GUIDE DEVICE FOR BLOCK MILL, BLOCK MILL, AND METHOD FOR ROLLING WIRE ROD OR WIRE

摘要

PROBLEM TO BE SOLVED: To enable the rolling of the wire rod or the wire without causing tilt, seizure and disconnection by providing in the guide device plural sets of guide rollers for bundling materials to be rolled, which are moved in following up to the materials to be rolled during rolling. ;SOLUTION: The wire 12 that the diameter of the wire rid, etc., rolled by rolls in a preceding stage is ≥4mm, enters guide rollers 4 in the guide device A. The guide rollers 4 become a state coming into contact with the wire 12 very lightly or a state just before coming into contact with it, and the wire 12 advances further and reaches guide rollers 5. Next, the movements of main arms 7 on the guide rollers 5 side are transmitted to the main arms 7 on the guide rollers 4 side via pivots 6. The main arms 7 on the guide rollers 4 side are lowered to the wire 12, and the support of arm bases 11 and the bonding of the wire 12 by the guide rollers 4 and 5 are started. By this series of movements, the occurrence of misroll caused by an accident that the wire 12 is caught on the inlet side on the guide rollers 4 side, is prevented, and guiding, supporting and bundling can be performed most suitably.;COPYRIGHT: (C)1998,JPO
