Environment-friendly and efficient steel tube surface polishing and grinding device

Abstract

The invention discloses an environment-friendly and efficient steel tube surface polishing and grinding device. The polishing and grinding device includes a cross beam and a rack, wherein the rack iscomposed of supporting feet fixed on the bottom of both left and right sides of the cross beam. The end surface of the bottom of the cross beam is internally provided with a sliding groove. The sliding groove is provided with a first threaded rod arranged in left and right extending mode. The first threaded rod is internally connected with a sliding block in a threaded and matched mode. The bottomof the sliding block is provided with a polishing assembly. The front end of the polishing assembly is internally provided with a groove. Polishing assemblies on the upper and lower sides of the groove are internally provided with first sliding cavities symmetrically. A second sliding cavity arranged in an extending towards the right side mode is arranged on the side, away from the groove, of each first sliding cavity. Each first sliding cavity and the corresponding second sliding cavity communicate with each other. Each second sliding cavity is internally provided with a second threaded rodarranged in left and right extending mode. Each second threaded rod is connected with a pushing piece in a threaded and matched mode. The inner wall, close to the groove, of the right side of each first sliding cavity is provided with a limiting block. Each first sliding cavity is internally and slidably connected with a lifting sliding block in a matched mode. The environment-friendly and efficient steel tube surface polishing and grinding device is simple in structure, convenient to arrange and remove, and high in polishing efficiency; polishing of steel tubes with different diameters can besatisfied; 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 an environmentally 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 pro...

[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
