Especially when pipe dimensions vary considerably, drawing accurate intersection lines becomes a difficult task, requiring operators to rely on manual measurement and marking, which is prone to errors. Furthermore, traditional equipment and tools are often not well-suited to the requirements of pipe intersection lines of different specifications and angles, resulting in limited tool applicability and low production efficiency.

The adjustable angle dial 102, diameter positioning pin 301, and sliding block 203 are suitable for drawing intersection lines on reducing tee mains, solving the complex processing problems of reducing pipe diameters.

[0053] The working method of the pipe intersection line marking device provided in this embodiment of the utility model is as follows:

[0054] First, set the required intersection angle using the angle scale on the angle dial 102. Ensure the accuracy of the angle using the angle positioning block 202. The scale on the angle dial 102 precisely determines the angle. Second, adjust the pipe diameter using the sliding block 203 and the diameter positioning pin 301 on the swing arm 3 to match the requirements of the marking tool. The length scale on the swing arm 3 helps to accurately measure the pipe diameter. Then, install the ejector pin 201 at one end of the spindle tube 2. After loosening the adjusting bolt, the extension length of the ejector pin 201 can be extended or shortened to achieve the required pipe size for marking. Next, connect the marking tube 4 to the diameter positioning pin 301 and install the marking pen 401 at one end of the marking tube 4. After determining the pipe intersection position using the ejector pin 201, the marking pen 401 can draw a precise intersection line along the pipe surface. Finally, fix and tighten all connecting parts 101 with bolts to ensure stability of each component during use. After use, each component can be disassembled and reconfigured as needed for easy subsequent use and maintenance.

[0055] Taking a reducing tee main pipe as an example, when using the pipe intersection line drawing tool provided in this utility model embodiment to draw the intersection line, the operation steps are as follows: Rotate the angle plate 102 according to the angle of the tee pipe to be processed, ensuring that the drawing angle of the intersection line is consistent with the actual requirements of the pipe; adjust the diameter positioning column 301 on the swing arm 3 according to the different diameters of the tee pipe, so that it fits the diameter of the tee pipe; adjust the extension length of the ejector pin 201 by adjusting the bolt according to the thickness and shape of the pipe, ensuring that the ejector pin 201 can be correctly positioned and the intersection line drawn; use the drawing tube 4 and the drawing pen 401 to accurately draw the intersection line on the pipe, ensuring that the pipe intersection line meets the design requirements.

[0056] In summary, the pipe intersection line marking device provided by this utility model, through the design of an adjustable swing arm 3 and a base plate 1, can handle pipes of different specifications and angles, meeting the production needs of multi-port pipes with varying diameters, and has wide applicability. By using a precise angle plate 102 and a length scale, and equipped with a sliding block 203 and a diameter positioning post 301, it can effectively reduce measurement errors caused by manual operation, thereby ensuring the accuracy of pipe intersection lines. By improving the overall efficiency of pipe intersection line layout, it can be widely applied to the production needs of pipes of different specifications and angles.
