External burr scraping system and its scraping method

Abstract

The invention discloses an external burr scraping system and a scraping method thereof, which includes a frame, a support roller, a workbench, a motor, a scraper frame, a scraping device and an end seat of the scraper frame; the scraping device includes a base body, a main scraper, an auxiliary scraper, Industrial cameras and telescopic columns; the same number of scraping devices are placed on both sides of the welded pipe, and the scraping depth of each group of scraping devices is set according to the pipe diameter and production standards of the welded pipe. After the main scraper is scraped, the industrial camera takes a picture of the height of the outer burr And transmit it to the computer, through the analysis of the computer to judge whether the auxiliary scraper needs to be supplemented with scraping and the scraping depth of the supplementary scraping, each next set of scraping devices is set to a smaller and smaller scraping depth in turn and repeats the above operations, so as to realize the spiral The step-by-step and precise scraping of the outer burr of the submerged arc welded pipe increases the surface finish of the welded pipe and improves the use effect and service life of the welded pipe.

Description

technical field [0001] The invention belongs to the technical field of welded pipe production, in particular to an outer burr scraping system and a scraping method thereof. Background technique [0002] The spiral submerged arc welded pipe is a spiral seam metal pipe made by bending the strip steel in a spiral shape and welding with the submerged arc welding process. The produced spiral submerged arc welded pipe has excellent weldability, crack resistance, impact toughness and fatigue Strength and plastic deformation ability are superior to longitudinal welded pipes; currently widely used in water supply engineering, petrochemical industry, urban construction and other fields, for liquid transportation or as structural parts, and with the increase of the gap between the supply and demand of natural gas in my country , the construction of the West-East Natural Gas Pipeline puts forward higher requirements on the quality and life of the welded pipe. Therefore, it is very importa...

AI Technical Summary

Problems solved by technology

[0003] During the welding process of the spiral submerged arc welded pipe, the welded pipe moves linearly and rotates at the same time, forming a helical outer burr, which greatly reduces the smoothness of the outer surface of the welded pipe; at the same time, stress concentration is easily generated at the outer burr, resulting in the welded pipe Damage and liquid leakage occur during use, thereby reducing the stability and service life of the welded pipe; At present, many companies are still using manual scrapers to remove the outer burrs of the welded pipe, which is not only labor-intensive, but also easy to remove. Scraping and deep scraping will cause damage to the outer surface of the welded pipe, which will greatly affect the use effect of the welded pipe and reduce the service life of the welded pipe
