Outer welding rib removing device with double scrapers

Abstract

The invention relates to a welding rib removing device, in particular to a device used in cooperation with high-frequency welding equipment and used for removing an outer welding rib of a high-frequency welding pipe blank. The device comprises a base. A supporting plate is arranged on the base. Tool rests are arranged on one side of the supporting plate. A scraper is arranged on one side of each tool rest. The scraper faces of the scrapers are perpendicular to the supporting plate. The lower ends of the scrapers stretch out from the bottoms of the tool rests, and cutting edges are arranged at the bottoms of the scrapers. The outer welding rib removing device is characterized in that the two tool rests are arranged and are the same in height, the two tool rests are arranged side by side and are provided with the scrapers, and the cutting edges are arranged at the bottoms of the scrapers; a supporting device is arranged below the two scrapers and comprises a wheel frame, and air cylinders are arranged between the bottom of the wheel frame and the base; and wheels are arranged on the top of the wheel frame, an annular groove formed in the circumferential direction of the rolling face of each wheel is formed in the rolling face of the wheel, and the section of each annular groove is in an arc shape. The outer welding rib removing device is used for scraping away small-caliber or thin-wall pipe blanks, the phenomenon of scraper jumping is avoided, and the problems that the pipe blanks are extruded to be damaged and welding rib scraping is not uniform can be solved.

Description

technical field [0001] The invention relates to a welding rib removal device, in particular to a device used in conjunction with high-frequency welding equipment for removing the outer welding ribs of a high-frequency welded pipe billet. Background technique [0002] It is known in the machinery industry that during the production process of high-frequency welded pipes, the raw materials need to be crimped to form a tube blank. This tube blank has a gap running through its longitudinal direction, and the gap is filled and eliminated by high-frequency welding equipment. , the welded tube blank needs to go through the outer welding rib removal device to remove the outer welding rib. [0003] At present, the external welding rib removal device used in the industry includes a base, a support plate arranged vertically on the base, a knife rest is fixed on one side of the support plate, and a scraper is arranged on one side of the knife rest. The blade surface is perpendicular to...

Problems solved by technology

[0004] The problem to be solved by the present invention is to provide a device for removing external welding ribs for high-frequency steel pipes. Using this device to scrape off small-diameter or thin-walled tube blanks will not cause knife jumping, and can avoid tube blanks being squeezed and welding ribs. Problems such as uneven scraping
