Steel pipe polishing device

Abstract

The invention provides a steel pipe polishing device. The steel pipe polishing device is characterized in that two supporting plates are symmetrically hinged to each of the left side and the right side of the upper end of a base; every two supporting plates which are symmetrical along the central axis of the base form a V-shaped supporting structure; a roller is mounted on the inner side face of each supporting plate; the four supporting plates are each hinged to the base through a hydraulic cylinder; a polishing wheel mounted on the base is arranged in the symmetrical axis position of the V-shaped supporting structure located at one end of the base; and a belt wheel on a polishing wheel mounting shaft is connected with a belt wheel of an output shaft of a polishing motor through a transmission belt, and the polishing motor is mounted on the base. A polishing steel pipe can be firmly supported through the V-shaped supporting frames; the steel pipes of different pipe diameters can be polished through extending and retracting of piston rods of the hydraulic cylinders; and a lifting dust suction cover and a negative-pressure fan can suck iron scraps in the polishing process and meanwhile take the protection effect, so that using is safe and convenient, and the influence of polishing on the air quality is reduced.

Description

technical field [0001] The invention belongs to the technical field of steel pipe processing, and in particular relates to a steel pipe grinding device. Background technique [0002] The grinding machine is a machine used to grind welded steel pipes. Steel pipes include seamless steel pipes and welded steel pipes. The cost of seamless steel pipes is higher than that of welded steel pipes. Generally, the welds of steel pipes need to be polished, and the surface of steel pipes is corroded with the air. Use The overall grinding process is required before the steel pipe is polished. At present, the steel pipe is generally polished by hand-held electric tools. This grinding method is inefficient, poor in safety, and the polished surface quality is poor. [0003] At present, the steel pipe automatic grinding equipment on the market is expensive and has a complex structure. At the same time, the processing of these steel pipes cannot meet the grinding treatment of different sizes o...

[0002] The grinding machine is a machine used to grind welded steel pipes. Steel pipes include seamless steel pipes and welded steel pipes. The cost of seamless steel pipes is higher than that of welded steel pipes. Generally, the welds of steel pipes need to be polished, and the surface of steel pipes is corroded with the air. Use The overall grinding process is required before the steel pipe is polished. At present, the steel pipe is generally polished with hand-held electric tools. This grinding method is inefficient, and the safety is poor, and the polished surface quality is poor.

[0003] At present, the steel pipe automatic grinding equipment on the market is expensive and has a complex structure. At the same time, the processing of these steel pipes cannot meet the grinding treatment of different sizes of pipe diameters or the range of pipe diameters that can be polished is small, resulting in poor adaptability of the grinding equipment. And in Flying dust, fine iron filings, etc. will be generated during the grinding process to pollute the air environment
