Abstract

The invention relates to a peeling device for once eliminating an oxidizing layer on the outer surface of the end part of pipes, aiming to provide a peeler for qualitatively eliminating the polyethylene pipe oxidizing layer on the outer surface of pipes more convenient and efficient and faster. The peeler for eliminating the polyethylene pipe oxidizing layer comprises a knife tool, which is characterized in that the peeler also comprises an underframe and a fixed bracket; wherein, the fixed bracket comprises an arc slot, the fixed bracket is fixed and connected with the underframe in a detachable way, the underframe is provided with the knife tool and the blade direction of the knife tool parallels the axial direction of the arc slot. The peeler for eliminating the polyethylene pipe oxidizing layer has the advantages that the linear contact between the knife tool and the pipe surface can evenly and effectively eliminate the oxidizing layer on the surface of pipes; the peeling depth canbe adjusted by regulating the screwing depth of a tightening screw and the oxidizing layer can be easily eliminated by manually rotating a spanner; the quality of the pipe surface after being peeledcan be effectively controlled; the peeling device also has the advantages of simple structure, easy production and practicality.

Description

technical field

[0001] The utility model relates to a skin scraping device for removing the oxidized layer on the outer surface of the pipe fitting end at one time. More specifically, the utility model relates to a scraper for scraping the oxide layer on the outer surface of polyethylene pipe fittings during the electrofusion welding process of PE pipes. Background technique

[0002] Electrofusion connection is one of the most commonly used connection methods for polyethylene pipes. During the welding process, the existence of an oxide layer on the outer surface of the pipe will seriously hinder the diffusion of polyethylene polymer chains during the welding process, thereby greatly reducing the strength of the welded joint. Therefore, before electrofusion welding, the oxide skin in the welding zone on the surface of the pipe must be scraped off.

[0003] At present, flat scrapers are generally used in the application of PE pipe electric fusion welding engineering, see poly...
