The utility model discloses a large-
diameter steel
pipe end
sizing and wall uniformizing device which comprises a first hydraulic oil cylinder, the output end of the first hydraulic oil cylinder is fixedly connected with a first connecting rod, the right side of the first connecting rod is fixedly connected with a baffle, and the right side of the baffle is fixedly connected with a steel
pipe body. And rotating rollers are arranged at the top and the bottom of the outer side of the back face of the steel
pipe body, a
grinding module is arranged at the top of the steel pipe body, and a medium-frequency
induction coil is wound on the surface of the steel pipe body. According to the
sizing and wall uniformizing device, the phenomenon of low efficiency of traditional
sizing and wall uniformizing is changed, the pipe end of the steel pipe body is rolled after being heated, required rolling force is small, the requirement for a hydraulic power
system is lowered, the pipe end of the steel pipe body is heated through the medium-frequency
induction coil, the temperature rising speed is high, the temperature is convenient to control, and the
grinding module is arranged, so that the production efficiency is improved. The required part of the outer surface of the steel pipe body can be ground, and the
adverse effect of the scale on the surface of the pipe end on the sizing uniform wall is eliminated.
