Steel pipe surface polishing and grinding device

Abstract

The invention discloses a steel pipe surface polishing and grinding device. The steel pipe surface polishing and grinding device comprises a rack composed of a cross beam and supporting feet fixed tothe bottoms of the left side and the right side of the cross beam, a sliding groove is formed in the end face of the bottom of the cross beam, and a first threaded rod arranged in a left-right extending mode is arranged in the sliding groove; a sliding block is connected into the first threaded rod in a threaded fit mode, grinding assemblies are arranged at the bottom of the sliding block, a groove is formed in the front end of each grinding assembly, and first sliding cavities are symmetrically formed in the positions, on the upper sides and the lower sides of the grooves, of the grinding assemblies correspondingly; the sides, away from the grooves, of the first sliding cavities are provided with second sliding cavities which are formed in the mode of extending towards the right side, andthe first sliding cavities communicate with the second sliding cavities; second threaded rods arranged in a left-right extending mode are arranged in the second sliding cavities, and pushing pieces are connected to the second threaded rods in a threaded fit mode; limiting blocks are arranged on the sides, close to the grooves, of the inner walls of the right sides of the first sliding cavities; and lifting sliding blocks are connected into the first sliding cavities in a sliding fit mode. According to the steel pipe surface polishing and grinding device, the structure is simple, mounting anddismounting are convenient, the grinding efficiency is high, the grinding work for steel pipes with different diameters can be met, and the environmental protection effect is good.

Description

technical field [0001] The invention relates to the technical field of steel pipe surface polishing, in particular to a steel pipe surface polishing device. Background technique [0002] Before production, steel pipe blanks are inevitably corroded by moisture in the air to produce rust, which is difficult to remove during processing, so generally processed steel pipes still need to be derusted. In the prior art, workers generally use The hand-held cutting machine is equipped with grinding discs for rust removal and polishing. When processing grinding, the intensity of manual labor is high, and the contact between the grinding disc and the steel pipe cannot be accurately controlled, which may cause excessive grinding or no grinding at all. For example, once the grinding is too deep, the surface of the steel pipe will be damaged, causing unevenness and forming waste. If the grinding is too shallow, the rust cannot be removed, and the processing is more difficult. In addition, ...

[0002] Before production, steel pipe blanks are inevitably corroded by moisture in the air to produce rust, which is difficult to remove during processing, so generally processed steel pipes still need to be derusted. In the prior art, workers generally use The hand-held cutting machine is equipped with grinding discs for rust removal and polishing. When processing grinding, the intensity of manual labor is high, and the contact between the grinding disc and the steel pipe cannot be accurately controlled, which may cause excessive grinding or no grinding at all. For example, once the grinding is too deep, the surface of the steel pipe will be damaged, causing unevenness and forming waste. If the grinding is too shallow, the rust cannot be removed, and the processing is more difficult. In addition, there is also polishing and grinding by automatic grinding equipment. The existing automatic polishing and grinding The machines are all single grinding heads, the grinding efficiency is low, and the grinding accuracy is poor
