Abstract

PURPOSE:To perform eccentric positioning with less parts and high accuracy by using split type eccentric rolls for the backup rolls of multistage cluster rolling mills, and providing means for rotating the eccentric rings of the eccentric rolls in the metal chocks of the backup rolls. CONSTITUTION:In multistage cluster rolling mills, backup rolls 4 are split to plural rolls in the direction intersecting orthogonally with their axial direction. Eccentric rings 15 are interposed between the stationary shafts 5a of metal chocks 5 for the backup rolls and the rolls 4. When pinions 17 are rotated by starting driving motors 16 mounted on the chocks 5, racks 18a, 18b move in opposite directions and sector gears 19a, 19b turn, by which the rings 15 are rotated. This action is accomplished by each of the respective backup rolls except the backup rolls in the end parts. Thus the rolls 4 are pushed out to a projecting shape as a whole, and their crowns are adjusted.

なっている。There is a multi-stage cluster rolling mill that enables cold rolling under high pressure. This multi-stage cluster rolling mill has the advantage that the diameter of the work rolls can be reduced, so high reduction rolling is possible even when the rolling load is small. It becomes larger and the shape of the rolled material becomes defective. For this reason, conventional cluster rolling mills employ shape control devices shown in FIGS. 1 to 4. To explain this next, (ol) is a rolled material, which is rolled progressing in the direction of the arrow. Also (o2)
(02) is a pair of upper and lower work rolls, (03) is a pair of upper and lower intermediate rolls that support each work roll (02), and (04) is a reinforcement that supports each of the same intermediate rolls (o3). The roll is divided into multiple pieces (5 pieces in the drawing) in the direction orthogonal to the axial direction ((4a) to (4e)
reference). In addition, (05) is a metal chock for reinforcing rolls,
(05a) passes through the reinforcing roll (4) and has both ends fixed to the reinforcing roll metal chock (05);
(015) is the fixed shaft (05a) and the reinforcing roll (
