Automatic grinding rust removal device for steel pipe outer wall

Abstract

The invention relates to the technical field of steel pipe machining, in particular to an automatic grinding rust removal device for a steel pipe outer wall. The device comprises a base, a grinding mechanism and a fixing mechanism. Two side plates are symmetrically and fixedly mounted on the left side and the right side of the base, a top plate is fixedly mounted on the tops of the side plates, afirst screw rod is arranged below the top plate, a first screw sleeve is in threaded connection to the first screw rod, the grinding mechanism is fixedly mounted below the first screw sleeve through amounting plate, the interior of the grinding mechanism is rotatably provided with a rotating sleeve, the rotating sleeve is of a sleeve structure with openings in the two ends, the outer side of therotating sleeve is fixedly provided with a gear ring, a round gear is rotatably mounted on the grinding mechanism, and the round gear is engaged with the gear ring. The rotating sleeve is arranged onthe outer side of a steel pipe in a sleeving manner, the first screw sleeve which continuously moves left and right drives the rotating sleeve to move left and right on the outer side of the steel pipe, a grinding roller makes sufficient contact with all portions of the surface of the steel pipe, and the steel pipe can be effectively ground.

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.

AI Technical Summary

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
