Steel pipe derusting machine

Abstract

The invention relates to a steel pipe derusting machine. The machine comprises a base, wherein a gantry bracket is fixedly arranged on the base; upright posts are arranged on the gantry bracket; wall plates are sleeved on the upright posts and can vertically slide; lifting adjustment speed reducing motors and lifting screw rods are arranged above the gantry bracket; the upper ends of the lifting screw rods are connected with power output shafts of the lifting adjustment speed reducing motors; lifting screw nuts are fixedly arranged in the centers of the upper ends of the wall plates; the lower ends of the lifting screw rods are screwed in the lifting screw nuts; through holes are formed in the centers of the wall plates; and steel wire wheel assemblies are uniformly distributed in the through holes along the circumferential direction. 3 to 12 steel wire wheels are uniformly distributed at the periphery of a steel pipe to axially coat the external surface of the steel pipe at 360 degrees, rust or the residual oxide layer on the surface of the steel pipe is removed in an axial friction mode by rotating the steel wire wheels, and the flaw detection and paint spraying quality of the steel pipe is ensured; and in addition, concentricity adjustment and radial adjustment can be performed according to the diameter of the steel pipe, and the requirements of derusting steel pipes of different specifications are met.

Description

technical field [0001] The invention belongs to the technical field of metal derusting equipment, and in particular relates to a steel pipe derusting machine. Background technique [0002] Since the surface of the steel pipe is rusted or has a residual oxide layer, which affects the accuracy of flaw detection, and also causes problems such as the steel pipe not being sprayed when painting, the steel pipe manufacturer needs to derust the surface of the steel pipe before carrying out the flaw detection and painting treatment of the steel pipe. deal with. At present, the derusting device on the steel pipe surface is widely used to rotate the derusting device around the steel pipe, which causes the steel pipe to easily rotate with the derusting device, which affects the derusting effect of the steel pipe. Moreover, the structure is complex and the production efficiency is low, which cannot meet the supporting needs of the steel pipe flow production line. Contents of the invent...
