Abstract

The invention discloses a scraper for the inner weld seam of a spiral steel pipe, which includes a driving rod, a rotating column, a blade, a cooling pipe and a plug; the rear end of the driving rod is connected to the front end of the rotating column, and the driving rod is connected to the The rotating column is coaxially arranged, and several blades are evenly arranged on the outer peripheral surface of the rotating column, and the blades are parallel to the central axis of the rotating column; a liquid storage cavity is arranged in the rotating column, so that The rear end of the rotating column is provided with an opening communicating with the liquid storage cavity, and the plug is fixed in the opening through threaded connection; the two ends of the cooling pipe are open, and one end of the cooling pipe is fixed on the On the outer peripheral surface of the rotating column, the cooling pipe communicates with the liquid storage cavity. The invention can efficiently remove the welding slag on the inner surface of the spiral steel pipe, and has high welding slag removal rate, low noise and long service life.

Description

technical field [0001] The invention relates to a cutting tool, in particular to a cutting tool for welding seam processing. Background technique [0002] Spiral steel pipe is a spiral seam steel pipe made of strip steel coil as raw material, extruded at regular temperature, and welded by automatic double-wire double-sided submerged arc welding process. There are spiral welds on the spiral steel pipe. During the welding process, welding slag will be formed at the weld seam on the inner surface of the spiral steel pipe. Before the spiral steel pipe is put into use, the welding slag on the inner surface needs to be removed. At present, the welding slag is dropped by the vibration of the spiral steel pipe itself by manual knocking. This method has the problems of low efficiency and high noise, and also has the problem that some welding slag cannot be cleaned. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the...
