Rotary feeding device of round pipe

Abstract

The invention discloses a rotary feeding device of a round pipe. The rotary feeding device comprises a frame, wherein the frame is symmetrically provided with multiple guide rollers, a rack is supported on the multiple guide roller, the frame is provided with a power input device, a power input shaft of the power input device is provided with a gear engaged with the rack, the rack is symmetrically provided with multiple drive shafts, a cylindrical gear is arranged on one end of each drive shaft, the cylindrical gear is engaged with a fixed gear fixed on the frame, a first bevel gear is arranged on the other end of each drive shaft, and each first bevel gear is engaged with a group of feeding wheel sets. The device is simply structured and convenient to use, when shot blasting, sand blasting and paint coating treatments are carried out, the round pipe is rotated to work and the axial feeding motion is carried out simultaneously, so that the grinding material is ejected for coated uniformly and free of dead angles.

Description

technical field [0001] The invention relates to a circular pipe rotary feeding device. Background technique [0002] Steel pipes are widely used in petrochemical, steel, urban central heating, water supply and drainage industries. In order to improve the service life of pipes, the inner and outer walls of steel pipes need surface strengthening, rust removal, painting and other treatments. Surface shot blasting and sand blasting can strengthen the surface, improve fatigue strength and corrosion resistance, and also increase the surface area and increase the bonding force between the paint surface and the metal surface. When the steel pipe is subjected to shot blasting, sandblasting and painting, it is required that the pipe is rotated and moved axially at the same time, so that the abrasive spray or paint is uniform without dead ends. At present, steel pipe shot blasting, sandblasting and other equipment generally place the steel pipe on the roller table for linear input, an...

AI Technical Summary

Problems solved by technology

At present, steel pipe shot blasting, sandblasting and other equipment generally place the steel pipe on the roller table for linear input, and the steel pipe does not rotate. To spray the bottom of the steel pipe, it is necessary to add a shot blaster or sandblasting port at the lower part of the roller table. The angles are different, the injection density and injection time of each part of the steel pipe are different, the surface of the steel pipe is not uniformly sprayed, some parts are not sufficiently treated, and there will be obvious transition lines at dead corners, which also directly affect the quality of surface strengthening.

Due to the addition of shot blasting machines, etc., the cost of equipment has also been greatly increased.
