Description

Technical Field

[0001] The utility model relates to the technical field of pipeline processing, and particularly relates to a processing device for a pipeline end face. Background Art

[0002] At present, during the hot melt butt joint of drainage pipelines, especially at the hot melt butt joint of PE pipelines, due to the material being heated and melted and being extruded by an external force, U-shaped flanges will be formed on both the inside and outside of the pipeline. When the pipeline is used for fluid transportation, the internal flange of the pipeline has an obstructive effect and reduces the drainage flow rate during pipeline drainage. The seamless butt joint process can effectively reduce the size of the internal flange of the pipeline during hot melt butt joint and increase the drainage flow rate of the pipeline. This process requires processing a corresponding specification annular groove on the inner wall of the pipeline according to the diameter of the pipeline. Currently, existing hot melt butt joint equipment, its turning and milling mechanism can only perform planar milling on the pipeline end face and cannot process grooves on the pipeline end face; currently, the traditional turning processing method requires the use of a turning lathe for processing. Traditional lathes are large in size, heavy in weight, inconvenient to move, not suitable for on-site operation at the construction site, and the operation steps are cumbersome. It requires personnel with a certain professional skill foundation to operate. Moreover, traditional lathes are only suitable for pipelines with a short length and have certain limitations on the length of the processed pipeline.

[0003] The patent publication number is CN117259804A, which discloses a tool structure for turning a groove hole on the end face of a pipe. The positioning module of this structure can extend into the pipe to fix the pipe and meet the requirement of grooving the pipe. This patented product has some disadvantages compared with this product: 1. This patented product supports the pipe through the inner wall of the pipe, which easily causes deformation of the inner wall of the pipe due to force. 2. The size of the positioning ring of this patented product is single and fixed, which is inconvenient for processing when dealing with pipes of different specifications. 3. The tool of this patented product is fixed separately. When the processed material is uneven and the force is unstable, there is a risk of tool breakage. 4. This patented product only improves the cutting tool structure. Content of the Utility Model
