Abstract
Abstract To substantially increase the periods of time between the changing of rolling segments and to reduce the amount of work connected therewith in a roll stand for a planetary rolling mill, chocks in which stationary support bodies having rolling segments are mounted are provided with a square or octagonal disk shape, and each support body, instead of having one rolling segment as known heretofore, is provided with four or eight rolling segments distributed uniformly on its periphery. A turnable rolling ring is, further, provided at each end of each support body.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
70 words
A roll stand for a planetary rolling mill comprising stationary support bodies with rolling segments mounted in chocks, and intermediate and work rolls mounted in cages and rotating around the support bodies, the chocks having a square basic shape, and each support body being provided with four rolling segments distributed uniformly on its periphery and being further provided at each end with a respective turnable rolling ring having a recess.
Claim 2
Dependent Claim
70 words
A roll stand for a planetary rolling mill comprising stationary support bodies with rolling segments mounted in chocks, and intermediate and work rolls mounted in cages and rotating around the support bodies, the chocks having a square basic shape, and each support body being provided with four rolling segments distributed uniformly on its periphery and being further provided at each end with a respective turnable rolling ring having a recess.
Claim 3
Dependent Claim
40 words
A roll stand according to claim 1, further comprising a turning device for turning the respective rolling rings of each support body with respect to the support body, and clamping devices for clamping the rolling rings against the support body.
Claim 4
Dependent Claim
62 words
A roll stand according to claim 2, wherein the rolling rings each has an inner toothing and the turning device comprises a stepping motor mounted outside the chocks, a hydraulic booster connected to the stepping motor, a self-locking gearing connected to the hydraulic booster, and a shaft extending in a hole in the support body and having drive pinions fastened on it.
Claim 5
Dependent Claim
45 words
A roll stand according to claim 2, wherein the clamping devices comprise clamping cylinders with disk springs that are arranged on the support bodies, and tensioning rods; the rolling rings having annular grooves to receive the tensioning rods on a surface facing the support body.
Claim 6
Dependent Claim
39 words
A roll stand according to claim 1, wherein each of the chocks is provided with a pair of ledges that are removably attached to the chocks in a position corresponding to the position of installation of the support bodies.
