Problems solved by technology

The existing grinding devices all use the grinding wheel for grinding work. At the same time, due to the different thickness of the weld seam, some places where the weld seam is thin cannot be polished, the grinding effect is poor, and the product quality is reduced. Processing of longitudinal welded pipes of one length, the scope of use is small

Abstract

The invention discloses a polishing device suitable for double-side submerged arc longitudinally welded pipe weld. The polishing device comprises a base, a sliding groove is formed in the surface of the base, a slider is mounted inside the sliding groove in the surface of the base in a matched manner, a chuck mounting seat is fixedly mounted at the upper end of the slider and is of an annular structure, a chuck is mounted on the inner surface of the chuck mounting seat in a matched manner, sliding grooves are uniformly formed in the surface of the chuck, and clamping claws are mounted in the sliding grooves in the surface of the chuck in a matched manner and connected with the chuck through a third electric extensible rod. The chuck is adopted as a clamp, so that the polishing device is suitable for processing pipelines different in diameter; distance among the chucks is adjustable, so that the polishing device is suitable for processing pipelines different in length; a polishing beltis adopted for polishing, so that polishing effect is ensured.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a grinding device suitable for welding seams of double-sided submerged arc longitudinal welded pipes. Background technique [0002] The double-sided submerged arc spiral welded steel pipe sends the strip steel into the welded pipe unit. After being rolled by multiple rollers, the strip steel is gradually rolled up to form a round tube billet with an opening gap. Adjust the reduction of the extrusion roller to make the weld joint The ends are flush. The spiral welded pipe is formed by spirally forming the raw material strip steel through a forming machine, and then welded by internal and external submerged arc to produce spiral welded pipes of different specifications. The production process of double-sided submerged arc spiral welded steel pipe is simple, the operating cost is low, and it has the advantage of low-cost operation. It has price advantages in the marke...
