposed on the rotary support 325, and the rotary motor 324, the rotary support 325, and the rotary drive gear 326 are electrically connected. By installing the rotary support 325 between the slide module 321 and the chamfer cutting frame 31, the slide module 321 can be controlled to provide rotational support for the chamfer cutting disc 323, so that the cutting assembly is subjected to more uniform force during rotation, the center of gravity of the cutting assembly can be well balanced during rotation, and eccentric force or swing during rotation can be avoided, thereby enhancing stability during rotation, preventing a decrease in cutting accuracy due to vibration during rotation, and ensuring the flatness of the cut edge. The slewing drive gear 326 converts the power output from the slewing motor 324 into rotational motion. It is secured to the slewing support 325 via a bolt keyway, ensuring the stability of the slewing drive gear 326. This allows for smooth cutting even at high speeds and prevents deviations in the cutting angle. The slewing drive gear 326 is secured to the slewing motor 324 via a bolt keyway. This dual securing mechanism ensures a tight connection between the slewing drive gear 326 and the slewing motor 324, minimizing the possibility of loosening.

[0036] Continue as Figure 2As shown, in order to achieve high-precision measurement, in some embodiments, the chamfer cutting mechanism 3 also includes a distance measuring component 33, the distance measuring component 33 includes a laser sensor 331 and a distance measuring bracket 332, one end of the distance measuring bracket 332 is connected to the cutting motor 322, and the other end of the distance measuring bracket 332 is connected to the laser sensor 331, and the laser sensor 331 is located on the side of the chamfer cutting disc 323 facing the feeding clamping mechanism 2; by equipping the chamfer cutting mechanism 3 with the distance measuring component 33, the distance measuring component 33 can accurately measure and feedback the position of the pipeline 100, so that the pipeline chamfer cutting device can always maintain a consistent cutting position and angle, avoiding errors caused by manual measurement, while reducing human intervention, avoiding errors caused by manual marking and manual measurement, and utilizing the distance measuring component 33 and the chamfer cutting The components 32 are used in conjunction to enable the device to maintain stability and consistency in each cut; the distance measuring component 33 includes a laser sensor 331 and a distance measuring bracket 332. The laser sensor 331 has a high measurement accuracy, usually with an error at the millimeter level, and can monitor the distance between the pipe 100 and the cutting tool in real time; by locating the laser sensor 331 on the side of the chamfered cutting disc 323 facing the feeding clamping mechanism 2, closer to the feeding clamping mechanism 2, the position of the laser sensor 331 close to the cutting point helps to reduce the influence of external factors (such as vibration, light changes, etc.) on the measurement results, and can monitor the position of the pipe 100 in real time during the cutting process, adjust the motion trajectory of the cutting frame when necessary, optimize the cutting path, and also detect potential displacement or deviation earlier and issue an alarm in time. In other embodiments, the measuring component can also be an infrared rangefinder, which is not specifically limited here.

[0037] In order to improve the stability of the feeding clamping mechanism 2, in some embodiments, the feeding clamping mechanism 2 includes a feeding clamping frame 21 and an electric clamping member 22 with adjustable clamping force. The feeding clamping frame 21 is arranged on the base 1, and the pipe 100 can pass through the feeding clamping frame 21. The electric clamping member 22 is arranged at the pipe outlet end of the feeding clamping frame 21 and can automatically clamp and fix the pipe 100; wherein, the electric clamping member 22 with adjustable clamping force in the feeding clamping mechanism 2 allows the operator to flexibly adjust the clamping force according to the material, diameter and processing requirements of the pipe 100 to adapt to the fixing requirements of different pipes 100. For example, a lower clamping force can be set for brittle materials to avoid excessive clamping and causing damage to the surface of the pipe 100; for strong materials, the clamping force can be increased to ensure stability; at the same time, the automatic operation of the electric clamping member 22 does not require manual adjustment, and the pipe 100 can be quickly fixed after clamping, saving preparation and adjustment time, and further improving the operation convenience of the equipment. The electric clamping member 22 may be, but is not limited to, an electric three-jaw chuck or an electric four-jaw chuck, which is not specifically limited here.

[0038] To improve the stability of the conveying path of the pipe 100 and the production efficiency of the overall pipe chamfering and cutting device, in some embodiments, the pipe chamfering and cutting device is further provided with a conveying mechanism 6. The conveying mechanism 6 includes a conveying assembly 61. The conveying assembly 61 includes a tapered roller 611 and a roller support 612. The roller support 612 is disposed on the base 1 and is located at the pipe inlet end of the feeding and clamping mechanism 2. The tapered roller 611 is located on the roller support 612. The tapered roller 611 can maintain the conveying path of the pipe 100. The conveying assembly 61 and the feeding and clamping mechanism 2 in the conveying mechanism 6 cooperate with each other to provide a stable conveying path for the pipe 100. The shape of the tapered roller 611 in the conveying assembly 61 can effectively guide the pipe 100, and the roller support 612 can stably support the tapered roller 611, allowing the pipe 100 to move along the predetermined conveying path, reducing deviation or tilt of the pipe 100 during conveyance. The stable conveying path ensures continuous conveyance of the pipe 100, thereby improving overall production efficiency. Furthermore, the conveying mechanism 6 also includes a lifting component 62, which is arranged between the base 1 and the roller bracket 612. The lifting component 62 can drive the lifting and lowering of the conveying component 61; wherein the lifting component 62 is arranged between the base 1 and the roller bracket 612, so the lifting component 62 can automatically adjust the height of the tapered roller 611 according to the pipes 100 of different diameters and lengths, ensuring that the pipe 100 can smoothly enter the cutting area, improving the applicability of the device, and at the same time, the lifting component 62 can make the tapered roller 611 dock with the pipe 100 at the same height, reducing the operation time during the clamping process of the pipe 100 and improving the clamping efficiency.

[0039] In order to transport the pipe 100 to the correct position in the cutting area, in some embodiments, the pipe chamfer cutting device is further provided with a limiting assembly 7, which includes a lifting rod 71, a limiting plate 72 and a guide tube 73. The guide tube 73 is arranged in the base 1 along the vertical direction and is located between the feeding clamping mechanism 2 and the chamfer cutting mechanism 3. The lifting rod 71 is arranged in the guide tube 73, and the limiting plate 72 is connected to the top end of the lifting rod 71. The limiting plate 72 can be telescopically extended from the upper surface of the base 1 and can limit the forward path of the pipe 100; before the pipe 100 is transported, the limiting plate 72 can extend from the surface of the base 1 in the vertical direction through the lifting rod 71 and the guide tube 73, effectively limiting the forward path of the pipe 100, and ensuring that the pipe 100 is in the correct position in the cutting area during the transportation process; after the limiting plate 72 completes the positioning of the pipe 100, the limiting plate 72 can be retracted into the base 1 through the lifting rod 71 and the guide tube 73, without affecting the chamfer cutting mechanism 3 to cut the pipe 100.

[0040] Combine Figure 1 He Ru Figure 2As shown, in order to accurately control the distance between the chamfering cutting mechanism 3 and the loading and clamping mechanism 2, in some embodiments, the pipe chamfering cutting device is further provided with a feeding assembly 8, which is located on the side of the chamfering cutting mechanism 3 away from the loading and clamping mechanism 2. The feeding assembly 8 includes a traveling motor 81, a coupling 82 and a ball screw 83. The end of the coupling 82 away from the chamfering cutting mechanism 3 is connected to the traveling motor 81, the end of the coupling 82 close to the chamfering cutting mechanism 3 is connected to one end of the ball screw 83, and the other end of the ball screw 83 is connected to the chamfering cutting mechanism 3. The feeding assembly 8 can drive the chamfering cutting mechanism 3 to selectively move forward or backward along the guide rail 4. Among them, the feeding assembly 8 can accurately control the distance between the chamfering cutting mechanism 3 and the loading clamping mechanism 2. The drive of the traveling motor 81 enables the chamfering cutting mechanism 3 to move forward or backward quickly, reducing the operator's manual adjustment time and improving overall work efficiency; the coupling 82 transmits the power of the traveling motor 81 to the ball screw 83, and maintains the stability of the connection between the traveling motor 81 and the ball screw 83. The design of the ball screw 83 can drive the chamfering cutting mechanism 3 forward or backward along the guide rail 4. At the same time, the positioning accuracy of the ball screw 83 is high, so the feeding assembly 8 can improve the positioning accuracy of the cutting and reduce the cutting error.

[0041] Continue as Figure 1 As shown, in order to achieve full automation of pipe chamfer cutting and improve work efficiency, in some embodiments, a control panel 9 is provided on the protective cover 5, and the control panel 9, the feeding clamping mechanism 2, the chamfer cutting mechanism 3, the limit assembly 7 and the feed assembly 8 are all electrically connected; wherein the control panel 9 centrally manages each component, and the operator can easily control the operation of the entire cutting device through a visual interface, which reduces complex operating steps, greatly reduces the need for manual intervention, improves the automation level of the production line, and enables the operator to quickly adjust each link, respond to changes in the production process in a timely manner, and improve production efficiency.

[0042] The following is the operating process of the pipe chamfer cutting device:

[0043] First, input the specification information of the pipe 100 to be processed on the control panel 9, press the device start button, and the limit assembly 7 automatically rises and extends from the upper surface of the base 1 to the specified position;

[0044] Afterwards, the pipe 100 is transported from the pipe inlet end of the loading and clamping frame 21 along the pipe 100 conveying path by the conveying mechanism 6. The pipe 100 is transported to the designated position. The electric clamping member 22 located at the pipe outlet end of the loading and clamping frame 21 clamps the pipe 100. Then, the limiting assembly 7 automatically descends into the base 1.

[0045] Then, the chamfer cutting mechanism is driven by the feed assembly 8 to slide on the guide rail toward the loading clamping mechanism 2. After the distance measuring assembly 33 detects the blank cutting position of the pipe 100, the feed assembly 8 moves the chamfer cutting disc 323 to the cutting position.

[0046] Next, the cutting motor 322 drives the chamfering cutting disc 323 to rotate, and the rotary support 325 drives the slide module 321 to rotate forward one circle, completing the cutting of the blank portion of the pipe 100; then the slide module 321 continues to descend to the chamfering size position, and the rotary support 325 drives the slide module 321 to rotate backward one circle, completing the chamfering of the pipe 100;

[0047] Finally, after the cutting is completed, each mechanism returns to the starting position, the electric clamping member 22 releases the pipe 100, and the pipe 100 is moved out through the conveying assembly to cut the next pipe 100.
