Description

Technical Field

[0001] The utility model relates to the field of straightening machine equipment, in particular to a seamless steel pipe straightening device provided with a positioning structure. Background Art

[0002] Seamless steel pipes are made by punching holes through a whole round steel bar. There are no welds on the surface of the steel pipe, which is called seamless steel pipe. The straightening device is an important equipment in steel production. It is used to straighten the uneven materials produced by heat treatment or other processes. The straightening of steel pipes is crucial to product quality. The bent steel pipes are straightened by the straightening device to improve the quality of the steel pipes. When straightening, the existing straightening machine directly places the seamless steel pipe on the straightening roller for straightening. Since the seamless steel pipe does not have a positioning structure during the feeding process, the seamless steel pipe itself will shake significantly when the straightening roller is straightening the seamless steel pipe, which affects the correction effect.
