Three roller planet rolling mill roller

TL;DR: In this article, the conical body is divided into four zones such as a rear roll bite zone, a middle centralized deformation zone, head trimming zone, and an outlet round-returning zone.

Abstract: The utility model relates to pressure-processing machine field, in particular to the roller designing for rolling mill, a three-roll planetary mill roller to be exact. The roller provided by the utility model applies to three-roll planetary mill, which overcomes the dithering on the surface of metal rolled tubes and is characterized in that: the conical body is divided into four zones such as a rear roll bite zone, a middle centralized deformation zone, a head trimming zone, and an outlet round-returning zone, Wherein, the roll bite zone is characterized in spiral screw thread, which helps the blank reduce the resistance on its forwarding way and is beneficial for lowering the rolling load in the process of deforming, therefore, the service life of the mold is prolonged, the energy resources saved, and the surface quality of the roller is improved.
