Description

Technical Field

[0001] The invention relates to the technical field of pipe cutting, and in particular to a multi-angle pipe cutting device. Background Art

[0002] In the field of industrial processing, especially in heavy industries such as construction, shipbuilding, petrochemical and automobile industries, pipe cutting is a key step in the production process. Although the existing pipe cutting technology can achieve basic cutting functions, there are still some significant technical limitations and challenges, which hinder the improvement of production efficiency and the optimization of product quality.

[0003] For example, devices that allow the blade to rotate around the pipe to cut the pipe can usually only perform cutting operations at a fixed angle, such as 90-degree vertical cutting. This restrictive design does not support bevel cutting such as 30 or 45 degrees, which limits the application of pipes in complex structure assembly. In addition, when the blade rotates around the pipe to cut, a large amount of debris is generated. Existing devices usually collect these debris by setting a collection frame under the cutting area. However, this collection method is not always effective, especially when the cutting speed is fast, the management of debris becomes a problem, affecting the cleanliness of the working environment and the safety of the operator. Although some equipment is equipped with brushes or other cleaning structures to remove debris generated during the cutting process, the effectiveness of these cleaning structures is usually limited by their relative position to the pipe. When cutting at multiple angles, the cleaning structure may not maintain effective contact with the surface of the pipe, resulting in low cleaning efficiency. Summary of the invention

[0004] The purpose of the present invention is to improve cutting accuracy, optimize the working environment, and enhance the versatility of the equipment.

[0005] In order to achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a multi-angle pipe cutting device, comprising a machine tool and two bed plates fixed on the top thereof, a connecting piece is slidably connected between the two bed plates, a ring body is rotatably connected between the connecting pieces, a support piece that runs through the machine tool is rotatably connected at the bottom of the ring body, the bottom of the support piece is connected to the output end of the first motor, a first support plate and a second support plate are fixed to the support piece, a second motor that drives the ring body to rotate is fixed on the top of the first support plate, and a collection frame is provided at the bottom of the inner ring of the ring body;

[0006] Rectangular plates are provided at both ends of the inner circle of the ring body, and cutting blades and gear rods are installed on the rectangular plates. The gear rod passes through the ring body and is rotatably connected to the rotating rod at the bottom. Connecting rods are rotatably connected to the tops of both ends of the rotating rod. The connecting rods pass through the ring body and are fixedly connected to a mounting plate. A cleaning structure, a chip suction structure and an auxiliary clamping structure are provided on the mounting plate. A driving structure for driving the gear rod to move is installed in the inner cavity of the ring body.

[0007] As a further description of the above technical solution: the first motor is fixedly connected to the bottom of the machine tool, an annular convex tooth is fixed on the outer ring ring, the second motor is fixed with a main gear meshing with the annular convex tooth, the first support plate is fixed with a cannula, the collection frame is fixed with a U-shaped tube, and the cannula is inserted into the other side of the U-shaped tube.

[0008] As a further description of the above technical solution: the bottom of the second support plate is slidably connected to the top of the machine tool, an electric push rod is fixed on the top of the second support plate, the output end of the electric push rod is fixedly connected to the U-shaped tube, and a number of pipe clamps are fixed between the two side bed plates.

[0009] As a further description of the above technical solution: the driving structure includes a driving motor fixed in the inner cavity of the ring body, a driving gear is fixed to the output end of the driving motor, a transmission gear and a double-headed gear are rotatably connected in the inner cavity of the ring body, the gear rod is meshed with the double-headed gear, and the other end of the double-headed gear and the driving gear are both meshed with the transmission gear.

[0010] As a further description of the above technical solution: the cleaning structure includes a first spring telescopic rod fixed on the mounting plate, and a brush head is fixed to the far end of the first spring telescopic rod.

[0011] As a further description of the above technical solution: the auxiliary clamping structure includes a second spring telescopic rod fixed on the mounting plate, and a clamping wheel is fixed to the far end of the second spring telescopic rod.

[0012] As a further description of the above technical solution: the chip suction structure includes a chip suction box installed in the inner cavity of the ring body, a chip suction head is fixed on the mounting plate, and the chip suction box and the chip suction head are connected through a chip suction pipe.

[0013] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0014] 1. The second motor drives the ring body to rotate, so that the cutting blade rotates evenly along the outer ring of the pipe, thereby evenly cutting the outer wall of the pipe. This uniform rotation cutting method significantly improves the cutting accuracy and efficiency. The first motor drives the ring body to rotate through the support member, allowing the cutting blade to be adjusted to different angles, thereby meeting the multi-angle cutting requirements and increasing the application range of the equipment;

[0015] 2.

This design enables the device to flexibly handle pipe fittings of various sizes, improving the practicality and flexibility of the device;

[0016] 3. Through the synergistic effect of the rotating rod and the connecting rod, it is ensured that when the ring body rotates from different angles to cut the pipe, the cleaning structure, the chip suction structure and the auxiliary clamping structure on both sides of the cutting blade can always be close to the outer wall of the pipe. This not only improves the cleaning efficiency and reduces the cleaning time after work, but also enhances the stability of the pipe during the cutting process and avoids cutting errors caused by the movement of the pipe;

[0017] 4. The design of the ring body integrates the functions of cleaning, chip suction and clamping, which improves the working efficiency by simplifying the operating steps. The chip suction structure effectively collects the debris generated during the cutting process through the chip suction box and the chip suction head to keep the working environment clean. The auxiliary clamping structure provides additional support through the second spring telescopic rod and the clamping wheel to ensure the fixation and stability of the pipe during the cutting process.

[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] See also Figure 1-Figure 12 The present invention provides a multi-angle pipe cutting device, including a machine tool 10 and two bed plates 11 fixed on the top thereof, a connecting piece 12 is slidably connected between the two bed plates 11, a ring body 13 is rotatably connected between the connecting pieces 12, a support piece 14 that penetrates the machine tool 10 is rotatably connected at the bottom of the ring body 13, the bottom of the support piece 14 is connected to the output end of the first motor 15, a first support plate 16 and a second support plate 17 are fixed to the support piece 14, a second motor 18 that drives the ring body 13 to rotate is fixed on the top of the first support plate 16, and a collecting frame 19 is provided at the bottom of the inner circle of the ring body 13;

[0040] Rectangular plates 20 are provided at both ends of the inner ring of the ring body 13, and a cutting blade 21 and a gear rod 22 are mounted on the rectangular plate 20. The gear rod 22 passes through the ring body 13 and is rotatably connected to the rotating rod 23 at the bottom. The two ends of the rotating rod 23 can be telescoped for a certain distance. The tops of the two ends of the rotating rod 23 are rotatably connected to the connecting rod 24, which passes through the ring body 13 and is fixedly connected to the mounting plate 25. The mounting plate 25 is provided with a cleaning structure 30, a debris suction structure 40 and an auxiliary clamping structure 50. A driving structure 60 for driving the gear rod 22 to move is installed in the inner cavity of the ring body 13;

[0041] The support member 14 drives the ring body 13 to rotate and find a suitable cutting angle, so that the device can adapt to cutting requirements at various angles, greatly improving the flexibility and adaptability of cutting. When the ring body 13 rotates and causes the cleaning structure 30, the chip suction structure 40 and the auxiliary clamping structure 50 at both ends of the cutting blade 21 to be at different distances from the pipe fitting, the toothed rod 22 driven by the driving structure 60 moves, and the various structures at both ends of the cutting blade 21 will also move closer to or away from the pipe fitting accordingly, thereby driving the cleaning structure 30, the chip suction structure 40 and the auxiliary clamping structure 50 to move. This dynamic adjustment ensures that no matter what angle the cutting is performed, the cleaning structure 30, the chip suction structure 40 and the auxiliary clamping structure 50 can effectively contact the pipe fitting, thereby improving the cutting accuracy, reducing the scattering of debris, and maintaining the stability of the pipe fitting during the cutting process.

[0042] Specifically, during the rotation of the ring body 13, the cleaning structure 30, the chip suction structure 40 and the auxiliary clamping structure 50 at both ends of the cutting blade 21 will approach and move away from the pipe fitting, respectively, resulting in inconsistent distances between the components at both ends of the cutting blade 21 and the pipe fitting. When the driving structure 60 drives the gear rod 22 to move toward the pipe fitting, the cleaning structure 30, the chip suction structure 40 and the auxiliary clamping structure 50 installed on the rectangular plate 20 also move toward the pipe fitting.

[0043] The cleaning structure 30, the scrap suction structure 40 and the auxiliary clamping structure 50 which are closer to the pipe will first contact the pipe, and drive the connecting rod 24 to move in the opposite direction of the moving direction of the gear rod 22 during the continuous movement of the gear rod 22, and the rotating rod 23 connected to the connecting rod 24 will also rotate in the direction of the movement of the connecting rod 24;

[0044] The connecting rod 24 at the other end of the rotating rod 23 drives the cleaning structure 30, the scrap suction structure 40 and the auxiliary clamping structure 50 away from the pipe to move in the moving direction of the toothed rod 22, so that the cleaning structure 30, the scrap suction structure 40 and the auxiliary clamping structure 50 at both ends of the cutting blade 21 can be close to the pipe during cutting at different angles;

[0045] Specific observations Figure 1 , Figure 3 , Figure 4 , Figure 7 , Figure 8 , Fig. 9 , Fig.10 and Fig.11 It can be seen that the first motor 15 is fixedly connected to the bottom of the machine tool 10, the outer ring of the ring body 13 is fixed with an annular convex tooth 131 for receiving and transmitting power, the second motor 18 is fixed with a main gear 181 meshing with the annular convex tooth 131, and this configuration allows the second motor 18 to accurately drive the ring body 13 to rotate through the main gear 181, the first support plate 16 is fixed with a cannula 161, and the collection frame 19 is fixed with a U-shaped tube 191, one end of the U-shaped tube 191 is inserted into the cannula 161, and when the ring body 13 rotates, the support member 14 drives the collection frame 19 to rotate together through the cannula 161 and the U-shaped tube 191;

[0046] The bottom of the second support plate 17 is connected to the top of the machine tool 10 through a sliding mechanism, which allows the second support plate 17 to slide on the top of the machine tool 10. An electric push rod 171 is fixed to the top of the second support plate 17. The output end of the electric push rod 171 is fixedly connected to the U-shaped tube 191. The movement of the electric push rod 171 can drive the U-shaped tube 191 and the collection frame 19 to move, thereby adjusting the distance between the collection frame 19 and the ring body 13. When the debris in the collection frame 19 needs to be emptied, the operator can control the electric push rod 171 to move the collection frame 19 away from the ring body 13, thereby facilitating the staff to remove the debris safely and easily without disassembling other components.

[0047] Specific observations Figure 5 , Figure 6 , Fig.10 and Fig.12 It can be seen that the driving structure 60 includes a driving motor 61 fixed in the inner cavity of the ring body 13. The first motor 15, the second motor 18 and the driving motor 61 can automatically lock the rotating shaft, that is, after the motor stops running, the output shaft can be fixed at a certain position to prevent it from rotating. For example, a mechanical brake is installed, and a brake pad or a brake is used to apply friction to the rotating shaft when the motor stops, so as to achieve a locking effect;

[0048] A driving gear 62 is fixed to the output end of the driving motor 61, and the gear is used as a driving gear to drive the subsequent transmission system. The inner cavity of the ring body 13 is rotatably connected to a transmission gear 63 and a double-headed gear 64, and a plurality of pipe clamps 70 are fixed between the bed plates 11 on both sides;

[0049] The function of the transmission gear 63 is to receive power from the driving gear 62 and transmit it to the double-headed gear 64. The double-headed gear 64 has two gear ends, one end is meshed with the driving gear 62, and the other end is meshed with the transmission gear 63. The design of the double-headed gear 64 is to bridge the power transmission between the transmission gear 63 and the gear rod 22 to ensure the effective transmission of power.

[0050] The gear rod 22 is mounted on the inner ring of the ring body 13 and meshes with one end of the double-headed gear 64. The main function of the gear rod 22 is to convert the rotational power received from the double-headed gear 64 into a linear motion, thereby driving the cutting blade 21 to move toward the pipe.

[0051] Specific observations Figure 2 , Figure 6 and Fig.11 It can be seen that the cleaning structure 30 includes a first spring telescopic rod 31 fixed on the mounting plate 25, and a brush head 32 is fixed to the far end of the first spring telescopic rod 31. The brush head 32 is used to remove debris and impurities on the surface of the pipe during or after cutting. The material of the brush head 32 is selected in consideration of wear resistance and cleaning effect. It is usually made of materials such as steel wire or nylon to ensure efficient cleaning and a long service life. During the cutting process, as the ring body 13 rotates and the cutting blade 21 moves, the brush head 32 moves along the surface of the pipe to effectively remove debris and dust generated along the cutting path.

[0052] Keep watching Figure 2 It can be seen that the auxiliary clamping structure 50 includes a second spring telescopic rod 51 fixed on the mounting plate 25, and a clamping wheel 52 is fixed to the far end of the second spring telescopic rod 51. The design of the clamping wheel 52 takes into account the protection of the surface of the pipe fitting, and is usually made of rubber or other flexible materials to prevent damage to the pipe fitting during the clamping process.

[0053] Keep watching Figure 2 , Figure 5 , Figure 6 , Figure 7 It can be seen that the debris suction structure 40 includes a debris suction box 41 installed in the inner cavity of the ring body 13, which serves as a collection container for debris and dust. The debris suction box 41 has a good sealing property to ensure that the sucked debris and dust will not escape. A debris suction head 42 is fixed to the mounting plate 25, and the debris suction head 42 can capture the scattered debris and dust. The debris suction box 41 is connected to the debris suction head 42 through a debris suction pipe 43, and the debris suction pipe 43 is responsible for transmitting the sucked debris and dust. The debris suction pipe 43 is designed to be soft enough to adapt to the movement of the debris suction head 42 while maintaining sufficient strength and sealing to ensure that there is no debris leakage. The debris suction power source is installed in the debris suction box 41, providing sufficient suction to suck the debris and dust from the debris suction head 42 into the debris suction box 41. This power source is usually a small but efficient electric vacuum cleaner component designed to be low-noise and high-efficiency to adapt to continuous industrial use.

[0054] Working principle:

[0055] 1. Use an external conveying device to convey the pipe to the operating position of the cutting device to ensure that the pipe is stable and avoid movement during the cutting process;

[0056] 2. Activate the second motor 18, which is responsible for driving the ring body 13 to rotate. The ring body 13 drives the cutting blades 21 mounted on the rectangular plates 20 at both ends of its inner ring, so that the cutting blades 21 rotate evenly along the outer ring of the pipe. At the same time, start the driving motor 61, and through the coordinated action of the driving gear 62, the transmission gear 63 and the double-headed gear 64, push the gear rod 22 to move toward the pipe, so that the cutting blade 21 approaches the pipe and starts cutting;

[0057] 3. As the toothed rod 22 moves, the clamping wheel 52 in the auxiliary clamping structure 50 will first contact the pipe fitting to provide additional stable support for cutting. The brush head 32 in the cleaning structure 30 will then contact the outer wall of the pipe fitting to start cleaning the debris generated by cutting. The chip suction box 41 in the chip suction structure 40 has generated suction before cutting begins. The chip suction head 42 effectively captures the debris floating in the air and transports it to the chip suction box 41 through the chip suction pipe 43. Larger debris falls directly into the collection frame 19 under the action of gravity.

[0058] 4. If angled cutting is required, first start the first motor 15, which drives the ring body 13 to rotate through the support 14 to find a suitable cutting angle. After the ring body 13 rotates to the ideal angle, lock the rotating shaft of the first motor 15, start the second motor 18 and the drive motor 61 again, let the ring body 13 rotate around the pipe, and the cutting blade 21 approaches the pipe to cut. In this process, the cleaning structure 30, the scrap suction structure 40 and the auxiliary clamping structure 50 that are closer to the pipe will first contact the pipe and The continuous movement of the gear rod 22 drives the connecting rod 24 to move in the direction opposite to the moving direction of the gear rod 22, and the rotating rod 23 connected to the connecting rod 24 also rotates in the direction of the movement of the connecting rod 24. The connecting rod 24 at the other end of the rotating rod 23 drives the cleaning structure 30, the chip suction structure 40 and the auxiliary clamping structure 50 away from the pipe fitting to move in the moving direction of the gear rod 22. As a result, the cleaning structure 30, the chip suction structure 40 and the auxiliary clamping structure 50 at both ends of the cutting blade 21 can approach the pipe fitting during cutting at different angles.

[0059] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
