Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of machining, in particular to a novel multifunctional annular oxide scale cutting tool. BACKGROUND

[0002] Polyethylene (PE) materials are widely used in urban gas pipeline systems due to their excellent chemical stability and mechanical properties, especially in the field of gas pipeline connection technology. Among them, electrofusion connection, as an efficient and reliable connection method, has been widely used. Electrofusion connection technology uses the built-in resistance wire of the electrofusion sleeve to heat the contact part of the PE pipe and the sleeve, and after cooling, a firm bond is formed, thereby achieving high-quality connection. Its operation is simple, and the connection strength is high, making it one of the preferred connection methods in gas pipeline construction.

[0003] However, during the long-term use of PE gas pipelines, due to environmental factors such as sunlight and oxidation, a layer of oxide scale will gradually form on the surface of the pipe. The formation of oxide scale not only weakens the mechanical properties of PE pipe, but also adversely affects the welding quality of the electrofusion welding area. Before electrofusion connection or pipeline repair work is carried out, it is essential to remove the oxide scale on the surface of the pipe, because the presence of oxide scale can significantly reduce the bonding quality of electrofusion welding, and even may result in poor or failed fusion between the electrofusion joint and the pipe, increasing the risk of gas leakage and endangering the safe operation of the gas pipeline network.

[0004] Therefore, before electrofusion welding operation, thorough oxide scale removal treatment must be carried out on the pipe surface at the welding site to ensure high-quality fusion of the welded joint. This process is of great significance to ensure the long-term stable operation of the gas pipeline system, effectively reducing the risk of leakage caused by poor welding quality, and improving the safety and reliability of pipeline operation.

[0005] The existing removal method uses a manual scraper for removal, which is labor-intensive and does not meet the size requirements.

[0006] To solve the above technical problems, a rotating scraper is disclosed in Patent No. CN205219239U, which can be used to remove the outer layer material of the PE pipe to facilitate electrofusion sleeve welding.

[0054] As shown in Figure 4 , the outer support mechanism 5 comprises a limiting groove 51 equidistantly and spacedly provided at the top of the top ring 4, a fastening bolt 52 threadedly connected at the bottom of the inner cavity of the limiting groove 51, a moving plate 53 slidingly connected in the inside of the limiting groove 51, a limiting hole 54 opened at the top of the moving plate 53, the fastening bolt 52 penetrating through the moving plate 53 through the limiting hole 54, and a roller 55 rotatably connected at the inner end of the moving plate 53, so as to conveniently support the outer side of the pipe to assist in placing and deforming.
