An automatic grinding and derusting device for the outer wall of a steel pipe

Abstract

The invention relates to the technical field of steel pipe processing, in particular to an automatic grinding and derusting device for the outer wall of a steel pipe, including a base, a grinding mechanism and a fixing mechanism; two side plates are symmetrically fixed on the left and right sides of the base, and the top of the side plate is fixed A top plate is installed, the bottom of the top plate is provided with a first screw rod, and the first screw rod is threadedly connected with a first screw sleeve; the grinding mechanism is fixedly installed under the first screw sleeve through the mounting plate; the internal rotation of the grinding mechanism A rotating sleeve is installed, and the rotating sleeve is a sleeve structure with openings at both ends, and a ring gear is fixedly installed on the outside of the rotating sleeve, and a circular gear is also rotated on the grinding mechanism, and the circular gear meshes with the ring gear. The invention sets the rotating sleeve on the outer side of the steel pipe, and drives the rotating sleeve to move left and right on the outer side of the steel pipe through the first threaded sleeve which is constantly moving left and right, so that the grinding roller can fully contact with various parts of the steel pipe surface, effectively grinding the steel pipe .

Description

technical field [0001] The invention relates to the technical field of steel pipe processing, in particular to an automatic grinding and derusting device for the outer wall of a steel pipe. Background technique [0002] Steel pipes are used to transport fluids and powdery solids, exchange heat, and manufacture mechanical parts and containers. It is also a kind of economical steel. The development of steel pipe production technology began with the rise of the bicycle manufacturing industry, the development of petroleum in the early 19th century, the manufacture of ships, boilers, and aircraft during the two world wars, the manufacture of thermal power boilers after the Second World War, the development of the chemical industry and Drilling, production and transportation of oil and natural gas have strongly promoted the development of steel pipe industry in terms of variety, output and quality.

Problems solved by technology

[0003] During the long-term idle process of the steel pipes in the warehouse, the surface is prone to be affected by moisture to produce rust. When the steel pipes are used, the surface of the steel pipes needs to be derusted. Most of the derusting methods in the prior art are manually completed. For steel pipes with larger diameters, The method of manual rust removal is not only difficult to operate, low in efficiency of rust removal, but also has certain safety hazards
