Title:
ROLLING MACHINE
Document Type and Number:
Japanese Patent JP2008043962
Kind Code:
A
Abstract:
To provide a rolling machine which can improve the stability and accuracy of a rolling operation by reducing the change of the distance between opposed frames by reducing the displacement of outer tie bars by forming the outer tie bars so as to have a shape difficult to bend.
The shape of the outer tie bars 3 is a square shape which opens so as to surround tie bar mounting portions 11c of a pair of opposed frames 11. As a result, the outer tie bars do not bend, and the deformation of the outer tie bars 3 can be greatly reduced even if outward expanding forces are applied to short side portions 3a of the outer tie bars 3 in the rolling operation.
