Environment-friendly efficient steel pipe surface finishing and polishing device

Abstract

The invention discloses an environment-friendly efficient steel pipe surface finishing and polishing device. The device comprises a machine frame. The machine frame is composed of a cross beam and supporting feet fixed to the 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. A first thread rod extending left and right is arranged in the sliding groove. A sliding block is connected to the interior of the first thread rod in a thread fit mode. A polishing assembly is arranged at the bottom of the sliding block. A groove is formed in the front end of the polishing assembly. First sliding cavities are symmetrically formed in the portions, on the upper side and the lower side of the groove, of the polishing assembly. The side, away from the groove, of each first sliding cavity is provided with a second sliding cavity extending towards the right side in a communicating mode. Second thread rods extending left and right are arranged in the second sliding cavities. Pushing-pressing parts are connected to the second thread rods in a thread fit mode. The sides, close to the groove, of the inner walls on the right sides of the first sliding cavities are provided with limiting blocks. Lifting sliding blocks are connected to the interiors of the first sliding cavities in a sliding fit mode. The environment-friendly efficient steel pipe surface finishing and polishing device is simple in structure, convenient to mount and demount, high in polishing efficiency, capable of polishing steel pipes with different diameters and good in environmental protection effect.

Description

technical field [0001] The invention relates to the technical field of steel pipe surface polishing, in particular to an environment-friendly and efficient 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 process...

[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
