Title:
METAL PLATE ROLLING MACHINE AND ROLLING METHOD
Document Type and Number:
WIPO Patent Application WO/2011/122069
Kind Code:
A1
Abstract:
Provided is a rolling machine such that openings between upper and lower work rolls can be set to be large, and that strong and highly responsive force can be provided. For this purpose, the rolling machine, which is for use for metal plates, comprises a pair of work rolls consisting of an upper work roll and a lower work roll; and a pair of reinforcing rolls consisting of an upper reinforcing roll and a lower reinforcing roll which support the upper work roll and the lower work roll, respectively. The rolling machine for use for metal plates is characterized in that hydraulic cylinders which impose increasing bending forces on the upper and lower work rolls, respectively, are disposed on projecting blocks which protrude into a rolling machine housing, that the rolling direction force imposed on the trunk section of the lower work roll is supported by the contact surfaces between the projecting blocks and a lower work roll chock, and that the rolling direction force imposed on the trunk section of the upper work roll is supported by the contact surfaces between an upper work roll chock and a rolling machine housing window located above the projecting blocks.
