Abstract
A roll stand for a planetary rolling mill having a housing, and two stationary support members mounted in chocks, with rolling segments and intermediate and work rolls mounted in rotationally driven cages. The support members have a plurality of rolling segments, spaced about an outer surface thereof. By the turning of the support members, the rolling segments can be brought, in each case, into working position. In order to be able to effect a change of the rolling segments while using the favorable torque division of the drive system for the roll cages, the support members (1) are rotatably mounted in their chocks (15) adapted to be clamped (20) in the working position of the rolling segments (16). A drive is selectably engaged to rotate the support member into a new working position.
Claims9
A roll stand for a planetary rolling mill comprising a housing, two stationary support members mounted in chocks with a plurality of rolling segments being distributed over a circumference of said support members and intermediate and working rolls mounted in rotationally driven cages and revolving around said support members, each of said support members being rotatably mounted in said chocks for bringing one of said rolling segments into a working position by rotation of said support member, and means for clamping said support members in said working position of one of said plurality of rolling segments after being rotated.
