Description

Technical Field

[0001] This utility model relates to the field of pipe processing technology, and in particular to a multi-angle pipe beveling machine. Background Technology

[0002] Pipe beveling machines are devices that use mechanical cutting to process bevels of a certain angle, shape, and size at the ends of pipes. They are mainly used for preparatory work before connecting and welding various pipes.

[0003] Besides welding, there are many other ways to connect pipes, such as socket joints and flange joints. In these connection methods, it is sometimes necessary to bevel the pipe ends at a specific angle to ensure the tightness and stability of the connection. Multi-angle pipe beveling machines can provide beveling at various angles to meet the needs of different connection methods.

[0004] Existing multi-angle pipe beveling machines cannot be precisely positioned and fixed when processing pipes, making it difficult to ensure the accurate relative position of the pipe axis and the beveling tool. This leads to deviations in dimensions such as beveling angle, depth, and width, increasing the workload of subsequent grinding and processing, and failing to meet design requirements and welding process standards. Utility Model Content

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0024] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0025] Reference Figure 1 and Figure 2This utility model provides an embodiment of a multi-angle pipe beveling machine, comprising a pedal 1, a connecting rod 2 fixedly connected to the inner wall of the pedal 1, a fixing ring 3 fixedly connected to the outer wall of the connecting rod 2, a spring 4 fixedly connected to the upper surface of the fixing ring 3, a base plate 5 fixedly connected to the upper surface of the spring 4, a rotating block 6 fixedly connected to the outer wall of the connecting rod 2, the outer wall of the rotating block 6 rotatably connected to the inner wall of the base plate 5, a push block 7 rotatably connected to the outer wall of the connecting rod 2, a support block 8 slidably connected to the outer wall of the push block 7, a guide rod 9 fixedly connected to the inner wall of the support block 8, a clamping block 10 fixedly connected to the outer wall of the guide rod 9, the lower surface of the clamping block 10 fixedly connected to the upper surface of the support block 8, the inner wall of the push block 7 slidably connected to the outer wall of the guide rod 9, and a cutting assembly provided on the inner wall of the base plate 5 for cutting pipes.

[0026] Specifically, pressing pedal 1 causes pedal 1 to drive connecting rod 2 to rotate. The rotating block 6, fixed on the outer wall of connecting rod 2, rotates on the inner wall of base plate 5, preventing connecting rod 2 from falling off during use. The rotation of connecting rod 2 on the inner wall of push block 7 allows push block 7 to slide on the outer wall of guide rod 9, providing a guiding effect. By fixing guide rod 9 to the inner wall of support block 8 and clamping block 10, push block 7 can be limited to prevent it from falling off. The spring 4 fixed on the lower surface of base plate 5 pulls the fixing ring 3, allowing connecting rod 2 to quickly reset. Setting push block 7 and clamping block 10 allows the pipe to be precisely fixed in the required position, ensuring that the axis of the pipe maintains an accurate relative position with the processing tool or cutting device of the beveling machine, thereby ensuring that the dimensional accuracy of the beveling angle, depth, width, etc., meets the design requirements and welding process standards.

[0027] Reference Figure 3 The cutting assembly includes a rotating plate 11, the outer wall of which is rotatably connected to the inner wall of a base plate 5. A hollow block 12 is slidably connected to the upper surface of the rotating plate 11. A motor 13 is fixedly connected to the inner bottom wall of the hollow block 12. A drive gear 14 is fixedly mounted on the output end of the motor 13. The outer wall of the drive gear 14 is rotatably connected to the inner wall of the hollow block 12. A transmission gear 15 is meshed with the tooth ends of the drive gear 14. A rotating rod 16 is fixedly connected to the inner wall of the transmission gear 15. The outer wall of the rotating rod 16 is rotatably connected to the hollow block 12. The inner wall of the hollow block 12 has a fixed gear 17 meshing with the tooth end of the transmission gear 15. The inner wall of the fixed gear 17 is fixedly connected to the cutting head 18. The outer wall of the cutting head 18 is rotatably connected to the inner wall of the hollow block 12. The inner wall of the cutting head 18 is threadedly connected to the cylindrical cutting head 29. The outer wall of the hollow block 12 is fixedly connected to the handle 19. The outer wall of the rotating plate 11 is fixedly connected to the first scale 20. The inner wall of the first scale 20 is slidably connected to the locking block 21. The lower surface of the locking block 21 is rotatably connected to the upper surface of the base plate 5.

[0028] Specifically, the locking block 21 causes the first dial 20 to engage with the inner wall of the base plate 5, allowing the rotating plate 11 fixed to the first dial 20 to allow the hollow block 12 to slide back and forth. The motor 13 drives the drive gear 14 to rotate on the inner wall of the hollow block 12, which in turn drives the transmission gear 15 and the rotating rod 16 to rotate together. During use, this linkage rotation on the inner wall of the hollow block 12 prevents it from falling off. The transmission gear 15 drives the fixed gear 17 to rotate, causing the cutting head 18 to rotate on the inner wall of the hollow block 12, allowing the cutting tool to be installed inside the cutting head 18 for rotary cutting. The effect is that releasing the locking block 21 allows the rotating plate 11 to slide on the inner wall of the base plate 5. During use, the angle of the cutting head 18 can be adjusted for precise cutting. When other styles of pipe beveling are required, the cylindrical cutting head 29 can be installed on the inner wall of the cutting head 18 to achieve the effect of cutting different styles of pipe beveling. The cutting head 18 can achieve beveling cuts of various shapes and angles to meet different welding processes and engineering requirements. Furthermore, the first scale 20 ensures that the cut beveling angle is highly consistent with the design requirements, with the error controlled within a very small range, providing a high-precision beveling for subsequent welding work and improving welding quality.

[0029] Reference Figure 1 and Figure 4 The outer wall of the support block 8 is detachably equipped with a support rod 22. The outer wall of the support rod 22 is slidably connected to a first slider 23. The inner wall of the first slider 23 is threadedly connected to a first fixing knob 24. The outer wall of the first fixing knob 24 is rotatably connected to the inner wall of the support rod 22. The outer wall of the first slider 23 is rotatably connected to a second scale 25. The inner wall of the second scale 25 is rotatably connected to a second fixing knob 26. The outer wall of the second fixing knob 26 is threadedly connected to a support column 27. The outer wall of the support rod 22 is slidably connected to a support leg 28.

[0030] Specifically, the support rod 22 installed on the outer wall of the support block 8 allows the first slider 23 and the support leg 28 to slide on the outer wall of the support rod 22, achieving a limiting effect. The first fixing knob 24 fixes the first slider 23 and the support leg 28 to the outer wall of the support rod 22, enabling quick position adjustment and convenient fixation of different types of pipes. The second scale 25 and the support column 27 rotate on the outer wall of the first slider 23, allowing the support column 27 to be replaced during use to fix pipes of different diameters. Adjusting the second scale 25 can stabilize pipes at different cutting angles. Adjusting the first slider 23 and the support leg 28 can support the pipe. The support column 27 can stabilize and support the pipe from multiple directions, effectively reducing pipe vibration and shaking, making the cutting process more stable, and keeping the cut surface flat, thus avoiding defects such as unevenness, wavy or serrated surfaces, and improving the quality of the cut surface.

[0031] Working principle: When the beveling machine is needed, after adjusting the first slider 23 and support leg 28 to the appropriate position using the first fixing knob 24, the second scale 25 and the first slider 23 are adjusted so that the support column 27 can stabilize and support the pipe from multiple directions, effectively reducing the vibration and shaking of the pipe, making the cutting process more stable, and keeping the cut surface flat, thus avoiding defects such as unevenness, wavy or serrated edges, and improving the quality of the cut surface. By pressing the pedal 1, the connecting rod 2 drives the rotating block 6 to rotate on the inner wall of the base plate 5. The connecting rod 2 drives the push block 7 to slide, connecting the clamping block 10 and the support block 8 via the guide rod 9. The push block 7 slides against the outer wall of the guide rod 9, achieving a limiting effect. The push block 7 pushes the pipe to slide onto the outer wall of the clamping block 10, providing a quick clamping effect during use. After the pipe is processed, releasing the pedal 1 allows the spring 4 on the lower surface of the base plate 5 to pull the fixing ring 3, causing the fixing ring 3 to automatically reset the connecting rod 2. The clamping block 10 precisely fixes the pipe in the required position, ensuring the pipe's axis aligns with the beveling machine's cutting tool or cutting edge. The device maintains accurate relative positional relationships, ensuring that the dimensional accuracy of the bevel, such as angle, depth, and width, meets design requirements and welding process standards. When cutting different types of pipes, rotating the locking block 21 allows the first scale 20 fixed to the rotating plate 11 to rotate on the inner wall of the base plate 5, achieving multi-angle adjustment. After adjusting to the appropriate angle, rotating the locking block 21 fixes the rotating plate 11, and then the cutting tool is installed into the cutting head 18. Starting the motor 13 causes the drive gear 14 to drive the transmission gear 15 to rotate, thus driving the transmission gear 15 to rotate... Rotating rod 16 achieves a linkage effect, driving fixed gear 17 to rotate via transmission gear 15, which in turn drives cutting head 18 to rotate. When cutting other types of pipe bevels, cylindrical cutting head 29 can be installed on the inner wall of cutting head 18. Pushing handle 19 allows hollow block 12 to slide on the upper surface of rotating plate 11, achieving uniform grinding of pipe bevel surface and avoiding local over-grinding or unevenness, thus ensuring the flatness and consistency of pipe bevels, and achieving the effect of producing different types of pipe bevels.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
