Description

Technical Field

[0001] This utility model relates to the field of beveling machine technology, specifically a beveling machine for pipe processing. Background Technology

[0002] In pipeline system installation, pressure vessel manufacturing, and various steel structure projects, specific angles and shapes of bevels must be machined at the ends of pipes to ensure welding quality. High-quality bevels are a key prerequisite for ensuring weld penetration, improving connection strength, and enhancing sealing performance.

[0003] In existing processes, the beveling of pipe ends typically involves a two-stage process: rough cutting at a fixed angle followed by fine grinding with abrasive belts. This method heavily relies on the operator's experience and feel, requiring repeated measurements, comparisons, and corrections during the grinding process to achieve the target angle. This not only leads to low processing efficiency but also makes it difficult to guarantee the consistency of the bevel angle, resulting in significant processing errors and insufficient quality stability. Utility Model Content

[0006] A rotating plate is rotatably installed inside the workbench, and a base plate is fixedly installed on the top of the rotating plate. A support plate is detachably installed on the top of the base plate by bolts, and the base plate is slidably installed on the top of the workbench by an adjustment assembly.

[0007] The base plate has a first threaded rod rotatably mounted inside it. One end of the first threaded rod is fixedly connected to a handwheel. Two movable plates are engaged with the outer wall of the first threaded rod. Fixed plates are slidably mounted on the top of each of the two movable plates.

[0012] As a further preferred embodiment of this technical solution, a connecting shaft is fixedly connected to one side of the fixing plate, and the connecting shaft is slidably mounted on the side wall of the support plate.

[0013] This utility model provides a beveling machine for pipe processing, which has the following beneficial effects:

[0014] (1) This utility model enables the bevel of the pipe to be formed in one step by adjusting the angle first and then processing, which helps to improve processing efficiency.

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0022] This utility model provides a technical solution as follows: Figures 1 to 4As shown, in this embodiment, a beveling machine for pipe processing includes a worktable 1, a transmission box 2 for mounting a power assembly, and a cutting head 5 for cutting pipes.

[0023] A rotating plate 13 is rotatably installed inside the workbench 1. A base plate 8 is fixedly installed on the top of the rotating plate 13. A support plate 7 is detachably installed on the top of the base plate 8 by bolts. The base plate 8 is slidably installed on the top of the workbench 1 by an adjustment assembly.

[0024] The base plate 8 has a first threaded rod 11 rotatably mounted inside it. One end of the first threaded rod 11 is fixedly connected to a handwheel 12. Two movable plates 10 are engaged on the outer wall of the first threaded rod 11. Fixed plates 9 are slidably mounted on the top of each of the two movable plates 10. The two fixed plates 9 are symmetrically distributed.

[0025] The power unit consists of a conventional motor and drive shaft;

[0026] The outer wall of the first threaded rod 11 is provided with two threads, which respectively engage with the two movable plates 10, and the two threads are arranged in opposite directions.

[0027] During operation, the pipe is first placed on top of the support plate 7, positioning it between the two fixed plates 9. Then, the position is adjusted, and the first threaded rod 11 is rotated by turning the handwheel 12. The rotation of the first threaded rod 11 causes the two moving plates 10 to move closer to each other. The movement of the moving plates 10 causes the fixed plates 9 to move, so that the two fixed plates 9 move relative to each other to fix the pipe.

[0028] Then, by rotating the base plate 8, the pipe moves around the end of the rotating plate 13 as the center, and the processing angle is adjusted.

[0029] Finally, the cutting head 5 is driven to rotate by the power assembly, and the transmission box 2 is moved toward one end of the tube to process it.

[0030] The above processing method, which adjusts the angle before processing, allows the pipe bevel to be formed in one step, which helps to improve processing efficiency. Especially when processing in batches, it can ensure the consistency of the bevel angle of each pipe and ensure processing quality.

[0031] like Figures 1 to 3 As shown, a protective plate 6 is fixedly connected to one side of the transmission box 2, and the protective plate 6 is slidably installed on the top of the workbench 1.

[0032] The top of the workbench 1 is provided with a slide groove 16 for the transmission box 2 to slide. The protective plate 6 is located on top of the slide groove 16 to protect it and prevent debris from splashing into the slide groove 16 during cutting operations and affecting the movement of the transmission box 2.

[0033] like Figure 1 and Figure 2As shown, an angle plate 14 is provided at one end of the base plate 8, and the angle plate 14 is fixedly installed on the worktable 1.

[0034] The operator does not need to use an additional angle ruler or electronic measuring instrument. While clamping the pipe, their field of vision is directly facing the scale plate, and the current angle value can be read directly, providing a reliable angle reference and greatly improving the efficiency and convenience of operation.

[0035] like Figures 1 to 4 As shown, the adjustment assembly includes a slider 15 fixedly installed at the bottom of the base plate 8, and the slider 15 is slidably installed on the inner wall of the slide groove 16, which is located at the top of the worktable 1.

[0036] The bottom of the slider 15 is slidably connected to an adjustment plate 17, and the inner wall of the adjustment plate 17 is threaded with a second threaded rod 18, and a second motor 19 is installed at one end of the second threaded rod 18.

[0037] When adjusting the processing angle of the pipe, the second threaded rod 18 is driven to rotate by the second motor 19. The rotation of the second threaded rod 18 drives the adjustment plate 17 to move. The movement of the adjustment plate 17 drives the slider 15 to move. The movement of the slider 15 drives the base plate 8 to rotate around one end of the rotating plate 13 to adjust the processing angle of the pipe, thus realizing the digital and programmed precise control of the bevel angle.

[0038] like Figure 1 , Figure 2 and Figure 4 As shown, a connecting shaft 20 is fixedly connected to one side of the fixed plate 9, and the connecting shaft 20 is slidably installed on the side wall of the support plate 7.

[0039] When processing pipes of different diameters, the height between the support plate 7 and the base plate 8 can be adjusted using bolts. The support plate 7, via the connecting shaft 20, drives the fixed plate 9 to slide, allowing the fixed plate 9 to move on top of the moving plate 10. Simultaneously, the height of the fixing structure is adjusted to ensure that the rotation axis of the pipe remains constant in the vertical direction, thus completely avoiding pipe tilting and axis misalignment caused by inconsistent support heights at both ends. This ensures absolute concentricity of the processing datum and improves processing accuracy.

[0040] This utility model provides a beveling machine for pipe processing, the specific working principle of which is as follows:

[0041] During operation, the pipe is first placed on top of the support plate 7, positioning it between the two fixed plates 9. Then, the position is adjusted, and the first threaded rod 11 is rotated by turning the handwheel 12. The rotation of the first threaded rod 11 causes the two moving plates 10 to move closer to each other. The movement of the moving plates 10 causes the fixed plates 9 to move, so that the two fixed plates 9 move relative to each other to fix the pipe.

[0042] Then, the second threaded rod 18 is driven to rotate by the second motor 19. The rotation of the second threaded rod 18 causes the adjusting plate 17 to move. The movement of the adjusting plate 17 causes the slider 15 to move. The movement of the slider 15 causes the base plate 8 to rotate around one end of the rotating plate 13 to adjust the processing angle of the pipe.

[0043] Finally, the cutting head 5 is driven to rotate by the power unit, and the transmission box 2 is moved toward one end of the tube for processing.

[0044] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
