Description

Technical Field

[0001] The utility model relates to the technical field of pipeline processing, in particular to a building pipeline cutting machine. Background Art

[0002] As an indispensable material in engineering construction, building pipes come in many types to meet various usage requirements. In addition, since the lengths of building pipes required for different scenarios are different, building pipes need to be cut using a cutting machine according to actual on-site needs during installation.

[0003] A search revealed an existing patent (publication number: CN221247108U) that discloses a building pipe cutting machine. During use, the curved plates on either side of the cutting blade are placed against the building pipe to position the cutting blade's cutting angle, keeping the blade perpendicular to the pipe's direction. The cutting is then completed by rotating the pipe or wrapping the cutting blade around it. The cutting surface is perpendicular to the length of the pipe, ensuring that subsequent pipe connections are neat and high-quality, less prone to leaks or poor connection quality. However, during the development of the present invention, the inventors discovered that the prior art suffers from the following problems: The aforementioned cutting machine positions the cutting blade's cutting angle by placing the curved plates against the pipe's surface. In this case, the cutting blade always remains perpendicular to the pipe's direction, keeping the pipe's opening flush and the cutting angle fixed. This makes it difficult to accurately cut the pipe at the designed angle when the pipe needs to be angled, as required by on-site pipe installation. This results in a limited range of applications.

[0004] In view of this, the utility model proposes a building pipe cutting machine to solve this problem. Utility Model Content
