Description

Technical Field

[0001] The utility model relates to the technical field of anti-corrosion pipe processing equipment, in particular to a 3PE anti-corrosion pipe end trimming production equipment. Background Technique

[0002] The base materials of 3PE anti-corrosion steel pipes include seamless steel pipes, spiral steel pipes and straight-seam steel pipes. The three-layer structure of polyethylene (3PE) anti-corrosion coating has been widely used in the petroleum pipeline industry due to its good corrosion resistance, water vapor permeability resistance and mechanical properties, etc. The anti-corrosion layer of 3PE anti-corrosion steel pipes is crucial for the service life of buried pipelines; after the 3PE anti-corrosion steel pipes are processed, it is necessary to process the pipe ends of the pipelines to process the anti-corrosion layer at the pipe end part into a sloping bevel surface, so as to facilitate the butt joint of two pipelines during subsequent installation construction and the anti-corrosion treatment after butt joint. At present, the commonly used method at home and abroad is to use a high-speed rotating wire brush to polish the anti-corrosion layer at the pipe end. However, for the anti-corrosion pipes produced by many anti-corrosion manufacturers, the polishing of the pipe ends is very irregular and needs to be re-polished, which not only affects the production progress but also increases the construction cost.

[0003] In view of the above existing technical problems, the utility model patent with the publication number of CN221494397U discloses an automatic cutting device for grooved anti-corrosion steel pipes. The automatic positioning device drives the beveling machine to move forward. After automatically positioning the steel pipe nozzle through the infrared induction device, the supporting wheel fixes the nozzle. Then, through the PLC control program, the first cylinder is controlled to drive the white steel knife to move. The movement of the white steel knife drives the cutting tool slide rail to rise along the cutting tool slideway. When the white steel knife reaches the position of the steel pipe and the distance between the white steel knife and the supporting wheel is appropriate, the white steel knife is fixed under the action of the second sensor. After receiving the positioning signal of the white steel knife, the pipe rotating machine is automatically started, and the anti-corrosion layer on the surface of the anti-corrosion steel pipe is cut through the fixation of the supporting wheel. After the cutting is completed, the wire brush is raised by the second cylinder to automatically grind the cutting surface.

[0004] However, in the actual application process of the above technical solution, during the grinding process, a large amount of debris and fumes will be generated. The accumulation of a large amount of debris around the equipment will affect the normal heat dissipation of the equipment, affect the normal operation of the equipment, and at the same time will cause the production workshop environment to be dirty and messy; while the fumes will cause the production workshop to be filled with pungent odors, pollute the working environment of the production workshop, and affect the physical health of workers.
