Description

Technical Field

[0001] The invention relates to the technical field of pipeline beveling machines, and in particular to a pipeline beveling machine with an adjustable processing mode. Background Art

[0002] Before welding, the fracture of the pipe needs to be processed. At this time, a pipe beveling machine is usually used to process the front end face of the pipe. Traditionally, the pipe end face processing is done by flame cutting, polishing with a grinder, and other operations. The bevel angles obtained by these methods are not standardized, the slopes are rough, and the working noise is loud. The pipe beveling machine is easy to operate, with standard angles and smooth cuts. Therefore, the pipe beveling machine is now mostly used for pipe beveling. The pipe beveling machine can process pipes made of various materials such as cast iron, stainless steel, bearing steel, and structural steel.

[0003] In order to cope with pipes of various different diameters, there are also various pipe beveling machines, such as internal expansion pipe beveling machines and external clamp pipe beveling machines. They are beveling machines that process pipes by fixing them inside and outside the pipe respectively. For pipes with too large diameters, it is more convenient to process the pipes through the inside of the pipe, and for pipes with smaller diameters, it is more convenient to process the pipes through the outside of the pipe. At the same time, when processing the pipes on the outside of the pipe, the pipe beveling machine can also be used to cut the pipes. In actual production and use, when a large number of pipes are processed, if there are pipes of different diameters, it is necessary to frequently move the pipes of different diameters to the corresponding pipe beveling machines for processing. Multiple pipe beveling machines take up more space, and the transportation and classification of pipes are also more labor-intensive, resulting in low processing efficiency of pipe beveling.
